Always use the Darwin sandbox
Even with "build-use-sandbox = false", we now use sandboxing with a
permissive profile that allows everything except the creation of
setuid/setgid binaries.

Add .editorconfig
- Automatically adjust editor to nix coding style
-> less nitpiks/styling issues in pull requests
-> profit(!)

Remove listxattr assertion
It appears that sometimes, listxattr() returns a different value for
the query case (i.e. when the buffer size is 0).

OS X sandbox: Improve builtin sandbox profile
Also, add rules to allow fixed-output derivations to access the
network.

These rules are sufficient to build stdenvDarwin without any
__sandboxProfile magic.

Eelco Dolstra 44f3f8048f OS X sandbox: Don't use a deterministic $TMPDIR
This doesn't work because the OS X sandbox cannot bind-mount

Eelco Dolstra c740c3ce50 OS X sandbox: Store .sb file in $TMPDIR rather than the Nix store
The filename used was not unique and owned by the build user, so
builds could fail with

resolve-system-dependencies: Fix another segfault
runResolver() was barfing on directories like
/System/Library/Frameworks/Security.framework/Versions/Current/PlugIns. It
should probably do something sophisticated for frameworks, but let's
ignore them for now.

Darwin sandbox: Use sandbox-defaults.sb
Issue #759.

Also, remove nix.conf from the sandbox since I don't really see a
legitimate reason for builders to access the Nix configuration.

Darwin sandbox: Disallow creating setuid/setgid binaries

Eelco Dolstra 83eec5a997 resolve-system-dependencies: Several fixes
This fixes

  error: getting attributes of path ‘Versions/Current/CoreFoundation’: No such file or directory

when /System/Library/Frameworks/CoreFoundation.framework/CoreFoundation is a symlink.

Also fixes a segfault when encounting a file that is not a MACH binary (such
as /dev/null, which is included in __impureHostDeps in Nixpkgs).

Possibly fixes #786.

canonicalisePathMetaData(): Remove extended attributes / ACLs
EAs/ACLs are not part of the NAR canonicalisation. Worse, setting an
ACL allows a builder to create writable files in the Nix store. So get
rid of them.

Closes #185.

Eelco Dolstra 6cc6c15a2d
Add a seccomp filter to prevent creating setuid/setgid binaries
This prevents builders from setting the S_ISUID or S_ISGID bits,
preventing users from using a nixbld* user to create a setuid/setgid
binary to interfere with subsequent builds under the same nixbld* uid.

This is based on aszlig's seccomp code
(47f587700d).

Reported by Linus Heckemann.

Fix nix-copy-closure test
Fixes

  client# error: size mismatch importing path ‘/nix/store/ywf5fihjlxwijm6ygh6s0a353b5yvq4d-libidn2-0.16’; expected 0, got 120264

This is mostly an artifact of the NixOS VM test environment, where the
Nix database doesn't contain hashes/sizes.

Add --with-sandbox-shell configure flag
And add a 116 KiB ash shell from busybox to the release build. This
helps to make sandbox builds work out of the box on non-NixOS systems

Linux sandbox: Don't barf on invalid paths
This is useful when we're using a diverted store (e.g. "--store
local?root=/tmp/nix") in conjunction with a statically-linked sh from
the host store (e.g. "sandbox-paths =/bin/sh=/nix/store/.../bin/busybox").
