Those are known for taken their time to respond -- like we see here, as nothing happened for 10 days now.

A colleague of mine also tracked down a failed boot to the removal of the ntfs driver and reported seeing similar warnings with the ntfs3 driver. We're both accessing an NTFS partition on a Windows on Arm device, but it makes you wonder whether these warnings (corrections) are correct or indicative of a problem in the driver? Johan

Hi, Had a look at ntfs3 code and it is corrupting your volume. Every such message you are seeing is damaging a file or directory on your volume. I would personally suggest you modify your /etc/fstab to mount read-only. If it is getting simple things like this wrong who knows what else it is doing incorrect...

I fully agree and that's partly also why I asked Christian to make sure that the alias fs type is always mounted RO.

Hey Linus, A brief summary: The removal of the legacy ntfs driver has caused a regression for some users that rely on the legacy ntfs driver to be available during boot. The affected user here is Johan (Cc'ed). In addition he's seeing dmesg warnings that he didn't see before with the legacy ntfs driver. I see the following options to resolve this: (1) Since the ntfs3 driver is supposed to serve as a drop-in replacement for the legacy ntfs driver we should to it the same way we did it for ext3 and ext4 where ext4 registers itself also for the ext3 driver. In other words, we would register ntfs3 as ntfs3 filesystem type and as legacy ntfs filesystem type. To make it fully compatible we also need to make sure it's persistently mounted read-only. (2) We revert the ntfs driver (for now) as we are in the middle of the cycle. If you decide (2) is the right way to go then I would suggest we try the removal once more next cycle with the proposed change in (1) in place if you're up for that. Christian

My reaction to that is "only if it turns out we really need to". It sounds unlikely that somebody has an old ntfs setup and then tries to mount things rw which didn't use to work and things go sideways if that then suddenly works. But "unlikely" isn't "impossible", of course - it's just that I'd suggest we actually wait for that report to happen and ask what the heck they were doing and why they were doing that... Linus

It seems that ntfs3 has some bugs, and (according to Anton, the ntfs-classic maintainer) it's actually corrupting perfectly good filesystems. I'd expected that this kind of bug would have been shaken out by now (it's been in the kernel for over two and a half years!) but it seems like people just haven't been using it.

I think the "ntfs" alias must always be mounted read-only because you can currently have an fstab entry which does not specify "ro" and this mount would suddenly become writeable when updating to 6.9 (possibly by a non-privileged user, etc). We also need to do something about the ntfs3 driver spamming the logs about broken corrections also when mounted read-only even if it doesn't eat your filesystem then. And it seems write-support should be disabled in the driver by default until someone has tracked down why listing a directory can currently corrupt your filesystem. Johan

Well, it would be fairly easy to do particularly if we just do it for the old legacy case. Of course, even the legacy case had that CONFIG_NTFS_RW option, so people who depended on _that_ would want to be able to remount... Linus

Ah, right, I forgot about CONFIG_NTFS_RW as I've never enabled it. Judging from the now removed Kconfig entry perhaps not that many people did: The only supported operation is overwriting existing files, without changing the file length. No file or directory creation, deletion or renaming is possible. but I guess it still makes my argument above mostly moot. At least if we disable write support in ntfs3 by default for now... Johan

I think we can disable write support in ntfs3 for now. I've picked up the patch to make ntfs3 serve I sent some time ago that Johan tested now. The only thing left is to disable write support for ntfs3 as legacy ntfs driver for now. I took a stab at this. The following two patches I'm appending _should_ be enough iiuc. Johan, please take a look and please test. This is also available on: https://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs.git vfs.fixes So feel free to pull from there and look there as well.

I've picked up > the patch to make ntfs3 serve I sent some time ago that Johan tested > now. Note that I actually meant that write support should be disabled completely in ntfs3 for now. After this first encounter I have zero confidence in that driver and pushing people towards using it (by removing the old, read-only one) is just gonna result in further corrupted filesystems. At least make sure it can't modify anything by default and mark write-support as experimental and broken or something as that's apparently what it is. > The only thing left is to disable write support for ntfs3 as legacy ntfs > driver for now. I took a stab at this. The following two patches > I'm appending _should_ be enough iiuc. Johan, please take a look and > please test. I skimmed them and gave them a quick spin. It seems that not specifying either "ro" or "rw" in fstab now results in a ro mount, but I can still specify "rw" explicitly (in fstab or command line) and end up with: /dev/nvme0n1p3 on /mnt/windows type ntfs (rw,relatime,uid=0,gid=0,iocharset=iso8859-1) For obvious reasons, I did not dare listing the root directory or write anything, but it looks like it's not read-only. Using just my naive temporary hack from yesterday: diff --git a/fs/ntfs3/super.c b/fs/ntfs3/super.c index 8d2e51bae2cb..26be6c6d1032 100644 --- a/fs/ntfs3/super.c +++ b/fs/ntfs3/super.c @@ -1177,6 +1177,9 @@ static int ntfs_fill_super(struct super_block *sb, struct fs_context *fc) sb->s_xattr = ntfs_xattr_handlers; sb->s_d_op = options->nocase ? &ntfs_dentry_ops : NULL; + ntfs_warn(sb, "ntfs3 driver is broken, mounting read only"); + sb->s_flags |= SB_RDONLY; + options->nls = ntfs_load_nls(options->nls_name); if (IS_ERR(options->nls)) { options->nls = NULL; seems to prevent also explicit rw mounts (but judging from your patches it is not necessarily sufficient to prevent all modifications).

Are you sure there are no further issues here and that the patch is indeed correct? I did not test the patch, which is white-space damaged, but if it addresses also the remaining warnings then the commit message would need to be updated as well. Johan

This causes visible changes for users that rely on ntfs3 to serve as an alternative for the legacy ntfs driver. Print statements such as this should probably be made conditional on a debug config option or similar.
