Bananymous 96f3efbf86 LibC: Fix enviroment variable allocation 2025-06-28 20:25:35 +03:00
Bananymous e8491b34b8 Kernel/LibC: Rework TIOC{G,S}WINSZ more linux like 
Userspace can freely set terminal size, kernel just updates it when for
example new font is loaded. Also SIGWINCH is now sent by kernel instead
of userspace.
 2025-06-28 19:40:54 +03:00
Bananymous f26a445ce6 LibC: Make malloc actually allign to s_malloc_default_align boundary 2025-06-28 16:55:13 +03:00

Bananymous 397219c22e LibC: Implement very hacky dlopen/dlsym/dclose 
If ELF loading fails, this will just crash the program :D

And there is no support for RTLD_LOCAL

Bananymous 85f200bd86 LibC: Add sched_get_priority_{min,max} 
I don't support priority scheduling so these are just no-ops
 2025-06-28 16:55:13 +03:00
Bananymous 0f2c02fb04 LibC: Add stubs for pthread_{get,set}schedparam 2025-06-28 16:55:13 +03:00

These were added in POSIX issue 8
 2025-06-17 13:56:30 +03:00
Bananymous a9f58e96d2 LibC: Add endian.h 
This is part of POSIX issue 2024 and some software depends on it
 2025-06-17 13:15:42 +03:00
Bananymous 7651ca747d LibC: Allow searching null char with wcschr 2025-06-16 15:09:55 +03:00

Bananymous f9451915b9 LibC: Use `pause` in pthread spinlock locking 2025-06-16 15:07:58 +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 :(
 2025-06-06 16:27:07 +03:00
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 84b1f3990c LibC: Fix getnameinfo 
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

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
 2025-06-02 11:39:18 +03:00
Bananymous e9f8471a28 BAN: Return UTF::invalid from byte_length instead of 0 2025-06-02 11:39:18 +03:00

Bananymous 2b48933f29 LibC: Implement all functions from complex.h 2025-06-01 13:48:03 +03:00
Bananymous 4ac6cbe70e LibC: Add some missing wchar.h functions 
isw* functions are just wrappers to is*
tow* functions are just wrappers to to*
 2025-06-01 13:48:03 +03:00
Bananymous cc07c3df94 LibC: Add basic strxfrm{,_l} 2025-06-01 13:48:03 +03:00

Again this code is not tested but *feels* right :D
 2025-06-01 13:48:03 +03:00

This code is not tested at all but it looks correct xD

Bananymous 56fdf6002c Kernel/LibC: Implement pthread_kill 2025-06-01 13:48:03 +03:00
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 
poll is now using its own syscall instead of wrapping aroung pselect.
This adds less overhead on top of poll and adds support for POLLHUP
 2025-06-01 13:48:03 +03:00
Bananymous 1bd454b8fd Kernel/LibC: Implement utime* family functions 
This patch adds *working*

 - utimes
 - utimensat
 - futimens
 2025-06-01 13:48:03 +03:00

Bananymous ee7c9b6731 LibC: Add simple `getnameinfo` 
This doesn't actually do any name resolution but just formats input to
string.
 2025-05-28 03:10:01 +03:00
Bananymous 4721344518 LibC: Don't fail `getaddrinfo` if node is null 2025-05-28 03:10:01 +03:00

Bananymous 8aa4e4ff1e LibC: Implement `clearenv` 
This is GNU extension but seems nice to have :D
 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 
Also set endp if base is invalid
 2025-05-28 03:10:01 +03:00
Bananymous bce3dd045f LibC: Fix strncat return value 2025-05-28 03:10:01 +03:00

Bananymous ddcf414107 LibC: Fix netinet/in.h and arpa/inet.h definitions 2025-05-28 03:10:01 +03:00
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:

second string

Old code was always returning off by one
 2025-04-22 09:55:38 +03:00
Bananymous 96740d6be4 LibC: Make `inet_addr` spec compliant 
I was not doing any error checking, basically i validated anything that
started with atleast a single digit.
 2025-04-22 09:40:46 +03:00
Bananymous 33a0f562d3 resolver: Add support for CNAME 
Also rework resolver's send format and convert test-tcp and nslookup to
use getaddrinfo
 2025-04-22 08:36:44 +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 5c9710c78b LibC: Implement `strcoll_l` 2025-04-22 00:48:26 +03:00

Bananymous 543bb3cc4b LibC: Rework malloc locking add proper realloc 2025-04-21 20:29:28 +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 265b4c2b22 LibC: Implement `thread_equal` 2025-04-20 03:27:16 +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 1ccff9478f LibC: Don't define __tls_get_addr if TLS is disabled 
This makes linking fail if something tries to use TLS :)
 2025-04-20 03:11:41 +03:00
Bananymous 85f9b585f5 LibC: Don't yield on `pthread_spin_lock`

 2025-04-19 21:16:11 +03:00
Bananymous 2d19b5074e LibC: Implement some missing wchar functions 2025-04-19 20:56:41 +03:00
