Hi,
Something weird is happening in -current. I installed world, a
kernel and bootblocks on Jan 6 - I can't say for sure that it wasn't
happening before this as I usually do all ppp testing via the
loopback interface on a single machine for convenience.
Yesterday, I tried using ppp on the above -current via a tty and got
two weird results, both happen at random intervals, but are
reasonably easy to reproduce.
1. I select() on a tty descriptor for reading (and writing &
exceptions). Select comes back with the read descriptor set,
I do a read() and get -1 with errno EAGAIN. This must be
wrong !
2. I select() on a tty descriptor for reading, writing and
exceptions and get the exception fd_set bit set. This has never
happened before, and it was only a few weeks ago that I even had
ppp not always abend when an exception is detected.
Does anybody know what's going on (before I look into things further) ?
Help would be appreciated if anyone has any su{spicions,gestions}.
Cheers.
