* x86: fix virt_addr_valid() with CONFIG_DEBUG_VIRTUAL=y, v2Vegard Nossum2008-10-131-1/+7
| | | | | | | | | | | | virt_addr_valid() calls __pa(), which calls __phys_addr(). With CONFIG_DEBUG_VIRTUAL=y, __phys_addr() will kill the kernel if the address *isn't* valid. That's clearly wrong for virt_addr_valid(). We also incorporate the debugging checks into virt_addr_valid().

| * | x86: consolidate header guardsVegard Nossum2008-07-221-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is the result of an automatic script that consolidates the format of all the headers in include/asm-x86/. The format: 1. No leading underscore. Names with leading underscores are reserved. 2. Pathname components are separated by two underscores. So we can distinguish between mm_types.h and mm/types.h. 3. Everything except letters and numbers are turned into single underscores. Signed-off-by: Vegard Nossum <vegard.nossum@gmail.com>
* | | x86: track memtype for RAM in page structSuresh Siddha2008-10-101-0/+1
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | Track the memtype for RAM pages in page struct instead of using the memtype list. This avoids the explosion in the number of entries in memtype list (of the order of 20,000 with AGP) and makes the PAT tracking simpler. We are using PG_arch_1 bit in page->flags. We still use the memtype list for non RAM pages.

* | PAGE_ALIGN(): correctly handle 64-bit values on 32-bit architecturesAndrea Righi2008-07-241-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On 32-bit architectures PAGE_ALIGN() truncates 64-bit values to the 32-bit boundary. For example: u64 val = PAGE_ALIGN(size); always returns a value < 4GB even if size is greater than 4GB. The problem resides in PAGE_MASK definition (from include/asm-x86/page.h for example): #define PAGE_SHIFT 12 #define PAGE_SIZE (_AC(1,UL) << PAGE_SHIFT) #define PAGE_MASK (~(PAGE_SIZE-1)) ... #define PAGE_ALIGN(addr) (((addr)+PAGE_SIZE-1)&PAGE_MASK) The "~" is performed on a 32-bit value, so everything in "and" with PAGE_MASK greater than 4GB will be truncated to the 32-bit boundary. Using the ALIGN() macro seems to be the right way, because it uses typeof(addr) for the mask. Also move the PAGE_ALIGN() definitions out of include/asm-*/page.h in include/linux/mm.h.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rusty, in his peevish way, complained that macros defining constants should have a name which somewhat accurately reflects the actual purpose of the constant. Aside from the fact that PTE_MASK gives no clue as to what's actually being masked, and is misleadingly similar to the functionally entirely different PMD_MASK, PUD_MASK and PGD_MASK, I don't really see what the problem is. But if this patch silences the incessent noise, then it will have achieved its goal (TODO: write test-case).

Unfortunately, the generic one doesn't filter out the non-flags bits: this results in lguest creating corrupt shadow page tables and blowing up host memory. Since noone is supposed to use the pfn part of pte_flags(), it seems safest to always do the filtering.

|/ | | | | | | | | | | | | | | | | | | | | | Define PTE_MASK so that it contains a meaningful value for all x86 pagetable configurations. Previously it was defined as a "long" which means that it was too short to cover a 32-bit PAE pte entry. It is now defined as a pteval_t, which is an integer type long enough to contain a full pte (or pmd, pud, pgd). This fixes an Xorg crash on 32-bit x86 with PAE due to corruption of the NX bit in mprotect due to the incorrect type/value of PTE_MASK reported by Hugh Dickins: "Yes, thanks Jeremy: I've checked that each stage builds and runs X on my boxes here, x86_32 and x86_32+PAE and x86_64. (So even 1/8 is enough to fix the PAT pte_modify issue, though 2/8 then fixes compiler warnings.)"

* x86: introduce /dev/mem restrictions with a config optionArjan van de Ven2008-04-241-0/+1
| | | | | | | | | | | | | | | | | | | | | | | This patch introduces a restriction on /dev/mem: Only non-memory can be read or written unless the newly introduced config option is set. The X server needs access to /dev/mem for the PCI space, but it doesn't need access to memory; both the file permissions and SELinux permissions of /dev/mem just make X effectively super-super powerful. With the exception of the BIOS area, there's just no valid app that uses /dev/mem on actual memory. Other popular users of /dev/mem are rootkits and the like. (note: mmap access of memory via /dev/mem was already not allowed since a really long time) People who want to use /dev/mem for kernel debugging can enable the config option. The restrictions of this patch have been in the Fedora and RHEL kernels for at least 4 years without any problems.

Defines arch-specific types for the contents of a pagetable entry. That is, 32-bit entries for 32-bit non-PAE, and 64-bit entries for 32-bit PAE and 64-bit. However, even though the latter two are the same size, they're defined with different types in order to retain compatibility with printk format strings, etc. 2. Defines arch-specific pte_t. This is different because 32-bit PAE defines it in two halves, whereas 32-bit PAE and 64-bit define it as a single entry. All the other pagetable levels can be defined in a common way. This also defines arch-specific pte_val/make_pte functions. 3. Define PAGETABLE_LEVELS for each architecture variation, for later use. 4. Define common pagetable entry accessors in a paravirt-compatible way. (64-bit does not yet use paravirt-ops in any way). 5. Convert a few instances of using a *_val() as an lvalue where it is no longer a macro. There are still places in the 64-bit code which use pte_val() as an lvalue.
