Subject: [PATCH 0/5] fs, xfs refcount conversions
Date: Wed, 8 Mar 2017 10:53:34 +0200 [thread overview]
Message-ID: <1488963219-11709-1-git-send-email-elena.reshetova@intel.com> (raw)
v3:
* fixed header file inclusion
Now when new refcount_t type and API are finally merged
(see include/linux/refcount.h), the following
patches convert various refcounters in the xfs susystem from atomic_t
to refcount_t. By doing this we prevent intentional or accidental
underflows or overflows that can led to use-after-free vulnerabilities.
Elena Reshetova (5):
fs, xfs: convert xfs_bui_log_item.bui_refcount from atomic_t to
refcount_t
fs, xfs: convert xfs_efi_log_item.efi_refcount from atomic_t to
refcount_t
fs, xfs: convert xlog_ticket.t_ref from atomic_t to refcount_t
fs, xfs: convert xfs_cui_log_item.cui_refcount from atomic_t to
refcount_t
fs, xfs: convert xfs_rui_log_item.rui_refcount from atomic_t to
refcount_t
