commit b4203ff5 upstream. Plantronics BT300 does not support reading the sample rate which leads to many lines of "cannot get freq at ep 0x1". This patch adds the USB ID of the BT300 to quirks.c and avoids those error messages. Signed-off-by:

commit 4f4bc0ab upstream. There is a typo in documentation regarding to descriptor empty bit (DESCE) which is set to 1 when descriptor is empty. Thus, status register at the end of a transfer usually returns all DESCE bits set and thus it will never be zero. Moreover, there are 2 bits (CDESC) that encode current descriptor, on which interrupt has been asserted. In case when we have few descriptors programmed we might have non-zero value. Remove DESCE and CDESC bits from DMA channel status register (HSU_CH_SR) when reading it. Fixes: 2b49e0c5 ("dmaengine: append hsu DMA driver") Signed-off-by:

commit 162f98de upstream. The gtco driver expects at least one valid endpoint. If given malicious descriptors that specify 0 for the number of endpoints, it will crash in the probe function. Ensure there is at least one endpoint on the interface before using it. Also let's fix a minor coding style issue.

commit d59a1f71 upstream. The SPICE protocol considers the position of a cursor to be the location of its active pixel on the display, so the cursor is drawn with its top-left corner at "(x - hot_spot_x, y - hot_spot_y)" but the DRM cursor position gives the location where the top-left corner should be drawn, with the hotspot being a hint for drivers that need it. This fixes the location of the window resize cursors when using Fluxbox with the QXL DRM driver and both the QXL and modesetting X drivers. Signed-off-by:

commit 3ca4a238 upstream. Commit 127500cc ("ARM: OMAP2+: Only write the sysconfig on idle when necessary") talks about verification of sysconfig cache value before updating it, only during idle path. But the patch is adding the verification in the enable path. So, adding the check in a proper place as per the commit description. Not keeping this check during enable path as there is a chance of losing context and it is safe to do on idle as the context of the register will never be lost while the device is active.

commit 972e6a99 upstream. The usbhid driver has inconsistently duplicated code in its post-reset, resume, and reset-resume pathways. reset-resume doesn't check HID_STARTED before trying to restart the I/O queues. resume fails to clear the HID_SUSPENDED flag if HID_STARTED isn't set. resume calls usbhid_restart_queues() with usbhid->lock held and the others call it without holding the lock. The first item in particular causes a problem following a reset-resume if the driver hasn't started up its I/O. URB submission fails because usbhid->urbin is NULL, and this triggers an unending reset-retry loop. This patch fixes the problem by creating a new subroutine, hid_restart_io(), to carry out all the common activities. It also adds some checks that were missing in the original code: After a reset, there's no need to clear any halted endpoints. After a resume, if a reset is pending there's no need to restart any I/O until the reset is finished. After a resume, if the interrupt-IN endpoint is halted there's no need to submit the input URB until the halt has been cleared. Signed-off-by:

Since the fix in f91ff5b9 ("net: sk_{detach|attach}_filter() rcu fixes") sk_attach_filter()/sk_detach_filter() now dereferences the filter with rcu_dereference_protected(), checking whether socket lock is held in control path. Since its introduction in 99405162 ("tun: socket filter support"), tap filters are managed under RTNL lock from __tun_chr_ioctl(). Thus the sock_owned_by_user(sk) doesn't apply in this specific case and therefore triggers the false positive. Extend the BPF API with __sk_attach_filter()/__sk_detach_filter() pair that is used by tap filters and pass in lockdep_rtnl_is_held() for the rcu_dereference_protected() checks instead. Reported-by:

[ Upstream commit fe30937b ] bond_get_stats() can be called from rtnetlink (with RTNL held) or from /proc/net/dev seq handler (with RCU held) The logic added in commit 5f0c5f73 ("bonding: make global bonding stats more reliable") kind of assumed only one cpu could run there. If multiple threads are reading /proc/net/dev, stats can be really messed up after a while. A second problem is that some fields are 32bit, so we need to properly handle the wrap around problem. Given that RTNL is not always held, we need to use bond_for_each_slave_rcu(). Fixes: 5f0c5f73 ("bonding: make global bonding stats more reliable") Signed-off-by:

Note that the socket's encap_rcv hook still needs to return a negative value to request dispatch, and in the case of IPv6 packets, adjust IP6CB(skb)->nhoff to identify the byte containing the next protocol.

[ Upstream commit 5146d1f1 ] IPCB may contain data from previous layers (in the observed case the qdisc layer). In the observed scenario, the data was misinterpreted as ip header options, which later caused the ihl to be set to an invalid value (<5). This resulted in an infinite loop in the mips implementation of ip_fast_csum. This patch clears IPCB(skb)->opt before dst_link_failure can be called for various types of tunnels. This change only applies to encapsulated ipv4 packets. The code introduced in 11c21a30 which clears all of IPCB has been removed to be consistent with these changes, and instead the opt field is cleared unconditionally in ip_tunnel_xmit. The change in ip_tunnel_xmit applies to SIT, GRE, and IPIP tunnels. The relevant vti, l2tp, and pptp functions already contain similar code for clearing the IPCB. Signed-off-by:

commit 9eb13f65 upstream. This removes the dependency on GPIOLIB for non faulty PHYs. Indeed, without this patch, if GPIOLIB is not selected devm_gpiod_get_optional() will return -ENOSYS and the driver probe call will fail, regardless of the actual PHY hardware. Out of the 3 PHYs supported by this driver (AT8030, AT8031, AT8035), only AT8030 presents the issues that commit 13a56b44 ("net: phy: at803x: Add support for hardware reset") attempts to work-around by using a 'reset' GPIO line. Hence, only AT8030 should depend on GPIOLIB operating properly. Fixes: 13a56b44 ("net: phy: at803x: Add support for hardware reset") Signed-off-by:

commit a6139b62 upstream. This patch corrects the error case in association path by returning -1. Earlier "media_connected" used to remain on in this error case causing failure for further association attempts. Signed-off-by:

commit e17dc653 upstream. Jiri reported some time ago that some entries in the PEBS data source table in perf do not agree with the SDM. We investigated and the bits changed for Sandy Bridge, but the SDM was not updated. perf already implements the bits correctly for Sandy Bridge and later. This patch patches it up for Nehalem and Westmere. Signed-off-by:

commit 21b81716 upstream. Commit d63c7dd5 ("ipr: Fix out-of-bounds null overwrite") removed the end of line handling when storing the update_fw sysfs attribute. This changed the userpace API because it started refusing writes terminated by a line feed, which broke the update tools we already have. This patch re-adds that handling, so both a write terminated by a line feed or not can make it through with the update. Fixes: d63c7dd5 ("ipr: Fix out-of-bounds null overwrite") Signed-off-by:

commit d63c7dd5 upstream. Return value of snprintf is not bound by size value, 2nd argument. (https://www.kernel.org/doc/htmldocs/kernel-api/API-snprintf.html). Return value is number of printed chars, can be larger than 2nd argument. Therefore, it can write null byte out of bounds ofbuffer. Since snprintf puts null, it does not need to put additional null byte. Signed-off-by:
