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.

chore: use `jhash` to compute the `FutexKey` hash
...
This patch pays the price of making the instantiation of `FutexKey`

* 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).
