2019-09-25interface: fix pcap_write functionAndrew Yourtchenko1-3/+0
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>
