Are there compelling reasons not to change the socket buffer timeout to a u_long from a u_short? This variable stores the number of ticks before the socket operation times out. At present, the maximum SO_RCVTIMEO or SO_SNDTIMEO value one can set is SHRT_MAX / hz. With a 100Hz kernel, this comes to about 330 seconds, but with a 1000Hz kernel or faster, it's reduced to under 1 minute, which tends to break some apps when running on a high-hz kernel. Particularly for weirdos who use HZ=10000 for dummynet purposes and network measurement, increasing the storage to a u_long would make life a bit happier for all sorts of code that wants to set a 1 minute timeout. -Dave (not on -hackers anymore, please CC) -- work: dga@lcs.mit.edu me: dga@pobox.com MIT Laboratory for Computer Science http://www.angio.net/ I do not accept unsolicited commercial email.
