In preparation for supporting SGMII, let's make the code a bit more generic. Add a new callback for MAC configuration so that we can assign a different variant of it in the future. Signed-off-by:

On sa8775p, the EMAC revision is 4 and we use SGMII instead of RGMII. There's no "rgmii" clock but there's a fourth clock under a different name: "phyaux". Add a new field to the chip data struct that specifies the link clock name. Default to "rgmii" for backward compatibility. Signed-off-by:

The err_mem label's name is unclear. It actually should be reached on any error after stmmac_probe_config_dt() succeeds. Name it after the cleanup action that needs to be called before exiting. Signed-off-by:

We can use a devm action to completely drop the remove callback and use stmmac_pltfr_remove() directly for remove. We can also drop one of the goto labels. Signed-off-by:

The text has been cut/paste from genphy_c45_ethtool_get_eee but not changed to reflect it performs set. Additionally, extend the comment. This function implements the logic that eee_enabled has global control over EEE. When eee_enabled is false, no link modes will be advertised, and as a result, the MAC should not transmit LPI.

Blamed commit added these helpers for sake of detecting RAW sockets specific ioctl. syzbot complained about it [1]. Issue here is that RAW sockets could pretend there was no need to call ipmr_sk_ioctl() Regardless of inet_sk(sk)->inet_num, we must be prepared for ipmr_ioctl() being called later. This must happen from ipmr_sk_ioctl() context only. We could add a safety check in ipmr_ioctl() at the risk of breaking applications. Instead, remove sk_is_ipmr() and sk_is_icmpv6() because their name would be misleading, once we change their implementation.

If an AF_ALG socket bound to a hashing algorithm is sent a zero-length message with MSG_MORE set and then recvmsg() is called without first sending another message without MSG_MORE set to end the operation, an oops will occur because the crypto context and result doesn't now get set up in advance because hash_sendmsg() now defers that as long as possible in the hope that it can use crypto_ahash_digest() - and then because the message is zero-length, it the data wrangling loop is skipped. Fix this by handling zero-length sends at the top of the hash_sendmsg() function. If we're not continuing the previous sendmsg(), then just ignore the send (hash_recvmsg() will invent something when called); if we are continuing, then we finalise the request at this point if MSG_MORE is not set to get any error here, otherwise the send is of no effect and can be ignored. Whilst we're at it, remove the code to create a kvmalloc'd scatterlist if we get more than ALG_MAX_PAGES - this shouldn't happen.

The new phy driver attempts to select a driver from another subsystem, but that fails when the NVMEM subsystem is disabled: WARNING: unmet direct dependencies detected for NVMEM_MTK_EFUSE Depends on [n]: NVMEM [=n] && (ARCH_MEDIATEK [=n] || COMPILE_TEST [=y]) && HAS_IOMEM [=y] Selected by [y]: - MEDIATEK_GE_SOC_PHY [=y] && NETDEVICES [=y] && PHYLIB [=y] && (ARM64 && ARCH_MEDIATEK [=n] || COMPILE_TEST [=y]) I could not see an actual compile time dependency, so presumably this is only needed for for working correctly but not technically a dependency on that particular nvmem driver implementation, so it would likely be safe to remove the select for compile testing. To keep the spirit of the original 'select', just replace this with a 'depends on' that ensures that the driver will work but does not get in the way of build testing.

Changes: v2->v1: * Removes arbitrary rule that the PHC servo must restore the frequency to the value used in the last .adjfine call if any other PHC operation is used after a .adjphase operation. * Removes a macro introduced in v1 for adding PTP sysfs device attribute nodes using a callback for populating the data.

ipv6_rpl_srh_rcv() checks if ipv6_hdr(skb)->daddr or ohdr->rpl_segaddr[i] is the multicast address with ipv6_addr_type(). We have the same check for ipv6_hdr(skb)->daddr in ipv6_rthdr_rcv(), so we need not recheck it in ipv6_rpl_srh_rcv(). Also, we should use ipv6_addr_is_multicast() for ohdr->rpl_segaddr[i] instead of ipv6_addr_type(). Signed-off-by:

As Eric Dumazet pointed out [0], ipv6_rthdr_rcv() pulls these data - Segment Routing Header : 8 - Hdr Ext Len : skb_transport_header(skb)[1] << 3 needed by ipv6_rpl_srh_rcv(). We can remove pskb_may_pull() and replace pskb_pull() with skb_pull() in ipv6_rpl_srh_rcv().

mlx5-updates-2023-06-16 1) Added a new event handler to firmware sync reset, which is used to support firmware sync reset flow on smart NIC. Adding this new stage to the flow enables the firmware to ensure host PFs unload before ECPFs unload, to avoid race of PFs recovery. 2) Debugfs for mlx5 eswitch bridge offloads 3) Added two new counters for vport stats 4) Minor Fixups and cleanups for net-next branch Signed-off-by:
