* Fix incorrect use of pubkey ptr in new_lease()Thomas Gschwantner2019-09-101-3/+16
| | | | | | | | | Before this, leases_ht would store the (temporary) pointer to pubkey that's given to new_lease() directly. The memory it's pointing to is overwritten as soon as a new connection comes in however and thus breaking the hashtable. Instead make our own copy of the pubkey and store the pointer to that.
* Fix build issue that occurs on gcc debian 6.3.0-18Thomas Gschwantner2019-08-211-1/+5

* radix-trie: implement pool shadowingThomas Gschwantner2019-08-022-27/+60
| | | | | | | | | | | | | | Pools are created from routes which can overlap. Consider the following: ip route add 192.168.4.0/28 ip route add 192.168.4.0/24 sleep 3600 ip route del 192.168.4.0/24 Here, the pool created from the first route is being shadowed by the pool from the second route. However, since the second pool is later removed again we cannot simply combine them. So instead this commit shadows them, to avoid them being double counted.
* Move counting logic from lease.c to radix-trie.cThomas Gschwantner2019-07-183-108/+94

* radix-trie: inline find_node() into ipp_addpool()Thomas Gschwantner2019-07-161-16/+8
| | | | | The way find_node() was written to suit ipp_addpool() means it's not really generic and rather confusing, so we inline it instead.
* Use epoll() instead of poll()Thomas Gschwantner2019-06-144-123/+143
| | | | | This enables us to later use the timeout parameter of epoll_wait() to timely remove expired leases.
* Remove CLOCK_MONOTONIC commentThomas Gschwantner2019-06-141-4/+0
| | | | | | The CLOCK_MONOTONIC change was reverted: https://git.kernel.org/torvalds/c/a3ed0e43

|
* Use hashtable to match ll-ip with pubkeyThomas Gschwantner2019-06-022-31/+661
| | | | | | The link-local IP is always /128, so using a hashtable is more appropriate here. We only use the lower 64 bits as key, since the first 64 bits of link-local addresses are always the same.
* Sleep lessLinus Nordberg2019-05-261-3/+5
| | | | | Only sleep after failed try_connect(), because it might fail quickly. The read should be blocking for 1s (SO_RCVTIMEO).
* Use blocking I/O in clientLinus Nordberg2019-05-261-119/+39
| | | | Avoiding the unnecessary complexity of non-blocking I/O.
* No need to clear bits in pollfd reventsLinus Nordberg2019-05-262-5/+0
| | | | | | | | POSIX says: "In each pollfd structure, poll() shall clear the revents member, except that where the application requested a report on a condition by setting one of the bits of events listed above, poll() shall set the corresponding bit in revents if the requested condition is true."

* Implement faked allocations, server sideLinus Nordberg2019-05-263-104/+433
| | | | | | | | | | Reject clients not connecting from an IPv6 address. Reject clients not connecting from the correct port. Fake address allocation. Update allowed-ips with leases handed out. Send response messages. Extend protocol to include lease start and lease time, errno and errmsg. Move common code to common.[ch].
* Specify scope id in addresses to ping6Linus Nordberg2019-02-251-2/+2
