Hi,

The risk of copy.fail on our infra is not very high, but we should patch
anyway.  The biggest risks are buildbot workers (they run semi-unstrusted
code from the package feeds) and webservices (where any vulnerability
would be escalated to root).  I haven't seen any sign of compromise.

I've just upgraded most of our infra with newer kernels with the fix:

- buildbot master
- buildbot workers (except 2 still pending because I/O is a bit slow)
- wiki
- forum
- git

Still pending:

- remaining buildbot workers - in progress
- main download server - planned tomorrow
- other services (firmware selector, sysupgrade server)
- misc infra servers
