e383bc6fd8 LibC: Oops, forgot to commit sigsuspend() prototype. 2019-05-21 12:31:14 +02:00
Andreas Kling
3c7b46a85a LibC: Add htonl() and ntohl(). 2019-05-21 02:22:21 +02:00

02033873b7 LibC: Add sigsuspend() stub. 2019-05-21 02:22:02 +02:00

ae470ec955 Kernel: Add getpeername() syscall, and fix getsockname() behavior. 
We were copying the raw IPv4 addresses into the wrong part of sockaddr_in,
and we didn't set sa_family or sa_port.

b3a1671f1a Kernel: Add support for recv() with MSG_DONTWAIT. 
Passing this flag to recv() temporarily puts the file descriptor into
non-blocking mode.

Also implement LocalSocket::recv() as a simple forwarding to read().

5b6e66195b LibC: Add an h_addr macro for old code that doesn't know about h_addr_list. 2019-05-19 19:55:49 +02:00
Andreas Kling
212a263f0a Kernel+LibC: Implement getsockname() syscall. 2019-05-19 19:55:27 +02:00

0eb788d641 LibC: Add stub for fsync(). 2019-05-19 19:54:20 +02:00
Andreas Kling
189b342e6f LibC: Add mmap_with_name() that names the allocation immediately. 
This allows us to skip the separate call to set_mmap_name() in code that
we control, e.g malloc() and GraphicsBitmap.

29863d3815 LibC: unsetenv() should take a const char*, not a char*. 2019-05-19 15:19:48 +02:00

f5234660f6 malloc: Use a Vector with inline capacity for the big block recyclers. 2019-05-18 22:26:01 +02:00

f015798af9 LibC: Implement clock() and add CLOCKS_PER_SEC define. 2019-05-17 20:19:03 +02:00

77dfd419e9 LibCore: Move AK/ArgsParser to LibCore/CArgsParser 
Also rename the classes to match LibCore naming style.
This means that it's no longer incorrectly linked into LibC and Kernel.

c081aae9b5 LibC: Rename beep() to sysbeep() to avoid clashing with curses. 2019-05-17 14:32:53 +02:00

abb7455163 LibC/Shell: Add unsetenv(), and unset builtin calling it in Shell. 2019-05-16 14:32:09 +02:00
Robin Burchell
b2dd12daac LibC: Change putenv (and getenv) to not copy, but directly return the environ values. 
This is in keeping with how putenv should function. It does mean that
the shell's export command now leaks, but that's not a difficult fix.

Contributes to #29.

6f73a549fa LibC: Add struct timespec to time.h 2019-05-16 14:03:49 +02:00

4dad585609 LibC: Allow {AF,PF}_UNIX as well as {AF,PF}_LOCAL 
Seems that these are equivilent. POSIX specifies _LOCAL, but a lot of
software uses _UNIX.

cf41b0ef17 LibC: Add INET_ADDRSTRLEN define 2019-05-16 14:03:49 +02:00
Robin Burchell
619489da62 LibC: Define a SOMAXCONN value in socket.h 
No idea if this is sensible; but some software will look for it.

f0f5dd6cef LibC: Implement str{n}casecmp 2019-05-16 14:03:49 +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.

5f7bb9d072 malloc: Make it possible to recycle big allocation blocks as well. 
This patch makes us recycle up to 8 blocks of 4KB size. This should
probably be extended to handle other sizes.

43604bf71a LibC+Shell: Make system() actually work. 
system() will now fork off a child process and execute the command via
/bin/sh -c. There are probably some things to fix here, but it's a start.

c1b025b5a6 LibC: Oops, I forgot to commit sys/uio.{cpp,h} yesterday. 2019-05-10 17:38:51 +02:00
Andreas Kling
99aead4857 Kernel: Add a writev() syscall for writing multiple buffers in one go. 
We then use this immediately in the WindowServer/LibGUI communication in
order to send both message + optional "extra data" with a single syscall.

81a280da87 Toolchain: Make sure everything ends up in the right place in Root/ 2019-05-08 15:50:24 +02:00

8b249bd09b Kernel+Userland: Implement mknod() syscall and add a /bin/mknod program. 2019-05-03 22:59:58 +02:00
Andreas Kling
9f633a1871 LibC: Add strcoll() and strxfrm(). 
These are obviously not locale-aware implementations, but rather really just
strcmp() and strcpy() with different names. This makes vim build and run :^)

66e401d668 LibC: Tune the number of ChunkedBlocks we keep around empty. 
At the moment, both mmap() and munmap() are kind of slow. Compiling with GCC
was suffering quite badly from munmap() slowness, so let's keep a few more
of the ChunkedBlocks around after they are empty, to avoid having to munmap.
 2019-05-02 18:11:36 +02:00
Andreas Kling
b4e7925e31 LibC: Move full ChunkedBlocks to a separate list in the allocator. 
This way we only check actually usable blocks when trying to satisfy a new
allocation request.
 2019-05-02 17:06:05 +02:00
Andreas Kling
60023ff70b LibC: free() should move kept empty ChunkedBlocks to the end of the list. 
This ensures that we continue allocating from partially-used blocks until
they are full.
 2019-05-02 16:35:57 +02:00
Andreas Kling
658fff195c LibC: free() should return free blocks back to the operating system. 
Okay fine, I'll give them back. But we'll keep 4 blocks per size class on
hand, to reduce churn.

2dc72bb297 LibC: Improve malloc() mmap names somewhat. 2019-05-02 02:58:06 +02:00
Andreas Kling
4291e96991 LibC: Implement a simple freelist-based malloc() with size classes. 
It's not thread-safe yet, and there is lots of room for improvement.
Still it's a lot faster than the first-fit bitmap-based one it replaces.
 2019-05-02 02:35:29 +02:00
Andreas Kling
98a0e10319 LibC: Log all malloc() calls if LIBC_LOG_MALLOC is set. 
This makes it easier to quickly determine if a userspace process is getting
bogged down in memory allocation.

80850e274d LibC: Oops, exit_thread() never returns. 2019-04-29 15:18:21 +02:00
Andreas Kling
d07be1087a Kernel+LibC: Add exit_thread() syscall. 2019-04-29 15:17:20 +02:00

4977fd22b8 Toolchain: Useit.sh finish and added an install target for the libc's Makefile and a bit of ground work for a gcc port 2019-04-29 13:12:20 +02:00
Andreas Kling
95ddca8a52 LibC: Make the malloc()/free() scrubbing runtime optional (default on.) 
Memory returned by malloc() is normally memset with 0x85.
Memory passed to free() is normally memset with 0x82.

These behaviors can now be disabled by setting one or both of
LIBC_NOSCRUB_MALLOC and LIBC_NOSCRUB_FREE in your environment. :^)

f80244399d LibC: Add dummy pthread.h for GCC build. 2019-04-27 21:19:18 +02:00
Andreas Kling
d3fb0a56ed LibC: Make fwrite() buffered. 
This is a really naive implementation that makes fwrite() call fputc()
internally, but it still performs a lot better due to avoiding the write()
syscall every time.

100cb2a237 LibC: Various stdio correctness fixes. 2019-04-27 16:19:11 +02:00

490e89e240 LibC: Add execvpe() and make execvp()'ed children inherit environment. 2019-04-26 03:16:26 +02:00

8effdc807a LibC: Update stdio stream error state in more places. 2019-04-26 00:41:37 +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
Andreas Kling
58240fdb33 Do a pass of compiler warning fixes. 
This is really making me question not using 64-bit integers more.
