[kamailio/kamailio] ndb_redis: fix SIGSEGV in redisc_check_auth (#2834)
by Dennis 26 Aug '21

26 Aug '21

Hi ! This issue appears when ndb_redis module connect to redis via proxy, in my case haproxy. Haproxy keeps front socket always open, when all backend redis servers become unavailable, haproxy just send RST to front, redisCommand function in tis case return NULL poiner, redisc_check_auth try to dereference it without NULL checking. kamailio log: `kernel: [7250430.508827] kamailio[21749]: segfault at 0 ip 00007f00d7bb106f sp 00007fffc523c620 error 4 in ndb_redis.so[7f00d7b94000+36000]` gdb: ``` # gdb /usr/sbin/kamailio core GNU gdb (Ubuntu 8.1.1-0ubuntu1) 8.1.1 Copyright (C) 2018 Free Software Foundation, Inc.

Troubleshooting segfault in shared memory
by Anthony Alba 26 Aug '21

26 Aug '21

Hi sr-dev, I have a pointer from one child process A that is available to another child process B (this is a custom module I am developing). The object should have been allocated in shared memory by A using ser_malloc and friends and thus accessible from B. However B is encountering a segfault when accessing this object. Given a pointer how can I tell whether the memory it is pointing to is valid in all children, i.e, the target is in kamailio shared memory? Thanks Anthony Alba
