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.

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.

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.

Andreas Kling
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.

Linus Groh
9882848e0b Kernel: Define IF_NAMESIZE in net/if.h 
This makes the _socket module from the Python port build. :^)

7b3642d08c Kernel: Mark sys$lseek() as not needing the big lock

the big lock.

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 :^)

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

4916c892b2 Kernel/Profiling: Add profiling to read syscall 
Syscalls to read can now be profiled, allowing us to monitor
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.

95df924e0e Kernel: Remove EWHYTHO error code :^) 
This error code was a hack for catching error handling mistakes in the
kernel. It's no longer used anywhere.

f51834d610 Kernel: Allow backspace '\b' to be remapped 
Previously, one could put '\b' in a keymap, but in non-Terminal
applications, it would just insert a literal '\b' character instead of
behaving like backspace. This patch modifes
`visible_code_point_to_key_code` to include backspace, as well as
renaming it to `code_point_to_key_code` since '\b' is not a visible
character. Additionally, `KeyboardDevice::key_state_changed` has been
rearranged to apply the user's keymap before checking for things like
caps lock.

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.
