2002-10-14 Thread Bosko Milekic
Not that my opinion really holds much weight with you guys but for what it's worth, I think the change would be gratuitist. 1. MSIZE has been around forever. 2. The argument that sys/sys/mbuf.h should have MSIZE removed/changed because some other code may use it is fallacious. The "other code"

Rename of MSIZE kernel option..

2002-10-14 Thread John Baldwin
Would people be open to renaming the 'MSIZE' kernel option to something more specific such as 'MBUF_SIZE' or 'MBUFSIZE'? Using 'MSIZE' can break other places in the kernel. For example, ISA device ivars have an ivar for the size of a memory resource called 'MSIZE' and the kernel option causes br

IP_SENDSRCADDR implementation

2002-10-14 Thread Ian Dowse
It was discussed here some time ago that we should have an IP_SENDSRCADDR ancillary data type to match the IP_RECVDSTADDR socket option. This permits a server process binding to a wildcard UDP socket to select the IP address from which outgoing packets are sent on a per-datagram basis. When combi
