by Hangbin Liu

Currently the temporary address is not removed when mngtmpaddr is deleted or becomes unmanaged. The patch set fixed this issue and add a related test. v2: 1) delete the tempaddrs directly instead of remove them in addrconf_verify_rtnl(Sam Edwards) 2) Update the test case by checking the address including, add Sam in SOB (Sam Edwards) Hangbin Liu (2): net/ipv6: delete temporary address if mngtmpaddr is removed or unmanaged selftests/rtnetlink.sh: add mngtempaddr test net/ipv6/addrconf.c | 41 +++++++--- tools/testing/selftests/net/rtnetlink.sh | 95 ++++++++++++++++++++++++ 2 files changed, 124 insertions(+), 12 deletions(-) -- 2.46.0

[PATCH v2] selftests: Warn about skipped tests in result summary

Update the functions that print the test totals at the end of a selftest to include a warning message when skipped tests are detected. The message advises users that skipped tests may indicate missing configuration options and suggests enabling them to improve coverage.

[PATCH kselftest] fix single bpf test

by Jiayuan Chen

Currently, when testing a certain target in selftests, executing the command 'make TARGETS=XX -C tools/testing/selftests' succeeds for non-BPF, but a similar command fails for BPF: ''' make TARGETS=bpf -C tools/testing/selftests make: Entering directory '/linux-kselftest/tools/testing/selftests' make: *** [Makefile:197: all] Error 1 make: Leaving directory '/linux-kselftest/tools/testing/selftests' ''' The reason is that the previous commit: commit 7a6eb7c34a78 ("selftests: Skip BPF seftests by default") led to the default filtering of bpf in TARGETS which make TARGETS empty. That commit also mentioned that building BPF tests requires external commands to run. This caused target like 'bpf' or 'sched_ext' defined in SKIP_TARGETS to need an additional specification of SKIP_TARGETS as empty to avoid skipping it, for example: ''' make TARGETS=bpf SKIP_TARGETS="" -C tools/testing/selftests ''' If special steps are required to execute certain test, it is extremely unfair. We need a fairer way to treat different test targets. This commit provider a way: If a user has specified a single TARGETS, it indicates an expectation to run the specified target, and thus the object should not be skipped. Another way is to change TARGETS to DEFAULT_TARGETS in the Makefile and then check if the user specified TARGETS and decide whether filter or not, though this approach requires too many modifications.

[PATCH AUTOSEL 6.6 14/16] selftests/resctrl: Protect against array overflow when reading strings

by Sasha Levin

From: Reinette Chatre <reinette.chatre(a)intel.com> [ Upstream commit 46058430fc5d39c114f7e1b9c6ff14c9f41bd531 ] resctrl selftests discover system properties via a variety of sysfs files. The MBM and MBA tests need to discover the event and umask with which to configure the performance event used to measure read memory bandwidth. This is done by parsing the contents of /sys/bus/event_source/devices/uncore_imc_<imc instance>/events/cas_count_read Similarly, the resctrl selftests discover the cache size via /sys/bus/cpu/devices/cpu<id>/cache/index<index>/size. Take care to do bounds checking when using fscanf() to read the contents of files into a string buffer because by default fscanf() assumes arbitrarily long strings. If the file contains more bytes than the array can accommodate then an overflow will occur. Provide a maximum field width to the conversion specifier to protect against array overflow. The maximum is one less than the array size because string input stores a terminating null byte that is not covered by the maximum field width.
