Pull in fixes from upstream v72 and v73

Browse Source 
We could not rebase to v73 because there was an incompatible config
file change (the file both changed in format and moved location).
Unfortunately, that configuration change also added externally facing
APIs, and with them, new versioned symbols.  As a result, I couldn't
pull in all fixes because it would result in an incompatible list of
symbols in a given ABI version.  Long term, upstream is aware of the
config file problem, and is looking to address it by supporting both
old and new formats and locations.

This update addresses the following reported bugs:
- Fix enable-namespace all reporting errors incorrectly
- Add support for inject-smart on papr scm

ndctl/namespace: Suppress -ENXIO when processing all namespaces.

commit 07011a334fd1e4b641cdbfaf5de7500f7bdc941d

ndctl/namespace: Suppress -ENXIO when processing all namespaces.
When processing all namespaces and no namespaces exist user gets the
default -ENXIO. Set default rc to 0 when processing all namespaces.
This avoids confusing error message printed in addition to the message
saying 0 namespaces were affected.
Before:
# ndctl check-namespace all
namespace0.0: namespace_check: namespace0.0: check aborted, namespace online
error checking namespaces: Device or resource busy
checked 0 namespaces
# ndctl disable-namespace all
disabled 1 namespace
# ndctl check-namespace all
namespace0.0: namespace_check: Unable to recover any BTT info blocks
error checking namespaces: No such device or address
checked 0 namespaces
# ndctl destroy-namespace all
destroyed 1 namespace
# ndctl check-namespace all
error checking namespaces: No such device or address
checked 0 namespaces
# ndctl destroy-namespace all
error destroying namespaces: No such device or address
destroyed 0 namespaces
After:
# ndctl check-namespace all
namespace0.0: namespace_check: namespace0.0: check aborted, namespace online
error checking namespaces: Device or resource busy
checked 0 namespaces
# ndctl disable-namespace namespace0.0
disabled 1 namespace
# ndctl check-namespace all
namespace0.0: namespace_check: Unable to recover any BTT info blocks
error checking namespaces: No such device or address
checked 0 namespaces
# ndctl destroy-namespace all
destroyed 1 namespace
# ndctl check-namespace all
checked 0 namespaces
# ndctl destroy-namespace all
destroyed 0 namespaces
# ndctl destroy-namespace all
destroyed 0 namespaces
Note: this does change the return value from -ENXIO to 0 in the cases
when no namespaces exist and processing all namespaces was requested.

ndctl/scrub: Reread scrub-engine status at start
Given that the kernel has exponential backoff to cover the lack of
interrupts for scrub completion status there is a reasonable likelihood
that 'ndctl start-scrub' is issued while the hardware/platform scrub-state
is idle, but the kernel engine poll timer has not fired.
Trigger at least one poll cycle for the kernel to re-read the scrub-state
before reporting that ARS is busy.

ndctl/namespace: Skip seed namespaces when processing all namespaces.
The seed namespaces are exposed by the kernel but most operations are
not valid on seed namespaces.
When processing all namespaces the user gets confusing errors from ndctl
trying to process seed namespaces. The kernel does not provide any way
to tell that a namspace is seed namespace but skipping namespaces with
zero size and UUID is a good heuristic.
The user can still specify the namespace by name directly in case
processing it is desirable.

libndctl/papr: Add limited support for inject-smart
BZ:
Brew:
commit 9ef460eb7fd1b1f286955b18db8c18cd1a640e77
Author: Vaibhav Jain <vaibhav@linux.ibm.com>

libndctl/papr: Add limited support for inject-smart
Implements support for ndctl inject-smart command by providing an
implementation of 'smart_inject*' dimm-ops callbacks. Presently only
support for injecting unsafe-shutdown and fatal-health states is
available.
The patch also introduce various PAPR PDSM structures that are used to
communicate the inject-smart errors to the papr_scm kernel
module. This is done via SMART_INJECT PDSM which sends a payload of
type 'struct nd_papr_pdsm_smart_inject'.
With the patch following output from ndctl inject-smart command is
expected for PAPR NVDIMMs:
$ sudo ndctl inject-smart -fU nmem0
[
{
"dev":"nmem0",
"flag_failed_flush":true,
"flag_smart_event":true,
"health":{
"health_state":"fatal",
"shutdown_state":"dirty",
"shutdown_count":0
}
}
]
$ sudo ndctl inject-smart -N nmem0
[
{
"dev":"nmem0",
"health":{
"health_state":"ok",
"shutdown_state":"clean",
"shutdown_count":0
}
}
]
The patch depends on the kernel PAPR PDSM implementation for
PDSM_SMART_INJECT posted at [1].

libndctl/papr: Add support for reporting shutdown-count
Add support for reporting dirty-shutdown-count (DSC) for PAPR based
NVDIMMs. The sysfs attribute exposing this value is located at
nmemX/papr/dirty_shutdown.
This counter is also returned in payload for PAPR_PDSM_HEALTH as newly
introduced member 'dimm_dsc' in 'struct nd_papr_pdsm_health'. Presence
of 'DSC' is indicated by the PDSM_DIMM_DSC_VALID extension flag.
The patch implements 'ndctl_dimm_ops.smart_get_shutdown_count'
callback in implemented as papr_smart_get_shutdown_count().
Kernel side changes to support reporting DSC have been merged to linux kernel
via patch proposed at [1]. With updated kernel 'ndctl list -DH' reports
following output on PPC64:
$ sudo ndctl list -DH
[
{
"dev":"nmem0",
"health":{
"health_state":"ok",
"life_used_percentage":50,
"shutdown_state":"clean",
"shutdown_count":10
}

libndctl: Unify adding dimms for papr and nfit families
In preparation for enabling tests on non-nfit devices, unify both, already very
similar, functions into one. This will help in adding all attributes needed for
the unit tests. Since the function doesn't fail if some of the dimm attributes
are missing, this will work fine on PAPR platforms though only part of the DIMM
attributes are provided (This doesn't mean that all of the DIMM attributes can
be missing).

libndctl/papr: Fix probe for papr-scm compatible nvdimms
With recent changes introduced for unification of PAPR and NFIT
families the probe for papr-scm nvdimms is broken since they don't
expose 'handle' or 'phys_id' sysfs attributes. These attributes are
only exposed by NFIT and 'nvdimm_test' nvdimms. Since 'unable to read'
these sysfs attributes is a non-recoverable error hence this prevents
probing of 'PAPR-SCM' nvdimms and ndctl reports following error:
$ sudo NDCTL_LOG=debug ndctl list -DH
libndctl: ndctl_new: ctx 0x10015342c70 created
libndctl: add_dimm: nmem1: probe failed: Operation not permitted
libndctl: __sysfs_device_parse: nmem1: add_dev() failed
libndctl: add_dimm: nmem0: probe failed: Operation not permitted
libndctl: __sysfs_device_parse: nmem0: add_dev() failed
Fixing this bug is complicated by the fact these attributes are needed
for by the 'nvdimm_test' nvdimms which also uses the
NVDIMM_FAMILY_PAPR. Adding a two way comparison for these two
attributes in populate_dimm_attributes() to distinguish between
'nvdimm_test' and papr-scm nvdimms will be clunky and make future
updates to populate_dimm_attributes() error prone.
So, this patch proposes to fix the issue by re-introducing
add_papr_dimm() to probe both papr-scm and 'nvdimm_test' nvdimms. The
'compatible' sysfs attribute associated with the PAPR device is used
to distinguish between the two nvdimm types and in case an
'nvdimm_test' device is detected then forward its probe to
populate_dimm_attributes().

libndctl, intel: Indicate supported smart-inject types

commit edcd9b7e10b3b33a9660e412a2db1beab30936d3

libndctl, intel: Indicate supported smart-inject types
Presently the inject-smart code assumes support for injecting all
smart-errors namely media-temperature, controller-temperature,
spares-remaining, fatal-health and unsafe-shutdown. This assumption
may break in case of other non-Intel NVDIMM types namely PAPR NVDIMMs
which presently only have support for injecting unsafe-shutdown and
fatal health events.
Trying to inject-smart errors on PAPR NVDIMMs causes problems as
smart_inject() prematurely exits when trying to inject
media-temperature smart-error errors out.
To fix this issue the patch proposes extending the definition of
dimm_op 'smart_inject_supported' to return bitmap of flags indicating
the type of smart-error injections supported by an NVDIMM. These types
are indicated by the newly introduced defines ND_SMART_INJECT_* . A
dimm-ops provide can return an bitmap composed of these flags back
from its implementation of 'smart_inject_supported' to indicate to
dimm_inject_smart() which type of smart-error injection it
supports. In case of an error the dimm-op is still expected to return
a negative error code back to the caller.
The patch updates intel_dimm_smart_inject_supported() to return a
bitmap composed of all ND_SMART_INJECT_* flags to indicate support for
all smart-error types.
Finally the patch also updates smart_inject() to test for specific
ND_START_INJECT_* flags before sending a smart-inject command via
dimm-provider.

papr: Add support to parse save_fail flag for dimm
This will help in getting the dimm fail tests to run on papr family too.
Also add nvdimm_test compatibility string for recognizing the test module.

zero_info_block: skip seed devices
BZ:
Brew:
commit fb13dfb8d84c4f0a749665c8f07179450b199f3e
Author: Jeff Moyer <jmoyer@redhat.com>
Date: Tue Feb 9 16:51:53 2021 -0500
zero_info_block: skip seed devices
Currently, ndctl destroy-namespace -f all will output errors of the
form:
Error: destroy namespace: namespace0.0 failed to enable for zeroing, continuing
for any zero-sized namespace. That particular namespace looks like this:
{
"dev":"namespace0.0",
"mode":"raw",
"size":0,
"uuid":"00000000-0000-0000-0000-000000000000",
"sector_size":512,
"state":"disabled"
}
This patch skips over namespaces with size=0 when zeroing out info
blocks.

Author: Santosh Sivaraj <santosh@fossix.org>

Use page size as alignment value
The alignment sizes passed to ndctl in the tests are all hardcoded to 4k,
the default page size on x86. Change those to the default page size on that
architecture (sysconf/getconf). No functional changes otherwise.
