Please review this patch that fixes a memory leak in P11TlsPrfGenerator, which is triggered during TLS1.2 Finished message generation and verification.
The patch changes C_SignInit JNI method to free the mechanism data immediately after use. This matches the behavior of other Init methods (like C_EncryptInit). The patch also fixes a similar issue in other signature-related methods. The change essentially reverts part of [JDK-8080462](https://bugs.openjdk.org/browse/JDK-8080462). All sun/security/pkcs11 tests still pass with NSS 3.35 and 3.91. All tier1-3 tests still pass. ------------- Commit messages: - Free the mechanism parameters early Changes: https://git.openjdk.org/jdk/pull/17584/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=17584&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8324585 Stats: 83 lines in 6 files changed: 0 ins; 65 del; 18 mod Patch: https://git.openjdk.org/jdk/pull/17584.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/17584/head:pull/17584 PR: https://git.openjdk.org/jdk/pull/17584
