Bug description:
---Problem Description---
I have had trouble collecting data via the zcryptstats
(https://github.com/ibm-s390-tools/s390-tools/blob/master/zconf/zcrypt/zcryptstats.c)
tool for our Hosting Appliance - VPC environment. Basically, the tool reports
data for only the last two domain IDs. Further, it hangs if I collect data for
a complete crypto card, and then I have to kill the ssh session to get back.
strace attached, ltrace not available and can't be installed due to no
Internet access.
===================
Addl. Information:
This seems to be a problem with the handling of partial responses of
the SCDMD CHSC command.
When many domains are available, then the output of all domains does
not fit into the output buffer of one CHSC call. Thus, the response
contains a partial-response-bit that indicates that there is more data
to be retrieved. This is done in a subsequent CHSC call, but there is
an error in zcryptstats with populating the request with the next
domain number to obtain data for. This results in the fact that it
retrieves the data for domains 1 to n over and over again, and always
gets the partial-response bit set. So this loops forever.
===================
The fix for this in now upstream:
https://github.com/ibm-s390-tools/s390-tools/commit/cf2311f1f1de17435b49ba8c8697be91705ba031
This need to be integrated in all Ubuntu distros, from 20.04 on. F/G/H
