mwifiex records information about various channels as it receives scan information. It does this by appending to a buffer that was sized to the max number of supported channels on any band, but there are numerous problems: (a) scans can return info from more than one band (e.g., both 2.4 and 5 GHz), so the determined "max" is not large enough (b) some firmware appears to return multiple results for a given channel, so the max *really* isn't large enough (c) there is no bounds checking when stashing these stats, so problems (a) and (b) can easily lead to buffer overflows Let's patch this by setting a slightly-more-correct max (that accounts for a combination of both 2.4G and 5G bands) and adding a bounds check when writing to our statistics buffer. Due to problem (b), we still might not properly report all known survey information (e.g., with "iw <dev> survey dump"), since duplicate results (or otherwise "larger than expected" results) will cause some truncation. But that's a problem for a future bugfix. (And because of this known deficiency, only log the excess at the WARN level, since that isn't visible by default in this driver and would otherwise be a bit too noisy.)

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2017-07-25 This series contains updates to i40e and i40evf only. Gustavo Silva fixes a variable assignment, where the incorrect variable was being used to store the error parameter. Carolyn provides a fix for a problem found in systems when entering S4 state, by ensuring that the misc vector's IRQ is disabled as well. Jake removes the single-threaded restriction on the module workqueue, which was causing issues with events such as CORER. Does some future proofing, by changing how the driver displays the UDP tunnel type. Paul adds a retry in releasing resources if the admin queue times out during the first attempt to release the resources. Jesse fixes up references to 32bit timspec, since there are a small set of errors on 32 bit, so we need to be using the right calls for dealing with timespec64 variables. Cleaned up code indentation and corrected an "if" conditional check, as well as making the code flow more clear. Cast or changed the types to remove warnings for comparing signed and unsigned types. Adds missing includes in i40evf, which were being used but were not being directly included. Daniel Borkmann fixes i40e to fill the XDP prog_id with the id just like other XDP enabled drivers, so that on dump we can retrieve the attached program based on the id and dump BPF insns, opcodes, etc back to user space. Tushar Dave adds le32_to_cpu while evaluating the hardware descriptor fields, since they are in little-endian format. Also removed unnecessary "__packed" to a couple of i40evf structures. Stefan Assmann fixes an issue when an administratively set MAC was set and should now be switched back to 00:00:00:00:00:00, the pf_set_mac flag is not being toggled back to false. ==================== Signed-off-by: -

Jeff Kirsher says: ==================== 10GbE Intel Wired LAN Driver Updates 2017-07-25 This series contains updates to ixgbe only. Tony provides all of the changes in the series, starting with adding a check to ensure that adding a MAC filter was successful, before setting the MACVLAN. In order to receive notifications of link configurations of the external PHY and support the configuration of the internal iXFI link on X552 devices, Tony enables LASI interrupts. Update the iXFI driver code flow, since the MAC register NW_MNG_IF_SEL fields have been redefined for X553 devices, so add MAC checks for iXFI flows. Added additional checks for flow control autonegotiation, since it is not support for X553 fiber and XFI devices. v2: removed unnecessary parens noticed by David Miller in patch 6 of the series. v3: dropped patch 6 of the original series, while we work out a more generic solution for malicious driver detection (MDD) support. v4: updated patch 1 of the series with the comments from Joe Perches which were: - switched logic to return on error - return 0 on success - declare retval as an integer ==================== Signed-off-by: -

The i40e driver attempts to display the UDP tunnel name by doing a check against the type, where for non-zero types we use "vxlan" and for zero type we use "geneve". This is not future proof, because if new tunnel types get added, we'll incorrectly label them. It also depends on the value of UDP_TUNNEL_TYPE_GENEVE == 0, which is brittle. Instead, replace this with a function that can return a constant string depending on the type. For now we'll use "unknown" for types we don't know about, and we can expand this in the future if new types get added. Signed-off-by:

The compiler warned on an oddly indented bit of code, and when investigating that, noted that the functions themselves had an odd flow.

During certain events such as a CORER, multiple devices will run a work task to handle some cleanup. This can cause issues due to a single-threaded workqueue which can mean that a device doesn't cleanup in time. Prevent this by removing the single-threaded restriction on the module workqueue. This avoids the need to add more complex yielding logic in our service task routine. This is also similar to what other drivers such as fm10k do. Signed-off-by:
