A small series of iptables userspace cleanups

A small series of iptables userspace cleanups

[Maciej Żenczykowski]

I'm going to follow up on this email with a small series of 17 patches
to userspace iptables code.
These patches have all received extensive testing when applied to 1.4.4.
I've ported the patches and tested that everything compiles cleanly
with current head, but they don't have nearly the same level of
thorough testing.

* The first patch simply allows targets and matches to include
underscores.  Without this the relevant man page sections don't get
included.

* The second is a trivial application of a Redhat/Fedora FD_CLOEXEC patch.

* The third fixes an ipv6 comment thinko/typo.

* The fourth is more complex: it delays match and target
initialization to later on.
For built-in matches/targets we run their init code regardless of what
we're doing.
Unfortunately init code can result in modules being autoloaded as a
result of version probing.
This is undesirable, by splitting registration into two fragments this
is prevented.
The code is just a teeny bit tricky because of some pointer to pointer
link muckery.

* The remaining 13 patches rename functions which are duplicated
between v4 and v6 code to suffix '4' or '6'.
After these renames are applied the following grep correctly results
in nothing being found:
  egrep --exclude-dir=.git -r
'(^|[^_])(init_extensions|for_each_chain|flush_entries|delete_chain|print_rule|do_command)([^46]|$)'
.

This combined with the previous patch will hopefully allow building a
single multi-purpose busybox-style ipv4 and ipv6 capable ip6?tables
binary.
I have this working for iptables 1.4.4, but haven't yet ported all of
the Makefile/etc changes to the current iptables master branch.

With UPX compression a relatively full-featured static multipurpose
single-binary build of 1.4.4 uses 100KB for i386 and 120KB for x86_64.

/sbin/iptables -> /bin/argv0switch
/sbin/iptables32 -> xtables-tiny32
/sbin/iptables64 -> xtables-tiny64
/sbin/iptables-restore -> /bin/argv0switch
/sbin/iptables-restore32 -> xtables-tiny32
/sbin/iptables-restore64 -> xtables-tiny64
/sbin/iptables-save -> /bin/argv0switch
/sbin/iptables-save32 -> xtables-tiny32
/sbin/iptables-save64 -> xtables-tiny64
/sbin/xtables-tiny32 [100796 bytes]
/sbin/xtables-tiny64 [120044 bytes]

(as you can probably guess /bin/argv0switch picks argv0+"32" or
argv[0]+"64" based on machine architecture)

Cheers,
Maciej Żenczykowski

[PATCH 03/17] xtables_ip6addr_to_numeric: fix typo in comment

[Maciej Żenczykowski]

From: Maciej Żenczykowski <maze@google.com>

An IPv6 address consists of eight hexadecimal 16-bit values seperated
by colons, or alternatively, six (not five) of these followed by a colon
and an IPv4 address in standard dotted decimal quad notation
(for IPv4 mapped addresses and the like).

[PATCH 04/17] Delay (statically built) match/target initialization

[Maciej Żenczykowski]

From: Maciej Żenczykowski <maze@google.com>

Matches and targets built into the iptables static binary will always
be registered as the binary starts up, this may potentially (as a result
of kernel version support checking) result in modules being autoloaded.

This is undesirable (for example it may cause CONNMARK target to load
and thus cause the kernel to load the conntrack module, which isn't a no-op).

Transition to a system where matches and targets are registered into
a pending list, from whence they get fully registered only when required.

Re: [PATCH 02/17] mark newly opened fds as FD_CLOEXEC (close on exec)

[Maciej Żenczykowski]

> Redhat still has not given a reason as to why this is needed.

I believe:
  a) the fact CLOEXEC isn't the default on new fd's is a (UNIX/POSIX)
API bug (which of course can't be fixed...)
  b) not setting CLOEXEC on every fd is an application bug (with the
exception of the specific few fd's you actually want inherited)
  c) iptables does occasionally fork/exec (to load modules), for
example "/sbin/modprobe ip6_tables -q", but also for match/target
revision compatibility checking, and when it does this it can call
modprobe with additional opened descriptors (for example sockfd inside
of compatible_revision isn't closed before fork/exec modprobe) - this
is unclean, and could potentially cause security warnings (or even
issues?) since iptables and modprobe have different contexts.

[fc14]# ls -alZ `which iptables`
lrwxrwxrwx. root root system_u:object_r:bin_t:s0       /sbin/iptables
-> iptables-multi
[fc14]# ls -alZ /sbin/iptables-multi
-rwxr-xr-x. root root system_u:object_r:iptables_exec_t:s0 /sbin/iptables-multi
[fc14]#  ls -alZ `which modprobe`
-rwxr-xr-x. root root system_u:object_r:insmod_exec_t:s0 /sbin/modprobe

I'm not going to claim I fully understand the security implications of
leaving the file descriptor open across exec, but there is clearly no
reason to do so, hence the patch.

Re: [PATCH 05/17] v4: rename init_extensions() to init_extensions4()

[Maciej Żenczykowski]

To be able to combine iptables-multi and ip6tables-multi into one
binary (ie. to avoid duplicate symbol definition problems at link
time).

Also applied, thanks.

If you plan to submit more patches in the future, I'd appreciate it
if you would combine simple patches that basically all do the same
things like the v4 and v6 renames into a single larger patch.

Ok, I was assuming review would be easier with simpler patches.
Does your request also hold true if I provide a git repo to pull from?

That's always preferred, but I think it would still make sense to
fold a bunch of renames that happen for the same purpose into a
single patch. If it gets to large, one patch for v4 and one for v6
would also be fine.
