f20531a | Oussama Ghorbel | 04 November 2014, 06:17:06 UTC | phy: omap-usb2: Enable runtime PM of omap-usb2 phy properly The USB OTG port does not work since v3.16 on omap platform. This is a regression introduced by the commit eb82a3d846fa (phy: omap-usb2: Balance pm_runtime_enable() on probe failure and remove). This because the call to pm_runtime_enable() function is moved after the call to devm_phy_create() function, which has side effect since later in the subsequent calls of devm_phy_create() there is a check with pm_runtime_enabled() to configure few things.

This commit also fixes one bug found at below situation: we have not enabled usb wakeup, we do system suspend when there is an usb device at the port, after suspend, we plug out the usb device, then plug in device again. At that time, the nofity disconnect was not called at current code, as the controller doesn't know the usb device was disconnected during the suspend, but USB core knows the port has changed during that periods. So to fix this problem, and let the usb core call notify disconnect.

An uas capable Seagate disk which is known to work fine with other controllers causes the system to freeze when connected over usb-3 with this controller, where as it works fine with uas in usb-2 ports, indicating a problem with streams. This is a bit bigger hammer then I would like to use for this, but for now it will have to make do. I've ordered a pci-e usb controller card with an Asmedia 1042, once that arrives I'll try to get streams to work (with a quirk flag if necessary) and then we can re-enable them. For now this at least makes uas capable disk enclosures work again by forcing fallback to the usb-storage driver.

93c9bf4 | Alan Stern | 31 October 2014, 18:49:47 UTC | usb-storage: handle a skipped data phase Sometimes mass-storage devices using the Bulk-only transport will mistakenly skip the data phase of a command. Rather than sending the data expected by the host or sending a zero-length packet, they go directly to the status phase and send the CSW. This causes problems for usb-storage, for obvious reasons. The driver will interpret the CSW as a short data transfer and will wait to receive a CSW. The device won't have anything left to send, so the command eventually times out. The SCSI layer doesn't retry commands after they time out (this is a relatively recent change). Therefore we should do our best to detect a skipped data phase and handle it promptly. This patch adds code to do that. If usb-storage receives a short 13-byte data transfer from the device, and if the first four bytes of the data match the CSW signature, the driver will set the residue to the full transfer length and interpret the data as a CSW. This fixes Bugzilla #86611.

282da87 | Jan Kiszka | 08 October 2014, 16:05:39 UTC | KVM: nVMX: Disable preemption while reading from shadow VMCS In order to access the shadow VMCS, we need to load it. At this point, vmx->loaded_vmcs->vmcs and the actually loaded one start to differ. If we now get preempted by Linux, vmx_vcpu_put and, on return, the vmx_vcpu_load will work against the wrong vmcs. That can cause copy_shadow_to_vmcs12 to corrupt the vmcs12 state. Fix the issue by disabling preemption during the copy operation. copy_vmcs12_to_shadow is safe from this issue as it is executed by vmx_vcpu_run when preemption is already disabled before vmentry. This bug is exposed by running Jailhouse within KVM on CPUs with shadow VMCS support. Jailhouse never expects an interrupt pending vmexit, but the bug can cause it if, after copy_shadow_to_vmcs12 is preempted, the active VMCS happens to have the virtual interrupt pending flag set in the CPU-based execution controls.

Related to this, when enabling IFF_PROMISC in switch mode, all registered multicast addresses are flushed, resulting in only broadcast and unicast traffic being received. A new cpsw_ale_set_allmulti function now scans through the ALE entry table and adds/removes the host port from the unregistered multicast port mask of each vlan entry depending on the state of IFF_ALLMULTI. In promiscious mode, cpsw_ale_set_allmulti is used to force reception of all multicast traffic in addition to the unicast and broadcast traffic. With this change dynamic multicast and promiscious mode both work in switch mode. Signed-off-by: Len Sorensen <lsorense@csclub.uwaterloo.ca> Signed-off-by: David S.

It was correct to fix the dual_emac mode section since there 'i' is used as an index into priv->slaves which is a 0 based array. However the other two changes (which are only used in switch mode) are wrong since there 'i' is actually the ALE port number, and port 0 is the host port, while port 1 and up are the slave ports. Putting the loop condition back in the switch mode section fixes it. A comment has been added to point out the intent clearly to avoid future confusion.

The patches are: 1) Fix a null-pointer dereference that may occur when logging errors. This problem was introduced by 4a4739d56b0 ("ipvs: Pull out crosses_local_route_boundary logic") in v3.17-rc5. 2) Update hook mask in nft_reject_bridge so we can also filter out packets from there. This fixes 36d2af5 ("netfilter: nf_tables: allow to filter from prerouting and postrouting"), which needs this chunk to work. 3) Two patches to refactor common code to forge the IPv4 and IPv6 reject packets from the bridge. These are required by the nf_tables reject bridge fix. 4) Fix nft_reject_bridge by avoiding the use of the IP stack to reject packets from the bridge. The idea is to forge the reject packets and inject them to the original port via br_deliver() which is now exported for that purpose. 5) Restrict nft_reject_bridge to bridge prerouting and input hooks. the original skbuff may cloned after prerouting when the bridge stack needs to flood it to several bridge ports, it is too late to reject the traffic. ==================== Signed-off-by: David S.

523b929 | Pablo Neira Ayuso | 25 October 2014, 16:40:26 UTC | netfilter: nft_reject_bridge: don't use IP stack to reject traffic If the packet is received via the bridge stack, this cannot reject packets from the IP stack. This adds functions to build the reject packet and send it from the bridge stack. Comments and assumptions on this patch: 1) Validate the IPv4 and IPv6 headers before further processing, given that the packet comes from the bridge stack, we cannot assume they are clean. Truncated packets are dropped, we follow similar approach in the existing iptables match/target extensions that need to inspect layer 4 headers that is not available. This also includes packets that are directed to multicast and broadcast ethernet addresses. 2) br_deliver() is exported to inject the reject packet via bridge localout -> postrouting. So the approach is similar to what we already do in the iptables reject target. The reject packet is sent to the bridge port from which we have received the original packet. 3) The reject packet is forged based on the original packet. The TTL is set based on sysctl_ip_default_ttl for IPv4 and per-net ipv6.devconf_all hoplimit for IPv6. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> | 31 October 2014, 11:50:08 UTC |

b2de525 | David Jeffery | 29 September 2014, 14:21:10 UTC | Return short read or 0 at end of a raw device, not EIO Author: David Jeffery <djeffery@redhat.com> Changes to the basic direct I/O code have broken the raw driver when reading to the end of a raw device. Instead of returning a short read for a read that extends partially beyond the device's end or 0 when at the end of the device, these reads now return EIO. The raw driver needs the same end of device handling as was added for normal block devices. Using blkdev_read_iter, which has the needed size checks, prevents the EIO conditions at the end of the device.

UFO for IPv6 requires the ID to be passed separately, but there is no provision for this in the virtio net protocol. Until recently our software implementation of UFO/IPv6 generated a new ID, but this was a bug. Now we will use ID=0 for any UFO/IPv6 packet passed through a tap, which is even worse. Unfortunately there is no distinction between UFO/IPv4 and v6 features, so disable UFO on taps and virtio_net completely until we have a proper solution. We cannot depend on VM managers respecting the tap feature flags, so keep accepting UFO packets but log a warning the first time we do this.
