Applied patch to add OpenSSL3 KTLS trivial processing. Description: Patch adds trivial processing for BIO_CTRL_GET_KTLS_SEND and BIO_CTRL_GET_KTLS_RECV control commands to make tcltls working with OpenSSL 3.0. See also: - https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1006587 - https://bugzilla.redhat.com/show_bug.cgi?id=2088363 Source: https://sources.debian.org/src/tcltls/1.7.22-3/debian/patches/openssl3.patch check-in: 6f19aa6623 user: bohagan tags: trunk

Changes for OpenSSL v1.1.1 to make compatible with no deprecated option. check-in: 2ed802a7af user: bohagan tags: trunk

01:27
Initial changes for TCL 9.0. Fixed package requires to work with TCL 9.0. Removed obsolete macro _ANSI_ARGS_, use ANSI arg definitions, etc. Macros: CONST84 to const, WIN32 to _WIN32, CONST to const, VOID to void, etc. Replaced Tcl_SaveResult with Tcl_SaveInterpState, Tcl_RestoreResult with Tcl_RestoreInterpState, and Tcl_DiscardResult with Tcl_DiscardInterpState. Use Tcl_BackgroundError for pre TCL 8.6 and Tcl_BackgroundException for TCL 8.6+. check-in: 275ecbcc5d user: bohagan tags: trunk
Changes

Modified tls.c from [28a1c0e368] to [e79ec1582f].
