want to add per-socket stats, what is best way to extract data?
I'm considering adding per-socket statistics, starting with number of skbuffs received and number of skbuffs dropped due to no memory.
The actual accounting is fairly straightforward (just add entries to struct sock and increment as appropriate in sock_queue_rcv_skb() and sock_queue_err_skb()), but I'm trying to figure out the best way to make the stats available.
I had considered two possibilities, and it may make sense to use both.
The first would be to expand sock_ioctl() to first check for generic socket commands before calling the protocol specific ioctl() routines. This allows for easy usage from within userspace binaries. The second would be to have socket statistics shown under /proc/<pid>/fd/<fd number>. This would allow for easy script/human access.
Does anyone have any comments about either of these, or about the desirability of this in general?
