2006-03-21[NETFILTER]: Fix CID offset bug in PPTP NAT helper debug messageHolger Eitzenberger
The recent (kernel 2.6.15.1) fix for PPTP NAT helper introduced a bug - which only appears if DEBUGP is enabled though. The calculation of the CID offset into a PPTP request struct is not correct, so that at least not the correct CID is displayed if DEBUGP is enabled. This patch corrects CID offset calculation and introduces a #define for that.

2006-03-21[DCCP] CCID2: Drop sock reference count on timer expiration and reset.Andrea Bittau
There was a hybrid use of standard timers and sk_timers. This caused the reference count of the sock to be incorrect when resetting the RTO timer. The sock reference count should now be correct, enabling its destruction, and allowing the DCCP module to be unloaded.

2006-03-21[NETFILTER] nf_conntrack: clean up to reduce size of 'struct nf_conn'Harald Welte
This patch moves all helper related data fields of 'struct nf_conn' into a separate structure 'struct nf_conn_help'. This new structure is only present in conntrack entries for which we actually have a helper loaded. Also, this patch cleans up the nf_conntrack 'features' mechanism to resemble what the original idea was: Just glue the feature-specific data structures at the end of 'struct nf_conn', and explicitly re-calculate the pointer to it when needed rather than keeping pointers around. Saves 20 bytes per conntrack on my x86_64 box. A non-helped conntrack is 276 bytes. We still need to save another 20 bytes in order to fit into to target of 256bytes.

2006-03-21[VLAN]: translate IF_OPER_DORMANT to netif_dormant_on()Stefan Rompf
this patch adds support to the VLAN driver to translate IF_OPER_DORMANT of the underlying device to netif_dormant_on(). Beside clean state forwarding, this allows running independant userspace supplicants on both the real device and the stacked VLAN. It depends on my RFC2863 patch.

2006-03-21[NET] core: add RFC2863 operstateStefan Rompf
this patch adds a dormant flag to network devices, RFC2863 operstate derived from these flags and possibility for userspace interaction. It allows drivers to signal that a device is unusable for user traffic without disabling queueing (and therefore the possibility for protocol establishment traffic to flow) and a userspace supplicant (WPA, 802.1X) to mark a device unusable without changes to the driver. It is the result of our long discussion. However I must admit that it represents what Jamal and I agreed on with compromises towards Krzysztof, but Thomas and Krzysztof still disagree with some parts. Anyway I think it should be applied.
