Don't transition to the PF state on every strike after 'Path.Max.Retrans'. Per draft-ietf-tsvwg-sctp-failover-03 Section 5.1.6: Additional (PMR - PFMR) consecutive timeouts on a PF destination confirm the path failure, upon which the destination transitions to the Inactive state. As described in [RFC4960], the sender (i) SHOULD notify ULP about this state transition, and (ii) transmit heartbeats to the Inactive destination at a lower frequency as described in Section 8.3 of [RFC4960]. This also prevents sending SCTP_ADDR_UNREACHABLE to the user as the state bounces between SCTP_INACTIVE and SCTP_PF for each subsequent strike. Signed-off-by:

With commit cc9fa74e ("slip/slcan: added locking in wakeup function") a formerly missing locking was added to slip.c and slcan.c by Andre Naujoks. Alexander Stein contributed the fix 367525c8 ("can: slcan: Fix spinlock variant") as the kernel lock debugging advised to use spin_lock_bh() instead of just using spin_lock(). This fix has to be applied to the same code section in slip.c for the same reason too. Signed-off-by:

commit 813b3b5d (ipv4: Use caller's on-stack flowi as-is in output route lookups.) introduces another regression which is very similar to the problem of commit e6b45241 (ipv4: reset flowi parameters on route connect) wants to fix: Before we call ip_route_output_key() in sctp_v4_get_dst() to get a dst that matches a bind address as the source address, we have already called this function previously and the flowi parameters have been initialized including flowi4_oif, so when we call this function again, the process in __ip_route_output_key() will be different because of the setting of flowi4_oif, and we'll get a networking device which corresponds to the inputted flowi4_oif as the output device, this is wrong because we'll never hit this place if the previously returned source address of dst match one of the bound addresses. To reproduce this problem, a vlan setting is enough: # ifconfig eth0 up # route del default # vconfig add eth0 2 # vconfig add eth0 3 # ifconfig eth0.2 10.0.1.14 netmask 255.255.255.0 # route add default gw 10.0.1.254 dev eth0.2 # ifconfig eth0.3 10.0.0.14 netmask 255.255.255.0 # ip rule add from 10.0.0.14 table 4 # ip route add table 4 default via 10.0.0.254 src 10.0.0.14 dev eth0.3 # sctp_darn -H 10.0.0.14 -P 36422 -h 10.1.4.134 -p 36422 -s -I You'll detect that all the flow are routed to eth0.2(10.0.1.254).

This patch fixes the PTP Tx timestamp interrupt handler. The original code misinterpreted the interrupt handler design. We were clearing the ena_mask bit for the Timesync interrupts. This is done to indicate that the interrupt will be handled in a scheduled work item (instead of immediately) and that work item is responsible for re-enabling the interrupts. However, the Tx timestamp was being handled immediately and nothing was ever re-enabling it. This resulted in a single interrupt working for the life of the driver. This patch fixes the issue by instead clearing the bit from icr0 which is used to indicate that the interrupt was immediately handled and can be re-enabled right away. This patch also clears up a related issue due to writing the PRTTSYN_STAT_0 register, which was unintentionally clearing the cause bits for Timesync interrupts.

Marc Kleine-Budde says: ==================== this is a pull request for net/master, for the v3.15 release cycle, consisting of 26 patches. Thomas Gleixner contributes 21 patches for the c_can driver, which address several shortcomings in the driver like hardware initialisation, concurrency, message ordering and poor performance. Two patches Oliver Hartkopp, one adds a missing lock to the sja1000_isa driver, the other one fixes the return value in the generic bit time configuration function. And finally a patch by Alexander Stein, that fixes the slcan driver to use the correct spinlock variant. To make it 26 patches, Wolfgang Grandegger patch for the c_can_pci driver, which enables the bus master only for MSI and a patch by Wolfram Sang, which converts the 'instance' in the c_can driver to the proper type. ==================== Signed-off-by: -

Vince Bridgers says: ==================== This series of patches addresses a handful of issues found in testing and reported by users of the Altera Triple Speed Ethernet soft IP. The patches address the following issues (in summary) 1) The SGDMA soft IP was found to incorrectly process receive packets when the target physical address of the receive buffer was on a boundary that's not 32-bit aligned. One of the patches addresses this issue. 2) The pause quanta was not being set by the driver, one patch of this series sets the pause quanta to the IEEE defined default value since the hardware reset value is 0. 3) An issue in a error recovery path of the probe routine caused a kernel panic in the event a phy was probed and could not be found. A patch addresses this issue. 4) A change was made to the driver name for Ethtool support, and comments added to support an addition to Ethtool to support the Altera Triple Speed Ethernet controller. ==================== Signed-off-by: -

This patch works around a recently discovered unaligned receive dma problem with the Altera SGMDA. The Altera SGDMA component cannot be configured to DMA data to unaligned addresses for receive packet operations from the Triple Speed Ethernet component because of a potential data transfer corruption that can occur. This patch addresses this issue by utilizing the shift 16 bits feature of the Altera Triple Speed Ethernet component and modifying the receive buffer physical addresses accordingly such that the target receive DMA address is always aligned on a 32-bit boundary.

Starting with commit 2dc33bbc "bnx2x: Remove the sriov VFOP mechanism", the bnx2x started enforcing vlan credits for all vlan configurations. This exposed 2 issues: - Vlan credits are not returned once a VF is removed; this causes a leak of credits, and eventually will lead to VFs with no vlan credits. - A vlan credit must be set aside for the Hypervisor to use, and should not be visible to the VF. Although linux VFs at the moment do not support vlan configuration [from the VF side] which causes them to be resilient to this sort of issue, Windows VF over linux hypervisors might fail to load as the vlan credits become depleted.

When the ipv6 fib changes during a table dump, the walk is restarted and the number of nodes dumped are skipped. But the existing code doesn't advance to the next node after a node is skipped. This can cause the dump to loop or produce lots of duplicates when the fib is modified during the dump. This change advances the walk to the next node if the current node is skipped after a restart.

When accessing the SJA1000 controller registers in the indirect access mode, writing the register number and reading/writing the data has to be an atomic attempt. As the sja1000_isa driver is an old style driver with a fixed number of instances the locking variable depends on the same index like all the other configuration elements given on the module command line. As a positive side effect dev->dev_id is populated by the instance index, which was missing in 3e66d013 ("can: populate netdev::dev_id for udev discrimination"). Reported-by:

Mark suggested to use one IF for the softirq and the other for the xmit function to avoid the xmit lock. That requires to write the frame into the interface first, then handle the echo skb and store the dlc before committing the TX request to the message ram. We use an atomic to handle the active buffers instead of reading the MSGVAL register as thats way faster especially on PCH/x86. Suggested-by:
