* mtd: nand: fix scan_read_raw_oobDmitry Maluka2012-07-03
| | | | | | | | | | | | | | | BugLink: http://bugs.launchpad.net/bugs/1013748 commit 34a5704d91d6f8376a4c0a0143a1dd3eb3ccb37e upstream. It seems there is a bug in scan_read_raw_oob() in nand_bbt.c which should cause wrong functioning of NAND_BBT_SCANALLPAGES option. Artem: the patch did not apply and I had to amend it a bit.

DMA support has finally made its way to the top of the TODO list, having realised that a Geode using MMIO can't keep up with two ADSL2+ lines each running at 21Mb/s. This patch fixes a couple of bugs in the DMA support in the driver, so once the corresponding FPGA update is complete and tested everything should work properly. We weren't storing the currently-transmitting skb, so we were never unmapping it and never freeing/popping it when the TX was done. And the addition of pci_set_master() is fairly self-explanatory.

When BT traffic load changes from its previous state, a new LQ command needs to be sent down to the firmware. This needs to be done only once per change. The state variable that keeps track of this change is last_bt_traffic_load. However, it was not being updated when the change had been handled. Not updating this variable was causing a flood of advanced BT config commands to be sent to the firmware. Fix this.

* SCSI: Fix dm-multipath starvation when scsi host is busyJun'ichi Nomura2012-07-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | BugLink: http://bugs.launchpad.net/bugs/1013748 commit b7e94a1686c5daef4f649f7f4f839cc294f07710 upstream. block congestion control doesn't have any concept of fairness across multiple queues. This means that if SCSI reports the host as busy in the queue congestion control it can result in an unfair starvation situation in dm-mp if there are multiple multipath devices on the same host. For example: http://www.redhat.com/archives/dm-devel/2012-May/msg00123.html The fix for this is to report only the sdev busy state (and ignore the host busy state) in the block congestion control call back. The host is still congested, but the SCSI subsystem will sort out the congestion in a fair way because it knows the relation between the queues and the host.

Apparently debian still uses it so fix it and backport to stable before removing it in 3.6. The breakage is caused because the function template in include/scsi/scsi_scan.h is defined to be a nop unless SCSI is built in.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | BugLink: http://bugs.launchpad.net/bugs/1008697 commit a1e969e0332de7a430e62822cee8f2ec8d83cd7c upstream. This originally started as a patch from Bernard as a way of simply setting the VS scheduler. After submitting the RFC patch, we decided to also modify the DS scheduler. To be most explicit, I've made the patch explicitly set all scheduler modes, and included the defines for other modes (in case someone feels frisky later). The rest of the story gets a bit weird. The first version of the patch showed an almost unbelievable performance improvement. Since rebasing my branch it appears the performance improvement has gone, unfortunately. But setting these bits seem to be the right thing to do given that the docs describe corruption that can occur with the default settings. In summary, I am seeing no more perf improvements (or regressions) in my limited testing, but we believe this should be set to prevent rendering corruption, therefore cc stable. v1: Clear bit 4 also (Ken + Eugeni) Do a full clear + set of the bits we want (Me).

Currently the code re-reads PCH_IIR during the hotplug interrupt processing.

* xhci: Add new short TX quirk for Fresco Logic host.Sarah Sharp2012-06-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | BugLink: http://bugs.launchpad.net/bugs/1008697 commit 1530bbc6272d9da1e39ef8e06190d42c13a02733 upstream. Sergio reported that when he recorded audio from a USB headset mic plugged into the USB 3.0 port on his ASUS N53SV-DH72, the audio sounded "robotic". When plugged into the USB 2.0 port under EHCI on the same laptop, the audio sounded fine. The device is: Bus 002 Device 004: ID 046d:0a0c Logitech, Inc. Clear Chat Comfort USB Headset The problem was tracked down to the Fresco Logic xHCI host controller not correctly reporting short transfers on isochronous IN endpoints. The driver would submit a 96 byte transfer, the device would only send 88 or 90 bytes, and the xHCI host would report the transfer had a "successful" completion code, with an untransferred buffer length of 8 or 6 bytes. The successful completion code and non-zero untransferred length is a contradiction. The xHCI host is supposed to only mark a transfer as successful if all the bytes are transferred. Otherwise, the transfer should be marked with a short packet completion code. Without the EHCI bus trace, we wouldn't know whether the xHCI driver should trust the completion code or the untransferred length. With it, we know to trust the untransferred length. Add a new xHCI quirk for the Fresco Logic host controller. If a transfer is reported as successful, but the untransferred length is non-zero, print a warning. For the Fresco Logic host, change the completion code to COMP_SHORT_TX and process the transfer like a short transfer. This should be backported to stable kernels that contain the commit f5182b4155b9d686c5540a6822486400e34ddd98 "xhci: Disable MSI for some Fresco Logic hosts."

When the xHCI driver needs to clean up memory (perhaps due to a failed register restore on resume from S3 or resume from S4), it needs to reset the number of reserved TRBs on the command ring to zero. Otherwise, several resume cycles (about 30) with a UAS device attached will continually increment the number of reserved TRBs, until all command submissions fail because there isn't enough room on the command ring. This patch should be backported to kernels as old as 2.6.32, that contain the commit 913a8a344ffcaf0b4a586d6662a2c66a7106557d "USB: xhci: Change how xHCI commands are handled."

While testing unplugging an UVC HD webcam with usb-redirection (so through usbdevfs), my userspace usb-redir code was getting a value of -1 in iso_frame_desc[n].status, which according to Documentation/usb/error-codes.txt is not a valid value. The source of this -1 is the default case in xhci-ring.c:process_isoc_td() adding a kprintf there showed the value of trb_comp_code to be COMP_TX_ERR in this case, so this patch adds handling for that completion code to process_isoc_td(). This was observed and tested with the following xhci controller: 1033:0194 NEC Corporation uPD720200 USB 3.0 Host Controller (rev 04) Note: I also wonder if setting frame->status to -1 (-EPERM) is the best we can do, but since I cannot come up with anything better I've left that as is.

Upgraded firmware on Smart Array P7xx (and some others) made them show up as SCSI revision 5 devices and this caused the driver to fail to map MSA2xxx logical drives to the correct bus/target/lun. A symptom of this would be that the target ID of the logical drives as presented by the external storage array is ignored, and all such logical drives are assigned to target zero, differentiated only by LUN. Some multipath software reportedly does not deal well with this behavior, failing to recognize different paths to the same device as such. Signed-off-by: Stephen M.

* SCSI: mpt2sas: Fix for panic happening because of improper memory allocationnagalakshmi.nandigama@lsi.com2012-06-12
| | | | | | | | | | | | | | | | | | | | | | BugLink: http://bugs.launchpad.net/bugs/1008697 commit e42fafc25fa86c61824e8d4c5e7582316415d24f upstream. The ioc->pfacts member in the IOC structure is getting set to zero following a call to _base_get_ioc_facts due to the memset in that routine. So if the ioc->pfacts was read after a host reset, there would be a NULL pointer dereference. The routine _base_get_ioc_facts is called from context of host reset. The problem in _base_get_ioc_facts is the size of Mpi2IOCFactsReply is 64, whereas the sizeof "struct mpt2sas_facts" is 60, so there is a four byte overflow resulting from the memset. Also, there is memset in _base_get_port_facts using the incorrect structure, it should be "struct mpt2sas_port_facts" instead of Mpi2PortFactsReply.

Introduce a global ratelimit for CAPI message dumps to protect against possible log flood. Drop the ratelimit for ignored messages which is now covered by the global one.

* dl2k: Clean up rio_ioctlJeff Mahoney2012-05-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | CVE-2012-2313 The dl2k driver's rio_ioctl call has a few issues: - No permissions checking - Implements SIOCGMIIREG and SIOCGMIIREG using the SIOCDEVPRIVATE numbers - Has a few ioctls that may have been used for debugging at one point but have no place in the kernel proper. This patch removes all but the MII ioctls, renumbers them to use the standard ones, and adds the proper permission check for SIOCSMIIREG. We can also get rid of the dl2k-specific struct mii_data in favor of the generic struct mii_ioctl_data. Since we have the phyid on hand, we can add the SIOCGMIIPHY ioctl too. Most of the MII code for the driver could probably be converted to use the generic MII library but I don't have a device to test the results.

* pch_gbe: Do not abort probe on bad MACDarren Hart2012-05-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | BugLink: http://bugs.launchpad.net/bugs/1002880 commit 2b53d07891630dead46d65c8f896955fd3ae0302 upstream. If the MAC is invalid or not implemented, do not abort the probe. Issue a warning and prevent bringing the interface up until a MAC is set manually (via ifconfig $IFACE hw ether $MAC). Tested on two platforms, one with a valid MAC, the other without a MAC. The real MAC is used if present, the interface fails to come up until the MAC is set on the other. They successfully get an IP over DHCP and pass a simple ping and login over ssh test. This is meant to allow the Inforce SYS940X development board: http://www.inforcecomputing.com/SYS940X_ECX.html (and others suffering from a missing MAC) to work with the mainline kernel. Without this patch, the probe will fail and the interface will not be created, preventing the user from configuring the MAC manually. This does not make any attempt to address a missing or invalid MAC for the pch_phub driver.
