While working w/a user in the IRC channel today, we found a workaround for this
bug, which basically involved increasing a buffer so that it can hold all ip
addresses. Since we can't predict the number of interfaces (they had around
250, default buffer hold 20), I don't like the idea of just making the buffer
really large.
I think there is a logic bug somewhere, because running the agent with
-DmibII/ip reveals that the first loop in var_ipAddrEntry calls getMibstat the
correct number of times, but every subsequent call only looped 19. The code
looks like it tries to deal with having to re-use the buffer for large data
sets, so I'm thinking there is a subtle bug somewhere that limits later calls.
Fixing that bug would be cleaner than simply increasing the buffer.
The IRC user was on a 64 bit machine. Not sure about the original bug
submitter.
If any solaris folks out there could add some dummy virtual interfaces/IPs to
go over the buffer size limit of 20 could verify if the problem exists on 32
bit, that would be helpful.
Any developers on solaris that can try and debug this stuff (in
agent/mibgroup/kernel_solaris.c:getMibstat, called from var_ipAddrEntry) would
be greatly appreciated.
