2020-06-12net: ipa: program upper nibbles of sequencer typeAlex Elder2-2/+6
The upper two nibbles of the sequencer type were not used for SDM845, and were assumed to be 0. But for SC7180 they are used, and so they must be programmed by ipa_endpoint_init_seq(). Fix this bug. IPA_SEQ_PKT_PROCESS_NO_DEC_NO_UCP_DMAP doesn't have a descriptive comment, so add one. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-06-12net: ipa: fix modem LAN RX endpoint idAlex Elder1-1/+1
The endpoint id assigned to the modem LAN RX endpoint for the SC7180 SoC is incorrect. The erroneous value might have been copied from SDM845 and never updated. The correct endpoint id to use for this SoC is 11. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-06-12net: ipa: program metadata mask differentlyAlex Elder1-33/+39
The way the mask value is programmed for QMAP RX endpoints was based on some wrong assumptions about the way metadata containing the QMAP mux_id value is formatted. The metadata value supplied by the modem is *not* in QMAP format, and in fact contains the mux_id we want in its (big endian) low-order byte. That byte must be written by the IPA into offset 1 of the QMAP header it inserts before the received packet. QMAP TX endpoints *do* use a QMAP header as the metadata sent with each packet. The modem assumes this, and based on that assumes the mux_id is in the second byte. To match those assumptions we must program the modem TX (QMAP) endpoint HDR register to indicate the metadata will be found at offset 0 in the message header. The previous configuration managed to work, but it was not working correctly. This patch fixes a bug whose symptom was receipt of messages containing the wrong QMAP mux_id. In fixing this, get rid of ipa_rmnet_mux_id_metadata_mask(), which was more or less defined so there was a separate place to explain what was happening as we generated the mask value. Instead, put a longer description of how this works above ipa_endpoint_init_hdr(), and define the metadata mask to use as a simple constant.

2020-06-12net/mlx5: Fix devlink objects and devlink device unregister sequenceParav Pandit1-14/+13
Current below problems exists. 1. devlink device is registered by mlx5_load_one(). But it is not unregistered by mlx5_unload_one(). This is incorrect. 2. Above issue leads to, When mlx5 PCI device is removed, currently devlink device is unregistered before devlink ports are unregistered in below ladder diagram. remove_one() mlx5_devlink_unregister() [..] devlink_unregister() <- ports are still registered! mlx5_unload_one() mlx5_unregister_device() mlx5_remove_device() mlx5e_remove() mlx5e_devlink_port_unregister() devlink_port_unregister() 3. Condition checking for registering and unregister device are not symmetric either in these routines. Hence, fix the sequence by having load and unload routines symmetric and in right order. i.e. (a) register devlink device followed by registering devlink ports (b) unregister devlink ports followed by devlink device Do this based on boot and cleanup flags instead of different conditions.

2020-06-12net/mlx5e: Fix repeated XSK usage on one channelMaxim Mikityanskiy1-0/+4
After an XSK is closed, the relevant structures in the channel are not zeroed. If an XSK is opened the second time on the same channel without recreating channels, the stray values in the structures will lead to incorrect operation of queues, which causes CQE errors, and the new socket doesn't work at all. This patch fixes the issue by explicitly zeroing XSK-related structs in the channel on XSK close. Note that those structs are zeroed on channel creation, and usually a configuration change (XDP program is set) happens on XSK open, which leads to recreating channels, so typical XSK usecases don't suffer from this issue. However, if XSKs are opened and closed on the same channel without removing the XDP program, this bug reproduces.

2020-06-12iavf: fix speed reporting over virtchnlBrett Creeley4-21/+120
Link speeds are communicated over virtchnl using an enum virtchnl_link_speed. Currently, the highest link speed is 40Gbps which leaves us unable to reflect some speeds that an ice VF is capable of. This causes link speed to be misreported on the iavf driver. Allow for communicating link speeds using Mbps so that the proper speed can be reported for an ice VF. Moving away from the enum allows us to communicate future speed changes without requiring a new enum to be added. In order to support communicating link speeds over virtchnl in Mbps the following functionality was added: - Added u32 link_speed_mbps in the iavf_adapter structure. - Added the macro ADV_LINK_SUPPORT(_a) to determine if the VF driver supports communicating link speeds in Mbps. - Added the function iavf_get_vpe_link_status() to fill the correct link_status in the event_data union based on the ADV_LINK_SUPPORT(_a) macro. - Added the function iavf_set_adapter_link_speed_from_vpe() to determine whether or not to fill the u32 link_speed_mbps or enum virtchnl_link_speed link_speed field in the iavf_adapter structure based on the ADV_LINK_SUPPORT(_a) macro. - Do not free vf_res in iavf_init_get_resources() as vf_res will be accessed in iavf_get_link_ksettings(); memset to 0 instead. This memory is subsequently freed in iavf_remove().

For groups that flag was added to struct nexthop when it should have been added to the group information. Fix by removing the flag from the nexthop struct and adding a flag to nh_group that mirrors nh_info and is really only a caching of the individual types. Add a helper, nexthop_is_fdb, for use by the vxlan code and fixup the internal code to use the flag from either nh_info or nh_group. v2 - propagate fdb_nh in remove_nh_grp_entry Fixes: 38428d68719c ("nexthop: support for fdb ecmp nexthops") Cc: Roopa Prabhu <roopa@cumulusnetworks.com> Signed-off-by: David Ahern <dsahern@kernel.org> Signed-off-by: David S.

2020-06-09ionic: wait on queue start until after IFF_UPShannon Nelson1-2/+2
The netif_running() test looks at __LINK_STATE_START which gets set before ndo_open() is called, there is a window of time between that and when the queues are actually ready to be run. If ionic_check_link_status() notices that the link is up very soon after netif_running() becomes true, it might try to run the queues before they are ready, causing all manner of potential issues. Since the netdev->flags IFF_UP isn't set until after ndo_open() returns, we can wait for that before we allow ionic_check_link_status() to start the queues. On the way back to close, __LINK_STATE_START is cleared before calling ndo_stop(), and IFF_UP is cleared after. Both of these need to be true in order to safely stop the queues from ionic_check_link_status().

2020-06-09net: change addr_list_lock back to static keyCong Wang7-9/+22
The dynamic key update for addr_list_lock still causes troubles, for example the following race condition still exists: CPU 0: CPU 1: (RCU read lock) (RTNL lock) dev_mc_seq_show() netdev_update_lockdep_key() -> lockdep_unregister_key() -> netif_addr_lock_bh() because lockdep doesn't provide an API to update it atomically. Therefore, we have to move it back to static keys and use subclass for nest locking like before. In commit 1a33e10e4a95 ("net: partially revert dynamic lockdep key changes"), I already reverted most parts of commit ab92d68fc22f ("net: core: add generic lockdep keys"). This patch reverts the rest and also part of commit f3b0a18bb6cb ("net: remove unnecessary variables and callback"). After this patch, addr_list_lock changes back to using static keys and subclasses to satisfy lockdep. Thanks to dev->lower_level, we do not have to change back to ->ndo_get_lock_subclass(). And hopefully this reduces some syzbot lockdep noises too.

While trying to use the lantiq_gswip driver on one of my boards I made a mistake when specifying the phy-mode (because the out-of-tree driver wants phy-mode "gmii" or "mii" for the internal PHYs). In this case the following error is printed multiple times: Unsupported interface: 3 While it gives at least a hint at what may be wrong it is not very user friendly. Print the human readable phy-mode and also which port is configured incorrectly (this hardware supports ports 0..6) to improve the cases where someone made a mistake.

2020-06-08mlxsw: core: Use different get_trend() callbacks for different thermal zonesVadim Pasternak1-4/+19
The driver registers three different types of thermal zones: For the ASIC itself, for port modules and for gearboxes. Currently, all three types use the same get_trend() callback which does not work correctly for the ASIC thermal zone. The callback assumes that the device data is of type 'struct mlxsw_thermal_module', whereas for the ASIC thermal zone 'struct mlxsw_thermal' is passed as device data. Fix this by using one get_trend() callback for the ASIC thermal zone and another for the other two types.

2020-06-07net: dp83869: Reset return variable if PHY strap is readDan Murphy1-0/+3
When the PHY's strap register is read to determine if lane swapping is needed the phy_read_mmd returns the value back into the ret variable. If the call to read the strap fails the failed value is returned. If the call to read the strap is successful then ret is possibly set to a non-zero positive number. Without reseting the ret value to 0 this will cause the parse DT function to return a failure.

2020-06-06firmware/dmi: Report DMI Bios & EC firmware releaseErwan Velu2-0/+36
Some vendors like HPe or Dell, encode the release version of their BIOS in the "System BIOS {Major|Minor} Release" fields of Type 0. This information is used to know which bios release actually runs. It could be used for some quirks, debugging sessions or inventory tasks. A typical output for a Dell system running the 65.27 bios is : [root@t1700 ~]# cat /sys/devices/virtual/dmi/id/bios_release 65.27 [root@t1700 ~]# Servers that have a BMC encode the release version of their firmware in the "Embedded Controller Firmware {Major|Minor} Release" fields of Type 0. This information is used to know which BMC release actually runs. It could be used for some quirks, debugging sessions or inventory tasks. A typical output for a Dell system running the 3.75 bmc release is : [root@t1700 ~]# cat /sys/devices/virtual/dmi/id/ec_firmware_release 3.75 [root@t1700 ~]# Signed-off-by: Erwan Velu <e.velu@criteo.com> Signed-off-by: Jean Delvare <jdelvare@suse.de>
2020-06-06NTB: perf: Fix race condition when run with ntb_testLogan Gunthorpe1-2/+8
When running ntb_test, the script tries to run the ntb_perf test immediately after probing the modules. Since adding multi-port support, this fails seeing the new initialization procedure in ntb_perf can not complete instantly. To fix this we add a completion which is waited on when a test is started. In this way, run can be written any time after the module is loaded and it will wait for the initialization to complete instead of sending an error.

2020-06-06NTB: perf: Fix support for hardware that doesn't have port numbersLogan Gunthorpe1-0/+10
Legacy drivers do not have port numbers (but is reliably only two ports) and was broken by the recent commit that added mult-port support to ntb_perf. This is especially important to support the cross link topology which is perfectly symmetric and cannot assign unique port numbers easily. Hardware that returns zero for both the local port and the peer should just always use gidx=0 for the only peer.
