Subject: tests: Run test cases that read process memory in the beginning
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=738ff9beef0e03c84a3064ee497dd18af4b5bb1d;p=thirdparty%2Fhostap.git

tests: Run test cases that read process memory in the beginning

Those test cases seem to have some resource issues (i.e., taking
unexpectedly large amount of memory) with newer software versions
(showed up when upgrading from Ubuntu 22.04 to 24.04; maybe due to newer
python3 version?). This might be related to memory fragmentation and
allocated memory from hostapd/wpa_supplicant not getting fully freed in
a sense of minimizing the read process memory. Running the key lifetime
test cases in the beginning of each VM seems to avoid resource issues,
so reorder the test cases to do that.
