* net: diag: allow socket bytecode filters to match socket marksLorenzo Colitti2016-08-241-0/+6
| | | | | | | | | | | | | | | | This allows a privileged process to filter by socket mark when dumping sockets via INET_DIAG_BY_FAMILY. This is useful on systems that use mark-based routing such as Android. The ability to filter socket marks requires CAP_NET_ADMIN, which is consistent with other privileged operations allowed by the SOCK_DIAG interface such as the ability to destroy sockets and the ability to inspect BPF filters attached to packet sockets.

* net: dsa: rename switch operations structureVivien Didelot2016-08-241-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that the dsa_switch_driver structure contains only function pointers as it is supposed to, rename it to the more appropriate dsa_switch_ops, uniformly to any other operations structure in the kernel. No functional changes here, basically just the result of something like: s/dsa_switch_driver *drv/dsa_switch_ops *ops/g However keep the {un,}register_switch_driver functions and their dsa_switch_drivers list as is, since they represent the -- likely to be deprecated soon -- legacy DSA registration framework. In the meantime, also fix the following checks from checkpatch.pl to make it happy with this patch: CHECK: Comparison to NULL could be written "!ops" #403: FILE: net/dsa/dsa.c:470: + if (ops == NULL) { CHECK: Comparison to NULL could be written "ds->ops->get_strings" #773: FILE: net/dsa/slave.c:697: + if (ds->ops->get_strings != NULL) CHECK: Comparison to NULL could be written "ds->ops->get_ethtool_stats" #824: FILE: net/dsa/slave.c:785: + if (ds->ops->get_ethtool_stats != NULL) CHECK: Comparison to NULL could be written "ds->ops->get_sset_count" #835: FILE: net/dsa/slave.c:798: + if (ds->ops->get_sset_count != NULL) total: 0 errors, 0 warnings, 4 checks, 784 lines checked Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Acked-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.

| * net/mlx5: Implement RoCE LAG featureAviv Heller2016-08-181-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Available on dual port cards only, this feature keeps track, using netdev LAG events, of the bonding and link status of each port's PF netdev. When both of the card's PF netdevs are enslaved to the same bond/team master, and only them, LAG state is active. During LAG, only one IB device is present for both ports. In addition to the above, this commit includes FW commands used for managing the LAG, new facilities for adding and removing a single device by interface, and port remap functionality according to bond events. Please note that this feature is currently used only for mimicking Ethernet bonding for RoCE - netdevs functionality is not altered, and their bonding continues to be managed solely by bond/team driver.

Available only in LAG mode. - DESTROY_VPORT_LAG Ethernet flow steering returns to non-LAG behavior. Caps added: - lag_master Driver is in charge of managing the LAG.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prior to this patch we assumed that modify QP commands have the same layout. In ConnectX-4 for each QP transition there is a specific command and their layout can vary. e.g: 2err/2rst commands don't have QP context in their layout and before this patch we posted the QP context in those commands. Fortunately the FW only checks the suffix of the commands and executes them, while ignoring all invalid data sent after the valid command layout. This patch removes mlx5_modify_qp_mbox_in and changes mlx5_core_qp_modify to receive the required transition and QP context with opt_param_mask if needed. This way the caller is not required to provide the command inbox layout and it will be generated automatically. mlx5_core_qp_modify will generate the command inbox/outbox layouts according to the requested transition and will fill the requested parameters.

* | net_sched: properly handle failure case of tcf_exts_init()WANG Cong2016-08-221-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | After commit 22dc13c837c3 ("net_sched: convert tcf_exts from list to pointer array") we do dynamic allocation in tcf_exts_init(), therefore we need to handle the ENOMEM case properly.

* | qed: utilize FW 8.10.10.0Yuval Mintz2016-08-195-131/+442
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This new firmware for the qed* adpaters fixes several issues: - Better blocking of malicious VFs. - After FLR, Tx-switching [internal routing] of packets might be incorrect. - Deletion of unicast MAC filters would sometime have side-effect of corrupting the MAC filters configred for a device. It also contains fixes for future qed* drivers that *hopefully* would be sent for review in the near future. In addition, it would allow driver some new functionality, including: - Allowing PF/VF driver compaitibility with old drivers [running pre-8.10.5.0 firmware]. - Better debug facilities. This would also bump the qed* driver versions to 8.10.9.20. Signed-off-by: Yuval Mintz <Yuval.Mintz@qlogic.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* | rhashtable: Remove GFP flag from rhashtable_walk_initHerbert Xu2016-08-191-3/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The commit 8f6fd83c6c5ec66a4a70c728535ddcdfef4f3697 ("rhashtable: accept GFP flags in rhashtable_walk_init") added a GFP flag argument to rhashtable_walk_init because some users wish to use the walker in an unsleepable context. In fact we don't need to allocate memory in rhashtable_walk_init at all. The walker is always paired with an iterator so we could just stash ourselves there. This patch does that by introducing a new enter function to replace the existing init function. This way we don't have to churn all the existing users again.

* | bpf: get rid of cgroup helper related ifdefsDaniel Borkmann2016-08-181-0/+10
| | | | | | | | | | | | | | | | | | | | | | As recently discussed during the task_under_cgroup_hierarchy() addition, we should get rid of the ifdefs surrounding the bpf_skb_under_cgroup() helper. If related functionality is not built-in, the helper cannot be used anyway, which is also in line with what we do for all other helpers.

* | bpf: add bpf_skb_change_tail helperDaniel Borkmann2016-08-182-1/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This work adds a bpf_skb_change_tail() helper for tc BPF programs. The basic idea is to expand or shrink the skb in a controlled manner. The eBPF program can then rewrite the rest via helpers like bpf_skb_store_bytes(), bpf_lX_csum_replace() and others rather than passing a raw buffer for writing here. bpf_skb_change_tail() is really a slow path helper and intended for replies with f.e. ICMP control messages. Concept is similar to other helpers like bpf_skb_change_proto() helper to keep the helper without protocol specifics and let the BPF program mangle the remaining parts. A flags field has been added and is reserved for now should we extend the helper in future.

* | net: bgmac: support Ethernet core on BCM53573 SoCsRafał Miłecki2016-08-182-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | BCM53573 is a new series of Broadcom's SoCs. It's based on ARM and can be found in two packages (versions): BCM53573 and BCM47189. It shares some code with the Northstar family, but also requires some new quirks. First of all there can be up to 2 Ethernet cores on this SoC. If that is the case, they are connected to two different switch ports allowing some more complex/optimized setups. It seems the second unit doesn't come fully configured and requires some IRQ quirk. Other than that only the first core is connected to the PHY. For the second one we have to register fixed PHY (similarly to the Northstar), otherwise generic PHY driver would get some invalid info. This has been successfully tested on Tenda AC9 (BCM47189B0).
