2021-02-11Revert "net-loopback: set lo dev initial state to UP"Petr Machata
In commit c9dca822c729 ("net-loopback: set lo dev initial state to UP"), linux started automatically bringing up the loopback device of a newly created namespace. However, an existing user script might reasonably have the following stanza when creating a new namespace -- and in fact at least tools/testing/selftests/net/fib_nexthops.sh in Linux's very own testsuite does: # set -e # ip netns add foo # ip -netns foo addr add 127.0.0.1/8 dev lo # ip -netns foo link set lo up # set +e This will now fail, because the kernel reasonably rejects "ip addr add" of a duplicate address. The described change of behavior therefore constitutes a breakage. Revert it.

2021-02-11net: phy: introduce phydev->portMichael Walle
At the moment, PORT_MII is reported in the ethtool ops. This is odd because it is an interface between the MAC and the PHY and no external port. Some network card drivers will overwrite the port to twisted pair or fiber, though. Even worse, the MDI/MDIX setting is only used by ethtool if the port is twisted pair. Set the port to PORT_TP by default because most PHY drivers are copper ones. If there is fibre support and it is enabled, the PHY driver will set it to PORT_FIBRE. This will change reporting PORT_MII to either PORT_TP or PORT_FIBRE; except for the genphy fallback driver.

2021-02-11arm/xen: Don't probe xenbus as part of an early initcallJulien Grall
After Commit 3499ba8198cad ("xen: Fix event channel callback via INTX/GSI"), xenbus_probe() will be called too early on Arm. This will recent to a guest hang during boot. If the hang wasn't there, we would have ended up to call xenbus_probe() twice (the second time is in xenbus_probe_initcall()). We don't need to initialize xenbus_probe() early for Arm guest. Therefore, the call in xen_guest_init() is now removed. After this change, there is no more external caller for xenbus_probe(). So the function is turned to a static one. Interestingly there were two prototypes for it.

When the ath10k report it with HTT_TX_COMPL_STATE_DISCARD, it will be set without flag IEEE80211_TX_STAT_ACK, then mac80211 should try the next authentication immeditely, but in fact mac80211 wait 1 second for it, the reason is ieee80211_is_auth(fc) in ieee80211_sta_work check fail for the sk_buff which is not restored, the data of sk_buff is not the begin of ieee80211_hdr, in fact it is the begin of htt_cmd_hdr. dmesg without this patch, it wait 1 second for the next retry when ath10k report without IEEE80211_TX_STAT_ACK for authentication: [ 6973.883116] wlan0: send auth to 5e:6f:2b:0d:fb:d7 (try 1/3) [ 6974.705471] wlan0: send auth to 5e:6f:2b:0d:fb:d7 (try 2/3) [ 6975.712962] wlan0: send auth to 5e:6f:2b:0d:fb:d7 (try 3/3) Restore the sk_buff make mac8011 retry the next authentication immeditely which meet logic of mac80211. dmesg with this patch, it retry the next immeditely when ath10k report without IEEE80211_TX_STAT_ACK for authentication: [ 216.734813] wlan0: send auth to 5e:6f:2b:0d:fb:d7 (try 1/3) [ 216.739914] wlan0: send auth to 5e:6f:2b:0d:fb:d7 (try 2/3) [ 216.745874] wlan0: send auth to 5e:6f:2b:0d:fb:d7 (try 3/3) Tested-on: QCA6174 hw3.2 SDIO WLAN.RMH.4.4.1-00049 Signed-off-by: Wen Gong <wgong@codeaurora.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org> Link: https://lore.kernel.org/r/1612839530-2263-1-git-send-email-wgong@codeaurora.org
2021-02-11wilc1000: Fix use of void pointer as a wrong struct typeVsevolod Kozlov
ac_classify() expects a struct sk_buff* as its second argument, which is a member of struct tx_complete_data. priv happens to be a pointer to struct tx_complete_data, so passing it directly to ac_classify() leads to wrong behaviour and occasional panics. Since there is only one caller of wilc_wlan_txq_add_net_pkt and it already knows the type behind this pointer, and the structure is already in the header file, change the function signature to use the real type instead of void* in order to prevent confusion.
