Emacs 24.0.93 Pretest Windows Binaries published

[Christoph Scholtes]

The Emacs 24.0.93 Pretest Windows Binaries have been published in

http://alpha.gnu.org/gnu/emacs/pretest/windows/

The binaries were built using the following libraries:
giflib-4.1.4-1
gnutls-3.0.9
jpeg-6b-4
libXpm-3.5.8
libpng-1.4.3-1
tiff-3.8.2-1
zlib-1.2.5-2

Pre-built Windows binaries for GnuTLS are available at this location:
http://sourceforge.net/projects/ezwinports/files/

See the file included README.W32 file for more information on how to 
obtain other binaries necessary to make use of certain Emacs features.

Please report any bugs that you come across via M-x report-emacs-bugs,
or email bug-gnu-emacs@gnu.org.

For questions, email emacs-devel@gnu.org.

Can you say what that means?  What is GnuTLS for, and why might an Emacs user
want to obtain a binary for it?  How does it relate to Emacs?

It's an email authentication package.  See the node "Authentication"
in the smtpmail manual that comes with Emacs.

The point was for you to say that _in the announcement email_.

It doesn't make much sense, in an email about "Pretest Windows Binaries", to
provide a link to something that is separate and different from "Pretest Windows
Binaries", without saying anything about what that link is for.

Sure, users can always google "GnuTLS", but they should not have to.

Please add a one-line description to the link that is provided.  Preferably,
_link_ that description to a page with more info (e.g. GNU page or Wikipedia
page for GnuTLS).

Then make your point explicitly.  For some weird reason I thought you
actually wanted to know the answer, and made an effort of looking for
an providing a reference for you to read about that.

I replied to the _announcement_ mail and its author, requesting that it describe
GnuTLS.

Your questions requested nothing about the announcement.  They were
questions about GnuTLS.

This is an announcement email nothing more. Do I also have to explain 
what a Pretest is?

What you omitted in your quote is the reference to README.W32. IF we 
need to include any clarifying information we should include it in 
README.W32 and I will only reference the it in any future announcement.

It is an _Emacs_ announcement.  If you also mention other stuff then some brief
description of its relation to Emacs is in order (i.e., helpful).

Agreed.

The readme is the only place we mention other Windows binaries - e.g. image
binaries.  Why treat GnuTLS specially?  Either mention GnuTLS only in the readme
(preferred) or mention in the announcement each of the binaries that mentioned
in the readme (not preferred).

Wherever GnuTLS is mentioned, the mention should be accompanied by a short
description.  IMO, the readme is the proper place for this.

I requested that GnuTLS be treated specially.  I believe this is
necessary because it's important for secure networking on W32, unlike
any of the other libraries.  This is a temporary remedy; I will work on
a W32 installer and then it won't be necessary to mention GnuTLS
explicitly (a link to the installer in the announcement would be sufficient).

1. According to Eli, "It's an email authentication package."  Which would mean
that it is needed only by people who use Emacs for email.

At a minimum, that should be pointed out in the brief description that needs to
accompany this "special treatment".

And that's the case wherever we choose to describe GnuTLS.  (And it should be
described in the README, irregardless of whether it is described in the
announcement.)

(FWIW, I expect that most Windows users do not and will not use Emacs for
email.)


2. I'm not familiar with your proposed "installer", but I certainly hope that we
will continue to distribute a simple zip archive with a Windows binary.

A priori, I for one will not use an installer to "install" the binary.  I use
multiple Emacs Windows binaries, and I do not need an Emacs installer mucking
about with my registry etc.  This is one reason I do not use Lennart's
installer, for instance.

It is blindingly simple for a user to unzip an archive in a directory of choice,
and create a startup shortcut.  Nothing to it.

What's the motivation for this installer?  I can understand Lennart's
motivation, since he has apparently customized many things, including at the C
level.  But why do you think Emacs users on Windows need an installer for
vanilla Emacs?

I have nothing against the general idea of our providing an installer in
_addition_ to our providing zip archives, but I would not want to see the latter
practice dropped.

GnuTLS provides SSL and TLS encryption for any network connection, hence
"secure networking" in my earlier message.  It can encrypt e-mail
protocols like IMAP and SMTP but does not deal with e-mail messages.

Any installer I assemble will not replace the Emacs binaries and will
not be as "official" as Christoph's binaries.  It will not involve
emacs-devel resources, at least.

I've covered the reasons for the installer on this list, going back and
forth over several alternatives.  This was a very recent thread.  An
installer seems to be the best approach but you can read through the
discussion and decide for yourself.

Thanks for that.

There are actually two lists for this thread.  One of them is
help-emacs-windows, which has Windows users, not necessarily Emacs developers,
as participants and readers.

You were not specific about which thread, so I searched the emacs-devel header
lines for "windows",  "installer" (no hits for that one), and "GnuTLS".

I came across this, as the last post for what is presumably the thread in
question (?):

That doesn't seem to quite correspond to what we're seeing now (GnuTLS mentioned
in the announcement, and with no description of it) or with what you are arguing
for (an Emacs installer for Windows), but perhaps you meant something different.

Anyway, I'm glad to hear that Windows binaries will continue to be published.
Thanks.

This is indexed under the GnuTLS mailing list by Gmane because that's
where the thread started, but it should give you enough reading for a
few days :)

What other features in Emacs use TLS as of this writing?  I thought
only email protocols do, which is why I described GnuTLS as I did.

If other protocols we have can be secured by GnuTLS, there seems to be
a gap in our documentation, because I couldn't find any place where
that is mentioned, except in relation to SMTP and the likes.

Any network connection can use it.  I think Lars introduced that option,
and at least HTTP/S connections can use it.

(subject adjusted accordingly)

It's a replacement for the previous libraries that managed secure
connections, except it doesn't depend on external binaries.  So it
really doesn't change much in terms of Emacs functionality, only in the
underlying implementation.  There is one annoying detail with the cert
bundle on W32.  It defaults to /etc/ssl/certs/ca-certificates.crt which
is not valid on W32 and on many other platforms.  See
`open-gnutls-stream' and the rest of gnutls.el.  I was going to bring in
the Mozilla cert bundle with the binary installer I'm planning so I
didn't attack this problem sooner; if you have suggestions for the
default cert bundle on W32 let me know.

Lisp programmers should know they can use TLS when Emacs was compiled
with GnuTLS support.  Users should know that as well, because they
will need to set up their machines for that.  E.g., this:

I think the potential use is just as important, since much of Emacs's
utility is in 3rd party packages.  But Stefan answered about the actual
uses in the Emacs trunk; the URL package is most important (because of
package.el) to the Emacs users in general.

>> I think Lars introduced that option, and at least HTTP/S connections

EZ> Then this needs to be documented somewhere.

I agree.

`open-network-stream' has some documentation, and is most useful as an
API.

User customization of gnutls.el is minimal right now, just
`gnutls-algorithm-priority' and `gnutls-min-prime-bits'.  But those are
tricky: the specific library that uses the API may need to override them
too.  And generally they should not be tweaked.  So I'm not sure those
two deserve more mention in the manual.

I mentioned this because it's the only important GnuTLS-related
configuration bit on all platforms.  It should be in the manual, I
think, but consider that I proposed a while back that Emacs should ship
with its own version of the Mozilla cert bundle, so that this works on
all platforms, but that was not OK with the maintainers.  

So that leaves us with the options of 1) trusting the platform (which
doesn't work on W32, AFAIK it doesn't have a cert bundle we can use; and
many GNU/Linux distros don't have a cert bundle in a standard place or
at all), or 2) making the cert bundle a GNU ELPA package than any
installer or user can activate.

Because of these concerns, currently we don't verify the peer
certificate in SSL and TLS connections.  See `gnutls-negotiate' for how
that would work.  The connections are still encrypted, but you could be
talking to an impostor.

I prefer the GNU ELPA package approach instead of trusting the platform,
but I also think the user should be able to customize this (and an
installer should offer the choice).  Coming back to documentation, I'd
like to settle the greater question of how to distribute the cert bundle
before we document the configuration options for it.

WDYT?

After discussing this with Stefan Monnier, I've decided to proceed as
follows:

New variable `gnutls-trustfiles' will be a list of trustfiles for your
platform, filtered by file existence.  It can take functions in the
list, and the functions can return a list of files or a single file.
When the list is empty, you'll get a message to look in the GNU ELPA for
fallbacks.

A new GNU ELPA package "cert-bundle-mozilla" will provide a fallback
from Mozilla's certificate bundle.  It will be versioned same as that
bundle and updated periodically.  When you install that package, it will
add a function to `gnutls-trustfiles' to load the package's cert bundle
file.

I need a list of possible cert bundle locations on all the platforms
Emacs supports, or methods to retrieve them.  Please send to me directly
or follow up here.  The assembled list will help me greatly.

I'll start with the easiest ones (please correct me if any are wrong,
based on http://mercurial.selenic.com/wiki/CACertificates):

Debian, Ubuntu, Gentoo and Arch Linux: /etc/ssl/certs/ca-certificates.crt (maintained by `update-ca-certificates').

Fedora and RHEL: /etc/pki/tls/certs/ca-bundle.crt

Suse: /etc/ssl/ca-bundle.pem

Mac OS X has the certificate list in the system keychain.  If we had
keychain access functions in Emacs, or a shell call to dump the
contents, I could export it.  Any help is welcome.

W32 doesn't seem to have a system cert bundle and getting it from any
specific browser is unreliable, but any suggestions are welcome.

I think you are wrong about that.  Where did you get this information?

Can you show me an example of a "cert bundle", i.e. what kind of
directory hierarchy, if any, is there, and what files can one find
there?  Examples of how files are named and their contents will help.
I need this to compare with what I think is a cert bundle on my
Windows box (if I'm not mistaken).

TIA

Web searching, e.g. the URL I cited in the post you quoted.  I'd love to

Certificate bundles are usually in a .pem format (I've also seen .crt,
and unfortunately there are at least 4 different formats).  

On W32, I know the MSysGit environment has a cert bundle (inherited from
curl/libcurl and placed under /usr/bin IIRC), but I don't think there's
a generally available bundle.  They consist of hundreds of text blocks
like this:

-----BEGIN CERTIFICATE-----
MIIDpDCCAoygAwIBAgIBATANBgkqhkiG9w0BAQUFADBjMQswCQYDVQQGEwJVUzEc
...
MMbHNYaz+ZZfRtsMRf3zUMNvxsNIrUam4SdHCh0Om7bCd39j8uB9Gr784N/Xx6ds
sPmuujz9dLQR6FgNgLzTqIA6me11zEZ7
-----END CERTIFICATE-----

which are simply individual .pem files, concatenated.  In Debian/Ubuntu
there is a directory structure under /etc/ssl, but Mozilla's bundle, for
instance, is offered as simply a monolithic download.

The question is how to obtain one reliably, and all my research leads me
to believe that W32 doesn't have it.

This URL:

   http://technet.microsoft.com/en-us/library/cc962104.aspx

and also a few others seem to indicate that each Windows user has
his/her certificates in this directory:

  C:\Documents and Settings\<username>\Application Data\Microsoft\SystemCertificates\My\Certificates

I do have such a directory on my XP box, but it is empty.  Meanwhile,
the application that is used on Windows to browse certificates does
show a long list of certificates I allegedly have on this box.

On another XP system I did see files in the above directory, but they
were binary files, unlike the contents you show:

I know nothing about these issues, so I'm really not the right person
to look into this.  Perhaps someone else could chime in.

That's unfortunate.  I'll assume for now that on W32 we have to supply
our own certificate bundle through the GNU ELPA package, until someone
comes up with a better solution.  I think that's acceptable since we're
simply mimicking Mozilla's CA choices, and we can make incremental
improvements to gnutls.el as we find out more about each platform.

Thanks!

It appears that Windows stores the certificates in the registry - see
"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SystemCertificates".

I expect that additonal locations are used under the control of group
policy for domain machines etc, and that this data should only be used
via the appropriate APIs.

Cygwin also has a cert bundle in the ca-certificates package - see 
http://cygwin.com/packages/ca-certificates/

Thanks.  FWIW, there's also

   HKEY_CURRENT_USER\Software\Microsoft\SystemCertificates

for the user's certificates.  But what I see there, in both locations,
are binary blobs, not anything like what Ted showed.

There are many certificate formats GnuTLS can speak; the .pem files I
showed are most common where legibility matters.  Can Emacs extract
everything under this registry path automatically?  I didn't see a way
in the C code.  If I can slurp them into a file, I may be able to use
that.

Thanks

Why do you need it to be on a file?  Emacs on Windows can access the
Registry as easily as it can access files.

The question is, can whatever you are using or writing read and use
the format of the certificates stored in the Windows Registry?

The GnuTLS API can take a file name or binary blobs in DER or PEM
format, according to the docs.  We only support file names right now.  I
would make the necessary changes if it was necessary to load the
registry blobs.

Unfortunately according to
http://citrixblogger.org/2010/09/13/public-key-certificate-locations-in-windows/
the story is much more complicated, with some certificates stored to
disk and so on.  It looks like a much better idea to use certreq.exe or
certutil.exe to dump all the trusted certificates, if those tools
support it.  Does anyone know?

Thanks
Ted

Please do not read these registry keys - you will almost certainly end
up using revoked certificates (e,.g. diginotar), and duplicating the
work of the existing system APIs but with added bugs.

Please read the following articles:

Certificate Status and Revocation Checking - TechNet Articles - Home - TechNet Wiki
<http://social.technet.microsoft.com/wiki/contents/articles/4954.certificate-status-and-revocation-checking.aspx>

How Certificate Revocation Works
<http://technet.microsoft.com/en-gb/library/ee619754(WS.10).aspx>

There is lots of information there about how this works for various
Windows versions.

As I said later, the complexity of this task indicates we should use the
certutil.exe binary or something like it.  I am not excited to spend
hours reverse-engineering Microsoft's certificate storage strategy and
it would be a brittle solution in any case since it changes with W32
releases.

No ChangeLog yet, just the code.  It's pretty simple.

`gnutls-flatten-list' seems like a nice general utility, maybe it
already exists?

The trustfiles parameter is a list of files, all the way through to
gnutls.c.  I don't think it should be demoted to a single file in the
customization interface, and it still needs a function choice.

Also I don't want to decide the default bundle file names at the time
the defcustom is evaluated.  Since `gnutls-trustfiles' can contain
function calls, I'd like it to be called when it's needed.  For
instance, it's very common to store certificates as PEM files in a
directory, and the user should be able to choose that approach instead
of managing a concatenated bundle.  If we built the file list only once,
the modular approach would fail.  Another situation is on W32, where the
cert bundle has to be dynamically built (which will require some caching
but should still be done as close to using the bundle as possible).

OK, but the variable should not be a "list of (function or filename)".
That's ugly.  Maybe we can have it be "a function or a list of files".

I see how it's confusing.

OK.  Patch attached for your review.  The code is simpler now and the
list flattening function is not needed.

If approved I think I should also write a manual entry for this new
variable.  Should I make a new manual subsection for GnuTLS-related
things?  Where?

Now we'll have three customizable variables in gnutls.el
(`gnutls-algorithm-priority', `gnutls-trustfiles', and
`gnutls-min-prime-bits') which is tipping the scales I think.  Plus it
will be good to explain what gnutls.el+gnutls.c do and how to debug
problems with them, since most users and developers don't know how
widely they are used in Emacs 24.

Thanks!

I don't see how to update it appropriately.  I could add "Please see
`gnutls-trustfiles'" somewhere in the docstring but it would be a pretty
random reference.  Maybe Lars has an opinion?

I don't mean "update it with gnutls-trustfiles info", but "update it to
document the new "&rest PARAMS" keyword arguments.  At that point there
will be a place where you can document gnutls-trustfiles.

I'm confused.  The keyword arguments of `open-network-stream' are
already documented.  Do you mean I should add a new :trustfiles argument
and pass that down to `network-stream-open-starttls', and in the
documentation for that argument mention `gnutls-trustfiles'?

Thanks

FWIW, on RHEL6 I have both /etc/pki/tls/certs/ca-bundle.crt:

# This is a bundle of X.509 certificates of public Certificate

and /etc/pki/tls/certs/ca-bundle.trust.crt:

Me neither, and I have no RHEL systems.

According to
http://rpmfind.net/linux/RPM/fedora/15/i386/ca-certificates-2011.70-2.fc15.noarch.html
both of these are in the ca-certificates Fedora package.  So I would
guess the differences are cosmetic and the files are equivalent.  But if
anyone knows different, please let us know.

You are right: this is a false alarm.  Let Symantec people know about
it, and ask them to get their act together.

That's hopeless, especially since we're now up to about 3 maybe 4 such
false alarms (ie, from different Wolf-Crying Peter companies).

(1) They'll say "better safe than sorry," and guess what? they're
    right! (as far as that goes, see (2)).

(2) It's impossible for anybody but Microsoft to truly get the act
    together, because the 3rd party virus checkers have to look for
    "signatures" in the content.  This is so that software whose whole
    selling point is "you don't need to know squat to use this because
    it's all automatic" can continue to oh-so-conveniently
    automatically run pretty much anything you download off the
    InterSewer.  False positives are pretty much inevitable with this
    technology.

And they're only going to only become more common, since viruses are
proliferating at the rate of what, about 1000 new variants a day?

I think you're just going to have to grin and bear this, because the
only alternative that's acceptable to the vast majority of Windows
customers is not safe 'nets, it's what Richard likes to call
"treacherous computing".  Let's pray that that does not become The
Final Solution.

But maybe Ted Z and GnuTLS can save the day.  GnuTLS is universally
applicable security for the network I hear! ;-)

Is all this based on facts or on assumptions?  IOW, did you ever
report such problems to Symantec, and got the above as response?

I don't know about Symantec (don't use their products), but with AVG
it works as expected: you submit the offending file for their
analysis, via the GUI of the antivirus program, and get an email
notification, usually within hours, saying that it's a false alarm;
and the virus database is updated within a couple of days accordingly.

So if Symantec is really behaving like you describe, their users
should simply find a better product.

That's what I would expect from Symantec, too.  But "submit the file
and get it fixed in a few days" is not what I understood from your
post.  "Get your act together" implies "you shouldn't be making
mistakes like this in the first place", not "I understand these things
happen, but you made a mistake here, please fix it."

I think they /should/ get their act together, but I'm not gonna hold my
breath.

Even if someone else has seen it, the right way to deal with it is to
bug the virus-s[cp]a[nm][nm]er.

Only the antivirus programs.

Ok, I have sent a bug report and pointed to this thread (since it was
here I mentioned it).

I got a reply from Avast today. They said they were working on it and
when I just tested the problem seems to be fixed.

For Cygwin 1.7.x that should be as below:


1) /usr/ssl/certs/ca-bundle.crt

# This is a bundle of X.509 certificates of public Certificate
# Authorities.  It was generated from the Mozilla root CA list.


2) /usr/ssl/certs/ca-bundle.trust.crt

# This is a bundle of X.509 certificates of public Certificate
# Authorities.  It was generated from the Mozilla root CA list.
# These certificates are in the OpenSSL "TRUSTED CERTIFICATE"
# format and have trust bits set accordingly.


The comments suggest that this pair of files have similar meaning to the
Redhat certs mentioned upthread.

I am reluctant to add them both blindly, as with RHEL.  What's the
difference in Cygwin and in RHEL?

Whoops, I had typo.

It should be "certs" with an "s":


/usr/ssl/certs/ca-bundle.crt
