2019-05-01mt76usb: move mt76u_buf->done to queue entryStanislaw Gruszka
mt76_queue_entry has alreay one bool variable, adding new one will not increase it's size. Removing ->done filed from mt76u_buf will allow to use urb directly in mt76usb code. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>

2019-05-01mt76x02u: add mt76_release_buffered_framesStanislaw Gruszka
Create software MT_TXQ_PSD queue for USB and map it to MT_TXQ_VO since we do not have USB endpoint for PSD. This should make mt76_release_buffered_frames() work by sending released frames via MT_TXQ_VO. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-05-01mt76x02: make beacon slots bigger for USBStanislaw Gruszka
Since we sent PS buffered frames via beacon memory we need to make beacon slots bigger. That imply we will also need to decrease number of slots as beacon SRAM memory is limited to 8kB. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-05-01mt76x02u: implement pre TBTT work for USBStanislaw Gruszka
Program beacons data and PS buffered frames on TBTT work for USB. We do not have MT_TXQ_PSD queue available via USB endpoints. The way we can send PS broadcast frames in timely manner before PS stations go sleep again is program them in beacon data area. Hardware do not modify those frames since TXWI is properly configured. mt76x02_mac_set_beacon() already handle this and free no longer used frames.

2019-04-30ipv6: fix races in ip6_dst_destroy()Eric Dumazet
We had many syzbot reports that seem to be caused by use-after-free of struct fib6_info. ip6_dst_destroy(), fib6_drop_pcpu_from() and rt6_remove_exception() are writers vs rt->from, and use non consistent synchronization among themselves. Switching to xchg() will solve the issues with no possible lockdep issues.

2019-04-30Merge branch 'Convert-mv88e6060-to-mdio-device'David S. Miller
Andrew Lunn says: ==================== Convert mv88e6060 to mdio device This patchset builds upon the previous patches to mv88e6060. It adds support for probing the switch as an MDIO device and then removes the legacy probe method. Since this is the last device supporting legacy probe, this allows legacy probe to be removed, originally planned to be removed in 4.17, but took a bit longer. This change to the mv88e6060 is more risky than the previous patchset. Some attempts to test it have been made, by hacking the driver to match on an mv88e6352 so that it probes. These changes are all about probe, so it is a reasonable test. But testing on a real mv88e6060 would be great. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2019-04-30Merge branch 'dsa-core-vlan'David S. Miller
Vladimir Oltean says: ==================== Improvements to DSA core VLAN manipulation In preparation of submitting the NXP SJA1105 driver, the Broadcom b53 and Mediatek mt7530 drivers have been found to apply some VLAN workarounds that are needed in the new driver as well. Therefore this patchset is mostly simply promoting the DSA driver workarounds for VLAN to the generic code. The b53 driver was applying a few workarounds in order to convince DSA that its vlan_filtering setting is not really per-port. This is now simply set by the driver via a DSA variable at probe time. The sja1105 driver will be a second user of this. The mt7530 was also keeping track of when the .port_vlan_filtering callback was being called. Remove the kept state from this driver and simplify dealing with vlan_filtering in the generic case. TODO: Find the best way to deal generically with the situation described below (discussion at https://lkml.org/lkml/2019/4/16/1355): > > +Segregating the switch ports in multiple bridges is supported (e.g. 2 + 2), but > > +all bridges should have the same level of VLAN awareness (either both have > > +``vlan_filtering`` 0, or both 1).

Since enslaving ports into a bridge > comes after the network device was already made available for use, maybe > you should force the carrier down or something along those lines as soon > as a port is enslaved into a bridge with vlan_filtering=1 to make this > more predictable for the user? ==================== Signed-off-by: David S.

2019-04-30net: dsa: Skip calling .port_vlan_filtering on no changeVladimir Oltean
