Xtables-addons 1.31

This patch adds a module which is useful to users of grsecurity's RBAC
system. It matches packets based on whether RBAC is enabled or
disabled.

See: http://grsecurity.net/

Jan Engelhardt> Also, I do not see a xt_gradm.c in this patch.

This [xt_gradm.c] is part of the grsecurity patch which not only adds
the Xtables code, but also the RBAC code. Without the entire RBAC
stuff, xt_gradm does not make sense and so it is included with the
grsecurity patch to the kernel, and not this patch to Xtables-addons.

The idea here is that when the RBAC rulesets are not being enforced,
the system is more vulnerable and the user wants stricter firewall
rules. When RBAC is being enforced, one can relax the firewall and
access to services which are now better protected. In practice this
usually means allowing only access to some trusted IP(s) on boot
before RBAC is turned on.

 ====
 
 
+v1.31 (November 05 2010)
+========================
+- LOGMARK: print remaining lifetime of cts
+- build: improve detection of kernel version and error handling
+- build: automatically derive Xtables module directory, thus
+  --with-xtlibdir is no longer needed for ./configure in most cases
+  (If I still see a distro using it, I will scold you for not
+  reading this changelog.)
+- xt_iface: allow matching against incoming/outgoing interface
+- libxt_gradm: match packets based on status of grsecurity RBAC
+  (userspace part only - xt_gradm is in the grsec patch)
+
+
+v1.30 (October 02 2010)
+=======================
+- update to ipset 4.4
+  * ipport{,ip,net}hash did not work with mixed "src" and "dst"
+    destination parameters
+- deactivate building xt_TEE and xt_CHECKSUM by default, as these have been
+  merged upstream in Linux 2.6.35 and 2.6.36, respectively.
+  Distros still wishing to build this need to enable it in their build
+  script, e.g. perl -i -pe 's{^build_TEE=.*}{build_TEE=m}' mconfig;
+
+
+v1.29 (September 29 2010)
+=========================
+- compat_xtables: return bool for match_check and target_check in 2.6.23..34
+- ipset: enable building of ip_set_ipport{ip,net}hash.ko
+- support for Linux 2.6.36
+- SYSRQ: resolve compile error with Linux 2.6.36
+- TEE: resolve compile error with Linux 2.6.36
+- add workaround for broken linux-glibc-devel 2.6.34 userspace headers
+  ("implicit declaration of function 'ALIGN'")
+
+
 Xtables-addons 1.28 (July 24 2010)
