Tom Lendacky says: ==================== amd-xgbe: AMD XGBE driver updates 2016-11-14 This patch series addresses some minor issues found in the recently accepted patch series for the AMD XGBE driver. The following fixes are included in this driver update series: - Fix how a mask is applied to a Clause 37 register value - Fix some coccinelle identified warnings This patch series is based on net-next. ==================== Signed-off-by: -
Lendacky, Thomas authored
Fix up some warnings that were identified by coccinelle: Clean up an if/else block that can look confusing since the same statement is executed in an "else if" check and the final "else" statement. Change a variable from unsigned int to int since it is used in an if statement checking the value to be less than 0. Reported-by:

Michael Weiser says: ==================== sun4i-emac: Fixes for running a big-endian kernel on Cubieboard2 the following patches are what remains to be fixed in order to allow running a big-endian kernel on the Cubieboard2. The first patch fixes up endianness problems with DMA descriptors in the stmmac driver preventing it from working correctly when runnning a big-endian kernel. The second patch adds the ability to enable diagnostic messages in the sun4i-emac driver which were instrumental in finding the problem fixed by patch number three: Endianness confusion caused by dual-purpose I/O register usage in sun4i-emac. All of these have been tested successfully on a Cubieboard2 DualCard. Changes since v4: - Rebased to current master - Removed already applied patches to sunxi-mmc and sunxi-Kconfig Changes since v3: - Rebased sunxi-mmc patch against Ulf's mmc.git/next - Changed Kconfig change to enable big-endian support only for sun7i devices Changes since v2: - Fixed typo in stmmac patch causing a build failure - Added sun4i-emac patches Changes since v1: - Fixed checkpatch niggles - Added respective Cc:s ==================== Signed-off-by: -

The EMAC EMAC_RX_IO_DATA_REG data register is dual-purpose: On one hand it is used to move actual packet data off the wire. This will be in wire-format and accepted as such by higher layers such as IP. Therefore it is correctly read as-is (i.e. raw) using readsl. On the other hand it provides metadata about incoming transfers to the driver such as length and checksum validation status. This data is little-endian, always and it is interpreted by the driver. Therefore it needs to be swapped to CPU endianness to make sense to the driver. This is already done for the "receive header" but not rxhdr. Read rxhdr using readl in order for sun4i-emac to work correctly when running a big-endian kernel. Signed-off-by:

sun4i-emac has the ability to print a number of diagnostic messages using dev_dbg depending on message level settings implemented using netif_msg_* macros. But there's no way to actually enable them. Add the ability to switch diagnostic messages on using either a module parameter debug or ethtool -s <netif> msglvl <flags>. Signed-off-by:

The stmmac driver does not take into account the processor may be big endian when writing the DMA descriptors. This causes the ethernet interface not to be initialised correctly when running a big-endian kernel. Change the descriptors for DMA to use __le32 and ensure they are suitably swapped before writing. Tested successfully on the Cubieboard2. Signed-off-by:

Florian Fainelli says: ==================== net: phy: Centralize auto-negotation restart This patch series centralizes how ethtool::nway_reset is implemented by providing a PHYLIB function which calls into genphy_restart_aneg(). All drivers below are converted to use this new helper function. Some other have specific requirements that make them not quite suitable for a straight forward conversion. There is another patch series which implements ethtool::nway_reset using the helper function introduced that depends on this patch series. ==================== Signed-off-by: -

Move route sanity check to respective vxlan[4/6]_get_route functions. This allows us to perform all sanity checks before caching the dst so that we can avoid these checks on subsequent packets. This give move accurate metadata information for packet from fill_metadata_dst(). Signed-off-by:

vxlan egress path error handling has became complicated, it need to handle IPv4 and IPv6 tunnel cases. Earlier patch removes vlan handling from vxlan_build_skb(), so vxlan_build_skb does not need to free skb and we can simplify the xmit path by having single error handling for both type of tunnels.

The commit 850cbadd ("udp: use it's own memory accounting schema") assumes that the socket proto has memory accounting enabled, but this is not the case for UDPLITE. Fix it enabling memory accounting for UDPLITE and performing fwd allocated memory reclaiming on socket shutdown. UDP and UDPLITE share now the same memory accounting limits. Also drop the backlog receive operation, since is no more needed. Fixes: 850cbadd ("udp: use it's own memory accounting schema") Reported-by:

Martin KaFai Lau says: ==================== bpf: LRU map This patch set adds LRU map implementation to the existing BPF map family. The first few patches introduce the basic BPF LRU list implementation. The later patches introduce the LRU versions of the existing BPF_MAP_TYPE_LRU_[PERCPU_]HASH maps by leveraging the BPF LRU list. v2: - Added a percpu LRU list option which can be specified as a map attribute. [Note: percpu LRU list has nothing to do with the map's value] - Removed the cpu variable from the struct bpf_lru_locallist since it is not needed. - Changed the __bpf_lru_node_move_out to __bpf_lru_node_move_to_free in patch 1 to prepare the percpu LRU list in patch 2. - Moved the test_lru_map under selftests - Refactored a few things in the test codes ==================== Signed-off-by: -

This patch has some unit tests and a test_lru_dist. The test_lru_dist reads in the numeric keys from a file. The files used here are generated by a modified fio-genzipf tool originated from the fio test suit. The sample data file can be found here: https://github.com/iamkafai/bpf-lru The zipf.* data files have 100k numeric keys and the key is also ranged from 1 to 100k. The test_lru_dist outputs the number of unique keys (nr_unique). F.e. The following means, 61239 of them is unique out of 100k keys. nr_misses means it cannot be found in the LRU map, so nr_misses must be >= nr_unique. test_lru_dist also simulates a perfect LRU map as a comparison: [root@arch-fb-vm1 ~]# ~/devshare/fb-kernel/linux/samples/bpf/test_lru_dist \ /root/zipf.100k.a1_01.out 4000 1 ... test_parallel_lru_dist (map_type:9 map_flags:0x0): task:0 BPF LRU: nr_unique:23093(/100000) nr_misses:31603(/100000) task:0 Perfect LRU: nr_unique:23093(/100000 nr_misses:34328(/100000) .... test_parallel_lru_dist (map_type:9 map_flags:0x2): task:0 BPF LRU: nr_unique:23093(/100000) nr_misses:31710(/100000) task:0 Perfect LRU: nr_unique:23093(/100000 nr_misses:34328(/100000) [root@arch-fb-vm1 ~]# ~/devshare/fb-kernel/linux/samples/bpf/test_lru_dist \ /root/zipf.100k.a0_01.out 40000 1 ... test_parallel_lru_dist (map_type:9 map_flags:0x0): task:0 BPF LRU: nr_unique:61239(/100000) nr_misses:67054(/100000) task:0 Perfect LRU: nr_unique:61239(/100000 nr_misses:66993(/100000) ... test_parallel_lru_dist (map_type:9 map_flags:0x2): task:0 BPF LRU: nr_unique:61239(/100000) nr_misses:67068(/100000) task:0 Perfect LRU: nr_unique:61239(/100000 nr_misses:66993(/100000) LRU map has also been added to map_perf_test: /* Global LRU */ [root@kerneltest003.31.prn1 ~]# for i in 1 4 8; do echo -n "$i cpus: "; \ ./map_perf_test 16 $i | awk '{r += $3}END{print r " updates"}'; done 1 cpus: 2934082 updates 4 cpus: 7391434 updates 8 cpus: 6500576 updates /* Percpu LRU */ [root@kerneltest003.31.prn1 ~]# for i in 1 4 8; do echo -n "$i cpus: "; \ ./map_perf_test 32 $i | awk '{r += $3}END{print r " updates"}'; done 1 cpus: 2896553 updates 4 cpus: 9766395 updates 8 cpus: 17460553 updates Signed-off-by:
