| * | | net: No more expensive sock_hold()/sock_put() on each txEric Dumazet2009-06-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One of the problem with sock memory accounting is it uses a pair of sock_hold()/sock_put() for each transmitted packet. This slows down bidirectional flows because the receive path also needs to take a refcount on socket and might use a different cpu than transmit path or transmit completion path. So these two atomic operations also trigger cache line bounces. We can see this in tx or tx/rx workloads (media gateways for example), where sock_wfree() can be in top five functions in profiles. We use this sock_hold()/sock_put() so that sock freeing is delayed until all tx packets are completed. As we also update sk_wmem_alloc, we could offset sk_wmem_alloc by one unit at init time, until sk_free() is called. Once sk_free() is called, we atomic_dec_and_test(sk_wmem_alloc) to decrement initial offset and atomicaly check if any packets are in flight. skb_set_owner_w() doesnt call sock_hold() anymore sock_wfree() doesnt call sock_put() anymore, but check if sk_wmem_alloc reached 0 to perform the final freeing. Drawback is that a skb->truesize error could lead to unfreeable sockets, or even worse, prematurely calling __sk_free() on a live socket. Nice speedups on SMP. tbench for example, going from 2691 MB/s to 2711 MB/s on my 8 cpu dev machine, even if tbench was not really hitting sk_refcnt contention point. 5 % speedup on a UDP transmit workload (depends on number of flows), lowering TX completion cpu usage.

| * | | mac80211: do not pass PS frames out of mac80211 againJohannes Berg2009-06-10

This, however, also has unnecessary overhead by needing to 'clean up' already tried frames, and this clean-up code is also buggy when software encryption is used. Instead of sending the frames via the master netdev queue again, simply put them into the pending queue. This also fixes a problem where frames for that particular station could be reordered when some were still on the software queues and older ones are re-injected into the software queue after them.

| * | | net: add IEEE 802.15.4 socket family implementationSergey Lapin2009-06-09

This implementation is neither certified nor complete, but aims to that goal. This commit contains only the socket interface for communication over IEEE 802.15.4 networks. One can either send RAW datagrams or use SOCK_DGRAM to encapsulate data inside normal IEEE 802.15.4 packets. Configuration interface, drivers and software MAC 802.15.4 implementation will follow. Initial implementation was done by Maxim Gorbachyov, Maxim Osipov and Pavel Smolensky as a research project at Siemens AG. Later the stack was heavily reworked to better suit the linux networking model, and is now maitained as an open project partially sponsored by Siemens.

| * | | pkt_sched: Change PSCHED_SHIFT from 10 to 6Jarek Poplawski2009-06-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change PSCHED_SHIFT from 10 to 6 to increase schedulers time resolution. This will increase 16x a number of (internal) ticks per nanosecond, and is needed to improve accuracy of schedulers based on rate tables, like HTB, TBF or CBQ, with rates above 100Mbit. It is assumed this change is safe for 32bit accounting of time diffs up to 2 minutes, which should be enough for common use (extremely low rate values may overflow, so get inaccurate instead). To make full use of this change an updated iproute2 will be needed. (But using older iproute2 should be safe too.) This change breaks ticks - microseconds similarity, so some minor code fixes might be needed. It is also planned to change naming adequately eg. to PSCHED_TICKS2NS() etc. in the near future.

This patch provides a new socket option IP_MULTICAST_ALL. In this case, default behaviour is _unchanged_ from the current Linux standard. The socket option is set by default to provide original behaviour. Sockets wishing to receive data only from multicast groups they join explicitly will need to clear this socket option.

* | | netfilter: conntrack: replace notify chain by function pointerPablo Neira Ayuso2009-06-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the notify chain infrastructure and replace it by a simple function pointer. This issue has been mentioned in the mailing list several times: the use of the notify chain adds too much overhead for something that is only used by ctnetlink. This patch also changes nfnetlink_send(). It seems that gfp_any() returns GFP_KERNEL for user-context request, like those via ctnetlink, inside the RCU read-side section which is not valid. Using GFP_KERNEL is also evil since netlink may schedule(), this leads to "scheduling while atomic" bug reports. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

After this patch, the existing events are: * IPCT_NEW, IPCT_RELATED and IPCT_DESTROY, that are used to identify addition and deletion of entries. * IPCT_STATUS, that notes that the status bits have changes, eg. IPS_SEEN_REPLY and IPS_ASSURED. * IPCT_PROTOINFO, that reports that internal protocol information has changed, eg. the TCP, DCCP and SCTP protocol state. * IPCT_HELPER, that a helper has been assigned or unassigned to this entry. * IPCT_MARK and IPCT_SECMARK, that reports that the mark has changed, this covers the case when a mark is set to zero. * IPCT_NATSEQADJ, to report that there's updates in the NAT sequence adjustment.

To actually make use of it we need to redesign things a bit. This patch does the work for that. We do this to so we can obey to regulatory rules accordingly for use of HT40. We end up dealing with HT40 by having two passes for each channel. The first check will see if a 20 MHz channel fits into the channel's center freq on a given frequency range. We check for a 20 MHz banwidth channel as that is the maximum an individual channel will use, at least for now. The first pass will go ahead and check if the regulatory rule for that given center of frequency allows 40 MHz bandwidths and we use this to determine whether or not the channel supports HT40 or not. So to support HT40 you'll need at a regulatory rule that allows you to use 40 MHz channels but you're channel must also be enabled and support 20 MHz by itself. The second pass is done after we do the regulatory checks over an device's supported channel list. On each channel we'll check if the control channel and the extension both: o exist o are enabled o regulatory allows 40 MHz bandwidth on its frequency range This work allows allows us to idependently check for HT40- and HT40+.

| * | net/9p: handle correctly interrupted 9P requestsLatchesar Ionkov2009-04-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the 9p code crashes when a operation is interrupted, i.e. for example when the user presses ^C while reading from a file. This patch fixes the code that is responsible for interruption and flushing of 9P operations. Signed-off-by: Latchesar Ionkov <lucho@ionkov.net>

| * | | nl80211: Add IEEE 802.1X PAE control for station modeJouni Malinen2009-05-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new NL80211_ATTR_CONTROL_PORT flag for NL80211_CMD_ASSOCIATE to allow user space to indicate that it will control the IEEE 802.1X port in station mode. Previously, mac80211 was always marking the port authorized in station mode. This was enough when drop_unencrypted flag was set. However, drop_unencrypted can currently be controlled only with WEXT and the current nl80211 design does not allow fully secure configuration. Fix this by providing a mechanism for user space to control the IEEE 802.1X port in station mode (i.e., do the same that we are already doing in AP mode).

| * | | nl80211: improve station flags handlingJohannes Berg2009-05-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is currently not possible to modify station flags, but that capability would be very useful. This patch introduces a new nl80211 attribute that contains a set/mask for station flags, and updates the internal API (and mac80211) to mirror that. The new attribute is parsed before falling back to the old so that userspace can specify both (if it can) to work on all kernels.

| * | | cfg80211: implement wext key handlingJohannes Berg2009-05-13

Note that this drops the SIOCGIWENCODE ioctl support for getting IW_ENCODE_RESTRICTED/IW_ENCODE_OPEN. This means that iwconfig will no longer report "Security mode:open" or "Security mode:restricted" for mac80211. However, what we displayed there (the authentication algo used) was actually wrong -- linux/wireless.h states that this setting is meant to differentiate between "Refuse non-encoded packets" and "Accept non-encoded packets". (Combined with "cfg80211: fix a couple of bugs with key ioctls". -- JWL) Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| * | | nl80211 : Add support for configuring MFPJouni Malinen2009-05-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | NL80211_CMD_ASSOCIATE request must be able to indicate whether management frame protection (IEEE 802.11w) is being used. mac80211 was able to use MFP in client mode only with WEXT, but the new NL80211_ATTR_USE_MFP attribute will allow this to be done with nl80211, too. Since we are currently using nl80211 for MFP only with drivers that use user space SME, only MFP disabled and required values are used. However, the NL80211_ATTR_USE_MFP attribute is an enum that can be extended with MFP optional in the future, if that is needed with some drivers (e.g., if the RSN IE is generated by the driver).
