2024-05-13daemon: Loop over ‘copy_file_range’ upon short writes....Fixes <https://issues.guix.gnu.org/70877>. * nix/libutil/util.cc (copyFile): Loop over ‘copy_file_range’ instead of throwing upon short write.

2024-03-12daemon: Address shortcoming in previous security fix for CVE-2024-27297....This is a followup to 8f4ffb3fae133bb21d7991e97c2f19a7108b1143. Commit 8f4ffb3fae133bb21d7991e97c2f19a7108b1143 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.

2024-03-11daemon: Protect against FD escape when building fixed-output derivations (CVE......This fixes a security issue (CVE-2024-27297) whereby a fixed-output derivation build process could open a writable file descriptor to its output, send it to some outside process for instance over an abstract AF_UNIX socket, which would then allow said process to modify the file in the store after it has been marked as “valid”. Vulnerability discovered by puck <https://github.com/puckipedia>. Nix security advisory: https://github.com/NixOS/nix/security/advisories/GHSA-2ffj-w4mj-pg37 Nix fix: https://github.com/NixOS/nix/commit/244f3eee0bbc7f11e9b383a15ed7368e2c4becc9 * nix/libutil/util.cc (readDirectory): Add variants that take a DIR* and a file descriptor. Rewrite the ‘Path’ variant accordingly. (copyFile, copyFileRecursively): New functions. * nix/libutil/util.hh (copyFileRecursively): New declaration. * nix/libstore/build.cc (DerivationGoal::buildDone): When ‘fixedOutput’ is true, call ‘copyFileRecursively’ followed by ‘rename’ on each output.

2022-12-18daemon: Make "opening file" error messages distinguishable....* nix/libstore/build.cc (DerivationGoal::openLogFile): Customize "opening file" error message. * nix/libutil/hash.cc (hashFile): Likewise. * nix/libutil/util.cc (readFile, writeFile): Likewise. Ludovic Courtès
