c081aae9b5 LibC: Rename beep() to sysbeep() to avoid clashing with curses. 2019-05-17 14:32:53 +02:00
Andreas Kling
3cba2a8a78 Kernel: Add a beep() syscall that beeps the PC speaker. 
Hook this up in Terminal so that the '\a' character generates a beep.
Finally emit an '\a' character in the shell line editing code when
backspacing at the start of the line.

8b249bd09b Kernel+Userland: Implement mknod() syscall and add a /bin/mknod program. 2019-05-03 22:59:58 +02:00

d07be1087a Kernel+LibC: Add exit_thread() syscall. 2019-04-29 15:17:20 +02:00

0c898e3c2c Put assertions behind a DEBUG flag to make it easy to build without them. 2019-04-23 21:52:02 +02:00

58240fdb33 Do a pass of compiler warning fixes. 
This is really making me question not using 64-bit integers more.

5c68929aa1 Kernel: Add a systrace() syscall and implement /bin/strace using it. 
Calling systrace(pid) gives you a file descriptor with a stream of the
syscalls made by a peer process. The process must be owned by the same
UID who calls systrace(). :^)

5eedb22834 Sprinkle use of AK::Vector in various places. 
Some of these are less helpful than others. Avoiding a bunch of mallocs
in the event loop wakeup code is definitely nice.

26a06f3fcd Kernel: More work towards POSIX SHM, also add ftruncate(). 2019-04-09 01:10:00 +02:00
Andreas Kling
0058da734e Kernel: Add Inode::truncate(size). 
- Use this to implement the O_TRUNC open flag.
- Fix creat() to pass O_CREAT | O_TRUNC | O_WRONLY.
- Make sure we truncate wherever appropriate.

0c2face7b0 LibC: Add creat(), execvp() resolution, and exec*() environment inheritance. 2019-03-27 01:39:13 +01:00
Andreas Kling
500df578fe LibGUI+Kernel: Add a GLock class (userspace mutex.) 
It's basically a userspace port of the kernel's Lock class.
Added gettid() and donate() syscalls to support the timeslice donation
feature we already enjoyed in the kernel.
 2019-03-25 13:03:49 +01:00
Andreas Kling
31871557e4 LibC: Add ftruncate() stub. 2019-03-24 00:53:39 +01:00
Andreas Kling
e561ab1b0b Kernel+LibC: Add a simple create_thread() syscall. 
It takes two parameters, a function pointer for the entry function,
and a void* argument to be passed to that function on the new thread.

2c3cf22bc9 LibC: A whole bunch of compat work towards porting Lynx. 2019-03-14 15:18:15 +01:00
Andreas Kling
8175d75432 LibC: Implement getlogin(). 2019-03-10 03:15:36 +01:00

eda0866992 Add a C++ helper class for working with shared buffers. 
This is a bit more comfortable than passing the shared buffer ID manually
everywhere and keeping track of size etc.

2c5a378ccc Kernel+Userland: Add symlink() syscall and add "-s" flag to /bin/ln. 
It's now possible to create symbolic links! :^)

This exposed an issue in Ext2FS where we'd write uninitialized data past
the end of an inode's content. Fix this by zeroing out the tail end of
the last block in a file.
 2019-03-02 01:52:24 +01:00
Andreas Kling
1d2529b4a1 Add chown() syscall and a simple /bin/chown program. 2019-02-27 12:32:53 +01:00
Andreas Kling
cccc8d8aeb More compat work. 
Move syscall to int 0x82 since using int 0x80 was kinda prone to fork bombs
when building things on Linux. :^)
 2019-02-26 12:57:02 +01:00

901b7d5d91 Fix a bunch of compiler warnings. Not all, but a lot. 2019-02-25 19:05:51 +01:00
Andreas Kling
a7a456002e LibC: Enough compat work to make binutils-2.32 build and run. 2019-02-23 17:24:50 +01:00
Andreas Kling
7d288aafb2 Kernel: Add link() syscall to create hard links. 
This accidentally grew into a little bit of VFS cleanup as well.

Also add a simple /bin/ln implementation to exercise it.

640360e958 Move WindowServer to userspace. 
This is a monster patch that required changing a whole bunch of things.
There are performance and stability issues all over the place, but it works.
Pretty cool, I have to admit :^)
 2019-02-17 00:13:47 +01:00
Andreas Kling
4ea28bf0a5 Kernel: Add a simple shared memory API for two processes only. 
And use this to implement shared bitmaps between WindowServer and clients.
 2019-02-16 12:13:43 +01:00

736e852525 LibC: Implement enough missing stuff to get bash-5.0 running. :^) 2019-02-08 02:38:21 +01:00

2ac697ca09 LibC: execl() forgot to add the null sentinel to argv. 2019-02-08 00:12:35 +01:00

dddd0e7b03 Get nyancat nyanning in Serenity. 
I found a cute program that renders an animated nyancat in the terminal.
This patch adds enough hackery to get it working correctly. :^)

c2adfd0e2d LibC: Implement various things to get GNU bc building and running. 
Looks like that's all we needed, and bc now runs. :^)

c30e2c8d44 Implement basic chmod() syscall and /bin/chmod helper. 
Only raw octal modes are supported right now.
This patch also changes mode_t from 32-bit to 16-bit to match the on-disk
type used by Ext2FS.

I also ran into EPERM being errno=0 which was confusing, so I inserted an
ESUCCESS in its place.

c95228b128 Add support for removing directories. 
It's really only supported in Ext2FS since SynthFS doesn't really want you
mucking around with its files. This is pretty neat though :^)

I ran into some trouble with HashMap while working on this but opted to work
around it and leave that for a separate investigation.

267a903dd0 Terminal: Redraw entire line if any of its characters are dirty. 
This means we only have to do one fill_rect() per line and the whole process
ends up being ~10% faster than before.

Also added a read_tsc() syscall to give userspace access to the TSC.

8d36c8f0d8 LibC: Tweak execvp() and execve() prototypes. 2019-01-23 17:09:00 +01:00
Andreas Kling
69a3aecf6b LibC: Add vsnprintf(), snprintf(), execvp() and abs(). 2019-01-23 06:35:34 +01:00
Andreas Kling
bda0c935c2 Add unlink() syscall and /bin/rm. 
This patch adds most of the plumbing for working file deletion in Ext2FS.
Directory entries are removed and inode link counts updated.
We don't yet update the inode or block bitmaps, I will do that separately.
 2019-01-22 07:03:44 +01:00
Andreas Kling
f70136a324 Kernel: Support open() with O_CREAT. 
It's now possible to create zero-length files! :^)
Also hook up the new functionality in /bin/touch.
 2019-01-22 00:58:56 +01:00

3a0a8848fb Make syscall invocations look pleasant. 
Old: Syscall::invoke(Syscall::SC_foo, (dword)arg1, (dword)arg2)
New: syscall(SC_foo, arg1, arg2)
 2018-12-21 03:02:06 +01:00
Andreas Kling
ed7ae6c02c Add sync() syscall and a /bin/sync. 
It walks all the live Inode objects and flushes pending metadata changes
wherever needed.

This could be optimized by keeping a separate list of dirty Inodes,
but let's not get ahead of ourselves.

303577df16 Various stubs while trying to get an old coreutils to build. 2018-11-17 15:56:09 +01:00
Andreas Kling
9d05f6b7a7 Make bash-2.05b build with minimal changes. 
This is really neat. :^)
 2018-11-17 00:14:07 +01:00
Andreas Kling
c99f8af66d Add ioctl() and reimplement tcsetpgrp/tcsetpgrp as ioctls. 2018-11-16 13:13:50 +01:00
Andreas Kling
d5d45d1088 Rage hacking to get bash to run. It finally runs. So cool! :^) 2018-11-11 15:38:07 +01:00
Andreas Kling
e48182d91b Add setvbuf(), setlinebuf(), setbuf(). 2018-11-11 10:11:09 +01:00
Andreas Kling
3b2f172d48 A bunch of compat work (mostly stubs but some real implementations, too.) 
Another pass at getting bash-1.14.7 to build. Not that many symbols remain.

0b3e927597 Oops, waitpid() was not passing the options parameter to the kernel. 2018-11-07 10:46:48 +01:00
