* [PATCH] md: Split reshape handler in check_reshape and start_reshapeNeilBrown2006-03-27
| | | | | | | | | | check_reshape checks validity and does things that can be done instantly - like adding devices to raid1. start_reshape initiates a restriping process to convert the whole array.

* [PATCH] md: Only checkpoint expansion progress occasionallyNeilBrown2006-03-27

* [PATCH] md: Checkpoint and allow restart of raid5 reshapeNeilBrown2006-03-27
| | | | | | | | | | | | | | | | | | | We allow the superblock to record an 'old' and a 'new' geometry, and a position where any conversion is up to. The geometry allows for changing chunksize, layout and level as well as number of devices. When using verion-0.90 superblock, we convert the version to 0.91 while the conversion is happening so that an old kernel will refuse the assemble the array. For version-1, we use a feature bit for the same effect. When starting an array we check for an incomplete reshape and restart the reshape process if needed. If the reshape stopped at an awkward time (like when updating the first stripe) we refuse to assemble the array, and let user-space worry about it.

* [PATCH] md: Final stages of raid5 expand codeNeilBrown2006-03-27
| | | | | | | | | | | | | | | | This patch adds raid5_reshape and end_reshape which will start and finish the reshape processes. raid5_reshape is only enabled in CONFIG_MD_RAID5_RESHAPE is set, to discourage accidental use. Read the 'help' for the CONFIG_MD_RAID5_RESHAPE entry. and Make sure that you have backups, just in case.

* [PATCH] md: Core of raid5 resize processNeilBrown2006-03-27
| | | | | | | | | | | | | | | | | | | | | | This patch provides the core of the resize/expand process. sync_request notices if a 'reshape' is happening and acts accordingly. It allocated new stripe_heads for the next chunk-wide-stripe in the target geometry, marking them STRIPE_EXPANDING. Then it finds which stripe heads in the old geometry can provide data needed by these and marks them STRIPE_EXPAND_SOURCE. This causes stripe_handle to read all blocks on those stripes. Once all blocks on a STRIPE_EXPAND_SOURCE stripe_head are read, any that are needed are copied into the corresponding STRIPE_EXPANDING stripe_head. Once a STRIPE_EXPANDING stripe_head is full, it is marks STRIPE_EXPAND_READY and then is written out and released.

* [PATCH] md: Infrastructure to allow normal IO to continue while array is ↵NeilBrown2006-03-27
| | | | | | | | | | | | | | | | | | | | | expanding We need to allow that different stripes are of different effective sizes, and use the appropriate size. Also, when a stripe is being expanded, we must block any IO attempts until the stripe is stable again. Key elements in this change are: - each stripe_head gets a 'disk' field which is part of the key, thus there can sometimes be two stripe heads of the same area of the array, but covering different numbers of devices. One of these will be marked STRIPE_EXPANDING and so won't accept new requests. - conf->expand_progress tracks how the expansion is progressing and is used to determine whether the target part of the array has been expanded yet or not.

* [PATCH] md: Allow stripes to be expanded in preparation for expanding an arrayNeilBrown2006-03-27
| | | | | | | | | | | | | | | | | | | Before a RAID-5 can be expanded, we need to be able to expand the stripe-cache data structure. This requires allocating new stripes in a new kmem_cache. If this succeeds, we copy cache pages over and release the old stripes and kmem_cache. We then allocate new pages. If that fails, we leave the stripe cache at it's new size. It isn't worth the effort to shrink it back again. Unfortuanately this means we need two kmem_cache names as we, for a short period of time, we have two kmem_caches. So they are raid5/%s and raid5/%s-alt Signed-off-by: Neil Brown <neilb@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] md: Split disks array out of raid5 conf structure so it is easier to ↵NeilBrown2006-03-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | grow The remainder of this batch implements raid5 reshaping. Currently the only shape change that is supported is added a device, but it is envisioned that changing the chunksize and layout will also be supported, as well as changing the level (e.g. 1->5, 5->6). The reshape process naturally has to move all of the data in the array, and so should be used with caution. It is believed to work, and some testing does support this, but wider testing would be great for increasing my confidence. You will need a version of mdadm newer than 2.3.1 to make use of raid5 growth. This is because mdadm need to take a copy of a 'critical section' at the start of the array incase there is a crash at an awkward moment. On restart, mdadm will restore the critical section and allow reshape to continue. I hope to release a 2.4-pre by early next week - it still needs a little more polishing. This patch: Previously the array of disk information was included in the raid5 'conf' structure which was allocated to an appropriate size. This makes it awkward to change the size of that array. So we split it off into a separate kmalloced array which will require a little extra indexing, but is much easier to grow.

* [PATCH] drivers/md/dm-raid1.c: Fix inconsistent mirroring after interrupted ↵Jun'ichi Nomura2006-03-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | recovery dm-mirror has potential data corruption problem: while on-disk log shows that all disk contents are in-sync, actual contents of the disks are not synchronized. This problem occurs if initial recovery (synching) is interrupted and resumed. Attached patch fixes this problem. Background: rh_dec() changes the region state from RH_NOSYNC (out-of-sync) to RH_CLEAN (in-sync), which results in the corresponding bit of clean_bits being set. This is harmful if on-disk log is used and the map is removed/suspended before the initial sync is completed. The clean_bits is written down to the on-disk log at the map removal, and, upon resume, it's read and copied to sync_bits. Since the recovery process refers to the sync_bits to find a region to be recovered, the region whose state was changed from RH_NOSYNC to RH_CLEAN is no longer recovered. If you haven't applied dm-raid1-read-balancing.patch proposed in dm-devel sometimes ago, the contents of the mirrored disk just corrupt silently. If you have, balanced read may get bogus data from out-of-sync disks. The patch keeps RH_NOSYNC state unchanged. It will be changed to RH_RECOVERING when recovery starts and get reclaimed when the recovery completes. So it doesn't leak the region hash entry. Description: Keep RH_NOSYNC state unchanged when I/O on the region completes. rh_dec() changes the region state from RH_NOSYNC (out-of-sync) to RH_CLEAN (in-sync), which results in the corresponding bit of clean_bits being set. This is harmful if on-disk log is used and the map is removed/suspended before the initial sync is completed.

The RH_NOSYNC region will be changed to RH_RECOVERING when recovery starts on the region and get reclaimed when the recovery completes. So it doesn't leak the region hash entry. Alasdair said: I've analysed the relevant part of the state machine and I believe that the patch is correct. (Further work on this code is still needed - this patch has the side-effect of holding onto memory unnecessarily for long periods of time under certain workloads - but better that than corrupting data.)

| | | | | | | | | | | | | | | | | When a snapshot becomes invalid, s->valid is set to 0. In this state, a snapshot can no longer be accessed.

At the same time, some unnecessary levels of indentation are removed and snapshot invalidation is moved into a single function that always generates a device-mapper event.

* [PATCH] device-mapper snapshot: replace sibling listAlasdair G Kergon2006-03-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The siblings "list" is used unsafely at the moment. Firstly, only the element on the list being changed gets locked (via the snapshot lock), not the next and previous elements which have pointers that are also being changed. Secondly, if you have two or more snapshots and write to the same chunk a second time before every snapshot has finished making its private copy of the data, if you're unlucky, _origin_write() could attempt its list_merge() and dereference a 'last' pointer to a pending_exception structure that has just been freed. Analysis reveals that the list is actually only there for reference counting. If 5 pending_exceptions are needed in origin_write, then the 5 are joined together into a 5-element list - without a separate list head because there's nowhere suitable to store it. As the pending_exceptions complete, they are removed from the list one-by-one and any contents of origin_bios get moved across to one of the remaining pending_exceptions on the list. Whichever one is last is detected because list_empty() is then true and the origin_bios get submitted. The fix proposed here uses an alternative reference counting mechanism by choosing one of the pending_exceptions as primary and maintaining an atomic counter there.

* [PATCH] device-mapper snapshot: fix origin_write pending_exception submissionAlasdair G Kergon2006-03-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Say you have several snapshots of the same origin and then you issue a write to some place in the origin for the first time. Before the device-mapper snapshot target lets the write go through to the underlying device, it needs to make a copy of the data that is about to be overwritten. Each snapshot is independent, so it makes one copy for each snapshot. __origin_write() loops through each snapshot and checks to see whether a copy is needed for that snapshot. (A copy is only needed the first time that data changes.) If a copy is needed, the code allocates a 'pending_exception' structure holding the details. It links these together for all the snapshots, then works its way through this list and submits the copying requests to the kcopyd thread by calling start_copy(). When each request is completed, the original pending_exception structure gets freed in pending_complete(). If you're very unlucky, this structure can get freed *before* the submission process has finished walking the list. This patch: 1) Creates a new temporary list pe_queue to hold the pending exception structures; 2) Does all the bookkeeping up-front, then walks through the new list safely and calls start_copy() for each pending_exception that needed it; 3) Avoids attempting to add pe->siblings to the list if it's already connected.

* [PATCH] framebuffer: cmap-setting return valuesAlan Curry2006-03-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | A set of 3 small bugfixes, all of which are related to bogus return values of fb colormap-setting functions. First, fb_alloc_cmap returns -1 if memory allocation fails. This is a hard condition to reproduce since you'd have to be really low on memory, but from studying the contexts in which it is called, I think this function should be returning a negative errno, and the -1 will be seen as an EPERM. Switching it to -ENOMEM makes sense. Second, the store_cmap function which is called for writes to /sys/class/graphics/fb0/color_map returns 0 for success, but it should be returning the count of bytes written since its return value ends up in userspace as the result of the write() syscall. Third, radeonfb returns 1 instead of a negative errno when FBIOPUTCMAP is called with an oversized colormap. This is seen in userspace as a return value of 1 from the ioctl() syscall with errno left unchanged. A more useful return value would be -EINVAL.

| | | | | | | | | | | | | | | A framebuffer driver for the display controller in AMD Geode GX processors (Geode GX533, Geode GX500 etc.). Tested at 640x480, 800x600, 1024x768 and 1280x1024 at 8, 16, and 24 bpp with both CRT and TFT. No accelerated features currently implemented and compression remains disabled. This driver requires that the BIOS (or the SoftVG/Firmbase code in the BIOS) has created an appropriate virtual PCI header.

* [PATCH] nvidiafb: add suspend and resume hooksAntonino A. Daplas2006-03-27
| | | | | | | | | | | | | | | | | Add suspend and resume hooks to make software suspend more reliable. Resuming from standby should generally work. Resuming from mem and from disk requires that the GPU is disabled. Adding these to the suspend script... fbset -accel false -a /* suspend here */ fbset -accel true -a ... should generally work. In addition, resuming from mem requires that the video card has to be POSTed by the BIOS or some other utility.
