1682b0b6d8 Kernel: Remove big lock from sys$set_coredump_metadata 
The only requirement for this syscall is to make
Process::m_coredump_properties SpinlockProtected.

cc411b328c Kernel: Remove big lock from sys$accept4 
The only thing we needed to check is whether `socket.accept()` returns
a socket, and if not, we go back to blocking again.

12b612ab14 Kernel: Mark sys$adjtime() as not needing the big lock 
This syscall works on global kernel state and so doesn't need protection
from threads in the same process.
 2022-04-04 00:42:18 +02:00
Andreas Kling
4306422f29 Kernel: Mark sys$clock_settime() as not needing the big log 
This syscall ends up disabling interrupts while changing the time,
and the clock is a global resource anyway, so preventing threads in the
same process from running wouldn't solve anything.

55814f6e0e Kernel: Mark sys$sched_{set,get}param() as not needing the big lock 
Both of these syscalls take the scheduler lock while accessing the
thread priority, so there's no reliance on the process big lock.

Andreas Kling
36d829b97c Kernel: Mark sys$listen() as not needing the big lock 
This syscall already performs the necessary locking and so doesn't
need to rely on the process big lock.

bc4282c773 Kernel: Mark sys$sendfd() and sys$recvfd() as not needing the big lock 
These syscalls already perform the necessary locking and don't rely on
the process big lock.

b5ef900ccd Kernel: Don't assume paths of TTYs and pseudo terminals anymore 
The obsolete ttyname and ptsname syscalls are removed.
LibC doesn't rely on these anymore, and it helps simplifying the Kernel
in many places, so it's an overall an improvement.

In addition to that, /proc/PID/tty node is removed too as it is not
needed anymore by userspace to get the attached TTY of a process, as
/dev/tty (which is already a character device) represents that as well.

09e644f0ba Kernel: Mark sys$emuctl() as not needing the big lock 
This syscall doesn't do anything at all, and definitely doesn't need the
big lock. :^)

5200cdac43 Kernel: Remove an unused fd_set.h import 
The project appears to build just fine without it, and the explicit use
of `LibC` causes it to conflict with the system-wide `fd_set.h` when
building inside of Serenity.

7543c34d07 Kernel: Mark sys$anon_create() as not needing the big lock 
This syscall is already safe for no-big-lock since it doesn't access any
unprotected data.

baa6ff5649 Kernel: Wrap HIDManagement keymap data in SpinlockProtected 
This serializes access to the current keymap data everywhere in the
kernel, allowing to mark sys$setkeymap() as not needing the big lock.

839d3d9f74 Kernel: Add getrusage() syscall 
Only the two timeval fields are maintained, as required by the POSIX
standard.

182016d7c0 Kernel+LibC+LibCore+UE: Implement fchmodat(2) 
This function is an extended version of `chmod(2)` that lets one control
whether to dereference symlinks, and specify a file descriptor to a
directory that will be used as the base for relative paths.

63760603f3 Kernel+LibC+LibCore: Add lchown and fchownat functions 
This modifies sys$chown to allow specifying whether or not to follow
symlinks and in which directory.

This was then used to implement lchown and fchownat in LibC and LibCore.

8e3d1a42e3 Kernel+UE+LibC: Store address as void* in SC_m{re,}map_params 
Most other syscalls pass address arguments as `void*` instead of
`uintptr_t`, so let's do that here too. Besides improving consistency,
this commit makes `strace` correctly pretty-print these arguments in
hex.

23257cac52 Kernel: Remove sys$select() syscall 
Now that the userland has a compatiblity wrapper for select(), the
kernel doesn't need to implement this syscall natively. The poll()
interface been around since 1987, any code still using select()
should be slapped silly.

Note: the SerenityOS source tree mostly uses select() and not poll()
despite SerenityOS having support for poll() since early 2019...

762e047ec9 Kernel+LibC: Implement sigtimedwait() 
This includes a new Thread::Blocker called SignalBlocker which blocks
until a signal of a matching type is pending. The current Blocker
implementation in the Kernel is very complicated, but cleaning it up is
a different yak for a different day.

0f8483f09c Kernel: Implement new ptrace function PT_PEEKBUF

way.
