Ido Schimmel says: ==================== nexthop: Support large scale nexthop flushing Patch #1 fixes a day-one bug in the nexthop code and allows "ip nexthop flush" to work correctly with large number of nexthops that do not fit in a single-part dump. Patch #2 adds a test case. Targeting at net-next since this use case never worked, the flow is pretty obscure and such a large number of nexthops is unlikely to be used in any real-world scenario.

Currently, a multi-part nexthop dump is restarted based on the number of nexthops that have been dumped so far.

2021-04-19mac80211: make ieee80211_vif_to_wdev work when the vif isn't in the driverEmmanuel Grumbach
This will allow the low level driver to get the wdev during the add_interface flow. In order to do that, remove a few checks from there and do not return NULL for vifs that were not yet added to the driver. Note that all the current callers of this helper function assume that the vif already exists: - The callers from the drivers already have a vif pointer. Before this change, ieee80211_vif_to_wdev would return NULL in some cases, but those callers don't even check they get a non-NULL pointer from ieee80211_vif_to_wdev. - The callers from net/mac80211/cfg.c assume the vif is already added to the driver as well. So, this change has no impact on existing callers of this helper function.

2021-04-19mac80211: properly process TXQ management framesJohannes Berg
My previous commit to not apply flow control to management frames that are going over TXQs (which is currently only the case for iwlwifi, I think) broke things, with iwlwifi firmware crashing on certain frames. As it turns out, that was due to the frame being too short: space for the MIC wasn't added at the end of encrypted management frames. Clearly, this is due to using the 'frags' queue - this is meant only for frames that have already been processed for TX, and the code in ieee80211_tx_dequeue() just returns them. This caused all management frames to now not get any TX processing. To fix this, use IEEE80211_TX_INTCFL_NEED_TXPROCESSING (which is currently used only in other circumstances) to indicate that the frames need processing, and clear it immediately after so that, at least in theory, MMPDUs can be fragmented.

2021-04-18netfilter: Dissect flow after packet manglingIdo Schimmel
Netfilter tries to reroute mangled packets as a different route might need to be used following the mangling. When this happens, netfilter does not populate the IP protocol, the source port and the destination port in the flow key. Therefore, FIB rules that match on these fields are ignored and packets can be misrouted. Solve this by dissecting the outer flow and populating the flow key before rerouting the packet. Note that flow dissection only happens when FIB rules that match on these fields are installed, so in the common case there should not be a penalty.

2021-04-18netfilter: nftables_offload: special ethertype handling for VLANPablo Neira Ayuso
The nftables offload parser sets FLOW_DISSECTOR_KEY_BASIC .n_proto to the ethertype field in the ethertype frame. However: - FLOW_DISSECTOR_KEY_BASIC .n_proto field always stores either IPv4 or IPv6 ethertypes. - FLOW_DISSECTOR_KEY_VLAN .vlan_tpid stores either the 802.1q and 802.1ad ethertypes. Same as for FLOW_DISSECTOR_KEY_CVLAN. This function adjusts the flow dissector to handle two scenarios: 1) FLOW_DISSECTOR_KEY_VLAN .vlan_tpid is set to 802.1q or 802.1ad. Then, transfer: - the .n_proto field to FLOW_DISSECTOR_KEY_VLAN .tpid. - the original FLOW_DISSECTOR_KEY_VLAN .tpid to the FLOW_DISSECTOR_KEY_CVLAN .tpid - the original FLOW_DISSECTOR_KEY_CVLAN .tpid to the .n_proto field. 2) .n_proto is set to 802.1q or 802.1ad. Then, transfer: - the .n_proto field to FLOW_DISSECTOR_KEY_VLAN .tpid. - the original FLOW_DISSECTOR_KEY_VLAN .tpid to the .n_proto field.

The trivial increase in the dimension of bw40_base fails as this struct must match the layout of efuse. The fix is to add the rate as an argument to rtw_get_channel_group() and set the group for channel 14 to 4 if rate <= DESC_RATE11M.

2021-04-18rsi: Use resume_noirq for SDIOMarek Vasut
The rsi_resume() does access the bus to enable interrupts on the RSI SDIO WiFi card, however when calling sdio_claim_host() in the resume path, it is possible the bus is already claimed and sdio_claim_host() spins indefinitelly. Enable the SDIO card interrupts in resume_noirq instead to prevent anything else from claiming the SDIO bus first.

2021-04-18rsi: fix comment syntax in file headersAditya Srivastava
The opening comment mark '/**' is used for highlighting the beginning of kernel-doc comments. There are some files in drivers/net/wireless/rsi which follow this syntax in their file headers, i.e. start with '/**' like comments, which causes unexpected warnings from kernel-doc. E.g., running scripts/kernel-doc -none on drivers/net/wireless/rsi/rsi_coex.h causes this warning: "warning: wrong kernel-doc identifier on line: * Copyright (c) 2018 Redpine Signals Inc." Similarly for other files too. Provide a simple fix by replacing such occurrences with general comment format, i.e., "/*", to prevent kernel-doc from parsing it.

2021-04-17r8169: keep pause settings on interface down/up cycleHeiner Kallweit
Currently, if the user changes the pause settings, the default settings will be restored after an interface down/up cycle, and also when resuming from suspend. This doesn't seem to provide the best user experience. Change this to keep user settings, and just ensure that in jumbo mode pause is disabled. Small drawback: When switching back mtu from jumbo to non-jumbo then pause remains disabled (but user can enable it using ethtool). I think that's a not too common scenario and acceptable.

2021-04-17airo: work around stack usage warningArnd Bergmann
gcc-11 with KASAN on 32-bit arm produces a warning about a function that needs a lot of stack space: drivers/net/wireless/cisco/airo.c: In function 'setup_card.constprop': drivers/net/wireless/cisco/airo.c:3960:1: error: the frame size of 1512 bytes is larger than 1400 bytes [-Werror=frame-larger-than=] Most of this is from a single large structure that could be dynamically allocated or moved into the per-device structure. However, as the callers all seem to have a fairly well bounded call chain, the easiest change is to pull out the part of the function that needs the large variables into a separate function and mark that as noinline_for_stack. This does not reduce the total stack usage, but it gets rid of the warning and requires minimal changes otherwise.

If the loop fails, the "while(trials--) {" loop will exit with "trials" set to -1. The test for that expects it to end with "trials" set to 0 so the warning message will not be printed. Fix this by changing from a post-op to a pre-op. This does mean that we only make 99 attempts instead of 100 but that's okay.
