This patch (as1344) removes references to port->port.count from the USB serial drivers. Now that serial ports are properly reference counted, port.count checking is unnecessary and incorrect. Drivers should assume that the port is in use from the time the open method runs until the close method is called.

I've got a crappy cypress converter here, and while running at higher baud rates craps out on throughput, it works fine with lower ones. While it'd be nice to simply use a lower baud rate, not all devices can be configured this way, and it is possible to (slowly) interact at higher rates by sending a byte at a time. So let people force higher rates when they need it via a module parameter. Signed-off-by: NMike Frysinger <vapier@gentoo.org> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

many serial subdrivers are clearly written as if throttle/unthrottle cannot sleep. This leads to unneeded atomic submissions. This patch converts affected drivers in a way to makes very clear that throttle/unthrottle can sleep. Thus future misdesigns can be avoided and efficiency and reliability improved.

This patch (as1265) removes an erroneous call to usb_clear_halt from the cypress_m8 driver. The call isn't valid because it is made from interrupt context whereas usb_clear_halt is a blocking routine. Presumably the code has never been executed; if it did it would cause an oops. So instead treat -EPIPE like any other sort of unexplained error. Signed-off-by: NAlan Stern <stern@rowland.harvard.edu> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>

This patch (as1254) splits up the shutdown method of usb_serial_driver into a disconnect and a release method. The problem is that the usb-serial core was calling shutdown during disconnect handling, but drivers didn't expect it to be called until after all the open file references had been closed. The result was an oops when the close method tried to use memory that had been deallocated by shutdown.

Use kref in the USB serial drivers so that we don't free tty structures from under the URB receive handlers as has historically been the case if you were unlucky.

USB serial likes to use port->tty back pointers for the real work it does and to do so without any actual locking. Unfortunately when you consider hangup events, hangup/parallel reopen or even worse hangup followed by parallel close events the tty->port and port->tty pointers are not guaranteed to be the same as port->tty is the active tty while tty->port is the port the tty may or may not still be attached to. So rework the entire API to pass the tty struct. For console cases we need to pass both for now. This shows up multiple drivers that immediately crash with USB console some of which have been fixed in the process. Longer term we need a proper tty as console abstraction Signed-off-by: NAlan Cox <alan@redhat.com> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

The cypress app note for the M8 states that for the USB low speed version of the part, throughput is effectively limited to 800 bytes/sec. So if we were to try a faster baud rate in such cases then we risk overrun errors on receive. Best to just identify this case and limit the rate to 4800 baud or less (by ignoring any request to set a faster rate). The old baud rate setting code was somewhat fragile; this change also hopefully makes it easier in the future to better checking / limiting.

Remove a NULL check in cypress_m8; the check is useless in this context because it is referenced earlier in the same code path thus the kernel would be oops'ed before reaching this point anyway.

cypress_m8: Packet format is separate from characteristic size The Cypress app note states that when using an 8 byte packet buffer size that the packet format is modified (to be more compact). However I have since discovered that newer DeLorme Earthmate LT-20 devices (those that are low speed USB with 8 byte packet size) STILL use the format that is really supposed to correspond to 32 byte packets. Further confusing things is the subsequent discovery that there are actually two different types of LT-20 - older LT-20's use 32 byte packets which is probably why this issue wasn't originally encountered. The solution here is to flag the packet format separately from the buffer size. Then at initialization time, identify the correct combination and set it up. This is a critical fix for anyone with a newer LT-20. Older devices and non-Earthmate devices should remain unaffected by this change. (If other devices behave in this, uh, unexpected manner, it's now just a simple 1 line change to fix them as well (change the pkt_fmt member for that device). Default behavior with this patch is still to drive the format as per the app-note; of course for Earthmate devices this is overridden.

cypress_m8: Feature buffer fixes From: Mike Isely <isely@pobox.com> Don't hardcode the feature buffer size; use sizeof() instead. That way we can easily specify the size in a single spot.

this driver uses usb_get_intfdata() == NULL as a test for disconnect(). You must not do that as this races with probe(). By the time you test your erstwhile interface may already be somebody else's interface. This fixes the close() method of cypress_m8 to use the recently introduced flag and use locking against disconnect() where required in close().
