2017-03-07bnx2x: add missing configuration of VF VLAN filtersMichal Schmidt

2017-03-07bnx2x: prevent crash when accessing PTP with interface downMichal Schmidt
It is possible to crash the kernel by accessing a PTP device while its associated bnx2x interface is down. Before the interface is brought up, the timecounter is not initialized, so accessing it results in NULL dereference. Fix it by checking if the interface is up. Use -ENETDOWN as the error code when the interface is down. -EFAULT in bnx2x_ptp_adjfreq() did not seem right. Tested using phc_ctl get/set/adj/freq commands.

2016-12-05bnx2x: Correct ringparam estimate when DOWNMintz, Yuval
Until interface is up [and assuming ringparams weren't explicitly configured] when queried for the size of its rings bnx2x would claim they're the maximal size by default. That is incorrect as by default the maximal number of buffers would be equally divided between the various rx rings. This prevents the user from actually setting the number of elements on each rx ring to be of maximal size prior to transitioning the interface into up state. To fix this, make a rough estimation about the number of buffers. It wouldn't always be accurate, but it would be much better than current estimation and would allow users to increase number of buffers during early initialization of the interface.

2016-12-05net: bnx2x: fix improper return valuePan Bian
Macro BNX2X_ALLOC_AND_SET(arr, lbl, func) calls kmalloc() to allocate memory, and jumps to label "lbl" if the allocation fails. Label "lbl" first cleans memory and then returns variable rc. Before calling the macro, the value of variable rc is 0. Because 0 means no error, the callers of bnx2x_init_firmware() may be misled.

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.

2016-09-01bnx2x: don't reset chip on cleanup if PCI function is offlineGuilherme G. Piccoli
When PCI error is detected, in some architectures (like PowerPC) a slot reset is performed - the driver's error handlers are in charge of "disable" device before the reset, and re-enable it after a successful slot reset. There are two cases though that another path is taken on the code: if the slot reset is not successful or if too many errors already happened in the specific adapter (meaning that possibly the device is experiencing a HW failure that slot reset is not able to solve), the core PCI error mechanism (called EEH in PowerPC) will remove the adapter from the system, since it will consider this as a permanent failure on device. In this case, a path is taken that leads to bnx2x_chip_cleanup() calling bnx2x_reset_hw(), which then tries to perform a HW reset on chip. This reset won't succeed since the HW is in a fault state, which can be seen by multiple messages on kernel log like below: bnx2x: [bnx2x_issue_dmae_with_comp:552(eth1)]DMAE timeout! bnx2x: [bnx2x_write_dmae:600(eth1)]DMAE returned failure -1 After some time, the PCI error mechanism gives up on waiting the driver's correct removal procedure and forcibly remove the adapter from the system. We can see soft lockup while core PCI error mechanism is waiting for driver to accomplish the right removal process. This patch adds a verification to avoid a chip reset whenever the function is in PCI error state - since this case is only reached when we have a device being removed because of a permanent failure, the HW chip reset is not expected to work fine neither is necessary. Also, as a minor improvement in error path, we avoid the MCP information dump in case of non-recoverable PCI error (when adapter is about to be removed), since it will certainly fail.

2016-08-24bnx2x: Don't flush multicast MACsYuval Mintz
When ndo_set_rx_mode() is called for bnx2x, as part of process of configuring the new MAC address filters [both unicast & multicast] driver begins by flushing the existing configuration and then iterating over the network device's list of addresses and configures those instead. This has the side-effect of creating a short gap where traffic wouldn't be properly classified, as no filters are configured in HW. While for unicasts this is rather insignificant [as unicast MACs don't frequently change while interface is actually running], for multicast traffic it does pose an issue as there are multicast-based networks where new multicast groups would constantly be removed and added. This patch tries to remedy this [at least for the newer adapters] - Instead of flushing & reconfiguring all existing multicast filters, the driver would instead create the approximate hash match that would result from the required filters. It would then compare it against the currently configured approximate hash match, and only add and remove the delta between those.

Fix this peculiar behavior in the following way: - Accept requests to add/kill VID regardless of the device state. Maintain the requested list of VIDs in the bp->vlan_reg list. - If the device is up, try to configure the VID list into the hardware. If we run out of VLAN credits or encounter a failure configuring an entry, fall back to accepting all VLANs. If we successfully configure all entries from the list, turn the fallback off. - Use the same code for reconfiguring VLANs during NIC load.

bnx2x crashes during the initialization of the 8021q module on ppc64. The bug is a missing conversion from le32 in bnx2x_handle_classification_eqe() when obtaining the cid value from struct eth_event_data. The fields in struct eth_event_data should all be declared as little-endian and conversions added where missing. Signed-off-by: Michal Schmidt <mschmidt@redhat.com> Signed-off-by: David S.

2016-02-24bnx2x: add a separate GENEVE Kconfig symbolArnd Bergmann
When CONFIG_GENEVE is built as a loadable module, and bnx2x is built-in, we get this link error: drivers/net/built-in.o: In function `bnx2x_open': :(.text+0x33322): undefined reference to `geneve_get_rx_port' drivers/net/built-in.o: In function `bnx2x_sp_rtnl_task': :(.text+0x3e632): undefined reference to `geneve_get_rx_port' This avoids the problem by adding a separate Kconfig symbol named CONFIG_BNX2X_GENEVE that is only enabled when the code is reachable from the driver. This is the same trick that BNX2X does for VXLAN support, and is similar to how I40E handles both.
