Also, add rules to allow fixed-output derivations to access the
network.
These rules are sufficient to build stdenvDarwin without any
__sandboxProfile magic.
The filename used was not unique and owned by the build user, so
builds could fail with
error: while setting up the build environment: cannot unlink ‘/nix/store/99i210ihnsjacajaw8r33fmgjvzpg6nr-bison-3.0.4.drv.sb’: Permission denied
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.
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.
Fixes
src/libstore/build.cc:2321:45: error: non-constant-expression cannot be narrowed from type 'int' to 'scmp_datum_t' (aka 'unsigned long') in initializer list [-Wc++11-narrowing]
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.
* exwm-workspace--add-frame-as-workspace
(exwm-workspace--add-frame-as-workspace): Manually compare X display
names as there's no built-in function handles this correctly.
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).

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.
