Ensure that memzone count in eal mem config is incremented and
decremented whenever memzones are allocated and freed.

Currently, memzone autotest expects there to be no memzones
present by the time the test is run. Some hardware drivers
will allocate memzones for internal use during initialization,
resulting in tests failing due to unexpected memzones being
allocated before the test was run.
Fix this by making callback increment a counter instead. This
also doubles as a test for correct operation of memzone_walk().

Looks OK.
Following note is aside from the patch.
Might be beneficial (in some rare cases) to add bailout recovery with
goto's in test_memzone_basic()
Just in case one of the rte_memzone_reserve() we should not make return -1,
but instead a goto to below section where we call rte_memzone_free().
This way we would be able to free only the allocated memzones and prevent
leaking out those memzones to other tests.

Thanks, and yep, it's on my todo list :) didn't get around to it yet.

Hi Anatoly,
I think your fix is elegant, however you can't grantee it doesn't have dirty memzone remained after memzone autotest.
What if some existed initial memzone released during the test and some dirty memzone remained. The counter cannot illustrate this state.
My fix just care about the memzone used in memzone autotest. It is rough but it seems more reliable. 😊
Thanks,
Phil Yang

We could combine the approaches. That way, we both ensure that no
memzones were left in that should've been freed, and that total number
of memzones didn't change as well (i.e. we didn't allocate/free any
memzones we weren't supposed to allocate/free).
As i side note, i think making a #define with memzone prefix in your
patch will work better and will be less copypaste-error-prone in the
long run.
I will prepare a v2 combining both approaches. Is that OK with you?

decremented whenever memzones are allocated and freed.

To: dev; +Cc: radoslaw.biernacki, stable
Currently, memzone autotest expects there to be no memzones
present by the time the test is run. Some hardware drivers
will allocate memzones for internal use during initialization,
resulting in tests failing due to unexpected memzones being
allocated before the test was run.
Fix this by making sure all memzones allocated by this test
have a common prefix, and making callback increment a counter
on encountering memzones with this prefix. Also, separately
increment another counter that will count total number of
memzones left after test, and compares it to previously stored
number of memzones, to ensure that we didn't accidentally
allocated/freed any memzones we weren't supposed to. This
also doubles as a test for correct operation of memzone_walk().

Currently, memzone autotest expects there to be no memzones
present by the time the test is run. Some hardware drivers
will allocate memzones for internal use during initialization,
resulting in tests failing due to unexpected memzones being
allocated before the test was run.
Fix this by making sure all memzones allocated by this test
have a common prefix, and making callback increment a counter
on encountering memzones with this prefix. Also, separately
increment another counter that will count total number of
memzones left after test, and compares it to previously stored
number of memzones, to ensure that we didn't accidentally
allocated/freed any memzones we weren't supposed to. This
also doubles as a test for correct operation of memzone_walk().
Fixes: 71330483a193 ("test/memzone: fix memory leak")

Notes:
v3: suggested-by was supposed to be a signoff
v2: incorporated Phil Yang's patch to better ensure
no memzones were left behind by the test

Currently, memzone autotest expects there to be no memzones
present by the time the test is run. Some hardware drivers
will allocate memzones for internal use during initialization,
resulting in tests failing due to unexpected memzones being
allocated before the test was run.
Fix this by making sure all memzones allocated by this test
have a common prefix, and making callback increment a counter
on encountering memzones with this prefix. Also, separately
increment another counter that will count total number of
memzones left after test, and compares it to previously stored
number of memzones, to ensure that we didn't accidentally
allocated/freed any memzones we weren't supposed to. This
also doubles as a test for correct operation of memzone_walk().
Fixes: 71330483a193 ("test/memzone: fix memory leak")

no memzones were left behind by the test
