* [SERVER] Reload server config on SIGHUPSimon Rettberg2018-07-101-0/+1
| | | | | | | Most config settings can now be changed at runtime using SIGHUP. This currently excludes the basePath, listenPort, and the client and image count limits, as well as vmdkLegacyMode.
* [SERVER] Refactor uplink/cache handling, improve crc checkingSimon Rettberg2018-07-041-1/+1
| | | | | | | | | | | | | The cacheFd is now moved to the uplink data structure and will only be handled by the uplink thread. The integrity checker now supports checking all blocks of an image. This will be triggered automatically whenever a check for a single block failed. Also, if a crc check on startup fails, the image won't be discarded anymore, but rather a full check will be initiated. Furthermore, when calling image_updateCacheMap() on an image that was previously complete, the cache map will now be re-initialized, and a new uplink connection created.

* [SERVER] Add --errormsg to only serve HTTP-JSON error codeSimon Rettberg2017-11-021-29/+51
| | | | | This could have been an external tool, but this didn't add much code and has the benefit of honoring the config file for port and bind address.

* [SERVER] Add AFL supportSimon Rettberg2017-10-301-3/+36
| | | | | | | | | | | AFL is an instrumenting fuzzer. It expects to pass input to the program to be tested via command line (file name) or via stdin. This adds support for reading messages that normally would arrive via network directly from stdin. In this mode, the server is pretty useless otherwise. http://lcamtuf.coredump.cx/afl/

* [SERVER] Reload images in another thread when triggered by signalSimon Rettberg2015-05-121-6/+12
| | | | | | | The server used to reload all images on the main thread, which is also responsible for accepting connections. While reloading the list, no new connections were accepted, which lead to clients marking the server as bad during their RTT measurements, then switching away from it.
