[PATCH net] selftests: tc-testing: fix nat regex matching

by Pedro Tammela

In iproute 6.14, the nat ip mask logic was fixed to remove a undefined behaviour. So now instead of reporting '0.0.0.0/32' on x86 and potentially '0.0.0.0/0' in other platforms, it reports '0.0.0.0/0' in all platforms.

[RFC PATCH] rtc: remove 'setdate' test program

[PATCH] selftest: rtc: skip some tests if the alarm only supports minutes

by Wolfram Sang

There are alarms which have only minute-granularity. The RTC core already has a flag to describe them. Use this flag to skip tests which require the alarm to support seconds. Signed-off-by: Wolfram Sang <wsa+renesas(a)sang-engineering.com> --- Tested with a Renesas RZ-N1D board. This RTC obviously has only minute resolution for the alarms. Output now looks like this: # RUN rtc.alarm_alm_set ... # SKIP Skipping test since alarms has only minute granularity. # OK rtc.alarm_alm_set ok 5 rtc.alarm_alm_set # SKIP Skipping test since alarms has only minute granularity.
