At the moment Linux Kernel 3.2 is the last supported LTS. It comes without AF_VSOCK support (added only in 3.10), therefore old libcs, such as glibc before 2.18 does not provide, cause ss(8) tool build failures like following:
ss.c:294:15: error: 'AF_VSOCK' undeclared here (not in a function) ss.c:323:2: error: array index in initializer not of integer type ss.c:323:2: error: (near initialization for 'default_afs') make[1]: *** [ss.o] Error 1 make[1]: *** Waiting for unfinished jobs.... make: *** [all] Error 2 Provide AF_VSOCK and PF_VSOCK defines for compatibility; adjust AF_MAX and PF_MAX to reflect change. Tested in Debian 7 (Wheezy) environment with glibc-2.13 and Linux Kernel 3.2. Still supported config until 31 May 2018 according to Debian LTS support page.
