Hi Jason,

On stable/8 as of the date of this message when attempting the following
configuration the sysctl MIB net.inet.tcp.cc.algorithm is not available
for /etc/sysctl.conf to tune for whatever reason.
/boot/loader.conf:
h_ertt_load="YES"
cc_vegas_load="YES"
/etc/sysctl.conf:
net.inet.tcp.cc.algorithm=vegas
After boot the system still has the congestion algo set to 'newreno'
Does "sysctl net.inet.tcp.cc.available" after boot show only 'newreno'
in the list? Or is 'vegas' listed as well after 'newreno', even though
'newreno' is listed by "sysctl net.inet.tcp.cc.algorithm"?
Only 'newreno'
Ok, definitely a bug then. Should be simple to reproduce, so I'll track
it down and send through a patch for testing when I've got something.
Alright, Ill await the patch for testing.
hmm, I just tested with 8.2-STABLE r225712 in virtualbox with identical
configuration to what you tried and it works for me. System boots with
net.inet.tcp.cc.available as "newreno, vegas" and
net.inet.tcp.cc.algorithm as "vegas".
Anything special about your kernel config? Did you build and install the
modules via "make buildkernel installkernel"? What other kernel modules
do you have loaded?
Cheers,
Lawrence
