Bug#640934: libc6: flock() does not longer work in encfs-encoded directories

[Martin Ziegler <ziegler@email.mathematik.uni-freiburg.de>]

Package: libc6
Version: 2.13-18
Severity: important


After upgrading from 2.13-16 to 2.13-18, flock() stopped working
for files in encfs-encoded directories.

strace yields

open("foo", O_RDWR)           		= 3
flock(3, LOCK_SH)                       = -1 ENOSYS (Function not implemented)
