This algorithm does nothing except initializing the congestion control window
to a fixed value. Very smart!
Modify the QUIC congestion control configuration parser to support this new
algorithm. The congestion control algorithm must be set as follows:
quic-cc-algo nocc-<cc window size(KB))
For instance if "nocc-15" is provided as quic-cc-algo keyword value, this
will set a fixed window of 15KB.
Define a new configuration option "tune.quic.max-frame-loss". This is
used to specify the limit for which a single frame instance can be
detected as lost. If exceeded, the connection is closed.
This should be backported up to 2.7.
Define global configuration option "tune.quic.socket-owner". This option
can be used to activate or not socket per QUIC connection mode. The
default value is "listener" which disable this feature. It can be
activated with the option "connection".
This change is part of quic-conn owned socket implementation.
It may be backported to 2.7 after a period of observation.
cfgparse-quic accesses some members of the "global" struct but only
includes global-t.h. It actually used to work via tools.h due to a
long dependency chain that brought it, but it will be fixed and will
break cfgparse-quic, so let's fix it first.
As it could be interesting to be able to choose the QUIC control congestion
algorithm to be used by listener, add "quic-cc-algo" new keyword to do so.
Update the documentation consequently.
Must be backported to 2.6.
Rename "tune.quic.conn-buf-limit" to "tune.quic.frontend.conn-tx-buffers.limit"
to reflect the stream direction (TX) and the objects (frontends) which are
concerned.
Add tunable "tune.quic.frontend.max_streams_bidi" setting for QUIC frontends
to set the "initial_max_streams_bidi" transport parameter.
Add some documentation for this new setting.
Add two tunable settings both for backends and frontends "max_idle_timeout"
QUIC transport parameter, "tune.quic.frontend.max-idle-timeout" and
"tune.quic.backend.max-idle-timeout" respectively.
cfg_parse_quic_time() has been implemented to parse a time value thanks
to parse_time_err(). It should be reused for any tunable time value to be
parsed.
Add the documentation for this tunable setting only for frontend.
This QUIC specific keyword may be used to set the theshold, in number of
connection openings, beyond which QUIC Retry feature will be automatically
enabled. Its default value is 100.
Implement the emission of Retry packets. These packets are emitted in
response to Initial from clients without token. The token from the Retry
packet contains the ODCID from the Initial packet.
By default, Retry packet emission is disabled and the handshake can
continue without address validation. To enable Retry, a new bind option
has been defined named "quic-force-retry". If set, the handshake must be
conducted only after receiving a token in the Initial packet.
