vm audit: add VM_DONTEXPAND to mmap for drivers that need it (CVE-2008-0007)

2008-02-06T19:43:46+00:00

Drivers that register a ->fault handler, but do not range-check the offset argument, must set VM_DONTEXPAND in the vm_flags in order to prevent an expanding mremap from overflowing the resource. I've audited the tree and attempted to fix these problems (usually by adding VM_DONTEXPAND where it is not obvious).

drm/i915: Fix i965 secured batchbuffer usage (CVE-2007-3851)

2007-08-09T21:27:32+00:00

This 965G and above chipsets moved the batch buffer non-secure bits to another place. This means that previous drm's allowed in-secure batchbuffers to be submitted to the hardware from non-privileged users who are logged into X and and have access to direct rendering.

fix radeon setparam on 32/64 systems, harder.

2007-06-16T16:39:05+00:00

Commit 9b01bd5b284bbf519b726b39f1352023cb5e9e69 introduced a compat_ioctl handler for RADEON_SETPARAM, the sole purpose of which was to handle the fact that on i386, alignof(uint64_t)==4. Unfortunately, this handler was installed for _all_ 64-bit architectures, instead of only x86_64 and ia64. And thus it breaks 32-bit compatibility on every other arch, where 64-bit integers are aligned to 8 bytes in 32-bit mode just the same as in 64-bit mode. Arnd has a cunning plan to use 'compat_u64' with appropriate alignment attributes according to the 32-bit ABI, but for now let's just make the compat_radeon_cp_setparam routine entirely disappear on 64-bit machines whose 32-bit compat support isn't for i386. It would be a no-op with compat_u64 anyway. Signed-off-by: David Woodhouse Acked-by: Arnd Bergmann Cc: Benjamin Herrenschmidt Cc: Dave Airlie Signed-off-by: Linus Torvalds

drm: fix radeon setparam on 32/64 bit systems.

The alignment on 64-bit is different for 64-bit values. Signed-off-by: Dave Airlie

drm/i915: Add support for the G33, Q33, and Q35 chipsets.

2007-06-10T05:58:19+00:00

These require that the status page be referenced by a pointer in GTT, rather than phsyical memory. So, we have the X Server allocate that memory and tell us the address, instead. Signed-off-by: Dave Airlie

[SPARC]: Mark as emulating cmpxchg, add appropriate depends for DRM.

2007-05-29T09:51:24+00:00

The DRM code depends on an atomic version of cmpxchg(), which is not available on sparc32. Since other platforms besides sparc32 have this issue a KCONFIG option is added for it. Signed-off-by: Martin Habets Signed-off-by: David S. Miller
