2017-04-25bpf: map_get_next_key to return first key on NULLTeng Qin5-20/+50
When iterating through a map, we need to find a key that does not exist in the map so map_get_next_key will give us the first key of the map. This often requires a lot of guessing in production systems. This patch makes map_get_next_key return the first key when the key pointer in the parameter is NULL.

2017-04-25netvsc: fix calculation of available send sectionsstephen hemminger2-6/+4
My change (introduced in 4.11) to use find_first_clear_bit incorrectly assumed that the size argument was words, not bits. The effect was only a small limited number of the available send sections were being actually used. This can cause performance loss with some workloads. Since map_words is now used only during initialization, it can be on stack instead of in per-device data.

2017-04-25tipc: fix socket flow control accounting error at tipc_recv_streamParthasarathy Bhuvaragan1-1/+1
Until now in tipc_recv_stream(), we update the received unacknowledged bytes based on a stack variable and not based on the actual message size. If the user buffer passed at tipc_recv_stream() is smaller than the received skb, the size variable in stack differs from the actual message size in the skb. This leads to a flow control accounting error causing permanent congestion. In this commit, we fix this accounting error by always using the size of the incoming message.

2017-04-25ipv6: move stub initialization after ipv6 setup completionPaolo Abeni1-2/+4
The ipv6 stub pointer is currently initialized before the ipv6 routing subsystem: a 3rd party can access and use such stub before the routing data is ready. Moreover, such pointer is not cleared in case of initialization error, possibly leading to dangling pointers usage. This change addresses the above moving the stub initialization at the end of ipv6 init code.

2017-04-25net sched actions: Complete the JUMPX opcodeJamal Hadi Salim1-0/+25
per discussion at netconf/netdev: When we have an action that is capable of branching (example a policer), we can achieve a continuation of the action graph by programming a "continue" where we find an exact replica of the same filter rule with a lower priority and the remainder of the action graph. When you have 100s of thousands of filters which require such a feature it gets very inefficient to do two lookups. This patch completes a leftover feature of action codes. Its time has come. Example below where a user labels packets with a different skbmark on ingress of a port depending on whether they have/not exceeded the configured rate. This mark is then used to make further decisions on some egress port. #rate control, very low so we can easily see the effect sudo $TC actions add action police rate 1kbit burst 90k \ conform-exceed pipe/jump 2 index 10 # skbedit index 11 will be used if the user conforms sudo $TC actions add action skbedit mark 11 ok index 11 # skbedit index 12 will be used if the user does not conform sudo $TC actions add action skbedit mark 12 ok index 12 #lets bind the user .. sudo $TC filter add dev $ETH parent ffff: protocol ip prio 8 u32 \ match ip dst 127.0.0.8/32 flowid 1:10 \ action police index 10 \ action skbedit index 11 \ action skbedit index 12 #run a ping -f and see what happens.. # jhs@foobar:~$ sudo $TC -s filter ls dev $ETH parent ffff: protocol ip filter pref 8 u32 filter pref 8 u32 fh 800: ht divisor 1 filter pref 8 u32 fh 800::800 order 2048 key ht 800 bkt 0 flowid 1:10 (rule hit 2800 success 1005) match 7f000008/ffffffff at 16 (success 1005 ) action order 1: police 0xa rate 1Kbit burst 23440b mtu 2Kb action pipe/jump 2 overhead 0b ref 2 bind 1 installed 207 sec used 122 sec Action statistics: Sent 84420 bytes 1005 pkt (dropped 0, overlimits 721 requeues 0) backlog 0b 0p requeues 0 action order 2: skbedit mark 11 pass index 11 ref 2 bind 1 installed 204 sec used 122 sec Action statistics: Sent 60564 bytes 721 pkt (dropped 0, overlimits 0 requeues 0) backlog 0b 0p requeues 0 action order 3: skbedit mark 12 pass index 12 ref 2 bind 1 installed 201 sec used 122 sec Action statistics: Sent 23856 bytes 284 pkt (dropped 0, overlimits 0 requeues 0) backlog 0b 0p requeues 0 Not bad, about 28% non-conforming packets..

2017-04-25ASoC: intel: Fix PM and non-atomic crash in bytcr driversTakashi Iwai2-4/+2
The FE setups of Intel SST bytcr_rt5640 and bytcr_rt5651 drivers carry the ignore_suspend flag, and this prevents the suspend/resume working properly while the stream is running, since SST core code has the check of the running streams and returns -EBUSY. Drop these superfluous flags for fixing the behavior. Also, the bytcr_rt5640 driver lacks of nonatomic flag in some FE definitions, which leads to the kernel Oops at suspend/resume like: BUG: scheduling while atomic: systemd-sleep/3144/0x00000003 Call Trace: dump_stack+0x5c/0x7a __schedule_bug+0x55/0x70 __schedule+0x63c/0x8c0 schedule+0x3d/0x90 schedule_timeout+0x16b/0x320 ? del_timer_sync+0x50/0x50 ? sst_wait_timeout+0xa9/0x170 [snd_intel_sst_core] ? sst_wait_timeout+0xa9/0x170 [snd_intel_sst_core] ? remove_wait_queue+0x60/0x60 ? sst_prepare_and_post_msg+0x275/0x960 [snd_intel_sst_core] ? sst_pause_stream+0x9b/0x110 [snd_intel_sst_core] ....

2017-04-25ipvlan: use pernet operations and restrict l3s hooks to master netnsFlorian Westphal2-15/+70
commit 4fbae7d83c98c30efc ("ipvlan: Introduce l3s mode") added registration of netfilter hooks via nf_register_hooks(). This API provides the illusion of 'global' netfilter hooks by placing the hooks in all current and future network namespaces. In case of ipvlan the hook appears to be only needed in the namespace that contains the ipvlan master device (i.e., usually init_net), so placing them in all namespaces is not needed. This switches ipvlan driver to pernet operations, and then only registers hooks in namespaces where a ipvlan master device is set to l3s mode. Extra care has to be taken when the master device is moved to another namespace, as we might have to 'move' the netfilter hooks too. This is done by storing the namespace the ipvlan port was created in. On REGISTER event, do (un)register operations in the old/new namespaces. This will also allow removal of the nf_register_hooks() in a future patch. Cc: Mahesh Bandewar <[email protected]> Signed-off-by: Florian Westphal <[email protected]> Signed-off-by: David S.

This patch drops that reference count. Fixes: 260916dfb48c ("macvlan: Fix potential use-after free for...")

This patch adds the support of the PCAN-Chip USB, a stamp module for customer hardware designs, which communicates via USB 2.0 with the hardware. The integrated CAN controller supports the protocols CAN 2.0 A/B as well as CAN FD. The physical CAN connection is determined by external wiring. The Stamp module with its single-sided mounting and plated half-holes is suitable for automatic assembly. Note that the chip is equipped with the same logic than the PCAN-USB FD.

2017-04-25can: m_can: Enable TX FIFO Handling for M_CAN IP version >= v3.1.xMario Huettel1-29/+159
* Added defines for TX Event FIFO Element * Adapted ndo_start_xmit function. For versions >= v3.1.x it uses the TX FIFO to optimize the data throughput. It stores the echo skb at the same index as in the M_CAN's TX FIFO. The frame's message marker is set to this index. This message marker is received in the TX Event FIFO after the message was successfully transmitted. It is used to echo the correct echo skb back to the network stack. * Added m_can_echo_tx_event function. It reads all received message markers in the TX Event FIFO and loops back the corresponding echo skbs. * ISR checks for new TX Event Entry interrupt for version >= 3.1.x.

2017-04-25can: m_can: Enable M_CAN version dependent initializationMario Huettel1-71/+269
This patch adapts the initialization of the M_CAN. So it can be used with all versions >= 3.0.x. Changes: * Added version element to m_can_priv structure to hold M_CAN version. * Renamed bittiming structs for version 3.0.x * Added new bittiming structs for version >= 3.1.x * Function alloc_m_can_dev takes 2 new arguments. The TX FIFO size and the base address of the module. * Chip configuration for CAN_CTRLMODE_LOOPBACK is changed: Enabled CCCR_MON bit. In combination with TEST_LBCK it activates the internal loopback mode. Leaving CCCR_MON '0' results in external loopback mode. * Clocks are temporarily enabled by platform_propbe function in order to allow read access to the Core Release register and the Control Register. Registers are used to detect M_CAN version and optional Non-ISO Feature. Initialization of M_CAN for version >= 3.1.x: * TX FIFO of M_CAN is used to transmit frames. The driver does not need to stop the tx queue after each frame sent. * Initialization of TX Event FIFO is added. * NON-ISO is fixed for all M_CAN versions < 3.2.x. Version 3.2.x _can_ have the NISO (Non-ISO) bit which can switch the mode of the M_CAN to Non-ISO mode. This bit does not have to be writeable. Therefore it is checked. If it is writable Non-ISO support is added to the controllers supported CAN modes. New Functions: * Function to check the Core Release version. The read value determines the behaviour of the driver. * Function to check if the NISO bit for version >= 3.2.x is implemented.
