Who is broken when hotplug,udev and hal are causing high cpu load?
by dragoran
I bought a new card usb2 card reader. Sometimes when I plug a sd card
into it all hotplug programs cause 60-80% cpu load and nothing happens
(no mount) sometimes it just works.
I want to fill this into bugzilla but dunno against what?
When this happens dmesg reports many Buffer I/O erros.

fork bomb attack
by Florin Andrei
http://www.securityfocus.com/columnists/308?ref=rssdebia
Quotes:
"I wrote up a very simple bourne shell script on my work machine, which
runs Mandrake Linux, and executed it under my non-privileged account.
Within seconds, the machine was brought to its knees -- totally crippled
and unusable. I stared at my screen in disbelief for a few moments,
totally stunned with what had just happened."
"I then proceeded to fork bomb every Unix machine I could get my hands
on. My FreeBSD server at home shrugged it off (even after inviting other
connected users to try), as did my OpenBSD gateway. This, too, is
exactly what I expected to happen."
"Next, I asked several my associates who use Linux to try it out on
their machines, and we didn't have to go far to find more Linux
distributions that succumbed to the same painfully effective fork bomb
attack. Both Gentoo and Red Hat followed in the footsteps of Mandrake,
and each died quicker than you can say "unreasonable default settings."
I'll quickly mention here that Debian did not suffer the same fate as
the others; congrats to the Debian development team."
"For the record, I hope that anyone out there running Linux is just as
surprised as I was that this ancient attack still works on the default
installation of so many high profile Linux distributions. I personally
don't understand how usability can supersede security when the
consequences are so grave."

Bugzilla Target for Rawhide
by Roland Käser
Hi all
First of all: Congratulations for the FC4 Relase. I downloaded it and
tried something with it. This probably the best Redhat (Fedora) release
ever.
It contains still some bugs I whould like to post. But on the bottom
line it looks very good. Special the xen and gfs I'm currently testing
(only xen) can become our company internal core technology for failover.
Many thanks
Roland Käser

AntiVirus?
by Naheem Zaffar
Since Fedora is supposed to be a general purpose OS, are there any
plans to add any type of AV software?
I know that virii are not big problems in the linux world, but its
better to be prepared (after if linux gets the penetration, attempts
will be made...)
There is a list of Linux A/V (GPL and commercial) on this site:
http://www.linux.org/apps/all/System/Anti-Virus.html
However all of the GPL A/V are console based, but one should be chosen
as a default install IMO.
(which one is probably a packaging-list discussion, however the wider
discussion on antivirus software also needs to be addressed, and this
IMO is the place.)

fc4test1 bugs
by Joe Desbonnet
Is it acceptable to report fc4test1 bugs here or should they go
straight into bugzilla? Two things I noticed while installing:
Trying to install from ISO images on local HDD option failed. I tried
with an external USB drive and then an IDE drive. It failed to find
the images on both occasions (yes I'm sure I got the path correct).
Also: it would be nice to be able to specify the network port for the
HTTP install option. Right now it assumes port 80.
Like a previous post today, it would be really, really nice to be
able to install on a USB drive without having to make new initrds etc.

RFC: rpm auto-glib version enforcement
by Warren Togami
# Require Binary Compatible glib
%define glib_ver %(pkg-config --modversion glib-2.0 | cut -d. -f 1,2)
Requires: glib2 >= %{glib_ver}
I added this to gaim.spec a while ago because users were installing
rawhide gaim compiled against glib2-2.6.x on FC3, which has glib2-2.4.x.
gaim was then crashing because:
1) applications compiled against a newer glib are not backwards ABI
compatible. AFAIK glib is supposed to be only forward ABI compatible. [1]
2) glib does not use verisoned so names
3) so rpm auto-dep cannot enforce compatible glib ABI version
# Require Binary Compatible glib
%define glib_ver %(pkg-config --modversion glib-2.0 | cut -d. -f 1,2)
Requires: glib2 >= %{glib_ver}
What the above spec chunk does is read the pkgconfig file contained in
glib2-devel, and cut out the the major and minor version. That version
is used to make an artificial RPM dependency on glib versions that are
supposed to be ABI compatible with the package.
While it is totally unsupported for a user to install packages from
newer distributions on older distributions, they do it anyway. It
causes upset feelings, confusion, and a waste of time with bogus
reports. But there may be a simple and robust way to automate and avoid
this problem.
Proposal:
RPM (via redhat-rpm-config?) should implicitly add something like the
above spec blob in order to enforce glib ABI dep, but *only* if the
binary payload actually links to glib.
Thoughts?
Is this feasible to implement in a clean way?
Will this fail in any corner cases?
[1]
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=149190
This is unrelated to the above RFC, but if I understand this correctly,
glib2-2.6 g_stat() changed in such a way that breaks ABI forward compat.
Somebody that knows glib better can verify or explain this? Or maybe
it was already fixed upstream.

Status of USB install support in FC4 Test1?
by Bernd Bartmann
Hi,
what's the status in FC4 Test1 for install support to USB storage
devices. FC3 only seems to allow installation to USB storage devices
in expert mode and even then you have to manually created an initrd
with support for the USB storage modules. Is there any progress in
this area planned for FC4?
Thanks in advance,
Bernd.

gimp-2.2.4-0.fc3.3 man pages
by susan_geller@speakeasy.net
It looks like the man pages intalled with gimp have somewhat unusual names:
$ rpm -ql gimp | grep /usr/share/man
/usr/share/man/man1/gimp-2.2.1.gz
/usr/share/man/man1/gimp-remote-2.2.1.gz
/usr/share/man/man1/gimptool-2.0.1.gz
/usr/share/man/man5/gimprc-2.2.5.gz
So you have to say:
$ man gimp-2.2
Instead of just:
$ man gimp
Has anyone considered adding commands like:
$ ln -s /usr/share/man/man1/gimp-2.2.1.gz /usr/share/man/man1/gimp.1.gz
to the rpm post install script?
Thanks,
Susan
