Subject: [PATCH] Remove strerror() calls from k5_get_error()
|
|
|
|
Coverity models strerror() as a function which cannot accept negative
|
|
values, even though it has defined behavior on all integers.
|
|
k5_get_error() contains code to call strerror_r() and strerror() if
|
|
its fptr global is unset, which isn't an expected case in practice.
|
|
To silence a large number of Coverity false positives, just return a
|
|
fixed string if fptr is null.
|
|
|
|
(cherry picked from commit 2d400bea7a81a5a834a1be6ded439f18e0afa5ba)
