2013-03-19KVM: x86: Convert MSR_KVM_SYSTEM_TIME to use gfn_to_hva_cache functions ↵Andy Honig2-29/+22
(CVE-2013-1797) There is a potential use after free issue with the handling of MSR_KVM_SYSTEM_TIME. If the guest specifies a GPA in a movable or removable memory such as frame buffers then KVM might continue to write to that address even after it's removed via KVM_SET_USER_MEMORY_REGION. KVM pins the page in memory so it's unlikely to cause an issue, but if the user space component re-purposes the memory previously used for the guest, then the guest will be able to corrupt that memory.

2013-03-19KVM: x86: fix for buffer overflow in handling of MSR_KVM_SYSTEM_TIME ↵Andy Honig1-0/+5
(CVE-2013-1796) If the guest sets the GPA of the time_page so that the request to update the time straddles a page then KVM will write onto an incorrect page. The write is done byusing kmap atomic to get a pointer to the page for the time structure and then performing a memcpy to that page starting at an offset that the guest controls. Well behaved guests always provide a 32-byte aligned address, however a malicious guest could use this to corrupt host kernel memory. Tested: Tested against kvmclock unit test.

2013-03-19ARM: video: mxs: Fix mxsfb misconfiguring VDCTRL0Marek Vasut1-12/+12
The issue fixed by this patch manifests only then using X11 with mxsfb driver. The X11 will display either shifted image or otherwise distorted image on the LCD. The problem is that the X11 tries to reconfigure the framebuffer and along the way calls fb_ops.fb_set_par() with X11's desired configuration values. The field of particular interest is fb_info->var.sync which contains non-standard values if configured by kernel. These are either FB_SYNC_DATA_ENABLE_HIGH_ACT, FB_SYNC_DOTCLK_FAILING_ACT or both, depending on the platform configuration. Both of these values are defined in the include/linux/mxsfb.h file. The driver interprets these values and configures the LCD controller accordingly. Yet X11 only has access to the standard values for this field defined in include/uapi/linux/fb.h and thus, unlike kernel, omits these special values. This results in distorted image on the LCD. This patch moves these non-standard values into new field of the mxsfb_platform_data structure so the driver can in turn check this field instead of the video mode field for these specific portions. Moreover, this patch prefixes these values with MXSFB_SYNC_ prefix instead of FB_SYNC_ prefix to prevent confusion of subsequent users.

They fix booting on Cell and G5 among other things (yes, we've been a bit sloppy with older machines this time around)." * 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: powerpc: Rename USER_ESID_BITS* to ESID_BITS* powerpc: Update kernel VSID range powerpc: Make VSID_BITS* dependency explicit powerpc: Make sure that we alays include CONFIG_BINFMT_ELF powerpc/ptrace: Fix brk.len used uninitialised powerpc: Fix -mcmodel=medium breakage in prom_init.c powerpc: Remove last traces of POWER4_ONLY powerpc: Fix cputable entry for 970MP rev 1.0 powerpc: Fix STAB initialization

2013-03-18ARM: fix CONFIG_VIRT_TO_BUS handlingArnd Bergmann2-5/+3
887cbce0 "arch Kconfig: centralise CONFIG_ARCH_NO_VIRT_TO_BUS" and 4febd95a8 "Select VIRT_TO_BUS directly where needed" from Stephen Rothwell changed globally how CONFIG_VIRT_TO_BUS is selected, while my own a5d533ee0 "ARM: disable virt_to_bus/ virt_to_bus almost everywhere" was merged at the same time and changed which platforms select it on ARM. The result of this conflict was that we again see CONFIG_VIRT_TO_BUS on all ARM systems. This patch fixes up the problem and removes CONFIG_ARCH_NO_VIRT_TO_BUS again on ARM.

2013-03-18arm64: fix padding computation in struct ucontextAndreas Schwab1-1/+1
The expression to compute the padding needed to fill the uc_sigmask field to 1024 bits actually computes the padding needed for 1080 bits. Fortunately, due to the 16-byte alignment of the following field (uc_mcontext) the definition in glibc contains enough bytes of padding after uc_sigmask so that the overall offsets and size match in both definitions.

2013-03-18kprobes/x86: Check Interrupt Flag modifier when registering probeMasami Hiramatsu2-1/+5
Currently kprobes check whether the copied instruction modifies IF (interrupt flag) on each probe hit. This results not only in introducing overhead but also involving inat_get_opcode_attribute into the kprobes hot path, and it can cause an infinite recursive call (and kernel panic in the end). Actually, since the copied instruction itself can never be modified on the buffer, it is needless to analyze the instruction on every probe hit. To fix this issue, we check it only once when registering probe and store the result on ainsn->if_modifier.
