Ludovic Courtès ff1251de0b daemon: Address shortcoming in previous security fix for CVE-2024-27297. ... This is a followup to 8f4ffb3fae. Commit 8f4ffb3fae fell short in two ways: (1) it didn’t have any effet for fixed-output derivations performed in a chroot, which is the case for all of them except those using “builtin:download” and “builtin:git-download”, and (2) it did not preserve ownership when copying, leading to “suspicious ownership or permission […] rejecting this build output” errors. * nix/libstore/build.cc (DerivationGoal::buildDone): Account for ‘chrootRootDir’ when copying ‘drv.outputs’. * nix/libutil/util.cc (copyFileRecursively): Add ‘fchown’ and ‘fchownat’ calls to preserve file ownership; this is necessary for chrooted fixed-output derivation builds. * nix/libutil/util.hh: Update comment.
