[Buildroot] [PATCH 2/2] package/samba4: bump version to 4.14.2

[Yann E. MORIN <yann.morin.1998@free.fr>]

On 2021-03-27 18:13 +0100, Bernd Kuhls spake thusly:
> Added patch to fix build error.
> Removed patch which was applied upstream.
> 
> Added two options to samba4-cache.txt to fix cross build.

Please explain why you used those specific values for thos e two
options, see below...

> host-perl is now mandatory, also host-perl-parse-yapp is needed.
> 
> Added option to fix build without dbus, this change needed a rework of
> the shared-modules configure option, due to this upstream commit:
> https://gitlab.com/samba-team/devel/samba/-/commit/b6805d5e0bcf1716f87e84bcbb2fd8f93c38a8a3

So, those two options are abotu cryptography stuff, and so this is
pretty much tricky... We really need those values to be explained, at
least in the commit log, and if possible, with a comment in the cache
file.

Extraneous space just before the option.

Also see below for another issue with this line...

Usually, we want to be symetric, so we should have:

    SAMBA4_SHARED_MODULES += !idmap_ad

Finally, the way SAMBA4_SHARED_MODULES is used, --with-shared-modules
will get a space-separated list of items, but it is not quoted when
expanded, above (quoted here again:

    --with-shared-modules=$(SAMBA4_SHARED_MODULES)

So if both vfs_snapper and idmap_ad are enabled, I doubt that will
behave as expected... Furthermore, --with-shared-modules is expected to
be comma-separated:

    https://gitlab.com/samba-team/devel/samba/-/blob/master/source3/wscript#L32

    Comma-separated list of names of modules to build shared. [...]

So you probably want something like:

    --with-shared-modules=$(subst $(space),$(comma),$(strip $(SAMBA4_SHARED_MODULES)))
