2010-04-12doc: clarify when cp and mv output xattr warningsPádraig Brady
The 2010-03-26 commit, 4c38625e, "doc: fix info on cp --preserve..." was not entirely correct as cp --preserve=all does produce some xattr warnings. * src/copy.h: Update and clarify the comments for reduce_diagnostics and require_preserve_{xattr,context}. * doc/coreutils.texi (cp invocation): Update the -a and --preserve=xattr,context options to say when and which xattr warnings are output. (mv invocation): Mention that some warnings are output when preserving xattrs.

* 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.

2008-10-21reflect gnulib's removal of lstat.hJim Meyering
* src/copy.h: Don't include "lstat.h". * src/ls.c: Likewise. * src/remove.c: Likewise. * src/rm.c: Likewise.
2008-02-28Make copyright comments consistent.Jim Meyering
* 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.
2007-12-01Fix a security race with "cp -p A B" when B already exists.Paul Eggert
* 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.
2007-11-22cp: by default, refuse to copy through a dangling destination symlinkJim Meyering
* 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.

2007-07-10Change "version 2" to "version 3" in all copyright notices.Jim Meyering
2007-06-15Correct cp's handling of destination symlinks in some cases.Paul Eggert
* 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 <jim@meyering.net> * 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.
2007-03-29* tests/cp/cp-a-selinux: New file. Test for the bug reported inJim Meyering
* tests/cp/Makefile.am (TESTS): Add cp-a-selinux. * tests/selinux: New file. * tests/Makefile.am (EXTRA_DIST): Add selinux. * tests/misc/selinux: Source the new script, rather than open coding it. Change how "cp -a" and "cp --preserve=context" work with SELinux. Now, cp -a attempts to preserve context, but failure to do so does not change cp's exit status. However "cp --preserve=context" is similar, but failure *does* cause cp to exit with nonzero status. * src/copy.h (struct cp_options) [require_preserve_context]: New member. * src/copy.c (copy_reg, copy_internal): Implement the above. * src/mv.c (cp_option_init): Initialize the new member. * src/install.c (cp_option_init): Likewise. * src/cp.c (cp_option_init): Likewise. (decode_preserve_arg): Set it or reset it. FIXME: add an on-writable-NFS-only test
2007-03-29cp, mv, install: add SELinux support, but unlike with the Red HatJim Meyering
patch, mv and cp do not provide the "-Z context" option. * src/copy.c: Include <selinux/selinux.h>. (restore_default_fscreatecon): New function. (copy_reg): Make cp --preserve=context work for existing destination. (copy_internal): Likewise for new destinations. * src/copy.h (cp_options) [preserve_security_context]: New member. * src/cp.c: Include <selinux/selinux.h>. (selinux_enabled): New global. (usage): Mention new --preserve=context option. (PRESERVE_CONTEXT): Define/use. (decode_preserve_arg): Handle PRESERVE_CONTEXT. (main): Remove an obsolete comment. If --preserve=context is specified on a system without SELinux enabled, give a diagnostic and fail. * src/mv.c: Include <selinux/selinux.h>. Set x->preserve_security_context if SELinux is enabled. * src/install.c: Accept new "-Z, --context=C" option. Accept --preserve-context option (but not -P option). Accept alternate spelling: --preserve_context, for now. Include <selinux/selinux.h> and "quotearg.h". (selinux_enabled, use_default_selinux_context): New globals. (PRESERVE_CONTEXT_OPTION): Define. (cp_option_init): Default: do not preserve security context. (setdefaultfilecon): New function. (main): Honor new options. * src/Makefile.am (mv_LDADD, cp_LDADD, ginstall_LDADD): Add $(LIB_SELINUX).
2006-12-06* NEWS: Document the cp --preserve=ownership fix.Paul Eggert
* m4/jm-macros.m4 (coreutils_MACROS): Check for fchmod. * src/copy.c (fchmod_or_lchmod): New function. (copy_reg): New arg OMITTED_PERMISSIONS. All uses changed. Omit confusing and unused ", dst_mode" arg to 'open' without O_CREAT. When creating a file, use O_EXCL, so we're more likely to detect funny business by other processes. At the end, if permissions were omitted, chmod them back in. (copy_internal): If the ownership might change, omit some permissions at first, then restore them after chowning the file. * src/cp.c (make_dir_parents_private): Likewise. * src/copy.c (cached_umask): New function. * src/copy.h (cached_umask): New decl.
