* src/ls.c (gobble_file): Upon failed getfilecon, treat an errno value
of EOPNOTSUPP just like ENOTSUP. See <http://bugs.debian.org/488549>.
|
|
* src/ls.c: [HAVE_CAP] Include <sys/capability.h>.
(has_capability): New function for capability detection.
(print_color_indicator): Colorize file with capability.
* m4/jm-macro.m4: New configure option: --disable-libcap.
Check for libcap usability.

When printing one name per line and not sorting, ls now uses
constant memory per directory, no matter how many files are in
the directory.
* ls.c (print_dir): Print each file name immediately, when possible.
* NEWS: Mention the improvement.
|

In 1463824d8e7f72c31f1d803d7cfe2b608ccafc5c, I added some
missing "const" directives, as well as some new, redundant ones.
This removes the redundant ones. Pointed out by Eric Blake.

Upon failed getfilecon, accept not just ENOTSUP, but also ENODATA.
|
|
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.
