2012-09-07ARM: 7526/1: traps: send SIGILL if get_user fails on undef handling pathWill Deacon
get_user may fail to load from the provided __user address due to an unhandled fault generated by the access. In the case of the undefined instruction trap, this results in failure to load the faulting instruction, in which case we should send SIGILL to the task rather than continue with potentially uninitialised data.

2012-09-07ath9k: Fix TX filter usageSujith Manoharan
The TX filter bit for a station would be set by the HW when a frame is not acked. A frame would be completed with ATH9K_TXERR_FILT status only when the corresponding filter bit for the destination station is already set. Currently, un-acknowledged packets are added to the pending queue and retried, but the "clear_dest_mask" bit in the descriptor is set only when the TX status has been ATH9K_TXERR_FILT. This results in packet loss and the log shows: wlan0: dropped TX filtered frame, queue_len=0 PS=0 @4309746071 wlan0: dropped TX filtered frame, queue_len=0 PS=0 @4309746076 wlan0: dropped TX filtered frame, queue_len=0 PS=0 @4309746377 ... ... This issue can be resolved by making sure that the destination mask is cleared when the packet is being retried and the earlier TX status is ATH9K_TXERR_XRETRY.

2012-09-07wireless: ath9k-htc: only load firmware in needMing Lei
It is not necessary to hold the firmware memory during the whole driver lifetime, and obviously it does waste memory. Suppose there are 4 ath9k-htc usb dongles working, kernel has to consume about 4*50KBytes RAM to cache firmware for all dongles. After applying the patch, kernel only caches one single firmware image in RAM for all ath9k-htc devices just during system suspend/resume cycle. When system is ready for loading firmware, ath9k-htc can request the loading from usersapce. During system resume, ath9k-htc still can load the firmware which was cached in kernel memory before system suspend. Cc: ath9k-devel@lists.ath9k.org Cc: "Luis R.

QMI requests exceeding 1500 bytes are possible and device firmware does not handle fragmented messages very well. It is therefore necessary to increase the maximum message size from the current 512 bytes. The protocol message size limit is not documented in any publicly known source, but the out of tree driver from CodeAurora use 4 kB. This is therefore chosen as the new arbitrary default until the real limit is known. This should allow any QMI message to be transmitted without fragmentation, fixing known issues with GPS assistance data upload. Signed-off-by: Bjørn Mork <bjorn@mork.no> Signed-off-by: David S.

2012-09-07scm: Don't use struct ucred in NETLINK_CB and struct scm_cookie.Eric W. Biederman
Passing uids and gids on NETLINK_CB from a process in one user namespace to a process in another user namespace can result in the wrong uid or gid being presented to userspace. Avoid that problem by passing kuids and kgids instead. - define struct scm_creds for use in scm_cookie and netlink_skb_parms that holds uid and gid information in kuid_t and kgid_t. - Modify scm_set_cred to fill out scm_creds by heand instead of using cred_to_ucred to fill out struct ucred. This conversion ensures userspace does not get incorrect uid or gid values to look at. - Modify scm_recv to convert from struct scm_creds to struct ucred before copying credential values to userspace. - Modify __scm_send to populate struct scm_creds on in the scm_cookie, instead of just copying struct ucred from userspace. - Modify netlink_sendmsg to copy scm_creds instead of struct ucred into the NETLINK_CB.

There are two btusb patches to add more supported devices through the new USB_VENDOR_AND_INTEFACE_INFO() macro and another one that add a new device id for a Sony Vaio laptop, one fix for a user-after-free and, finally, two patches from Vinicius to fix a issue in SMP pairing." Along with those... Arend van Spriel provides a fix for a use-after-free bug in brcmfmac. Daniel Drake avoids a hang by not trying to touch the libertas hardware duing suspend if it is already powered-down. Felix Fietkau provides a batch of ath9k fixes that adress some potential problems with power settings, as well as a fix to avoid a potential interrupt storm. Gertjan van Wingerde provides a register-width fix for rt2x00, and a rt2x00 fix to prevent incorrectly detecting the rfkill status. He also provides a device ID patch. Hante Meuleman gives us three brcmfmac fixes, one that properly initializes a command structure, one that fixes a race condition that could lose usb requests, and one that removes some log spam. Marc Kleine-Budde offers an rt2x00 fix for a voltage setting on some specific devices. Mohammed Shafi Shajakhan sent an ath9k fix to avoid a crash related to using timers that aren't allocated when 2 wire bluetooth coexistence hardware is in use. Sergei Poselenov changes rt2800usb to do some validity checking for received packets, avoiding crashes on an ARM Soc. Stone Piao gives us an mwifiex fix for an incorrectly set skb length value for a command buffer. All of these are localized to their specific drivers, and relatively small. The power-related patches from Felix are bigger than I would like, but I merged them in consideration of their isolation to ath9k and the sensitive nature of power settings in wireless devices. ==================== Signed-off-by: David S.

2012-09-07ipv6: fix handling of throw routesNicolas Dichtel
It's the same problem that previous fix about blackhole and prohibit routes. When adding a throw route, it was handled like a classic route. Moreover, it was only possible to add this kind of routes by specifying an interface. Before the patch: $ ip route add throw 2001::2/128 RTNETLINK answers: No such device $ ip route add throw 2001::2/128 dev eth0 $ ip -6 route | grep 2001::2 2001::2 dev eth0 metric 1024 After: $ ip route add throw 2001::2/128 $ ip -6 route | grep 2001::2 throw 2001::2 dev lo metric 1024 error -11 Reported-by: Markus Stenberg <markus.stenberg@iki.fi> Signed-off-by: Nicolas Dichtel <nicolas.dichtel@6wind.com> Acked-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.
