Subject: Linux 2.6.23.8

We (the -stable team) are announcing the release of the 2.6.23.8 kernel.
It contains a few serious security fixes, as well as a raft of other
bugfixes and stuff from the last 2.6.23.1 kernel release.

Wait, what happened to versions 2.6.23.2 - 7 you might ask? Well, they
too are released, and I'll be responding to this message with those
individual changelogs and diffs. They corrispond to the different patch
groups that I sent out for review of the stable tree in order to handle
the huge number of overall patches. This way, if problems occur, it
will be easier for people to track down where the regression might have
happened.

I'll also be replying to this message with a copy of the patch between
2.6.23.7 and 2.6.23.8

The updated 2.6.23.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-2.6.23.y.git
and can be browsed at the normal kernel.org git web browser:
http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.23.y.git;a=summary

thanks,

Subject: Linux 2.6.23.3

We (the -stable team) are announcing the release of the 2.6.23.3 kernel.
It contains a number of bugfixes for a number of architecture specific
issues.

I'll also be replying to this message with a copy of the patch between
2.6.23.2 and 2.6.23.3

The updated 2.6.23.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-2.6.23.y.git
and can be browsed at the normal kernel.org git web browser:
http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.23.y.git;a=summary

thanks,

greg k-h

Subject: Linux 2.6.23.4

We (the -stable team) are announcing the release of the 2.6.23.4 kernel.
It contains a number of bugfixes for the core networking and wireless
code.

I'll also be replying to this message with a copy of the patch between
2.6.23.3 and 2.6.23.4

The updated 2.6.23.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-2.6.23.y.git
and can be browsed at the normal kernel.org git web browser:
http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.23.y.git;a=summary

thanks,

greg k-h

Subject: Linux 2.6.23.5

We (the -stable team) are announcing the release of the 2.6.23.5 kernel.
It contains a number of bugfixes for networking drivers.

I'll also be replying to this message with a copy of the patch between
2.6.23.4 and 2.6.23.5

The updated 2.6.23.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-2.6.23.y.git
and can be browsed at the normal kernel.org git web browser:
http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.23.y.git;a=summary

thanks,

greg k-h

Subject: Linux 2.6.23.6

We (the -stable team) are announcing the release of the 2.6.23.6 kernel.
It contains a number of bugfixes for drivers other than networking
(networking driver fixes were in 2.6.23.5).

I'll also be replying to this message with a copy of the patch between
2.6.23.5 and 2.6.23.6

The updated 2.6.23.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-2.6.23.y.git
and can be browsed at the normal kernel.org git web browser:
http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.23.y.git;a=summary

thanks,

greg k-h

So what is the magic command to apply this patch successfully?
It keeps rejecting the Documentation/ja_JP/HOWTO updates here.

Hammer GIT coders into sensibility to add proper MIME headers
on these patch post. Then, perhaps, things will just work.
(and postmaster won't get tons of rejects..)

What is the proper encoding for a patch that contains hunks in
multiple character sets?

GIT was only involved in creating the raw patch, which was then
compressed with gzip, then uncompressed and directly included in vim
into a raw email message when then mutt sent out.

So, if the mime headers were wrong on the patch that I sent out, it is
mutts fault, not git.

If you are trying to apply the patch directly from somewhere else, where
did it come from?

[.4, .5, .6 and .7 follows after .2 and .3]

I've seen the bunch of patches posted for review - split to several
series. But - out of curiocity - what's the reason to roll each
series into each own stable release? Can't all .2...7 be combined
into a single release (not counting .8 wich contains urgent security
fixes)? (I mean, not with already rolled out stuff, but the original
reasoning for split-releasing them (as opposed to split-reviewing))

Thanks.

That should only happen when we're fixing legacy crap to become UTF-8 --
and in that case, it's probably best to just handle it with a git-pull
rather than mailing patches around.

Normally, we should see only UTF-8 in patches.

Is there something "sacred" about version numbers that we need to be
stingy with them as they are a finite resource? :)

This way, we have specific, easy to identify points in the development
process to help users in case they report problems to let the developers
easily narrow down the potential problem.

That, and I couldn't think of some other way to name the -rc patches, so
I used the minor version number. Because of that, I was forced to name
the final releases with the same minor number to keep everyone sane over
time.

8-bit binary encoding, the same for single charset patch - we don't
want mail systems to change the encoding.
Unfortunately you can't display anything like that inline I think.
That means email may be unreliable in such cases (except maybe when
both sides use UTF-8 and the patch contains only UTF-8), git/ftp/etc.
will be fine.
