Subject: [PATCH] python/sepolgen: allow any policy statement in if(n)def
|
|
|
d6d821 |
|
|
|
d6d821 |
"ifdef/ifndef" statements can be used to conditionally define
|
|
|
d6d821 |
an interface, but this syntax is not recognised by sepolgen-ifgen.
|
|
|
d6d821 |
Fix sepolgen-ifgen to allow any policy statement inside an
|
|
|
d6d821 |
"ifdef/ifndef" statement.
|
|
|
d6d821 |
|
|
|

Fixes:
|
|
