selftests: af_unix: add USER_NS config [ Upstream commit f8b1abed736111f914b2c567d9a3db1f71e788e8 ] This is required to use unshare(CLONE_NEWUSER). This has not been seen on NIPA before, because the 'af_unix' tests are executed with the 'net' ones, merging their config files. USER_NS is present in tools/testing/selftests/net/config. This issue is visible when only the af_unix config is used on top of the default one. This is the recommended way to execute selftest targets.

af_unix: selftest: Fix the size of the parameter to connect() Adjust size parameter in connect() to match the type of the parameter, to fix "No such file or directory" error in selftests/net/af_unix/ test_oob_unix.c:127. The existing code happens to work provided that the autogenerated pathname is shorter than sizeof (struct sockaddr), which is why it hasn't been noticed earlier. Visible from the trace excerpt: bind(3, {sa_family=AF_UNIX, sun_path="unix_oob_453059"}, 110) = 0 clone(child_stack=NULL, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD, child_tidptr=0x7fa6a6577a10) = 453060 [pid <child>] connect(6, {sa_family=AF_UNIX, sun_path="unix_oob_45305"}, 16) = -1 ENOENT (No such file or directory) BUG: The filename is trimmed to sizeof (struct sockaddr).

selftests: net: af_unix: Fix a build error of unix_connect.c. This patch fixes a build error reported in the link. [0] unix_connect.c: In function ‘unix_connect_test’: unix_connect.c:115:55: error: expected identifier before ‘(’ token #define offsetof(type, member) ((size_t)&((type *)0)->(member)) ^ unix_connect.c:128:12: note: in expansion of macro ‘offsetof’ addrlen = offsetof(struct sockaddr_un, sun_path) + variant->len; ^~~~~~~~ We can fix this by removing () around member, but checkpatch will complain about it, and the root cause of the build failure is that I followed the warning and fixed this in the v2 -> v3 change of the blamed commit. [1] CHECK: Macro argument 'member' may be better as '(member)' to avoid precedence issues #33: FILE: tools/testing/selftests/net/af_unix/unix_connect.c:115: +#define offsetof(type, member) ((size_t)&((type *)0)->member) To avoid this warning, let's use offsetof() defined in stddef.h instead.
