Hi Heylen,
I has asked you long time ago question regarding core_dump in openwrt.
It used to work but now it is not generating any core deump.I am following the
following from the past:
I would like to enable core-dump functionality on my openwrt machine. I am
using latest atitude adjustmnet.I enabled busybox->init->support dumping code
for child processI also enabled in kerneln_menuconfig
GeneralSetup->configure standard kernel->Enable ELF core dump.I also set up
/proc/sys/fs/suid_dumpable /proc/sys/kernel/core_uses_pid
But I can't see any core dump created .I appreciate if someone can give some
hints.
also I have setup the following from your E-mail:
touch /.init_enable_core
sysctl -w "kernel.core_pattern=/tmp/%e.%p.%s.%t.core"
But I am not seeing any coredump when I see a segfault or kill a process kill
-11 <pid>.
I would appreciate your help again,BR,farid

Hi Farid,
on your target you should extra do the following:
touch /.init_enable_core
sysctl -w "kernel.core_pattern=/tmp/%e.%p.%s.%t.core"
the first will enable core dumps on all applications started with busybox init
(so the feature you enabled)
the second will tell the kernel where to store the core dumps (e.g. in /tmp/)
