[PATCH bpf-next v2 2/2] selftests/bpf: Add tests for accessing ifindex in bpf_sk_lookup

by Mark Pashmfouroush

A new field was added to the bpf_sk_lookup data that users can access. Add tests that validate that the new ifindex field contains the right data.

[PATCH] Documentation: kunit: fix path to .kunitconfig in start.rst

by Daniel Latypov

Commit ddbd60c779b4 ("kunit: use --build_dir=.kunit as default") changed the default --build_dir, which had the side effect of making `.kunitconfig` move to `.kunit/.kunitconfig`. However, the first few lines of kunit/start.rst never got updated, oops. Fix this by telling people to run kunit.py first, which will automatically generate the .kunit directory and .kunitconfig file, and then edit the file manually as desired.

[PATCH] selftests: exec: unused command-line-argument '-pie'

by Anders Roxell

Building selftests/exec with clang, makes clang warn about the following: clang -Wall -Wno-nonnull -D_GNU_SOURCE -Wl,-z,max-page-size=0x200000 -pie -static load_address.c -o kselftest/exec/load_address_2097152 clang: warning: argument unused during compilation: '-pie' [-Wunused-command-line-argument] Commit 4d1cd3b2c5c1 ("tools/testing/selftests/exec: fix link error") tried to solve the issue, but when fixing the link error by adding '-static', the effect was that no pie binary was created, which makes the test case comletely pointless. The gcc documentation states: '-pie' Produce a dynamically linked position independent executable on targets that support it. For predictable results, you must also specify the same set of options used for compilation ('-fpie', '-fPIE', or model suboptions) when you specify this linker option. Add '-fPIE' to CFLAGS.

[PATCH v8 00/12] syfs: generic deadlock fix with module removal

by Luis Chamberlain

This is a follow up to my v7 series of fixes for the zram driver [0] which ended up uncovering a generic deadlock issue with sysfs and module removal. I've reported this issue and proposed a few patches first since March 2021 [1]. At the end of this email you will find an itemized list of changes since that v1 series, you can also find these changes on my branch 20210927-sysfs-generic-deadlock-fix [4] which is based on linux-next tag next-20210927. Just a heads up, I'm goin on vacation in two days, won't be back until Monday October 11th. On this v8 I incorporate feedback from the v7 series, namely: - Tejun requested I move the struct module to the last attribute when extending functions - As per discussion with Tejun, trimmed and clarified the commit log and documentation on the generic fix on patch 7 - As requested by Bart Van Assche, I simplied the setting of the struct test_config *config into one line instead of two on many places on patch 3 which adds the new sysfs selftest - Dan Williams had some questions about patch 7, and so clarified these questions using a more elaborate example on the commit log to show where the lock call was happening. - Trimmed the Cc list considerably as it was way too long before - Rebased onto linux-next tag next-20210927 Below a list of changes of this patch set since its inception: On v1: - Open coded the sysfs deadlock race to only be localized by the zram driver Changes on v2: - used bdgrab() as well for another race which was speculated by Minchan - improved documentation of fixes Changes on v3: - used a localized zram macros for the sysfs attributes instead of open coding on each routine - replaced bdget() stuff for a generic get_device() and bus_get() on dev_attr_show() / dev_attr_store() for the issue speculated by Michan Changes on v4: - Cosmetic fixes on the zram fixes as requested by Greg - Split out the driver core fix as requested by Greg for the issue speculated by Michan. This fix ended up getting up to its 4th patch iteration [2] and eventually hit linux-next. We got a 0day 0day suspend stres fail for this patch [3] Changes on v5: - I ended up writing a test_sysfs driver and with it I ended up proving that the issue speculated by Michen was not possible and so I asked Greg to drop the patch from his queue titled "sysfs: fix kobject refcount to address races with kobject removal" - checkpatch fixes for the zram changes Changes on v6: - I submitted my test_sysfs driver for inclusion upstream which easily abstracted the deadlock issue in a driver generically [4] - I rebased the zram fixes and added also a new patch for zram to use ATTRIBUTE_GROUPS As per Minchen I sent the patches to be merged through Andrew Morton. - Greg ended up NACK'ing the patchset because he was not sure the fix was correct still Changes on v7: - Formalizes the original proposed generic sysfs fix intead of using macro helpers to work around the issue - I decided it is best to merge all the effort together into one patch set because communication was being lost when I split the patches up. This was not helping in any way to either fix the zram issues or come to consensus on a generic solution. The patches are also merged now because they are all related now. - Running checkpatch exposed that S_IRWXUGO and S_IRWXU|S_IRUGO|S_IXUGO should be replaced, so I did that in this series in two new patches - Adds a try_module_get() documentation extension with tribal knowledge and new information I don't think some folks still believe in. The new test_sysfs selftest however proves this information to be correct, the same selftest can be used to try to prove that documentation incorrect - Because the fix is now generic zram's deadlock can easily be fixed now by just making it use ATTRIBUTE_GROUPS().

[PATCHv3 net 0/5] kselftests/net: add missed tests to Makefile

by Hangbin Liu

When generating the selftest to another folder, some tests are missing as they are not added in Makefile. e.g. make -C tools/testing/selftests/ install \ TARGETS="net" INSTALL_PATH=/tmp/kselftests These pathset add them separately to make the Fixes tags less. It would also make the stable tree or downstream backport easier. If you think there is no need to add the Fixes tag for this minor issue. I can repost a new patch and merge all the fixes together. Thanks v3: no update, just rebase to latest net tree. v2: move toeplitz.sh/toeplitz_client.sh under TEST_PROGS_EXTENDED.

[PATCH] selftests: kselftest.h: mark functions with 'noreturn'

by Anders Roxell

When building kselftests/capabilities the following warning shows up: clang -O2 -g -std=gnu99 -Wall test_execve.c -lcap-ng -lrt -ldl -o test_execve test_execve.c:121:13: warning: variable 'have_outer_privilege' is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized] } else if (unshare(CLONE_NEWUSER | CLONE_NEWNS) == 0) { ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ test_execve.c:136:9: note: uninitialized use occurs here return have_outer_privilege; ^~~~~~~~~~~~~~~~~~~~ test_execve.c:121:9: note: remove the 'if' if its condition is always true } else if (unshare(CLONE_NEWUSER | CLONE_NEWNS) == 0) { ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ test_execve.c:94:27: note: initialize the variable 'have_outer_privilege' to silence this warning bool have_outer_privilege; ^ = false Rework so all the ksft_exit_*() functions have attribue '__attribute__((noreturn))' so the compiler knows that there wont be any return from the function. That said, without '__attribute__((noreturn))' the compiler warns about the above issue since it thinks that it will get back from the ksft_exit_skip() function, which it wont. Cleaning up the callers that rely on ksft_exit_*() return code, since the functions ksft_exit_*() have never returned anything.
