[RESEND PATCH v1 0/3] nolibc auxiliary vector retrieval support

by Ammar Faizi

From: Ammar Faizi <ammarfaizi2(a)gnuweeb.org> Hi Willy, This series is a follow up of our previous discussion about getauxval() and getpagesize() functions. It will apply cleanly on top of your "20221227-nolibc-weak-4" branch. Base commit: b6887ec8b0b0 ("tools/nolibc: add auxiliary vector retrieval for mips"). I have added a selftest for the getpagesize() function, but I am not sure how to assert the correctness of getauxval(). I think it is fine not to add a selftest for getauxval(). If you think we should, please give some advice on the test mechanism. Thanks!

[RFC PATCH v1 0/8] nolibc signal handling support

by Ammar Faizi

From: Ammar Faizi <ammarfaizi2(a)gnuweeb.org> Hi, This series adds signal handling support to the nolibc subsystem. 1) Initial implementation of nolibc sigaction(2) function. Currently, this implementation is only available on the x86-64 arch. sigaction() needs an architecture-dependent "signal trampoline" function that invokes the __rt_sigreturn syscall to resume the process after a signal gets handled. On Linux x86-64, the "signal trampoline" function has to be written in inline Assembly to prevent the compiler from controlling the %rsp (e.g., with -fno-omit-frame-pointer, every function has a pushq %rbp that makes the %rsp no longer point to struct rt_sigframe). The "signal trampoline" function is called __arch_restore_rt in this implementation. 2) signal(2) function. signal() function is the simpler version of sigaction(). Unlike sigaction(), which fully controls the struct sigaction, the caller only cares about the sa_handler when calling the signal() function. signal() internally calls sigaction(). This implementation is currently only available on the x86-64 arch. When the sigaction() function support is expanded to other architectures, this function will automatically support those architectures. It's basically just a sigaction() wrapper. 3) Extra nolibc updates. Apart from the signal handling support. This series also contains nolibc updates, they are: - getpagesize() support. - CFLAGS update. - fork(2) selftest. - sigaction(2) selftest. - signal(2) selftest. - getpagesize(2) selftest. There 8 patches in this series. It has been tested on Linux x86-64 arch and all tests OK. $ sudo ./nolibc-test Running test 'syscall' ... ... 66 wait_child = -1 ECHILD [OK] 67 waitpid_min = -1 ESRCH [OK] 68 waitpid_child = -1 ECHILD [OK] 69 write_badf = -1 EBADF [OK] 70 write_zero = 0 [OK] Errors during this test: 0 Running test 'stdlib' ... ... 14 memcmp_60_20 = 64 [OK] 15 memcmp_20_e0 = -192 [OK] 16 memcmp_e0_20 = 192 [OK] 17 memcmp_80_e0 = -96 [OK] 18 memcmp_e0_80 = 96 [OK] Errors during this test: 0 Total number of errors: 0 Exiting with status 0 $ make run -j8 Kernel: arch/x86/boot/bzImage is ready (#3) ... 82 test(s) passed.

[PATCH 0/3] selftests/tracing: Fix some testcases for recent change

by Masami Hiramatsu (Google)

This includes some patches to fix 2 issues on ftrace selftests. - eprobe filter and eprobe syntax test case were introduced but it doesn't check whether the kernel supports eprobe filter. Thus the new test case fails on the kernel which has eprobe but not support eprobe filter. To solve this issue, add a filter description to README file [1/3] and run the filter syntax error test only if the description is found in the README file [2/3]. - Recently objtool adds prefix symbols for the function padding nops, and the probepoint test case fails because this probepoint test case tests whether the kprobe event can probe the target function and the functions next to the target function. But the prefix symbols can not be probed. Thus these prefix symbols must be skipped [3/3]. Thank you, --- Masami Hiramatsu (Google) (3): tracing/eprobe: Fix to add filter on eprobe description in README file selftests/ftrace: Fix eprobe syntax test case to check filter support selftests/ftrace: Fix probepoint testcase to ignore __pfx_* symbols kernel/trace/trace.c | 2 +- .../test.d/dynevent/eprobes_syntax_errors.tc | 4 +++- .../selftests/ftrace/test.d/kprobe/probepoint.tc | 2 +- 3 files changed, 5 insertions(+), 3 deletions(-) -- Masami Hiramatsu (Google) <mhiramat(a)kernel.org>

[PATCH] proc: fix PIE proc-empty-vm, proc-pid-vm tests

by Alexey Dobriyan

vsyscall detection code uses direct call to the beginning of the vsyscall page: asm ("call %P0" :: "i" (0xffffffffff600000)) It generates "call rel32" instruction but it is not relocated if binary is PIE, so binary segfaults into random userspace address and vsyscall page status is detected incorrectly. Do more direct: asm ("call *%rax") which doesn't do need any relocaltions. Mark g_vsyscall as volatile for a good measure, I didn't find instruction setting it to 0. Now the code is obviously correct: xor eax, eax mov rdi, rbp mov rsi, rbp mov DWORD PTR [rip+0x2d15], eax # g_vsyscall = 0 mov rax, 0xffffffffff600000 call rax mov DWORD PTR [rip+0x2d02], 1 # g_vsyscall = 1 mov eax, DWORD PTR ds:0xffffffffff600000 mov DWORD PTR [rip+0x2cf1], 2 # g_vsyscall = 2 mov edi, [rip+0x2ceb] # exit(g_vsyscall) call exit Note: fixed proc-empty-vm test oopses 5.19.0-28-generic kernel but this is separate story.

The "bug" is that "call rel32" instruction testing for executable vsyscall page which should be relocated to "call 0xffffffffff600000" is messed up. Ubuntu 22.10 ships with "vsyscall=xonly" so there should not be any faults when executing from it. But segfault happens with normal randomised userspace address. I'll change it to "call *rax" which should be more robust (and works) and free from relocations.

[PATCH v3 2/2] selftests/kexec: enable lockdown tests

[PATCH v4 0/7] kselftest/alsa: pcm-test improvements

by Mark Brown

This series provides a bunch of quick updates which should make the coverage from pcm-test a bit more useful, it adds some support for skipping tests when the hardware/driver is unable to support the requested configuration, support for providing user visible descriptions and then expands the set of cases we cover to include more sample rates and channel counts. This should exercise switching between 8kHz and 44.1kHz based rates and ensure that clocking doesn't get confused by non-stereo channel counts, both of which are I expect common real world errors, at least for embedded cards. v4: - Rebase onto v6.2-rc1. v3: - "Rebase" onto Takashi's current tree (with a revert). - Include Jaroslav's changes to specify all tests in the configuration file parsing. - Add a new "description" field to the configuration instead of trying to name the tests. - Always run both default and per-system tests, logging our success at setting the per-system configurations as a separate test since they shouldn't fail. v2: - Rebase onto Takashi's current tree. - Tweak the buffer sizes for the newly added cases, don't be quite so ambitious in how big a buffer we request for 96kHz and don't go quite so small for 8kHz since some devices start hitting lower limits on period size and struggle to deliver accurate timing.

[PATCH v4] selftest/vm: add mremap expand merge offset test

by Lorenzo Stoakes

Add a test to assert that we can mremap() and expand a mapping starting from an offset within an existing mapping. We unmap the last page in a 3 page mapping to ensure that the remap should always succeed, before remapping from the 2nd page. This is additionally a regression test for the issue solved in "mm, mremap: fix mremap() expanding vma with addr inside vma" and confirmed to fail prior to the change and pass after it. Finally, this patch updates the existing mremap expand merge test to check error conditions and reduce code duplication between the two tests.

[PATCH] selftest/vm: add mremap expand merge offset test

by Lorenzo Stoakes

Add a test to assert that we can mremap() and expand a mapping starting from an offset within an existing mapping. We unmap the last page in a 3 page mapping to ensure that the remap should always succeed, before remapping from the 2nd page. This is additionally a regression test for the issue solved in "mm, mremap: fix mremap() expanding vma with addr inside vma" and confirmed to fail prior to the change and pass after it. Finally, this patch updates the existing mremap expand merge test to check error conditions and reduce code duplication between the two tests.

[PATCH] selftests: net: fix cmsg_so_mark.sh test hang

by Po-Hsu Lin

This cmsg_so_mark.sh test will hang on non-amd64 systems because of the infinity loop for argument parsing in cmsg_sender. Variable "o" in cs_parse_args() for taking getopt() should be an int, otherwise it will be 255 when getopt() returns -1 on non-amd64 system and thus causing infinity loop.

[PATCH 5.15 0/2] Fix kvm selftest build failures in linux-5.15.y

by Tyler Hicks

From: "Tyler Hicks" <code(a)tyhicks.com> The backport of commit 05c2224d4b04 ("KVM: selftests: Fix number of pages for memory slot in memslot_modification_stress_test") broke the build of the KVM selftest memslot_modification_stress_test.c source file in two ways: - Incorrectly assumed that max_t() was defined despite commit 5cf67a6051ea ("tools/include: Add _RET_IP_ and math definitions to kernel.h") not being present - Incorrectly assumed that kvm_vm struct members could be directly accessed despite b530eba14c70 ("KVM: selftests: Get rid of kvm_util_internal.h") not being present Backport the first commit, as it is simple enough. Work around the lack of the second commit by using the accessors to get to the kvm_vm struct members. Note that the linux-6.0.y backport of commit 05c2224d4b04 ("KVM: selftests: Fix number of pages for memory slot in memslot_modification_stress_test") is fine because the two prerequisite commits, mentioned above, are both present in v6.0.

[PATCH bpf-next v3 00/16] bpfilter

by Quentin Deslandes

The patchset is based on the patches from David S. Miller [1], Daniel Borkmann [2], and Dmitrii Banshchikov [3]. The main goal of the patchset is to prepare bpfilter for iptables' configuration blob parsing and code generation. The patchset introduces data structures and code for matches, targets, rules and tables. Beside that the code generation is introduced. The first version of the code generation supports only "inline" mode - all chains and their rules emit instructions in linear approach. Things that are not implemented yet: 1) The process of switching from the previous BPF programs to the new set isn't atomic. 2) No support of device ifindex - it's hardcoded 3) No helper subprog for counters update Another problem is using iptables' blobs for tests and filter table initialization. While it saves lines something more maintainable should be done here. The plan for the next iteration: 1) Add a helper program for counters update 2) Handle ifindex Patches 1/2 adds definitions of the used types. Patch 3 adds logging to bpfilter. Patch 4 adds an associative map. Patch 5 add runtime context structure. Patches 6/7 add code generation infrastructure and TC code generator. Patches 8/9/10/11/12 add code for matches, targets, rules and table. Patch 13 adds code generation for table. Patch 14 handles hooked setsockopt(2) calls. Patch 15 adds filter table Patch 16 uses prepared code in main(). Due to poor hardware availability on my side, I've not been able to benchmark those changes. I plan to get some numbers for the next iteration. FORWARD filter chain is now supported, however, it's attached to TC INGRESS along with INPUT filter chain. This is due to XDP not supporting multiple programs to be attached. I could generate a single program out of both INPUT and FORWARD chains, but that would prevent another BPF program to be attached to the interface anyway. If a solution exists to attach both those programs to XDP while allowing for other programs to be attached, it requires more investigation. In the meantime, INPUT and FORWARD filtering is supported using TC. Most of the code in this series was written by Dmitrii Banshchikov, my changes are limited to v3. I've tried to reflect this fact in the commits by adding 'Co-developed-by:' and 'Signed-off-by:' for Dmitrii, please tell me this was done the wrong way. v2 -> v3 Chains: * Add support for FORWARD filter chain. * Add generation of BPF bytecode to assess whether a packet should be forwarded or not, using bpf_fib_lookup(). * Allow for multiple programs to be attached to TC. * Allow for multiple TC hooks to be used. Code generation: * Remove duplicated BPF bytecode generation. * Fix a bug regarding jump offset during generation. * Remove support for XDP from the series, as it's not currently used. Table: * Add new filter_table_update_counters() virtual call. It updates the table's counter stored in the ipt_entry structure. This way, when iptables tries to fetch the values of the counters, bpfilter only has to copy the ipt_entry cached in the table structure. Logging: * Refactor logging primitives. Sockopts: * Add support for userspace counters querying. Rule: * Store the rule's index inside struct rule, to each counters' map usage. v1 -> v2 Maps: * Use map_upsert instead of separate map_insert and map_update Matches: * Add a new virtual call - gen_inline. The call is used for * inline generating of a rule's match. Targets: * Add a new virtual call - gen_inline. The call is used for inline generating of a rule's target. Rules: * Add code generation for rules Table: * Add struct table_ops * Add map for table_ops * Add filter table * Reorganize the way filter table is initialized Sockopts: * Install/uninstall BPF programs while handling IPT_SO_SET_REPLACE Code generation: * Add first version of the code generation Dependencies: * Add libbpf v0 -> v1 IO: * Use ssize_t in pvm_read, pvm_write for total_bytes * Move IO functions into sockopt.c and main.c Logging: * Use LOGLEVEL_EMERG, LOGLEVEL_NOTICE, LOGLEVE_DEBUG while logging to /dev/kmsg * Prepend log message with <n> where n is log level * Conditionally enable BFLOG_DEBUG messages * Merge bflog.{h,c} into context.h Matches: * Reorder fields in struct match_ops for tight packing * Get rid of struct match_ops_map * Rename udp_match_ops to xt_udp * Use XT_ALIGN macro * Store payload size in match size * Move udp match routines into a separate file Targets: * Reorder fields in struct target_ops for tight packing * Get rid of struct target_ops_map * Add comments for convert_verdict function Rules: * Add validation Tables: * Combine table_map and table_list into table_index * Add validation Sockopts: * Handle IPT_SO_GET_REVISION_TARGET 1. https://lore.kernel.org/patchwork/patch/902785/ 2. https://lore.kernel.org/patchwork/patch/902783/ 3. https://kernel.ubuntu.com/~cking/stress-ng/stress-ng.pdf Quentin Deslandes (16): bpfilter: add types for usermode helper tools: add bpfilter usermode helper header bpfilter: add logging facility bpfilter: add map container bpfilter: add runtime context bpfilter: add BPF bytecode generation infrastructure bpfilter: add support for TC bytecode generation bpfilter: add match structure bpfilter: add support for src/dst addr and ports bpfilter: add target structure bpfilter: add rule structure bpfilter: add table structure bpfilter: add table code generation bpfilter: add setsockopt() support bpfilter: add filter table bpfilter: handle setsockopt() calls include/uapi/linux/bpfilter.h | 154 +++ net/bpfilter/Makefile | 16 +- net/bpfilter/codegen.c | 1040 +++++++++++++++++ net/bpfilter/codegen.h | 183 +++ net/bpfilter/context.c | 168 +++ net/bpfilter/context.h | 24 + net/bpfilter/filter-table.c | 344 ++++++ net/bpfilter/filter-table.h | 18 + net/bpfilter/logger.c | 52 + net/bpfilter/logger.h | 80 ++ net/bpfilter/main.c | 132 ++- net/bpfilter/map-common.c | 51 + net/bpfilter/map-common.h | 19 + net/bpfilter/match.c | 55 + net/bpfilter/match.h | 37 + net/bpfilter/rule.c | 286 +++++ net/bpfilter/rule.h | 37 + net/bpfilter/sockopt.c | 533 +++++++++ net/bpfilter/sockopt.h | 15 + net/bpfilter/table.c | 391 +++++++ net/bpfilter/table.h | 59 + net/bpfilter/target.c | 203 ++++ net/bpfilter/target.h | 57 + net/bpfilter/xt_udp.c | 111 ++ tools/include/uapi/linux/bpfilter.h | 175 +++ .../testing/selftests/bpf/bpfilter/.gitignore | 8 + tools/testing/selftests/bpf/bpfilter/Makefile | 57 + .../selftests/bpf/bpfilter/bpfilter_util.h | 80 ++ .../selftests/bpf/bpfilter/test_codegen.c | 338 ++++++ .../testing/selftests/bpf/bpfilter/test_map.c | 63 + .../selftests/bpf/bpfilter/test_match.c | 69 ++ .../selftests/bpf/bpfilter/test_rule.c | 56 + .../selftests/bpf/bpfilter/test_target.c | 83 ++ .../selftests/bpf/bpfilter/test_xt_udp.c | 48 + 34 files changed, 4999 insertions(+), 43 deletions(-) create mode 100644 net/bpfilter/codegen.c create mode 100644 net/bpfilter/codegen.h create mode 100644 net/bpfilter/context.c create mode 100644 net/bpfilter/context.h create mode 100644 net/bpfilter/filter-table.c create mode 100644 net/bpfilter/filter-table.h create mode 100644 net/bpfilter/logger.c create mode 100644 net/bpfilter/logger.h create mode 100644 net/bpfilter/map-common.c create mode 100644 net/bpfilter/map-common.h create mode 100644 net/bpfilter/match.c create mode 100644 net/bpfilter/match.h create mode 100644 net/bpfilter/rule.c create mode 100644 net/bpfilter/rule.h create mode 100644 net/bpfilter/sockopt.c create mode 100644 net/bpfilter/sockopt.h create mode 100644 net/bpfilter/table.c create mode 100644 net/bpfilter/table.h create mode 100644 net/bpfilter/target.c create mode 100644 net/bpfilter/target.h create mode 100644 net/bpfilter/xt_udp.c create mode 100644 tools/include/uapi/linux/bpfilter.h create mode 100644 tools/testing/selftests/bpf/bpfilter/.gitignore create mode 100644 tools/testing/selftests/bpf/bpfilter/Makefile create mode 100644 tools/testing/selftests/bpf/bpfilter/bpfilter_util.h create mode 100644 tools/testing/selftests/bpf/bpfilter/test_codegen.c create mode 100644 tools/testing/selftests/bpf/bpfilter/test_map.c create mode 100644 tools/testing/selftests/bpf/bpfilter/test_match.c create mode 100644 tools/testing/selftests/bpf/bpfilter/test_rule.c create mode 100644 tools/testing/selftests/bpf/bpfilter/test_target.c create mode 100644 tools/testing/selftests/bpf/bpfilter/test_xt_udp.c -- 2.38.1

[V3 PATCH 0/2] Execute hypercalls from guests according to cpu

by Vishal Annapurve

Confidential VMs(CVMs) need to execute hypercall instruction as per the CPU type. Normally KVM emulates the vmcall/vmmcall instruction by patching the guest code at runtime. Such a guest memory manipulation by KVM is not allowed with CVMs. This series adds support of executing hypercall as per the native cpu type queried using cpuid instruction. CPU vendor type is stored after one time execution of cpuid instruction to be reused later. Changes in v3: 1) Guest logic is modified to not rely on host cpu type and instead query cpu vendor using cpuid instruction. 2) Existing callers of vmmcall/vmcall are not updated to avoid enforcing native hypercall instruction across all users which are mostly non-confidential usecases. v2: https://lore.kernel.org/all/20220915000448.1674802-1-vannapurve@google.com/ More discussion around this change: https://lore.kernel.org/lkml/Y1Hhw40H58EmZ6lK@google.com/ Vishal Annapurve (2): KVM: selftests: x86: Cache the cpu vendor type KVM: selftests: x86: Add native hypercall support .../selftests/kvm/include/x86_64/processor.h | 3 ++ .../selftests/kvm/lib/x86_64/processor.c | 51 +++++++++++++++++-- 2 files changed, 49 insertions(+), 5 deletions(-) -- 2.39.0.314.g84b9a713c41-goog

[PATCH v6 0/6] mm/memfd: introduce MFD_NOEXEC_SEAL and MFD_EXEC

by jeffxu＠chromium.org

From: Jeff Xu <jeffxu(a)google.com> Since Linux introduced the memfd feature, memfd have always had their execute bit set, and the memfd_create() syscall doesn't allow setting it differently. However, in a secure by default system, such as ChromeOS, (where all executables should come from the rootfs, which is protected by Verified boot), this executable nature of memfd opens a door for NoExec bypass and enables “confused deputy attack”. E.g, in VRP bug [1]: cros_vm process created a memfd to share the content with an external process, however the memfd is overwritten and used for executing arbitrary code and root escalation. [2] lists more VRP in this kind. On the other hand, executable memfd has its legit use, runc uses memfd’s seal and executable feature to copy the contents of the binary then execute them, for such system, we need a solution to differentiate runc's use of executable memfds and an attacker's [3]. To address those above, this set of patches add following: 1> Let memfd_create() set X bit at creation time. 2> Let memfd to be sealed for modifying X bit. 3> A new pid namespace sysctl: vm.memfd_noexec to control the behavior of X bit.For example, if a container has vm.memfd_noexec=2, then memfd_create() without MFD_NOEXEC_SEAL will be rejected. 4> A new security hook in memfd_create(). This make it possible to a new LSM, which rejects or allows executable memfd based on its security policy. This is V6 version of patch: see [4] [5] [6] [7] for previous versions.

[PATCH 0/2] sched/membarrier, selftests: Introduce MEMBARRIER_CMD_GET_REGISTRATIONS

by Michal Clapinski

This change provides a method to query previously issued registrations. It's needed for CRIU (checkpoint/restore in userspace). Before this change we had to issue private membarrier commands during checkpoint - if they succeeded, they must have been registered. Unfortunately global membarrier succeeds even on unregistered processes, so there was no way to tell if MEMBARRIER_CMD_REGISTER_GLOBAL_EXPEDITED had been issued or not. CRIU is run after the process has been frozen with ptrace, so we don't have to worry too much about the result of running this command in parallel with registration commands.

[V3 PATCH 0/8] KVM: selftests: SEV: selftests for fd-based private memory

by Vishal Annapurve

This series implements selftests executing SEV VMs to target the feature implemented by Chao via: https://lore.kernel.org/lkml/20221220074318.GC1724933@chaop.bj.intel.com/T/ Below changes aim to test the fd based approach for guest private memory in context of SEV VMs executing on AMD SEV compatible platforms. sev_private_mem_test.c file adds selftest to access private memory from the guest via private/shared accesses and checking if the contents can be leaked to/accessed by vmm via shared memory view before/after conversions. To allow SEV/SEV-ES VMs to toggle the encryption bit during memory conversion, support is added for mapping guest pagetables to guest va ranges and passing the mapping information to guests via shared pages. Updates in v3: 1) Dropped RFC tag. 2) Pagetable mapping logic is revisited to reduce the APIs and passing the information to guest is simplified. 3) Additional changes to execute hypercall as per cpu type are added 4) Selftest implementation is based on revised non-confidential VM selftests. Link to RFC v2: https://lore.kernel.org/lkml/20220830224259.412342-8-vannapurve@google.com/… This series has dependency on following patch series: 1) Series mentioned above from Chao 2) Selftests testing fd based memory for non-confidential VMs: https://lore.kernel.org/lkml/20221205232341.4131240-5-vannapurve@google.com… 3) Selftests to add SEV VM creation and execution from Peter and Michael: https://lore.kernel.org/lkml/20221018205845.770121-3-pgonda@google.com/T/ 4) Series to execute hypercall natively: https://lore.kernel.org/lkml/20221222230458.3828342-1-vannapurve@google.com/ Github link for the patches posted as part of this series: https://github.com/vishals4gh/linux/commits/sev_upm_selftests_rfc_v3 Vishal Annapurve (8): KVM: selftests: private_mem: Use native hypercall KVM: selftests: Support mapping pagetables to guest virtual memory KVM: selftests: x86: Support changing gpa encryption masks KVM: selftests: Split SEV VM creation logic KVM: selftests: Enable pagetable mapping for SEV VMs KVM: selftests: Refactor private_mem_test KVM: selftests: private_mem_test: Add support for SEV VMs KVM: selftests: Add private mem test for SEV VMs tools/testing/selftests/kvm/.gitignore | 1 + tools/testing/selftests/kvm/Makefile | 2 + .../selftests/kvm/include/kvm_util_base.h | 88 +++++++ .../include/x86_64/private_mem_test_helper.h | 18 ++ .../selftests/kvm/include/x86_64/processor.h | 4 + .../selftests/kvm/include/x86_64/sev.h | 4 + tools/testing/selftests/kvm/lib/kvm_util.c | 88 ++++++- .../selftests/kvm/lib/x86_64/private_mem.c | 2 +- .../kvm/lib/x86_64/private_mem_test_helper.c | 228 ++++++++++++++++++ .../selftests/kvm/lib/x86_64/processor.c | 80 ++++++ tools/testing/selftests/kvm/lib/x86_64/sev.c | 25 +- .../selftests/kvm/x86_64/private_mem_test.c | 187 +------------- .../kvm/x86_64/sev_private_mem_test.c | 26 ++ 13 files changed, 562 insertions(+), 191 deletions(-) create mode 100644 tools/testing/selftests/kvm/include/x86_64/private_mem_test_helper.h create mode 100644 tools/testing/selftests/kvm/lib/x86_64/private_mem_test_helper.c create mode 100644 tools/testing/selftests/kvm/x86_64/sev_private_mem_test.c -- 2.39.0.314.g84b9a713c41-goog

[PATCH 2/2] tracing/selftests: Add test for event filtering on function name

by Steven Rostedt

From: "Steven Rostedt (Google)" <rostedt(a)goodmis.org> With the new filter logic of passing in the name of a function to match an instruction pointer (or the address of the function), add a test to make sure that it is functional. This is also the first test to test plain filtering. The filtering has been tested via the trigger logic, which uses the same code, but there was nothing to test just the event filter, so this test is the first to add such a case.

[PATCH bpf-next 1/2] bpf: Add flag BPF_F_NO_TUNNEL_KEY to bpf_skb_set_tunnel_key()

by Christian Ehrig

This patch allows to remove TUNNEL_KEY from the tunnel flags bitmap when using bpf_skb_set_tunnel_key by providing a BPF_F_NO_TUNNEL_KEY flag. On egress, the resulting tunnel header will not contain a tunnel key if the protocol and implementation supports it. At the moment bpf_tunnel_key wants a user to specify a numeric tunnel key. This will wrap the inner packet into a tunnel header with the key bit and value set accordingly. This is problematic when using a tunnel protocol that supports optional tunnel keys and a receiving tunnel device that is not expecting packets with the key bit set. The receiver won't decapsulate and drop the packet. RFC 2890 and RFC 2784 GRE tunnels are examples where this flag is useful.
