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 d36b64e0c8 LibImage: name color to u32 function to to_argb from to_rgba

Bananymous 50a3533322 LibInput: Add value for ESC in key_to_utf8_ansi
This allows exiting vim when using this function for key mappings :D
2024-09-24 18:08:34 +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 1280528e4e BuildSystem: Use -O2 for all libraries
I don't know why I had not specified optimization level for libraries.
Only LibImage was using explicit -O3. LibImage doesn't need O3 anymore
as O2 seems to be around the same speed.

Bananymous e431e90b20 Kernel/LibC: Implement all chown family function with fchownat 2024-09-17 18:35:01 +03:00

This patch gets rid of 2 unnecessary syscalls!
2024-09-17 16:38:01 +03:00
Bananymous 708a720d9d Kernel: Remove SYS_OPEN
This can be done with SYS_OPENAT with fd set to AT_FDCWD
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 a084f83f4c Kernel: Rework kernel-side ELF loading
ELFs are now loaded as MemoryRegions so they don't need special handling
anywhere. This also allows file backed COW optimizations to work. This
was not the case before.

This patch removes now obsolete LoadableELF and unused ELF files from
LibElf.
2024-09-15 23:57:34 +03:00
Bananymous 1a24d1839f LibInput: KeyEvent to ansi string now handles delete key
This allows Terminal emulator to also handle delete key.

The value of `\0x7F` may be wrong as qemu's serial console seems to be
sending `\e[3~`

Bananymous 4189a1c729 LibC: Make _init and _fini weak symbols
These seem to be missing sometimes when making shared executables
2024-09-11 14:39:07 +03:00
Bananymous a07cbabcb3 LibC: Define function sizes for setjmp and longjmp
dynamic linking was complaining about these not existing

2024-09-02 21:28:02 +03:00
Bananymous 5f92807fdd userspace: Allow building without SSE
I had added changes that had broken compilation without sse support
2024-09-02 21:25:00 +03:00
Bananymous 700c3444f5 LibELF: Add more values and macros for interpreting fields 2024-09-02 20:40:38 +03:00
Bananymous 2ae2ede0b2 LibELF: Add value definitions for DT_ 2024-08-30 15:35:01 +03:00
Bananymous 8da2f12ba6 Kernel: Only load program headers of interpreter if its present
I was loading program headers of both executable and interpreter but
that is incorrect. The interpreter will itself load the program headers
of the executable.
2024-08-28 21:19:37 +03:00
Bananymous 57300687ff LibC: Cleanup and fix missing LibC headers 2024-08-28 17:07:58 +03:00

Bananymous 500f774b7f LibC: Add a lot of stub implementations for different libc functions
some ports want to link against these, but they are not ever called
based on simple testing

This patch adds stubs for
- openlog
- 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 :)
2024-08-12 19:14:55 +03:00
Bananymous 60b4d90608 LibGUI: Add Window::get_pixel()

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.

binutils seems to need access to the internal type and uses this name
for lookup.
2024-08-09 16:55:52 +03:00
Bananymous 0c8cae4cc3 LibC: Move ioctl to <sys/ioctl.h>
Some ports seem to be assuming that ioctl exists there and not in
stropts.h

Bananymous 6fedf06150 LibC: Implement {sig,_,}{longjmp,setjmp} 2024-08-09 15:58:56 +03:00
Bananymous 44f0ec601f Kernel: Expose /proc/meminfo and fix /proc/<pid>/meminfo
Thread was unconditionally calling <stack>->size() without validating
that the stack actually exists
2024-08-09 15:58:56 +03:00
Bananymous 2a659a9d03 BuildSystem: Fix enable sse definition
__enable_sse was never actually defined for any targets. This also adds
__arch definition for libc (so `utsname` works).
2024-08-09 15:52:42 +03:00
Bananymous 3b23458ecc LibC: Start work on locales
This patch adds 2 locales, POSIX locale and UTF8 locale.

comparison respectively.

2024-08-07 17:01:35 +03:00
Bananymous fe94d6cf89 LibC: Implement dummy rename() so vim can save files
vim calls rename when saving a file. This patch adds dummy
implementation that only works for regular files and does a copy instead
of proper rename.

Bananymous edc30cd71d LibC: Compile without exceptions
This allows libc to not require __gxx_personality_v0. I can maybe add
C++ back to libc... :D I don't know why I did not research earlier what
this symbols was used for
2024-07-31 23:33:41 +03:00

Bananymous e52dac3b25 LibC: Implement tmpnam()
This implementation is not really spec compliant as rand() does not

Bananymous 3ab1214012 LibC: Fix _toupper and _tolower definitions
They were using C++ global namespace, which of course does not exist for
C targets.

Bananymous af4b138094 Kernel/LibC: Implement realpath
realpath is implemented as a syscall. This is not really required but it
was the easiest way to get it working as there is already path
canonicalization at kernel level.
