[Bug 1665679] [NEW] agent socket path can easily get too long

[Iain Lane]

Public bug reported:

See

  http://comments.gmane.org/gmane.comp.encryption.gpg.devel/21073

When the path to the agent's socket is > 107 bytes long, it exceeds the
kernel's(?) size limit, and gpg-agent doesn't work.

This can quite easily happen in testsuites that create a fake home
directory and point GNUPGHOME into it. For example, this affects
devscripts and libgnupg-interface-perl currently. For the production
autopkgtest infrastructure, this only happens on s390x because that
happens to use the lxc backend to autopkgtest which creates slightly
longer paths for its home directories.

** Affects: gnupg (Ubuntu)
