Commit Message

system: use old SECCOMP_IOCTL_NOTIF_ID_VALID number if necessary

Kernel commit 47e33c05f9f0 ("seccomp: Fix ioctl number for
SECCOMP_IOCTL_NOTIF_ID_VALID") changed the public definition of
SECCOMP_IOCTL_NOTIF_ID_VALID for correctness sake because it had the
wrong direction (no current functional change). If libseccomp is built
against kernel headers after this commit but is run on a kernel that was
built prior to this commit, then the ioctl will always return -1 EINVAL
and thus seccomp_notify_id_valid will incorrectly return -ENOENT.

Copy the (now non-public) definition of the old ioctl number and try it
if the ioctl with the number from the kernel headers fails with -1
EINVAL.

Also, update the fallback definition of SECCOMP_IOCTL_NOTIF_ID_VALID to
the new value.
