2019-09-30session: move ctrl messages from bapi to mqFlorin Coras9-106/+675
Type:refactor Moves connect, disconnect, bind, unbind and app detach to message queue from binary api. Simplifies app/vcl interaction with the session layer since all session control messages are now handled over the mq. Add/del segment messages require internal C api changes which affect all builtin applications. They'll be moved in a different patch and might not be back portable to 19.08.

2019-09-25interface: use the correct condition for checking if the pcap fd is openAndrew Yourtchenko3-3/+3
The 9af7e2e87e used a comparison that fd is >= 0 to check that the pcap needs closing. While the pcap_close() function does reset the file descriptor to -1, the freshly initialized structure has it equal to 0. This causes the VPP to close stdin if the packets are being seen on pg interface without the capture file being opened. This triggers the vpp attempting to read from STDIN (another bug), which results in running out of memory.

2019-09-25interface: fix pcap_write functionAndrew Yourtchenko2-1/+6
when use pcap cli to capture pcakets into two files rx01.pcap && rx02.pcap, the first time: 1)pcap rx trace on max 100 intfc any file rx01.pcap 2)......the process of capture data to buffer...... 3)pcap rx trace off the second time: 4)pcap rx trace on max 100 intfc any file rx02.pcap 5)......the process of capture data to buffer...... 6)pcap rx trace off the pcap_write function bug in this two lines pm->n_packets_captured = 0; if (pm->n_packets_captured >= pm->n_packets_to_capture) referring to calling pcap_close() will result in that the twice pcap cli both writes the packets into rx01.pcap, but nothing into rx02.pcap. Beside, the rx02.pcap file will not be created. solution: separate the pcap_close() out of pcap_write() The automatic cherrypick did not work, so the manual cherrypick of commit 9af7e2e87e6a11fb69309fc9ce4432acbc4e3 was performed as follows: 0) git checkout stable/1908 1) git checkout -b stable-1908-history-rewrite 2) git rebase -i d1e17d00bb81659bf9e45caa62482bf7029d98f7~1 3) in the editor, mark the second commit as "edit", search for the following commits and edit as in the snippet below: edit 30d28bdfd api: enforce vla is last and fixed string type drop 4c19bfd93 vlib: clean up the "pcap dispatch trace" debug CLI pick 4aef0dd82 dpdk: fix extended stats edit 1dafb7fd8 dpdk: initialize rte_mbuf during mempool dequeue drop 4b943d632 misc: clean up "pcap [rx|tx] trace" debug CLI 4) close the editor 5) git cherry-pick 9af7e2e87e6a11fb69309fc9ce4bf8432acbc4e3 (it applies cleanly) 6) git rebase --continue (rebase of a 1000+ patches) 7) at prompt - git cherry-pick -x e5948fb49a6eeaf437323cc1043a350cd33bcd47 8) git rebase --continue 9) at prompt - git cherry-pick -x b97641c79f4aaf0069268c550f263167ddea2b34 10) git rebase --continue 11) the rebase finished. 12) git checkout stable/1908 13) git diff stable/1908..stable-1908-history-rewrite | patch -p1 14) discard the whitespace-only hunk 15) git commit -a -s; edit this commit message Type: fix Change-Id: Iedeb46f9cf0a4cb12449fd75a4014f95f3bb3fa8 Signed-off-by: Jack Xu <jack.c.xu@ericsson.com> Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>
