2019-11-22virt_wifi: fix use-after-free in virt_wifi_newlink()Taehee Yoo
When virt_wifi interface is created, virt_wifi_newlink() is called and it calls register_netdevice(). if register_netdevice() fails, it internally would call ->priv_destructor(), which is virt_wifi_net_device_destructor() and it frees netdev. but virt_wifi_newlink() still use netdev. So, use-after-free would occur in virt_wifi_newlink(). Test commands: ip link add dummy0 type dummy modprobe bonding ip link add bonding_masters link dummy0 type virt_wifi Splat looks like: [ 202.220554] BUG: KASAN: use-after-free in virt_wifi_newlink+0x88b/0x9a0 [virt_wifi] [ 202.221659] Read of size 8 at addr ffff888061629cb8 by task ip/852 [ 202.222896] CPU: 1 PID: 852 Comm: ip Not tainted 5.4.0-rc5 #3 [ 202.223765] Hardware name: innotek GmbH VirtualBox/VirtualBox, BIOS VirtualBox 12/01/2006 [ 202.225073] Call Trace: [ 202.225532] dump_stack+0x7c/0xbb [ 202.226869] print_address_description.constprop.5+0x1be/0x360 [ 202.229362] __kasan_report+0x12a/0x16f [ 202.230714] kasan_report+0xe/0x20 [ 202.232595] virt_wifi_newlink+0x88b/0x9a0 [virt_wifi] [ 202.233370] __rtnl_newlink+0xb9f/0x11b0 [ 202.244909] rtnl_newlink+0x65/0x90 [ ... ] Cc: stable@vger.kernel.org Fixes: c7cdba31ed8b ("mac80211-next: rtnetlink wifi simulation device") Signed-off-by: Taehee Yoo <ap420073@gmail.com> Link: https://lore.kernel.org/r/20191121122645.9355-1-ap420073@gmail.com [trim stack dump a bit] Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2019-11-20Revert "mt76: mt76x0e: don't use hw encryption for MT7630E"Stanislaw Gruszka
This reverts commit 34b0e9b767bfa09ae233ca0d6ceb299bf2e24600. Since commit 7bd0650be63c ("mt76: dma: fix buffer unmap with non-linear skbs") is no longer necessary to disable HW encryption for MT7630E. Disabling HW encryption helped previously because somehow fragmented skb's are not created if mac80211 encrypt frames, so buffer unmap bug of non-linear skbs was not triggered. Now since this bug is properly fixed by commit 7bd0650be63c ("mt76: dma: fix buffer unmap with non-linear skbs") , we can enable HW encryption back.

2019-11-20mt76: mt7615: introduce mt7615_mac_wtbl_update routineLorenzo Bianconi
Introduce mt7615_mac_wtbl_update utility routine in order to update WTBL update register Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-11-20mt76: mt7615: fix survey channel busy timeFelix Fietkau
Like on mt7603, MIB status register 16 tracks CCA time, but does not include tx time. Switch to status register 9 to includ NAV and tx time as well. Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-11-20mt76: mt7615: report tx_time, bss_rx and busy time to mac80211Lorenzo Bianconi
Report tx time/rx time and obss time from hw mib counters to fill survey info requested by mac80211 Co-developed-by: Felix Fietkau <nbd@nbd.name> Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-11-20mt76: mt76x02: track approximate tx airtime for airtime fairness and surveyFelix Fietkau
Estimate by calculating duration for EWMA packet size + estimated A-MPDU length on tx status events Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-11-20mt76: mt76x02: move MT_CH_TIME_CFG init to mt76x02_mac_cc_resetFelix Fietkau
Reduces code duplication and adds missing bits for USB variants Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-11-20mt76: unify channel survey update codeFelix Fietkau
Host time is used to calculate the channel active time on mt7603 and mt7615. Use the same on mt76x02 and move the lock to core code to get rid of some duplicated code. Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-11-20mt76: mt7603: switch to a different counter for survey busy timeFelix Fietkau
MT_MIB_STAT_PSCCA only counts rx CCA busy time, which does not include tx time. MT_MIB_STAT_CCA counts full busy time, including Rx, Tx and NAV Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-11-20mt76: mt7603: track tx airtime for airtime fairness and surveyFelix Fietkau
Poll per-station hardware counters after tx status events Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-11-20mt76: track rx airtime for airtime fairness and surveyFelix Fietkau
Report total rx airtime for valid stations as BSS rx time in survey mt7615 is left out for now, it will be supported later by reading hardware counters instead of calculating airtime in software Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-11-20mt76: store current channel survey_state in struct mt76_devFelix Fietkau
Move mt76_channel_state() from mt76.h to mac80211.c Preparation for updating channel state from more places in the drivers/core Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-11-20mt76: rename mt76_driver_ops txwi_flags to drv_flags and include tx aligned4Felix Fietkau
This reduces the struct size and is useful for adding more flags later Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-11-20mt76: report rx a-mpdu subframe statusFelix Fietkau
This can be used in monitor mode to figure out which subframes were sent as part of which A-MPDU Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-11-20mt76: mt7603: remove q_rx field from struct mt7603_devFelix Fietkau
It is no longer used Signed-off-by: Felix Fietkau <nbd@nbd.name>
2019-11-20mt76: mt7603: collect aggregation statsLorenzo Bianconi
Introduce ampdu_stat entry in mt7603 debugfs in order to dump 802.11 aggr cumulative statistics Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Felix Fietkau <nbd@nbd.name>
