Key decleration of union semun on src version

2020-10-26T17:52:28Z

__FreeBSD__ is defined by the compiler derived from the triple. When building FreeBSD 11 on a FreeBSD 12 with a CROSS_TOOLCHAIN=llvm10, __FreeBSD__ was set to 12 when building lib32 (for some reason no triple is being passed which seems to mean that we're taking default values from the build system). This in turn meant we end up with a double decleration of union semun which is a build error. Reviewed by: gshapiro, dim Differential Revision: https://reviews.freebsd.org/D26902

Merge sendmail 8.16.1 to HEAD: See contrib/sendmail/RELEASE_NOTES for details

2020-07-15T18:28:54Z

Includes build infrastructure & config updates required for changes in 8.16.1 MFC after: 5 days

Plug possible memory leaks in the previous patch.

Two DH_free() calls were accidentally removed. Pointyhat to: jkim

Do not free p and g parameters after calling DH_set0_pqg(3).

2020-02-27T22:36:16Z

It is specifically mentioned in the manual page. Note it has no functional change in reality because DH_set0_pqg() cannot fail when both p and g are not NULL.

Fix style inconsistencies near our OpenSSL 1.1.x patch.

Fix a white space.

Fix broken STARTTLS when SharedMemoryKey is enabled.

2020-02-27T19:40:29Z

OpenSSL 1.1 API patch for sendmail had a bug which prevented sm_RSA_generate_key() function from working. This function is used to generate a temporary RSA key for a shared memory region used for TLS processing. Note that 12.0 and 12.1-RELEASE include this bug. This affects only if SM_CONF_SHM compile-time option (enabled by default) and SharedMemoryKey run-time option (not enabled by default) in a .cf file are specified. The latter corresponds to confSHARED_MEMORY_KEY in a .mc file. PR: 242861 MFC after: 3 days Differential Revision: https://reviews.freebsd.org/D23734

Fix various -Wpointer-compare warnings

2019-10-08T21:14:09Z

This warning (comparing a pointer against a zero character literal rather than NULL) has existed since GCC 7.1.0, and was recently added to Clang trunk. Almost all of these are harmless, except for fwcontrol's str2node, which needs to both guard against dereferencing a NULL pointer (though in practice it appears none of the callers will ever pass one in), as well as ensure it doesn't parse the empty string as node 0 due to strtol's awkward interface.
