apio	5f698b4774	kernel: Don't create a new kernel stack on exec() ... The old one was not getting freed, creating a memory leak every exec(), which can get huge over time. Plus, there was no need for a new stack. And we couldn't just free the old one, since sys_execve() runs on the old stack...	2023-07-12 16:06:56 +02:00
apio	f629e17ff4	kernel/x86_64: Only show kernel addresses in backtraces ... This avoids walking off into userspace memory where we don't know what could happen.	2023-07-12 16:04:45 +02:00

apio	d27ffce5db	kernel: Move the signal handling logic to after a syscall sets its return value ... When a signal was caught after a syscall, it was doing so without preserving the return value of the syscall.	2023-07-12 13:34:30 +02:00
