2013-06-05bnx2x: Fix bridged GSO for 57710/57711 chipsYuval Mintz1-2/+1
It was recently found out that GSO on 57710/57711 was broken, due to packets being sent without a valid IP checksum. Commit 057cf65 "bnx2x: Fix GSO for 57710/57711 chips" partially fixed this issue, but failed to set the correct IP checksum when receiving GSO packets via bridges, as such packets enter bnx2x_tx_split() and the FW flags needed to calculate IP checksum were erroneously set in the incorrect buffer descriptor. This patch re-enables GSO in said scenario for 57710/57711 chips.

2013-05-24bnx2x: Wait for MCP validity during AERYuval Mintz1-15/+4
During PCIe advanced error recovery, the secondary bus reset will cause FW to reset; This will cause the shared memory between it and the driver to be invalidated. During the driver's recovery flow, the driver should not make any assumption on the validity of that memory and instead re-initialize it.

2013-05-24bnx2x: Link-flap avoidance in switch dependent modeDmitry Kravkov4-5/+28
As part of the previous unload flow, probed devices will reset the chip in order to clean the remains of the UNDI driver. As a result, it's possible for the FW to toggle the link. This toggling can prove fatal, as long periods without link can cause the filesystem mount to fail as the storage protocol timeouts. This has been observed against particular switches with long link re-establishment time. This patch informs FW during the reset period that the link should not be toggled - the FW will keep it alive until some interface will load and claim the link as its own.

This behaviour needs to be revised for 57710/57711 chips - when using GSO, if the driver will not set the IP checksum flag then packets will be transmitted by the chip without a valid IP checksum, resulting in a drop of all such packets on the receiver-side.

2013-04-25bnx2x: Prevent NULL pointer dereference in kdumpYuval Mintz3-23/+39
In scenarios in which a previous driver was removed without proper cleanup (e.g., kdump), it is possible for the chip to generate an interrupt without any apparent reason once interrupts are requested. Due to an erroneous initialization of resources, some of the bnx2x structs which are required for interrupt handling are initialized only after an interface's interrupt is requested from the OS. As a result, once such a spurious interrupt occurs, it will cause a NULL pointer dereference - the driver will access those structs in its interrupt handling routine. This patch change the interrupt request scheme so that bnx2x would only request interrupts from the kernel after it has finished initializing all the inner structs required for interrupt handling.

The driver's PCI error handlers will in turn restore the PCI configuration space values by calling `pci_restore_state'.

2013-04-25bnx2x: prevent GRO false checksum claimsYuval Mintz1-5/+11
This patch introduces a more robust error handling flow in case of incorrect behaviour by the FW when passing on GRO aggregations. Although this should never happen (i.e., this is merely a theoretical fix), if the bnx2x driver was to receive a GRO from FW with protocol other than IPv4/IPv6, the driver would falsely claim to have performed partial checksum and set various incorrect fields in the skb header. Current behaviour of the bnx2x driver (i.e., print an error) is insufficient. This patch remedies this by simply preventing the false claims.

The be2net driver had a bug fix in 'net' that overlapped with the VLAN interface changes by Patrick McHardy in net-next. An IGB conflict existed because in 'net' the build_skb() support was reverted, and in 'net-next' there was a comment style fix within that code. Several batman-adv conflicts were resolved by making sure that all calls to batadv_is_my_mac() are changed to have a new bat_priv first argument. Eric Dumazet's TS ECR fix in TCP in 'net' conflicted with the F-RTO rewrite in 'net-next', mostly overlapping changes. Thanks to Stephen Rothwell and Antonio Quartulli for help with several of these merge resolutions. Signed-off-by: David S. Miller <davem@davemloft.net>

2013-04-19net: vlan: add protocol argument to packet tagging functionsPatrick McHardy1-2/+2
Add a protocol argument to the VLAN packet tagging functions. In case of HW tagging, we need that protocol available in the ndo_start_xmit functions, so it is stored in a new field in the skb. The new field fits into a hole (on 64 bit) and doesn't increase the sks's size. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

2013-04-18bnx2x: Prevent UNDI FW illegal host accessDmitry Kravkov1-0/+4
When loading after UNDI (e.g., Boot from SAN) the UNDI does not gracefully yield its resources; The bnx2x driver handles that release itself. During the manipulation required to release those resources, it's possible for the UNDI to try and write to memory regions which are no longer accessible, causing the PCI bus to prevent further writes from the chip. This would in turn cause DMAE timeouts later on in the driver, as the driver will be unable to use the chip's DMA engines. This patch prevents the chip from actually writing through the PCI bus in said scenario, thus allowing the release without the unfortunate by-product.

2013-04-10bnx2x: Prevent null pointer dereference in AFEX modeYuval Mintz1-1/+2
The cnic module is responsible for initializing various bnx2x structs via callbacks provided by the bnx2x module. One such struct is the queue object for the FCoE queue. If a device is working in AFEX mode and its configuration allows FCoE yet the cnic module is not loaded, it's very likely a null pointer dereference will occur, as the bnx2x will erroneously access the FCoE's queue object. Prevent said access until cnic properly registers itself.
