[kamailio/kamailio] Problems establishing SIP signaling between MsTeams and Kamailio. (#2597)
by wvalles3010 06 Jan '21

06 Jan '21

Hello community, I am having trouble establishing SIP signaling between MsTeams and Kamailio. I currently have this configuration in my tls.cfg file [server: default] method = TLSv1.2 + verify_certificate = yes require_certificate = yes private_key = /etc/kamailio/certificates/private-key.pem certificate = /etc/kamailio/certificates/certificate.pem [client: default] method = TLSv1.2 + verify_certificate = yes require_certificate = yes private_key = /etc/kamailio/certificates/private-key.pem certificate = /etc/kamailio/certificates/certificate.pem My domain was certified with ssl through an authoritative certifier (GoDaddy), however I see these errors in the / var / log / messages of the Kamailio server.

[kamailio/kamailio] dialog flag vs dlg_manage() - flag doesn't store uac_replace_* dialog variables (#2593)
by Sergiu Pojoga 05 Jan '21

05 Jan '21

### Description When invoking dialog tracking by flag instead of dlg_manage(), dialog doesn't store uac_replace_* variables. As a result, uac restore functionality doesn't work. ### Troubleshooting #### Reproduction #!define FLT_DIALOG 4 ... modparam("dialog", "dlg_flag", FLT_DIALOG) ... request_route { if (is_method("INVITE")) setflag(FLT_DIALOG); ... } Make a call. List dialogs (kamcmd dlg.list) You'll notice the dialog has no _uac_ variables  #### Debugging Data  ``` (paste your debugging data here) ``` #### Log Messages  ``` (paste your log messages here) ``` #### SIP Traffic  ``` (paste your sip traffic here) ``` ### Possible Solutions  ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.3.8 (x86_64/linux) a58155 ``` * **Operating System**:  ``` NAME="Debian GNU/Linux" VERSION="8 (jessie)" ``` -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] Fix 2 issues that prevent auto_bind_ipv6 from happening on my setup (#2595)
by Paul Komkoff 05 Jan '21

05 Jan '21

#### 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: - [x] PR should be backported to stable branches - [x] Tested changes locally - [ ] Related to issue #XXXX (replace XXXX with an open issue number) #### Description Without the first commit, on my setup - which has lots of interfaces with lots of addresses - auto_bind_ipv6 will make kamailio stuck on startup. It actually happens in get_flags, where data sent back from kernel can't fit into 8K anymore. Second commit is fixing obvious typo while we're at it.

git:master:d2fd204b: core: work around interface enum buffer overrun

Module: kamailio Branch: master Commit: d2fd204b0ae35512a04702e480bb0d16878e98be URL: https://github.com/kamailio/kamailio/commit/d2fd204b0ae35512a04702e480bb0d1… Author: Paul Komkoff <i(a)stingr.net> Committer: Paul Komkoff <i(a)stingr.net> Date: 2021-01-05T14:55:04+04:00 core: work around interface enum buffer overrun When a system has too many interfaces and too many addresses, 8 kilobytes isn't enough to fit all of the netlink responses. As the result, kamailio gets stuck in a loop where it tries to do a 0-length recv. Increase the buffer to 32K. It's a miniscule amount for modern times anyway. Also, add diagnostics to make further troubleshooting easier. Proper fix would be to switch to libnl here, which would make a good weekend project. --- Modified: src/core/socket_info.c --- Diff: https://github.com/kamailio/kamailio/commit/d2fd204b0ae35512a04702e480bb0d1… Patch: https://github.com/kamailio/kamailio/commit/d2fd204b0ae35512a04702e480bb0d1… --- diff --git a/src/core/socket_info.c b/src/core/socket_info.c index a46aba24ad..d34f3fb4cd 100644 --- a/src/core/socket_info.c +++ b/src/core/socket_info.c @@ -1070,6 +1070,7 @@ static int nl_bound_sock(void) req.g.rtgen_family = family;\ } while(0); +#define NETLINK_BUFFER_SIZE 32768 static int get_flags(int family){ struct { @@ -1079,7 +1080,7 @@ static int get_flags(int family){ int rtn = 0; struct nlmsghdr* nlp; struct ifinfomsg *ifi; - char buf[8192]; + char buf[NETLINK_BUFFER_SIZE]; char *p = buf; int nll = 0; int nl_sock = -1; @@ -1095,6 +1096,10 @@ static int get_flags(int family){ } while(1) { + if ((sizeof(buf) - nll) == 0) { + LM_ERR("netlink buffer overflow in get_flags"); + goto error; + } rtn = recv(nl_sock, p, sizeof(buf) - nll, 0); nlp = (struct nlmsghdr *) p; if(nlp->nlmsg_type == NLMSG_DONE){ @@ -1148,7 +1153,7 @@ static int build_iface_list(void) struct nlmsghdr* nlp; struct ifaddrmsg *ifi; int rtl; - char buf[8192]; + char buf[NETLINK_BUFFER_SIZE]; char *p = buf; int nll = 0; struct rtattr * rtap; @@ -1184,6 +1189,10 @@ static int build_iface_list(void) nll = 0; p = buf; while(1) { + if ((sizeof(buf) - nll) == 0) { + LM_ERR("netlink buffer overflow in build_iface_list"); + goto error; + } rtn = recv(nl_sock, p, sizeof(buf) - nll, 0); LM_DBG("received %d byles \n", rtn); nlp = (struct nlmsghdr *) p;
