2021-05-21af_xdp: use desc offset on rxBenoît Ganne2-41/+26
Instead of pre-programming the data offset on rx, use offset passed in the descriptor. This is more robust and future-proof. Type: fix Change-Id: I2bd910d92b8b03d17be5be85a24108be711dc7b9 Signed-off-by: Benoît Ganne <bganne@cisco.com>
2021-05-21af_xdp: refill rx rings when interface goes upBenoît Ganne3-9/+26
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 Ganne10-86/+213
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>
2021-05-01vlib: refactor trajectory trace debug featureBenoît Ganne2-12/+18
trajectory trace has been broken for a while because we used to save the buffer trajectory in a vector pointed to in opaque2. This does not work well when opaque2 is copied (eg. because of a clone) as 2 buffers end up sharing the same vector. This dedicates a full cacheline in the buffer metadata instead when trajectory is compiled in. No dynamic allocation, no sharing, no tears.

When using classifier to filter traces, not all packets will be traced. In that case, we should only count traced packets. Type: fix Change-Id: I87d1e217b580ebff8c6ade7860eb43950420ae78 Signed-off-by: Benoît Ganne <bganne@cisco.com>
