Subject: [PATCH] nss: improve error handling in Curl_nss_random()
|
||||
|
||||
The vtls layer now checks the return value, so it is no longer necessary
|
||||
to abort if a random number cannot be provided by NSS. This also fixes
|
||||
the following Coverity report:
|
||||
|
||||
Error: FORWARD_NULL (CWE-476):
|
||||
lib/vtls/nss.c:1918: var_compare_op: Comparing "data" to null implies that "data" might be null.
|
||||
lib/vtls/nss.c:1923: var_deref_model: Passing null pointer "data" to "Curl_failf", which dereferences it.
|
||||
lib/sendf.c:154:3: deref_parm: Directly dereferencing parameter "data".

||||

Subject: [PATCH] nss: do not skip Curl_nss_seed() if data is NULL
|
||||
|
||||
In that case, we only skip writing the error message for failed NSS
|
||||
initialization (while still returning the correct error code).
