Chernikov Date: Mon Apr 19 20:49:18 2021 +0000 Relax rtsock message restrictions. Address multiple issues with strict rtsock message validation. D28668 "normalisation" approach was based on the assumption that we always have at least "standard" sockaddr len. It turned out to be false - certain older applications like quagga or routed abuse sin[6]_len field and set it to the offset to the first fully-zero bit in the mask. It is impossible to normalise such sockaddrs without reallocation. With that in mind, change the approach to use a distinct memory buffer for the altered sockaddrs. This allows supporting the older software while maintaining the guarantee on the "standard" sockaddrs.
