2008-09-08mac80211: Fix rate scale initialization in IBSSEmmanuel Grumbach
This patch address some IBSS rate issues introduced or not covered by "mac80211: eliminate IBSS warning in rate_lowest_index()" and "cfg80211 API for channels/bitrates, mac80211 and driver conversion". This patch: 1. Moves addition of IBSS station from prepare_for_handlers to ieee80211_rx_bss_info when triggered from beacon eliminating bogus supported rates. 2. Initialize properly supported rates also in IBSS merging 3. Ensure that mandatory rates are always added into supported rates. This is needed in case when station addition is triggered from non beacon/probe packet. Some management frames need to be sent 4. Remove initialization of supported rates from self rates. This path was dead code after 6bc37c06bc4 and in general incorrect.

2008-09-08mac80211: Fix low bit rate in IBSSTomas Winkler
This patch fixes regression in iwlwifi IBSS rate scaling caused by patch: commit 6bc37c06bc424bcf3f944e6a79e2d5bb537e02ed Author: Vladimir Koutny <vlado@work.ksp.sk> Date: Fri Jun 13 16:50:44 2008 +0200 mac80211: eliminate IBSS warning in rate_lowest_index() An IBSS station is added in prepare_for_handlers where the rate scaling was initialized only with single rate matching the received packet. The correct rate scale information should be updated only in ieee80211_rx_bss_info function where beacon is parsed. Because of coding error the rate info was left untouched. If a beacon has triggered the connection the rate remined 1Mbps.

This patch hopefully contains all necessary changes to support firmwares for all devices up to atleast 2.13.3.0. (or: LowerMAC Protocol Rev: 5.5 ) And this is a big win, since: * newer firmwares are more stable and reliable than the old ones. * no problems anymore with packages > 1399 octets (without lowering the MTU). * monitor mode finally works on USB for more than just a few seconds.

2008-09-08libata-sff: kill spurious WARN_ON() in ata_hsm_move()Tejun Heo
On HSM_ST_ERR, ata_hsm_move() triggers WARN_ON() if AC_ERR_DEV or AC_ERR_HSM is not set. PHY events may trigger HSM_ST_ERR with other error codes and, with or without it, there just isn't much reason to do WARN_ON() on it. Even if error code is not set there, core EH logic won't have any problem dealing with the error condition. OSDL bz#11065 reports this problem.

2008-09-08sata_nv: disable hardreset for genericTejun Heo
of them being unifying probing, hotplug and EH reset paths uniform. Previously, broken hardreset could go unnoticed as it wasn't used during probing but when something goes wrong or after hotplug the problem will surface and bite hard. OSDL bug 11195 reports that sata_nv generic flavor falls into this category. Hardreset itself succeeds but PHY stays offline after hardreset. I tried longer debounce timing but the result was the same. http://bugzilla.kernel.org/show_bug.cgi?id=11195 So, it seems we'll have to drop hardreset from the generic flavor.

2008-09-08ahci, pata_marvell: play nicely togetherAlan Cox
I've been chasing Jeff about this for months. Jeff added the Marvell device identifiers to the ahci driver without making the AHCI driver handle the PATA port. This means a lot of users can't use current kernels and in most distro cases can't even install. This has been going on since March 2008 for the 6121 Marvell, and late 2007 for the 6145!!! This was all pointed out at the time and repeatedly ignored. Bugs assigned to Jeff about this are ignored also. To quote Jeff in email > "Just switch the order of 'ahci' and 'pata_marvell' in > /etc/modprobe.conf, then use Fedora's tools regenerate the initrd. > See? It's not rocket science, and the current configuration can be > easily made to work for Fedora users." (Which isn't trivial, isn't end user, shouldn't be needed, and as it usually breaks at install time is in fact impossible) To quote Jeff in August 2007 > " mv-ahci-pata > Marvell 6121/6141 PATA support. Needs fixing in the 'PATA controller > command' area before it is usable, and can go upstream." Only he add the ids anyway later and caused regressions, adding a further id in March causing more regresions. The actual fix for the moment is very simple. If the user has included the pata_marvell driver let it drive the ports. If they've only selected for SATA support give them the AHCI driver which will run the port a fraction faster. Allow the user to control this decision via ahci.marvell_enable as a module parameter so that distributions can ship 'it works' defaults and smarter users (or config tools) can then flip it over it desired.

2008-09-07netfilter: nf_conntrack_irc: make sure string is terminated before calling ↵Patrick McHardy
simple_strtoul Alexey Dobriyan points out: 1. simple_strtoul() silently accepts all characters for given base even if result won't fit into unsigned long. This is amazing stupidity in itself, but 2. nf_conntrack_irc helper use simple_strtoul() for DCC request parsing. Data first copied into 64KB buffer, so theoretically nothing prevents reading past the end of it, since data comes from network given 1). This is not actually a problem currently since we're guaranteed to have a 0 byte in skb_shared_info or in the buffer the data is copied to, but to make this more robust, make sure the string is actually terminated.

2008-09-08powerpc/spufs: Fix possible scheduling of a context to multiple SPEsAndre Detsch
We currently have a race when scheduling a context to a SPE - after we have found a runnable context in spusched_tick, the same context may have been scheduled by spu_activate(). This may result in a panic if we try to unschedule a context that has been freed in the meantime. This change exits spu_schedule() if the context has already been scheduled, so we don't end up scheduling it twice.

2008-09-06sched: arch_reinit_sched_domains() must destroy domains to force rebuildMax Krasnyansky
What I realized recently is that calling rebuild_sched_domains() in arch_reinit_sched_domains() by itself is not enough when cpusets are enabled. partition_sched_domains() code is trying to avoid unnecessary domain rebuilds and will not actually rebuild anything if new domain masks match the old ones. What this means is that doing echo 1 > /sys/devices/system/cpu/sched_mc_power_savings on a system with cpusets enabled will not take affect untill something changes in the cpuset setup (ie new sets created or deleted). This patch fixes restore correct behaviour where domains must be rebuilt in order to enable MC powersaving flags. Test on quad-core Core2 box with both CONFIG_CPUSETS and !CONFIG_CPUSETS. Also tested on dual-core Core2 laptop. Lockdep is happy and things are working as expected.
