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:

Sending diagnostic messages directly to the monitor socket might cause issues for devices processing their messages in interrupt context. So instead of trying to directly forward them, queue them up with the other HCI packets and lets them be processed by the sockets at the same time. 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.

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.

this patch fixes the bug triggered timeout sequence. when the connective ports cannot accept the packets with higher speed, they will send out the pause frame to the Soc's mac. At that time, the driver resets the relevant of the Soc, then it causes the packets cannot be sent out immediately. this patch fixes the issue. Signed-off-by:

before this patch, hns driver only permits user to set the net device by using ethtool -s when the device is link up. it is obviously not so good. it needs to be set no matter it is link up or down. so this patch fixes this issue. Signed-off-by:

The 'bcm-phy-lib.c', added as a part of the commit "net: phy: Add Broadcom phy library for common interfaces" was missing the module license. This was causing an issue when the library is built as a module; "module license 'unspecified' taints kernel". This patch fixes the issue by adding the module license, author and description to the bcm-phy-lib.c file. Fixes: a1cba561 ("net: phy: Add Broadcom phy library for common interfaces") Signed-off-by:

netlink_dump() allocates skb based on the calculated min_dump_alloc or a per socket max_recvmsg_len. min_alloc_size is maximum space required for any single netdev attributes as calculated by rtnl_calcit(). max_recvmsg_len tracks the user provided buffer to netlink_recvmsg. It is capped at 16KiB. The intention is to avoid small allocations and to minimize the number of calls required to obtain dump information for all net devices. netlink_dump packs as many small messages as could fit within an skb that was sized for the largest single netdev information. The actual space available within an skb is larger than what is requested. It could be much larger and up to near 2x with align to next power of 2 approach. Allowing netlink_dump to use all the space available within the allocated skb increases the buffer size a user has to provide to avoid truncaion (i.e. MSG_TRUNG flag set). It was observed that with many VLANs configured on at least one netdev, a larger buffer of near 64KiB was necessary to avoid "Message truncated" error in "ip link" or "bridge [-c[ompressvlans]] vlan show" when min_alloc_size was only little over 32KiB. This patch trims skb to allocated size in order to allow the user to avoid truncation with more reasonable buffer size. Signed-off-by:

A dhcp server may provide parameters to a client from a pool of IP addresses and using a shared rootfs, or provide a specific set of parameters for a specific client, usually using the MAC address to identify each client individually. The dhcp protocol also specifies a client-id field which can be used to determine the correct parameters to supply when no MAC address is available. There is currently no way to tell the kernel to supply a specific client-id, only the userspace dhcp clients support this feature, but this can not be used when the network is needed before userspace is available such as when the root filesystem is on NFS. This patch is to be able to do something like "ip=dhcp,client_id_type, client_id_value", as a kernel parameter to enable the kernel to identify itself to the server. Signed-off-by:
