[Bug 2130465] Re: cp commands fails when process is in deleted directory

Sat Sep 12 20:25:50 UTC 2026

This bug was fixed in the package rust-coreutils - 0.10.0-1ubuntu3

---------------
rust-coreutils (0.10.0-1ubuntu3) stonking; urgency=medium

  [ Simon Johnsson ]
  * d/p/cp-fix-umask-permission-denied.patch: Fix an issue where cp would fail
    with "Permission denied" if umask masked the owner's write permission
    (LP: #2164777).

  [ Varun Varma ]
  * d/p/cp-stop-resolving-cwd.patch: cp: avoid resolving cwd
    for absolute recursive copies (LP: #2130465).
  * Fix Lintian warnings.

rust-coreutils (0.10.0-1ubuntu2) stonking; urgency=medium

  * d/p/cp-fix-symlink-target-permissions.patch: Fix an issue where cp
    would alter the permissions of the source file, such as stripping the
    setuid bit (LP: #2165041)

rust-coreutils (0.10.0-1ubuntu1) stonking; urgency=medium

  [ Simon Johnsson ]
  * Merge with Debian unstable. Remaining changes: (LP: #2163175)
    - Install libstdbuf.so: Modify d/rules to export LIBSTDBUF_DIR as to not
      skip stdbuf, fix libstdbuf.so permissions, and install it in
      rust-coreutils.install.
    - Install hardlinks: Rename rust-coreutils.links to
      rust-coreutils.hardlinks.
    - Enable feat_systemd_logind: This allows commands such as who and pinky
      to work correctly. Introduces libsystemd-dev as a dependency.
    - Remove Build-Depends on lld: Debian added it as the preferred linker,
      but some partial architectures like i386 may be missing it.
    - d/rules: Fix vendored sources field creation. Debian does not have
      access to dh-cargo-vendored-sources so it uses a script instead.
      Change it to use dh-cargo-vendored-sources on Ubuntu instead.
    - d/rules: Skip failing tests.
    - Add patches:
      + build-stty
      + dd-ensure-full-writes
      + require-utility-to-be-invoked-at-matching-path
      + Tweak-release-build-profile
      + rust-vendor/glibc-2.42
      + rustix-use-libc-backend
    - Remove upstream patches:
      + fix-ppc64el-baudrate.diff: Launchpad's builders instead fails on
        ppc64le for this patch, the original source code is correct.
    - Update vendored rust crates
    - debian/control: Update XS-Vendored-Sources-Rust field
  * Drop changes:
    - Remove patches fixed upstream:
      + cp-respect-composite-flag
      + fix-cp-parents
      + fix-incomplete-locale-bundles
      + fix-locale-path: Debian adopted this patch.
  * New changes:
    - debian/patches/remove-workspace-members.patch: Remove workspace member
      array to prevent dh-cargo bypassing workspace-exclude.patch. Otherwise
      vendored dependencies would still think that they're part of the
      workspace.
  * Fixes:
    - File ownership changes when a file is mv'ed by root to a different file
      system (LP: #2134860)
    - Failing to build images: mv resolv.conf.tmp
      /build/chroot/etc/resolv.conf mv: File exists (os error 17)
      (LP: #2159679)
    - unaligned plus in "ls -l" output (LP: #2132368)
    - git-buildpackage ftbfs on resolute-proposed due to rust coreutils
      (LP: #2137580)
    - env: signal flags do not understand RTMIN+n notation (LP: #2142900)
    - date: width prefix in %N format specifier is ignored
      ( %3N, %6N always output full 9 nanosecond digits) (LP: #2150342)
    - changes in behaviour of cp in coreutils-from-uutils break test case in
      util-linux (LP: #2157011)
    - systemd: TEST-45-TIMEDATE is flaky with rust coreutils (LP: #2157342)

  [ Varun Varma ]
  * debian/patches/df-statfs-fallback.patch: Add a fallback to statfs if the
    mount path could not be found normally (LP: #2116290).

Title:
  cp commands fails when process is in deleted directory

Status in rust-coreutils:
  Fix Released
Status in rust-coreutils package in Ubuntu:
  Fix Released

Bug description:
  If the current directory of a process is deleted and the process runs
  the Rust cp command it will faile with:

  /usr/lib/cargo/bin/coreutils/cp: failed to get current directory No
  such file or directory (os error 2)

  The GNU version of cp does not have this issue.

  As a result, some automated build processes (which arrive at this
  situation) now fail to run.

  You can see the error by using this simple shell script:

  ====================
  #!/bin/sh
  #

  echo Rust core-utils

  cd $HOME
  mkdir -p cu-test-base
  touch cu-test-base/file1 cu-test-base/file2
  mkdir -p cu-test
  cd cu-test
  rm -rf $HOME/cu-test
  /usr/lib/cargo/bin/coreutils/cp  -r $HOME/cu-test-base  $HOME/cu-test
  ls $HOME/cu-test

  #####################

  echo GNU core-utils

  cd $HOME
  mkdir -p cu-test-base
  touch cu-test-base/file1 cu-test-base/file2
  mkdir -p cu-test
  cd cu-test
  rm -rf $HOME/cu-test
  /usr/bin/gnucp  -r $HOME/cu-test-base  $HOME/cu-test
  ls $HOME/cu-test
