2015-10-19i40e: Fix basic support for X722 devicesAnjali Singhai3-6/+31
Acquire NVM, before issuing an AQ read nvm command for X722. We need to acquire the NVM before issuing an AQ read to the NVM otherwise we will get EBUSY from the FW. Also release when done. This fixes the two X722 issues with respect to eeprom checksum verify and reading NVM version info. With this patch in place, i40e driver will provide basic support for X722 devices.

2015-10-19i40e: Lock for VSI's MAC filter listKiran Patil4-56/+282
This patch introduces a spinlock which is to be used for synchronizing access to VSI's MAC filter list. This patch also synchronizes execution of other codepaths which are accessing VSI's MAC filter list with execution of service_task:sync_vsi_filters. In function i40e_add_vsi, copied out LAA MAC address instead of cloning MAC filter entry because only MAC address is needed to remove MAC VLAN filter from FW/HW.

Pablo Neira Ayuso says: ==================== Netfilter/IPVS updates for net-next The following patchset contains Netfilter/IPVS updates for your net-next tree. Most relevantly, updates for the nfnetlink_log to integrate with conntrack, fixes for cttimeout and improvements for nf_queue core, they are: 1) Remove useless ifdef around static inline function in IPVS, from Eric W. Biederman. 2) Simplify the conntrack support for nfnetlink_queue: Merge nfnetlink_queue_ct.c file into nfnetlink_queue_core.c, then rename it back to nfnetlink_queue.c 3) Use y2038 safe timestamp from nfnetlink_queue. 4) Get rid of dead function definition in nf_conntrack, from Flavio Leitner. 5) Attach conntrack support for nfnetlink_log.c, from Ken-ichirou MATSUZAWA. This adds a new NETFILTER_NETLINK_GLUE_CT Kconfig switch that controls enabling both nfqueue and nflog integration with conntrack. The userspace application can request this via NFULNL_CFG_F_CONNTRACK configuration flag. 6) Remove unused netns variables in IPVS, from Eric W. Biederman and Simon Horman. 7) Don't put back the refcount on the cttimeout object from xt_CT on success. 8) Fix crash on cttimeout policy object removal. We have to flush out the cttimeout extension area of the conntrack not to refer to an unexisting object that was just removed. 9) Make sure rcu_callback completion before removing nfnetlink_cttimeout module removal. 10) Fix compilation warning in br_netfilter when no nf_defrag_ipv4 and nf_defrag_ipv6 are enabled. Patch from Arnd Bergmann. 11) Autoload ctnetlink dependencies when NFULNL_CFG_F_CONNTRACK is requested. Again from Ken-ichirou MATSUZAWA. 12) Don't use pointer to previous hook when reinjecting traffic via nf_queue with NF_REPEAT verdict since it may be already gone. This also avoids a deadloop if the userspace application keeps returning NF_REPEAT. 13) A bunch of cleanups for netfilter IPv4 and IPv6 code from Ian Morris. 14) Consolidate logger instance existence check in nfulnl_recv_config(). 15) Fix broken atomicity when applying configuration updates to logger instances in nfnetlink_log. 16) Get rid of the .owner attribute in our hook object. We don't need this anymore since we're dropping pending packets that have escaped from the kernel when unremoving the hook. Patch from Florian Westphal. 17) Remove unnecessary rcu_read_lock() from nf_reinject code, we always assume RCU read side lock from .call_rcu in nfnetlink. Also from Florian. 18) Use static inline function instead of macros to define NF_HOOK() and NF_HOOK_COND() when no netfilter support in on, from Arnd Bergmann. ==================== Signed-off-by: David S.

2015-10-18RDS: fix rds-ping deadlock over TCP transportsantosh.shilimkar@oracle.com1-3/+2

Commit db6526dcb51b ("RDS: use rds_send_xmit() state instead of RDS_LL_SEND_FULL") which was trying to opportunistically finish the send request in same thread context. But because of above recursive lock hang with RDS TCP, the send work from rds_send_pong() needs to deferred to worker to avoid lock up. Given RDS ping is more of connectivity test than performance critical path, its should be ok even for transport like IB.

At the time of commit fff326990789 ("tcp: reflect SYN queue_mapping into SYNACK packets") we had little ways to cope with SYN floods. We no longer need to reflect incoming skb queue mappings, and instead can pick a TX queue based on cpu cooking the SYNACK, with normal XPS affinities. Note that all SYNACK retransmits were picking TX queue 0, this no longer is a win given that SYNACK rtx are now distributed on all cpus.

2015-10-18ipconfig: send Client-identifier in DHCP requestsLi RongQing2-1/+34
A dhcp server may provide parameters to a client from a pool of IP addresses and using a shared rootfs, or provide a specific set of parameters for a specific client, usually using the MAC address to identify each client individually. The dhcp protocol also specifies a client-id field which can be used to determine the correct parameters to supply when no MAC address is available. There is currently no way to tell the kernel to supply a specific client-id, only the userspace dhcp clients support this feature, but this can not be used when the network is needed before userspace is available such as when the root filesystem is on NFS. This patch is to be able to do something like "ip=dhcp,client_id_type, client_id_value", as a kernel parameter to enable the kernel to identify itself to the server.

2015-10-16netfilter: turn NF_HOOK into an inline functionArnd Bergmann2-4/+17
A recent change to the dst_output handling caused a new warning when the call to NF_HOOK() is the only used of a local variable passed as 'dev', and CONFIG_NETFILTER is disabled: net/ipv6/ip6_output.c: In function 'ip6_output': net/ipv6/ip6_output.c:135:21: warning: unused variable 'dev' [-Wunused-variable] The reason for this is that the NF_HOOK macro in this case does not reference the variable at all, and the call to dev_net(dev) got removed from the ip6_output function. To avoid that warning now and in the future, this changes the macro into an equivalent inline function, which tells the compiler that the variable is passed correctly but still unused. The dn_forward function apparently had the same problem in the past and added a local workaround that no longer works with the inline function. In order to avoid a regression, we have to also remove the #ifdef from decnet in the same patch.

In the newly introduced Spectrum switch ASIC, packets destined to not offloaded netdevs will be classified to special FIDs (vFIDs) in the device and flooded to the CPU port. The flooding table used is of type per-FID, which allows one to create different flooding domains for different vFIDs. While using a simple single-entry flood table is certainly sufficient at this point, we do plan to offload 802.1D bridges involving VLAN interfaces, thus making this change necessary. Add support for this flooding table type, by exposing the configuration of the number of tables from this type and their size.

2015-10-16net: introduce pre-change upper device notifierJiri Pirko2-0/+10
This newly introduced netdevice notifier is called before actual change upper happens. That provides a possibility for notifier handlers to know upper change will happen and react to it, including possibility to forbid the change. That is valuable for drivers which can check if the upper device linkage is supported and forbid that in case it is not. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-10-16 This series contains updates to e1000, e1000e, igb, igbvf, ixgbe, ixgbevf, i40e, i40evf and fm10k. Alex Duyck fixes the polling routine for i40e/i40evf were the NAPI budget for receive cleanup was being rounded up to 1 but the netpoll call was expecting no Rx to be processed as the budget passed was 0. Also cleaned up IN_NETPOLL flag that was not adding any value due to the receive cleanup was handled in NAPI. Added support for netpoll for i40evf as well. Jesse updates all of our drivers to use napi_complete_done() instead of napi_complete(), which allows us to use /sys/class/net/ethX/gro_flush_timeout. Added ethtool support to control and report the new Interrupt Limit register, since the XL710 hardware has a different interrupt moderation design that can support a limit of total interrupts per second per vector. Shannon cleans up startup log entries to cut down the number by putting a couple behind debug flags and combining others into single line. Added support to enable/disable printing VEB statistics via ethtool. Jingjing fixes a compile issue by adding const to functions that return strings that are not going to be modified. Greg Rose cleans up defines that were not used and were causing customer confusion. Greg Bowers adds support for setting a new bit in the Set Local LLDP MIB admin queue command Type field. Mitch fixes an issue where vlan_features field was set to the same value as netdev features field, but before the features were actually being set up, leaving the vlan_features empty. Resolve the issue by setting up the netdev features first, then mask out the VLAN feature bits when assigning vlan_features. Fixed VF init timing, where in some instances the VFs would fail to initialize the first time you loaded the driver. To correct this, increased the delay time for the init task and wait longer before giving up. v2: fix missing space in function header comment in patch 3, based on feedback from Sergei Shtylyov. ==================== Signed-off-by: David S.

2015-10-16i40e: increase AQ work limitMitch Williams1-1/+1
With 64 VFs, we can easily overwhelm the AQ on the PF if we have too low a limit on the number of AQ requests. This leads to ARQ overflow errors, and occasionally VFs that fail to initialize. Since we really only hit this condition on initial VF driver load, the requests that we process are lightweight, so this extra work doesn't cause problems for the PF driver.

2015-10-16i40evf: relax and stagger init timing a bitMitch Williams2-3/+3
On some devices, in some systems, in some configurations, the VFs would fail to initialize the first time you loaded the driver. To correct this, increase the delay time for the init task slightly, and wait longer before giving up. If we enable VFs and load the VF driver in the same kernel as the PF driver, we can totally overwhelm the PF driver with AQ requests because all of the instances try to initialize at the same time. To help alleviate this, stagger the initial scheduling of the init task using the PCIe function as a multiplier. We mask off the function to only three bits so no instance has to wait too long. With these two changes, initializing 128 VFs on a single device goes from four minutes to just a few seconds.

1000Base_T_Optical got added to the function that figures out what is supported when link is down but not when link is up. Add it in there too so that we display the correct information.
