Linville says: ==================== Regarding the mac80211 bits, Johannes says: "This time, I have a fix from Arik for scheduled scan recovery (something that only recently went into the tree), a memory leak fix from Eytan and a small regulatory bugfix from Inbal. The EAPOL change from Felix makes rekeying more stable while lots of traffic is flowing, and there's Emmanuel's and my fixes for a race in the code handling powersaving clients." Regarding the NFC bits, Samuel says: "We only have one candidate for 3.14 fixes, and this is a NCI NULL pointer dereference introduced during the 3.14 merge window." Regarding the iwlwifi bits, Emmanuel says: "This should fix an issue raised in iwldvm when we have lots of association failures. There is a bugzilla for this bug - it hasn't been validated by the user, but I hope it will do the trick." Beyond that... Amitkumar Karwar brings two mwifiex fixes, one to avoid a NULL pointer dereference and another to address an improperly timed interrupt. Arend van Spriel gives us a brcmfmac fix to avoid a crash during scatter-gather packet transfers. Avinash Patila offers an mwifiex to avoid an invalid memory access when a device is removed. Bing Zhao delivers a simple fix to avoid a naming conflict between libertas and mwifiex. Felix Fietkau provides a trio of ath9k fixes that properly account for sequence numbering in ps-poll frames, reduce the rate for false positives during baseband hang detection, and fix a regression related to rx descriptor handling. James Cameron shows us a libertas fix to ignore zero-length IEs when processing scan results. Kirill Tkhai brings a hostap fix to avoid prematurely freeing a timer. Stanislaw Gruszka fixes an ath9k locking problem. Sujith Manoharan addresses ETSI compliance for a device handled by ath9k by adjusting the minimum CCA power threshold values. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2014-02-26bonding: fix a div error caused by the slave release pathNikolay Aleksandrov1-3/+1
There's a bug in the slave release function which leads the transmit functions which use the bond->slave_cnt to a div by 0 because we might just have released our last slave and made slave_cnt == 0 but at the same time we may have a transmitter after the check for an empty list which will fetch it and use it in the slave id calculation. Fix it by moving the slave_cnt after synchronize_rcu so if this was our last slave any new transmitters will see an empty slave list which is checked after rcu lock but before calling the mode transmit functions which rely on bond->slave_cnt.

2014-02-26bonding: Fix RTNL: assertion failed at net/core/rtnetlink.c for ab arp monitordingtianhong3-46/+55
Veaceslav has reported and fix this problem by commit f2ebd477f141bc0 (bonding: restructure locking of bond_ab_arp_probe()). According Jay's opinion, the current solution is not very well, because the notification is to indicate that the interface has actually changed state in a meaningful way, but these calls in the ab ARP monitor are internal settings of the flags to allow the ARP monitor to search for a slave to become active when there are no active slaves. The flag setting to active or backup is to permit the ARP monitor's response logic to do the right thing when deciding if the test slave (current_arp_slave) is up or not. So the best way to fix the problem is that we should not send a notification when the slave is in testing state, and check the state at the end of the monitor, if the slave's state recover, avoid to send pointless notification twice. And RTNL is really a big lock, hold it regardless the slave's state changed or not when the current_active_slave is null will loss performance (every 100ms), so we should hold it only when the slave's state changed and need to notify. I revert the old commit and add new modifications.

2014-02-26bonding: Fix RTNL: assertion failed at net/core/rtnetlink.c for 802.3ad modedingtianhong3-22/+75
The problem was introduced by the commit 1d3ee88ae0d (bonding: add netlink attributes to slave link dev). The bond_set_active_slave() and bond_set_backup_slave() will use rtmsg_ifinfo to send slave's states, so these two functions should be called in RTNL. In 802.3ad mode, acquiring RTNL for the __enable_port and __disable_port cases is difficult, as those calls generally already hold the state machine lock, and cannot unconditionally call rtnl_lock because either they already hold RTNL (for calls via bond_3ad_unbind_slave) or due to the potential for deadlock with bond_3ad_adapter_speed_changed, bond_3ad_adapter_duplex_changed, bond_3ad_link_change, or bond_3ad_update_lacp_rate. All four of those are called with RTNL held, and acquire the state machine lock second. The calling contexts for __enable_port and __disable_port already hold the state machine lock, and may or may not need RTNL. According to the Jay's opinion, I don't think it is a problem that the slave don't send notify message synchronously when the status changed, normally the state machine is running every 100 ms, send the notify message at the end of the state machine if the slave's state changed should be better. I fix the problem through these steps: 1). add a new function bond_set_slave_state() which could change the slave's state and call rtmsg_ifinfo() according to the input parameters called notify. 2). Add a new slave parameter which called should_notify, if the slave's state changed and don't notify yet, the parameter will be set to 1, and then if the slave's state changed again, the param will be set to 0, it indicate that the slave's state has been restored, no need to notify any one. 3). the __enable_port and __disable_port should not call rtmsg_ifinfo in the state machine lock, any change in the state of slave could set a flag in the slave, it will indicated that an rtmsg_ifinfo should be called at the end of the state machine.

Without a shutdown handler, T4 cards behave very badly after a kexec. Some firmware calls return errors indicating allocation failures, for example. This is probably because thouse resources were not released by a BYE message to the firmware, for example. Using the remove handler guarantees we will use a well tested path.

2014-02-20hostap: Do not free priv until timer handler has actually stopped using itKirill Tkhai1-1/+1
Function del_timer() does not guarantee that timer was really deleted. If the timer handler is beeing executed at the moment, the function does nothing. So, it's possible to use already freed memory in the handler: [ref: Documentation/DocBook/kernel-locking.tmpl] This was found using grep and compile-tested only.

2014-02-20net: fec: fix potential issue to avoid fec interrupt lost and crc errorDuan Fugang-B386111-6/+7
The current flow: Set TX BD ready, and then set "INT" and "PINS" bit to enable tx interrupt generation and crc checksum. There has potential issue like as: CPU fec uDMA Set tx ready bit uDMA start the BD transmission Set "INT" bit Set "PINS" bit ... Above situation cause fec tx interrupt lost and fec MAC don't do CRC checksum. The patch fix the potential issue.

2014-02-20iwlwifi: dvm: clear IWL_STA_UCODE_INPROGRESS when assoc failsEmmanuel Grumbach1-0/+1
We set IWL_STA_UCODE_INPROGRESS flag when we add a station and clear it when we send the LQ command for it. But the LQ command is sent only when the association succeeds. If the association doesn't succeed, we would leave this flag set and that wouldn't indicate the station entry as vacant.

2014-02-20tun: remove bogus hardware vlan acceleration flags from vlan_featuresFernando Luis Vazquez Cao1-1/+3
Even though only the outer vlan tag can be HW accelerated in the transmission path, in the TUN/TAP driver vlan_features mirrors hw_features, which happens to have the NETIF_F_HW_VLAN_?TAG_TX flags set. Because of this, during packet tranmisssion through a stacked vlan device dev_hard_start_xmit, (incorrectly) assuming that the vlan device supports hardware vlan acceleration, does not add the vlan header to the skb payload and the inner vlan tags are lost (vlan_tci contains the outer vlan tag when userspace reads the packet from the tap device).

2014-02-20veth: Fix vlan_features so as to be able to use stacked vlan interfacesToshiaki Makita1-1/+2
Even if we create a stacked vlan interface such as veth0.10.20, it sends single tagged frames (tagged with only vid 10). Because vlan_features of a veth interface has the NETIF_F_HW_VLAN_[CTAG/STAG]_TX bits, veth0.10 also has that feature, so dev_hard_start_xmit(veth0.10) doesn't call __vlan_put_tag() and vlan_dev_hard_start_xmit(veth0.10) overwrites vlan_tci. This prevents us from using a combination of 802.1ad and 802.1Q in containers, etc. Signed-off-by: Toshiaki Makita <makita.toshiaki@lab.ntt.co.jp> Acked-by: Flavio Leitner <fbl@redhat.com> Signed-off-by: David S.

2014-02-19xen-netfront: reset skb network header before checksumWei Liu1-0/+1
In ed1f50c3a ("net: add skb_checksum_setup") we introduced some checksum functions in core driver. Subsequent change b5cf66cd1 ("xen-netfront: use new skb_checksum_setup function") made use of those functions to replace its own implementation. However with that change netfront is broken. It sees a lot of checksum error. That's because its own implementation of checksum function was a bit hacky (dereferencing skb->data directly) while the new function was implemented using ip_hdr(). The network header is not reset before skb is passed to the new function. When the new function tries to do its job, it's confused and reports error. The fix is simple, we need to reset network header before passing skb to checksum function. Netback is not affected as it already does the right thing.

There is a long standing issue with the conversion from PFNs to addresses where people assume that shifting an unsigned long left by PAGE_SHIFT results in a correct address. This is not the case with C: the integer promotion happens at assignment after evaluation.

2014-02-18of_mdio: fix phy interrupt passingBen Dooks1-7/+9
The of_mdiobus_register_phy() is not setting phy->irq thus causing some drivers to incorrectly assume that the PHY does not have an IRQ associated with it. Not only do some drivers report no IRQ they do not install an interrupt handler for the PHY. Simplify the code setting irq and set the phy->irq at the same time so that we cover the following issues, which should cover all the cases the code will find: - Set phy->irq if node has irq property and mdio->irq is NULL - Set phy->irq if node has no irq and mdio->irq is not NULL - Leave phy->irq as PHY_POLL default if none of the above This fixes the issue: net eth0: attached PHY 1 (IRQ -1) to driver Micrel KSZ8041RNLI to the correct: net eth0: attached PHY 1 (IRQ 416) to driver Micrel KSZ8041RNLI Signed-off-by: Ben Dooks <ben.dooks@codethink.co.uk> Signed-off-by: David S.

2014-02-18net: ethernet: update dependency and help text of mvnetaThomas Petazzoni1-3/+3
With the introduction of the support for Armada 375 and Armada 38x, the hidden Kconfig option MACH_ARMADA_370_XP is being renamed to MACH_MVEBU_V7. Therefore, the dependency that was used for the mvneta driver can no longer work. This commit replaces this dependency by a dependency on PLAT_ORION, which is used similarly for the mv643xx_eth driver. In addition to this, it takes this opportunity to adjust the description and help text to indicate that the driver can is also used for Armada 38x. Note that Armada 375 cannot use this driver as it has a completely different networking unit, which will require a separate driver.
