Bananymous 92862fdf39 LibC: Implement nan{,f,l} as functions 
One port was using function pointers to these functions so macros don't
work.

Bananymous a356d90445 LibC: Fix libc compilation for 32 bit target 2024-11-04 10:51:31 +02:00
Bananymous f4be37700f Kernel/userspace: rework floating point math 
SSE is now unconditionally enabled any where and most of math.h is now
actually implemented. using __builtin_<func> lead to many hangs where
the builtin function would just call itself.

Bananymous 2464fccadd LibC: Fix *scanf consuming extra characters 2024-10-19 12:43:23 +03:00
Bananymous 88b8ca5b29 LibC: Fix some string functions 
I was not casting some required values to char or handling length of
zero

Bananymous fdddb556ae LibC: Implement system() more properly 
Old implementation did not ignore and block needed signals
 2024-10-13 22:03:15 +03:00
Bananymous e4982a1a5c LibC: Fix printf with alternate format and zero values 2024-09-26 15:25:16 +03:00
Bananymous 4e9f39384a LibC: Initialize libc only once 
This was breaking stuff with dynamic loader initializing libc and main
executable reinitializing it later :D
 2024-09-24 17:56:12 +03:00
Bananymous e431e90b20 Kernel/LibC: Implement all chown family function with fchownat 2024-09-17 18:35:01 +03:00

 2024-09-17 16:16:47 +03:00
Bananymous 7177da7d62 LibC: Implement dummy get_rusage 
One port seems to use this function. This dummy just reports no used CPU
time for current process nor children
 2024-09-17 15:59:22 +03:00
Bananymous d88ee5c9ee Kernel/LibC: Implement `creat` with `open` 
This allows getting rid of unnecessary SYS_CREATE. Directory creation
still has its own syscall, but I could combine it with SYS_OPEN also.
 2024-09-17 15:55:53 +03:00
Bananymous 467ac6c365 Kernel/LibC: Implement SOCK_CLOEXEC and SOCK_NONBLOCK

dynamic linking was complaining about these not existing

Bananymous 500f774b7f LibC: Add a lot of stub implementations for different libc functions

- syslog
- getrusage
- mlock
- mprotect
- getpeername
- shutdown
- tzset
- mktime

that they are not available
 2024-08-22 14:47:59 +03:00
Bananymous 25a47f0df3 LibC: Implement ungetc() 
I didn't really test this, but I think this implementation does what it
needs to :)

Bananymous 5197000124 LibC: Fix qsort for types bigger than 64 bytes 2024-08-11 18:00:05 +03:00
Bananymous a5a097fa4a Kernel/LibC: Add initial pseudo terminal support 
This patch implements posix_openpt() and ptsname()

grantpt() and unlockpt() are left in LibC as stubs, as posix_openpt
currently does all of the needed work.
