Was anything done about this?  Is it going to be left to luck that
anything bogus will eventually be noticed?  I'm not complaining (or
volunteering), but I'd like to know if there is any peace-of-mind

Not that I know of.

Probably.  It's free software maintained by a bunch of volunteers on
their free time, so unless you are willing to volunteer, there's no
sense in nagging.

I tried to make it clear that I am not nagging.  That's why I wrote

I'm just trying to find out what the situation is--e.g., whether there
is some off-list work being done.  Thank you for your assessment of
the situation.  If anyone has further information, I'd be most
grateful to hear about it.

Oh, come on.  Stop everybody crying "sacrilege".  Emacs is a large
executable and an operating environment for many.  The question is
quite relevant, even though we might not like its current answer.

There is nothing wrong in trying to assess the current situation by
asking on the developers' list.  Where else would you go for that?

it's relevancy is not under debate.  i'm just curious what concrete
action will come of it (particularly as initiated and enacted by the
OP), besides all this talk, entertaining as it may or may not be.  if
you feel defensive then please just try to relax -- i'm not asking you,
specifically, or even "you" generally.

Nobody has offered as yet to take charge of verification.
Alas, I cannot possibly do it myself.

Ok, I'll volounteer to keep track of what's verified so far.


If you want to participate in the verification, pls download
the changeset tarball as previously announced.

Then send me a list of the files you want to verify (C code or Lisp),
or just request a list of files to check (and I'll chose some files
for you).

I will then respond directly to you with a unique key which you must
later return to me when you have complete validation of those files.

Do NOT copy your request to emacs_devel!!

I will post regular updates on the progress of the verification.

Note:  There is a total of approx 2250 files/revisions to check,
       so I will not post the entire list here.  I can send it
       to you on demand.

My idea was that we would ask the various contributors to check the
changes they installed.  It doesn't have to be done that way; we
can try it this way too.

I don't know whether it's useful, but I've been tracking the emacs CVS
sources with my arch branch since before the break-in.

Naturally, any bogus checkins to CVS would have been mirrored in the arch
branch as well, but perhaps it might serve as check against retro-active
modification of the CVS files on savannah.

The intruder could have _also_ modified the arch archive to match[*] -- they
are now gpg-signed, but unfortunately were not at the time of the incident --
but that seems a fair bit less likely.  In addition, the archive has been
mirrored on a non-GNU host since 1-sept (and arch mirrors are essentially
append-only); however there's still a (small) avenue for compromise, even
with the mirror, as I have an ssh key for it stored on fencepost.

Any checks you can make to improve confidence would be good, but if
bogus checkins are mirrored too, I don't really see how it can help us.

But a raw compare of the tip of CVS and arch would be inteseting.

I don't recall, so is the arch archive just a mirror of CVS, or
is it two ways (i.e. will changes to arch propagates back to CVS) ?

If the latter is the case, who has access to your arch archive,
and how do you control that access?

It's two-way.

It's my archive, so of course I control what goes into it (the same way you'd
control any files on unix).  Inter-archive merging in arch is usually `pull'
based, so if I wanted to merge changes from someone elses branch, I'd have to
explicitly do so -- in a way it's similar to applying patches someone sends
to the mailing list, just more convenient and with better record-keeping.

The remote mirrors on non-GNU machines, OTOH, _are_ just mirrors; of course
now that everything's signed I'd have no qualms about using them to restore
the master fencepost copy if something horrible happened.

    Naturally, any bogus checkins to CVS would have been mirrored in the arch
    branch as well, but perhaps it might serve as check against retro-active
    modification of the CVS files on savannah.

This could be very useful.  If you can verify that the check-ins
recorded in CVS with dates before the crack occurred are the same as
you put in your arch archive, that would be enough to show they are
ok.  That might do more than half the job right there.

I think it is unlikely the cracker found your mirror.

      In addition, the archive has been
    mirrored on a non-GNU host since 1-sept (and arch mirrors are essentially
    append-only); however there's still a (small) avenue for compromise, even
    with the mirror, as I have an ssh key for it stored on fencepost.

Do you have backups for the mirror?  If so, you could check
the mirror against its backups to verify that things were not
altered subsequently.

Emacs diffs are now ready for verification.

Re: What shall we do to verify the CVS diffs for emacs?

[Richard Stallman]

It would be very useful for someone to take overall charge of the
verification activity--to make sure that at least the important files
do get checked.  I can't do it myself, though; I don't have time.
(Since my elbow broke, I have barely been able to work on Emacs at
all.)

Can someone volunteer to do this?
