[kamailio/kamailio] secfilter crash when using kamcmd secfilter.reload (Issue #3263)
by amoizard 20 Oct '22

20 Oct '22

### Description Hello! I'm running a sip service and have several crash per day. The crash is happening in secfilter module, method "w_check_ip" line 651 https://github.com/kamailio/kamailio/blob/master/src/modules/secfilter/secf… #### Reproduction I noticed that every core is generated when I insert a new IP and most probably, when I call kamcmd secfilter.reload NOTE: I'm calling the above command line from the kamailio script #### Debugging Data ``` (gdb) bt #0 __strncasecmp_l_avx () at ../sysdeps/x86_64/multiarch/strcmp-sse42.S:271 #1 0x0000564a161b6413 in cmpi_str (s1=0x7f0bdcbc1b28, s2=0x7ffd88e2c580) at core/strutils.c:443 #2 0x00007f0bd069c983 in w_check_ip (msg=0x7f0be1619620) at secfilter.c:651 #3 0x0000564a15f8cafc in do_action (h=0x7ffd88e2d640, a=0x7f0be142f118, msg=0x7f0be1619620) at core/action.c:1079 #4 0x0000564a15f9bb26 in run_actions (h=0x7ffd88e2d640, a=0x7f0be14296e8, msg=0x7f0be1619620) at core/action.c:1584 #5 0x0000564a15f889d9 in do_action (h=0x7ffd88e2d640, a=0x7f0be15996f0, msg=0x7f0be1619620) at core/action.c:703 #6 0x0000564a15f9bb26 in run_actions (h=0x7ffd88e2d640, a=0x7f0be1598c70, msg=0x7f0be1619620) at core/action.c:1584 #7 0x0000564a15f9c3a0 in run_top_route (a=0x7f0be1598c70, msg=0x7f0be1619620, c=0x0) at core/action.c:1669 #8 0x0000564a160f2e96 in receive_msg ( buf=0x564a16549ea0 <buf> "REGISTER sip:sip.antisip.com SIP/2.0\r\nVia: SIP/2.0/UDP 10.1.1.78:5060;branch=z9hG4bKVsAO82I6G4Oe4Okgc;rport\r\nFrom: \"504f9410db5c\" <sip:XXXXXXXXXXXX@sip.antisip.com>;tag=D2yOicg8WAMe4Sii\r\nTo: \"XXXXXXXX"..., len=429, rcv_info=0x7ffd88e2daf0) at core/receive.c:501 #9 0x0000564a16251d97 in udp_rcv_loop () at core/udp_server.c:543 #10 0x0000564a15f75ce9 in main_loop () at main.c:1730 #11 0x0000564a15f829a1 in main (argc=10, argv=0x7ffd88e2e508) at main.c:3061 ``` #### Log Messages Oct 12 00:28:08 sip kamailio[19274]: ALERT: <core> [main.c:788]: handle_sigs(): child process 19474 exited by a signal 11 Oct 12 00:28:08 sip kamailio[19274]: ALERT: <core> [main.c:791]: handle_sigs(): core was generated Oct 12 00:28:08 sip kamailio[19274]: INFO: <core> [main.c:813]: handle_sigs(): terminating due to SIGCHLD #### SIP Traffic not applicable ### Possible Solutions I guess the secfilter reload is happening at the same time w_check_ip loops over the data. Some mutex should probably be missing. ### Additional Information Debian GNU/Linux 11 (bullseye) kamailio 5.5.5 (x86_64/linux) installed from http://deb.kamailio.org/ secfilter module hasn't changed much since 5.5.5, so I it looks like master branch is still affected.

Testing dialog module (and acc with dialog cdrs)
by Daniel-Constantin Mierla 18 Oct '22

18 Oct '22

Hello, as I am not a user of dialog variables, I am turning to community to ask for help testing the current master branch with configurations that make use of dialog variables and acc dialog-based cdr generation. With a few reports of issues related to dialog modules and unexpected crashes, I looked over the code and noticed that the access of the value for dialog variables was not protected, making them vulnerable of invalid memory access in case of the variable was updated by another process or dialog was terminated. I introduced a couple of new functions to try to cover different use cases of getting the dlg variable values, dialog management code was not affected, but given that these commits need to be backported to stable branch (5.6), I want to get proper feedback from community that things work fine. A previous attempt of a simpler fix was not enough, having side effects to acc module for dialog-based cdr generation, because it was keeping referenced to many dlg variables at the same time. In short, it would be appreciated any feedback on testing dialog and acc with dialog-based cdr generation using git master branch.

This crash happen when "rpc_mod_is_printed_one" funtion recevies the parameter ( mem_counter *stats ) as NULL. To avoid the crash, we have added the below code. if ( stats == NULL || current == NULL ) { LM_ERR("rpc_mod_is_printed_one -> funtion parameter contains null value \n"); return 1; } You can view, comment on, or merge this pull request online at: https://github.com/kamailio/kamailio/pull/3250 -- Commit Summary -- * Update mod_stats.c Random crash in CTL handler -- File Changes -- M src/modules/kex/mod_stats.c (6) -- Patch Links -- https://github.com/kamailio/kamailio/pull/3250.patch https://github.com/kamailio/kamailio/pull/3250.diff -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/pull/3250 You are receiving this because you are subscribed to this thread.
