File coreutils-copy-fix-selinux-existing-dirs.patch of Package coreutils-testsuite.669
Upstream patch on top of 8.22: http://lists.gnu.org/archive/html/coreutils/2014-01/msg00012.html Stripped down to the relevant part: NEWS and THANKS.in chunks removed. Original NEWS entry: cp -a again sets the correct SELinux context for existing directories in the destination. Previously it set the context of an existing directory to that of its last copied descendent. [bug introduced in coreutils-8.22] Originally reported for Fedora by Michal Trunecka in rh#1045122: https://bugzilla.redhat.com/show_bug.cgi?id=1045122 ______________________________________________________________________ From f2f8b688b87b94ed3551f47f9a6422c873acf5d1 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?P=C3=A1draig=20Brady?= <P@draigBrady.com> Date: Sun, 5 Jan 2014 15:00:55 +0000 Subject: [PATCH] copy: fix SELinux context preservation for existing directories * src/copy.c (copy_internal): Use the global process context to set the context of existing directories before they're populated. This is more consistent with the new directory case, and fixes a bug for existing directories where we erroneously set the context to the last copied descendent, rather than to that of the source directory itself. * tests/cp/cp-a-selinux.sh: Add a test for this case. --- src/copy.c | 13 ++++++++++++- tests/cp/cp-a-selinux.sh | 15 +++++++++++++++ 2 files changed, 27 insertions(+), 1 deletion(-) Index: src/copy.c =================================================================== --- src/copy.c.orig +++ src/copy.c @@ -2408,6 +2408,17 @@ copy_internal (char const *src_name, cha else { omitted_permissions = 0; + + /* For directories, the process global context could be reset for + descendents, so use it to set the context for existing dirs here. + This will also give earlier indication of failure to set ctx. */ + if (x->set_security_context || x->preserve_security_context) + if (! set_file_security_ctx (dst_name, x->preserve_security_context, + false, x)) + { + if (x->require_preserve_context) + goto un_backup; + } } /* Decide whether to copy the contents of the directory. */ @@ -2598,7 +2609,7 @@ copy_internal (char const *src_name, cha /* With -Z or --preserve=context, set the context for existing files.
