Donald Hunter says: ==================== tools: ynl: Add byte-order support for struct members This patchset adds support to ynl for handling byte-order in struct members. The first patch is a refactor to use predefined Struct() objects instead of generating byte-order specific formats on the fly. The second patch adds byte-order handling for struct members. ==================== Reviewed-by:

Use a dict of predefined Struct() objects to decode scalar types in native, big or little endian format. This removes the repetitive code for the scalar variants and ensures all the signed variants are supported. Signed-off-by:

When taking a network interface down (or removing a SFP module) after the PHY has encountered an error, phy_stop() complains incorrectly that it was called from HALTED state. The reason this is incorrect is that the network driver will have called phy_start() when the interface was brought up, and the fact that the PHY has a problem bears no relationship to the administrative state of the interface. Taking the interface administratively down (which calls phy_stop()) is always the right thing to do after a successful phy_start() call, whether or not the PHY has encountered an error.

Guillaume Nault says: ==================== ipv4: Remove RTO_ONLINK from udp, ping and raw sockets. udp_sendmsg(), ping_v4_sendmsg() and raw_sendmsg() use similar patterns for restricting their route lookup to on-link hosts. Although they use slightly different code, they all use RTO_ONLINK to override the least significant bit of their tos value. RTO_ONLINK is used to restrict the route scope even when the scope is set to RT_SCOPE_UNIVERSE. Therefore it isn't necessary: we can properly set the scope to RT_SCOPE_LINK instead. Removing RTO_ONLINK will allow to convert .flowi4_tos to dscp_t in the future, thus allowing to properly separate the DSCP from the ECN bits in the networking stack. This patch series defines a common helper to figure out what's the scope of the route lookup. This unifies the way udp, ping and raw sockets get their routing scope and removes their dependency on RTO_ONLINK. ==================== Signed-off-by: -

Use ip_sendmsg_scope() to properly initialise the scope in flowi4_init_output(), instead of overriding tos with the RTO_ONLINK flag. The objective is to eventually remove RTO_ONLINK, which will allow converting .flowi4_tos to dscp_t. Now that the scope is determined by ip_sendmsg_scope(), we need to check its result to set the 'connected' variable. Signed-off-by:

The objective is to eventually remove RTO_ONLINK, which will allow converting .flowi4_tos to dscp_t. The MSG_DONTROUTE and SOCK_LOCALROUTE cases were already handled by raw_sendmsg() (SOCK_LOCALROUTE was handled by the RT_CONN_FLAGS*() macros called by get_rtconn_flags()). However, opt.is_strictroute wasn't taken into account. Therefore, a side effect of this patch is to now honour opt.is_strictroute, and thus align raw_sendmsg() with ping_v4_sendmsg() and udp_sendmsg(). Since raw_sendmsg() was the only user of get_rtconn_flags(), we can now remove this function. Signed-off-by:

Add support for using IPv6 Big TCP on DQ which can handle large TSO/GRO packets. See https://lwn.net/Articles/895398/. This can improve the throughput and CPU usage. Perf test result: ip -d link show $DEV gso_max_size 185000 gso_max_segs 65535 tso_max_size 262143 tso_max_segs 65535 gro_max_size 185000 For performance, tested with neper using 9k MTU on hardware that supports 200Gb/s line rate. In single streams when line rate is not saturated, we expect throughput improvements. When the networking is performing at line rate, we expect cpu usage improvements.

David Howells says: ==================== splice, net: Replace sendpage with sendmsg(MSG_SPLICE_PAGES), part 1 Here's the first tranche of patches towards providing a MSG_SPLICE_PAGES internal sendmsg flag that is intended to replace the ->sendpage() op with calls to sendmsg(). MSG_SPLICE_PAGES is a hint that tells the protocol that it should splice the pages supplied if it can and copy them if not. This will allow splice to pass multiple pages in a single call and allow certain parts of higher protocols (e.g. sunrpc, iwarp) to pass an entire message in one go rather than having to send them piecemeal. This should also make it easier to handle the splicing of multipage folios. A helper, skb_splice_from_iter() is provided to do the work of splicing or copying data from an iterator. If a page is determined to be unspliceable (such as being in the slab), then the helper will give an error. Note that this facility is not made available to userspace and does not provide any sort of callback. This set consists of the following parts: (1) Define the MSG_SPLICE_PAGES flag and prevent sys_sendmsg() from being able to set it. (2) Add an extra argument to skb_append_pagefrags() so that something other than MAX_SKB_FRAGS can be used (sysctl_max_skb_frags for example). (3) Add the skb_splice_from_iter() helper to handle splicing pages into skbuffs for MSG_SPLICE_PAGES that can be shared by TCP, IP/UDP and AF_UNIX. (4) Implement MSG_SPLICE_PAGES support in TCP. (5) Make do_tcp_sendpages() just wrap sendmsg() and then fold it in to its various callers. (6) Implement MSG_SPLICE_PAGES support in IP and make udp_sendpage() just a wrapper around sendmsg(). (7) Implement MSG_SPLICE_PAGES support in IP6/UDP6. (8) Implement MSG_SPLICE_PAGES support in AF_UNIX. (9) Make AF_UNIX copy unspliceable pages.

Add layer 4 RSS hashing on UDP traffic to allow for the utilization of multiple queues for multiple connections on the same IP address. Previously, since the introduction of the driver, RSS hashing was only performed on the source and destination IP addresses of UDP packets thereby limiting UDP traffic to a single queue for multiple connections on the same IP address. The transport layer is now included in RSS hashing for UDP traffic, which was not previously the case. The reason behind the previous limitation is unclear - either a historic limitation of the NFP device, or an oversight. Signed-off-by:

We have been requiring the supported_interfaces bitmap to be filled in by MAC drivers that have a mac_select_pcs() method. Now that all MAC drivers fill in the supported_interfaces bitmap, it is time to enforce this. We have already required supported_interfaces to be set in order for optical SFPs to be configured in commit f81fa96d ("net: phylink: use phy_interface_t bitmaps for optical modules"). Refuse phylink creation if supported_interfaces is empty, and remove code to deal with cases where this mask is empty. Signed-off-by:

Add support for the Fiberstore SFP-10G-T and Walsun HXSX-ATRC-1 modules. Internally, the PCB silkscreen has what seems to be a part number of WT_502. Fiberstore use v2.2 whereas Walsun use v2.6. These modules contain a Marvell AQrate AQR113C PHY, accessible through I2C 0x51 using the "rollball" protocol. In both cases, the PHY is programmed to use 10GBASE-R with pause-mode rate adaption. Unlike the other rollball modules, these only need a four second delay before we can talk to the PHY. Signed-off-by:

Tony Nguyen says: ==================== ice: allow matching on meta data Michal Swiatkowski says: This patchset is intended to improve the usability of the switchdev slow path. Without matching on a meta data values slow path works based on VF's MAC addresses. It causes a problem when the VF wants to use more than one MAC address (e.g. when it is in trusted mode). Parse all meta data in the same place where protocol type fields are parsed. Add description for the currently implemented meta data. It is important to note that depending on DDP not all described meta data can be available. Using not available meta data leads to error returned by function which is looking for correct words in profiles read from DDP. There is also one small improvement, remove of rx field in rule info structure (patch 2). It is redundant. ==================== Signed-off-by: -
