Thanks for the patch collection - that made it easier to review them.
#6 and #5:
* An SnmpAdminString is no more than 255 octets, so the tmp buffer
is unnecessarily big, maxlen * 2 + 2 (0x) + 1 (\0) = 513 bytes
is enough.
* I still fail to understand why you prefer to write 1024 NUL's to
the tmp buffer before reading the value instead of writing a
single NUL to it after having read the value, and in the case of
read_config_save_octet_value the output is a NUL-terminated
string in any case so there is no reason for it at all there.
#4:
* A variant of #6 and #5. The buffer to
read_config_save_octet_string is not big enough at only 512
bytes.
* Tricky and Important: Earlier the value FOO matched a string
with value FOO but with your patch it matches the string "FOO".
This changes the interface of the agent.
Thanks for doing this work.
