Dear Linux folks,
Using Debian Sid/unstable with 5.9.11 (5.9.0-4-686-pae), it looks like
the last `sudo grub-update` installed modules with corrupted file names.
`/boot` is mounted.

Checking the file system returned no errors.
$ sudo umount /boot
$ sudo fsck.ext4 /dev/md0
e2fsck 1.45.6 (20-Mar-2020)
boot: sauber, 331/124928 Dateien, 145680/497856 Blöcke
This causes GRUB fail to load the module, and it falls back into rescue
mode.
Any idea, what might have happened. It’s a degraded RAID, and I only use
one drive since several years, but never deactivated it, and `/dev/md0`
still shows up.
```
$ more /proc/mdstat
Personalities : [raid1] [linear] [multipath] [raid0] [raid6] [raid5]
[raid4] [raid10]
md0 : active raid1 sdb1[0]
497856 blocks [2/1] [U_]
md1 : active raid1 sdb2[0]
1953013952 blocks [2/1] [U_]
unused devices: <none>
```
Kind regards,
Paul

Well, the output dumpe2fs will tell us an awful lot about the file system. Whe was the last time the directory was OK?

Interesting. The file system was created in 2008. ;-) Please find the dumpe2fs output attached. > When was the last time the directory was OK? Do you know when it may > have gotten corrupted? The last reboot before. But I am really confused now though. $ ls -ld /boot/grub/i386-pc drwxr-xr-x 2 root root 28672 29.

Do you know hat that is? UTF-8?

But now, it gets really confusing. `last` claims, the system was running for four days. But that was not the (power was unplugged in between). I also can’t remember the shutdown failing in some strange way. In the systemd journal, it’s also recorded as one boot, but messages are missing, supporting it was powered off in between.

It's probably related to this problem, since a successful installation doesn't go down the RESTORE_BACKUP path which I think is the suspicious one here. > 2020-11-29 12:43:21 status installed grub-pc:i386 2.04-10 > […] > > So, afterward I was able to reboot without any issues.

Now that I look at it more closely, some of the changes to clean_grub_dir_real look suspicious: + char *srcf = grub_util_path_concat (2, di, de->d_name); + + if (mode == CREATE_BACKUP) + { + char *dstf = grub_util_path_concat_ext (2, di, de->d_name, "-"); + if (grub_util_rename (srcf, dstf) < 0) + grub_util_error (_("cannot backup `%s': %s"), srcf, + grub_util_fd_strerror ()); + free (dstf); + } + else if (mode == RESTORE_BACKUP) + { + char *dstf = grub_util_path_concat_ext (2, di, de->d_name); + dstf[strlen (dstf) - 1] = 0; + if (grub_util_rename (srcf, dstf) < 0) + grub_util_error (_("cannot restore `%s': %s"), dstf, + grub_util_fd_strerror ()); + free (dstf); + } + else + { + if (grub_util_unlink (srcf) < 0) + grub_util_error (_("cannot delete `%s': %s"), srcf, + grub_util_fd_strerror ()); + } + free (srcf); grub_util_path_concat is a helper that joins its arguments with "/"; grub_util_path_concat_ext does likewise except the last argument is appended as an extension without first appending "/". The first argument to both of these functions is "n": grub_util_path_concat expects n further argument, while grub_util_path_concat_ext expects n + 1 further arguments. So, in the RESTORE_BACKUP case, shouldn't that be: char *dstf = grub_util_path_concat (2, di, de->d_name); ... rather than grub_util_path_concat_ext? Otherwise it seems to me that it's going to try to append an additional argument which doesn't exist, and may well add random uninitialised stuff from memory. Running grub-install under valgrind would probably show this up (I can't get it to do it for me so far, but most likely I just haven't set up quite the right initial conditions). This looks more likely to be a userspace problem rather than filesystem corruption. I think this should likely be refiled as a bug against Debian's grub2 package. -- Colin Watson (he/him) [cjwatson@debian.org] ^ permalink raw reply [flat|nested] 12+ messages in thread

That corresponds with the 'i' in the code below: > Now that I look at it more closely, some of the changes to > clean_grub_dir_real look suspicious: > > + char *srcf = grub_util_path_concat (2, di, de->d_name); > + > + if (mode == CREATE_BACKUP) > + { > + char *dstf = grub_util_path_concat_ext (2, di, de->d_name, "-"); > + if (grub_util_rename (srcf, dstf) < 0) > + grub_util_error (_("cannot backup `%s': %s"), srcf, > + grub_util_fd_strerror ()); > + free (dstf); > + } ... however, if I'm understanding the code correctly, this is the codepath used to create the backup file (e.g., the previous version of boot.img). So shouldn't there be a "boot.img" file in /boot/grub/i386-pc which would be the newly installed version of that file, and so the system would actually be booting correctly? Or am I misunderstanding what is going on? Paul, I thought you said your system wasn't able to boot because the needed files in /boot/grub/i386-pc had apparently been corrupted? Essentially, there are three possibilities: 1) A hardware corruption which corrupted the directory. 2) A kernel bug which corrupted the directory. 3) The file system isn't actually corrupted, but the filename with the random garbage in the filename was created because a userspace application so requested it. The fact that all of the filenames have the a similar pattern of corruption to them would tend to rule out #1. And the fact that e2fsck didn't notice any other corruptions would tend to argue against #1 and #2. So #3 does seem to be the most likely. - Ted ^ permalink raw reply [flat|nested] 12+ messages in thread

So shouldn't there be a "boot.img" file in > /boot/grub/i386-pc which would be the newly installed version of that > file, and so the system would actually be booting correctly? Not quite. What's described here as "backup/restore" thing is used as follows: * rename old modules aside as a backup * do the rest of the installation (writing to the MBR or similar, as well as copying in new modules) * if installation succeeds, remove the backup files * if installation fails, then: * remove the newly-created modules * move the backup files back into place But if the restored file names are computed wrongly, then this leaves the system in a bad state as Paul described. I don't know why Dimitri chose to explicitly remove the new files first rather than just renaming over the top and then removing any leftovers at the end; that seems unnecessarily risky. Though this is code that's apparently supposed to work on Windows as well, and the MoveFile function that's used to implement grub_util_rename there requires the destination file not to exist (sigh), so maybe it had something to do with that. > Essentially, there are three possibilities: > > 1) A hardware corruption which corrupted the directory. > > 2) A kernel bug which corrupted the directory. > > 3) The file system isn't actually corrupted, but the filename with the > random garbage in the filename was created because a userspace > application so requested it. > > The fact that all of the filenames have the a similar pattern of > corruption to them would tend to rule out #1.
