2017-11-01cxgb4: add support to create hash-filters via tc-flower offloadKumar Sanghvi3-5/+161
Determine whether the flow classifies as exact-match with respect to 4-tuple and configured tuple mask in hw. If successfully classified as exact-match, offload the flow as hash-filter in hw.

2017-11-01cxgb4: convert flower table to use rhashtableKumar Sanghvi4-36/+82
T6 supports ~500K hash filters and can theoretically climb up to ~1 million hash filters. Preallocated hash table is not efficient in terms of memory usage. So, use rhashtable instead which gives the flexibility to grow based on usage.

2017-11-01cxgb4: add support to create hash filtersKumar Sanghvi6-50/+562
Add support to create hash (exact-match) filters based on the value of 'hash' field in ch_filter_specification. Allocate SMT/L2T entries if DMAC-rewrite/SMAC-rewrite is requested. Allocate CLIP entry in case of IPv6 filter. Use cpl_act_open_req[6] to send hash filter create request to hw. Also, the filter tuple is calculated as part of sending this request. Hash-filter reply is processed on getting cpl_act_open_rpl. In case of success, various bits/fields in filter-tcb are set per filter requirement, such as enabling filter hitcnts, and/or various header rewrite operations, such as VLAN-rewrite, NAT or (L3/L4)-rewrite, and SMAC/DMAC-rewrite. In case of failure, clear the filter entry and release any hw resources occupied by it. The patch also moves the functions set_tcb_field, set_tcb_tflag and configure_filter_smac towards beginning of file.

2017-11-01net: mvpp2: simplify the Tx desc set DMA logicAntoine Tenart1-26/+13
Two functions were always used to set the DMA addresses in Tx descriptors, because this address is split into a base+offset in the descriptors. A mask was used to come up with the base and offset addresses and two functions were called, mvpp2_txdesc_dma_addr_set() and mvpp2_txdesc_offset_set().

This patch reworks FIB rule handling to return a message to the user: $ ip ru add pref 99 from all to 8.8.8.8 table 11 Error: spectrum: FIB rules not supported. Aborting offload. spectrum currently only checks whether the fib rule is a default rule or an l3mdev rule, both of which it knows how to handle. Any other it aborts FIB offload. Move the processing to check the rule type inline with the user request. If the rule is an unsupported one, then a work queue entry is used to abort the offload.

2017-11-01bpf: reduce verifier memory consumptionAlexei Starovoitov1-4/+4
the verifier got progressively smarter over time and size of its internal state grew as well. Time to reduce the memory consumption. Before: sizeof(struct bpf_verifier_state) = 6520 After: sizeof(struct bpf_verifier_state) = 896 It's done by observing that majority of BPF programs use little to no stack whereas verifier kept all of 512 stack slots ready always. Instead dynamically reallocate struct verifier state when stack access is detected. Runtime difference before vs after is within a noise. The number of processed instructions stays the same.

git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: ==================== mlx5-updates-2017-10-31 mlx5e stats groups This series from Kamal introduces an important refactoring for mlx5e stats handling, which groups the stats into generic groups structure which allows to control the behavior and stats reporting per group in a modular way. In the first patch Kamal introduces a new data type "mlx5e_stats_grp" This change defines a new API to create a group of stats and simplifies the way of handling them. This struct will define the following behavior per group: - get_num_stats() - return the number of counters in the group. - fill_strings() - fill counters strings within the group. - fill_stats() - fill counters values within the group. All other patches will be straight forward refactoring per stats group, where Kamal will move each mlx5e stats group to use the new API. The idea is to have better flexibility and modularity to add new counters, all ethtool logic was rendered generic and loops through the generic stats groups and calls the groups callbacks to figure out how and what to report back to user space. Introducing new file en_stats.c to hold all the new stat groups logic and implementation. Static structures (counters descriptors) moved from en_stats.h to en_stats.c which reduces the mlx5_core binary footprint, originally reported and addressed by Stephen Hemminger: ("mlx5: fix space waste from ethtool descriptions") which was waived due to this re-design. ==================== Signed-off-by: David S.

Currently the mlx5e driver has multiple groups of stats, each group is used for different purposes and it may depend on hardware capabilities or not. The problem with the current implementation is that there is no clear API to create a new group of stats. This change define a new API to create a group of stats and simplifies the way of handling them by defining a new struct "mlx5e_stats_grp" which have the following three function pointers: - get_num_stats() - return the number of counters in the group. - fill_strings() - fill counters strings within the group. - fill_stats() - fill counters values within the group. The above function pointers are used within the ethtool callbaks while calling "ethtool -S" from userspace. This change also switch the SW group to use the new API.

The patch implements functions and admin queue commands needed to support cloud filters in the driver and adds cloud filters to configure these tc-flower filters. The classification function of the filter is to direct matched packets to a traffic class. The hardware traffic class is set based on the the classid reserved in the range :ffe0 - :ffef. Match Dst MAC and route to TC0: prio 1 flower dst_mac 3c:fd:fe:a0:d6:70 skip_sw\ hw_tc 1 Match Dst IPv4,Dst Port and route to TC1: prio 2 flower dst_ip 192.168.3.5/32\ ip_proto udp dst_port 25 skip_sw\ hw_tc 2 Match Dst IPv6,Dst Port and route to TC1: prio 3 flower dst_ip fe8::200:1\ ip_proto udp dst_port 66 skip_sw\ hw_tc 2 Delete tc flower filter: Example: Flow Director Sideband is disabled while configuring cloud filters via tc-flower and until any cloud filter exists. Unsupported matches when cloud filters are added using enhanced big buffer cloud filter mode of underlying switch include: 1. source port and source IP 2. Combined MAC address and IP fields. 3. Not specifying L4 port These filter matches can however be used to redirect traffic to the main VSI (tc 0) which does not require the enhanced big buffer cloud filter support.
