* rxrpc: Note a successfully aborted kernel operationDavid Howells2017-04-062-5/+9
| | | | | | | | | | Make rxrpc_kernel_abort_call() return an indication as to whether it actually aborted the operation or not so that kafs can trace the failure of the operation. Note that 'success' in this context means changing the state of the call, not necessarily successfully transmitting an ABORT packet. Signed-off-by: David Howells <dhowells@redhat.com>
* rxrpc: Use negative error codes in rxrpc_call structDavid Howells2017-04-0610-33/+33
| | | | | | | | Use negative error codes in struct rxrpc_call::error because that's what the kernel normally deals with and to make the code consistent. We only turn them positive when transcribing into a cmsg for userspace recvmsg. Signed-off-by: David Howells <dhowells@redhat.com>
* bonding: attempt to better support longer hw addressesJarod Wilson2017-04-064-68/+108
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | People are using bonding over Infiniband IPoIB connections, and who knows what else. Infiniband has a hardware address length of 20 octets (INFINIBAND_ALEN), and the network core defines a MAX_ADDR_LEN of 32. Various places in the bonding code are currently hard-wired to 6 octets (ETH_ALEN), such as the 3ad code, which I've left untouched here. Besides, only alb is currently possible on Infiniband links right now anyway, due to commit 1533e7731522, so the alb code is where most of the changes are. One major component of this change is the addition of a bond_hw_addr_copy function that takes a length argument, instead of using ether_addr_copy everywhere that hardware addresses need to be copied about. The other major component of this change is converting the bonding code from using struct sockaddr for address storage to struct sockaddr_storage, as the former has an address storage space of only 14, while the latter is 128 minus a few, which is necessary to support bonding over device with up to MAX_ADDR_LEN octet hardware addresses. Additionally, this probably fixes up some memory corruption issues with the current code, where it's possible to write an infiniband hardware address into a sockaddr declared on the stack. Lightly tested on a dual mlx4 IPoIB setup, which properly shows a 20-octet hardware address now: $ cat /proc/net/bonding/bond0 Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011) Bonding Mode: fault-tolerance (active-backup) (fail_over_mac active) Primary Slave: mlx4_ib0 (primary_reselect always) Currently Active Slave: mlx4_ib0 MII Status: up MII Polling Interval (ms): 100 Up Delay (ms): 100 Down Delay (ms): 100 Slave Interface: mlx4_ib0 MII Status: up Speed: Unknown Duplex: Unknown Link Failure Count: 0 Permanent HW addr: 80:00:02:08:fe:80:00:00:00:00:00:00:e4:1d:2d:03:00:1d:67:01 Slave queue ID: 0 Slave Interface: mlx4_ib1 MII Status: up Speed: Unknown Duplex: Unknown Link Failure Count: 0 Permanent HW addr: 80:00:02:09:fe:80:00:00:00:00:00:01:e4:1d:2d:03:00:1d:67:02 Slave queue ID: 0 Also tested with a standard 1Gbps NIC bonding setup (with a mix of e1000 and e1000e cards), running LNST's bonding tests.

* sfc: don't insert mc_list on low-latency firmware if it's too longEdward Cree2017-04-061-2/+8
| | | | | | | | | | | | | | | | If the mc_list is longer than 256 addresses, we enter mc_promisc mode. If we're in mc_promisc mode and the firmware doesn't support cascaded multicast, normally we also insert our mc_list, to prevent stealing by another VI. However, if the mc_list was too long, this isn't really helpful - the MC groups that didn't fit in the list can still get stolen, and having only some of them stealable will probably cause more confusing behaviour than having them all stealable. Since inserting 256 multicast filters takes a long time and can lead to MCDI state machine timeouts, just skip the mc_list insert in this overflow condition.

First patch introduces minimal speed and duplex reporting using the information directly provided in PCI BAR0 memory. Next few changes deal with the need to refresh port state read from the service process and patch 6 finally uses that information to provide link speed and duplex. Patches 7 and 8 add auto negotiation and port type reporting. Remaining changes provide the set support for speed and auto negotiation. An upcoming series will also add port splitting support via devlink. Quite a bit of churn in this series is caused by the fact that currently port speed and split changes will usually require a reboot to take effect. Current service process code is not capable of performing MAC reinitialization after chip has been passing traffic. To make sure user is aware of this limitation we refuse the configuration unless netdev is down, print warning to the logs and if configuration was performed but did take effect we unregister the netdev. Service process has a "reboot needed" sticky bit, so reloading the driver will not bring the netdev back. Note that there is a helper in patch 13 which is marked as __always_inline, because the FIELD_* macros require the parameters to be known at compilation time. I hope that is OK. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Also when speed and duplex settings for a link are updated during a link-event, the link-status should not be changed to invoke correct transition logic.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current code enables up to the maximum MSIX vectors in the PCIE config space without considering the max completion rings available. An MSIX vector is only useful when it has an associated completion ring, so it is better to cap it. Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S.

| * | bnxt_en: Use short TX BDs for the XDP TX ring.Michael Chan2017-04-051-14/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | No offload is performed on the XDP_TX ring so we can use the short TX BDs. This has the effect of doubling the size of the XDP TX ring so that it now matches the size of the rx ring by default. Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mac loopback self test operates in polling mode. To support that, we need to add functions to open and close the NIC half way. The half open mode allows the rings to operate without IRQ and NAPI. We use the XDP transmit function to send the loopback packet.
