2011-03-02xhci: Fix an error in count_sg_trbs_needed()Paul Zimmerman
commit bcd2fde05341cef0052e49566ec88b406a521cf3 upstream. The expression while (running_total < sg_dma_len(sg)) does not take into account that the remaining data length can be less than sg_dma_len(sg). In that case, running_total can end up being greater than the total data length, so an extra TRB is counted. Changing the expression to while (running_total < sg_dma_len(sg) && running_total < temp) fixes that. This patch should be queued for stable kernels back to 2.6.31.

2011-03-02xhci: Fix errors in the running total calculations in the TRB mathPaul Zimmerman
commit 5807795bd4dececdf553719cc02869e633395787 upstream. Calculations like running_total = TRB_MAX_BUFF_SIZE - (sg_dma_address(sg) & (TRB_MAX_BUFF_SIZE - 1)); if (running_total != 0) num_trbs++; are incorrect, because running_total can never be zero, so the if() expression will never be true. I think the intention was that running_total be in the range of 0 to TRB_MAX_BUFF_SIZE-1, not 1 to TRB_MAX_BUFF_SIZE. So adding a running_total &= TRB_MAX_BUFF_SIZE - 1; fixes the problem.

2011-03-02xhci: Clarify some expressions in the TRB mathPaul Zimmerman
commit a2490187011cc2263117626615a581927d19f1d3 upstream. This makes it easier to spot some problems, which will be fixed by the next patch in the series. Also change dev_dbg to dev_err in check_trb_math(), so any math errors will be visible even when running with debug disabled. Note: This patch changes the expressions containing "((1 << TRB_MAX_BUFF_SHIFT) - 1)" to use the equivalent "(TRB_MAX_BUFF_SIZE - 1)". No change in behavior is intended for those expressions.

2011-03-02md: correctly handle probe of an 'mdp' device.NeilBrown
commit 8f5f02c460b7ca74ce55ce126ce0c1e58a3f923d upstream. 'mdp' devices are md devices with preallocated device numbers for partitions. As such it is possible to mknod and open a partition before opening the whole device. this causes md_probe() to be called with a device number of a partition, which in-turn calls mddev_find with such a number. However mddev_find expects the number of a 'whole device' and does the wrong thing with partition numbers. So add code to mddev_find to remove the 'partition' part of a device number and just work with the 'whole device'.

commit 72a012ce0a02c6c616676a24b40ff81d1aaeafda upstream. My Galaxy Spica needs this quirk when in modem mode, otherwise it causes endless USB bus resets and is unusable in this mode. Unfortunately Samsung decided to reuse ID of its old CDMA phone SGH-I500 for the modem part. That's why in addition to this patch the visor driver must be prevented from binding to SPH-I500 ID, so ACM driver can do that.

commit acb52cb1613e1d3c8a8c650717cc51965c60d7d4 upstream. [USB]Add Samsung SGH-I500/Android modem ID switch to visor driver Samsung decided to reuse USB ID of its old CDMA phone SGH-I500 for the modem part of some of their Android phones. At least Galaxy Spica is affected. This modem needs ACM driver and does not work with visor driver which binds the conflicting ID for SGH-I500. Because SGH-I500 is pretty an old hardware its best to add switch to visor driver in cause somebody still wants to use that phone with Linux. Note that this is needed only when using the Android phone as modem, not in USB storage or ADB mode. Signed-off-by: Maciej Szmigiero <mhej@o2.pl> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2011-03-02usb: musb: omap2430: fix kernel panic on rebootJohan Hovold
commit b193b412e62b134adf69af286c7e7f8e99259350 upstream. Cancel idle timer in musb_platform_exit. The idle timer could trigger after clock had been disabled leading to kernel panic when MUSB_DEVCTL is accessed in musb_do_idle on 2.6.37. The fault below is no longer triggered on 2.6.38-rc4 (clock is disabled later, and only if compiled as a module, and the offending memory access has moved) but the timer should be cancelled nonetheless.

2011-03-02dm raid1: fix null pointer dereference in suspendTakahiro Yasui
commit 558569aa9d83e016295bac77d900342908d7fd85 upstream. When suspending a failed mirror, bios are completed by mirror_end_io() and __rh_lookup() in dm_rh_dec() returns NULL where a non-NULL return value is required by design. Fix this by not changing the state of the recovery failed region from DM_RH_RECOVERING to DM_RH_NOSYNC in dm_rh_recovery_end(). Issue On 2.6.33-rc1 kernel, I hit the bug when I suspended the failed mirror by dmsetup command.

When recovery_complete() is executed between dm_rh_update_states() and dm_writes() in do_mirror(), bios are processed with the region state, DM_RH_NOSYNC. However, the region data is freed without checking its pending count when dm_rh_update_states() is called next time. When bios are finished by mirror_end_io(), __rh_lookup() in dm_rh_dec() returns NULL even though a valid return value are expected. Solution Remove the state change of the recovery failed region from DM_RH_RECOVERING to DM_RH_NOSYNC in dm_rh_recovery_end(). We can remove the state change because: - If the region data has been released by dm_rh_update_states(), a new region data is created with the state of DM_RH_NOSYNC, and bios are processed according to the DM_RH_NOSYNC state. - If the region data has not been released by dm_rh_update_states(), a state of the region is DM_RH_RECOVERING and bios are put in the delayed_bio list. The flag change from DM_RH_RECOVERING to DM_RH_NOSYNC in dm_rh_recovery_end() was added in the following commit: dm raid1: handle resync failures author Jonathan Brassow <jbrassow@redhat.com> Thu, 12 Jul 2007 16:29:04 +0000 (17:29 +0100) http://git.kernel.org/linus/f44db678edcc6f4c2779ac43f63f0b9dfa28b724 Signed-off-by: Takahiro Yasui <tyasui@redhat.com> Reviewed-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com> Cc: maximilian attems <max@stro.at> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-03-02dm raid1: fail writes if errors are not handled and log failsMikulas Patocka
commit 5528d17de1cf1462f285c40ccaf8e0d0e4c64dc0 upstream. If the mirror log fails when the handle_errors option was not selected and there is no remaining valid mirror leg, writes return success even though they weren't actually written to any device. This patch completes them with EIO instead. This code path is taken: do_writes: bio_list_merge(&ms->failures, &sync); do_failures: if (!get_valid_mirror(ms)) (false) else if (errors_handled(ms)) (false) else bio_endio(bio, 0); The logic in do_failures is based on presuming that the write was already tried: if it succeeded at least on one leg (without handle_errors) it is reported as success.

2011-03-02ixgbe: prevent speculative processing of descriptors before readyMilton Miller
commit 3c945e5b3719bcc18c6ddd31bbcae8ef94f3d19a upstream. The PowerPC architecture does not require loads to independent bytes to be ordered without adding an explicit barrier. In ixgbe_clean_rx_irq we load the status bit then load the packet data. With packet split disabled if these loads go out of order we get a stale packet, but we will notice the bad sequence numbers and drop it. The problem occurs with packet split enabled where the TCP/IP header and data are in different descriptors. If the reads go out of order we may have data that doesn't match the TCP/IP header. Since we use hardware checksumming this bad data is never verified and it makes it all the way to the application. This bug was found during stress testing and adding this barrier has been shown to fix it.

This is related to commit f88a4a9b65a6f3422b81be995535d0e69df11bb8 upstream, but the bug cannot be properly fixed without the other changes to VLAN tagging in 2.6.37. bond_na_send() attempts to insert a VLAN tag in between building and sending packets of the respective formats. If the slave does not implement hardware VLAN tag insertion then vlan_put_tag() will mangle the network-layer header because the Ethernet header is not present at this point (unlike in bond_arp_send()).

2011-03-02OHCI: work around for nVidia shutdown problemAlan Stern
commit 3df7169e73fc1d71a39cffeacc969f6840cdf52b upstream. This patch (as1417) fixes a problem affecting some (or all) nVidia chipsets. When the computer is shut down, the OHCI controllers continue to power the USB buses and evidently they drive a Reset signal out all their ports. This prevents attached devices from going to low power. Mouse LEDs stay on, for example, which is disconcerting for users and a drain on laptop batteries. The fix involves leaving each OHCI controller in the OPERATIONAL state during system shutdown rather than putting it in the RESET state. Although this nominally means the controller is running, in fact it's not doing very much since all the schedules are all disabled. However there is ongoing DMA to the Host Controller Communications Area, so the patch also disables the bus-master capability of all PCI USB controllers after the shutdown routine runs. The fix is applied only to nVidia-based PCI OHCI controllers, so it shouldn't cause problems on systems using other hardware. As an added safety measure, in case the kernel encounters one of these running controllers during boot, the patch changes quirk_usb_handoff_ohci() (which runs early on during PCI discovery) to reset the controller before anything bad can happen.

2011-03-02Fix pktcdvd ioctl dev_minor range checkDan Rosenberg
commit 252a52aa4fa22a668f019e55b3aac3ff71ec1c29 upstream. The PKT_CTRL_CMD_STATUS device ioctl retrieves a pointer to a pktcdvd_device from the global pkt_devs array. The index into this array is provided directly by the user and is a signed integer, so the comparison to ensure that it falls within the bounds of this array will fail when provided with a negative index. This can be used to read arbitrary kernel memory or cause a crash due to an invalid pointer dereference. This can be exploited by users with permission to open /dev/pktcdvd/control (on many distributions, this is readable by group "cdrom").

commit bcfe42e98047f1935c5571c8ea77beb2d43ec19d upstream. There's a branch at the end of this function that is supposed to normalize the return value with what the mid-layer expects. In this one case, we get it wrong. Also increase the verbosity of the INFO level printk at the end of mptscsih_abort to include the actual return value and the scmd->serial_number. The reason being success or failure is actually determined by the state of the internal tag list when a TMF is issued, and not the return value of the TMF cmd. The serial_number is also used in this decision, thus it's useful to know for debugging purposes. Reported-by: Peter M.

2011-02-17usb: Realloc xHCI structures after a hub is verified.Sarah Sharp
commit 653a39d1f61bdc9f277766736d21d2e9be0391cb upstream. When there's an xHCI host power loss after a suspend from memory, the USB core attempts to reset and verify the USB devices that are attached to the system. The xHCI driver has to reallocate those devices, since the hardware lost all knowledge of them during the power loss. When a hub is plugged in, and the host loses power, the xHCI hardware structures are not updated to say the device is a hub. This is usually done in hub_configure() when the USB hub is detected. That function is skipped during a reset and verify by the USB core, since the core restores the old configuration and alternate settings, and the hub driver has no idea this happened. This bug makes the xHCI host controller reject the enumeration of low speed devices under the resumed hub. Therefore, make the USB core re-setup the internal xHCI hub device information by calling update_hub_device() when hub_activate() is called for a hub reset resume. After a host power loss, all devices under the roothub get a reset-resume or a disconnect. This patch should be queued for the 2.6.37 stable tree.

This additional locking is unnecessary because i_size_write() is already protected by the existing critical section in dm_swap_table(). DM already has a reference on md->bdev so the associated bd_inode may be changed without lifetime concerns. A negative side-effect of having held md->bdev->bd_inode->i_mutex was that a concurrent DM device resize and flush (via fsync) would deadlock. Dropping md->bdev->bd_inode->i_mutex eliminates this potential for deadlock. The following reproducer no longer deadlocks: https://www.redhat.com/archives/dm-devel/2009-July/msg00284.html Signed-off-by: Mike Snitzer <snitzer@redhat.com> Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-02-17tpm_tis: Use timeouts returned from TPMStefan Berger
commit 9b29050f8f75916f974a2d231ae5d3cd59792296 upstream. The current TPM TIS driver in git discards the timeout values returned from the TPM. The check of the response packet needs to consider that the return_code field is 0 on success and the size of the expected packet is equivalent to the header size + u32 length indicator for the TPM_GetCapability() result + 3 timeout indicators of type u32. I am also adding a sysfs entry 'timeouts' showing the timeouts that are being used.

2011-02-17TPM: Long default timeout fixRajiv Andrade
commit c4ff4b829ef9e6353c0b133b7adb564a68054979 upstream. If duration variable value is 0 at this point, it's because chip->vendor.duration wasn't filled by tpm_get_timeouts() yet. This patch sets then the lowest timeout just to give enough time for tpm_get_timeouts() to further succeed. This fix avoids long boot times in case another entity attempts to send commands to the TPM when the TPM isn't accessible.

commit 77c5fd19075d299fe820bb59bb21b0b113676e20 upstream. pata_mpc52xx supports BMDMA but inherits ata_sff_port_ops which triggers BUG_ON() when a DMA command is issued. Fix it.

2011-02-17md: fix regression with re-adding devices to arrays with no metadataNeilBrown
commit bf572541ab44240163eaa2d486b06f306a31d45a upstream. Commit 1a855a0606 (2.6.37-rc4) fixed a problem where devices were re-added when they shouldn't be but caused a regression in a less common case that means sometimes devices cannot be re-added when they should be. In particular, when re-adding a device to an array without metadata we should always access the device, but after the above commit we didn't. This patch sets the In_sync flag in that case so that the re-add succeeds. This patch is suitable for any -stable kernel to which 1a855a0606 was applied.

2011-02-17hostap_cs: fix sleeping function called from invalid contextStanislaw Gruszka
commit 4e5518ca53be29c1ec3c00089c97bef36bfed515 upstream. pcmcia_request_irq() and pcmcia_enable_device() are intended to be called from process context (first function allocate memory with GFP_KERNEL, second take a mutex). We can not take spin lock and call them. It's safe to move spin lock after pcmcia_enable_device() as we still hold off IRQ until dev->base_addr is 0 and driver will not proceed with interrupts when is not ready.

2011-02-17drivers: update to pl2303 usb-serial to support Motorola cablesDario Lombardo
commit 96a3e79edff6f41b0f115a82f1a39d66218077a7 upstream. Added 0x0307 device id to support Motorola cables to the pl2303 usb serial driver. This cable has a modified chip that is a pl2303, but declares itself as 0307. Fixed by adding the right device id to the supported devices list, assigning it the code labeled PL2303_PRODUCT_ID_MOTOROLA.

2011-02-17USB: serial: pl2303: Hybrid reader Uniform HCR331Simone Contini
commit 18344a1cd5889d48dac67229fcf024ed300030d5 upstream. I tried a magnetic stripe reader (http://www.kimaldi.com/kimaldi_eng/productos/lectores_de_tarjetas/lectores_tarjeta_chip_y_dni/lector_hibrido_uniform_hcr_331) and I see that it is interfaced with a PL2303. I wrote a patch to use your driver which simply adds the product ID for the device and it seems working fine.
