linux-stable.git/drivers, branch v3.14.70 Linux kernel stable tree atl2: Disable unimplemented scatter/gather feature 2016-05-19T00:04:01+00:00 Ben Hutchings ben@decadent.org.uk 2016-04-20T22:23:08+00:00 d6b8a68ac7b6d2e241f8d34b769c98a1793d9124 [ Upstream commit f43bfaeddc79effbf3d0fcb53ca477cca66f3db8 ] atl2 includes NETIF_F_SG in hw_features even though it has no support for non-linear skbs. This bug was originally harmless since the driver does not claim to implement checksum offload and that used to be a requirement for SG.

[ Upstream commit f43bfaeddc79effbf3d0fcb53ca477cca66f3db8 ]

atl2 includes NETIF_F_SG in hw_features even though it has no support
for non-linear skbs.  This bug was originally harmless since the
driver does not claim to implement checksum offload and that used to
be a requirement for SG.

Now that SG and checksum offload are independent features, if you
explicitly enable SG *and* use one of the rare protocols that can use
SG without checkusm offload, this potentially leaks sensitive
information (before you notice that it just isn't working).  Therefore
this obscure bug has been designated CVE-2016-2117.

drm/i915: Bail out of pipe config compute loop on LPT 2016-05-19T00:03:59+00:00 Daniel Vetter daniel.vetter@ffwll.ch 2016-05-03T08:33:01+00:00 dfc2079ba67e4bd5b3ee88d59952a174a7f1272f commit 2700818ac9f935d8590715eecd7e8cadbca552b6 upstream. LPT is pch, so might run into the fdi bandwidth constraint (especially since it has only 2 lanes). But right now we just force pipe_bpp back to 24, resulting in a nice loop (which we bail out with a loud WARN_ON). Fix this.
