Ongoing Short Term Projects

What is the status of D16851? thj@ works on it and you are waiting for feedback from bz@.
rscheff@ is improving AccECN code: D36303.

glebius@ is suggesting to remove the compressed TCP TIMEWAIT state. The memory savings are limited, memory is not that critical anymore and it would simplify the code and allow further optimizations of the code. glebius@ will reach out to people if there are some objections. It was also discussed which information would be need to reduce the time a TCP connections stays in TIMEWAIT state. One thing he will implement is a counter how many compressed states where used at all. Discussion has been started on net@. Reviews: D36398, D36399, D36400. tuexen@ has implemented some packetdrill tests and will review. D36887 improves the memory consumption. It will be kept around if memory consumption is an issue; it is kept around since it would bring back complexity…
glebius@ works on removing INP_DROPPED.
D23230 is implementing ECN++.
D28822 improves PRR, needs some cleanup.
glebius@ wants feedback on D35199. bz@ isn't fine with it…
netstat does not support reading connection information from a core file anymore. tuexen@ will document that in the man-page.
tuexen@ want to write a tool which dumps the BBLog information of a TCP endpoint from a life system or a core. Using kvm_read() has drawbacks as glebius@ pointed out, using a python kgdb script may be an alternative. tuexen@ will think about it.
rscheff@ will add some ECN stat counter to the TCP_INFO option.
