Some of the drivers are not using channel context, but let the stack to control/switch channels instead. For such cases, driver can still remain on channel because the mac80211 stack actually supports it. The stack will check if the driver is using chan_ctx and has ops->remain_on_channel been hooked. Otherwise it will start its ROC work to remain on channel. So, even if the driver is not using chan_ctx, the driver is still capable of doing remain on channel. Signed-off-by:

Drivers that trigger roaming need to know the lifetime of the configured PMKSA for deciding whether to trigger the full or PMKSA cache based authentication. The configured PMKSA is invalid after the PMK lifetime has expired and must not be used after that and the STA needs to disassociate if the PMK expires. Hence the STA is expected to refresh the PMK with a full authentication before this happens (e.g., when reassociating to a new BSS the next time or by performing EAPOL reauthentication depending on the AKM) to avoid unnecessary disconnection. The PMK reauthentication threshold is the percentage of the PMK lifetime value and indicates to the driver to trigger a full authentication roam (without PMKSA caching) after the reauthentication threshold time, but before the PMK timer has expired. Authentication methods like SAE need to be able to generate a new PMKSA entry without having to force a disconnection after this threshold timeout. If no roaming occurs between the reauthentication threshold time and PMK lifetime expiration, disassociation is still forced. The new attributes for providing these values correspond to the dot11 MIB variables dot11RSNAConfigPMKLifetime and dot11RSNAConfigPMKReauthThreshold. This type of functionality is already available in cases where user space component is in control of roaming. This commit extends that same capability into cases where parts or all of this functionality is offloaded to the driver. Signed-off-by:

Set the NL80211_EXT_FEATURE_DEL_IBSS_STA if the interface support IBSS mode, so that stations can be reset from user space. mac80211 already deletes stations by itself, so mac80211 drivers must already support this. This has been successfully tested with ath9k. Signed-off-by:

Sometimes, userspace is able to detect that a peer silently lost its state (like, if the peer reboots). wpa_supplicant does this for IBSS-RSN by registering for auth/deauth frames, but when it detects this, it is only able to remove the encryption keys of the peer and close its port. However, the kernel also hold other state about the station, such as BA sessions, probe response parameters and the like. They also need to be resetted correctly. This patch adds the NL80211_EXT_FEATURE_DEL_IBSS_STA feature flag indicating the driver accepts deleting stations in IBSS mode, which should send a deauth and reset the state of the station, just like in mesh point mode.

In beacon protection, don't leave skb->next/prev pointing to the on-stack list, even if that's actually harmless since we don't use them again afterwards. While at it, check that the SKB on the list is still the same, as that's required here. If not, the encryption (protection) code is buggy.

Markus Theil authored
If the nl80211 control port is used before this patch, pre-auth frames (0x88c7) are send to userspace uncoditionally. While this enables userspace to only use nl80211 on the station side, it is not always useful for APs. Furthermore, pre-auth frames are ordinary data frames and not related to the control port. Therefore it should for example be possible for pre-auth frames to be bridged onto a wired network on AP side without touching userspace. For backwards compatibility to code already using pre-auth over nl80211, this patch adds a feature flag to disable this behavior, while it remains enabled by default. An additional ext. feature flag is added to detect this from userspace. Thanks to Jouni for pointing out, that pre-auth frames should be handled as ordinary data frames. Signed-off-by:

Support extended packet number cipher suites (802.1AEbw) frames handling. This does not include the needed netlink patches. * Added xpn boolean field to `struct macsec_secy`. * Added ssci field to `struct_macsec_tx_sa` (802.1AE figure 10-5). * Added ssci field to `struct_macsec_rx_sa` (802.1AE figure 10-5). * Added salt field to `struct macsec_key` (802.1AE 10.7 NOTE 1). * Created pn_t type for easy access to lower and upper halves. * Created salt_t type for easy access to the "ssci" and "pn" parts. * Created `macsec_fill_iv_xpn` function to create IV in XPN mode. * Support in PN recovery and preliminary replay check in XPN mode. In addition, according to IEEE 802.1AEbw figure 10-5, the PN of incoming frame can be 0 when XPN cipher suite is used, so fixed the function `macsec_validate_skb` to fail on PN=0 only if XPN is off.

Russell King says: ==================== net: dsa: improve serdes integration Depends on "net: mii clause 37 helpers". Andrew Lunn mentioned that the Serdes PCS found in Marvell DSA switches does not automatically update the switch MACs with the link parameters. Currently, the DSA code implements a work-around for this. This series improves the Serdes integration, making use of the recent phylink changes to support split MAC/PCS setups. One noticable improvement for userspace is that ethtool can now report the link partner's advertisement. This repost has no changes compared to the previous posting; however, the regression Andrew had found which exists even without this patch set has now been fixed by Andrew and merged into the net-next tree. ==================== Signed-off-by: -

Setting the speed independently of duplex makes little sense; the two parameters result from negotiation or fixed setup, and may have inter- dependencies. Moreover, they are always controlled via the same register - having them split means we have to read-modify-write this register twice. Combine the two operations into a single port_set_speed_duplex() operation. Not only is this more efficient, it reduces the size of the code as well. Signed-off-by:

phylink_mac_change() is supposed to be called with a 'false' argument if the link has gone down since it was last reported up; this is to ensure that link events along with renegotiation events are always correctly reported to userspace. Read the BMSR once when we have an interrupt, and report the link latched status to phylink via phylink_mac_change(). phylink will deal automatically with re-reading the link state once it has processed the link-down event.

Extend the mv88e6xxx phylink implementation down to Serdes PHYs, which handle the PCS layer of such links. - Implement phylink PCS link state reading, so that we can provide ethtool with the linkmodes and link speed in the expected manner. Note: this will only be called for in-band negotiation, which is only supported by the serdes interfaces. - Implement phylink PCS configuration, so that the in-band AN and advertisement can be configured. - Implement phylink PCS negotiation restart, so that the in-band AN can be restarted. - Implement phylink PCS link up, so that when operating out-of-band, the Serdes can be configured for the appropriate fixed speed mode.
