2016-07-18KEYS: Fix for erroneous trust of incorrectly signed X.509 certsMat Martineau
Arbitrary X.509 certificates without authority key identifiers (AKIs) can be added to "trusted" keyrings, including IMA or EVM certs loaded from the filesystem. Signature verification is currently bypassed for certs without AKIs. Trusted keys were recently refactored, and this bug is not present in 4.6. restrict_link_by_signature should return -ENOKEY (no matching parent certificate found) if the certificate being evaluated has no AKIs, instead of bypassing signature checks and returning 0 (new certificate accepted).

2016-07-16net: cavium: liquidio: Avoid dma_unmap_single on uninitialized ndataFlorian Fainelli
The label lio_xmit_failed is used 3 times through liquidio_xmit() but it always makes a call to dma_unmap_single() using potentially uninitialized variables from "ndata" variable. Out of the 3 gotos, 2 run after ndata has been initialized, and had a prior dma_map_single() call. Fix this by adding a new error label: lio_xmit_dma_failed which does this dma_unmap_single() and then processed with the lio_xmit_failed fallthrough.

2016-07-16vlan: use a valid default mtu value for vlan over macsecPaolo Abeni
macsec can't cope with mtu frames which need vlan tag insertion, and vlan device set the default mtu equal to the underlying dev's one. By default vlan over macsec devices use invalid mtu, dropping all the large packets. This patch adds a netif helper to check if an upper vlan device needs mtu reduction. The helper is used during vlan devices initialization to set a valid default and during mtu updating to forbid invalid, too bit, mtu values. The helper currently only check if the lower dev is a macsec device, if we get more users, we need to update only the helper (possibly reserving an additional IFF bit).

phy-sun4i-usb now has proper dr_mode handling, it always registers an extcon, and sends a notify with the mode (even when in peripheral- / host-only mode) at least once. So we can simply the sunxi musb glue by always registering its extcon notifier and relying on sunxi_musb_work() to enable vbus when in host-only mode. This also enables host- and peripheral-only mode with vbus monitoring.

2016-07-17usb: musb: add tracepoints for register accessBin Liu
This adds tracepoints to musb register read/write wrappers to get trace log for register access. The default tacepoint log prefix here would be musb_readX/writeX(), which is not much helpful. So this patch let the tracepoints use __buildin_return_address(0) to print the caller funciton name to provide more context of the register access.

2016-07-15lkdtm: silence warnings about function declarationsKees Cook
When building under W=1, the lack of lkdtm.h in lkdtm_usercopy.c and lkdtm_rodata.c was discovered. This fixes the issue and consolidates the common header and the pr_fmt macro for simplicity and regularity across each test source file. Signed-off-by: Kees Cook <keescook@chromium.org>

2016-07-15mlxsw: spectrum: Prevent invalid ingress buffer mappingIdo Schimmel
Packets entering the switch are mapped to a Switch Priority (SP) according to their PCP value (untagged frames are mapped to SP 0). The packets are classified to a priority group (PG) buffer in the port's headroom according to their SP. The switch maintains another mapping (SP to IEEE priority), which is used to generate PFC frames for lossless PGs. This mapping is initialized to IEEE = SP % 8. Therefore, when mapping SP 'x' to PG 'y' we create a situation in which an IEEE priority is mapped to two different PGs: IEEE 'x' ---> SP 'x' ---> PG 'y' IEEE 'x' ---> SP 'x + 8' ---> PG '0' (default) Which is invalid, as a flow can use only one PG buffer. Fix this by mapping both SP 'x' and 'x + 8' to the same PG buffer.
