* [NETFILTER]: nf_conntrack_sip: create RTCP expectationsPatrick McHardy2008-03-25
| | | | | | | Create expectations for the RTCP connections in addition to RTP connections. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
* [NETFILTER]: nf_conntrack_sip: allow media expectations with wildcard source ↵Patrick McHardy2008-03-25
| | | | | | | | | | | | | | | | address Media streams can come from anywhere, add a module parameter which controls whether wildcard expectations or expectations between the two signalling endpoints are created. Since the same media description sent on multiple connections may results in multiple identical expections when using a wildcard source, we need to check whether a similar expectation already exists for a different connection before attempting to register it.

* [NETFILTER]: nf_conntrack_sip: create signalling expectationsPatrick McHardy2008-03-25
| | | | | | | | | | Create expectations for incoming signalling connections when seeing a REGISTER request. This is needed when the registrar uses a different source port number for signalling messages and for receiving incoming calls from other endpoints than the registrar.

| | | | | | | | | | | | helpers Introduce URI and header parameter parsing helpers.

* [NETFILTER]: nf_conntrack_sip: kill request URI "header" definitionsPatrick McHardy2008-03-25
| | | | | | | | | The request URI is not a header and needs to be treated differently than real SIP headers. Add a seperate function for parsing it and get rid of the POS_REQ_URI/POS_REG_REQ_URI definitions. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

* [NETFILTER]: nf_conntrack_sip: add seperate SDP header parsing functionPatrick McHardy2008-03-25
| | | | | | | | | | | | | | SDP and SIP headers are quite different, SIP can have continuation lines, leading and trailing whitespace after the colon and is mostly case-insensitive while SDP headers always begin on a new line and are followed by an equal sign and the value, without any whitespace. Introduce new SDP header parsing function and convert all users that used the SIP header parsing function. This will allow to properly deal with the special SIP cases in the SIP header parsing function later. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

* [NETFILTER]: nf_conntrack: introduce expectation classes and policiesPatrick McHardy2008-03-25
| | | | | | | | | | | | | | | Introduce expectation classes and policies. An expectation class is used to distinguish different types of expectations by the same helper (for example audio/video/t.120). The expectation policy is used to hold the maximum number of expectations and the initial timeout for each class. The individual classes are isolated from each other, which means that for example an audio expectation will only evict other audio expectations.

* [NETFILTER]: nf_conntrack_expect: support inactive expectationsPatrick McHardy2008-03-25
| | | | | | | | | | | | This is useful for the SIP helper and signalling expectations. We don't want to create a full-blown expectation with a wildcard as source based on a single UDP packet, but need to know the final port anyways. With inactive expectations we can register the expectation and reserve the tuple, but wait for confirmation from the registrar before activating it.

| * mac80211: filter scan results on unusable channelsJohannes Berg2008-03-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When you have an AP on channel 13, it will currently often enough be listed in scan results even when the regulatory domain restricts to channels 1-11. This is due to channel overlap. To avoid getting very strange failures, don't show such APs in the scan results. The failure mode will now go from "I can see the AP but not associate" to "I can't see the AP although I know it's there" which is easier to debug.

This is needed for drivers that don't do the rekeying by themselves (i.e. iwlwifi). Upon IV16 wrap around, the packet is decrypted in SW, if decryption is ok, mac80211 calls to update_tkip_key with a new phase 1 RX key.
