* [PATCH] Hugetlb: Copy on Write supportDavid Gibson2006-01-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement copy-on-write support for hugetlb mappings so MAP_PRIVATE can be supported. This helps us to safely use hugetlb pages in many more applications. The patch makes the following changes. If needed, I also have it broken out according to the following paragraphs. 1. Add a pair of functions to set/clear write access on huge ptes. The writable check in make_huge_pte is moved out to the caller for use by COW later. 2. Hugetlb copy-on-write requires special case handling in the following situations: - copy_hugetlb_page_range() - Copied pages must be write protected so a COW fault will be triggered (if necessary) if those pages are written to. - find_or_alloc_huge_page() - Only MAP_SHARED pages are added to the page cache. MAP_PRIVATE pages still need to be locked however. 3. Provide hugetlb_cow() and calls from hugetlb_fault() and hugetlb_no_page() which handles the COW fault by making the actual copy. 4. Remove the check in hugetlbfs_file_map() so that MAP_PRIVATE mmaps will be allowed. Make MAP_HUGETLB exempt from the depricated VM_RESERVED mapping check.

| * [PATCH] add AOP_TRUNCATED_PAGE, prepend AOP_ to WRITEPAGE_ACTIVATEZach Brown2006-01-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | readpage(), prepare_write(), and commit_write() callers are updated to understand the special return code AOP_TRUNCATED_PAGE in the style of writepage() and WRITEPAGE_ACTIVATE. AOP_TRUNCATED_PAGE tells the caller that the callee has unlocked the page and that the operation should be tried again with a new page. OCFS2 uses this to detect and work around a lock inversion in its aop methods. There should be no change in behaviour for methods that don't return AOP_TRUNCATED_PAGE. WRITEPAGE_ACTIVATE is also prepended with AOP_ for consistency and they are made enums so that kerneldoc can be used to document their semantics. Signed-off-by: Zach Brown <zach.brown@oracle.com>

Since block/scsi_ioctl.c SG_IO was already testing against max_sectors and SCSI-ml was setting max_sectors and max_hw_sectors to the same value this does not change any scsi SG_IO behavior. It only prepares ll_rw_blk.c, scsi_ioctl.c and bio.c for when SCSI-ml begins to set a valid max_hw_sectors for all LLDs. Today if a LLD does not set it SCSI-ml sets it to a safe default and some LLDs set it to a artificial low value to overcome memory and feedback issues. Note: Since we now cap max_sectors to BLK_DEF_MAX_SECTORS, which is 1024, drivers that used to call blk_queue_max_sectors with a large value of max_sectors will now see the fs requests capped to BLK_DEF_MAX_SECTORS.

Per Jens's previous comments, I placed this function in scsi_lib.c. I made it follow all the queue's limits - I think I did at least :), so I removed the warning on the function header. I think the scsi_execute_* functions should eventually take a request_queue and be placed some place where the dm-multipath hw_handler can use them if that failover code is going to stay in the kernel.

* [PATCH] Fix listxattr() for generic security attributesDaniel Drake2005-12-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit f549d6c18c0e8e6cf1bf0e7a47acc1daf7e2cec1 introduced a generic fallback for security xattrs, but appears to include a subtle bug. Gentoo users with kernels with selinux compiled in, and coreutils compiled with acl support, noticed that they could not copy files on tmpfs using 'cp'. cp (compiled with acl support) copies the file, lists the extended attributes on the old file, copies them all to the new file, and then exits. However the listxattr() calls were failing with this odd behaviour: llistxattr("a.out", (nil), 0) = 17 llistxattr("a.out", 0x7fffff8c6cb0, 17) = -1 ERANGE (Numerical result out of range) I believe this is a simple problem in the logic used to check the buffer sizes; if the user sends a buffer the exact size of the data, then its ok :) This change solves the problem.
