2010-10-05NULL pointer might be used in ips_monitor()minskey guo1-9/+13
The patch is to create ips_adjust thread before ips_monitor begins to run because the latter will kthread_stop() or wake up the former via ips->adjust pointer. Without this change, it is possible that ips->adjust is NULL when kthread_stop() or wake_up_process() is called in ips_monitor().

2010-10-05wait: using uninitialized member of wait queueEvgeny Kuznetsov1-0/+1
The "flags" member of "struct wait_queue_t" is used in several places in the kernel code without beeing initialized by init_wait(). "flags" is used in bitwise operations. If "flags" not initialized then unexpected behaviour may take place. Incorrect flags might used later in code. Added initialization of "wait_queue_t.flags" with zero value into "init_wait". Signed-off-by: Evgeny Kuznetsov <[email protected]> [ The bit we care about does end up being initialized by both prepare_to_wait() and add_to_wait_queue(), so this doesn't seem to cause actual bugs, but is definitely the right thing to do -Linus ] Signed-off-by: Linus Torvalds <[email protected]>
2010-10-05modules: Fix module_bug_list list corruption raceLinus Torvalds11-26/+14
With all the recent module loading cleanups, we've minimized the code that sits under module_mutex, fixing various deadlocks and making it possible to do most of the module loading in parallel. However, that whole conversion totally missed the rather obscure code that adds a new module to the list for BUG() handling. That code was doubly obscure because (a) the code itself lives in lib/bugs.c (for dubious reasons) and (b) it gets called from the architecture-specific "module_finalize()" rather than from generic code. Calling it from arch-specific code makes no sense what-so-ever to begin with, and is now actively wrong since that code isn't protected by the module loading lock any more. So this commit moves the "module_bug_{finalize,cleanup}()" calls away from the arch-specific code, and into the generic code - and in the process protects it with the module_mutex so that the list operations are now safe. Future fixups: - move the module list handling code into kernel/module.c where it belongs. - get rid of 'module_bug_list' and just use the regular list of modules (called 'modules' - imagine that) that we already create and maintain for other reasons.

2010-10-05omap: iommu-load cam register before flushing the entryHari Kanigeri1-0/+1
The flush_iotlb_page is not loading the cam register before flushing the cam entry. This causes wrong entry to be flushed out from the TLB, and if the entry happens to be a locked TLB entry it would lead to MMU faults. The fix is to load the cam register with the address to be flushed before flushing the TLB entry.

2010-10-05xen: do not initialize PV timers on HVM if !xen_have_vector_callbackStefano Stabellini1-2/+3
if !xen_have_vector_callback do not initialize PV timer unconditionally because we still don't know how many cpus are available and if there is more than one we won't be able to receive the timer interrupts on cpu > 0.

2010-10-05xen: do not set xenstored_ready before xenbus_probe on hvmStefano Stabellini1-3/+6
Register_xenstore_notifier should guarantee that the caller gets notified even if xenstore is already up. Therefore we revert "do not notify callers from register_xenstore_notifier" and set xenstored_read at the right time for PV on HVM guests too. In fact in case of PV on HVM guests xenstored is ready only after the platform pci driver has completed the initialization, so do not set xenstored_ready before the call to xenbus_probe(). This patch fixes a shutdown_event watcher registration bug that causes "xm shutdown" not to work properly.

2010-10-04ksm: fix bad user data when swappingHugh Dickins1-2/+4
Building under memory pressure, with KSM on 2.6.36-rc5, collapsed with an internal compiler error: typically indicating an error in swapping. Perhaps there's a timing issue which makes it now more likely, perhaps it's just a long time since I tried for so long: this bug goes back to KSM swapping in 2.6.33. Notice how reuse_swap_page() allows an exclusive page to be reused, but only does SetPageDirty if it can delete it from swap cache right then - if it's currently under Writeback, it has to be left in cache and we don't SetPageDirty, but the page can be reused. Fine, the dirty bit will get set in the pte; but notice how zap_pte_range() does not bother to transfer pte_dirty to page_dirty when unmapping a PageAnon. If KSM chooses to share such a page, it will look like a clean copy of swapcache, and not be written out to swap when its memory is needed; then stale data read back from swap when it's needed again. We could fix this in reuse_swap_page() (or even refuse to reuse a page under writeback), but it's more honest to fix my oversight in KSM's write_protect_page(). Several days of testing on three machines confirms that this fixes the issue they showed.

2010-10-04ksm: fix page_address_in_vma anon_vma oopsHugh Dickins1-1/+7
2.6.36-rc1 commit 21d0d443cdc1658a8c1484fdcece4803f0f96d0e "rmap: resurrect page_address_in_vma anon_vma check" was right to resurrect that check; but now that it's comparing anon_vma->roots instead of just anon_vmas, there's a danger of oopsing on a NULL anon_vma. In most cases no NULL anon_vma ever gets here; but it turns out that occasionally KSM, when enabled on a forked or forking process, will itself call page_address_in_vma() on a "half-KSM" page left over from an earlier failed attempt to merge - whose page_anon_vma() is NULL. It's my bug that those should be getting here at all: I thought they were already dealt with, this oops proves me wrong, I'll fix it in the next release - such pages are effectively pinned until their process exits, since rmap cannot find their ptes (though swapoff can). For now just work around it by making page_address_in_vma() safe (and add a comment on why that check is wanted anyway). A similar check in __page_check_anon_rmap() is safe because do_page_add_anon_rmap() already excluded KSM pages.
