I was using a wrong register for signal mask storage...

Bananymous cea19ecc31 Kernel: Fix possible crash during exec 2025-08-28 15:55:40 +03:00
Bananymous 706cfeb443 Kernel: Allow file backed mapping be larger than inode size 
This is only allowed if the mapping does **not** exceed a page boundary.
Some port was doing an exactly two-page-mapping on a file that was one
and a half page long

There isn't really any need to :D

Bananymous 10bd24e585 Kernel: Fix signal delivery without an alternate stack 
I had only tested that sigaltstack worked, so I didn't notice my normal
signals broke :D

Bananymous f926e599fa Kernel: Zero initialize Processors 
This moves processor array to .bss reducing data size by 8192 bytes :)

This needed GCC updated to 15.2.0 because of an internal compiler error
I found :)

Bananymous e7b518ba67 BuildSystem: binutils 2.44->2.45, gcc 15.1.0->15.2.0 2025-08-25 18:25:36 +03:00
Bananymous a4698f0bde Kernel: Fix IOAPIC max redirection entry fetching 
Also max redirection entry is an index, not count so comparisons should
check for equality :)

Bananymous 2f3fd6867d Kernel: Add VERY HACKY MAP_FIXED fix 
This definitely will break stuff but I don't think anything depends on
this (except maybe dynamic loader)

This WILL get fixed soon (I hope :D)

Bananymous 350ae90bb6 Kernel: Make all futexes shared 
Some stuff tries to use shared futexes so make them all shared. Private
futexes would be faster as they are process specific but supporting both
would need some reworks

Bananymous fb61cab70d LibC: Rewrite pthread_mutex using a futex 2025-08-21 02:52:49 +03:00
Bananymous 1d6c08478d LibC: Fix sigsetjmp 
the call from C sigsetjmp messed up rbp, now sigsetjmp is also written
in assembly.

I did not test the 32 bit code, just ported the tested 64 bit version
over :D

Bananymous 8b26b6604d LibC: Make mbstate_t into int 
This is not used, but makes more sense than an empty struct

Bananymous 34bdcb12e5 Kernel: Fix termios and enter key handling 
Enter key now produces expected \r which gets converted to \n by default
by the ICRNL input flag.

Also input flags are now handled always, not just when ICANON is set.
I don't know why I though ICANON should disable input handling

Bananymous 95b353dae5 LibInput: Fix numpad keycode generation 
I had made this function with broken PS/2 scancode set 3, so it seemed
like it worked

Bananymous 32d7f429f8 Kernel: Fix default ignored signals 
SIGWINCH and SIGCANCEL ended up interrupting functions even when they
were marked as SIG_DFL. Now resizing the userspace terminal emulator
does not get interrupted!
