2019-04-15bonding: fix event handling for stacked bondsSabrina Dubroca1-1/+5
When a bond is enslaved to another bond, bond_netdev_event() only handles the event as if the bond is a master, and skips treating the bond as a slave. This leads to a refcount leak on the slave, since we don't remove the adjacency to its master and the master holds a reference on the slave. Reproducer: ip link add bondL type bond ip link add bondU type bond ip link set bondL master bondU ip link del bondL No "Fixes:" tag, this code is older than git history.

2019-04-14qed: Fix the DORQ's attentions handlingDenis Bolotin2-16/+48
Separate the overflow handling from the hardware interrupt status analysis. The interrupt status is a single register and is common for all PFs. The first PF reading the register is not necessarily the one who overflowed. All PFs must check their overflow status on every attention. In this change we clear the sticky indication in the attention handler to allow doorbells to be processed again as soon as possible, but running the doorbell recovery is scheduled for the periodic handler to reduce the time spent in the attention handler. Checking the need for DORQ flush was changed to "db_bar_no_edpm" because qed_edpm_enabled()'s result could change dynamically and might have prevented a needed flush.

2019-04-14qed: Fix missing DORQ attentionsDenis Bolotin3-3/+20
When the DORQ (doorbell block) is overflowed, all PFs get attentions at the same time. If one PF finished handling the attention before another PF even started, the second PF might miss the DORQ's attention bit and not handle the attention at all. If the DORQ attention is missed and the issue is not resolved, another attention will not be sent, therefore each attention is treated as a potential DORQ attention. As a result, the attention callback is called more frequently so the debug print was moved to reduce its quantity. The number of periodic doorbell recovery handler schedules was reduced because it was the previous way to mitigating the missed attention issue.

2019-04-14qed: Delete redundant doorbell recovery typesDenis Bolotin4-51/+31
DB_REC_DRY_RUN (running doorbell recovery without sending doorbells) is never used. DB_REC_ONCE (send a single doorbell from the doorbell recovery) is not needed anymore because by running the periodic handler we make sure we check the overflow status later instead. This patch is needed because in the next patches, the only doorbell recovery type being used is DB_REC_REAL_DEAL, and the fixes are much cleaner without this enum.

2019-04-12qede: fix write to free'd pointer error and double free of ptpColin Ian King1-4/+3
The err2 error return path calls qede_ptp_disable that cleans up on an error and frees ptp. After this, the free'd ptp is dereferenced when ptp->clock is set to NULL and the code falls-through to error path err1 that frees ptp again. Fix this by calling qede_ptp_disable and exiting via an error return path that does not set ptp->clock or kfree ptp.

2019-04-12mt76: mt7603: fix sequence number assignmentFelix Fietkau3-43/+18
If the MT_TXD3_SN_VALID flag is not set in the tx descriptor, the hardware assigns the sequence number. However, the rest of the code assumes that the sequence number specified in the 802.11 header gets transmitted. This was causing issues with the aggregation setup, which worked for the initial one (where the sequence numbers were still close), but not for further teardown/re-establishing of sessions. Additionally, the overwrite of the TID sequence number in WTBL2 was resetting the hardware assigned sequence numbers, causing them to drift further apart. Fix this by using the software assigned sequence numbers Signed-off-by: Felix Fietkau <nbd@nbd.name> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2019-04-10mlxsw: spectrum_buffers: Add a multicast pool for Spectrum-2Ido Schimmel1-8/+11
In Spectrum-1, when a multicast packet is admitted to the shared buffer it increases the quotas of all the ports and {port, TC} to which it is forwarded to. The above means that multicast packets are accounted multiple times in the shared buffer and can therefore cause the associated shared buffer pool to fill up very quickly. To work around this issue, commit e83c045e53d7 ("mlxsw: spectrum_buffers: Configure MC pool") added a dedicated multicast pool in which multicast packets are accounted. The issue is not present in Spectrum-2, but in order to be backward compatible with Spectrum-1, its default behavior is to allow a multicast packet to increase multiple egress quotas instead of one. Until the new (non-backward compatible) mode is supported, configure a dedicated multicast pool as in Spectrum-1.

This reverts commit b820e6fb0978f9c2ac438c199d2bb2f35950e9c9. Prior the commit we are reverting, checksum unnecessary was only set when both the L3 OK and L4 OK bits are set on the CQE. This caused packets of IP protocols such as SCTP which are not dealt by the current HW L4 parser (hence the L4 OK bit is not set, but the L4 header type none bit is set) to go through the checksum none code, where currently we wrongly report checksum unnecessary for them, a regression. Fix this by a revert. Note that on our usual track we report checksum complete, so the revert isn't expected to have any notable performance impact. Also, when we are not on the checksum complete track, the L4 protocols for which we report checksum none are not high performance ones, we will still report checksum unnecessary for UDP/TCP.

There is logic to check that the RX/TPA consumer index is the expected index to work around a hardware problem. However, the potentially bad consumer index is first used to index into an array to reference an entry. This can potentially crash if the bad consumer index is beyond legal range. Improve the logic to use the consumer index for dereferencing after the validity check and log an error message.

2019-04-08net: macb driver, check for SKBTX_HW_TSTAMPPaul Thomas1-1/+3
Make sure SKBTX_HW_TSTAMP (i.e. SOF_TIMESTAMPING_TX_HARDWARE) has been enabled for this skb. It does fix the issue where normal socks that aren't expecting a timestamp will not wake up on select, but when a user does want a SOF_TIMESTAMPING_TX_HARDWARE it does work.

2019-04-08qlogic: qlcnic: fix use of SPEED_UNKNOWN ethtool constantMichael Zhivich1-1/+1
qlcnic driver uses u16 to store SPEED_UKNOWN ethtool constant, which is defined as -1, resulting in value truncation and thus incorrect test results against SPEED_UNKNOWN. For example, the following test will print "False": u16 speed = SPEED_UNKNOWN; if (speed == SPEED_UNKNOWN) printf("True"); else printf("False"); Change storage of speed to use u32 to avoid this issue.

2019-04-08r8169: disable ASPM againHeiner Kallweit1-0/+6
There's a significant number of reports that re-enabling ASPM causes different issues, ranging from decreased performance to system not booting at all. This affects only a minority of users, but the number of affected users is big enough that we better switch off ASPM again. This will hurt notebook users who are not affected by the issues, they may see decreased battery runtime w/o ASPM. With the PCI core folks is being discussed to add generic sysfs attributes to control ASPM. Once this is in place brave enough users can re-enable ASPM on their system.

2019-04-08mac80211: make ieee80211_schedule_txq schedule empty TXQsFelix Fietkau3-4/+7
Currently there is no way for the driver to signal to mac80211 that it should schedule a TXQ even if there are no packets on the mac80211 part of that queue. This is problematic if the driver has an internal retry queue to deal with software A-MPDU retry. This patch changes the behavior of ieee80211_schedule_txq to always schedule the queue, as its only user (ath9k) seems to expect such behavior already: it calls this function on tx status and on powersave wakeup whenever its internal retry queue is not empty. Also add an extra argument to ieee80211_return_txq to get the same behavior. This fixes an issue on ath9k where tx queues with packets to retry (and no new packets in mac80211) would not get serviced.

If we just set this to 2048, and have multiple limits you can select from, the total number might run over and cause a warning in cfg80211. This doesn't make sense, so we just calculate the total max_interfaces now.
