|\ | | | | | | | | | | | | * 'for-linus' of git://neil.brown.name/md: md: Ensure an md array never has too many devices. md: Fix a bug in linear.c causing which_dev() to return the wrong device. md: Allow read error in a single drive raid1 to be passed up.
| * md: Ensure an md array never has too many devices.NeilBrown2009-02-061-10/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Each different metadata format supported by md supports a different maximum number of devices. We really should be enforcing this maximum in the kernel, but we aren't quite doing that properly. We currently only enforce it at the 'hot_add' point, which is an older interface which is not used by current userspace. We need to also enforce it at 'add_new_disk' time for active arrays and at 'do_md_run' time when starting a new array. So move the test from 'hot_add' into 'bind_rdev_to_array' which is called from both 'hot_add' and 'add_new_disk, and add a new test in 'analyse_sbs' which is called from 'do_md_run'. This bug (or missing feature) has been around "forever" and so the patch is suitable for any -stable that is currently maintained. Cc: stable@kernel.org Signed-off-by: NeilBrown <neilb@suse.de>
| * md: Fix a bug in linear.c causing which_dev() to return the wrong device.Andre Noll2009-02-061-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ab5bd5cbc8d4b868378d062eed3d4240930fbb86 introduced the following bug in linear software raid for large arrays on 32 bit machines: which_dev() computes the device holding a given sector by shifting down the sector number to a 32 bit range, dividing by the array spacing and looking up the resulting index in the hash table of the array. Because the computed index might be slightly too small, a loop at the end of which_dev() increases the index until the given sector actually falls into the range of the device associated with that index. The changes of the above mentioned commit caused this loop to check whether the _index_ rather than the sector number is small enough, effectively bypassing the loop and thus possibly returning the wrong device. As reported by Simon Kirby, this leads to errors such as linear_make_request: Sector 2340486136 out of bounds on dev sdi: 156301312 sectors, offset 2109870464 Fix this bug by introducing a local variable for the index so that the variable containing the passed sector is left unchanged.

| * md: Allow read error in a single drive raid1 to be passed up.NeilBrown2009-02-061-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | If a raid1 only has a single working device and gets a read error, we choose to simply return that error up to the filesystem (or whatever) rather than failing the whole array. However the codes doesn't quite do that. We attempt a readbalance which allocates the same drive, so we retry the read - indefinitely. Instead: If read_balance in the error case chooses the same drive that just failed, treat it as a failure and don't retry. Signed-off-by: NeilBrown <neilb@suse.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change spin_locks to irqsave to prevent dead-locks. Protect adding and deleting to/from dca_providers list. Drop the lock during dca_sysfs_add_req() and dca_sysfs_remove_req() calls as they might sleep (use GFP_KERNEL allocation).

It's usually okay to let EH handle speed down after transmission failures but some WD My Book drives completely shutdown after certain transmission failures and after it only power cycling can revive them. Combined with the fact that external drives often end up with cable assembly which is longer than usual and more likely to have intervening gender, this makes these drives very likely to shutdown under certain configurations virtually rendering them unusable. This patch implements HOARKGE_1_5_GBPS and applies it to WD My Book such that 1.5Gbps is forced once the device is identified.

This will be used to implement link SPD horkage which requires hardreset to adjust SPD without affecting other EH decisions. As it bypasses the forward progress guarantee provided by the tries count, the requester is responsible for ensuring forward progress.

This often leads to consecutive hotplug events without successful probing. This patch improves libata EH such that it remembers probing trials and if there have been more than two unsuccessful trials in the past 60 seconds, slows down link speed to 1.5Gbps. As link speed negotiation is the duty of the PHY layer proper, the goal of this fallback mechanism is to provide the last resort when everything else fails, which unfortunately happens not too infrequently, so no fancy 6->3->1.5 speeding down or highest successful transmission speed seen kind of logics (yet).
