Hello,
$ settrans -afg shadow shadowfs $PWD
(yes, in this case, it should be possible to cd
shadow/shadow/shadow...)
The problem was that shadowfs had the root node 'shadow' looked while
it also tried to _lookup_ the root node 'shadow' - result: deadlock.
The root node was different then all other nodes in shadowfs, because
this was the only 'static' node. All other nodes were created
on-the-fly during a lookup.
I got the idea to check at the beginning of netfs_S_dir_lookup()
wether the user wants to lookup something in the root node and if that
is the case to simply 'copy' the root node and use the copy for
further work. Then, the real root node would only be used as a
'template'. Locking would be done on the newly created node and there
wouldn't be deadlocks anymore.
Is that an acceptable solution for this locking problem or are there
better approaches?
Thanks,
moritz
