2012-11-15tcp: fix retransmission in repair modeAndrew Vagin
Currently if a socket was repaired with a few packet in a write queue, a kernel bug may be triggered: kernel BUG at net/ipv4/tcp_output.c:2330! RIP: 0010:[<ffffffff8155784f>] tcp_retransmit_skb+0x5ff/0x610 According to the initial realization v3.4-rc2-963-gc0e88ff, all skb-s should look like already posted. This patch fixes code according with this sentence. Here are three points, which were not done in the initial patch: 1. A tcp send head should not be changed 2. Initialize TSO state of a skb 3. Reset the retransmission time This patch moves logic from tcp_sendmsg to tcp_write_xmit. A packet passes the ussual way, but isn't sent to network. This patch solves all described problems and handles tcp_sendpages. Cc: Pavel Emelyanov <xemul@parallels.com> Cc: "David S.

2012-11-15s390/3215: fix tty close handlingHeiko Carstens
The 3215 console always has the RAW3215_FIXED flag set, which causes raw3215_shutdown() not to wait for outstanding I/O requests if an attached tty gets closed. The flag however can be simply removed, so we can guarantee that all requests belonging to the tty have been processed when the tty is closed. However the tasklet that belongs to the 3215 device may be scheduled even if there is no tty attached anymore, since we have a race between console and tty processing. Thefore unconditional tty_wakekup() in raw3215_wakeup() can cause the following NULL pointer dereference: 3.465368 Unable to handle kernel pointer dereference at virtual kernel address (null) 3.465448 Oops: 0004 #1 SMP 3.465454 Modules linked in: 3.465459 CPU: 1 Not tainted 3.6.0 #1 3.465462 Process swapper/1 (pid: 0, task: 000000003ffa4428, ksp: 000000003ffb7ce0) 3.465466 Krnl PSW : 0404100180000000 0000000000162f86 (__wake_up+0x46/0xb8) 3.465480 R:0 T:1 IO:0 EX:0 Key:0 M:1 W:0 P:0 AS:0 CC:1 PM:0 EA:3 Krnl GPRS: fffffffffffffffe 0000000000000000 0000000000000160 0000000000000001 3.465492 0000000000000001 0000000000000004 0000000000000004 000000000096b490 3.465499 0000000000000001 0000000000000100 0000000000000001 0000000000000001 3.465506 070000003fc87d60 0000000000000160 000000003fc87d68 000000003fc87d00 3.465526 Krnl Code: 0000000000162f76: e3c0f0a80004 lg %r12,168(%r15) 0000000000162f7c: 58000370 l %r0,880 #0000000000162f80: c007ffffffff00 xilf %r0,4294967295 >0000000000162f86: ba102000 cs %r1,%r0,0(%r2) 0000000000162f8a: 1211 ltr %r1,%r1 0000000000162f8c: a774002f brc 7,162fea 0000000000162f90: b904002d lgr %r2,%r13 0000000000162f94: b904003a lgr %r3,%r10 3.465597 Call Trace: 3.465599 (<0400000000000000> 0x400000000000000) 3.465602 <000000000048c77e> raw3215_wakeup+0x2e/0x40 3.465607 <0000000000134d66> tasklet_action+0x96/0x168 3.465612 <000000000013423c> __do_softirq+0xd8/0x21c 3.465615 <0000000000134678> irq_exit+0xa8/0xac 3.465617 <000000000046c232> do_IRQ+0x182/0x248 3.465621 <00000000005c8296> io_return+0x0/0x8 3.465625 <00000000005c7cac> vtime_stop_cpu+0x4c/0xb8 3.465629 (<0000000000194e06> tick_nohz_idle_enter+0x4e/0x74) 3.465633 <0000000000104760> cpu_idle+0x170/0x184 3.465636 <00000000005b5182> smp_start_secondary+0xd6/0xe0 3.465641 <00000000005c86be> restart_int_handler+0x56/0x6c 3.465643 <0000000000000000> 0x0 3.465645 Last Breaking-Event-Address: 3.465647 <0000000000403136> tty_wakeup+0x46/0x98 3.465652 3.465654 Kernel panic - not syncing: Fatal exception in interrupt 01: HCPGIR450W CP entered; disabled wait PSW 00020001 80000000 00000000 0010F63C The easiest solution is simply to check if tty is NULL in the tasklet.

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.

This avoids a cascade of oopses caused when the initial pstore_console_write passes a null which in turn causes writes to the console causing further oopses in subsequent pstore_console_write calls.

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.

2012-11-14ALSA: 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().

When regulator_register fails and exits through the scrub path the regulator_put function was called whilst holding the regulator_list_mutex, causing deadlock. This patch adds a private version of the regulator_put function which can be safely called whilst holding the mutex, replacing the aforementioned call.

2012-11-13vxlan: Update hard_header_len based on lowerdev when instantiating VXLANAlexander Duyck
In the event of a VXLAN device being linked to a device that has a hard_header_len greater than that of standard ethernet we could end up with the hard_header_len not being large enough for outgoing frames. In order to prevent this we should update the length when a lowerdev is provided.

2012-11-13MAINTAINERS: i2c: 7 years, this is itJean Delvare
I have been maintaining the i2c subsystem for 7 years now, it's about time to let someone else take over. Just before I leave, I would like to thank several individuals who made this possible at all: * Greg Kroah-Hartman, for his faith in my potential subsystem maintainer skills. Greg, I hope I met your expectations. * Late David Brownell, for helping me convert the i2c subsystem to the standard device driver model. 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. I hope I did not forget anyone, please forgive me if I did. Another big thank is due to Wolfram again, who quickly proposed to take over as the main i2c subsystem maintainer. This will allow for a smooth and fast transition. Note that I will keep maintaining all I2C/SMBus controller drivers for PC systems as well as a few others. I am hereby updating MAINTAINERS accordingly. I'll also keep maintaining user-space i2c-tools.

Commit 6bd4a5d96c08dc2380f8053b1bd4f879f55cd3c9 changed the ANDROID_ALARM_GET_TIME ioctls from IOW to IOR. While technically correct, the _IOC_DIR bits are ignored by alarm_ioctl, so the commit breaks a userspace ABI used by all existing Android devices for a purely cosmetic reason. Revert it.

2012-11-13vxlan: Fix error that was resulting in VXLAN MTU size being 10 bytes too largeAlexander Duyck
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.

2012-11-13tcp: tcp_replace_ts_recent() should not be called from tcp_validate_incoming()Eric Dumazet
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.
