staging: quatech_usb2: Potential lost wakeup scenario in TIOCMIWAIT 2011-11-07T20:32:15+00:00 Kautuk Consul consul.kautuk@gmail.com 2011-09-14T03:26:21+00:00 705cec330973ff726e5c8421a7c96a7348aa6da0 commit e8df1674d383d2ecc6efa8d7dba74c03aafdfdd7 upstream. If the usermode app does an ioctl over this serial device by using TIOCMIWAIT, then the code will wait by setting the current task state to TASK_INTERRUPTIBLE and then calling schedule(). This will be woken up by the qt2_process_modem_status on URB completion when the port_extra->shadowMSR is set to the new modem status. However, this could result in a lost wakeup scenario due to a race in the logic in the qt2_ioctl(TIOCMIWAIT) loop and the URB completion for new modem status in qt2_process_modem_status. Due to this, the usermode app's task will continue to sleep despite a change in the modem status.

Staging: rtl8192su: Fix procfs code for interfaces not named wlan0 2011-05-09T22:55:09+00:00 Ben Hutchings ben@decadent.org.uk 2010-05-25T03:25:57+00:00 b064372e90da6587a92d855606fc86d1fa58a061 commit 41a38d9e632f7c9ec5ad8fc627567d97f4302c4a upstream. The current code creates directories in procfs named after interfaces, but doesn't handle renaming. This can result in name collisions and consequent WARNINGs. It also means that the interface name cannot reliably be used to remove the directory - in fact the current code doesn't even try, and always uses "wlan0"! Since the name of a proc_dir_entry is embedded in it, use that when removing it. Add a netdev notifier to catch interface renaming, and remove and re-add the directory at this point.
