+Subject: libbpf: Fix -Wdiscarded-qualifiers under C23
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+commit d70f79fef65810faf64dbae1f3a1b5623cdb2345 upstream.
+
+glibc ≥ 2.42 (GCC 15) defaults to -std=gnu23, which promotes
+-Wdiscarded-qualifiers to an error.
+
+In C23, strstr() and strchr() return "const char *".
+
+Change variable types to const char * where the pointers are never
+modified (res, sym_sfx, next_path).

+[ shung-hsi.yu: needed to fix kernel build failure due to libbpf since glibc
+ 2.43+ (which adds 'const' qualifier to strstr). 'sym_sfx' hunk dropped because
+ commit f8a05692de06 ("libbpf: Work around kernel inconsistently stripping
+ '.llvm.' suffix") is not present. ]

A recent change in oe-core [1] to glibc 2.43 has introduced a build error with 6.12 kernels. Backport a patch [2] from linux-stable to address this.
