調査の方向性
Start by reading the linked Valgrind log and the CI configuration that runs the tests; the report names OSSLRNG.cpp, OSSLRSA.cpp, and calls through OpenSSL’s DRBG and AES routines. Check whether the warnings reproduce with the upstream SoftHSM version and identify which reports originate in SoftHSM versus its dependencies. Done means the warnings are understood and any upstream issue has a reproducible resolution.

説明
In our CI pipeline, we are receiving a lot of problems from valgrinds memory checker in SoftHSM (softhsm2=2.6.1-2.2ubuntu3). However, I'm unsure if they apply to the upstream version of SoftHSM
The full log can be found here log.txt (search for "insert_a_suppression_name_here")
Here are some examples from the log (the full log is too long to be displayed here):
