Bananymous 8ea0a67280 Terminal: Add support for tabs 2025-06-06 16:41:06 +03:00
Bananymous 5ad7d7edb1 DynamicLoader: Fix TLS on 32 bit platform 
There were two problems with my previous implementation
- TLS was not allocated if nothing used it. There is a fallback
  initialization in _init_libc, but this was not enough if one of the
  init functions tried to access errno.
- __tls_get_addr was not resolved. If __tls_get_addr was called through
  a plt entry, everything would just break :(

Bananymous 00c6820825 LibC: Make {open,sys,close}log use their own FILE instead of stddbg 2025-06-06 11:59:15 +03:00
Bananymous 6beaafcf11 LibC: Define std{in,out,err,dbg} with their actual names 2025-06-06 11:56:39 +03:00
Bananymous e92f039a17 Kernel: Fix tcp sending with already sent unacknowledged bytes 2025-06-06 11:55:44 +03:00
Bananymous ef76ffa1c1 Kernel: Remove unnecessary hack 
This is no longer needed as thread unlocks its spinlock before calling
Process::exit() on terminating signal
 2025-06-06 11:13:55 +03:00
Bananymous 652eb2346c Kernel: Fix syscall interrupt disabling 
If thread had a terminating signal, syscall leaving would try to lock
process's mutex while not having interrupts enabled
 2025-06-06 11:12:48 +03:00
Bananymous 66726090ec Kenrel: Fix TCP connection closing 
If TCP socket was connected with connect() instead of accept() it would
never send FIN to other end when it was closed.

Bananymous b668173cba Kernel: Fix pseudo terminal writability 2025-06-06 11:09:50 +03:00

Bananymous c6ded82406 Kernel: Fix a deadlock when thread is executing terminating signal 2025-06-06 06:52:27 +03:00
Bananymous a76c6faffc Kernel: Fix a deadlock when process is exiting 2025-06-06 06:52:02 +03:00
Bananymous 81ff71a97f Kernel: Track the number of recursive spinlocks a thread is holding 2025-06-06 06:51:15 +03:00
Bananymous 56db0efe58 Kernel: Add missing file for race condition fixes :) 2025-06-06 04:03:37 +03:00
Bananymous 5eefd98e1b Kernel: Add debugging macro to dump syscalls that take a long time 2025-06-06 04:00:57 +03:00
Bananymous eecdad50a6 Kernel: Fix most of mutex + block race conditions 
All block functions now take an optional mutex parameter that is
atomically unlocked instead of having the user unlock it before hand.
This prevents a ton of race conditions everywhere in the code!

Bananymous 96d5ed9cc7 Kernel: Fix E1000 driver interrupts 
I have no idea why, but E1000 seems to be missing interrupts frequently
when clearing ICR only at the end of the interrupt handler
 2025-06-06 03:45:35 +03:00
Bananymous 73090ecb37 Kernel: TTY set EPOLLOUT 2025-06-05 22:04:51 +03:00
Bananymous 8812704601 Kernel: Make sure IPv4 and ARP packets are not missed 
This is a really hacky solution but will do until i get atomic
unblocking with respect to locks
 2025-06-05 22:03:15 +03:00
Bananymous 0f189d410e Kernel: Fix unix socket recv from 
If connection on unix socket was closed and other end tries to recvfrom,
the thread would enter a fucked up state where it held the socket's
spinlock when returning to userspace.

Bananymous cfeabc4580 Kernel/Terminal: Fix ANSI SGR 8 bit color parsing 2025-06-05 20:43:57 +03:00
Bananymous 49f203d61d Terminal: Add ANSI CSI P and ANSI SGR 22 2025-06-05 02:41:48 +03:00
Bananymous a912a4dc67 LibGUI: Remove fill_color from texture copy API 
Nothing was using this and it just overcomplicated everything
 2025-06-05 02:40:51 +03:00
Bananymous f79db874bf Kernel: Fix ANSI CSI 1J 
I was accidentally clearing the whole screen when I needed to clear from
cursor to the end of the screen
 2025-06-05 02:38:57 +03:00
Bananymous 8de19aff3c Kernel/Terminal: Fix 24 bit ANSI SGR color parsing 2025-06-05 02:38:07 +03:00
Bananymous bf41b448d6 Kernel: Fix TCP sending 
- Fix race condition when adding packet to send buffer before other end
  has acknowledged it
- Allow sending multiple packets before receiving ACK for previous ones
 2025-06-04 22:21:35 +03:00
Bananymous 448632cf11 Kernel: Add fast path to pselect and ppoll 
If events are available right away, don't create epoll object to wait
on. Also fix pselect return value to the number of bits set. Previously
return value could've been greater than that if epoll return EPOLLERR or
EPOLLHUP for events that were not listened to

Bananymous 11174bfa14 BuildSystem: Rename toolchain -> x86_64-pc-banan_os 2025-06-03 23:02:10 +03:00
Bananymous 84b1f3990c LibC: Fix getnameinfo 
How was i doing everything so wrong :D

Bananymous 943069b2a3 Kernel: Socket EPIPE and send SIGPIPE on write after hang up 2025-06-03 10:24:44 +03:00
Bananymous e305698e6b Kernel: Fix epoll EPOLLHUP and EPOLLERR reporting 2025-06-03 10:23:53 +03:00
Bananymous 4c0b7d44b4 Kernel: Enable ECHOE and ECHOK, support VKILL, fix VEOF 2025-06-02 16:26:53 +03:00
Bananymous 775c77c0fa Shell: Get default backspace key from c_cc[VERASE] 2025-06-02 15:55:20 +03:00
Bananymous fb466b5af7 Kernel: use termios c_cc values instead of hardcoded characters 2025-06-02 15:54:11 +03:00
Bananymous e473118ec8 userspace: Add nologin "shell" 2025-06-02 12:26:16 +03:00
Bananymous 755d41ca4e LibC: Add pw_passwd and pw_gecos to passwd structure 
This information is available in /etc/passwd either way so why not
expose it to the user. Practically all UNIX-likes have these either way
 2025-06-02 12:23:06 +03:00
Bananymous bbff9f89b0 BuildSystem: Don't invoke ninja directly, but use cmake --build 2025-06-02 11:45:06 +03:00
Bananymous fdcb38ac1f Shell: Accept '\r' as enter 
This happens with some terminals and i don't want to bother with fixing
my termios :D

Bananymous fac742c038 test-sort: Add qsort test 2025-06-02 11:41:34 +03:00
Bananymous 5a6b43fc90 LibC: Remove debug printing from getnameinfo 2025-06-02 11:39:18 +03:00
Bananymous 317f413746 LibC: Implement very hacky posix_memalign 
I did not even test this and i know the code is super hacky. I could not
bother with writing proper code for this xD
 2025-06-02 11:39:18 +03:00
Bananymous 895909b7fa LibC: Add CMSG_* definitions to sys/socket.h 2025-06-02 11:39:18 +03:00
Bananymous 2ee8b6c8b4 LibC: Add more definitions to netinet/in.h 
These are non-standard but a lot of UNIX-likes have them networking
software attempts to use them
 2025-06-02 11:39:18 +03:00
Bananymous 022bb69782 LibC: Implement inet_aton 
This is not POSIX but IMO it makes sense to have the counter part to
inet_ntoa

Bananymous be6da3e0db BuildSystem: Compile gcc with threading support 2025-06-02 11:39:18 +03:00
Bananymous 1f07e02298 BuildSystem: Fix cmake toolchain file processor 2025-06-02 11:39:18 +03:00
Bananymous 7a645b8555 Kernel: Add SMP message StackTrace 
This event is sent when user presses ctrl+{F1-F12} and it will dump the
corresponding processor's stack trace. This is really helpful for
detecting deadlocks in the system
 2025-06-02 11:39:18 +03:00
Bananymous c5b0d0235f Kenrel: Allow Processor::send_smp_message to send event to current CPU 2025-06-02 11:39:18 +03:00
Bananymous b7948551ff userspace: Add empty libm and libpthread 
These making porting stuff easier. I could not find a way to tell CMake
that the system does not have threads library
 2025-06-02 11:39:18 +03:00
Bananymous e109b5cff6 Kernel: Remove unnecessary locks from Pipe 
Inode already locks its own mutex when read/write is called there is no
need to explicitly lock them in read_impl/write_impl
