Net patches should be sent to netdev@vger.kernel.org and perhaps linux-kernel@vger.kernel.org. But whatever - I can convert this patch into a suitable one and send it in to David if people think it is good?

Linus's current tree has out_hdr->sadb_msg_type = SADB_GETSPI; there which I assume has fixed this issue, so I'll close the report, thanks.
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob_plain;f=net/key/af_key.c;hb=HEAD Still shows the pfkey_get function setting PFKEY_DUMP... Second, PFKEY_GETSPI is not PFKEY_GET - it really needs to be PFKEY_GET so dispatch functions on the PF_KEY socket can do the right thing when the send messages down to the kernel and are expecting a match to be returned per the RFC...

Please send a patch as per http://www.zip.com.au/~akpm/linux/patches/stuff/tpp.txt to netdev@vger.kernel.org and akpm@linux-foundation.org, thanks.
