Summary
RDMA/erdma: Use IRQ-safe XArray helpers for QP and CQ tables
Details

In the Linux kernel, the following vulnerability has been resolved:

RDMA/erdma: Use IRQ-safe XArray helpers for QP and CQ tables

Locked QP and CQ lookups from EQ interrupts can deadlock with create-path XArray updates. If an interrupt arrives while the create path holds the plain xa_lock, the lookup spins forever trying to acquire the same lock.

Use IRQ-safe XArray helpers for all QP and CQ create-path updates, including the GSI QP store and error paths. Initialize both arrays with XA_FLAGS_LOCK_IRQ so sleeping allocations preserve interrupt state.
