2015-03-04Don't use vfork() before clone()Eelco Dolstra
I'm seeing hangs in Glibc's setxid_mark_thread() again. This is probably because the use of an intermediate process to make clone() safe from a multi-threaded program (see 524f89f1399724e596f61faba2c6861b1bb7b9c5) is defeated by the use of vfork(), since the intermediate process will have a copy of Glibc's threading data structures due to the vfork(). So use a regular fork() again.

Make the default impure prefix include all of /System/Library
2015-03-02Make the default impure prefix (not actual allowed impurities!) include all ↵Dan Peebles
of /System/Library, since we also want PrivateFrameworks from there and (briefly) TextEncodings, and who knows what else. Yay infectious impurities?

2015-02-23More graceful fallback for chroots on Linux < 2.13Eelco Dolstra
2015-02-23Use chroots for all derivationsEelco Dolstra
If ‘build-use-chroot’ is set to ‘true’, fixed-output derivations are now also chrooted. However, unlike normal derivations, they don't get a private network namespace, so they can still access the network. Also, the use of the ‘__noChroot’ derivation attribute is no longer allowed. Setting ‘build-use-chroot’ to ‘relaxed’ gives the old behaviour.
2015-02-17Use $<attr>Path instead of $<attr> for passAsFileEelco Dolstra
2015-02-17Allow passing attributes via files instead of environment variablesEelco Dolstra
Closes #473.
2015-02-16Use pivot_root in addition to chroot when possibleHarald van Dijk
chroot only changes the process root directory, not the mount namespace root directory, and it is well-known that any process with chroot capability can break out of a chroot "jail". By using pivot_root as well, and unmounting the original mount namespace root directory, breaking out becomes impossible. Non-root processes typically have no ability to use chroot() anyway, but they can gain that capability through the use of clone() or unshare(). For security reasons, these syscalls are limited in functionality when used inside a normal chroot environment. Using pivot_root() this way does allow those syscalls to be put to their full use.

Fixes #453
2015-01-18Make inputs writeable in the sandbox (builds still can’t actually write ↵Daniel Peebles
due to user permissions)
2015-01-13Allow using /bin and /usr/bin as impure prefixes on non-darwin by defaultShea Levy
These directories are generally world-readable anyway, and give us the two most common linux impurities (env and sh)
2015-01-13SysError -> ErrorEelco Dolstra
2015-01-13Don't resolve symlinks while checking __impureHostDepsEelco Dolstra
Since these come from untrusted users, we shouldn't do any I/O on them before we've checked that they're in an allowed prefix.

2015-01-08Set /nix/store permission to 1737Eelco Dolstra
I.e., not readable to the nixbld group. This improves purity a bit for non-chroot builds, because it prevents a builder from enumerating store paths (i.e. it can only access paths it knows about).

This broke building with "-vv", because the builder is not allowed to write to stderr at this point.

2014-11-24Build derivations in a more predictable orderEelco Dolstra
Derivations are now built in order of derivation name, so a package named "aardvark" is built before "baboon". Fixes #399.

2014-11-19Disable vacuuming the DB after garbage collectionEelco Dolstra
Especially in WAL mode on a highly loaded machine, this is not a good idea because it results in a WAL file of approximately the same size ad the database, which apparently cannot be deleted while anybody is accessing it.
