[kamailio] inline function suip2a() (ip_addr.h) not working for ipv6 (#379)

by topotomaso

I observed that the inline function suip2a() (ip_addr.h) contains a silly bug and therefor does not work for IPv6 conversions. This silly bug is preventing sip_trace() to work in the onsend_route block for IPv6 sip messages. Rem.: The function suip2a() is used only by the siptrace module. Test background (just for understanding the use case): - using kamailio 4.1.3 (with an additional patch to let onsend_route be called also for replies taken from kamailio 4.2.x) - kamailio is used as loadbalancer in stateless mode (using forward() only) - sip tracing is used by explictly calling sip_trace() in onsend_route, route and onreply routing block to be able to implement an interface specific sip tracing (no SIP transaction based sip tracing is applied by using the siptrace's trace_flag) The silly bug: In suip2a() the function ip6tosbuf() is called with an odd buffer length argument of value "sizeof(buf)-4" which is equal to "IP6_MAX_STR_SIZE -1". ip6tosbuf() however needs at least a buffer length of IP6_MAX_STR_SIZE (otherwise it returns immediately without writing anything into the buffer). So regarding IPv6 adresses the ascii output of suip2a() is alway an empty IPv6 reference ([]). ``` static inline int ip6tosbuf(unsigned char* ip6, char* buff, int len) { int offset; register unsigned char a,b,c; register unsigned char d; register unsigned short hex4; int r; #define HEXDIG(x) (((x)>=10)?(x)-10+'A':(x)+'0') offset=0; if (unlikely(len<IP6_MAX_STR_SIZE)) return 0; ... } #define SUIP2A_MAX_STR_SIZE (IP6_MAX_STR_SIZE + 2 /* [] */ + 1 /* \0 */) /* returns an asciiz string containing the ip * (<ipv4_addr> or [<ipv6_addr>]) */ static inline char* suip2a(union sockaddr_union* su, int su_len) { static char buf[SUIP2A_MAX_STR_SIZE]; int offs; if (unlikely(su->s.sa_family==AF_INET6)){ if (unlikely(su_len<sizeof(su->sin6))) return "<addr. error>"; buf[0]='['; offs=1+ip6tosbuf((unsigned char*)su->sin6.sin6_addr.s6_addr, &buf[1], sizeof(buf)-4); buf[offs]=']'; offs++; }else if (unlikely(su_len<sizeof(su->sin))) return "<addr. error>"; else offs=ip4tosbuf((unsigned char*)&su->sin.sin_addr, buf, sizeof(buf)-2); buf[offs]=0; return buf; } ``` A possible verfied patch looks like this (using this patch sip_trace() is working now as expected in this use case). ``` --- ip_addr.h 2014-04-24 12:02:35.000000000 +0200 +++ ip_addr.h 2015-10-22 18:48:40.553177206 +0200 @@ -737,14 +737,14 @@ return "<addr. error>"; buf[0]='['; offs=1+ip6tosbuf((unsigned char*)su->sin6.sin6_addr.s6_addr, &buf[1], - sizeof(buf)-4); + IP6_MAX_STR_SIZE); buf[offs]=']'; offs++; }else if (unlikely(su_len<sizeof(su->sin))) return "<addr. error>"; else - offs=ip4tosbuf((unsigned char*)&su->sin.sin_addr, buf, sizeof(buf)-2); + offs=ip4tosbuf((unsigned char*)&su->sin.sin_addr, buf, IP4_MAX_STR_SIZE); buf[offs]=0; return buf; } ``` --- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/379

[kamailio] core: fixed passed buffer size in suip2a() (#381)

by topotomaso

- fix regarding issue #379 - it makes sense to backport this fix to 4.2 and 4.3 - Function suip2a() has never worked properly for IPv6 addresses before. The passed buffer size 'sizeof(buf)-4' to ip6tosbuf() was 1 byte to small. So ip6tosbuf() has never written any IPv6 ASCII string to the buffer and therefor suip2a() always returned an empty IPv6 reference string ("[]"). Fixed this by changing passed buffer size to IP6_MAX_STR_SIZE. For similarity also changed uncritical passed buffer size in call to ip4tosbuf() to IP4_MAX_STR_SIZE. The function suip2a() is only used by siptrace module when sip_trace() script function is explicitly called on sending side e.g. in onsend_route block.

[kamailio] Kamailio not compiling - systemd/sd-journal.h: No such file or directory (#380)

When trying to compile Kamailio, I get the following error: ``` CC (gcc) [M log_systemd.so] log_systemd_mod.o [91mlog_systemd_mod.c:27:32: fatal error: systemd/sd-journal.h: No such file or directory [0m[91mcompilation terminated.

This is an automated Jenkins/Docker build that was previously succeeding, so that rules out the dependency problems.

Use rtpengine lua question

by Yuriy Gorlichenko

Hello. I want to rewrite some my configs by using lua scripts. At examples I saw that I can use constructions like sr.some_module.module_api("options") Can I use with this method rtpengine module api because many of projects that I have uses Webrtc and use rtpengine and ofcourse I dont want "to jump" from config file to scripts.
