Re: cannot get core dump of crashing freeradius

So after some debugging I got to the root cause of this: The process's dumpable flag is reset every time the UID is changed. FR does this several times with fr_suid_up() and fr_suid_down() after switch_users() is run, e.g. in listen_bind(). So I guess we have to change the fr_suid_* functions to always set the dumpable flag after setting the uid.

Ah... OK. That can be fixed for 2.1.9.

btw, I wonder why is prctl() is not called when debug_flag is set. I would have thought that one would want to get a core dump especially when running in debug mode.

It doesn't switch UIDs when in debug mode. So it inherits whatever code dump policy you set in the shell. Alan DeKok.
