68063cd8b6 lib/blob: force md update during decouple parent
Fixes #1933

When decoupling parent the updated parent_id was
not persisted to the blob if it was a snapshot.
Due to having md_ro set to true, blob_set_xattr()
failed.

Later on the incorrect parent_id could cause troubles
like in the github issue, when deleting that snapshot.

This patch adds return code check for blob_set_xattr
and forces md_ro to false during blob md sync.

Since some of code paths are shared between decouple,
inflate and clone operations, the final callback for them
is doing revert of the original md_ro.

d8843dccc5 nvmf/reservation: register new registrant when IEKEY is enabled
The specification says:
"A host may replace its reservation key without regard to its registration
status or current reservation key value by setting the Ignore Existing Key
(IEKEY) bit to '1' in the Reservation Register command."

So for this case we treat it as a new registrant, also add UT to cover
the added cases.

a066f0c3fb nvme: Fix the bug that assumed ANA group descriptor is 8-bytes aligned
This fix is as same as for NVMe bdev module.

If a ANA log page has two or more ANA group descriptors, the second
or later of ANA group descriptors will not be 8-bytes aligned.
Then runtime error would occur as follows:

runtime error: member access within misaligned address 0x612000000074
for type 'const struct spdk_nvme_ana_group_descriptor', which requires
8 byte alignment

nvmf_get_ana_log_page() in lib/nvmf/ctrlr.c creates a ANA log page
data and processes 8 bytes alignment correctly because we got the
same runtime error before. However, lib/nvme had been missed at that
time.

7ec6d1d559 bdev/nvme: Read ANA log page itself when nvme_ctrlr is created
If ctrlr supports ANA log page, nvme_ctrlr allocates a buffer for ANA
log page and read ANA log page itself, and then each nvme_ns sets its
ANA state by parsing ANA log page.

Most code was brought from NVMe driver because NVMe driver already
supports ANA log page management. However it had a bug that assumed
each descriptor is 8-bytes aligned. Fix the bug together in this
patch. Besides, the implementation in NVMe driver was synchronous.
NVMe bdev module reads ANA log page asynchronously instead.

The next patch will support ANA log page update by AER handler.

2ed914f8ea idxd: Add the kernel idxd support
This patch is used to add the kernel idxd support.

Without this patch, we can use userspace idxd driver
under accel_engine library (module/accel/idxd/accel_engine).
With this patch, we can also kernel idxd driver under the
accel_engine library.

Our approach is implementing a wrapper library to use IDXD
device by leveraging the kernel DSA driver in SPDK idxd library
(lib/idxd).

Then users can leverage the RPC later to configure how to
use the DSA device by user space driver or kernel driver.

In this patch, our approach is to use the idxd-config library
to export the WQs (Working Queues) exported by the kernel.

798ad0fb16 test/scheduler: reorder checks in interrupt test for debugging
Related to #1950
In the issue, CPU idle time measured from /proc/stats make it
seem like no reactor goes idle.

If true, then it would help for debugging to check stats from reactors.
Their busy/idle time and number of threads on them.

This patch reorders the checks in interrupt test,
to first show reactor stats, then confirm with idle time from
/proc/stats.

97c5373fc7 test/scheduler: make activity of a thread % of time period
So far the test application was mostly used for cases with
single active thread on a core.
Setting activity as percentage of all poller operations worked
fine for those cases.

This patch changes the thread activity to mean percentage of
a set time period.
Which equals to the maximum load a thread will see when being
alone on the core.

Right now g_core_time_period is set to 100ms, and is the
maximum execution time for all threads on a core when
thread activity is set to 100%.
g_timeslice is set to 100us and is the execution time of
single thread poll.

Consider following scenario:

Before the patch
Thread1	Activity 70%	Busy 70		Idle 30	Load 70%
Thread2	Activity 60%	Busy 60		Idle 40	Load 60%
Core			Busy 130	Idle 70	Load 65%

After the patch
Thread1	Activity 70%	Busy 100	Idle 0	Load 100%
Thread2	Activity 60%	Busy 100	Idle 0	Load 100%
Core			Busy 200	Idle 0	Load 100%

Additionally increased period of sleeping from 1us to 100us,
to offset the time needed for additional operations
during thread poll.

11c9b3960b scheduler_dynamic: move thread to least busy core
In cases when all cores are already doing too much work
to fit a thread, active threads should still be balanced
over all cores.

When current core is overloaded, place the thread
on another that is less busy.

The core limit is set to 95% to catch only ones that are
fully busy.
Decreasing that value would make spreading out the threads
move aggressive.

Changed thread load in one of the unit tests to reflect the
95% limit.

3959e397d4 nvme: Add new detach to a detach context while it is being polled
This update will allow us to use spdk_nvme_detach_async() and
spdk_nvme_detach_poll_async() easier to aggregate multiple detachments.

Previously, we could do:
    spdk_nvme_detach_async()
    spdk_nvme_detach_async()
    spdk_nvme_detach_async()
and then started doing spdk_nvme_detach_poll_async().

Hence aggregating multiple detachments is already supported.

After this patch, the following sequence is possible:
    spdk_nvme_detach_async() = 0
    spdk_nvme_detach_async() = 0
    spdk_nvme_detach_async() = 0
    spdk_nvme_detach_poll_async() = -EAGAIN
    spdk_nvme_detach_async() = 0
    spdk_nvme_detach_async() = 0
    spdk_nvme_detach_poll_async() = -EAGAIN
    spdk_nvme_detach_poll_async() = -EAGAIN
    spdk_nvme_detach_poll_async() = -EAGAIN
    spdk_nvme_detach_poll_async() = 0

The actual changes is to remove the variable polling_started from
struct spdk_nvme_detach_ctx because it is not necessary anymore.

Clarify this change via updating the header file and CHANGELOG.
Verify this change by unit test.

9d48662103 check_format: Ignore shellcheck's SC2128 and SC2178 directives
These are currently prone to false-positives especially in terms of
scoping. Consider the following:

foo() {
	local bar=(42)
	echo "${bar[*]}"
}

bar=43
foo
echo "$bar"

Some versions of shellcheck, including the latest, 0.7.2, complain
about $bar being reused as a plain string here. This is incorrect
since foo() holds its own copy of bar[@] hence the assignment which
takes place outside of it doesn't affect its content.

SC2178 can be mitigated be reversing the order of declaration:

bar=43
foo() { ... }
...

but the SC2128 still remains.

Currently, in our code majority of these warnings are coming from
false-positives due to initial source'ing which most of our test
scripts do (e.g. they fetch a function where local bar=() is used
and in the test itself $bar happens to be assigned a plain string.
This is still valid code).

To mitigate, disable these directives untill shellcheck is capable
of properly interpreting scoping when checking them.

63fd943282 check_format: Fixes for shellcheck's SC2269 directive
SC2269: This variable is assigned to itself, so the assignment does
        nothing.

Since the --id check doesn't change the value of $id, remove it
completely. This simplifies the process_shm() so the --id type is
considered to a be default and $id changed only in case --pid was
explicitly requested.
