In the RX buffer, the received data starts after a headroom used to align the IP header and to allow prepending headers efficiently. The prefetch() should take this into account, and prefetch from the very start of the received data. We can see that ether_addr_equal_64bits(), which is the first function to access the data, drops from the top of the perf top output. prefetch(data): Overhead Shared Object Symbol 11.64% [kernel] [k] eth_type_trans prefetch(data + MVPP2_MH_SIZE + MVPP2_SKB_HEADROOM): Overhead Shared Object Symbol 13.42% [kernel] [k] build_skb 10.35% [mvpp2] [k] mvpp2_rx 9.35% [kernel] [k] __netif_receive_skb_core 8.24% [kernel] [k] kmem_cache_free 7.97% [kernel] [k] dev_gro_receive 7.68% [kernel] [k] page_pool_put_page 7.32% [kernel] [k] kmem_cache_alloc 7.09% [mvpp2] [k] mvpp2_bm_pool_put 3.36% [kernel] [k] eth_type_trans Also, move the eth_type_trans() call a bit down, to give the RAM more time to prefetch the data.

The comparison of the u16 priv->phy_addr < 0 is always false because phy_addr is unsigned. Fix this by assigning the return from the call to function asix_read_phy_addr to int ret and using this for the less than zero error check comparison.

Pablo Neira Ayuso says: ==================== Netfilter updates for net-next The following patchset contains Netfilter updates for net-next: 1) Add nfgenmsg field to nfnetlink's struct nfnl_info and use it. 2) Remove nft_ctx_init_from_elemattr() and nft_ctx_init_from_setattr() helper functions. 3) Add the nf_ct_pernet() helper function to fetch the conntrack pernetns data area. 4) Expose TCP and UDP flowtable offload timeouts through sysctl, from Oz Shlomo. 5) Add nfnetlink_hook subsystem to fetch the netfilter hook pipeline configuration, from Florian Westphal. This also includes a new field to annotate the hook type as metadata. 6) Fix unsafe memory access to non-linear skbuff in the new SCTP chunk support for nft_exthdr, from Phil Sutter. ==================== Signed-off-by: -

In normal situations where the driver doesn't dereference "nsim_node->ddir" or "nsim_node->rate_parent" itself then we are not supposed to check the return from debugfs functions. In the case of debugfs_create_dir() the check was wrong as well because it doesn't return NULL, it returns error pointers. Signed-off-by:

The "hi" variable is a u64 but the qca8k_read() writes to the top 32 bits of it. That will work on little endian systems but it's a bit subtle. It's cleaner to make declare "hi" as a u32. We will still need to cast it when we shift it later on in the function but that's fine. Fixes: 7c9896e3 ("net: dsa: qca8k: check return value of read functions correctly") Signed-off-by:

Commit ca893194 ("net: dsa: b53: Keep CPU port as tagged in all VLANs") forced the CPU port to be always tagged in any VLAN membership. This was necessary back then because we did not support Broadcom tags for all configurations so the only way to differentiate tagged and untagged traffic while DSA_TAG_PROTO_NONE was used was to force the CPU port into being always tagged. With most configurations enabling Broadcom tags, especially after 8fab459e ("net: dsa: b53: Enable Broadcom tags for 531x5/539x families") we do not need to apply this unconditional force tagging of the CPU port in all VLANs. A helper function is introduced to faciliate the encapsulation of the specific condition requiring the CPU port to be tagged in all VLANs and the dsa_switch_ops::untag_bridge_pvid boolean is moved to when dsa_switch_ops::setup is called when we have already determined the tagging protocol we will be using.

While iterating through an SCTP packet's chunks, skb_header_pointer() is called for the minimum expected chunk header size. If (that part of) the skbuff is non-linear, the following memcpy() may read data past temporary buffer '_sch'. Use skb_copy_bits() instead which does the right thing in this situation.

We are currently assuming that GMAC_AHB_RESET will already be deasserted by the bootloader. However if this has not been done, probing of the GMAC will fail. To remedy this we must ensure GMAC_AHB_RESET has been deasserted prior to probing. v2 changes: - remove NULL condition check for stmmac_ahb_rst in stmmac_main.c - unwrap dev_err() message in stmmac_main.c - add PTR_ERR() around plat->stmmac_ahb_rst in stmmac_platform.c v3 changes: - add error pointer to dev_err() output - add reset_control_assert(stmmac_ahb_rst) in stmmac_dvr_remove - revert PTR_ERR() around plat->stmmac_ahb_rst since this is performed on the returned value of ret by the calling function Signed-off-by:
