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.

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.

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 ?

The following set of operations on a NFS client and server will cause server# mkdir a client# cd a server# mv a a.bak client# sleep 30 # (or whatever the dir attrcache timeout is) client# stat . stat: cannot stat `.': Stale NFS file handle Obviously, we should not be getting an ESTALE error back there since the inode still exists on the server. The problem is that the lookup code will call d_revalidate on the dentry that "." refers to, because NFS has FS_REVAL_DOT set. nfs_lookup_revalidate will see that the parent directory has changed and will try to reverify the dentry by redoing a LOOKUP. That of course fails, so the lookup code returns ESTALE. The problem here is that d_revalidate is really a bad fit for this case. What we really want to know at this point is whether the inode is still good or not, but we don't really care what name it goes by or whether the dcache is still valid. Add a new d_op->d_weak_revalidate operation and have complete_walk call that instead of d_revalidate. The intent there is to allow for a "weaker" d_revalidate that just checks to see whether the inode is still good. This is also gives us an opportunity to kill off the FS_REVAL_DOT special casing.

do_mmap_pgoff() rounds up the desired size to the next PAGE_SIZE multiple, however there was no equivalent code in mm_populate(), which caused issues.

When creating new mappings using the MAP_POPULATE / MAP_LOCKED flags (or with MCL_FUTURE in effect), we want to populate the pages within the newly created vmas. This may take a while as we may have to read pages from disk, so ideally we want to do this outside of the write-locked mmap_sem region. This change introduces mm_populate(), which is used to defer populating such mappings until after the mmap_sem write lock has been released. This is implemented as a generalization of the former do_mlock_pages(), which accomplished the same task but was using during mlock() / mlockall().
