2017-02-10NET: mkiss: Fix panicRalf Baechle
If a USB-to-serial adapter is unplugged, the driver re-initializes, with dev->hard_header_len and dev->addr_len set to zero, instead of the correct values. If then a packet is sent through the half-dead interface, the kernel will panic due to running out of headroom in the skb when pushing for the AX.25 headers resulting in this panic: [<c0595468>] (skb_panic) from [<c0401f70>] (skb_push+0x4c/0x50) [<c0401f70>] (skb_push) from [<bf0bdad4>] (ax25_hard_header+0x34/0xf4 [ax25]) [<bf0bdad4>] (ax25_hard_header [ax25]) from [<bf0d05d4>] (ax_header+0x38/0x40 [mkiss]) [<bf0d05d4>] (ax_header [mkiss]) from [<c041b584>] (neigh_compat_output+0x8c/0xd8) [<c041b584>] (neigh_compat_output) from [<c043e7a8>] (ip_finish_output+0x2a0/0x914) [<c043e7a8>] (ip_finish_output) from [<c043f948>] (ip_output+0xd8/0xf0) [<c043f948>] (ip_output) from [<c043f04c>] (ip_local_out_sk+0x44/0x48) This patch makes mkiss behave like the 6pack driver. 6pack does not panic. In 6pack.c sp_setup() (same function name here) the values for dev->hard_header_len and dev->addr_len are set to the same values as in my mkiss patch.

2017-02-10mlxsw: spectrum_router: Add support for route appendIdo Schimmel
When a new route is appended, it's placed after existing routes sharing the same parameters (prefix, length, table ID, TOS and priority). While the device supports only one route with the same prefix and length in a single table, it's important to correctly place the appended route in the driver's cache, as when a route is deleted the next one is programmed into the device. Following the reception of an ENTRY_APPEND notification, resolve the FIB node corresponding to the prefix and length and correctly place the new entry in its entry list.

2017-02-10mlxsw: spectrum_router: Correctly handle identical routesIdo Schimmel
In the device, routes are indexed in a routing table based on the prefix and its length. This is in contrast to the kernel's FIB where several FIB aliases can exist with these parameters being identical. In such cases, the routes will be sorted by table ID (LOCAL first, then MAIN), TOS and finally priority (metric). During lookup, these routes will be evaluated in order. In case the packet's TOS field is non-zero and a FIB alias with a matching TOS is found, then it's selected. Otherwise, the lookup defaults to the route with TOS 0 (if it exists). However, if the requested scope is narrower than the one found, then the lookup continues. To best reflect the kernel's datapath we should take the above into account. Given a prefix and its length, the reflected route will always be the first one in the FIB alias list. However, if the route has a non-zero TOS then its action will be converted to trap instead of forward, since we currently don't support TOS-based routing. If this turns out to be a real issue, we can add support for that using policy-based switching. The route's scope can be effectively ignored as any packet being routed by the device would've been looked-up using the widest scope (UNIVERSE). To achieve that we need to do two changes. Firstly, we need to create another struct (FIB node) that will hold the list of FIB entries sharing the same prefix and length. This struct will be hashed using these two parameters. Secondly, we need to change the route reflection to match the above logic, so that the first FIB entry in the list will be programmed into the device while the rest will remain in the driver's cache in case of subsequent changes.

2017-02-09net/ena: fix potential access to freed memory during device resetNetanel Belgazal
If the ena driver detects that the device is not behave as expected, it tries to reset the device. The reset flow calls ena_down, which will frees all the resources the driver allocates and then it will reset the device. This flow can cause memory corruption if the device is still writes to the driver's memory space. To overcome this potential race, move the reset before the device resources are freed.

ndo_get_stat64() can be called from atomic context, but the current implementation sends an admin command to retrieve the statistics from the device. This admin command can sleep. This patch re-factors the implementation of ena_get_stats64() to use the {rx,tx}bytes/count from the driver's inner counters, and to obtain the rx drop counter from the asynchronous keep alive (heart bit) event.

2017-02-09net/ena: fix NULL dereference when removing the driver after device reset failedNetanel Belgazal
If for some reason the device stops responding, and the device reset failes to recover the device, the mmio register read data structure will not be reinitialized. On driver removal, the driver will also try to reset the device, but this time the mmio data structure will be NULL. To solve this issue, perform the device reset in the remove function only if the device is runnig.

Implement the set_ringparam method, which allows the user to specify the size of the TX and RX descriptor rings. The values are constrained to the limits of the hardware. Since the driver does not use separate queues for mini or jumbo frames, attempts to set those values are rejected.

Add support for RX checksum offload of encapsulated packets. This essentially just means paying attention to the inner checksum flags in the RX event, and if *either* checksum flag indicates a fail then don't tell the kernel that checksum offload was successful. Also, count these checksum errors and export the counts to ethtool -S. Test the most common "good" case of RX events with a single bitmask instead of a series of ifs. Move the more specific error checking in to a separate function for clarity, and don't use unlikely() there since we know at least one of the bits is bad.

This fixes a crash when running out of grant refs when creating many queues across many netdevs. * If creating queues fails (i.e. there are no grant refs available), call xenbus_dev_fatal() to ensure that the xenbus device is set to the closed state. * If no queues are created, don't call xennet_disconnect_backend as netdev->real_num_tx_queues will not have been set correctly. * If setup_netfront() fails, ensure that all the queues created are cleaned up, not just those that have been set up. * If any queues were set up and an error occurs, call xennet_destroy_queues() to clean up the napi context. * If any fatal error occurs, unregister and destroy the netdev to avoid leaving around a half setup network device.

2017-02-09net: phy: Fix PHY module checks and NULL deref in phy_attach_direct()Florian Fainelli
The Generic PHY drivers gets assigned after we checked that the current PHY driver is NULL, so we need to check a few things before we can safely dereference d->driver. This would be causing a NULL deference to occur when a system binds to the Generic PHY driver. Update phy_attach_direct() to do the following: - grab the driver module reference after we have assigned the Generic PHY drivers accordingly, and remember we came from the generic PHY path - update the error path to clean up the module reference in case the Generic PHY probe function fails - split the error path involving phy_detacht() to avoid double free/put since phy_detach() does all the clean up - finally, have phy_detach() drop the module reference count before we call device_release_driver() for the Generic PHY driver case Fixes: cafe8df8b9bc ("net: phy: Fix lack of reference count on PHY driver") Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.
