/**
|
|
* struct security_operations - main security structure
|
|
*
|
|
* Security hooks for program execution operations.
|
|
*
|
|
* @bprm_alloc_security:
|
|
* Allocate and attach a security structure to the @bprm->security field.
|
|
* The security field is initialized to NULL when the bprm structure is
|
|
* allocated.
|
|
* @bprm contains the linux_binprm structure to be modified.
|
|
* Return 0 if operation was successful.
|
|
* @bprm_free_security:
|
|
* @bprm contains the linux_binprm structure to be modified.
|
|
* Deallocate and clear the @bprm->security field.
|
|
* @bprm_apply_creds:
|
|
* Compute and set the security attributes of a process being transformed
|
|
* by an execve operation based on the old attributes (current->security)
|
|
* and the information saved in @bprm->security by the set_security hook.
|
|
* Since this hook function (and its caller) are void, this hook can not
|
|
* return an error. However, it can leave the security attributes of the
|
|
* process unchanged if an access failure occurs at this point.
|
|
* bprm_apply_creds is called under task_lock. @unsafe indicates various
|
|
* reasons why it may be unsafe to change security state.
|
|
* @bprm contains the linux_binprm structure.
|
|
* @bprm_post_apply_creds:
|
|
* Runs after bprm_apply_creds with the task_lock dropped, so that
|
|
* functions which cannot be called safely under the task_lock can
|
|
* be used. This hook is a good place to perform state changes on
|
|
* the process such as closing open file descriptors to which access
|
|
* is no longer granted if the attributes were changed.
|
|
* Note that a security module might need to save state between
|
|
* bprm_apply_creds and bprm_post_apply_creds to store the decision
|
|
* on whether the process may proceed.
|
|
* @bprm contains the linux_binprm structure.
|
|
* @bprm_set_security:
|
|
* Save security information in the bprm->security field, typically based
|
|
* on information about the bprm->file, for later use by the apply_creds
|
|
* hook. This hook may also optionally check permissions (e.g. for
|
|
* transitions between security domains).
|
|
* This hook may be called multiple times during a single execve, e.g. for
|
|
* interpreters. The hook can tell whether it has already been called by
|
|
* checking to see if @bprm->security is non-NULL. If so, then the hook
|
|
* may decide either to retain the security information saved earlier or
|
|
* to replace it.
|
|
* @bprm contains the linux_binprm structure.
|
|
* Return 0 if the hook is successful and permission is granted.
|
|
* @bprm_check_security:
|
|
* This hook mediates the point when a search for a binary handler will
|
|
* begin. It allows a check the @bprm->security value which is set in
|
|
* the preceding set_security call. The primary difference from
|
|
* set_security is that the argv list and envp list are reliably
|
|
* available in @bprm. This hook may be called multiple times
|
|
* during a single execve; and in each pass set_security is called
|
|
* first.
|
|
* @bprm contains the linux_binprm structure.
|
|
* Return 0 if the hook is successful and permission is granted.
|
|
* @bprm_secureexec:
|
|
* Return a boolean value (0 or 1) indicating whether a "secure exec"
|
|
* is required. The flag is passed in the auxiliary table
|
|
* on the initial stack to the ELF interpreter to indicate whether libc
|
|
* should enable secure mode.
|
|
* @bprm contains the linux_binprm structure.
|
|
*
|
|
* Security hooks for filesystem operations.
|
|
*
|
|
* @sb_alloc_security:
|
|
* Allocate and attach a security structure to the sb->s_security field.
|
|
* The s_security field is initialized to NULL when the structure is
|
|
* allocated.
|
|
* @sb contains the super_block structure to be modified.
|
|
* Return 0 if operation was successful.
|
|
* @sb_free_security:
|
|
* Deallocate and clear the sb->s_security field.
|
|
* @sb contains the super_block structure to be modified.
|
|
* @sb_statfs:
|
|
* Check permission before obtaining filesystem statistics for the @sb
|
|
* filesystem.
|
|
* @sb contains the super_block structure for the filesystem.
|
|
* Return 0 if permission is granted.
|
|
* @sb_mount:
|
|
* Check permission before an object specified by @dev_name is mounted on
|
|
* the mount point named by @nd. For an ordinary mount, @dev_name
|
|
* identifies a device if the file system type requires a device. For a
|
|
* remount (@flags & MS_REMOUNT), @dev_name is irrelevant. For a
|
|
* loopback/bind mount (@flags & MS_BIND), @dev_name identifies the
|
|
* pathname of the object being mounted.
|
|
* @dev_name contains the name for object being mounted.
|
|
* @nd contains the nameidata structure for mount point object.
|
|
* @type contains the filesystem type.
|
|
* @flags contains the mount flags.
|
|
* @data contains the filesystem-specific data.
|
|
* Return 0 if permission is granted.
|
|
* @sb_copy_data:
|
|
* Allow mount option data to be copied prior to parsing by the filesystem,
|
|
* so that the security module can extract security-specific mount
|
|
* options cleanly (a filesystem may modify the data e.g. with strsep()).
|
|
* This also allows the original mount data to be stripped of security-
|
|
* specific options to avoid having to make filesystems aware of them.
|
|
* @type the type of filesystem being mounted.
|
|
* @orig the original mount data copied from userspace.
|
|
* @copy copied data which will be passed to the security module.
|
|
* Returns 0 if the copy was successful.
|
|
* @sb_check_sb:
|
|
* Check permission before the device with superblock @mnt->sb is mounted
|
|
* on the mount point named by @nd.
|
|
* @mnt contains the vfsmount for device being mounted.
|
|
* @nd contains the nameidata object for the mount point.
|
|
* Return 0 if permission is granted.
|
|
* @sb_umount:
|
|
* Check permission before the @mnt file system is unmounted.
|
|
* @mnt contains the mounted file system.
|
|
* @flags contains the unmount flags, e.g. MNT_FORCE.
|
|
* Return 0 if permission is granted.
|
|
* @sb_umount_close:
|
|
* Close any files in the @mnt mounted filesystem that are held open by
|
|
* the security module. This hook is called during an umount operation
|
|
* prior to checking whether the filesystem is still busy.
|
|
* @mnt contains the mounted filesystem.
|
|
* @sb_umount_busy:
|
|
* Handle a failed umount of the @mnt mounted filesystem, e.g. re-opening
|
|
* any files that were closed by umount_close. This hook is called during
|
|
* an umount operation if the umount fails after a call to the
|
|
* umount_close hook.
|
|
* @mnt contains the mounted filesystem.
|
|
* @sb_post_remount:
|
|
* Update the security module's state when a filesystem is remounted.
|
|
* This hook is only called if the remount was successful.
|
|
* @mnt contains the mounted file system.
|
|
* @flags contains the new filesystem flags.
|
|
* @data contains the filesystem-specific data.
|
|
* @sb_post_mountroot:
|
|
* Update the security module's state when the root filesystem is mounted.
|
|
* This hook is only called if the mount was successful.
|
|
* @sb_post_addmount:
|
|
* Update the security module's state when a filesystem is mounted.
|
|
* This hook is called any time a mount is successfully grafetd to
|
|
* the tree.
|
|
* @mnt contains the mounted filesystem.
|
|
* @mountpoint_nd contains the nameidata structure for the mount point.
|
|
* @sb_pivotroot:
|
|
* Check permission before pivoting the root filesystem.
|
|
* @old_nd contains the nameidata structure for the new location of the current root (put_old).
|
|
* @new_nd contains the nameidata structure for the new root (new_root).
|
|
* Return 0 if permission is granted.
|
|
* @sb_post_pivotroot:
|
|
* Update module state after a successful pivot.
|
|
* @old_nd contains the nameidata structure for the old root.
|
|
* @new_nd contains the nameidata structure for the new root.
|
|
*
|
|
* Security hooks for inode operations.
|
|
*
|
|
* @inode_alloc_security:
|
|
* Allocate and attach a security structure to @inode->i_security. The
|
|
* i_security field is initialized to NULL when the inode structure is
|
|
* allocated.
|
|
* @inode contains the inode structure.
|
|
* Return 0 if operation was successful.
|
|
* @inode_free_security:
|
|
* @inode contains the inode structure.
|
|
* Deallocate the inode security structure and set @inode->i_security to
|
|
* NULL.
|
|
* @inode_init_security:
|
|
* Obtain the security attribute name suffix and value to set on a newly
|
|
* created inode and set up the incore security field for the new inode.
|
|
* This hook is called by the fs code as part of the inode creation
|
|
* transaction and provides for atomic labeling of the inode, unlike
|
|
* the post_create/mkdir/... hooks called by the VFS. The hook function
|
|
* is expected to allocate the name and value via kmalloc, with the caller
|
|
* being responsible for calling kfree after using them.
|
|
* If the security module does not use security attributes or does
|
|
* not wish to put a security attribute on this particular inode,
|
|
* then it should return -EOPNOTSUPP to skip this processing.
|
|
* @inode contains the inode structure of the newly created inode.
|
|
* @dir contains the inode structure of the parent directory.
|
|
* @name will be set to the allocated name suffix (e.g. selinux).
|
|
* @value will be set to the allocated attribute value.
|
|
* @len will be set to the length of the value.
|
|
* Returns 0 if @name and @value have been successfully set,
|
|
* -EOPNOTSUPP if no security attribute is needed, or
|
|
* -ENOMEM on memory allocation failure.
|
|
* @inode_create:
|
|
* Check permission to create a regular file.
|
|

|
|
* @dir contains the inode structure of parent directory of the file.

|
|
* @old_name contains the pathname of file.
|
|
* Return 0 if permission is granted.
|
|
* @inode_mkdir:
|
|
* Check permissions to create a new directory in the existing directory
|
|
* associated with inode strcture @dir.
|
|
* @dir containst the inode structure of parent of the directory to be created.
|
|

|
|
* @mode contains the mode of new directory.
|
|
* Return 0 if permission is granted.
|
|
* @inode_rmdir:
|
|
* Check the permission to remove a directory.
|
|
* @dir contains the inode structure of parent of the directory to be removed.
|
|
* @dentry contains the dentry structure of directory to be removed.
|
|
* Return 0 if permission is granted.
|
|
* @inode_mknod:
|
|
* Check permissions when creating a special file (or a socket or a fifo
|
|
* file created via the mknod system call). Note that if mknod operation
|
|
* is being done for a regular file, then the create hook will be called
|
|
* and not this hook.
|
|
* @dir contains the inode structure of parent of the new file.
|
|
* @dentry contains the dentry structure of the new file.
|
|

|
|
* @dentry contains the dentry structure for the link.
|
|
* @nd contains the nameidata structure for the parent directory.
|
|
* Return 0 if permission is granted.
|
|
* @inode_permission:
|
|
* Check permission before accessing an inode. This hook is called by the
|
|
* existing Linux permission function, so a security module can use it to
|
|
* provide additional checking for existing Linux permission checks.
|
|
* Notice that this hook is called when a file is opened (as well as many
|
|
* other operations), whereas the file_security_ops permission hook is
|
|
* called when the actual read/write operations are performed.
|
|
* @inode contains the inode structure to check.
|

|
|
* operations, transferring disk quotas, etc).
|

* @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.
|
|
* Return 0 if permission is granted.
|
|
* @inode_post_setxattr:
|
|
* Update inode security field after successful setxattr operation.
|
|
* @value identified by @name for @dentry.
|
|
* @inode_getxattr:
|
|
* Check permission before obtaining the extended attributes
|
|
* identified by @name for @dentry.
|
|
* Return 0 if permission is granted.
|
|
* @inode_listxattr:
|
|
* Check permission before obtaining the list of extended attribute
|
|
* names for @dentry.
|
|
* Return 0 if permission is granted.
|
|
* @inode_removexattr:
|
|
* Check permission before removing the extended attribute
|
|
* identified by @name for @dentry.
|
|
* Return 0 if permission is granted.
|
|
* @inode_getsecurity:
|
|
* Copy the extended attribute representation of the security label
|
|
* associated with @name for @inode into @buffer. @buffer may be
|
|
* NULL to request the size of the buffer required. @size indicates
|
|
* the size of @buffer in bytes. Note that @name is the remainder
|
|
* of the attribute name after the security. prefix has been removed.
|
|
* Return number of bytes used/required on success.
|
|
* @inode_setsecurity:
|
|
* Set the security label associated with @name for @inode from the
|
|
* extended attribute value @value. @size indicates the size of the
|
|
* @value in bytes. @flags may be XATTR_CREATE, XATTR_REPLACE, or 0.
|
|
* Note that @name is the remainder of the attribute name after the
|
|
* security. prefix has been removed.
|
|
* Return 0 on success.
|
|
* @inode_listsecurity:
|
|
* Copy the extended attribute names for the security labels
|
|
* associated with @inode into @buffer. The maximum size of @buffer
|
|
* is specified by @buffer_size. @buffer may be NULL to request
|
|
* the size of the buffer required.
|
|
* Returns number of bytes used/required on success.
|
|
*
|
|
* Security hooks for file operations
|
|
*
|
|
* @file_permission:
|
|
* Check file permissions before accessing an open file. This hook is
|
|
* called by various operations that read or write files. A security
|
|
* module can use this hook to perform additional checking on these
|
|
* operations, e.g. to revalidate permissions on use to support privilege
|
|
* bracketing or policy changes. Notice that this hook is used when the
|
|
* actual read/write operations are performed, whereas the
|
|
* inode_security_ops hook is called when a file is opened (as well as
|
|
* many other operations).
|
|
* Caveat: Although this hook can be used to revalidate permissions for
|
|
* various system call operations that read or write files, it does not
|
|
* address the revalidation of permissions for memory-mapped files.
|
|
* Security modules must handle this separately if they need such
|
|
* revalidation.
|
|
* @file contains the file structure being accessed.
|
|
* @mask contains the requested permissions.
|
|
* Return 0 if permission is granted.
|
|
* @file_alloc_security:
|
|
* Allocate and attach a security structure to the file->f_security field.
|
|
* The security field is initialized to NULL when the structure is first
|
|
* created.

* domain sockets. Whereas binding and connecting to sockets in the file name
|
|
* space is mediated by the typical file permissions (and caught by the mknod
|
|
* and permission hooks in inode_security_ops), binding and connecting to
|
|
* sockets in the abstract name space is completely unmediated. Sufficient
|
|
* control of Unix domain sockets in the abstract name space isn't possible
|
|
* using only the socket layer hooks, since we need to know the actual target

* @shm_shmctl:
|
|
* Check permission when a shared memory control operation specified by
|
|
* @cmd is to be performed on the shared memory region @shp.
|
|
* The @shp may be NULL, e.g. for IPC_INFO or SHM_INFO.
|
|
* @shp contains shared memory structure to be modified.
|
|
* @cmd contains the operation to be performed.
|
|
* Return 0 if permission is granted.
|
|
* @shm_shmat:
|
|
* Check permissions prior to allowing the shmat system call to attach the
|
|
* shared memory segment @shp to the data segment of the calling process.
|
|
* The attaching address is specified by @shmaddr.
|
|
* @shp contains the shared memory structure to be modified.
|
|
* @shmaddr contains the address to attach memory region to.
|
|
* @shmflg contains the operational flags.

|
* Return 0 if permission is granted.
|
|
*
|
|
* Security hooks for System V Semaphores
|
|
*
|
|
* @sem_alloc_security:
|
|
* Allocate and attach a security structure to the sma->sem_perm.security
|
|
* field. The security field is initialized to NULL when the structure is
|
|
* first created.
|
|
* @sma contains the semaphore structure
|
|
* Return 0 if operation was successful and permission is granted.
|
|
* @sem_free_security:
|
|
* deallocate security struct for this semaphore
|
|
* @sma contains the semaphore structure.
|
|
* @sem_associate:
|
|
* Check permission when a semaphore is requested through the semget
|
|
* system call. This hook is only called when returning the semaphore
|
|
* identifier for an existing semaphore, not when a new one must be
|
|
* created.
|
|
* @sma contains the semaphore structure.
|
|
* @semflg contains the operation control flags.
|
|
* Return 0 if permission is granted.
|
|
* @sem_semctl:
|
|
* Check permission when a semaphore operation specified by @cmd is to be
|
|
* performed on the semaphore @sma. The @sma may be NULL, e.g. for
|
|
* IPC_INFO or SEM_INFO.
|
|
* @sma contains the semaphore structure. May be NULL.
|
|
* @cmd contains the operation to be performed.
|
|
* Return 0 if permission is granted.
|
|
* @sem_semop
|
|
* Check permissions before performing operations on members of the
|
|
* semaphore set @sma. If the @alter flag is nonzero, the semaphore set
|
|
* may be modified.
|
|
* @sma contains the semaphore structure.
|
|
* @sops contains the operations to perform.
|
|
* @nsops contains the number of operations to perform.
|
|
* @alter contains the flag indicating whether changes are to be made.
|
|
* Return 0 if permission is granted.
|
|
*
|
|
* @ptrace:
|
|
* Check permission before allowing the @parent process to trace the
|
|
* @child process.
|
|
* Security modules may also want to perform a process tracing check
|
|
* during an execve in the set_security or apply_creds hooks of
|
|
* binprm_security_ops if the process is being traced and its security
|
|
* attributes would be changed by the execve.
|
|
* @parent contains the task_struct structure for parent process.
|
|
* @child contains the task_struct structure for child process.
|
|
* Return 0 if permission is granted.
|
|
* @capget:
|
|
* Get the @effective, @inheritable, and @permitted capability sets for
|
|
* the @target process. The hook may also perform permission checking to
|
|
* determine if the current process is allowed to see the capability sets
|
|
* of the @target process.
|
|
* @target contains the task_struct structure for target process.
|
|
* @effective contains the effective capability set.
|
|
* @inheritable contains the inheritable capability set.
|
|
* @permitted contains the permitted capability set.
|
|
* Return 0 if the capability sets were successfully obtained.
|
|
* @capset_check:
|
|
* Check permission before setting the @effective, @inheritable, and
|
|
* @permitted capability sets for the @target process.
|
|
* Caveat: @target is also set to current if a set of processes is
|
|
* specified (i.e. all processes other than current and init or a
|
|
* particular process group). Hence, the capset_set hook may need to
|
|
* revalidate permission to the actual target process.
|
|
* @target contains the task_struct structure for target process.
|
|
* @effective contains the effective capability set.
|
|
* @inheritable contains the inheritable capability set.
|
|
* @permitted contains the permitted capability set.
|
|
* Return 0 if permission is granted.
|
|
* @capset_set:
|
|
* Set the @effective, @inheritable, and @permitted capability sets for
|
|
* the @target process. Since capset_check cannot always check permission
|
|
* to the real @target process, this hook may also perform permission
|
|
* checking to determine if the current process is allowed to set the
|
|
* capability sets of the @target process. However, this hook has no way
|
|
* of returning an error due to the structure of the sys_capset code.
|
|
* @target contains the task_struct structure for target process.
|
|
* @effective contains the effective capability set.
|
|
* @inheritable contains the inheritable capability set.
|
|
* @permitted contains the permitted capability set.
|
|
* @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.
|
|
* @table contains the ctl_table structure for the sysctl variable.
|
|
* @op contains the operation (001 = search, 002 = write, 004 = read).
|
|
* Return 0 if permission is granted.
|
|
* @capable:
|
|
* Check whether the @tsk process has the @cap capability.
|
|
* @tsk contains the task_struct for the process.
|
|
* @cap contains the capability <include/linux/capability.h>.
|
|
* Return 0 if the capability is granted for @tsk.
|
|
* @syslog:
|
|
* Check permission before accessing the kernel message ring or changing
|
|
* logging to the console.
|
|
* See the syslog(2) manual page for an explanation of the @type values.
|
|
* @type contains the type of action.
|
|
* Return 0 if permission is granted.
|
|
* @settime:
|
|
* Check permission to change the system time.
|
|
* struct timespec and timezone are defined in include/linux/time.h
|
|
* @ts contains new time
|
|
* @tz contains new timezone
|
|
* Return 0 if permission is granted.
|
|
* @vm_enough_memory:
|
|
* Check permissions for allocating a new virtual mapping.
|
|
* @pages contains the number of pages.
|
|
* Return 0 if permission is granted.
|
|
*
|
|
* @register_security:
|
|
* allow module stacking.
|
|
* @name contains the name of the security module being stacked.
|
|
* @ops contains a pointer to the struct security_operations of the module to stack.
|
|
* @unregister_security:
|
|
* remove a stacked module.
|
|
* @name contains the name of the security module being unstacked.
|
|
* @ops contains a pointer to the struct security_operations of the module to unstack.
|
|
*
|
|
* This is the main security structure.
