In preparation for multipath RDS, split the rds_connection structure into a base structure, and a per-path struct rds_conn_path. The base structure tracks information and locks common to all paths. The workqs for send/recv/shutdown etc are tracked per rds_conn_path. Thus the workq callbacks now work with rds_conn_path. This commit allows for one rds_conn_path per rds_connection, and will be extended into multiple conn_paths in subsequent commits.

Make sure that dctcp_get_info() returns only the size of the info->dctcp struct that it zeroes out and fills in. Previously it had been returning the size of the enclosing tcp_cc_info union, sizeof(*info). There is no problem yet, but that union that may one day be larger than struct tcp_dctcp_info, in which case the TCP_CC_INFO code might accidentally copy uninitialized bytes from the stack.

Merge tag 'rxrpc-rewrite-20160613' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs David Howells says: ==================== rxrpc: Rename rxrpc source files Here's the next part of the AF_RXRPC rewrite. In this set I rename some of the files in the net/rxrpc/ directory and adjust the Makefile and ar-internal.h to reflect the changes. The aim is twofold: (1) Remove the "ar-" prefix on those files that have it as it's not really useful, especially now that I'm building rxkad in. (2) To aid splitting the local, peer, connection and call handling code into separate files for object and event handling in future patches by making it easier to come up with new filenames. There are two commits: (1) The first commit does a bunch of renames of .c files and alters the Makefile. ar-internal.h isn't renamed at this time to avoid having to change the contents of the files being renamed. (2) The second commit changes the section label comments in ar-internal.h to reflect the changed filenames and reorders the file so that the sections are back in filename order. The patches can be found here also: http://git.kernel.org/cgit/linux/kernel/git/dhowells/linux-fs.git/log/?h=rxrpc-rewrite Tagged thusly: git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs.git rxrpc-rewrite-20160613 ==================== Signed-off-by: David S.

Move calling set_speed() from open() to rtl_hw_phy_work_func_t(). Then, we would set the default speed only for first initialization or after resuming. Besides, the set_speed() could handle the flag of PHY_RESET which would be set in rtl_ops.hw_phy_cfg(). Signed-off-by: Hayes Wang <hayeswang@realtek.com> Signed-off-by: David S.

Move the settings of PHY to a work queue and schedule it after rtl_ops.init(). There are some reasons for this. First, the settings are only needed for the first time initialization or after the power down occurs. Second, the settings are independent with the others. Last, the settings may take more time than the others. Leave they in probe() or open() may delay the following flows. Signed-off-by: Hayes Wang <hayeswang@realtek.com> Signed-off-by: David S.

Some cards do not support autoneg. The current code does not prevent the user from enabling autoneg with ethtool on such cards, causing confusion. Firmware provides the autoneg capability information and we just need to store it in the support_auto_speeds field in bnxt_link_info struct.

The PF can setup a default VLAN for a VF. The default VLAN tag is automatically inserted and stripped without the knowledge of the stack running on the VF. The VF driver needs to know that default VLAN is enabled as VLAN acceleration on the RX side is no longer supported. Call netdev_update_features() to fix up the VLAN features as necessary. Also, VLAN strip mode must be enabled to strip out the default VLAN tag. Only allow VF default VLAN to be set if the firmware spec is >= 1.2.1.

The commit e858fae2 ("virtio_net: use common code for virtio_net_hdr and skb GSO conversion") replaced the tun code for header manipulation with the generic helpers. While doing so, it implictly moved the skb_partial_csum_set() invocation after eth_type_trans(), which invalidate the current gso start/offset values. Fix it by moving the helper invocation before the mac pulling.

Rename files matching net/rxrpc/ar-*.c to get rid of the "ar-" prefix. This will aid splitting those files by making easier to come up with new names. Note that the not all files are simply renamed from ar-X.c to X.c. The following exceptions are made: (*) ar-call.c -> call_object.c ar-ack.c -> call_event.c call_object.c is going to contain the core of the call object handling. Call event handling is all going to be in call_event.c. (*) ar-accept.c -> call_accept.c Incoming call handling is going to be here. (*) ar-connection.c -> conn_object.c ar-connevent.c -> conn_event.c The former file is going to have the basic connection object handling, but there will likely be some differentiation between client connections and service connections in additional files later. The latter file will have all the connection-level event handling. (*) ar-local.c -> local_object.c This will have the local endpoint object handling code. The local endpoint event handling code will later be split out into local_event.c. (*) ar-peer.c -> peer_object.c This will have the peer endpoint object handling code. Peer event handling code will be placed in peer_event.c (for the moment, there is none). (*) ar-error.c -> peer_event.c This will become the peer event handling code, though for the moment it's actually driven from the local endpoint's perspective. Note that I haven't renamed ar-transport.c to transport_object.c as the intention is to delete it when the rxrpc_transport struct is excised. The only file that actually has its contents changed is net/rxrpc/Makefile. net/rxrpc/ar-internal.h will need its section marker comments updating, but I'll do that in a separate patch to make it easier for git to follow the history across the rename. I may also want to rename ar-internal.h at some point - but that would mean updating all the #includes and I'd rather do that in a separate step. Signed-off-by: David Howells <dhowells@redhat.com.

sch_atm returns this when TC_ACT_SHOT classification occurs. But all other schedulers that use tc_classify (htb, hfsc, drr, fq_codel ...) return NET_XMIT_SUCCESS | __BYPASS in this case so just do that in atm. BATMAN uses it as an intermediate return value to signal forwarding vs. buffering, but it did not return POLICED to callers outside of BATMAN.

Eric Dumazet says: ==================== net_sched: remove qdisc_is_throttled() HTB, CBQ and HFSC pay a very high cost updating the qdisc 'throttled' status that nothing but CBQ seems to use. CBQ usage is flaky anyway, since no qdisc ->enqueue() updates the 'throttled' qdisc status. This looks like some 'optimization' that actually cost more than code without the optimization, and might cause latency issues with CBQ. In my tests, I could achieve a 8 % performance increase in TCP_RR workload through HTB qdisc, in presence of throttled classes, and 5 % without throttled classes. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

__QDISC_STATE_THROTTLED bit manipulation is rather expensive for HTB and few others. I already removed it for sch_fq in commit f2600cf0 ("net: sched: avoid costly atomic operation in fq_dequeue()") and so far nobody complained. When one ore more packets are stuck in one or more throttled HTB class, a htb dequeue() performs two atomic operations to clear/set __QDISC_STATE_THROTTLED bit, while root qdisc lock is held. Removing this pair of atomic operations bring me a 8 % performance increase on 200 TCP_RR tests, in presence of throttled classes. This patch has no side effect, since nothing actually uses disc_is_throttled() anymore. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>

So far no qdisc ever unset the throttled bit at enqueue() time, so CBQ usage of qdisc_is_throttled() was flaky. Since __QDISC_STATE_THROTTLED set/unset is way too expensive considering that only CBQ was eventually caring for this status, it would make sense to implement a Qdisc ops ->is_throttled() if we find that this is needed.

Pramod Kumar says: ==================== Add MDIO bus multiplexer support for iProc SoCs Broadcom iProc based SoCs use a MDIO bus multiplexer where child buses could be internal as well external to SoCs. These buses could supports MDIO transaction compatible to C-22/C-45. Broadcom MDIO bus multiplexer is an integrated multiplexer where child bus selection and mdio transaction logic lies inside multiplexer itself. To accommodate this multiplexer in existing mux framework below changes were required- 1. Passed MDIO parent bus via mdio_mux_init to MDIO mux framework. This patch set includes MDIO bus multiplexer driver along with above framework change. It includes one external bus node having Ethernet PHY attached and two internal bus node holding PCIe PHYs. This patch series is based on v4.7-rc1 and is available from github- repo: https://github.com/Broadcom/arm64-linux.git branch:mdio-mux-v5 -Changes from v4: - disabled PCIe PHYs from dtsi and enabled in dts file. -Changes from v3: - Unregister and free the parent MDIO bus. - rebased on net-next/master branch. Reason for resend: -Rebased on v4.7-rc1 Changes from v2: -Addressed Rob's comments in this patch regarding typo/grammers. -Addressed David's comments regarding local variables order. -Removed property "mdio-integrated-mux" and used mdiobus_register() in place of of_mdiobus_regsiter(). -removed usage of IS_ERR_OR_NULL to IS_ERR in PCIe PHY driver. Changes from v1: - stop using "brcm,is_c45" from bus node as suggested by Andrew. MDIO PHY driver will logically OR MII_ADDR_C45 into the address when issues any C45 MDIO read/write transaction. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
