* netfilter: nft_{fwd,dup}_netdev: add offload supportPablo Neira Ayuso2019-09-107-3/+70
| | | | | | | | | | | | | This patch adds support for packet mirroring and redirection. The nft_fwd_dup_netdev_offload() function configures the flow_action object for the fwd and the dup actions. Extend nft_flow_rule_destroy() to release the net_device object when the flow_rule object is released, since nft_fwd_dup_netdev_offload() bumps the net_device reference counter.

| * net/tls: remove the record tail optimizationJakub Kicinski2019-09-071-20/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For TLS device offload the tag/message authentication code are filled in by the device. The kernel merely reserves space for them. Because device overwrites it, the contents of the tag make do no matter. Current code tries to save space by reusing the header as the tag. This, however, leads to an additional frag being created and defeats buffer coalescing (which trickles all the way down to the drivers). Remove this optimization, and try to allocate the space for the tag in the usual way, leave the memory uninitialized. If memory allocation fails rewind the record pointer so that we use the already copied user data as tag. Note that the optimization was actually buggy, as the tag for TLS 1.2 is 16 bytes, but header is just 13, so the reuse may had looked past the end of the page..

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct mgmt_rp_get_connections { ... struct mgmt_addr_info addr[0]; } __packed; Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes. So, replace the following form: sizeof(*rp) + (i * sizeof(struct mgmt_addr_info)); with: struct_size(rp, addr, i) Also, notice that, in this case, variable rp_len is not necessary, hence it is removed.

Phil Karn reported[2] that on busy networks with lots of unresolved multicast routing entries, the creation of new multicast group routes can be extremely slow and unreliable. The reason is we hard-coded multicast route entries with unresolved source addresses(cache_resolve_queue_len) to 10. If some multicast route never resolves and the unresolved source addresses increased, there will be no ability to create new multicast route cache. To resolve this issue, we need either add a sysctl entry to make the cache_resolve_queue_len configurable, or just remove cache_resolve_queue_len limit directly, as we already have the socket receive queue limits of mrouted socket, pointed by David. >From my side, I'd perfer to remove the cache_resolve_queue_len limit instead of creating two more(IPv4 and IPv6 version) sysctl entry. [1] https://lkml.org/lkml/2018/7/22/11 [2] https://lkml.org/lkml/2018/7/21/343 v3: instead of remove cache_resolve_queue_len totally, let's only remove the hard code limit when allocate the unresolved cache, as Eric Dumazet suggested, so we don't need to re-count it in other places. v2: hold the mfc_unres_lock while walking the unresolved list in queue_count(), as Nikolay Aleksandrov remind.

| * | hv_netvsc: Sync offloading features to VF NICHaiyang Zhang2019-09-071-2/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | VF NIC may go down then come up during host servicing events. This causes the VF NIC offloading feature settings to roll back to the defaults. This patch can synchronize features from synthetic NIC to the VF NIC during ndo_set_features (ethtool -K), and netvsc_register_vf when VF comes back after host events.

| * | hv_netvsc: Allow scatter-gather feature to be tunableHaiyang Zhang2019-09-073-3/+4
|/ / | | | | | | | | | | | | | | | | | | In a previous patch, the NETIF_F_SG was missing after the code changes. That caused the SG feature to be "fixed". This patch includes it into hw_features, so it is tunable again.
