Bananymous 2ea0a24795 Kernel: Fix TCP SYN option propagation 
Listening socket now forwards TCP options to the newly created socket
 2026-02-23 23:00:47 +02:00
Bananymous acf28d8170 Kernel: Use ring buffers for TCP windows 
This speeds up TCP networkign a ton as it doesnt have to do unnecessary
memmoves for each send/receive
 2026-02-23 21:10:13 +02:00
Bananymous 666a7bb826 Kernel: Rework TCP window size reporting 
We now report actually available window size when sending packets. If
the available window size grows significantly we send an ACK to reflect
this to the remote.

EPOLLOUT is now sent to the correct socket and buffer is now a ring
buffer to avoid unnecessary memmove on every packet

Bananymous 8fb2270ecf DynamicLoader: map RO sections actually read only 
I was mapping everything RW as i did not have mprotect when I
implemented the dynamic loader.

Bananymous c304133224 LibC: Indicate regex support in unistd.h 2026-01-25 01:47:30 +02:00
Bananymous 7843d3de62 LibC: Support attrs and file actions in posix spawn 
Apparently GCC wants to use posix_spawn now that it is available, this
patch adds support for the missing fields. POSIX Issue 8 did add some
fields that are not supported here

Bananymous ba6229b92d Kernel: Fix TCP accept bind address 
I was accidentally binding the new socket to the target address instead
of the listening socket's address
 2026-01-24 00:33:05 +02:00
Bananymous 3d2362cb5f ports/xash3d-fwgs: Don't apply vorbis patch 
I removed the pathes a while ago
 2026-01-21 19:20:02 +02:00
Bananymous a08b9b82a6 Kernel: Fix yield stack pointer value 
Stack pointer was pointing to value of return address on return instead
of past it. This did not affect anything as ig Processor::yield() didn't
use stack after calling the trampoline
 2026-01-19 00:47:00 +02:00
Bananymous 5d62fa3f10 Kernel: Clenup stacktrace printing on exception 
Start from current ip and bp. This removes kernel call stack to debug
printing function from the stack trace
 2026-01-16 16:31:35 +02:00
Bananymous d3df00f0ba Kernel: Make Processor structure default to zero 
This moves processor info to bss instead of having it in data section
 2026-01-16 16:24:47 +02:00
Bananymous 34e84f8b07 Kernel: Reduce the number of TLB invalidations 
Invalidations are not done if mapping or unmapping previously unmapped
page. TLB invalidate IPIs are now ignored if they don't affect the
currently mapped address space
 2026-01-16 16:22:29 +02:00
Bananymous 1143dc3cae Kernel: Rework syscall memory validation and locking 
Process's memory regions are now behind an rwlock instead of using the
full process lock. This allows most pointer validations to not block as
write operations to memory regions are rare.

Thread's userspace stack is now part of process's memory regions. This
simplifies code that explicitly looped over threads to see if the
accessed address was inside a thread's stack.

Only drawback of this is that MemoryRegions don't support guard pages,
so userspace stackoverflow will be handeled as cleanly as it was prior
to this.

This patch also fixes some unnecessary locking of the process lock and
moves locking to the internal helper functions instead of asserting that
the lock is held. Also we now make sure loaded ELF regions are in sorted
order as we previously expected.

Bananymous 0299d4d44e Kernel/LibC: remove SYS_TERMID 
This syscall is not needed. /dev/tty is already a symlink to the
controlling terminal. Also this syscall did not handle pseudo terminals
 2026-01-16 15:57:36 +02:00
Bananymous 1d07151743 ports/xash-fwgs: Cleanup patches 
Remove patches that are no longer needed and cleanup the general support
patch

Bananymous a83fa6f4c6 Kernel: Optimize futexes 
Eeach futex object now has its own mutex to prevent unnecessary locking
of the process/global futex lock. This basically removes sys_futex from
profiles when running software with llvmpipe
 2026-01-13 19:18:52 +02:00
Bananymous c30fc9d60f LibGUI: Rewrite using epoll 
select is slow :^)
 2026-01-12 23:53:11 +02:00
Bananymous 311a68160c Kernel: Don't delete futex objects after they are not used anymore 
Hashmap insertions and deletions made futex very slow to use. When
running SuperTuxKart, ~15% of cpu time was spent doing these.

Never freeing objects is not great either but at least the performance
is usable now :)

Bananymous 343aef31c3 AudioServer: Rewrite using epoll 
select is slow :^)
 2026-01-12 23:46:51 +02:00
Bananymous 3ac8f7e14f WindowServer: Rewrite using epoll 
Looking at profiles, select is a very slow syscall as it has to allocate
a temporary epoll instance

Bananymous c9a8f5b456 Kernel: Fix ext2 fileystem super block backups 
Check if rev >= 1 sets sparse superblock feature instead of assuming it
is set
