libcrash Building ~~~~~~~~ # make or # CROSS_COMPILE=/path/to/toolchain/toolchain_refix- make Testing ~~~~~~~ Two tests and one utility program for testing are provided. test: normal applciation test (application calls registration function). auto_test: automagic usage test (library loads magically with unaltered program) To run the tests - for normal usage: # ./test for automagicall usage: # ldconfig -n . # LD_PRELOAD=libauto_crash.so.1 ./auto_test Usage ~~~~~ Have your program link with libcrash.so.1 and call register_crash_handler() once for each process (not thread): int register_crash_handler( const char * process_name, /* Name of Process, such as argv[0] */ unsigned char * assert_buf_ptr /* Pointer to program assert buffer */ ); Re-call after fork(). The registrtation functrion return 0 if all is well, and a negative number with the value of the errno function that cause it to fail otherwise. See test.c for usage example. Normally running the program should then use the library and we'll send crash info to tdout Alternatibly, you can use # LD_PRELOAD=libauto_crash.so.1 ./program To run the library with an unchanged (but non SUID) binary program with no source alterations.
