* | [*] Introduce constants for IPv4/6 in dnbd3_host_t | Simon Rettberg | 2017-10-28 | 2 | -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_queue | Simon Rettberg | 2017-10-09 | 1 | -0/+6 |
| | | | | | This changed in 4.11, see https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=dc3b17cc8bf21307c7e076e7c778d5db756f7871 | ||||

* | [KERNEL] PAGE_CACHE_SIZE -> PAGE_SIZE | Simon Rettberg | 2016-10-17 | 1 | -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 changes | Simon Rettberg | 2016-01-11 | 3 | -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.x | Simon Rettberg | 2015-10-13 | 2 | -2/+12 |

* | [SERVER] Crank up warning levels of gcc and fix them all (mostly sign ↵ | Simon Rettberg | 2015-01-14 | 1 | -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] Slow down with RTT measurements after 30 seconds | Simon Rettberg | 2013-10-24 | 2 | -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. | ||||
