Bug ID: 124248
Summary: struct_sock_fprog_sz in ASAN only provided on glibc
Product: gcc
Version: 15.2.0
Status: UNCONFIRMED
Severity: normal

Component: sanitizer

proposed fix
Compiling with `-fsanitize=address` fails on Linux+musl with:
libasan.so: undefined reference to `__sanitizer::struct_sock_fprog_sz'
`struct sock_fprog` is provided by `#include <linux/filter.h>` and not by
glibc, so there is no reason to restrict providing `struct_sock_fprog_sz' to
glibc systems only.
The attached patch fixes the issue.
