336c4270c6 Make the default impure prefix (not actual allowed impurities!) include all of /System/Library, since we also want PrivateFrameworks from there and (briefly) TextEncodings, and who knows what else. Yay infectious impurities? 2015-03-02 23:01:24 -05:00

99897f6979 Use chroots for all derivations
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.

5451b8db9d Use pivot_root in addition to chroot when possible
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.

79ca503332 Allow using /bin and /usr/bin as impure prefixes on non-darwin by default
These directories are generally world-readable anyway, and give us the two
most common linux impurities (env and sh)

100961e370 Don't resolve symlinks while checking __impureHostDeps
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.

27b7b94923 Set /nix/store permission to 1737
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).

b7b6e3ddec Build derivations in a more predictable order
Derivations are now built in order of derivation name, so a package
named "aardvark" is built before "baboon".

8299aaf079 Disable vacuuming the DB after garbage collection
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.
