2008-11-19net: jme.c rxdesc.flags is __le16, other missing endian swapsHarvey Harrison
This is the minimal patch to fix endian mismatches. These are probably bugs on big-endian arches, noops on little endian. jme_rxsum_ok could be improved to directly take a __le16 and change all of the masks/sets to be in little-endian, but has not been done here to keep the patch small.

2008-11-18iwlagn: fix RX skb alignmentJohannes Berg
So I dug deeper into the DMA problems I had with iwlagn and a kind soul helped me in that he said something about pci-e alignment and mentioned the iwl_rx_allocate function to check for crossing 4KB boundaries. Since there's 8KB A-MPDU support, crossing 4k boundaries didn't seem like something the device would fail with, but when I looked into the function for a minute anyway I stumbled over this little gem: BUG_ON(rxb->dma_addr & (~DMA_BIT_MASK(36) & 0xff)); Clearly, that is a totally bogus check, one would hope the compiler removes it entirely. (Think about it) After fixing it, I obviously ran into it, nothing guarantees the alignment the way you want it, because of the way skbs and their headroom are allocated. I won't explain that here nor double-check that I'm right, that goes beyond what most of the CC'ed people care about. So then I came up with the patch below, and so far my system has survived minutes with 64K pages, when it would previously fail in seconds. And I haven't seen a single instance of the TX bug either. But when you see the patch it'll be pretty obvious to you why. This should fix the following reported kernel bugs: http://bugzilla.kernel.org/show_bug.cgi?id=11596 http://bugzilla.kernel.org/show_bug.cgi?id=11393 http://bugzilla.kernel.org/show_bug.cgi?id=11983 I haven't checked if there are any elsewhere, but I suppose RHBZ will have a few instances too... I'd like to ask anyone who is CC'ed (those are people I know ran into the bug) to try this patch. I am convinced that this patch is correct in spirit, but I haven't understood why, for example, there are so many unmap calls. I'm not entirely convinced that this is the only bug leading to the TX reply errors. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-11-18mac80211: remove ieee80211_notify_macJohannes Berg
Before ieee80211_notify_mac() was added, it was presented with the use case of using it to tell mac80211 that the association may have been lost because the firmware crashed/reset. Since then, it has also been used by iwlwifi to (slightly) speed up re-association after resume, a workaround around the fact that mac80211 has no suspend/resume handling yet. It is also not used by any other drivers, so clearly it cannot be necessary for "good enough" suspend/resume. Unfortunately, the callback suffers from a severe problem: It only works for station mode. If suspend/resume happens while in IBSS or any other mode (but station), then the callback is pointless. Recently, it has created a number of locking issues, first because it required rtnl locking rather than RCU due to calling sleeping functions within the critical section, and now because it's called by iwlwifi from the mac80211 workqueue that may not use the rtnl because it is flushed under rtnl. (cf. http://bugzilla.kernel.org/show_bug.cgi?id=12046) I think, therefore, that we should take a step back, remove it entirely for now and add the small feature it provided properly. For suspend and resume we will need to introduce new hooks, and for the case where the firmware was reset the driver will probably simply just pretend it has done a suspend/resume cycle to get mac80211 to reprogram the hardware completely, not just try to connect to the current AP again in station mode. When doing so, we will need to take into account locking issues and possibly defer to schedule_work from within mac80211 for the resume operation, while the suspend operation must be done directly. Proper suspend/resume should also not necessarily try to reconnect to the current AP, the time spent in suspend may have been short enough to not be disconnected from the AP, mac80211 will detect that the AP went out of range quickly if it did, and if the association is lost then the AP will disassoc as soon as a data frame is sent. We might also take into account WWOL then, and have mac80211 program the hardware into such a mode where it is available and requested.

Commit 46abc02175b3c246dd5141d878f565a8725060c9 ("phylib: give mdio buses a device tree presence") added a call to device_unregister() in a situation where the caller did not intend for the device to be freed yet, but apart from just unregistering the device from the system, device_unregister() does an additional put_device() that is intended to free it. The right function to use in this situation is device_del(), which unregisters the device from the system like device_unregister() does, but without dropping the reference count an additional time.

2008-11-12niu: Fix readq implementation when architecture does not provide one.David S. Miller
This fixes a TX hang reported by Jesper Dangaard Brouer. When an architecutre cannot provide a fully functional 64-bit atomic readq/writeq, the driver must implement it's own. This is because only the driver can say whether doing something like using two 32-bit reads to implement the full 64-bit read will actually work properly. In particular one of the issues is whether the top 32-bits or the bottom 32-bits of the 64-bit register should be read first. There could be side effects, and in fact that is exactly the problem here. The TX_CS register has counters in the upper 32-bits and state bits in the lower 32-bits. A read clears the state bits. We would read the counter half before the state bit half. That first read would clear the state bits, and then the driver thinks that no interrupts are pending because the interrupt indication state bits are seen clear every time. Fix this by reading the bottom half before the upper half. Tested-by: Jesper Dangaard Brouer <jdb@comx.dk> Signed-off-by: David S. Miller <davem@davemloft.net>

When the iw_cxgb3 module's cxgb3_client "add" func gets called by the cxgb3 module, the iwarp driver ends up calling the ethtool ops get_drvinfo function in cxgb3 to get the fw version and other info. Currently the iwarp driver grabs the rtnl lock around this down call to serialize. As of 2.6.27 or so, things changed such that the rtnl lock is held around the call to the netdev driver open function. Also the cxgb3_client "add" function doesn't get called if the device is down. So, if you load cxgb3, then load iw_cxgb3, then ifconfig up the device, the iw_cxgb3 add func gets called with the rtnl_lock held. If you load cxgb3, ifconfig up the device, then load iw_cxgb3, the add func gets called without the rtnl_lock held. The former causes the deadlock, the latter does not. In addition, there are iw_cxgb3 sysfs handlers that also can call down into cxgb3 to gather the fw and hw versions. These can be called concurrently on different processors and at any time. Thus we need to push this serialization down in the cxgb3 driver get_drvinfo func. The fix is to remove rtnl lock usage, and use a per-device lock in cxgb3.

2008-11-11myri10ge: fix stop/go ordering even moreBrice Goglin
The doorbell writes may be seen out of order by the firmware if they are in WC memory since the tx spin(un)lock does not flush WC writes. Hence if the "stop" is written on a different CPU than the "go", it is possible that the stop will arrive after the go unless we add an explicit memory barrier (and mmiowb() is not enough). It fixes transmit hangs in multi tx queue mode. Signed-off-by: Brice Goglin <brice@myri.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2008-11-07[netdrvr] usb/hso: Cleanup rfkill error handlingJonathan McDowell
Yup, this appears to be the problem, thanks. I think &hso_net->net->dev is more intuitive for the error message, so I've used that. I've also added missing line endings on the error messages and set our local rfkill structure element to NULL on failure so we don't try to call rfkill_unregister on driver removal if we failed to register at all. The patch below Works For Me (TM); the device is detected fine, can be removed without problems and connects ok. I'll have a prod at why the rfkill stuff isn't working next, but I believe this cleanup of the error handling is appropriate no matter what the issue with registration is.
