[PATCH V33 27/30] lockdown: Print current->comm in restriction messages

From: Matthew Garrett <hidden>
Date: 2019-06-21 01:21:08
Also in: lkml
Subsystem: lockdown security module, security subsystem, the rest · Maintainers: Nicolas Bouchinet, Xiu Jianfeng, Paul Moore, James Morris, "Serge E. Hallyn", Linus Torvalds

Print the content of current->comm in messages generated by lockdown to
indicate a restriction that was hit.  This makes it a bit easier to find
out what caused the message.

The message now patterned something like:

        Lockdown: <comm>: <what> is restricted; see man kernel_lockdown.7
