@ -967,6 +967,21 @@ tcp_tw_reuse - INTEGER
tcp_window_scaling - BOOLEAN
Enable window scaling as defined in RFC1323.
tcp_shrink_window - BOOLEAN
This changes how the TCP receive window is calculated.
RFC 7323, section 2.4, says there are instances when a retracted
window can be offered, and that TCP implementations MUST ensure
that they handle a shrinking window, as specified in RFC 1122.
- 0 - Disabled. The window is never shrunk.
- 1 - Enabled. The window is shrunk when necessary to remain within
the memory limit set by autotuning (sk_rcvbuf).
This only occurs if a non-zero receive window
scaling factor is also in effect.
Default: 0
tcp_wmem - vector of 3 INTEGERs: min, default, max
min: Amount of memory reserved for send buffers for TCP sockets.
Each TCP socket has rights to use it due to fact of its birth.
