[PATCH AUTOSEL 5.16 16/34] selftests: fixup build warnings in pidfd / clone3 tests

by Sasha Levin

From: Axel Rasmussen <axelrasmussen(a)google.com> [ Upstream commit e2aa5e650b07693477dff554053605976789fd68 ] These are some trivial fixups, which were needed to build the tests with clang and -Werror. The following issues are fixed: - Remove various unused variables. - In child_poll_leader_exit_test, clang isn't smart enough to realize syscall(SYS_exit, 0) won't return, so it complains we never return from a non-void function. Add an extra exit(0) to appease it. - In test_pidfd_poll_leader_exit, ret may be branched on despite being uninitialized, if we have !use_waitpid. Initialize it to zero to get the right behavior in that case.

[PATCH AUTOSEL 5.16 15/34] pidfd: fix test failure due to stack overflow on some arches

by Sasha Levin

From: Axel Rasmussen <axelrasmussen(a)google.com> [ Upstream commit 4cbd93c3c110447adc66cb67c08af21f939ae2d7 ] When running the pidfd_fdinfo_test on arm64, it fails for me. After some digging, the reason is that the child exits due to SIGBUS, because it overflows the 1024 byte stack we've reserved for it. To fix the issue, increase the stack size to 8192 bytes (this number is somewhat arbitrary, and was arrived at through experimentation -- I kept doubling until the failure no longer occurred). Also, let's make the issue easier to debug. wait_for_pid() returns an ambiguous value: it may return -1 in all of these cases: 1. waitpid() itself returned -1 2. waitpid() returned success, but we found !WIFEXITED(status). 3. The child process exited, but it did so with a -1 exit code. There's no way for the caller to tell the difference. So, at least log which occurred, so the test runner can debug things. While debugging this, I found that we had !WIFEXITED(), because the child exited due to a signal. This seems like a reasonably common case, so also print out whether or not we have WIFSIGNALED(), and the associated WTERMSIG() (if any). This lets us see the SIGBUS I'm fixing clearly when it occurs. Finally, I'm suspicious of allocating the child's stack on our stack. man clone(2) suggests that the correct way to do this is with mmap(), and in particular by setting MAP_STACK. So, switch to doing it that way instead.

[PATCH] ima: Calculate digest in ima_inode_hash() if not available

by Roberto Sassu

__ima_inode_hash() checks if a digest has been already calculated by looking for the integrity_iint_cache structure associated to the passed inode. Users of ima_file_hash() and ima_inode_hash() (e.g. eBPF) might be interested in obtaining the information without having to setup an IMA policy so that the digest is always available at the time they call one of those functions. Open a new file descriptor in __ima_inode_hash(), so that this function could invoke ima_collect_measurement() to calculate the digest if it is not available. Still return -EOPNOTSUPP if the calculation failed. Instead of opening a new file descriptor, the one from ima_file_hash() could have been used. However, since ima_inode_hash() was created to obtain the digest when the file descriptor is not available, it could benefit from this change too. Also, the opened file descriptor might be not suitable for use (file descriptor opened not for reading). This change does not cause memory usage increase, due to using a temporary integrity_iint_cache structure for the digest calculation, and due to freeing the ima_digest_data structure inside integrity_iint_cache before exiting from __ima_inode_hash(). Finally, update the test by removing ima_setup.sh (it is not necessary anymore to set an IMA policy) and by directly executing /bin/true.

[PATCH V2] selftests: Use -isystem instead of -I to include headers

by Muhammad Usama Anjum

Selftests need kernel headers and glibc for compilation. In compilation of selftests, uapi headers from kernel source are used instead of default ones while glibc has already been compiled with different header files installed in the operating system. So there can be redefination warnings from compiler. These warnings can be suppressed by using -isystem to include the uapi headers.

[PATCH V2 0/2] selftests: sgx: Fix build of test_sgx

by Muhammad Usama Anjum

CC can have multiple sub-strings like "ccache gcc". Build system of sgx selftest is unable to support this use case and test_sgx isn't built. Then rsync gives an erorr: rsync: [sender] link_stat "//linux/build/kselftest/sgx/test_sgx" failed: No such file or directory (2) rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1333) [sender=3.2.3] This can be fixed if CC is considered to have one string while passing to check_cc.sh script and inside this script, CC is expanded before execution. Following build tests have been performed to confirm that these patches don't break anything else. The verification has also been done through KernelCI scripts locally as KernelCI has caught this bug: 1) cd tools/testing/selftests && make 2) make -C tools/testing/selftests 3) make -C tools/testing/selftests O=build 4) make -C tools/testing/selftests O=build CC="ccache gcc" 5) ./kci_build make_kselftest Muhammad Usama Anjum (2): selftests: x86: add validity check and allow field splitting selftests: sgx: Treat CC as one argument tools/testing/selftests/sgx/Makefile | 2 +- tools/testing/selftests/x86/check_cc.sh | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) -- 2.30.2

[PATCH v5 1/6] kunit: Introduce _NULL and _NOT_NULL macros

Today, when we want to check if a pointer is NULL and not ERR we have two options: KUNIT_EXPECT_TRUE(test, ptr == NULL); or KUNIT_EXPECT_PTR_NE(test, ptr, (struct mystruct *)NULL); Create a new set of macros that take care of NULL checks.

[PATCH v3] selftests/ftrace: Do not trace do_softirq because of PREEMPT_RT

by Krzysztof Kozlowski

The PREEMPT_RT patchset does not use do_softirq() function thus trying to filter for do_softirq fails for such kernel: echo do_softirq ftracetest: 81: echo: echo: I/O error Choose some other visible function for the test. The function does not have to be actually executed during the test, because it is only testing filter API interface.

[PATCH] selftests: Use -isystem instead of -I to include headers

by Muhammad Usama Anjum

Selftests need kernel headers and glibc for compilation. In compilation of selftests, uapi headers from kernel source are used instead of default ones while glibc has already been compiled with different header files installed in the operating system. So there can be redefination warnings from compiler. These warnings can be suppressed by using -isystem to include the uapi headers.

[PATCH net-next] ipv6: Reject routes configurations that specify dsfield (tos)

by Guillaume Nault

The ->rtm_tos option is normally used to route packets based on both the destination address and the DS field. However it's ignored for IPv6 routes. Setting ->rtm_tos for IPv6 is thus invalid as the route is going to work only on the destination address anyway, so it won't behave as specified. Suggested-by: Toke Høiland-Jørgensen <toke(a)redhat.com> Signed-off-by: Guillaume Nault <gnault(a)redhat.com> --- The same problem exists for ->rtm_scope. I'm working only on ->rtm_tos here because IPv4 recently started to validate this option too (as part of the DSCP/ECN clarification effort). I'll give this patch some soak time, then send another one for rejecting ->rtm_scope in IPv6 routes if nobody complains. net/ipv6/route.c | 6 ++++++ tools/testing/selftests/net/fib_tests.sh | 13 +++++++++++++ 2 files changed, 19 insertions(+) diff --git a/net/ipv6/route.c b/net/ipv6/route.c index f4884cda13b9..dd98a11fbdb6 100644 --- a/net/ipv6/route.c +++ b/net/ipv6/route.c @@ -5009,6 +5009,12 @@ static int rtm_to_fib6_config(struct sk_buff *skb, struct nlmsghdr *nlh, err = -EINVAL; rtm = nlmsg_data(nlh); + if (rtm->rtm_tos) { + NL_SET_ERR_MSG(extack, + "Invalid dsfield (tos): option not available for IPv6"); + goto errout; + } + *cfg = (struct fib6_config){ .fc_table = rtm->rtm_table, .fc_dst_len = rtm->rtm_dst_len, diff --git a/tools/testing/selftests/net/fib_tests.sh b/tools/testing/selftests/net/fib_tests.sh index bb73235976b3..e2690cc42da3 100755 --- a/tools/testing/selftests/net/fib_tests.sh +++ b/tools/testing/selftests/net/fib_tests.sh @@ -988,12 +988,25 @@ ipv6_rt_replace() ipv6_rt_replace_mpath } +ipv6_rt_dsfield() +{ + echo + echo "IPv6 route with dsfield tests" + + run_cmd "$IP -6 route flush 2001:db8:102::/64" + + # IPv6 doesn't support routing based on dsfield + run_cmd "$IP -6 route add 2001:db8:102::/64 dsfield 0x04 via 2001:db8:101::2" + log_test $? 2 "Reject route with dsfield" +} + ipv6_route_test() { route_setup ipv6_rt_add ipv6_rt_replace + ipv6_rt_dsfield route_cleanup } -- 2.21.3

[PATCH v4 1/6] kunit: Introduce _NULL and _NOT_NULL macros

by Ricardo Ribalda

Today, when we want to check if a pointer is NULL and not ERR we have two options: KUNIT_EXPECT_TRUE(test, ptr == NULL); or KUNIT_EXPECT_PTR_NE(test, ptr, (struct mystruct *)NULL); Create a new set of macros that take care of NULL checks.

[PATCH AUTOSEL 4.9 3/7] selftests/zram01.sh: Fix compression ratio calculation

From: Yang Xu <xuyang2018.jy(a)fujitsu.com> [ Upstream commit d18da7ec3719559d6e74937266d0416e6c7e0b31 ] zram01 uses `free -m` to measure zram memory usage. The results are no sense because they are polluted by all running processes on the system. We Should only calculate the free memory delta for the current process. So use the third field of /sys/block/zram<id>/mm_stat to measure memory usage instead. The file is available since kernel 4.1. orig_data_size(first): uncompressed size of data stored in this disk. compr_data_size(second): compressed size of data stored in this disk mem_used_total(third): the amount of memory allocated for this disk Also remove useless zram cleanup call in zram_fill_fs and so we don't need to cleanup zram twice if fails.

[PATCH AUTOSEL 4.14 3/8] selftests/zram01.sh: Fix compression ratio calculation

by Sasha Levin

From: Yang Xu <xuyang2018.jy(a)fujitsu.com> [ Upstream commit d18da7ec3719559d6e74937266d0416e6c7e0b31 ] zram01 uses `free -m` to measure zram memory usage. The results are no sense because they are polluted by all running processes on the system. We Should only calculate the free memory delta for the current process. So use the third field of /sys/block/zram<id>/mm_stat to measure memory usage instead. The file is available since kernel 4.1. orig_data_size(first): uncompressed size of data stored in this disk. compr_data_size(second): compressed size of data stored in this disk mem_used_total(third): the amount of memory allocated for this disk Also remove useless zram cleanup call in zram_fill_fs and so we don't need to cleanup zram twice if fails.

[PATCH AUTOSEL 4.14 2/8] selftests/zram: Skip max_comp_streams interface on newer kernel

by Sasha Levin

From: Yang Xu <xuyang2018.jy(a)fujitsu.com> [ Upstream commit fc4eb486a59d70bd35cf1209f0e68c2d8b979193 ] Since commit 43209ea2d17a ("zram: remove max_comp_streams internals"), zram has switched to per-cpu streams. Even kernel still keep this interface for some reasons, but writing to max_comp_stream doesn't take any effect. So skip it on newer kernel ie 4.7.

[PATCH AUTOSEL 4.19 04/10] selftests/zram: Adapt the situation that /dev/zram0 is being used

by Sasha Levin

From: Yang Xu <xuyang2018.jy(a)fujitsu.com> [ Upstream commit 01dabed20573804750af5c7bf8d1598a6bf7bf6e ] If zram-generator package is installed and works, then we can not remove zram module because zram swap is being used. This case needs a clean zram environment, change this test by using hot_add/hot_remove interface. So even zram device is being used, we still can add zram device and remove them in cleanup. The two interface was introduced since kernel commit 6566d1a32bf7("zram: add dynamic device add/remove functionality") in v4.2-rc1.

[PATCH AUTOSEL 5.4 06/15] selftests/zram: Adapt the situation that /dev/zram0 is being used

by Sasha Levin

From: Yang Xu <xuyang2018.jy(a)fujitsu.com> [ Upstream commit 01dabed20573804750af5c7bf8d1598a6bf7bf6e ] If zram-generator package is installed and works, then we can not remove zram module because zram swap is being used. This case needs a clean zram environment, change this test by using hot_add/hot_remove interface. So even zram device is being used, we still can add zram device and remove them in cleanup. The two interface was introduced since kernel commit 6566d1a32bf7("zram: add dynamic device add/remove functionality") in v4.2-rc1. If kernel supports these two interface, we use hot_add/hot_remove to slove this problem, if not, just check whether zram is being used or built in, then skip it on old kernel.

[PATCH AUTOSEL 5.4 02/15] selftests: rtc: Increase test timeout so that all tests run

by Sasha Levin

From: Nícolas F. R. A. Prado <nfraprado(a)collabora.com> [ Upstream commit f034cc1301e7d83d4ec428dd6b8ffb57ca446efb ] The timeout setting for the rtc kselftest is currently 90 seconds. This setting is used by the kselftest runner to stop running a test if it takes longer than the assigned value. However, two of the test cases inside rtc set alarms. These alarms are set to the next beginning of the minute, so each of these test cases may take up to, in the worst case, 60 seconds. In order to allow for all test cases in rtc to run, even in the worst case, when using the kselftest runner, the timeout value should be increased to at least 120. Set it to 180, so there's some additional slack. Correct operation can be tested by running the following command right after the start of a minute (low second count), and checking that all test cases run: ./run_kselftest.sh -c rtc Signed-off-by: Nícolas F.

[PATCH AUTOSEL 5.10 08/27] selftests/zram: Adapt the situation that /dev/zram0 is being used

by Sasha Levin

From: Yang Xu <xuyang2018.jy(a)fujitsu.com> [ Upstream commit 01dabed20573804750af5c7bf8d1598a6bf7bf6e ] If zram-generator package is installed and works, then we can not remove zram module because zram swap is being used. This case needs a clean zram environment, change this test by using hot_add/hot_remove interface. So even zram device is being used, we still can add zram device and remove them in cleanup. The two interface was introduced since kernel commit 6566d1a32bf7("zram: add dynamic device add/remove functionality") in v4.2-rc1. If kernel supports these two interface, we use hot_add/hot_remove to slove this problem, if not, just check whether zram is being used or built in, then skip it on old kernel.

[PATCH AUTOSEL 5.10 07/27] selftests/zram01.sh: Fix compression ratio calculation

From: Yang Xu <xuyang2018.jy(a)fujitsu.com> [ Upstream commit d18da7ec3719559d6e74937266d0416e6c7e0b31 ] zram01 uses `free -m` to measure zram memory usage. The results are no sense because they are polluted by all running processes on the system. We Should only calculate the free memory delta for the current process. So use the third field of /sys/block/zram<id>/mm_stat to measure memory usage instead. The file is available since kernel 4.1. orig_data_size(first): uncompressed size of data stored in this disk. compr_data_size(second): compressed size of data stored in this disk mem_used_total(third): the amount of memory allocated for this disk Also remove useless zram cleanup call in zram_fill_fs and so we don't need to cleanup zram twice if fails.

From: Yang Xu <xuyang2018.jy(a)fujitsu.com> [ Upstream commit fc4eb486a59d70bd35cf1209f0e68c2d8b979193 ] Since commit 43209ea2d17a ("zram: remove max_comp_streams internals"), zram has switched to per-cpu streams. Even kernel still keep this interface for some reasons, but writing to max_comp_stream doesn't take any effect. So skip it on newer kernel ie 4.7. The code that comparing kernel version is from xfstests testsuite ext4/053.

[PATCH AUTOSEL 5.10 04/27] kselftest: signal all child processes

by Sasha Levin

From: Li Zhijian <lizhijian(a)cn.fujitsu.com> [ Upstream commit 92d25637a3a45904292c93f1863c6bbda4e3e38f ] We have some many cases that will create child process as well, such as pidfd_wait. Previously, we will signal/kill the parent process when it is time out, but this signal will not be sent to its child process. In such case, if child process doesn't terminate itself, ksefltest framework will hang forever. Here we group all its child processes so that kill() can signal all of them in timeout.

[PATCH AUTOSEL 5.10 03/27] selftests: rtc: Increase test timeout so that all tests run

by Sasha Levin

From: Nícolas F. R. A. Prado <nfraprado(a)collabora.com> [ Upstream commit f034cc1301e7d83d4ec428dd6b8ffb57ca446efb ] The timeout setting for the rtc kselftest is currently 90 seconds. This setting is used by the kselftest runner to stop running a test if it takes longer than the assigned value. However, two of the test cases inside rtc set alarms. These alarms are set to the next beginning of the minute, so each of these test cases may take up to, in the worst case, 60 seconds. In order to allow for all test cases in rtc to run, even in the worst case, when using the kselftest runner, the timeout value should be increased to at least 120. Set it to 180, so there's some additional slack. Correct operation can be tested by running the following command right after the start of a minute (low second count), and checking that all test cases run: ./run_kselftest.sh -c rtc Signed-off-by: Nícolas F.

[PATCH AUTOSEL 5.15 21/36] kselftest: Fix vdso_test_abi return status

by Sasha Levin

From: Vincenzo Frascino <vincenzo.frascino(a)arm.com> [ Upstream commit ec049891b2dc16591813eacaddc476b3d27c8c14 ] vdso_test_abi contains a batch of tests that verify the validity of the vDSO ABI. When a vDSO symbol is not found the relevant test is skipped reporting KSFT_SKIP. All the tests return values are then added in a single variable which is checked to verify failures. This approach can have side effects which result in reporting the wrong kselftest exit status. Fix vdso_test_abi verifying the return code of each test separately.

[PATCH AUTOSEL 5.15 10/36] selftests/zram: Adapt the situation that /dev/zram0 is being used

by Sasha Levin

From: Yang Xu <xuyang2018.jy(a)fujitsu.com> [ Upstream commit 01dabed20573804750af5c7bf8d1598a6bf7bf6e ] If zram-generator package is installed and works, then we can not remove zram module because zram swap is being used. This case needs a clean zram environment, change this test by using hot_add/hot_remove interface. So even zram device is being used, we still can add zram device and remove them in cleanup. The two interface was introduced since kernel commit 6566d1a32bf7("zram: add dynamic device add/remove functionality") in v4.2-rc1. If kernel supports these two interface, we use hot_add/hot_remove to slove this problem, if not, just check whether zram is being used or built in, then skip it on old kernel.

[PATCH AUTOSEL 5.15 09/36] selftests/zram01.sh: Fix compression ratio calculation

by Sasha Levin

From: Yang Xu <xuyang2018.jy(a)fujitsu.com> [ Upstream commit d18da7ec3719559d6e74937266d0416e6c7e0b31 ] zram01 uses `free -m` to measure zram memory usage. The results are no sense because they are polluted by all running processes on the system. We Should only calculate the free memory delta for the current process. So use the third field of /sys/block/zram<id>/mm_stat to measure memory usage instead. The file is available since kernel 4.1. orig_data_size(first): uncompressed size of data stored in this disk. compr_data_size(second): compressed size of data stored in this disk mem_used_total(third): the amount of memory allocated for this disk Also remove useless zram cleanup call in zram_fill_fs and so we don't need to cleanup zram twice if fails.

[PATCH AUTOSEL 5.15 05/36] kselftest: signal all child processes

From: Li Zhijian <lizhijian(a)cn.fujitsu.com> [ Upstream commit 92d25637a3a45904292c93f1863c6bbda4e3e38f ] We have some many cases that will create child process as well, such as pidfd_wait. Previously, we will signal/kill the parent process when it is time out, but this signal will not be sent to its child process. In such case, if child process doesn't terminate itself, ksefltest framework will hang forever. Here we group all its child processes so that kill() can signal all of them in timeout.

[PATCH AUTOSEL 5.15 04/36] selftests: rtc: Increase test timeout so that all tests run

by Sasha Levin

From: Nícolas F. R. A. Prado <nfraprado(a)collabora.com> [ Upstream commit f034cc1301e7d83d4ec428dd6b8ffb57ca446efb ] The timeout setting for the rtc kselftest is currently 90 seconds. This setting is used by the kselftest runner to stop running a test if it takes longer than the assigned value. However, two of the test cases inside rtc set alarms. These alarms are set to the next beginning of the minute, so each of these test cases may take up to, in the worst case, 60 seconds. In order to allow for all test cases in rtc to run, even in the worst case, when using the kselftest runner, the timeout value should be increased to at least 120. Set it to 180, so there's some additional slack. Correct operation can be tested by running the following command right after the start of a minute (low second count), and checking that all test cases run: ./run_kselftest.sh -c rtc Signed-off-by: Nícolas F.

[PATCH AUTOSEL 5.15 03/36] kunit: tool: Import missing importlib.abc

[PATCH AUTOSEL 5.16 26/42] kselftest: Fix vdso_test_abi return status

by Sasha Levin

From: Vincenzo Frascino <vincenzo.frascino(a)arm.com> [ Upstream commit ec049891b2dc16591813eacaddc476b3d27c8c14 ] vdso_test_abi contains a batch of tests that verify the validity of the vDSO ABI. When a vDSO symbol is not found the relevant test is skipped reporting KSFT_SKIP. All the tests return values are then added in a single variable which is checked to verify failures. This approach can have side effects which result in reporting the wrong kselftest exit status. Fix vdso_test_abi verifying the return code of each test separately.

[PATCH AUTOSEL 5.16 13/42] selftests/zram: Adapt the situation that /dev/zram0 is being used

by Sasha Levin

From: Yang Xu <xuyang2018.jy(a)fujitsu.com> [ Upstream commit 01dabed20573804750af5c7bf8d1598a6bf7bf6e ] If zram-generator package is installed and works, then we can not remove zram module because zram swap is being used. This case needs a clean zram environment, change this test by using hot_add/hot_remove interface. So even zram device is being used, we still can add zram device and remove them in cleanup. The two interface was introduced since kernel commit 6566d1a32bf7("zram: add dynamic device add/remove functionality") in v4.2-rc1. If kernel supports these two interface, we use hot_add/hot_remove to slove this problem, if not, just check whether zram is being used or built in, then skip it on old kernel.

[PATCH AUTOSEL 5.16 12/42] selftests/zram01.sh: Fix compression ratio calculation

by Sasha Levin

From: Yang Xu <xuyang2018.jy(a)fujitsu.com> [ Upstream commit d18da7ec3719559d6e74937266d0416e6c7e0b31 ] zram01 uses `free -m` to measure zram memory usage. The results are no sense because they are polluted by all running processes on the system. We Should only calculate the free memory delta for the current process. So use the third field of /sys/block/zram<id>/mm_stat to measure memory usage instead. The file is available since kernel 4.1. orig_data_size(first): uncompressed size of data stored in this disk. compr_data_size(second): compressed size of data stored in this disk mem_used_total(third): the amount of memory allocated for this disk Also remove useless zram cleanup call in zram_fill_fs and so we don't need to cleanup zram twice if fails.

[PATCH AUTOSEL 5.16 11/42] selftests/zram: Skip max_comp_streams interface on newer kernel

From: Yang Xu <xuyang2018.jy(a)fujitsu.com> [ Upstream commit fc4eb486a59d70bd35cf1209f0e68c2d8b979193 ] Since commit 43209ea2d17a ("zram: remove max_comp_streams internals"), zram has switched to per-cpu streams.

[PATCH AUTOSEL 5.16 07/42] kselftest: signal all child processes

by Sasha Levin

From: Li Zhijian <lizhijian(a)cn.fujitsu.com> [ Upstream commit 92d25637a3a45904292c93f1863c6bbda4e3e38f ] We have some many cases that will create child process as well, such as pidfd_wait. Previously, we will signal/kill the parent process when it is time out, but this signal will not be sent to its child process. In such case, if child process doesn't terminate itself, ksefltest framework will hang forever. Here we group all its child processes so that kill() can signal all of them in timeout.

[PATCH AUTOSEL 5.16 06/42] selftests: rtc: Increase test timeout so that all tests run

by Sasha Levin

From: Nícolas F. R. A. Prado <nfraprado(a)collabora.com> [ Upstream commit f034cc1301e7d83d4ec428dd6b8ffb57ca446efb ] The timeout setting for the rtc kselftest is currently 90 seconds. This setting is used by the kselftest runner to stop running a test if it takes longer than the assigned value. However, two of the test cases inside rtc set alarms. These alarms are set to the next beginning of the minute, so each of these test cases may take up to, in the worst case, 60 seconds. In order to allow for all test cases in rtc to run, even in the worst case, when using the kselftest runner, the timeout value should be increased to at least 120. Set it to 180, so there's some additional slack. Correct operation can be tested by running the following command right after the start of a minute (low second count), and checking that all test cases run: ./run_kselftest.sh -c rtc Signed-off-by: Nícolas F.

[PATCH net-next 0/4] inet: Separate DSCP from ECN bits using new dscp_t type

by Guillaume Nault

The networking stack currently doesn't clearly distinguish between DSCP and ECN bits. The entire DSCP+ECN bits are stored in u8 variables (or structure fields), and each part of the stack handles them in their own way, using different macros. This has created several bugs in the past and some uncommon code paths are still unfixed. Such bugs generally manifest by selecting invalid routes because of ECN bits interfering with FIB routes and rules lookups (more details in the LPC 2021 talk[1] and in the RFC of this series[2]). This patch series aims at preventing the introduction of such bugs (and detecting existing ones), by introducing a dscp_t type, representing "sanitised" DSCP values (that is, with no ECN information), as opposed to plain u8 values that contain both DSCP and ECN information. dscp_t makes it clear for the reader what we're working on, and Sparse can flag invalid interactions between dscp_t and plain u8. This series converts only a few variables and structures: * Patch 1 converts the tclass field of struct fib6_rule. It effectively forbids the use of ECN bits in the tos/dsfield option of ip -6 rule. Rules now match packets solely based on their DSCP bits, so ECN doesn't influence the result any more. This contrasts with the previous behaviour where all 8 bits of the Traffic Class field were used. It is believed that this change is acceptable as matching ECN bits wasn't usable for IPv4, so only IPv6-only deployments could be depending on it. Also the previous behaviour made DSCP-based ip6-rules fail for packets with both a DSCP and an ECN mark, which is another reason why any such deploy is unlikely. * Patch 2 converts the tos field of struct fib4_rule. This one too effectively forbids defining ECN bits, this time in ip -4 rule. Before that, setting ECN bit 1 was accepted, while ECN bit 0 was rejected. But even when accepted, the rule would never match, as the packets would have their ECN bits cleared before doing the rule lookup. * Patch 3 converts the fc_tos field of struct fib_config. This is equivalent to patch 2, but for IPv4 routes. Routes using a tos/dsfield option with any ECN bit set is now rejected. Before this patch, they were accepted but, as with ip4 rules, these routes couldn't match any packet, since their ECN bits are cleared before the lookup. * Patch 4 converts the fa_tos field of struct fib_alias. This one is pure internal u8 to dscp_t conversion. While patches 1-3 had user facing consequences, this patch shouldn't have any side effect and is there to give an overview of what future conversion patches will look like. Conversions are quite mechanical, but imply some code churn, which is the price for the extra clarity a possibility of type checking. To summarise, all the behaviour changes required for the dscp_t type approach to work should be contained in patches 1-3. These changes are edge cases of ip-route and ip-rule that don't currently work properly. So they should be safe. Also, a kernel selftest is added for each of them. Finally, this work also paves the way for allowing the usage of the 3 high order DSCP bits in IPv4 (a few call paths already handle them, but in general the stack clears them before IPv4 rule and route lookups).

[PATCH 1/3] list: test: Add test for list_del_init_careful()

by David Gow

The list_del_init_careful() function was added[1] after the list KUnit test. Add a very basic test to cover it. Note that this test only covers the single-threaded behaviour (which matches list_del_init()), as is already the case with the test for list_empty_careful().

[PATCH 0/3] selftests: Remove duplicate CPUID wrappers

by Reinette Chatre

A few tests that require running CPUID do so with a private implementation of a wrapper for CPUID. This duplication of the CPUID wrapper should be avoided but having one is also unnecessary because of the existence of a macro that can be used instead. This series replaces private CPUID wrappers with calls to the __cpuid_count() macro from cpuid.h as made available by gcc and clang/llvm.

[PATCH v3 1/2] kselftest: alsa: Check for event generation when we write to controls

by Mark Brown

Add some coverage of event generation to mixer-test. Rather than doing a separate set of writes designed to trigger events we add a step to the existing write_and_verify() which checks to see if the value we read back from non-volatile controls matches the value before writing and that an event is or isn't generated as appropriate. The "tests" for events then simply check that no spurious or missing events were detected. This avoids needing further logic to generate appropriate values for each control type and maximises coverage. When checking for events we use a timeout of 0. This relies on the kernel generating any event prior to returning to userspace when setting a control. That is currently the case and it is difficult to see it changing, if it does the test will need to be updated. Using a delay of 0 means that we don't slow things down unduly when checking for no event or when events fail to be generated. We don't check behaviour for volatile controls since we can't tell what the behaviour is supposed to be for any given control.

[PATCH net-next] selftests: rtnetlink: Use more sensible tos values

by Guillaume Nault

Using tos 0x1 with 'ip route get <IPv4 address> ...' doesn't test much of the tos option handling: 0x1 just sets an ECN bit, which is cleared by inet_rtm_getroute() before doing the fib lookup. Let's use 0x10 instead, which is actually taken into account in the route lookup (and is less surprising for the reader). For consistency, use 0x10 for the IPv6 route lookup too (IPv6 currently doesn't clear ECN bits, but might do so in the future).

[PATCH net-next] selftests: fib offload: use sensible tos values

by Guillaume Nault

Although both iproute2 and the kernel accept 1 and 2 as tos values for new routes, those are invalid. These values only set ECN bits, which are ignored during IPv4 fib lookups. Therefore, no packet can actually match such routes. This selftest therefore only succeeds because it doesn't verify that the new routes do actually work in practice (it just checks if the routes are offloaded or not). It makes more sense to use tos values that don't conflict with ECN. This way, the selftest won't be affected if we later decide to warn or even reject invalid tos configurations for new routes.

RFC - kernel test result specification (KTAP)

by Rae Moar

We are looking to further standardise the output format used by kernel test frameworks like kselftest and KUnit. Thus far we have used the TAP (Test Anything Protocol) specification, but it has been extended in many different ways, so we would like to agree on a common "Kernel TAP" (KTAP) format to resolve these differences. Thus, below is a draft of a specification of KTAP. Note that this specification is largely based on the current format of test results for KUnit tests. Additionally, this specification was heavily inspired by the KTAP specification draft by Tim Bird (https://lore.kernel.org/linux-kselftest/CY4PR13MB1175B804E31E502221BC8163FD…). However, there are some notable differences to his specification. One such difference is the format of nested tests is more fully specified in the following specification. However, they are specified in a way which may not be compatible with many kselftest nested tests. ===================== Specification of KTAP ===================== TAP, or the Test Anything Protocol is a format for specifying test results used by a number of projects. It's website and specification are found at: https://testanything.org/. The Linux Kernel uses TAP output for test results. However, KUnit (and other Kernel testing frameworks such as kselftest) have some special needs for test results which don't gel perfectly with the original TAP specification. Thus, a "Kernel TAP" (KTAP) format is specified to extend and alter TAP to support these use-cases. KTAP Output consists of 5 major elements (all line-based): - The version line - Plan lines - Test case result lines - Diagnostic lines - A bail out line An important component in this specification of KTAP is the specification of the format of nested tests. This can be found in the section on nested tests below. The version line ---------------- The first line of KTAP output must be the version line. As this specification documents the first version of KTAP, the recommended version line is "KTAP version 1". However, since all kernel testing frameworks use TAP version lines, "TAP version 14" and "TAP version 13" are all acceptable version lines. Version lines with other versions of TAP or KTAP will not cause the parsing of the test results to fail but it will produce an error. Plan lines ---------- Plan lines must follow the format of "1..N" where N is the number of subtests. The second line of KTAP output must be a plan line, which indicates the number of tests at the highest level, such that the tests do not have a parent. Also, in the instance of a test having subtests, the second line of the test after the subtest header must be a plan line which indicates the number of subtests within that test. Test case result lines ---------------------- Test case result lines must have the format: <result> <number> [-] [<description>] [<directive>] [<diagnostic data>] The result can be either "ok", which indicates the test case passed, or "not ok", which indicates that the test case failed. The number represents the number of the test case or suite being performed. The first test case or suite must have the number 1 and the number must increase by 1 for each additional test case or result at the same level and within the same testing suite. The "-" character is optional. The description is a description of the test, generally the name of the test, and can be any string of words (can't include #). The description is optional. The directive is used to indicate if a test was skipped. The format for the directive is: "# SKIP [<skip_description>]". The skip_description is optional and can be any string of words to describe why the test was skipped. The result of the test case result line can be either "ok" or "not ok" if the skip directive is used. Finally, note that TAP 14 specification includes TODO directives but these are not supported for KTAP. Examples of test case result lines: Test passed: ok 1 - test_case_name Test was skipped: not ok 1 - test_case_name # SKIP test_case_name should be skipped Test failed: not_ok 1 - test_case_name Diagnostic lines ---------------- Diagnostic lines are used for description of testing operations. Diagnostic lines are generally formatted as "# <diagnostic_description>", where the description can be any string. However, in practice, diagnostic lines are all lines that don't follow the format of any other KTAP line format. Diagnostic lines can be anywhere in the test output after the first two lines. There are a few special diagnostic lines. Diagnostic lines of the format "# Subtest: <test_name>" indicate the start of a test with subtests. Also, diagnostic lines of the format "# <test_name>: <description>" refer to a specific test and tend to occur before the test result line of that test but are optional. Bail out line ------------- A bail out line can occur anywhere in the KTAP output and will indicate that a test has crashed. The format of a bail out line is "Bail out! [<description>]", where the description can give information on why the bail out occurred and can be any string. Nested tests ------------ The new specification for KTAP will support an arbitrary number of nested subtests. Thus, tests can now have subtests and those subtests can have subtests. This can be useful to further categorize tests and organize test results. The new required format for a test with subtests consists of: a subtest header line, a plan line, all subtests, and a final test result line. The first line of the test must be the subtest header line with the format: "# Subtest: <test_name>". The second line of the test must be the plan line, which is formatted as "1..N", where N is the number of subtests. Following the plan line, all lines pertaining to the subtests will follow. Finally, the last line of the test is a final test result line with the format: "(ok|not ok) <number> [-] [<description>] [<directive>] [<diagnostic data>]", which follows the same format as the general test result lines described in this section. The result line should indicate the result of the subtests. Thus, if one of the subtests fail, the test should fail. The description in the final test result line should match the name of the test in the subtest header. An example format: KTAP version 1 1..1 # Subtest: test_suite 1..2 ok 1 - test_1 ok 2 - test_2 ok 1 - test_suite An example format with multiple levels of nested testing: KTAP version 1 1..1 # Subtest: test_suite 1..2 # Subtest: sub_test_suite 1..2 ok 1 - test_1 ok 2 test_2 ok 1 - sub_test_suite ok 2 - test ok 1 - test_suite In the instance that the plan line is missing, the end of the test will be denoted by the final result line containing a description that matches the name of the test given in the subtest header. Note that thus, if the plan line is missing and one of the subtests have a matching name to the test suite this will cause errors. Lastly, indentation is also recommended for improved readability. Major differences between TAP 14 and KTAP specification ------------------------------------------------------- Note that the major differences between TAP 14 and KTAP specification: - yaml and json are not allowed in diagnostic messages - TODO directive not allowed - KTAP allows for an arbitrary number of tests to be nested with specified nested test format Example of KTAP --------------- KTAP version 1 1..1 # Subtest: test_suite 1..1 # Subtest: sub_test_suite 1..2 ok 1 - test_1 ok 2 test_2 ok 1 - sub_test_suite ok 1 - test_suite ========================================= Note on incompatibilities with kselftests ========================================= To my knowledge, the above specification seems to generally accept the TAP format of many non-nested test results of kselftests. An example of a common kselftests TAP format for non-nested test results that are accepted by the above specification: TAP version 13 1..2 # selftests: vDSO: vdso_test_gettimeofday # The time is 1628024856.096879 ok 1 selftests: vDSO: vdso_test_gettimeofday # selftests: vDSO: vdso_test_getcpu # Could not find __vdso_getcpu ok 2 selftests: vDSO: vdso_test_getcpu # SKIP However, one major difference noted with kselftests is the use of more directives than the "# SKIP" directive. kselftest also supports XPASS and XFAIL directives. Some additional examples found in kselftests: not ok 5 selftests: netfilter: nft_concat_range.sh # TIMEOUT 45 seconds not ok 45 selftests: kvm: kvm_binary_stats_test # exit=127 Should the specification be expanded to include these directives? However, the general format for kselftests with nested test results seems to differ from the above specification. It seems that a general format for nested tests is as follows: TAP version 13 1..2 # selftests: membarrier: membarrier_test_single_thread # TAP version 13 # 1..2 # ok 1 sys_membarrier available # ok 2 sys membarrier invalid command test: command = -1, flags = 0, errno = 22. Failed as expected ok 1 selftests: membarrier: membarrier_test_single_thread # selftests: membarrier: membarrier_test_multi_thread # TAP version 13 # 1..2 # ok 1 sys_membarrier available # ok 2 sys membarrier invalid command test: command = -1, flags = 0, errno = 22. Failed as expected ok 2 selftests: membarrier: membarrier_test_multi_thread The major differences here, that do not match the above specification, are use of "# " as an indentation and using a TAP version line to denote a new test with subtests rather than the subtest header line described above. If these are widely utilized formats in kselftests, should we include both versions in the specification or should we attempt to agree on a single format for nested tests? I personally believe we should try to agree on a single format for nested tests. This would allow for a cleaner specification of KTAP and would reduce possible confusion. ==== So what do people think about the above specification? How should we handle the differences with kselftests? If this specification is accepted, where should the specification be documented?

kselftest tree on kernelci.org

by Guillaume Tucker

Hi Shuah, I've made this PR to start monitoring the "fixes" branch from the kselftest tree on kernelci.org: https://github.com/kernelci/kernelci-core/pull/998 While kselftest changes eventually land in linux-next, monitoring your tree directly means we can test it earlier and potentially enable more build variants or experimental tests. Since kernelci.org also builds and runs some kselftests we're regularly finding issues and people are sending fixes for them. See this recent story for example: https://twitter.com/kernelci/status/1488831497259921409 Keeping an eye on kselftest patches with kernelci.org means we can verify that fixes do what they're supposed to do with a much larger test coverage than what individual developers can do. We've been applying kselftest fixes on a branch managed by kernelci.org to verify them in the past, but having the actual kselftest tree part of the workflow would seem much better. There are several branches in your tree, while "fixes" seemed like the most useful one to pick I see there is also a "kernelci" branch too but it hasn't been updated for a while, reviving it could give you the possibility to test patches through kernelci.org before applying them on other branches that get pulled into linux-next and mainline. Many things could potentially be done with arbitrary builds and tests etc. These are some initial suggestions. How does this sound? Best wishes, Guillaume

[PATCH v2 net-next 5/5] selftests: net: bridge: Parameterize ageing timeout

[PATCH 0/2] KVM: selftests: Add powerpc support

by Fabiano Rosas

This series adds the initial support for ppc64le Book3s with Radix MMU. At this time I'm including only the kvm_page_table test and a dummy test to serve as a sample of what can be done with these tests. I intend to make a pass over the remaining common tests and add the ones which could be built for powerpc as well. patch 1: a prerequisite small fix for the powerpc vcpu_ioctl. It is the same I already sent to the ppc mailing list but I'll include it here to make this a complete series. patch 2: the actual infrastructure support.

[PATCH] selftests: fixup build warnings in pidfd / clone3 tests

by Axel Rasmussen

These are some trivial fixups, which were needed to build the tests with clang and -Werror. The following issues are fixed: - Remove various unused variables. - In child_poll_leader_exit_test, clang isn't smart enough to realize syscall(SYS_exit, 0) won't return, so it complains we never return from a non-void function. Add an extra exit(0) to appease it. - In test_pidfd_poll_leader_exit, ret may be branched on despite being uninitialized, if we have !use_waitpid. Initialize it to zero to get the right behavior in that case.

[PATCH] pidfd: fix test failure due to stack overflow on some arches

by Axel Rasmussen

When running the pidfd_fdinfo_test on arm64, it fails for me. After some digging, the reason is that the child exits due to SIGBUS, because it overflows the 1024 byte stack we've reserved for it. To fix the issue, increase the stack size to 8192 bytes (this number is somewhat arbitrary, and was arrived at through experimentation -- I kept doubling until the failure no longer occurred). Also, let's make the issue easier to debug. wait_for_pid() returns an ambiguous value: it may return -1 in all of these cases: 1. waitpid() itself returned -1 2. waitpid() returned success, but we found !WIFEXITED(status). 3. The child process exited, but it did so with a -1 exit code. There's no way for the caller to tell the difference. So, at least log which occurred, so the test runner can debug things. While debugging this, I found that we had !WIFEXITED(), because the child exited due to a signal. This seems like a reasonably common case, so also print out whether or not we have WIFSIGNALED(), and the associated WTERMSIG() (if any). This lets us see the SIGBUS I'm fixing clearly when it occurs. Finally, I'm suspicious of allocating the child's stack on our stack. man clone(2) suggests that the correct way to do this is with mmap(), and in particular by setting MAP_STACK. So, switch to doing it that way instead.

[PATCH v2 1/2] kselftest: alsa: Check for event generation when we write to controls

by Mark Brown

Add some coverage of event generation to mixer-test. Rather than doing a separate set of writes designed to trigger events we add a step to the existing write_and_verify() which checks to see if the value we read back from non-volatile controls matches the value before writing and that an event is or isn't generated as appropriate. The "tests" for events then simply check that no spurious or missing events were detected. This avoids needing further logic to generate appropriate values for each control type and maximises coverage. When checking for events we use a timeout of 0. This relies on the kernel generating any event prior to returning to userspace when setting a control. That is currently the case and it is difficult to see it changing, if it does the test will need to be updated. Using a delay of 0 means that we don't slow things down unduly when checking for no event or when events fail to be generated.

[PATCH] kselftest: alsa: Check for event generation when we write to controls

by Mark Brown

Add some coverage of event generation to mixer-test. Rather than doing a separate set of writes designed to trigger events we add a step to the existing write_and_verify() which checks to see if the value we read back from non-volatile controls matches the value before writing and that an event is or isn't generated as appropriate. The "tests" for events then simply check that no spurious or missing events were detected. This avoids needing further logic to generate appropriate values for each control type and maximises coverage. When checking for events we use a timeout of 0. This relies on the kernel generating any event prior to returning to userspace when setting a control. That is currently the case and it is difficult to see it changing, if it does the test will need to be updated. Using a delay of 0 means that we don't slow things down unduly when checking for no event or when events fail to be generated. We don't check behaviour for volatile controls since we can't tell what the behaviour is supposed to be for any given control.

[PATCH v4] kselftest: Fix vdso_test_abi return status

by Vincenzo Frascino

vdso_test_abi contains a batch of tests that verify the validity of the vDSO ABI. When a vDSO symbol is not found the relevant test is skipped reporting KSFT_SKIP. All the tests return values are then added in a single variable which is checked to verify failures. This approach can have side effects which result in reporting the wrong kselftest exit status. Fix vdso_test_abi verifying the return code of each test separately.

[PATCH bpf-next v2 0/6] tools/bpf: Enable cross-building with clang

by Jean-Philippe Brucker

Since v1 [1], I added Quentin's acks and applied Andrii's suggestions: * Pass CFLAGS to libbpf link in patch 3 * Substitute CLANG_CROSS_FLAGS whole in HOST_CFLAGS to avoid accidents, patch 4 Add support for cross-building BPF tools and selftests with clang, by passing LLVM=1 or CC=clang to make, as well as CROSS_COMPILE. A single clang toolchain can generate binaries for multiple architectures, so instead of having prefixes such as aarch64-linux-gnu-gcc, clang uses the -target parameter: `clang -target aarch64-linux-gnu'. Patch 1 adds the parameter in Makefile.include so tools can easily support this. Patch 2 prepares for the libbpf change from patch 3 (keep building resolve_btfids's libbpf in the host arch, when cross-building the kernel with clang). Patches 3-6 enable cross-building BPF tools with clang.

[PATCH net-next 5/5] selftests: net: bridge: Parameterize ageing timeout

Allow the ageing timeout that is set on bridges to be customized from forwarding.config. This allows the tests to be run on hardware which does not support a 10s timeout (e.g. mv88e6xxx).

[PATCH v3] kselftest: Fix vdso_test_abi return status

by Vincenzo Frascino

vdso_test_abi contains a batch of tests that verify the validity of the vDSO ABI. When a vDSO symbol is not found the relevant test is skipped reporting KSFT_SKIP. All the tests return values are then added in a single variable which is checked to verify failures. This approach can have side effects which result in reporting the wrong kselftest exit status. Fix vdso_test_abi verifying the return code of each test separately.

[PATCH] kunit: cleanup assertion macro internal variables

by Daniel Latypov

All the operands should be tagged `const`. We're only assigning them to variables so that we can compare them (e.g. check if left == right, etc.) and avoid evaluating expressions multiple times. There's no need for them to be mutable. Also rename the helper variable `loc` to `__loc` like we do with `__assertion` and `__strs` to avoid potential name collisions with user code.

[RFC PATCH] kunit: flatten kunit_suite*** to kunit_suite** in executor

by Daniel Latypov

Per [1], we might not need the array-of-array of kunit_suite's. This RFC patch previews the changes we'd make to the executor to accommodate that by making the executor automatically flatten the kunit_suite*** into a kunit_suite**. The test filtering support [2] added the largest dependency on the current kunit_suite*** layout, so this patch is based on that. It actually drastically simplifies the code, so it might be useful to keep the auto-flattening step until we actually make the change.

[PATCH v2] kselftest: Fix vdso_test_abi return status

by Vincenzo Frascino

vdso_test_abi contains a batch of tests that verify the validity of the vDSO ABI. When a vDSO symbol is not found the relevant test is skipped reporting KSFT_SKIP. All the tests return values are then added in a single variable which is checked to verify failures. This approach can have side effects which result in reporting the wrong kselftest exit status. Fix vdso_test_abi verifying the return code of each test separately.

Hi Shuah, a small series collecting a few trivial fixes that I have already sent previously (~Dec2021) as distinct patches. They are mostly trivial patches addressing failures that seemed more sensible to be marked as skips instead. (at least to me ...). Original developers are in Cc. (but not heard back from anyone :D) Thanks, Cristian Cristian Marussi (5): selftests: skip mincore.check_file_mmap when fs lacks needed support kselftest: Fix vdso_test_time to pass on skips selftests: openat2: Print also errno in failure messages selftests: openat2: Add missing dependency in Makefile selftests: openat2: Skip testcases that fail with EOPNOTSUPP .../selftests/mincore/mincore_selftest.c | 20 +++++++++++++------ tools/testing/selftests/openat2/Makefile | 2 +- tools/testing/selftests/openat2/helpers.h | 12 ++++++----- .../testing/selftests/openat2/openat2_test.c | 12 ++++++++++- tools/testing/selftests/vDSO/vdso_test_abi.c | 3 ++- 5 files changed, 35 insertions(+), 14 deletions(-) -- 2.17.1

[RFC PATCH 00/15] rseq uapi and selftest updates

by Mathieu Desnoyers

Update the rseq selftests to adapt to the userspace ABI chosen by glibc (will be released in February 2022). Provide a fallback implementation to work with older glibc as well. Remove broken 32-bit little/big endian accessor fields in rseq uapi. Integrate various fixes gathered from librseq, including work-around for known gcc and clang compiler bugs with asm goto.

[PATCH v4] selftests/kselftest/runner.sh: Pass optional command parameters in environment

[PATCH 0/3] kunit: further reduce stack usage of asserts

by Daniel Latypov

If the compiler doesn't optimize them away, each kunit assertion (use of KUNIT_EXPECT_EQ, etc.) can use 88 bytes of stack space in the worst and most common case. This has led to compiler warnings for certain configs + arches [1]. This series builds upon [2] which cut down kunit_assert from 48 => 24 bytes, but only reduced kunit_binary_assert (the most common one) from 88 => 48. Now we have kunit_assert = 8 and kunit_binary_assert = 32. The cost is we need to pass around another parameter to some functions (struct va_format *), and we introduce a new type (sturct kunit_binary_assert_text) for holding the textual representation of the KUNIT_EXPECT_EQ arguments. Note: it's possible to get kunit_assert = 0 and kunit_binary_assert = 24 by removing the `format` function pointer field from kunit_assert. I think it's an improvement, but others might think that readability suffers from doing so, so I'm leaving that off from this series. Meta: this series applies on top of 5.17-rc1 + [2] and [3]. That should be available at in Shuah's kunit branch [4], but my version of git is constantly segfaulting, so I can't try and rebase to verify.

[PATCH v3] kselftest: kvm/arm64: Skip tests if we can't create a vgic-v3

by Mark Brown

The arch_timer and vgic_irq kselftests assume that they can create a vgic-v3, using the library function vgic_v3_setup() which aborts with a test failure if it is not possible to do so. Since vgic-v3 can only be instantiated on systems where the host has GICv3 this leads to false positives on older systems where that is not the case. Fix this by changing vgic_v3_setup() to return an error if the vgic can't be instantiated and have the callers skip if this happens. We could also exit flagging a skip in vgic_v3_setup() but this would prevent future test cases conditionally deciding which GIC to use or generally doing more complex output. Signed-off-by: Mark Brown <broonie(a)kernel.org> --- v3: - Use custom print_skip() helper. - Use internal version of _kvm_create_device. v2: - The test for being able to create the GIC doesn't actually instantiate it, add a call doing so in that case. tools/testing/selftests/kvm/aarch64/arch_timer.c | 7 ++++++- tools/testing/selftests/kvm/aarch64/vgic_irq.c | 4 ++++ tools/testing/selftests/kvm/lib/aarch64/vgic.c | 4 +++- 3 files changed, 13 insertions(+), 2 deletions(-) diff --git a/tools/testing/selftests/kvm/aarch64/arch_timer.c b/tools/testing/selftests/kvm/aarch64/arch_timer.c index 9ad38bd360a4..b08d30bf71c5 100644 --- a/tools/testing/selftests/kvm/aarch64/arch_timer.c +++ b/tools/testing/selftests/kvm/aarch64/arch_timer.c @@ -366,6 +366,7 @@ static struct kvm_vm *test_vm_create(void) { struct kvm_vm *vm; unsigned int i; + int ret; int nr_vcpus = test_args.nr_vcpus; vm = vm_create_default_with_vcpus(nr_vcpus, 0, 0, guest_code, NULL); @@ -382,7 +383,11 @@ static struct kvm_vm *test_vm_create(void) ucall_init(vm, NULL); test_init_timer_irq(vm); - vgic_v3_setup(vm, nr_vcpus, 64, GICD_BASE_GPA, GICR_BASE_GPA); + ret = vgic_v3_setup(vm, nr_vcpus, 64, GICD_BASE_GPA, GICR_BASE_GPA); + if (ret < 0) { + print_skip("Failed to create vgic-v3"); + exit(KSFT_SKIP); + } /* Make all the test's cmdline args visible to the guest */ sync_global_to_guest(vm, test_args); diff --git a/tools/testing/selftests/kvm/aarch64/vgic_irq.c b/tools/testing/selftests/kvm/aarch64/vgic_irq.c index e6c7d7f8fbd1..7eca97799917 100644 --- a/tools/testing/selftests/kvm/aarch64/vgic_irq.c +++ b/tools/testing/selftests/kvm/aarch64/vgic_irq.c @@ -761,6 +761,10 @@ static void test_vgic(uint32_t nr_irqs, bool level_sensitive, bool eoi_split) gic_fd = vgic_v3_setup(vm, 1, nr_irqs, GICD_BASE_GPA, GICR_BASE_GPA); + if (gic_fd < 0) { + print_skip("Failed to create vgic-v3, skipping"); + exit(KSFT_SKIP); + } vm_install_exception_handler(vm, VECTOR_IRQ_CURRENT, guest_irq_handlers[args.eoi_split][args.level_sensitive]); diff --git a/tools/testing/selftests/kvm/lib/aarch64/vgic.c b/tools/testing/selftests/kvm/lib/aarch64/vgic.c index b3a0fca0d780..f5cd0c536d85 100644 --- a/tools/testing/selftests/kvm/lib/aarch64/vgic.c +++ b/tools/testing/selftests/kvm/lib/aarch64/vgic.c @@ -52,7 +52,9 @@ int vgic_v3_setup(struct kvm_vm *vm, unsigned int nr_vcpus, uint32_t nr_irqs, nr_vcpus, nr_vcpus_created); /* Distributor setup */ - gic_fd = kvm_create_device(vm, KVM_DEV_TYPE_ARM_VGIC_V3, false); + if (_kvm_create_device(vm, KVM_DEV_TYPE_ARM_VGIC_V3, + false, &gic_fd) != 0) + return -1; kvm_device_access(gic_fd, KVM_DEV_ARM_VGIC_GRP_NR_IRQS, 0, &nr_irqs, true); -- 2.30.2

[PATCH 0/2] sigaltstack: return only one flag

by Stas Sergeev

Currently sigaltstack() can return multiple flags, for example SS_DISABLE|SS_AUTODISARM. This confuses libraries (including asan runtime) and contradicts the man page. Patch 1 fixes this problem by ignoring any flag passed with SS_DISABLE. Patch 2 adds a test-case for that scenario. Signed-off-by: Stas Sergeev <stsp2(a)yandex.ru> CC: "Eric W.

[PATCH v10 00/39] arm64/sme: Initial support for the Scalable Matrix Extension

by Mark Brown

This series provides initial support for the ARMv9 Scalable Matrix Extension (SME). SME takes the approach used for vectors in SVE and extends this to provide architectural support for matrix operations. A more detailed overview can be found in [1]. For the kernel SME can be thought of as a series of features which are intended to be used together by applications but operate mostly orthogonally: - The ZA matrix register. - Streaming mode, in which ZA can be accessed and a subset of SVE features are available. - A second vector length, used for streaming mode SVE and ZA and controlled using a similar interface to that for SVE. - TPIDR2, a new userspace controllable system register intended for use by the C library for storing context related to the ZA ABI. A substantial part of the series is dedicated to refactoring the existing SVE support so that we don't need to duplicate code for handling vector lengths and the SVE registers, this involves creating an array of vector types and making the users take the vector type as a parameter. I'm not 100% happy with this but wasn't able to come up with anything better, duplicating code definitely felt like a bad idea so this felt like the least bad thing. If this approach makes sense to people it might make sense to split this off into a separate series and/or merge it while the rest is pending review to try to make things a little more digestable, the series is very large so it'd probably make things easier to digest if some of the preparatory refactoring could be merged before the rest is ready. One feature of the architecture of particular note is that switching to and from streaming mode may change the size of and invalidate the contents of the SVE registers, and when in streaming mode the FFR is not accessible. This complicates aspects of the ABI like signal handling and ptrace. This initial implementation is mainly intended to get the ABI in place, there are several areas which will be worked on going forwards - some of these will be blockers, others could be handled in followup serieses: - SME is currently not supported for KVM guests, this will be done as a followup series. A host system can use SME and run KVM guests but SME is not available in the guests. - The KVM host support is done in a very simplistic way, were anyone to attempt to use it in production there would be performance impacts on hosts with SME support. As part of this we also add enumeration of fine grained traps. - There is not currently ptrace or signal support TPIDR2, this will be done as a followup series. - No support is currently provided for scheduler control of SME or SME applications, given the size of the SME register state the context switch overhead may be noticable so this may be needed especially for real time applications. Similar concerns already exist for larger SVE vector lengths but are amplified for SME, particularly as the vector length increases. - There has been no work on optimising the performance of anything the kernel does. It is not expected that any systems will be encountered that support SME but not SVE, SME is an ARMv9 feature and SVE is mandatory for ARMv9. The code attempts to handle any such systems that are encountered but this hasn't been tested extensively. v10: - Actually do the rebase of fixups from the previous version into relevant patches. v9: - Remove defensive programming around IS_ENABLED() and FGT in KVM code. - Fix naming of TPIDR2 FGT register bit. - Add patches making handling of floating point register bits more consistent (also sent as separate series). - Drop now unused enumeration of fine grained traps. v8: - Rebase onto v5.17-rc1. - Support interoperation with KVM, SME is disabled for KVM guests with minimal handling for cleaning up SME state when entering and leaving the guest. - Document and implement that signal handlers are invoked with ZA and streaming mode disabled. - Use the RDSVL instruction introduced in EAC2 of the architecture to obtain the streaming mode vector length during enumeration, ZA state loading/saving and in test programs. - Store a pointer to SVCR in fpsimd_last_state and use it in fpsimd_save() for interoperation with KVM. - Add a test case sme_trap_no_sm checking that we generate a SIGILL when using an instruction that requires streaming mode without enabling it. - Add basic ZA context form validation to testcases helper library. - Move signal tests over to validating streaming VL from ZA information. - Pulled in patch removing ARRAY_SIZE() so that kselftest builds cleanly and to avoid trivial conflicts. v7: - Rebase onto v5.16-rc3. - Reduce indentation when supporting custom triggers for signal tests as suggested by Catalin. - Change to specifying a width for all CPU features rather than adding single bit specific infrastructure. - Don't require zeroing of non-shared SVE state during syscalls. v6: - Rebase onto v5.16-rc1. - Return to disabling TIF_SVE on kernel entry even if we have SME state, this avoids the need for KVM to handle the case where TIF_SVE is set on guest entry. - Add syscall-abi.h to SME updates to syscall-abi, mistakenly omitted from commit. v5: - Rebase onto currently merged SVE and kselftest patches. - Add support for the FA64 option, introduced in the recently published EAC1 update to the specification. - Pull in test program for the syscall ABI previously sent separately with some revisions and add coverage for the SME ABI. - Fix checking for options with 1 bit fields in ID_AA64SMFR0_EL1. - Minor fixes and clarifications to the ABI documentation. v4: - Rebase onto merged patches. - Remove an uneeded NULL check in vec_proc_do_default_vl(). - Include patch to factor out utility routines in kselftests written in assembler. - Specify -ffreestanding when building TPIDR2 test. v3: - Skip FFR rather than predicate registers in sve_flush_live(). - Don't assume a bool is all zeros in sve_flush_live() as per AAPCS. - Don't redundantly specify a zero index when clearing FFR. v2: - Fix several issues with !SME and !SVE configurations. - Preserve TPIDR2 when creating a new thread/process unless CLONE_SETTLS is set. - Report traps due to using features in an invalid mode as SIGILL. - Spell out streaming mode behaviour in SVE ABI documentation more directly. - Document TPIDR2 in the ABI document. - Use SMSTART and SMSTOP rather than read/modify/write sequences. - Rework logic for exiting streaming mode on syscall. - Don't needlessly initialise SVCR on access trap. - Always restore SME VL for userspace if SME traps are disabled. - Only yield to encourage preemption every 128 iterations in za-test, otherwise do a getpid(), and validate SVCR after syscall. - Leave streaming mode disabled except when reading the vector length in za-test, and disable ZA after detecting a mismatch. - Add SME support to vlset. - Clarifications and typo fixes in comments. - Move sme_alloc() forward declaration back a patch.

[PATCH v9 00/40] arm64/sme: Initial support for the Scalable Matrix Extension

by Mark Brown

This series provides initial support for the ARMv9 Scalable Matrix Extension (SME). SME takes the approach used for vectors in SVE and extends this to provide architectural support for matrix operations. A more detailed overview can be found in [1]. For the kernel SME can be thought of as a series of features which are intended to be used together by applications but operate mostly orthogonally: - The ZA matrix register. - Streaming mode, in which ZA can be accessed and a subset of SVE features are available. - A second vector length, used for streaming mode SVE and ZA and controlled using a similar interface to that for SVE. - TPIDR2, a new userspace controllable system register intended for use by the C library for storing context related to the ZA ABI. A substantial part of the series is dedicated to refactoring the existing SVE support so that we don't need to duplicate code for handling vector lengths and the SVE registers, this involves creating an array of vector types and making the users take the vector type as a parameter. I'm not 100% happy with this but wasn't able to come up with anything better, duplicating code definitely felt like a bad idea so this felt like the least bad thing. If this approach makes sense to people it might make sense to split this off into a separate series and/or merge it while the rest is pending review to try to make things a little more digestable, the series is very large so it'd probably make things easier to digest if some of the preparatory refactoring could be merged before the rest is ready. One feature of the architecture of particular note is that switching to and from streaming mode may change the size of and invalidate the contents of the SVE registers, and when in streaming mode the FFR is not accessible. This complicates aspects of the ABI like signal handling and ptrace. This initial implementation is mainly intended to get the ABI in place, there are several areas which will be worked on going forwards - some of these will be blockers, others could be handled in followup serieses: - SME is currently not supported for KVM guests, this will be done as a followup series. A host system can use SME and run KVM guests but SME is not available in the guests. - The KVM host support is done in a very simplistic way, were anyone to attempt to use it in production there would be performance impacts on hosts with SME support. As part of this we also add enumeration of fine grained traps. - There is not currently ptrace or signal support TPIDR2, this will be done as a followup series. - No support is currently provided for scheduler control of SME or SME applications, given the size of the SME register state the context switch overhead may be noticable so this may be needed especially for real time applications. Similar concerns already exist for larger SVE vector lengths but are amplified for SME, particularly as the vector length increases. - There has been no work on optimising the performance of anything the kernel does. It is not expected that any systems will be encountered that support SME but not SVE, SME is an ARMv9 feature and SVE is mandatory for ARMv9. The code attempts to handle any such systems that are encountered but this hasn't been tested extensively. v9: - Remove defensive programming around IS_ENABLED() and FGT in KVM code. - Fix naming of TPIDR2 FGT register bit. - Add patches making handling of floating point register bits more consistent (also sent as separate series). - Drop now unused enumeration of fine grained traps. v8: - Rebase onto v5.17-rc1. - Support interoperation with KVM, SME is disabled for KVM guests with minimal handling for cleaning up SME state when entering and leaving the guest. - Document and implement that signal handlers are invoked with ZA and streaming mode disabled. - Use the RDSVL instruction introduced in EAC2 of the architecture to obtain the streaming mode vector length during enumeration, ZA state loading/saving and in test programs. - Store a pointer to SVCR in fpsimd_last_state and use it in fpsimd_save() for interoperation with KVM. - Add a test case sme_trap_no_sm checking that we generate a SIGILL when using an instruction that requires streaming mode without enabling it. - Add basic ZA context form validation to testcases helper library. - Move signal tests over to validating streaming VL from ZA information. - Pulled in patch removing ARRAY_SIZE() so that kselftest builds cleanly and to avoid trivial conflicts. v7: - Rebase onto v5.16-rc3. - Reduce indentation when supporting custom triggers for signal tests as suggested by Catalin. - Change to specifying a width for all CPU features rather than adding single bit specific infrastructure. - Don't require zeroing of non-shared SVE state during syscalls. v6: - Rebase onto v5.16-rc1. - Return to disabling TIF_SVE on kernel entry even if we have SME state, this avoids the need for KVM to handle the case where TIF_SVE is set on guest entry. - Add syscall-abi.h to SME updates to syscall-abi, mistakenly omitted from commit. v5: - Rebase onto currently merged SVE and kselftest patches. - Add support for the FA64 option, introduced in the recently published EAC1 update to the specification. - Pull in test program for the syscall ABI previously sent separately with some revisions and add coverage for the SME ABI. - Fix checking for options with 1 bit fields in ID_AA64SMFR0_EL1. - Minor fixes and clarifications to the ABI documentation. v4: - Rebase onto merged patches. - Remove an uneeded NULL check in vec_proc_do_default_vl(). - Include patch to factor out utility routines in kselftests written in assembler. - Specify -ffreestanding when building TPIDR2 test. v3: - Skip FFR rather than predicate registers in sve_flush_live(). - Don't assume a bool is all zeros in sve_flush_live() as per AAPCS. - Don't redundantly specify a zero index when clearing FFR. v2: - Fix several issues with !SME and !SVE configurations. - Preserve TPIDR2 when creating a new thread/process unless CLONE_SETTLS is set. - Report traps due to using features in an invalid mode as SIGILL. - Spell out streaming mode behaviour in SVE ABI documentation more directly. - Document TPIDR2 in the ABI document. - Use SMSTART and SMSTOP rather than read/modify/write sequences. - Rework logic for exiting streaming mode on syscall. - Don't needlessly initialise SVCR on access trap. - Always restore SME VL for userspace if SME traps are disabled. - Only yield to encourage preemption every 128 iterations in za-test, otherwise do a getpid(), and validate SVCR after syscall. - Leave streaming mode disabled except when reading the vector length in za-test, and disable ZA after detecting a mismatch. - Add SME support to vlset. - Clarifications and typo fixes in comments. - Move sme_alloc() forward declaration back a patch.

[PATCH v2] kselftest: alsa: Add test case for writing invalid values

by Mark Brown

Attempt to write various invalid values for control types we know about and check that something sensible happens. The ABI isn't quite as clearly defined as one might like, rather than generating an error when an invalid value is written many devices will silently rewrite the value into one that is valid for the control. The exact value chosen is not predictable so in the case the write succeeds we just check that the value we read back is one that is valid for the control.

[PATCH v2] kselftest: kvm/arm64: Skip tests if we can't create a vgic-v3

by Mark Brown

The arch_timer and vgic_irq kselftests assume that they can create a vgic-v3, using the library function vgic_v3_setup() which aborts with a test failure if it is not possible to do so. Since vgic-v3 can only be instantiated on systems where the host has GICv3 this leads to false positives on older systems where that is not the case. Fix this by changing vgic_v3_setup() to return an error if the vgic can't be instantiated and have the callers skip if this happens. We could also exit flagging a skip in vgic_v3_setup() but this would prevent future test cases conditionally deciding which GIC to use or generally doing more complex output.

[PATCH] tools headers UAPI: remove stale lirc.h

by Sean Young

The lirc.h file is an old copy of lirc.h from the kernel sources. It is out of date, and the bpf lirc tests don't need a new copy anyway. As long as /usr/include/linux/lirc.h is from kernel v5.2 or newer, the tests will compile fine.

[PATCH v2] selftests: rtc: Increase test timeout so that all tests run

by Nícolas F. R. A. Prado

The timeout setting for the rtc kselftest is currently 90 seconds. This setting is used by the kselftest runner to stop running a test if it takes longer than the assigned value. However, two of the test cases inside rtc set alarms. These alarms are set to the next beginning of the minute, so each of these test cases may take up to, in the worst case, 60 seconds. In order to allow for all test cases in rtc to run, even in the worst case, when using the kselftest runner, the timeout value should be increased to at least 120. Set it to 180, so there's some additional slack. Correct operation can be tested by running the following command right after the start of a minute (low second count), and checking that all test cases run: ./run_kselftest.sh -c rtc Signed-off-by: Nícolas F.

[PATCH] selftests: cpufreq: Write test output to stdout as well

by Nícolas F. R. A. Prado

Use 'tee' to send the test output to stdout in addition to the current output file. This makes the output easier to handle in automated test systems and is superior to only later dumping the output file contents to stdout, since this way the test output can be interleaved with other log messages, like from the kernel, so that chronology is preserved, making it easier to detect issues.

[PATCH v2] kselftest: signal all child processes

by Li Zhijian

We have some many cases that will create child process as well, such as pidfd_wait. Previously, we will signal/kill the parent process when it is time out, but this signal will not be sent to its child process.

[PATCH v8 00/38] arm64/sme: Initial support for the Scalable Matrix Extension

by Mark Brown

This series provides initial support for the ARMv9 Scalable Matrix Extension (SME). SME takes the approach used for vectors in SVE and extends this to provide architectural support for matrix operations. A more detailed overview can be found in [1]. For the kernel SME can be thought of as a series of features which are intended to be used together by applications but operate mostly orthogonally: - The ZA matrix register. - Streaming mode, in which ZA can be accessed and a subset of SVE features are available. - A second vector length, used for streaming mode SVE and ZA and controlled using a similar interface to that for SVE. - TPIDR2, a new userspace controllable system register intended for use by the C library for storing context related to the ZA ABI. A substantial part of the series is dedicated to refactoring the existing SVE support so that we don't need to duplicate code for handling vector lengths and the SVE registers, this involves creating an array of vector types and making the users take the vector type as a parameter. I'm not 100% happy with this but wasn't able to come up with anything better, duplicating code definitely felt like a bad idea so this felt like the least bad thing. If this approach makes sense to people it might make sense to split this off into a separate series and/or merge it while the rest is pending review to try to make things a little more digestable, the series is very large so it'd probably make things easier to digest if some of the preparatory refactoring could be merged before the rest is ready. One feature of the architecture of particular note is that switching to and from streaming mode may change the size of and invalidate the contents of the SVE registers, and when in streaming mode the FFR is not accessible. This complicates aspects of the ABI like signal handling and ptrace. This initial implementation is mainly intended to get the ABI in place, there are several areas which will be worked on going forwards - some of these will be blockers, others could be handled in followup serieses: - SME is currently not supported for KVM guests, this will be done as a followup series. A host system can use SME and run KVM guests but SME is not available in the guests. - The KVM host support is done in a very simplistic way, were anyone to attempt to use it in production there would be performance impacts on hosts with SME support. As part of this we also add enumeration of fine grained traps. - There is not currently ptrace or signal support TPIDR2, this will be done as a followup series. - No support is currently provided for scheduler control of SME or SME applications, given the size of the SME register state the context switch overhead may be noticable so this may be needed especially for real time applications. Similar concerns already exist for larger SVE vector lengths but are amplified for SME, particularly as the vector length increases. - There has been no work on optimising the performance of anything the kernel does. It is not expected that any systems will be encountered that support SME but not SVE, SME is an ARMv9 feature and SVE is mandatory for ARMv9. The code attempts to handle any such systems that are encountered but this hasn't been tested extensively. v8: - Rebase onto v5.17-rc1. - Support interoperation with KVM, SME is disabled for KVM guests with minimal handling for cleaning up SME state when entering and leaving the guest. - Document and implement that signal handlers are invoked with ZA and streaming mode disabled. - Use the RDSVL instruction introduced in EAC2 of the architecture to obtain the streaming mode vector length during enumeration, ZA state loading/saving and in test programs. - Store a pointer to SVCR in fpsimd_last_state and use it in fpsimd_save() for interoperation with KVM. - Add a test case sme_trap_no_sm checking that we generate a SIGILL when using an instruction that requires streaming mode without enabling it. - Add basic ZA context form validation to testcases helper library. - Move signal tests over to validating streaming VL from ZA information. - Pulled in patch removing ARRAY_SIZE() so that kselftest builds cleanly and to avoid trivial conflicts. v7: - Rebase onto v5.16-rc3. - Reduce indentation when supporting custom triggers for signal tests as suggested by Catalin. - Change to specifying a width for all CPU features rather than adding single bit specific infrastructure. - Don't require zeroing of non-shared SVE state during syscalls. v6: - Rebase onto v5.16-rc1. - Return to disabling TIF_SVE on kernel entry even if we have SME state, this avoids the need for KVM to handle the case where TIF_SVE is set on guest entry. - Add syscall-abi.h to SME updates to syscall-abi, mistakenly omitted from commit. v5: - Rebase onto currently merged SVE and kselftest patches. - Add support for the FA64 option, introduced in the recently published EAC1 update to the specification. - Pull in test program for the syscall ABI previously sent separately with some revisions and add coverage for the SME ABI. - Fix checking for options with 1 bit fields in ID_AA64SMFR0_EL1. - Minor fixes and clarifications to the ABI documentation. v4: - Rebase onto merged patches. - Remove an uneeded NULL check in vec_proc_do_default_vl(). - Include patch to factor out utility routines in kselftests written in assembler. - Specify -ffreestanding when building TPIDR2 test. v3: - Skip FFR rather than predicate registers in sve_flush_live(). - Don't assume a bool is all zeros in sve_flush_live() as per AAPCS. - Don't redundantly specify a zero index when clearing FFR. v2: - Fix several issues with !SME and !SVE configurations. - Preserve TPIDR2 when creating a new thread/process unless CLONE_SETTLS is set. - Report traps due to using features in an invalid mode as SIGILL. - Spell out streaming mode behaviour in SVE ABI documentation more directly. - Document TPIDR2 in the ABI document. - Use SMSTART and SMSTOP rather than read/modify/write sequences. - Rework logic for exiting streaming mode on syscall. - Don't needlessly initialise SVCR on access trap. - Always restore SME VL for userspace if SME traps are disabled. - Only yield to encourage preemption every 128 iterations in za-test, otherwise do a getpid(), and validate SVCR after syscall. - Leave streaming mode disabled except when reading the vector length in za-test, and disable ZA after detecting a mismatch. - Add SME support to vlset. - Clarifications and typo fixes in comments. - Move sme_alloc() forward declaration back a patch.

[PATCH] kselftest: alsa: Add test case for writing invalid values

by Mark Brown

Attempt to write various invalid values for control types we know about and check that something sensible happens. The ABI isn't quite as clearly defined as one might like, rather than generating an error when an invalid value is written many devices will silently rewrite the value into one that is valid for the control. The exact value chosen is not predictable so in the case the write succeeds we just check that the value we read back is one that is valid for the control.

[PATCH v5 00/20] tcp: Initial support for RFC5925 auth option

by Leonard Crestez

This is similar to TCP-MD5 in functionality but it's sufficiently different that packet formats and interfaces are incompatible. Compared to TCP-MD5 more algorithms are supported and multiple keys can be used on the same connection but there is still no negotiation mechanism. Expected use-case is protecting long-duration BGP/LDP connections between routers using pre-shared keys. The goal of this series is to allow routers using the Linux TCP stack to interoperate with vendors such as Cisco and Juniper. Both algorithms described in RFC5926 are implemented but the code is not very easily extensible beyond that. In particular there are several code paths making stack allocations based on RFC5926 maximum, those would have to be increased. Support for arbitrary algorithms was requested in reply to previous posts but I believe there is no real use case for that. The current implementation is somewhat loose regarding configuration: * Overlaping MKTs can be configured despite what RFC5925 says * Current key can be deleted. RFC says this shouldn't be allowed but enforcing this belongs at an admin shell rather than in the kernel. * If multiple keys are valid for a destination the kernel picks one in an unpredictable manner (this can be overridden). These conditions could be tightened but it is not clear the kernel should spend effort to prevent misconfiguration from userspace. The current code is largely feature complete and well-tested but I am somewhat stuck on next steps for getting this into upstream. Any suggestions would be very welcome Here are some known flaws and limitations: * Unsigned packets are sent if AO is active but no keys are found. * Crypto API is used with buffers on the stack and inside struct sock, this might not work on all arches. I'm currently only testing x64 VMs * Interaction with TCP-MD5 not tested in all corners. * Interaction with FASTOPEN not tested and unlikely to work because sequence number assumptions for syn/ack. * No way to limit keys on a per-port basis (used to be implicit with per-socket keys). * Not clear if crypto_ahash_setkey might sleep. If some implementation do that then maybe they could be excluded through alloc flags. * Traffic key is not cached (reducing performance) * No caching or hashing for key lookups so this will scale poorly with many keys There is relatively little code sharing with the TCP_MD5SIG feature and earlier versions shared even less. Unlike MD5 the AO feature is kept separate from the rest of the TCP code and reusing code would require many unrelated cleanup changes. I'm not convinced that "authopt" is particularly good naming convention, this name is a personal invention that does not appear anywhere else. The RFC calls this "tcp-ao". Perhaps TCP_AOSIG would be a better name and it would also make the close connection to TCP_MD5SIG more visible? Some testing support is included in nettest and fcnal-test.sh, similar to the current level of tcp-md5 testing. A more elaborate test suite using pytest and scapy is available out of tree: https://github.com/cdleonard/tcp-authopt-test That test suite is much larger that the kernel code and did not receive many comments in previous ports so I will attempt to push it separately (if at all). Changes for frr (old): https://github.com/FRRouting/frr/pull/9442 That PR was made early for ABI feedback, it has many issues. Changes for yabgp (old): https://github.com/cdleonard/yabgp/commits/tcp_authopt This can be used for easy interoperability testing with cisco/juniper/etc. Would need updates for global keys to avoid leaks Changes since PATCH v4: * Move the traffic_key context_bytes header to stack. If it's a constant string then ahash can fail unexpectedly. * Fix allowing unsigned traffic if all keys are marked norecv. * Fix crashing in __tcp_authopt_alg_init on failure. * Try to respect the rnextkeyid from SYN on SYNACK (new patch) * Fix incorrect check for TCP_AUTHOPT_KEY_DEL in __tcp_authopt_select_key * Improve docs on __tcp_authopt_select_key * Fix build with CONFIG_PROC_FS=n (kernel build robot) * Fix build with CONFIG_IPV6=n (kernel build robot) Link: https://lore.kernel.org/netdev/cover.1640273966.git.cdleonard@gmail.com/ Changes since PATCH v3: * Made keys global (per-netns rather than per-sock). * Add /proc/net/tcp_authopt with a table of keys (not sockets). * Fix part of the shash/ahash conversion having slipped from patch 3 to patch 5 * Fix tcp_parse_sig_options assigning NULL incorrectly when both MD5 and AO are disabled (kernel build robot) * Fix sparse endianness warnings in prefix match (kernel build robot) * Fix several incorrect RCU annotations reported by sparse (kernel build robot) Link: https://lore.kernel.org/netdev/cover.1638962992.git.cdleonard@gmail.com/ Changes since PATCH v2: * Protect tcp_authopt_alg_get/put_tfm with local_bh_disable instead of preempt_disable. This caused signature corruption when send path executing with BH enabled was interrupted by recv. * Fix accepted keyids not configured locally as "unexpected". If any key is configured that matches the peer then traffic MUST be signed. * Fix issues related to sne rollover during handshake itself. (Francesco) * Implement and test prefixlen (David) * Replace shash with ahash and reuse some of the MD5 code (Dmitry) * Parse md5+ao options only once in the same function (Dmitry) * Pass tcp_authopt_info into inbound check path, this avoids second rcu dereference for same packet. * Pass tcp_request_socket into inbound check path instead of just listen socket. This is required for SNE rollover during handshake and clearifies ISN handling. * Do not allow disabling via sysctl after enabling once, this is difficult to support well (David) * Verbose check for sysctl_tcp_authopt (Dmitry) * Use netif_index_is_l3_master (David) * Cleanup ipvx_addr_match (David) * Add a #define tcp_authopt_needed to wrap static key usage because it looks nicer. * Replace rcu_read_lock with rcu_dereference_protected in SNE updates (Eric) * Remove test suite Link: https://lore.kernel.org/netdev/cover.1635784253.git.cdleonard@gmail.com/ Changes since PATCH v1: * Implement Sequence Number Extension * Implement l3index for vrf: TCP_AUTHOPT_KEY_IFINDEX as equivalent of TCP_MD5SIG_FLAG_IFINDEX * Expand TCP-AO tests in fcnal-test.sh to near-parity with md5. * Show addr/port on failure similar to md5 * Remove tox dependency from test suite (create venv directly) * Switch default pytest output format to TAP (kselftest standard) * Fix _copy_from_sockptr_tolerant stack corruption on short sockopts. This was covered in test but error was invisible without STACKPROTECTOR=y * Fix sysctl_tcp_authopt check in tcp_get_authopt_val before memset. This was harmless because error code is checked in getsockopt anyway. * Fix dropping md5 packets on all sockets with AO enabled * Fix checking (key->recv_id & TCP_AUTHOPT_KEY_ADDR_BIND) instead of key->flags in tcp_authopt_key_match_exact * Fix PATCH 1/19 not compiling due to missing "int err" declaration * Add ratelimited message for AO and MD5 both present * Export all symbols required by CONFIG_IPV6=m (again) * Fix compilation with CONFIG_TCP_AUTHOPT=y CONFIG_TCP_MD5SIG=n * Fix checkpatch issues * Pass -rrequirements.txt to tox to avoid dependency variation. Link: https://lore.kernel.org/netdev/cover.1632240523.git.cdleonard@gmail.com/ Changes since RFCv3: * Implement TCP_AUTHOPT handling for timewait and reset replies. Write tests to execute these paths by injecting packets with scapy * Handle combining md5 and authopt: if both are configured use authopt. * Fix locking issues around send_key, introduced in on of the later patches. * Handle IPv4-mapped-IPv6 addresses: it used to be that an ipv4 SYN sent to an ipv6 socket with TCP-AO triggered WARN * Implement un-namespaced sysctl disabled this feature by default * Allocate new key before removing any old one in setsockopt (Dmitry) * Remove tcp_authopt_key_info.local_id because it's no longer used (Dmitry) * Propagate errors from TCP_AUTHOPT getsockopt (Dmitry) * Fix no-longer-correct TCP_AUTHOPT_KEY_DEL docs (Dmitry) * Simplify crypto allocation (Eric) * Use kzmalloc instead of __GFP_ZERO (Eric) * Add static_key_false tcp_authopt_needed (Eric) * Clear authopt_info copied from oldsk in __tcp_authopt_openreq (Eric) * Replace memcmp in ipv4 and ipv6 addr comparisons (Eric) * Export symbols for CONFIG_IPV6=m (kernel test robot) * Mark more functions static (kernel test robot) * Fix build with CONFIG_PROVE_RCU_LIST=y (kernel test robot) Link: https://lore.kernel.org/netdev/cover.1629840814.git.cdleonard@gmail.com/ Changes since RFCv2: * Removed local_id from ABI and match on send_id/recv_id/addr * Add all relevant out-of-tree tests to tools/testing/selftests * Return an error instead of ignoring unknown flags, hopefully this makes it easier to extend. * Check sk_family before __tcp_authopt_info_get_or_create in tcp_set_authopt_key * Use sock_owned_by_me instead of WARN_ON(!lockdep_sock_is_held(sk)) * Fix some intermediate build failures reported by kbuild robot * Improve documentation Link: https://lore.kernel.org/netdev/cover.1628544649.git.cdleonard@gmail.com/ Changes since RFC: * Split into per-topic commits for ease of review. The intermediate commits compile with a few "unused function" warnings and don't do anything useful by themselves. * Add ABI documention including kernel-doc on uapi * Fix lockdep warnings from crypto by creating pools with one shash for each cpu * Accept short options to setsockopt by padding with zeros; this approach allows increasing the size of the structs in the future. * Support for aes-128-cmac-96 * Support for binding addresses to keys in a way similar to old tcp_md5 * Add support for retrieving received keyid/rnextkeyid and controling the keyid/rnextkeyid being sent.

[PATCH v2 0/5] selftests/resctrl: Add resctrl_tests into kselftest set

by Shaopeng Tan

Hello, The aim of this series is to make resctrl_tests run by using kselftest framework. - I modify Makefile of resctrl_test and Makefile of selftest, to build/run resctrl_tests by using kselftest framework. - I set the limited time for resctrl_tests to 120 seconds, to ensure the resctrl_tests finish in limited time. - When resctrl file system is not supported or resctrl_tests is not run as root, return skip code of kselftest. - If it is not finish in limited time, terminate resctrl_tests same as executing ctrl+c. Difference from v1: - I change the order of patches according to Reinette's review. - "LDLIBS + = -lnuma" has no dependencies on this patch series, delete it from [PATCH v2 2/5]. - I separate the license info of Makefile into a new patch [PATCH v2 3/5]. - I separate "limited time" into a new patch [PATCH v2 4/5]. (There is no change in [PATCH v2 1/5] and [PATCH v2 5/5]) In addition, I think 120s is not a problem since some tests have longer timeout (e.g. net test is 300s), please let me know if this is wrong Thanks, Shaopeng Tan (5): selftests/resctrl: Kill the child process created by fork() when the SIGTERM signal comes selftests/resctrl: Make resctrl_tests run using kselftest framework selftests/resctrl: Add license to resctrl_test Makefile selftests/resctrl: Change default limited time to 120 seconds for resctrl_tests selftests/resctrl: Return KSFT_SKIP(4) if resctrlfile system is not supported or resctrl is not run as root tools/testing/selftests/Makefile | 1 + tools/testing/selftests/resctrl/Makefile | 20 +++++++------------ .../testing/selftests/resctrl/resctrl_tests.c | 4 ++-- tools/testing/selftests/resctrl/resctrl_val.c | 1 + tools/testing/selftests/resctrl/settings | 1 + 5 files changed, 12 insertions(+), 15 deletions(-) create mode 100644 tools/testing/selftests/resctrl/settings -- 2.27.0

[PATCH v3 0/6] kunit: refactor assertions to use less stack

by Daniel Latypov

*** BLURB HERE *** Every KUNIT_ASSERT/EXPECT() invocation puts a `kunit_assert` object onto the stack. The most common one is `kunit_binary_assert` which is 88 bytes on UML. So in the cases where the compiler doesn't optimize this away, we can very quickly blow up the stack size. This series implements Linus' suggestion in [1]. Namely, we split out the file, line number, and assert_type (EXPECT/ASSERT) out of kunit_assert. We can also drop the entirely unused `struct kunit *test` field, saving a bit more space as well. All together, sizeof(struct kunit_assert) went from 48 to 24 on UML. Note: the other assert types are bigger, see [2]. This series also adds in an example test that uses all the base KUNIT_EXPECT macros to both advertise their existence to new users and serve as a smoketest for all these changes here. [1] https://groups.google.com/g/kunit-dev/c/i3fZXgvBrfA/m/VULQg1z6BAAJ [2] e.g. consider the most commonly used assert (also the biggest) struct kunit_binary_assert { struct kunit_assert assert; const char *operation; const char *left_text; long long left_value; const char *right_text; long long right_value; }; So sizeof(struct kunit_binary_assert) = went from 88 to 64. I.e. only a 27% reduction instead of 50% in the most common case. All 3 of the `const char*` could be split out into a `static` var as well, but that's a bit trickier to do with how all the macros are written. === Changelog === v1 -> v2: * made the new example test more focused on documenting the macros rather than using them all as a smoketest * s/kunit_failed_assertion()/kunit_do_failed_assertion() * added `unlikely()` to `if(!(pass))` check in KUNIT_ASSERTION() v2 -> v3: * elaborate on intermediate TODO in patch 5 (deleted in patch 6) * update with more Reviewed-by's Daniel Latypov (6): kunit: add example test case showing off all the expect macros kunit: move check if assertion passed into the macros kunit: drop unused kunit* field in kunit_assert kunit: factor out kunit_base_assert_format() call into kunit_fail() kunit: split out part of kunit_assert into a static const kunit: drop unused assert_type from kunit_assert and clean up macros include/kunit/assert.h | 88 +++++++++++----------------------- include/kunit/test.h | 53 ++++++++++---------- lib/kunit/assert.c | 15 ++---- lib/kunit/kunit-example-test.c | 42 ++++++++++++++++ lib/kunit/test.c | 27 +++++------ 5 files changed, 117 insertions(+), 108 deletions(-) base-commit: ad659ccb5412874c6a89d3588cb18857c00e9d0f -- 2.34.1.703.g22d0c6ccf7-goog

[PATCH 0/5] kunit: decrease layers of assertion macros

by Daniel Latypov

Note: this series applies on top of the series reducing stack usage, https://lore.kernel.org/linux-kselftest/20220113165931.451305-1-dlatypov@go… There's no real smenatic dependency between these, just potential for merge conflicts. The current layout of the assertion macros is confusing. Here's the call chain for KUNIT_EXPECT_EQ() and KUNIT_EXPECT_EQ_MSG() KUNIT_EXPECT_EQ => KUNIT_BINARY_EQ_ASSERTION => # note: not shared with the _MSG variant KUNIT_BINARY_EQ_MSG_ASSERTION => KUNIT_BASE_EQ_MSG_ASSERTION => KUNIT_BASE_BINARY_ASSERTION KUNIT_EXPECT_EQ_MSG => KUNIT_BINARY_EQ_MSG_ASSERTION => KUNIT_BASE_EQ_MSG_ASSERTION => KUNIT_BASE_BINARY_ASSERTION After this series KUNIT_EXPECT_EQ => KUNIT_EXPECT_EQ_MSG => KUNIT_BINARY_INT_ASSERTION => KUNIT_BASE_BINARY_ASSERTION The current macro layout tries hard to reduce duplication, but comes at the cost of a lot of intermediates that can simply vanish. The same call-chain again, but annotated with the info we add: KUNIT_EXPECT_EQ => specify we're an EXPECT, not an ASSERT KUNIT_BINARY_EQ_ASSERTION => specify we have a NULL msg KUNIT_BINARY_EQ_MSG_ASSERTION => specify we work with ints, not ptrs KUNIT_BASE_EQ_MSG_ASSERTION => specify that the op is '==' KUNIT_BASE_BINARY_ASSERTION We can see that each level of the chain only specifes one parameter at a time. We've taken the concept of DRY too far. The following is a full snippet of all the macros needed for KUNIT_EXPECT_EQ, showing that a bit of repetition is just fine: #define KUNIT_BINARY_INT_ASSERTION(test, \ assert_type, \ left, \ op, \ right, \ fmt, \ ...) \ KUNIT_BASE_BINARY_ASSERTION(test, \ kunit_binary_assert, \ KUNIT_INIT_BINARY_ASSERT_STRUCT, \ assert_type, \ left, op, right, \ fmt, \ ##__VA_ARGS__) #define KUNIT_EXPECT_EQ(test, left, right) \ KUNIT_EXPECT_EQ_MSG(test, left, right, NULL) #define KUNIT_EXPECT_EQ_MSG(test, left, right, fmt, ...) \ KUNIT_BINARY_INT_ASSERTION(test, \ KUNIT_EXPECTATION, \ left, ==, right, \ fmt, \ ##__VA_ARGS__) as opposed to our current DRYer version #define KUNIT_BASE_EQ_MSG_ASSERTION(test, \ assert_class, \ ASSERT_CLASS_INIT, \ assert_type, \ left, \ right, \ fmt, \ ...) \ KUNIT_BASE_BINARY_ASSERTION(test, \ assert_class, \ ASSERT_CLASS_INIT, \ assert_type, \ left, ==, right, \ fmt, \ ##__VA_ARGS__) #define KUNIT_BINARY_EQ_MSG_ASSERTION(test, assert_type, left, right, fmt, ...)\ KUNIT_BASE_EQ_MSG_ASSERTION(test, \ kunit_binary_assert, \ KUNIT_INIT_BINARY_ASSERT_STRUCT, \ assert_type, \ left, \ right, \ fmt, \ ##__VA_ARGS__) #define KUNIT_BINARY_EQ_ASSERTION(test, assert_type, left, right) \ KUNIT_BINARY_EQ_MSG_ASSERTION(test, \ assert_type, \ left, \ right, \ NULL) #define KUNIT_EXPECT_EQ(test, left, right) \ KUNIT_BINARY_EQ_ASSERTION(test, KUNIT_EXPECTATION, left, right) #define KUNIT_EXPECT_EQ_MSG(test, left, right, fmt, ...) \ KUNIT_BINARY_EQ_MSG_ASSERTION(test, \ KUNIT_EXPECTATION, \ left, \ right, \ fmt, \ ##__VA_ARGS__) Daniel Latypov (5): kunit: make KUNIT_EXPECT_EQ() use KUNIT_EXPECT_EQ_MSG(), etc. kunit: drop unused intermediate macros for ptr inequality checks kunit: reduce layering in string assertion macros kunit: decrease macro layering for integer asserts kunit: decrease macro layering for EQ/NE asserts include/kunit/test.h | 660 ++++++++++--------------------------------- 1 file changed, 142 insertions(+), 518 deletions(-) -- 2.34.1.703.g22d0c6ccf7-goog

[RFC 00/10] drm: selftests: Convert to KUnit

by Michał Winiarski

KUnit unifies the test structure and provides helper tools that simplify the development. Basic use case allows running tests as regular processes, leveraging User Mode Linux. For example, to execute all DRM unit tests: ./tools/testing/kunit/kunit.py run --kunitconfig=drivers/gpu/drm (the tool also allows using QEMU instead of UML by adding e.g. --arch=x86_64) For developers - it means that it's easier to run unit tests on the development machine, tightening the feedback loop. When using UML, it also simplifies using gdb for debug (since the kernel is just a regular process). For CI systems - DRM tests can be moved from being executed on device under test (that's also running IGTs and so on) to being executed on buildsystem during build (just like checkpatch.pl). All tests were renamed - IGT prefix is no longer used. Compared to selftests executed by CI using IGT, there's one functional regression - KUnit test runner is not catching WARNs. To solve this, we could either go in the similar direction that UBSAN went in: 1195505 ("kunit: ubsan integration") Or we could expand the test runner to catch WARN signature in dmesg.

[PATCH V2 00/10] selftests: Fix separate output directory builds

by Muhammad Usama Anjum

Build of several selftests fail if separate output directory is specified by the following methods: 1) make -C tools/testing/selftests O=<build_dir> 2) export KBUILD_OUTPUT="build_dir"; make -C tools/testing/selftests Build fails because of several reasons: 1) The kernel headers aren't found. 2) The path of output objects is wrong and hence unaccessible. These problems can be solved by: 1) Including the correct path of uapi header files 2) By setting the BUILD variable correctly inside Makefile Following different build scenarios have been tested after making these changes to verify that nothing gets broken with these changes: make -C tools/testing/selftests make -C tools/testing/selftests/futex make -C tools/testing/selftests/kvm make -C tools/testing/selftests/landlock make -C tools/testing/selftests/net make -C tools/testing/selftests/net/mptcp make -C tools/testing/selftests/vm make -C tools/testing/selftests O=build make -C tools/testing/selftests o=/opt/build export KBUILD_OUTPUT="/opt/build"; make -C tools/testing/selftests export KBUILD_OUTPUT="build"; make -C tools/testing/selftests cd <any_dir>; make -C <src_path>/tools/testing/selftests cd <any_dir>; make -C <src_path>/tools/testing/selftests O=build --- Changes in V2: Revert the excessive cleanup which was breaking the individual test build.

[PATCH v5 net-next 0/4] Add ethtool interface for RClocks

by Maciej Machnikowski

Synchronous Ethernet networks use a physical layer clock to syntonize the frequency across different network elements. Basic SyncE node defined in the ITU-T G.8264 consist of an Ethernet Equipment Clock (EEC) and have the ability to synchronize to reference frequency sources. This patch series is a prerequisite for EEC object and adds ability to enable recovered clocks in the physical layer of the netdev object. Recovered clocks can be used as one of the reference signal by the EEC. Further work is required to add the DPLL subsystem, link it to the netdev object and create API to read the EEC DPLL state. v5: - rewritten the documentation - fixed doxygen headers v4: - Dropped EEC_STATE reporting (TBD: DPLL subsystem) - moved recovered clock configuration to ethtool netlink v3: - remove RTM_GETRCLKRANGE - return state of all possible pins in the RTM_GETRCLKSTATE - clarify documentation v2: - improved documentation - fixed kdoc warning RFC history: v2: - removed whitespace changes - fix issues reported by test robot v3: - Changed naming from SyncE to EEC - Clarify cover letter and commit message for patch 1 v4: - Removed sync_source and pin_idx info - Changed one structure to attributes - Added EEC_SRC_PORT flag to indicate that the EEC is synchronized to the recovered clock of a port that returns the state v5: - add EEC source as an optiona attribute - implement support for recovered clocks - align states returned by EEC to ITU-T G.781 v6: - fix EEC clock state reporting - add documentation - fix descriptions in code comments Maciej Machnikowski (4): ice: add support detecting features based on netlist ethtool: Add ability to configure recovered clock for SyncE feature ice: add support for monitoring SyncE DPLL state ice: add support for recovered clocks Documentation/networking/ethtool-netlink.rst | 62 ++++ drivers/net/ethernet/intel/ice/ice.h | 7 + .../net/ethernet/intel/ice/ice_adminq_cmd.h | 70 ++++- drivers/net/ethernet/intel/ice/ice_common.c | 224 +++++++++++++++ drivers/net/ethernet/intel/ice/ice_common.h | 20 +- drivers/net/ethernet/intel/ice/ice_devids.h | 3 + drivers/net/ethernet/intel/ice/ice_ethtool.c | 96 +++++++ drivers/net/ethernet/intel/ice/ice_lib.c | 6 +- drivers/net/ethernet/intel/ice/ice_ptp.c | 35 +++ drivers/net/ethernet/intel/ice/ice_ptp_hw.c | 49 ++++ drivers/net/ethernet/intel/ice/ice_ptp_hw.h | 36 +++ drivers/net/ethernet/intel/ice/ice_type.h | 1 + include/linux/ethtool.h | 9 + include/uapi/linux/ethtool_netlink.h | 21 ++ net/ethtool/Makefile | 3 +- net/ethtool/netlink.c | 20 ++ net/ethtool/netlink.h | 4 + net/ethtool/synce.c | 267 ++++++++++++++++++ 18 files changed, 929 insertions(+), 4 deletions(-) create mode 100644 net/ethtool/synce.c -- 2.26.3

[PATCH AUTOSEL 5.10 058/116] selftests/ftrace: make kprobe profile testcase description unique

[PATCH AUTOSEL 5.15 170/188] bpf/selftests: Fix namespace mount setup in tc_redirect

by Sasha Levin

From: Jiri Olsa <jolsa(a)redhat.com> [ Upstream commit 5e22dd18626726028a93ff1350a8a71a00fd843d ] The tc_redirect umounts /sys in the new namespace, which can be mounted as shared and cause global umount. The lazy umount also takes down mounted trees under /sys like debugfs, which won't be available after sysfs mounts again and could cause fails in other tests. # cat /proc/self/mountinfo | grep debugfs 34 23 0:7 / /sys/kernel/debug rw,nosuid,nodev,noexec,relatime shared:14 - debugfs debugfs rw # cat /proc/self/mountinfo | grep sysfs 23 86 0:22 / /sys rw,nosuid,nodev,noexec,relatime shared:2 - sysfs sysfs rw # mount | grep debugfs debugfs on /sys/kernel/debug type debugfs (rw,nosuid,nodev,noexec,relatime) # ./test_progs -t tc_redirect #164 tc_redirect:OK Summary: 1/4 PASSED, 0 SKIPPED, 0 FAILED # mount | grep debugfs # cat /proc/self/mountinfo | grep debugfs # cat /proc/self/mountinfo | grep sysfs 25 86 0:22 / /sys rw,relatime shared:2 - sysfs sysfs rw Making the sysfs private under the new namespace so the umount won't trigger the global sysfs umount.

[PATCH AUTOSEL 5.16 199/217] bpf/selftests: Fix namespace mount setup in tc_redirect

by Sasha Levin

From: Jiri Olsa <jolsa(a)redhat.com> [ Upstream commit 5e22dd18626726028a93ff1350a8a71a00fd843d ] The tc_redirect umounts /sys in the new namespace, which can be mounted as shared and cause global umount. The lazy umount also takes down mounted trees under /sys like debugfs, which won't be available after sysfs mounts again and could cause fails in other tests. # cat /proc/self/mountinfo | grep debugfs 34 23 0:7 / /sys/kernel/debug rw,nosuid,nodev,noexec,relatime shared:14 - debugfs debugfs rw # cat /proc/self/mountinfo | grep sysfs 23 86 0:22 / /sys rw,nosuid,nodev,noexec,relatime shared:2 - sysfs sysfs rw # mount | grep debugfs debugfs on /sys/kernel/debug type debugfs (rw,nosuid,nodev,noexec,relatime) # ./test_progs -t tc_redirect #164 tc_redirect:OK Summary: 1/4 PASSED, 0 SKIPPED, 0 FAILED # mount | grep debugfs # cat /proc/self/mountinfo | grep debugfs # cat /proc/self/mountinfo | grep sysfs 25 86 0:22 / /sys rw,relatime shared:2 - sysfs sysfs rw Making the sysfs private under the new namespace so the umount won't trigger the global sysfs umount.

[PATCH AUTOSEL 5.16 128/217] kunit: Don't crash if no parameters are generated

by Sasha Levin

From: David Gow <davidgow(a)google.com> [ Upstream commit 37dbb4c7c7442dbfc9b651e4ddd4afe30b26afc9 ] It's possible that a parameterised test could end up with zero parameters.

[PATCH AUTOSEL 5.16 117/217] selftests/ftrace: make kprobe profile testcase description unique
