- Remove macros that covertly create epoch_tracker on thread stack. Such macros a quite unsafe, e.g. will produce a buggy code if same macro is used in embedded scopes. Explicitly declare epoch_tracker always. - Unmask interface list IFNET_RLOCK_NOSLEEP(), interface address list IF_ADDR_RLOCK() and interface AF specific data IF_AFDATA_RLOCK() read locking macros to what they actually are - the net_epoch. Keeping them as is is very misleading. They all are named FOO_RLOCK(), while they no longer have lock semantics. Now they allow recursion and what's more important they now no longer guarantee protection against their companion WLOCK macros. Note: INP_HASH_RLOCK() has same problems, but not touched by this commit. This is non functional mechanical change. The only functionally changed functions are ni6_addrs() and ni6_store_addrs(), where we no longer enter epoch recursively. Discussed with: jtl, gallatin |
