From: Andrew Yourtchenko Date: Thu, 9 Aug 2018 13:30:57 +0000 (+0200) Subject: acl-plugin: fix failures in some of IPv4 test-debug testcases X-Git-Tag: v18.10-rc1~469 X-Git-Url: https://gerrit.fd.io/r/gitweb?a=commitdiff_plain;h=7fad624b09f8d1256360222dc547519d8b40dd1c;p=vpp.git acl-plugin: fix failures in some of IPv4 test-debug testcases Commit 1c7bf5d41737984907e8bad1dc832eb6cb1d6288 added the poisoning of the newly freed memory in debug builds, exposing a logic error in mask assignment code - it passed a pointer to within a pool to a function which might potentially expand the pool. This resulted in a failure of the test in the debug version. Fix that by making a local copy of the value before passing a pointer to it.
