Summary
In the Linux kernel, the following vulnerability has been resolved:
RDMA/core: Fix FRMR aging push to queue error flow
Aging pools with pinned handles requires moving handles from the
active queue to a non-empty inactive queue that might fail on new page
allocation, we are currently not handling the fault and leaking any mkey
that fails the push.
Fix by Introducing push_queue_to_queue_locked() that fills the
destination's partial tail page from the source and then splices the
remaining source pages onto the destination, performing no allocation.
Replace the per-handle move loop in age_pinned_pool() and the
open-coded splice in pool_aging_work() with calls to the helper.
As the helper cannot fail under memory pressure, removing a class of
GFP_ATOMIC allocations under the pool lock and simplifying the error
flow.
