The problem appears to happen due to this race:\n\nsync/flush thread               xattr-set thread\n-----------------               ----------------\n\ndo_writepages                   ext4_xattr_set\next4_da_writepages              ext4_xattr_set_handle\nmpage_da_map_blocks             ext4_xattr_block_set\n        set DELALLOC_RESERVE\n                                ext4_new_meta_blocks\n                                        ext4_mb_new_blocks\n                                                if (!i_delalloc_reserved_flag)\n                                                        vfs_dq_alloc_block\next4_get_blocks\n\tdown_write(i_data_sem)\n        set i_delalloc_reserved_flag\n\t...\n\tup_write(i_data_sem)\n                                        if (i_delalloc_reserved_flag)\n                                                vfs_dq_alloc_block_nofail\n\n\nIn other words, the sync/flush thread pops in and sets\ni_delalloc_reserved_flag on the inode, which makes the xattr thread\nthink that it\u0027s in a delalloc path in ext4_new_meta_blocks(),\nand add the block for a second time, after already having added\nit once in the !i_delalloc_reserved_flag case in ext4_mb_new_blocks\n\nThe real problem is that we shouldn\u0027t be using the DELALLOC_RESERVED\nstate flag, and instead we should be passing\nEXT4_GET_BLOCKS_DELALLOC_RESERVE down to ext4_map_blocks() instead of\nusing an inode state flag.  We\u0027ll fix this for now with using\ni_data_sem to prevent this race, but this is really not the right way\nto fix things.\n\nSigned-off-by: Eric Sandeen \u003csandeen@redhat.com\u003e\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\nCc: stable@kernel.org\n"

      "message": "[PATCH] ext[34]: EA block reference count racing fix\n\nThere are race issues around ext[34] xattr block release code.\n\next[34]_xattr_release_block() checks the reference count of xattr block\n(h_refcount) and frees that xattr block if it is the last one reference it.\n Unlike ext2, the check of this counter is unprotected by any lock.\next[34]_xattr_release_block() will free the mb_cache entry before freeing\nthat xattr block.  There is a small window between the check for the re\nh_refcount \u003d\u003d1 and the call to mb_cache_entry_free().  During this small\nwindow another inode might find this xattr block from the mbcache and reuse\nit, racing a refcount updates.  The xattr block will later be freed by the\nfirst inode without notice other inode is still use it.  Later if that\nblock is reallocated as a datablock for other file, then more serious\nproblem might happen.\n\nWe need put a lock around places checking the refount as well to avoid\nracing issue.  Another place need this kind of protection is in\next3_xattr_block_set(), where it will modify the xattr block content in-\nthe-fly if the refcount is 1 (means it\u0027s the only inode reference it).\n\nThis will also fix another issue: the xattr block may not get freed at all\nif no lock is to protect the refcount check at the release time.  It is\npossible that the last two inodes could release the shared xattr block at\nthe same time.  But both of them think they are not the last one so only\ndecreased the h_refcount without freeing xattr block at all.\n\nWe need to call lock_buffer() after ext3_journal_get_write_access() to\navoid deadlock (because the later will call lock_buffer()/unlock_buffer\n() as well).\n\nSigned-off-by: Mingming Cao \u003ccmm@us.ibm.com\u003e\nCc: Andreas Gruenbacher \u003cagruen@suse.de\u003e\nCc: \u003clinux-ext4@vger.kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"
