2026-07-24	selftests/bpf: Add simple strscpy() implementation	Ihor Solodrai	1	-0/+4
	commit 63c49efc987afefc6b9bb7de083eb8748e0b1789 upstream. Replace bpf_strlcpy() in bpf_util.h with a sized_strscpy(), which is a simplified sized_strscpy() from the kernel (lib/string.c [1]). It: * takes a count (destination size) parameter * guarantees NULL-termination * returns the number of characters copied or -E2BIG Re-define strscpy macro similar to in-kernel implementation [2]: allow the count parameter to be optional. Add #ifdef-s to tools/include/linux/args.h, as they may be defined in other system headers (for example, __CONCAT in sys/cdefs.h). Fixup the single existing bpf_strlcpy() call in cgroup_helpers.c [1] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/lib/string.c?h=v6.19#n113 [2] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/include/linux/string.h?h=v6.19#n91 Signed-off-by: Ihor Solodrai <ihor.solodrai@linux.dev> Link: https://lore.kernel.org/r/20260223190736.649171-2-ihor.solodrai@linux.dev Signed-off-by: Alexei Starovoitov <ast@kernel.org> Stable-dep-of: 55ffbe8a15b1 ("selftests/bpf: Initialize operation name before use") Signed-off-by: Shung-Hsi Yu <shung-hsi.yu@suse.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2026-07-24	tools/testing: add linux/args.h header and fix radix, VMA tests	Lorenzo Stoakes	1	-0/+28
	commit 9a6a6a3191574a01dcf7a7d9385246d7bc8736bc upstream. Commit 857d18f23ab1 ("cleanup: Introduce ACQUIRE() and ACQUIRE_ERR() for conditional locks") accidentally broke the radix tree, VMA userland tests by including linux/args.h which is not present in the tools/include directory. This patch copies this over and adds an #ifdef block to avoid duplicate __CONCAT declaration in conflict with system headers when we ultimately include this.
