Kernel/Graphics: Introduce the DisplayConnector class The DisplayConnector class is meant to replace the FramebufferDevice class. The advantage of this class over the FramebufferDevice class is: 1. It removes the mmap interface entirely. This interface is unsafe, as multiple processes could try to use it, and when switching to and from text console mode, there's no "good" way to revoke a memory mapping from this interface, let alone when there are multiple processes that call this interface. Therefore, in the DisplayConnector class there's no implementation for this method at all. 2. The class uses a new real-world structure called ModeSetting, which takes into account the fact that real hardware requires more than width, height and pitch settings to mode-set the display resolution. 3. The class assumes all instances should supply some sort of EDID, so it facilitates such mechanism to do so. Even if a given driver does not know what is the actual EDID, it will ask to create default-generic EDID blob. 3. This class shifts the responsibilies of switching between console mode and graphical mode from a GraphicsAdapter to the DisplayConnector class, so when doing the switch, the GraphicsManagement code actually asks each DisplayConnector object to do the switch and doesn't rely on the GraphicsAdapter objects at all.

The most important consequence of rearranging the classes is that we now have one IOCTL method, so all drivers should be committed to not override the IOCTL method or make their own IOCTLs of FramebufferDevice. All graphical IOCTLs are known to all FramebufferDevices, and it's up to the specific implementation whether to support them or discard them (so we require extensive usage of KResult and KResultOr, together with virtual characteristic functions). As a result, the interface is much cleaner and understandable to read.

Kernel+Userland: Add ioctl to set process ownership of DisplayConnector Now that the infrastructure of the Graphics subsystem is quite stable, it is time to try to fix a long-standing problem, which is the lack of locking on display connector devices. Reading and writing from multiple processes to a framebuffer controlled by the display connector is not a huge problem - it could be solved with POSIX locking. The real problem is some program that will try to do ioctl operations on a display connector without the WindowServer being aware of that which can lead to very bad situations, for example - assuming a framebuffer is encoded at a known resolution and certain display timings, but another process changed the ModeSetting of the display connector, leading to inconsistency on the properties of the current ModeSetting. To solve this, there's a new "master" ioctl to take "ownership" and another one to release that ownership of a display connector device. To ensure we will not hold a Process object forever just because it has an ownership over a display connector, we hold it with a weak reference, and if the process is gone, someone else can take an ownership.

Kernel+LibCore+LibC: Split the mount syscall into multiple syscalls This is a preparation before we can create a usable mechanism to use filesystem-specific mount flags. To keep some compatibility with userland code, LibC and LibCore mount functions are kept being usable, but now instead of doing an "atomic" syscall, they do multiple syscalls to perform the complete procedure of mounting a filesystem. The FileBackedFileSystem IntrusiveList in the VFS code is now changed to be protected by a Mutex, because when we mount a new filesystem, we need to check if a filesystem is already created for a given source_fd so we do a scan for that OpenFileDescription in that list. If we fail to find an already-created filesystem we create a new one and register it in the list if we successfully mounted it. We use a Mutex because we might need to initiate disk access during the filesystem creation, which will take other mutexes in other parts of the kernel, therefore making it not possible to take a spinlock while doing this.

This function has to be defined by us. By noting down the caller in that function we can trace the code we have encountered during execution. Such information is used by coverage guided fuzzers like AFL and LibFuzzer to determine if a new input resulted in a new code path. This makes fuzzing much more effective. Additionally this adds a basic KCOV implementation. KCOV is an API that allows user space to request the kernel to start collecting coverage information for a given user space thread. Furthermore KCOV then exposes the collected program counters to user space via a BlockDevice which can be mmaped from user space. This work is required to add effective support for fuzzing SerenityOS to the Syzkaller syscall fuzzer. :^) :^)

The static construction method is given an OpenFileDescription reference but validates that: - The description has a valid custody (so it's not some arbitrary file). Failing this requirement will yield EINVAL. - The description custody points to an Inode which is a regular file, as we only support (seekable) regular files. Failing this requirement will yield ENOTSUP. LoopDevice can be used to mount a regular file on the filesystem like other supported types of (physical) block devices.

Kernel+Userland: Add ioctl to set process ownership of DisplayConnector Now that the infrastructure of the Graphics subsystem is quite stable, it is time to try to fix a long-standing problem, which is the lack of locking on display connector devices. Reading and writing from multiple processes to a framebuffer controlled by the display connector is not a huge problem - it could be solved with POSIX locking. The real problem is some program that will try to do ioctl operations on a display connector without the WindowServer being aware of that which can lead to very bad situations, for example - assuming a framebuffer is encoded at a known resolution and certain display timings, but another process changed the ModeSetting of the display connector, leading to inconsistency on the properties of the current ModeSetting. To solve this, there's a new "master" ioctl to take "ownership" and another one to release that ownership of a display connector device. To ensure we will not hold a Process object forever just because it has an ownership over a display connector, we hold it with a weak reference, and if the process is gone, someone else can take an ownership.

Kernel+LibCore+LibC: Split the mount syscall into multiple syscalls This is a preparation before we can create a usable mechanism to use filesystem-specific mount flags. To keep some compatibility with userland code, LibC and LibCore mount functions are kept being usable, but now instead of doing an "atomic" syscall, they do multiple syscalls to perform the complete procedure of mounting a filesystem. The FileBackedFileSystem IntrusiveList in the VFS code is now changed to be protected by a Mutex, because when we mount a new filesystem, we need to check if a filesystem is already created for a given source_fd so we do a scan for that OpenFileDescription in that list. If we fail to find an already-created filesystem we create a new one and register it in the list if we successfully mounted it. We use a Mutex because we might need to initiate disk access during the filesystem creation, which will take other mutexes in other parts of the kernel, therefore making it not possible to take a spinlock while doing this.

The SB16 device keeps track of the sample rate separately, because I don't want to figure out how to read the sample rate from the device; it's easier that way. The soundcard write doesn't set the sample rate to 44100 Hz every time anymore, as we want to change it externally.

Kernel/Devices: Introduce the LoopDevice device This device is a block device that allows a user to effectively treat an Inode as a block device. The static construction method is given an OpenFileDescription reference but validates that: - The description has a valid custody (so it's not some arbitrary file). Failing this requirement will yield EINVAL. - The description custody points to an Inode which is a regular file, as we only support (seekable) regular files. Failing this requirement will yield ENOTSUP. LoopDevice can be used to mount a regular file on the filesystem like other supported types of (physical) block devices.
