This patch adds a check if the dataroom of skb contains a dispatch value by checking if skb->len != 0. This patch also change the dispatch evaluation by the recently introduced helpers for checking the common 6LoWPAN dispatch values for IPv6 and IPHC header. There was also a forgotten else branch which should drop the packet if no matching dispatch is available. Signed-off-by:

The commit 89cbb063 introduced support for deferred connection parameter removal when unpairing by removing them only once an existing connection gets disconnected. However, it failed to address the scenario when we're *not* connected and do an unpair operation. What makes things worse is that most user space BlueZ versions will first issue a disconnect request and only then unpair, meaning the buggy code will be triggered every time. This effectively causes the kernel to resume scanning and reconnect to a device for which we've removed all keys and GATT database information. This patch fixes the issue by adding the missing call to the hci_conn_params_del() function to a branch which handles the case of no existing connection. Signed-off-by:

The latest Apple Bluetooth controllers with Broadcom chip in it have a small design change. Instead of including a USB hub with mouse and keyboard devices, they are now HID interfaces on the same device.

For the controllers from Intel and Broadcom (including Apple), it is helpful to have the information about the manufacturer send out early. This patch sets the hdev->manufacturer information which will be send out before actually calling the vendor specific hdev->setup driver callback. Signed-off-by:

Marcel Holtmann authored
Before the vendor specific setup stage is triggered call back into the core to trigger an internal notification event. That event is used to send an index update to the monitor interface. With that specific event it is possible to update userspace with manufacturer information before any HCI command has been executed. This is useful for early stage debugging of vendor specific initialization sequences. Signed-off-by:

The HIDP specs define an idle-timeout which automatically disconnects a device. This has always been implemented in the HIDP layer and forced a synchronous shutdown of the hidp-scheduler. This works just fine, but lacks a forced disconnect on the underlying l2cap channels. This has been broken since: commit 5205185d Author: David Herrmann <dh.herrmann@gmail.com> Date: Sat Apr 6 20:28:47 2013 +0200 Bluetooth: hidp: remove old session-management The old session-management always forced an l2cap error on the ctrl/intr channels when shutting down. The new session-management skips this, as we don't want to enforce channel policy on the caller. In other words, if user-space removes an HIDP device, the underlying channels (which are *owned* and *referenced* by user-space) are still left active. User-space needs to call shutdown(2) or close(2) to release them. Unfortunately, this does not work with idle-timeouts. There is no way to signal user-space that the HIDP layer has been stopped. The API simply does not support any event-passing except for poll(2). Hence, we restore old behavior and force EUNATCH on the sockets if the HIDP layer is disconnected due to idle-timeouts (behavior of explicit disconnects remains unmodified). User-space can still call getsockopt(..., SO_ERROR, ...) ..to retrieve the EUNATCH error and clear sk_err. Hence, the channels can still be re-used (which nobody does so far, though). Therefore, the API still supports the new behavior, but with this patch it's also compatible to the old implicit channel shutdown.

The change to bpa10x to use the h4_recv_buf helper added a dependency on BT_HCIUART. This was incorrectly added to Kconfig by adding a 'select' statement, which now in turn causes build failures when CONFIG_TTY is not set: warning: (BT_HCIBPA10X) selects BT_HCIUART which has unmet direct dependencies (NET && BT && TTY) vers/built-in.o: In function `hci_uart_tty_receive': fpga-mgr.c:(.text+0x282824): undefined reference to `tty_unthrottle' drivers/built-in.o: In function `hci_uart_tty_ioctl': fpga-mgr.c:(.text+0x282aa0): undefined reference to `n_tty_ioctl_helper' drivers/built-in.o: In function `hci_uart_flush': This replaces the 'select BT_HCIUART' dependency with 'depends on', which does not have this kind of problem. Alternatively, one could add 'depends on TTY', but avoiding 'select' on user-visible options is generally the preferred choice as that does not introduce the potential for dependency loops or incomplete dependency chains.

There are LE devices on the market that start off by announcing their public address and then once paired switch to using private address. To be interoperable with such devices we should simply trust the fact that we're receiving an IRK from them to indicate that they may use private addresses in the future. Instead, simply tie the persistency to the bonding/no-bonding information the same way as for LTKs and CSRKs. Signed-off-by:

Link interrupts are enabled in init_umac(), which is too early for us to process them since we do not yet have a valid PHY device pointer. On BCM7425 chips for instance, we will crash calling phy_mac_interrupt() because phydev is NULL. Fix this by moving the link interrupts enabling in bcmgenet_netif_start(), under a specific function: bcmgenet_link_intr_enable() and while at it, update the comments surrounding the code.

Pablo Neira Ayuso says: ==================== Netfilter/IPVS updates for net-next The following patchset contains Netfilter/IPVS updates for your net-next tree. Most relevantly, updates for the nfnetlink_log to integrate with conntrack, fixes for cttimeout and improvements for nf_queue core, they are: 1) Remove useless ifdef around static inline function in IPVS, from Eric W. Biederman. 2) Simplify the conntrack support for nfnetlink_queue: Merge nfnetlink_queue_ct.c file into nfnetlink_queue_core.c, then rename it back to nfnetlink_queue.c 3) Use y2038 safe timestamp from nfnetlink_queue. 4) Get rid of dead function definition in nf_conntrack, from Flavio Leitner. 5) Attach conntrack support for nfnetlink_log.c, from Ken-ichirou MATSUZAWA. This adds a new NETFILTER_NETLINK_GLUE_CT Kconfig switch that controls enabling both nfqueue and nflog integration with conntrack. The userspace application can request this via NFULNL_CFG_F_CONNTRACK configuration flag. 6) Remove unused netns variables in IPVS, from Eric W. Biederman and Simon Horman. 7) Don't put back the refcount on the cttimeout object from xt_CT on success. 8) Fix crash on cttimeout policy object removal. We have to flush out the cttimeout extension area of the conntrack not to refer to an unexisting object that was just removed. 9) Make sure rcu_callback completion before removing nfnetlink_cttimeout module removal. 10) Fix compilation warning in br_netfilter when no nf_defrag_ipv4 and nf_defrag_ipv6 are enabled. Patch from Arnd Bergmann. 11) Autoload ctnetlink dependencies when NFULNL_CFG_F_CONNTRACK is requested. Again from Ken-ichirou MATSUZAWA. 12) Don't use pointer to previous hook when reinjecting traffic via nf_queue with NF_REPEAT verdict since it may be already gone. This also avoids a deadloop if the userspace application keeps returning NF_REPEAT. 13) A bunch of cleanups for netfilter IPv4 and IPv6 code from Ian Morris. 14) Consolidate logger instance existence check in nfulnl_recv_config(). 15) Fix broken atomicity when applying configuration updates to logger instances in nfnetlink_log. 16) Get rid of the .owner attribute in our hook object. We don't need this anymore since we're dropping pending packets that have escaped from the kernel when unremoving the hook. Patch from Florian Westphal. 17) Remove unnecessary rcu_read_lock() from nf_reinject code, we always assume RCU read side lock from .call_rcu in nfnetlink. Also from Florian. 18) Use static inline function instead of macros to define NF_HOOK() and NF_HOOK_COND() when no netfilter support in on, from Arnd Bergmann. ==================== Signed-off-by: -

Sowmini found hang with rds-ping while testing RDS over TCP. Its a corner case and doesn't happen always. The issue is not reproducible with IB transport. Its clear from below dump why we see it with RDS TCP.

Commit db6526dc ("RDS: use rds_send_xmit() state instead of RDS_LL_SEND_FULL") which was trying to opportunistically finish the send request in same thread context. But because of above recursive lock hang with RDS TCP, the send work from rds_send_pong() needs to deferred to worker to avoid lock up. Given RDS ping is more of connectivity test than performance critical path, its should be ok even for transport like IB. Reported-by:

Before lightweight tunnels existed, it really didn't make sense to create a tunnel that was not fully specified, such as without a destination IP address - the resulting packets would go nowhere. However, with lightweight tunnels, the opposite is true - it doesn't make sense to require this information when it will be provided later on by the route. This loosens the requirements for this information. An alternative would be to allow the relaxed version only when COLLECT_METADATA is enabled. However, since there are several variations on this theme (such as NBMA tunnels in GRE), just dropping the restrictions seems the most consistent across tunnels and with the existing configuration.

At the time of commit fff32699 ("tcp: reflect SYN queue_mapping into SYNACK packets") we had little ways to cope with SYN floods. We no longer need to reflect incoming skb queue mappings, and instead can pick a TX queue based on cpu cooking the SYNACK, with normal XPS affinities. Note that all SYNACK retransmits were picking TX queue 0, this no longer is a win given that SYNACK rtx are now distributed on all cpus. Signed-off-by:

If OVS receives a packet from another namespace, then the packet should be scrubbed. However, people have already begun to rely on the behaviour that skb->mark is preserved across namespaces, so retain this one field. This is mainly to address information leakage between namespaces when using OVS internal ports, but by placing it in ovs_vport_receive() it is more generally applicable, meaning it should not be overlooked if other port types are allowed to be moved into namespaces in future.

Johan Hedberg says: ==================== pull request: bluetooth 2015-10-16 First of all, sorry for the late set of patches for the 4.3 cycle. We just finished an intensive week of testing at the Bluetooth UnPlugFest and discovered (and fixed) issues there. Unfortunately a few issues affect 4.3-rc5 in a way that they break existing Bluetooth LE mouse and keyboard support. The regressions result from supporting LE privacy in conjunction with scanning for Resolvable Private Addresses before connecting. A feature that has been tested heavily (including automated unit tests), but sadly some regressions slipped in. The UnPlugFest with its multitude of test platforms is a good battle testing ground for uncovering every corner case. The patches in this pull request focus only on fixing the regressions in 4.3-rc5. The patches look a bit larger since we also added comments in the critical sections of the fixes to improve clarity. I would appreciate if we can get these regression fixes to Linus quickly. Please let me know if there are any issues pulling. Thanks. ==================== Signed-off-by: -

BITS_RX_EN is an 'unsigned long' constant, so the ones complement of that has bits set that do not fit into a 32-bit variable on 64-bit architectures, which causes a harmless gcc warning: drivers/net/ethernet/hisilicon/hix5hd2_gmac.c: In function 'hix5hd2_port_disable': drivers/net/ethernet/hisilicon/hix5hd2_gmac.c:374:2: warning: large integer implicitly truncated to unsigned type [-Woverflow] writel_relaxed(~(BITS_RX_EN | BITS_TX_EN), priv->base + PORT_EN); This adds a cast to (u32) to tell gcc that the code is indeed fine.
