2018-08-10IP fragmentation buffer chains, part 2.Ole Troan1-19/+21

2018-08-10vcl: support for eventfd mq signalingFlorin Coras9-69/+249
- support eventfd based mq signaling. Based on configuration, vcl epoll/select can use either condvars or epoll on mq eventfds. - add vcl support for memfd segments - vpp explicitly registers cut-through segments with apps/vcl - if using eventfd, make ldp allow one call to libc_epoll_create. Needed for the message queue epfd - update svm_queue_t to allow blocking calls with eventfd signaling.

2018-08-07Fix dangling reference in l2fib_scan(...)Dave Barach1-0/+8
Deleting a bihash kvp frees the bucket's backing storage when the bucket reference count reaches zero. l2fib_scan MUST check for that condition, and stop scanning the bucket if it occurs. One of the L2 FIB extended "make test" vectors caused this issue 100% of the time. Change-Id: I250bcc4c1518e16042120fbc4032227a759a602e Signed-off-by: Dave Barach <dave@barachs.net>

2018-07-27vcl: use events for epoll/select/read/writeFlorin Coras9-32/+46
Have vcl poll and wait on the event message queues as opposed to constantly polling the session fifos. This also adds event signaling to cut through sessions. On the downside, because we can't wait on multiple condvars, i.e., when we have multiple message queues because of cut-through registrations, we do timed waits.

2018-07-21fix IP directed broadcast node declarationsMatthew Smith2-2/+2
The dev build ('make build') was failing because ip4_rewrite_bcast() and ip6_rewrite_bcast() are declared static and were not referenced. The node functions that were set for directed broadcast rewrite: ip4_rewrite_bcast_node - ip4_rewrite() ip6_rewrite_bcast_node - ip6_rewrite() Changed to: ip4_rewrite_bcast_node - ip4_rewrite_bcast() ip6_rewrite_bcast_node - ip6_rewrite_bcast() The release build ('make build-release') succeeds because there is a VLIB_NODE_FUNCTION_MULTIARCH() call referencing the function. That macro is empty for dev builds. Change-Id: I2a05f00ca43d0eae8ff2e3026991e69917003fe1 Signed-off-by: Matthew Smith <mgsmith@netgate.com>
