Bananymous 85f200bd86 LibC: Add sched_get_priority_{min,max}

Bananymous a9f58e96d2 LibC: Add endian.h
This is part of POSIX issue 2024 and some software depends on it

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 :(

How was i doing everything so wrong :D
2025-06-03 16:36:39 +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 5a6b43fc90 LibC: Remove debug printing from getnameinfo 2025-06-02 11:39:18 +03:00
Bananymous 317f413746 LibC: Implement very hacky posix_memalign

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 c957f1ddca LibC: Cleanup pthread code and add some pthread_attr functions
errno, pthread cleanup and pthread id are now stored in uthread. This
allows using these without TLS
2025-06-01 13:48:03 +03:00
Bananymous 423386a052 LibC: Add memory.h that just includes string.h
There are a lot of ports trying to include memory.h. This is not posix
but glibc just includes string.h. I think this is just to privide mem*
functionss...?
2025-06-01 13:48:03 +03:00
Bananymous b1065fa01d Kernel/LibC: Add ppoll syscall and fix poll

Bananymous ee7c9b6731 LibC: Add simple `getnameinfo`

string.

yday calculation was off so results were always off for march-december

Bananymous a8f8d27f4e LibC: Implement basic tzset()

Bananymous 1bcd1edbf5 Kernel/LibC: Implement basic epoll
This implementation is on top of inodes instead of fds as linux does it.
If I start finding ports/software that relies on epoll allowing
duplicate inodes, I will do what linux does.

I'm probably missing multiple epoll_notify's which may cause hangs but
the system seems to work fine :dd:

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 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 :)

Bananymous 1ccff9478f LibC: Don't define __tls_get_addr if TLS is disabled
