Let's fix it. 05-sim-long_jumps.c: In function ‘main’: 05-sim-long_jumps.c:68:25: warning: implicit declaration of function ‘free’ [-Wimplicit-function-declaration] 68 | free(syscall); Acked-by: Paul Moore <paul@paul-moore.com> Signed-off-by: Tom Hromatka <tom.hromatka@oracle.com> (cherry picked from commit 092c686e1bc4a64d3f876349573ca66144fa3b73)
* tests: improve 05-sim-long_jumps to work better across arch/ABIsPaul Moore2021-11-013-43/+52
| | | | | | | | | | | | | This patch primarily moves the test away from abstract syscall numbers to honest-to-goodness actual syscalls which are present on all currently supported arch/ABIs. This change should make it easier to support this test across different platforms now and moving forward.

| | | | | | | | | | | | | | | | | | | | | | | 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.
