commit 5620b5f7 upstream. This patch (as1443) fixes a bug found in many of the USB serial drivers: They don't set the .usb_driver field in their usb_serial_driver structure. This field is needed for assigning dynamic IDs for device matching. In addition, starting with the 2.6.37 kernel, the .usb_driver field is needed for proper autosuspend operation. Without it, attempts to open the device file will fail. Signed-off-by:

commit a9d61bc4 upstream. I found the original patch on the db0fhn repeater wiki (couldn't find the email of the origial author) I guess it was never commited. I updated and added some Icom HAM-radio devices to the ftdi driver. Added extra comments to make clear what devices it are. Signed-off-by:

commit d14fc1a7 upstream. Alan's commit 335f8514 introduced .carrier_raised function in several drivers. That also means tty_port_block_til_ready can now suspend the process trying to open the serial port when Carrier Detect is low and put it into tty_port.open_wait queue. We need to wake up the process when Carrier Detect goes high and trigger TTY hangup when CD goes low. Some of the devices do not report modem status line changes, or at least we don't understand the status message, so for those we remove .carrier_raised again. Signed-off-by:

commit f790674d upstream. Functions set_fan_min() and set_fan_div() assume that the fan_div values have already been read from the register. The driver currently doesn't initialize them at load time, they are only set when function via686a_update_device() is called. This means that set_fan_min() and set_fan_div() misbehave if, for example, "sensors -s" is called before any monitoring application (e.g. "sensors") is has been run. Fix the problem by always initializing the fan_div values at device bind time. Signed-off-by:

commit cfa60917 upstream. Fix a hard-coded limit of a maximum of 16 cpu's per socket. The UV Broadcast Assist Unit code initializes by scanning the cpu topology of the system and assigning a master cpu for each socket and UV hub. That scan had an assumption of a limit of 16 cpus per socket. With Westmere we are going over that limit. The UV hub hardware will allow up to 32. If the scan finds the system has gone over that limit it returns an error and we print a warning and fall back to doing TLB shootdowns without the BAU. Signed-off-by:

commit 729a6a30 upstream. ata_pio_sectors() expects buffer for each sector to be contained in a single page; otherwise, it ends up overrunning the first page. This is achieved by setting queue DMA alignment. If sector_size is smaller than PAGE_SIZE and all buffers are sector_size aligned, buffer for each sector is always contained in a single page. This wasn't applied to ATAPI devices but IDENTIFY_PACKET is executed as ATA_PROT_PIO and thus uses ata_pio_sectors(). Newer versions of udev issue IDENTIFY_PACKET with unaligned buffer triggering the problem and causing oops. This patch fixes the problem by setting sdev->sector_size to ATA_SECT_SIZE on ATATPI devices and always setting DMA alignment to sector_size. While at it, add a warning for the unlikely but still possible scenario where sector_size is larger than PAGE_SIZE, in which case the alignment wouldn't be enough. Signed-off-by:

commit 05570297 upstream. When ASPM PM Feature is enabled on UMI link, devices that use ISOC stream of data transfer may be exposed to longer latency causing less than optimal per- formance of the device. The longer latencies are normal and are due to link wake time coming out of low power state which happens frequently to save power when the link is not active. The following code will make exception for certain features of ASPM to be by passed and keep the logic normal state only when the ISOC device is connected and active. This change will allow the device to run at optimal performance yet minimize the impact on overall power savings. Signed-off-by:

The preferred source address is currently ignored for local routes, which results in all local connections having a src address that is the same as the local dst address. Fix this by respecting the preferred source address when it is provided for local routes.

If security_filter_rule_init() doesn't return a rule, then not everything is as fine as the return code implies. This bug only occurs when the LSM (eg. SELinux) is disabled at runtime. Adding an empty LSM rule causes ima_match_rules() to always succeed, ignoring any remaining rules. default IMA TCB policy: # PROC_SUPER_MAGIC dont_measure fsmagic=0x9fa0 # SYSFS_MAGIC dont_measure fsmagic=0x62656572 # DEBUGFS_MAGIC dont_measure fsmagic=0x64626720 # TMPFS_MAGIC dont_measure fsmagic=0x01021994 # SECURITYFS_MAGIC dont_measure fsmagic=0x73636673 < LSM specific rule > dont_measure obj_type=var_log_t measure func=BPRM_CHECK measure func=FILE_MMAP mask=MAY_EXEC measure func=FILE_CHECK mask=MAY_READ uid=0 Thus without the patch, with the boot parameters 'tcb selinux=0', adding the above 'dont_measure obj_type=var_log_t' rule to the default IMA TCB measurement policy, would result in nothing being measured. The patch prevents the default TCB policy from being replaced. Signed-off-by:

Commit 3f5a2a71 zeroes out the statistics message block (SMB) and coalescing message block (CMB) when adapter ring resources are freed. This is desirable behavior, but, as a side effect, the commit leads to an oops when atl1_set_ringparam() attempts to alter the number of rx or tx elements in the ring buffer (by using ethtool -G, for example). We don't want SMB or CMB to change during this operation. Modify atl1_set_ringparam() to preserve SMB and CMB when changing ring parameters. Cc: stable@kernel.org Signed-off-by:

Before this patch, the following error would sometimes occur after a resume on pxa3xx: /path/to/mm/memory.c:144: bad pmd 8040542e. The problem was that a temporary page table mapping was being improperly restored. The PXA3xx resume code creates a temporary mapping of resume_turn_on_mmu to avoid a prefetch abort. The pxa3xx_resume_after_mmu code requires that the r1 register holding the address of this mapping not be modified, however, resume_turn_on_mmu does modify it. It is mostly correct in that r1 receives the base table address, but it may also get other bits in 13:0. This results in pxa3xx_resume_after_mmu restoring the original mapping to the wrong place, corrupting memory and leaving the temporary mapping in place.
