* src/ls.c (gobble_file): Much like the 2007-04-07 fix,
add a term to the expression that decides whether we need
stat and/or lstat calls. Reported by Andreas Frische.
* src/split.c (line_bytes_split): Don't create an empty line
afterwards if the last buffer happens to be exactly full.
* tests/misc/split-fail: Add a test case for this.
* NEWS: mention this.
* src/ls.c (gobble_file): Form and compute length of strings for
block size, owner, group, author, major+minor numbers and file size
only if they'll actually be used. I.e., don't form most of them
when not producing long format output.
ls -x DIR would sometimes output the wrong string in place of the
first entry.
* NEWS: Mention the bug fix.
* tests/ls/x-option: New file.
* tests/ls/Makefile.am (TESTS): Add x-option.
Ulrich Drepper in <http://bugzilla.redhat.com/232652>.
* tests/misc/runcon-no-reorder: New file. Test for the above.
* tests/misc/Makefile.am (TESTS): Add runcon-no-reorder.
* tests/Makefile.am (t9): New target, to run tests/cp/cp-a-selinux.
(all_t): Add t9.
Use a directory on a loopback device mounted with -o context=...
* tests/cp/cp-a-selinux: Since this test now runs mount and umount,
it is a root-only one.
* 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
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).
* src/id.c (main): Apply patches from Fedora, with these changes:
Remove #ifdef WITH_SELINUX.
Use error (EXIT_FAILURE, not fprintf+exit(1).
* src/Makefile.am (id_LDADD): Define, so as to add $(LIB_SELINUX).
I started with the patches from Red Hat.
The entries below tell how the code evolved.
* src/ls.c (print_long_format, print_file_name_and_frills): When
there is no security context (due to getfilecon/lgetfilecon failing
with e.g. ENOTSUP), print it as "?", not "".
* src/ls.c (print_file_name_and_frills): Make -Z work without -l.
(length_of_file_name_and_frills): Likewise.
* src/ls.c: Remove the --lcontext and --scontext options.
Change the way -Z, --context work so that it no longer implies -l.
Thus, -Z -l will work like -lcontext and -Z without -l will work
like --scontext.
Adjust tests to reflect new 'ls -l' syntax -- affects only
systems with SELinux when operating on a file with no ACL.
These tests assumed that everything before the first space on
each line is the 10-byte mode string. But there may also be a "+"
in the 11th column, just before the space. However, note that this
is not new. The same thing would have happened even without the
change below, when listing a file with an ACL.
* tests/chmod/equals, tests/cp/cp-parents, tests/cp/fail-perm:
* tests/cp/link-preserve, tests/install/basic-1, tests/misc/mknod:
* tests/mkdir/parents, tests/mkdir/special-1, tests/mv/partition-perm:
Don't make compilation depend on USE_ACL. An SELinux security
context counts as an "alternate access control method", so ls
must output a "+" for each file with a security context.
* src/ls.c [struct fileinfo] (have_acl): Declare unconditionally.
(FILE_HAS_ACL): Remove macro definition. Use f->have_acl directly.
(gobble_file): Record whether a file has a security context, and
update the condition used to determine whether to print the "+".
(gobble_file): Call getfilecon/lgetfilecon also when
format == long_format, so that we get the "+".
* src/ls.c (gobble_file): Add a comment explaining why (with a
security context option) ls doesn't exit nonzero due to e.g.,
getfilecon failing with errno == ENOTSUP.
* src/ls.c (gobble_file): Ignore failure of getfilecon if it's due
to ENOTSUP.
* src/ls.c (gobble_file): Factor out three small blocks using
getfilecon and lgetfilecon.
Don't ignore return value from getfilecon and lgetfilecon.
* src/ls.c (print_long_format): Don't use ?: (empty 2nd arg with C
ternary operator).
(print_scontext_format): Likewise.
(print_scontext): Declare to be "bool", not int. Adjust uses.
* src/Makefile.am (dir_LDADD, ls_LDADD, vdir_LDADD): Add $(LIB_SELINUX).
* tests/misc/chcon: New file.
* tests/misc/chcon-fail: New file.
* tests/Makefile.am (check-root): Run new, root-only misc/chcon test.
* tests/misc/Makefile.am (TESTS): Add chcon and chcon-fail.
* tests/misc/Makefile.am (TESTS): Add selinux.
* tests/misc/selinux: New file.
* tests/help-version: Skip chcon.
