2019-07-29net: hns3: Add support for using order 1 pages with a 4K bufferYunsheng Lin2-8/+17
Hardware supports 0.5K, 1K, 2K, 4K RX buffer size, the RX buffer can not be reused because the hns3_page_order return 0 when page size and RX buffer size are both 4096. So this patch changes the hns3_page_order to return 1 when RX buffer is greater than half of the page size and page size is less the 8192, and dev_alloc_pages has already been used to allocate the compound page for RX buffer. This patch also changes hnae3_* to hns3_* for page order and RX buffer size calculation because they are used in hns3 module.

2019-07-29mac80211: add support for the ADDBA extension elementJohn Crispin4-11/+66
HE allows peers to negotiate the aggregation fragmentation level to be used during transmission. The level can be 1-3. The Ext element is added behind the ADDBA request inside the action frame. The responder will then reply with the same level or a lower one if the requested one is not supported. This patch only handles the negotiation part as the ADDBA frames get passed to the ATH11k firmware, which does the rest of the magic for us aswell as generating the requests.

2019-07-29cfg80211: fix duplicated scan entries after channel switchSergey Matyukevich3-1/+82
When associated BSS completes channel switch procedure, its channel record needs to be updated. The existing mac80211 solution was extended to cfg80211 in commit 5dc8cdce1d72 ("mac80211/cfg80211: update bss channel on channel switch"). However that solution still appears to be incomplete as it may lead to duplicated scan entries for associated BSS after channel switch. The root cause of the problem is as follows. Each BSS entry is included into the following data structures: - bss list rdev->bss_list - bss search tree rdev->bss_tree Updating BSS channel record without rebuilding bss_tree may break tree search since cmp_bss considers all of the following: channel, bssid, ssid. When BSS channel is updated, but its location in bss_tree is not updated, then subsequent search operations may fail to locate this BSS since they will be traversing bss_tree in wrong direction. As a result, for scan performed after associated BSS channel switch, cfg80211_bss_update may add the second entry for the same BSS to both bss_list and bss_tree, rather then update the existing one. To summarize, if BSS channel needs to be updated, then bss_tree should be rebuilt in order to put updated BSS entry into a proper location. This commit suggests the following straightforward solution: - if new entry has been already created for BSS after channel switch, then use its IEs to update known BSS entry and then remove new entry completely - use rb_erase/rb_insert_bss reinstall updated BSS in bss_tree - for nontransmit BSS entry, the whole transmit BSS hierarchy is updated Signed-off-by: Sergey Matyukevich <sergey.matyukevich.os@quantenna.com> Link: https://lore.kernel.org/r/20190726163922.27509-3-sergey.matyukevich.os@quantenna.com Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2019-07-28mlx4/en_netdev: allow offloading VXLAN over VLANDavide Caratti1-26/+17
ConnectX-3 Pro can offload transmission of VLAN packets with VXLAN inside: enable tunnel offloads in dev->vlan_features, like it's done with other NIC drivers (e.g. be2net and ixgbe). It's no more necessary to change dev->hw_enc_features when VXLAN are added or removed, since .ndo_features_check() already checks for VXLAN packet where the UDP destination port matches the configured value. Just set dev->hw_enc_features when the NIC is initialized, so that overlying VLAN can correctly inherit the tunnel offload capabilities.

2019-07-26cfg80211: give all multi-BSSID BSS entries the same timestampJohannes Berg1-2/+5
If we just read jiffies over and over again, a non-transmitting entry may have a newer timestamp than the transmitting one, leading to possible confusion on expiry. Give them all the same timestamp when creating them.

2019-07-26cfg80211: don't parse MBSSID if transmitting BSS isn't createdJohannes Berg1-1/+3
Don't parse the multi-BSSID structures if we couldn't even create their transmitting BSS, this would confuse all of our tracking. This also means that non_tx_data->tx_bss will never be NULL, so we can clean up a little bit.

2019-07-26cfg80211: no need to check return value of debugfs_create functionsGreg Kroah-Hartman1-11/+6
When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this.

2019-07-26mac80211: AMPDU handling for rekeys with Extended Key IDAlexander Wetzel3-6/+14
Extended Key ID allows A-MPDU sessions while rekeying as long as each A-MPDU aggregates only MPDUs with one keyid together. Drivers able to segregate MPDUs accordingly can tell mac80211 to not stop A-MPDU sessions when rekeying by setting the new flag IEEE80211_HW_AMPDU_KEYBORDER_SUPPORT.

2019-07-26mac80211: Simplify Extended Key ID APIAlexander Wetzel4-32/+14
1) Drop IEEE80211_HW_EXT_KEY_ID_NATIVE and let drivers directly set the NL80211_EXT_FEATURE_EXT_KEY_ID flag. 2) Drop IEEE80211_HW_NO_AMPDU_KEYBORDER_SUPPORT and simply assume all drivers are unable to handle A-MPDU key borders. The new Extended Key ID API now requires all mac80211 drivers to set NL80211_EXT_FEATURE_EXT_KEY_ID when they implement set_key() and can handle Extended Key ID. For drivers not providing set_key() mac80211 itself enables Extended Key ID support, using the internal SW crypto services.
