[kamailio] add socket activation support (#293)

by zabbal

Having (optional) support for socket activation in Kamailio would bring several benefits: * Security: systemd can listen on privileged ports or socket paths and start Kamailio with privileges already dropped. * Major upgrades or reconfigurations of Kamailio requiring a full restart are possible without having the listening socket(s) ever go away. * Any service dependent on Kamailio doesn't have to wait for it to finish starting (or start at all). --- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/293

[kamailio/kamailio] core: allow empty matches (#2869)

by Bastian Triller

Anchors like ^ and $ match beginning resp. ending of strings but their matches are zero length, which is ok. The anchors can be used to pre-/append a prefix/suffix via e.g. subst_hf("X-My-Header", "/^/prefix /", "a"); subst_hf("X-My-Header", "/$/ suffix/", "a");   #### 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 - [ ] 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 - [ ] Tested changes locally - [ ] Related to issue #XXXX (replace XXXX with an open issue number) #### Description  You can view, comment on, or merge this pull request online at: https://github.com/kamailio/kamailio/pull/2869 -- Commit Summary -- * <a href="https://github.com/kamailio/kamailio/pull/2869/commits/63190fb0f0580a276146…">core: allow empty matches</a> -- File Changes -- M src/core/data_lump.c (2) M src/core/re.c (4) -- Patch Links -- https://github.com/kamailio/kamailio/pull/2869.patch https://github.com/kamailio/kamailio/pull/2869.diff -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] TLS module: access UID attribute (#1843)

by Sebastian Denz

### Description While implementing an edgeproxy based on kamailio i have to add a custom SIPHeader which contains the uid from the useragents client certificate. The UID is part of the subject like: O = Company CN = Sebastian Denz UID = denz But i cant access that attribute. All i can do is reading the CN and O. ### Expected behavior There should be a select to access the uid Attribute from the subject, or at least a select which returns the whole subject, so it can be parsed manually in kamailio.cfg. #### Actual observed behavior It is only possible to access the O and CN field from the subject. ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` kamailio -v version: kamailio 5.2.0 (x86_64/linux) 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_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 5.3.1 ``` -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Error when parsing P-Asserted-Identity use $ai variable (#2837)

by MikhailKalashnikov

### Description According to RFC 3261 part `7.3.1 Header Field Format` header fields values can be extended over multiple lines separated with tab (`\r\n\t`). It seems that for many headers Kamailio support this format, but for `P-Asserted-Identity` if I try to use variable `$ai` I get error and null value ``` ERROR: |1232432423|<core> [core/parser/parse_addr_spec.c:662]: parse_addr_spec(): unexpected char [] in status 0: [] .

[pai.zip](https://github.com/kamailio/kamailio/files/7071411/pai.zip) And below quotes from RFC 3261 ``` Header fields can be extended over multiple lines by preceding each extra line with at least one SP or horizontal tab (HT) ....

[kamailio/kamailio] Expose the domain in certificate validation errors (#2873)

by Todd

We ran into an issue recently with certificate validation and this modification to the source code helped us quickly identify the root cause. Previously we had no way of seeing which domain was invalid. I didn't like using malloc here but hopefully freeing it in the same context ensures no memory leak as well avoid any memory corruption... with the memcpy and '\0'... hope this helps...   #### Pre-Submission Checklist    - [ ] Commit message has the format required by CONTRIBUTING guide - [ ] Commits are split per component (core, individual modules, libs, utils, ...) - [ ] Each component has a single commit (if not, squash them into one commit) - [ ] 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  You can view, comment on, or merge this pull request online at: https://github.com/kamailio/kamailio/pull/2873 -- Commit Summary -- * <a href="https://github.com/kamailio/kamailio/pull/2873/commits/b7673a8423ed17b78f81…">Expose the domain in certificate validation errors</a> -- File Changes -- M src/modules/tls/tls_util.h (6) -- Patch Links -- https://github.com/kamailio/kamailio/pull/2873.patch https://github.com/kamailio/kamailio/pull/2873.diff -- You are receiving this because you are subscribed to this thread.
