failure in /olver/util/crypt/tests/crypt_spec 1

[Jeff Johnson]

with Fedora glibc there is a failure in crypt_spec 1 subtest.

Message from the test:

failure 1
--------------------------------
POSTCONDITION_FAILED
Requirement failed: Unexpected error code returned: [EINVAL] code 0x16

LSB test suite calls invalid salt such as "". According to documentation if
salt doesn't match supported '$x$...' format (where X is a number, e.g. 1 for
MD5) it fallbacks to DES. But DES expects the salt to be 2 chars long (or
longer, the rest is ignored). Therefore salt "" or "X" is invalid. Upstream
changed the behaviour for invalid salt and crypt() returns NULL pointer in case
of invalid salt.
