Description j. alan eldridge 2001-04-24 11:35:41 EDT
See bug 38663 against RH7.1/e2fsprogs, or 35980 against RH-
Wolverine/e2fsprogs.

Mount has to read /proc/partitions in one gulp. It doesn't. Failed for me 
after a hard powerdown (oops) and the resulting fsck-the-world frenzy on 
startup, before the mount -a. Falure cause is identical (getting out of 
sync with the text at the 1K boundary), but failure mode not quite so 
drastic as it doesn't bail out like fsck does.

I'll attach a patch tonight when I get the time to put one together. This 
sucks, but we knew it was coming....

This problem also exists (in theory) in fdisk.c in util-linux-2.10r. Fdisk has 
another problem, too, that a quick glance at the source reveals: it never 
closes the FILE* it got to read /proc/paritions with. I'll submit that as a 
patch to util-linux with a note to see this bug or the e2fsprogs bug for 
details. 

I've left these as normal priority/severity. They may want to be escalated. 
It's a low frequency occurence bug, but the failure mode can be quite dramatic 
depending on the circumstances and the partition layout of the individual 
system affected.

Assigning to util-linux, where mount lives nowadays.

Fixed in util-linux-2.11n-3
