Subject: [PATCH] selftests/seccomp: fix pointer type mismatch in UPROBE test
Date: Sun, 26 Oct 2025 00:19:04 +0530	[thread overview]
Message-ID: <20251025184903.154755-2-nirbhay.lkd@gmail.com> (raw)

Fix compilation error in UPROBE_setup caused by pointer type mismatch
in ternary expression. The probed_uretprobe and probed_uprobe function
pointers have different type attributes (__attribute__((nocf_check))),
which causes the conditional operator to fail with:

  seccomp_bpf.c:5175:74: error: pointer type mismatch in conditional
  expression [-Wincompatible-pointer-types]

Cast both function pointers to 'const void *' to match the expected
parameter type of get_uprobe_offset(), resolving the type mismatch
while preserving the function selection logic.
