zstd: Move to a new zstd package

2026-01-06T04:24:59+00:00

Zstd is a discrete, self-contained system component.  To match how we
package zlib, bzip2 and xz, move it to its own package, with a separate
lib package.

Add the new package to the minimal set, since this is a core component
that users expect to be installed.

This change adds a new package to the system so, until we have a proper
policy on how to handle this in release/stable branches, it should not
be MFC'd.

src: Use gnu17 as the default C standard for userland instead of gnu99

2025-02-11T14:16:25+00:00

Tracking newer versions of C (and C++) permits assuming newer language
features in the base system.  Some C11 extensions are already used in
the base system but implemented on top of GNU C extensions such as
_Alignas and _Static_assert.  In some cases the fallback versions in
cdefs.h are more limited than the native C11 extensions.

Even though C11 is the next major version of C, C17 is chosen instead
since C17 does not add new features to C but merely fixes defects in
C11.  It is also well supported by a wide range of clang (7.0.0+) and
GCC (8.1+) versions.

Along with changing the default, this change also removes explicit
requests for c11 via the CSTD variable in various Makefiles.

Libraries and binaries for ZFS continue to use c99.

Only set WARNS if not defined

This would allow interested parties to do experimental runs with an
environment set appropriately to raise all the warnings throughout the
build; e.g. env WARNS=6 NO_WERROR=yes buildworld.

Update to Zstandard 1.3.8

2018-12-29T21:18:01+00:00

This merge brings in a couple new files, which needed to be attached to the
build; a new dependency on , which must be stubbed; and a name
change in the Context parameter constants, from ZSTD_p_foo to ZSTD_c_foo.

Significantly, it fixes a kernel build error with GCC where floating-point
functions were included in the kernel build, by hiding them under the same
compile-time #ifdef that already covered their invocation.  That issue was
introduced to FreeBSD in the 1.3.7 update and tracked upstream here:

  https://github.com/facebook/zstd/issues/1386
