[PATCH 0/4] lockd refcount conversions

From: Elena Reshetova
Date: Wed Nov 29 2017 - 06:15:59 EST


This series, for lockd component, replaces atomic_t reference
counters with the new refcount_t type and API (see include/linux/refcount.h).
By doing this we prevent intentional or accidental
underflows or overflows that can led to use-after-free vulnerabilities.

The patches are fully independent and can be cherry-picked separately.
If there are no objections to the patches, please merge them via respective tree.

Elena Reshetova (4):
lockd: convert nlm_host.h_count from atomic_t to refcount_t
lockd: convert nsm_handle.sm_count from atomic_t to refcount_t
lockd: convert nlm_lockowner.count from atomic_t to refcount_t
lockd: convert nlm_rqst.a_count from atomic_t to refcount_t
