[kamailio/kamailio] CSeqs following the auth transaction are not mangled properly (track_cseq_updates) (#787)
Hi Daniel,
This issue might be related to #679 and #752.
On a "A endpoint" --- Kamailio ---- "B endpoint" scenario with track_cseq_updates enabled, I am having this issue:
- **A** sends INVITE with CSeq 101, **Kamailio** forwards it and gets 407 from **B**.
- **Kamailio** makes the SIP Auth with CSeq 102 using _uac_auth_.
- **A** sends a within-dialog transaction with Cseq 102.
- **Kamailio** does not mangle the Cseq (although it adds P-K-CSeq-Refresh: 103 header).
- **B** sends 200 OK with Cseq 102.
- **Kamailio** mangles it and forwards it to **A** with Cseq 101 (that doesn't match the expected CSeq).
I have tested both in master branch (commit d150d5a) and 4.4 branch (commit 5a21952).
I send you a pcap to your gmail account so that you can see what I mean :)
Thank you and tell me please if you need more testing!
Add here the output of "kamailio -v" with the version from master branch that you are using.
Hi,
Sorry for that, this is the "kamailio -v" output:
``` # kamailio -v version: kamailio 5.0.0-dev6 (x86_64/linux) d150d5 flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: d150d5 compiled on 16:09:08 Sep 19 2016 with gcc 4.7.2 ```
Regards,
Can you grab all the log messages printed by kamailio with debug=3 when processing the request within dialog that doesn't get the cseq updated? Send them to me.
Hi,
Here they are:
- All the logs: https://gist.github.com/cruzccl/c3c0aeede9304caf17708fd84cdcd754
- Just the failing request: https://gist.github.com/cruzccl/ebcb593079a88c9cb3e9c9e3c5489162
Regards,
Can you try with latest master or 4.4 branch and see if works fine? I pushed few patches recently.
Hi Daniel,
Everything seems to work fine after 64a8927 :)
Tested with:
``` version: kamailio 4.4.3 (x86_64/linux) 64a892 flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: 64a892 compiled on 18:07:03 Sep 29 2016 with gcc 4.7.2 ```
Thank you and regards,
Thanks for testing and reporting back.
Closed #787.
