Next Monday, 30th of June, at 18:30 the Haifa Linux Club, will gather
to hear Gilad Ben-Yossef's lecture about
Crash and burn: writing Linux application fault handler
Complementing the standard Linux fault handler ("Segmentation fault.
Core dumped.") with a custom handler that reports the crashing program
state without a debugger is a useful endeavor in many situations.
Unfortunately, writing such a fault handler correctly can be
surprisingly hard and requires certain amount of black magic.
The proposed lecture is a tutorial that will demonstrate how to write
such a handler, covering such topics as: getting program symbolic stack
trace and registers and reporting them safely, the care and feeding of
async signal POSIX handler functions, how to avoid implicit memory
allocations and how to test for them, how to handle multi-threaded
faults, the black magic involved with how Linux handles signal handlers,
the unfortunate effect this has on obtaining a correct stack trace in
case of a fault and how to overcome this limitation.
We meet in Taub building, room 6. For instructions see:
