upgrading RH 9 system->Fedora with iso files and apt only
by Didier Casse
I have the yarrow's iso files on my HD in a RH9 system. Let's say I want
to upgrade selected packages using an "apt-get install" pointing to my
iso-mounted files, how do I do it?
i.e I mount the iso into some /mnt/yarrow1, /mnt/yarrow 2 etc..
Then what is the complete procedure to make my apt look into my own HD to
upgrade packages. Can anybody redirect me to the correct
resource or some literature hanging on the web? Thanks.
Assume also that I do not wish to burn CDs! I do not want to use
apt-cdrom. Thanks.
With kind regards,
Didier.

Expanding the list of "Hardened Packages"
by Dhiru Kholia
Hi,
This proposal was originally at https://fedorahosted.org/fesco/ticket/1104
(mitr asked me to move the discussion to fedora-devel to get more
attention and feedback)
...
http://fedoraproject.org/wiki/Hardened_Packages page mentions
that "FESCo requires some packages to use PIE and relro hardening by
default."
It would be great if this list could be expanded to include even more
packages which are at comparatively more risk of being exploited (locally
or remotely).
Such packages will typically include various system daemons, network
daemons and network enabled applications.
Lot of network daemons are already using PIE and RELRO (e.g. httpd,
MariaDB). So a natural question is why packages in same "network
daemons" class like PostgreSQL, Dovecot and MongoDB aren't being
hardened?
Some of the ways to implement this proposal are,
1. Hardening flags should be turned on (by default) for all packages
which are at comparatively more risk of being exploited or which meet
some well-defined criteria (suggestions welcome).
"Packaging Guidelines" say that "Other packages may enable the flags at
the maintainer's discretion."
Thinking from a security perspective, I find "Hardening flags can only
be disabled for other packages at the maintainer's discretion provided
enough justification is given to FESCo" to be more appropriate.
2. An alternate approach is to come up with an expanded list of packages
which should be hardened.
Any feedback is welcome!

Strange ssh / openldap linking problem
by Richard W.M. Jones
I'm not sure whether or not this is a bug, but it sure looks strange.
$ rpm -qf /usr/bin/ssh
openssh-clients-6.1p1-6.fc18.x86_64
$ ldd /usr/bin/ssh|grep ldap
libldap-2.4.so.2 => /lib64/libldap-2.4.so.2 (0x00007fad274fc000)
/usr/lib64/libldap-2.4.so.2 is a symbolic link to a symbolic link
which passes through a -devel package.
/usr/lib64/libldap-2.4.so.2 -> libldap.so # openldap-2.4.34-1.fc18
/usr/lib64/libldap.so -> libldap-2.4.so.2.9.0 # openldap-devel-2.4.34-1.fc18
/usr/lib64/libldap-2.4.so.2.9.0 is a real file # openldap-2.4.34-1.fc18
To cut a long story short, I fixed this by uninstalling openldap-devel
and reinstalling it. Now there is no -devel package in the chain:
$ ldd /usr/bin/ssh | grep ldap
libldap-2.4.so.2 => /lib64/libldap-2.4.so.2 (0x00007fe8caf69000)
/lib64/libldap-2.4.so.2 -> libldap-2.4.so.2.9.0
I'd like to understand how the original situation happened, because it
broke a supermin-built appliance (RHBZ#954185). I assume ldconfig
must have something to do with it. There is nothing unusual in the
%scripts of openldap (it just runs ldconfig as you'd expect), nor is
there any special openssh/openldap config file in /etc/ld.so.conf.d.
Rich.

F20 Self Contained Change: Snapshot and Rollback Tool
by Jaroslav Reznik
= Proposed Self Contained Change: Snapshot and Rollback Tool =
https://fedoraproject.org/wiki/Changes/Rollback
Change owner(s): Stephen Gallagher <sgallagh(a)redhat.com>, Colin Walters
<walters(a)redhat.com>
With the advent of thinly-provisioned LVM pools, it has become possible for us
to implement full-system LVM snapshotting for recording rollback points. We
are planning to support this for yum updates and eventually fedup upgrades
going forwards. This change request notes the addition of new tools provided
by the roller-derby project to present an interface and a CLI for managing and
initiating rollbacks.
== Detailed description ==
The roller-derby project will be providing a library and a CLI for creating,
labeling and managing LVM snapshots (plus non-LVM backups of /boot), oriented
primarily towards rpm-managed data, but useful beyond that. The yum plugin
"yum-plugin-fs-snapshot" will be updated to consume this library and save the
system state in a compatible format. The roller-derby CLI tool will provide an
interactive and scriptable interface for manipulating these snapshots and
determining when to remove older ones. It will also allow the tagging of
snapshots as "known-good", to be skipped when automatically-trimming for
space. The roller-derby project will likely provide a small daemon to keep
track of the available space in the LVM pool to proactively clean up snapshots
before the system runs out of space.
In order to prevent "loss" of data when rebooting into an snapshot, the
roller-derby CLI will allow saving a snapshot of the current state before
rolling back and will provide tools to allow mounting of that current state to
recover changes that have occurred since the rollback point.
== Scope ==
The scope of this project is the completion of the initial release of the
roller-derby project and the inclusion of thinly-provisioned LVM as an option
in the Anaconda installer [1].
Proposal owners: We need to complete the roller-derby project. Other than the
Anaconda change referenced above, all dependencies are available in Fedora
already.
Other developers: OS Installer Support for LVM Thin Provisioning
Release engineering: N/A (not a System Wide Change)
Policies and guidelines: N/A (not a System Wide Change)

Q: webfonts:
by Alec Leamas
Hi!
I'm trying to package a web application with bundled fonts. These fonts
are used by the web clients (browsers), and just served from the Fedora
webapp. The case is similar to javascript .js files.
Trying to package the webfonts as dependencies I have run into problem
together with my reviewer. Basically, we don't know what to do. Some
questions:
- Where should webfonts be stored? A specific dir would be good, since
some fonts exists in both a webfont and desktop variant with the same
filenames.
- How shoulld webapps get access to the system webfont? Is the apache
config file approach used for ..js files, where the webapp gets access
to specific system paths, usable also here?
- Given that the primary concern about fonts seems to be licensing, is
it really meaningful to unbundle them?
This is the short story. The somewhat longer:

Any help, out there?

Graphics driver support in F21+
by Adam Jackson
For F21, I plan to orphan the following X video drivers:
xorg-x11-drv-apm
xorg-x11-drv-cirrus
xorg-x11-drv-geode
xorg-x11-drv-glint
xorg-x11-drv-i128
xorg-x11-drv-i740
xorg-x11-drv-mach64
xorg-x11-drv-mga
xorg-x11-drv-neomagic
xorg-x11-drv-r128
xorg-x11-drv-rendition
xorg-x11-drv-s3virge
xorg-x11-drv-savage
xorg-x11-drv-siliconmotion
xorg-x11-drv-sis
xorg-x11-drv-tdfx
xorg-x11-drv-trident
Effectively this means that the graphics team will be focusing on KMS
for graphics support, with vesa and fbdev available as last-ditch
fallbacks. If anyone is interested in taking on support for these
chips, they're welcome to, though we would encourage anyone doing so to
work towards KMS support and not merely do "keep it building"
maintenance.
One other detail: the intel driver currently has both UMS support for
the i810 chipset, and KMS support for everything newer. To be
consistent with the above changes I'll be dropping the i810 support,
which will then fall back to vesa. Again, if someone wants to own the
i810 support, let me know and we can add you as a comaintainer.

Moving xine-lib and dependent apps to RPM Fusion Free for F17?
by Kevin Kofler
Hi,
the current xine-lib maintainer speaking. :-)
The Xine project:
http://www.xine-project.org/home
has recently released a new major version, version 1.2.0.
Unfortunately, among the list of changes:
http://sourceforge.net/projects/xine/files/xine-lib/1.2.0/README.txt.asc/...
there are these new "features":
* Use libavutil-provided implementations for CRC, SHA1 and BASE64 algorithms,
this makes use of libavutil even outside the FFmpeg decoding plugin,
but avoid duplication of algorithms between different plugins.
* Use av_mallocz() when xine_xmalloc_aligned() wouldn't be needed.
* FFmpeg is now required as an external dependency; if you want to build
xine-lib from source, please download a copy of FFmpeg from their SVN
server.
which basically mean that xine-lib now has a global, non-optional dependency
on FFmpeg's libavutil library.
So there are 4 possible ways forward:
(a) Stick with 1.1.x forever. I don't think that's a good idea in the long
run, upstream won't be providing security fixes for the old branch forever.
(b) Package libavutil (and only libavutil) from FFmpeg in Fedora. (I don't
think libavutil, as opposed to libavcodec, is actually patent-encumbered,
though that'd also have to be checked.) The issue there is that FFmpeg
upstream obviously doesn't support this. It would need some more black
packaging magic of the kind already done in xine-lib, and more legal
auditing. I don't think I want to investigate going down that road.
(c) Bundle parts or all of libavutil with xine-lib. Yuck!!!
(d) Move the whole thing (back) to RPM Fusion (where it originally was, before
we started needing xine-lib for Amarok and Phonon, which both no longer
use it). It would go to the Free section, of course.
My proposal is to go with (d).
The following packages currently depend on xine-lib:
* gxine
* (k9copy – already in RPM Fusion, not affected)
* kaffeine (my package, the reason why I maintain xine-lib in the first place)
* oxine
* xine-plugin
* xine-ui
These packages would have to move to RPM Fusion along with xine-lib.
In Kaffeine's case, upstream is switching from xine-lib to MPlayer in their git
repository, so it will likely have to move to RPM Fusion sooner or later
anyway. This means the affected packages are basically *xine*.
So my plan is to retire (for my packages, resp. have the respective maintainer
retire) the listed packages in Fedora for Fedora ≥ 17 and get (or have the
respective maintainer get) them into RPM Fusion Free instead. (I'd take care
of xine-lib and kaffeine myself, I hope the maintainers of the other packages
will take care of them.)
Comments? Objections?
