2008-07-02mac80211: get rid of function pointers in RX pathJohannes Berg
This changes the RX path to no longer use function pointers for RX handlers but rather invoke them directly. If debugging is enabled, mark the RX handlers noinline because otherwise they all get inlined into ieee80211_invoke_rx_handlers() which makes it harder to see where a bug is.

2008-06-30mac80211: add beacon timestamp to beacon template in IBSSAssaf Krauss
This patch adds a beacon timestamp to the beacon template used in IBSS mode. This way the underlying driver can update its TSF accordingly. According the spec station should adopt the highest TSF from an incoming beacons in the cell.

2008-06-30build algorithms into the mac80211 moduleAdrian Bunk
The old infrastructure was: - the default algorithm is built into mac80211 - other algorithms get into their own modules The implementation of this complicated scheme was horrible (just look at net/mac80211/Makefile), and anyone adding a new algorithm would most likely not get it right at his first attempt. This patch therefore builds all enabled algorithms into the mac80211 module. The user interface for the rate control algorithms changes as follows: - first the user can choose which algorithms to enable (currently only MAC80211_RC_PID is available) - if more than one algorithm is enabled (currently not possible since only one algorithm is present) the user then chooses the default one Note: - MAC80211_RC_PID is always enables for CONFIG_EMBEDDED=n Technical changes: - all selected algorithms get into the mac80211 module - net/mac80211/Makefile can now become much less complicated - support for rc80211_pid_algo.c being modular is no longer required - this includes unexporting mesh_plink_broken Signed-off-by: Adrian Bunk <bunk@kernel.org> Signed-off-by: John W.

2008-06-18Revert "mac80211: Use skb_header_cloned() on TX path."David S. Miller
This reverts commit 608961a5eca8d3c6bd07172febc27b5559408c5d. The problem is that the mac80211 stack not only needs to be able to muck with the link-level headers, it also might need to mangle all of the packet data if doing sw wireless encryption. This fixes kernel bugzilla #10903. Thanks to Didier Raboud (for the bugzilla report), Andrew Prince (for bisecting), Johannes Berg (for bringing this bisection analysis to my attention), and Ilpo (for trying to analyze this purely from the TCP side). In 2.6.27 we can take another stab at this, by using something like skb_cow_data() when the TX path of mac80211 ends up with a non-NULL tx->key. The ESP protocol code in the IPSEC stack can be used as a model for implementation. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-06-16wext: Emit event stream entries correctly when compat.David S. Miller
Three major portions to this change: 1) Add IW_EV_COMPAT_LCP_LEN, IW_EV_COMPAT_POINT_OFF, and IW_EV_COMPAT_POINT_LEN helper defines. 2) Delete iw_stream_check_add_*(), they are unused. 3) Add iw_request_info argument to iwe_stream_add_*(), and use it to size the event and pointer lengths correctly depending upon whether IW_REQUEST_FLAG_COMPAT is set or not. 4) The mechanical transformations to the drivers and wireless stack bits to get the iw_request_info passed down into the routines modified in #3. Also, explicit references to IW_EV_LCP_LEN are replaced with iwe_stream_lcp_len(info). With a lot of help and bug fixes from Masakazu Mokuno. Signed-off-by: David S. Miller <davem@davemloft.net>

2008-06-14mac80211: eliminate IBSS warning in rate_lowest_index()Vladimir Koutny
In IBSS mode prior to join/creation of new IBSS it is possible that a frame from unknown station is received and an ibss_add_sta() is called. This will cause a warning in rate_lowest_index() since the list of supported rates of our station is not initialized yet. The fix is to add ibss stations with a rate we received that frame at; this single-element set will be extended later based on beacon data. Also there is no need to store stations from a foreign IBSS. Signed-off-by: Vladimir Koutny <vlado@ksp.sk> Signed-off-by: John W. Linville <linville@tuxdriver.com>
