/* Maximum number of letters for an LSM name string */
* @old_path contains the path for the new location of the current root (put_old).
* @new_path contains the path for the new root (new_root).
* Return 0 if permission is granted.
- * @sb_post_pivotroot:
- * Update module state after a successful pivot.
- * @old_path contains the path for the old root.
- * @new_path contains the path for the new root.
* @sb_set_mnt_opts:
* Set the security relevant mount options used for a superblock
* @sb the superblock to set security mount options for
* @mnt is the vfsmount where the dentry was looked up
* @dentry contains the dentry structure for the file.
* Return 0 if permission is granted.
- * @inode_delete:
- * @inode contains the inode structure for deleted inode.
- * This hook is called when a deleted inode is released (i.e. an inode
- * with no hard links has its use count drop to zero). A security module
- * can use this hook to release any persistent label associated with the
- * inode.
* @inode_setxattr:
* Check permission before setting the extended attributes
* @value identified by @name for @dentry.
* @old points to the original credentials.
* @gfp indicates the atomicity of any memory allocations.
* Prepare a new set of credentials by copying the data from the old set.
- * @cred_commit:
- * @new points to the new credentials.
- * @old points to the original credentials.
- * Install a new set of credentials.
* @cred_transfer:
* @new points to the new credentials.
* @old points to the original credentials.
* userspace to load a kernel module with the given name.
* @kmod_name name of the module requested by the kernel
* Return 0 if successful.
- * @task_setuid:
- * Check permission before setting one or more of the user identity
- * attributes of the current process. The @flags parameter indicates
- * which of the set*uid system calls invoked this hook and how to
- * interpret the @id0, @id1, and @id2 parameters. See the LSM_SETID
- * definitions at the beginning of this file for the @flags values and
- * their meanings.
- * @id0 contains a uid.
- * @id1 contains a uid.
- * @id2 contains a uid.
- * @flags contains one of the LSM_SETID_* values.
- * Return 0 if permission is granted.
* @task_fix_setuid:
* Update the module's state after setting one or more of the user
* identity attributes of the current process. The @flags parameter
* @old is the set of credentials that are being replaces
* @flags contains one of the LSM_SETID_* values.
* Return 0 on success.
- * @task_setgid:
- * Check permission before setting one or more of the group identity
- * attributes of the current process. The @flags parameter indicates
- * which of the set*gid system calls invoked this hook and how to
- * interpret the @id0, @id1, and @id2 parameters. See the LSM_SETID
- * definitions at the beginning of this file for the @flags values and
- * their meanings.
- * @id0 contains a gid.
- * @id1 contains a gid.
- * @id2 contains a gid.
- * @flags contains one of the LSM_SETID_* values.
- * Return 0 if permission is granted.
* @task_setpgid:
* Check permission before setting the process group identifier of the
* process @p to @pgid.
* @p contains the task_struct for the process and place is into @secid.
* In case of failure, @secid will be set to zero.
*
- * @task_setgroups:
- * Check permission before setting the supplementary group set of the
- * current process.
- * @group_info contains the new group information.
- * Return 0 if permission is granted.
* @task_setnice:
* Check permission before setting the nice value of @p to @nice.
* @p contains the task_struct of process.
* Return the length of the string (including terminating NUL) or -ve if
* an error.
* May also return 0 (and a NULL buffer pointer) if there is no label.
- * @key_session_to_parent:
- * Forcibly assign the session keyring from a process to its parent
- * process.
- * @cred: Pointer to process's credentials
- * @parent_cred: Pointer to parent process's credentials
- * @keyring: Proposed new session keyring
- * Return 0 if permission is granted, -ve error otherwise.
*
* Security hooks affecting all System V IPC operations.
*
* @cap contains the capability <include/linux/capability.h>.
* @audit: Whether to write an audit message or not
* Return 0 if the capability is granted for @tsk.
- * @acct:
- * Check permission before enabling or disabling process accounting. If
- * accounting is being enabled, then @file refers to the open file used to
- * store accounting records. If accounting is being disabled, then @file
- * is NULL.
- * @file contains the file structure for the accounting file (may be NULL).
- * Return 0 if permission is granted.
* @sysctl:
* Check permission before accessing the @table sysctl variable in the
* manner specified by @op.
