[PATCH bpf-next 0/4] L2 encap support for bpf_skb_adjust_room

by Alan Maguire

Extend bpf_skb_adjust_room growth to mark inner MAC header so that L2 encapsulation can be used for tc tunnels. Patch #1 extends the existing test_tc_tunnel to support UDP encapsulation; later we want to be able to test MPLS over UDP and MPLS over GRE encapsulation. Patch #2 adds the BPF_F_ADJ_ROOM_ENCAP_L2(len) macro, which allows specification of inner mac length. Other approaches were explored prior to taking this approach. Specifically, I tried automatically computing the inner mac length on the basis of the specified flags (so inner maclen for GRE/IPv4 encap is the len_diff specified to bpf_skb_adjust_room minus GRE + IPv4 header length for example). Problem with this is that we don't know for sure what form of GRE/UDP header we have; is it a full GRE header, or is it a FOU UDP header or generic UDP encap header? My fear here was we'd end up with an explosion of flags. The other approach tried was to support inner L2 header marking as a separate room adjustment, i.e. adjust for L3/L4 encap, then call bpf_skb_adjust_room for L2 encap. This can be made to work but because it imposed an order on operations, felt a bit clunky. Patch #3 syncs tools/ bpf.h. Patch #4 extends the tests again to support MPLSoverGRE and MPLSoverUDP encap, along with existing test coverage. Alan Maguire (4): selftests_bpf: extend test_tc_tunnel for UDP encap bpf: add layer 2 encap support to bpf_skb_adjust_room bpf: sync bpf.h to tools/ for BPF_F_ADJ_ROOM_ENCAP_L2 selftests_bpf: extend test_tc_tunnel.sh test for L2 encap include/uapi/linux/bpf.h | 5 + net/core/filter.c | 19 +- tools/include/uapi/linux/bpf.h | 5 + tools/testing/selftests/bpf/progs/test_tc_tunnel.c | 281 ++++++++++++++++----- tools/testing/selftests/bpf/test_tc_tunnel.sh | 105 +++++--- 5 files changed, 318 insertions(+), 97 deletions(-) -- 1.8.3.1

[PATCH v14 6/6] selftests: media_dev_allocator api test

by Shuah Khan

Add a new test for Media Device Allocator API. Media Device Allocator API to allows multiple drivers share a media device. This API solves a very common use-case for media devices where one physical device (an USB stick) provides both audio and video. When such media device exposes a standard USB Audio class, a proprietary Video class, two or more independent drivers will share a single physical USB bridge. In such cases, it is necessary to coordinate access to the shared resource. Using this API, drivers can allocate a media device with the shared struct device as the key. Once the media device is allocated by a driver, other drivers can get a reference to it. The media device is released when all the references are released. This test does a series of unbind/bind tests to make sure media device is released correctly when it is no longer is use and when the last driver releases the reference.

[PATCH v13 6/6] selftests: media_dev_allocator api test

by Shuah Khan

Add a new test for Media Device Allocator API. Media Device Allocator API to allows multiple drivers share a media device. This API solves a very common use-case for media devices where one physical device (an USB stick) provides both audio and video. When such media device exposes a standard USB Audio class, a proprietary Video class, two or more independent drivers will share a single physical USB bridge. In such cases, it is necessary to coordinate access to the shared resource. Using this API, drivers can allocate a media device with the shared struct device as the key. Once the media device is allocated by a driver, other drivers can get a reference to it. The media device is released when all the references are released. This test does a series of unbind/bind tests to make sure media device is released correctly when it is no longer is use and when the last driver releases the reference.

[PATCH v2 1/4] lockdep: Add assertion to check if in an interrupt

by Joel Fernandes (Google)

In rcu_rrupt_from_idle, we want to check if it is called from within an interrupt, but want to do such checking only for debug builds. lockdep already tracks when we enter an interrupt. Let us expose it as an assertion macro so it can be used to assert this.

[PATCH AUTOSEL 4.19 103/192] selftests: skip seccomp get_metadata test if not real root

by Sasha Levin

From: Tycho Andersen <tycho(a)tycho.ws> [ Upstream commit 3aa415dd2128e478ea3225b59308766de0e94d6b ] The get_metadata() test requires real root, so let's skip it if we're not real root. Note that I used XFAIL here because that's what the test does later if CONFIG_CHEKCKPOINT_RESTORE happens to not be enabled. After looking at the code, there doesn't seem to be a nice way to skip tests defined as TEST(), since there's no return code (I tried exit(KSFT_SKIP), but that didn't work either...). So let's do it this way to be consistent, and easier to fix when someone comes along and fixes it.

From: Breno Leitao <leitao(a)debian.org> [ Upstream commit dd9cef43c222df7c0d76d34451808e789952379d ] When compiling test_maps selftest with GCC-8, it warns that an array might be indexed with a negative value, which could cause a negative out of bound access, depending on parameters of the function. This is the GCC-8 warning: gcc -Wall -O2 -I../../../include/uapi -I../../../lib -I../../../lib/bpf -I../../../../include/generated -DHAVE_GENHDR -I../../../include test_maps.c /home/breno/Devel/linux/tools/testing/selftests/bpf/libbpf.a -lcap -lelf -lrt -lpthread -o /home/breno/Devel/linux/tools/testing/selftests/bpf/test_maps In file included from test_maps.c:16: test_maps.c: In function ‘run_all_tests’: test_maps.c:1079:10: warning: array subscript -1 is below array bounds of ‘pid_t[<Ube20> + 1]’ [-Warray-bounds] assert(waitpid(pid[i], &status, 0) == pid[i]); ^~~~~~~~~~~~~~~~~~~~~~~~~~~ test_maps.c:1059:6: warning: array subscript -1 is below array bounds of ‘pid_t[<Ube20> + 1]’ [-Warray-bounds] pid[i] = fork(); ~~~^~~ This patch simply guarantees that the task(s) variables are unsigned, thus, they could never be a negative number (which they are not in current code anyway), hence avoiding an out of bound access warning.

[PATCH AUTOSEL 5.0 149/262] selftests: skip seccomp get_metadata test if not real root

by Sasha Levin

From: Tycho Andersen <tycho(a)tycho.ws> [ Upstream commit 3aa415dd2128e478ea3225b59308766de0e94d6b ] The get_metadata() test requires real root, so let's skip it if we're not real root. Note that I used XFAIL here because that's what the test does later if CONFIG_CHEKCKPOINT_RESTORE happens to not be enabled. After looking at the code, there doesn't seem to be a nice way to skip tests defined as TEST(), since there's no return code (I tried exit(KSFT_SKIP), but that didn't work either...). So let's do it this way to be consistent, and easier to fix when someone comes along and fixes it.

[PATCH] rcutorture: Select from only online CPUs

by Joel Fernandes (Google)

The rcutorture jitter.sh script selects a random CPU but does not check if it is offline or online. This leads to taskset errors many times. On my machine, hyper threading is disabled so half the cores are offline causing taskset errors a lot of times. Let us fix this by checking from only the online CPUs on the system.

[RFC v4 00/17] kunit: introduce KUnit, the Linux kernel unit testing framework

by Brendan Higgins

This patch set proposes KUnit, a lightweight unit testing and mocking framework for the Linux kernel. Unlike Autotest and kselftest, KUnit is a true unit testing framework; it does not require installing the kernel on a test machine or in a VM and does not require tests to be written in userspace running on a host kernel. Additionally, KUnit is fast: From invocation to completion KUnit can run several dozen tests in under a second. Currently, the entire KUnit test suite for KUnit runs in under a second from the initial invocation (build time excluded). KUnit is heavily inspired by JUnit, Python's unittest.mock, and Googletest/Googlemock for C++. KUnit provides facilities for defining unit test cases, grouping related test cases into test suites, providing common infrastructure for running tests, mocking, spying, and much more. ## What's so special about unit testing? A unit test is supposed to test a single unit of code in isolation, hence the name. There should be no dependencies outside the control of the test; this means no external dependencies, which makes tests orders of magnitudes faster. Likewise, since there are no external dependencies, there are no hoops to jump through to run the tests. Additionally, this makes unit tests deterministic: a failing unit test always indicates a problem. Finally, because unit tests necessarily have finer granularity, they are able to test all code paths easily solving the classic problem of difficulty in exercising error handling code. ## Is KUnit trying to replace other testing frameworks for the kernel? No. Most existing tests for the Linux kernel are end-to-end tests, which have their place. A well tested system has lots of unit tests, a reasonable number of integration tests, and some end-to-end tests. KUnit is just trying to address the unit test space which is currently not being addressed. ## More information on KUnit There is a bunch of documentation near the end of this patch set that describes how to use KUnit and best practices for writing unit tests. For convenience I am hosting the compiled docs here: https://google.github.io/kunit-docs/third_party/kernel/docs/ Additionally for convenience, I have applied these patches to a branch: https://kunit.googlesource.com/linux/+/kunit/rfc/5.0-rc5/v4 The repo may be cloned with: git clone https://kunit.googlesource.com/linux This patchset is on the kunit/rfc/5.0-rc5/v4 branch. ## Changes Since Last Version - Got KUnit working on (hypothetically) all architectures (tested on x86), as per Rob's (and other's) request - Punting all KUnit features/patches depending on UML for now. - Broke out UML specific support into arch/um/* as per "[RFC v3 01/19] kunit: test: add KUnit test runner core", as requested by Luis. - Added support to kunit_tool to allow it to build kernels in external directories, as suggested by Kieran. - Added a UML defconfig, and a config fragment for KUnit as suggested by Kieran and Luis. - Cleaned up, and reformatted a bunch of stuff. -- 2.21.0.rc0.258.g878e2cd30e-goog

[PATCH v3 00/10] Support using MSI interrupts in ntb_transport

by Logan Gunthorpe

This is version 3 of the MSI interrupts for ntb_transport patchset. I've addressed the feedback so far and rebased on the latest kernel and would like this to be considered for merging this cycle. The only outstanding issue I know of is that it still will not work with IDT hardware, but ntb_transport doesn't work with IDT hardware and there is still no sensible common infrastructure to support ntb_peer_mw_set_trans(). Thus, I decline to consider that complication in this patchset. However, I'll be happy to review work that adds this feature in the future. Also as the port number and resource index stuff is a bit complicated, I made a quick out of tree test fixture to ensure it's correct[1]. As an excerise I also wrote some test code[2] using the upcomming KUnit feature. Logan [1] https://repl.it/repls/ExcitingPresentFile [2] https://github.com/sbates130272/linux-p2pmem/commits/ntb_kunit -- Changes in v3: * Rebased onto v5.1-rc1 (Dropped the first two patches as they have been merged, and cleaned up some minor conflicts in the PCI tree) * Added a new patch (#3) to calculate logical port numbers that are port numbers from 0 to (number of ports - 1). This is then used in ntb_peer_resource_idx() to fix the issues brought up by Serge. * Fixed missing __iomem and iowrite calls (as noticed by Serge) * Added patch 10 which describes ntb_msi_test in the documentation file (as requested by Serge) * A couple other minor nits and documentation fixes -- Changes in v2: * Cleaned up the changes in intel_irq_remapping.c to make them less confusing and add a comment. (Per discussion with Jacob and Joerg) * Fixed a nit from Bjorn and collected his Ack * Added a Kconfig dependancy on CONFIG_PCI_MSI for CONFIG_NTB_MSI as the Kbuild robot hit a random config that didn't build without it. * Worked in a callback for when the MSI descriptor changes so that the clients can resend the new address and data values to the peer. On my test system this was never necessary, but there may be other platforms where this can occur. I tested this by hacking in a path to rewrite the MSI descriptor when I change the cpu affinity of an IRQ. There's a bit of uncertainty over the latency of the change, but without hardware this can acctually occur on we can't test this. This was the result of a discussion with Dave. -- This patch series adds optional support for using MSI interrupts instead of NTB doorbells in ntb_transport. This is desirable seeing doorbells on current hardware are quite slow and therefore switching to MSI interrupts provides a significant performance gain. On switchtec hardware, a simple apples-to-apples comparison shows ntb_netdev/iperf numbers going from 3.88Gb/s to 14.1Gb/s when switching to MSI interrupts. To do this, a couple changes are required outside of the NTB tree: 1) The IOMMU must know to accept MSI requests from aliased bused numbers seeing NTB hardware typically sends proxied request IDs through additional requester IDs. The first patch in this series adds support for the Intel IOMMU. A quirk to add these aliases for switchtec hardware was already accepted. See commit ad281ecf1c7d ("PCI: Add DMA alias quirk for Microsemi Switchtec NTB") for a description of NTB proxy IDs and why this is necessary. 2) NTB transport (and other clients) may often need more MSI interrupts than the NTB hardware actually advertises support for. However, seeing these interrupts will not be triggered by the hardware but through an NTB memory window, the hardware does not actually need support or need to know about them. Therefore we add the concept of Virtual MSI interrupts which are allocated just like any other MSI interrupt but are not programmed into the hardware's MSI table. This is done in Patch 2 and then made use of in Patch 3. The remaining patches in this series add a library for dealing with MSI interrupts, a test client and finally support in ntb_transport. The series is based off of v5.1-rc1 plus the patches in ntb-next.

[PATCH bpf-next] bpf: test_tc_tunnel.sh needs reverse path filtering disabled

by Alan Maguire

test_tc_tunnel.sh sets up a pair of namespaces connected by a veth pair to verify encap/decap using bpf_skb_adjust_room. In testing this, it uses tunnel links as the peer of the bpf-based encap/decap. However because the same IP header is used for inner and outer IP, when packets arrive at the tunnel interface they will be dropped by reverse path filtering as those packets are expected on the veth interface (where the destination IP of the decapped packet is configured). To avoid this, ensure reverse path filtering is disabled for the namespace using tunneling.

[PATCH linux-next v8 0/7] ptrace: add PTRACE_GET_SYSCALL_INFO request

by Dmitry V. Levin

PTRACE_GET_SYSCALL_INFO is a generic ptrace API that lets ptracer obtain details of the syscall the tracee is blocked in. There are two reasons for a special syscall-related ptrace request. Firstly, with the current ptrace API there are cases when ptracer cannot retrieve necessary information about syscalls. Some examples include: * The notorious int-0x80-from-64-bit-task issue. See [1] for details. In short, if a 64-bit task performs a syscall through int 0x80, its tracer has no reliable means to find out that the syscall was, in fact, a compat syscall, and misidentifies it. * Syscall-enter-stop and syscall-exit-stop look the same for the tracer. Common practice is to keep track of the sequence of ptrace-stops in order not to mix the two syscall-stops up. But it is not as simple as it looks; for example, strace had a (just recently fixed) long-standing bug where attaching strace to a tracee that is performing the execve system call led to the tracer identifying the following syscall-exit-stop as syscall-enter-stop, which messed up all the state tracking. * Since the introduction of commit 84d77d3f06e7e8dea057d10e8ec77ad71f721be3 ("ptrace: Don't allow accessing an undumpable mm"), both PTRACE_PEEKDATA and process_vm_readv become unavailable when the process dumpable flag is cleared. On such architectures as ia64 this results in all syscall arguments being unavailable for the tracer. Secondly, ptracers also have to support a lot of arch-specific code for obtaining information about the tracee. For some architectures, this requires a ptrace(PTRACE_PEEKUSER, ...) invocation for every syscall argument and return value. PTRACE_GET_SYSCALL_INFO returns the following structure: struct ptrace_syscall_info { __u8 op; /* PTRACE_SYSCALL_INFO_* */ __u32 arch __attribute__((__aligned__(sizeof(__u32)))); __u64 instruction_pointer; __u64 stack_pointer; union { struct { __u64 nr; __u64 args[6]; } entry; struct { __s64 rval; __u8 is_error; } exit; struct { __u64 nr; __u64 args[6]; __u32 ret_data; } seccomp; }; }; The structure was chosen according to [2], except for the following changes: * seccomp substructure was added as a superset of entry substructure; * the type of nr field was changed from int to __u64 because syscall numbers are, as a practical matter, 64 bits; * stack_pointer field was added along with instruction_pointer field since it is readily available and can save the tracer from extra PTRACE_GETREGS/PTRACE_GETREGSET calls; * arch is always initialized to aid with tracing system calls * such as execve(); * instruction_pointer and stack_pointer are always initialized so they could be easily obtained for non-syscall stops; * a boolean is_error field was added along with rval field, this way the tracer can more reliably distinguish a return value from an error value. strace has been ported to PTRACE_GET_SYSCALL_INFO. Starting with release 4.26, strace uses PTRACE_GET_SYSCALL_INFO API as the preferred mechanism of obtaining syscall information.

[PATCHv2 bpf-next 1/3] bpf, tests: tweak endianness selection

by Sergey Senozhatsky

Not all compilers have __builtin_bswap16() and __builtin_bswap32(), thus not all compilers are able to compile the following code: (__builtin_constant_p(x) ? \ ___constant_swab16(x) : __builtin_bswap16(x)) That's the reason why bpf_ntohl() doesn't work on GCC < 4.8, for instance: error: implicit declaration of function '__builtin_bswap16' We can use __builtin_bswap16() only if compiler has this built-in, that is, only if __HAVE_BUILTIN_BSWAP16__ is defined. Standard UAPI __swab16()/__swab32() take care of that, and, additionally, handle __builtin_constant_p() cases as well: #ifdef __HAVE_BUILTIN_BSWAP16__ #define __swab16(x) (__u16)__builtin_bswap16((__u16)(x)) #else #define __swab16(x) \ (__builtin_constant_p((__u16)(x)) ? \ ___constant_swab16(x) : \ __fswab16(x)) #endif So we can tweak selftests/bpf/bpf_endian.h and use UAPI __swab16()/__swab32().

[PATCH net-next] selftests: bpf: modify urandom_read and link it non-statically

by Ivan Vecera

After some experiences I found that urandom_read does not need to be linked statically. When the 'read' syscall call is moved to separate non-inlined function then bpf_get_stackid() is able to find the executable in stack trace and extract its build_id from it.

[PATCH v13 00/20] arm64: untag user pointers passed to the kernel

by Andrey Konovalov

=== Overview arm64 has a feature called Top Byte Ignore, which allows to embed pointer tags into the top byte of each pointer. Userspace programs (such as HWASan, a memory debugging tool [1]) might use this feature and pass tagged user pointers to the kernel through syscalls or other interfaces. Right now the kernel is already able to handle user faults with tagged pointers, due to these patches: 1. 81cddd65 ("arm64: traps: fix userspace cache maintenance emulation on a tagged pointer") 2. 7dcd9dd8 ("arm64: hw_breakpoint: fix watchpoint matching for tagged pointers") 3. 276e9327 ("arm64: entry: improve data abort handling of tagged pointers") This patchset extends tagged pointer support to syscall arguments. As per the proposed ABI change [3], tagged pointers are only allowed to be passed to syscalls when they point to memory ranges obtained by anonymous mmap() or sbrk() (see the patchset [3] for more details). For non-memory syscalls this is done by untaging user pointers when the kernel performs pointer checking to find out whether the pointer comes from userspace (most notably in access_ok). The untagging is done only when the pointer is being checked, the tag is preserved as the pointer makes its way through the kernel and stays tagged when the kernel dereferences the pointer when perfoming user memory accesses. Memory syscalls (mmap, mprotect, etc.) don't do user memory accesses but rather deal with memory ranges, and untagged pointers are better suited to describe memory ranges internally. Thus for memory syscalls we untag pointers completely when they enter the kernel. === Other approaches One of the alternative approaches to untagging that was considered is to completely strip the pointer tag as the pointer enters the kernel with some kind of a syscall wrapper, but that won't work with the countless number of different ioctl calls. With this approach we would need a custom wrapper for each ioctl variation, which doesn't seem practical. An alternative approach to untagging pointers in memory syscalls prologues is to inspead allow tagged pointers to be passed to find_vma() (and other vma related functions) and untag them there. Unfortunately, a lot of find_vma() callers then compare or subtract the returned vma start and end fields against the pointer that was being searched. Thus this approach would still require changing all find_vma() callers. === Testing The following testing approaches has been taken to find potential issues with user pointer untagging: 1. Static testing (with sparse [2] and separately with a custom static analyzer based on Clang) to track casts of __user pointers to integer types to find places where untagging needs to be done. 2. Static testing with grep to find parts of the kernel that call find_vma() (and other similar functions) or directly compare against vm_start/vm_end fields of vma. 3. Static testing with grep to find parts of the kernel that compare user pointers with TASK_SIZE or other similar consts and macros. 4. Dynamic testing: adding BUG_ON(has_tag(addr)) to find_vma() and running a modified syzkaller version that passes tagged pointers to the kernel. Based on the results of the testing the requried patches have been added to the patchset. === Notes This patchset is meant to be merged together with "arm64 relaxed ABI" [3]. This patchset is a prerequisite for ARM's memory tagging hardware feature support [4]. This patchset has been merged into the Pixel 2 kernel tree and is now being used to enable testing of Pixel 2 phones with HWASan. Thanks!

Changes in v12: - Changed untagging in tcp_zerocopy_receive() to also untag zc->address. - Fixed untagging in prctl_set_mm* to only untag pointers for vma lookups and validity checks, but leave them as is for actual user space accesses. - Updated the link to the v2 of the "arm64 relaxed ABI" patchset [3]. - Dropped the documentation patch, as the "arm64 relaxed ABI" patchset [3] handles that. Changes in v11: - Added "uprobes, arm64: untag user pointers in find_active_uprobe" patch. - Added "bpf, arm64: untag user pointers in stack_map_get_build_id_offset" patch. - Fixed "tracing, arm64: untag user pointers in seq_print_user_ip" to correctly perform subtration with a tagged addr. - Moved untagged_addr() from SYSCALL_DEFINE3(mprotect) and SYSCALL_DEFINE4(pkey_mprotect) to do_mprotect_pkey(). - Moved untagged_addr() definition for other arches from include/linux/memory.h to include/linux/mm.h. - Changed untagging in strn*_user() to perform userspace accesses through tagged pointers. - Updated the documentation to mention that passing tagged pointers to memory syscalls is allowed. - Updated the test to use malloc'ed memory instead of stack memory.

Did a test with a embedded ima key in kernel, with secure boot disabled, but with Secure Boot enabled, but failed to sign the kernel with both pesign and evmctl, will continue to see how to work on it and ask in private email if needed :) About the patch itself, as we talked in another email, I would expect it can work with other test cases eg. without IMA/secure boot. But if that is not easy, maybe you can change the test script filename to something like: test_kexec_load_sigcheck.sh and test_kexec_file_load_sigcheck.sh then we can add other non-sigcheck related cases to other test scripts later. But ideally if we can handle them in current files it would be better. Another issue I noticed is even if boot with ima_appraise=off, kexec load still checking the conditions. Will see if I'm having something wrong in test steps. Thanks Dave

[PATCH v12 00/13] arm64: untag user pointers passed to the kernel

by Andrey Konovalov

=== Overview arm64 has a feature called Top Byte Ignore, which allows to embed pointer tags into the top byte of each pointer. Userspace programs (such as HWASan, a memory debugging tool [1]) might use this feature and pass tagged user pointers to the kernel through syscalls or other interfaces. Right now the kernel is already able to handle user faults with tagged pointers, due to these patches: 1. 81cddd65 ("arm64: traps: fix userspace cache maintenance emulation on a tagged pointer") 2. 7dcd9dd8 ("arm64: hw_breakpoint: fix watchpoint matching for tagged pointers") 3. 276e9327 ("arm64: entry: improve data abort handling of tagged pointers") This patchset extends tagged pointer support to syscall arguments. As per the proposed ABI change [3], tagged pointers are only allowed to be passed to syscalls when they point to memory ranges obtained by anonymous mmap() or sbrk() (see the patchset [3] for more details). For non-memory syscalls this is done by untaging user pointers when the kernel performs pointer checking to find out whether the pointer comes from userspace (most notably in access_ok). The untagging is done only when the pointer is being checked, the tag is preserved as the pointer makes its way through the kernel and stays tagged when the kernel dereferences the pointer when perfoming user memory accesses. Memory syscalls (mmap, mprotect, etc.) don't do user memory accesses but rather deal with memory ranges, and untagged pointers are better suited to describe memory ranges internally. Thus for memory syscalls we untag pointers completely when they enter the kernel. === Other approaches One of the alternative approaches to untagging that was considered is to completely strip the pointer tag as the pointer enters the kernel with some kind of a syscall wrapper, but that won't work with the countless number of different ioctl calls. With this approach we would need a custom wrapper for each ioctl variation, which doesn't seem practical. An alternative approach to untagging pointers in memory syscalls prologues is to inspead allow tagged pointers to be passed to find_vma() (and other vma related functions) and untag them there. Unfortunately, a lot of find_vma() callers then compare or subtract the returned vma start and end fields against the pointer that was being searched. Thus this approach would still require changing all find_vma() callers. === Testing The following testing approaches has been taken to find potential issues with user pointer untagging: 1. Static testing (with sparse [2] and separately with a custom static analyzer based on Clang) to track casts of __user pointers to integer types to find places where untagging needs to be done. 2. Static testing with grep to find parts of the kernel that call find_vma() (and other similar functions) or directly compare against vm_start/vm_end fields of vma. 3. Static testing with grep to find parts of the kernel that compare user pointers with TASK_SIZE or other similar consts and macros. 4. Dynamic testing: adding BUG_ON(has_tag(addr)) to find_vma() and running a modified syzkaller version that passes tagged pointers to the kernel. Based on the results of the testing the requried patches have been added to the patchset. === Notes This patchset is meant to be merged together with "arm64 relaxed ABI" [3]. This patchset is a prerequisite for ARM's memory tagging hardware feature support [4]. This patchset has been merged into the Pixel 2 kernel tree and is now being used to enable testing of Pixel 2 phones with HWASan. Thanks! [1] http://clang.llvm.org/docs/HardwareAssistedAddressSanitizerDesign.html [2] https://github.com/lucvoo/sparse-dev/commit/5f960cb10f56ec2017c128ef9d16060… [3] https://lkml.org/lkml/2019/3/18/819 [4] https://community.arm.com/processors/b/blog/posts/arm-a-profile-architectur… Changes in v12: - Changed untagging in tcp_zerocopy_receive() to also untag zc->address. - Fixed untagging in prctl_set_mm* to only untag pointers for vma lookups and validity checks, but leave them as is for actual user space accesses. - Updated the link to the v2 of the "arm64 relaxed ABI" patchset [3]. - Dropped the documentation patch, as the "arm64 relaxed ABI" patchset [3] handles that. Changes in v11: - Added "uprobes, arm64: untag user pointers in find_active_uprobe" patch. - Added "bpf, arm64: untag user pointers in stack_map_get_build_id_offset" patch. - Fixed "tracing, arm64: untag user pointers in seq_print_user_ip" to correctly perform subtration with a tagged addr. - Moved untagged_addr() from SYSCALL_DEFINE3(mprotect) and SYSCALL_DEFINE4(pkey_mprotect) to do_mprotect_pkey(). - Moved untagged_addr() definition for other arches from include/linux/memory.h to include/linux/mm.h. - Changed untagging in strn*_user() to perform userspace accesses through tagged pointers. - Updated the documentation to mention that passing tagged pointers to memory syscalls is allowed. - Updated the test to use malloc'ed memory instead of stack memory. Changes in v10: - Added "mm, arm64: untag user pointers passed to memory syscalls" back. - New patch "fs, arm64: untag user pointers in fs/userfaultfd.c". - New patch "net, arm64: untag user pointers in tcp_zerocopy_receive". - New patch "kernel, arm64: untag user pointers in prctl_set_mm*". - New patch "tracing, arm64: untag user pointers in seq_print_user_ip". Changes in v9: - Rebased onto 4.20-rc6. - Used u64 instead of __u64 in type casts in the untagged_addr macro for arm64. - Added braces around (addr) in the untagged_addr macro for other arches. Changes in v8: - Rebased onto 65102238 (4.20-rc1). - Added a note to the cover letter on why syscall wrappers/shims that untag user pointers won't work. - Added a note to the cover letter that this patchset has been merged into the Pixel 2 kernel tree. - Documentation fixes, in particular added a list of syscalls that don't support tagged user pointers. Changes in v7: - Rebased onto 17b57b18 (4.19-rc6). - Dropped the "arm64: untag user address in __do_user_fault" patch, since the existing patches already handle user faults properly. - Dropped the "usb, arm64: untag user addresses in devio" patch, since the passed pointer must come from a vma and therefore be untagged. - Dropped the "arm64: annotate user pointers casts detected by sparse" patch (see the discussion to the replies of the v6 of this patchset). - Added more context to the cover letter. - Updated Documentation/arm64/tagged-pointers.txt. Changes in v6: - Added annotations for user pointer casts found by sparse. - Rebased onto 050cdc6c (4.19-rc1+). Changes in v5: - Added 3 new patches that add untagging to places found with static analysis. - Rebased onto 44c929e1 (4.18-rc8). Changes in v4: - Added a selftest for checking that passing tagged pointers to the kernel succeeds. - Rebased onto 81e97f013 (4.18-rc1+). Changes in v3: - Rebased onto e5c51f30 (4.17-rc6+). - Added linux-arch@ to the list of recipients. Changes in v2: - Rebased onto 2d618bdf (4.17-rc3+). - Removed excessive untagging in gup.c. - Removed untagging pointers returned from __uaccess_mask_ptr. Changes in v1: - Rebased onto 4.17-rc1. Changes in RFC v2: - Added "#ifndef untagged_addr..." fallback in linux/uaccess.h instead of defining it for each arch individually. - Updated Documentation/arm64/tagged-pointers.txt. - Dropped "mm, arm64: untag user addresses in memory syscalls". - Rebased onto 3eb2ce82 (4.16-rc7).

[PATCH] bpf, tests: tweak endianness selection

by Sergey Senozhatsky

Not all compilers have __builtin_bswap16() and __builtin_bswap32(), thus not all compilers are able to compile the following code (bpf_htons): (__builtin_constant_p(x) ? \ ___constant_swab16(x) : __builtin_bswap16(x)) That's why, for instance, bpf_htons() doesn't work on GCC < 4.8: error: implicit declaration of function '__builtin_bswap16' We can use __builtin_bswap16() only if compiler has this built-in, that is, only if __HAVE_BUILTIN_BSWAP16__ is defined. Standard UAPI __swab16()/__swab32() take care of that, and, additionally, handle __builtin_constant_p() cases as well (if compiler doesn't provide builtin bswap with constants folding): #ifdef __HAVE_BUILTIN_BSWAP16__ #define __swab16(x) (__u16)__builtin_bswap16((__u16)(x)) #else #define __swab16(x) \ (__builtin_constant_p((__u16)(x)) ? \ ___constant_swab16(x) : \ __fswab16(x)) #endif So we can tweak selftests/bpf/bpf_endian.h and use UAPI __swab16()/__swab32().

Re: [PATCH v4 1/2] Provide in-kernel headers for making it easy to extend the kernel

The Android use-case scenario might indeed have been the one to best crystallize the requirement, but that doesn't mean that all use-cases of eBPF wouldn't benefit from this -- which in fact they would, see instructions here for example on the need for kernel headers: https://github.com/iovisor/bcc/blob/master/INSTALL.md Just a quick $PREFERRED_SEARCH_ENGINE search returns interesting exchanges such as this one taken from a discussion thread on LWN covering an introduction to eBPF: https://lwn.net/Articles/741348/ Effectively this person had to be hand-held in understanding that they needed a good set of kernel headers to make the tool work. Their comment after being shown that this was needed was: "It looks like the headers package you need on Ubuntu is linux-headers-$(uname -r), which contains the entire kernel source tree, and is specific to the running kernel." Surely having Joel's patch in the kernel would obviate the issue for all Linux kernel users, not just Android.

[PATCH v9 6/9] kselftests: cgroup: add freezer controller self-tests

by Roman Gushchin

This patch implements 9 tests for the freezer controller for cgroup v2: 1) a simple test, which aims to freeze and unfreeze a cgroup with 100 processes 2) a more complicated tree test, which creates a hierarchy of cgroups, puts some processes in some cgroups, and tries to freeze and unfreeze different parts of the subtree 3) a forkbomb test: the test aims to freeze a forkbomb running in a cgroup, kill all tasks in the cgroup and remove the cgroup without the unfreezing. 4) rmdir test: the test creates two nested cgroups, freezes the parent one, checks that the child can be successfully removed, and a new child can be created 5) migration tests: the test checks migration of a task between frozen cgroups: from a frozen to a running, from a running to a frozen, and from a frozen to a frozen. 6) ptrace test: the test checks that it's possible to attach to a process in a frozen cgroup, get some information and detach, and the cgroup will remain frozen. 7) stopped test: the test checks that it's possible to freeze a cgroup with a stopped task 8) ptraced test: the test checks that it's possible to freeze a cgroup with a ptraced task 9) vfork test: the test checks that it's possible to freeze a cgroup with a parent process waiting for the child process in vfork() Expected output: $ ./test_freezer ok 1 test_cgfreezer_simple ok 2 test_cgfreezer_tree ok 3 test_cgfreezer_forkbomb ok 4 test_cgrreezer_rmdir ok 5 test_cgfreezer_migrate ok 6 test_cgfreezer_ptrace ok 7 test_cgfreezer_stopped ok 8 test_cgfreezer_ptraced ok 9 test_cgfreezer_vfork Signed-off-by: Roman Gushchin <guro(a)fb.com> Cc: Shuah Khan <shuah(a)kernel.org> Cc: Tejun Heo <tj(a)kernel.org> Cc: kernel-team(a)fb.com Cc: linux-kselftest(a)vger.kernel.org --- tools/testing/selftests/cgroup/.gitignore | 1 + tools/testing/selftests/cgroup/Makefile | 2 + tools/testing/selftests/cgroup/cgroup_util.c | 54 +- tools/testing/selftests/cgroup/cgroup_util.h | 5 + tools/testing/selftests/cgroup/test_freezer.c | 851 ++++++++++++++++++ 5 files changed, 912 insertions(+), 1 deletion(-) create mode 100644 tools/testing/selftests/cgroup/test_freezer.c diff --git a/tools/testing/selftests/cgroup/.gitignore b/tools/testing/selftests/cgroup/.gitignore index adacda50a4b2..7f9835624793 100644 --- a/tools/testing/selftests/cgroup/.gitignore +++ b/tools/testing/selftests/cgroup/.gitignore @@ -1,2 +1,3 @@ test_memcontrol test_core +test_freezer diff --git a/tools/testing/selftests/cgroup/Makefile b/tools/testing/selftests/cgroup/Makefile index 23fbaa4a9630..8d369b6a2069 100644 --- a/tools/testing/selftests/cgroup/Makefile +++ b/tools/testing/selftests/cgroup/Makefile @@ -5,8 +5,10 @@ all: TEST_GEN_PROGS = test_memcontrol TEST_GEN_PROGS += test_core +TEST_GEN_PROGS += test_freezer include ../lib.mk $(OUTPUT)/test_memcontrol: cgroup_util.c $(OUTPUT)/test_core: cgroup_util.c +$(OUTPUT)/test_freezer: cgroup_util.c diff --git a/tools/testing/selftests/cgroup/cgroup_util.c b/tools/testing/selftests/cgroup/cgroup_util.c index eba06f94433b..4c223266299a 100644 --- a/tools/testing/selftests/cgroup/cgroup_util.c +++ b/tools/testing/selftests/cgroup/cgroup_util.c @@ -74,6 +74,16 @@ char *cg_name_indexed(const char *root, const char *name, int index) return ret;

[PATCH v9 5/9] kselftests: cgroup: don't fail on cg_kill_all() error in cg_destroy()

by Roman Gushchin

If the cgroup destruction races with an exit() of a belonging process(es), cg_kill_all() may fail. It's not a good reason to make cg_destroy() fail and leave the cgroup in place, potentially causing next test runs to fail.

[PATCH v4 1/2] Provide in-kernel headers for making it easy to extend the kernel

by Joel Fernandes (Google)

Introduce in-kernel headers and other artifacts which are made available as an archive through proc (/proc/kheaders.tar.xz file). This archive makes it possible to build kernel modules, run eBPF programs, and other tracing programs that need to extend the kernel for tracing purposes without any dependency on the file system having headers and build artifacts. On Android and embedded systems, it is common to switch kernels but not have kernel headers available on the file system. Raw kernel headers also cannot be copied into the filesystem like they can be on other distros, due to licensing and other issues. There's no linux-headers package on Android. Further once a different kernel is booted, any headers stored on the file system will no longer be useful. By storing the headers as a compressed archive within the kernel, we can avoid these issues that have been a hindrance for a long time. The feature is also buildable as a module just in case the user desires it not being part of the kernel image. This makes it possible to load and unload the headers on demand. A tracing program, or a kernel module builder can load the module, do its operations, and then unload the module to save kernel memory. The total memory needed is 3.8MB. The code to read the headers is based on /proc/config.gz code and uses the same technique to embed the headers. To build a module, the below steps have been tested on an x86 machine: modprobe kheaders rm -rf $HOME/headers mkdir -p $HOME/headers tar -xvf /proc/kheaders.tar.xz -C $HOME/headers >/dev/null cd my-kernel-module make -C $HOME/headers M=$(pwd) modules rmmod kheaders Additional notes: (1) external modules must be built on the same arch as the host that built vmlinux. This can be done either in a qemu emulated chroot on the target, or natively. This is due to host arch dependency of kernel scripts. (2) A limitation of module building with this is, since Module.symvers is not available in the archive due to a cyclic dependency with building of the archive into the kernel or module binaries, the modules built using the archive will not contain symbol versioning (modversion). This is usually not an issue since the idea of this patch is to build a kernel module on the fly and load it into the same kernel. An appropriate warning is already printed by the kernel to alert the user of modules not having modversions when built using the archive. For building with modversions, the user can use traditional header packages. For our tracing usecases, we build modules on the fly with this so it is not a concern. (3) I have left IKHD_ST and IKHD_ED markers as is to facilitate future patches that would extract the headers from a kernel or module image. Signed-off-by: Joel Fernandes (Google) <joel(a)joelfernandes.org> --- Changes since v3: - Blank tar was being generated because of a one line I forgot to push. It is updated now. - Added module.lds since arm64 needs it to build modules. Changes since v2: (Thanks to Masahiro Yamada for several excellent suggestions) - Added support for out of tree builds. - Added incremental build support bringing down build time of incremental builds from 50 seconds to 5 seconds. - Fixed various small nits / cleanups. - clean ups to kheaders.c pointed by Alexey Dobriyan. - Fixed MODULE_LICENSE in test module and kheaders.c - Dropped Module.symvers from archive due to circular dependency. Changes since v1: - removed IKH_EXTRA variable, not needed (Masahiro Yamada) - small fix ups to selftest - added target to main Makefile etc - added MODULE_LICENSE to test module - made selftest more quiet Changes since RFC: Both changes bring size down to 3.8MB: - use xz for compression - strip comments except SPDX lines - Call out the module name in Kconfig - Also added selftests in second patch to ensure headers are always working. Other notes: By the way I still see this error (without the patch) when doing a clean build: Makefile:594: include/config/auto.conf: No such file or directory It appears to be because of commit 0a16d2e8cb7e ("kbuild: use 'include' directive to load auto.conf from top Makefile") Documentation/dontdiff | 1 + init/Kconfig | 11 ++++++ kernel/.gitignore | 3 ++ kernel/Makefile | 37 +++++++++++++++++++ kernel/kheaders.c | 72 ++++++++++++++++++++++++++++++++++++ scripts/gen_ikh_data.sh | 78 +++++++++++++++++++++++++++++++++++++++ scripts/strip-comments.pl | 8 ++++ 7 files changed, 210 insertions(+) create mode 100644 kernel/kheaders.c create mode 100755 scripts/gen_ikh_data.sh create mode 100755 scripts/strip-comments.pl diff --git a/Documentation/dontdiff b/Documentation/dontdiff index 2228fcc8e29f..05a2319ee2a2 100644 --- a/Documentation/dontdiff +++ b/Documentation/dontdiff @@ -151,6 +151,7 @@ int8.c kallsyms kconfig keywords.c +kheaders_data.h* ksym.c* ksym.h* kxgettext diff --git a/init/Kconfig b/init/Kconfig index c9386a365eea..63ff0990ae55 100644 --- a/init/Kconfig +++ b/init/Kconfig @@ -563,6 +563,17 @@ config IKCONFIG_PROC This option enables access to the kernel configuration file through /proc/config.gz. +config IKHEADERS_PROC + tristate "Enable kernel header artifacts through /proc/kheaders.tar.xz" + select BUILD_BIN2C + depends on PROC_FS + help + This option enables access to the kernel header and other artifacts that + are generated during the build process.

[PATCH v4 0/8] selftests/kexec: add kexec tests

by Mimi Zohar

The kernel may be configured or an IMA policy specified on the boot command line requiring the kexec kernel image signature to be verified. At runtime a custom IMA policy may be loaded, replacing the policy specified on the boot command line. In addition, the arch specific policy rules are dynamically defined based on the secure boot mode that may require the kernel image signature to be verified. The kernel image may have a PE signature, an IMA signature, or both. In addition, there are two kexec syscalls - kexec_load and kexec_file_load - but only the kexec_file_load syscall can verify signatures. These kexec selftests verify that only properly signed kernel images are loaded as required, based on the kernel config, the secure boot mode, and the IMA runtime policy. Loading a kernel image or kernel module requires root privileges.

[PATCH v2] selftests/x86: Support Atom for syscall_arg_fault test

by Tong Bo

Atom-based CPUs trigger stack fault when invoke 32-bit SYSENTER instruction with invalid register values. So we also need SIGBUS handling in this case. Following is assembly when the fault exception happens. (gdb) disassemble $eip Dump of assembler code for function __kernel_vsyscall: 0xf7fd8fe0 <+0>: push %ecx 0xf7fd8fe1 <+1>: push %edx 0xf7fd8fe2 <+2>: push %ebp 0xf7fd8fe3 <+3>: mov %esp,%ebp 0xf7fd8fe5 <+5>: sysenter 0xf7fd8fe7 <+7>: int $0x80 => 0xf7fd8fe9 <+9>: pop %ebp 0xf7fd8fea <+10>: pop %edx 0xf7fd8feb <+11>: pop %ecx 0xf7fd8fec <+12>: ret End of assembler dump. According to Intel SDM, this could also be a Stack Segment Fault(#SS, 12), except a normal Page Fault(#PF, 14). Especially, in section 6.9 of Vol.3A, both stack and page faults are within the 10th(lowest priority) class, and as it said, "exceptions within each class are implementation-dependent and may vary from processor to processor". It's expected for processors like Intel Atom to trigger stack fault(SIGBUS), while we get page fault(SIGSEGV) from common Core processors.
