audit: use current whenever possible

2018-11-26T23:41:21Z

There are many places, notably audit_log_task_info() and audit_log_exit(), that take task_struct pointers but in reality they are always working on the current task. This patch eliminates the task_struct arguments and uses current directly which allows a number of cleanups as well. Acked-by: Richard Guy Briggs Signed-off-by: Paul Moore

audit: remove WATCH and TREE config options

2018-11-19T21:29:50Z

Remove the CONFIG_AUDIT_WATCH and CONFIG_AUDIT_TREE config options since they are both dependent on CONFIG_AUDITSYSCALL and force CONFIG_FSNOTIFY. Signed-off-by: Richard Guy Briggs Signed-off-by: Paul Moore

audit: localize audit_log_session_info prototype

2018-11-19T17:26:27Z

The audit_log_session_info() function is only used in kernel/audit*, so move its prototype to kernel/audit.h Signed-off-by: Richard Guy Briggs Signed-off-by: Paul Moore

audit: track the owner of the command mutex ourselves

2018-02-23T16:22:22Z

Evidently the __mutex_owner() function was never intended for use outside the core mutex code, so build a thing locking wrapper around the mutex code which allows us to track the mutex owner. One, arguably positive, side effect is that this allows us to hide the audit_cmd_mutex inside of kernel/audit.c behind the lock/unlock functions.

audit: convert audit_ever_enabled to a boolean

We were treating it as a boolean, let's make it a boolean to help avoid future mistakes. Reviewed-by: Richard Guy Briggs Signed-off-by: Paul Moore

ipc: mqueue: Replace timespec with timespec64

2017-09-04T00:21:24Z

struct timespec is not y2038 safe. Replace all uses of timespec by y2038 safe struct timespec64. Even though timespec is used here to represent timeouts, replace these with timespec64 so that it facilitates in verification by creating a y2038 safe kernel image that is free of timespec. The syscall interfaces themselves are not changed as part of the patch. They will be part of a different series.

audit: add ambient capabilities to CAPSET and BPRM_FCAPS records

2017-05-30T21:36:11Z

Capabilities were augmented to include ambient capabilities in v4.3 commit 58319057b784 ("capabilities: ambient capabilities"). Add ambient capabilities to the audit BPRM_FCAPS and CAPSET records. The record contains fields "old_pp", "old_pi", "old_pe", "new_pp", "new_pi", "new_pe" so in keeping with the previous record normalizations, change the "new_*" variants to simply drop the "new_" prefix.

audit: Use timespec64 to represent audit timestamps

2017-05-02T14:16:05Z

struct timespec is not y2038 safe. Audit timestamps are recorded in string format into an audit buffer for a given context. These mark the entry timestamps for the syscalls. Use y2038 safe struct timespec64 to represent the times. The log strings can handle this transition as strings can hold upto 1024 characters.
