On all Unix platforms, link libexecinfo as system library,
if it contains backtrace_symbols_fd function, and libc does not contain
this function
Also remove cmake/os/OpenBSD.cmake, as after the fix it serves no purpose.
Summary of changes
- MD_CTX_SIZE is increased
- EVP_CIPHER_CTX_buf_noconst(ctx) does not work anymore, points
to nobody knows where. The assumption made previously was that
(since the function does not seem to be documented)
was that it points to the last partial source block.
Add own partial block buffer for NOPAD encryption instead
- SECLEVEL in CipherString in openssl.cnf
had been downgraded to 0, from 1, to make TLSv1.0 and TLSv1.1 possible
(according to https://github.com/openssl/openssl/blob/openssl-3.0.0/NEWS.md
even though the manual for SSL_CTX_get_security_level claims that it
should not be necessary)
- Workaround Ssl_cipher_list issue, it now returns TLSv1.3 ciphers,
in addition to what was set in --ssl-cipher
- ctx_buf buffer now must be aligned to 16 bytes with openssl(
previously with WolfSSL only), ot crashes will happen
- updated aes-t , to be better debuggable
using function, rather than a huge multiline macro
added test that does "nopad" encryption piece-wise, to test
replacement of EVP_CIPHER_CTX_buf_noconst
part of MDEV-29000
Table_cache_instance: Define the structure aligned at
the CPU cache line, and remove a pad[] data member.
Krunal Bauskar reported this to improve performance on ARMv8.
aligned_malloc(): Wrapper for the Microsoft _aligned_malloc()
and the ISO/IEC 9899:2011 <stdlib.h> aligned_alloc().
Note: The parameters are in the Microsoft order (size, alignment),
opposite of aligned_alloc(alignment, size).
Note: The standard defines that size must be an integer multiple
of alignment. It is enforced by AddressSanitizer but not by GNU libc
on Linux.
aligned_free(): Wrapper for the Microsoft _aligned_free() and
the standard free().
HAVE_ALIGNED_ALLOC: A new test. Unfortunately, support for
aligned_alloc() may still be missing on some platforms.
We will fall back to posix_memalign() for those cases.
HAVE_MEMALIGN: Remove, along with any use of the nonstandard memalign().
PFS_ALIGNEMENT (sic): Removed; we will use CPU_LEVEL1_DCACHE_LINESIZE.
PFS_ALIGNED: Defined using the C++11 keyword alignas.
buf_pool_t::page_hash_table::create(),
lock_sys_t::hash_table::create():
lock_sys_t::hash_table::resize(): Pad the allocation size to an
integer multiple of the alignment.

submodules.cmake: don't use "--depth 1" with old Git
Old Git may not work with "--depth 1" when the referenced commit hash
is far from HEAD.
Newer Git improves the situation. For example:
fb43e31f2b
It's safe to not use "--depth 1" with old Git.
Closes#2049
Fixed inlining flags. Remove /Ob1 added by CMake for RelWithDebInfo.
(the actual compiler default is /Ob2 if optimizations are enabled)
Allow to define custom /Ob flag with new variable MSVC_INLINE, if desired
The warning reads:
CMake Deprecation Warning at CMakeLists.txt:101 (CMAKE_MINIMUM_REQUIRED):
Compatibility with CMake < 2.8.12 will be removed from a future version of
CMake.
Add SYSTEMD_READWRITEPATH-variable to mariadb{@,}.service.in to make sure that
if one is not building RPM or DEB packages then make sure there is ReadWritePaths
directive is defined in systemd service file.
This ensures that tar-ball installation has permissions to write database default
installation path (default: /usr/local/mysql/data) even if it's located
under /usr. Writing to that location is prevented by 'ProtectSystem=full'
systemd directive by default.
Prefixing the path with "-" in systemd causes there to not be an error if the
path doesn't exist. This may occur if the user has configured a datadir
elsewhere.
