2012-12-13md: Update checkpoint of resync/recovery based on time.majianpeng1-0/+5
md will current only only checkpoint recovery or resync ever 1/16th of the device size. As devices get larger this can become a long time an so a lot of work that might need to be duplicated after a shutdown. So add a time-based checkpoint. Every 5 minutes limits the amount of duplicated effort to at most 5 minutes, and has almost zero impact on performance.

2012-12-11md: close race between removing and adding a device.NeilBrown1-0/+6
When we remove a device from an md array, the final removal of the "dev-XX" sys entry is run asynchronously. If we then re-add that device immediately before the worker thread gets to run, we can end up trying to add the "dev-XX" sysfs entry back before it has been removed. So in both places where we add a device, call flush_workqueue(md_misc_wq); before taking the md lock (as holding the md lock can prevent removal to complete). Signed-off-by: NeilBrown <neilb@suse.de>

2012-11-27md/raid1{,0}: fix deadlock in bitmap_unplug.NeilBrown2-2/+2
If the raid1 or raid10 unplug function gets called from a make_request function (which is very possible) when there are bios on the current->bio_list list, then it will not be able to successfully call bitmap_unplug() and it could need to submit more bios and wait for them to complete. But they won't complete while current->bio_list is non-empty. So detect that case and handle the unplugging off to another thread just like we already do when called from within the scheduler. RAID1 version of bug was introduced in 3.6, so that part of fix is suitable for 3.6.y. RAID10 part won't apply.

2012-11-22md/raid10: decrement correct pending counter when writing to replacement.NeilBrown1-1/+1
When a write to a replacement device completes, we carefully and correctly found the rdev that the write actually went to and the blithely called rdev_dec_pending on the primary rdev, even if this write was to the replacement. This means that any writes to an array while a replacement was ongoing would cause the nr_pending count for the primary device to go negative, so it could never be removed. This bug has been present since replacement was introduced in 3.3, so it is suitable for any -stable kernel since then.

2012-11-22md/raid10: close race that lose writes lost when replacement completes.NeilBrown1-61/+68
When a replacement operation completes there is a small window when the original device is marked 'faulty' and the replacement still looks like a replacement. The faulty should be removed and the replacement moved in place very quickly, bit it isn't instant. So the code write out to the array must handle the possibility that the only working device for some slot in the replacement - but it doesn't. If the primary device is faulty it just gives up. This can lead to corruption. So make the code more robust: if either the primary or the replacement is present and working, write to them. Only when neither are present do we give up. This bug has been present since replacement was introduced in 3.3, so it is suitable for any -stable kernel since then.

2012-11-22md/raid5: Make sure we clear R5_Discard when discard is finished.NeilBrown1-2/+5
commit 9e44476851e91c86c98eb92b9bc27fb801f89072 MD: raid5 avoid unnecessary zero page for trim change raid5 to clear R5_Discard when the complete request is handled rather than when submitting the per-device discard request. However it did not clear R5_Discard for the parity device. This means that if the stripe_head was reused before it expired from the cache, the setting would be wrong and a hang would result. Also if the R5_Uptodate bit happens to be set, R5_Discard again won't be cleared. But R5_Uptodate really should be clear at this point. So make sure R5_Discard is cleared in all cases, and clear R5_Uptodate when a 'discard' completes. Signed-off-by: NeilBrown <neilb@suse.de>
2012-11-22md/raid5: move resolving of reconstruct_state earlier inNeilBrown1-34/+34
stripe_handle. The chunk of code in stripe_handle which responds to a *_result value in reconstruct_state is really the completion of some processing that happened outside of handle_stripe (possibly asynchronously) and so should be one of the first things done in handle_stripe(). After the next patch it will be important that it happens before handle_stripe_clean_event(), as that will clear some dev->flags bit that this code tests. Signed-off-by: NeilBrown <neilb@suse.de>

2012-10-31MD RAID10: Fix oops when creating RAID10 arrays via dm-raid.cJonathan Brassow1-6/+9
Commit 2863b9eb didn't take into account the changes to add TRIM support to RAID10 (commit 532a2a3fb). That is, when using dm-raid.c to create the RAID10 arrays, there is no mddev->gendisk or mddev->queue. The code added to support TRIM simply assumes that mddev->queue is available without checking. The result is an oops any time dm-raid.c attempts to create a RAID10 device. Signed-off-by: Jonathan Brassow <jbrassow@redhat.com> Signed-off-by: NeilBrown <neilb@suse.de>
2012-10-31md/raid1: Fix assembling of arrays containing Replacements.NeilBrown1-1/+1
setup_conf in raid1.c uses conf->raid_disks before assigning a value. It is used when including 'Replacement' devices. The consequence is that assembling an array which contains a replacement will misbehave and either not include the replacement, or not include the device being replaced. Though this doesn't lead directly to data corruption, it could lead to reduced data safety. So use mddev->raid_disks, which is initialised, instead. Bug was introduced by commit c19d57980b38a5bb613a898937a1cf85f422fb9b md/raid1: recognise replacements when assembling arrays. in 3.3, so fix is suitable for 3.3.y thru 3.6.y.

2012-10-22md faulty: use disk_stack_limits()Eric Sandeen1-1/+4
in: fe86cdce block: do not artificially constrain max_sectors for stacking drivers max_sectors defaults to UINT_MAX. md faulty wasn't using disk_stack_limits(), so inherited this large value as well. This triggered a bug in XFS when stressed over md_faulty, when a very large bio_alloc() failed. That was on an older kernel, and I can't reproduce exactly the same thing upstream, but I think the fix is appropriate in any case. Thanks to Mike Snitzer for pointing out the problem.

2012-10-14x86, boot: Explicitly include autoconf.h for hostprogsMatt Fleming1-1/+2
The hostprogs need access to the CONFIG_* symbols found in include/generated/autoconf.h. But commit abbf1590de22 ("UAPI: Partition the header include path sets and add uapi/ header directories") replaced $(LINUXINCLUDE) with $(USERINCLUDE) which doesn't contain the necessary include paths. This has the undesirable effect of breaking the EFI boot stub because the #ifdef CONFIG_EFI_STUB code in arch/x86/boot/tools/build.c is never compiled. It should also be noted that because $(USERINCLUDE) isn't exported by the top-level Makefile it's actually empty in arch/x86/boot/Makefile. Cc: H.

git://git.infradead.org/users/dhowells/linux-headers Pull UAPI disintegration for include/linux/{,byteorder/}*.h from David Howells: "The patches contained herein do the following: (1) Remove kernel-only stuff in linux/ppp-comp.h from the UAPI. I checked this with Paul Mackerras before I created the patch and he suggested some extra bits to unexport. (2) Remove linux/blk_types.h entirely from the UAPI as none of it is userspace applicable, and remove from the UAPI that part of linux/fs.h that was the reason for linux/blk_types.h being exported in the first place. I discussed this with Jens Axboe before creating the patch. (3) The big patch of the series to disintegrate include/linux/*.h as a unit. This could be split up, though there would be collisions in moving stuff between the two Kbuild files when the parts are merged as that file is sorted alphabetically rather than being grouped by subsystem. Of this set of headers, 17 files have changed in the UAPI exported region since the 4th and only 8 since the 9th so there isn't much change in this area - as one might expect. It should be pretty obvious and straightforward if it does come to fixing up: stuff in __KERNEL__ guards stays where it is and stuff outside moves to the same file in the include/uapi/linux/ directory. If a new file appears then things get a bit more complicated as the "headers +=" line has to move to include/uapi/linux/Kbuild.
