95a088fec5 Added a dummy implementation rfork(2) equal to fork(2). 
Note that in my implementation, you share per default, unless you ask.

b3b1f6af66 Make sure that the right bits.h file is always included. 2012-03-27 16:36:55 +02:00

554b2e44cc Added a Page::IsAligned inline function. 2012-03-26 16:46:26 +02:00
Jonas 'Sortie' Termansen
c62eb09cdc Added stubs for pread(2) and pwrite(2). 
These are not implemented yet because the current kernel design is bad.

However, I need the stubs for other code.

1ba4417b19 Removed dead ancient code. 2012-03-22 01:04:27 +01:00

db79994e64 Refactored all the sortix headers into a include directory. 
Also got rid of trailing white space. That corrupted .git/.

Big ass-commit because of recovered .git directory.

ea11c20689 Added a way for discover refcount of Refcounted classes. 2012-03-21 16:20:41 +01:00

0f099c65ca The virtual memory fork code can now handle ENOMEM conditions. 
(forkbombs now don't panic the system!)

c9ab4fa6b4 The sortix vga terminal now can delete tabs and newlines properly. 
A nice little vga attribute array takes care of remembering what indexes
actually contains a character.

14a9149f17 Added detection for an obscure bug to let users know I know about it. 2012-03-18 17:36:31 +01:00

d564603460 Fixed kernel stack overflow and premature EOF in the unix pipe code. 
This usually caused the system to lock up when much data was transferred
over pipes, for instance: $ cd /bin ; cat cat | cat

c7c0fc603a Fixed initial kernel stack being wrong size. 2012-03-17 20:17:12 +01:00
Jonas 'Sortie' Termansen
969c0e8048 Cleaned up sortix/kernel.cpp and it now uses the new coding style. 
All kernel.cpp code related to jssortix was removed as it is not supported
any longer.

4f3e22140c Fixed x64 memory leaks upon process termination. 2012-03-17 18:14:57 +01:00
Jonas 'Sortie' Termansen
0364ce6f55 Added a new COM Port driver. 
Any detected COM ports available as /dev/comN.

It currently utilizes AGAIN to do polling in user-space. This prevents it
from locking up the whole system and makes it respond to the SIGINT hack.

There is also a more reliable and faster polling-blocking mode, but it locks
up the entire system.

The main interrupt mode is broken, perhaps by a bug in VirtualBox.

1ff0321400 Added a stub for Syscall::Yield() which is used by broken code. 
The whole system call interface is currently stupid.

798b421d16 Refactored devfs so new devices can easily be added. 2012-03-17 15:11:35 +01:00

5ec4e33196 Removed the last reference to the old kernel HTTP server. 2012-03-16 16:56:16 +01:00
Jonas 'Sortie' Termansen
2cdeb575f8 Renamed EACCESS to EACCES. 
Stupid POSIX.

5b916b5f63 Added F_SETFL and F_GETFL to fcntl(2). 
This is a bit of a hacky implementation.

868ed43e05 Removed sortix/mxfs. 
It's unbelievable that this piece of dead code survived 8 months of
development on git. It doesn't even work, despit the comment that it
does.
 2012-03-11 18:07:01 +01:00

f01d7951c1 stat(2) now supports directories. 
A bit hackily, though.

f45cf8327a Forgot to enable the /bin /dev hack in sortix/fs/ramfs.cpp. 2012-03-11 17:30:13 +01:00
Jonas 'Sortie' Termansen
cadac5ce2a Moved the /bin and /dev hack into the kernel. 
This makes ls seem less hacky.

8a9a0c58ea Added kernelinfo(2), which reads a kernel information string. 
Currently it lets you query the name of the kernel, its version, and the
build timestamp of the kernelinfo.cpp file.
 2012-03-07 18:04:59 +01:00
Jonas 'Sortie' Termansen
6bcb3d7384 Added stat(2) and fstat(2) in the kernel. 
It's a bit hacky, but it works.

lstat(2) currently redirects to stat(2).
 2012-03-06 13:10:59 +01:00

4b2c22d480 Added access(2). 2012-03-05 15:46:23 +01:00

Jonas 'Sortie' Termansen
5e75f5c428 Added fcntl(3) with FD_GET and FD_SET. 2012-03-04 21:36:40 +01:00
Jonas 'Sortie' Termansen
75b14aa821 Refactored the descriptor table and added FD_CLOEXEC and FD_CLOFORK. 
open(2) now also respects O_CLOEXEC and O_CLOFORK.
 2012-03-04 21:06:49 +01:00
Jonas 'Sortie' Termansen
777fc04682 Added <time.h>, clock_t, and a stub for clock(3). 2012-03-04 18:38:23 +01:00

Removed the older libmaxsi system call.
 2012-03-02 15:00:11 +01:00

93a9ee334d Removed a debug ifdef that isn't used. 2012-03-02 14:25:48 +01:00

cfbbf67247 make CALLTRACE=1 to enable printing primitive calltraces upon panic. 
This won't work with optimizations turned fully on.

Added protection against double panics.
 2012-03-02 14:08:25 +01:00
Jonas 'Sortie' Termansen
6dd0e586ff Added protection against bad addrspace vars and bad Page::Put() calls. 
This will offer protection against the bug fixed in the previous commit.
 2012-03-02 13:51:03 +01:00
Jonas 'Sortie' Termansen
5e5991ce19 Fixed x86 addrspace destroy code calling Page::Put with garbage. 2012-03-02 13:45:33 +01:00
Jonas 'Sortie' Termansen
a7c38cb997 Improved bad currentdir variable panic message. 2012-03-02 00:09:08 +01:00
Jonas 'Sortie' Termansen
9c193777a9 Pipes now return 0 (EOF) if no data and no fds can write. 2012-03-01 14:31:12 +01:00
Jonas 'Sortie' Termansen
b4f47f0f79 Split descriptor_tables.cpp into a gdt.cpp and idt.cpp. 
This was about time, since descriptor_tables was a really bad name!

5162a12d03 Further cleanup and refactoring of the interrupt code. 2012-02-29 23:03:40 +01:00
Jonas 'Sortie' Termansen
0e48b23429 Refactored the interrupt code to make it cleaner and more flexible. 
Added support for hooking directly into an interrupt with your own
interrupt handler.

Jonas 'Sortie' Termansen
cbdf54fcdd Moved SEEK_SET, SEEK_CUR, and SEEK_SET to <sortix/seek.h>. 2012-02-24 17:34:50 +01:00
