Bananymous 391fc0c4c2 Kernel: Don't crash if Ext2 filesystem doing too many fileops 
I had a hardlimit of 10 block buffers and if they ran out, the kernel
would crash. this patchs increases the number of buffers to 16 and
removes the crash condition when they run out :D

Bananymous aaa8760d09 Kernel: Don't wait for ps2 timeout when flushing buffer 
This speeds up boot time by a second :dd:

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

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 :)
 2025-08-25 18:29:14 +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 9a6eae69ba Kernel: Replace all occurances of BSB with BSP 2025-08-25 17:11:32 +03:00
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)
 2025-08-21 03:11:16 +03:00
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 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 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!

Some syscalls were unconditionally validating optional paramenters which

Bananymous 809d07546a Kernel: Remove minimum timeout of 100 ms from epoll 
This is not actually needed and was just temporary code to make sure i
notified the epoll everywhere
 2025-08-15 18:28:11 +03:00
Bananymous 804cbeb1a7 Kernel: Increment kmalloc storage size to 64 MiB 
I really don't want to do this, but rewriting kmalloc to be dynamic
would require me to rewrite 32 bit paging and I really don't want to.

Bananymous c07188a60e Kernel: Look for PS/2 devices in the ACPI namespace
