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.

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.

Andreas Kling
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.

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.

f47c92bd2e Kernel: Mark serenity_dev_ functions as static
This avoids multiple definition errors when linking software which
may utilize these functions from different compilation units.

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.

e14e919b78 Kernel: Fill some siginfo and ucontext fields on SA_SIGINFO
There's no reason to fill in any of these fields if SA_SIGINFO is not
given, as the signal handler won't be reading from them at all.
2022-03-04 20:07:05 +01:00
Ali Mohammad Pur
4bd01b7fe9 Kernel: Add support for SA_SIGINFO
We currently don't really populate most of the fields, but that can
wait :^)

standard.

filesystem usage by different applications.

b4a7d148b1 Kernel: Expose maximum argument limit in sysconf
Move the definitions for maximum argument and environment size to
Process.h from execve.cpp. This allows sysconf(_SC_ARG_MAX) to return
the actual argument maximum of 128 KiB to userspace.

b1ca39411b Kernel/Devices: Introduce the Device Control Device
This device will assist userspace to manage hotplug events.
A userspace application reads a DeviceEvent entry until the return value
is zero which indicates no events that are queued and waiting for
processing.
Trying to read with a buffer smaller than sizeof(DeviceEvent) results in
EOVERFLOW.
For now, there's no ioctl mechanism for this device but in the future an
acknowledgement mechanism can be implemented via ioctl(2) interface.

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.

69cabb3ead Everywhere: Add serenity_dev_{makedev,major,minor}
Add them in `<Kernel/API/Device.h>` and use these to provides
`{makedev,major,minor}` in `<sys/sysmacros.h>`. It aims to be more in
line with other Unix implementations and avoid code duplication in user
land.
