This helper serves to know if two switchdev port netdevices belong to the same HW ASIC, e.g to figure out if forwarding offload is possible between them. Signed-off-by:

Towards reusing the TC offloads code for an SRIOV use-case, change some of the helper functions to have _nic in their names so it's clear what's NIC unique and what's general. Also group together the NIC related helpers so we can easily branch per the use-case in downstream patch. Signed-off-by:

This allows for upper levels in the driver, e.g the TC offload code to add e-switch offloaded steering rules. The caller provides the rule spec for matching, action, source and destination vports. Signed-off-by:

Or Gerlitz authored
In the offloads mode, some slow path rules are added by the driver (e.g send-to-vport), while offloaded rules are to be added from upper layers. The slow path rules have lower priority and we don't want matching on offloaded rules to suffer from extra steering hops related to the slow path rules. We use two priorities, one for offloaded rules (fast path), and one for the control rules (slow path). To allow for that, we enable two priorities for the FDB namespace in the FS core code.

This commit utilize the ability of ConnectX-4 to bulk read flow counters. Few bulk counter queries could be done instead of issuing thousands of firmware commands per second to get statistics of all flows set to HW, such as those programmed when we offload tc filters. Counters are stored sorted by hardware id, and queried in blocks (id + number of counters). Due to hardware requirement, start of block and number of counters in a block must be four aligned.

First two patches are preparing the grounds for the 3rd patch. After the 3rd, they are not strictly logically related to the patchset, but I kept them together as they depend on each other.

Currently only read-only checks are performed up to the point on where we check if peer is ECN capable, checks which we can avoid otherwise. The flag ecn_ce_done is only used to perform this check once per incoming packet, and nothing more. Thus this patch moves the peer check up. Signed-off-by:

We should not clear that flag when switching to a new skb from a GSO skb because it would cause ECN processing to happen multiple times per GSO skb, which is not wanted. Instead, let it be processed once per chunk. That is, in other words, once per IP header available. Fixes: 90017acc ("sctp: Add GSO support") Signed-off-by:

Identifying address family operations during rx path is not something expensive but it's ugly to the eye to have it done multiple times, specially when we already validated it during initial rx processing. This patch takes advantage of the now shared sctp_input_cb and make the pointer to the operations readily available. Signed-off-by:

SCTP will try to access original IP headers on sctp_recvmsg in order to copy the addresses used. There are also other places that do similar access to IP or even SCTP headers. But after 90017acc ("sctp: Add GSO support") they aren't always there because they are only present in the header skb. SCTP handles the queueing of incoming data by cloning the incoming skb and limiting to only the relevant payload. This clone has its cb updated to something different and it's then queued on socket rx queue. Thus we need to fix this in two moments. For rx path, not related to socket queue yet, this patch uses a partially copied sctp_input_cb to such GSO frags. This restores the ability to access the headers for this part of the code. Regarding the socket rx queue, it removes iif member from sctp_event and also add a chunk pointer on it. With these changes we're always able to reach the headers again. The biggest change here is that now the sctp_chunk struct and the original skb are only freed after the application consumed the buffer. Note however that the original payload was already like this due to the skb cloning. For iif, SCTP's IPv4 code doesn't use it, so no change is necessary. IPv6 now can fetch it directly from original's IPv6 CB as the original skb is still accessible. In the future we probably can simplify sctp_v*_skb_iif() stuff, as sctp_v4_skb_iif() was called but it's return value not used, and now it's not even called, but such cleanup is out of scope for this change.

The next patch needs 8 bytes in there. sctp_ulpevent has a hole due to bad alignment; msg_flags is using 4 bytes while it actually uses only 2, so we shrink it, and iif member (4 bytes) which can be easily fetched from another place once the next patch is there, so we remove it and thus creating space for 8 bytes.

We process input path in other files too and having access to it is nice, so move it to a header where it's shared. Signed-off-by:

This script helps to create bonding network devices based on synthetic NIC (the virtual network adapter usually provided by Hyper-V) and the matching VF NIC (SRIOV virtual function). So the synthetic NIC and VF NIC can function as one network device, and fail over to the synthetic NIC if VF is down. Mayjor distros (RHEL, Ubuntu, SLES) supported by Hyper-V are supported by this script. Signed-off-by:

The Makefile controlling compilation of this file is obj-y, meaning that it currently is never being built as a module. Since MODULE_ALIAS is a no-op for non-modular code, we can simply remove the MODULE_ALIAS_NETPROTO variant used here. We replace module.h with kmod.h since the file does make use of request_module() in order to load other modules from here. We don't have to worry about init.h coming in via the removed module.h since the file explicitly includes init.h already. Cc: "David S.
