[PATCH] security: use default hook return value in call_int_hook()

Ondrej Mosnacek omosnace at redhat.com
Tue Jan 30 12:56:59 UTC 2024


Change the definition of call_int_hook() to treat LSM_RET_DEFAULT(...)
as the "continue" value instead of 0. To further simplify this macro,
also drop the IRC argument and replace it with LSM_RET_DEFAULT(...).

After this the macro can be used in a couple more hooks, where similar
logic is currently open-coded. At the same time, some other existing
call_int_hook() users now need to be open-coded, but overall it's still
a net simplification.

There should be no functional change resulting from this patch.
