* net: aquantia: vlan unicast address list correct handlingIgor Russkikh2018-07-067-36/+36
| | | | | | | | | | | | | | | | | | Setting up macvlan/macvtap networks over atlantic NIC results in no traffic over these networks because ndo_set_rx_mode did not listed UC MACs as registered in unicast filter. Here we fix that taking into account maximum number of UC filters supported by hardware. If more than MAX addresses were registered, we just enable promisc and/or allmulti to pass the traffic in. We also remove MULTICAST_ADDRESS_MAX constant from aq_cfg since thats not a configurable parameter at all. Fixes: b21f502 ("net:ethernet:aquantia: Fix for multicast filter handling.")

* net: aquantia: fix unsigned numvecs comparison with less than zeroColin Ian King2018-06-091-6/+5
| | | | | | | | | | | | | | | | | | From: Colin Ian King <colin.king@canonical.com> This was originally mistakenly submitted to net-next. Resubmitting to net. The comparison of numvecs < 0 is always false because numvecs is a u32 and hence the error return from a failed call to pci_alloc_irq_vectores is never detected. Fix this by using the signed int ret to handle the error return and assign numvecs to err.

* net: aquantia: Limit number of vectors to actually allocated irqsIgor Russkikh2018-05-083-10/+12
| | | | | | | | | | | | | | | | Driver should use pci_alloc_irq_vectors return value to correct number of allocated vectors and napi instances. Otherwise it'll panic later in pci_irq_vector. Driver also should allow more than one MSI vectors to be allocated. Error return path from pci_alloc_irq_vectors is also fixed to revert resources in a correct sequence when error happens.

* net: aquantia: oops when shutdown on already stopped deviceIgor Russkikh2018-04-111-3/+5
| | | | | | | | | | | | | | | In case netdev is closed at the moment of pci shutdown, aq_nic_stop gets called second time. napi_disable in that case hangs indefinitely. In other case, if device was never opened at all, we get oops because of null pointer access. We should invoke aq_nic_stop conditionally, only if device is running at the moment of shutdown.

* net: aquantia: Regression on reset with 1.x firmwareIgor Russkikh2018-04-111-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | On ASUS XG-C100C with 1.5.44 firmware a special mode called "dirty wake" is active. With this mode when motherboard gets powered (but no poweron happens yet), NIC automatically enables powersave link and watches for WOL packet. This normally allows to powerup the PC after AC power failures. Not all motherboards or bios settings gives power to PCI slots, so this mode is not enabled on all the hardware. 4.16 linux driver introduced full hardware reset sequence This is required since before that we had no NIC hardware reset implemented and there were side effects of "not clean start". But this full reset is incompatible with "dirty wake" WOL feature it keeps the PHY link in a special mode forever. As a consequence, driver sees no link and no traffic. To fix this we forcibly change FW state to idle state before doing the full reset. This makes FW to restore link state.

For the mac80211 stuff, these were fortunately just parallel adds. Trivially resolved. In drivers/net/phy/phy.c we had a bug fix in 'net' that moved the function phy_disable_interrupts() earlier in the file, whilst in 'net-next' the phy_error() call from this function was removed. In net/ipv4/xfrm4_policy.c, David Ahern's changes to remove the 'rt_table_id' member of rtable collided with a bug fix in 'net' that added a new struct member "rt_mtu_locked" which needs to be copied over here. The mlxsw driver conflict consisted of net-next separating the span code and definitions into separate files, whilst a 'net' bug fix made some changes to that moved code. The mlx5 infiniband conflict resolution was quite non-trivial, the RDMA tree's merge commit was used as a guide here, and here are their notes: ==================== Due to bug fixes found by the syzkaller bot and taken into the for-rc branch after development for the 4.17 merge window had already started being taken into the for-next branch, there were fairly non-trivial merge issues that would need to be resolved between the for-rc branch and the for-next branch. This merge resolves those conflicts and provides a unified base upon which ongoing development for 4.17 can be based. Conflicts: drivers/infiniband/hw/mlx5/main.c - Commit 42cea83f9524 (IB/mlx5: Fix cleanup order on unload) added to for-rc and commit b5ca15ad7e61 (IB/mlx5: Add proper representors support) add as part of the devel cycle both needed to modify the init/de-init functions used by mlx5. To support the new representors, the new functions added by the cleanup patch needed to be made non-static, and the init/de-init list added by the representors patch needed to be modified to match the init/de-init list changes made by the cleanup patch. Updates: drivers/infiniband/hw/mlx5/mlx5_ib.h - Update function prototypes added by representors patch to reflect new function names as changed by cleanup patch drivers/infiniband/hw/mlx5/ib_rep.c - Update init/de-init stage list to match new order from cleanup patch ==================== Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | We should close link and all NIC operations during shutdown. On some systems graceful reboot never closes NIC interface on its own, but only indicates pci device shutdown. Without explicit handler, NIC rx rings continued to transfer DMA data into prepared buffers while CPU rebooted already. That caused memory corruptions on soft reboot.
