2009-07-10sched: optimize cond_resched()Peter Zijlstra
Optimize cond_resched() by removing one conditional. Currently cond_resched() checks system_state == SYSTEM_RUNNING in order to avoid scheduling before the scheduler is running. We can however, as per suggestion of Matt, use PREEMPT_ACTIVE to accomplish that very same.

Pull the initial preempt_count value into a single definition site. Maintainers for: alpha, ia64 and m68k, please have a look, your arch code is funny. The header magic is a bit odd, but similar to the KERNEL_DS one, CPP waits with expanding these macros until the INIT_THREAD_INFO macro itself is expanded, which is in arch/*/kernel/init_task.c where we've already included sched.h so we're good.

2009-07-10dma-debug: Fix the overlap() function to be correct and readableIngo Molnar
Linus noticed how unclean and buggy the overlap() function is: - It uses convoluted (and bug-causing) positive checks for range overlap - instead of using a more natural negative check. - Even the positive checks are buggy: a positive intersection check has four natural cases while we checked only for three, missing the (addr < start && addr2 == end) case for example. - The variables are mis-named, making it non-obvious how the check was done. - It needlessly uses u64 instead of unsigned long. Since these are kernel memory pointers and we explicitly exclude highmem ranges anyway we cannot ever overflow 32 bits, even if we could. (and on 64-bit it doesnt matter anyway) All in one, this function needs a total revamp. I used Linus's suggestions minus the paranoid checks (we cannot overflow really because if we get totally bad DMA ranges passed far more things break in the systems than just DMA debugging). I also fixed a few other small details i noticed. Reported-by: Linus Torvalds <torvalds@linux-foundation.org> Cc: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2009-07-10cfq-iosched: reset oom_cfqq in cfq_set_request()Vivek Goyal
In case memory is scarce, we now default to oom_cfqq. Once memory is available again, we should allocate a new cfqq and stop using oom_cfqq for a particular io context. Once a new request comes in, check if we are using oom_cfqq, and if yes, try to allocate a new cfqq. Tested the patch by forcing the use of oom_cfqq and upon next request thread realized that it was using oom_cfqq and it allocated a new cfqq.

2009-07-10block: fix sg SG_DXFER_TO_FROM_DEV regressionFUJITA Tomonori
I overlooked SG_DXFER_TO_FROM_DEV support when I converted sg to use the block layer mapping API (2.6.28). Douglas Gilbert explained SG_DXFER_TO_FROM_DEV: http://www.spinics.net/lists/linux-scsi/msg37135.html = The semantics of SG_DXFER_TO_FROM_DEV were: - copy user space buffer to kernel (LLD) buffer - do SCSI command which is assumed to be of the DATA_IN (data from device) variety. This would overwrite some or all of the kernel buffer - copy kernel (LLD) buffer back to the user space. The idea was to detect short reads by filling the original user space buffer with some marker bytes ("0xec" it would seem in this report). The "resid" value is a better way of detecting short reads but that was only added this century and requires co-operation from the LLD. = This patch changes the block layer mapping API to support this semantics. This simply adds another field to struct rq_map_data and enables __bio_copy_iov() to copy data from user space even with READ requests. It's better to add the flags field and kills null_mapped and the new from_user fields in struct rq_map_data but that approach makes it difficult to send this patch to stable trees because st and osst drivers use struct rq_map_data (they were converted to use the block layer in 2.6.29 and 2.6.30). Well, I should clean up the block layer mapping API. zhou sf reported this regiression and tested this patch: http://www.spinics.net/lists/linux-scsi/msg37128.html http://www.spinics.net/lists/linux-scsi/msg37168.html Reported-by: zhou sf <sxzzsf@gmail.com> Tested-by: zhou sf <sxzzsf@gmail.com> Cc: stable@kernel.org Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

2009-07-09cxgb3: Fix crash caused by stashing wrong netdev_queueRoland Dreier
Commit c3a8c5b6 ("cxgb3: move away from LLTX") exposed a bug in how cxgb3 looks up the netdev_queue it stashes away in a qset during initialization. For multiport devices, the TX queue index it uses is offset by the first_qset index of each port. This leads to a crash once LLTX is removed, since hard_start_xmit is called with one TX queue lock held, while the TX reclaim timer task grabs a different (wrong) TX queue lock when it frees skbs. Fix this by removing the first_qset offset used to look up the TX queue passed into t3_sge_alloc_qset() from setup_sge_qsets().

2009-07-09ixgbe: Fix coexistence of FCoE and Flow Director in 82599Yi Zou
Fix coexistence of Fiber Channel over Ethernet (FCoE) and Flow Director (FDIR) in 82599 and remove the disabling of FDIR when FCoE is enabled. Currently, FDIR is turned off when FCoE is enabled under the assumption that FCoE is always enabled with DCB being turned on. However, FDIR does not have to be turned off all the time when FCoE is enabled since FCoE can be enabled without DCB being turned on, e.g., use link pause only. This patch makes sure that when DCB is turned on or off, FDIR is turned on or off correspondingly; and when FCoE is enabled, it does not disable FDIR, rather, it will have FDIR set up properly so FCoE and FDIR can coexist regardless of DCB being on or off.

2009-07-09net: adding memory barrier to the poll and receive callbacksJiri Olsa
Adding memory barrier after the poll_wait function, paired with receive callbacks. Adding fuctions sock_poll_wait and sk_has_sleeper to wrap the memory barrier. Without the memory barrier, following race can happen. The race fires, when following code paths meet, and the tp->rcv_nxt and __add_wait_queue updates stay in CPU caches. CPU1 CPU2 sys_select receive packet ... ... __add_wait_queue update tp->rcv_nxt ... ... tp->rcv_nxt check sock_def_readable ... { schedule ... if (sk->sk_sleep && waitqueue_active(sk->sk_sleep)) wake_up_interruptible(sk->sk_sleep) ... } If there was no cache the code would work ok, since the wait_queue and rcv_nxt are opposit to each other. Meaning that once tp->rcv_nxt is updated by CPU2, the CPU1 either already passed the tp->rcv_nxt check and sleeps, or will get the new value for tp->rcv_nxt and will return with new data mask. In both cases the process (CPU1) is being added to the wait queue, so the waitqueue_active (CPU2) call cannot miss and will wake up CPU1. The bad case is when the __add_wait_queue changes done by CPU1 stay in its cache, and so does the tp->rcv_nxt update on CPU2 side. The CPU1 will then endup calling schedule and sleep forever if there are no more data on the socket.

Using early netconsole and gianfar driver this error pops up: netconsole: timeout waiting for carrier It appears that net/core/netpoll.c:netpoll_setup() is using cond_resched() in a loop waiting for a carrier. The thing is that cond_resched() is a no-op when system_state != SYSTEM_RUNNING, and so drivers/net/phy/phy.c's state_queue is never scheduled, therefore link detection doesn't work. I belive that the main problem is in cond_resched()[1], but despite how the cond_resched() story ends, it might be a good idea to call msleep(1) instead of cond_resched(), as suggested by Andrew Morton.

2009-07-08p54: tx refused but queue activeLarry Finger
In the mainline kernel, p54usb will fail because the TX queue length can become < 0. This problem has been reported as Bugzilla #13725. The failure is expressed by the following message in the logs: WARNING: at net/mac80211/tx.c:1325 ieee80211_tx+0x23c/0x298 [mac80211]() Hardware name: HP Pavilion dv2700 Notebook PC tx refused but queue active This problem has been recently observed in the wireless-testing tree, where a full solution is being tested. That fix is too invasive for 2.6.31-rcX, but the simple change supplied here will prevent the failure. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W.

2009-07-08Atheros Kconfig needs to be dependent on WLAN_80211Jay Sternberg
Atheros top level menu needs a "depends WLAN_80211" to properly indent within menuconfig and xconfig interfaces. This is purely a visual issue but it effects all subsequent drivers. The issue is the top level menu does not include a dependency on WLAN_80211 so within the tree structure, Atheros is at the same level as WLAN_80211 but when WLAN_80211 collapsed, the menu disappears along with all subsequent drives, so it is really a subordinate.

These two functions no longer exist in mac80211, so trying to insert them generates warnings in the document. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-07-08mac80211_hwsim: avoid NULL accessJohannes Berg
There's a race condition -- started can be set to true before channel is set due to the way mac80211 callbacks currently work (->start should probably pass the channel we would like to have initially). For now simply add a check to hwsim to avoid dereferencing the NULL channel pointer. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
