Peter Oskolkov eedbbb0d98 net: dccp: initialize (addr,port) listening hashtable ... Commit d9fbc7f643 "net: tcp: prefer listeners bound to an address" removes port-only listener lookups. This caused segfaults in DCCP lookups because DCCP did not initialize the (addr,port) hashtable. This patch adds said initialization. The only non-trivial issue here is the size of the new hashtable. It seemed reasonable to make it match the size of the port-only hashtable (= INET_LHTABLE_SIZE) that was used previously. Other parameters to inet_hashinfo2_init() match those used in TCP. V2 changes: marked inet_hashinfo2_init as an exported symbol so that DCCP compiles when configured as a module. Tested: syzcaller issues fixed; the second patch in the patchset tests that DCCP lookups work correctly.
