83e78648e4 LibC: fgets() should return null on 0-length EOF reads. 2019-02-26 22:32:51 +01:00

a356746d04 Compat work towards porting vim. 2019-02-26 15:57:59 +01:00

2e5b9d318f Kernel: Simplify ELF loading a bit. 
Instead of iterating over the sections and memcpy()ing per-section,
do all the copying based on program headers instead.

c80182f81f WindowServer: Add 1920x1080 resolution option. 
Because it's fun to go fullscreen on my development machine. :^)

e0c1541847 Compat work towards making bash-5.0 build with less patches. 
Hacked implementations of sigsetjmp() and siglongjmp(). I didn't know about
these APIs until just now, but I hope I got them right.

4a5b474f1d LibC: Install crt0.o into /usr/lib 2019-02-26 13:36:26 +01:00

3f29a12d90 More compat work. Rename libraries from LibFoo.a => libfoo.a 
This makes it more straightforward to build a cross-compiler toolchain.
Also move math stuff from LibC to LibM.

cccc8d8aeb More compat work. 
Move syscall to int 0x82 since using int 0x80 was kinda prone to fork bombs
when building things on Linux. :^)

f6b41d166d WindowServer: Reduce resize related debug spam. 2019-02-26 12:47:45 +01:00

c90962b842 LibGUI: Make toolbars a bit bigger by default. 2019-02-26 11:14:35 +01:00
Andreas Kling
9444ed0117 LibGUI: Remove gradient from the default button style. 
Buttons actually look nicer without the gradient. :^)

88e77fe3af WindowServer: Bump height of window titlebars and menus from 16 to 18. 2019-02-26 11:04:14 +01:00
Andreas Kling
ae90043424 WindowServer+LibGUI: Send the window size along with Paint server messages. 
This way GWindow doesn't need to do synchronous IPC to fetch the appropriate
size for the window's backing store. This is mostly only relevant during
live resize.

1effe70543 WindowServer+LibGUI: Fix global mouse tracking with recursive widget trees. 
Also avoid sending multiple copies of mouse events to global trackers.
 2019-02-26 10:34:05 +01:00
Andreas Kling
2fb3fa7f69 WindowServer: Add a simple CPU usage graph to the global menu bar. 
This is pretty cute and helps me spot when something's chewing up CPU.

b341cab9cc WindowServer: Only invalidate the menubar rect when an app changes menubar. 2019-02-26 01:07:10 +01:00
Andreas Kling
51a3f20445 FileManager: Don't crash when clicking on a forbidden directory. 2019-02-26 00:59:37 +01:00

d77f8ba413 WindowServer: Make message receivers be weak pointers. 2019-02-26 00:54:10 +01:00

95cfa49f1b LibGUI: Make event receivers be weak pointers. 2019-02-26 00:51:49 +01:00

9624b54703 More moving towards using signed types. 
I'm still feeling this out, but I am starting to like the general idea.

beda478821 Kernel: Make syscalls that take a buffer size use ssize_t instead of size_t. 
Dealing with the unsigned overflow propagation here just seems unreasonably
error prone. Let's limit ourselves to 2GB buffer sizes instead.
 2019-02-25 21:21:12 +01:00
Andreas Kling
5af4e622b9 Kernel: Add KResult and KResultOr<T> classes. 
The idea here is to combine a potential syscall error code with an arbitrary
type in the case of success. I feel like this will end up much less error
prone than returning some arbitrary type that kinda sorta has bool semantics
(but sometimes not really) and passing the error through an out-param.

This patch only converts a few syscalls to using it. More to come.

901b7d5d91 Fix a bunch of compiler warnings. Not all, but a lot. 2019-02-25 19:05:51 +01:00
Andreas Kling
15fb917f28 Convert more RetainPtr use to Retained. 2019-02-25 16:04:08 +01:00
Andreas Kling
2cfcbdc735 AK: Add Retained<T>, like RetainPtr, but never null. 
Also use some Clang attribute wizardry to get a warning for use-after-move.

0b957ed2b1 Some compat work towards making GCC's libstdc++ build. 2019-02-25 10:05:32 +01:00

93c0dfd1d7 LibC: A bunch of compat work towards porting GCC. 2019-02-24 15:20:07 +01:00
Andreas Kling
9fd4f4862b Kernel: Make dump_backtrace() kinda sorta work. 2019-02-24 14:51:48 +01:00
Andreas Kling
d218686c0a Ext2FS: Don't copy more than sizeof(ext2_inode) bytes of raw inode data. 
Some file systems have inodes larger than sizeof(ext2_inode) so this would
stomp all over unrelated data.
 2019-02-24 14:24:04 +01:00

a7a456002e LibC: Enough compat work to make binutils-2.32 build and run. 2019-02-23 17:24:50 +01:00

afa6f88039 Throw away the Clock app since we now have a clock in the menubar. :^) 2019-02-22 10:42:29 +01:00

f98dcbf1d6 Kernel: Respect the process umask in open() and mkdir(). 2019-02-22 02:39:13 +01:00
Andreas Kling
6d3e12899b Kernel: Pass process arguments directly on the stack. 
Get rid of the convoluted get_arguments and get_environment syscalls.
This patch also adds a simple /bin/env that just prints its environment.
 2019-02-22 01:55:22 +01:00
Andreas Kling
e969419202 Kernel: Don't allocate and discard an extra stack for every process. 2019-02-22 00:27:06 +01:00
Andreas Kling
b30773638e Userland: Minor tweaks in /bin/su 2019-02-21 23:49:16 +01:00
Andreas Kling
920e8e58ed Kernel+Userland: Implement setuid() and setgid() and add /bin/su 
Also show setuid and setgid bits in "ls -l" output. :^)
 2019-02-21 23:38:10 +01:00
Andreas Kling
6071a77e8e Userland: Remove the /bin/sh greeting. It was cute but spammy. 2019-02-21 23:34:14 +01:00
Andreas Kling
8b64f213a1 Kernel: sigpending() and sigprocmask() should validate memory writes. 2019-02-21 21:33:52 +01:00
Andreas Kling
19acb2baf7 Kernel: Add file permission checks to link() syscall. 
Also use the new name, not the old name, for the new link, duh.
 2019-02-21 17:05:32 +01:00
Andreas Kling
a624fe06b8 Kernel: Add file permission checks to utime() syscall. 2019-02-21 16:37:41 +01:00
Andreas Kling
f0a869ea50 Kernel: Process::cwd_inode() should return a reference. 
There's always a current working directory inode.
 2019-02-21 16:19:07 +01:00
Andreas Kling
ce3b548077 Kernel: Separate VFS stat() from open(). 
It was very confusing that you had to open a FileDescriptor in order to stat
a file. This patch gives VFS a separate stat() function and uses it to
implement the stat() and lstat() syscalls.
 2019-02-21 16:09:12 +01:00

f5f136931a Kernel: Start adding various file system permission checks. 
Fail with EACCES in various situations. Fix userland bugs that were exposed.
