Hi all, I just sent of this new NTFS release 2.1.8 to Andrew and Linus for inclusion into the next 2.6 kernel release. At this point I would also like to say that I am no longer going to work on NTFS on 2.4 kernels as many of the write support changes to come as well as all the NFS changes from the 2.1.7 release are 2.6 kernel specific and backporting them to 2.4 kernels would take far too much time which I do not have. So if you want to keep up with the latest NTFS driver, I am afraid you will have to switch to a 2.6 kernel. Of course, other people (Pawel (-;) please feel free to provide backports if you wish... Here is the email I sent to Andrew and Linus: Hi Andrew, Hi Linus, please do a bk pull http://linux-ntfs.bkbits.net/ntfs-2.6 Thanks! This is the next NTFS release 2.1.8. It goes a long way towards ensuring the safety of people's data by refusing read-write mounts when the inode mirror or the journal are dirty and by emptying the journal when it is clean so Windows cannot cause data corruption by replaying a stale journal. Also, the new nano-second kernel time precision is used to improve on the NTFS <-> Linux time conversion functions. The detailed ChangeLog is in the descriptions of the ChangeSets below. Note the patch is rather large because of a lot of white space cleanups that happened while editing (removal of trailing spaces and conversion of spaces to tabs). This is tested with NTFS volumes with clean and dirty journals created by Win2k and XP and I am quite confident it will work with NT4 and Win2003 and later.

This is a little bit of a crude check in that we only look at the restart areas and not at the actual log records so that there will be a very small number of cases where we think that a volume is dirty when in fact it is clean. This should only affect volumes that have not been shutdown cleanly and did not have any pending, non-check-pointed i/o. <ai...@ca...> (04/05/07 1.1595) NTFS: Eeek. Forgot to revert the Makefile before checking it in last time... <ai...@ca...> (04/05/07 1.1597) NTFS: 2.1.8 release - If the $LogFile indicates a clean shutdown and a read-write (re)mount is requested, empty $LogFile by overwriting it with 0xff bytes to ensure that Windows cannot cause data corruption by replaying a stale journal after Linux has written to the volume. =================================================================== This is the simple GNU diff -urNp for non-BK users: I am not including the patch as it is far too big (165kiB) but you can find it here if you want it: http://www-uxsup.csx.cam.ac.uk/~aia21/linux/ The file is linux-2.6.6-rc3-bk-ntfs-2.1.8.diff or if you prefer a smaller file, linux-2.6.6-rc3-bk-ntfs-2.1.8.diff.bz2. |
