[PATCH v2 0/2] kselftest/seccomp: Convert to KTAP output

by Mark Brown

Currently the seccomp benchmark selftest produces non-standard output, meaning that while it makes a number of checks of the performance it observes this has to be parsed by humans. This means that automated systems running this suite of tests are almost certainly ignoring the results which isn't ideal for spotting problems. Let's rework things so that each check that the program does is reported as a test result to the framework.

[PATCH v10 0/4] RISC-V: mm: Make SV48 the default address space

by Charlie Jenkins

Make sv48 the default address space for mmap as some applications currently depend on this assumption. Users can now select a desired address space using a non-zero hint address to mmap. Previously, requesting the default address space from mmap by passing zero as the hint address would result in using the largest address space possible. Some applications depend on empty bits in the virtual address space, like Go and Java, so this patch provides more flexibility for application developers. -Charlie --- v10: - Move pgtable.h defintions into a no __ASSEMBLY__ region to resolve compilation conflicts (pointed out by Conor) - Will now compile with allmodconfig v9: - Raise the mmap_end default to STACK_TOP_MAX to allow the address space to grow beyond the default of sv48 on sv57 machines as suggested by Alexandre - Some of the mmap macros had unnecessary conditionals that I have removed v8: - Fix RV32 and the RV32 compat mode of RV64 (suggested by Conor) - Extract out addr and base from the mmap macros (suggested by Alexandre) v7: - Changing RLIMIT_STACK inside of an executing program does not trigger arch_pick_mmap_layout(), so rewrite tests to change RLIMIT_STACK from a script before executing tests. RLIMIT_STACK of infinity forces bottomup mmap allocation. - Make arch_get_mmap_base macro more readible by extracting out the rnd calculation. - Use MMAP_MIN_VA_BITS in TASK_UNMAPPED_BASE to support case when mmap attempts to allocate address smaller than DEFAULT_MAP_WINDOW. - Fix incorrect wording in documentation. v6: - Rebase onto the correct base v5: - Minor wording change in documentation - Change some parenthesis in arch_get_mmap_ macros - Added case for addr==0 in arch_get_mmap_ because without this, programs would crash if RLIMIT_STACK was modified before executing the program. This was tested using the libhugetlbfs tests. v4: - Split testcases/document patch into test cases, in-code documentation, and formal documentation patches - Modified the mmap_base macro to be more legible and better represent memory layout - Fixed documentation to better reflect the implmentation - Renamed DEFAULT_VA_BITS to MMAP_VA_BITS - Added additional test case for rlimit changes --- Charlie Jenkins (4): RISC-V: mm: Restrict address space for sv39,sv48,sv57 RISC-V: mm: Add tests for RISC-V mm RISC-V: mm: Update pgtable comment documentation RISC-V: mm: Document mmap changes Documentation/riscv/vm-layout.rst | 22 +++++++ arch/riscv/include/asm/elf.h | 2 +- arch/riscv/include/asm/pgtable.h | 33 ++++++++-- arch/riscv/include/asm/processor.h | 52 +++++++++++++-- tools/testing/selftests/riscv/Makefile | 2 +- tools/testing/selftests/riscv/mm/.gitignore | 2 + tools/testing/selftests/riscv/mm/Makefile | 15 +++++ .../riscv/mm/testcases/mmap_bottomup.c | 35 ++++++++++ .../riscv/mm/testcases/mmap_default.c | 35 ++++++++++ .../selftests/riscv/mm/testcases/mmap_test.h | 64 +++++++++++++++++++ .../selftests/riscv/mm/testcases/run_mmap.sh | 12 ++++ 11 files changed, 261 insertions(+), 13 deletions(-) create mode 100644 tools/testing/selftests/riscv/mm/.gitignore create mode 100644 tools/testing/selftests/riscv/mm/Makefile create mode 100644 tools/testing/selftests/riscv/mm/testcases/mmap_bottomup.c create mode 100644 tools/testing/selftests/riscv/mm/testcases/mmap_default.c create mode 100644 tools/testing/selftests/riscv/mm/testcases/mmap_test.h create mode 100755 tools/testing/selftests/riscv/mm/testcases/run_mmap.sh -- 2.34.1

[PATCH v6 0/3] livepatch: Move modules to selftests and add a new test

by Marcos Paulo de Souza

Changes in v6: - Rebased on top of 70d201a40823 (thanks Alexander Gordeev!) - Resolved a conflict because of 43e8832fed08 being reverted - Resolved a missing static declaration for lp_sys_getpid, since -Wmissing-prototypes warning was enabled. - Retested everything, from running the livepatch selftests from kernel source, running from a directory here the testes were installed (Joe's usecase), and running from a gen_tar'ed directory. All of them executed correctly. - Added Petr review tags (Thanks!) - Link to v5: https://lore.kernel.org/r/20240109-send-lp-kselftests-v5-0-364d59a69f12@sus… Changes in v5: * Fixed an issue found by Joe that copied Kbuild files along with the test modules to the installation directory. * Added Joe Lawrense review tags. Changes in v4: * Documented how to compile the livepatch selftests without running the tests (Joe) * Removed the mention to lib/livepatch on MAINTAINERS file, reported by checkpatch. Changes in v3: * Rebased on top of v6.6-rc5 * The commits messages were improved (Thanks Petr!) * Created TEST_GEN_MODS_DIR variable to point to a directly that contains kernel modules, and adapt selftests to build it before running the test. * Moved test_klp-call_getpid out of test_programs, since the gen_tar would just copy the generated test programs to the livepatches dir, and so scripts relying on test_programs/test_klp-call_getpid will fail. * Added a module_param for klp_pids, describing it's usage. * Simplified the call_getpid program to ignore the return of getpid syscall, since we only want to make sure the process transitions correctly to the patched stated * The test-syscall.sh not prints a log message showing the number of remaining processes to transition into to livepatched state, and check_output expects it to be 0. * Added MODULE_AUTHOR and MODULE_DESCRIPTION to test_klp_syscall.c - Link to v3: https://lore.kernel.org/r/20231031-send-lp-kselftests-v3-0-2b1655c2605f@sus… - Link to v2: https://lore.kernel.org/linux-kselftest/20220630141226.2802-1-mpdesouza@sus… This patchset moves the current kernel testing livepatch modules from lib/livepatches to tools/testing/selftest/livepatch/test_modules, and compiles them as out-of-tree modules before testing. There is also a new test being added. This new test exercises multiple processes calling a syscall, while a livepatch patched the syscall. Why this move is an improvement: * The modules are now compiled as out-of-tree modules against the current running kernel, making them capable of being tested on different systems with newer or older kernels. * Such approach now needs kernel-devel package to be installed, since they are out-of-tree modules. These can be generated by running "make rpm-pkg" in the kernel source. What needs to be solved: * Currently gen_tar only packages the resulting binaries of the tests, and not the sources. For the current approach, the newly added modules would be compiled and then packaged. It works when testing on a system with the same kernel version. But it will fail when running on a machine with different kernel version, since module was compiled against the kernel currently running. This is not a new problem, just aligning the expectations. For the current approach to be truly system agnostic gen_tar would need to include the module and program sources to be compiled in the target systems. Thanks in advance!

[PATCH v2] kselftest/clone3: Make test names for set_tid test stable

by Mark Brown

The test results reported for the clone3_set_tid tests interact poorly with automation for running kselftest since the reported test names include TIDs dynamically allocated at runtime. A lot of automation for running kselftest will compare runs by looking at the test name to identify if the same test is being run so changing names make it look like the testsuite has been updated to include new tests. This makes the results display less clearly and breaks cases like bisection. Address this by providing a brief description of the tests and logging that along with the stable parameters for the test currently logged. The TIDs are already logged separately in existing logging except for the final test which has a new log message added. We also tweak the formatting of the logging of expected/actual values for clarity. There are still issues with the logging of skipped tests (many are simply not logged at all when skipped and all are logged with different names) but these are less disruptive since the skips are all based on not being run as root, a condition likely to be stable for a given test system.

[PATCH v2] selftests: mm: fix map_hugetlb failure on 64K page size systems

by Nico Pache

On systems with 64k page size and 512M huge page sizes, the allocation and test succeeds but errors out at the munmap. As the comment states, munmap will failure if its not HUGEPAGE aligned. This is due to the length of the mapping being 1/2 the size of the hugepage causing the munmap to not be hugepage aligned. Fix this by making the mapping length the full hugepage if the hugepage is larger than the length of the mapping.

[PATCH v1] selftests/mm: ksm_tests should only MADV_HUGEPAGE valid memory

by Ryan Roberts

ksm_tests was previously mmapping a region of memory, aligning the returned pointer to a PMD boundary, then setting MADV_HUGEPAGE, but was setting it past the end of the mmapped area due to not taking the pointer alignment into consideration. Fix this behaviour. Up until commit efa7df3e3bb5 ("mm: align larger anonymous mappings on THP boundaries"), this buggy behavior was (usually) masked because the alignment difference was always less than PMD-size. But since the mentioned commit, `ksm_tests -H -s 100` started failing.

[PATCH] kunit: Mark filter_glob param as rw

by Lucas De Marchi

By allowing the filter_glob parameter to be written to, it's possible to tweak the testsuites that will be executed on new module loads. This makes it easier to run specific tests without having to reload kunit and provides a way to filter tests on real HW even if kunit is builtin. Example for xe driver: 1) Run just 1 test # echo -n xe_bo > /sys/module/kunit/parameters/filter_glob # modprobe -r xe_live_test # modprobe xe_live_test # ls /sys/kernel/debug/kunit/ xe_bo 2) Run all tests # echo \* > /sys/module/kunit/parameters/filter_glob # modprobe -r xe_live_test # modprobe xe_live_test # ls /sys/kernel/debug/kunit/ xe_bo xe_dma_buf xe_migrate xe_mocs References: https://lore.kernel.org/intel-xe/dzacvbdditbneiu3e3fmstjmttcbne44yspumpkd6s… Signed-off-by: Lucas De Marchi <lucas.demarchi(a)intel.com> --- lib/kunit/executor.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/lib/kunit/executor.c b/lib/kunit/executor.c index 1236b3cd2fbb..30ed9d321c19 100644 --- a/lib/kunit/executor.c +++ b/lib/kunit/executor.c @@ -31,7 +31,7 @@ static char *filter_glob_param; static char *filter_param; static char *filter_action_param; -module_param_named(filter_glob, filter_glob_param, charp, 0400); +module_param_named(filter_glob, filter_glob_param, charp, 0600); MODULE_PARM_DESC(filter_glob, "Filter which KUnit test suites/tests run at boot-time, e.g. list* or list*.*del_test"); module_param_named(filter, filter_param, charp, 0400); -- 2.40.1

[PATCH v5 4/4] selftest/bpf: Test a perf bpf program that suppresses side effects.

by Kyle Huey

The test sets a hardware breakpoint and uses a bpf program to suppress the side effects of a perf event sample, including I/O availability signals, SIGTRAPs, and decrementing the event counter limit, if the ip matches the expected value. Then the function with the breakpoint is executed multiple times to test that all effects behave as expected.

[PATCH net v2] selftests: net: fix rps_default_mask with >32 CPUs

[RFC PATCH v3 00/11] Introduce mseal()

by jeffxu＠chromium.org

From: Jeff Xu <jeffxu(a)chromium.org> This patchset proposes a new mseal() syscall for the Linux kernel. In a nutshell, mseal() protects the VMAs of a given virtual memory range against modifications, such as changes to their permission bits. Modern CPUs support memory permissions, such as the read/write (RW) and no-execute (NX) bits. Linux has supported NX since the release of kernel version 2.6.8 in August 2004 [1]. The memory permission feature improves the security stance on memory corruption bugs, as an attacker cannot simply write to arbitrary memory and point the code to it. The memory must be marked with the X bit, or else an exception will occur. Internally, the kernel maintains the memory permissions in a data structure called VMA (vm_area_struct). mseal() additionally protects the VMA itself against modifications of the selected seal type. Memory sealing is useful to mitigate memory corruption issues where a corrupted pointer is passed to a memory management system. For example, such an attacker primitive can break control-flow integrity guarantees since read-only memory that is supposed to be trusted can become writable or .text pages can get remapped. Memory sealing can automatically be applied by the runtime loader to seal .text and .rodata pages and applications can additionally seal security critical data at runtime. A similar feature already exists in the XNU kernel with the VM_FLAGS_PERMANENT [3] flag and on OpenBSD with the mimmutable syscall [4]. Also, Chrome wants to adopt this feature for their CFI work [2] and this patchset has been designed to be compatible with the Chrome use case. The new mseal() is an architecture independent syscall, and with following signature: mseal(void addr, size_t len, unsigned long types, unsigned long flags) addr/len: memory range. Must be continuous/allocated memory, or else mseal() will fail and no VMA is updated. For details on acceptable arguments, please refer to documentation patch (mseal.rst) of this patch set. Those are also fully covered by the selftest. types: bit mask to specify the sealing types. MM_SEAL_BASE MM_SEAL_PROT_PKEY MM_SEAL_DISCARD_RO_ANON MM_SEAL_SEAL The MM_SEAL_BASE: The base package includes the features common to all VMA sealing types. It prevents sealed VMAs from: 1> Unmapping, moving to another location, and shrinking the size, via munmap() and mremap(), can leave an empty space, therefore can be replaced with a VMA with a new set of attributes. 2> Move or expand a different vma into the current location, via mremap(). 3> Modifying sealed VMA via mmap(MAP_FIXED). 4> Size expansion, via mremap(), does not appear to pose any specific risks to sealed VMAs. It is included anyway because the use case is unclear. In any case, users can rely on merging to expand a sealed VMA. We consider the MM_SEAL_BASE feature, on which other sealing features will depend. For instance, it probably does not make sense to seal PROT_PKEY without sealing the BASE, and the kernel will implicitly add SEAL_BASE for SEAL_PROT_PKEY. The MM_SEAL_PROT_PKEY: Seal PROT and PKEY of the address range, i.e. mprotect() and pkey_mprotect() will be denied if the memory is sealed with MM_SEAL_PROT_PKEY. The MM_SEAL_DISCARD_RO_ANON Certain types of madvise() operations are destructive [6], such as MADV_DONTNEED, which can effectively alter region contents by discarding pages, especially when memory is anonymous. This blocks such operations for anonymous memory which is not writable to the user. The MM_SEAL_SEAL MM_SEAL_SEAL denies adding a new seal for an VMA. This is similar to F_SEAL_SEAL in fcntl. The idea that inspired this patch comes from Stephen Röttger’s work in V8 CFI [5]. Chrome browser in ChromeOS will be the first user of this API. Indeed, the Chrome browser has very specific requirements for sealing, which are distinct from those of most applications. For example, in the case of libc, sealing is only applied to read-only (RO) or read-execute (RX) memory segments (such as .text and .RELRO) to prevent them from becoming writable, the lifetime of those mappings are tied to the lifetime of the process. Chrome wants to seal two large address space reservations that are managed by different allocators. The memory is mapped RW- and RWX respectively but write access to it is restricted using pkeys (or in the future ARM permission overlay extensions). The lifetime of those mappings are not tied to the lifetime of the process, therefore, while the memory is sealed, the allocators still need to free or discard the unused memory. For example, with madvise(DONTNEED). However, always allowing madvise(DONTNEED) on this range poses a security risk. For example if a jump instruction crosses a page boundary and the second page gets discarded, it will overwrite the target bytes with zeros and change the control flow. Checking write-permission before the discard operation allows us to control when the operation is valid. In this case, the madvise will only succeed if the executing thread has PKEY write permissions and PKRU changes are protected in software by control-flow integrity. Although the initial version of this patch series is targeting the Chrome browser as its first user, it became evident during upstream discussions that we would also want to ensure that the patch set eventually is a complete solution for memory sealing and compatible with other use cases. The specific scenario currently in mind is glibc's use case of loading and sealing ELF executables. To this end, Stephen is working on a change to glibc to add sealing support to the dynamic linker, which will seal all non-writable segments at startup. Once this work is completed, all applications will be able to automatically benefit from these new protections. -------------------------------------------------------------------- Change history: =============== V3: - Abandon per-syscall approach, (Suggested by Linus Torvalds). - Organize sealing types around their functionality, such as MM_SEAL_BASE, MM_SEAL_PROT_PKEY. - Extend the scope of sealing from calls originated in userspace to both kernel and userspace. (Suggested by Linus Torvalds) - Add seal type support in mmap(). (Suggested by Pedro Falcato) - Add a new sealing type: MM_SEAL_DISCARD_RO_ANON to prevent destructive operations of madvise. (Suggested by Jann Horn and Stephen Röttger) - Make sealed VMAs mergeable. (Suggested by Jann Horn) - Add MAP_SEALABLE to mmap() (Detail see new discussions) - Add documentation - mseal.rst Work in progress: ================= - update man page for mseal() and mmap() Open discussions: ================= Several open discussions from V1/V2 were not incorporated into V3. I believe these are worth more discussion for future versions of this patch series. 1> mseal() vs mimmutable() mseal(bitmasks for multiple seal types) BASE + PROT_PKEY+ MM_SEAL_DISCARD_RO_ANON Apply PROT_PKEY implies BASE, same for DISCARD_RO_ANON mimmutable() (openBSD) This is equal to SEAL_BASE + SEAL_PROT_PKEY in mseal() Plus allowing downgrade from W=>NW (OpenBSD) Doesn’t have MM_SEAL_DISCARD_RO_ANON mimmutable() is designed for memory sealing in libc, and mseal() is designed for both Chrome browser and libc. For the two memory ranges that Chrome browser wants to seal, as discussed previously, the allocator still needs to free or discard memory for the sealed memory. For performance reasons, we have explored two solutions in the past: first, using PKEY-based munmap() [7], and second, separating SEAL_MPROTECT (v1 of this patch set). Recently, we have experimented with an alternative approach that allows us to remove the separation of SEAL_MPROTECT. For those two memory ranges, Chrome browser will use BASE + PROT_PKEY + DISCARD_RO_ANON for all its sealing needs. In the case of libc, the .text segment can be sealed with the BASE and PROT_PKEY, and the RO data segments can be sealed with the BASE + PROT_PKEY + DISCARD_RO_ANON. From a flexibility standpoint, separating BASE out could be beneficial for future extensions of sealing features. For instance, applications might desire downgradable "prot" permissions (X=>NX, W=>NW, R=>NR), which would conflict with SEAL_PROT_PKEY. The more sealing features integrated into a single sealing type, the fewer applications can utilize these features. For example, some applications might programmatically require DISCARD_RO_ANON memory, which would render such VMA unsuitable for sealing. I'd like to get the community's input on this. From Chrome's perspective, the separation isn't as important anymore, at least in the short term. However, I prefer the multiple bits approach because it's more extensible in the long term. 2> mseal() vs mprotect() vs madvise() for setting the seal. mprotect(): Using prot field, but prot supports unset. It's workable, i.e. let applications carry the sealing type and set in all subsequent calls to mprotect(), but it feels like this is an extra thing to care about. madvise(): uses enum, multiple sealing types might require multiple roundtrips. IMO: sealing is a major departure from other memory syscalls because it takes away capabilities. The other memory APIs add behaviors or change attributes, but sealing does the opposite: it reduces capabilities. The name of the syscall, mseal(), can help emphasize the "taking away" part. My second choice would be madvise(). 3> Other: There is also a topic about ptrace/, /proc/self/mem, Userfaultfd, which I think can be followed up using v1 thread, where it has the most context. New discussions topics: ======================= During the development of V3, I had new questions and thoughts and wished to discuss. 1> shm/aio From reading the code, it seems to me that aio/shm can mmap/munmap maps on behalf of userspace, e.g. ksys_shmdt() in shm.c. The lifetime of those mapping are not tied to the lifetime of the process. If those memories are sealed from userspace, then unmap will fail. This isn’t a huge problem, since the memory will eventually be freed at exit or exec. However, it feels like the solution is not complete, because of the leaks in VMA address space during the lifetime of the process. There could be two solutions to address this, which I will discuss later. 2> Brk (heap/stack) Currently, userspace applications can seal parts of the heap by calling malloc() and mseal(). This raises the question of what the expected behavior is when sealing the heap is attempted. let's assume following calls from user space: ptr = malloc(size); mprotect(ptr, size, RO); mseal(ptr, size, SEAL_PROT_PKEY); free(ptr); Technically, before mseal() is added, the user can change the protection of the heap by calling mprotect(RO). As long as the user changes the protection back to RW before free(), the memory can be reused. Adding mseal() into picture, however, the heap is then sealed partially, user can still free it, but the memory remains to be RO, and the result of brk-shrink is nondeterministic, depending on if munmap() will try to free the sealed memory.(brk uses munmap to shrink the heap). 3> Above two cases led to the third topic: There are two options to address the problem mentioned above. Option 1: A “MAP_SEALABLE” flag in mmap(). If a map is created without this flag, the mseal() operation will fail. Applications that are not concerned with sealing will expect their behavior to be unchanged. For those that are concerned, adding a flag at mmap time to opt in is not difficult. For the short term, this solves problems 1 and 2 above. The memory in shm/aio/brk will not have the MAP_SEALABLE flag at mmap(), and the same is true for the heap. Option 2: Add MM_SEAL_SEAL during mmap() It is possible to defensively set MM_SEAL_SEAL for the selected mappings at creation time. Specifically, we can find all the mmaps that we do not want to seal, and add the MM_SEAL_SEAL flag in the mmap() call. The difference between MAP_SEALABLE and MM_SEAL_SEAL is that the first option starts from a small size and incrementally increases, while the second option is the opposite. In my opinion, MAP_SEALABLE is the preferred option. Only a limited set of mappings need to be sealed, and these are typically created by the runtime. For the few dedicated applications that manage their own mappings, such as Chrome, adding an extra flag at mmap() is not a difficult task. It is also a safer option in terms of regression risk. This is the option included in this version. 4> I think it might be possible to seal the stack or other special mappings created at runtime (vdso, vsyscall, vvar). This means we can enforce and seal W^X for certain types of application. For instance, the stack is typically used in read-write mode, but in some cases, it can become executable. To defend against unintented addition of executable bit to stack, we could let the application to seal it. Sealing the heap (for adding X) requires special handling, since the heap can shrink, and shrink is implemented through munmap(). Indeed, it might be possible that all virtual memory accessible to user space, regardless of its usage pattern, could be sealed. However, this would require additional research and development work. ------------------------------------------------------------------------ v2: Use _BITUL to define MM_SEAL_XX type. Use unsigned long for seal type in sys_mseal() and other functions. Remove internal VM_SEAL_XX type and convert_user_seal_type(). Remove MM_ACTION_XX type. Remove caller_origin(ON_BEHALF_OF_XX) and replace with sealing bitmask. Add more comments in code.

lsm_cgroup.c selftest fails to compile when CONFIG_PACKET!=y

by Shung-Hsi Yu

Hi, Compilation of lsm_cgroup.c will fail if the vmlinux.h comes from a kernel that does _not_ have CONFIG_PACKET=y. The reason is that the definition of struct sockaddr_ll is not present in vmlinux.h and the compiler will complain that is has an incomplete type. CLNG-BPF [test_maps] lsm_cgroup.bpf.o progs/lsm_cgroup.c:105:21: error: variable has incomplete type 'struct sockaddr_ll' 105 | struct sockaddr_ll sa = {}; | ^ progs/lsm_cgroup.c:105:9: note: forward declaration of 'struct sockaddr_ll' 105 | struct sockaddr_ll sa = {}; | ^ 1 error generated. While including linux/if_packet.h somehow made the compilation works for me, IIUC this isn't a proper solution because vmlinux.h and kernel headers should not be used at the same time (and would lead to redefinition error when the kernel is built with CONFIG_PACKET=y, e.g. on BPF CI). What would be the suggested way to work around this?

[PATCH v4 4/4] selftest/bpf: Test a perf bpf program that suppresses side effects.

by Kyle Huey

The test sets a hardware breakpoint and uses a bpf program to suppress the side effects of a perf event sample, including I/O availability signals, SIGTRAPs, and decrementing the event counter limit, if the ip matches the expected value.

[PATCH] selftests: mm: fix map_hugetlb failure on 64K page size systems

by Nico Pache

On systems with 64k page size and 512M huge page sizes, the allocation and test succeeds but errors out at the munmap. As the comment states, munmap will failure if its not HUGEPAGE aligned. This is due to the length of the mapping being 1/2 the size of the hugepage causing the munmap to not be hugepage aligned. Fix this by making the mapping length the full hugepage if the hugepage is larger than the length of the mapping.

[PATCH v3 4/4] selftest/bpf: Test a perf bpf program that suppresses side effects.

by Kyle Huey

The test sets a hardware breakpoint and uses a bpf program to suppress the side effects of a perf event sample, including I/O availability signals, SIGTRAPs, and decrementing the event counter limit, if the ip matches the expected value. Then the function with the breakpoint is executed multiple times to test that all effects behave as expected.

[PATCH v7 00/39] arm64/gcs: Provide support for GCS in userspace

by Mark Brown

The arm64 Guarded Control Stack (GCS) feature provides support for hardware protected stacks of return addresses, intended to provide hardening against return oriented programming (ROP) attacks and to make it easier to gather call stacks for applications such as profiling. When GCS is active a secondary stack called the Guarded Control Stack is maintained, protected with a memory attribute which means that it can only be written with specific GCS operations. The current GCS pointer can not be directly written to by userspace. When a BL is executed the value stored in LR is also pushed onto the GCS, and when a RET is executed the top of the GCS is popped and compared to LR with a fault being raised if the values do not match. GCS operations may only be performed on GCS pages, a data abort is generated if they are not. The combination of hardware enforcement and lack of extra instructions in the function entry and exit paths should result in something which has less overhead and is more difficult to attack than a purely software implementation like clang's shadow stacks. This series implements support for use of GCS by userspace, along with support for use of GCS within KVM guests. It does not enable use of GCS by either EL1 or EL2, this will be implemented separately. Executables are started without GCS and must use a prctl() to enable it, it is expected that this will be done very early in application execution by the dynamic linker or other startup code. For dynamic linking this will be done by checking that everything in the executable is marked as GCS compatible. x86 has an equivalent feature called shadow stacks, this series depends on the x86 patches for generic memory management support for the new guarded/shadow stack page type and shares APIs as much as possible. As there has been extensive discussion with the wider community around the ABI for shadow stacks I have as far as practical kept implementation decisions close to those for x86, anticipating that review would lead to similar conclusions in the absence of strong reasoning for divergence. The main divergence I am concious of is that x86 allows shadow stack to be enabled and disabled repeatedly, freeing the shadow stack for the thread whenever disabled, while this implementation keeps the GCS allocated after disable but refuses to reenable it. This is to avoid races with things actively walking the GCS during a disable, we do anticipate that some systems will wish to disable GCS at runtime but are not aware of any demand for subsequently reenabling it. x86 uses an arch_prctl() to manage enable and disable, since only x86 and S/390 use arch_prctl() a generic prctl() was proposed[1] as part of a patch set for the equivalent RISC-V Zicfiss feature which I initially adopted fairly directly but following review feedback has been revised quite a bit. We currently maintain the x86 pattern of implicitly allocating a shadow stack for threads started with shadow stack enabled, there has been some discussion of removing this support and requiring the use of clone3() with explicit allocation of shadow stacks instead. I have no strong feelings either way, implicit allocation is not really consistent with anything else we do and creates the potential for errors around thread exit but on the other hand it is existing ABI on x86 and minimises the changes needed in userspace code. There is an open issue with support for CRIU, on x86 this required the ability to set the GCS mode via ptrace. This series supports configuring mode bits other than enable/disable via ptrace but it needs to be confirmed if this is sufficient. The series depends on support for shadow stacks in clone3(), that series includes the addition of ARCH_HAS_USER_SHADOW_STACK. https://lore.kernel.org/r/20231120-clone3-shadow-stack-v3-0-a7b8ed3e2acc@ke… It also depends on the addition of more waitpid() flags to nolibc: https://lore.kernel.org/r/20231023-nolibc-waitpid-flags-v2-1-b09d096f091f@k… You can see a branch with the full set of dependencies against Linus' tree at: https://git.kernel.org/pub/scm/linux/kernel/git/broonie/misc.git arm64-gcs [1] https://lore.kernel.org/lkml/20230213045351.3945824-1-debug@rivosinc.com/ Signed-off-by: Mark Brown <broonie(a)kernel.org> --- Changes in v7: -

[PATCH bpf-next] bpf: Allow setting SO_TIMESTAMPING* with bpf_setsockopt()

by Jörn-Thorben Hinz

A BPF application, e.g., a TCP congestion control, might benefit from or even require precise (=hardware) packet timestamps. These timestamps are already available through __sk_buff.hwtstamp and bpf_sock_ops.skb_hwtstamp, but could not be requested: BPF programs were not allowed to set SO_TIMESTAMPING* on sockets. Enable BPF programs to actively request the generation of timestamps from a stream socket. The also required ioctl(SIOCSHWTSTAMP) on the network device must still be done separately, in user space. This patch had previously been submitted in a two-part series (first link below). The second patch has been independently applied in commit 7f6ca95d16b9 ("net: Implement missing getsockopt(SO_TIMESTAMPING_NEW)") (second link below). On the earlier submission, there was the open question whether to only allow, thus enforce, SO_TIMESTAMPING_NEW in this patch: For a BPF program, this won't make a difference: A timestamp, when accessed through the fields mentioned above, is directly read from skb_shared_info.hwtstamps, independent of the places where NEW/OLD is relevant. See bpf_convert_ctx_access() besides others. I am unsure, though, when it comes to the interconnection of user space and BPF "space", when both are interested in the timestamps. I think it would cause an unsolvable conflict when user space is bound to use SO_TIMESTAMPING_OLD with a BPF program only allowed to set SO_TIMESTAMPING_NEW *on the same socket*? Please correct me if I'm mistaken.

[PATCH 00/15] KVM RISC-V report more ISA extensions through ONE_REG

by Anup Patel

This extends the KVM RISC-V ONE_REG interface to report more ISA extensions namely: Zbz, scalar crypto, vector crypto, Zfh[min], Zihintntl, Zvfh[min], and Zfa. This series depends upon the "riscv: report more ISA extensions through hwprobe" series.from Clement. (Link: https://lore.kernel.org/lkml/20231114141256.126749-1-cleger@rivosinc.com/) To test these patches, use KVMTOOL from the riscv_more_exts_v1 branch at: https://github.com/avpatel/kvmtool.git These patches can also be found in the riscv_kvm_more_exts_v1 branch at: https://github.com/avpatel/linux.git Anup Patel (15): KVM: riscv: selftests: Generate ISA extension reg_list using macros RISC-V: KVM: Allow Zbc extension for Guest/VM KVM: riscv: selftests: Add Zbc extension to get-reg-list test RISC-V: KVM: Allow scalar crypto extensions for Guest/VM KVM: riscv: selftests: Add scaler crypto extensions to get-reg-list test RISC-V: KVM: Allow vector crypto extensions for Guest/VM KVM: riscv: selftests: Add vector crypto extensions to get-reg-list test RISC-V: KVM: Allow Zfh[min] extensions for Guest/VM KVM: riscv: selftests: Add Zfh[min] extensions to get-reg-list test RISC-V: KVM: Allow Zihintntl extension for Guest/VM KVM: riscv: selftests: Add Zihintntl extension to get-reg-list test RISC-V: KVM: Allow Zvfh[min] extensions for Guest/VM KVM: riscv: selftests: Add Zvfh[min] extensions to get-reg-list test RISC-V: KVM: Allow Zfa extension for Guest/VM KVM: riscv: selftests: Add Zfa extension to get-reg-list test arch/riscv/include/uapi/asm/kvm.h | 27 ++ arch/riscv/kvm/vcpu_onereg.c | 54 +++ .../selftests/kvm/riscv/get-reg-list.c | 439 ++++++++---------- 3 files changed, 265 insertions(+), 255 deletions(-) -- 2.34.1

As a followup to commit 03fb8565c880 ("selftests: bonding: add missing build configs"), add more networking-specific config options which are needed for bonding tests. For testing, I used the minimal config generated by virtme-ng and I added the options in the config file. All bonding tests passed.

[PATCH net 6/6] selftests: mlxsw: qos_pfc: Adjust the test to support 8 lanes

by Petr Machata

From: Amit Cohen <amcohen(a)nvidia.com> 'qos_pfc' test checks PFC behavior. The idea is to limit the traffic using a shaper somewhere in the flow of the packets. In this area, the buffer is smaller than the buffer at the beginning of the flow, so it fills up until there is no more space left. The test configures there PFC which is supposed to notice that the headroom is filling up and send PFC Xoff to indicate the transmitter to stop sending traffic for the priorities sharing this PG. The Xon/Xoff threshold is auto-configured and always equal to 2*(MTU rounded up to cell size). Even after sending the PFC Xoff packet, traffic will keep arriving until the transmitter receives and processes the PFC packet. This amount of traffic is known as the PFC delay allowance. Currently the buffer for the delay traffic is configured as 100KB. The MTU in the test is 10KB, therefore the threshold for Xoff is about 20KB. This allows 80KB extra to be stored in this buffer. 8-lane ports use two buffers among which the configured buffer is split, the Xoff threshold then applies to each buffer in parallel. The test does not take into account the behavior of 8-lane ports, when the ports are configured to 400Gbps with 8 lanes or 800Gbps with 8 lanes, packets are dropped and the test fails. Check if the relevant ports use 8 lanes, in such case double the size of the buffer, as the headroom is split half-half.

[RFC PATCH v4 0/4] Introduce mseal()

by jeffxu＠chromium.org

From: Jeff Xu <jeffxu(a)chromium.org> This is V4 of the patch, the patch has improved significantly since V1, thanks to diverse inputs, a few discussions remain, please read those in the open discussion section of v4 of change history. ----------------------------------------------------------------- This patchset proposes a new mseal() syscall for the Linux kernel. In a nutshell, mseal() protects the VMAs of a given virtual memory range against modifications, such as changes to their permission bits. Modern CPUs support memory permissions, such as the read/write (RW) and no-execute (NX) bits. Linux has supported NX since the release of kernel version 2.6.8 in August 2004 [1]. The memory permission feature improves the security stance on memory corruption bugs, as an attacker cannot simply write to arbitrary memory and point the code to it. The memory must be marked with the X bit, or else an exception will occur. Internally, the kernel maintains the memory permissions in a data structure called VMA (vm_area_struct). mseal() additionally protects the VMA itself against modifications of the selected seal type. Memory sealing is useful to mitigate memory corruption issues where a corrupted pointer is passed to a memory management system. For example, such an attacker primitive can break control-flow integrity guarantees since read-only memory that is supposed to be trusted can become writable or .text pages can get remapped. Memory sealing can automatically be applied by the runtime loader to seal .text and .rodata pages and applications can additionally seal security critical data at runtime. A similar feature already exists in the XNU kernel with the VM_FLAGS_PERMANENT [3] flag and on OpenBSD with the mimmutable syscall [4]. Also, Chrome wants to adopt this feature for their CFI work [2] and this patchset has been designed to be compatible with the Chrome use case. Two system calls are involved in sealing the map: mmap() and mseal(). The new mseal() is an syscall on 64 bit CPU, and with following signature: int mseal(void addr, size_t len, unsigned long flags) addr/len: memory range. flags: reserved. mseal() blocks following operations for the given memory range. 1> Unmapping, moving to another location, and shrinking the size, via munmap() and mremap(), can leave an empty space, therefore can be replaced with a VMA with a new set of attributes. 2> Moving or expanding a different VMA into the current location, via mremap(). 3> Modifying a VMA via mmap(MAP_FIXED). 4> Size expansion, via mremap(), does not appear to pose any specific risks to sealed VMAs. It is included anyway because the use case is unclear. In any case, users can rely on merging to expand a sealed VMA. 5> mprotect() and pkey_mprotect(). 6> Some destructive madvice() behaviors (e.g. MADV_DONTNEED) for anonymous memory, when users don't have write permission to the memory. Those behaviors can alter region contents by discarding pages, effectively a memset(0) for anonymous memory. In addition: mmap() has two related changes. The PROT_SEAL bit in prot field of mmap(). When present, it marks the map sealed since creation. The MAP_SEALABLE bit in the flags field of mmap(). When present, it marks the map as sealable. A map created without MAP_SEALABLE will not support sealing, i.e. mseal() will fail. Applications that don't care about sealing will expect their behavior unchanged. For those that need sealing support, opt-in by adding MAP_SEALABLE in mmap(). The idea that inspired this patch comes from Stephen Röttger’s work in V8 CFI [5]. Chrome browser in ChromeOS will be the first user of this API. Indeed, the Chrome browser has very specific requirements for sealing, which are distinct from those of most applications. For example, in the case of libc, sealing is only applied to read-only (RO) or read-execute (RX) memory segments (such as .text and .RELRO) to prevent them from becoming writable, the lifetime of those mappings are tied to the lifetime of the process. Chrome wants to seal two large address space reservations that are managed by different allocators. The memory is mapped RW- and RWX respectively but write access to it is restricted using pkeys (or in the future ARM permission overlay extensions). The lifetime of those mappings are not tied to the lifetime of the process, therefore, while the memory is sealed, the allocators still need to free or discard the unused memory. For example, with madvise(DONTNEED). However, always allowing madvise(DONTNEED) on this range poses a security risk. For example if a jump instruction crosses a page boundary and the second page gets discarded, it will overwrite the target bytes with zeros and change the control flow. Checking write-permission before the discard operation allows us to control when the operation is valid. In this case, the madvise will only succeed if the executing thread has PKEY write permissions and PKRU changes are protected in software by control-flow integrity. Although the initial version of this patch series is targeting the Chrome browser as its first user, it became evident during upstream discussions that we would also want to ensure that the patch set eventually is a complete solution for memory sealing and compatible with other use cases. The specific scenario currently in mind is glibc's use case of loading and sealing ELF executables. To this end, Stephen is working on a change to glibc to add sealing support to the dynamic linker, which will seal all non-writable segments at startup. Once this work is completed, all applications will be able to automatically benefit from these new protections. -------------------------------------------------------------------- Change history: =============== V4: (Suggested by Linus Torvalds) - new signature: mseal(start,len,flags) - 32 bit is not supported. vm_seal is removed, use vm_flags instead. - single bit in vm_flags for sealed state. - CONFIG_MSEAL kernel config is removed. - single bit of PROT_SEAL in the "Prot" field of mmap(). Other changes: - update selftest (Suggested by Muhammad Usama Anjum) - update documentation. Open discussions: ================= Below discussion were brought up in V3, and did not receive any input: the one important to this patch is MAP_SEALABLE in mmap(), which is in current version of patch, list here for input/comments. --------------------------------------------------------------------- During the development of V3, I had new questions and thoughts and wished to discuss. 1> shm/aio From reading the code, it seems to me that aio/shm can mmap/munmap maps on behalf of userspace, e.g. ksys_shmdt() in shm.c. The lifetime of those mapping are not tied to the lifetime of the process. If those memories are sealed from userspace, then unmap will fail. This isn’t a huge problem, since the memory will eventually be freed at exit or exec. However, it feels like the solution is not complete, because of the leaks in VMA address space during the lifetime of the process. 2> Brk (heap/stack) Currently, userspace applications can seal parts of the heap by calling malloc() and mseal(). This raises the question of what the expected behavior is when sealing the heap is attempted. let's assume following calls from user space: ptr = malloc(size); mprotect(ptr, size, RO); mseal(ptr, size, SEAL_PROT_PKEY); free(ptr); Technically, before mseal() is added, the user can change the protection of the heap by calling mprotect(RO). As long as the user changes the protection back to RW before free(), the memory can be reused. Adding mseal() into picture, however, the heap is then sealed partially, user can still free it, but the memory remains to be RO, and the result of brk-shrink is nondeterministic, depending on if munmap() will try to free the sealed memory.(brk uses munmap to shrink the heap). 3> Above two cases led to the third topic: There one option to address the problem mentioned above. Option 1: A “MAP_SEALABLE” flag in mmap(). If a map is created without this flag, the mseal() operation will fail. Applications that are not concerned with sealing will expect their behavior to be unchanged. For those that are concerned, adding a flag at mmap time to opt in is not difficult. For the short term, this solves problems 1 and 2 above. The memory in shm/aio/brk will not have the MAP_SEALABLE flag at mmap(), and the same is true for the heap. If we choose not to go with path, all mapping will by default sealable. We could document above mentioned limitations so devs are more careful at the time to choose what memory to seal. I think deny of service through mseal() by attacker is probably not a concern, if attackers have access to mseal() and unsealed memory, then they can also do other harmful thing to the memory, such as munmap, etc. 4> I think it might be possible to seal the stack or other special mappings created at runtime (vdso, vsyscall, vvar). This means we can enforce and seal W^X for certain types of application. For instance, the stack is typically used in read-write mode, but in some cases, it can become executable. To defend against unintented addition of executable bit to stack, we could let the application to seal it. Sealing the heap (for adding X) requires special handling, since the heap can shrink, and shrink is implemented through munmap(). Indeed, it might be possible that all virtual memory accessible to user space, regardless of its usage pattern, could be sealed. However, this would require additional research and development work. ===================================================================== V3: - Abandon per-syscall approach, (Suggested by Linus Torvalds). - Organize sealing types around their functionality, such as MM_SEAL_BASE, MM_SEAL_PROT_PKEY. - Extend the scope of sealing from calls originated in userspace to both kernel and userspace. (Suggested by Linus Torvalds) - Add seal type support in mmap(). (Suggested by Pedro Falcato) - Add a new sealing type: MM_SEAL_DISCARD_RO_ANON to prevent destructive operations of madvise. (Suggested by Jann Horn and Stephen Röttger) - Make sealed VMAs mergeable. (Suggested by Jann Horn) - Add MAP_SEALABLE to mmap() - Add documentation - mseal.rst https://lore.kernel.org/linux-mm/20231212231706.2680890-2-jeffxu@chromium.o… v2: Use _BITUL to define MM_SEAL_XX type. Use unsigned long for seal type in sys_mseal() and other functions. Remove internal VM_SEAL_XX type and convert_user_seal_type(). Remove MM_ACTION_XX type. Remove caller_origin(ON_BEHALF_OF_XX) and replace with sealing bitmask. Add more comments in code.

[PATCH AUTOSEL 6.1 05/68] selftests/bpf: Fix issues in setup_classid_environment()

by Sasha Levin

From: Yafang Shao <laoar.shao(a)gmail.com> [ Upstream commit 4849775587844e44d215289c425bcd70f315efe7 ] If the net_cls subsystem is already mounted, attempting to mount it again in setup_classid_environment() will result in a failure with the error code EBUSY. Despite this, tmpfs will have been successfully mounted at /sys/fs/cgroup/net_cls. Consequently, the /sys/fs/cgroup/net_cls directory will be empty, causing subsequent setup operations to fail.

by Sasha Levin

From: Yonghong Song <yonghong.song(a)linux.dev> [ Upstream commit b16904fd9f01b580db357ef2b1cc9e86d89576c2 ] With latest upstream llvm18, the following test cases failed: $ ./test_progs -j #13/2 bpf_cookie/multi_kprobe_link_api:FAIL #13/3 bpf_cookie/multi_kprobe_attach_api:FAIL #13 bpf_cookie:FAIL #77 fentry_fexit:FAIL #78/1 fentry_test/fentry:FAIL #78 fentry_test:FAIL #82/1 fexit_test/fexit:FAIL #82 fexit_test:FAIL #112/1 kprobe_multi_test/skel_api:FAIL #112/2 kprobe_multi_test/link_api_addrs:FAIL [...] #112 kprobe_multi_test:FAIL #356/17 test_global_funcs/global_func17:FAIL #356 test_global_funcs:FAIL Further analysis shows llvm upstream patch [1] is responsible for the above failures. For example, for function bpf_fentry_test7() in net/bpf/test_run.c, without [1], the asm code is: 0000000000000400 <bpf_fentry_test7>: 400: f3 0f 1e fa endbr64 404: e8 00 00 00 00 callq 0x409 <bpf_fentry_test7+0x9> 409: 48 89 f8 movq %rdi, %rax 40c: c3 retq 40d: 0f 1f 00 nopl (%rax) ... and with [1], the asm code is: 0000000000005d20 <bpf_fentry_test7.specialized.1>: 5d20: e8 00 00 00 00 callq 0x5d25 <bpf_fentry_test7.specialized.1+0x5> 5d25: c3 retq ... and <bpf_fentry_test7.specialized.1> is called instead of <bpf_fentry_test7> and this caused test failures for #13/#77 etc. except #356. For test case #356/17, with [1] (progs/test_global_func17.c)), the main prog looks like: 0000000000000000 <global_func17>: 0: b4 00 00 00 2a 00 00 00 w0 = 0x2a 1: 95 00 00 00 00 00 00 00 exit ... which passed verification while the test itself expects a verification failure. Let us add 'barrier_var' style asm code in both places to prevent function specialization which caused selftests failure.

[PATCH AUTOSEL 6.7 031/108] bpf: Fix a few selftest failures due to llvm18 change

by Sasha Levin

From: Yonghong Song <yonghong.song(a)linux.dev> [ Upstream commit b16904fd9f01b580db357ef2b1cc9e86d89576c2 ] With latest upstream llvm18, the following test cases failed: $ ./test_progs -j #13/2 bpf_cookie/multi_kprobe_link_api:FAIL #13/3 bpf_cookie/multi_kprobe_attach_api:FAIL #13 bpf_cookie:FAIL #77 fentry_fexit:FAIL #78/1 fentry_test/fentry:FAIL #78 fentry_test:FAIL #82/1 fexit_test/fexit:FAIL #82 fexit_test:FAIL #112/1 kprobe_multi_test/skel_api:FAIL #112/2 kprobe_multi_test/link_api_addrs:FAIL [...] #112 kprobe_multi_test:FAIL #356/17 test_global_funcs/global_func17:FAIL #356 test_global_funcs:FAIL Further analysis shows llvm upstream patch [1] is responsible for the above failures. For example, for function bpf_fentry_test7() in net/bpf/test_run.c, without [1], the asm code is: 0000000000000400 <bpf_fentry_test7>: 400: f3 0f 1e fa endbr64 404: e8 00 00 00 00 callq 0x409 <bpf_fentry_test7+0x9> 409: 48 89 f8 movq %rdi, %rax 40c: c3 retq 40d: 0f 1f 00 nopl (%rax) ... and with [1], the asm code is: 0000000000005d20 <bpf_fentry_test7.specialized.1>: 5d20: e8 00 00 00 00 callq 0x5d25 <bpf_fentry_test7.specialized.1+0x5> 5d25: c3 retq ... and <bpf_fentry_test7.specialized.1> is called instead of <bpf_fentry_test7> and this caused test failures for #13/#77 etc. except #356. For test case #356/17, with [1] (progs/test_global_func17.c)), the main prog looks like: 0000000000000000 <global_func17>: 0: b4 00 00 00 2a 00 00 00 w0 = 0x2a 1: 95 00 00 00 00 00 00 00 exit ... which passed verification while the test itself expects a verification failure. Let us add 'barrier_var' style asm code in both places to prevent function specialization which caused selftests failure.

[PATCH AUTOSEL 6.7 008/108] selftests/bpf: Fix issues in setup_classid_environment()

by Sasha Levin

From: Yafang Shao <laoar.shao(a)gmail.com> [ Upstream commit 4849775587844e44d215289c425bcd70f315efe7 ] If the net_cls subsystem is already mounted, attempting to mount it again in setup_classid_environment() will result in a failure with the error code EBUSY. Despite this, tmpfs will have been successfully mounted at /sys/fs/cgroup/net_cls. Consequently, the /sys/fs/cgroup/net_cls directory will be empty, causing subsequent setup operations to fail.

[PATCH AUTOSEL 6.7 006/108] selftests/bpf: Fix pyperf180 compilation failure with clang18

by Sasha Levin

From: Yonghong Song <yonghong.song(a)linux.dev> [ Upstream commit 100888fb6d8a185866b1520031ee7e3182b173de ] With latest clang18 (main branch of llvm-project repo), when building bpf selftests, [~/work/bpf-next (master)]$ make -C tools/testing/selftests/bpf LLVM=1 -j The following compilation error happens: fatal error: error in backend: Branch target out of insn range ...

Code generation ... The compilation failure only happens to cpu=v2 and cpu=v3. cpu=v4 is okay since cpu=v4 supports 32-bit branch target offset. The above failure is due to upstream llvm patch [1] where some inlining behavior are changed in clang18. To workaround the issue, previously all 180 loop iterations are fully unrolled. The bpf macro __BPF_CPU_VERSION__ (implemented in clang18 recently) is used to avoid unrolling changes if cpu=v4. If __BPF_CPU_VERSION__ is not available and the compiler is clang18, the unrollng amount is unconditionally reduced.

[PATCH v11 0/8] Add iommufd nesting (part 2/2)

by Yi Liu

Nested translation is a hardware feature that is supported by many modern IOMMU hardwares. It has two stages (stage-1, stage-2) address translation to get access to the physical address. stage-1 translation table is owned by userspace (e.g. by a guest OS), while stage-2 is owned by kernel. Changes to stage-1 translation table should be followed by an IOTLB invalidation. Take Intel VT-d as an example, the stage-1 translation table is I/O page table. As the below diagram shows, guest I/O page table pointer in GPA (guest physical address) is passed to host and be used to perform the stage-1 address translation. Along with it, modifications to present mappings in the guest I/O page table should be followed with an IOTLB invalidation. .-------------. .---------------------------. | vIOMMU | | Guest I/O page table | | | '---------------------------' .----------------/ | PASID Entry |--- PASID cache flush --+ '-------------' | | | V | | I/O page table pointer in GPA '-------------' Guest ------| Shadow |---------------------------|-------- v v v Host .-------------. .------------------------. | pIOMMU | | FS for GIOVA->GPA | | | '------------------------' .----------------/ | | PASID Entry | V (Nested xlate) '----------------\.----------------------------------. | | | SS for GPA->HPA, unmanaged domain| | | '----------------------------------' '-------------' Where: - FS = First stage page tables - SS = Second stage page tables <Intel VT-d Nested translation> This series is based on the first part which was merged [1], this series is to add the cache invalidation interface or the userspace to invalidate cache after modifying the stage-1 page table. This includes both the iommufd changes and the VT-d driver changes. Complete code can be found in [2], QEMU could can be found in [3]. At last, this is a team work together with Nicolin Chen, Lu Baolu. Thanks them for the help. ^_^. Look forward to your feedbacks. [1] https://lore.kernel.org/linux-iommu/20231026044216.64964-1-yi.l.liu@intel.c… - merged [2] https://github.com/yiliu1765/iommufd/tree/iommufd_nesting [3] https://github.com/yiliu1765/qemu/tree/zhenzhong/wip/iommufd_nesting_rfcv1 Change log: v11: - Drop hw_error field in vtd cache invalidation uapi. devTLB invalidation error is a serious security emergency requiring the host kernel to handle. No need to expose it to userspace (especially given existing VMs doesn't issue devTLB invalidation at all). - The vtd qi_submit_sync() and related callers are reverted back to the original state due to above drop. - Align with the vtd path, drop the hw_error reporting in mock driver and selftest as well since selftest is a demo of the real driver. - Drop iommu_respond_struct_to_user_array() since no more driver want to respond single entry in the user_array. - Two typos from Wubinbin v10: https://lore.kernel.org/all/20240102143834.146165-1-yi.l.liu@intel.com/ - Minor tweak to patch 07 (Kevin) - Rebase on top of 6.7-rc8 v9: https://lore.kernel.org/linux-iommu/20231228150629.13149-1-yi.l.liu@intel.c… - Add a test case which sets both IOMMU_TEST_INVALIDATE_FLAG_ALL and IOMMU_TEST_INVALIDATE_FLAG_TRIGGER_ERROR in flags, and expect to succeed and see an 'error'. (Kevin) - Returns -ETIMEOUT in qi_check_fault() if caller is interested with the fault when timeout happens. If not, the qi_submit_sync() will keep retry hence unable to report the error back to user. For now, only the user cache invalidation path has interest on the time out error. So this change only affects the user cache invalidation path. Other path will still hang in qi_submit_sync() when timeout happens. (Kevin) v8: https://lore.kernel.org/linux-iommu/20231227161354.67701-1-yi.l.liu@intel.c… - Pass invalidation hint to the cache invalidation helper in the cache_invalidate_user op path (Kevin) - Move the devTLB invalidation out of info->iommu loop (Kevin, Weijiang) - Clear *fault per restart in qi_submit_sync() to avoid acroos submission error accumulation. (Kevin) - Define the vtd cache invalidation uapi structure in separate patch (Kevin) - Rename inv_error to be hw_error (Kevin) - Rename 'reqs_uptr', 'req_type', 'req_len' and 'req_num' to be 'data_uptr', 'data_type', "entry_len' and 'entry_num" (Kevin) - Allow user to set IOMMU_TEST_INVALIDATE_FLAG_ALL and IOMMU_TEST_INVALIDATE_FLAG_TRIGGER_ERROR in the same time (Kevin) v7: https://lore.kernel.org/linux-iommu/20231221153948.119007-1-yi.l.liu@intel.… - Remove domain->ops->cache_invalidate_user check in hwpt alloc path due to failure in bisect (Baolu) - Remove out_driver_error_code from struct iommu_hwpt_invalidate after discussion in v6. Should expect per-entry error code. - Rework the selftest cache invalidation part to report a per-entry error - Allow user to pass in an empty array to have a try-and-fail mechanism for user to check if a given req_type is supported by the kernel (Jason) - Define a separate enum type for cache invalidation data (Jason) - Fix the IOMMU_HWPT_INVALIDATE to always update the req_num field before returning (Nicolin) - Merge the VT-d nesting part 2/2 https://lore.kernel.org/linux-iommu/20231117131816.24359-1-yi.l.liu@intel.c… into this series to avoid defining empty enum in the middle of the series. The major difference is adding the VT-d related invalidation uapi structures together with the generic data structures in patch 02 of this series. - VT-d driver was refined to report ICE/ITE error from the bottom cache invalidation submit helpers, hence the cache_invalidate_user op could report such errors via the per-entry error field to user. VT-d driver will not stop the invalidation array walking due to the ICE/ITE errors as such errors are defined by VT-d spec, userspace should be able to handle it and let the real user (say Virtual Machine) know about it. But for other errors like invalid uapi data structure configuration, memory copy failure, such errors should stop the array walking as it may have more issues if go on. - Minor fixes per Jason and Kevin's review comments v6: https://lore.kernel.org/linux-iommu/20231117130717.19875-1-yi.l.liu@intel.c… - No much change, just rebase on top of 6.7-rc1 as part 1/2 is merged v5: https://lore.kernel.org/linux-iommu/20231020092426.13907-1-yi.l.liu@intel.c… - Split the iommufd nesting series into two parts of alloc_user and invalidation (Jason) - Split IOMMUFD_OBJ_HW_PAGETABLE to IOMMUFD_OBJ_HWPT_PAGING/_NESTED, and do the same with the structures/alloc()/abort()/destroy(). Reworked the selftest accordingly too. (Jason) - Move hwpt/data_type into struct iommu_user_data from standalone op arguments. (Jason) - Rename hwpt_type to be data_type, the HWPT_TYPE to be HWPT_ALLOC_DATA, _TYPE_DEFAULT to be _ALLOC_DATA_NONE (Jason, Kevin) - Rename iommu_copy_user_data() to iommu_copy_struct_from_user() (Kevin) - Add macro to the iommu_copy_struct_from_user() to calculate min_size (Jason) - Fix two bugs spotted by ZhaoYan v4: https://lore.kernel.org/linux-iommu/20230921075138.124099-1-yi.l.liu@intel.… - Separate HWPT alloc/destroy/abort functions between user-managed HWPTs and kernel-managed HWPTs - Rework invalidate uAPI to be a multi-request array-based design - Add a struct iommu_user_data_array and a helper for driver to sanitize and copy the entry data from user space invalidation array - Add a patch fixing TEST_LENGTH() in selftest program - Drop IOMMU_RESV_IOVA_RANGES patches - Update kdoc and inline comments - Drop the code to add IOMMU_RESV_SW_MSI to kernel-managed HWPT in nested translation, this does not change the rule that resv regions should only be added to the kernel-managed HWPT. The IOMMU_RESV_SW_MSI stuff will be added in later series as it is needed only by SMMU so far. v3: https://lore.kernel.org/linux-iommu/20230724110406.107212-1-yi.l.liu@intel.… - Add new uAPI things in alphabetical order - Pass in "enum iommu_hwpt_type hwpt_type" to op->domain_alloc_user for sanity, replacing the previous op->domain_alloc_user_data_len solution - Return ERR_PTR from domain_alloc_user instead of NULL - Only add IOMMU_RESV_SW_MSI to kernel-managed HWPT in nested translation (Kevin) - Add IOMMU_RESV_IOVA_RANGES to report resv iova ranges to userspace hence userspace is able to exclude the ranges in the stage-1 HWPT (e.g. guest I/O page table). (Kevin) - Add selftest coverage for the new IOMMU_RESV_IOVA_RANGES ioctl - Minor changes per Kevin's inputs v2: https://lore.kernel.org/linux-iommu/20230511143844.22693-1-yi.l.liu@intel.c… - Add union iommu_domain_user_data to include all user data structures to avoid passing void * in kernel APIs. - Add iommu op to return user data length for user domain allocation - Rename struct iommu_hwpt_alloc::data_type to be hwpt_type - Store the invalidation data length in iommu_domain_ops::cache_invalidate_user_data_len - Convert cache_invalidate_user op to be int instead of void - Remove @data_type in struct iommu_hwpt_invalidate - Remove out_hwpt_type_bitmap in struct iommu_hw_info hence drop patch 08 of v1 v1: https://lore.kernel.org/linux-iommu/20230309080910.607396-1-yi.l.liu@intel.… Thanks, Yi Liu Lu Baolu (2): iommu: Add cache_invalidate_user op iommu/vt-d: Add iotlb flush for nested domain Nicolin Chen (4): iommu: Add iommu_copy_struct_from_user_array helper iommufd/selftest: Add mock_domain_cache_invalidate_user support iommufd/selftest: Add IOMMU_TEST_OP_MD_CHECK_IOTLB test op iommufd/selftest: Add coverage for IOMMU_HWPT_INVALIDATE ioctl Yi Liu (2): iommufd: Add IOMMU_HWPT_INVALIDATE iommufd: Add data structure for Intel VT-d stage-1 cache invalidation drivers/iommu/intel/nested.c | 88 ++++++++++ drivers/iommu/iommufd/hw_pagetable.c | 41 +++++ drivers/iommu/iommufd/iommufd_private.h | 10 ++ drivers/iommu/iommufd/iommufd_test.h | 23 +++ drivers/iommu/iommufd/main.c | 3 + drivers/iommu/iommufd/selftest.c | 76 +++++++++ include/linux/iommu.h | 79 +++++++++ include/uapi/linux/iommufd.h | 79 +++++++++ tools/testing/selftests/iommu/iommufd.c | 152 ++++++++++++++++++ tools/testing/selftests/iommu/iommufd_utils.h | 57 +++++++ 10 files changed, 608 insertions(+) -- 2.34.1

[PATCH 00/12] selftests/net: Add TCP-AO tests

by Dmitry Safonov

Hi, An essential part of any big kernel submissions is selftests. At the beginning of TCP-AO project, I made patches to fcnal-test.sh and nettest.c to have the benefits of easy refactoring, early noticing breakages, putting a moat around the code, documenting and designing uAPI. While tests based on fcnal-test.sh/nettest.c provided initial testing* and were very easy to add, the pile of TCP-AO quickly grew out of one-binary + shell-script testing. The design of the TCP-AO testing is a bit different than one-big selftest binary as I did previously in net/ipsec.c. I found it beneficial to avoid implementing a tests runner/scheduler and delegate it to the user or Makefile. The approach is very influenced by CRIU/ZDTM testing[1]: it provides a static library with helper functions and selftest binaries that create specific scenarios. I also tried to utilize kselftest.h. test_init() function does all needed preparations. To not leave any traces after a selftest exists, it creates a network namespace and if the test wants to establish a TCP connection, a child netns. The parent and child netns have veth pair with proper ip addresses and routes set up. Both peers, the client and server are different pthreads. The treading model was chosen over forking mostly by easiness of cleanup on a failure: no need to search for children, handle SIGCHLD, make sure not to wait for a dead peer to perform anything, etc. Any thread that does exit() naturally kills the tests, sweet! The selftests are compiled currently in two variants: ipv4 and ipv6. Ipv4-mapped-ipv6 addresses might be a third variant to add, but it's not there in this version. As pretty much all tests are shared between two address families, most of the code can be shared, too. To differ in code what kind of test is running, Makefile supplies -DIPV6_TEST to compiler and ifdeffery in tests can do things that have to be different between address families. This is similar to TARGETS_C_BOTHBITS in x86 selftests and also to tests code sharing in CRIU/ZDTM. The total number of tests is 832. From them rst_ipv{4,6} has currently one flaky subtest, that may fail: > not ok 9 client connection was not reset: 0 I'll investigate what happens there. Also, unsigned-md5_ipv{4,6} are flaky because of netns counter checks: it doesn't expect that there may be retransmitted TCP segments from a previous sub-selftest. That will be fixed. Besides, key-management_ipv{4,6} has 3 sub-tests passing with XFAIL: > ok 15 # XFAIL listen() after current/rnext keys set: the socket has current/rnext keys: 100:200 > ok 16 # XFAIL listen socket, delete current key from before listen(): failed to delete the key 100:100 -16 > ok 17 # XFAIL listen socket, delete rnext key from before listen(): failed to delete the key 200:200 -16 ... > # Totals: pass:117 fail:0 xfail:3 xpass:0 skip:0 error:0 Those need some more kernel work to pass instead of xfail.

As well as their interaction with VRFs and AO_REQUIRED flag. There are certainly more test scenarios that can be added, but even so, I'm pretty happy that this much of TCP-AO functionality and uAPIs got covered. These selftests were iteratively developed by me during TCP-AO kernel upstreaming and the resulting kernel patches would have been worse without having these tests. They provided the user-side perspective but also allowed safer refactoring with less possibility of introducing a regression. Now it's time to use them to dig a moat around the TCP-AO code! There are also people from other network companies that work on TCP-AO (+testing), so sharing these selftests will allow them to contribute and may benefit from their efforts.

[PATCH v2 0/6] IOMMUFD: Deliver IO page faults to user space

by Lu Baolu

Hi folks, This series implements the functionality of delivering IO page faults to user space through the IOMMUFD framework for nested translation. Nested translation is a hardware feature that supports two-stage translation tables for IOMMU. The second-stage translation table is managed by the host VMM, while the first-stage translation table is owned by user space. This allows user space to control the IOMMU mappings for its devices. When an IO page fault occurs on the first-stage translation table, the IOMMU hardware can deliver the page fault to user space through the IOMMUFD framework. User space can then handle the page fault and respond to the device top-down through the IOMMUFD. This allows user space to implement its own IO page fault handling policies. User space indicates its capability of handling IO page faults by setting the IOMMU_HWPT_ALLOC_IOPF_CAPABLE flag when allocating a hardware page table (HWPT). IOMMUFD will then set up its infrastructure for page fault delivery. On a successful return of HWPT allocation, the user can retrieve and respond to page faults by reading and writing to the file descriptor (FD) returned in out_fault_fd. The iommu selftest framework has been updated to test the IO page fault delivery and response functionality. This series is based on the latest implementation of nested translation under discussion [1] and the page fault handling framework refactoring in the IOMMU core [2].

[PATCH 0/3] vfio-pci support pasid attach/detach

by Yi Liu

This adds the pasid attach/detach uAPIs for userspace to attach/detach a PASID of a device to/from a given ioas/hwpt. Only vfio-pci driver is enabled in this series. After this series, PASID-capable devices bound with vfio-pci can report PASID capability to userspace and VM to enable PASID usages like Shared Virtual Addressing (SVA). This series first adds the helpers for pasid attach in vfio core and then add the device cdev ioctls for pasid attach/detach, finally exposes the device PASID capability to user. It depends on iommufd pasid attach/detach series [1]. Complete code can be found at [2], tested with a draft Qemu branch[3] [1] https://lore.kernel.org/linux-iommu/20231127063428.127436-1-yi.l.liu@intel.… [2] https://github.com/yiliu1765/iommufd/tree/iommufd_pasid [3] https://github.com/yiliu1765/qemu/tree/zhenzhong/wip/iommufd_nesting_rfcv1%… Change log: v1: - Report PASID capability via VFIO_DEVICE_FEATURE (Alex) rfc: https://lore.kernel.org/linux-iommu/20230926093121.18676-1-yi.l.liu@intel.c… Regards, Yi Liu Kevin Tian (1): vfio-iommufd: Support pasid [at|de]tach for physical VFIO devices Yi Liu (2): vfio: Add VFIO_DEVICE_PASID_[AT|DE]TACH_IOMMUFD_PT vfio: Report PASID capability via VFIO_DEVICE_FEATURE ioctl drivers/vfio/device_cdev.c | 45 +++++++++++++++++++++ drivers/vfio/iommufd.c | 48 ++++++++++++++++++++++ drivers/vfio/pci/vfio_pci.c | 2 + drivers/vfio/pci/vfio_pci_core.c | 47 ++++++++++++++++++++++ drivers/vfio/vfio.h | 4 ++ drivers/vfio/vfio_main.c | 8 ++++ include/linux/vfio.h | 11 ++++++ include/uapi/linux/vfio.h | 68 ++++++++++++++++++++++++++++++++ 8 files changed, 233 insertions(+) -- 2.34.1

Conform the layout, informational and status messages to TAP. No functional change is intended other than the layout of output messages.

[PATCH v6 0/4] Introduce mseal()

by jeffxu＠chromium.org

From: Jeff Xu <jeffxu(a)google.com> This patchset proposes a new mseal() syscall for the Linux kernel. In a nutshell, mseal() protects the VMAs of a given virtual memory range against modifications, such as changes to their permission bits. Modern CPUs support memory permissions, such as the read/write (RW) and no-execute (NX) bits. Linux has supported NX since the release of kernel version 2.6.8 in August 2004 [1]. The memory permission feature improves the security stance on memory corruption bugs, as an attacker cannot simply write to arbitrary memory and point the code to it. The memory must be marked with the X bit, or else an exception will occur. Internally, the kernel maintains the memory permissions in a data structure called VMA (vm_area_struct). mseal() additionally protects the VMA itself against modifications of the selected seal type. Memory sealing is useful to mitigate memory corruption issues where a corrupted pointer is passed to a memory management system. For example, such an attacker primitive can break control-flow integrity guarantees since read-only memory that is supposed to be trusted can become writable or .text pages can get remapped. Memory sealing can automatically be applied by the runtime loader to seal .text and .rodata pages and applications can additionally seal security critical data at runtime. A similar feature already exists in the XNU kernel with the VM_FLAGS_PERMANENT [3] flag and on OpenBSD with the mimmutable syscall [4]. Also, Chrome wants to adopt this feature for their CFI work [2] and this patchset has been designed to be compatible with the Chrome use case. Two system calls are involved in sealing the map: mmap() and mseal(). The new mseal() is an syscall on 64 bit CPU, and with following signature: int mseal(void addr, size_t len, unsigned long flags) addr/len: memory range. flags: reserved. mseal() blocks following operations for the given memory range. 1> Unmapping, moving to another location, and shrinking the size, via munmap() and mremap(), can leave an empty space, therefore can be replaced with a VMA with a new set of attributes. 2> Moving or expanding a different VMA into the current location, via mremap(). 3> Modifying a VMA via mmap(MAP_FIXED). 4> Size expansion, via mremap(), does not appear to pose any specific risks to sealed VMAs. It is included anyway because the use case is unclear. In any case, users can rely on merging to expand a sealed VMA. 5> mprotect() and pkey_mprotect(). 6> Some destructive madvice() behaviors (e.g. MADV_DONTNEED) for anonymous memory, when users don't have write permission to the memory. Those behaviors can alter region contents by discarding pages, effectively a memset(0) for anonymous memory. In addition: mmap() has two related changes. The PROT_SEAL bit in prot field of mmap(). When present, it marks the map sealed since creation. The MAP_SEALABLE bit in the flags field of mmap(). When present, it marks the map as sealable. A map created without MAP_SEALABLE will not support sealing, i.e. mseal() will fail. Applications that don't care about sealing will expect their behavior unchanged. For those that need sealing support, opt-in by adding MAP_SEALABLE in mmap(). The idea that inspired this patch comes from Stephen Röttger’s work in V8 CFI [5]. Chrome browser in ChromeOS will be the first user of this API. Indeed, the Chrome browser has very specific requirements for sealing, which are distinct from those of most applications. For example, in the case of libc, sealing is only applied to read-only (RO) or read-execute (RX) memory segments (such as .text and .RELRO) to prevent them from becoming writable, the lifetime of those mappings are tied to the lifetime of the process. Chrome wants to seal two large address space reservations that are managed by different allocators. The memory is mapped RW- and RWX respectively but write access to it is restricted using pkeys (or in the future ARM permission overlay extensions). The lifetime of those mappings are not tied to the lifetime of the process, therefore, while the memory is sealed, the allocators still need to free or discard the unused memory. For example, with madvise(DONTNEED). However, always allowing madvise(DONTNEED) on this range poses a security risk. For example if a jump instruction crosses a page boundary and the second page gets discarded, it will overwrite the target bytes with zeros and change the control flow. Checking write-permission before the discard operation allows us to control when the operation is valid. In this case, the madvise will only succeed if the executing thread has PKEY write permissions and PKRU changes are protected in software by control-flow integrity. Although the initial version of this patch series is targeting the Chrome browser as its first user, it became evident during upstream discussions that we would also want to ensure that the patch set eventually is a complete solution for memory sealing and compatible with other use cases. The specific scenario currently in mind is glibc's use case of loading and sealing ELF executables. To this end, Stephen is working on a change to glibc to add sealing support to the dynamic linker, which will seal all non-writable segments at startup. Once this work is completed, all applications will be able to automatically benefit from these new protections.

[PATCH bpf-next v3 0/3] Annotate kfuncs in .BTF_ids section

by Daniel Xu

=== Description === This is a bpf-treewide change that annotates all kfuncs as such inside .BTF_ids. This annotation eventually allows us to automatically generate kfunc prototypes from bpftool. We store this metadata inside a yet-unused flags field inside struct btf_id_set8 (thanks Kumar!). pahole will be taught where to look. More details about the full chain of events are available in commit 3's description. The accompanying pahole changes (still needs some cleanup) can be viewed here on this "frozen" branch [0]. [0]: https://github.com/danobi/pahole/tree/kfunc_btf-mailed === Changelog === Changes from v2: * Only WARN() for vmlinux kfuncs Changes from v1: * Move WARN_ON() up a call level * Also return error when kfunc set is not properly tagged * Use BTF_KFUNCS_START/END instead of flags * Rename BTF_SET8_KFUNC to BTF_SET8_KFUNCS Daniel Xu (3): bpf: btf: Support flags for BTF_SET8 sets bpf: btf: Add BTF_KFUNCS_START/END macro pair bpf: treewide: Annotate BPF kfuncs in BTF drivers/hid/bpf/hid_bpf_dispatch.c | 8 +++---- fs/verity/measure.c | 4 ++-- include/linux/btf_ids.h | 21 +++++++++++++++---- kernel/bpf/btf.c | 8 +++++++ kernel/bpf/cpumask.c | 4 ++-- kernel/bpf/helpers.c | 8 +++---- kernel/bpf/map_iter.c | 4 ++-- kernel/cgroup/rstat.c | 4 ++-- kernel/trace/bpf_trace.c | 8 +++---- net/bpf/test_run.c | 8 +++---- net/core/filter.c | 16 +++++++------- net/core/xdp.c | 4 ++-- net/ipv4/bpf_tcp_ca.c | 4 ++-- net/ipv4/fou_bpf.c | 4 ++-- net/ipv4/tcp_bbr.c | 4 ++-- net/ipv4/tcp_cubic.c | 4 ++-- net/ipv4/tcp_dctcp.c | 4 ++-- net/netfilter/nf_conntrack_bpf.c | 4 ++-- net/netfilter/nf_nat_bpf.c | 4 ++-- net/xfrm/xfrm_interface_bpf.c | 4 ++-- net/xfrm/xfrm_state_bpf.c | 4 ++-- .../selftests/bpf/bpf_testmod/bpf_testmod.c | 8 +++---- 22 files changed, 81 insertions(+), 60 deletions(-) -- 2.42.1

[PATCH bpf-next v2 00/15] Improvements for tracking scalars in the BPF verifier

by Maxim Mikityanskiy

From: Maxim Mikityanskiy <maxim(a)isovalent.com> The goal of this series is to extend the verifier's capabilities of tracking scalars when they are spilled to stack, especially when the spill or fill is narrowing. It also contains a fix by Eduard for infinite loop detection and a state pruning optimization by Eduard that compensates for a verification complexity regression introduced by tracking unbounded scalars. These improvements reduce the surface of false rejections that I saw while working on Cilium codebase. Patch 1 (Maxim): Fix for an existing test, it will matter later in the series. Patches 2-3 (Eduard): Fixes for false rejections in infinite loop detection that happen in the selftests when my patches are applied. Patches 4-5 (Maxim): Fix the inconsistency of find_equal_scalars that was possible if 32-bit spills were made. Patches 6-11 (Maxim): Support the case when boundary checks are first performed after the register was spilled to the stack. Patches 12-13 (Maxim): Support narrowing fills. Patches 14-15 (Eduard): Optimization for state pruning in stacksafe() to mitigate the verification complexity regression. veristat -e file,prog,states -f '!states_diff<50' -f '!states_pct<10' -f '!states_a<10' -f '!states_b<10' -C ... * Without patch 14: File Program States (A) States (B) States (DIFF) -------------------- ------------ ---------- ---------- ---------------- bpf_xdp.o tail_lb_ipv6 3877 2936 -941 (-24.27%) pyperf180.bpf.o on_event 8422 10456 +2034 (+24.15%) pyperf600.bpf.o on_event 22259 37319 +15060 (+67.66%) pyperf600_iter.bpf.o on_event 400 540 +140 (+35.00%) strobemeta.bpf.o on_event 4702 13435 +8733 (+185.73%) * With patch 14: File Program States (A) States (B) States (DIFF) -------------------- ------------ ---------- ---------- -------------- bpf_xdp.o tail_lb_ipv6 3877 2937 -940 (-24.25%) pyperf600_iter.bpf.o on_event 400 500 +100 (+25.00%) v2 changes: Fixed comments in patch 1, moved endianness checks to header files in patch 12 where possible, added Eduard's ACKs.

[PATCH] selftests/livepatch: fix and refactor new dmesg message code

by Joe Lawrence

The livepatching kselftests rely on comparing expected vs. observed dmesg output. After each test, new dmesg entries are determined by the 'comm' utility comparing a saved, pre-test copy of dmesg to post-test dmesg output. Alexander reports that the 'comm --nocheck-order -13' invocation used by the tests can be confused when dmesg entry timestamps vary in magnitude (ie, "[ 98.820331]" vs. "[ 100.031067]"), in which case, additional messages are reported as new. The unexpected entries then spoil the test results. Instead of relying on 'comm' or 'diff' to determine new testing dmesg entries, refactor the code: - pre-test : log a unique canary dmesg entry - test : run tests, log messages - post-test : filter dmesg starting from pre-test message Reported-by: Alexander Gordeev <agordeev(a)linux.ibm.com> Closes: https://lore.kernel.org/live-patching/ZYAimyPYhxVA9wKg@li-008a6a4c-3549-11b… Signed-off-by: Joe Lawrence <joe.lawrence(a)redhat.com> --- .../testing/selftests/livepatch/functions.sh | 37 +++++++++---------- 1 file changed, 17 insertions(+), 20 deletions(-) diff --git a/tools/testing/selftests/livepatch/functions.sh b/tools/testing/selftests/livepatch/functions.sh index c8416c54b463..b1fd7362c2fe 100644 --- a/tools/testing/selftests/livepatch/functions.sh +++ b/tools/testing/selftests/livepatch/functions.sh @@ -42,17 +42,6 @@ function die() { exit 1 } -# save existing dmesg so we can detect new content -function save_dmesg() { - SAVED_DMESG=$(mktemp --tmpdir -t klp-dmesg-XXXXXX) - dmesg > "$SAVED_DMESG" -} - -# cleanup temporary dmesg file from save_dmesg() -function cleanup_dmesg_file() { - rm -f "$SAVED_DMESG" -} - function push_config() { DYNAMIC_DEBUG=$(grep '^kernel/livepatch' /sys/kernel/debug/dynamic_debug/control | \ awk -F'[: ]' '{print "file " $1 " line " $2 " " $4}') @@ -99,7 +88,6 @@ function set_ftrace_enabled() { function cleanup() { pop_config - cleanup_dmesg_file } # setup_config - save the current config and set a script exit trap that @@ -280,7 +268,15 @@ function set_pre_patch_ret { function start_test { local test="$1" - save_dmesg + # Dump something unique into the dmesg log, then stash the entry + # in LAST_DMESG.

[PATCH 0/3] Update LLVM Phabricator and Bugzilla links

by Nathan Chancellor

This series updates all instances of LLVM Phabricator and Bugzilla links to point to GitHub commits directly and LLVM's Bugzilla to GitHub issue shortlinks respectively. I split up the Phabricator patch into BPF selftests and the rest of the kernel in case the BPF folks want to take it separately from the rest of the series, there are obviously no dependency issues in that case. The Bugzilla change was mechanical enough and should have no conflicts. I am aiming this at Andrew and CC'ing other lists, in case maintainers want to chime in, but I think this is pretty uncontroversial (famous last words...). --- Nathan Chancellor (3): selftests/bpf: Update LLVM Phabricator links arch and include: Update LLVM Phabricator links treewide: Update LLVM Bugzilla links arch/arm64/Kconfig | 4 +-- arch/powerpc/Makefile | 4 +-- arch/powerpc/kvm/book3s_hv_nested.c | 2 +- arch/riscv/Kconfig | 2 +- arch/riscv/include/asm/ftrace.h | 2 +- arch/s390/include/asm/ftrace.h | 2 +- arch/x86/power/Makefile | 2 +- crypto/blake2b_generic.c | 2 +- drivers/firmware/efi/libstub/Makefile | 2 +- drivers/gpu/drm/amd/amdgpu/sdma_v4_4_2.c | 2 +- drivers/media/test-drivers/vicodec/codec-fwht.c | 2 +- drivers/regulator/Kconfig | 2 +- include/asm-generic/vmlinux.lds.h | 2 +- include/linux/compiler-clang.h | 2 +- lib/Kconfig.kasan | 2 +- lib/raid6/Makefile | 2 +- lib/stackinit_kunit.c | 2 +- mm/slab_common.c | 2 +- net/bridge/br_multicast.c | 2 +- security/Kconfig | 2 +- tools/testing/selftests/bpf/README.rst | 32 +++++++++++----------- tools/testing/selftests/bpf/prog_tests/xdpwall.c | 2 +- .../selftests/bpf/progs/test_core_reloc_type_id.c | 2 +- 23 files changed, 40 insertions(+), 40 deletions(-) --- base-commit: 0dd3ee31125508cd67f7e7172247f05b7fd1753a change-id: 20240109-update-llvm-links-d03f9d649e1e Best regards, -- Nathan Chancellor <nathan(a)kernel.org>

[PATCH V13 0/7] amd-pstate preferred core

by Meng Li

Hi all: The core frequency is subjected to the process variation in semiconductors. Not all cores are able to reach the maximum frequency respecting the infrastructure limits. Consequently, AMD has redefined the concept of maximum frequency of a part. This means that a fraction of cores can reach maximum frequency. To find the best process scheduling policy for a given scenario, OS needs to know the core ordering informed by the platform through highest performance capability register of the CPPC interface. Earlier implementations of amd-pstate preferred core only support a static core ranking and targeted performance. Now it has the ability to dynamically change the preferred core based on the workload and platform conditions and accounting for thermals and aging. Amd-pstate driver utilizes the functions and data structures provided by the ITMT architecture to enable the scheduler to favor scheduling on cores which can be get a higher frequency with lower voltage. We call it amd-pstate preferred core. Here sched_set_itmt_core_prio() is called to set priorities and sched_set_itmt_support() is called to enable ITMT feature. Amd-pstate driver uses the highest performance value to indicate the priority of CPU. The higher value has a higher priority. Amd-pstate driver will provide an initial core ordering at boot time. It relies on the CPPC interface to communicate the core ranking to the operating system and scheduler to make sure that OS is choosing the cores with highest performance firstly for scheduling the process. When amd-pstate driver receives a message with the highest performance change, it will update the core ranking. Changes from V12->V13: - ACPI: CPPC: - - modify commit message. - - modify handle function of the notify(0x85). - cpufreq: amd-pstate: - - implement update_limits() callback function. - x86: - - pick up Acked-By flag added by Petkov.

by Christoph Muellner

From: Christoph Müllner <christoph.muellner(a)vrull.eu> When building the RISC-V selftests with a riscv32 compiler I ran into a couple of compiler warnings. While riscv32 support for these tests is questionable, the fixes are so trivial that it is probably best to simply apply them.

[PATCH v2] KVM: selftests: Fix the dirty_log_test semaphore imbalance

by Shaoqin Huang

When execute the dirty_log_test on some aarch64 machine, it sometimes trigger the ASSERT: ==== Test Assertion Failure ==== dirty_log_test.c:384: dirty_ring_vcpu_ring_full pid=14854 tid=14854 errno=22 - Invalid argument 1 0x00000000004033eb: dirty_ring_collect_dirty_pages at dirty_log_test.c:384 2 0x0000000000402d27: log_mode_collect_dirty_pages at dirty_log_test.c:505 3 (inlined by) run_test at dirty_log_test.c:802 4 0x0000000000403dc7: for_each_guest_mode at guest_modes.c:100 5 0x0000000000401dff: main at dirty_log_test.c:941 (discriminator 3) 6 0x0000ffff9be173c7: ?? ??:0 7 0x0000ffff9be1749f: ?? ??:0 8 0x000000000040206f: _start at ??:? Didn't continue vcpu even without ring full The dirty_log_test fails when execute the dirty-ring test, this is because the sem_vcpu_cont and the sem_vcpu_stop is non-zero value when execute the dirty_ring_collect_dirty_pages() function. When those two sem_t variables are non-zero, the dirty_ring_wait_vcpu() at the beginning of the dirty_ring_collect_dirty_pages() will not wait for the vcpu to stop, but continue to execute the following code. In this case, before vcpu stop, if the dirty_ring_vcpu_ring_full is true, and the dirty_ring_collect_dirty_pages() has passed the check for the dirty_ring_vcpu_ring_full but hasn't execute the check for the continued_vcpu, the vcpu stop, and set the dirty_ring_vcpu_ring_full to false. Then dirty_ring_collect_dirty_pages() will trigger the ASSERT. Why sem_vcpu_cont and sem_vcpu_stop can be non-zero value? It's because the dirty_ring_before_vcpu_join() execute the sem_post(&sem_vcpu_cont) at the end of each dirty-ring test. It can cause two cases: 1. sem_vcpu_cont be non-zero. When we set the host_quit to be true, the vcpu_worker directly see the host_quit to be true, it quit. So the log_mode_before_vcpu_join() function will set the sem_vcpu_cont to 1, since the vcpu_worker has quit, it won't consume it. 2. sem_vcpu_stop be non-zero. When we set the host_quit to be true, the vcpu_worker has entered the guest state, the next time it exit from guest state, it will set the sem_vcpu_stop to 1, and then see the host_quit, no one will consume the sem_vcpu_stop. When execute more and more dirty-ring tests, the sem_vcpu_cont and sem_vcpu_stop can be larger and larger, which makes many code paths don't wait for the sem_t. Thus finally cause the problem. To fix this problem, we can wait a while before set the host_quit to true, which gives the vcpu time to enter the guest state, so it will exit again. Then we can wait the vcpu to exit, and let it continue again, then the vcpu will see the host_quit. Thus the sem_vcpu_cont and sem_vcpu_stop will be both zero when test finished.

[PATCH] selftests/net/tcp-ao: Use LDLIBS instead of LDFLAGS

by Dmitry Safonov

The rules to link selftests are: > $(OUTPUT)/%_ipv4: %.c > $(LINK.c) $^ $(LDLIBS) -o $@ > > $(OUTPUT)/%_ipv6: %.c > $(LINK.c) -DIPV6_TEST $^ $(LDLIBS) -o $@ The intel test robot uses only selftest's Makefile, not the top linux Makefile: > make W=1 O=/tmp/kselftest -C tools/testing/selftests So, $(LINK.c) is determined by environment, rather than by kernel Makefiles. On my machine (as well as other people that ran tcp-ao selftests) GNU/Make implicit definition does use $(LDFLAGS): > [dima@Mindolluin ~]$ make -p -f/dev/null | grep '^LINK.c\>' > make: *** No targets. Stop. > LINK.c = $(CC) $(CFLAGS) $(CPPFLAGS) $(LDFLAGS) $(TARGET_ARCH) But, according to build robot report, it's not the case for them. While I could just avoid using pre-defined $(LINK.c), it's also used by selftests/lib.mk by default. Anyways, according to GNU/Make documentation [1], I should have used $(LDLIBS) instead of $(LDFLAGS) in the first place, so let's just do it: > LDFLAGS > Extra flags to give to compilers when they are supposed to invoke > the linker, ‘ld’, such as -L. Libraries (-lfoo) should be added > to the LDLIBS variable instead. > LDLIBS > Library flags or names given to compilers when they are supposed > to invoke the linker, ‘ld’. LOADLIBES is a deprecated (but still > supported) alternative to LDLIBS. Non-library linker flags, such > as -L, should go in the LDFLAGS variable.

Re: [PATCH v14 10/12] selftests/landlock: Add network tests

by Muhammad Usama Anjum

Hi Konstantin, There are some errors being reported in KernelCI: https://linux.kernelci.org/test/plan/id/657ab2240c761c0bd1e134ee/ The following sub-tests are failing: landlock_net_test_protocol_no_sandbox_with_ipv6_tcp_bind_unspec landlock_net_test_protocol_no_sandbox_with_ipv6_udp_bind_unspec landlock_net_test_protocol_tcp_sandbox_with_ipv6_udp_bind_unspec From my initial investigation, I can see that these failures are coming from just finding the wrong return error code (-97 instead of -22). It may be test's issue or the kernel's, not sure yet.

[PATCH v5 0/3] livepatch: Move modules to selftests and add a new test

by Marcos Paulo de Souza

Changes in v5: * Fixed an issue found by Joe that copied Kbuild files along with the test modules to the installation directory. * Added Joe Lawrense review tags. Changes in v4: * Documented how to compile the livepatch selftests without running the tests (Joe) * Removed the mention to lib/livepatch on MAINTAINERS file, reported by checkpatch. Changes in v3: * Rebased on top of v6.6-rc5 * The commits messages were improved (Thanks Petr!) * Created TEST_GEN_MODS_DIR variable to point to a directly that contains kernel modules, and adapt selftests to build it before running the test. * Moved test_klp-call_getpid out of test_programs, since the gen_tar would just copy the generated test programs to the livepatches dir, and so scripts relying on test_programs/test_klp-call_getpid will fail. * Added a module_param for klp_pids, describing it's usage. * Simplified the call_getpid program to ignore the return of getpid syscall, since we only want to make sure the process transitions correctly to the patched stated * The test-syscall.sh not prints a log message showing the number of remaining processes to transition into to livepatched state, and check_output expects it to be 0. * Added MODULE_AUTHOR and MODULE_DESCRIPTION to test_klp_syscall.c - Link to v3: https://lore.kernel.org/r/20231031-send-lp-kselftests-v3-0-2b1655c2605f@sus… - Link to v2: https://lore.kernel.org/linux-kselftest/20220630141226.2802-1-mpdesouza@sus… This patchset moves the current kernel testing livepatch modules from lib/livepatches to tools/testing/selftest/livepatch/test_modules, and compiles them as out-of-tree modules before testing. There is also a new test being added. This new test exercises multiple processes calling a syscall, while a livepatch patched the syscall. Why this move is an improvement: * The modules are now compiled as out-of-tree modules against the current running kernel, making them capable of being tested on different systems with newer or older kernels. * Such approach now needs kernel-devel package to be installed, since they are out-of-tree modules. These can be generated by running "make rpm-pkg" in the kernel source. What needs to be solved: * Currently gen_tar only packages the resulting binaries of the tests, and not the sources. For the current approach, the newly added modules would be compiled and then packaged. It works when testing on a system with the same kernel version. But it will fail when running on a machine with different kernel version, since module was compiled against the kernel currently running. This is not a new problem, just aligning the expectations. For the current approach to be truly system agnostic gen_tar would need to include the module and program sources to be compiled in the target systems. Thanks in advance!

[PATCH V12 0/7] amd-pstate preferred core

by Meng Li

Hi all: The core frequency is subjected to the process variation in semiconductors. Not all cores are able to reach the maximum frequency respecting the infrastructure limits. Consequently, AMD has redefined the concept of maximum frequency of a part. This means that a fraction of cores can reach maximum frequency. To find the best process scheduling policy for a given scenario, OS needs to know the core ordering informed by the platform through highest performance capability register of the CPPC interface. Earlier implementations of amd-pstate preferred core only support a static core ranking and targeted performance. Now it has the ability to dynamically change the preferred core based on the workload and platform conditions and accounting for thermals and aging. Amd-pstate driver utilizes the functions and data structures provided by the ITMT architecture to enable the scheduler to favor scheduling on cores which can be get a higher frequency with lower voltage. We call it amd-pstate preferred core. Here sched_set_itmt_core_prio() is called to set priorities and sched_set_itmt_support() is called to enable ITMT feature. Amd-pstate driver uses the highest performance value to indicate the priority of CPU. The higher value has a higher priority. Amd-pstate driver will provide an initial core ordering at boot time. It relies on the CPPC interface to communicate the core ranking to the operating system and scheduler to make sure that OS is choosing the cores with highest performance firstly for scheduling the process. When amd-pstate driver receives a message with the highest performance change, it will update the core ranking. Changes from V11->V12: - all: - - pick up Reviewed-By flag added by Perry. - cpufreq: amd-pstate: - - rebase the latest linux-next and fixed conflicts. - - fixed the issue about cpudata without init in amd_pstate_update_highest_perf(). Changes from V10->V11: - cpufreq: amd-pstate: - - according Perry's commnts, I replace the string with str_enabled_disable(). Changes from V9->V10: - cpufreq: amd-pstate: - - add judgement for highest_perf. When it is less than 255, the preferred core feature is enabled. And it will set the priority. - - deleset "static u32 max_highest_perf" etc, because amd p-state perferred coe does not require specail process for hotpulg.

[PATCH v8 00/10] Add iommufd nesting (part 2/2)

by Yi Liu

Nested translation is a hardware feature that is supported by many modern IOMMU hardwares. It has two stages (stage-1, stage-2) address translation to get access to the physical address. stage-1 translation table is owned by userspace (e.g. by a guest OS), while stage-2 is owned by kernel. Changes to stage-1 translation table should be followed by an IOTLB invalidation. Take Intel VT-d as an example, the stage-1 translation table is I/O page table. As the below diagram shows, guest I/O page table pointer in GPA (guest physical address) is passed to host and be used to perform the stage-1 address translation. Along with it, modifications to present mappings in the guest I/O page table should be followed with an IOTLB invalidation. .-------------. .---------------------------. | vIOMMU | | Guest I/O page table | | | '---------------------------' .----------------/ | PASID Entry |--- PASID cache flush --+ '-------------' | | | V | | I/O page table pointer in GPA '-------------' Guest ------| Shadow |---------------------------|-------- v v v Host .-------------. .------------------------. | pIOMMU | | FS for GIOVA->GPA | | | '------------------------' .----------------/ | | PASID Entry | V (Nested xlate) '----------------\.----------------------------------. | | | SS for GPA->HPA, unmanaged domain| | | '----------------------------------' '-------------' Where: - FS = First stage page tables - SS = Second stage page tables <Intel VT-d Nested translation> This series is based on the first part which was merged [1], this series is to add the cache invalidation interface or the userspace to invalidate cache after modifying the stage-1 page table. This includes both the iommufd changes and the VT-d driver changes. Complete code can be found in [2], QEMU could can be found in [3]. At last, this is a team work together with Nicolin Chen, Lu Baolu. Thanks them for the help. ^_^. Look forward to your feedbacks.

The major difference is adding the VT-d related invalidation uapi structures together with the generic data structures in patch 02 of this series. - VT-d driver was refined to report ICE/ITE error from the bottom cache invalidation submit helpers, hence the cache_invalidate_user op could report such errors via the per-entry error field to user. VT-d driver will not stop the invalidation array walking due to the ICE/ITE errors as such errors are defined by VT-d spec, userspace should be able to handle it and let the real user (say Virtual Machine) know about it. But for other errors like invalid uapi data structure configuration, memory copy failure, such errors should stop the array walking as it may have more issues if go on. - Minor fixes per Jason and Kevin's review comments v6: https://lore.kernel.org/linux-iommu/20231117130717.19875-1-yi.l.liu@intel.c… - No much change, just rebase on top of 6.7-rc1 as part 1/2 is merged v5: https://lore.kernel.org/linux-iommu/20231020092426.13907-1-yi.l.liu@intel.c… - Split the iommufd nesting series into two parts of alloc_user and invalidation (Jason) - Split IOMMUFD_OBJ_HW_PAGETABLE to IOMMUFD_OBJ_HWPT_PAGING/_NESTED, and do the same with the structures/alloc()/abort()/destroy().

[RFC PATCH v5 0/4] Introduce mseal()

by jeffxu＠chromium.org

From: Jeff Xu <jeffxu(a)chromium.org> This patchset proposes a new mseal() syscall for the Linux kernel. In a nutshell, mseal() protects the VMAs of a given virtual memory range against modifications, such as changes to their permission bits. Modern CPUs support memory permissions, such as the read/write (RW) and no-execute (NX) bits. Linux has supported NX since the release of kernel version 2.6.8 in August 2004 [1]. The memory permission feature improves the security stance on memory corruption bugs, as an attacker cannot simply write to arbitrary memory and point the code to it. The memory must be marked with the X bit, or else an exception will occur. Internally, the kernel maintains the memory permissions in a data structure called VMA (vm_area_struct). mseal() additionally protects the VMA itself against modifications of the selected seal type. Memory sealing is useful to mitigate memory corruption issues where a corrupted pointer is passed to a memory management system. For example, such an attacker primitive can break control-flow integrity guarantees since read-only memory that is supposed to be trusted can become writable or .text pages can get remapped. Memory sealing can automatically be applied by the runtime loader to seal .text and .rodata pages and applications can additionally seal security critical data at runtime. A similar feature already exists in the XNU kernel with the VM_FLAGS_PERMANENT [3] flag and on OpenBSD with the mimmutable syscall [4]. Also, Chrome wants to adopt this feature for their CFI work [2] and this patchset has been designed to be compatible with the Chrome use case. Two system calls are involved in sealing the map: mmap() and mseal(). The new mseal() is an syscall on 64 bit CPU, and with following signature: int mseal(void addr, size_t len, unsigned long flags) addr/len: memory range. flags: reserved. mseal() blocks following operations for the given memory range. 1> Unmapping, moving to another location, and shrinking the size, via munmap() and mremap(), can leave an empty space, therefore can be replaced with a VMA with a new set of attributes. 2> Moving or expanding a different VMA into the current location, via mremap(). 3> Modifying a VMA via mmap(MAP_FIXED). 4> Size expansion, via mremap(), does not appear to pose any specific risks to sealed VMAs. It is included anyway because the use case is unclear. In any case, users can rely on merging to expand a sealed VMA. 5> mprotect() and pkey_mprotect(). 6> Some destructive madvice() behaviors (e.g. MADV_DONTNEED) for anonymous memory, when users don't have write permission to the memory. Those behaviors can alter region contents by discarding pages, effectively a memset(0) for anonymous memory. In addition: mmap() has two related changes. The PROT_SEAL bit in prot field of mmap(). When present, it marks the map sealed since creation. The MAP_SEALABLE bit in the flags field of mmap(). When present, it marks the map as sealable. A map created without MAP_SEALABLE will not support sealing, i.e. mseal() will fail. Applications that don't care about sealing will expect their behavior unchanged. For those that need sealing support, opt-in by adding MAP_SEALABLE in mmap(). The idea that inspired this patch comes from Stephen Röttger’s work in V8 CFI [5]. Chrome browser in ChromeOS will be the first user of this API. Indeed, the Chrome browser has very specific requirements for sealing, which are distinct from those of most applications. For example, in the case of libc, sealing is only applied to read-only (RO) or read-execute (RX) memory segments (such as .text and .RELRO) to prevent them from becoming writable, the lifetime of those mappings are tied to the lifetime of the process. Chrome wants to seal two large address space reservations that are managed by different allocators. The memory is mapped RW- and RWX respectively but write access to it is restricted using pkeys (or in the future ARM permission overlay extensions). The lifetime of those mappings are not tied to the lifetime of the process, therefore, while the memory is sealed, the allocators still need to free or discard the unused memory. For example, with madvise(DONTNEED). However, always allowing madvise(DONTNEED) on this range poses a security risk. For example if a jump instruction crosses a page boundary and the second page gets discarded, it will overwrite the target bytes with zeros and change the control flow. Checking write-permission before the discard operation allows us to control when the operation is valid. In this case, the madvise will only succeed if the executing thread has PKEY write permissions and PKRU changes are protected in software by control-flow integrity. Although the initial version of this patch series is targeting the Chrome browser as its first user, it became evident during upstream discussions that we would also want to ensure that the patch set eventually is a complete solution for memory sealing and compatible with other use cases. The specific scenario currently in mind is glibc's use case of loading and sealing ELF executables. To this end, Stephen is working on a change to glibc to add sealing support to the dynamic linker, which will seal all non-writable segments at startup. Once this work is completed, all applications will be able to automatically benefit from these new protections. Change history: =============== V5: - fix build issue in mseal-Wire-up-mseal-syscall (Suggested by Linus Torvalds, and Greg KH) - updates on selftest. V4: (Suggested by Linus Torvalds) - new signature: mseal(start,len,flags) - 32 bit is not supported. vm_seal is removed, use vm_flags instead. - single bit in vm_flags for sealed state. - CONFIG_MSEAL kernel config is removed. - single bit of PROT_SEAL in the "Prot" field of mmap(). Other changes: - update selftest (Suggested by Muhammad Usama Anjum) - update documentation. https://lore.kernel.org/all/20240104185138.169307-1-jeffxu@chromium.org/ V3: - Abandon per-syscall approach, (Suggested by Linus Torvalds). - Organize sealing types around their functionality, such as MM_SEAL_BASE, MM_SEAL_PROT_PKEY. - Extend the scope of sealing from calls originated in userspace to both kernel and userspace. (Suggested by Linus Torvalds) - Add seal type support in mmap(). (Suggested by Pedro Falcato) - Add a new sealing type: MM_SEAL_DISCARD_RO_ANON to prevent destructive operations of madvise. (Suggested by Jann Horn and Stephen Röttger) - Make sealed VMAs mergeable. (Suggested by Jann Horn) - Add MAP_SEALABLE to mmap() - Add documentation - mseal.rst https://lore.kernel.org/linux-mm/20231212231706.2680890-2-jeffxu@chromium.o… v2: Use _BITUL to define MM_SEAL_XX type. Use unsigned long for seal type in sys_mseal() and other functions. Remove internal VM_SEAL_XX type and convert_user_seal_type(). Remove MM_ACTION_XX type. Remove caller_origin(ON_BEHALF_OF_XX) and replace with sealing bitmask. Add more comments in code.

[PATCH 1/1] selftests: mm: hugepage-vmemmap fails on 64K page size systems.

by Donet Tom

The kernel sefltest mm/hugepage-vmemmap fails on architectures which has different page size other than 4K. In hugepage-vmemmap page size used is 4k so the pfn calculation will go wrong on systems which has different page size .The length of MAP_HUGETLB memory must be hugepage aligned but in hugepage-vmemmap map length is 2M so this will not get aligned if the system has differnet hugepage size. Added psize() to get the page size and default_huge_page_size() to get the default hugepage size at run time, hugepage-vmemmap test pass on powerpc with 64K page size and x86 with 4K page size. Result on powerpc without patch (page size 64K) *# ./hugepage-vmemmap Returned address is 0x7effff000000 whose pfn is 0 Head page flags (100000000) is invalid check_page_flags: Invalid argument *# Result on powerpc with patch (page size 64K) *# ./hugepage-vmemmap Returned address is 0x7effff000000 whose pfn is 600 *# Result on x86 with patch (page size 4K) *# ./hugepage-vmemmap Returned address is 0x7fc7c2c00000 whose pfn is 1dac00 *# Signed-off-by: Donet Tom <donettom(a)linux.vnet.ibm.com> Reported-by : Geetika Moolchandani (geetika(a)linux.ibm.com) Tested-by : Geetika Moolchandani (geetika(a)linux.ibm.com) --- tools/testing/selftests/mm/hugepage-vmemmap.c | 29 ++++++++++++------- 1 file changed, 18 insertions(+), 11 deletions(-) diff --git a/tools/testing/selftests/mm/hugepage-vmemmap.c b/tools/testing/selftests/mm/hugepage-vmemmap.c index 5b354c209e93..894d28c3dd47 100644 --- a/tools/testing/selftests/mm/hugepage-vmemmap.c +++ b/tools/testing/selftests/mm/hugepage-vmemmap.c @@ -10,10 +10,7 @@ #include <unistd.h> #include <sys/mman.h> #include <fcntl.h> - -#define MAP_LENGTH (2UL * 1024 * 1024) - -#define PAGE_SIZE 4096 +#include "vm_util.h" #define PAGE_COMPOUND_HEAD (1UL << 15) #define PAGE_COMPOUND_TAIL (1UL << 16) @@ -39,6 +36,9 @@ #define MAP_FLAGS (MAP_PRIVATE | MAP_ANONYMOUS | MAP_HUGETLB) #endif +static size_t pagesize; +static size_t maplength; + static void write_bytes(char *addr, size_t length) { unsigned long i; @@ -56,7 +56,7 @@ static unsigned long virt_to_pfn(void *addr) if (fd < 0) return -1UL; - lseek(fd, (unsigned long)addr / PAGE_SIZE * sizeof(pagemap), SEEK_SET); + lseek(fd, (unsigned long)addr / pagesize * sizeof(pagemap), SEEK_SET); read(fd, &pagemap, sizeof(pagemap)); close(fd); @@ -86,7 +86,7 @@ static int check_page_flags(unsigned long pfn) * this also verifies kernel has correctly set the fake page_head to tail * while hugetlb_free_vmemmap is enabled. */ - for (i = 1; i < MAP_LENGTH / PAGE_SIZE; i++) { + for (i = 1; i < maplength / pagesize; i++) { read(fd, &pageflags, sizeof(pageflags)); if ((pageflags & TAIL_PAGE_FLAGS) != TAIL_PAGE_FLAGS || (pageflags & HEAD_PAGE_FLAGS) == HEAD_PAGE_FLAGS) { @@ -106,18 +106,25 @@ int main(int argc, char **argv) void *addr; unsigned long pfn; - addr = mmap(MAP_ADDR, MAP_LENGTH, PROT_READ | PROT_WRITE, MAP_FLAGS, -1, 0); + pagesize = psize(); + maplength = default_huge_page_size(); + if (!maplength) { + printf("Unable to determine huge page size\n"); + exit(1); + } + + addr = mmap(MAP_ADDR, maplength, PROT_READ | PROT_WRITE, MAP_FLAGS, -1, 0); if (addr == MAP_FAILED) { perror("mmap"); exit(1); } /* Trigger allocation of HugeTLB page. */ - write_bytes(addr, MAP_LENGTH); + write_bytes(addr, maplength); pfn = virt_to_pfn(addr); if (pfn == -1UL) { - munmap(addr, MAP_LENGTH); + munmap(addr, maplength); perror("virt_to_pfn"); exit(1); } @@ -125,13 +132,13 @@ int main(int argc, char **argv) printf("Returned address is %p whose pfn is %lx\n", addr, pfn); if (check_page_flags(pfn) < 0) { - munmap(addr, MAP_LENGTH); + munmap(addr, maplength); perror("check_page_flags"); exit(1); } /* munmap() length of MAP_HUGETLB memory must be hugepage aligned */ - if (munmap(addr, MAP_LENGTH)) { + if (munmap(addr, maplength)) { perror("munmap"); exit(1); } -- 2.43.0

[GIT PULL] KUnit next update for Linux 6.8-rc1

by Shuah Khan

Hi Linus, Please pull the following KUnit next update for Linux 6.8-rc1. This KUnit update for Linux 6.8-rc1 consists of: - a new feature that adds APIs for managing devices introducing a set of helper functions which allow devices (internally a struct kunit_device) to be created and managed by KUnit. These devices will be automatically unregistered on test exit. These helpers can either use a user-provided struct device_driver, or have one automatically created and managed by KUnit. In both cases, the device lives on a new kunit_bus. - changes to switch drm/tests to use kunit devices - several fixes and enhancements to attribute feature - changes to reorganize deferred action function introducing KUNIT_DEFINE_ACTION_WRAPPER - new feature adds ability to run tests after boot using debugfs - fixes and enhancements to string-stream-test: - parse ERR_PTR in string_stream_destroy() - unchecked dereference in bug fix in debugfs_print_results() - handling errors from alloc_string_stream() - NULL-dereference bug fix in kunit_init_suite() diff is attached. thanks, -- Shuah ---------------------------------------------------------------- The following changes since commit ceb6a6f023fd3e8b07761ed900352ef574010bcb: Linux 6.7-rc6 (2023-12-17 15:19:28 -0800) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest tags/linux_kselftest-kunit-6.8-rc1 for you to fetch changes up to 539e582a375dedee95a4fa9ca3f37cdb25c441ec: kunit: Fix some comments which were mistakenly kerneldoc (2024-01-03 09:10:37 -0700) ---------------------------------------------------------------- linux_kselftest-kunit-6.8-rc1 This KUnit update for Linux 6.8-rc1 consists of: - a new feature that adds APIs for managing devices introducing a set of helper functions which allow devices (internally a struct kunit_device) to be created and managed by KUnit.

[PATCH RESEND v4 0/3] livepatch: Move modules to selftests and add a new test

by Marcos Paulo de Souza

Changes in v4: * Documented how to compile the livepatch selftests without running the tests (Joe) * Removed the mention to lib/livepatch on MAINTAINERS file, reported by checkpatch. Changes in v3: * Rebased on top of v6.6-rc5 * The commits messages were improved (Thanks Petr!) * Created TEST_GEN_MODS_DIR variable to point to a directly that contains kernel modules, and adapt selftests to build it before running the test. * Moved test_klp-call_getpid out of test_programs, since the gen_tar would just copy the generated test programs to the livepatches dir, and so scripts relying on test_programs/test_klp-call_getpid will fail. * Added a module_param for klp_pids, describing it's usage. * Simplified the call_getpid program to ignore the return of getpid syscall, since we only want to make sure the process transitions correctly to the patched stated * The test-syscall.sh not prints a log message showing the number of remaining processes to transition into to livepatched state, and check_output expects it to be 0. * Added MODULE_AUTHOR and MODULE_DESCRIPTION to test_klp_syscall.c - Link to v3: https://lore.kernel.org/r/20231031-send-lp-kselftests-v3-0-2b1655c2605f@sus… - Link to v2: https://lore.kernel.org/linux-kselftest/20220630141226.2802-1-mpdesouza@sus… This patchset moves the current kernel testing livepatch modules from lib/livepatches to tools/testing/selftest/livepatch/test_modules, and compiles them as out-of-tree modules before testing. There is also a new test being added. This new test exercises multiple processes calling a syscall, while a livepatch patched the syscall. Why this move is an improvement: * The modules are now compiled as out-of-tree modules against the current running kernel, making them capable of being tested on different systems with newer or older kernels. * Such approach now needs kernel-devel package to be installed, since they are out-of-tree modules. These can be generated by running "make rpm-pkg" in the kernel source. What needs to be solved: * Currently gen_tar only packages the resulting binaries of the tests, and not the sources. For the current approach, the newly added modules would be compiled and then packaged. It works when testing on a system with the same kernel version. But it will fail when running on a machine with different kernel version, since module was compiled against the kernel currently running. This is not a new problem, just aligning the expectations. For the current approach to be truly system agnostic gen_tar would need to include the module and program sources to be compiled in the target systems. Thanks in advance!

[PATCH v2 0/4] kselftest: alsa: Fix a couple of format specifiers and function parameters

by Mirsad Todorovac

Minor fixes of compiler warnings and one bug in the number of parameters which would not crash the test but it is better fixed for correctness sake. As the general climate in the Linux kernel community is to fix all compiler warnings, this could be on the right track, even if only in the testing suite. Changelog: v1 -> v2: - Compared to v1, commit subject lines have been adjusted to reflect the style of the subsystem, as suggested by Mark. - 1/4 was already acked and unchanged (adjusted the subject line as suggested) (code unchanged) - 2/4 was acked with suggestion to adjust the subject line (done).

[PATCH v3] kunit: run test suites only after module initialization completes

by Marco Pagani

Commit 2810c1e99867 ("kunit: Fix wild-memory-access bug in kunit_free_suite_set()") fixed a wild-memory-access bug that could have happened during the loading phase of test suites built and executed as loadable modules. However, it also introduced a problematic side effect that causes test suites modules to crash when they attempt to register fake devices. When a module is loaded, it traverses the MODULE_STATE_UNFORMED and MODULE_STATE_COMING states before reaching the normal operating state MODULE_STATE_LIVE. Finally, when the module is removed, it moves to MODULE_STATE_GOING before being released. However, if the loading function load_module() fails between complete_formation() and do_init_module(), the module goes directly from MODULE_STATE_COMING to MODULE_STATE_GOING without passing through MODULE_STATE_LIVE. This behavior was causing kunit_module_exit() to be called without having first executed kunit_module_init(). Since kunit_module_exit() is responsible for freeing the memory allocated by kunit_module_init() through kunit_filter_suites(), this behavior was resulting in a wild-memory-access bug. Commit 2810c1e99867 ("kunit: Fix wild-memory-access bug in kunit_free_suite_set()") fixed this issue by running the tests when the module is still in MODULE_STATE_COMING. However, modules in that state are not fully initialized, lacking sysfs kobjects. Therefore, if a test module attempts to register a fake device, it will inevitably crash. This patch proposes a different approach to fix the original wild-memory-access bug while restoring the normal module execution flow by making kunit_module_exit() able to detect if kunit_module_init() has previously initialized the tests suite set. In this way, test modules can once again register fake devices without crashing. This behavior is achieved by checking whether mod->kunit_suites is a virtual or direct mapping address. If it is a virtual address, then kunit_module_init() has allocated the suite_set in kunit_filter_suites() using kmalloc_array(). On the contrary, if mod->kunit_suites is still pointing to the original address that was set when looking up the .kunit_test_suites section of the module, then the loading phase has failed and there's no memory to be freed. v3: - add a comment to clarify why the start address is checked v2: - add include <linux/mm.h> Fixes: 2810c1e99867 ("kunit: Fix wild-memory-access bug in kunit_free_suite_set()") Tested-by: Richard Fitzgerald <rf(a)opensource.cirrus.com> Reviewed-by: Javier Martinez Canillas <javierm(a)redhat.com> Signed-off-by: Marco Pagani <marpagan(a)redhat.com> --- lib/kunit/test.c | 14 +++++++++++--- 1 file changed, 11 insertions(+), 3 deletions(-) diff --git a/lib/kunit/test.c b/lib/kunit/test.c index 7aceb07a1af9..3263e0d5e0f6 100644 --- a/lib/kunit/test.c +++ b/lib/kunit/test.c @@ -16,6 +16,7 @@ #include <linux/panic.h> #include <linux/sched/debug.h> #include <linux/sched.h> +#include <linux/mm.h> #include "debugfs.h" #include "hooks-impl.h" @@ -775,12 +776,19 @@ static void kunit_module_exit(struct module *mod) }; const char *action = kunit_action(); + /* + * Check if the start address is a valid virtual address to detect + * if the module load sequence has failed and the suite set has not + * been initialized and filtered. + */ + if (!suite_set.start || !virt_addr_valid(suite_set.start)) + return; + if (!action) __kunit_test_suites_exit(mod->kunit_suites, mod->num_kunit_suites); - if (suite_set.start) - kunit_free_suite_set(suite_set); + kunit_free_suite_set(suite_set); } static int kunit_module_notify(struct notifier_block *nb, unsigned long val, @@ -790,12 +798,12 @@ static int kunit_module_notify(struct notifier_block *nb, unsigned long val, switch (val) { case MODULE_STATE_LIVE: + kunit_module_init(mod); break; case MODULE_STATE_GOING: kunit_module_exit(mod); break; case MODULE_STATE_COMING: - kunit_module_init(mod); break; case MODULE_STATE_UNFORMED: break; base-commit: 33cc938e65a98f1d29d0a18403dbbee050dcad9a -- 2.43.0

[PATCH v7 0/3] Add Intel VT-d nested translation (part 2/2)

by Yi Liu

This is the second part to add Intel VT-d nested translation based on IOMMUFD nesting infrastructure. As the iommufd nesting infrastructure series [1], iommu core supports new ops to invalidate the cache after the modifictions in stage-1 page table. So far, the cache invalidation data is vendor specific, the data_type (IOMMU_HWPT_DATA_VTD_S1) defined for the vendor specific HWPT allocation is reused in the cache invalidation path. User should provide the correct data_type that suit with the type used in HWPT allocation. IOMMU_HWPT_INVALIDATE iotcl returns an error in @out_driver_error_code. However Intel VT-d does not define error code so far, so it's not easy to pre-define it in iommufd neither. As a result, this field should just be ignored on VT-d platform. Complete code can be found in [2], corresponding QEMU could can be found in [3].

[PATCH v6 0/6] iommufd: Add nesting infrastructure (part 2/2)

by Yi Liu

Nested translation is a hardware feature that is supported by many modern IOMMU hardwares. It has two stages (stage-1, stage-2) address translation to get access to the physical address. stage-1 translation table is owned by userspace (e.g. by a guest OS), while stage-2 is owned by kernel. Changes to stage-1 translation table should be followed by an IOTLB invalidation. Take Intel VT-d as an example, the stage-1 translation table is I/O page table. As the below diagram shows, guest I/O page table pointer in GPA (guest physical address) is passed to host and be used to perform the stage-1 address translation. Along with it, modifications to present mappings in the guest I/O page table should be followed with an IOTLB invalidation. .-------------. .---------------------------. | vIOMMU | | Guest I/O page table | | | '---------------------------' .----------------/ | PASID Entry |--- PASID cache flush --+ '-------------' | | | V | | I/O page table pointer in GPA '-------------' Guest ------| Shadow |---------------------------|-------- v v v Host .-------------. .------------------------. | pIOMMU | | FS for GIOVA->GPA | | | '------------------------' .----------------/ | | PASID Entry | V (Nested xlate) '----------------\.----------------------------------. | | | SS for GPA->HPA, unmanaged domain| | | '----------------------------------' '-------------' Where: - FS = First stage page tables - SS = Second stage page tables <Intel VT-d Nested translation> This series adds the cache invalidation path for the userspace to invalidate cache after modifying the stage-1 page table. This is based on the first part of nesting [1] Complete code can be found in [2], QEMU could can be found in [3]. At last, this is a team work together with Nicolin Chen, Lu Baolu. Thanks them for the help. ^_^. Look forward to your feedbacks.

[PATCH bpf-next v2 0/3] Annotate kfuncs in .BTF_ids section

by Daniel Xu

=== Description === This is a bpf-treewide change that annotates all kfuncs as such inside .BTF_ids. This annotation eventually allows us to automatically generate kfunc prototypes from bpftool.

[PATCH net-next] selftests: forwarding: Avoid failures to source net/lib.sh

by Benjamin Poirier

The expression "source ../lib.sh" added to net/forwarding/lib.sh in commit 25ae948b4478 ("selftests/net: add lib.sh") does not work for tests outside net/forwarding which source net/forwarding/lib.sh (1). It also does not work in some cases where only a subset of tests are exported (2). Avoid the problems mentioned above by replacing the faulty expression with a copy of the content from net/lib.sh which is used by files under net/forwarding. A more thorough solution which avoids duplicating content between net/lib.sh and net/forwarding/lib.sh has been posted here: https://lore.kernel.org/netdev/20231222135836.992841-1-bpoirier@nvidia.com/ The approach in the current patch is a stopgap solution to avoid submitting large changes at the eleventh hour of this development cycle. Example of problem 1) tools/testing/selftests/drivers/net/bonding$ ./dev_addr_lists.sh ./net_forwarding_lib.sh: line 41: ../lib.sh: No such file or directory TEST: bonding cleanup mode active-backup [ OK ] TEST: bonding cleanup mode 802.3ad [ OK ] TEST: bonding LACPDU multicast address to slave (from bond down) [ OK ] TEST: bonding LACPDU multicast address to slave (from bond up) [ OK ] An error message is printed but since the test does not use functions from net/lib.sh, the test results are not affected. Example of problem 2) tools/testing/selftests$ make install TARGETS="net/forwarding" tools/testing/selftests$ cd kselftest_install/net/forwarding/ tools/testing/selftests/kselftest_install/net/forwarding$ ./pedit_ip.sh veth{0..3} lib.sh: line 41: ../lib.sh: No such file or directory TEST: ping [ OK ] TEST: ping6 [ OK ] ./pedit_ip.sh: line 135: busywait: command not found TEST: dev veth1 ingress pedit ip src set 198.51.100.1 [FAIL] Expected to get 10 packets, but got . ./pedit_ip.sh: line 135: busywait: command not found TEST: dev veth2 egress pedit ip src set 198.51.100.1 [FAIL] Expected to get 10 packets, but got . ./pedit_ip.sh: line 135: busywait: command not found TEST: dev veth1 ingress pedit ip dst set 198.51.100.1 [FAIL] Expected to get 10 packets, but got . ./pedit_ip.sh: line 135: busywait: command not found TEST: dev veth2 egress pedit ip dst set 198.51.100.1 [FAIL] Expected to get 10 packets, but got . ./pedit_ip.sh: line 135: busywait: command not found TEST: dev veth1 ingress pedit ip6 src set 2001:db8:2::1 [FAIL] Expected to get 10 packets, but got . ./pedit_ip.sh: line 135: busywait: command not found TEST: dev veth2 egress pedit ip6 src set 2001:db8:2::1 [FAIL] Expected to get 10 packets, but got . ./pedit_ip.sh: line 135: busywait: command not found TEST: dev veth1 ingress pedit ip6 dst set 2001:db8:2::1 [FAIL] Expected to get 10 packets, but got . ./pedit_ip.sh: line 135: busywait: command not found TEST: dev veth2 egress pedit ip6 dst set 2001:db8:2::1 [FAIL] Expected to get 10 packets, but got .

Wdyt? _6_offset_to_skb_data is for sure not redundant. I don't test a partial fill from the most significant bits in my patch 13. u16_offset_to_skb_data is somewhat similar to fill_32bit_after_spill_64bit, but they aren't exactly the same: the former spills (u32)20 and fills (u16)20 (the same value), while my test spills (u64)0xXXXXXXXX00000000 and fills (u32)0 (the most significant bits are stripped). Maybe u16_offset_to_skb_data is redundant, but more coverage is better than less coverage, isn't it? > > diff --git a/tools/testing/selftests/bpf/progs/verifier_spill_fill.c b/tools/testing/selftests/bpf/progs/verifier_spill_fill.c > > index 809a09732168..de03e72e07a9 100644 > > --- a/tools/testing/selftests/bpf/progs/verifier_spill_fill.c > > +++ b/tools/testing/selftests/bpf/progs/verifier_spill_fill.c > > @@ -217,7 +217,7 @@ __naked void uninit_u32_from_the_stack(void) > > > > SEC("tc") > > __description("Spill a u32 const scalar.

[PATCH net-next v3 0/3] net: gro: reduce extension header parsing overhead

by Richard Gobert

This series attempts to reduce the parsing overhead of IPv6 extension headers in GRO and GSO, by removing extension header specific code and enabling the frag0 fast path. The following changes were made: - Removed some unnecessary HBH conditionals by adding HBH offload to inet6_offloads - Added a utility function to support frag0 fast path in ipv6_gro_receive - Added selftests for IPv6 packets with extension headers in GRO Richard v2 -> v3: - Removed previously added IPv6 extension header length constant and using sizeof(*opth) instead. - Removed unnecessary conditional in gro selftest framework - v2: https://lore.kernel.org/netdev/127b8199-1cd4-42d7-9b2b-875abaad93fe@gmail.c… v1 -> v2: - Added a minimum IPv6 extension header length constant to make code self documenting. - Added new selftest which checks that packets with different extension header payloads do not coalesce. - Added more info in the second commit message regarding the code changes. - v1: https://lore.kernel.org/netdev/f4eff69d-3917-4c42-8c6b-d09597ac4437@gmail.c… Richard Gobert (3): net: gso: add HBH extension header offload support net: gro: parse ipv6 ext headers without frag0 invalidation selftests/net: fix GRO coalesce test and add ext header coalesce tests net/ipv6/exthdrs_offload.c | 11 ++++ net/ipv6/ip6_offload.c | 76 +++++++++++++++++-------- tools/testing/selftests/net/gro.c | 93 +++++++++++++++++++++++++++++-- 3 files changed, 150 insertions(+), 30 deletions(-) -- 2.36.1

[PATCH v4 8/8] selftests/pcie_bwctrl: Create selftests

by Ilpo Järvinen

Create selftests for PCIe BW control through the PCIe cooling device sysfs interface. First, the BW control selftest finds the PCIe Port to test with. By default, the PCIe Port with the highest Link Speed is selected but another PCIe Port can be provided with -d parameter. The actual test steps the cur_state of the cooling device one-by-one from max_state to what the cur_state was initially. The speed change is confirmed by observing the current_link_speed for the corresponding PCIe Port.

[PATCH bpf-next 0/2] Annotate kfuncs in .BTF_ids section

by Daniel Xu

This is a bpf-treewide change that annotates all kfuncs as such inside .BTF_ids. This annotation eventually allows us to automatically generate kfunc prototypes from bpftool. We store this metadata inside a yet-unused flags field inside struct btf_id_set8 (thanks Kumar!). pahole will be taught where to look. More details about the full chain of events are available in commit 2's description.

[PATCHv3 net-next 3/3] selftest/ptp: extend test to include ptp_gettimex64any()

by Mahesh Bandewar

Update testptp.c to exercise the new ptp method gettimex64any(). When only -x option is given the PTP_SYS_OFFSET_EXTENDED or gettimex64() method is exercised while presence of -x with -y will exercise PTP_SYS_OFFSET_ANY or gettimex64any() method. -y option is to choose the timebase from available options of real, mono, or raw.

[RFC PATCH v3 0/3] Add test to verify probe of devices from discoverable busses

by Nícolas F. R. A. Prado

Hi, for this v3 I changed the approach for identifying devices in a stable way from the match fields back to the hardware topology (used in v1). The match fields were proposed as a way to avoid the possible issue of PCI topology being reconfigured, but that wasn't observed on any real system so far. However using match fields does allow for a real issue if an external device similar to an internal one is connected to the system, which results in a change of the match count and therefore a test failure. So using the HW topology was chosen as the most reliable approach. The per-platform device description file now uses YAML following a suggestion from Chris Obbard, and the test script was re-written in python to handle the new YAML format. A second sample board file is also now included for an x86 platform, which contains an USB controller behind a PCI controller, which wasn't possible to describe in v1. Thanks, Nícolas v2: https://lore.kernel.org/all/20231127233558.868365-1-nfraprado@collabora.com v1: https://lore.kernel.org/all/20231024211818.365844-1-nfraprado@collabora.com Original cover letter: This is part of an effort to improve detection of regressions impacting device probe on all platforms. The recently merged DT kselftest [3] detects probe issues for all devices described statically in the DT. That leaves out devices discovered at run-time from discoverable busses. This is where this test comes in. All of the devices that are connected through discoverable busses (ie USB and PCI), and which are internal and therefore always present, can be described in a per-platform file so they can be checked for. The test will check that the device has been instantiated and bound to a driver. Patch 1 introduces the test. Patch 2 and 3 add the device definitions for the google,spherion machine (Acer Chromebook 514) and XPS 13 as examples.

[PATCH] kunit: Protect string comparisons against NULL

by Richard Fitzgerald

Add NULL checks to KUNIT_BINARY_STR_ASSERTION() so that it will fail cleanly if either pointer is NULL, instead of causing a NULL pointer dereference in the strcmp(). A test failure could be that a string is unexpectedly NULL. This could be trapped by KUNIT_ASSERT_NOT_NULL() but that would terminate the test at that point. It's preferable that the KUNIT_EXPECT_STR*() macros can handle NULL pointers as a failure.

[PATCH v2 net-next] selftests/net: change shebang to bash to support "source"

by Yujie Liu

The patch set [1] added a general lib.sh in net selftests, and converted several test scripts to source the lib.sh. unicast_extensions.sh (converted in [1]) and pmtu.sh (converted in [2]) have a /bin/sh shebang which may point to various shells in different distributions, but "source" is only available in some of them. For example, "source" is a built-it function in bash, but it cannot be used in dash. Refer to other scripts that were converted together, simply change the shebang to bash to fix the following issues when the default /bin/sh points to other shells. # selftests: net: unicast_extensions.sh # ./unicast_extensions.sh: 31: source: not found # ########################################################################### # Unicast address extensions tests (behavior of reserved IPv4 addresses) # ########################################################################### # TEST: assign and ping within 240/4 (1 of 2) (is allowed) [FAIL] # TEST: assign and ping within 240/4 (2 of 2) (is allowed) [FAIL] # TEST: assign and ping within 0/8 (1 of 2) (is allowed) [FAIL] # TEST: assign and ping within 0/8 (2 of 2) (is allowed) [FAIL] # TEST: assign and ping inside 255.255/16 (is allowed) [FAIL] # TEST: assign and ping inside 255.255.255/24 (is allowed) [FAIL] # TEST: route between 240.5.6/24 and 255.1.2/24 (is allowed) [FAIL] # TEST: route between 0.200/16 and 245.99/16 (is allowed) [FAIL] # TEST: assign and ping lowest address (/24) [FAIL] # TEST: assign and ping lowest address (/26) [FAIL] # TEST: routing using lowest address [FAIL] # TEST: assigning 0.0.0.0 (is forbidden) [ OK ] # TEST: assigning 255.255.255.255 (is forbidden) [ OK ] # TEST: assign and ping inside 127/8 (is forbidden) [ OK ] # TEST: assign and ping class D address (is forbidden) [ OK ] # TEST: routing using class D (is forbidden) [ OK ] # TEST: routing using 127/8 (is forbidden) [ OK ] not ok 51 selftests: net: unicast_extensions.sh # exit=1 v1 -> v2: - Fix pmtu.sh which has the same issue as unicast_extensions.sh, suggested by Hangbin - Change the style of the "source" line to be consistent with other tests, suggested by Hangbin Link: https://lore.kernel.org/all/20231202020110.362433-1-liuhangbin@gmail.com/ [1] Link: https://lore.kernel.org/all/20231219094856.1740079-1-liuhangbin@gmail.com/ [2] Reported-by: kernel test robot <oliver.sang(a)intel.com> Signed-off-by: Yujie Liu <yujie.liu(a)intel.com> --- tools/testing/selftests/net/pmtu.sh | 4 ++-- tools/testing/selftests/net/unicast_extensions.sh | 4 ++-- 2 files changed, 4 insertions(+), 4 deletions(-) diff --git a/tools/testing/selftests/net/pmtu.sh b/tools/testing/selftests/net/pmtu.sh index 175d3d1d773b..f10879788f61 100755 --- a/tools/testing/selftests/net/pmtu.sh +++ b/tools/testing/selftests/net/pmtu.sh @@ -1,4 +1,4 @@ -#!/bin/sh +#!/bin/bash # SPDX-License-Identifier: GPL-2.0 # # Check that route PMTU values match expectations, and that initial device MTU @@ -198,7 +198,7 @@ # - pmtu_ipv6_route_change # Same as above but with IPv6 -source ./lib.sh +source lib.sh PAUSE_ON_FAIL=no VERBOSE=0 diff --git a/tools/testing/selftests/net/unicast_extensions.sh b/tools/testing/selftests/net/unicast_extensions.sh index b7a2cb9e7477..f52aa5f7da52 100755 --- a/tools/testing/selftests/net/unicast_extensions.sh +++ b/tools/testing/selftests/net/unicast_extensions.sh @@ -1,4 +1,4 @@ -#!/bin/sh +#!/bin/bash # SPDX-License-Identifier: GPL-2.0 # # By Seth Schoen (c) 2021, for the IPv4 Unicast Extensions Project @@ -28,7 +28,7 @@ # These tests provide an easy way to flip the expected result of any # of these behaviors for testing kernel patches that change them. -source ./lib.sh +source lib.sh # nettest can be run from PATH or from same directory as this selftest if ! which nettest >/dev/null; then base-commit: cd4d7263d58ab98fd4dee876776e4da6c328faa3 -- 2.34.1

[PATCH v10 00/10] Add iommufd nesting (part 2/2)

by Yi Liu

Nested translation is a hardware feature that is supported by many modern IOMMU hardwares. It has two stages (stage-1, stage-2) address translation to get access to the physical address. stage-1 translation table is owned by userspace (e.g. by a guest OS), while stage-2 is owned by kernel. Changes to stage-1 translation table should be followed by an IOTLB invalidation. Take Intel VT-d as an example, the stage-1 translation table is I/O page table. As the below diagram shows, guest I/O page table pointer in GPA (guest physical address) is passed to host and be used to perform the stage-1 address translation. Along with it, modifications to present mappings in the guest I/O page table should be followed with an IOTLB invalidation. .-------------. .---------------------------. | vIOMMU | | Guest I/O page table | | | '---------------------------' .----------------/ | PASID Entry |--- PASID cache flush --+ '-------------' | | | V | | I/O page table pointer in GPA '-------------' Guest ------| Shadow |---------------------------|-------- v v v Host .-------------. .------------------------. | pIOMMU | | FS for GIOVA->GPA | | | '------------------------' .----------------/ | | PASID Entry | V (Nested xlate) '----------------\.----------------------------------. | | | SS for GPA->HPA, unmanaged domain| | | '----------------------------------' '-------------' Where: - FS = First stage page tables - SS = Second stage page tables <Intel VT-d Nested translation> This series is based on the first part which was merged [1], this series is to add the cache invalidation interface or the userspace to invalidate cache after modifying the stage-1 page table. This includes both the iommufd changes and the VT-d driver changes. Complete code can be found in [2], QEMU could can be found in [3]. At last, this is a team work together with Nicolin Chen, Lu Baolu. Thanks them for the help. ^_^. Look forward to your feedbacks. [1] https://lore.kernel.org/linux-iommu/20231026044216.64964-1-yi.l.liu@intel.c… - merged [2] https://github.com/yiliu1765/iommufd/tree/iommufd_nesting [3] https://github.com/yiliu1765/qemu/tree/zhenzhong/wip/iommufd_nesting_rfcv1 Change log: v10: - Minor tweak to patch 07 (Kevin) - Rebase on top of 6.7-rc8 v9: https://lore.kernel.org/linux-iommu/20231228150629.13149-1-yi.l.liu@intel.c… - Add a test case which sets both IOMMU_TEST_INVALIDATE_FLAG_ALL and IOMMU_TEST_INVALIDATE_FLAG_TRIGGER_ERROR in flags, and expect to succeed and see an 'error'. (Kevin) - Returns -ETIMEOUT in qi_check_fault() if caller is interested with the fault when timeout happens. If not, the qi_submit_sync() will keep retry hence unable to report the error back to user. For now, only the user cache invalidation path has interest on the time out error. So this change only affects the user cache invalidation path. Other path will still hang in qi_submit_sync() when timeout happens. (Kevin) v8: https://lore.kernel.org/linux-iommu/20231227161354.67701-1-yi.l.liu@intel.c… - Pass invalidation hint to the cache invalidation helper in the cache_invalidate_user op path (Kevin) - Move the devTLB invalidation out of info->iommu loop (Kevin, Weijiang) - Clear *fault per restart in qi_submit_sync() to avoid acroos submission error accumulation. (Kevin) - Define the vtd cache invalidation uapi structure in separate patch (Kevin) - Rename inv_error to be hw_error (Kevin) - Rename 'reqs_uptr', 'req_type', 'req_len' and 'req_num' to be 'data_uptr', 'data_type', "entry_len' and 'entry_num" (Kevin) - Allow user to set IOMMU_TEST_INVALIDATE_FLAG_ALL and IOMMU_TEST_INVALIDATE_FLAG_TRIGGER_ERROR in the same time (Kevin) v7: https://lore.kernel.org/linux-iommu/20231221153948.119007-1-yi.l.liu@intel.… - Remove domain->ops->cache_invalidate_user check in hwpt alloc path due to failure in bisect (Baolu) - Remove out_driver_error_code from struct iommu_hwpt_invalidate after discussion in v6. Should expect per-entry error code. - Rework the selftest cache invalidation part to report a per-entry error - Allow user to pass in an empty array to have a try-and-fail mechanism for user to check if a given req_type is supported by the kernel (Jason) - Define a separate enum type for cache invalidation data (Jason) - Fix the IOMMU_HWPT_INVALIDATE to always update the req_num field before returning (Nicolin) - Merge the VT-d nesting part 2/2 https://lore.kernel.org/linux-iommu/20231117131816.24359-1-yi.l.liu@intel.c… into this series to avoid defining empty enum in the middle of the series. The major difference is adding the VT-d related invalidation uapi structures together with the generic data structures in patch 02 of this series. - VT-d driver was refined to report ICE/ITE error from the bottom cache invalidation submit helpers, hence the cache_invalidate_user op could report such errors via the per-entry error field to user. VT-d driver will not stop the invalidation array walking due to the ICE/ITE errors as such errors are defined by VT-d spec, userspace should be able to handle it and let the real user (say Virtual Machine) know about it.

[PATCH bpf-next 0/2] bpf: add csum/ip_summed fields to __sk_buff

by Menglong Dong

For now, we have to call some helpers when we need to update the csum, such as bpf_l4_csum_replace, bpf_l3_csum_replace, etc. These helpers are not inlined, which causes poor performance. In fact, we can define our own csum update functions in BPF program instead of bpf_l3_csum_replace, which is totally inlined and efficient. However, we can't do this for bpf_l4_csum_replace for now, as we can't update skb->csum, which can cause skb->csum invalid in the rx path with CHECKSUM_COMPLETE mode. What's more, we can't use the direct data access and have to use skb_store_bytes() with the BPF_F_RECOMPUTE_CSUM flag in some case, such as modifing the vni in the vxlan header and the underlay udp header has no checksum. In the first patch, we make skb->csum readable and writable, and we make skb->ip_summed readable. For now, for tc only. With these 2 fields, we don't need to call bpf helpers for csum update any more. In the second patch, we add some testcases for the read/write testing for skb->csum and skb->ip_summed. If this series is acceptable, we can define the inlined functions for csum update in libbpf in the next step.

[PATCH v2 1/1] userfaultfd: fix move_pages_pte() splitting folio under RCU read lock

by Suren Baghdasaryan

While testing the split PMD path with lockdep enabled I've got an "Invalid wait context" error caused by split_huge_page_to_list() trying to lock anon_vma->rwsem while inside RCU read section. The issues is due to move_pages_pte() calling split_folio() under RCU read lock. Fix this by unmapping the PTEs and exiting RCU read section before splitting the folio and then retrying. The same retry pattern is used when locking the folio or anon_vma in this function. After splitting the large folio we unlock and release it because after the split the old folio might not be the one that contains the src_addr.

[PATCH v8 00/24] security: Move IMA and EVM to the LSM infrastructure

by Roberto Sassu

From: Roberto Sassu <roberto.sassu(a)huawei.com> IMA and EVM are not effectively LSMs, especially due to the fact that in the past they could not provide a security blob while there is another LSM active. That changed in the recent years, the LSM stacking feature now makes it possible to stack together multiple LSMs, and allows them to provide a security blob for most kernel objects. While the LSM stacking feature has some limitations being worked out, it is already suitable to make IMA and EVM as LSMs. The main purpose of this patch set is to remove IMA and EVM function calls, hardcoded in the LSM infrastructure and other places in the kernel, and to register them as LSM hook implementations, so that those functions are called by the LSM infrastructure like other regular LSMs. This patch set introduces two new LSMs 'ima' and 'evm', so that functions can be registered to their respective LSM, and removes the 'integrity' LSM. integrity_kernel_module_request() was moved to IMA, since it was related to appraisal. integrity_inode_free() was replaced with ima_inode_free_security() (EVM does not need to free memory). In order to make 'ima' and 'evm' independent LSMs, it was necessary to split integrity metadata used by both IMA and EVM, and to let them manage their own. The special case of the IMA_NEW_FILE flag, managed by IMA and used by EVM, was handled by introducing a new flag in EVM, EVM_NEW_FILE, managed by two additional LSM hooks, evm_post_path_mknod() and evm_file_free(), equivalent to their counterparts ima_post_path_mknod() and ima_file_free(). In addition to splitting metadata, it was decided to embed the full structure into the inode security blob, rather than using a cache of objects and allocating them on demand. This opens for new possibilities, such as improving locking in IMA. Another follow-up change was removing the iint parameter from evm_verifyxattr(), that IMA used to pass integrity metadata to EVM. After splitting metadata, and aligning EVM_NEW_FILE with IMA_NEW_FILE, this parameter was not necessary anymore. The last part was to ensure that the order of IMA and EVM functions is respected after they become LSMs. Since the order of lsm_info structures in the .lsm_info.init section depends on the order object files containing those structures are passed to the linker of the kernel image, and since IMA is before EVM in the Makefile, that is sufficient to assert that IMA functions are executed before EVM ones. The patch set is organized as follows. Patches 1-9 make IMA and EVM functions suitable to be registered to the LSM infrastructure, by aligning function parameters. Patches 10-18 add new LSM hooks in the same places where IMA and EVM functions are called, if there is no LSM hook already. Patches 19-21 introduce the new standalone LSMs 'ima' and 'evm', and move hardcoded calls to IMA, EVM and integrity functions to those LSMs. Patches 22-23 remove the dependency on the 'integrity' LSM by splitting integrity metadata, so that the 'ima' and 'evm' LSMs can use their own. They also duplicate iint_lockdep_annotate() in ima_main.c, since the mutex field was moved from integrity_iint_cache to ima_iint_cache. Patch 24 finally removes the 'integrity' LSM, since 'ima' and 'evm' are now self-contained and independent. The patch set applies on top of lsm/dev, commit 80b4ff1d2c9b ("selftests: remove the LSM_ID_IMA check in lsm/lsm_list_modules_test"). The linux-integrity/next-integrity-testing at commit f17167bea279 ("ima: Remove EXPERIMENTAL from Kconfig") was merged. Changelog: v7: - Use return instead of goto in __vfs_removexattr_locked() (suggested by Casey) - Clarify in security/integrity/Makefile that the order of 'ima' and 'evm' LSMs depends on the order in which IMA and EVM are compiled - Move integrity_iint_cache flags to ima.h and evm.h in security/ and duplicate IMA_NEW_FILE to EVM_NEW_FILE - Rename evm_inode_get_iint() to evm_iint_inode() and ima_inode_get_iint() to ima_iint_inode(), check if inode->i_security is NULL, and just return the pointer from the inode security blob - Restore the non-NULL checks after ima_iint_inode() and evm_iint_inode() (suggested by Casey) - Introduce evm_file_free() to clear EVM_NEW_FILE - Remove comment about LSM_ORDER_LAST not guaranteeing the order of 'ima' and 'evm' LSMs - Lock iint->mutex before reading IMA_COLLECTED flag in __ima_inode_hash() and restored ima_policy_flag check - Remove patch about the hardcoded ordering of 'ima' and 'evm' LSMs in security.c - Add missing ima_inode_free_security() to free iint->ima_hash - Add the cases for LSM_ID_IMA and LSM_ID_EVM in lsm_list_modules_test.c - Mention about the change in IMA and EVM post functions for private inodes v6: - See v7 v5: - Rename security_file_pre_free() to security_file_release() and the LSM hook file_pre_free_security to file_release (suggested by Paul) - Move integrity_kernel_module_request() to ima_main.c (renamed to ima_kernel_module_request()) - Split the integrity_iint_cache structure into ima_iint_cache and evm_iint_cache, so that IMA and EVM can use disjoint metadata and reserve space with the LSM infrastructure - Reserve space for the entire ima_iint_cache and evm_iint_cache structures, not just the pointer (suggested by Paul) - Introduce ima_inode_get_iint() and evm_inode_get_iint() to retrieve respectively the ima_iint_cache and evm_iint_cache structure from the security blob - Remove the various non-NULL checks for the ima_iint_cache and evm_iint_cache structures, since the LSM infrastructure ensure that they always exist - Remove the iint parameter from evm_verifyxattr() since IMA and EVM use disjoint integrity metaddata - Introduce the evm_post_path_mknod() to set the IMA_NEW_FILE flag - Register the inode_alloc_security LSM hook in IMA and EVM to initialize the respective integrity metadata structures - Remove the 'integrity' LSM completely and instead make 'ima' and 'evm' proper standalone LSMs - Add the inode parameter to ima_get_verity_digest(), since the inode field is not present in ima_iint_cache - Move iint_lockdep_annotate() to ima_main.c (renamed to ima_iint_lockdep_annotate()) - Remove ima_get_lsm_id() and evm_get_lsm_id(), since IMA and EVM directly register the needed LSM hooks - Enforce 'ima' and 'evm' LSM ordering at LSM infrastructure level v4: - Improve short and long description of security_inode_post_create_tmpfile(), security_inode_post_set_acl(), security_inode_post_remove_acl() and security_file_post_open() (suggested by Mimi) - Improve commit message of 'ima: Move to LSM infrastructure' (suggested by Mimi) v3: - Drop 'ima: Align ima_post_path_mknod() definition with LSM infrastructure' and 'ima: Align ima_post_create_tmpfile() definition with LSM infrastructure', define the new LSM hooks with the same IMA parameters instead (suggested by Mimi) - Do IS_PRIVATE() check in security_path_post_mknod() and security_inode_post_create_tmpfile() on the new inode rather than the parent directory (in the post method it is available) - Don't export ima_file_check() (suggested by Stefan) - Remove redundant check of file mode in ima_post_path_mknod() (suggested by Mimi) - Mention that ima_post_path_mknod() is now conditionally invoked when CONFIG_SECURITY_PATH=y (suggested by Mimi) - Mention when a LSM hook will be introduced in the IMA/EVM alignment patches (suggested by Mimi) - Simplify the commit messages when introducing a new LSM hook - Still keep the 'extern' in the function declaration, until the declaration is removed (suggested by Mimi) - Improve documentation of security_file_pre_free() - Register 'ima' and 'evm' as standalone LSMs (suggested by Paul) - Initialize the 'ima' and 'evm' LSMs from 'integrity', to keep the original ordering of IMA and EVM functions as when they were hardcoded - Return the IMA and EVM LSM IDs to 'integrity' for registration of the integrity-specific hooks - Reserve an xattr slot from the 'evm' LSM instead of 'integrity' - Pass the LSM ID to init_ima_appraise_lsm() v2: - Add description for newly introduced LSM hooks (suggested by Casey) - Clarify in the description of security_file_pre_free() that actions can be performed while the file is still open v1: - Drop 'evm: Complete description of evm_inode_setattr()', 'fs: Fix description of vfs_tmpfile()' and 'security: Introduce LSM_ORDER_LAST', they were sent separately (suggested by Christian Brauner) - Replace dentry with file descriptor parameter for security_inode_post_create_tmpfile() - Introduce mode_stripped and pass it as mode argument to security_path_mknod() and security_path_post_mknod() - Use goto in do_mknodat() and __vfs_removexattr_locked() (suggested by Mimi) - Replace __lsm_ro_after_init with __ro_after_init - Modify short description of security_inode_post_create_tmpfile() and security_inode_post_set_acl() (suggested by Stefan) - Move security_inode_post_setattr() just after security_inode_setattr() (suggested by Mimi) - Modify short description of security_key_post_create_or_update() (suggested by Mimi) - Add back exported functions ima_file_check() and evm_inode_init_security() respectively to ima.h and evm.h (reported by kernel robot) -

[PATCH net-next 0/4] mptcp: add CurrEstab MIB counter

by Matthieu Baerts

This MIB counter is similar to the one of TCP -- CurrEstab -- available in /proc/net/snmp. This is useful to quickly list the number of MPTCP connections without having to iterate over all of them. Patch 1 prepares its support by adding new helper functions: - MPTCP_DEC_STATS(): similar to MPTCP_INC_STATS(), but this time to decrement a counter. - mptcp_set_state(): similar to tcp_set_state(), to change the state of an MPTCP socket, and to inc/decrement the new counter when needed. Patch 2 uses mptcp_set_state() instead of directly calling inet_sk_state_store() to change the state of MPTCP sockets. Patch 3 and 4 validate the new feature in MPTCP "join" and "diag" selftests.

[PATCH v9 00/10] Add iommufd nesting (part 2/2)

by Yi Liu

Nested translation is a hardware feature that is supported by many modern IOMMU hardwares. It has two stages (stage-1, stage-2) address translation to get access to the physical address. stage-1 translation table is owned by userspace (e.g. by a guest OS), while stage-2 is owned by kernel. Changes to stage-1 translation table should be followed by an IOTLB invalidation. Take Intel VT-d as an example, the stage-1 translation table is I/O page table. As the below diagram shows, guest I/O page table pointer in GPA (guest physical address) is passed to host and be used to perform the stage-1 address translation. Along with it, modifications to present mappings in the guest I/O page table should be followed with an IOTLB invalidation. .-------------. .---------------------------. | vIOMMU | | Guest I/O page table | | | '---------------------------' .----------------/ | PASID Entry |--- PASID cache flush --+ '-------------' | | | V | | I/O page table pointer in GPA '-------------' Guest ------| Shadow |---------------------------|-------- v v v Host .-------------. .------------------------. | pIOMMU | | FS for GIOVA->GPA | | | '------------------------' .----------------/ | | PASID Entry | V (Nested xlate) '----------------\.----------------------------------. | | | SS for GPA->HPA, unmanaged domain| | | '----------------------------------' '-------------' Where: - FS = First stage page tables - SS = Second stage page tables <Intel VT-d Nested translation> This series is based on the first part which was merged [1], this series is to add the cache invalidation interface or the userspace to invalidate cache after modifying the stage-1 page table. This includes both the iommufd changes and the VT-d driver changes. Complete code can be found in [2], QEMU could can be found in [3]. At last, this is a team work together with Nicolin Chen, Lu Baolu. Thanks them for the help. ^_^. Look forward to your feedbacks.

(Kevin) - Returns -ETIMEOUT in qi_check_fault() if caller is interested with the fault when timeout happens. If not, the qi_submit_sync() will keep retry hence unable to report the error back to user. For now, only the user cache invalidation path has interest on the time out error. So this change only affects the user cache invalidation path. Other path will still hang in qi_submit_sync() when timeout happens. (Kevin) v8: https://lore.kernel.org/linux-iommu/20231227161354.67701-1-yi.l.liu@intel.c… - Pass invalidation hint to the cache invalidation helper in the cache_invalidate_user op path (Kevin) - Move the devTLB invalidation out of info->iommu loop (Kevin, Weijiang) - Clear *fault per restart in qi_submit_sync() to avoid acroos submission error accumulation. (Kevin) - Define the vtd cache invalidation uapi structure in separate patch (Kevin) - Rename inv_error to be hw_error (Kevin) - Rename 'reqs_uptr', 'req_type', 'req_len' and 'req_num' to be 'data_uptr', 'data_type', "entry_len' and 'entry_num" (Kevin) - Allow user to set IOMMU_TEST_INVALIDATE_FLAG_ALL and IOMMU_TEST_INVALIDATE_FLAG_TRIGGER_ERROR in the same time (Kevin) v7: https://lore.kernel.org/linux-iommu/20231221153948.119007-1-yi.l.liu@intel.… - Remove domain->ops->cache_invalidate_user check in hwpt alloc path due to failure in bisect (Baolu) - Remove out_driver_error_code from struct iommu_hwpt_invalidate after discussion in v6.

The major difference is adding the VT-d related invalidation uapi structures together with the generic data structures in patch 02 of this series. - VT-d driver was refined to report ICE/ITE error from the bottom cache invalidation submit helpers, hence the cache_invalidate_user op could report such errors via the per-entry error field to user. VT-d driver will not stop the invalidation array walking due to the ICE/ITE errors as such errors are defined by VT-d spec, userspace should be able to handle it and let the real user (say Virtual Machine) know about it. But for other errors like invalid uapi data structure configuration, memory copy failure, such errors should stop the array walking as it may have more issues if go on. - Minor fixes per Jason and Kevin's review comments v6: https://lore.kernel.org/linux-iommu/20231117130717.19875-1-yi.l.liu@intel.c… - No much change, just rebase on top of 6.7-rc1 as part 1/2 is merged v5: https://lore.kernel.org/linux-iommu/20231020092426.13907-1-yi.l.liu@intel.c… - Split the iommufd nesting series into two parts of alloc_user and invalidation (Jason) - Split IOMMUFD_OBJ_HW_PAGETABLE to IOMMUFD_OBJ_HWPT_PAGING/_NESTED, and do the same with the structures/alloc()/abort()/destroy().

[PATCH net-next] selftests/net: change the shebang of unicast_extensions.sh to bash

by Yujie Liu

The patch set [1] added a general lib.sh in net selftests, and converted several test scripts to source the lib.sh. The shebang of unicast_extensions.sh is /bin/sh which may point to various shells in different distributions, but "source" is only available in some of them. For example, "source" is a built-it function in bash, but it cannot be used in dash. Refer to other scripts that were converted together, simply change the shebang to bash to suppress the following errors when the default /bin/sh points to other shells. # selftests: net: unicast_extensions.sh # ./unicast_extensions.sh: 31: source: not found # ########################################################################### # Unicast address extensions tests (behavior of reserved IPv4 addresses) # ########################################################################### # TEST: assign and ping within 240/4 (1 of 2) (is allowed) [FAIL] # TEST: assign and ping within 240/4 (2 of 2) (is allowed) [FAIL] # TEST: assign and ping within 0/8 (1 of 2) (is allowed) [FAIL] # TEST: assign and ping within 0/8 (2 of 2) (is allowed) [FAIL] # TEST: assign and ping inside 255.255/16 (is allowed) [FAIL] # TEST: assign and ping inside 255.255.255/24 (is allowed) [FAIL] # TEST: route between 240.5.6/24 and 255.1.2/24 (is allowed) [FAIL] # TEST: route between 0.200/16 and 245.99/16 (is allowed) [FAIL] # TEST: assign and ping lowest address (/24) [FAIL] # TEST: assign and ping lowest address (/26) [FAIL] # TEST: routing using lowest address [FAIL] # TEST: assigning 0.0.0.0 (is forbidden) [ OK ] # TEST: assigning 255.255.255.255 (is forbidden) [ OK ] # TEST: assign and ping inside 127/8 (is forbidden) [ OK ] # TEST: assign and ping class D address (is forbidden) [ OK ] # TEST: routing using class D (is forbidden) [ OK ] # TEST: routing using 127/8 (is forbidden) [ OK ] not ok 51 selftests: net: unicast_extensions.sh # exit=1 Link: https://lore.kernel.org/all/20231202020110.362433-1-liuhangbin@gmail.com/ [1] Fixes: 0f4765d0b48d ("selftests/net: convert unicast_extensions.sh to run it in unique namespace") Reported-by: kernel test robot <oliver.sang(a)intel.com> Signed-off-by: Yujie Liu <yujie.liu(a)intel.com> --- tools/testing/selftests/net/unicast_extensions.sh | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/testing/selftests/net/unicast_extensions.sh b/tools/testing/selftests/net/unicast_extensions.sh index b7a2cb9e7477..2766990c2b78 100755 --- a/tools/testing/selftests/net/unicast_extensions.sh +++ b/tools/testing/selftests/net/unicast_extensions.sh @@ -1,4 +1,4 @@ -#!/bin/sh +#!/bin/bash # SPDX-License-Identifier: GPL-2.0 # # By Seth Schoen (c) 2021, for the IPv4 Unicast Extensions Project -- 2.34.1

Should expect per-entry error code. - Rework the selftest cache invalidation part to report a per-entry error - Allow user to pass in an empty array to have a try-and-fail mechanism for user to check if a given req_type is supported by the kernel (Jason) - Define a separate enum type for cache invalidation data (Jason) - Fix the IOMMU_HWPT_INVALIDATE to always update the req_num field before returning (Nicolin) - Merge the VT-d nesting part 2/2 https://lore.kernel.org/linux-iommu/20231117131816.24359-1-yi.l.liu@intel.c… into this series to avoid defining empty enum in the middle of the series. The major difference is adding the VT-d related invalidation uapi structures together with the generic data structures in patch 02 of this series. - VT-d driver was refined to report ICE/ITE error from the bottom cache invalidation submit helpers, hence the cache_invalidate_user op could report such errors via the per-entry error field to user. VT-d driver will not stop the invalidation array walking due to the ICE/ITE errors as such errors are defined by VT-d spec, userspace should be able to handle it and let the real user (say Virtual Machine) know about it. But for other errors like invalid uapi data structure configuration, memory copy failure, such errors should stop the array walking as it may have more issues if go on. - Minor fixes per Jason and Kevin's review comments v6: https://lore.kernel.org/linux-iommu/20231117130717.19875-1-yi.l.liu@intel.c… - No much change, just rebase on top of 6.7-rc1 as part 1/2 is merged v5: https://lore.kernel.org/linux-iommu/20231020092426.13907-1-yi.l.liu@intel.c… - Split the iommufd nesting series into two parts of alloc_user and invalidation (Jason) - Split IOMMUFD_OBJ_HW_PAGETABLE to IOMMUFD_OBJ_HWPT_PAGING/_NESTED, and do the same with the structures/alloc()/abort()/destroy(). Reworked the selftest accordingly too. (Jason) - Move hwpt/data_type into struct iommu_user_data from standalone op arguments. (Jason) - Rename hwpt_type to be data_type, the HWPT_TYPE to be HWPT_ALLOC_DATA, _TYPE_DEFAULT to be _ALLOC_DATA_NONE (Jason, Kevin) - Rename iommu_copy_user_data() to iommu_copy_struct_from_user() (Kevin) - Add macro to the iommu_copy_struct_from_user() to calculate min_size (Jason) - Fix two bugs spotted by ZhaoYan v4: https://lore.kernel.org/linux-iommu/20230921075138.124099-1-yi.l.liu@intel.… - Separate HWPT alloc/destroy/abort functions between user-managed HWPTs and kernel-managed HWPTs - Rework invalidate uAPI to be a multi-request array-based design - Add a struct iommu_user_data_array and a helper for driver to sanitize and copy the entry data from user space invalidation array - Add a patch fixing TEST_LENGTH() in selftest program - Drop IOMMU_RESV_IOVA_RANGES patches - Update kdoc and inline comments - Drop the code to add IOMMU_RESV_SW_MSI to kernel-managed HWPT in nested translation, this does not change the rule that resv regions should only be added to the kernel-managed HWPT. The IOMMU_RESV_SW_MSI stuff will be added in later series as it is needed only by SMMU so far. v3: https://lore.kernel.org/linux-iommu/20230724110406.107212-1-yi.l.liu@intel.… - Add new uAPI things in alphabetical order - Pass in "enum iommu_hwpt_type hwpt_type" to op->domain_alloc_user for sanity, replacing the previous op->domain_alloc_user_data_len solution - Return ERR_PTR from domain_alloc_user instead of NULL - Only add IOMMU_RESV_SW_MSI to kernel-managed HWPT in nested translation (Kevin) - Add IOMMU_RESV_IOVA_RANGES to report resv iova ranges to userspace hence userspace is able to exclude the ranges in the stage-1 HWPT (e.g. guest I/O page table). (Kevin) - Add selftest coverage for the new IOMMU_RESV_IOVA_RANGES ioctl - Minor changes per Kevin's inputs v2: https://lore.kernel.org/linux-iommu/20230511143844.22693-1-yi.l.liu@intel.c… - Add union iommu_domain_user_data to include all user data structures to avoid passing void * in kernel APIs. - Add iommu op to return user data length for user domain allocation - Rename struct iommu_hwpt_alloc::data_type to be hwpt_type - Store the invalidation data length in iommu_domain_ops::cache_invalidate_user_data_len - Convert cache_invalidate_user op to be int instead of void - Remove @data_type in struct iommu_hwpt_invalidate - Remove out_hwpt_type_bitmap in struct iommu_hw_info hence drop patch 08 of v1 v1: https://lore.kernel.org/linux-iommu/20230309080910.607396-1-yi.l.liu@intel.… Thanks, Yi Liu Lu Baolu (4): iommu: Add cache_invalidate_user op iommu/vt-d: Allow qi_submit_sync() to return the QI faults iommu/vt-d: Convert pasid based cache invalidation to return QI fault iommu/vt-d: Add iotlb flush for nested domain Nicolin Chen (4): iommu: Add iommu_copy_struct_from_user_array helper iommufd/selftest: Add mock_domain_cache_invalidate_user support iommufd/selftest: Add IOMMU_TEST_OP_MD_CHECK_IOTLB test op iommufd/selftest: Add coverage for IOMMU_HWPT_INVALIDATE ioctl Yi Liu (1): iommufd: Add IOMMU_HWPT_INVALIDATE drivers/iommu/intel/dmar.c | 36 ++-- drivers/iommu/intel/iommu.c | 12 +- drivers/iommu/intel/iommu.h | 8 +- drivers/iommu/intel/irq_remapping.c | 2 +- drivers/iommu/intel/nested.c | 116 ++++++++++++ drivers/iommu/intel/pasid.c | 14 +- drivers/iommu/intel/svm.c | 14 +- drivers/iommu/iommufd/hw_pagetable.c | 36 ++++ drivers/iommu/iommufd/iommufd_private.h | 10 ++ drivers/iommu/iommufd/iommufd_test.h | 39 ++++ drivers/iommu/iommufd/main.c | 3 + drivers/iommu/iommufd/selftest.c | 93 ++++++++++ include/linux/iommu.h | 101 +++++++++++ include/uapi/linux/iommufd.h | 100 +++++++++++ tools/testing/selftests/iommu/iommufd.c | 170 ++++++++++++++++++ tools/testing/selftests/iommu/iommufd_utils.h | 57 ++++++ 16 files changed, 773 insertions(+), 38 deletions(-) -- 2.34.1

[PATCH net-next 0/4] mptcp: cleanup and support more ephemeral ports sockopts

by Matthieu Baerts

Patch 1 is a cleanup one: mptcp_is_tcpsk() helper was modifying sock_ops in some cases which is unexpected with that name. Patch 2 to 4 add support for two socket options: IP_LOCAL_PORT_RANGE and IP_BIND_ADDRESS_NO_PORT. The first one is a preparation patch, the second one adds the support while the last one modifies an existing selftest to validate the new features.

[PATCH bpf-next 00/15] Improvements for tracking scalars in the BPF verifier

by Maxim Mikityanskiy

From: Maxim Mikityanskiy <maxim(a)isovalent.com> The goal of this series is to extend the verifier's capabilities of tracking scalars when they are spilled to stack, especially when the spill or fill is narrowing. It also contains a fix by Eduard for infinite loop detection and a state pruning optimization by Eduard that compensates for a verification complexity regression introduced by tracking unbounded scalars. These improvements reduce the surface of false rejections that I saw while working on Cilium codebase. Patch 1 (Maxim): Fix for an existing test, it will matter later in the series. Patches 2-3 (Eduard): Fixes for false rejections in infinite loop detection that happen in the selftests when my patches are applied. Patches 4-5 (Maxim): Fix the inconsistency of find_equal_scalars that was possible if 32-bit spills were made. Patches 6-11 (Maxim): Support the case when boundary checks are first performed after the register was spilled to the stack. Patches 12-13 (Maxim): Support narrowing fills. Patches 14-15 (Eduard): Optimization for state pruning in stacksafe() to mitigate the verification complexity regression. veristat -e file,prog,states -f '!states_diff<50' -f '!states_pct<10' -f '!states_a<10' -f '!states_b<10' -C ... * Without patch 14: File Program States (A) States (B) States (DIFF) -------------------- ------------ ---------- ---------- ---------------- bpf_xdp.o tail_lb_ipv6 3877 2936 -941 (-24.27%) pyperf180.bpf.o on_event 8422 10456 +2034 (+24.15%) pyperf600.bpf.o on_event 22259 37319 +15060 (+67.66%) pyperf600_iter.bpf.o on_event 400 540 +140 (+35.00%) strobemeta.bpf.o on_event 4702 13435 +8733 (+185.73%) * With patch 14: File Program States (A) States (B) States (DIFF) -------------------- ------------ ---------- ---------- -------------- bpf_xdp.o tail_lb_ipv6 3877 2937 -940 (-24.25%) pyperf600_iter.bpf.o on_event 400 500 +100 (+25.00%) Eduard Zingerman (4): bpf: make infinite loop detection in is_state_visited() exact selftests/bpf: check if imprecise stack spills confuse infinite loop detection bpf: Optimize state pruning for spilled scalars selftests/bpf: states pruning checks for scalar vs STACK_{MISC,ZERO} Maxim Mikityanskiy (11): selftests/bpf: Fix the u64_offset_to_skb_data test bpf: Make bpf_for_each_spilled_reg consider narrow spills selftests/bpf: Add a test case for 32-bit spill tracking bpf: Add the assign_scalar_id_before_mov function bpf: Add the get_reg_width function bpf: Assign ID to scalars on spill selftests/bpf: Test assigning ID to scalars on spill bpf: Track spilled unbounded scalars selftests/bpf: Test tracking spilled unbounded scalars bpf: Preserve boundaries and track scalars on narrowing fill selftests/bpf: Add test cases for narrowing fill include/linux/bpf_verifier.h | 2 +- kernel/bpf/verifier.c | 160 +++++- .../bpf/progs/verifier_direct_packet_access.c | 2 +- .../selftests/bpf/progs/verifier_loops1.c | 24 + .../selftests/bpf/progs/verifier_spill_fill.c | 529 +++++++++++++++++- .../testing/selftests/bpf/verifier/precise.c | 6 +- 6 files changed, 677 insertions(+), 46 deletions(-) -- 2.42.1

[PATCH] kunit: Fix some comments which were mistakenly kerneldoc

by David Gow

The KUnit device helpers are documented with kerneldoc in their header file, but also have short comments over their implementation. These were mistakenly formatted as kerneldoc comments, even though they're not valid kerneldoc. It shouldn't cause any serious problems -- this file isn't included in the docs -- but it could be confusing, and causes warnings. Remove the extra '*' so that these aren't treated as kerneldoc.

[PATCH net-next] selftest/tcp-ao: Rectify out-of-tree build

by Dmitry Safonov

Trivial fix for out-of-tree build that I wasn't testing previously: 1. Create a directory for library object files, fixes: > gcc lib/kconfig.c -Wall -O2 -g -D_GNU_SOURCE -fno-strict-aliasing -I ../../../../../usr/include/ -iquote /tmp/kselftest/kselftest/net/tcp_ao/lib -I ../../../../include/ -o /tmp/kselftest/kselftest/net/tcp_ao/lib/kconfig.o -c > Assembler messages: > Fatal error: can't create /tmp/kselftest/kselftest/net/tcp_ao/lib/kconfig.o: No such file or directory > make[1]: *** [Makefile:46: /tmp/kselftest/kselftest/net/tcp_ao/lib/kconfig.o] Error 1 2. Include $(KHDR_INCLUDES) that's exported by selftests/Makefile, fixes: > In file included from lib/kconfig.c:6: > lib/aolib.h:320:45: warning: ‘struct tcp_ao_add’ declared inside parameter list will not be visible outside of this definition or declaration > 320 | extern int test_prepare_key_sockaddr(struct tcp_ao_add *ao, const char *alg, > | ^~~~~~~~~~ ... 3. While at here, clean-up $(KSFT_KHDR_INSTALL): it's not needed anymore since commit f2745dc0ba3d ("selftests: stop using KSFT_KHDR_INSTALL") 4. Also, while at here, drop .DEFAULT_GOAL definition: that has a self-explaining comment, that was valid when I made these selftests compile on local v4.19 kernel, but not needed since commit 8ce72dc32578 ("selftests: fix headers_install circular dependency") Fixes: cfbab37b3da0 ("selftests/net: Add TCP-AO library") Reported-by: kernel test robot <lkp(a)intel.com> Closes: https://lore.kernel.org/oe-kbuild-all/202312190645.q76MmHyq-lkp@intel.com/ Signed-off-by: Dmitry Safonov <dima(a)arista.com> --- tools/testing/selftests/net/tcp_ao/Makefile | 9 +++------ 1 file changed, 3 insertions(+), 6 deletions(-) diff --git a/tools/testing/selftests/net/tcp_ao/Makefile b/tools/testing/selftests/net/tcp_ao/Makefile index 6343cfcf919b..8e60bae67aa9 100644 --- a/tools/testing/selftests/net/tcp_ao/Makefile +++ b/tools/testing/selftests/net/tcp_ao/Makefile @@ -17,22 +17,18 @@ TEST_IPV6_PROGS := $(TEST_BOTH_AF:%=%_ipv6) TEST_GEN_PROGS := $(TEST_IPV4_PROGS) $(TEST_IPV6_PROGS) top_srcdir := ../../../../.. -KSFT_KHDR_INSTALL := 1 include ../../lib.mk HOSTAR ?= ar -# Drop it on port to linux/master with commit 8ce72dc32578 -.DEFAULT_GOAL := all - LIBDIR := $(OUTPUT)/lib LIB := $(LIBDIR)/libaotst.a LDLIBS += $(LIB) -pthread LIBDEPS := lib/aolib.h Makefile CFLAGS := -Wall -O2 -g -D_GNU_SOURCE -fno-strict-aliasing -CFLAGS += -I ../../../../../usr/include/ -iquote $(LIBDIR) -CFLAGS += -I ../../../../include/ +CFLAGS += $(KHDR_INCLUDES) +CFLAGS += -iquote ./lib/ -I ../../../../include/ # Library LIBSRC := kconfig.c netlink.c proc.c repair.c setup.c sock.c utils.c @@ -43,6 +39,7 @@ $(LIB): $(LIBOBJ) $(HOSTAR) rcs $@ $^ $(LIBDIR)/%.o: ./lib/%.c $(LIBDEPS) + mkdir -p $(LIBDIR) $(CC) $< $(CFLAGS) $(CPPFLAGS) -o $@ -c $(TEST_GEN_PROGS): $(LIB) --- base-commit: ceb2fe0d438644e1de06b9a6468a1fb8e2199c70 change-id: 20231219-b4-tcp-ao-selftests-out-of-tree-452f787f2d58 Best regards, -- Dmitry Safonov <dima(a)arista.com>

[PATCH v4] tracing/selftests: Add ownership modification tests for eventfs

by Steven Rostedt

From: "Steven Rostedt (Google)" <rostedt(a)goodmis.org> As there were bugs found with the ownership of eventfs dynamic file creation. Add a test to test it. It will remount tracefs with a different gid and check the ownership of the eventfs directory, as well as the system and event directories. It will also check the event file directories. It then does a chgrp on each of these as well to see if they all get updated as expected. Then it remounts the tracefs file system back to the original group and makes sure that all the updated files and directories were reset back to the original ownership. It does the same for instances that change the ownership of he instance directory. Note, because the uid is not reset by a remount, it is tested for every file by switching it to a new owner and then back again.

[PATCH RFC v2 00/22] KVM: arm64: Implement support for SME in non-protected guests

by Mark Brown

This series implements support for SME use in non-protected KVM guests. Much of this is very similar to SVE, the main additional challenge that SME presents is that it introduces two new controls which change the registers seen by guests: - PSTATE.ZA enables the ZA matrix register and, if SME2 is supported, the ZT0 LUT register. - PSTATE.SM enables streaming mode, a new floating point mode which uses the SVE register set with a separately configured vector length. In streaming mode implementation of the FFR register is optional. It is also permitted to build systems which support SME without SVE, in this case when not in streaming mode no SVE registers or instructions are available. Further, there is no requirement that there be any overlap in the set of vector lengths supported by SVE and SME in a system, this is expected to be a common situation in practical systems. Since there is a new vector length to configure we introduce a new feature parallel to the existing SVE one with a new pseudo register for the streaming mode vector length. Due to the overlap with SVE caused by streaming mode rather than finalising SME as a separate feature we use the existing SVE finalisation to also finalise SME, a new define KVM_ARM_VCPU_VEC is provided to help make user code clearer. Finalising SVE and SME separately would introduce complication with register access since finalising SVE makes the SVE regsiters writeable by userspace and doing multiple finalisations results in an error being reported. Dealing with a state where the SVE registers are writeable due to one of SVE or SME being finalised but may have their VL changed by the other being finalised seems like needless complexity with minimal practical utility, it seems clearer to just express directly that only one finalisation can be done in the ABI. We represent the streaming mode registers to userspace by always using the existing SVE registers to access the floating point state, using the larger of the SME and (if enabled for the guest) SVE vector lengths. There are a large number of subfeatures for SME, most of which only offer additional instructions but some of which (SME2 and FA64) add architectural state. The expectation is that these will be configured via the ID registers but since the mechanism for doing this is still unclear the current code enables SME2 and FA64 for the guest if the host supports them regardless of what the ID registers say. Since we do not yet have support for SVE in protected guests and SME is very reliant on SVE this series does not implement support for SME in protected guests. This will be added separately once SVE support is merged into mainline (or along with merging that), there is code for protected guests using SVE in the Android tree. The new KVM_ARM_VCPU_VEC feature and ZA and ZT0 registers have not been added to the get-reg-list selftest, the idea of supporting additional features there without restructuring the program to generate all possible feature combinations has been rejected.

[PATCH v2 1/2] kunit: Allow passing function pointer to kunit_activate_static_stub()

by Richard Fitzgerald

Swap the arguments to typecheck_fn() in kunit_activate_static_stub() so that real_fn_addr can be either the function itself or a pointer to that function. This is useful to simplify redirecting static functions in a module. Having to pass the actual function meant that it must be exported from the module. Either making the 'static' and EXPORT_SYMBOL*() conditional (which makes the code messy), or change it to always exported (which increases the export namespace and prevents the compiler inlining a trivial stub function in non-test builds). With the original definition of kunit_activate_static_stub() the address of real_fn_addr was passed to typecheck_fn() as the type to be passed. This meant that if real_fn_addr was a pointer-to-function it would resolve to a ** instead of a *, giving an error like this: error: initialization of ‘int (**)(int)’ from incompatible pointer type ‘int (*)(int)’ [-Werror=incompatible-pointer-types] kunit_activate_static_stub(test, add_one_fn_ptr, subtract_one); | ^~~~~~~~~~~~ ./include/linux/typecheck.h:21:25: note: in definition of macro ‘typecheck_fn’ 21 | ({ typeof(type) __tmp = function; \ Swapping the arguments to typecheck_fn makes it take the type of a pointer to the replacement function. Either a function or a pointer to function can be assigned to that. For example: static int some_function(int x) { /* whatever */ } int (* some_function_ptr)(int) = some_function; static int replacement(int x) { /* whatever */ } Then: kunit_activate_static_stub(test, some_function, replacement); yields: typecheck_fn(typeof(&replacement), some_function); and: kunit_activate_static_stub(test, some_function_ptr, replacement); yields: typecheck_fn(typeof(&replacement), some_function_ptr); The two typecheck_fn() then resolve to: int (*__tmp)(int) = some_function; and int (*__tmp)(int) = some_function_ptr; Both of these are valid. In the first case the compiler inserts an implicit '&' to take the address of the supplied function, and in the second case the RHS is already a pointer to the same type.

[PATCH v2] tracing/selftests: Add ownership modification tests for eventfs

by Steven Rostedt

From: "Steven Rostedt (Google)" <rostedt(a)goodmis.org> As there were bugs found with the ownership of eventfs dynamic file creation. Add a test to test it. It will remount tracefs with a different gid and check the ownership of the eventfs directory, as well as the system and event directories. It will also check the event file directories. It then does a chgrp on each of these as well to see if they all get updated as expected. Then it remounts the tracefs file system back to the original group and makes sure that all the updated files and directories were reset back to the original ownership. It does the same for instances that change the ownership of he instance directory. Note, because the uid is not reset by a remount, it is tested for every file by switching it to a new owner and then back again.

[PATCH 0/2] kselftest/seccomp: Convert to KTAP output

by Mark Brown

Currently the seccomp benchmark selftest produces non-standard output, meaning that while it makes a number of checks of the performance it observes this has to be parsed by humans. This means that automated systems running this suite of tests are almost certainly ignoring the results which isn't ideal for spotting problems. Let's rework things so that each check that the program does is reported as a test result to the framework.

selftests/livepatch fails on s390

by Alexander Gordeev

Hi all, The livepatch selftest somehow fails in -next on s390 due to what appears to me as 'comm' usage issue. E.g the removal of timestamp- less line "with link type OSD_10GIG." in the below output forces 'comm' to produce the correct result in check_result() function of tools/testing/selftests/livepatch/functions.sh script: [ 11.229256] qeth 0.0.bd02: qdio: OSA on SC 2624 using AI:1 QEBSM:0 PRI:1 TDD:1 SIGA: W [ 11.250189] systemd-journald[943]: Successfully sent stream file descriptor to service manager.

But it was removed with commit 2f3f651f3756 ("selftests/livepatch: Use "comm" instead of "diff" for dmesg"). I am attaching the contents of "$expect" and "$result" script variables and the output of 'dmesg' before and after test run dmesg-saved.txt and dmesg.txt. Another 'dmesg' output dmesg-saved1.txt and dmesg1.txt also shows the same problem, which seems like something to do with sorting. The minimal reproducer attached is dmesg-saved1-rep.txt and dmesg1-rep.txt, that could be described as: --- dmesg-saved1-rep.txt 2023-12-17 21:08:14.171014218 +0100 +++ dmesg1-rep.txt 2023-12-17 21:06:52.221014218 +0100 @@ -1,3 +1,3 @@ -[ 98.820331] livepatch: 'test_klp_state2': starting patching transition [ 100.031067] livepatch: 'test_klp_state2': completing patching transition [ 284.224335] livepatch: kernel.ftrace_enabled = 1 +[ 284.232921] ===== TEST: basic shadow variable API ===== The culprit is the extra space in [ 98.820331] timestamp, that from the script point of view produces the output with two extra lines: [ 100.031067] livepatch: 'test_klp_state2': completing patching transition [ 284.224335] livepatch: kernel.ftrace_enabled = 1 [ 284.232921] ===== TEST: basic shadow variable API ===== If the line with [ 98.820331] timestamp removed or changed to e.g [ 100.031066] (aka 1 us less), then the result output is as expected: [ 284.232921] ===== TEST: basic shadow variable API ===== Thanks!

[PATCH v3 0/3] livepatch: Move modules to selftests and add a new test

by Marcos Paulo de Souza

This patchset moves the current kernel testing livepatch modules from lib/livepatches to tools/testing/selftest/livepatch/test_modules, and compiles them as out-of-tree modules before testing. There is also a new test being added. This new test exercises multiple processes calling a syscall, while a livepatch patched the syscall. Why this move is an improvement: * The modules are now compiled as out-of-tree modules against the current running kernel, making them capable of being tested on different systems with newer or older kernels. * Such approach now needs kernel-devel package to be installed, since they are out-of-tree modules. These can be generated by running "make rpm-pkg" in the kernel source. What needs to be solved: * Currently gen_tar only packages the resulting binaries of the tests, and not the sources. For the current approach, the newly added modules would be compiled and then packaged. It works when testing on a system with the same kernel version. But it will fail when running on a machine with different kernel version, since module was compiled against the kernel currently running. This is not a new problem, just aligning the expectations. For the current approach to be truly system agnostic gen_tar would need to include the module and program sources to be compiled in the target systems. I'm sending the patches now so it can be discussed before Plumbers. Thanks in advance!

[PATCH v11 00/19] KVM: xen: update shared_info and vcpu_info handling

From: Paul Durrant <pdurrant(a)amazon.com> This series has some small fixes from what was in version 10 [1]: * KVM: pfncache: allow a cache to be activated with a fixed (userspace) HVA This required a small fix to kvm_gpc_check() for an error that was introduced in version 8. * KVM: xen: separate initialization of shared_info cache and content This accidentally regressed a fix in commit 5d6d6a7d7e66a ("KVM: x86: Refine calculation of guest wall clock to use a single TSC read"). * KVM: xen: re-initialize shared_info if guest (32/64-bit) mode is set This mistakenly removed the initialization of shared_info from the code setting the KVM_XEN_ATTR_TYPE_SHARED_INFO attribute, which broke the self- tests. * KVM: xen: split up kvm_xen_set_evtchn_fast() This had a /32 and a /64 swapped in set_vcpu_info_evtchn_pending().

[PATCH bpf-next v5 0/4] bpf: support to track BPF_JNE

by Menglong Dong

For now, the reg bounds is not handled for BPF_JNE case, which can cause the failure of following case: /* The type of "a" is u32 */ if (a > 0 && a < 100) { /* the range of the register for a is [0, 99], not [1, 99], * and will cause the following error: * * invalid zero-sized read * * as a can be 0. */ bpf_skb_store_bytes(skb, xx, xx, a, 0); } In the code above, "a > 0" will be compiled to "if a == 0 goto xxx". In the TRUE branch, the dst_reg will be marked as known to 0. However, in the fallthrough(FALSE) branch, the dst_reg will not be handled, which makes the [min, max] for a is [0, 99], not [1, 99]. In the 1st patch, we reduce the range of the dst reg if the src reg is a const and is exactly the edge of the dst reg For BPF_JNE. In the 2nd patch, we remove reduplicated s32 casting in "crafted_cases". In the 3rd patch, we just activate the test case for this logic in range_cond(), which is committed by Andrii in the commit 8863238993e2 ("selftests/bpf: BPF register range bounds tester"). In the 4th patch, we convert the case above to a testcase and add it to verifier_bounds.c. Changes since v4: - add the 2nd patch - add "{U32, U32, {0, U32_MAX}, {U32_MAX, U32_MAX}}" that we missed in the 3rd patch - add some comments to the function that we add in the 4th patch - add reg_not_equal_const() in the 4th patch Changes since v3: - do some adjustment to the crafted cases that we added in the 2nd patch - add the 3rd patch Changes since v2: - fix a typo in the subject of the 1st patch - add some comments to the 1st patch, as Eduard advised - add some cases to the "crafted_cases" Changes since v1: - simplify the code in the 1st patch - introduce the 2nd patch for the testing Menglong Dong (4): bpf: make the verifier tracks the "not equal" for regs selftests/bpf: remove reduplicated s32 casting in "crafted_cases" selftests/bpf: activate the OP_NE logic in range_cond() selftests/bpf: add testcase to verifier_bounds.c for BPF_JNE kernel/bpf/verifier.c | 38 +++++++++++- .../selftests/bpf/prog_tests/reg_bounds.c | 27 +++++--- .../selftests/bpf/progs/verifier_bounds.c | 62 +++++++++++++++++++ 3 files changed, 116 insertions(+), 11 deletions(-) -- 2.39.2

[PATCH 1/2] kunit: Allow passing function pointer to kunit_activate_static_stub()

by Richard Fitzgerald

Swap the arguments to typecheck_fn() in kunit_activate_static_stub() so that real_fn_addr can be either the function itself or a pointer to that function. This is useful to simplify redirecting static functions in a module. Having to pass the actual function meant that it must be exported from the module. Either making the 'static' and EXPORT_SYMBOL*() conditional (which makes the code messy), or change it to always exported (which increases the export namespace and prevents the compiler inlining a trivial stub function in non-test builds). With the original definition of kunit_activate_static_stub() the address of real_fn_addr was passed to typecheck_fn() as the type to be passed. This meant that if real_fn_addr was a pointer-to-function it would resolve to a ** instead of a *, giving an error like this: error: initialization of ‘int (**)(int)’ from incompatible pointer type ‘int (*)(int)’ [-Werror=incompatible-pointer-types] kunit_activate_static_stub(test, add_one_fn_ptr, subtract_one); | ^~~~~~~~~~~~ ./include/linux/typecheck.h:21:25: note: in definition of macro ‘typecheck_fn’ 21 | ({ typeof(type) __tmp = function; \ Swapping the arguments to typecheck_fn makes it take the type of a pointer to the replacement function. Either a function or a pointer to function can be assigned to that. For example: static int some_function(int x) { /* whatever */ } int (* some_function_ptr)(int) = some_function; static int replacement(int x) { /* whatever */ } Then: kunit_activate_static_stub(test, some_function, replacement); yields: typecheck_fn(typeof(&replacement), some_function); and: kunit_activate_static_stub(test, some_function_ptr, replacement); yields: typecheck_fn(typeof(&replacement), some_function_ptr); The two typecheck_fn() then resolve to: int (*__tmp)(int) = some_function; and int (*__tmp)(int) = some_function_ptr; Both of these are valid. In the first case the compiler inserts an implicit '&' to take the address of the supplied function, and in the second case the RHS is already a pointer to the same type.

[PATCH] selftests/seccomp: Try to fit runtime of benchmark into timeout

by Mark Brown

The seccomp benchmark runs five scenarios, one calibration run with no seccomp filters enabled then four further runs each adding a filter. The calibration run times itself for 15s and then each additional run executes for the same number of times. Currently the seccomp tests, including the benchmark, run with an extended 120s timeout but this is not sufficient to robustly run the tests on a lot of platforms. Sample timings from some recent runs: Platform Run 1 Run 2 Run 3 Run 4 --------- ----- ----- ----- ----- PowerEdge R200 16.6s 16.6s 31.6s 37.4s BBB (arm) 20.4s 20.4s 54.5s Synquacer (arm64) 20.7s 23.7s 40.3s The x86 runs from the PowerEdge are quite marginal and routinely fail, for the successful run reported here the timed portions of the run are at 117.2s leaving less than 3s of margin which is frequently breached. The added overhead of adding filters on the other platforms is such that there is no prospect of their runs fitting into the 120s timeout, especially on 32 bit arm where there is no BPF JIT. While we could lower the time we calibrate for I'm also already seeing the currently completing runs reporting issues with the per filter overheads not matching expectations: Let's instead raise the timeout to 180s which is only a 50% increase on the current timeout which is itself not *too* large given that there's only two tests in this suite.
