 2025-04-23 22:03:53 +03:00
Bananymous cc7c1ad30d Kernel: Add per terminal palette for TerminalDriver 
This allows better color approximation on text mode and in future will
allow user to possibly change the palette

 2025-04-23 08:09:51 +03:00
Bananymous 20e17a28cf Kernel: Fix \b handling 
Don't clear the character, only move cursor backwards

 2025-04-22 09:55:38 +03:00
Bananymous 96740d6be4 LibC: Make inet_addr spec compliant

 2025-04-22 09:40:46 +03:00
Bananymous b853d29992 Kernel: Fix unix domain socket close detection 2025-04-22 08:36:44 +03:00
Bananymous 33a0f562d3 resolver: Add support for CNAME

use getaddrinfo
 2025-04-22 08:36:44 +03:00
Bananymous f8e3ae0525 Kernel: Fix deadlock caused by multithreading 
This allows multiple threads to concurrently call the most common
blocking syscalls:
- read
- write
- accept
- connect
- sendto
- recv
- pselect

This prevents a dead lock when for example process is waiting on a pipe,
but unable to write to it since process is locked.

This is the beginning of starting to remove processes own lock from
syscall and locking only necessary parts.
 2025-04-22 04:51:53 +03:00
Bananymous c790bad667 Kernel: Make OpenFileDescriptorSet thread safe 
Also this allows concurrent calling of read/write/send/recv
 2025-04-22 04:31:18 +03:00
Bananymous d54489bbcb Kernel: Implement MemoryRegion pinning 
This allows process to pin a MemoryRegion into users memory space for
syscall duration without allowing user to munmap the region.
 2025-04-22 04:30:07 +03:00
Bananymous 808c97020a Kernel/LibC: Implement SA_RESTART 
I have been thinking how to do this for a long time but I finally
figured out a semi-clean way
 2025-04-22 02:42:44 +03:00
Bananymous 34e680d792 ports/ncurses: Set some needed environment variables 
ncurses depends on these being set to function properly
 2025-04-22 01:56:34 +03:00
Bananymous 32d543943b ports: Add lynx port 
I have had this for a while but apparently never commited :D
 2025-04-22 01:44:49 +03:00
Bananymous 2632507980 ports/ca-certificates: Add symlink to /etc/ssl/cert.pem

Bananymous 5c9710c78b LibC: Implement strcoll_l 2025-04-22 00:48:26 +03:00
Bananymous 107b31a0b5 Kernel: Fix E1000{,E} driver for older qemu versions 
This patch adds clearing of *Interrupt Cause Registers*, which allows
older qemu versions to send new interrupts. Apparently this is not
needed on newer releases.
 2025-04-22 00:31:13 +03:00
Bananymous 028c7a822f LibC: Don't define SCHAR_MAX in locale.c 2025-04-21 22:21:40 +03:00
Bananymous 18f5f98e62 General: Mark USB hubs done in README 2025-04-21 22:13:31 +03:00

Bananymous 5305f962c0 ports/openssl: Make openssl port threaded 2025-04-21 19:59:57 +03:00
Bananymous b774f147da LibC: Implement dummy pthread_attr_{get,set}detachstate 
detached threads are not yet supported, but this allows implementation
to make sure threads are joinable.
 2025-04-21 19:58:01 +03:00
Bananymous 2a5921b9c9 LibC: Implement pthread_barrier 
This is not fully working but should be fine for most cases
 2025-04-21 19:53:38 +03:00
Bananymous 60cb392e97 LibC: Implement pthread_barrier 
This is yet another bad sched_yield implementation :D
 2025-04-21 19:52:14 +03:00
Bananymous d012c538c3 LibC: Add PTHREAD_SPIN_INITIALIZER 
This is not posix, but current implementation allows adding this
 2025-04-21 19:47:00 +03:00
Bananymous 1c88d0d7f7 LibC: Implement pthread_rwlock 
This uses the same dumb sched_yield instead of actually blocking :D
 2025-04-21 18:48:47 +03:00
Bananymous 773b8de8ba LibC: Refactor pthread type definitions 2025-04-21 14:38:40 +03:00

Bananymous db9db2cc40 LibC: Implement basic pthread mutexes 
This implementation is just calling sched_yield if it could not get
mutex. This is not optimal as it does not allow the CPU to idle, but it
works for now :)

Also I did not test this code at all, but it feels correct :D
 2025-04-20 03:27:16 +03:00
Bananymous 3642eabac0 LibC: Use BAN::atomic_* functions in pthread spinlock 
This allows us not to reinterpret_cast pthread_spin_t to
BAN::Atomic<pthread_spin_t> which is much better :)
 2025-04-20 03:11:41 +03:00
Bananymous 98e05fd179 BAN: Implement atomic functions for normal integers 2025-04-20 03:11:41 +03:00

 2025-04-20 03:11:41 +03:00
Bananymous 85f9b585f5 LibC: Don't yield on pthread_spin_lock

depending on the current locale
 2025-04-19 20:02:01 +03:00

This allows potential blocking
 2025-04-19 00:39:42 +03:00
Bananymous 63b3d9875d Kernel: Fix Thread::block_with_eintr* functions 
I was using wrong block function, `block_with_timeout` instead of
`block_with_wake_time`. This caused functions to block way too long and
caused a lot of hangs.
 2025-04-19 00:39:42 +03:00
Bananymous 8cd2d772b0 Shell: Print error if execv fails 2025-04-19 00:39:42 +03:00
Bananymous 2ff3f88b4d LibC: Add support for shebangs 
I implemented shebangs in userspace as I don't really see the benefit of
doing it in kernel space. Only benefit I can think of is executing non
readable scripts but I don't really see the benefit in that.
 2025-04-19 00:39:42 +03:00

flags

indices.
 2025-04-18 04:17:31 +03:00
Bananymous 9258c73484 Kernel: Optimize VTTY cursor rendering

handled.

Bananymous 7c6966a9c4 Kernel: Add support for text mode terminal 
This probably won't be used at all but it was so simple and made me do
really nice refactorings so i decided to add it :)

This allows moving parts of window around
 2025-04-17 23:14:46 +03:00
Bananymous 88abbd90dc LibC: Fix strncat 
strncat was using strncpy internally which nullpadded dest until n bytes
were written.

also there was no terminating null byte added if src was shorter than n
bytes
 2025-04-17 23:12:40 +03:00
Bananymous bdbde25784 LibC: Rewrite environ handling 
environ is only allocated on heap when you insert new variables.

environment variables are only `free`'d if they are `malloc`'d by libc
 2025-04-16 21:08:01 +03:00
Bananymous ee9e941a56 LibC: Implement getitimer 2025-04-15 23:35:25 +03:00
Bananymous ac90800c3c Kernel/LibC/DynamicLoader: Implement thread local storage 
For some reason this does not work on 32 bit version, so it is disabled
on that platform. I'll have to look into it later to find the bug :)
 2025-04-15 23:33:39 +03:00

Bananymous a933fabb86 Kernel: Define constant USERSPACE_END 
This should be used for userspace generic allocations. Currently I used
KERNEL_OFFSET, but I want to limit userspace to the actual lower half of
the address space
 2025-04-15 23:31:17 +03:00
Bananymous 36baf7b0af Kernel/LibC/DynamicLoader: Update process start ABI

without libc needing to malloc it at startup
 2025-04-15 23:05:52 +03:00
