These are the protocols used on the Internet and on most local
Ethernets. It is highly recommended to say Y here (this will enlarge
- your kernel by about 144 KB), since some programs (e.g. the X window
+ your kernel by about 400 KB), since some programs (e.g. the X window
system) use TCP/IP even if your machine is not connected to any
other computer. You will get the so-called loopback device which
allows you to ping yourself (great fun, that!).

+ * (3) hardware/firmware processes TX fifo and suppresses a frame
+ * (4) we get TX status before having processed the frame and
+ * knowing that the STA has gone to sleep.
+ *
+ * This is actually quite unlikely even when both those events are
+ * processed from interrupts coming in quickly after one another or
+ * even at the same time because we queue both TX status events and
+ * RX frames to be processed by a tasklet and process them in the
+ * same order that they were received or TX status last. Hence, there
+ * is no race as long as the frame RX is processed before the next TX
+ * status, which drivers can ensure, see below.
+ *
+ * Note that this can only happen if the hardware or firmware can
+ * actually add STAs to the filter list, if this is done by the
+ * driver in response to set_tim() (which will only reduce the race
+ * this whole filtering tries to solve, not completely solve it)
+ * this situation cannot happen.
+ *
+ * To completely solve this race drivers need to make sure that they
+ * (a) don't mix the irq-safe/not irq-safe TX status/RX processing
+ * functions and
+ * (b) always process RX events before TX status events if ordering
+ * can be unknown, for example with different interrupt status

+/**
+ * DOC: STA information lifetime rules
+ *
+ * STA info structures (&struct sta_info) are managed in a hash table
+ * for faster lookup and a list for iteration. They are managed using
+ * RCU, i.e. access to the list and hash table is protected by RCU.
+ *
+ * Upon allocating a STA info structure with sta_info_alloc(), the caller owns
+ * that structure. It must then either destroy it using sta_info_destroy()
+ * (which is pretty useless) or insert it into the hash table using
+ * sta_info_insert() which demotes the reference from ownership to a regular
+ * RCU-protected reference; if the function is called without protection by an
+ * RCU critical section the reference is instantly invalidated. Note that the
+ * caller may not do much with the STA info before inserting it, in particular,
+ * it may not start any mesh peer link management or add encryption keys.
+ *
+ * When the insertion fails (sta_info_insert()) returns non-zero), the
+ * structure will have been freed by sta_info_insert()!
+ *
+ * Because there are debugfs entries for each station, and adding those
+ * must be able to sleep, it is also possible to "pin" a station entry,
+ * that means it can be removed from the hash table but not be freed.
+ * See the comment in __sta_info_unlink() for more information, this is
+ * an internal capability only.
+ *
+ * In order to remove a STA info structure, the caller needs to first
+ * unlink it (sta_info_unlink()) from the list and hash tables and
+ * then destroy it; sta_info_destroy() will wait for an RCU grace period
+ * to elapse before actually freeing it. Due to the pinning and the
+ * possibility of multiple callers trying to remove the same STA info at
+ * the same time, sta_info_unlink() can clear the STA info pointer it is
+ * passed to indicate that the STA info is owned by somebody else now.
+ *
+ * If sta_info_unlink() did not clear the pointer then the caller owns
+ * the STA info structure now and is responsible of destroying it with
+ * a call to sta_info_destroy().
+ *
+ * In all other cases, there is no concept of ownership on a STA entry,
+ * each structure is owned by the global hash table/list until it is
+ * removed. All users of the structure need to be RCU protected so that
+ * the structure won't be freed before they are done using it.

/*
- * sock_lock(): Lock a port/socket pair. lock_sock() can
- * not be used here, since the same lock must protect ports
- * with non-socket interfaces.
- * See net.c for description of locking policy.
+ * Revised TIPC socket locking policy:
+ *
+ * Most socket operations take the standard socket lock when they start
+ * and hold it until they finish (or until they need to sleep). Acquiring
+ * this lock grants the owner exclusive access to the fields of the socket
+ * data structures, with the exception of the backlog queue. A few socket
+ * operations can be done without taking the socket lock because they only
+ * read socket information that never changes during the life of the socket.
+ *
+ * Socket operations may acquire the lock for the associated TIPC port if they
+ * need to perform an operation on the port. If any routine needs to acquire
+ * both the socket lock and the port lock it must take the socket lock first
+ * to avoid the risk of deadlock.
+ *
+ * The dispatcher handling incoming messages cannot grab the socket lock in
+ * the standard fashion, since invoked it runs at the BH level and cannot block.
+ * Instead, it checks to see if the socket lock is currently owned by someone,
+ * and either handles the message itself or adds it to the socket's backlog
+ * queue; in the latter case the queued message is processed once the process
+ * owning the socket lock releases it.
+ *
+ * NOTE: Releasing the socket lock while an operation is sleeping overcomes
+ * the problem of a blocked socket operation preventing any other operations
+ * from occurring. However, applications must be careful if they have
+ * multiple threads trying to send (or receive) on the same socket, as these
+ * operations might interfere with each other. For example, doing a connect
+ * and a receive at the same time might allow the receive to consume the
+ * ACK message meant for the connect. While additional work could be done
+ * to try and overcome this, it doesn't seem to be worthwhile at the present.
+ *
+ * NOTE: Releasing the socket lock while an operation is sleeping also ensures
+ * that another operation that must be performed in a non-blocking manner is
+ * not delayed for very long because the lock has already been taken.
+ *
+ * NOTE: This code assumes that certain fields of a port/socket pair are
+ * constant over its lifetime; such fields can be examined without taking
+ * the socket lock and/or port lock, and do not need to be re-read even
+ * after resuming processing after waiting. These fields include:
+ * - socket type
+ * - pointer to socket sk structure (aka tipc_sock structure)
+ * - pointer to port structure
+ * - port reference

+ *
+ * For now, drivers can restrict the set of allowed channels by either
+ * not registering those channels or setting the IEEE80211_CHAN_DISABLED
+ * flag; that flag will only be *set* by this code, never *cleared.
+ *
+ * The usual implementation is for a driver to read a device EEPROM to
+ * determine which regulatory domain it should be operating under, then
+ * looking up the allowable channels in a driver-local table and finally
+ * registering those channels in the wiphy structure.
+ *
+ * Alternatively, drivers that trust the regulatory domain control here
+ * will register a complete set of capabilities and the control code
+ * will restrict the set by setting the IEEE80211_CHAN_* flags.
