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).

[PATCH] mark struct file_operations const 3

2007-02-12T17:48:45+00:00

Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources. Signed-off-by: Arjan van de Ven Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] mspec driver build fix

2006-11-13T15:40:42+00:00

Fix MSPEC driver to build for non SN2 enabled configs as the driver should work in cached and uncached modes (no fetchop) on these systems. In addition make MSPEC select IA64_UNCACHED_ALLOCATOR, which is required for it and move it to arch/ia64/Kconfig to avoid warnings on non ia64 architectures running allmodconfig. Once the Kconfig code is fixed, we can move it back. Signed-off-by: Jes Sorensen Cc: Fernando Luis Vzquez Cao Cc: "Luck, Tony" Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] mspec driver

2006-09-27T15:26:13+00:00

Implement the special memory driver (mspec) based on the do_no_pfn approach. The driver is currently used only on SN2 hardware with special fetchop support but could be beneficial on other architectures using the uncached mode.
