2023-09-19bcachefs-tools: fix endian problems between bit spinlocks and futexesBrian Foster
bcachefs format on a big-endian (s390x) machine crashes down in the rhashtable code imported from the kernel. The reason this occurs lies within the rht_lock() -> bit_spin_lock() code, the latter of which casts bitmaps down to 32-bits to satisfy the requirements of the futex interface. The specific problem here is that a 64 -> 32 bit cast doesn't refer to the lower 8 bytes on a big endian machine, which means setting bit number 0 in the 32-bit map actually corresponds to bit 32 in the 64-bit map. The rhashtable code specifically uses bit zero of the bucket pointer for exclusion and uses native bitops elsewhere (i.e. __rht_ptr()) to identify NULL pointers. If bit 32 of the pointer is set by the locking code instead of bit 0, an otherwise NULL pointer looks like a non-NULL value and results in a segfault. The bit spinlock code imported by the kernel is originally intended to work with unsigned long. The kernel code is able to throttle the cpu directly when under lock contention, while the userspace implementation relies on the futex primitives to emulate reliable blocking. Since the futex interface introduces the 32-bit requirement, isolate the associated userspace hack to that particular code. Restore the native bitmap behavior of the bit spinlock code to address the rhashtable problem described above. Since this is not compatible with the futex interface, create a futex wrapper specifically to convert the native bitmap type to a 32-bit virtual address and mask value for the purposes of waiting/waking when under lock contention.

2022-10-11Don't run shrinkers without GFP_KERNELKent Overstreet
This would correspond to GFP_RECLAIM in the kernel - but we don't distinguish between different types of reclaim here. This solves a deadlock in the btree node memory allocation path - we allocate with the btree node cache lock held but without GFP_KERNEL set.
