The command echo "file ec.c +p" >/sys/kernel/debug/dynamic_debug/control causes an oops. Move the call to ddebug_remove_module() down into free_module(). In this way it should be called from all error paths. Currently, we are missing the remove if the module init routine fails. Signed-off-by:

We should use perf_sample_data_init() to initialize struct perf_sample_data. As explained in the description of commit dc1d628a ("perf: Provide generic perf_sample_data initialization"), it is possible for userspace to get the kernel to dereference data.raw, so if it is not initialized, that means that unprivileged userspace can possibly oops the kernel. Using perf_sample_data_init makes sure it gets initialized to NULL. This conversion should have been included in commit dc1d628a, but it got missed. Signed-off-by:

The PCC cpufreq driver unmaps the mailbox address range if any CPUs fail to initialise, but doesn't do anything to remove the registered CPUs from the cpufreq core resulting in failures further down the line. We're better off simply returning a failure - the cpufreq core will unregister us cleanly if we end up with no successfully registered CPUs. Tidy up the failure path and also add a sanity check to ensure that the firmware gives us a realistic frequency - the core deals badly with that being set to 0. Signed-off-by:

The pcc specification documents an _OSC method that's incompatible with the one defined as part of the ACPI spec. This shouldn't be a problem as both are supposed to be guarded with a UUID. Unfortunately approximately nobody (including HP, who wrote this spec) properly check the UUID on entry to the _OSC call. Right now this could result in surprising behaviour if the pcc driver performs an _OSC call on a machine that doesn't implement the pcc specification. Check whether the PCCH method exists first in order to reduce this probability. Signed-off-by:

Eric W. Biederman authored
Recently my tagged sysfs support revealed a flaw in the device core that a few rare drivers are running into such that we don't always put network devices in a class subdirectory named net/. Since we are not creating the class directory the network devices wind up in a non-tagged directory, but the symlinks to the network devices from /sys/class/net are in a tagged directory. All of which works until we go to remove or rename the symlink. When we remove or rename a symlink we look in the namespace of the target of the symlink. Since the target of the symlink is in a non-tagged sysfs directory we don't have a namespace to look in, and we fail to remove the symlink. Detect this problem up front and simply don't create symlinks we won't be able to remove later. This prevents symlink leakage and fails in a much clearer and more understandable way. Signed-off-by:

Commit 0ede76fc, "USB: remove uses of URB_NO_SETUP_DMA_MAP" introduced a regression by inadvertantly removing initialization of the transfer flags. This caused initialization failures in the ums-karma driver. Fix the regression by zeroing it. While at it, as Alan Stern points out, the initializers for actual_length and status are handled by the core and error_count only matters for isochronous urbs, so they don't need to be set here. Remove them. Signed-off-by:

The bmAttributes field of the SuperSpeed Endpoint Companion Descriptor has different meanings, depending on the endpoint type. If the endpoint is isochronous, the bmAttributes field is the maximum number of packets within a service interval that this endpoint supports. If the endpoint is bulk, it's the number of stream IDs this endpoint supports. Only set the Mult field of the xHCI endpoint context using the bmAttributes field if the endpoint is isochronous, and the device is a SuperSpeed device. Signed-off-by:

When an attempt is made to read the interface strings of the Artisman Watchdog USB dongle (idVendor:idProduct 04b4:0526) an error is written to the dmesg log (uhci_result_common: failed with status 440000) and the dongle resets itself, resulting in a disconnect/reconnect loop. Adding the dongle to the list of devices in quirks.c, with the same quirk Alan Stern's previous patch for the Saitek Cyborg Gold 3D joystick, stops the device from resetting and allows it to be used with no problems.

When a configured device is reset, the control endpoint's ring is reused. If control transfers to the device were issued before the device is reset, the dequeue pointer will be somewhere in the middle of the ring. If the device is then issued an address with the set address command, the xHCI driver must provide a valid input context for control endpoint zero. The original code would give the hardware the original input context, which had a dequeue pointer set to the top of the ring. This would cause the host to re-execute any control transfers until it reached the ring's enqueue pointer. When issuing a set address command for a device that has just been configured and then reset, use the control endpoint's enqueue pointer as the hardware's dequeue pointer. Assumption: All control transfers will be completed or cancelled before the set address command is issued to the device. If there are any outstanding control transfers, this code will not work.

Without this fix, a USB 3.0 port is downgraded to full speed after a port reset of a configured device. The USB 3.0 terminations will be disabled permanently, and USB 3.0 devices will always enumerate as full speed devices, until the host controller is unplugged (if it is an ExpressCard) or the computer is rebooted. Fajun Chen traced this traced the speed downgrade issue to the port reset and the interpretation of port status in USB hub driver code. The hub code was not testing for the port being a SuperSpeed port, and it fell through to the else case of Full Speed. The following patch adds SuperSpeed mapping from the port status, and fixes the speed downgrade issue. Reported-by:

Commit 6c12db90 also seems to have introduced a bug that is triggered when the command ring is about to wrap. The inc_enq() function will not have moved the enqueue pointer past the link TRB. It is supposed to be moved past the link TRB in prepare_ring(), which should be called before a TD is enqueued. However, the queue_command() function never calls the prepare_ring() function because prepare_ring() is only supposed to be used for endpoint rings. That means the enqueue pointer will not be moved past the link TRB, and will get overwritten. The fix is to make queue_command() call prepare_ring() with a fake endpoint status (set to running). Then the enqueue pointer will get moved past the link TRB. Signed-off-by:
