2019-08-06be2net: Signal that the device cannot transmit during reconfigurationBenjamin Poirier
[ Upstream commit 7429c6c0d9cb086d8e79f0d2a48ae14851d2115e ] While changing the number of interrupt channels, be2net stops adapter operation (including netif_tx_disable()) but it doesn't signal that it cannot transmit. This may lead dev_watchdog() to falsely trigger during that time. Add the missing call to netif_carrier_off(), following the pattern used in many other drivers. netif_carrier_on() is already taken care of in be_open().

2018-11-04be2net: don't flip hw_features when VXLANs are added/deletedDavide Caratti
[ Upstream commit 2d52527e80c2dc0c5f43f50adf183781262ec565 ] the be2net implementation of .ndo_tunnel_{add,del}() changes the value of NETIF_F_GSO_UDP_TUNNEL bit in 'features' and 'hw_features', but it forgets to call netdev_features_change(). Moreover, ethtool setting for that bit can potentially be reverted after a tunnel is added or removed. GSO already does software segmentation when 'hw_enc_features' is 0, even if VXLAN offload is turned on. In addition, commit 096de2f83ebc ("benet: stricter vxlan offloading check in be_features_check") avoids hardware segmentation of non-VXLAN tunneled packets, or VXLAN packets having wrong destination port. So, it's safe to avoid flipping the above feature on addition/deletion of VXLAN tunnels.

2017-02-01be2net: fix initial MAC settingIvan Vecera
Recent commit 34393529163a ("be2net: fix MAC addr setting on privileged BE3 VFs") allows privileged BE3 VFs to set its MAC address during initialization. Although the initial MAC for such VFs is already programmed by parent PF the subsequent setting performed by VF is OK, but in certain cases (after fresh boot) this command in VF can fail. The MAC should be initialized only when: 1) no MAC is programmed (always except BE3 VFs during first init) 2) programmed MAC is different from requested (e.g. MAC is set when interface is down). In this case the initial MAC programmed by PF needs to be deleted. The adapter->dev_mac contains MAC address currently programmed in HW so it should be zeroed when the MAC is deleted from HW and should not be filled when MAC is set when interface is down in be_mac_addr_set() as no programming is performed in this case. Example of failure without the fix (immediately after fresh boot): # ip link set eth0 up <- eth0 is BE3 PF be2net 0000:01:00.0 eth0: Link is Up # echo 1 > /sys/class/net/eth0/device/sriov_numvfs <- Create 1 VF ... be2net 0000:01:04.0: Emulex OneConnect(be3): VF port 0 # ip link set eth8 up <- eth8 is created privileged VF be2net 0000:01:04.0: opcode 59-1 failed:status 1-76 RTNETLINK answers: Input/output error # echo 0 > /sys/class/net/eth0/device/sriov_numvfs <- Delete VF iommu: Removing device 0000:01:04.0 from group 33 ... # echo 1 > /sys/class/net/eth0/device/sriov_numvfs <- Create it again iommu: Removing device 0000:01:04.0 from group 33 ... # ip link set eth8 up be2net 0000:01:04.0 eth8: Link is Up Initialization is now OK. v2 - Corrected the comment and condition check suggested by Suresh & Harsha Fixes: 34393529163a ("be2net: fix MAC addr setting on privileged BE3 VFs") Cc: Sathya Perla <sathya.perla@broadcom.com> Cc: Ajit Khaparde <ajit.khaparde@broadcom.com> Cc: Sriharsha Basavapatna <sriharsha.basavapatna@broadcom.com> Cc: Somnath Kotur <somnath.kotur@broadcom.com> Signed-off-by: Ivan Vecera <cera@cera.cz> Acked-by: Sriharsha Basavapatna <sriharsha.basavapatna@broadcom.com> Signed-off-by: David S.

2017-01-16be2net: fix MAC addr setting on privileged BE3 VFsIvan Vecera
During interface opening MAC address stored in netdev->dev_addr is programmed in the HW with exception of BE3 VFs where the initial MAC is programmed by parent PF. This is OK when MAC address is not changed when an interfaces is down. In this case the requested MAC is stored to netdev->dev_addr and later is stored into HW during opening. But this is not done for all BE3 VFs so the NIC HW does not know anything about this change and all traffic is filtered. This is the case of bonding if fail_over_mac == 0 where the MACs of the slaves are changed while they are down. The be2net behavior is too restrictive because if a BE3 VF has the FILTMGMT privilege then it is able to modify its MAC without any restriction. To solve the described problem the driver should take care about these privileged BE3 VFs so the MAC is programmed during opening. And by contrast unpriviled BE3 VFs should not be allowed to change its MAC in any case.

2017-01-03benet: stricter vxlan offloading check in be_features_checkSabrina Dubroca
When VXLAN offloading is enabled, be_features_check() tries to check if an encapsulated packet is indeed a VXLAN packet. The check is not strict enough, and considers any UDP-encapsulated ethernet frame with a 8-byte tunnel header as being VXLAN. Unfortunately, both GENEVE and VXLAN-GPE have a 8-byte header, so they get through this check. Force the UDP destination port to be the one that has been offloaded to hardware. Without this, GENEVE-encapsulated packets can end up having an incorrect checksum when both a GENEVE and a VXLAN (offloaded) tunnel are configured.

All conflicts were simple overlapping changes except perhaps for the Thunder driver. That driver has a change_mtu method explicitly for sending a message to the hardware. If that fails it returns an error. Normally a driver doesn't need an ndo_change_mtu method becuase those are usually just range changes, which are now handled generically. But since this extra operation is needed in the Thunder driver, it has to stay. However, if the message send fails we have to restore the original MTU before the change because the entire call chain expects that if an error is thrown by ndo_change_mtu then the MTU did not change. Therefore code is added to nicvf_change_mtu to remember the original MTU, and to restore it upon nicvf_update_hw_max_frs() failue. Signed-off-by: David S. Miller <davem@davemloft.net>

There are also a few drivers that had no upper bounds checking, so they're getting a brand new ETH_MAX_MTU that is identical to IP_MAX_MTU, but accessible by includes all ethernet and ethernet-like drivers all have already. acenic: - min_mtu = 0, max_mtu = 9000 amazon/ena: - min_mtu = 128, max_mtu = adapter->max_mtu amd/xgbe: - min_mtu = 0, max_mtu = 9000 sb1250: - min_mtu = 0, max_mtu = 1518 cxgb3: - min_mtu = 81, max_mtu = 65535 cxgb4: - min_mtu = 81, max_mtu = 9600 cxgb4vf: - min_mtu = 81, max_mtu = 65535 benet: - min_mtu = 256, max_mtu = 9000 ibmveth: - min_mtu = 68, max_mtu = 65535 ibmvnic: - min_mtu = adapter->min_mtu, max_mtu = adapter->max_mtu - remove now redundant ibmvnic_change_mtu jme: - min_mtu = 1280, max_mtu = 9202 mv643xx_eth: - min_mtu = 64, max_mtu = 9500 mlxsw: - min_mtu = 0, max_mtu = 65535 - Basically bypassing the core checks, and instead relying on dynamic checks in the respective switch drivers' ndo_change_mtu functions ns83820: - min_mtu = 0 - remove redundant ns83820_change_mtu, only checked for mtu > 1500 netxen: - min_mtu = 0, max_mtu = 8000 (P2), max_mtu = 9600 (P3) qlge: - min_mtu = 1500, max_mtu = 9000 - driver only supports setting mtu to 1500 or 9000, so the core check only rules out < 1500 and > 9000, qlge_change_mtu still needs to check that the value is 1500 or 9000 qualcomm/emac: - min_mtu = 46, max_mtu = 9194 xilinx_axienet: - min_mtu = 64, max_mtu = 9000 Fixes: 61e84623ace3 ("net: centralize net_device min/max MTU checking") CC: netdev@vger.kernel.org CC: Jes Sorensen <jes@trained-monkey.org> CC: Netanel Belgazal <netanel@annapurnalabs.com> CC: Tom Lendacky <thomas.lendacky@amd.com> CC: Santosh Raspatur <santosh@chelsio.com> CC: Hariprasad S <hariprasad@chelsio.com> CC: Sathya Perla <sathya.perla@broadcom.com> CC: Ajit Khaparde <ajit.khaparde@broadcom.com> CC: Sriharsha Basavapatna <sriharsha.basavapatna@broadcom.com> CC: Somnath Kotur <somnath.kotur@broadcom.com> CC: Thomas Falcon <tlfalcon@linux.vnet.ibm.com> CC: John Allen <jallen@linux.vnet.ibm.com> CC: Guo-Fu Tseng <cooldavid@cooldavid.org> CC: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com> CC: Jiri Pirko <jiri@mellanox.com> CC: Ido Schimmel <idosch@mellanox.com> CC: Manish Chopra <manish.chopra@qlogic.com> CC: Sony Chacko <sony.chacko@qlogic.com> CC: Rajesh Borundia <rajesh.borundia@qlogic.com> CC: Timur Tabi <timur@codeaurora.org> CC: Anirudha Sarangi <anirudh@xilinx.com> CC: John Linn <John.Linn@xilinx.com> Signed-off-by: Jarod Wilson <jarod@redhat.com> Signed-off-by: David S.

2016-10-09be2net: NCSI FW section should be properly updated with ethtool for BE3Sriharsha Basavapatna
The driver has a check to ensure that NCSI FW section is updated only if the current FW version in the card supports it. This FW version check is done using memcmp() which obviously fails in some cases. Fix this by breaking up the version string into integer version components and comparing them.

2016-10-09be2net: Provide an alternate way to read pf_num for BEx chipsSriharsha Basavapatna
The driver gets the pf_num for Skyhawk and Lancer using GET_FUNC_CONFIG FW command. But since that command is not supported in BEx, we need to get it from some other command. Otherwise TPE recovery would fail since all NIC PFs would end up with a func num of 0. There's a pci function number field in the response of GET_CNTL_ATTRIBUTES command that can be read to get the same info for BEx adapters.

2016-09-24net: Update API for VF vlan protocol 802.1ad supportMoshe Shemesh
Introduce new rtnl UAPI that exposes a list of vlans per VF, giving the ability for user-space application to specify it for the VF, as an option to support 802.1ad. We adjusted IP Link tool to support this option. For future use cases, the new UAPI supports multiple vlans. For now we limit the list size to a single vlan in kernel. Add IFLA_VF_VLAN_LIST in addition to IFLA_VF_VLAN to keep backward compatibility with older versions of IP Link tool. Add a vlan protocol parameter to the ndo_set_vf_vlan callback. We kept 802.1Q as the drivers' default vlan protocol. Suitable ip link tool command examples: Set vf vlan protocol 802.1ad: ip link set eth0 vf 1 vlan 100 proto 802.1ad Set vf to VST (802.1Q) mode: ip link set eth0 vf 1 vlan 100 proto 802.1Q Or by omitting the new parameter ip link set eth0 vf 1 vlan 100 Signed-off-by: Moshe Shemesh <moshe@mellanox.com> Signed-off-by: Tariq Toukan <tariqt@mellanox.com> Signed-off-by: David S.

2016-09-07be2net: Fix mac address collision in some configurationsSuresh Reddy
If the device mac address is updated using ndo_set_mac_address(), while the same mac address is already programmed, the driver does not detect this condition if its netdev->dev_addr has been changed. The driver tries to add the same mac address resulting in mac address collision error. This has been observed in bonding mode-5 configuration. To fix this, store the mac address configured in HW in the adapter structure. Use this to compare against the new address being updated to avoid collision.

2016-09-07be2net: Avoid redundant addition of mac address in HWSuresh Reddy
If a mac address is added to the uc_list and later the same mac address is added via ndo_set_mac_address() or vice versa, the driver does not detect this condition and tries to add it again. This results in a mac address collision error when the FW rejects it. Fix this by checking if the given mac address is present in uc_list while setting the device mac address and vice versa. Similarly skip deletion if the address is still in use in the other form.
