Add a list of system and general keyboard shortcuts as well as a list
of tips and tricks to man7 (Miscellanea). Add links to these in the
Help-index to aid discoverability for new users.
by making them `monospace` in the Help page, and bold in the manual.
This helps to quickly find out where the keyboard controls are in the
manual when skimming its contents.
The LUN.target_id parameter points to a NVMe Namespace which starts from
1 and not 0. Fix the document to reflect the same while addressing a
nvme device in the boot parameters
These symlinks' only purpose was to be copied into the rootfs along with
the rest of Base. Instead of storing symlinks to files that either
don't exist in the Base directory, or point to an absolute path outside
of the serenity folder, move these symlinks into the
build-root-filesystem.sh script.
This subdirectory is meant to hold all constant data related to the
kernel. This means that this data is never meant to updated and is
relevant from system boot to system shutdown.
Move the inodes of "load_base", "cmdline" and "system_mode" to that
directory. All nodes under this new subdirectory are generated during
boot, and therefore don't require calling kmalloc each time we need to
read them. Locking is also not necessary, because these nodes and their
data are completely static once being generated.
The patch also contains modifications on several classes, functions or
files that are related to the `JPGLoader`.
Renaming include:
- JPGLoader{.h, .cpp}
- JPGImageDecoderPlugin
- JPGLoadingContext
- JPG_DEBUG
- decode_jpg
- FuzzJPGLoader.cpp
- Few string literals or texts

I just got bit by this type of bug in a different project, and was
wondering whether Serenity has this problem, too. See also:

This filesystem is based on the code of the long-lived TmpFS. It differs
from that filesystem in one keypoint - its root inode doesn't have a
sticky bit on it.
Therefore, we mount it on /dev, to ensure only root can modify files on
that directory. In addition to that, /tmp is mounted directly in the
SystemServer main (start) code, so it's no longer specified in the fstab
file. We ensure that /tmp has a sticky bit and has the value 0777 for
root directory permissions, which is certainly a special case when using
RAM-backed (and in general other) filesystems.
Because of these 2 changes, it's no longer needed to maintain the TmpFS
filesystem, hence it's removed (renamed to RAMFS), because the RAMFS
represents the purpose of this filesystem in a much better way - it
relies on being backed by RAM "storage", and therefore it's easy to
conclude it's temporary and volatile, so its content is gone on either
system shutdown or unmounting of the filesystem.
I used this utility to check if the possible TGA images' cases for
different origins (explictly the Y origin) are generating the same
bitmap, as I felt that my eyes are not a good-enough measurement tool
for this kind of task.
This might be useful in the future for testing other implementations so
I rather have this nice utility in our codebase.
We do not want to move POSIX utilities into subsections since they have
standard names, but we can do whatever we want with Applications :^).
This is particularly advantageous as many applications contain several
images, which declutters the man1 directory.
We've had quite some instances of people reintroducing these kinds of
links because they didn't know about the "new" help:// scheme. This
check should now prevent that from happening, though it might in rare
circumstances trigger a false positive.
The setting of scan code set sequence is removed, as it's buggy and
could lead the controller to fail immediately when doing self-test
afterwards. We will restore it when we understand how to do so safely.
Allow the user to determine a preferred detection path with a new kernel
command line argument. The defualt option is to check i8042 presence
with an ACPI check and if necessary - an "aggressive" test to determine
i8042 existence in the system.
Also, keep the i8042 controller pointer on the stack, so don't assign
m_i8042_controller member pointer if it does not exist.
This was a plain-looking test app for debugging mouse events.
Mouse events work now, and if we want mouse testing facilities, they
can be added to MouseSettings instead.
This utility lets a user to figure out what are the dependency libraries
for an ELF dynamic object, whether it's a dynamically loaded executable
or dynamically loaded library.
Check if the process we are currently running is in a jail, and if that
is the case, fail early with the EPERM error code.
Also, as Brian noted, we should also disallow attaching to a jail in
case of already running within a setid executable, as this leaves the
user with false thinking of being secure (because you can't exec new
setid binaries), but the current program is still marked setid, which
means that at the very least we gained permissions while we didn't
expect it, so let's block it.
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
This utility essentially creates a filesystem sandbox for a specified
command, so it can be tested with only the unveiled paths the user
specifies beforehand.
