Since commit 99724c18 ("mlxsw: spectrum: Introduce support for router interfaces") we no longer rely on flooding traffic to the CPU in order to trap packets intended for the host itself. Therefore, the FDB MC trap can be removed. Remove traps for protocols that are not supported yet.

Typical NAPI drivers use napi_consume_skb(skb) at TX completion time. This put skb in a percpu special queue, napi_alloc_cache, to get bulk frees. It turns out the queue is not flushed and hits the NAPI_SKB_CACHE_SIZE limit quite often, with skbs that were queued hundreds of usec earlier. I measured this can take ~6000 nsec to perform one flush. __kfree_skb_flush() can be called from two points right now : 1) From net_tx_action(), but only for skbs that were queued to sd->completion_queue. -> Irrelevant for NAPI drivers in normal operation. 2) From net_rx_action(), but only under high stress or if RPS/RFS has a pending action. This patch changes net_rx_action() to perform the flush in all cases and after more urgent operations happened (like kicking remote CPUS for RPS/RFS).

Daniel Mack says: ==================== Add eBPF hooks for cgroups This is v9 of the patch set to allow eBPF programs for network filtering and accounting to be attached to cgroups, so that they apply to all sockets of all tasks placed in that cgroup. The logic also allows to be extendeded for other cgroup based eBPF logic. Again, only minor details are updated in this version. Changes from v8: * Move the egress hooks into ip_finish_output() and ip6_finish_output() so they run after the netfilter hooks. For IPv4 multicast, add a new ip_mc_finish_output() callback that is invoked on success by netfilter, and call the eBPF program from there. Changes from v7: * Replace the static inline function cgroup_bpf_run_filter() with two specific macros for ingress and egress. This addresses David Miller's concern regarding skb->sk vs. sk in the egress path. Thanks a lot to Daniel Borkmann and Alexei Starovoitov for the suggestions. Changes from v6: * Rebased to 4.9-rc2 * Add EXPORT_SYMBOL(__cgroup_bpf_run_filter). The kbuild test robot now succeeds in building this version of the patch set. * Switch from bpf_prog_run_save_cb() to bpf_prog_run_clear_cb() to not tamper with the contents of skb->cb[]. Pointed out by Daniel Borkmann. * Use sk_to_full_sk() in the egress path, as suggested by Daniel Borkmann. * Renamed BPF_PROG_TYPE_CGROUP_SOCKET to BPF_PROG_TYPE_CGROUP_SKB, as requested by David Ahern. * Added Alexei's Acked-by tags. Changes from v5: * The eBPF programs now operate on L3 rather than on L2 of the packets, and the egress hooks were moved from __dev_queue_xmit() to ip*_output(). * For BPF_PROG_TYPE_CGROUP_SOCKET, disallow direct access to the skb through BPF_LD_[ABS|IND] instructions, but hook up the bpf_skb_load_bytes() access helper instead. Thanks to Daniel Borkmann for the help. Changes from v4: * Plug an skb leak when dropping packets due to eBPF verdicts in __dev_queue_xmit(). Spotted by Daniel Borkmann. * Check for sk_fullsock(sk) in __cgroup_bpf_run_filter() so we don't operate on timewait or request sockets. Suggested by Daniel Borkmann. * Add missing @parent parameter in kerneldoc of __cgroup_bpf_update(). Spotted by Rami Rosen. * Include linux/jump_label.h from bpf-cgroup.h to fix a kbuild error. Changes from v3: * Dropped the _FILTER suffix from BPF_PROG_TYPE_CGROUP_SOCKET_FILTER, renamed BPF_ATTACH_TYPE_CGROUP_INET_{E,IN}GRESS to BPF_CGROUP_INET_{IN,E}GRESS and alias BPF_MAX_ATTACH_TYPE to __BPF_MAX_ATTACH_TYPE, as suggested by Daniel Borkmann. * Dropped the attach_flags member from the anonymous struct for BPF attach operations in union bpf_attr. They can be added later on via CHECK_ATTR. Requested by Daniel Borkmann and Alexei. * Release old_prog at the end of __cgroup_bpf_update rather that at the beginning to fix a race gap between program updates and their users. Spotted by Daniel Borkmann. * Plugged an skb leak when dropping packets on the egress path. Spotted by Daniel Borkmann. * Add cgroups@vger.kernel.org to the loop, as suggested by Rami Rosen. * Some minor coding style adoptions not worth mentioning in particular. Changes from v2: * Fixed the RCU locking details Tejun pointed out. * Assert bpf_attr.flags == 0 in BPF_PROG_DETACH syscall handler. Changes from v1: * Moved all bpf specific cgroup code into its own file, and stub out related functions for !CONFIG_CGROUP_BPF as static inline nops. This way, the call sites are not cluttered with #ifdef guards while the feature remains compile-time configurable. * Implemented the new scheme proposed by Tejun. Per cgroup, store one set of pointers that are pinned to the cgroup, and one for the programs that are effective. When a program is attached or detached, the change is propagated to all the cgroup's descendants. If a subcgroup has its own pinned program, skip the whole subbranch in order to allow delegation models. * The hookup for egress packets is now done from __dev_queue_xmit(). * A static key is now used in both the ingress and egress fast paths to keep performance penalties close to zero if the feature is not in use. * Overall cleanup to make the accessors use the program arrays. This should make it much easier to add new program types, which will then automatically follow the pinned vs. effective logic. * Fixed locking issues, as pointed out by Eric Dumazet and Alexei Starovoitov. Changes to the program array are now done with xchg() and are protected by cgroup_mutex. * eBPF programs are now expected to return 1 to let the packet pass, not >= 0. Pointed out by Alexei. * Operation is now limited to INET sockets, so local AF_UNIX sockets are not affected. The enum members are renamed accordingly. In case other socket families should be supported, this can be extended in the future. * The sample program learned to support both ingress and egress, and can now optionally make the eBPF program drop packets by making it return 0. ==================== Signed-off-by: NDavid S.

Add a simple userpace program to demonstrate the new API to attach eBPF programs to cgroups. This is what it does: * Create arraymap in kernel with 4 byte keys and 8 byte values * Load eBPF program The eBPF program accesses the map passed in to store two pieces of information. The number of invocations of the program, which maps to the number of packets received, is stored to key 0. Key 1 is incremented on each iteration by the number of bytes stored in the skb. * Detach any eBPF program previously attached to the cgroup * Attach the new program to the cgroup using BPF_PROG_ATTACH * Once a second, read map[0] and map[1] to see how many bytes and packets were seen on any socket of tasks in the given cgroup. The program takes a cgroup path as 1st argument, and either "ingress" or "egress" as 2nd. Optionally, "drop" can be passed as 3rd argument, which will make the generated eBPF program return 0 instead of 1, so the kernel will drop the packet. libbpf gained two new wrappers for the new syscall commands.

If the cgroup associated with the receiving socket has an eBPF programs installed, run them from ip_output(), ip6_output() and ip_mc_output(). From mentioned functions we have two socket contexts as per 7026b1dd ("netfilter: Pass socket pointer down through okfn()."). We explicitly need to use sk instead of skb->sk here, since otherwise the same program would run multiple times on egress when encap devices are involved, which is not desired in our case. eBPF programs used in this context are expected to either return 1 to let the packet pass, or != 1 to drop them. The programs have access to the skb through bpf_skb_load_bytes(), and the payload starts at the network headers (L3). Note that cgroup_bpf_run_filter() is stubbed out as static inline nop for !CONFIG_CGROUP_BPF, and is otherwise guarded by a static key if the feature is unused.

Extend the bpf(2) syscall by two new commands, BPF_PROG_ATTACH and BPF_PROG_DETACH which allow attaching and detaching eBPF programs to a target. On the API level, the target could be anything that has an fd in userspace, hence the name of the field in union bpf_attr is called 'target_fd'. When called with BPF_ATTACH_TYPE_CGROUP_INET_{E,IN}GRESS, the target is expected to be a valid file descriptor of a cgroup v2 directory which has the bpf controller enabled. These are the only use-cases implemented by this patch at this point, but more can be added. If a program of the given type already exists in the given cgroup, the program is swapped automically, so userspace does not have to drop an existing program first before installing a new one, which would otherwise leave a gap in which no program is attached. For more information on the propagation logic to subcgroups, please refer to the bpf cgroup controller implementation. The API is guarded by CAP_NET_ADMIN.

This patch adds two sets of eBPF program pointers to struct cgroup. One for such that are directly pinned to a cgroup, and one for such that are effective for it. To illustrate the logic behind that, assume the following example cgroup hierarchy. A - B - C \ D - E If only B has a program attached, it will be effective for B, C, D and E. If D then attaches a program itself, that will be effective for both D and E, and the program in B will only affect B and C. Only one program of a given type is effective for a cgroup. Attaching and detaching programs will be done through the bpf(2) syscall. For now, ingress and egress inet socket filtering are the only supported use-cases.

Florian Fainelli says: ==================== net: phy: broadcom: Wirespeed/downshift support This patch series adds support for the Broadcom Wirespeed, aka downsfhit feature utilizing the recently added ethtool PHY tunables. Tested with two Gigabit link partners with a 4-wire cable having only 2 pairs connected. Last patch in the series is a fix that was required for testing, which should make it to -stable, which I can submit separate against net if you prefer David. ==================== Signed-off-by: NDavid S.

In case the link change and EEE is enabled or disabled, always try to re-negotiate this with the link partner. Fixes: 450b05c1 ("net: dsa: bcm_sf2: add support for controlling EEE") Signed-off-by: NFlorian Fainelli <f.fainelli@gmail.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Add support for configuring the downshift/Wirespeed enable/disable toggles and specify a link retry value ranging from 1 to 9. Since the integrated BCM7xxx have issues when wirespeed is enabled and EEE is also enabled, we do disable EEE if wirespeed is enabled.

In preparation for adding support for Wirespeed/downshift, we need to change bcm_phy_eee_enable() to allow enabling or disabling EEE, so make the function take an extra enable/disable boolean parameter and rename it to illustrate it sets EEE, not necessarily just enables it.

Broadcom's Wirespeed feature allows us to configure how auto-negotiation should behave with fewer working pairs of wires on a cable. Add support code for retrieving and setting such downshift counters using the recently added ethtool downshift tunables.

In commit 2331ccc5 ("tcp: enhance tcp collapsing"), we made a first step allowing copying right skb to left skb head. Since all skbs in socket write queue are headless (but possibly the very first one), this strategy often does not work. This patch extends tcp_collapse_retrans() to perform frag shifting, thanks to skb_shift() helper. This helper needs to not BUG on non headless skbs, as callers are ok with that. Tested: Following packetdrill test now passes : 0.000 socket(..., SOCK_STREAM, IPPROTO_TCP) = 3 +0 setsockopt(3, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0 +0 bind(3, ..., ...) = 0 +0 listen(3, 1) = 0 +0 < S 0:0(0) win 32792 <mss 1460,sackOK,nop,nop,nop,wscale 8> +0 > S. 0:0(0) ack 1 <mss 1460,nop,nop,sackOK,nop,wscale 8> +.100 < . 1:1(0) ack 1 win 257 +0 accept(3, ..., ...) = 4 +0 setsockopt(4, SOL_TCP, TCP_NODELAY, [1], 4) = 0 +0 write(4, ..., 200) = 200 +0 > P. 1:201(200) ack 1 +.001 write(4, ..., 200) = 200 +0 > P. 201:401(200) ack 1 +.001 write(4, ..., 200) = 200 +0 > P. 401:601(200) ack 1 +.001 write(4, ..., 200) = 200 +0 > P. 601:801(200) ack 1 +.001 write(4, ..., 200) = 200 +0 > P. 801:1001(200) ack 1 +.001 write(4, ..., 100) = 100 +0 > P. 1001:1101(100) ack 1 +.001 write(4, ..., 100) = 100 +0 > P. 1101:1201(100) ack 1 +.001 write(4, ..., 100) = 100 +0 > P. 1201:1301(100) ack 1 +.001 write(4, ..., 100) = 100 +0 > P. 1301:1401(100) ack 1 +.099 < . 1:1(0) ack 201 win 257 +.001 < . 1:1(0) ack 201 win 257 <nop,nop,sack 1001:1401> +0 > P. 201:1001(800) ack 1 Signed-off-by: NEric Dumazet <edumazet@google.com> Cc: Neal Cardwell <ncardwell@google.com> Cc: Yuchung Cheng <ycheng@google.com> Acked-by: NYuchung Cheng <ycheng@google.com> Signed-off-by: NDavid S.

The VMware VMCI transport supports loopback inside virtual machines. This patch implements loopback for virtio-vsock. Flow control is handled by the virtio-vsock protocol as usual. The sending process stops transmitting on a connection when the peer's receive buffer space is exhausted. Cathy Avery <cavery@redhat.com> noticed this difference between VMCI and virtio-vsock when a test case using loopback failed. Although loopback isn't the main point of AF_VSOCK, it is useful for testing and virtio-vsock must match VMCI semantics so that userspace programs run regardless of the underlying transport. My understanding is that loopback is not supported on the host side with VMCI. Follow that by implementing it only in the guest driver, not the vhost host driver.
