| * | util, pif: Replace sock_l4() with pif_sock_l4() | David Gibson | 2024-09-25 | 1 | -0/+42 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The sock_l4() function is very convenient for creating sockets bound to a given address, but its interface has some problems. Most importantly, the address and port alone aren't enough in some cases. For link-local addresses (at least) we also need the pif in order to properly construct a socket adddress. This case doesn't yet arise, but it might cause us trouble in future. Additionally, sock_l4() can take AF_UNSPEC with the special meaning that it should attempt to create a "dual stack" socket which will respond to both IPv4 and IPv6 traffic. This only makes sense if there is no specific address given. We verify this at runtime, but it would be nicer if we could enforce it structurally. For sockets associated specifically with a single flow we already replaced sock_l4() with flowside_sock_l4() which avoids those problems. Now, replace all the remaining users with a new pif_sock_l4() which also takes an explicit pif. The new function takes the address as an inany *, with NULL indicating the dual stack case. This does add some complexity in some of the callers, however future planned cleanups should make this go away again. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> | ||||
| * | flow: Common address information for target side | David Gibson | 2024-07-19 | 1 | -0/+40 |
| | | | | | | | | | | | | | | | | Require the address and port information for the target (non initiating) side to be populated when a flow enters TGT state. Implement that for TCP and ICMP. For now this leaves some information redundantly recorded in both generic and type specific fields. We'll fix that in later patches. For TCP we now use the information from the flow to construct the destination socket address in both tcp_conn_from_tap() and tcp_splice_connect().

| * | pif: Add helpers to get the name of a pif | David Gibson | 2023-12-04 | 1 | -0/+21 |
| Future debugging will want to identify a specific passt interface. We make a distinction in these helpers between the name of the *type* of pif, and name of the pif itself. For the time being these are always the same thing, since we have at most instance of each type of pif. However, that might change in future.
