2021-12-03api: refactor to use REPLY_MSG_ID_BASE #defineKlement Sekera1-8/+5
REPLY_MSG_ID_BASE is the standard way to define reply message id base, so this refactor makes all the files use that. This is a preparation patch for future safety add-ons which rely on REPLY_MACRO* parameters to be preprocessor tokens identifying the message instead, Type: refactor Signed-off-by: Klement Sekera <ksekera@cisco.com> Change-Id: Ibe3e056a3d9326d08af45bbcb25588b11e870141

2021-10-11af_xdp: ensure at least one queue is createdJoshua Roys1-1/+4
Attempting to create an af_xdp interface with zerocopy where the underlying driver didn't support it would lead to a crash due to queue creation silently failing. Type: fix Signed-off-by: Joshua Roys <roysjosh@gmail.com> Change-Id: Ifd9070b8c2b3023d71120c5cf20f7e89d04e4cb3

2021-08-26af_xdp: fix stale rx/tx pointers in xsk objectsBenoît Ganne1-10/+47
xsk objects keep pointers to the rx and tx objects. If we re-allocate the rx and tx vectors after initializing the associated xsk object, the pointers in the xsk object will be staled. To avoid this, we allocate the vectors to the max expected size instead of growing them. Type: fix Change-Id: If30433a28c186787d66c12dbab34bf210c95b519 Signed-off-by: Benoît Ganne <bganne@cisco.com>

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.
