From b0f70292053a0f68f406564a721a7a3f2d66b44f Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Mon, 2 Jan 2012 08:41:23 +0100 Subject: ssb: SPROM: extract each core power info MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We already extract some basic info but it's incomplete, reads info about the first core only. Used data structure doesn't allow easy adding of more cores. This patch adds new struct and array for storing power info. The plan is to: switch all extractors (including the ones using NVRAM) to new struct, switch drivers, then deprecate and finally drop old SSB fields.

The driver is only notified when the station is actually in the mac80211 hash table, not for pre-insert state transitions. To allow the driver to replace sta_add/remove calls with this, call extra transitions with the NOTEXIST state. This callback can fail, so we need to be careful in handling it when a station is inserted, particularly in the IBSS case where we still keep the station entry around for mac80211 purposes.

It is possible to have out of band authentication (FT), tracking multiple authentications caused more problems than it ever helped, and the implementation in mac80211 is too complex. Remove all this complexity, and let userspace do whatever it wants to, mac80211 can deal with that just fine. Association is still tracked of course, but authentication no longer is. Local auth state changes are thus no longer of value, so ignore them completely. This will also help implement SAE -- asking the driver to do an authentication is now almost equivalent to sending an authentication frame, with the exception of shared key authentication which is still handled completely.

When the qdisc receives a plug command via netlink request, packets arriving henceforth are buffered until a corresponding unplug command is received. Depending on the type of unplug command, the queue can be unplugged indefinitely or selectively. This qdisc can be used to implement output buffering, an essential functionality required for consistent recovery in checkpoint based fault-tolerance systems. Output buffering enables speculative execution by allowing generated network traffic to be rolled back. It is used to provide network protection for Xen Guests in the Remus high availability project, available as part of Xen. This module is generic enough to be used by any other system that wishes to add speculative execution and output buffering to its applications. This module was originally available in the linux 2.6.32 PV-OPS tree, used as dom0 for Xen. For more information, please refer to http://nss.cs.ubc.ca/remus/ and http://wiki.xensource.com/xenwiki/Remus Changes in V3: * Removed debug output (printk) on queue overflow * Added TCQ_PLUG_RELEASE_INDEFINITE - that allows the user to use this qdisc, for simple plug/unplug operations. * Use of packet counts instead of pointers to keep track of the buffers in the queue.

Hoover" Date: Wed, 8 Feb 2012 09:11:07 +0000 Subject: ipv4: Implement IP_UNICAST_IF socket option. The IP_UNICAST_IF feature is needed by the Wine project. This patch implements the feature by setting the outgoing interface in a similar fashion to that of IP_MULTICAST_IF. A separate option is needed to handle this feature since the existing options do not provide all of the characteristics required by IP_UNICAST_IF, a summary is provided below. SO_BINDTODEVICE: * SO_BINDTODEVICE requires administrative privileges, IP_UNICAST_IF does not. From reading some old mailing list articles my understanding is that SO_BINDTODEVICE requires administrative privileges because it can override the administrator's routing settings. * The SO_BINDTODEVICE option restricts both outbound and inbound traffic, IP_UNICAST_IF only impacts outbound traffic. IP_PKTINFO: * Since IP_PKTINFO and IP_UNICAST_IF are independent options, implementing IP_UNICAST_IF with IP_PKTINFO will likely break some applications. * Implementing IP_UNICAST_IF on top of IP_PKTINFO significantly complicates the Wine codebase and reduces the socket performance (doing this requires a lot of extra communication between the "server" and "user" layers). bind(): * bind() does not work on broadcast packets, IP_UNICAST_IF is specifically intended to work with broadcast packets. * Like SO_BINDTODEVICE, bind() restricts both outbound and inbound traffic.

The mechanism is there, IP_PKTOPTIONS getsockopt with IP_RECVTOS set, the same way as incoming TTL can be queried. This is not actually implemented for TOS, though. This patch adds this functionality, both for IPv4 (IP_PKTOPTIONS) and IPv6 (IPV6_2292PKTOPTIONS). For IPv4, like in the IP_RECVTTL case, the value of the TOS field is stored from the other party's ACK. This is needed for proxies which require DSCP transparency.

Small fix for ixgbevf_probe(): if ixgbevf_sw_init() fails (which means the device got no dev_addr) handle the error and jump to err_sw_init as already done by igbvf in similar case.

This way, we cannot directly call hci_do_le_scan() to scan LE devices in start_discovery(). To overcome this issue a derefered work (hdev->le_scan) was created so we can properly call hci_do_le_scan(). The helper function hci_le_scan() simply set LE scan parameters and queue hdev->le_scan work. The work is queued on system_long_wq since it can sleep for a few seconds in the worst case (timeout).

Moreover, merging this two states will simplify the discovery state machine and will keep interleaved discovery implementation simpler.

When non-peeking recvmsg occurs and the peeking offset is non negative is is moved backward so that the next peek will still peek the proper data (i.e. the one that would have been picked if there were no non peeking recv in between). The offset is set using per-proto opteration to let the protocol handle the locking issues and to check whether the peeking offset feature is supported by the protocol the socket belongs to.

Overall, this makes it much clearer what's going on in the API. Kalle developed the ath6kl changes, I created the rest of the patch.

The code did not treat the initial sequence numbers ISS and ISR as read-only and did not keep state for GSR and GSS as required by the specification. This causes problems with retransmissions during the initial handshake, causing the budding connection to be reset. This patch now treats ISS/ISR as read-only and tracks GSS/GSR as required.

The new file has my copyright since I designed and implemented the ppp_generic interface in the late 1990s. None of the contents of this file comes from the original if_ppp.h published by Carnegie Mellon University. Of the remainder of if_ppp.h, only the PPP_MTU definition was being used, and this replaces the uses of it with PPP_MRU (which is identical). Therefore, this replaces the entire file with the single line #include which clearly doesn't contain any CMU code. Thus I have removed the CMU copyright notice with its problematic advertising clause, and in fact since it's only one trivial line I have not added any other copyright notice.

I suspect this is due to the __QUEUE_STATE_STACK_XOFF bit being set prior to a reset for link change, and then not being cleared by netdev_tx_reset_queue. This change corrects that. In addition we were seeing dev_watchdog hangs on igb after running the ethtool tests. We found this to be due to the fact that the ethtool test runs the same logic as ndo_start_xmit, but we were never clearing the XOFF flag since the loopback test in ethtool does not do byte queue accounting.

This seems wrong, as it implies that either none or all of the network interfaces accept gratuitous arps. This patch corrects that, allowing per-interface arp_accept configuration to deviate from the all setting. Note this also brings us into line with the way the arp_filter setting is handled during arp_process execution. Tested this myself on my home network, and confirmed it works as expected.

Some devices happen to use fat skbs (truesize of 4096 + sizeof(struct sk_buff)) to store regular (MTU <= 1500) frames. This makes highly probable sk_rmem_alloc hits sk_rcvbuf limit, which can be 4Mbytes in many cases. When limit is hit, tcp stack calls tcp_collapse_ofo_queue(), a true latency killer and cpu cache blower. Doing the coalescing attempt each time we add a frame in ofo queue permits to keep memory use tight and in many cases avoid the tcp_collapse() thing later. Tested on various wireless setups (b43, ath9k, ...) known to use big skb truesize, this patch removed the "packets collapsed in receive queue due to low socket buffer" I had before. This also reduced average memory used by tcp sockets. With help from Neal Cardwell. Signed-off-by: Eric Dumazet Cc: Neal Cardwell Cc: Yuchung Cheng Cc: H.K.
