Pull audit updates from Paul Moore: "Four small audit patches for v4.2, all bug fixes. Only 10 lines of change this time so very unremarkable, the patch subject lines pretty much tell the whole story" * 'upstream' of git://git.infradead.org/users/pcmoore/audit: audit: Fix check of return value of strnlen_user() audit: obsolete audit_context check is removed in audit_filter_rules() audit: fix for typo in comment to function audit_log_link_denied() lsm: rename duplicate labels in LSM_AUDIT_DATA_TASK audit message type

lsm: rename duplicate labels in LSM_AUDIT_DATA_TASK audit message type

2015-05-29T19:09:54+00:00

The LSM_AUDIT_DATA_TASK pid= and comm= labels are duplicates of those at the start of this function with different values. Rename them to their object counterparts opid= and ocomm= to disambiguate.

lsm: copy comm before calling audit_log to avoid race in string printing

2015-04-15T00:13:20+00:00

When task->comm is passed directly to audit_log_untrustedstring() without getting a copy or using the task_lock, there is a race that could happen that would output a NULL (\0) in the middle of the output string that would effectively truncate the rest of the report text after the comm= field in the audit log message, losing fields. Using get_task_comm() to get a copy while acquiring the task_lock to prevent this and to prevent the result from being a mixture of old and new values of comm would incur potentially unacceptable overhead, considering that the value can be influenced by userspace and therefore untrusted anyways. Copy the value before passing it to audit_log_untrustedstring() ensures that a local copy is used to calculate the length *and* subsequently printed. Even if this value contains a mix of old and new values, it will only calculate and copy up to the first NULL, preventing the rest of the audit log message being truncated. Use a second local copy of comm to avoid a race between the first and second calls to audit_log_untrustedstring() with comm.
