Brian McKenna 3baf8be1d1 Fix broken call to shellwords

Philip Potter 4f3cf06c97 Verify TLS certificate before downloading binaries
The --insecure flag to curl tells curl not to bother checking if the TLS
certificate presented by the server actually matches the hostname
requested, and actually is issued by a trusted CA chain.  This almost
entirely negates any benefit from using TLS in the first place.

This removes the --insecure flag to ensure we actually have a secure
connection to the intended hostname before downloading binaries.

Manually tested locally within a dev-shell; was able to download
binaries from https://cache.nixos.org without issue.

[Note: --insecure was only used for fetching NARs, whose integrity is
verified by Nix anyway using the hash from the .narinfo. But if we can
fetch the .narinfo without --insecure, we can also fetch the .nar, so
there is not much point to using --insecure. --Eelco]

Eelco Dolstra c0d4173263 Set default binary-caches-parallel-connections to 25
Some benchmarking suggested this as a good value. Running

  $ benchmark -f ... -t 25 -- sh -c 'rm -f /nix/var/nix/binary-cache*; nix-store -r /nix/store/x5z8a2yvz8h6ccmhwrwrp9igg03575jg-nixos-15.09.git.5fd87e1M.drv --dry-run --option binary-caches-parallel-connections <N>'

gave the following mean elapsed times for these values of N:

N=10:  3.3541
N=20:  2.9320
N=25:  2.6690
N=30:  2.9417
N=50:  3.2021
N=100: 3.5718
N=150: 4.2079

Memory usage is also reduced (N=150 used 186 MB, N=25 only 68 MB).

Closes #708.

Utku Demir a49514a2e2 Also set CURLOPT_SSL_VERIFYHOST=0 when "verify-https-binary-caches" is false
This makes that option even more insecure, by also not checking the SSL host.

But without this parameter, one can still get SSL errors even when
"verify-https-binary-caches" is false, which is unexpected IMO.

Eelco Dolstra e012c126db Revert "add the manpath to the installer"
This reverts commit 76f985b92d. We
shouldn't mess with $MANPATH, because on some "man" implementations
(like NixOS'), the default value on $MANPATH is derived from $PATH. So
if you set $MANPATH, you lose the default locations.

Eelco Dolstra f19b4abfb2 Include NAR size in fingerprint computation
This is not strictly needed for integrity (since we already include
the NAR hash in the fingerprint) but it helps against endless data
attacks [1]. (However, this will also require
download-from-binary-cache.pl to bail out if it receives more than the
specified number of bytes.)

Jeff Ramnani d53735c823 Nix install script failed when "cd" printed to stdout.
In some cases the bash builtin command "cd" can print the variable $CWD
to stdout.  This caused the install script to fail while copying files
because the source path was wrong.

Fixes #476.

2015-02-08 20:44:05 -05:00
Eelco Dolstra f3a5930488 Sign a subset of the .narinfo
We only need to sign the store path, NAR hash and references (the
"fingerprint"). Everything else is irrelevant to security. For
instance, the compression algorithm or the hash of the compressed NAR
don't matter as long as the contents of the uncompressed NAR are
correct.

(Maybe we should include derivers in the fingerprint, but they're
broken and nobody cares about them. Also, it might be nice in the
future if .narinfos contained signatures from multiple independent
signers. But that's impossible if the deriver is included in the
fingerprint, since everybody will tend to have a different deriver for
the same store path.)

Also renamed the "Signature" field to "Sig" since the format changed
in an incompatible way.

Eelco Dolstra e0def5bc4b Use libsodium instead of OpenSSL for binary cache signing
Sodium's Ed25519 signatures are much shorter than OpenSSL's RSA
signatures. Public keys are also much shorter, so they're now
specified directly in the nix.conf option ‘binary-cache-public-keys’.

The new command ‘nix-store --generate-binary-cache-key’ generates and
prints a public and secret key.

Eelco Dolstra 128538ef06 nix-shell: Add --run flag
‘--run’ is like ‘--command’, except that it runs the command in a
non-interactive shell. This is important if you do things like:

  $ nix-shell --command make

Hitting Ctrl-C while make is running drops you into the interactive
Nix shell, which is probably not what you want. So you can now do

  $ nix-shell --run make

instead.

Eelco Dolstra b76589206a nix-shell: Interpret filenames relative to the #!-script
So you can have a script like:

  #! /usr/bin/env nix-shell
  #! nix-shell script.nix -i python

  import prettytable

  x = prettytable.PrettyTable(["Foo", "Bar"])
  for i in range(1, 10): x.add_row([i, i**2])
  print x

with a ‘script.nix’ in the same directory:

  with import <nixpkgs> {};

  runCommand "dummy" { buildInputs = [ python pythonPackages.prettytable ]; } ""

(Of course, in this particular case, using the ‘-p’ flag is more
convenient.)

Eelco Dolstra a957893b26 Allow nix-shell to be used as a #! interpreter
This allows scripts to fetch their own dependencies via nix-shell. For
instance, here is a Haskell script that, when executed, pulls in GHC
and the HTTP package:

  #! /usr/bin/env nix-shell
  #! nix-shell -i runghc -p haskellPackages.ghc haskellPackages.HTTP

  import Network.HTTP

  main = do
    resp <- Network.HTTP.simpleHTTP (getRequest "http://nixos.org/")
    body <- getResponseBody resp
    print (take 100 body)

Or a Perl script that pulls in Perl and some CPAN packages:

  #! /usr/bin/env nix-shell
  #! nix-shell -i perl -p perl perlPackages.HTMLTokeParserSimple perlPackages.LWP

  use HTML::TokeParser::Simple;

  my $p = HTML::TokeParser::Simple->new(url => 'http://nixos.org/');

  while (my $token = $p->get_tag("a")) {
      my $href = $token->get_attr("href");
      print "$href\n" if $href;
  }

Note that the options to nix-shell must be given on a separate line
that starts with the magic string ‘#! nix-shell’. This is because
‘env’ does not allow passing arguments to an interpreter directly.

Eelco Dolstra a5c6347ff0 build-remote.pl: Use ‘nix-store --serve’ on the remote side
This makes things more efficient (we don't need to use an SSH master
connection, and we only start a single remote process) and gets rid of
locking issues (the remote nix-store process will keep inputs and
outputs locked as long as they're needed).

It also makes it more or less secure to connect directly to the root
account on the build machine, using a forced command
(e.g. ‘command="nix-store --serve --write"’). This bypasses the Nix
daemon and is therefore more efficient.

Also, don't call nix-store to import the output paths.
