apio	6bdf3169d2	kernel: Handle aborted connections instead of crashing	2024-02-03 19:15:19 +01:00
apio	fd402083d7	kernel: Fix kernel panic when adding a timer before another one ... This was caused because add_to_timer_queue() did not set active_clock when inserting a timer before the end, making disarm() a no-op. Therefore, the clock would continue to use the timer after it had been freed.	2024-01-06 18:12:25 +01:00
apio	4019cf90cf	kernel: Unify panic messages	2024-01-06 17:44:56 +01:00
apio	17b44a8ce6	kernel: Reenable stack tracing in kernel-mode exceptions ... Stack tracing in user-mode exceptions was moved to when a signal kills the process, but this isn't done for kernel-mode exceptions so there was no stack trace anymore.	2024-01-05 22:14:31 +01:00
