52035628 - selftests: fix header dependency for pid_namespace selftests

Thu, 24 Mar 2022 22:39:28 +0000

selftests: fix header dependency for pid_namespace selftestsThe way the test target was defined before, when building with clang weget a command line like this:clang -Wall -Werror -g -I../../../../usr/include/ \ regression_enomem.c ../pidfd/pidfd.h -o regression_enomemThis yields an error, because clang thinks we want to produce both a *.ofile, as well as a precompiled header:clang: error: cannot specify -o when generating multiple output filesgcc, for whatever reason, doesn't exhibit the same behavior which Isuspect is why the problem wasn't noticed before.This can be fixed simply by using the LOCAL_HDRS infrastructure theselftests lib.mk provides. It does the right think and marks the targetas depending on the header (so if the header changes, we rebuild), butit filters the header out of the compiler command line, so we don't getthe error described above.Signed-off-by: Axel Rasmussen Reviewed-by: Christian Brauner Signed-off-by: Shuah Khan List of files: /linux-6.15/tools/testing/selftests/pid_namespace/Makefile

6952a4f6 - selftests: add pid namespace ENOMEM regression test

Sun, 08 Mar 2020 16:26:32 +0000

selftests: add pid namespace ENOMEM regression testWe recently regressed (cf. [1] and its corresponding fix in [2]) returningENOMEM when trying to create a process in a pid namespace whose initprocess/child subreaper has already died. This has caused confusion atleast once before that (cf. [3]). Let's add a simple regression test tocatch this in the future.[1]: 49cb2fc42ce4 ("fork: extend clone3() to support setting a PID")[2]: b26ebfe12f34 ("pid: Fix error return value in some cases")[3]: 35f71bc0a09a ("fork: report pid reservation failure properly")Cc: Corey Minyard Cc: Oleg Nesterov Cc: Adrian Reber Cc: Dmitry Safonov <0x7f454c46@gmail.com>Cc: Andrei Vagin Signed-off-by: Christian Brauner List of files: /linux-6.15/tools/testing/selftests/pid_namespace/Makefile
