* net: systemport: Fix software statistics for SYSTEMPORT LiteFlorian Fainelli2017-08-091-0/+4
| | | | | | | | | | | With SYSTEMPORT Lite we have holes in our statistics layout that make us skip over the hardware MIB counters, bcm_sysport_get_stats() was not taking that into account resulting in reporting 0 for all SW-maintained statistics, fix this by skipping accordingly.

* net/mlx4_en: don't set CHECKSUM_COMPLETE on SCTP packetsDavide Caratti2017-08-081-11/+18
| | | | | | | | | | | | | | | if the NIC fails to validate the checksum on TCP/UDP, and validation of IP checksum is successful, the driver subtracts the pseudo-header checksum from the value obtained by the hardware and sets CHECKSUM_COMPLETE. Don't do that if protocol is IPPROTO_SCTP, otherwise CRC32c validation fails.

* mlxsw: spectrum_switchdev: Release multicast groups during finiIdo Schimmel2017-08-041-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | Each multicast group (MID) stores a bitmap of ports to which a packet should be forwarded to in case an MDB entry associated with the MID is hit. Since the initial introduction of IGMP snooping in commit 3a49b4fde2a1 ("mlxsw: Adding layer 2 multicast support") the driver didn't correctly free these multicast groups upon ungraceful situations such as the removal of the upper bridge device or module removal. The correct way to fix this is to associate each MID with the bridge ports member in it and then drop the reference in case the bridge port is destroyed, but this will result in a lot more code and will be fixed in net-next. For now, upon module removal, traverse the MID list and release each one.

| | | | | | | | | | | | | | | | | | | Some operations in the bridge driver such as MDB deletion are preformed in an atomic context and thus deferred to a process context by the switchdev infrastructure. Therefore, by the time the operation is performed by the underlying device driver it's possible the bridge port context is already gone. This is especially true for removal flows, but theoretically can also be invoked during addition. Remove the warnings in such situations and return normally.

| | | | | | | | | | | | | | SCRQ resources are freed during renegotiation, but they are not re-allocated afterwards due to some changes in the initialization process. Fix that by re-allocating the memory after renegotation. SCRQ's can also be freed if a server capabilities request fails.

| | | | | | | | | | | | | | | | | | Now the call chain cpts_find_ts() |- cpts_fifo_read(cpts, CPTS_EV_PUSH) will stop reading CPTS FIFO if PUSH event is found. But this is not expected and CPTS FIFI should be completely drained here. This is most probably copy-paste error and it has no negative impact as CPTS_EV_PUSH should not be present in FIFO without TS_PUSH request and cpts_systim_read() and cpts_find_ts() synchronized by spin_lock. Correct above by calling cpts_fifo_read() with -1 parameter, so it will read all CPTS event from FIFO. Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: David S.

* net: ethernet: ti: cpts: fix tx timestamping timeoutGrygorii Strashko2017-08-012-2/+83
| | | | | | | | | | | | | | | | | | | | | With the low speed Ethernet connection CPDMA notification about packet processing can be received before CPTS TX timestamp event, which is set when packet actually left CPSW while cpdma notification is sent when packet pushed in CPSW fifo. As result, when connection is slow and CPU is fast enough TX timestamping is not working properly. Fix it, by introducing TX SKB queue to store PTP SKBs for which Ethernet Transmit Event hasn't been received yet and then re-check this queue with new Ethernet Transmit Events by scheduling CPTS overflow work more often (every 1 jiffies) until TX SKB queue is not empty. Side effect of this change is: - User space tools require to take into account possible delay in TX timestamp processing (for example ptp4l works with tx_timestamp_timeout=400 under net traffic and tx_timestamp_timeout=25 in idle).

* net: ethernet: ti: cpts: convert to use ptp auxiliary workerGrygorii Strashko2017-08-012-15/+13
| | | | | | | | | | | | | | There could be significant delay in CPTS work schedule under high system load and on -RT which could cause CPTS misbehavior due to internal counter overflow. Usage of own kthread_worker allows to avoid such kind of issues and makes it possible to tune priority of CPTS kthread_worker thread on -RT (thread name "cpts"). Hence, the CPTS driver is converted to use PTP auxiliary worker as PHC subsystem implements such functionality in a generic way now.

| | | | | | | | | | | We had reports of 50us not being sufficient to reset the MAC, thus hitting the "Hardware reset failed" error bringing the interface up on some AST2400 based machines. This bumps the timeout to 200us. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* net: stmmac: Adjust dump offset of DMA registers for ethtoolThor Thayer2017-07-244-2/+10
| | | | | | | | | | | | | The commit fbf68229ffe7 ("net: stmmac: unify registers dumps methods") in the Linux kernel modified the register dump to store the DMA registers at the DMA register offset (0x1000) but ethtool (stmmac.c) looks for the DMA registers after the MAC registers which is offset 55. This patch copies the DMA registers from the higher offset to the offset where ethtool expects them. Signed-off-by: Thor Thayer <thor.thayer@linux.intel.com> Signed-off-by: David S.

* mlxsw: spectrum_router: Don't offload routes next in listIdo Schimmel2017-07-241-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | Each FIB node holds a linked list of routes sharing the same prefix and length. In the case of IPv4 it's ordered according to table ID, metric and TOS and only the first route in the list is actually programmed to the device. In case a gatewayed route is added somewhere in the list, then after its nexthop group will be refreshed and become valid (due to the resolution of its gateway), it'll mistakenly overwrite the existing entry. Example: 192.168.200.0/24 dev enp3s0np3 scope link metric 1000 offload 192.168.200.0/24 via 192.168.100.1 dev enp3s0np3 metric 1000 offload Both routes are marked as offloaded despite the fact only the first one should actually be present in the device's table. When refreshing the nexthop group, don't write the route to the device's table unless it's the first in its node.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Push the request_irq function to the end of probe so as to ensure all the required fields are populated in the event of an ISR getting executed right after requesting the irq. Currently while loading the crash kernel a crash was seen as soon as devm_request_threaded_irq was called. This was due to n->poll being NULL which is called as part of net_rx_action function.

| * net: tehuti: don't process data if it has not been copied from userspaceColin Ian King2017-07-191-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The array data is only populated with valid information from userspace if cmd != SIOCDEVPRIVATE, other cases the array contains garbage on the stack. The subsequent switch statement acts on a subcommand in data[0] which could be any garbage value if cmd is SIOCDEVPRIVATE which seems incorrect to me. Instead, just return EOPNOTSUPP for the case where cmd == SIOCDEVPRIVATE to avoid this issue. As a side note, I suspect that the original intention of the code was for this ioctl to work just for cmd == SIOCDEVPRIVATE (and the current logic is reversed). However, I don't wont to change the current semantics in case any userspace code relies on this existing behaviour.

| * net: bcmgenet: Free skb after last Tx fragDoug Berger2017-07-152-60/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the skb is attached to the first control block of a fragmented skb it is possible that the skb could be freed when reclaiming that control block before all fragments of the skb have been consumed by the hardware and unmapped. This commit introduces first_cb and last_cb pointers to the skb control block used by the driver to keep track of which transmit control blocks within a transmit ring are the first and last ones associated with the skb. It then splits the bcmgenet_free_cb() function into transmit (bcmgenet_free_tx_cb) and receive (bcmgenet_free_rx_cb) versions that can handle the unmapping of dma mapped memory and cleaning up the corresponding control block structure so that the skb is only freed after the last associated transmit control block is reclaimed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In case we fail to map a single fragment, we would be leaving the transmit ring populated with stale entries. This commit introduces the helper function bcmgenet_put_txcb() which takes care of rewinding the per-ring write pointer back to where we left. It also consolidates the functionality of bcmgenet_xmit_single() and bcmgenet_xmit_frag() into the bcmgenet_xmit() function to make the unmapping of control blocks cleaner.
