* [*] Introduce constants for IPv4/6 in dnbd3_host_tSimon Rettberg2017-10-282-16/+16
| | | | | | | AF_INET luckily was "2" on all platforms checked, so no problems there with interoperation, but AF_INET6 is different between Linux, BSD, Windows and possibly others, so map back and forth between AF_INET/AF_INET6 and HOST_IP4/HOST_IP6 to fix this.
* [KERNEL] version check to support pointer to backing_dev_info in request_queueSimon Rettberg2017-10-091-0/+6
| | | | | This changed in 4.11, see https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=dc3b17cc8bf21307c7e076e7c778d5db756f7871
* [*] Continue splitting #defines to clientconfig.h etc.Simon Rettberg2017-09-023-0/+3
|
* [KERNEL] PAGE_CACHE_SIZE -> PAGE_SIZESimon Rettberg2016-10-171-1/+1
| | | | | | | These two have been the same all along and recently, the _CACHE variant has been removed (kernel 4.6). Switch to the non-CACHE version so build doesn't break on newer kernels.
* [KERNEL/CLIENT] Several minor tweaks and changesSimon Rettberg2016-01-113-13/+13
| | | | | | | | | | - Disable panic timeout that reports errors to block layer by default - Get rid of "is_server" used by old proxy mode, introduce "honor_server_alts" that just controls whether we use alts provided by the server - Allow switching servers when we only have 3 RTT measurements - If using alts provided by server, don't ignore those that come from other servers than the initial one
* [KERNEL] Add support for kernel 4.2.xSimon Rettberg2015-10-132-2/+12
|
* Get rid of unneccessary volatileSimon Rettberg2015-02-221-2/+2
| | | | Some minor debugging code, mostly commented out
* [SERVER] Crank up warning levels of gcc and fix them all (mostly sign ↵Simon Rettberg2015-01-141-1/+4
| | | | | | | compare and some unused params) Also allow newline at end of alt-servers file without complaining about it not being a valid alt server definition.

* [KERNEL] Tweak better server selection a bit by also adding a constant delay ↵Simon Rettberg2013-10-241-1/+1
| | | | (1,5ms)
* [KERNEL] Slow down with RTT measurements after 30 secondsSimon Rettberg2013-10-242-6/+22
| | | | | | | Right after connecting, all servers will be polled every 4 seconds for 30 seconds, so we get 7 data points per alt-server. If no better server is found during this time, further RTT measurements will be done every 22 seconds, to put less load on the network in the long run.
