| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | size we receive here should fit into the receive buffer. Unfortunately, there's no 100% foolproof way to distinguish a ridiculously large record size that a client actually meant to send us from a ridiculously large record size that was sent as a spoof attempt. The one value that we can positively identify as bogus is zero. A zero-sized record makes absolutely no sense, and sending an endless supply of zeroes will cause the server to loop forever trying to fill its receive buffer. Note that the changes made to readtcp() make it okay to revert this sanity test since the deadlock case where a client can keep the server occupied forever in the readtcp() select() loop can't happen anymore. This solution is not ideal, but is relatively easy to implement. The ideal solution would be to re-arrange the way dispatching is handled so that the select() loop in readtcp() can be eliminated, but this is difficult to implement. I do plan to implement the complete solution eventually but in the meantime I don't want to leave the RPC library totally vulnerable. That you very much Sun, may I have another.

* | Improve DoS avoidance in RPC stream oriented transports. The TCP transportBill Paul1998-05-182-34/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | uses readtcp() to gather data from the network; readtcp() uses select(), with a timeout of 35 seconds. The problem with this is that if you connect to a TCP server, send two bytes of data, then just pause, the server will remain blocked in readtcp() for up to 35 seconds, which is sort of a long time. If you keep doing this every 35 seconds, you can keep the server occupied indefinitely. To fix this, I modified readtcp() (and its cousin, readunix() in svc_unix.c) to monitor all service transport handles instead of just the current socket. This allows the server to keep handling new connections that arrive while readtcp() is running. This prevents one client from potentially monopolizing a server. Also, while I was here, I fixed a bug in the timeout calculations. Someone attempted to adjust the timeout so that if select() returned EINTR and the loop was restarted, the timeout would be reduced so that rather than waiting for another 35 seconds, you could never wait for more than 35 seconds total. Unfortunately, the calculation was wrong, and the timeout could expire much sooner than 35 seconds. Notes: svn path=/head/; revision=36156

* | Patch RPC library to avoid possible denial of service attacks as describedBill Paul1998-05-151-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | recently in BUGTRAQ. The set_input_fragment() routine in the XDR record marking code blindly trusts that the first two bytes it sees will in fact be an actual record header and that the specified size will be sane. In fact, if you just telnet to a listening port of an RPC service and send a few carriage returns, set_input_fragment() will obtain a ridiculously large record size and sit there for a long time trying to read from the network. A sanity test is required: if the record size is larger than the receive buffer, punt. Notes: svn path=/head/; revision=36087
