2007-08-22usb quirks: Add Canon EOS 5D (PC Connection mode) to the autosuspend blacklistPaul Walmsley
Recent versions of the Linux kernel auto-suspend attached USB devices. After this happens to the Canon EOS 5D camera, the camera's interrupt endpoints don't seem to wake back up correctly, causing further use with libgphoto2 to fail with a -114 "OS error in camera communication" error. A similar fix is probably necessary for this camera in PTP mode, which identifies as USB product id 0x3102, but we haven't tested this. As part of our testing process, we tried the USB_QUIRK_RESET_RESUME quirk also, it's not helpful in this case.

Correctly initialize the on-chip EHCI controller on the AMCC PPC440EPx. Fix "USB 0.0" initialization message, and properly put the controller into a known state before starting it. Add "FIXME" comment to the au1xxx bus glue which is doing the same wrong thing here. (Who maintains that, now that AMD sold off Alchemy?)

2007-08-22USB: fix DoS in pwc USB video driverOliver Neukum
the pwc driver has a disconnect method that waits for user space to close the device.

2007-08-22usb-storage: fix bugs in the disconnect pathwayAlan Stern
This patch (as961) fixes a couple of bugs in the disconnect pathway of usb-storage. The first problem, which apparently has been around for a while although nobody noticed it, shows up when an aborted command is still pending when a disconnect occurs. The SCSI error-handler will continue to wait in command_abort() until the us->notify completion is signalled. Thus quiesce_and_remove_host() needs to signal it. The second problem was introduced recently along with autosuspend support. Since usb_stor_scan_thread() now calls usb_autopm_put_interface() before exiting, we can't simply leave the scanning thread running after a disconnect; we must wait until the thread exits. This is solved by adding a new struct completion to the private data structure. Fortuitously, it allows the removal of the rather clunky mechanism used in the past to insure that all threads have finished before the module is unloaded.

2007-08-22USB: accept 1-byte Device Status replies, fixing some b0rken devicesAlan Stern
Some devices have a bug which causes them to send a 1-byte reply to Get-Device-Status requests instead of 2 bytes as required by the spec. This doesn't play well with autosuspend, since we look for a valid status reply to make sure the device is still present when it resumes. Without both bytes, we assume the device has been disconnected. Lack of the second byte shouldn't matter much, since the spec requires it always to be equal to 0. Hence this patch (as959) causes finish_port_resume() to accept a 1-byte reply as valid.

If, in em28xx_usb_probe() the memory allocation dev->alt_max_pkt_size = kmalloc(32* dev->num_alt,GFP_KERNEL); fails, then we'll bail out and return -ENOMEM.

2007-08-22USB: serial: garmin_gps: fixes package loss if used from gpsbabelHermann Kneissel
This patch contains two fixes submitted by Ondrej Palkovsky: - the 'ACK' packet is sent after the transfer of the USB packet is completed, i.e. in the write_callback function. Because the close function sends the 'abort' command, a parameter is added that allows the caller of garmin_write_bulk to specify, if the 'ack' should be propagated to the serial link or dimissed. This fixes the problem with gpsbabel, it has sent several packets that were acknowledged before they were sent to the GPS and GpsBabel closed the device - thus effectively cancelled all outstanding requests in the queue. - removed the APP_RESP_SEEN and APP_REQ_SEEN flags and changed them into counters.

2007-08-22[S390] kprobes: fix instruction length calculationDavid Wilder
Placing a kprobe on "bc" instruction (s390/s390x) can cause an oops. The instruction length is encoded into the first two bits of the s390 instruction. Kprobe is incorrectly computing the instruction length. The instruction length is used for determining what type of "fix-up" is needed for conditional branch instruction. The problem can bee seen by placing a kprobe on a "bc" instruction that will not branch. The results is that Kprobe incorrectly computes the new instruction pointer (psw.addr) after single stepping the instruction. The problem is corrected with this patch.

2007-08-22[S390] hypfs: inode corruption due to missing lockingMichael Holzheu
hypfs removes the whole hypfs directory tree and creates a new one, when a process triggers an update by writing to the "update" attribute. When removing and creating files, it is necessary to lock the inode of the parent directory where the files live. Currently hypfs does not lock the parent inode, which can lead to inode corruption. This patch: * Introduces correct locking * Fixes i_nlink reference counting for inodes, when creating directories * Adds info printk, when hypfs filesystem has been mounted Signed-off-by: Michael Holzheu <holzheu@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com> Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>
2007-08-22[S390] disassembler: fix b2 opcodes like srst, bsg, and othersChristian Borntraeger
The instruction table for b2 opcodes was missing an opfrag value for the cpya instruction. All instructions specified after cpya were not considered by the disassembler. The fix is simple and obvious - add the opfrag field to the cpya instruction.

2007-08-22[S390] vmur: fix reference counting for vmur device structureMichael Holzheu
When a vmur device is removed due to a detach of the device, currently the ur device structure is freed. Unfortunately it can happen, that there is still a user of the device structure, when the character device is open during the detach process. To fix this, reference counting for the vmur structure is introduced. In addition to that, the online, offline, probe and remove functions are serialized now using a global mutex.

2007-08-22[S390] vmur: fix diag14 exceptions with addresses > 2GB.Michael Holzheu
There are several s390 diagnose calls, which must be executed below the 2GB memory boundary. In order to enforce this, those diagnoses must be compiled into the kernel. Currently diag 14 can be called within the vmur kernel module from addresses above 2GB. This leads to specification exceptions. This patch moves diag10, diag14 and diag210 into the new diag.c file.

2007-08-22[S390] qdio: Refresh buffer states for IQDIO Asynchronous output queueKlaus D. Wacker
Hipersocket Multicast queue works asynchronously. When sending buffers, the buffer state change may happen delayed. The tasklet for checking changes in the outbound queue excluded IQDIO async queues from this process. This created either a hang situation when the queue ran full, or presented a hang situation a interface close time. The tasklet processing is changed to include IQDIO async queues when requesting buffer state refresh. Signed-off-by: Klaus D.

2007-08-22[S390] qdio: fix EQBS handling on CCQ96Klaus D. Wacker
QDIO returned from EQBS instruction in any case after return code CCQ=96 was issued regardless whether buffer states for at least one buffer were extracted or not. This caused FCP devices to hang when running under z/VM and having QIOASSASIST=ON and having high I/O rates. In order to fix this qdio return code processing of EQBS instruction after CCQ=96 is changed that buffers are returned and if no buffers where extracted the instruction is repeated at once.

2007-08-22[S390] cio: change confusing message in cmf.Cornelia Huck
cmf currently prints a message that more than 4096 channels are not allowed in basic mode - however, this can only be enforced if cmf was a module (which is no longer possible). It makes much more sense to not check the specified number of channels and just print a message if the block for basic mode could not be allocated (which may happen for any number of specified channels).
