cp: -a now preserves SELinux context, with reduced diagnostics

2009-02-18T14:27:10Z

* copy.c (copy_reg): Reduce SELinux context diagnostics for 'cp -a'. (copy_internal): Likewise * copy.h (cp_options): Add boolean reduce_diagnostics. * cp.c (usage): Say that --archive (-a) behaves like -dR --preserve=all. (cp_option_init): Initialize added reduce_diagnostics. (main): Add reduce_diagnostics for the -a option, and preserve SELinux context, if possible. * mv.c (cp_options_init): Initialize new cp_options booleans. * install.c (cp_option_init): Likewise. * NEWS: Mention those behaviour changes. * doc/coreutils.texi: Document --preserve=context, document that diagnostics are not shown for failures of non-mandatory attributes (just SELinux at the moment). * tests/cp/cp-a-selinux: Check not only failures, but succesful use of preserving SELinux context in cp.

reflect gnulib's removal of lstat.h

2008-10-21T06:10:29Z

* src/copy.h: Don't include "lstat.h". * src/ls.c: Likewise. * src/remove.c: Likewise. * src/rm.c: Likewise.

Make copyright comments consistent.

2008-02-28T18:53:07Z

* src/mktemp.c: Update copyright to use newer form. Make first copyright lines consistent. Some did not end in ", Inc.". Due to that missing ", Inc" at end of line, emacs' copyright-updating code missed some opportunities. This corrects most of those, and adds some mistakenly omitted years. * src/chown-core.c: Adjust. * src/chown-core.h: Likewise. * src/copy.c: Likewise. * src/copy.h: Likewise. * src/cp-hash.c: Likewise. * src/cp.c: Likewise. * src/group-list.h: Likewise. * src/mktemp.c: Likewise. * src/stat.c: Likewise. * tests/chmod/equal-x: Likewise. * tests/dd/skip-seek: Likewise. * tests/envvar-check: Likewise. * tests/mv/into-self-2: Likewise.

Fix a security race with "cp -p A B" when B already exists.

2007-12-01T09:09:57Z

* src/copy.h (struct cp_options): New member owner_privileges. * src/copy.c (USE_ACL): Define to 0 if not defined, for convenience. (owner_failure_ok): New function. (set_owner): Avoid a security-related race by doing an extra chmod first if it looks like there might be trouble right after a chown. Accept a source struct stat rather than a uid and gid, and accept a boolean NEW_DST and destination struct stat. All callers changed. * src/copy.h (cp_options_default): New function, replacing the old chown_privileges. * src/copy.c (cp_options_default): Likewise. * src/cp.c (cp_option_init): Use it. * src/install.c (cp_option_init): Likewise. * src/mv.c (cp_option_init): Likewise.

cp: by default, refuse to copy through a dangling destination symlink

2007-11-21T23:19:06Z

* NEWS: Mention this change. * doc/coreutils.texi (cp invocation): Describe the new behavior. * src/copy.c: No longer include "canonicalize.h". (copy_reg): Upon failure to open a dangling destination symlink, don't canonicalize the name, but rather fail (default) or, with POSIXLY_CORRECT, repeat the open call without O_EXCL (potentially dangerous). * src/copy.h (struct cp_options) [open_dangling_dest_symlink]: New member. Reorder the others, grouping "bool" and "enum" members together. * tests/cp/thru-dangling: Test for changed and new behavior. * src/cp.c (cp_option_init): Initialize new member. * src/install.c (cp_option_init): Likewise. * src/mv.c (cp_option_init): Likewise.

Update all copyright notices to use the newer form.

2007-07-23T12:35:58Z

Change "version 2" to "version 3" in all copyright notices.

Correct cp's handling of destination symlinks in some cases.

2007-06-15T20:47:16Z

* NEWS: "cp" no longer considers a destination symlink to be the same as the referenced file when copying links or making backups. * src/copy.c (copy_reg): When following a symlink, use the followed name in later chown etc. requests, so that the created file is affected, rather than the symlink. Use O_NOFOLLOW on source when not dereferencing symlinks; this avoids a race. Preserve errno correctly when doing multiple open attempts on the destination. (copy_internal): Follow destination symlinks only when copying a regular file and only when we don't intend to remove or rename the destination first, regardless of whether following source symlinks; this is because since POSIX and tradition (e.g., FreeBSD) say we should ordinarily follow destination symlinks if the system calls would ordinarily do so. * src/copy.h (struct cp_options): Add comment that 'dereference' is only for source files. * src/cp.c (usage): Note that --derereference etc. are only for source files. (make_dir_parents_private): Follow symlinks, regardless of whether --dereference is specified, because these are destination symlinks. * tests/cp/same-file: Adjust tests to match revised behavior. Filter out perror output since it might vary from host to host. Use sed alone instead of also using echo. * doc/coreutils.texi (cp invocation): Document the behavior better when the destination is a symlink. Clarify source versus destination symlinks. Describe the new behavior for destination symlinks. 2007-06-15 Jim Meyering * src/copy.c: Include "canonicalize.h". (copy_reg): Use canonicalize_filename_mode to follow the symlink, so that we can always open with O_EXCL and avoid a race.
