| * | | | mlxsw: spectrum_router: Add batch neighbour deletionIdo Schimmel2017-11-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In commit 4a3c67a6e7cd ("mlxsw: spectrum_router: Don't batch neighbour deletion") I removed the support for batch deletion of neighbours on a router interface (RIF) since at that time the firmware did not support it for IPv6 neighbours. This is now supported by the version enforced by the driver, so there is no reason to delete neighbours one by one anymore.

In the function bnx2x_sp_rtnl_task, bnx2x_nic_unload and bnx2x_nic_load are executed to shutdown and open NIC. In the function bnx2x_nic_load, bnx2x_alloc_mem allocates dma failure. The message "bnx2x: [bnx2x_alloc_mem:8399(em4)]Can't allocate memory" pops out. The variable slowpath is set to NULL. When shutdown the NIC, the function bnx2x_nic_unload is called. In the function bnx2x_nic_unload, the following functions are executed. bnx2x_chip_cleanup bnx2x_set_storm_rx_mode bnx2x_set_q_rx_mode bnx2x_set_q_rx_mode bnx2x_config_rx_mode bnx2x_set_rx_mode_e2 In the function bnx2x_set_rx_mode_e2, the variable slowpath is operated. Then the crash occurs. To fix this crash, the variable slowpath is checked. And in the function bnx2x_sp_rtnl_task, after dma memory allocation fails, another shutdown and open NIC is executed.

I moved the allocation to the probe() function and made it managed. >From the Colin's email: While running static analysis on linux-next with CoverityScan I found 3 double free errors in the Cavium thunder driver. The issue occurs on the err_disable_device: label of function nic_probe when nic_free_lmacmem(nic) is called and a double free occurs on nic->duplex, nic->link and nic->speed. This occurs when nic_init_hw() fails: /* Initialize hardware */ err = nic_init_hw(nic); if (err) goto err_release_regions; nic_init_hw() calls nic_get_hw_info() and this calls nic_free_lmacmem() if any of the allocations fail. This free'ing occurs again by the call to nic_free_lmacmem() on the err_release_regions exit path in nic_probe().

Instead of using CHECKSUM_COMPLETE offload for packets with first ethertype of IPv4/6, use it for packets with last ethertype of IPv4/6 to cover the former cases as well. The checksum field present in the CQE is calculated from the IP header until the end of the packet. When the first ethertype is different than IPv4/6 (for ex. 802.1Q VLAN) a checksum of the VLAN header/s should be added. The small header/s checksum calculation will allow us to use CHECKSUM_COMPLETE instead of CHECKSUM_UNNECESSARY.
