Bananymous 446220494e Kernel: Unix domain sockets close can now be detected
When a unix domain socket is closed and it has a connection to another
socket, it will make the other socket readable and recv will return 0.

This allows detection of socket closing

Bananymous 84b3289a2a Kernel: Move Scheduler::yield() lock check after interrupts disabled
I have no idea why this solves a bug where current processor has
scheduler lock at the beginning of yield.

Bananymous 076f1efecb Kernel: Fix 32 bit fast page locking
I forgot to change this when changing the lock type. 32 bit boots again
fine :D

Bananymous b23511edb1 LibC: Don't use BAN inside pwd.cpp
This made pwd.cpp require libstdc++ which meant that getlogin() also
needed libstdc++. This made build process of libstdc++ require itself
which is of course not possible.

Bananymous 53e572f072 Kernel: Fix s_fast_page_lock type on 32 bit target 2024-05-29 18:04:23 +03:00
Bananymous c2b6ba0d5a Userspace: Start work on GUI and WindowServer
Current implementation can create custom windows and each window has
its own framebuffer. When window wants to write its framebuffer to the
screen it will send a message to the WindowServer using unix sockets.

Bananymous d4d530e6c8 Kernel: Implement basic shared memory objects
These can allocate memory that can be shared between processes using
a global key. There is currenly no safety checks meaning anyone can
map any shared memory object just by trying to map every possible key.

Bananymous 87d52e5ebe Kernel: Fix timer early wake message
When printing early return message, current time was read twice. This
could lead to early return check failing, but when printing and reading
the time again subtraction overflow would happen.

Bananymous a1ab44d39f Kernel: Optimize disk reads to read multiple sectors at once
Old StorageDevice::read_sectors() read each sector separately if the
underlying disk had a disk cache. This patch allows multiple sectors to
be read even if the disk cache exists and contains some of the sectors.

Only sectors that could not be found from the disk cache are actually
read from the disk. This optimization is not done for writing, which
still will write each sector separately, if disk cache has no memory to
store new sectors. It would feel kind of unnecessary optimization as you
have greater problems if disk cache cannot allocate a single page.

Bananymous 8b1514e575 Kernel: Make all storage devices readable and writable
I only had a {read,write}_impl defined for ATABaseDevice. This patch
moves that implmentation to general storage device.

Bananymous 2d3810874d Kernel: Fix thread signal handling
Threads will now only handle signals once they are not holding any
mutexes. This removes some dead locks.

Bananymous 2a4d986da5 Kernel: Add preliminary support for PCIe
Only segment 0 is supported, but devices can now be accessed through
mmio.

Adding more segments would require adding argument to every PCI API so
it is left for later.

Bananymous 3b18730af6 BuildSystem: Don't build libstdc++ as libc is not complete enough 2024-05-25 19:17:13 +03:00
Bananymous df260fe0e8 Kernel: Process::validate_pointer_access now maps the whole range
This fixes a bug where userspace provided address is not fully mapped
and the kernel tries to read/write it while using PageTable fast page.

In the future userspace input should be copied on syscall entry, so
userspace could not modify the input during syscall. Currently there
is change that userspace input passes kernel syscall validation and
after that userspace could modify the input before the value is
actually used.

Bananymous 2be4fe8404 Kernel: Make PageTable::s_fast_page_lock non-recursive
This lock is only used in wrapper of PageTable. There is no possiblity
of taking the lock outside of these wrappers.
