security: Fix security_old_inode_init_security() when CONFIG_SECURITY is not set
Commit 1e39f384bb01 ("evm: fix build problems") makes the stub version of security_old_inode_init_security() return 0 when CONFIG_SECURITY is not set. But that makes callers such as reiserfs_security_init() assume that security_old_inode_init_security() has set name, value, and len arguments properly - but security_old_inode_init_security() left them uninitialized which then results in interesting failures. Revert security_old_inode_init_security() to the old behavior of returning EOPNOTSUPP since both callers (reiserfs and ocfs2) handle this just fine. [ Also fixed the S_PRIVATE(inode) case of the actual non-stub security_old_inode_init_security() function to return EOPNOTSUPP for the same reason, as pointed out by Mimi Zohar. It got incorrectly changed to match the new function in commit fb88c2b6cbb1: "evm: fix security/security_old_init_security return code". - Linus ] Reported-by: Jorge Bastos <mysql.jorge@decimal.pt> Acked-by: James Morris <jmorris@namei.org> Acked-by: Mimi Zohar <zohar@us.ibm.com> Signed-off-by: Jan Kara <jack@suse.cz> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
