7dc38f83f7 spdk_top: reduce number of global thread data structures
Deletes g_thread_history and g_thread_info to use g_threads_stats
across the whole application to simplify spdk_top code.
Now instead of separate struct, fields last_busy and last_idle are
being used.

get_data() function now uses local structure to get RPC data instead
of filling global one. This has been changed so that g_threads_stats
keeps its last_busy and last_idle fields unchanged.
free_rpc_threads_stats has been moved down so that in future patches,
when multithreading is implemented, there is no need to lock
g_threads_stats during RPC call.

Changes places of allocation/deallocation of g_threads_stats, since
we want to save last_idle and last_busy fields instead of zeroing them
out each application loop.

Changes show_thread() function to use local copy of threads array
instead of pointers to global struct. This is for the convenience
in the future patches implementing multithreading to avoid the need
to lock the global struct for details display.

464ddc03b6 spdk_top: change where get_data() and free_data() are called
Move part of code with get_data(), refresh_tab() and free_data()
inside show_stats() upwards to make sure data structures are
up to date for pop-up details windows.

Delete get_data(), free_data() calls from show_thread(), show_poller()
and show_core functions.

Add data freeing right before rpc calls inside get_data() to let
pop-up details windows to use updated data before freeing it.

10b7805b0f scripts/rpc: Make sure address argument is properly interpreted
In case the addr argument was not an existing unix socket file the rpc
client would consider it to be an actual ip address. As a result
connect() would be called with improper set of arguments. This could
cause the rpc.py to block for undesired amount of time until connect()
finally decided to return (seen on some fedora33 builds).

This was affecting sh wrapper functions like waitforlisten() which
use rpc.py to determine if given app is ready to be talk to blocking
execution of the tests for way too long then intendent.

To avoid such a scenario determine the format of the address and use
routines proper for given address family.

0fdf94cf77 lib/blob: force execution of queued persists
When performing snapshot creation the I/O is frozen
during the process. The blob persists for extent page
allocation is delayed until snapshot creation is finished.

This results in multiple blob persists executing one after
the other, with only intent of writing out updated extent table
pointing to new extent pages.
Since blob->state is marked DIRTY before issuing each persist,
but a single persist completion marks state CLEAR.

Blob serialize correctly expects each persist to contain
dirtied metadata, in order to avoid unnecessary md writes.
Since all other instances of marking blob DIRTY is explicit,
assert in blob serialize is left as is.

Instead when running the queued up blob persists, the blob
state is marked DIRTY.

Side effect is that it will write out same md in some cases.

Fixes #1909

4f8b83cf51 nvme: reset mapping_length correctly for contig SGL
spdk_vtophys() takes a mapping_length parameter, so
it can return the length for which the returned
virtual address is valid.

But spdk_vtophys() will only return the max
between the valid length and the input mapping_length
parameter.

So the nvme SGL building code for contiguous buffers
was broken, since it would only set the mapping_length
once, before the loop started.  Worst case, if a buffer
started just before (maybe 256 bytes) before a huge page
boundary, each time through the loop we would create
a new SGL for only 256 bytes at a time, very quickly
running out of SGL entries for a large buffer.

Fixes #1852.

35d003dfed nvme: remove IDENTIFY_CNS quirk from normal QEMU SSDs
The IDENTIFY_CNS quirk was applied as part of QEMU
OCSSD handling in commit 6442451b.  But it was applied
not only to the OCSSD dev ID, but also the dev ID
for non-OCSSD NVMe controllers.

Starting with QEMU 5.2, QEMU will allocate a default
256 namespaces, but only some are active (associated
with the backing disks specified by the user).  QEMU
supports IDENTIFY_CNS, but since this quirk was set,
we wouldn't send a real IDENTIFY_CNS and instead
would just populate a fake list where all namespaces
were considered active.  This causes breakage in
a few places - mainly where we iterate through
the active namespaces, and then are surprised that
calling spdk_nvme_ns_is_active() returns false.

It was also breaking bdev_nvme_attach_controller RPC,
since by default we can only support returning 128
names, but since all of the namespaces were deemed
active, it was trying to return 256.

Fixes #1916.

bdev_nvme, bdev_ocssd, and vbdev_zone_block.

For all three modules, the number of zones can be calculated using:
block_count / zone_size.

To avoid this calculation being performed everywhere, create a helper
function in bdev_zone.h, together with the other zone APIs, such that
a user can easily get the number of zones.

d69349af6b nvme/fio_plugin: fix zone_append option with multiple files per thread
Each fio thread can have multiple files that it writes to.
Which is why the per thread spdk_fio_setup() fio callback does
for_each_file() {...}.

One of these files can be e.g. a zoned namespace with append support,
another file could be a zoned namespace on another controller without
append support, and a third file could be a conventional namespace
(which never supports the zone append command).

Right now, we will return a fatal error if a thread has e.g. a zoned
namespace (with append support) together with a conventional namespace.

Instead of returning a fatal error, enable zone append only on the
namespaces that support zone append, and allow namespaces that do
not support zone append to continue as usual (using regular writes).

09dd961b35 nvme/fio_plugin: fix report_zones
Commit f69367c788 ("fio_nvme: defer qpair allocation to file_open
callback") moved the qpair allocation from spdk_fio_setup() to
spdk_fio_open(). This broke spdk_fio_report_zones(), which needs a
qpair in order to get the initial state of the zones.

setup_files() in FIO calls td->io_ops->setup() (spdk_fio_setup()),
followed by zbd_init_files(), which calls zbd_init_zone_info(),
which calls zbd_create_zone_info(), which calls parse_zone_info(),
which calls zbd_report_zones(), which calls td->io_ops->report_zones()
(spdk_fio_report_zones()).

i.e. spdk_fio_report_zones() will always be called directly after
spdk_fio_setup(). .report_zones() is even called before the per
thread ioengine .init() callback.

Therefore, spdk_fio_report_zones() is called before the ioengine
.open_file() callback.

This is done in order to ensure that all threads will share the same
zbd_info struct, which contains the per zone locks.

Since SPDK nvme ioengine no longer initializes the qpairs in .setup(),
create a temporary qpair in .report_zones().

While at it, move the initial zone reset from spdk_fio_setup() to
attach_cb(), as this is where all the other fio options are verified.
By placing it in attach_cb(), after the duplicated file check, we
avoid the need to loop through the whole fio_thread->fio_qpair list.

Since SPDK nvme ioengine no longer initializes the qpairs in .setup(),
create a temporary qpair, if the --initial_zone_reset option was used.

365db9ee48 sock/posix: Deal with hung I/O with MSG_ZEROCOPY and interrupt
suppression

When all of the following conditions are met:
- non-blocking socket
- zero copy is enabled
- interrupts are suppressed (i.e. busy polling)
- NIC tx queue is full at the time sendmsg() is called
- epoll_wait sees there is already an EPOLLIN event
then we can get into a situation where data we've sent is queued
up in the kernel network stack, but interrupts have been suppressed
because other traffic is flowing. This makes the kernel miss the
signal to flush the software tx queue. If there wasn't also already
a pending EPOLLIN event, then epoll_wait would have been sufficient
to kick the system out of this state. But when all of this aligns,
it hangs.

We deal with this by detecting the scenario and calling poll(), which
will force the kernel to issue the pending transmits.

For pollers that don't natively support interrupts, using

An interrupt falicity for busy wait will

Internally, an eventfd is created to each busy wait
poller. Write the eventfd when set interrupt mode,
and only read the eventfd when set back to poll mode,
then the busy wait poller will be called repeatly
in interrupt mode.

6c75f0a266 env_dpdk: save hotplug timeout timestamps separate from rte_devargs
DPDK recently clarified some semantics on the rte_devargs 'data'
and 'args' fields.  This actually breaks our use of the 'data'
field to store the 2 second timeout timestamp for delaying
attach to newly inserted devices.  Investigating this further,
it does not seem our use of the 'data' field was valid - it just
happened to work until now.

We could use the 'args' field now.  But knowing whether to use
'args' or 'data' would then be dependent on the DPDK version.
We cannot use RTE_VERSION_NUM to decide, because this is a
compile time decision, and it is possible in shared library
use cases that we could actually link and execute against a
different version of DPDK than we built against.

So instead we will create our own env_devargs structure that
will store these allowed_at timestamps. Currently it's just
a linked list (which is exactly how DPDK does it) - we could
make it more optimal with a hash table down the road, but this
code only executes when we are doing PCI enumeration so it is
not performance critical.

Fixes #1904.

ae10cf633c lib/blob: do not write extent pages during md sync for thin blobs
Before this patch blob persist wrote out all allocated extent pages.

Intended design was to write out extent pages in two cases:
1) Thin provisioned blobs to write out extent pages when necessary
during cluster allocation.
2) Thick provisioned blobs to write extent pages during blob persist
when the blob was resized

This patch implements 1) by inserting extent before issuing blob persist
in cluster allocation path.
See blob_persist_extent_page_cpl() and blob_insert_new_ep_cb().
Blob persist might have to rewrite the last extent page after blob resize.
See blob_persist_start().

Meanwhile 2) was incorrecly implemented since it always re-wrote all
extent pages starting from 0. This was addressed by limiting number
of extent pages written, only to ones that were resized.
Some considerations were needed:
a) blob resize happen on cluster granularity, it might be needed to re-write
last extent page if resize was not large enough to change number of extent pages
b) first extent page to write should be based on the num_extent_pages from
active or clean, depending on resize direction
See blob_persist_start().

a512214517 lib/blob: update extent pages during snapshot deletion
When both clone and snapshot had already extent pages
corresponding to the same region in cluster map,
the clone extent page was replaced with one from snapshot.

This was incorrect and would result in loss of clusters
from clones extent page. It did not occur in practice
because all extent pages were rewritten anyway during
md sync. Cluster map was correct so updated extent pages
were too.

Cluster map correctness is verified in UT _blob_inflate_rw(true),
at the very end when checking data consistency of inflated blob.

This patch writes out the updated extent page explicitly.
So it would be possible to skip wirting out extent pages
during md sync later in the series.

Note 1)
At this point in series the extent page is written here,
and in blob persists. The later will be removed later in
series.

Note 2)
Errors during updating extent pages are not accounted for,
but neither does syncing them in blob persist.
