Passive connections can inherit proper value by cloning, if we make sure all listeners have the proper values there. tcp_disconnect() was setting snd_cwnd to 2, which seems quite obsolete since IW10 adoption. Also remove an obsolete comment. Signed-off-by: Eric Dumazet <edumazet@google.com> --- net/ipv4/tcp.c | 2 +- net/ipv4/tcp_minisocks.c | 8 -------- 2 files changed, 1 insertion(+), 9 deletions(-)
