2021-05-21af_xdp: refill rx rings when interface goes upBenoît Ganne1-0/+2
If interrupt mode is configured through startup.conf exec script, the input function will not be polled and the rx ring will never be filled. Always refill the ring when interface goes up so it is ready to receive packets. Type: fix Change-Id: I4cf22c8ae00638679f2e8650303a6fe916c1319b Signed-off-by: Benoît Ganne <bganne@cisco.com>
2021-05-21af_xdp: workaround kernel race between poll() and sendmsg()Benoît Ganne1-6/+24
Prior to Linux 5.6 there is a race condition between poll() and sendmsg() in the kernel. This patch protects the syscalls with a lock to prevent it, unless the NO_SYSCALL_LOCK flag is set at create time. See https://lore.kernel.org/bpf/BYAPR11MB365382C5DB1E5FCC53242609C1549@BYAPR11MB3653.namprd11.prod.outlook.com/ Type: fix Change-Id: Ie7d4f5cb41f697b11a09b6046e54d190430d76df Signed-off-by: Benoît Ganne <bganne@cisco.com>
