* mac80211/drivers: rewrite the rate control APIJohannes Berg2008-11-011-98/+156
| | | | | | | | | | | | So after the previous changes we were still unhappy with how convoluted the API is and decided to make things simpler for everybody. This completely changes the rate control API, now taking into account 802.11n with MCS rates and more control, most drivers don't support that though.

* mac80211: rewrite HT handlingJohannes Berg2008-11-011-33/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The HT handling has the following deficiencies, which I've (partially) fixed: * it always uses the AP info even if there is no AP, hence has no chance of working as an AP * it pretends to be HW config, but really is per-BSS * channel sanity checking is left to the drivers * it generally lets the driver control too much HT enabling is still wrong with this patch if you have more than one virtual STA mode interface, but that never happens currently. Once WDS, IBSS or AP/VLAN gets HT capabilities, it will also be wrong, see the comment in ieee80211_enable_ht(). Additionally, this fixes a number of bugs: * mac80211: ieee80211_set_disassoc doesn't notify the driver any more since the refactoring * iwl-agn-rs: always uses the HT capabilities from the wrong stuff mac80211 gives it rather than the actual peer STA * ath9k: a number of bugs resulting from the broken HT API I'm not entirely happy with putting the HT capabilities into struct ieee80211_sta as restricted to our own HT TX capabilities, but I see no cleaner solution for now.

* pkt_sched: Add peek emulation for non-work-conserving qdiscs.Jarek Poplawski2008-10-311-0/+23
| | | | | | | | | | | | | | | This patch adds qdisc_peek_dequeued() wrapper to emulate peek method with qdisc->dequeue() and storing "peeked" skb in qdisc->gso_skb until dequeuing. This is mainly for compatibility reasons not to break some strange configs because peeking is expected for non-work-conserving parent qdiscs to query work-conserving child qdiscs. This implementation requires using qdisc_dequeue_peeked() wrapper instead of directly calling qdisc->dequeue() for all qdiscs ever querried with qdisc->ops->peek() or qdisc_peek_dequeued().

| | | | | | | | | | | | | | | From: Patrick McHardy <kaber@trash.net> Just as a demonstration how easy adding a peek operation to the work-conserving qdiscs actually is. It doesn't need to keep or change any internal state in many cases thanks to the guarantee that the packet will either be dequeued or, if another packet arrives, the upper qdisc will immediately ->peek again to reevaluate the state.

| | * gianfar: Fix race in TBI/SerDes configurationTrent Piepho2008-10-311-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The init_phy() function attaches to the PHY, then configures the SerDes<->TBI link (in SGMII mode). The TBI is on the MDIO bus with the PHY (sort of) and is accessed via the gianfar's MDIO registers, using the functions gfar_local_mdio_read/write(), which don't do any locking. The previously attached PHY will start a work-queue on a timer, and probably an irq handler as well, which will talk to the PHY and thus use the MDIO bus. This uses phy_read/write(), which have locking, but not against the gfar_local_mdio versions. The result is that PHY code will try to use the MDIO bus at the same time as the SerDes setup code, corrupting the transfers. Setting up the SerDes before attaching to the PHY will insure that there is no race between the SerDes code and *our* PHY, but doesn't fix everything. Typically the PHYs for all gianfar devices are on the same MDIO bus, which is associated with the first gianfar device. This means that the first gianfar's SerDes code could corrupt the MDIO transfers for a different gianfar's PHY. The lock used by phy_read/write() is contained in the mii_bus structure, which is pointed to by the PHY. This is difficult to access from the gianfar drivers, as there is no link between a gianfar device and the mii_bus which shares the same MDIO registers. As far as the device layer and drivers are concerned they are two unrelated devices (which happen to share registers). Generally all gianfar devices' PHYs will be on the bus associated with the first gianfar. But this might not be the case, so simply locking the gianfar's PHY's mii bus might not lock the mii bus that the SerDes setup code is going to use. We solve this by having the code that creates the gianfar platform device look in the device tree for an mdio device that shares the gianfar's registers. If one is found the ID of its platform device is saved in the gianfar's platform data. A new function in the gianfar mii code, gfar_get_miibus(), can use the bus ID to search through the platform devices for a gianfar_mdio device with the right ID. The platform device's driver data is the mii_bus structure, which the SerDes setup code can use to lock the current bus.

The Linux kernel defaulted to 32k (on a 4k page size system) to accommodate the needs of gpg. However, newer gpg2 needs 64k in various circumstances and otherwise fails miserably, see bnc#329675. Change the default to 64k, and make it more agnostic to PAGE_SIZE.

The record ip function would place the calling address (ip) into the hash. The daemon would later read the hash and modify that code. The hash complicates the code. This patch removes it.

Right now we have two functions: ftrace_kill and ftrace_kill_atomic. The ftrace_kill tries to do it in a "nice" way by converting everything back to a nop. The "nice" way is dangerous itself, so this patch removes it and only has the "atomic" version, which is all that is needed.

The other two names that are offspring from FTRACE DYNAMIC_FTRACE and FTRACE_MCOUNT_RECORD will stay the same. This patch was generated mostly by script, and partially by hand.
