--------------------------------
Summary: Cannot decode HostAddress using CredCacheInputStream
Key: DIRKRB-777
URL: https://issues.apache.org/jira/browse/DIRKRB-777
Project: Directory Kerberos
Issue Type: Bug
Affects Versions: 2.1.0
Reporter: Guotao Yu
In CredCacheOutputStream, HostAddress is serialized in this way.
{code:java}
public void writeAddress(HostAddress address) throws IOException {
write(address.getAddrType().getValue());
write(address.getAddress().length);
write(address.getAddress(), 0,
address.getAddress().length);
} {code}
HostAddrType is serialized as an int type, However, in CredCacheInputStream, it
is read as a short type.
{code:java}
public HostAddress readAddress() throws IOException {
int typeValue = readShort();
HostAddrType addrType = HostAddrType.fromValue(typeValue);
if (addrType == HostAddrType.NONE) {
throw new IOException("Invalid host address type");
}
byte[] addrData = readCountedOctets();
if (addrData == null) {
throw new IOException("Invalid host address data");
}
HostAddress addr = new HostAddress();
addr.setAddrType(addrType);
addr.setAddress(addrData);
return addr;
} {code}
This results in the deserialized HostAddrType being an illegal type.
So for me the library is unusable.
