Bananymous c957f1ddca LibC: Cleanup pthread code and add some pthread_attr functions

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...?

Bananymous b1065fa01d Kernel/LibC: Add ppoll syscall and fix poll

This adds less overhead on top of poll and adds support for POLLHUP

Bananymous ee7c9b6731 LibC: Add simple `getnameinfo`

 2025-05-28 03:10:01 +03:00
Bananymous 7eade002a7 LibC: Fix `mktime` 
yday calculation was off so results were always off for march-december
 2025-05-28 03:10:01 +03:00
Bananymous a8f8d27f4e LibC: Implement basic tzset() 
I still don't have timezone support so this just sets values to UTC
 2025-05-28 03:10:01 +03:00
Bananymous 356935bd4f LibC: Fix strtou{,l,ll} for negative values

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:

 2025-04-22 08:36:44 +03:00
Bananymous 808c97020a Kernel/LibC: Implement SA_RESTART

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

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

 2025-04-19 02:07:45 +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.

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

Bananymous ac90800c3c Kernel/LibC/DynamicLoader: Implement thread local storage
