Package: mount
Version: 2.12r-19
Severity: normal
I have several identical Debian unstable machines in my office.
A user reported not being able to mount his USB flash drive on one of
these machines, while it was working fine on the other two. This didn't
make any sense at first because all three machines are identically
configured, running the exact same versions of all packages and the same
kernels, etc.
Digging into things further, I found that the only problem was
when running a mount command as a normal user where the fstype in
/etc/fstab was set to auto. I have the following pertinent lines in
/etc/fstab on all three machines:
---
/dev/sdb1 /mnt/usb auto defaults,rw,user,noauto 0 0
/dev/sdb1 /mnt/vfat vfat defaults,rw,user,noauto 0 0
---
Note that running 'mount /mnt/vfat' worked fine on the problem machine,
but not 'mount /mnt/usb'. The latter would result in the mount command
blocking or hanging and eating up 100% of the CPU indefinitely.
Interestingly enough, based on what I discovered below finally, running
the 'mount /mnt/usb' as root works fine. Given the data below, I'm not
sure why exactly.
So I finally figured out how to strace mount using sudo since
normally mount won't let you strace it without the assistance of sudo.
I have attached all the relevant files on two machines. monkey is the
name of the machine which is not working properly. lemur is the name of
one machine which is working fine.
The only real difference I finally found between the two
machines is in /etc/blkid.tab. If I replace the version found on monkey
with the one found on lemur, or just zero out the version found on
monkey entirely, then 'mount /mnt/usb' as a normal user works. So I
assume that the original version as found on monkey was somehow corrupt?
But then I don't understand exactly why running the same command worked
as root but not as a normal user. Maybe the code path through mount is
different enough running as root that a problem in this file wouldn't
cause the same issue when running as root.
Anyway, I'm attaching the strace from monkey and lemur, along
with the versions of the blkid.tab file which existed initially on both
machines. Like I said, as soon as I either zero out the file or replace
it with a slightly different version, then the mount command works fine.
Either way, this seems like a bug in mount since data in this file
shouldn't prevent an otherwise perfectly normal and workable mount
request from failing.
Let me know if you need any more data on this.
