2016-05-02cxgb3: fix out of bounds readMichal Schmidt1-1/+2
An out of bounds read of 2 bytes was discovered in cxgb3 with KASAN. t3_config_rss() expects both arrays it gets as parameters to have terminators. setup_rss(), the caller, forgets to add a terminator to one of the arrays. Thankfully the iteration in t3_config_rss() stops anyway, but in the last iteration the check for the terminator is an out of bounds read. Add the missing terminator to rspq_map[].

2016-05-02net/smscx5xx: use the device tree for mac addressArnd Bergmann2-2/+22
This takes the MAC address for smsc75xx/smsc95xx USB network devices from a the device tree. This is required to get a usable persistent address on the popular beagleboard, whose hardware designers accidentally forgot that an ethernet device really requires an a MAC address to be functional. The Raspberry Pi also ships smsc9514 without a serial EEPROM, stores the MAC address in ROM accessible via VC4 firmware. The smsc75xx and smsc95xx drivers are just two copies of the same code, so better fix both.

2016-04-30gpiolib-acpi: Duplicate con_id string when adding it to the crs lookup listVille Syrjälä1-1/+1
Calling gpiod_get() from a module and then unloading the module leads to an oops due to acpi_can_fallback_to_crs() storing the pointer to the passed 'con_id' string onto acpi_crs_lookup_list. The next guy to come along will then try to access the string but the memory may now be gone with the module. Make a copy of the passed string instead, and store the copy on the list.

Both of these drivers can return NOTIFY_BAD, but this terminates processing other callbacks that were registered later on the chain. Since the driver did nothing to log the error it seems wrong to prevent other interested parties from seeing it. E.g. neither of them had even bothered to check the type of the error to see if it was a memory error before the return NOTIFY_BAD.

2016-04-29drivers: net: cpsw: use of_phy_connect() in fixed-link caseDavid Rivshin1-10/+1
If a fixed-link DT subnode is used, the phy_device was looked up so that a PHY ID string could be constructed and passed to phy_connect(). This is not necessary, as the device_node can be passed directly to of_phy_connect() instead. This reuses the same codepath as if the phy-handle DT property was used.

The phy-mode emac property was only being processed in the phy_id or fixed-link cases. However if phy-handle was specified instead, an error message would complain about the lack of phy_id or fixed-link, and then jump past the of_get_phy_mode(). This would result in the PHY mode defaulting to MII, regardless of what the devicetree specified.

2016-04-29drivers: net: cpsw: fix segfault in case of bad phy-handleDavid Rivshin1-13/+22
If an emac node has a phy-handle property that points to something which is not a phy, then a segmentation fault will occur when the interface is brought up. This is because while phy_connect() will return ERR_PTR() on failure, of_phy_connect() will return NULL. The common error check uses IS_ERR(), and so missed when of_phy_connect() fails. The NULL pointer is then dereferenced. Also, the common error message referenced slave->data->phy_id, which would be empty in the case of phy-handle. Instead, use the name of the device_node as a useful identifier. And in the phy_id case add the error code for completeness.

2016-04-29drivers: net: cpsw: fix parsing of phy-handle DT property in dual_emac configDavid Rivshin2-7/+7
Commit 9e42f715264ff158478fa30eaed847f6e131366b ("drivers: net: cpsw: add phy-handle parsing") saved the "phy-handle" phandle into a new cpsw_priv field. However, phy connections are per-slave, so the phy_node field should be in cpsw_slave_data rather than cpsw_priv. This would go unnoticed in a single emac configuration. But in dual_emac mode, the last "phy-handle" property parsed for either slave would be used by both of them, causing them both to refer to the same phy_device.

2016-04-28IB/security: Restrict use of the write() interfaceJason Gunthorpe6-1/+24
The drivers/infiniband stack uses write() as a replacement for bi-directional ioctl(). This is not safe. There are ways to trigger write calls that result in the return structure that is normally written to user space being shunted off to user specified kernel memory instead. For the immediate repair, detect and deny suspicious accesses to the write API. For long term, update the user space libraries and the kernel API to something that doesn't present the same security vulnerabilities (likely a structured ioctl() interface). The impacted uAPI interfaces are generally only available if hardware from drivers/infiniband is installed in the system.
