* Fix the broken "avoid unaligned data" fix. The problem is that the builtinpeter2002-08-101-2/+2
| | | | | | | | | | | | | | | | | | gcc memcpy "knows" about types that are supposed to be actually already aligned and triggers alignment errors doing the memcpy itself. "Fix" this by changing it to a bcopy(). In this case, we had: struct timeval *tp; struct timeval tv1; memcpy(&tv1,tp,sizeof(tv1)); .. and since gcc *knows* that a pointer to a timeval is longword aligned and that tv1 is longword aligned, then it can use an inline that assumes alignment. The following works too: cp = (char *)tp; memcpy(&tv1,cp,sizeof(tv1)); Simply casting (char *)tp for the memcpy doesn't work. :-( This affected different 64 bit platforms in different ways and depends a lot on gcc as well. I've seen this on alpha and ia64 at least, although alpha isn't doing it right now.

| | | | | | | | | | | | | right; after a single packet was dropped it beeped after every transmission. Change its implementation to only output a bell when there is an increase in the maximum value of the number of packets that were sent but not yet received. This has the benefit that even for very long round-trip times, ping -A will do roughly the right thing after a few inital false-positives. Reviewed by: ru

* Ian Dowse writes:mjacob2001-07-071-16/+7
| | | | | | | | | | | The original code was certainly broken; it knows that whereto is to be used for a sockaddr_in, so it should be declared as such. To support multiple protocols, there is also a sockaddr_storage struct that can be used; I don't think struct sockaddr is supposed to be used anywhere other than for casts and pointers.

* Fix unaligned access faults on alpha.mjacob2001-07-071-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This one is strange and goes against my rusty compiler knowledge. The global declaration struct sockaddr whereto; produces for both i386 && alpha: .comm whereto,16,1 which means common storage, byte aligned. Ahem. I though structs were supposed to be ALDOUBLE always? I mean, w/o pragma packed? Later on, this address is coerced to: to = (struct sockaddr_in *)&whereto; Up until now, we've been fine on alpha because the address just ended up aligned to a 4 byte boundary. Lately, though, it end up as: 0000000120027b0f B whereto And, tra la, you get unaligned access faults. The solution I picked, in lieu of understanding what the compiler was doing, is to put whereto as a union of a sockaddr and sockaddr_in. That's more formally correct if somewhat awkward looking.
