2019-11-01net/mlx5: Support lockless FTE read lookupsParav Pandit
During connection tracking offloads with high number of connections, (40K connections per second), flow table group lock contention is observed. To improve the performance by reducing lock contention, lockless FTE read lookup is performed as described below. Each flow table entry is refcounted. Flow table entry is removed when refcount drops to zero. rhash table allows rcu protected lookup. Each hash table entry insertion and removal is write lock protected. Hence, it is possible to perform lockless lookup in rhash table using following scheme. (a) Guard FTE entry lookup per group using rcu read lock. (b) Before freeing the FTE entry, wait for all readers to finish accessing the FTE. Below example of one reader and write in parallel racing, shows protection in effect with rcu lock. lookup_fte_locked() rcu_read_lock(); search_hash_table() existing_flow_group_write_lock(); tree_put_node(fte) drop_ref_cnt(fte) del_sw_fte(fte) del_hash_table_entry(); call_rcu(); existing_flow_group_write_unlock(); get_ref_cnt(fte) fails rcu_read_unlock(); rcu grace period(); [..] kmem_cache_free(fte); Signed-off-by: Parav Pandit <parav@mellanox.com> Reviewed-by: Mark Bloch <markb@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>

Lyude Paul fixes an issue where a fatal read error occurs when the device is unplugged from the machine. So change the read error into a warn while the device is still present. Manfred Rudigier found that the i350 device was not apart of the "Media Auto Sense" feature, yet the device supports it. So add the missing i350 device to the check and fix an issue where the media auto sense would flip/flop when no cable was connected to the port causing spurious kernel log messages. I fixed an issue where the fix to resolve receive buffer starvation was applied in more than one place in the driver, one being the incorrect location in the i40e driver. Wenwen Wang fixes a potential memory leak in e1000 where allocated memory is not properly cleaned up in one of the error paths. Jonathan Neuschäfer cleans up the driver documentation to be consistent and remove the footnote reference, since the footnote no longer exists in the documentation. Igor Pylypiv cleans up a duplicate clearing of a bit, no need to clear it twice. v2: Fixed alignment issue in patch 3 of the series based on community feedback. ==================== Signed-off-by: David S.

2019-11-01net/mlx5: E-switch, Enable metadata on own vportParav Pandit
Currently on ECPF, metadata is enabled on the ECPF vport = 0xfffe (manager vport). Metadata when supported, must be enabled on own vport which is used to pass metadata to vport of NIC Rx Flow Table. Due to this error, traffic tagged by ingress ACL is not processed correctly at NIC rx flow table level which is supposed to work on metadata tag. Hence, instead of working on eswitch manager vport, always working on eswitch own vport regardless of PF or ECPF. Given that mlx5_eswitch_query/modify_esw_vport_context() is used to access other vport in legacy mode and own vport settings in switchdev mode, extend low level API to explicitly specify other_vport.

When eswitch is disabled, vport event handler is unregistered.

It is also necessary to synchronize with already scheduled vport event. This is already achieved using below sequence. mlx5_eswitch_event_handlers_unregister() [..] flush_workqueue() Hence, (a) Remove vport->enabled check in eswitch_vport_event() which doesn't make any sense.

2019-11-01igb: Fix constant media auto sense switching when no cable is connectedManfred Rudigier
At least on the i350 there is an annoying behavior that is maybe also present on 82580 devices, but was probably not noticed yet as MAS is not widely used. If no cable is connected on both fiber/copper ports the media auto sense code will constantly swap between them as part of the watchdog task and produce many unnecessary kernel log messages. The swap code responsible for this behavior (switching to fiber) should not be executed if the current media type is copper and there is no signal detected on the fiber port. In this case we can safely wait until the AUTOSENSE_EN bit is cleared.

Most of them are for iwlwifi but important fixes also for rtlwifi and mt76, the overflow fix for rtlwifi being most important. iwlwifi * fix merge damage on earlier patch * various fixes to device id handling * fix scan config command handling which caused firmware asserts rtlwifi * fix overflow on P2P IE handling * don't deliver too small frames to mac80211 mt76 * disable PCIE_ASPM * fix buffer DMA unmap on certain cases ==================== Signed-off-by: David S.

Nikolay Aleksandrov says: ==================== net: bridge: minor followup optimizations After the converted flags to bitops we can take advantage of the flags assignment and remove one test and three atomic bitops from the learning paths (patch 01 and patch 02), patch 03 restores the unlikely() when taking over HW learned entries. v2: a clean export of the latest set version ==================== Signed-off-by: David S.

2019-11-01net: bridge: fdb: restore unlikely() when taking over externally added entriesNikolay Aleksandrov
Taking over hw-learned entries is not a likely scenario so restore the unlikely() use for the case of SW taking over externally learned entries. Signed-off-by: Nikolay Aleksandrov <nikolay@cumulusnetworks.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-11-01net: bridge: fdb: avoid two atomic bitops in br_fdb_external_learn_add()Nikolay Aleksandrov
If we setup the fdb flags prior to calling fdb_create() we can avoid two atomic bitops when learning a new entry. Signed-off-by: Nikolay Aleksandrov <nikolay@cumulusnetworks.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-11-01net: bridge: fdb: br_fdb_update can take flags directlyNikolay Aleksandrov
If we modify br_fdb_update() to take flags directly we can get rid of one test and one atomic bitop in the learning path. Signed-off-by: Nikolay Aleksandrov <nikolay@cumulusnetworks.com> Signed-off-by: David S. Miller <davem@davemloft.net>

git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 fixes from Will Deacon: "These are almost exclusively related to CPU errata in CPUs from Broadcom and Qualcomm where the workarounds were either not being enabled when they should have been or enabled when they shouldn't have been. The only "interesting" fix is ensuring that writeable, shared mappings are initially mapped as clean since we inadvertently broke the logic back in v4.14 and then noticed the problem via code inspection the other day. The only critical issue we have outstanding is a sporadic NULL dereference in the scheduler, which doesn't appear to be arm64-specific and PeterZ is tearing his hair out over it at the moment. Summary: - Enable CPU errata workarounds for Broadcom Brahma-B53 - Enable CPU errata workarounds for Qualcomm Hydra/Kryo CPUs - Fix initial dirty status of writeable, shared mappings" * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: arm64: apply ARM64_ERRATUM_843419 workaround for Brahma-B53 core arm64: Brahma-B53 is SSB and spectre v2 safe arm64: apply ARM64_ERRATUM_845719 workaround for Brahma-B53 core arm64: cpufeature: Enable Qualcomm Falkor errata 1009 for Kryo arm64: cpufeature: Enable Qualcomm Falkor/Kryo errata 1003 arm64: Ensure VM_WRITE|VM_SHARED ptes are clean by default
