kmem_alloc() with KM_SLEEP
kmem_zalloc() with KM_SLEEP
percpu_alloc()
pserialize_create()
psref_class_create()
all of these paths include an assertion that the allocation has not failed,
so callers should not assert that again.

fixes the i386 ALL build with clang which complained about the
format string not being a string literal, and lets us get rid of
rf_panicbuf.
note: kern_assert is not KASSERT. it should panic as long as the
string is not NULL.
No functional change intended.

Thanks!

when the code was switched over to dk_ioctl() - countrary to disk_ioctl(),
dk_ioctl() returns ENOTTY for ioctls it doesn't support, so must be called
as last resort, not first
bug was introduced in rev 1.83 (2015-05-02) for ld(4), and 1.335 (2016-01-03)
for raid(4)

valid to call biowait() after biodone. (thanks chuq)

Pseudo devices like vnd and cgd can be opened but may still
need some configuration. Ignore these quietly.

- offset dump by RF_PROTECTED_SECTORS (thanks oster@ for noticing)
- call component dump function with byte count instead of block count
- return -1 instead of errno values in dk_size for error conditions.
There are still issues with dumping.
- the raid device must be open, neither reading the disklabel
nor flushing the component labels in rfmarkdirty is possible
when dumping.
- dumping to a wedge component fails because the wedge driver only
allows dumping to swap partitions, not raid partitions.

instead just mark the device for shutdown and detach on last close.
Also don't manually print the detached message but leave this to
config_detach(). This avoids a duplicate message when shutting down.

the situation (as a WARNING) and continue. Don't return the error code
to the caller. Failure to register should not really happen - if it
does, all we really lose is auto-configuration of raid-sets.

code to permit detaching (and possible module unloading). Also,
convert tsleep()/wakeup() locking to use cv_wait_sig()/cv_broadcast().
Tested in non-modular, modular-builtin, and modular-loaded-at-runtime
environments.

This covers (I think) all the MI headers outside of external/ (and dist/).

altq Drop Type
disklabel Disk Type
file Descriptor Type
(not to mention constants that contain the string DTYPE).
Let's make them two, by changing the disklabel one to be DisK TYPE since the
other disklabel constants seem to do that. Not many userland programs use
these constants (and the ones that they do are mostly in ifdefs). They will
be fixed shortly.
|
|
we can merge the "easy" disklabel ioctls to it. Ultimately all this will
go do dk_ioctl once all the drivers have been converted.
|
|
|
|
to the disk subsystem.
Make disk_set_info also set blocksize shift values.
Remove every call to disk_blocksize.
Keep disk_blocksize for ABI compatibility, make it also set dg_secsize.

reconstruct-to-spare is underway but not yet complete.
The issue was that a component was being marked as a used_spare when
the rebuild started, not when the rebuild was actually finished.
Marking it as a used_spare meant that the component label on the spare
was being updated such that after a reboot the component would be
considered up-to-date, regardless of whether the rebuild actually
completed!
This fix includes:
1) Add an additional state "rf_ds_rebuilding_spare" which is used
to denote that a spare is currently being rebuilt from the live
components.
2) Update the comments on the disk states, which were out-of-sync
with reality.
3) When rebuilding to a spare component, that spare now enters the
state rf_ds_rebuilding_spare instead of the state rf_ds_used_spare.
4) When the rebuild is actually complete then the spare component
enters the rf_ds_used_spare state. rf_ds_used_spare is now used
exclusively for the case where the rebuilding to the spare has
completed successfully.
XXX: Someday we need to teach raidctl(8) about this new state, and
take out the backwards compatibility code in rf_netbsdkintf.c (see
RAIDFRAME_GET_INFO in raidioctl()). For today, this fix needs to be
generic enough that it can get backported without major grief.
XXX: Needs pullup to netbsd-5*, netbsd-6*, and netbsd-7
Fixes PR#49244.

All have been set to "nodiscard"; some should get a real implementation.
