2021-06-30be2net: Fix an error handling path in 'be_probe()'Christophe JAILLET
[ Upstream commit c19c8c0e666f9259e2fc4d2fa4b9ff8e3b40ee5d ] If an error occurs after a 'pci_enable_pcie_error_reporting()' call, it must be undone by a corresponding 'pci_disable_pcie_error_reporting()' call, as already done in the remove function.

2020-05-10be2net: Don't leak iomapped memory on removal.Douglas Miller
commit a69bf3c5b49ef488970c74e26ba0ec12f08491c2 upstream. The adapter->pcicfg resource is either mapped via pci_iomap() or derived from adapter->db. During be_remove() this resource was ignored and so could remain mapped after remove. Add a flag to track whether adapter->pcicfg was mapped or not, then use that flag in be_unmap_pci_bars() to unmap if required.

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().

[ Upstream commit 718f4a2537089ea41903bf357071306163bc7c04 ] Number of Rx queues used for flow hashing returned by the driver is incorrect and this bug prevents user to use the last Rx queue in indirection table.

2015-12-28RDMA/be2net: Remove open and close entry pointsDevesh Sharma
Recently Dough Ledford reported a deadlock happening between ocrdma-load sequence and NetworkManager service issueing "open" on be2net interface. The deadlock happens when any be2net hook (e.g. open/close) is called in parallel to insmod ocrdma.ko. A. be2net is sending administrative open/close event to ocrdma holding device_list_mutex. It does this from ndo_open/ndo_stop hooks of be2net. So sequence of locks is rtnl_lock---> device_list lock B. When new ocrdma roce device gets registered, infiniband stack now takes rtnl_lock in ib_register_device() in GID initialization routines. So sequence of locks in this path is device_list lock ---> rtnl_lock. This improper locking sequence causes deadlock. In order to resolve the above deadlock condition, ocrdma intorduced a patch to stop listening to administrative open/close events generated from be2net driver. It now depends on link-state-change async-event generated from CNA. This change leaves behind dead code which used to generate administrative open/close events. This patch cleans-up all that dead code from be2net.

2015-10-13be2net: remove vlan promisc capability from VF's profile descriptorsKalesh AP
The commit 435452aa8847 ("Prevent VFs from enabling VLAN promiscuous mode") fixed the PF driver to not include the VLAN promisc capability while provisioning the interface for a VF. But the fix did not remove this capability from the profile descriptor of the VF. This causes the VF driver to request this capability when it tries to create it's interface at probe time. This could potentailly cause the VF probe to fail if the FW enforces strict checking of the flags based on what was provisoned by the PF. This strict checking is not being done by FW currently but will be fixed in a future version. This patch fixes this issue by updating the VF's profile descriptor so that they match the interface capability flags provisioned by the PF.

2015-10-13be2net: set pci_func_num while issuing GET_PROFILE_CONFIG cmdSomnath Kotur
The FW requires the pf_num field in the cmd hdr to be set for it to return the specific function's descriptors in the GET_PROFILE_CONFIG cmd. If not set, the FW returns the descriptors of all the functions on the device. If the first descriptor is not what is being queried for, the driver will read wrong data. This patch fixes this issue by using the GET_CNTL_ATTRIB cmd to query the real pci_func_num of a function and then uses it in the GET_PROFILE_CONFIG cmd.

2015-09-05be2net: Revert "make the RX_FILTER command asynchronous" commitSathya Perla
The be_cmd_rx_filter() routine sends a non-embedded cmd to the FW and used a pre-allocated dma memory to hold the cmd payload. This worked fine when this cmd was synchronous. This cmd was changed to asynchronous mode by the commit 8af65c2f4("make the RX_FILTER command asynchronous"). So now when there are two quick invocations of this cmd, the 2nd request may end up overwriting the first request, causing FW cmd corruption. This patch reverts the offending commit and hence fixes the regression.

2015-08-17be2net: avoid vxlan offloading on multichannel configsIvan Vecera
VxLAN offloading is not functional if the NIC is running in multichannel mode (UMC, FLEX-10, VNIC...). Enabling this additionally kills whole connectivity through the NIC and the device needs to be down and up to restore it. The firmware should take care about it and does not allow the conversion of interface to tunnel type (be_cmd_manage_iface) or should support VxLAN offloading if multichannel config is enabled. I have tested this on the latest available firmware (10.6.144.21).

2015-07-10be2net: make SET_LOOPBACK_MODE cmd asynchrounousSuresh Reddy
The SET_LOOPBACK_MODE command is always issued from ethtool only in a process context. So, while waiting for the cmd to complete, the driver can sleep instead of holding spin_lock_bh() on the mcc_lock. This is done by calling be_mcc_notify() instead of be_mcc_notify_wait() (that returns only after the cmd completes while the MCCQ is locked).

2015-07-10be2net: make the RX_FILTER command asynchronousSuresh Reddy
This fix makes the RX_FILTER cmd asynchronous, i.e., the caller issues this cmd and doesn't wait for a completion from the FW. If the FW/adapter is in an error state, this change helps in not holding up the rtnl_lock and keeping bottom halves disabled while the driver timesout waiting for a response from the FW.

2015-06-23switchdev; add VLAN support for port's bridge_getlinkScott Feldman
One more missing piece of the puzzle. Add vlan dump support to switchdev port's bridge_getlink. iproute2 "bridge vlan show" cmd already knows how to show the vlans installed on the bridge and the device , but (until now) no one implemented the port vlan part of the netlink PF_BRIDGE:RTM_GETLINK msg. Before this patch, "bridge vlan show": $ bridge -c vlan show port vlan ids sw1p1 30-34 << bridge side vlans 57 sw1p1 << device side vlans (missing) sw1p2 57 sw1p2 sw1p3 sw1p4 br0 None (When the port is bridged, the output repeats the vlan list for the vlans on the bridge side of the port and the vlans on the device side of the port. The listing above show no vlans for the device side even though they are installed). After this patch: $ bridge -c vlan show port vlan ids sw1p1 30-34 << bridge side vlan 57 sw1p1 30-34 << device side vlans 57 3840 PVID sw1p2 57 sw1p2 57 3840 PVID sw1p3 3842 PVID sw1p4 3843 PVID br0 None I re-used ndo_dflt_bridge_getlink to add vlan fill call-back func. switchdev support adds an obj dump for VLAN objects, using the same call-back scheme as FDB dump.

2015-06-23drivers/net: remove all references to obsolete Ethernet-HOWTOPaul Gortmaker
This howto made sense in the 1990s when users had to manually configure ISA cards with jumpers or vendor utilities, but with the implementation of PCI it became increasingly less and less relevant, to the point where it has been well over a decade since I last updated it. And there is no value in anyone else taking over updating it either. However the references to it continue to spread as boiler plate text from one Kconfig file into the next. We are not doing end users any favours by pointing them at this old document, so lets kill it with fire, once and for all, to hopefully stop any further spread. No code is changed in this commit, just Kconfig help text. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com> Signed-off-by: David S. Miller <davem@davemloft.net>

There are several places in the driver (all in control paths) where coherent dma memory is being allocated using either dma_alloc_coherent() or the deprecated pci_alloc_consistent().

2015-05-28cpumask_set_cpu_local_first => cpumask_local_spread, lamentRusty Russell
da91309e0a7e (cpumask: Utility function to set n'th cpu...) created a genuinely weird function. I never saw it before, it went through DaveM. (He only does this to make us other maintainers feel better about our own mistakes.) cpumask_set_cpu_local_first's purpose is say "I need to spread things across N online cpus, choose the ones on this numa node first"; you call it in a loop. It can fail. One of the two callers ignores this, the other aborts and fails the device open. It can fail in two ways: allocating the off-stack cpumask, or through a convoluted codepath which AFAICT can only occur if cpu_online_mask changes. Which shouldn't happen, because if cpu_online_mask can change while you call this, it could return a now-offline cpu anyway. It contains a nonsensical test "!cpumask_of_node(numa_node)". This was drawn to my attention by Geert, who said this causes a warning on Sparc. It sets a single bit in a cpumask instead of returning a cpu number, because that's what the callers want. It could be made more efficient by passing the previous cpu rather than an index, but that would be more invasive to the callers.

2015-05-19be2net: make hwmon interface optionalArnd Bergmann
The hwmon interface in the be2net driver causes a link error when be2net is built-in while the hwmon subsystem is a loadable module: drivers/built-in.o: In function `be_probe': drivers/net/ethernet/emulex/benet/be_main.c:5761: undefined reference to `devm_hwmon_device_register_with_groups' This adds a new Kconfig symbol, following the example of multiple other drivers that have the same problem. The new CONFIG_BE2NET_HWMON will not be available when (BE2NET=y && HWMON=m) to avoid this problem. We have to also mark be_hwmon_show_temp as 'static' to ensure the compiler can optimize out all the unused code.

2015-05-14be2net: Support for OS2BMC.Venkata Duvvuru
OS2BMC feature will allow the server to communicate with the on-board BMC/idrac (Baseboard Management Controller) over the LOM via standard Ethernet. When OS2BMC feature is enabled, the LOM will filter traffic coming from the host. If the destination MAC address matches the iDRAC MAC address, it will forward the packet to the NC-SI side band interface for iDRAC processing. Otherwise, it would send it out on the wire to the external network. Broadcast and multicast packets are sent on the side-band NC-SI channel and on the wire as well. Some of the packet filters are not supported in the NIC and hence driver will identify such packets and will hint the NIC to send those packets to the BMC. This is done by duplicating packets on the management ring. Packets are sent to the management ring, by setting mgmt bit in the wrb header. The NIC will forward the packets on the management ring to the BMC through the side-band NC-SI channel.
