Use const parameters where applicable to signal immutability. Rename the passed iterator avrule from avrule to narule, to make clear its the neverallow rule to assert against, not the allow rule to check. Drop needless branch in check_assertions(), since in the case avrules is NULL the for loop won't execute and errors will stay at 0, so 0 will be returned regardless. Also there is no call to free() as mentioned in the outdated comment. Signed-off-by: Christian Göttsche <[email protected]> --- v3: - use C99 bool where applicable - minor additions v2: add patch
Add support for extended permission rules in conditional policies by adding a new policy version and adjusting writing and validating policies accordingly. Signed-off-by: Christian Göttsche <[email protected]> --- v5: - reintroduce correct avrule checking for conditional policies regressed in v4 via deduplication v4: - fix assertion logic on CIL generated policy - enhance xperm validation - rebase onto main v3: - several assertion logic fixes v2: - rebase onto libsepol: Support nlmsg xperms in assertions - fix assertion checking with xperm av rules in conditional policies (spotted by Jim, thanks!)
