[Bug 1289112] [NEW] UDF filesystem on USB stick is corrupted when creating file or directory with certain name

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

Ubuntu 13.10 amd64

I wiped a 32GB USB stick and created a UDF filesystem on it (as per
instructions at http://duncanlock.net/blog/2013/05/13/using-udf-as-an-
improved-filesystem-for-usb-flash-drives/ )

reading and writing works fine, until I try to create a directory or
file (using any method) with the exact name "Сергей Васильевич
Рахманинов - Piano Concertos Nos. 2 & 4 (Concertgebouw Orchestra feat.
piano: Vladimir Ashkenazy, conductor: Bernard Haitink)"

after attempting to create this file or directory, it appears to
succeed, but the name is truncated to "Сергей Васильев" and the
directory containing it on the UDF filesystem becomes unwritable and
undeletable, although it can still be read.

Initially came across this bug by copying a directory with this name
using nautilus, but also reproduced the problem with cp -r, mkdir and
touch.

Various parts of the name worked fine: "Сергей Васильевич Рахманинов"
seems fine as a filename, as is "Piano Concertos Nos. 2 & 4
(Concertgebouw Orchestra feat. piano: Vladimir Ashkenazy, conductor:
Bernard Haitink)". A much longer directory name also worked fine. So I'm
stumped as to what the problem is.

The filesystem was created with the command:
mkudffs -b 512 --media-type=hd --utf8 /dev/sdc
and otherwise seems to work fine.
