[Impact] 32 bit users experience corruption of large files. [Fix] A cast is needed when shifting the page's index. Colin and I independently identified the problem. It is a simple fix that has been merged upstream: http://git.kernel.org/linus/43b7c6c6a4e3916edd186ceb61be0c67d1e0969e [Test Case] Inside of an eCryptfs mount on an i686 Ubuntu install, create a file containing 4 GB + 1 page worth (4096 bytes) of zeros. Then inspect the file for non-zero bytes. $ rm zeros $ dd if=/dev/zero of=zeros bs=4096 count=$((4*1024*1024*1024/4096+4096)) 1052672+0 records in 1052672+0 records out 4311744512 bytes (4.3 GB) copied, 226.133 s, 19.1 MB/s $ hexdump -C zeros 00000000 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 101000000 The hexdump output should show all zeros. A non patched kernel will show non-zero bytes. [Original Bug Report] on extracting files with extracted size >4 GB files are getting currupted. interestingly file gets currupted in the very moment the file size gets more than 4GB.
