2014-01-07extcon: gpio: Request gpio pin before modifying its stateGuenter Roeck
Commit 338de0ca (extcon: gpio: Use gpio driver/chip debounce if supported) introduced a call to gpio_set_debounce() before actually requesting the respective gpio pin from the gpio subsystem. The gpio subsystem expects that a gpio pin was requested before modifying its state. Not doing so results in a warning from gpiolib, and the gpio pin is auto-requested. This in turn causes the subsequent devm_gpio_request_one() to fail. So devm_gpio_request_one() must be called prior to calling gpio_set_debounce().

2014-01-06agp: Support 64-bit APBASEBjorn Helgaas
Per the AGP 3.0 spec, APBASE is a standard PCI BAR and may be either 32 bits or 64 bits wide. Many drivers read APBASE directly, but they only handled 32-bit BARs. The PCI core reads APBASE at enumeration-time. Use pci_bus_address() instead of reading it again in the driver. This works correctly for both 32-bit and 64-bit BARs.

2014-01-06Bluetooth: Always wait for a connection on RFCOMM open()Gianluca Anzolin
This patch fixes two regressions introduced with the recent rfcomm tty rework. The current code uses the carrier_raised() method to wait for the bluetooth connection when a process opens the tty. However processes may open the port with the O_NONBLOCK flag or set the CLOCAL termios flag: in these cases the open() syscall returns immediately without waiting for the bluetooth connection to complete. This behaviour confuses userspace which expects an established bluetooth connection. The patch restores the old behaviour by waiting for the connection in rfcomm_dev_activate() and removes carrier_raised() from the tty_port ops. As a side effect the new code also fixes the case in which the rfcomm tty device is created with the flag RFCOMM_REUSE_DLC: the old code didn't call device_move() and ModemManager skipped the detection probe. Now device_move() is always called inside rfcomm_dev_activate().

2014-01-06Bluetooth: Release RFCOMM port when the last user closes the TTYGianluca Anzolin
This patch fixes a userspace regression introduced by the commit 29cd718b. If the rfcomm device was created with the flag RFCOMM_RELEASE_ONHUP the user space expects that the tty_port is released as soon as the last process closes the tty. The current code attempts to release the port in the function rfcomm_dev_state_change(). However it won't get a reference to the relevant tty to send a HUP: at that point the tty is already destroyed and therefore NULL. This patch fixes the regression by taking over the tty refcount in the tty install method(). This way the tty_port is automatically released as soon as the tty is destroyed. As a consequence the check for RFCOMM_RELEASE_ONHUP flag in the hangup() method is now redundant. Instead we have to be careful with the reference counting in the rfcomm_release_dev() function.

2014-01-06bridge: use spin_lock_bh() in br_multicast_set_hash_maxCurt Brune
br_multicast_set_hash_max() is called from process context in net/bridge/br_sysfs_br.c by the sysfs store_hash_max() function. br_multicast_set_hash_max() calls spin_lock(&br->multicast_lock), which can deadlock the CPU if a softirq that also tries to take the same lock interrupts br_multicast_set_hash_max() while the lock is held . This can happen quite easily when any of the bridge multicast timers expire, which try to take the same lock. The fix here is to use spin_lock_bh(), preventing other softirqs from executing on this CPU. Steps to reproduce: 1. Create a bridge with several interfaces (I used 4). 2. Set the "multicast query interval" to a low number, like 2. 3. Enable the bridge as a multicast querier. 4. Repeatedly set the bridge hash_max parameter via sysfs. # brctl addbr br0 # brctl addif br0 eth1 eth2 eth3 eth4 # brctl setmcqi br0 2 # brctl setmcquerier br0 1 # while true ; do echo 4096 > /sys/class/net/br0/bridge/hash_max; done Signed-off-by: Curt Brune <curt@cumulusnetworks.com> Signed-off-by: Scott Feldman <sfeldma@cumulusnetworks.com> Signed-off-by: David S.

2014-01-06vxlan: keep original skb ownershipEric Dumazet
Sathya Perla posted a patch trying to address following problem : <quote> The vxlan driver sets itself as the socket owner for all the TX flows it encapsulates (using vxlan_set_owner()) and assigns it's own skb destructor. This causes all tunneled traffic to land up on only one TXQ as all encapsulated skbs refer to the vxlan socket and not the original socket. Also, the vxlan skb destructor breaks some functionality for tunneled traffic like wmem accounting and as TCP small queues and FQ/pacing packet scheduler. </quote> I reworked Sathya patch and added some explanations. vxlan_xmit() can avoid one skb_clone()/dev_kfree_skb() pair and gain better drop monitor accuracy, by calling kfree_skb() when appropriate. The UDP socket used by vxlan to perform encapsulation of xmit packets do not need to be alive while packets leave vxlan code. Its better to keep original socket ownership to get proper feedback from qdisc and NIC layers. We use skb->sk to A) control amount of bytes/packets queued on behalf of a socket, but prior vxlan code did the skb->sk transfert without any limit/control on vxlan socket sk_sndbuf. B) security purposes (as selinux) or netfilter uses, and I do not think anything is prepared to handle vxlan stacked case in this area. By not changing ownership, vxlan tunnels behave like other tunnels. As Stephen mentioned, we might do the same change in L2TP.

2014-01-06hso: fix handling of modem port SERIAL_STATE notificationsDan Williams
The existing serial state notification handling expected older Option devices, having a hardcoded assumption that the Modem port was always USB interface #2. That isn't true for devices from the past few years. hso_serial_state_notification is a local cache of a USB Communications Interface Class SERIAL_STATE notification from the device, and the USB CDC specification (section 6.3, table 67 "Class-Specific Notifications") defines wIndex as the USB interface the event applies to. For hso devices this will always be the Modem port, as the Modem port is the only port which is set up to receive them by the driver. So instead of always expecting USB interface #2, instead validate the notification with the actual USB interface number of the Modem port. Signed-off-by: Dan Williams <dcbw@redhat.com> Tested-by: H.
