f1f3cd58b0 FileSystem: fix errno on lseek() beyond the bounds of a file 
These are all EINVAL. Also remove bogus assert on metadata.size.

c5434e0cfa Kernel: Simplify ELF loader by removing the allocator indirections. 2019-05-16 14:16:08 +02:00

2f4e7edee5 Kernel: Simplify dump_backtrace() API for clients. 
It makes no sense that clients had to worry about whether or not KSyms
were loaded.

7a2da54c07 Only the kernel needs to build with default includes disabled. 2019-05-16 13:40:43 +02:00

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.

ac2a3b65bb makeall: Use set -e to exit on failure 
And pretty the building/installing up a little, rather than a huge chain of &&

01ffcdfa31 Kernel: Encapsulate the Region's COW map a bit better. 2019-05-14 17:31:57 +02:00
Andreas Kling
7c10a93d48 Kernel: Make allocate_kernel_region() commit the region automatically. 
This means that kernel regions will eagerly get physical pages allocated.
It would be nice to zero-fill these on demand instead, but that would
require a bunch of MemoryManager changes.

9e2116ff6b Kernel: Signal stacks are lazily allocated so don't crash in getter. 2019-05-14 12:17:59 +02:00
Andreas Kling
486c675850 Kernel: Allocate kernel signal stacks using the region allocator as well. 2019-05-14 12:06:09 +02:00
Andreas Kling
c8a216b107 Kernel: Allocate kernel stacks for threads using the region allocator. 
This patch moves away from using kmalloc memory for thread kernel stacks.
This reduces pressure on kmalloc (16 KB per thread adds up fast) and
prevents kernel stack overflow from scribbling all over random unrelated
kernel memory.

b7166385de RetroFetch: Add a silly neofetch-like program. 
The idea is to print out various system info suitable for screenshots. :^)

090e14d42c IPv4: Default initialize IPv4Address to 0.0.0.0. 
IPv4Address() didn't initialize which made for some confusing debugging.
 2019-05-10 18:18:54 +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.

bd5c79aff2 LibGUI: Start working on a file picker dialog (GFilePicker). 
Have LibGUI adopt GDirectoryModel from FileManager since it fits perfectly
for the needs of a file picker.

eaf03d4ddb HelloWorld: Add a simple "Hello World!" app showing the basics. 
This also introduces a Demos/ directory where I hope to add cool things.

ba7364b43b Shell: Move line editing to a separate class. 
To be clear, there isn't really any line editing yet. But there is
going to be, so let's have it in its own class.

fe73543d41 Shell: Move the Shell to a separate directory and let's call it "Shell" :^) 2019-05-07 01:12:08 +02:00

72cbcd8e98 Kernel: Dump backtrace on exit() syscall. 
This makes assertion failures a lot more pleasant to investigate.

6228503c16 Kernel: Add a bit of logging in VMObject::inode_size_changed(). 2019-05-04 21:15:59 +02:00

932836e3c7 Kernel: Computing the boot timestamp was a bit broken. 2019-05-04 17:05:42 +02:00

5e938868a2 IPv4: Rename source/destination in socket classes to local/peer. 
It was way too ambiguous who's the source and who's the destination, and it
didn't really follow a logical pattern. "Local port" vs "Peer port" is super
obvious, so let's call it that.

780d2a08c4 IPv4: Save the source address/port together with incoming packet payloads. 
We need the address/port to fill in the out-params in recvfrom().
It should now be more or less possible to create a UDP server. :^)

c4bb9a3ccb sync.sh: Add "-f" option to forcibly regenerate _fs_contents from scratch. 
This might be useful e.g if something goes wrong with the filesystem.

7aba0058ae sync.sh: Don't regenerate _fs_contents from /dev/zero every time. 
This makes sync.sh run a lot faster, especially on slower machines.

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

abb5c890e0 IPv4: Implement bind() for TCP and UDP sockets. 
We can't accept connections just yet, but this patch makes it possible to
bind() to a given source address/port.

03da7046bd Kernel: Prepare Socket for becoming a File. 
Make the Socket functions take a FileDescriptor& rather than a socket role
throughout the code. Also change threads to block on a FileDescriptor,
rather than either an fd index or a Socket.
 2019-05-03 20:15:54 +02:00

34c5db61aa Kernel: Simplify VMObject::is_anonymous(). 
This doesn't need a separate flag. A VMObject is always anonymous if it has
no backing inode.

b8e60b6652 Kernel: Remove unused Region::is_bitmap(). 2019-05-02 23:31:11 +02:00

25ddcd1022 Kernel: Emit systrace events for exit, thread_exit and sigreturn. 
Since these syscalls don't return to caller, we have to emit the trace
events manually.

14ac77131b Kernel: The exit_thread() syscall should unlock the big lock. 
Since exit_thread() never returns, it can't rely on the syscall trap handler
to unlock the big lock before returning.

d07be1087a Kernel+LibC: Add exit_thread() syscall. 2019-04-29 15:17:20 +02:00
Andreas Kling
8cbb7f101f Kernel: Have File virtuals take a FileDescriptor& rather than a Process&. 
This will allow us to implement different behaviors depending on the role
of the descriptor a File is being accessed through.

0a0d739e98 Kernel: Make FIFO inherit from File. 2019-04-29 04:55:54 +02:00

475a17fa4b VFS: Also respect the sticky bit of the new parent in rename(). 
Obviously we should not allow overwriting someone else's files in a sticky
directory either.
 2019-04-28 23:34:33 +02:00
Andreas Kling
e4eca17848 VFS: Implement sticky bit behavior for rename() and unlink(). 
Removing entries from a sticky directory is only allowed when you are either
the owner of the entry, or the superuser. :^)
