tty: audit: move some local functions out of tty.h

2021-04-15T08:24:58+00:00

The functions tty_audit_add_data() and tty_audit_tiocsti() are local to the tty core code, and do not need to be in a "kernel-wide" header file so move them to drivers/tty/tty.h Cc: Jiri Slaby Link: https://lore.kernel.org/r/20210408125134.3016837-9-gregkh@linuxfoundation.org Signed-off-by: Greg Kroah-Hartman

tty: tty_audit: Demote non-conformant kernel-doc headers

audit: join tty records to their syscall

2019-02-08T02:33:54+00:00

AUDIT_TTY records were logged as seperate events from their syscall records. Join them so they are logged as the single event that they are. Please see the github issue https://github.com/linux-audit/audit-kernel/issues/106 Signed-off-by: Richard Guy Briggs Signed-off-by: Paul Moore

audit: use current whenever possible

2018-11-26T23:41:21+00:00

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: eliminate audit_enabled magic number comparison

2018-06-19T14:43:55+00:00

Remove comparison of audit_enabled to magic numbers outside of audit. Related: https://github.com/linux-audit/audit-kernel/issues/86 Signed-off-by: Richard Guy Briggs Signed-off-by: Paul Moore

tty: Remove redundant license text

2017-11-08T12:08:12+00:00

Now that the SPDX tag is in all tty files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.

tty: add SPDX identifiers to all remaining files in drivers/tty/

2017-11-08T12:08:12+00:00

It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/tty files files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

tty: audit: remove unused variable

2016-03-08T00:11:14+00:00

While building with W=1 we were getting build warning: drivers/tty/tty_audit.c:149:16: warning: variable 'sessionid' set but not used The local variable sessionid was only assigned the value of current->sessionid but was never reused. On further inspection it turned out that there is no need of audit_get_loginuid() also. Signed-off-by: Sudip Mukherjee Reviewed-by: Peter Hurley Signed-off-by: Greg Kroah-Hartman
