Bugzilla Bug 77692

for example in /etc/fstab i have such line:
LABEL=DATA               /mnt/data       vfat            iocharset=koi8-r,codepage=866,nouser,nosuid,rw,umask=002,gid=100,showexec 0 0

with old util-linux all will fine, but 
now I get this:
# mount /mnt/data/
mount: special device LABEL=DATA does not exist

Reproducible: Always
Steps to Reproduce:
1.KEYWORD="~x86" emerge util-linux
2.
3.

*** Bug 77693 has been marked as a duplicate of this bug. ***

you neglected to post `emerge info` like the bug report page told you to

also, could you please run `emerge util-linux >& log` and post the 'log' file as an attachment ?

My apologies. I post three bug posts in one day, and on third time,
fogot to post emerge info

I don't know how it help,
may be you want /etc/fstab?

it seems that only vfat labels are broken atm ... e2fsprogs bug really

could you try e2fsprogs-1.36-r1 ?

>could you try e2fsprogs-1.36-r1 ?

Nothing change.

Realy strange that I have in /etc/fstab two lines like this:

/dev/sda5               /mnt/data       vfat            iocharset=koi8-r,codepage=866,nouser,nosuid,rw,umask=002,gid=100,showexec 0 0

LABEL=TEMP               /mnt/tmp       vfat            iocharset=koi8-r,codepage=866,nouser,nosuid,rw,umask=002,gid=100,showexec 0 0

in second line LABEL works fine,
but if I change /dev/sda5 to
LABEL="it's name"
in case of 
mount /mnt/data
I get that there no partition with such label
in case of
mount -a
I get segmentation fault

what version of util-linux ?  2.12q should have the segfault fixed ...

>what version of util-linux ?  2.12q should have the segfault fixed ...

make ACCEPT_KEYWORDS="~x86"

and emerge util-linux, this help with segfault.

but if earlier this work


>LABEL=TEMP               /mnt/tmp       vfat            iocharset=koi8-r,codepage=866,nouser,nosuid,rw,umask=002,gid=100,showexec 0 0

now mount say that it can not find partiotion with label TEMP

forgive my ignorance, but ive never done labels before ... how do you generate
labels for your vfat partitions (so that i can reproduce / test / etc... over
here) ?

>forgive my ignorance, but ive never done labels before ... how do you generate labels for your vfat >partitions (so that i can 
>reproduce / test / etc... over here) ?

man mkfs.vfat

-n volume-name
              Sets the volume name (label) of the filesystem.  The volume name
              can be up to 11 characters long.  The default is no label.

I can't reproduce this at all.
Tested using util-linux-2.12p or util-linux-2.12q.
And e2fsprogs-1.35-r1 and e2fsprogs-1.36-r[23]

mkfs.vfat -F 32 -n FATTEST -v /dev/md/7
mkdir -p /tmp/fattest
blkid -t LABEL=FATTEST 
(show /dev/md/7 as the location)
mount LABEL=FATTEST /tmp/fattest
(mounts perfectly fine)
umount /tmp/fattest

echo "LABEL=FATTEST /tmp/fattest auto defaults 0 0" >>/etc/fstab
mount /tmp/fattest
(mount works perfectly fine)
umount /tmp/fattest

>I can't reproduce this at all.

$blkid -t LABEL=TEMP
/dev/sda6: UUID="F467-4E0E" TYPE="vfat" LABEL="TEMP"

$ mount LABEL=TEMP /mnt/tmp/
mount: special device LABEL=TEMP does not exist

$ mount /dev/sda6 /mnt/tmp/
all fine

and addition info
$qpkg -i -I util-linux
sys-apps/util-linux-2.12q *

$mkdir /tmp/test
$cd /tmp/test
$tar xzvf /usr/portage/distfiles/util-linux-2.12q.tar.gz
$ cd util-linux-2.12q/
$ ./configure && make
$/mount/mount LABEL=TEMP /mnt/tmp/
all fine
$umount /mnt/tmp
$mount LABEL=TEMP /mnt/tmp
mount: special device LABEL=TEMP does not exist

so as I can understand all problems in patches

I made some investigations,
and find out that "vfat lables" can be two types:
1)part of "vfat superblock"
2)file in root directory with attribute "volume label"

e2fsprogs 1.38 support only the first type.

current development version of e2fsprogs support the first and  the second type.

This ability required changing only a couple of lines in e2fsprogs

Here is patch for ebuild:

patch for e2fsprogs in attachment

Created an attachment (id=74886) [edit]
add ability to read vfat labels for every type of "vfat partition" 

added to 1.38-r1, thanks
