How to replace the default handler with user defined handler in Linux
File Function called
1.source/ arch/i386/kernel/signal.c -----> do_signal( )
2.source/kernel/signal.c ----------> get_signal_to_deliver( )
3.source/fs/exec.c -------------> do_coredump( )
4.source/fs/binfmt_elf.c -------------> elf_core_dump( )
Now,as per project requirements, i need to modify the default signal handler definitions with my own user defined signal handler that handles various exceptions (SIGSEGV, SIGFPE, SIGABRT etc) causing coredump. Further, i need to build the kernel for keeping the changes in kernel with my handler replacing default handler.
Can anybody please share the proceedings to do those operations ?
Advance thanks to all repliers
