This patch allows us\nto supprot block sizes up to 256k, by using the low 2 bits to extend\nthe range of rec_len to 2**18-1 (since valid rec_len sizes must be a\nmultiple of 4).  We use the convention that a rec_len of 0 or 65535\nmeans the filesystem block size, for compatibility with older kernels.\n\nIt\u0027s unlikely we\u0027ll see VM pages of up to 256k, but at some point we\nmight find that the Linux VM has been enhanced to support filesystem\nblock sizes \u003e than the VM page size, at which point it might be useful\nfor some applications to allow very large filesystem block sizes.\n\nSigned-off-by: Wei Yongjun \u003cyjwei@cn.fujitsu.com\u003e\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n"

At worst,\nthings spin out of control.\n\nAs you might guess, we found a couple places in ext4 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\next4_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 ext4_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 ext4.\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"
