I added the ability to get socket info in this route block. Now added ``` $siptrace(src_uri) $siptrace(dst_uri) ``` This pseudovars return string like ``` udp:8.8.8.8:5060 ``` I think `src_uri` and `dst_uri` is not correct here because this socket info, not SIP uri. I expecting suggestion on how to get these params and from current implementation: ``` src_ip src_port src_proto dst_ip dst_port dst_proto ``` As reference, I take `sipdump` pseudovariable You can view, comment on, or merge this pull request online at: https://github.com/kamailio/kamailio/pull/2752 -- Commit Summary -- * siptrace: aadded siptrace pseudo var -- File Changes -- M src/modules/siptrace/siptrace.c (72) -- Patch Links -- https://github.com/kamailio/kamailio/pull/2752.patch https://github.com/kamailio/kamailio/pull/2752.diff -- You are receiving this because you are subscribed to this thread.

[kamailio/kamailio] app_perl: Ignore __DIE__ signals that come from eval blocks (#2745)
by rodolfojcj 09 Jun '21

09 Jun '21

### Description If possible, I would like that the `kamailio/src/modules/app_perl/lib/perl/Kamailio.pm` file does not generate error messages to the system log files, which are not actual errors and are caused by `eval` blocks of third-party Perl modules that my code depends on. To illustrate the current setup, let's consider the following: - In file `/etc/kamailio/kamailio_52.cfg` ```perl modparam( "app_perl", "filename", "/opt/myprogram/perllib/MyKamailio.pm" ) ``` - In file `/opt/myprogram/perllib/MyKamailio.pm`: ```perl use Crypt::JWT qw( decode_jwt encode_jwt ); ``` - It happens that `Crypt::JWT` depends on `CryptX`, which in turn needs a `JSON::XS` implementation, which could be either `Cpanel::JSON::XS` or `JSON::XS`or `JSON::PP`, in that order of preference. That need is resolved at runtime, as we can see in the following code fragment taken from the file at https://github.com/DCIT/perl-CryptX/blob/master/lib/CryptX.pm: ```perl BEGIN { if (eval { require Cpanel::JSON::XS }) { Cpanel::JSON::XS->import(qw(encode_json decode_json)); $has_json = 1; } elsif (eval { require JSON::XS }) { JSON::XS->import(qw(encode_json decode_json)); $has_json = 2; } elsif (eval { require JSON::PP }) { JSON::PP->import(qw(encode_json decode_json)); $has_json = 3; } else { $has_json = 0; } } ``` - In my system, `Cpanel::JSON::XS` is not installed because it is not needed. I could install it, but unfortunately that module intermittently causes a segmentation fault, as described in the issue report at https://github.com/rurban/Cpanel-JSON-XS/issues/179. ### Expected behavior I would expect two things: - The operating system log files, like `/var/log/syslog`, adds only entries like the following ones after restarting Kamailio: May 25 14:30:06 myserver systemd[1]: kamailio.service: Succeeded. May 25 14:30:06 myserver systemd[1]: Stopped Kamailio server. May 25 14:30:06 myserver systemd[1]: Starting Kamailio server... May 25 14:30:06 myserver systemd[1]: Started Kamailio server. - The output of commands like `systemctl status kamailio.service` only shows informational messages of success. ### Actual observed behavior - The operating system log files, like `/var/log/syslog`, also adds error messages like the following one after restarting Kamailio: May 25 14:30:06 myserver /sbin/kamailio[1827476]: ERROR: app_perl [kamailioxs.xs:1041]: XS_Kamailio__Message_log(): perl error: Can't locate Cpanel/JSON/XS.pm in @INC (you may need to install the Cpanel::JSON::XS module) (@INC contains: /opt/myprogram/perllib /etc/perl /usr/local/lib/x86_64-linux-gnu/perl/5.30.0 /usr/local/share/perl/5.30.0 /usr/lib/x86_64-linux-gnu/perl5/5.30 /usr/share/perl5 /usr/lib/x86_64-linux-gnu/perl/5.30 /usr/share/perl/5.30 /usr/local/lib/site_perl) at /usr/local/lib/x86_64-linux-gnu/perl/5.30.0/CryptX.pm line 14. - The output of commands like `systemctl status kamailio.service` adds that same error message at its end. ### What could be changed in Kamailio? The `kamailio/src/modules/app_perl/lib/perl/Kamailio.pm` file could ignore, or bypass, the `__DIE__` signals coming from `eval` blocks, like this changed code fragment shows: ```perl $SIG{'__DIE__'} = sub { die @_ if( $^S or not defined $^S ); Kamailio::Message::log(undef, L_ERR, "perl error: $_[0]\n"); }; ``` That changed is based on the following references: - The [Override die with END or CORE::GLOBAL::die](https://www.effectiveperlprogramming.com/2011/05/overrid… article, which says: > There’s a Perl special variable that can help. The documentation for die recommends that you start your `__DIE__` handler by checking `$^S` before you continue. Inside the handler, the special handler is turned off so `die` inside `$SIG{__DIE__}` is the real `die`. The value of `$^S` will be true if it came from within an `eval`, so this just re-throws the exception without handling it. - The [Perl documentation for the `$^S` variable](https://perldoc.perl.org/perlvar#%24%5ES), which says: > Current state of the interpreter. $^S State --------- ------------------------------------- undef Parsing module, eval, or main program true (1) Executing an eval false (0) Otherwise > The first state may happen in `$SIG{__DIE__}` and `$SIG{__WARN__}` handlers. - The [Perl documentation for the `die` function](https://perldoc.perl.org/functions/die), which says: > You can arrange for a callback to be run just before the `die` does its deed, by setting the `$SIG{__DIE__}` hook. The associated handler is called with the exception as an argument, and can change the exception, if it sees fit, by calling `die` again. See `"%SIG"` in perlvar for details on setting `%SIG` entries, and `eval` for some examples. Although this feature was to be run only right before your program was to exit, this is not currently so: the `$SIG{__DIE__}` hook is currently called even inside `eval`ed blocks/strings! If one wants the hook to do nothing in such situations, put ```perl die @_ if $^S; ``` > as the first line of the handler (see "`$^S`" in perlvar). Because this promotes strange action at a distance, this counterintuitive behavior may be fixed in a future release. ### Additional Information * **Kamailio Version** - output of `kamailio -v` ```bash root@myserver:~# kamailio -V version: kamailio 5.4.3 (x86_64/linux) e19ae3 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_BLACKLIST, 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: e19ae3 compiled on 17:51:35 Feb 14 2021 with gcc 9.3.0 ``` * **Operating System**: ```bash root@myserver:~# uname -a Linux myserver 5.4.0-54-generic #60-Ubuntu SMP Fri Nov 6 10:37:59 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux ``` ```bash root@myserver:~# cat /etc/os-release NAME="Ubuntu" VERSION="20.04.1 LTS (Focal Fossa)" ID=ubuntu ID_LIKE=debian PRETTY_NAME="Ubuntu 20.04.1 LTS" VERSION_ID="20.04" HOME_URL="https://www.ubuntu.com/" SUPPORT_URL="https://help.ubuntu.com/" BUG_REPORT_URL="https://bugs.launchpad.net/ubuntu/" PRIVACY_POLICY_URL="https://www.ubuntu.com/legal/terms-and-policies/privacy-policy" VERSION_CODENAME=focal UBUNTU_CODENAME=focal ``` * **Perl version**: ```bash root@myserver:~# perl -V Summary of my perl5 (revision 5 version 30 subversion 0) configuration: Platform: osname=linux osvers=4.19.0 archname=x86_64-linux-gnu-thread-multi uname='linux localhost 4.19.0 #1 smp debian 4.19.0 x86_64 gnulinux ' config_args='-Dmksymlinks -Dusethreads -Duselargefiles -Dcc=x86_64-linux-gnu-gcc -Dcpp=x86_64-linux-gnu-cpp -Dld=x86_64-linux-gnu-gcc -Dccflags=-DDEBIAN -Wdate-time -D_FORTIFY_SOURCE=2 -g -O2 -fdebug-prefix-map=/build/perl-Wfb2Cd/perl-5.30.0=. -fstack-protector-strong -Wformat -Werror=format-security -Dldflags= -Wl,-Bsymbolic-functions -Wl,-z,relro -Dlddlflags=-shared -Wl,-Bsymbolic-functions -Wl,-z,relro -Dcccdlflags=-fPIC -Darchname=x86_64-linux-gnu -Dprefix=/usr -Dprivlib=/usr/share/perl/5.30 -Darchlib=/usr/lib/x86_64-linux-gnu/perl/5.30 -Dvendorprefix=/usr -Dvendorlib=/usr/share/perl5 -Dvendorarch=/usr/lib/x86_64-linux-gnu/perl5/5.30 -Dsiteprefix=/usr/local -Dsitelib=/usr/local/share/perl/5.30.0 -Dsitearch=/usr/local/lib/x86_64-linux-gnu/perl/5.30.0 -Dman1dir=/usr/share/man/man1 -Dman3dir=/usr/share/man/man3 -Dsiteman1dir=/usr/local/man/man1 -Dsiteman3dir=/usr/local/man/man3 -Duse64bitint -Dman1ext=1 -Dman3ext=3perl -Dpager=/usr/bin/sensible-pager -Uafs -Ud_csh -Ud_ualarm -Uusesfio -Uusenm -Ui_libutil -Ui_xlocale -Uversiononly -DDEBUGGING=-g -Doptimize=-O2 -dEs -Duseshrplib -Dlibperl=libperl.so.5.30.0' hint=recommended useposix=true d_sigaction=define useithreads=define usemultiplicity=define use64bitint=define use64bitall=define uselongdouble=undef usemymalloc=n default_inc_excludes_dot=define bincompat5005=undef Compiler: cc='x86_64-linux-gnu-gcc' ccflags ='-D_REENTRANT -D_GNU_SOURCE -DDEBIAN -fwrapv -fno-strict-aliasing -pipe -I/usr/local/include -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64' optimize='-O2 -g' cppflags='-D_REENTRANT -D_GNU_SOURCE -DDEBIAN -fwrapv -fno-strict-aliasing -pipe -I/usr/local/include' ccversion='' gccversion='9.3.0' gccosandvers='' intsize=4 longsize=8 ptrsize=8 doublesize=8 byteorder=12345678 doublekind=3 d_longlong=define longlongsize=8 d_longdbl=define longdblsize=16 longdblkind=3 ivtype='long' ivsize=8 nvtype='double' nvsize=8 Off_t='off_t' lseeksize=8 alignbytes=8 prototype=define Linker and Libraries: ld='x86_64-linux-gnu-gcc' ldflags =' -fstack-protector-strong -L/usr/local/lib' libpth=/usr/local/lib /usr/include/x86_64-linux-gnu /usr/lib /lib/x86_64-linux-gnu /lib/../lib /usr/lib/x86_64-linux-gnu /usr/lib/../lib /lib libs=-lgdbm -lgdbm_compat -ldb -ldl -lm -lpthread -lc -lcrypt perllibs=-ldl -lm -lpthread -lc -lcrypt libc=libc-2.31.so so=so useshrplib=true libperl=libperl.so.5.30 gnulibc_version='2.31' Dynamic Linking: dlsrc=dl_dlopen.xs dlext=so d_dlsymun=undef ccdlflags='-Wl,-E' cccdlflags='-fPIC' lddlflags='-shared -L/usr/local/lib -fstack-protector-strong' Characteristics of this binary (from libperl): Compile-time options: HAS_TIMES MULTIPLICITY PERLIO_LAYERS PERL_COPY_ON_WRITE PERL_DONT_CREATE_GVSV PERL_IMPLICIT_CONTEXT PERL_MALLOC_WRAP PERL_OP_PARENT PERL_PRESERVE_IVUV USE_64_BIT_ALL USE_64_BIT_INT USE_ITHREADS USE_LARGE_FILES USE_LOCALE USE_LOCALE_COLLATE USE_LOCALE_CTYPE USE_LOCALE_NUMERIC USE_LOCALE_TIME USE_PERLIO USE_PERL_ATOF USE_REENTRANT_API USE_THREAD_SAFE_LOCALE Locally applied patches: DEBPKG:debian/cpan_definstalldirs - Provide a sensible INSTALLDIRS default for modules installed from CPAN.
