In order to access cached/paged memory, there are a couple of firmware commands (one for UMAC and one for LMAC) that let the host access memory and registers indirectly. Since this is done by the firmware on behalf of the host, even if memory is paged out or cached, the host will retrieve the memory as the firmware sees it (paged out memory will get paged in). Export this mechanism via a debugfs entry for both read and write access. WARNING: This mechanism has no protections at all. Invalid addresses may crash or hang the firmware. Writing to arbitrary memory also comes with no guarantees. Signed-off-by:

There's no need for the common MAC context function to have an if on AP mode, the values can be overridden in the AP-specific function later. Clean that up by adding the full command as a new parameter to the AP-specific function, and doing it there. Signed-off-by:

There was recently a Full AP mode feature added where hostap adds the station at auth stage, and not assoc. However, when running with legacy hostapd, we get the auth response before station was added, and tx_skb_non_sta fails to allocate a queue, resulting in a complete failure of association. Take care of this situation as well. Add a warning when no valid queue is returned at all and make mvm drop the packet instead of passing it on. Refactor the function a bit while at it.

In 9000 family products we added an option to let the OEM fuse the mac address via registers. If these registers are zeroed we use the OTP address instead. Make sure that the address provided by the OEM is valid and, if not, fall back to the OTP address as well.

If adapter is null the error exit path in mwifiex_shutdown_sw is to down the semaphore sem and print some debug via mwifiex_dbg. However, passing a NULL adapter to mwifiex_dbg causes a null pointer deference when accessing adapter->dev. This fix checks for a null adapter at the start of the function and to exit without the need to up the semaphore and we also skip the debug to avoid the null pointer dereference. Signed-off-by:

smatch reports: sta_cmdresp.c:1053 mwifiex_create_custom_regdomain() warn: possible memory leak of 'regd' Indeed, mwifiex_create_custom_regdomain() returns NULL in the case that channel is missing in the TLV without freeing regd. Moreover, some other error paths in this function return ERR_PTR values which are assigned without checking to the regd field in the mwifiex_adapter struct. The latter is only null-checked where used. Fix by freeing regd in the error path, and only update priv->adapter->regd if the returned pointer is valid.

Alexei Starovoitov says: ==================== ip_tunnel: add collect_md mode to IPv4/IPv6 tunnels Similar to geneve, vxlan, gre tunnels implement 'collect metadata' mode in ipip, ipip6, ip6ip6 tunnels. ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

the test creates 3 namespaces with veth connected via bridge. First two namespaces simulate two different hosts with the same IPv4 and IPv6 addresses configured on the tunnel interface and they communicate with outside world via standard tunnels. Third namespace creates collect_md tunnel that is driven by BPF program which selects different remote host (either first or second namespace) based on tcp dest port number while tcp dst ip is the same. This scenario is rough approximation of load balancer use case. The tests check both traditional tunnel configuration and collect_md mode. Signed-off-by:

Similar to gre, vxlan, geneve tunnels allow IPIP6 and IP6IP6 tunnels to operate in 'collect metadata' mode. Unlike ipv4 code here it's possible to reuse ip6_tnl_xmit() function for both collect_md and traditional tunnels. bpf_skb_[gs]et_tunnel_key() helpers and ovs (in the future) are the users.

Similar to gre, vxlan, geneve tunnels allow IPIP tunnels to operate in 'collect metadata' mode. bpf_skb_[gs]et_tunnel_key() helpers can make use of it right away. ovs can use it as well in the future (once appropriate ovs-vport abstractions and user apis are added). Note that just like in other tunnels we cannot cache the dst, since tunnel_info metadata can be different for every packet. Signed-off-by:

With large BDP TCP flows and lossy networks, it is very important to keep a low number of skbs in the write queue. RACK and SACK processing can perform a linear scan of it. We should avoid putting any payload in skb->head, so that SACK shifting can be done if needed. With this patch, we allow to pack ~0.5 MB per skb instead of the 64KB initially cooked at tcp_sendmsg() time. This gives a reduction of number of skbs in write queue by eight. tcp_rack_detect_loss() likes this. We still allow payload in skb->head for first skb put in the queue, to not impact RPC workloads.

Tariq Toukan says: ==================== mlx5e Order-0 pages for Striding RQ In this series, we refactor our Striding RQ receive-flow to always use fragmented WQEs (Work Queue Elements) using order-0 pages, omitting the flow that allocates and splits high-order pages which would fragment and deplete high-order pages in the system. The first patch gives a slight degradation, but opens the opportunity to using a simple page-cache mechanism of a fair size. The page-cache, implemented in patch 3, not only closes the performance gap but even gives a gain. In patch 2 we re-organize the code to better manage the calls for alloc/de-alloc pages in the RX flow.
