Subject: [PATCH 00/12] fs, nfs conversions from atomic_t to refcount_t
Date: Tue, 14 Mar 2017 09:07:08 +0200 [thread overview]
Message-ID: <1489475240-6594-1-git-send-email-elena.reshetova@intel.com> (raw)
This series, for nfs filesystem, 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 below patches have been run-time tested using NFStest on the client side only.
No issues related to refcounter conversions were detected.
If you don't see objections or issues with the patches, please take it to
your tree.
Elena Reshetova (12):
fs, nfsd: convert nfs4_stid.sc_count from atomic_t to refcount_t
fs, nfsd: convert nfs4_cntl_odstate.co_odcount from atomic_t to
