2020-01-16Input: keyspan-remote - fix control-message timeoutsJohan Hovold
The driver was issuing synchronous uninterruptible control requests without using a timeout. This could lead to the driver hanging on probe due to a malfunctioning (or malicious) device until the device is physically disconnected. While sleeping in probe the driver prevents other devices connected to the same hub from being added to (or removed from) the bus. The USB upper limit of five seconds per request should be more than enough.

2020-01-16Input: rmi_f54 - read from FIFO in 32 byte blocksHans Verkuil
The F54 Report Data is apparently read through a fifo and for the smbus protocol that means that between reading a block of 32 bytes the rmiaddr shouldn't be incremented. However, changing that causes other non-fifo reads to fail and so that change was reverted. This patch changes just the F54 function and it now reads 32 bytes at a time from the fifo, using the F54_FIFO_OFFSET to update the start address that is used when reading from the fifo. This has only been tested with smbus, not with i2c or spi. But I suspect that the same is needed there since I think similar problems will occur there when reading more than 256 bytes.

2020-01-16xdp: Use bulking for non-map XDP_REDIRECT and consolidate code pathsToke Høiland-Jørgensen
Since the bulk queue used by XDP_REDIRECT now lives in struct net_device, we can re-use the bulking for the non-map version of the bpf_redirect() helper. This is a simple matter of having xdp_do_redirect_slow() queue the frame on the bulk queue instead of sending it out with __bpf_tx_xdp(). Unfortunately we can't make the bpf_redirect() helper return an error if the ifindex doesn't exit (as bpf_redirect_map() does), because we don't have a reference to the network namespace of the ingress device at the time the helper is called. So we have to leave it as-is and keep the device lookup in xdp_do_redirect_slow(). Since this leaves less reason to have the non-map redirect code in a separate function, so we get rid of the xdp_do_redirect_slow() function entirely. This does lose us the tracepoint disambiguation, but fortunately the xdp_redirect and xdp_redirect_map tracepoints use the same tracepoint entry structures. This means both can contain a map index, so we can just amend the tracepoint definitions so we always emit the xdp_redirect(_err) tracepoints, but with the map ID only populated if a map is present. This means we retire the xdp_redirect_map(_err) tracepoints entirely, but keep the definitions around in case someone is still listening for them. With this change, the performance of the xdp_redirect sample program goes from 5Mpps to 8.4Mpps (a 68% increase). Since the flush functions are no longer map-specific, rename the flush() functions to drop _map from their names. One of the renamed functions is the xdp_do_flush_map() callback used in all the xdp-enabled drivers. To keep from having to update all drivers, use a #define to keep the old name working, and only update the virtual drivers in this patch.

Increase the number of chains and priorities to support the whole range available in tc.

2020-01-16net/mlx5: fs_core: Introduce unmanaged flow tablesPaul Blakey
Currently, Most of the steering tree is statically declared ahead of time, with steering prios instances allocated for each fdb chain to assign max number of levels for each of them. This allows fs_core to manage the connections and levels of the flow tables hierarcy to prevent loops, but restricts us with the number of supported chains and priorities. Introduce unmananged flow tables, allowing the user to manage the flow table connections. A unamanged table is detached from the fs_core flow table hierarcy, and is only connected back to the hierarchy by explicit FTEs forward actions. This will be used together with firmware that supports ignoring the flow table levels to increase the number of supported chains and prios.

2020-01-16IB/mlx4: Fix memory leak in add_gid error flowJack Morgenstein
In procedure mlx4_ib_add_gid(), if the driver is unable to update the FW gid table, there is a memory leak in the driver's copy of the gid table: the gid entry's context buffer is not freed. If such an error occurs, free the entry's context buffer, and mark the entry as available (by setting its context pointer to NULL).

2020-01-16staging: wfx: simplify handling of IEEE80211_TX_CTL_SEND_AFTER_DTIMJérôme Pouiller
When mac80211 ask for a frame to be sent after a DTIM, driver should: 1. Update TIM with multicast bit set (using update_ie). This function can be called whenever. 2. Keep buffered all frames marked "after dtim" 3. When it receive a suspend_resume indication (see wfx_suspend_resume_mc()), send all the buffered frames. This indication is sent by the firmware 4ms before the dtim. 4. If one of the frames returns status "REQUEUE", it means that the DTIM period was ended before to be able to send the frame. 5. When all the buffered frames were sent or if DTIM period was ended, driver should update the TIM with multicast bit reset. All the mess with the asynchronous works can be dropped.

2020-01-16staging: wfx: firmware never return PS status for stationsJérôme Pouiller
At the beginning, firmware could send suspend_resume indication to notify that a station wake up or sleep down. However, mac80211 already handles power save status of stations and this behavior has been removed from the firmware. So now, when suspend_resume indication is received, it is always to notify that a DTIM is about to be sent. So, it is possible to simply wfx_suspend_resume().
