There is no documented methods to mark FAT as dirty. Unofficially MS started to use reserved Byte in boot sector for this purpose, at least since Win 2000. With Win 7 user is warned if fs is dirty and asked to clean it. Different versions of Win, handle it in different ways, but always have same meaning: - Win 2000 and XP, set it on write operations and remove it after operation was finnished - Win 7, set dirty flag on first write and remove it on umount. We will do it as follows: - set dirty flag on mount. If fs was initially dirty, warn user, remember it and do not do any changes to boot sector. - clean it on umount. If fs was initially dirty, leave it dirty. - do not do any thing if fs mounted read-only. - TODO: leave fs dirty if we found some error after mount. Signed-off-by:

The fsck_hfs (under MacOS X) complains about unzeroed unused b-tree nodes after deletion of folders' tree under Linux. SYMPTOMS: Running Disk Utiltiy's "Verify Disk" on "test" gives the following: Verifying volume “Test” Checking file systemChecking Journaled HFS Plus volume. Checking extents overflow file. Checking catalog file. Unused node is not erased (node = 3111) Checking multi-linked files. Checking catalog hierarchy. Checking extended attributes file. Checking volume bitmap. Checking volume information. The volume Test was found corrupt and needs to be repaired. Error: This disk needs to be repaired. Click Repair Disk. REPRODUCING PATH: 1. Prepare HFS+ (non-case sensitive) partition (for example, 5GB) under MacOS X. 2. Copy linux kernel source tree (for example, 3.7-rc6 version) on this partition under MacOS X. 3. Then switch to Linux and mount this prepared partition. 4. Execute `sudo rm -r` under prepared directory with linux kernel source tree. 5. Unmount and boot back into OS X. 6. Open up Disk Utility and verify partition. REPRODUCIBILITY: 100% FIX: It is added code of node clearing in hfs_bnode_put() method for the case when node has flag HFS_BNODE_DELETED. Signed-off-by:

hfsplus: reworked support of extended attributes. Current mainline implementation of hfsplus file system driver treats as extended attributes only two fields (fdType and fdCreator) of user_info field in file description record (struct hfsplus_cat_file). It is possible to get or set only these two fields as extended attributes. But HFS+ treats as com.apple.FinderInfo extended attribute an union of user_info and finder_info fields as for file (struct hfsplus_cat_file) as for folder (struct hfsplus_cat_folder). Moreover, current mainline implementation of hfsplus file system driver doesn't support special metadata file - attributes tree. Mac OS X 10.4 and later support extended attributes by making use of the HFS+ filesystem Attributes file B*-tree feature which allows for named forks. Mac OS X supports only inline extended attributes, limiting their size to 3802 bytes. Any regular file may have a list of extended attributes. HFS+ supports an arbitrary number of named forks. Each attribute is denoted by a name and the associated data. The name is a null-terminated Unicode string. It is possible to list, to get, to set, and to remove extended attributes from files or directories. It exists some peculiarity during getting of extended attributes list by means of getfattr utility. The getfattr utility expects prefix "user." before any extended attribute's name. So, it ignores any names that don't contained such prefix. Such behavior of getfattr utility results in unexpected empty output of extended attributes list even in the case when file (or folder) contains extended attributes. It needs to use empty string as regular expression pattern for names matching (getfattr --match=""). For support of extended attributes in HFS+: 1. It was added necessary on-disk layout declarations related to Attributes tree into hfsplus_raw.h file. 2. It was added attributes.c file with implementation of functionality of manipulation by records in Attributes tree. 3. It was reworked hfsplus_listxattr, hfsplus_getxattr, hfsplus_setxattr functions in ioctl.c. Moreover, it was added hfsplus_removexattr method. This patch: Add osx.* prefix for handling namespace of Mac OS X extended attributes. [akpm@linux-foundation.org: checkpatch fixes] Signed-off-by:

For better code reuse use the newly added page iterator to iterate through the pages. The offset, length within the page is still calculated by the mapping iterator as well as the actual mapping. Idea from Tejun Heo. Signed-off-by:

Add an iterator to walk through a scatter list a page at a time starting at a specific page offset. As opposed to the mapping iterator this is meant to be small, performing well even in simple loops like collecting all pages on the scatterlist into an array or setting up an iommu table based on the pages' DMA address.

The intent is to ensure that all Tegra-related patches are sent to the linux-tegra@ mailing list, so people can keep up-to-date on all misc driver changes. Doing this with a keyword is far simpler and more compact than listing all Tegra-related drivers, even if wildcards were used. Words such as integrate or integrator are common. Ensure the character right before "tegra" isn't a-z (case-insensitive), to make sure the keyword doesn't match those. The only files that the keyword doesn't match are the NVEC driver. Add the linux-tegra mailing list to the NVEC entry to solve this. Signed-off-by:

Allow K: entries in MAINTAINERS to match directly against filenames; either those extracted from patch +++ or --- lines, or those specified on the command-line using the -f option. This potentially allows fewer lines in a MAINTAINERS entry, if all the relevant files are scattered throughout the whole kernel tree, yet contain some common keyword. An example would be using an ARM SoC name as the keyword to catch all related drivers. I don't think setting exact_pattern_match_hash would be appropriate here; at least for intended Tegra use case, this feature is to ensure that all Tegra-related driver changes get Cc'd to the Tegra mailing list. Setting exact_pattern_match_hash would prevent git history parsing for e.g. S-o-b tags, which still seems like it would be useful. Hence, this flag isn't set. Signed-off-by:

__orderly_poweroff() does argv_free() if call_usermodehelper_fns() returns -ENOMEM. As Lucas pointed out, this can be wrong if -ENOMEM was not triggered by the failing call_usermodehelper_setup(), in this case both __orderly_poweroff() and argv_cleanup() can do kfree(). Kill argv_cleanup() and change __orderly_poweroff() to call argv_free() unconditionally like do_coredump() does. This info->cleanup() is not needed (and wrong) since 6c0c0d4d "fix bug in orderly_poweroff() which did the UMH_NO_WAIT => UMH_WAIT_EXEC change, we can rely on the fact that CLONE_VFORK can't return until do_execve() succeeds/fails.

ocfs2_block_group_alloc_discontig() disables chain relink by setting ac->ac_allow_chain_relink = 0 because it grabs clusters from multiple cluster groups. It doesn't keep the credits for all chain relink,but ocfs2_claim_suballoc_bits overrides this in this call trace: ocfs2_block_group_claim_bits()->ocfs2_claim_clusters()-> __ocfs2_claim_clusters()->ocfs2_claim_suballoc_bits() ocfs2_claim_suballoc_bits set ac->ac_allow_chain_relink = 1; then call ocfs2_search_chain() one time and disable it again, and then we run out of credits. Fix is to allow relink by default and disable it in ocfs2_block_group_alloc_discontig. Without this patch, End-users will run into a crash due to run out of credits, backtrace like this: RIP: 0010:[<ffffffffa0808b14>] [<ffffffffa0808b14>] jbd2_journal_dirty_metadata+0x164/0x170 [jbd2] RSP: 0018:ffff8801b919b5b8 EFLAGS: 00010246 RAX: 0000000000000000 RBX: ffff88022139ddc0 RCX: ffff880159f652d0 RDX: ffff880178aa3000 RSI: ffff880159f652d0 RDI: ffff880087f09bf8 RBP: ffff8801b919b5e8 R08: 0000000000000000 R09: 0000000000000000 R10: 0000000000001e00 R11: 00000000000150b0 R12: ffff880159f652d0 R13: ffff8801a0cae908 R14: ffff880087f09bf8 R15: ffff88018d177800 FS: 00007fc9b0b6b6e0(0000) GS:ffff88022fd40000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b CR2: 000000000040819c CR3: 0000000184017000 CR4: 00000000000006e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process dd (pid: 9945, threadinfo ffff8801b919a000, task ffff880149a264c0) Call Trace: ocfs2_journal_dirty+0x2f/0x70 [ocfs2] ocfs2_relink_block_group+0x111/0x480 [ocfs2] ocfs2_search_chain+0x455/0x9a0 [ocfs2] ...

We need to re-initialize the security for a new reflinked inode with its parent dirs if it isn't specified to be preserved for ocfs2_reflink(). However, the code logic is broken at ocfs2_init_security_and_acl() although ocfs2_init_security_get() succeed. As a result, ocfs2_acl_init() does not involked and therefore the default ACL of parent dir was missing on the new inode. Note this was introduced by 9d8f13ba ("security: new security_inode_init_security API adds function callback") To reproduce: set default ACL for the parent dir(ocfs2 in this case): $ setfacl -m default:user:jeff:rwx ../ocfs2/ $ getfacl ../ocfs2/ # file: ../ocfs2/ # owner: jeff # group: jeff user::rwx group::r-x other::r-x default:user::rwx default:user:jeff:rwx default:group::r-x default:mask::rwx default:other::r-x $ touch a $ getfacl a # file: a # owner: jeff # group: jeff user::rw- group::rw- other::r-- Before patching, create reflink file b from a, the user default ACL entry(user:jeff:rwx)was missing: $ ./ocfs2_reflink a b $ getfacl b # file: b # owner: jeff # group: jeff user::rw- group::rw- other::r-- In this case, the end user can also observed an error message at syslog: (ocfs2_reflink,3229,2):ocfs2_init_security_and_acl:7193 ERROR: status = 0 After applying this patch, create reflink file c from a: $ ./ocfs2_reflink a c $ getfacl c # file: c # owner: jeff # group: jeff user::rw- user:jeff:rwx #effective:rw- group::r-x #effective:r-- mask::rw- other::r-- Test program: /* Usage: reflink <source> <dest> */ #include <stdio.h> #include <stdint.h> #include <stdbool.h> #include <string.h> #include <errno.h> #include <sys/types.h> #include <sys/stat.h> #include <fcntl.h> #include <sys/ioctl.h> static int reflink_file(char const *src_name, char const *dst_name, bool preserve_attrs) { int fd; #ifndef REFLINK_ATTR_NONE # define REFLINK_ATTR_NONE 0 #endif #ifndef REFLINK_ATTR_PRESERVE # define REFLINK_ATTR_PRESERVE 1 #endif #ifndef OCFS2_IOC_REFLINK struct reflink_arguments { uint64_t old_path; uint64_t new_path; uint64_t preserve; }; # define OCFS2_IOC_REFLINK _IOW ('o', 4, struct reflink_arguments) #endif struct reflink_arguments args = { .old_path = (unsigned long) src_name, .new_path = (unsigned long) dst_name, .preserve = preserve_attrs ?

Commit ef5da59f ("scripts/kernel-doc: handle struct member __aligned") permits "char something [123] __aligned(8);". However, by using \d we constraint ourselves with integers. This is not always the case. In fact, it might be better to do char something[123] __aligned(sizeof(u16)); For example, With wireless_dev defining: u8 address[ETH_ALEN] __aligned(sizeof(u16)); With \d, scripts/kernel-doc erroneously says: Warning(include/net/cfg80211.h:2618): Excess struct/union/enum/typedef member 'address' description in 'wireless_dev' This is because the regex __aligned\s*\(\d+\) fails match at \d as sizeof is used. So replace \d with . to indicate "something" in kernel-doc to ignore __aligned(SOMETHING) in structs. With this change, we can use integers OR sizeof() or macros as we please. Signed-off-by:

munlock_vma_pages_range() was always incrementing addresses by PAGE_SIZE at a time. When munlocking THP pages (or the huge zero page), this resulted in taking the mm->page_table_lock 512 times in a row. We can do better by making use of the page_mask returned by follow_page_mask (for the huge zero page case), or the size of the page munlock_vma_page() operated on (for the true THP page case).

When taking an address of an extern array, gcc quite naturally should be able to say "an address of an object can never be NULL" and just optimize away the test entirely. However, the new alternate sysrq reset code (commit 154b7a48: "Input: sysrq - allow specifying alternate reset sequence") did exactly that, and declared platform_sysrq_reset_seq[] as a weak array, and expecting that testing the address of the array would show whether it actually got linked against something or not. And that doesn't work with all gcc versions. Clearly it works with *some* versions of gcc, and maybe it's even supposed to work, but it really is a very fragile concept. So instead of testing the address of the weak variable, just create a weak instance of that array that is empty. If some platform then has a real platform_sysrq_reset_seq[] that overrides our weak one, the linker will switch to that one, and it all works without any run-time conditionals at all. Reported-by:

The stack vma is designed to grow automatically (marked with VM_GROWSUP or VM_GROWSDOWN depending on architecture) when an access is made beyond the existing boundary. However, particularly if you have not limited your stack at all ("ulimit -s unlimited"), this can cause the stack to grow even if the access was really just one past *another* segment. And that's wrong, especially since we first grow the segment, but then immediately later enforce the stack guard page on the last page of the segment. So _despite_ first growing the stack segment as a result of the access, the kernel will then make the access cause a SIGSEGV anyway! So do the same logic as the guard page check does, and consider an access to within one page of the next segment to be a bad access, rather than growing the stack to abut the next segment.

Pull ext4 updates from Theodore Ts'o: "The one new feature added in this patch series is the ability to use the "punch hole" functionality for inodes that are not using extent maps. In the bug fix category, we fixed some races in the AIO and fstrim code, and some potential NULL pointer dereferences and memory leaks in error handling code paths. In the optimization category, we fixed a performance regression in the jbd2 layer introduced by commit d9b01934 ("jbd: fix fsync() tid wraparound bug", introduced in v3.0) which shows up in the AIM7 benchmark. We also further optimized jbd2 by minimize the amount of time that transaction handles are held active. This patch series also features some additional enhancement of the extent status tree, which is now used to cache extent information in a more efficient/compact form than what we use on-disk." * tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4: (65 commits) ext4: fix free clusters calculation in bigalloc filesystem ext4: no need to remove extent if len is 0 in ext4_es_remove_extent() ext4: fix xattr block allocation/release with bigalloc ext4: reclaim extents from extent status tree ext4: adjust some functions for reclaiming extents from extent status tree ext4: remove single extent cache ext4: lookup block mapping in extent status tree ext4: track all extent status in extent status tree ext4: let ext4_ext_map_blocks return EXT4_MAP_UNWRITTEN flag ext4: rename and improbe ext4_es_find_extent() ext4: add physical block and status member into extent status tree ext4: refine extent status tree ext4: use ERR_PTR() abstraction for ext4_append() ext4: refactor code to read directory blocks into ext4_read_dirblock() ext4: add debugging context for warning in ext4_da_update_reserve_space() ext4: use KERN_WARNING for warning messages jbd2: use module parameters instead of debugfs for jbd_debug ext4: use module parameters instead of debugfs for mballoc_debug ext4: start handle at the last possible moment when creating inodes ext4: fix the number of credits needed for acl ops with inline data ...
