Lawrence Stewart 9891578a40 Plug a memory leak and potential NULL-pointer dereference introduced in r331214. ... Each TCP connection that uses the system default cc_newreno(4) congestion control algorithm module leaks a "struct newreno" (8 bytes of memory) at connection initialisation time. The NULL-pointer dereference is only germane when using the ABE feature, which is disabled by default. While at it: - Defer the allocation of memory until it is actually needed given that ABE is optional and disabled by default. - Document the ENOMEM errno in getsockopt(2)/setsockopt(2). - Document ENOMEM and ENOBUFS in tcp(4) as being synonymous given that they are used interchangeably throughout the code. - Fix a few other nits also accidentally omitted from the original patch.
