2014-04-24rtnetlink: Warn when interface's information won't fit in our packetDavid Gibson1-5/+12
Without IFLA_EXT_MASK specified, the information reported for a single interface in response to RTM_GETLINK is expected to fit within a netlink packet of NLMSG_GOODSIZE. If it doesn't, however, things will go badly wrong, When listing all interfaces, netlink_dump() will incorrectly treat -EMSGSIZE on the first message in a packet as the end of the listing and omit information for that interface and all subsequent ones. This can cause getifaddrs(3) to enter an infinite loop. This patch won't fix the problem, but it will WARN_ON() making it easier to track down what's going wrong.

Eric W. Biederman says: ==================== netlink: Preventing abuse when passing file descriptors. Andy Lutomirski when looking at the networking stack noticed that it is possible to trick privilged processes into calling write on a netlink socket and send netlink messages they did not intend. In particular from time to time there are suid applications that will write to stdout or stderr without checking exactly what kind of file descriptors those are and can be tricked into acting as a limited form of suid cat. In other conversations the magic string CVE-2014-0181 has been used to talk about this issue. This patchset cleans things up a bit, adds some clean abstractions that when used prevent this kind of problem and then finally changes all of the handlers of netlink messages that I could find that call capable to use netlink_ns_capable or an appropriate wrapper. The abstraction netlink_ns_capable verifies that the original creator of the netlink socket a message is sent from had the necessary capabilities as well as verifying that the current sender of a netlink packet has the necessary capabilities. The idea is to prevent file descriptor passing of any form from resulting in a file descriptor that can do more than it can for the creator of the file descriptor. ==================== Signed-off-by: David S.

2014-04-24net: Use netlink_ns_capable to verify the permisions of netlink messagesEric W. Biederman19-36/+38
It is possible by passing a netlink socket to a more privileged executable and then to fool that executable into writing to the socket data that happens to be valid netlink message to do something that privileged executable did not intend to do. To keep this from happening replace bare capable and ns_capable calls with netlink_capable, netlink_net_calls and netlink_ns_capable calls. Which act the same as the previous calls except they verify that the opener of the socket had the desired permissions as well. Reported-by: Andy Lutomirski <[email protected]> Signed-off-by: "Eric W.

The restart/power off implementation in the vexpress driver used to obtain the config function when necessary. This was wrong in two respects: 1. It required memory allocation with disabled interrupts (it worked, but lockdep - when enabled - reported warnings). 2. Used jiffies-based timeout, while jiffies are not running at this stage of system shutdown (therefore a config transaction error - if happened - would have never be reported).

Unfortunately tegra seems to have fallen through the cracks. Fix it. This regression was introduced in commit e13161af80c185ecd8dc4641d0f5df58f9e3e0af Author: Matt Roper <[email protected]> Date: Tue Apr 1 15:22:38 2014 -0700 drm: Add drm_crtc_init_with_planes() (v2) The result was that we've unref'ed the fb for the primary plane twice, leading to a use-after free bug. This is because the drm core will already set crtc->primary->fb to NULL and do the unref for us, and the crtc disable hook is called by the drm crtc helpers for exactly this case. Aside: Now that the fbdev helpers clean up planes there's no longer a need to do this in drivers. So this could probably be nuked entirely in linux-next.

2014-04-24drm/i915: Allow full PPGTT with param overrideBen Widawsky1-1/+1
When PPGTT was disabled by default, the patch also prevented the user from overriding this behavior via module parameter. Being able to test this on arbitrary kernels is extremely beneficial to track down the remaining bugs. The patch that prevented this was: commit 93a25a9e2d67765c3092bfaac9b855d95e39df97 Author: Daniel Vetter <[email protected]> Date: Thu Mar 6 09:40:43 2014 +0100 drm/i915: Disable full ppgtt by default By default PPGTT is set to -1. 0 means off, 1 means aliasing only, 2 means full, all other values are reserved.

2014-04-24drm/i915: Discard BIOS framebuffers too small to accommodate chosen modeChris Wilson1-0/+10
If the inherited BIOS framebuffer is smaller than the mode selected for fbdev, then if we continue to use it then we cause display corruption as we do not setup the panel fitter to upscale.

2014-04-24perf/x86: Fix RAPL rdmsrl_safe() usageStephane Eranian1-1/+2
This patch fixes a bug introduced by: 24223657806a ("perf/x86/intel: Use rdmsrl_safe() when initializing RAPL PMU") The rdmsrl_safe() function returns 0 on success. The current code was failing to detect the RAPL PMU on real hardware (missing /sys/devices/power) because the return value of rdmsrl_safe() was misinterpreted.

2014-04-24PNP: Work around BIOS defects in Intel MCH area reportingBjorn Helgaas1-0/+79
Work around BIOSes that don't report the entire Intel MCH area. MCHBAR is not an architected PCI BAR, so MCH space is usually reported as a PNP0C02 resource. The MCH space was once 16KB, but is 32KB in newer parts. Some BIOSes still report a PNP0C02 resource that is only 16KB, which means the rest of the MCH space is consumed but unreported. This can cause resource map sanity check warnings or (theoretically) a device conflict if we assigned the unreported space to another device. The Intel perf event uncore driver tripped over this when it claimed the MCH region: resource map sanity check conflict: 0xfed10000 0xfed15fff 0xfed10000 0xfed13fff pnp 00:01 Info: mapping multiple BARs. Your kernel is fine. To prevent this, if we find a PNP0C02 resource that covers part of the MCH space, extend it to cover the entire space.
