[pkg-apparmor] Bug#810888: bin.ping: does not let iputils-ping read /etc/libnl-3 or @{PROC}/@{pid}/net/psched

[Simon McVittie]

Package: apparmor-profiles
Version: 2.10-2
Severity: minor
Tags: patch

Please consider these new rules for /{usr/,}bin/ping:

  /etc/libnl*/** r,
  @{PROC}/@{pid}/net/psched r,

which address these AppArmor complaints:

Jan 13 11:18:03 perpetual kernel: [377675.445218] audit: type=1400 audit(1452683883.352:68): apparmor="ALLOWED" operation="open" profile="/{usr/,}bin/ping" name="/etc/libnl-3/classid" pid=2576 comm="ping" requested_mask="r" denied_mask="r" fsuid=1000 ouid=0

(I'm assuming that subsequent versions of libnl, a netlink library,
won't put sensitive information in /etc/libnl* either.)

The rule for psched can't use "owner" because fsuid != ouid.
