Thanks for the update. I have 2 more things for you to consider. a. In multiple places, there is something like "return 0 when no error and return a negative error code otherwise." I would say "or return a negative error code otherwise." b. (below)
===========================
FILESYSTEM CONTEXT SECURITY
===========================
The filesystem context contains a security pointer that the LSMs can use for
building up a security context for the superblock to be mounted. There are a
number of operations used by the new mount code for this purpose:
(*) int security_fs_context_alloc(struct fs_context *fc,
struct super_block *src_sb);
Called to initialise fc->security (which is preset to NULL) and allocate
any resources needed. It should return 0 on success and a negative error
code on failure.
src_sb is non-NULL in the case of a remount (FS_CONTEXT_FOR_REMOUNT) in
which case it indicates the superblock to be remounted or in the case of a
submount (FS_CONTEXT_FOR_SUBMOUNT) in which case it indicates the parent
superblock.-ETOOMANYCASES Maybe: For a remount (FS_CONTEXT_FOR_REMOUNT), src_sb is non-NULL and indicates the superblock to be remounted. For a submount (FS_CONTEXT_FOR_SUBMOUNT), src_sb is also non-NULL and represents the parent superblock. cheers. -- ~Randy -- To unsubscribe from this list: send the line "unsubscribe linux-security-module" in the body of a message to majordomo at vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
