[Pkg-samba-maint] failing salsa reprotest job

[Michael Tokarev]

I'm seeing a failing reprotest job on salsa.
It fails at configure (!) stage when the build
is happening the second time.

Here's the failing spot (removed irrelevant info):

It fails the same way for linux thread credential test too:

                                 #define AUTOCONF_TEST 1
                                 #define HAVE_LINUX_THREAD_CREDENTIALS 1
                                 #include "../lib/util/setid.c"
                                 #include "./lib/util_sec.c"
out: Failed to set gid privileges to (-1,1) now set to (0,0) uid=(0,0)

(in the successful build/config the linux-thread-credential test work,
so it does not try setreuid test, but actuall both of them should work).

I wonder if this is due to the usage of faketime for example..

setreuid(-1,1) should Just Work for root.
