There was a problem hiding this comment.
I would update commit message to something like
"perf: Log error if mandatory parameters are missing"
Also Mellanos SPDK fork is very old, so you'll need to get SPDK from https://github.com/spdk/spdk.
And we usually use this fork to push "draft" changes for internal review to separate branch without creating pull requests. After this internal review you'll need to learn about SPDK contribution process https://spdk.io/development (I suppose Sasha has already told about it)
If "-o" (block size), "-q" (query size), "-t" (time in seconds), "-w" (io pattern) is absent, per doesn't report any message. Signed-off-by: Ivan Betsis <[email protected]> Signed-off-by: Alla Kiseleva <[email protected]>

Not all JSON methods require 'params' field to be supplied.
Verification of the JSON is done on server side in
parse_single_request().
We should not attempt to process garbage values on correct
JSON config file during app start.
Segfault can be observed if following valid JSON config is supplied:
{
"method": "framework_wait_init"
}
Resulting in:
json_config.c:388:13: runtime error: applying non-zero offset 18446744073709551600 to null pointer

As per typedef in nvme.h the spdk_nvme_cpl argument should be a
pointer to a const struct.
This fixes runtimer error under clang >= 17.x which now makes the
-fsanitize=function available for C and which on our end is being
enabled via -fsanitize=undefined under UBSAN.
