These changes are the raw update to linux-4.4.6-rt14. Kernel sources

are taken from kernel.org, and rt patch from the rt wiki download page.

During the rebasing, the following patch collided:

Force tick interrupt and get rid of softirq magic(I70131fb85).

Collisions have been removed because its logic was found on the
source already.

- *	@seq: Sequence number for IV generation
- *	@giv: Space for generated IV
- *	@areq: The AEAD request itself
+ * DOC: Authenticated Encryption With Associated Data (AEAD) Cipher API
+ *
+ * The AEAD cipher API is used with the ciphers of type CRYPTO_ALG_TYPE_AEAD
+ * (listed as type "aead" in /proc/crypto)
+ *
+ * The most prominent examples for this type of encryption is GCM and CCM.
+ * However, the kernel supports other types of AEAD ciphers which are defined
+ * with the following cipher string:
+ *
+ *	authenc(keyed message digest, block cipher)
+ *
+ * For example: authenc(hmac(sha256), cbc(aes))
+ *
+ * The example code provided for the asynchronous block cipher operation
+ * applies here as well. Naturally all *ablkcipher* symbols must be exchanged
+ * the *aead* pendants discussed in the following. In addition, for the AEAD
+ * operation, the aead_request_set_assoc function must be used to set the
+ * pointer to the associated data memory location before performing the
+ * encryption or decryption operation. In case of an encryption, the associated
+ * data memory is filled during the encryption operation. For decryption, the
+ * associated data memory must contain data that is used to verify the integrity
+ * of the decrypted data. Another deviation from the asynchronous block cipher
+ * operation is that the caller should explicitly check for -EBADMSG of the
+ * crypto_aead_decrypt. That error indicates an authentication error, i.e.
+ * a breach in the integrity of the message. In essence, that -EBADMSG error
+ * code is the key bonus an AEAD cipher has over "standard" block chaining
+ * modes.
+ *
+ * Memory Structure:
+ *
+ * To support the needs of the most prominent user of AEAD ciphers, namely
+ * IPSEC, the AEAD ciphers have a special memory layout the caller must adhere
+ * to.
+ *
+ * The scatter list pointing to the input data must contain:
+ *
+ * * for RFC4106 ciphers, the concatenation of
+ * associated authentication data || IV || plaintext or ciphertext. Note, the
+ * same IV (buffer) is also set with the aead_request_set_crypt call. Note,
+ * the API call of aead_request_set_ad must provide the length of the AAD and
+ * the IV. The API call of aead_request_set_crypt only points to the size of
+ * the input plaintext or ciphertext.
+ *
+ * * for "normal" AEAD ciphers, the concatenation of
+ * associated authentication data || plaintext or ciphertext.
+ *
+ * It is important to note that if multiple scatter gather list entries form
+ * the input data mentioned above, the first entry must not point to a NULL
+ * buffer. If there is any potential where the AAD buffer can be NULL, the
+ * calling code must contain a precaution to ensure that this does not result
+ * in the first scatter gather list entry pointing to a NULL buffer.

- * - rename(2) is disallowed.
- *
- * - "tasks" is removed.  Everything should be at process granularity.  Use

- *
- * - "cgroup.procs" is not sorted.  pids will be unique unless they got

- *
- * - "release_agent" and "notify_on_release" are removed.  Replacement

- *
- * - "cgroup.clone_children" is removed.
- *
- * - "cgroup.subtree_populated" is available.  Its value is 0 if the cgroup

- *

- *
- * If checking parent's state requires locking the parent, each inheriting

- * DOC: Authenticated Encryption With Associated Data (AEAD) Cipher API
- *
- * The AEAD cipher API is used with the ciphers of type CRYPTO_ALG_TYPE_AEAD
- * (listed as type "aead" in /proc/crypto)
- *
- * The most prominent examples for this type of encryption is GCM and CCM.
- * However, the kernel supports other types of AEAD ciphers which are defined
- * with the following cipher string:
- *
- *	authenc(keyed message digest, block cipher)
- *
- * For example: authenc(hmac(sha256), cbc(aes))
- *
- * The example code provided for the asynchronous block cipher operation
- * applies here as well. Naturally all *ablkcipher* symbols must be exchanged
- * the *aead* pendants discussed in the following. In addtion, for the AEAD
- * operation, the aead_request_set_assoc function must be used to set the
- * pointer to the associated data memory location before performing the
- * encryption or decryption operation. In case of an encryption, the associated
- * data memory is filled during the encryption operation. For decryption, the
- * associated data memory must contain data that is used to verify the integrity
- * of the decrypted data. Another deviation from the asynchronous block cipher
- * operation is that the caller should explicitly check for -EBADMSG of the
- * crypto_aead_decrypt. That error indicates an authentication error, i.e.
- * a breach in the integrity of the message. In essence, that -EBADMSG error
- * code is the key bonus an AEAD cipher has over "standard" block chaining

+ * Useful GFP flag combinations that are commonly used. It is recommended

+ * __GFP_FOO flags as necessary.
+ *
+ * GFP_ATOMIC users can not sleep and need the allocation to succeed. A lower
+ *   watermark is applied to allow access to "atomic reserves"
+ *
+ * GFP_KERNEL is typical for kernel-internal allocations. The caller requires
+ *   ZONE_NORMAL or a lower zone for direct access but can direct reclaim.
+ *
+ * GFP_NOWAIT is for kernel allocations that should not stall for direct
+ *   reclaim, start physical IO or use any filesystem callback.
+ *
+ * GFP_NOIO will use direct reclaim to discard clean pages or slab pages
+ *   that do not require the starting of any physical IO.
+ *
+ * GFP_NOFS will use direct reclaim but will not use any filesystem interfaces.
+ *
+ * GFP_USER is for userspace allocations that also need to be directly
+ *   accessibly by the kernel or hardware. It is typically used by hardware
+ *   for buffers that are mapped to userspace (e.g. graphics) that hardware
+ *   still must DMA to. cpuset limits are enforced for these allocations.
+ *
+ * GFP_DMA exists for historical reasons and should be avoided where possible.
+ *   The flags indicates that the caller requires that the lowest zone be
+ *   used (ZONE_DMA or 16M on x86-64). Ideally, this would be removed but
+ *   it would require careful auditing as some users really require it and
+ *   others use the flag to avoid lowmem reserves in ZONE_DMA and treat the
+ *   lowest zone as a type of emergency reserve.
+ *
+ * GFP_DMA32 is similar to GFP_DMA except that the caller requires a 32-bit
+ *   address.
+ *
+ * GFP_HIGHUSER is for userspace allocations that may be mapped to userspace,
+ *   do not need to be directly accessible by the kernel but that cannot
+ *   move once in use. An example may be a hardware allocation that maps
+ *   data directly into userspace but has no addressing limitations.
+ *
+ * GFP_HIGHUSER_MOVABLE is for userspace allocations that the kernel does not
+ *   need direct access to but can use kmap() when access is required. They
+ *   are expected to be movable via page reclaim or page migration. Typically,
+ *   pages on the LRU would also be allocated with GFP_HIGHUSER_MOVABLE.
+ *
+ * GFP_TRANSHUGE is used for THP allocations. They are compound allocations
+ *   that will fail quickly if memory is not available and will not wake
+ *   kswapd on failure.

+ * Similarly, we can define an initially true key via

+ * At runtime we can change the branch target by setting the key

+ * static_branch_disable(). If the direction of the branch is switched by

+ * to the out-of-line of true branch.
  *
- * However at runtime we can change the branch target using
- * static_key_slow_{inc,dec}(). These function as a 'reference' count on the key

- * that particular key will point to the (out of line) true block.
+ * In addition to static_branch_{enable,disable}, we can also reference count
+ * the key or branch direction via static_branch_{inc,dec}. Thus,
+ * static_branch_inc() can be thought of as a 'make more true' and
+ * static_branch_dec() as a 'make more false'.
  *

+/**
+ * Security hooks for program execution operations.
+ *
+ * @bprm_set_creds:
+ *	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_creds call.  The primary difference from set_creds 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_creds is called first.
+ *	@bprm contains the linux_binprm structure.
+ *	Return 0 if the hook is successful and permission is granted.
+ * @bprm_committing_creds:
+ *	Prepare to install the new security attributes of a process being
+ *	transformed by an execve operation, based on the old credentials
+ *	pointed to by @current->cred and the information set in @bprm->cred by
+ *	the bprm_set_creds hook.  @bprm points to the linux_binprm structure.
+ *	This hook is a good place to perform state changes on the process such
+ *	as closing open file descriptors to which access will no longer be
+ *	granted when the attributes are changed.  This is called immediately
+ *	before commit_creds().
+ * @bprm_committed_creds:
+ *	Tidy up after the installation of the new security attributes of a
+ *	process being transformed by an execve operation.  The new credentials
+ *	have, by this point, been set to @current->cred.  @bprm points to the
+ *	linux_binprm structure.  This hook is a good place to perform state
+ *	changes on the process such as clearing out non-inheritable signal
+ *	state.  This is called immediately after commit_creds().
+ * @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 @mnt
+ *	mountpoint.
+ *	@dentry is a handle on the superblock 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.
+ *	@path contains the path 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_remount:
+ *	Extracts security system specific mount options and verifies no changes
+ *	are being made to those options.
+ *	@sb superblock being remounted
+ *	@data contains the filesystem-specific data.
+ *	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_pivotroot:
+ *	Check permission before pivoting the root filesystem.
+ *	@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_set_mnt_opts:
+ *	Set the security relevant mount options used for a superblock
+ *	@sb the superblock to set security mount options for
+ *	@opts binary data structure containing all lsm mount data
+ * @sb_clone_mnt_opts:
+ *	Copy all security options from a given superblock to another
+ *	@oldsb old superblock which contain information to clone
+ *	@newsb new superblock which needs filled in
+ * @sb_parse_opts_str:
+ *	Parse a string of security data filling in the opts structure
+ *	@options string containing all mount options known by the LSM
+ *	@opts binary data structure usable by the LSM
+ * @dentry_init_security:
+ *	Compute a context for a dentry as the inode is not yet available
+ *	since NFSv4 has no label backed by an EA anyway.
+ *	@dentry dentry to use in calculating the context.
+ *	@mode mode used to determine resource type.
+ *	@name name of the last path component used to create file
+ *	@ctx pointer to place the pointer to the resulting context in.
+ *	@ctxlen point to place the length of the resulting context.
+ *
+ *
+ * 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.
+ *	@qstr contains the last path component of the new object
+ *	@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 inode structure of the parent of the new file.
+ *	@dentry contains the dentry structure for the file to be created.
+ *	@mode contains the file mode of the file to be created.
+ *	Return 0 if permission is granted.
+ * @inode_link:
+ *	Check permission before creating a new hard link to a file.
+ *	@old_dentry contains the dentry structure for an existing
+ *	link to the file.
+ *	@dir contains the inode structure of the parent directory
+ *	of the new link.
+ *	@new_dentry contains the dentry structure for the new link.
+ *	Return 0 if permission is granted.
+ * @path_link:
+ *	Check permission before creating a new hard link to a file.
+ *	@old_dentry contains the dentry structure for an existing link
+ *	to the file.
+ *	@new_dir contains the path structure of the parent directory of
+ *	the new link.
+ *	@new_dentry contains the dentry structure for the new link.
+ *	Return 0 if permission is granted.
+ * @inode_unlink:
+ *	Check the permission to remove a hard link to a file.

+ * Security hooks for file operations
+ *
+ * @file_permission:

+ *	Check permission for the file owner @fown to send SIGIO or SIGURG to the

- * We cache key information from each zonelist for smaller cache
- * footprint when scanning for free pages in get_page_from_freelist().
- *
- * 1) The BITMAP fullzones tracks which zones in a zonelist have come
- *    up short of free memory since the last time (last_fullzone_zap)
- *    we zero'd fullzones.
- * 2) The array z_to_n[] maps each zone in the zonelist to its node
- *    id, so that we can efficiently evaluate whether that node is
- *    set in the current tasks mems_allowed.
- *
- * Both fullzones and z_to_n[] are one-to-one with the zonelist,
- * indexed by a zones offset in the zonelist zones[] array.
- *
- * The get_page_from_freelist() routine does two scans.  During the
- * first scan, we skip zones whose corresponding bit in 'fullzones'
- * is set or whose corresponding node in current->mems_allowed (which
- * comes from cpusets) is not set.  During the second scan, we bypass
- * this zonelist_cache, to ensure we look methodically at each zone.
- *
- * Once per second, we zero out (zap) fullzones, forcing us to
- * reconsider nodes that might have regained more free memory.
- * The field last_full_zap is the time we last zapped fullzones.
- *
- * This mechanism reduces the amount of time we waste repeatedly
- * reexaming zones for free memory when they just came up low on
- * memory momentarilly ago.
- *
- * The zonelist_cache struct members logically belong in struct
- * zonelist.  However, the mempolicy zonelists constructed for
- * MPOL_BIND are intentionally variable length (and usually much
- * shorter).  A general purpose mechanism for handling structs with
- * multiple variable length members is more mechanism than we want
- * here.  We resort to some special case hackery instead.
- *
- * The MPOL_BIND zonelists don't need this zonelist_cache (in good
- * part because they are shorter), so we put the fixed length stuff
- * at the front of the zonelist struct, ending in a variable length
- * zones[], as is needed by MPOL_BIND.
- *
- * Then we put the optional zonelist cache on the end of the zonelist
- * struct.  This optional stuff is found by a 'zlcache_ptr' pointer in
- * the fixed length portion at the front of the struct.  This pointer
- * both enables us to find the zonelist cache, and in the case of
- * MPOL_BIND zonelists, (which will just set the zlcache_ptr to NULL)
- * to know that the zonelist cache is not there.
- *
- * The end result is that struct zonelists come in two flavors:
- *  1) The full, fixed length version, shown below, and
- *  2) The custom zonelists for MPOL_BIND.
- * The custom MPOL_BIND zonelists have a NULL zlcache_ptr and no zlcache.
- *
- * Even though there may be multiple CPU cores on a node modifying
- * fullzones or last_full_zap in the same zonelist_cache at the same
- * time, we don't lock it.  This is just hint data - if it is wrong now
- * and then, the allocator will still function, perhaps a bit slower.

+ * Latched RB-trees
+ *
+ * Copyright (C) 2015 Intel Corp., Peter Zijlstra <peterz@infradead.org>
+ *
+ * Since RB-trees have non-atomic modifications they're not immediately suited
+ * for RCU/lockless queries. Even though we made RB-tree lookups non-fatal for
+ * lockless lookups; we cannot guarantee they return a correct result.
+ *
+ * The simplest solution is a seqlock + RB-tree, this will allow lockless
+ * lookups; but has the constraint (inherent to the seqlock) that read sides
+ * cannot nest in write sides.
+ *
+ * If we need to allow unconditional lookups (say as required for NMI context
+ * usage) we need a more complex setup; this data structure provides this by
+ * employing the latch technique -- see @raw_write_seqcount_latch -- to
+ * implement a latched RB-tree which does allow for unconditional lookups by
+ * virtue of always having (at least) one stable copy of the tree.
+ *
+ * However, while we have the guarantee that there is at all times one stable
+ * copy, this does not guarantee an iteration will not observe modifications.
+ * What might have been a stable copy at the start of the iteration, need not
+ * remain so for the duration of the iteration.
+ *
+ * Therefore, this does require a lockless RB-tree iteration to be non-fatal;
+ * see the comment in lib/rbtree.c. Note however that we only require the first
+ * condition -- not seeing partial stores -- because the latch thing isolates
+ * us from loops. If we were to interrupt a modification the lookup would be
+ * pointed at the stable tree and complete while the modification was halted.

+ *
+ * The scif_register() function opens a window, a range of whole pages of the

+ * and continuing for len bytes. addr and len are constrained to be multiples
+ * of the page size. A successful scif_register() call returns po.
+ *
+ * When SCIF_MAP_FIXED is set in the map_flags argument, po will be offset

+ * suitable for a mapping of len bytes. An offset value of 0 is interpreted as
+ * granting the implementation complete freedom in selecting po, subject to
+ * constraints described below. A non-zero value of offset is taken to be a
+ * suggestion of an offset near which the mapping should be placed. When the
+ * implementation selects a value for po, it does not replace any extant
+ * window. In all cases, po will be a multiple of the page size.
+ *
+ * The physical pages which are so represented by a window are available for

+ * scif_poll() waits for one of a set of endpoints to become ready to perform

+ *
+ * The epds argument specifies the endpoint descriptors to be examined and the

+ * array with one member for each open endpoint descriptor of interest.
+ *
+ * The number of items in the epds array is specified in nepds. The epd field
+ * of scif_pollepd is an endpoint descriptor of an open endpoint. The field
+ * events is a bitmask specifying the events which the application is
+ * interested in. The field revents is an output parameter, filled by the
+ * kernel with the events that actually occurred. The bits returned in revents
+ * can include any of those specified in events, or one of the values POLLERR,

+ * timeout means an infinite timeout.
+ *
+ * The following bits may be set in events and returned in revents.
+ * POLLIN - Data may be received without blocking. For a connected
+ * endpoint, this means that scif_recv() may be called without blocking. For a
+ * listening endpoint, this means that scif_accept() may be called without
+ * blocking.
+ * POLLOUT - Data may be sent without blocking. For a connected endpoint, this
+ * means that scif_send() may be called without blocking. POLLOUT may also be
+ * used to block waiting for a non-blocking connect to complete. This bit value
+ * has no meaning for a listening endpoint and is ignored if specified.
+ *
+ * The following bits are only returned in revents, and are ignored if set in
+ * events.
+ * POLLERR - An error occurred on the endpoint
+ * POLLHUP - The connection to the peer endpoint was disconnected
+ * POLLNVAL - The specified endpoint descriptor is invalid.
+ *
+ * Return:
+ * Upon successful completion, scif_poll() returns a non-negative value. A
+ * positive value indicates the total number of endpoint descriptors that have
+ * been selected (that is, endpoint descriptors for which the revents member is
+ * non-zero). A value of 0 indicates that the call timed out and no endpoint
+ * descriptors have been selected. Otherwise in user mode -1 is returned and
+ * errno is set to indicate the error; in kernel mode the negative of one of
+ * the following errors is returned.
+ *
+ * Errors:

- * struct security_operations - main security structure
- *
- * Security module identifier.
- *
- * @name:
- *	A string that acts as a unique identifier for the LSM with max number
- *	of characters = SECURITY_NAME_MAX.
- *
- * Security hooks for program execution operations.
- *
- * @bprm_set_creds:
- *	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_creds call.  The primary difference from set_creds 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_creds is called first.
- *	@bprm contains the linux_binprm structure.
- *	Return 0 if the hook is successful and permission is granted.
- * @bprm_committing_creds:
- *	Prepare to install the new security attributes of a process being
- *	transformed by an execve operation, based on the old credentials
- *	pointed to by @current->cred and the information set in @bprm->cred by
- *	the bprm_set_creds hook.  @bprm points to the linux_binprm structure.
- *	This hook is a good place to perform state changes on the process such
- *	as closing open file descriptors to which access will no longer be
- *	granted when the attributes are changed.  This is called immediately
- *	before commit_creds().
- * @bprm_committed_creds:
- *	Tidy up after the installation of the new security attributes of a
- *	process being transformed by an execve operation.  The new credentials
- *	have, by this point, been set to @current->cred.  @bprm points to the
- *	linux_binprm structure.  This hook is a good place to perform state
- *	changes on the process such as clearing out non-inheritable signal
- *	state.  This is called immediately after commit_creds().
- * @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 @mnt
- *	mountpoint.
- *	@dentry is a handle on the superblock 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.
- *	@path contains the path 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_remount:
- *	Extracts security system specific mount options and verifies no changes
- *	are being made to those options.
- *	@sb superblock being remounted
- *	@data contains the filesystem-specific data.
- *	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_pivotroot:
- *	Check permission before pivoting the root filesystem.
- *	@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_set_mnt_opts:
- *	Set the security relevant mount options used for a superblock
- *	@sb the superblock to set security mount options for
- *	@opts binary data structure containing all lsm mount data
- * @sb_clone_mnt_opts:
- *	Copy all security options from a given superblock to another
- *	@oldsb old superblock which contain information to clone
- *	@newsb new superblock which needs filled in
- * @sb_parse_opts_str:
- *	Parse a string of security data filling in the opts structure
- *	@options string containing all mount options known by the LSM
- *	@opts binary data structure usable by the LSM
- * @dentry_init_security:
- *	Compute a context for a dentry as the inode is not yet available
- *	since NFSv4 has no label backed by an EA anyway.
- *	@dentry dentry to use in calculating the context.
- *	@mode mode used to determine resource type.
- *	@name name of the last path component used to create file
- *	@ctx pointer to place the pointer to the resulting context in.
- *	@ctxlen point to place the length of the resulting context.
- *
- *
- * 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.
- *	@qstr contains the last path component of the new object
- *	@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.

- *	Check permission to create a regular file.

- * Security hooks for file operations
- *
- * @file_permission:

- * @file_send_sigiotask:
- *	Check permission for the file owner @fown to send SIGIO or SIGURG to the

  * raw_write_seqcount_latch - redirect readers to even/odd copy
  * @s: pointer to seqcount_t
+ *
+ * The latch technique is a multiversion concurrency control method that allows
+ * queries during non-atomic modifications. If you can guarantee queries never
+ * interrupt the modification -- e.g. the concurrency is strictly between CPUs
+ * -- you most likely do not need this.
+ *
+ * Where the traditional RCU/lockless data structures rely on atomic
+ * modifications to ensure queries observe either the old or the new state the
+ * latch allows the same for non-atomic updates. The trade-off is doubling the
+ * cost of storage; we have to maintain two copies of the entire data
+ * structure.
+ *
+ * Very simply put: we first modify one copy and then the other. This ensures
+ * there is always one copy in a stable state, ready to give us an answer.
+ *
+ * The basic form is a data structure like:
+ *
+ * struct latch_struct {
+ *	seqcount_t		seq;
+ *	struct data_struct	data[2];
+ * };
+ *
+ * Where a modification, which is assumed to be externally serialized, does the
+ * following:
+ *
+ * void latch_modify(struct latch_struct *latch, ...)
+ * {
+ *	smp_wmb();	<- Ensure that the last data[1] update is visible
+ *	latch->seq++;
+ *	smp_wmb();	<- Ensure that the seqcount update is visible
+ *
+ *	modify(latch->data[0], ...);
+ *
+ *	smp_wmb();	<- Ensure that the data[0] update is visible
+ *	latch->seq++;
+ *	smp_wmb();	<- Ensure that the seqcount update is visible
+ *
+ *	modify(latch->data[1], ...);
+ * }
+ *
+ * The query will have a form like:
+ *
+ * struct entry *latch_query(struct latch_struct *latch, ...)
+ * {
+ *	struct entry *entry;
+ *	unsigned seq, idx;
+ *
+ *	do {
+ *		seq = lockless_dereference(latch->seq);
+ *
+ *		idx = seq & 0x01;
+ *		entry = data_query(latch->data[idx], ...);
+ *
+ *		smp_rmb();
+ *	} while (seq != latch->seq);
+ *
+ *	return entry;
+ * }
+ *
+ * So during the modification, queries are first redirected to data[1]. Then we
+ * modify data[0]. When that is complete, we redirect queries back to data[0]
+ * and we can modify data[1].
+ *
+ * NOTE: The non-requirement for atomic modifications does _NOT_ include
+ *       the publishing of new entries in the case where data is a dynamic
+ *       data structure.
+ *
+ *       An iteration might start in data[0] and get suspended long enough
+ *       to miss an entire modification sequence, once it resumes it might
+ *       observe the new entry.
+ *
+ * NOTE: When data is a dynamic data structure; one should use regular RCU
+ *       patterns to manage the lifetimes of the objects within.

+ *			value, then the first free minor number will be used
+ *			(if available).
+ *
+ * @code_length:	length of the remote control key code expressed in bits.
+ *
+ * @buffer_size:	Number of FIFO buffers with @chunk_size size. If zero,
+ *			creates a buffer with BUFLEN size (16 bytes).
+ *
+ * @sample_rate:	if zero, the device will wait for an event with a new
+ *			code to be parsed. Otherwise, specifies the sample
+ *			rate for polling. Value should be between 0
+ *			and HZ. If equal to HZ, it would mean one polling per
+ *			second.
+ *
+ * @features:		lirc compatible hardware features, like LIRC_MODE_RAW,
+ *			LIRC_CAN_*, as defined at include/media/lirc.h.
+ *
+ * @chunk_size:		Size of each FIFO buffer.
+ *
+ * @data:		it may point to any driver data and this pointer will
+ *			be passed to all callback functions.
+ *
+ * @min_timeout:	Minimum timeout for record. Valid only if
+ *			LIRC_CAN_SET_REC_TIMEOUT is defined.
+ *
+ * @max_timeout:	Maximum timeout for record. Valid only if
+ *			LIRC_CAN_SET_REC_TIMEOUT is defined.
+ *
+ * @add_to_buf:		add_to_buf will be called after specified period of the
+ *			time or triggered by the external event, this behavior
+ *			depends on value of the sample_rate this function will
+ *			be called in user context. This routine should return
+ *			0 if data was added to the buffer and -ENODATA if none
+ *			was available. This should add some number of bits
+ *			evenly divisible by code_length to the buffer.
+ *
+ * @rbuf:		if not NULL, it will be used as a read buffer, you will
+ *			have to write to the buffer by other means, like irq's
+ *			(see also lirc_serial.c).
+ *
+ * @set_use_inc:	set_use_inc will be called after device is opened
+ *
+ * @set_use_dec:	set_use_dec will be called after device is closed
+ *
+ * @rdev:		Pointed to struct rc_dev associated with the LIRC
+ *			device.
+ *
+ * @fops:		file_operations for drivers which don't fit the current
+ *			driver model.
+ *			Some ioctl's can be directly handled by lirc_dev if the
+ *			driver's ioctl function is NULL or if it returns
+ *			-ENOIOCTLCMD (see also lirc_serial.c).

+ *				standards, an array should be used, with one
+ *				row per different standard.
+ * @cb_first_if_lower_freq:	Many Philips-based tuners have a comment in

+ *				"For channel selection involving band
+ *				switching, and to ensure smooth tuning to the
+ *				desired channel without causing unnecessary
+ *				charge pump action, it is recommended to
+ *				consider the difference between wanted channel
+ *				frequency and the current channel frequency.
+ *				Unnecessary charge pump action will result
+ *				in very low tuning voltage which may drive the

+ *				Set cb_first_if_lower_freq to 1, if this check
+ *				is required for this tuner. I tested this for
+ *				PAL by first setting the TV frequency to
+ *				203 MHz and then switching to 96.6 MHz FM
+ *				radio. The result was static unless the
+ *				control byte was sent first.
+ * @has_tda9887:		Set to 1 if this tuner uses a tda9887
+ * @port1_fm_high_sensitivity:	Many Philips tuners use tda9887 PORT1 to select
+ *				the FM radio sensitivity. If this setting is 1,
+ *				then set PORT1 to 1 to get proper FM reception.
+ * @port2_fm_high_sensitivity:	Some Philips tuners use tda9887 PORT2 to select
+ *				the FM radio sensitivity. If this setting is 1,

+ * @fm_gain_normal:		Some Philips tuners use tda9887 cGainNormal to

+ *				Some (cheaper) tuners use Intercarrier mode.
+ *				If this setting is 1, then the tuner needs to
+ *				be set to intercarrier mode.
+ * @port1_active:		This setting sets the default value for PORT1.
+ *				0 means inactive, 1 means active. Note: the
+ *				actual bit value written to the tda9887 is
+ *				inverted. So a 0 here means a 1 in the B6 bit.
+ * @port2_active:		This setting sets the default value for PORT2.
+ *				0 means inactive, 1 means active. Note: the
+ *				actual bit value written to the tda9887 is

+ *
+ * The event mask is a per-client mask that specifies which events are

+ *
+ * Event masks do not affect global state of the input device. They only
+ * affect the file descriptor they are applied to.
+ *
+ * The default event mask for a client has all bits set, i.e. all events
+ * are forwarded to the client. If the kernel is queried for an unknown
+ * event type or if the receive buffer is larger than the number of
+ * event codes known to the kernel, the kernel returns all zeroes for those
+ * codes.
+ *
+ * At maximum, codes_size bytes are copied.
