Subject: [PATCH] ipa_cldap: fix memory leak
|
|
|
b7b64b |
|
|
|
b7b64b |
ipa_cldap_encode_netlogon() allocates memory to store binary data as part of
|
|
|
b7b64b |
berval (bv_val) when processing a CLDAP packet request from a worker. The
|
|
|
b7b64b |
data is used by ipa_cldap_respond() but bv_val is not freed later on.
|
|
|
b7b64b |
|
|
|
b7b64b |
This commit is adding the corresponding free() after ipa_cldap_respond()
|
|
|
b7b64b |
is completed.
