* udp: add a missing smp_wmb() in udp_lib_get_port()Eric Dumazet2008-11-011-0/+5
| | | | | | | | | | | | | | | | Corey Minyard spotted a missing memory barrier in udp_lib_get_port() We need to make sure a reader cannot read the new 'sk->sk_next' value and previous value of 'sk->sk_hash'. Or else, an item could be deleted from a chain, and inserted into another chain. If new chain was empty before the move, 'next' pointer is NULL, and lockless reader can not detect it missed following items in original chain. This patch is temporary, since we expect an upcoming patch to introduce another way of handling the problem. Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.

* xfrm6: handling fragmentNicolas Dichtel2008-11-011-3/+6
| | | | | | | | | | | | | | | | | | | | | | RFC4301 Section 7.1 says: "7.1. Tunnel Mode SAs that Carry Initial and Non-Initial Fragments All implementations MUST support tunnel mode SAs that are configured to pass traffic without regard to port field (or ICMP type/code or Mobility Header type) values. If the SA will carry traffic for specified protocols, the selector set for the SA MUST specify the port fields (or ICMP type/code or Mobility Header type) as ANY. An SA defined in this fashion will carry all traffic including initial and non-initial fragments for the indicated Local/Remote addresses and specified Next Layer protocol(s)." But for IPv6, fragment is treated as a protocol. This change catches protocol transported in fragmented packet. In IPv4, there is no problem.

* orinoco: cache downloadable firmware image in memory for use during resumeAndrey Borzenkov2008-10-312-7/+26
| | | | | | | | | | | If card is using downloadable firmware (like Agere 9.x), firmware has to be reloaded during resume. It is not possible to use request_firmware for that, because tasks are still frozen, so request_firmware will just timeout and fail.

* wireless: clean up regulatory ignore_request functionJohannes Berg2008-10-311-40/+27
| | | | | | | | | | | | | | | | | | | | | This function has a few WARNs that may eventually trigger when an AP sends rogue beacons, those must be removed. Some of the comments in the function are also inappropriate as this function is concerned with the global hint, not a per- wiphy thing (which a multidomain flag on a wiphy would imply). I'm convinced that we don't need to do anything to implement multi-domain capability as 802.11-2007 specifies it because it makes only two things mandatory: * starting of BSS/IBSS must have country information (this can easily be done with a mac80211 patch) * a STA must adopt the country information (we already have the framework for this) But we don't have anything implemented anyway for now.

* iwl3945: iwl3945_mac_get_tsf() should not return zeroFabrice Bellet2008-10-311-9/+0
| | | | | | | | | | | | | | | | The problem fixed here is that iwl3945_mac_get_tsf() returns 0, as the function is not implemented, and this is considered as a valid value by the mac layer in mlme.c:1605. The consequence is that the STA in ad-hoc mode is inserted/removed quite frequently due to IBSS merging.

| | | | | | | | | | | | | | | | | I noticed that when for some reason [1] the probe or auth times out, wpa_supplicant doesn't realise this and only tries the next AP when it runs into its own timeout, which is ten seconds, and that's quite long. Fix this by making mac80211 notify userspace that it didn't associate. [1] my wrt350n in mixed B/G/HT mode often runs into this, maybe it's because one of the antennas is broken off and for whatever reason it decides to use that antenna to transmit the response frames (auth, probe); I do see beacons fine so it's not totally broken.
