90. By Andrey Bondarenko on 2012-11-12

* debian/patches-applied/parse_userenv_as_envfile: user_envfile is parsed as an env
  file instead of parsing it as a conffile which has different syntax.
  see: https://fedorahosted.org/pipermail/pam-developers/2011-June/thread.html#75
* Pull changes from 1.1.3-2ubuntu2.1. Remaining changes:
  - debian/patches-applied/parse_userenv_as_envfile: user_envfile is parsed
    as an env file instead of parsing it as a conffile which has different
    syntax.
* Merge changes from 1.1.2-2ubuntu8.3 and 1.1.2-2ubuntu8.2+abone1.
* SECURITY REGRESSION:
  - debian/patches/security-dropprivs.patch: updated patch to preserve
    ABI and prevent daemons from needing to be restarted. (LP: #790538)
  - debian/patches/autoconf.patch: refreshed
* debian/patches-applied/parse_userenv_as_envfile: user_envfile is parsed
  as an env file instead of parsing it as a conffile which has different
  syntax.
* SECURITY UPDATE: multiple issues with lack of adequate privilege
  dropping
  - debian/patches/security-dropprivs.patch: introduce new privilege
    dropping code in libpam/pam_modutil_priv.c, libpam/Makefile.*,
    libpam/include/security/pam_modutil.h, libpam/libpam.map,
    modules/pam_env/pam_env.c, modules/pam_mail/pam_mail.c,
    modules/pam_xauth/pam_xauth.c.
  - CVE-2010-3430

  - CVE-2010-4707

  - debian/patches/CVE-2010-3853.patch: use clean environment in
    modules/pam_namespace/pam_namespace.c.
  - CVE-2010-3853
* debian/patches-applied/series: disable hurd_no_setfsuid patch, as it
  isn't needed for Ubuntu, and it needs to be rewritten to work with the
  massive privilege refactoring in the security patches.
* debian/patches-applied/update-motd: santize the environment before
  calling run-parts, LP: #610125

No-change rebuild with gzip 1.4-1ubuntu2 to get multiarch-clean
compression of manpages. LP: #871083.

87. By Steve Langasek on 2012-01-28

* Merge from Debian unstable, remaining changes:
  - debian/libpam-modules.postinst: Add PATH to /etc/environment if it's
    not present there or in /etc/security/pam_env.conf. (should send to
    Debian).
  - debian/libpam0g.postinst: only ask questions during update-manager when
    there are non-default services running.
  - debian/libpam0g.postinst: check if gdm is actually running before
    trying to reload it.
  - debian/libpam0g.postinst: the init script for 'samba' is now named
    'smbd' in Ubuntu, so fix the restart handling.
  - Change Vcs-Bzr to point at the Ubuntu branch.
  - debian/patches-applied/series: Ubuntu patches are as below ...
  - debian/patches-applied/ubuntu-rlimit_nice_correction: Explicitly
    initialise RLIMIT_NICE rather than relying on the kernel limits.
  - debian/patches-applied/pam_umask_usergroups_from_login.defs.patch:
    Deprecate pam_unix' explicit "usergroups" option and instead read it
    from /etc/login.def's "USERGROUP_ENAB" option if umask is only defined
    there. This restores compatibility with the pre-PAM behaviour of login.
  - debian/patches-applied/pam_motd-legal-notice: display the contents of
    /etc/legal once, then set a flag in the user's homedir to prevent
    showing it again.
  - debian/update-motd.5, debian/libpam-modules.manpages: add a manpage
    for update-motd, with some best practices and notes of explanation.
  - debian/patches/update-motd-manpage-ref: add a reference in pam_motd(8)
    to update-motd(5)
  - debian/local/common-session{,-noninteractive}: Enable pam_umask by
    default, now that the umask setting is gone from /etc/profile.
  - debian/local/pam-auth-update: Add the new md5sums for pam_umask addition.
  - Build-depend on libfl-dev in addition to flex, for cross-building
    support.

* Dropped changes, included in Debian:
  - debian/patches-applied/update-motd: set a sane umask before calling
    run-parts, and restore the old mask afterwards, so /run/motd gets
    consistent permissions.
  - debian/patches-applied/update-motd: new module option for pam_motd,
    'noupdate', which suppresses the call to run-parts /etc/update-motd.d.
  - debian/libpam0g.postinst: drop kdm from the list of services to
    restart.
* Build-depend on libfl-dev in addition to flex, for cross-building

[ Steve Langasek ]
* debian/patches/pam_motd-legal-notice: use pam_modutil_gain/drop_priv
