Hello cron2, flichtenheld, plaisthos,
I'd like you to reexamine a change. Please visit
http://gerrit.openvpn.net/c/openvpn/+/1089?usp=email
to look at the new patch set (#8).
Change subject: multipeer: introduce asymmetric peer-id
..
multipeer: introduce asymmetric peer-id
In order to achieve a multipeer functionality, peers now
use separate IDs for sending (tx_peer_id) and receiving
(rx_peer_id).
Each peer announces its own ID through pushing peer-info
using 'ID=7f1' hex format so identification can still
happen even if IP/port changes.
In P2P mode, peer switch to using the announced IDs after
mutual exchange.
In P2MP mode, clients always announce their ID, and servers
can optionally respond with their own to enable the same
behavior.

Hello cron2, flichtenheld, plaisthos,
I'd like you to reexamine a change. Please visit

multipeer: introduce asymmetric peer-id
In order to achieve a multipeer functionality, peers now
use separate IDs for sending (tx_peer_id) and receiving
(rx_peer_id).
Each peer announces its own ID through pushing peer-info
using 'ID=7f1' hex format so identification can still
happen even if IP/port changes.
In P2P mode, peer switch to using the announced IDs after
mutual exchange.
In P2MP mode, clients always announce their ID, and servers
can optionally respond with their own to enable the same
behavior.

Patch Set 4: Code-Review-2
(8 comments)
Patchset:
PS4:
The part that picks the "peer-id" pushed and parsed options.c that sets peer-id
on receiving peer-id
if (found & OPT_P_PEER_ID)
{
msg(D_PUSH_DEBUG, "OPTIONS IMPORT: peer-id set");
c->c2.tls_multi->use_peer_id = true;
c->c2.tls_multi->tx_peer_id = c->options.peer_id;
}
should probably also be adjusted to set both rx and tx as peer-id as pushed
option should set both.
File src/openvpn/ssl.c:
http://gerrit.openvpn.net/c/openvpn/+/1089/comment/7b89f526_1248648b?usp=email :
PS4, Line 1179: ret->rx_peer_id = MAX_PEER_ID;
Add comment here that we also use the rx peer id to identify DCO clients as
this has become now a important distinction.
http://gerrit.openvpn.net/c/openvpn/+/1089/comment/18e30fd6_0e66350f?usp=email :
PS4, Line 1982: }
This is still not guarded by DCO capability. With the current version we still
always indicate to the peer that we are always asymmetric peer ID capable even
if the underlying DCO module is not able to use a different peer ID for TX.
http://gerrit.openvpn.net/c/openvpn/+/1089/comment/3fb67b50_b42dfeaf?usp=email :
PS4, Line 2165: if (multi->rx_peer_id == MAX_PEER_ID && session->opt->mode
!= MODE_SERVER)
This feel be a very hacky place to set the multi rx peer id. I think there is a
better place to do that.

http://gerrit.openvpn.net/c/openvpn/+/1089/comment/c5df3a60_53fab78f?usp=email :

This also need to take DCO capability into account.
http://gerrit.openvpn.net/c/openvpn/+/1089/comment/1a14b321_0b6cf1e1?usp=email :
PS4, Line 450: if (multi->use_peer_id)
I think this parts needs to be skipped if we are using/negotiated asymmetric
peer-id as it would overwrite both rx and tx ids with the EKM generated ones.
Probably move the if (tx_peer_id) above and have this as else path with a
comment that asymmetric peer id trumps EKM

0 is a valid peer id. So I would rather have -1 (and int32_t as return type) or
MAX_PEER_ID, MAX_UINT value or similar as not defined.
In fact the first client that typically connects to a p2mp server is assigned

Hello flichtenheld, plaisthos,
I'd like you to reexamine a change. Please visit
http://gerrit.openvpn.net/c/openvpn/+/1089?usp=email
to look at the new patch set (#2).
The following approvals got outdated and were removed:
Code-Review-1 by flichtenheld
Change subject: multipeer: introduce asymmetric peer-id
..
multipeer: introduce asymmetric peer-id
In order to achieve a multipeer functionality, peers now
use separate IDs for sending (tx_peer_id) and receiving
(rx_peer_id).
Each peer announces its own ID through pushing peer-info
using 'ID=7f1' hex format so identification can still
happen even if IP/port changes.
In P2P mode, peer switch to using the announced IDs after
mutual exchange.
In P2MP mode, clients always announce their ID, and servers
can optionally respond with their own to enable the same
behavior.

multipeer: introduce asymmetric peer-id
In order to achieve a multipeer functionality, peers now
use separate IDs for sending (tx_peer_id) and receiving
(rx_peer_id).
Each peer announces its own ID through pushing peer-info
using 'ID=7f1' hex format so identification can still
happen even if IP/port changes.
In P2P mode, peer switch to using the announced IDs after
mutual exchange.
In P2MP mode, clients always announce their ID, and servers
can optionally respond with their own to enable the same
behavior.
