---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 |
SRU Justification:
==================
[Impact]
* If multiple s390x crypto domains are available,
the output of all domains does no longer fit into the output buffer of one CHSC call.
* Thus, the response contains a partial-response-snippet that indicates that there is more data to be retrieved.
* The remaining data is then retrieved in a subsequent CHSC call,
but there is an error in zcryptstats in 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 snippet, hence this loops indefinitely.
[Test Case]
* An Ubuntu Server 20.04 system (or newer) is needed on z/VM or LPAR with two or more crypto domains accessible.
* Now call 'zcryptstats --all -V' and verify if the command completes successfully (within seconds) or hangs (loops).
[Where problems could occur]
* The patch fixes the code that passes the correct next-domain to the subsequent CHSC call of a partial response.
* In case done wrong even no data at all from any of the domains is retrieved,
* or the tool may even try to retrieve data from a domain that has an invalid index, which will lead to an error (the rc is captured).
* But the code changes are marginal and pretty straight forward, and the cases where scdmd_area.request.first_drid is handled are now enclosed by proper 'if/else' statement.
* This patch was already upstream accepted and a patched s390-tools package was build and shared in a PPA for further testing.
