util: Fix system call name resolution in syscall_name() debug functionHEADmaster
Fix the starting index, otherwise we miss the first call in sets (say, mknod in filesystem calls). And if we don't find a matching name for the system call, actually return it, instead of trying to fetch it from the current (invalid) call. Fixes: bdbec30a8498 ("seitan: Add netlink, sendto()/sendmsg(), iovec handling, demo with routes") Signed-off-by: Stefano Brivio <sbrivio@redhat.com>
