What sounds\nlike a clever micro-optimization actually is nast trap for many filesystems.\n\nFor many modern filesystems i_size or other inode information is only\nupdated on I/O completion and we need to wait for I/O to finish before\nwe can write out the metadata. For old fashionen filesystems that\ninstanciate blocks during the actual write and also update the metadata\nat that point it opens up a large window were we could expose uninitialized\nblocks after a crash. While a few filesystems that need it already wait\nfor the I/O to finish inside their -\u003efsync methods it is rather suboptimal\nas it is done under the i_mutex and also always for the whole file instead\nof just a part as we could do for O_SYNC handling.\n\nHere is a small audit of all fsync instances in the tree:\n\n - spufs_mfc_fsync:\n - ps3flash_fsync:\n - vol_cdev_fsync:\n - printer_fsync:\n - fb_deferred_io_fsync:\n - bad_file_fsync:\n - simple_sync_file:\n\n\tdon\u0027t care - filesystems/drivers do\u0027t use the page cache or are\n\tpurely in-memory.\n\n - simple_fsync:\n - file_fsync:\n - affs_file_fsync:\n - fat_file_fsync:\n - jfs_fsync:\n - ubifs_fsync:\n - reiserfs_dir_fsync:\n - reiserfs_sync_file:\n\n\tnever touch pagecache themselves. We need to wait before if we do\n\tnot want to expose stale data after an allocation.\n\n - afs_fsync:\n - fuse_fsync_common:\n\n\tdo the waiting writeback itself in awkward ways, would benefit from\n\tproper semantics\n\n - block_fsync:\n\n\tDoes a filemap_write_and_wait on the block device inode. Because we\n\tnow have f_mapping that is the same inode we call it on in vfs_fsync.\n\tSo just removing it and letting the VFS do the work in one go would\n\tbe an improvement.\n\n - btrfs_sync_file:\n - cifs_fsync:\n - xfs_file_fsync:\n\n\tneed the wait first and currently do it themselves. would benefit from\n\tdoing it outside i_mutex.\n\n - coda_fsync:\n - ecryptfs_fsync:\n - exofs_file_fsync:\n - shm_fsync:\n\n\tonly passes the fsync through to the lower layer\n\n - ext3_sync_file:\n\n\tdoesn\u0027t seem to care, comments are confusing.\n\n - ext4_sync_file:\n\n\twould need the wait to work correctly for delalloc mode with late\n\ti_size updates. Otherwise the ext3 comment applies.\n\n\tcurrently implemens it\u0027s own writeback and wait in an odd way,\n\tcould benefit from doing it properly.\n\n - gfs2_fsync:\n\n\tnot needed for journaled data mode, but probably harmless there.\n\tCurrently writes back data asynchronously itself. Needs some\n\tmajor audit.\n\n - hostfs_fsync:\n\n\tjust calls fsync/datasync on the host FD. Without the wait before\n\tdata might not even be inflight yet if we\u0027re unlucky.\n\n - hpfs_file_fsync:\n - ncp_fsync:\n\n\tno-ops. Dangerous before and after.\n\n - jffs2_fsync:\n\n\tjust calls jffs2_flush_wbuf_gc, not sure how this relates to data.\n\n - nfs_fsync_dir:\n\n\tjust increments stats, claims all directory operations are synchronous\n\n - nfs_file_fsync:\n\n\tonly writes out data??? Looks very odd.\n\n - nilfs_sync_file:\n\n\tlooks like it expects all data done, but not sure from the code\n\n - ntfs_dir_fsync:\n - ntfs_file_fsync:\n\n\tappear to do their own data writeback. Very convoluted code.\n\n - ocfs2_sync_file:\n\n\tdoes it\u0027s own data writeback, but no wait. probably needs the wait.\n\n - smb_fsync:\n\n\taccording to a comment expects all pages written already, probably needs\n\tthe wait before.\n\nThis patch only changes vfs_fsync_range, removal of the wait in the methods\nthat have it is left to the filesystem maintainers. Note that most\nfilesystems really do need an audit for their fsync methods given the\ngems found in this very brief audit.\n\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: Jan Kara \u003cjack@suse.cz\u003e\n" }, { "commit": "18f2ee705d98034b0f229a3202d827468d4bffd9", "tree": "1da282e5eb90dc8e8a1e46214e0e7639138d3568", "parents": [ "2f3d675bcd4a84251d6e8eea8096ec8fc795e5d6" ], "author": { "name": "Jan Kara", "email": "jack@suse.cz", "time": "Tue Aug 18 18:43:15 2009 +0200" }, "committer": { "name": "Jan Kara", "email": "jack@suse.cz", "time": "Mon Sep 14 17:08:17 2009 +0200" }, "message": "vfs: Remove generic_osync_inode() and sync_page_range{_nolock}()\n\nRemove these three functions since nobody uses them anymore.\n\nSigned-off-by: Jan Kara \u003cjack@suse.cz\u003e\n" }, { "commit": "2f3d675bcd4a84251d6e8eea8096ec8fc795e5d6", "tree": "3b186e4960d4553fac577be5f1def6d17196beca", "parents": [ "aa3caafe53cab7ef60605e481cd5d7943e1c3022" ], "author": { "name": "Jan Kara", "email": "jack@suse.cz", "time": "Mon Aug 17 17:00:02 2009 +0200" }, "committer": { "name": "Jan Kara", "email": "jack@suse.cz", "time": "Mon Sep 14 17:08:17 2009 +0200" }, "message": "fat: Opencode sync_page_range_nolock()\n\nfat_cont_expand() is the only user of sync_page_range_nolock().

The patch uses hooks introduced in the\nprevious patch to handle the getting and setting of security information for\nthe sysfs inodes. As was suggested by Eric Biederman the struct iattr in the\nsysfs_dirent structure has been replaced by a structure which contains the\niattr, secdata and secdata length to allow the changes to persist in the event\nthat the inode representing the sysfs_dirent is evicted. Because sysfs only\nstores this information when a change is made all the optional data is moved\ninto one dynamically allocated field.\n\nThis patch addresses an issue where SELinux was denying virtd access to the PCI\nconfiguration entries in sysfs. The lack of setxattr handlers for sysfs\nrequired that a single label be assigned to all entries in sysfs. Granting virtd\naccess to every entry in sysfs is not an acceptable solution so fine grained\nlabeling of sysfs is required such that individual entries can be labeled\nappropriately.\n\n[sds: Fixed compile-time warnings, coding style, and setting of inode security init flags.]\n\nSigned-off-by: David P.

While attempting to find whether a tcp\nsession is already existing, we were not checking whether the \"port\"\nused are the same. When a second mount is attempted with a different\n\"port\u003d\" option, it is being ignored. Because of this the cifs mounts\nthat uses a SSH tunnel appears to be broken.\n\nSteps to reproduce:\n\n1. create 2 shares\n# SSH Tunnel a SMB session\n2. ssh -f -L 6111:127.0.0.1:445 root@localhost \"sleep 86400\"\n3. ssh -f -L 6222:127.0.0.1:445 root@localhost \"sleep 86400\"\n4. tcpdump -i lo 6111 \u0026\n5. mkdir -p /mnt/mnt1\n6. mkdir -p /mnt/mnt2\n7. mount.cifs //localhost/a /mnt/mnt1 -o username\u003dguest,ip\u003d127.0.0.1,port\u003d6111\n#(shows tcpdump activity on port 6111)\n8. mount.cifs //localhost/b /mnt/mnt2 -o username\u003dguest,ip\u003d127.0.0.1,port\u003d6222\n#(shows tcpdump activity only on port 6111 and not on 6222\n\nFix by adding a check to compare the port _only_ if the user tries to\noverride the tcp port with \"port\u003d\" option, before deciding that an\nexisting tcp session is found. Also, clean up a bit by replacing\nif-else if by a switch statment while at it as suggested by Jeff.\n\nReviewed-by: Jeff Layton \u003cjlayton@redhat.com\u003e\nReviewed-by: Shirish Pargaonkar \u003cshirishp@us.ibm.com\u003e\nSigned-off-by: Suresh Jayaraman \u003csjayaraman@suse.de\u003e\nSigned-off-by: Steve French \u003csfrench@us.ibm.com\u003e\n" }, { "commit": "1b3859bc9e20d764316346665fc93ecea2d2b176", "tree": "9a643e0bf74d9b8339ae4bc45df1988ed306dc4d", "parents": [ "2920ee2b47fc8e6aebe1d1956b2725f48fa93cc5" ], "author": { "name": "Alexander Strakh", "email": "strakh@ispras.ru", "time": "Tue Sep 01 17:02:24 2009 +0000" }, "committer": { "name": "Steve French", "email": "sfrench@us.ibm.com", "time": "Tue Sep 01 17:02:24 2009 +0000" }, "message": "[CIFS] Memory leak in ntlmv2 hash calculation\n\n in function calc_ntlmv2_hash memory is not released.\n1.
