2007-11-09sched: fix delay accounting regressionBalbir Singh
Fix the delay accounting regression introduced by commit 75d4ef16a6aa84f708188bada182315f80aab6fa. rq no longer has sched_info data associated with it. task_struct sched_info structure is used by delay accounting to provide back statistics to user space. also remove direct use of sched_clock() (which is not a valid thing to do anymore) and use rq->clock instead.

2007-11-09sched: reintroduce the sched_min_granularity tunablePeter Zijlstra
we lost the sched_min_granularity tunable to a clever optimization that uses the sched_latency/min_granularity ratio - but the ratio is quite unintuitive to users and can also crash the kernel if the ratio is set to 0. So reintroduce the min_granularity tunable, while keeping the ratio maintained internally. no functionality changed.

2007-10-24sched: reduce balance-tasks overheadPeter Williams
At the moment, balance_tasks() provides low level functionality for both move_tasks() and move_one_task() (indirectly) via the load_balance() function (in the sched_class interface) which also provides dual functionality. This dual functionality complicates the interfaces and internal mechanisms and makes the run time overhead of operations that are called with two run queue locks held.

2007-10-24sched: use show_regs() to improve __schedule_bug() outputSatyam Sharma
A full register dump along with stack backtrace would make the "scheduling while atomic" message more helpful. Use show_regs() instead of dump_stack() for this. We already know we're atomic in here (that is why this function was called) so show_regs()'s atomicity expectations are guaranteed. Also, modify the output of the "BUG: scheduling while atomic:" header a bit to keep task->comm and task->pid together and preempt_count() after them.

2007-10-24sched: fix sched_domain sysctl registration againMilton Miller
commit 029190c515f15f512ac85de8fc686d4dbd0ae731 (cpuset sched_load_balance flag) was not tested SCHED_DEBUG enabled as committed as it dereferences NULL when used and it reordered the sysctl registration to cause it to never show any domains or their tunables. Fixes: 1) restore arch_init_sched_domains ordering we can't walk the domains before we build them presently we register cpus with empty directories (no domain directories or files). 2) make unregister_sched_domain_sysctl do nothing when already unregistered detach_destroy_domains is now called one set of cpus at a time unregister_syctl dereferences NULL if called with a null. While the the function would always dereference null if called twice, in the previous code it was always called once and then was followed a register. So only the hidden bug of the sysctl_root_table not being allocated followed by an attempt to free it would have shown the error. 3) always call unregister and register in partition_sched_domains The code is "smart" about unregistering only needed domains. Since we aren't guaranteed any calls to unregister, always unregister. Without calling register on the way out we will not have a table or any sysctl tree. 4) warn if register is called without unregistering The previous table memory is lost, leaving pointers to the later freed memory in sysctl and leaking the memory of the tables. Before this patch on a 2-core 4-thread box compiled for SMT and NUMA, the domains appear empty (there are actually 3 levels per cpu). And as soon as two domains a null pointer is dereferenced (unreliable in this case is stack garbage): bu19a:~# ls -R /proc/sys/kernel/sched_domain/ /proc/sys/kernel/sched_domain/: cpu0 cpu1 cpu2 cpu3 /proc/sys/kernel/sched_domain/cpu0: /proc/sys/kernel/sched_domain/cpu1: /proc/sys/kernel/sched_domain/cpu2: /proc/sys/kernel/sched_domain/cpu3: bu19a:~# mkdir /dev/cpuset bu19a:~# mount -tcpuset cpuset /dev/cpuset/ bu19a:~# cd /dev/cpuset/ bu19a:/dev/cpuset# echo 0 > sched_load_balance bu19a:/dev/cpuset# mkdir one bu19a:/dev/cpuset# echo 1 > one/cpus bu19a:/dev/cpuset# echo 0 > one/sched_load_balance Unable to handle kernel paging request for data at address 0x00000018 Faulting instruction address: 0xc00000000006b608 NIP: c00000000006b608 LR: c00000000006b604 CTR: 0000000000000000 REGS: c000000018d973f0 TRAP: 0300 Not tainted (2.6.23-bml) MSR: 9000000000009032 <EE,ME,IR,DR> CR: 28242442 XER: 00000000 DAR: 0000000000000018, DSISR: 0000000040000000 TASK = c00000001912e340[1987] 'bash' THREAD: c000000018d94000 CPU: 2 ..

2007-10-23Fix synchronize_irq races with IRQ handlerHerbert Xu
As it is some callers of synchronize_irq rely on memory barriers to provide synchronisation against the IRQ handlers. For example, the tg3 driver does tp->irq_sync = 1; smp_mb(); synchronize_irq(); and then in the IRQ handler: if (!tp->irq_sync) netif_rx_schedule(dev, &tp->napi); Unfortunately memory barriers only work well when they come in pairs. Because we don't actually have memory barriers on the IRQ path, the memory barrier before the synchronize_irq() doesn't actually protect us. In particular, synchronize_irq() may return followed by the result of netif_rx_schedule being made visible. This patch (mostly written by Linus) fixes this by using spin locks instead of memory barries on the synchronize_irq() path.

2007-10-21[PATCH] audit: watching subtreesAl Viro
New kind of audit rule predicates: "object is visible in given subtree". The part that can be sanely implemented, that is. Limitations: * if you have hardlink from outside of tree, you'd better watch it too (or just watch the object itself, obviously) * if you mount something under a watched tree, tell audit that new chunk should be added to watched subtrees * if you umount something in a watched tree and it's still mounted elsewhere, you will get matches on events happening there. New command tells audit to recalculate the trees, trimming such sources of false positives. Note that it's _not_ about path - if something mounted in several places (multiple mount, bindings, different namespaces, etc.), the match does _not_ depend on which one we are using for access.
