This patch makes enum from the defines previously dwelled inside ieee80211_tx_control for better readability. The patch also addes HT flags, for 802.11n drivers: - IEEE80211_TXCTL_OFDM_HT: request low-level driver to use HT OFDM rates - IEEE80211_TXCTL_GREEN_FIELD: use green field protection - IEEE80211_TXCTL_DUP_DATA: duplicate data on both 20 Mhz channels - IEEE80211_TXCTL_40_MHZ_WIDTH: send this frame in 40Mhz width - IEEE80211_TXCTL_SHORT_GI: send this frame with short guard interval Tx command can be a combination of any of these flags, along with bitrate represented by ieee80211_rate. this will allow legacy drivers to switch easily to any 11n rate representation.

2008-03-06[UDP]: Revert udplite and code split.David S. Miller
This reverts commit db1ed684f6c430c4cdad67d058688b8a1b5e607c ("[IPV6] UDP: Rename IPv6 UDP files."), commit 8be8af8fa4405652e6c0797db5465a4be8afb998 ("[IPV4] UDP: Move IPv4-specific bits to other file.") and commit e898d4db2749c6052072e9bc4448e396cbdeb06a ("[UDP]: Allow users to configure UDP-Lite."). First, udplite is of such small cost, and it is a core protocol just like TCP and normal UDP are. We spent enormous amounts of effort to make udplite share as much code with core UDP as possible. All of that work is less valuable if we're just going to slap a config option on udplite support. It is also causing build failures, as reported on linux-next, showing that the changeset was not tested very well. In fact, this is the second build failure resulting from the udplite change. Finally, the config options provided was a bool, instead of a modular option. Meaning the udplite code does not even get build tested by allmodconfig builds, and furthermore the user is not presented with a reasonable modular build option which is particularly needed by distribution vendors.

Quite a while ago I started this book. The required kernel-doc patches have since gone into the tree so it is now possible to build the book in mainline.

2008-03-04[TCP]: Improve ipv4 established hash function.David S. Miller
If all of the entropy is in the local and foreign addresses, but xor'ing together would cancel out that entropy, the current hash performs poorly. Suggested by Cosmin Ratiu: Basically, the situation is as follows: There is a client machine and a server machine. Both create 15000 virtual interfaces, open up a socket for each pair of interfaces and do SIP traffic. By profiling I noticed that there is a lot of time spent walking the established hash chains with this particular setup. The addresses were distributed like this: client interfaces were 198.18.0.1/16 with increments of 1 and server interfaces were 198.18.128.1/16 with increments of 1. As I said, there were 15000 interfaces. Source and destination ports were 5060 for each connection. So in this case, ports don't matter for hashing purposes, and the bits from the address pairs used cancel each other, meaning there are no differences in the whole lot of pairs, so they all end up in the same hash chain.

2008-03-03[NETNS][IPV6] ip6_fib - add net to gc timer parameterDaniel Lezcano
The fib tables are now relative to the network namespace. When the garbage collector timer expires, we must have a network namespace parameter in order to retrieve the tables. For now this is the init_net, but we should be able to have a timer per namespace and use the timer callback parameter to pass the network namespace from the expired timer. The timer callback, fib6_run_gc, is actually used to be called synchronously by some functions and asynchronously when the timer expires. When the timer expires, the delay specified for fib6_run_gc parameter is always zero. So, I changed fib6_run_gc to not be a timer callback but a function called by the timer callback and I added a timer callback where its work is just to retrieve from the data arg of the timer the network namespace and call fib6_run_gc with zero expiring time and the network namespace parameters. That makes the code cleaner for the fib6_run_gc callers. Signed-off-by: Daniel Lezcano <dlezcano@fr.ibm.com> Signed-off-by: Benjamin Thery <benjamin.thery@bull.net> Signed-off-by: David S.

2008-02-29mac80211: enable IBSS mergingBruno Randolf
enable IBSS cell merging. if an IBSS beacon with the same channel, same ESSID and a TSF higher than the local TSF (mactime) is received, we have to join its BSSID. while this might not be immediately apparent from reading the 802.11 standard it is compliant and necessary to make IBSS mode functional in many cases. most drivers have a similar behaviour. * move the relevant code section (previously only containing debug code) down to the end of the function, so we can reuse the bss structure. * we have to compare the mactime (TSF at the time of packet receive) rather than the current TSF. since mactime is defined as the time the first data symbol arrived we add the time until byte 24 where the timestamp resides, since this is how the beacon timestamp is defined. as some some drivers are not able to give a reliable mactime we fall back to use the current TSF, which will be enough to catch most (but not all) cases where an IBSS merge is necessary. * in IBSS mode we want to allow beacons to override probe response info so we can correctly do merges. * we don't only configure beacons based on scan results, so change that message. * to enable this we have to let all beacons thru in IBSS mode, even if they have a different BSSID.

2008-02-29cfg80211 API for channels/bitrates, mac80211 and driver conversionJohannes Berg
This patch creates new cfg80211 wiphy API for channel and bitrate registration and converts mac80211 and drivers to the new API. The old mac80211 API is completely ripped out. All drivers (except ath5k) are updated to the new API, in many cases I expect that optimisations can be done. Along with the regulatory code I've also ripped out the IEEE80211_HW_DEFAULT_REG_DOMAIN_CONFIGURED flag, I believe it to be unnecessary if the hardware simply gives us whatever channels it wants to support and we then enable/disable them as required, which is pretty much required for travelling. Additionally, the patch adds proper "basic" rate handling for STA mode interface, AP mode interface will have to have new API added to allow userspace to set the basic rate set, currently it'll be empty... However, the basic rate handling will need to be moved to the BSS conf stuff. I do expect there to be bugs in this, especially wrt. transmit power handling where I'm basically clueless about how it should work.
