We hit the following build error while running the seccomp selftests in
our testing.
CC seccomp_bpf
seccomp_bpf.c: In function ‘UPROBE_setup’:
seccomp_bpf.c:5175:74: error: pointer type mismatch in conditional expression
[-Wincompatible-pointer-types]
5175 | offset = get_uprobe_offset(variant->uretprobe ? probed_uretprobe :
probed_uprobe);
| ^
seccomp_bpf.c:5175:57: note: first expression has type ‘int (*)(void)’
5175 | offset = get_uprobe_offset(variant->uretprobe ? probed_uretprobe :
probed_uprobe);
| ^~~~~~~~~~~~~~~~
seccomp_bpf.c:5175:76: note: second expression has type ‘int
(__attribute__((nocf_check)) *)(void)’
5175 | offset = get_uprobe_offset(variant->uretprobe ? probed_uretprobe :
probed_uprobe);
| ^~~~~~~~~~~~~
get_uprobe_offset() takes a 'const void *' argument, so cast both
operands to 'void *'.
Fixes: 9ffc7a635c35 ("selftests/seccomp: validate uprobe syscall passes through
seccomp")
