memory leak

[GBert]

Hi Bjoern,

nice tiny snmp agent. I'm using it to monitor my EDL21 capable power meter.
Anyway, I saw a memory leak. 'decode_oid' allocates a string which is never freed.

Follwowing patch will fix it:

diff --git a/snmp.c b/snmp.c
index 92b2474..caf4d8b 100644
--- a/snmp.c
+++ b/snmp.c
@@ -648,6 +648,7 @@ void clr_varbind_list_rx(struct varbind_list_rx *varbind_list)
        unsigned int i;

        for(i=(varbind_list->varbind_idx);i>0;i--){
+               free(varbind_list->varbind_list[i-1]->oid)
                free(varbind_list->varbind_list[i-1]->value);
                free(varbind_list->varbind_list[i-1]);
        }

Regards

Gerd
