2017-12-01net: ethernet: ti: ale: optimize ale entry mask bits configuartionGrygorii Strashko1-10/+3
The ale->params.ale_ports parameter can be used to deriver values for all ale entry mask bits: port_mask_bits, port_mask_bits, port_num_bits. Hence, calculate above values and drop all hardcoded values. For port_num_bits calcualtion use order_base_2() API. Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: David S.

ALE is enabled from cpsw_ale_start() now, but disabled only from cpsw_ale_destroy() which introduces inconsitance as cpsw_ale_start() is called when netif[s] is opened, but cpsw_ale_destroy() is called when driver is removed.

2017-12-01net: phy: core: use genphy version of callbacks read_status and config_aneg ↵Heiner Kallweit1-1/+4
per default read_status and config_aneg are the only mandatory callbacks and most of the time the generic implementation is used by drivers. So make the core fall back to the generic version if a driver doesn't implement the respective callback. Also currently the core doesn't seem to verify that drivers implement the mandatory calls. If a driver doesn't do so we'd just get a NPE. With this patch this potential issue doesn't exit any longer.

2017-11-30vmxnet3: increase default rx ring sizesShrikrishna Khare1-4/+4
There are several reasons for increasing the receive ring sizes: 1. The original ring size of 256 was chosen about 10 years ago when vmxnet3 was first created. At that time, 10Gbps Ethernet was not prevalent and servers were dominated by 1Gbps Ethernet. Now 10Gbps is common place, and higher bandwidth links -- 25Gbps, 40Gbps, 50Gbps -- are starting to appear. 256 Rx ring entries are simply not enough to keep up with higher link speed when there is a burst of network frames coming from these high speed links. Even with full MTU size frames, they are gone in a short time. It is also more common to have a mix of frame sizes, and more likely bi-modal distribution of frame sizes so the average frame size is not close to full MTU. If we consider average frame size of 800B, 1024 frames that come in a burst takes ~0.65 ms to arrive at 10Gbps. With 256 entires, it takes ~0.16 ms to arrive at 10Gbps. At 25Gbps or 40Gbps, this time is reduced accordingly. 2. On a hypervisor where there are many VMs and CPU is over committed, i.e. the number of VCPUs is more than the number of VCPUs, each PCPU is in effect time shared between multiple VMs/VCPUs. The time granularity at which this multiplexing occurs is typically coarser than between processes on a guest OS. Trying to time slice more finely is not efficient, for example, if memory cache is barely warmed up when switching from one VM to another occurs. This CPU overcommit adds delay to when the driver in a VM can service incoming packets. Whether CPU is over committed really depends on customer workloads. For certain situations, it is very common. For example, workloads of desktop VMs and product testing setups. Consolidation and sharing is what drives efficiency of a customer setup for such workloads. In these situations, the raw network bandwidth may not be very high, but the delays between when a VM is running or not running can also be relatively long.

2017-11-28mlxsw: spectrum_router: Update nexthop RIF on updatePetr Machata1-7/+21
The function mlxsw_sp_nexthop_rif_update() walks the list of nexthops associated with a RIF, and updates the corresponding entries in the switch. It is used in particular when a tunnel underlay netdevice moves to a different VRF, and all the nexthops are migrated over to a new RIF. The problem is that each nexthop holds a reference to its RIF, and that is not updated. So after the old RIF is gone, further activity on these nexthops (such as downing the underlay netdevice) dereferences a dangling pointer. Fix the issue by updating rif of impacted nexthops before calling mlxsw_sp_nexthop_rif_update().

Some tunnels that are offloadable on their own can nonetheless be demoted to slow path if their local address is in conflict with that of another tunnel. When a route is formed for such a tunnel, mlxsw_sp_nexthop_ipip_init() fails to find the corresponding IPIP entry, and that triggers a FIB abort.

2017-11-28mlxsw: spectrum_router: Demote tunnels on VRF migrationPetr Machata1-0/+18
The mlxsw driver currently doesn't offload GRE tunnels if they have the same local address and use the same underlay VRF. When such a situation arises, the tunnels in conflict are demoted to slow path. However, the current code only verifies this condition on tunnel creation and tunnel change, not when a tunnel is moved to a different VRF. When the tunnel has no bound device, underlay and overlay are the same. Thus moving a tunnel moves the underlay as well, and that can cause local address conflict. So modify mlxsw_sp_netdevice_ipip_ol_vrf_event() to check if there are any conflicting tunnels, and demote them if yes.

When a new local route is added, an IPIP entry is looked up to determine whether the route should be offloaded as a tunnel decap or as a trap. That decision should take into account whether the tunnel netdevice in question is actually IFF_UP, and only install a decap offload if it is.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-queue Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2017-11-27 This series contains updates to e1000, e1000e and i40e. Gustavo A. R. Silva fixes a sizeof() issue where we were taking the size of the pointer (which is always the size of the pointer). Sasha does a follow up fix to a previous fix for buffer overrun, to resolve community feedback from David Laight and the use of magic numbers. Amritha fixes the reporting of error codes for when adding a cloud filter fails. Ahmad Fatoum brushes the dust off the e1000 driver to fix a code comment and debug message which was incorrect about what the code was really doing. ==================== Signed-off-by: David S.

2017-11-27i40e: Fix reporting incorrect error codesAmritha Nambiar1-1/+0
Adding cloud filters could fail for a number of reasons, unsupported filter fields for example, which fails during validation of fields itself. This will not result in admin command errors and converting the admin queue status to posix error code using i40e_aq_rc_to_posix would result in incorrect error values. If the failure was due to AQ error itself, reporting that correctly is handled in the inner function.

2017-11-27e1000e: fix the use of magic numbers for buffer overrun issueSasha Neftin2-4/+8
This is a follow on to commit b10effb92e27 ("fix buffer overrun while the I219 is processing DMA transactions") to address David Laights concerns about the use of "magic" numbers. So define masks as well as add additional code comments to give a better understanding of what needs to be done to avoid a buffer overrun.

2017-11-27i40e/virtchnl: fix application of sizeof to pointerGustavo A R Silva1-1/+1
sizeof when applied to a pointer typed expression gives the size of the pointer. The proper fix in this particular case is to code sizeof(*vfres) instead of sizeof(vfres). This issue was detected with the help of Coccinelle.

2017-11-27Rename superblock flags (MS_xyz -> SB_xyz)Linus Torvalds3-11/+11
This is a pure automated search-and-replace of the internal kernel superblock flags. The s_flags are now called SB_*, with the names and the values for the moment mirroring the MS_* flags that they're equivalent to. Note how the MS_xyz flags are the ones passed to the mount system call, while the SB_xyz flags are what we then use in sb->s_flags. The script to do this was: # places to look in; re security/*: it generally should *not* be # touched (that stuff parses mount(2) arguments directly), but # there are two places where we really deal with superblock flags.
