2019-12-30vcl: hold errno when calling LDBGhanlin1-1/+5
Type: fix Call trace of LDBG: LDBG->clib_warning->_clib_error->dispatch_message->os_puts->writev However, writev will hijacked by LDP, and then execute following code: if ((errno = -ldp_init ())) return -1; Now, errno will be set. Because we always call LDBG just before return from ldp_accept4, listen, and etc. So errno will be overwritted after LDBG called.

2019-11-14vcl: Handle newer Glibc (>2.28) where fcntl is actually fcntl64Carl Smith1-0/+9
Glibc 2.28 now provides fcntl64 which is used instead of fcntl by defining fcntl as fcntl64 in fcntl.h Type: fix Change-Id: I87fedfbf3e0d241aafdc920e90f824d71353e0e6 Signed-off-by: Carl Smith <carl.smith@alliedtelesis.co.nz>
2019-08-21vcl: fix ldp_set_app_name overflowBenoît Ganne1-5/+2
In case of overflow, we null-terminate the parameter ('app_name') instead of ldp global name ('ldp->app_name'). Moreover, snprintf() always safely null-terminate the destination string even in case of overflow.

2019-02-19ldp: return byte count from a successful recvfromHaggai Eran1-2/+6
Unless there's an error, recvfrom should return the number of bytes received. The current code returns zero on success due to ldp_copy_ep_to_sockaddr returning zero. Change-Id: Ib843b99a08c44b5ee2d16efe9edab0cf5df65170 Signed-off-by: Haggai Eran <haggai.eran@gmail.com>

2019-01-07vcl/ldp: add locked sessions shim layerFlorin Coras1-1284/+336
Moves LDP logic that allows sharing of sessions between multi-process app workers into a separate VCL shim layer. Also refactors LDP to use the new layer. Change-Id: I8198b51eae7d099a8c486e36b29e3a0cb8cee8e9 Signed-off-by: Florin Coras <fcoras@cisco.com>
2019-01-05vcl/session: add api for changing session app workerFlorin Coras1-105/+159
In case of multi process apps, after forking, the parent may decide to close part or all of the sessions it shares with the child. Because the sessions have fifos allocated in the parent's segment manager, they must be moved to the child's segment manager.

2018-08-10vcl: support for eventfd mq signalingFlorin Coras1-221/+197
- 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.

2018-07-27vcl: use events for epoll/select/read/writeFlorin Coras1-1/+1
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.
