2012-11-15mtd: nand: fix Samsung SLC NAND identification regressionBrian Norris
A combination of the following two commits caused a regression in 3.7-rc1 when identifying some Samsung NAND, so that some previously working NAND were no longer detected properly: commit e3b88bd604283ef83ae6e8f53622d5b1ffe9d43a mtd: nand: add generic READ ID length calculation functions commit e2d3a35ee427aaba99b6c68a56609ce276c51270 mtd: nand: detect Samsung K9GBG08U0A, K9GAG08U0F ID Particularly, a regression was seen on Samsung K9F2G08U0B, with the following full 8-byte READ ID string: ec da 10 95 44 00 ec da The basic problem is that Samsung manufactures both SLC and MLC NAND that use a non-standard decoding table for deriving information from their IDs. I have heuristically determined that all the chips that use the new table have ID strings which wrap around after the 6th byte. Unfortunately, I overlooked the fact that some older Samsung SLC (which use a different decoding table) have "5 byte ID strings" which also wrap around after the 6th byte. This patch re-introduces a distinction between these old and new Samsung NAND by checking that the 6th byte is non-zero, allowing both old and new Samsung NAND to be detected properly.

2012-11-14Revert "drivers/net/phy/mdio-bitbang.c: Call mdiobus_unregister before ↵David S. Miller
mdiobus_free" This reverts commit aa731872f7d33dcb8b54dad0cfb82d4e4d195d7e. As pointed out by Ben Hutchings, this change is not correct. mdiobus_unregister() can't be called if the bus isn't registered yet, however this change can result in situations which cause that to happen. Part of the confusion here revolves around the fact that the callers of this module control registration/unregistration, rather than the module itself. Signed-off-by: David S.

2012-11-14net/smsc911x: Fix ready check in cases where WORD_SWAP is neededKamlakant Patel
The chip ready check added by the commit 3ac3546e [Always wait for the chip to be ready] does not work when the register read/write is word swapped. This check has been added before the WORD_SWAP register is programmed, so we need to check for swapped register value as well. Bit 16 is marked as RESERVED in SMSC datasheet, Steve Glendinning <steve@shawell.net> checked with SMSC and wrote: The chip architects have concluded we should be reading PMT_CTRL until we see any of bits 0, 8, 16 or 24 set. Then we should read BYTE_TEST to check the byte order is correct (as we already do). The rationale behind this is that some of the chip variants have word order swapping features too, so the READY bit could actually be in any of the 4 possible locations. The architects have confirmed that if any of these 4 positions is set the chip is ready. The other 3 locations will either never be set or can only go high after READY does (so also indicate the device is ready). This change will check for the READY bit at the 16th position. We do not check the other two cases (bit 8 and 24) since the driver does not support byte-swapped register read/write.

2012-11-14drivers/net: fix tasklet misuse issueXiaotian Feng
In commit 175c0dff, drivers uses tasklet_kill to avoid put disabled tasklet on the tasklet vec. But some of the drivers uses tasklet_init & tasklet_disable in the driver init code, then tasklet_enable when it is opened. This makes tasklet_enable on a killed tasklet and make ksoftirqd crazy then. Normally, drivers should use tasklet_init/tasklet_kill on device open/remove, and use tasklet_disable/tasklet_enable on device suspend/resume.

2012-11-14ipv4/ip_vti.c: VTI fix post-decryption forwardingSaurabh Mohan
With the latest kernel there are two things that must be done post decryption so that the packet are forwarded. 1. Remove the mark from the packet. This will cause the packet to not match the ipsec-policy again. However doing this causes the post-decryption check to fail also and the packet will get dropped. (cat /proc/net/xfrm_stat). 2. Remove the sp association in the skbuff so that no policy check is done on the packet for VTI tunnels. Due to #2 above we must now do a security-policy check in the vti rcv path prior to resetting the mark in the skbuff.

2012-11-14TTY: hvc_console, fix port reference count going to zero prematurelyPaul Mackerras
Commit bdb498c20040 "TTY: hvc_console, add tty install" took the port refcounting out of hvc_open()/hvc_close(), but failed to remove the kref_put() and tty_kref_put() calls in hvc_hangup() that were there to remove the extra references that hvc_open() had taken. The result was that doing a vhangup() when the current terminal was a hvc_console, then closing the current terminal, would end up calling destroy_hvc_struct() and making the port disappear entirely. This meant that Fedora 17 systems would boot up but then not display the login prompt on the console, and attempts to open /dev/hvc0 would give a "No such device" error. This fixes it by removing the extra kref_put() and tty_kref_put() calls.

2012-11-14i2c: omap: ensure writes to dev->buf_len are orderedFelipe Balbi
if we allow compiler reorder our writes, we could fall into a situation where dev->buf_len is reset for no apparent reason. This bug was found with a simple script which would transfer data to an i2c client from 1 to 1024 bytes (a simple for loop), when we got to transfer sizes bigger than the fifo size, dev->buf_len was reset to zero before we had an oportunity to handle XDR Interrupt. Because dev->buf_len was zero, we entered omap_i2c_transmit_data() to transfer zero bytes, which would mean we would just silently exit omap_i2c_transmit_data() without actually writing anything to DATA register. That would cause XDR IRQ to trigger forever and we would never transfer the remaining bytes. After adding the memory barrier, we also drop resetting dev->buf_len to zero in omap_i2c_xfer_msg() because both omap_i2c_transmit_data() and omap_i2c_receive_data() will act until dev->buf_len reaches zero, rendering the other write in omap_i2c_xfer_msg() redundant. This patch has been tested with pandaboard for a few iterations of the script mentioned above. Signed-off-by: Felipe Balbi <balbi@ti.com> Signed-off-by: Wolfram Sang <w.sang@pengutronix.de>
2012-11-14ALSA: usb-audio: Fix mutex deadlock at disconnectionTakashi Iwai
The recent change for USB-audio disconnection race fixes introduced a mutex deadlock again. There is a circular dependency between chip->shutdown_rwsem and pcm->open_mutex, depicted like below, when a device is opened during the disconnection operation: A. snd_usb_audio_disconnect() -> card.c::register_mutex -> chip->shutdown_rwsem (write) -> snd_card_disconnect() -> pcm.c::register_mutex -> pcm->open_mutex B. snd_pcm_open() -> pcm->open_mutex -> snd_usb_pcm_open() -> chip->shutdown_rwsem (read) Since the chip->shutdown_rwsem protection in the case A is required only for turning on the chip->shutdown flag and it doesn't have to be taken for the whole operation, we can reduce its window in snd_usb_audio_disconnect().

2012-11-14iwlwifi: fix monitor mode FCS flagJohannes Berg
When the firmware is in SNIFFER mode, it leaves the FCS at the end of frame. Not telling mac80211 means it won't add the right flag to the radiotap header and that confuses wireshark.

2012-11-13[SCSI] sd: Implement support for WRITE SAMEMartin K. Petersen
Implement support for WRITE SAME(10) and WRITE SAME(16) in the SCSI disk driver. - We set the default maximum to 0xFFFF because there are several devices out there that only support two-byte block counts even with WRITE SAME(16). We only enable transfers bigger than 0xFFFF if the device explicitly reports MAXIMUM WRITE SAME LENGTH in the BLOCK LIMITS VPD. - max_write_same_blocks can be overriden per-device basis in sysfs. - The UNMAP discovery heuristics remain unchanged but the discard limits are tweaked to match the "real" WRITE SAME commands. - In the error handling logic we now distinguish between WRITE SAME with and without UNMAP set. The discovery process heuristics are: - If the device reports a SCSI level of SPC-3 or greater we'll issue READ SUPPORTED OPERATION CODES to find out whether WRITE SAME(16) is supported. If that's the case we will use it. - If the device supports the block limits VPD and reports a MAXIMUM WRITE SAME LENGTH bigger than 0xFFFF we will use WRITE SAME(16). - Otherwise we will use WRITE SAME(10) unless the target LBA is beyond 0xFFFFFFFF or the block count exceeds 0xFFFF. - no_write_same is set for ATA, FireWire and USB.

Rest in peace David, we're missing you. * Ben Dooks, for stepping in when I asked for someone to take care of the huge flow of new i2c adapter drivers for embedded systems. * Wolfram Sang, for joining the crew when it became clear that there was more review work than Ben and myself could deal with.

This change fixes an issue I found where VXLAN frames were fragmented when they were up to the VXLAN MTU size. I root caused the issue to the fact that the headroom was 4 + 20 + 8 + 8. This math doesn't appear to be correct because we are not inserting a VLAN header, but instead a 2nd Ethernet header. As such the math for the overhead should be 20 + 8 + 8 + 14 to account for the extra headers that are inserted for VXLAN.

We added support for RFC 5961 in latest kernels but TCP fails to perform exhaustive check of ACK sequence. We can update our view of peer tsval from a frame that is later discarded by tcp_ack() This makes timestamps enabled sessions vulnerable to injection of a high tsval : peers start an ACK storm, since the victim sends a dupack each time it receives an ACK from the other peer. As tcp_validate_incoming() is called before tcp_ack(), we should not peform tcp_replace_ts_recent() from it, and let callers do it at the right time.

2012-11-13net: cdc_ncm: add Huawei devicesBjørn Mork
A number of Huawei 3G and LTE modems implement a CDC NCM function, including the necessary functional descriptors, but using a non standard interface layout and class/subclass/protocol codes. These devices can be handled by this driver with only a minor change to the probing logic, allowing a single combined control and data interface. This works because the devices - include a CDC Union descriptor labelling the combined interface as both master and slave, and - have an alternate setting #1 for the bulk endpoints on the combined interface. The 3G/LTE network connection is managed by vendor specific AT commands on a serial function in the same composite device. Handling the managment function is out of the scope of this driver. It will be handled by an appropriate USB serial driver.

2012-11-13qeth: set new mac even if old mac is goneUrsula Braun
If the set_mac_address() function of qeth is invoked, qeth deletes the old mac address first on OSA. Only if deletion returns successfully the new mac address is set on OSA. Deletion may return with a return value "MAC not found on OSA". In this case qeth should continue setting the new mac address. When the OSA cable is pulled, OSA forgets any set mac address. If the OSA network interface acts as a slave to a bonding master interface, bonding can invoke the set_mac_address function for failover purposes and depends on successful setting of the new mac address even though the old mac address could no longer be deleted.

2012-11-13qeth: Fix IPA_CMD_QIPASSIST return code handlingStefan Raspl
Return codes of IPA_CMD_QIPASSIST are not checked, especially the ones which indicate that the command is not supported. As a result, the device driver would not enable all available features on older card generations. This patch adds proper checking and sets the bare minimum in the supported functions flags to avoid follow-on errors.

2012-11-13Revert "USB/host: Cleanup unneccessary irq disable code"Greg Kroah-Hartman
This reverts commit 73d4066055e0e2830533041f4b91df8e6e5976ff. Martin Steigerwald reported that this change caused a hard lockup when using USB if threadirqs are enabled. Thomas pointed out that this patch is incorrect, and can cause problems. So revert it to get the previously working functionality back.

Commit f79b2d0f (USB: keyspan: fix NULL-pointer dereferences and memory leaks) had a small typo which made the driver use wrong offsets when mapping serial port private data. This results in in a GPF when the port is opened.

2012-11-13MIPS: Malta: Fix interupt number of CBUS UART.Ralf Baechle
The CBUS UART's interrupt number was wrong conflicting with the interrupt being tied to the Intel PIIX4. Since the PIIX4's interrupt is registered before the CBUS UART which is not being used on most systems this would not be noticed. Attempts to open the ttyS2 CBUS UART would result in: genirq: Flags mismatch irq 18. 00000000 (serial) vs. 00010000 (XT-PIC cascade) serial_link_irq_chain: request failed: -16 for irq: 18 Qemu was written to match the kernel so will need to be fixed also.
