Upgrade to 5.6.4 => [core/mem/q_malloc.c:519]: qm_free(): BUG: freeing already freed pointer
Hi team
I upgraded our lab to 5.6.4 from the official repository for ubuntu Jammy.
Now I get crashes related to TLS:
May 5 14:58:40 dev-cpereg01 kamailio[36147]: CRITICAL: <core> [core/mem/q_malloc.c:519]: qm_free(): BUG: freeing already freed pointer (0x7f4fedbed4e8), called from tls: tls_init.c: ser_free(323), first free tls: tls_init.c: ser_f ree(323) - ignoring May 5 14:58:40 dev-cpereg01 kamailio[36147]: CRITICAL: <core> [core/mem/q_malloc.c:519]: qm_free(): BUG: freeing already freed pointer (0x7f4fedd72b88), called from tls: tls_init.c: ser_free(323), first free tls: tls_init.c: ser_f ree(323) - ignoring May 5 14:58:40 dev-cpereg01 kamailio[36177]: CRITICAL: <core> [core/mem/q_malloc.c:519]: qm_free(): BUG: freeing already freed pointer (0x7f4fedd9e4a0), called from tls: tls_init.c: ser_free(323), first free tls: tls_init.c: ser_f ree(323) - ignoring May 5 14:58:40 dev-cpereg01 kamailio[36157]: CRITICAL: <core> [core/mem/q_malloc.c:519]: qm_free(): BUG: freeing already freed pointer (0x7f4fedd9e428), called from tls: tls_init.c: ser_free(323), first free tls: tls_init.c: ser_f ree(323) - ignoring
And a bit later on:
May 5 14:58:46 dev-cpereg01 kamailio[36179]: CRITICAL: <core> [core/pass_fd.c:277]: receive_fd(): EOF on 34 May 5 14:58:46 dev-cpereg01 kamailio[36143]: ALERT: <core> [main.c:774]: handle_sigs(): child process 36161 exited by a signal 11 May 5 14:58:46 dev-cpereg01 kamailio[36143]: ALERT: <core> [main.c:777]: handle_sigs(): core was generated May 5 14:58:46 dev-cpereg01 kamailio[36143]: INFO: <core> [main.c:799]: handle_sigs(): terminating due to SIGCHLD
Has there been a fundamental change in TLS? Or did I miss something important to do on a 5.5 => 5.6 upgrade?
Hello,
in case Kamailio is linked with OpenSSL 3.0 it will fail. Linking with Openssl 1.1.1 works.

Hi Дилян
in case Kamailio is linked with OpenSSL 3.0 it will fail. Linking with Openssl 1.1.1 works.
Version: 5.6.4+ubuntu22.04 Architecture: amd64 Maintainer: Kamailio Admin Group kadmin.hq@lists.kamailio.org Installed-Size: 1072 Depends: kamailio (= 5.6.4+ubuntu22.04), libc6 (>= 2.34), libcurl4 (>= 7.16.2), libssl3 (>= 3.0.0~~alpha1)
# ldd /usr/lib/x86_64-linux-gnu/kamailio/modules/tls.so linux-vdso.so.1 (0x00007ffdf0517000) libssl.so.3 => /lib/x86_64-linux-gnu/libssl.so.3 (0x00007fbc5f86f000) libcrypto.so.3 => /lib/x86_64-linux-gnu/libcrypto.so.3 (0x00007fbc5f42c000)
So am I guessing right, that the Ubuntu Jammy package from kamailio.org is linked against OpenSSL 3.0.0 causing those crashes?

indeed, support for openssl 3.0 is not fully tested and while it compiles with some warnings, there were reports of issues with it.
But I wanted to check if you started with --atexit=no cli param, because your error messages seemed linked to start up time.
Cheers, Daniel
Hi Daniel

Yes, --atexit=no parameter is set in the systemd file. Shall I try without?

Hello!
It was mentioned in this issue: https://github.com/kamailio/kamailio/issues/3222#issuecomment-1222104843
Seems no significant changes till than. (I'm also using tlsa with 1.1.1 version)
