Linux-2.6.12-rc2v2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

+/**
+ * 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

+ *	allocated.
+ *	@inode contains the inode structure.
+ *	Return 0 if operation was successful.
+ * @inode_free_security:
+ *	@inode contains the inode structure.

+ *	@dentry contains the dentry structure of new symbolic link.
+ *	@old_name contains the pathname of file.
+ *	Set security attributes for a newly created symbolic link.  Note that
+ *	@dentry->d_inode may be NULL, since the filesystem might not
+ *	instantiate the dentry (e.g. NFS).
+ * @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_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.

+ *	@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.
+ *	@mask contains the permission mask.
+ *     @nd contains the nameidata (may be NULL).
+ *	Return 0 if permission is granted.
+ * @inode_setattr:
+ *	Check permission before setting file attributes.  Note that the kernel

+ *	Return 0 if permission is granted.
+ * @inode_getattr:

+ *	@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:

+ * @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

+ *	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.
+ *	@file contains the file structure to secure.
+ *	Return 0 if the hook is successful and permission is granted.
+ * @file_free_security:
+ *	Deallocate and free any security structures stored in file->f_security.
+ *	@file contains the file structure being modified.
+ * @file_ioctl:
+ *	@file contains the file structure.
+ *	@cmd contains the operation to perform.
+ *	@arg contains the operational arguments.
+ *	Check permission for an ioctl operation on @file.  Note that @arg can
+ *	sometimes represents a user space pointer; in other cases, it may be a
+ *	simple integer value.  When @arg represents a user space pointer, it
+ *	should never be used by the security module.
+ *	Return 0 if permission is granted.
+ * @file_mmap :
+ *	Check permissions for a mmap operation.  The @file may be NULL, e.g.
+ *	if mapping anonymous memory.
+ *	@file contains the file structure for file to map (may be NULL).
+ *	@reqprot contains the protection requested by the application.
+ *	@prot contains the protection that will be applied by the kernel.
+ *	@flags contains the operational flags.
+ *	Return 0 if permission is granted.
+ * @file_mprotect:
+ *	Check permissions before changing memory access permissions.
+ *	@vma contains the memory region to modify.
+ *	@reqprot contains the protection requested by the application.
+ *	@prot contains the protection that will be applied by the kernel.
+ *	Return 0 if permission is granted.
+ * @file_lock:
+ *	Check permission before performing file locking operations.
+ *	Note: this hook mediates both flock and fcntl style locks.
+ *	@file contains the file structure.
+ *	@cmd contains the posix-translated lock operation to perform
+ *	(e.g. F_RDLCK, F_WRLCK).
+ *	Return 0 if permission is granted.
+ * @file_fcntl:
+ *	Check permission before allowing the file operation specified by @cmd
+ *	from being performed on the file @file.  Note that @arg can sometimes
+ *	represents a user space pointer; in other cases, it may be a simple
+ *	integer value.  When @arg represents a user space pointer, it should
+ *	never be used by the security module.
+ *	@file contains the file structure.
+ *	@cmd contains the operation to be performed.
+ *	@arg contains the operational arguments.
+ *	Return 0 if permission is granted.
+ * @file_set_fowner:
+ *	Save owner security information (typically from current->security) in
+ *	file->f_security for later use by the send_sigiotask hook.
+ *	@file contains the file structure to update.
+ *	Return 0 on success.
+ * @file_send_sigiotask:
+ *	Check permission for the file owner @fown to send SIGIO or SIGURG to the
+ *	process @tsk.  Note that this hook is sometimes called from interrupt.
+ *	Note that the fown_struct, @fown, is never outside the context of a
+ *	struct file, so the file structure (and associated security information)
+ *	can always be obtained:
+ *		(struct file *)((long)fown - offsetof(struct file,f_owner));
+ * 	@tsk contains the structure of task receiving signal.
+ *	@fown contains the file owner information.
+ *	@sig is the signal that will be sent.  When 0, kernel sends SIGIO.
+ *	Return 0 if permission is granted.

+ *	This hook allows security modules to control the ability of a process
+ *	to receive an open file descriptor via socket IPC.

+ *	Return 0 if permission is granted.
+ *
+ * Security hooks for task operations.
+ *
+ * @task_create:
+ *	Check permission before creating a child process.  See the clone(2)
+ *	manual page for definitions of the @clone_flags.
+ *	@clone_flags contains the flags indicating what should be shared.
+ *	Return 0 if permission is granted.
+ * @task_alloc_security:
+ *	@p contains the task_struct for child process.
+ *	Allocate and attach a security structure to the p->security field. The
+ *	security field is initialized to NULL when the task structure is
+ *	allocated.
+ *	Return 0 if operation was successful.
+ * @task_free_security:
+ *	@p contains the task_struct for process.
+ *	Deallocate and clear the p->security field.
