Only users in this group can access the screen, mouse and keyboard.
|
|
|
|
This fixes an issue where anyone could snoop on the virtual consoles.
|
|
Make these directories accessible to root only. Unprivileged users have
no need to look at the kernel binary or kernel modules.
|
|
This requires gcc8 from ports to build the Toolchain.
|
|
Let's lock down access to the kernel symbol table, since it trivializes
learning where the kernel functions are.
Of course, you can just build the same revision yourself locally and
learn the information, but we're taking one step at a time here. :^)

The LinkDemo program calls dlopen/dlsym/dlclose to try and load
a dyanmic library from /usr/lib. It read a global variable and
calls a global function (extern "C" of course :) ).
There a few hacks left in the LinkLib dynamic library, however.
In order to get the linker to stop complaining, we have to use
-nostartfiles -ffreestanding otherwise it will link crt0.o to our
shared object, which is definitely not right as the _init function
for a main program (that calls main) is not suitable for our lib
|

/bin/ping is now setuid-root, and will drop privileges immediately
after opening a raw socket.

This patch introduces the second MenuApplet: Audio. To make this work,
menu applet windows now also receive mouse events.
There's still some problem with mute/unmute via clicking not actually
working, but the call goes from the applet program over IPC to the
AudioServer, where something goes wrong with the state change message.
Need to look at that separately.
Anyways, it's pretty cool to have more applets running in their own
separate processes. :^)

We begin with a simple treeview that shows a recorded profile.
To record and view a profile of a process with <PID>, simply do this:
$ profile <PID> on
... wait while PID does something interesting ...
$ profile <PID> off
$ cat /proc/profile > my-profile.prof
$ ProfileViewer my-profile.prof
|
|
This implements the WSCPUMonitor functionality in a separate process.
|
|
This is one of the most common apps I bring up, yet there's no handy
alias for it? Silly :^)
|
|
Kernel modules can now be unloaded via a syscall. They get a chance to
run some code of course. Before deallocating them, we call their
"module_fini" symbol.
|
|
It's now possible to load a .o file into the kernel via a syscall.
The kernel will perform all the necessary ELF relocations, and then
call the "module_init" symbol in the loaded module.
|
|
We should just get good enough to run "neofetch" or something like that
instead of having this half-baked thing.
|
|
This patch adds ProtocolServer, a server that handles network requests
on behalf of its clients. The first protocol implemented is HTTP.
The idea here is to use a plug-in architecture where any number of
protocols can be added and implemented without having to mess around
with each client program that wants to use the protocol.
A simple client API is provided through LibProtocol::Client. :^)

The Launcher's functionality has been replaced by the app shortcuts in
the system menu.
There were various window management hacks to ensure that the launcher
stayed below all other windows while also being movable, etc.
|
|
Ports/.port_include.sh, Toolchain/BuildIt.sh, Toolchain/UseIt.sh
have been left largely untouched due to use of Bash-exclusive
functions and variables such as $BASH_SOURCE, pushd and popd.
|
|
This will be fun. :^)
|
|
The very first release of the Hex Editor for Serenity.
|
|
This was inevitable. :^)
|
|
This is a neat simple app that can display the Serenity manual ^)
|
|
This is a simple command that can be used to display HTML from a given
file, or from the standard input, in an HtmlView. It replaces the `tho`
(test HTML output) command.
|
|
|
|
|
|
Fixes #407
Depends on #530 to run reliably.
|
|
An interactive application to modify the current display settings, such as
the current wallpaper as well as the screen resolution. Currently we're
adding the resolutions ourselves, because there's currently no way to
detect was resolutions the current display adapter supports (or at least
I can't see one... Maybe VBE does and I'm stupid). It even comes with
a very nice template'd `ItemList` that can support a vector of any type,
which makes life much simpler.
|
|
This can play anything that AWavLoader can load (so obviously only WAV
files at the moment.)
It works by having a timer that wakes up every 100ms and tries to send
a sample buffer to the AudioServer. If our server-side queue is full
then we wait until the next timer iteration and try again.
We display the most recently enqueued sample buffer in a nice little
widget that just plots the samples in green-on-black. :^)
|
|
Here comes the foundation for a neat remote debugging tool.
Right now, it connects to a remote process's CEventLoop RPC socket and
retreives the remote object graph JSON dump. The remote object graph
is then reconstructed and exposed through a GModel subclass, which is
then displayed in a GTreeView.
It's pretty cool, I think. :^)
|
|
It is now possible to unmount file systems from the VFS via `umount`.
It works via looking up the `fsid` of the filesystem from the `Inode`'s
metatdata so I'm not sure how fragile it is. It seems to work for now
though as something to get us going.
|
|
This is a more appropriate name now that it does a lot
more than just manage processes ^)
|
|
This should probably call out to a login program at some point. Right now
it just puts a root terminal on tty{1,2,3}.
Remember not to leave your Serenity workstation unattended!
|
|
This is to prepare for other framebuffer implementations, for which it
would be inappropriate to use the /dev/bxvga device name.
|
|
Closes https://github.com/SerenityOS/serenity/issues/319
|
|
Since they are nice enough to provide a JSON API over HTTP, this makes
for a perfect way to exercise our networking code a bit. :^)
|
|
Now that we can mount additional hard drives, let's actually have some
more device files in /dev so you can use them. :^)
|
|
Currently this will be used by the WindowServer to show some dialogs.
This is needed since WindowServer can't use LibGUI and reimplementing
message box functionality inside WindowServer would be silly. :^)
The only dialog supported in this initial version is --shutdown
|
|
The idea here is to implement a simple synhesizer that allows you to play
music with your keyboard. :^)
It's a huge hack currently but we can improve upon this.
|
|
Also add an AudioServer that (right now) doesn't do much.
It tries to open, parse, and play a wav file. In the future, it can do more.
My general thinking here here is that /dev/audio will be "owned" by AudioServer,
and we'll do mixing in software before passing buffers off to the kernel
to play, but we have to start somewhere.
|
|
This is a simple test app with its UI generated from a VisualBuilder form.
The name is probably silly, but who cares. :^)
|
|
Things were getting a little crowded in the project root, so this patch
moves the Lib*/ directories into Libraries/.
|
|
Userland/qs was moved to Applications/QuickShow, but some people still have
old built binaries lying around in their Userland/ directories and the build
system complains about this. Here goes a silly temporary hack to just get
rid of them.
|
|
This needs more work and polish, but it's a step in a more pleasant and
useful direction.
Also turn QuickShow into a fully-fledged "application". (By that, I really
just mean giving it its own Applications/ subdirectory.)
|
|
I'd like to have rich text, and we might as well use HTML for that. :^)
