Add KDGETMODE and KDSETMODE ioctl support
...
Add support for virtual console TTY mode management ioctls required by
Xorg and other display servers. The implementation includes:
- KDGETMODE: Query the current virtual console mode
- KDSETMODE: Switch between text and graphics modes
Virtual consoles utilize the framebuffer with two distinct modes:
- Text mode (default): Kernel renders text characters to framebuffer
- Graphics mode: User space applications gain full framebuffer control
Xorg requires KDSETMODE during initialization to switch to graphics
mode, preventing conflicts where both the kernel and Xorg would
simultaneously attempt to write to the framebuffer. This ensures
proper display handling and eliminates rendering artifacts.

Correct /dev/tty1 major number to 4
...
The major number for /dev/tty1 must be 4, as this value is hardcoded
in Linux and Linux syscall-compatible operating systems. Xorg uses
this major number directly, and incorrect values lead to confusion
and operational failures.
This change ensures compatibility with Xorg's expectations and
maintains system consistency.

Implement `IdSet::iter_in`
...
This patch enables more expressive ways to slice and iterate over
the `Id`s in an `IdSet` with `IdSet::iter_in`, which takes an arbitrary
`IdSetSlicer`.
`IdSet::iter_in` efficiently slices out unintended inner parts and
then, within the remaining parts, skips inactive bits by using
`BitSlice::iter_ones` from the `bitvec` crate.
It also delivers several implementations of `IdSetSlicer` so OSTD
consumers can represent `Id` ranges ergonomically.
In the Asterinas kernel, `CpuSet::iter_in` enables a cleaner way to
define an interator that cycles over the CPUs.

Enhanced per-CPU load stats
...
This patch creates a `PerCpuLoadStats` with slightly enhanced, enough
to serve load stats and the load-balancing algorithm. This struct can
be further enhanced for more elaborated load-balancing algorithms in
the future.
The load stats report has been fixed, as `SchedulerStats::nr_queued_and_running`
no longer includes idle threads in the queued total nor in the running
threads.
Furthemore, the load-balancing algorithm has been improved because it
no longer accounts with the idle threads when they're enqueued.

`context.rs` enhancements
...
* Improve the phrasing of some docstrings and comments
* Add warning comments about attempts to validate memory addresses
at reader/writer instantiation time
* Create the `reader_writer` method for ergonomically instantiate
a reader/writer pair covering the same memory region. This method
is also slightly more efficient than calling `reader` and `writer`
separately
* Clean up `check_vaddr` for clarity and rename it to `check_vaddr_lowerbound`
for explicity
* Include the data length check before calling `check_vaddr_lowerbound`
in `atomic_load` and `atomic_fetch_update` for further consistency
with the delayed buffer validation

Patch a futex vulnerability
...
If the futex wait operation was interrupted by a signal or timed out, the
`FutexItem` must be dequeued and dropped. Otherwise, malicious user programs
could repeatedly issue futex wait operations to exhaust kernel memory.
Due to asynchronicity, this removal can't be done by queue position nor by
futex key match up:
* The position might have changed during the pause as some earlier futex might
have been dequeued
* If two futexes with the same key are enqueued and then one of them times out
or is interrupted, a removal by key would likely dequeue the wrong futex
Therefore, we need to perform a removal by unique global futex ID.

Then use `atomic_compare_exchange` to reimplement the looping logic
of `wake_robust_futex` and make it atomic.

chore: use `jhash` to compute the `FutexKey` hash
...
This patch pays the price of making the instantiation of `FutexKey`
more expensive to achieve two goals:
* Minor: make `match_up` slightly faster
* Major: make futex bucket allocation balancing more robust
2025-08-16 09:16:50 +08:00
91351e338f
fix: avoid distribution skew in `FutexBucketVec::get_bucket`
...
Doing `addr / self.size()` before masking with `(self.size() - 1)`
removes the low bits entirely, which causes adjacent addresses
(modulo `self.size()`) to map to the same bucket, entailing bad
load balance. This patch solves that.
Further, make `FutexBucketVec::new` and `FutexBucketVec::get_bucket`
private, as they only make sense within the scope of `futex.rs`,
where the invariant of `size` being a power of two is guaranteed to
hold via `get_bucket_count` (which is also private).

chore: avoid several `FutexKey` copies

Disallow masking SIGKILL and SIGSTOP in user space
...
According to the Linux man pages[1], "It is not possible to block SIGKILL
or SIGSTOP. Attempts to do so are silently ignored." This patch ensures
compliance by explicitly removing SIGKILL and SIGSTOP from the signal
mask in the `MaskOp::SetMask` operation of the `rt_sigprocmask` syscall.
