![]() The SMR-protected inpcb lookup algorithm currently has to check whether
a matching inpcb belongs to a jail, in order to prioritize jailed
bound sockets. To do this it has to maintain a ucred reference, and for
this to be safe, the reference can't be released until the UMA
destructor is called, and this will not happen within any bounded time
period.
Changing SMR to periodically recycle garbage is not trivial. Instead,
let's implement SMR-synchronized lookup without needing to dereference
inp_cred. This will allow the inpcb code to free the inp_cred reference
immediately when a PCB is freed, ensuring that ucred (and thus jail)
references are released promptly.
