| H A D | cc_newreno.c | diff 218167 Tue Feb 01 13:47:40 MST 2011 lstewart Algorithm modules can define their own private congestion signal types in the top 8 bits of the 32 bit signal bit field space for internal use. These private signals should not be leaked outside of a module. Given that many algorithm modules use the NewReno hook functions to simplify their implementation, the obvious place such a leak would show up is in the NewReno cong_signal hook function. - Show the full number of significant bits in the signal type definitions in <netinet/cc.h>. - Add a bitmask to simplify figuring out if a given signal is in the private or public bit range. - Add a sanity check in newreno_cong_signal() to ensure private signals are not being leaked into the hook function.
