* sierra: driver interface blacklistingElina Pasheva2009-06-11
| | | | | | | | | | | | | | | | | | | | | | Interface blacklisting is necessary for non-serial interfaces that are handled by a different driver. The interface blacklisting is implemented in sierra driver per device. Each device in need of a blacklist has a static information array kept in the driver. This array contains the interface numbers that are blacklisted. The pointer for each blacklist array and the length of that blacklist are 'bundled' in data structure sierra_iface_info. A pointer to this information is set in id_table when the device is added to the id_table. The following is summary of changes we have made to sierra.c driver in this patch dealing with interface blacklisting support: - Added data structure sierra_iface_info and function is_blacklisted() to support blacklisting - Modified sierra_probe() to handle blacklisted interfaces accordingly - Improved comments in id_table - Added new device in id_table with blacklist interface support Signed-off-by: Elina Pasheva <epasheva@sierrawireless.com> Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* sierra: driver urb handling improvementsElina Pasheva2009-06-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [Folded from eight patches into one as the original set according to the author "All of the patches need to be applied to obtain a working product" so keeping them split seems unhelpful Merge fixes done versus other conflicting changes and moved the spin_lock_init from open to setup time -- Alan] Summary of the changes and code re-organization in this patch: - The memory for urbs is allocated and urbs are submitted only for the active interfaces (instead of pre-allocating these for all interfaces). This will save memory especially in the case of using composite devices. - The code has been re-organized and functionality has been extracted from sierra_startup(), sierra_shutdown(), sierra_open(), sierra_close() and added in helper functions sierra_release_urb(), sierra_stop_rx_urbs(), sierra_submit_rx_urbs() and sierra_setup_urb() - Added function sierra_release_urb() to free an urb and its transfer buffer. - Removed unecessary include file reference and comment. - Added function sierra_stop_rx_urbs() that takes care of the release of receive and interrupt urbs. This function is to be called by sierra_close() whenever an interface is de-activated. - Added new function sierra_submit_rx_urbs() that handles the submission of receive urbs and interrupt urbs (if any) during the interface activation. This function is to be called by sierra_open(). Added a second parameter to pass the memory allocation (as suggested by Oliver Neukum) so that this function can be used in post_reset() and resume(). - Added new function sierra_setup_urb() that contains the functionality to allocate an urb, fill bulk urb using the supplied memory allocation flag and release urb upon error. Added parameter so that the caller pass the memory allocation flag for flexibility. - Moved sierra_close() before sierra_open() to resolve dependencies introduced by the code reorganization. - Modified sierra_close() to call sierra_stop_rx_urbs() and sierra_release_urb() functions added in previous patch. - Modified sierra_open() to call sierra_setup_urb() and sierra_submit_rx_urbs() functions; note urbs are allocated and submitted for each activated interface. - Modified sierra_startup() so that allocation of urbs happens whenever an interface is activated (urb allocation is moved to sierra_open()). - Modified sierra_shutdown() so that urbs are freed whenever an interface is de-activated (urb freeing moved to sierra_close() as shown in previous patch from the series) - Removed unecessary data structure from sierra_port_private_data - Suppress an entry in logs by not re-submitting an urb when usb_submit_urb() returns -EPERM, as this shows that usb_kill_urb() is running (as suggested by Oliver Neukum) Signed-off-by: Elina Pasheva <epasheva@sierrawireless.com> Signed-off-by: Alan Cox <alan.cox@linux.intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* tty: rewrite the ldisc lockingAlan Cox2009-06-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are several pretty much unfixable races in the old ldisc code, especially with respect to pty behaviour and also to hangup. It's easier to rewrite the code than simply try and patch it up. This patch - splits the ldisc from the tty (so we will be able to refcount it more cleanly later) - introduces a mutex lock for ldisc changing on an active device - fixes the complete mess that hangup caused - implements hopefully correct setldisc/close/hangup locking There are still some problems around pty pairs that have always been there but at least it is now possible to understand the code and fix further problems. This fixes the following known bugs - hang up can leak ldisc references - hang up may not call open/close on ldisc in a matched way - pty/tty pairs can deadlock during an ldisc change - reading the ldisc proc files can cause every ldisc to be loaded and probably a few other of the mysterious ldisc race reports.

* tty: throttling race fixAlan Cox2009-06-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The tty throttling code can race due to the lock drops. It takes very high loads but this has been observed and verified by Rob Duncan. The basic problem is that on an SMP box we can go CPU #1 CPU #2 need to throttle ? suppose we should buffer space cleared are we throttled yes ? - unthrottle call throttle method This changeet take the termios lock to protect against this. The termios lock isn't the initial obvious candidate but many implementations of throttle methods already need to poke around their own termios structures (and nobody really locks them against a racing change of flow control). This does mean that anyone who is setting tty->low_latency = 1 and then calling tty_flip_buffer_push from their unthrottle method is going to end up collapsing in a pile of locks. However we've removed all the known bogus users of low_latency = 1 and such use isn't safe anyway for other reasons so catching it would be an improvement.
