      "message": "ext34: ensure do_split leaves enough free space in both blocks\n\nThe do_split() function for htree dir blocks is intended to split a leaf\nblock to make room for a new entry.  It sorts the entries in the original\nblock by hash value, then moves the last half of the entries to the new\nblock - without accounting for how much space this actually moves.  (IOW,\nit moves half of the entry *count* not half of the entry *space*).  If by\nchance we have both large \u0026 small entries, and we move only the smallest\nentries, and we have a large new entry to insert, we may not have created\nenough space for it.\n\nThe patch below stores each record size when calculating the dx_map, and\nthen walks the hash-sorted dx_map, calculating how many entries must be\nmoved to more evenly split the existing entries between the old block and\nthe new block, guaranteeing enough space for the new entry.\n\nThe dx_map \"offs\" member is reduced to u16 so that the overall map size\ndoes not change - it is temporarily stored at the end of the new block, and\nif it grows too large it may be overwritten.  By making offs and size both\nu16, we won\u0027t grow the map size.\n\nAlso add a few comments to the functions involved.\n\nThis fixes the testcase reported by hooanon05@yahoo.co.jp on the\nlinux-ext4 list, \"ext3 dir_index causes an error\"\n\nThanks to Andreas Dilger for discussing the problem \u0026 solution with me.\n\nSigned-off-by: Eric Sandeen \u003csandeen@redhat.com\u003e\nSigned-off-by: Andreas Dilger \u003cadilger@clusterfs.com\u003e\nTested-by: Junjiro Okajima \u003chooanon05@yahoo.co.jp\u003e\nCc: Theodore Ts\u0027o \u003ctytso@mit.edu\u003e\nCc: \u003clinux-ext4@vger.kernel.org\u003e\nCc: \u003cstable@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

Then I\u0027ve found that ext3_read_inode() can call\nmake_bad_inode() without any error/warning messages, for example in the\nfollowing case:\n\n...\n        if (inode-\u003ei_nlink \u003d\u003d 0) {\n                if (inode-\u003ei_mode \u003d\u003d 0 ||\n                    !(EXT3_SB(inode-\u003ei_sb)-\u003es_mount_state \u0026 EXT3_ORPHAN_FS)) {\n                        /* this inode is deleted */\n                        brelse (bh);\n                        goto bad_inode;\n...\n\nBad inode can live some time, ext3_unlink can add it to orphan list, but\next3_delete_inode() do not deleted this inode from orphan list.  As result\nwe can have orphan list corruption detected in ext3_destroy_inode().\n\nHowever it is not clear for me how to fix this issue correctly.\n\nAs far as i see is_bad_inode() is called after iget() in all places\nexcluding ext3_lookup() and ext3_get_parent().  I believe it makes sense to\nadd bad inode check to these functions too and call iput if bad inode\ndetected.\n\nSigned-off-by:\tVasily Averin \u003cvvs@sw.ru\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

At worst,\nthings spin out of control.\n\nAs you might guess, we found a couple places in ext3 where things spin out\nof control :)\n\nFirst, we had a corrupted directory that was never checked for\nconsistency...  it was corrupt, and pointed to another bad \"entry\" of\nlength 0.  The for() loop looped forever, since the length of\next3_next_entry(de) was 0, and we kept looking at the same pointer over and\nover and over and over...  I modeled this check and subsequent action on\nwhat is done for other directory types in ext3_readdir...\n\n(adding this check adds some computational expense; I am testing a followup\npatch to reduce the number of times we check and re-check these directory\nentries, in all cases.  Thanks for the idea, Andreas).\n\nNext we had a root directory inode which had a corrupted size, claimed to\nbe \u003e 200M on a 4M filesystem.  There was only really 1 block in the\ndirectory, but because the size was so large, readdir kept coming back for\nmore, spewing thousands of printk\u0027s along the way.\n\nPer Andreas\u0027 suggestion, if we\u0027re in this read error condition and we\u0027re\ntrying to read an offset which is greater than i_blocks worth of bytes,\nstop trying, and break out of the loop.\n\nWith these two changes fsfuzz test survives quite well on ext3.\n\nSigned-off-by: Eric Sandeen \u003csandeen@redhat.com\u003e\nCc: \u003clinux-ext4@vger.kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
