* ipvs: SCTP Trasport Loadbalancing SupportVenkata Mohan Reddy2010-02-18
| | | | | | | | | | | Enhance IPVS to load balance SCTP transport protocol packets. This is done based on the SCTP rfc 4960. All possible control chunks have been taken care. The state machine used in this code looks some what lengthy. I tried to make the state machine easy to understand.

| * netfilter: ebt_limit: add CONFIG_COMPAT supportFlorian Westphal2010-02-16
| | | | | | | | | | | | | | | | | | | | ebt_limit structure is larger on 64 bit systems due to "long" type used in the (kernel-only) data section. Setting .compatsize is enough in this case, these values have no meaning in userspace. Signed-off-by: Florian Westphal <fwestphal@astaro.com>
| * netfilter: ebtables: try native set/getsockopt handlers, tooFlorian Westphal2010-02-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ebtables can be compiled to perform userspace-side padding of structures. In that case, all the structures are already in the 'native' format expected by the kernel. This tries to determine what format the userspace program is using. For most set/getsockopts, this can be done by checking the len argument for sizeof(compat_ebt_replace) and re-trying the native handler on error. In case of EBT_SO_GET_ENTRIES, the native handler is tried first, it will error out early when checking the *len argument (the compat version has to defer this check until after iterating over the kernel data set once, to adjust for all the structure size differences). As this would cause error printks, remove those as well, as recommended by Bart de Schuymer. Signed-off-by: Florian Westphal <fw@strlen.de>
| * netfilter: ebtables: add CONFIG_COMPAT supportFlorian Westphal2010-02-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Main code for 32 bit userland ebtables binary with 64 bit kernels support. Tested on x86_64 kernel only, using 64bit ebtables binary for output comparision. At least ebt_mark, m_mark and ebt_limit need CONFIG_COMPAT hooks, too. remaining problem: The ebtables userland makefile has: ifeq ($(shell uname -m),sparc64) CFLAGS+=-DEBT_MIN_ALIGN=8 -DKERNEL_64_USERSPACE_32 endif struct ebt_replace, ebt_entry_match etc. then contain userland-side padding, i.e. even if we are called from a 32 bit userland, the structures may already be in the right format. This problem is addressed in a follow-up patch. Signed-off-by: Florian Westphal <fwestphal@astaro.com>

* | net: bug fix for vlan + gro issueAjit Khaparde2010-02-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Traffic (tcp) doesnot start on a vlan interface when gro is enabled. Even the tcp handshake was not taking place. This is because, the eth_type_trans call before the netif_receive_skb in napi_gro_finish() resets the skb->dev to napi->dev from the previously set vlan netdev interface. This causes the ip_route_input to drop the incoming packet considering it as a packet coming from a martian source. I could repro this on 2.6.32.7 (stable) and 2.6.33-rc7. With this fix, the traffic starts and the test runs fine on both vlan and non-vlan interfaces.

These annotations are to make sparse consider percpu variables to be in a different address space and warn if accessed without going through percpu accessors. This patch doesn't affect normal builds. The macro and type tricks around snmp stats make things a bit interesting. DEFINE/DECLARE_SNMP_STAT() macros mark the target field as __percpu and SNMP_UPD_PO_STATS() macro is updated accordingly.

| * | | | netfilter: CONFIG_COMPAT: allow delta to exceed 32767Florian Westphal2010-02-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | with 32 bit userland and 64 bit kernels, it is unlikely but possible that insertion of new rules fails even tough there are only about 2000 iptables rules. This happens because the compat delta is using a short int. Easily reproducible via "iptables -m limit" ; after about 2050 rules inserting new ones fails with -ELOOP. Note that compat_delta included 2 bytes of padding on x86_64, so structure size remains the same. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Patrick McHardy <kaber@trash.net>
| * | | | netfilter: ebtables: avoid explicit XT_ALIGN() in match/targetsFlorian Westphal2010-02-15

Should have zero effect for existing systems: xtables uses XT_ALIGN() whenever it deals with match/target sizes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | next_offset must be > 0, otherwise this loops forever. The offset also contains the size of the ebt_entry structure itself, so anything smaller is invalid.

Conntrack zones allow to specify a numerical zone using the CT target, connections in different zones can use the same identity.
