Permissions set incorrectly when copying

[Ken Sharp]

Recently, probably following a dist-upgrade, the permissions have been getting munged when copying over sshfs.

SERVER (VFAT):

$ ll
total 36M
d---rwxr-x 1 ken 1015 32K Jul 27 01:27 ./
drw-rwxr-x 1 ken 1015 32K Jul 26 22:11 ../

CLIENT (/tmp)

$ ll
total 36M
drwxrwxr-x 5 ken ken 4.0K Jul 29 11:54 ./

drw-rwxr-x 2 ken ken 4.0K Jul 29 11:54 20130726T220222-15fps/
-rw-rwxr-x 1 ken ken 4.3M Jul 29 11:54 20130726T220222-15fps.mp4*

The result being that I cannot access 20130726T202957-15fps which contains ~500 files.

I don't know why this has started happening but around the same time smbfs has problems connecting and copying (from a different server - ext4) and boot fails because nofail is being ignored. Something core must have been changed.

And I've just found out that the first few files that have been copied into this directory are also inaccessible:

If I didn't have sudo access I'd be screwed.

Worse than I thought. I've attached an ll -R of the full tree. Note that I have already corrected the permission on the files I mentioned above.

This is insane and never used to occur!

[Ken Sharp (kennybobs)]

Brand new install of 12.04.3 and nothing has changed.

$ chown -R ken:ken 20131119T070551-15fps
chown: cannot read directory `20131119T070551-15fps': Permission denied

[Ken Sharp (kennybobs)]

This is bloody hideous!!!

$ sudo chmod -R a+rw 20131119T070551-15fps
$ cd 20131119T070551-15fps/
bash: cd: 20131119T070551-15fps/: Permission denied
