This patch adds restorecon_xattr(8) to find and/or remove
security.restorecon_last entries added by setfiles(8) or
restorecon(8). Uses the services of selinux_restorecon_xattr(3).

- improves the manual page for both setfiles and restorecon (formatting
including alphabetical re-ordering of options, undocumented options,
references and a few cosmetic changes);
- de-hardcodes a couple of constants in the source files and makes a
dynamic use of them to create the manual pages after the compilation
and prior to the installation: more specifically the constants are the
number of errors for the setfiles' validation process abort condition
and the sensitivity of the progress meter for both programs (uses
external programs grep and awk);
- improves the usage message for both programs and introduces a -h
(aliased with currently existing -?) option where not already
available;
- print out the usage message for restorecon when it is called without
arguments;
- white-space/tab conversion to get proper indentation towards the end
of the main source file.

This is purely personal preference. Most of the Makefiles use $() for
Makefile variables, but a couple of places use ${}. Since this obscured
some later Makefile changes I figured I'd just make them all the same up
front.

Subject: policycoreutils: share setfiles restore function with restorecond
Date: Wed, 19 Aug 2009 15:51:44 -0400
This is the first of two patches.
This patch splits all of the restore functionality in setfiles
into another two files, restore.c and restore.h.
The reason for this is shown in the next patch, which patches
restorecond to share this code.
To use it, instantiate a restore_opts struct with the proper options
and then pass a pointer to it into restore_init, and call restore_destroy
later.

I've rebased this so that it will apply to current trunk.

This is version 5 of the setfiles to fts patch.
The code has been cleaned up to adhere to the CodingStyle guidelines.
I have confirmed that the stat struct that fts returns for a symlink when using
the FTS_PHYSICAL flag is in fact the stat struct for the symlink, not the file
it points to (st_size is 8 bytes).
Instead of using fts_path for getfilecon/setfilecon it now uses fts_accpath,
which should be more efficient since fts walks the file hierarchy for us.
FreeBSD setfsmac uses fts in a similar way to how this patch does and one
thing that I took from it was to pass the FTSENT pointer around instead of
the names, because although fts_accpath is more efficient for get/setfilecon,
it is less helpful in verbose output (fts_path will give the entire path).
Here is the output from running restorecon on /
(nftw version)
restorecon -Rv / 2>/dev/null
restorecon reset /dev/pts/ptmx context system_u:object_r:devpts_t:s0->system_u:object_r:ptmx_t:s0
(new version)
./restorecon -Rv / 2>/dev/null
./restorecon reset /dev/pts/ptmx context system_u:object_r:devpts_t:s0->system_u:object_r:ptmx_t:s0
Here are some benchmarks each was run twice from a fresh
boot in single user mode (shown are the second runs).
(nftw version)
restorecon -Rv /usr
real 1m56.392s
user 1m49.559s
sys 0m6.012s
(new version)
./restorecon -Rv /usr
real 1m55.102s
user 1m50.427s
sys 0m4.656s
So not much of a change, though some work has been pushed from kernel space
to user space.
It turns out setting the FTS_XDEV flag tells fts not to descend into
directories with different device numbers, but fts will still give back the
actual directory. I think nftw would completely avoid the directories as well
as their contents.
This patch fixed this issue by saving the device number of the directory
that was passed to setfiles and then skipping all action on any directories
with a different device number when the FTS_XDEV flag is set.
Also removed some code that removed beginning and trailing slashes
from paths, since fts seems to handle it.
