[kamailio/kamailio] nathelper: fixed handle_ruri_alias() for alias being an IPv6 (PR #3913)
by Dragos Vingarzan 15 Jul '24

#### Pre-Submission Checklist    - [x] Commit message has the format required by CONTRIBUTING guide - [x] Commits are split per component (core, individual modules, libs, utils, ...) - [x] Each component has a single commit (if not, squash them into one commit) - [x] No commits to README files for modules (changes must be done to docbook files in `doc/` subfolder, the README file is autogenerated) #### Type Of Change - [x] Small bug fix (non-breaking change which fixes an issue) - [ ] New feature (non-breaking change which adds new functionality) - [ ] Breaking change (fix or feature that would change existing functionality) #### Checklist:  - [ ] PR should be backported to stable branches - [x] Tested changes locally - [ ] Related to issue #XXXX (replace XXXX with an open issue number) #### Description  `handle_ruri_alias()` wasn't handling correctly the IP address in the alias, in case it was an IPv6. This adds `[` and `]` around the IP if v6 when composing a destination SIP URI, such that the downstream functions will handle it correctly and not be confused by the `:` before the port. Arguably, nathelper is not needed in IPv6. Yet I have discovered a scenario where it could be quite helpful as a way to force some UE routing through an intermediary proxy.

[kamailio/kamailio] Debian package build fails for Kamailio 5.7.4 (Issue #3722)
by Alexander Bakker 15 Jul '24

15 Jul '24

### Description The Debian package build fails for Kamailio 5.7.4 because it can't find static libssl. This happens because ``LIBSSL_STATIC_SRCPATH`` is set to the wrong location in the rules file. ### Troubleshooting #### Reproduction 1. Run ``ln -s pkg/kamailio/deb/bookworm debian`` 2. Run ``make deb`` #### Output ``` gcc -shared -g -m64 -Wl,-O2 -Wl,-E -Wl,-z,relro -pthread -rdynamic "-ldl" -Wl,-Bsymbolic-functions tls_bio.o tls_cfg.o tls_config.o tls_ct_wrq.o tls_domain.o tls_dump_vf.o tls_init.o tls_locking.o tls_map.o tls_rand.o tls_rpc.o tls_select.o tls_server.o tls_util.o tls_verify.o tlsa_mod.o -lm /usr/lib64/libssl.a /usr/lib64/libcrypto.a -o tlsa.so /usr/bin/ld: cannot find /usr/lib64/libssl.a: No such file or directory /usr/bin/ld: cannot find /usr/lib64/libcrypto.a: No such file or directory collect2: error: ld returned 1 exit status make[5]: *** [../../Makefile.rules:191: tlsa.so] Error 1 ``` ### Possible Solutions An extremely hacky workaround is to patch the rules file to point ``LIBSSL_STATIC_SRCPATH`` to the right location: ``` sed -i -e "/LIBSSL_STATIC_SRCPATH/a export\\ LIBSSL_STATIC_SRCPATH=\\/usr\\/lib\\/$(uname -m)-linux-gnu" pkg/kamailio/deb/bookworm/rules ``` ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.7.4 (x86_64/linux) flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MMAP, PKG_MALLOC, MEM_JOIN_FREE, 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_BLOCKLIST, HAVE_RESOLV_RES, TLS_PTHREAD_MUTEX_SHARED ADAPTIVE_WAIT_LOOPS 1024, MAX_RECV_BUFFER_SIZE 262144, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: unknown compiled with gcc 12.2.0 ``` * **Operating System**: ``` Distributor ID: Debian Description: Debian GNU/Linux 12 (bookworm) Release: 12 Codename: bookworm ``` ``` Linux 6.5.0-14-generic #14-Ubuntu SMP PREEMPT_DYNAMIC Tue Nov 14 14:59:49 UTC 2023 x86_64 GNU/Linux ``` -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3722 You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] No CDR is written on failover (Issue #3254)
by Earn330 15 Jul '24

15 Jul '24

Hi, I think there is an issue with writing CDRs on failover scenarios. I have two servers with Kamailio. Both server running Debian 11 (bulleye) and latest Kamailio 5.6.1 from git. I'm using DMQ to sync dialogs and htable between these servers, so both servers have the same knowledge of dialog state. Both Kamailio uses nobind option, so I can switch a VIP from one server to the other one. This is managed with keepalived. Switching the VIP from one server the other one works fine an while a call is running I can switch the VIP. I can see that the BYE Message is handled OK after I made a switch. I can see that acc is triggered but what is missing is acc_cdr in this case. I'm using htable to fill all necessary variables to complete the CDR an I can see that all values are synced correctly. The acc_cdr is created fine if there is no failover so i think it can't be an configuration issue. Both server holds the same Kamailio configuration except the IP. `version: kamailio 5.6.1 (x86_64/linux) bfc5c2-dirty flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, 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_BLOCKLIST, HAVE_RESOLV_RES, TLS_PTHREAD_MUTEX_SHARED ADAPTIVE_WAIT_LOOPS 1024, MAX_RECV_BUFFER_SIZE 262144, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: bfc5c2 -dirty compiled with gcc 10.2.1` `root@voip-lab-proxy01:~# lsb_release -a No LSB modules are available.
