I have a daemon process I've written and trying to debug, however, whenever it crashes, I get no core file.
1. The daemon does a setrlimit of RLIMIT_CORE to RLIM_INFINITY (same as if I had done "ulimit -H -c unlimited" in the shell before starting the process). 2. The daemon sets its working directory to /var/tmp, which is writeable by every one, yet no core file appears. Likewise /var/crash has no core file. 3. The program does not use file system setuid bits, BUT does use the setuid() et al. system calls to drop privileges from root to some other user (which can write into /var/tmp). 4. A find / -name '*.core' finds nothing anywhere. 5. I've even tried sysctl kern.nosuidcoredump=0 and kern.nosuidcoredump=2 thinking that the setuid family of system functions might be resetting a flag when I drop privileges. 6. Even forcing a SIGABRT, which should produce a core, does not create one. What am I missing in order to get a daemon process on OpenBSD to dump core when it crashes? -- Anthony C Howe Skype: SirWumpus SnertSoft +33 6 11 89 73 78 Twitter: SirWumpus BarricadeMX & Milters http://snert.com/ http://nanozen.info/ http://snertsoft.com/
