ILOOKUP5(9) The Linux VFS ILOOKUP5(9)NAME
ilookup5 - search for an inode in the inode cache
SYNOPSIS
struct inode * ilookup5(struct super_block * sb, unsigned long hashval, int (*test) (struct inode *, void *), void * data);
ARGUMENTS
sb
super block of file system to search
hashval
hash value (usually inode number) to search for
test
callback used for comparisons between inodes
data
opaque data pointer to pass to test
DESCRIPTION
Search for the inode specified by hashval and data in the inode cache, and if the inode is in the cache, return the inode with an
incremented reference count. Waits on I_NEW before returning the inode. returned with an incremented reference count.
This is a generalized version of ilookup for file systems where the inode number is not sufficient for unique identification of an inode.
NOTE
test is called with the inode_hash_lock held, so can't sleep.

matchpathcon_checkmatches(3) SELinux API documentation matchpathcon_checkmatches(3)NAME
matchpathcon_checkmatches, matchpathcon_filespec_add, matchpathcon_filespec_destroy, matchpathcon_filespec_eval - check and report whether
any specification index has no matches with any inode. Maintenance and statistics on inode associations.
SYNOPSIS
#include <selinux/selinux.h>
void matchpathcon_checkmatches(char *str);
int matchpathcon_filespec_add(ino_t ino, int specind, const char *file);
void matchpathcon_filespec_destroy(void);
void matchpathcon_filespec_eval(void);
DESCRIPTION
matchpathcon_checkmatches checks whether any specification has no matches and reports them. The str argument is used as a prefix for any
warning messages.
matchpathcon_filespec_add maintains an association between an inode ino and a specification index specind, and checks whether a conflicting
specification is already associated with the same inode (e.g. due to multiple hard links). If so, then it uses the latter of the two speci-
fications based on their order in the file context configuration. Returns the specification index used or -1 on error.
matchpathcon_filespec_destroy destroys any inode associations that have been added, e.g. to restart for a new filesystem.
matchpathcon_filespec_eval displays statistics on the hash table usage for the inode associations.
RETURN VALUE
Returns zero on success or -1 otherwise.
