[snowflake/master] Bump version of pion/sdp
by cohosh＠torproject.org 25 Jan '21

commit 1b29ad7de14fb0a6d2bf88aea38353733682cd26 Author: Cecylia Bocovich <cohosh(a)torproject.org> Date: Mon Jan 25 10:28:17 2021 -0500 Bump version of pion/sdp Update our dependency on pion/sdp from v2 to v3, to match pion/webrtc v3. This requires some changes in how we parse out addresses from ice candidates. This will ease tor browser builds of snowflake since we are now only relying on one version of pion/sdp instead of two different ones. --- common/util/util.go | 9 +++++---- go.mod | 3 ++- go.sum | 2 -- proxy/snowflake.go | 7 ++++--- 4 files changed, 11 insertions(+), 10 deletions(-) diff --git a/common/util/util.go b/common/util/util.go index 3d2acc3..00f7302 100644 --- a/common/util/util.go +++ b/common/util/util.go @@ -5,7 +5,8 @@ import ( "errors" "net" - "github.com/pion/sdp/v2" + "github.com/pion/ice/v2" + "github.com/pion/sdp/v3" "github.com/pion/webrtc/v3" ) @@ -77,9 +78,9 @@ func StripLocalAddresses(str string) string { attrs := make([]sdp.Attribute, 0) for _, a := range m.Attributes { if a.IsICECandidate() { - ice, err := a.ToICECandidate() - if err == nil && ice.Typ == "host" { - ip := net.ParseIP(ice.Address) + c, err := ice.UnmarshalCandidate(a.Value) + if err == nil && c.Type() == ice.CandidateTypeHost { + ip := net.ParseIP(c.Address()) if ip != nil && (IsLocal(ip) || ip.IsUnspecified() || ip.IsLoopback()) { /* no append in this case */ continue diff --git a/go.mod b/go.mod index 2931be7..a7f9ad2 100644 --- a/go.mod +++ b/go.mod @@ -5,7 +5,8 @@ go 1.13 require ( git.torproject.org/pluggable-transports/goptlib.git v1.1.0 github.com/gorilla/websocket v1.4.1 - github.com/pion/sdp/v2 v2.3.4 + github.com/pion/ice/v2 v2.0.14 + github.com/pion/sdp/v3 v3.0.3 github.com/pion/stun v0.3.5 github.com/pion/webrtc/v3 v3.0.0 github.com/smartystreets/goconvey v1.6.4 diff --git a/go.sum b/go.sum index 6214f5c..eac95e1 100644 --- a/go.sum +++ b/go.sum @@ -66,8 +66,6 @@ github.com/pion/rtp v1.6.2/go.mod h1:bDb5n+BFZxXx0Ea7E5qe+klMuqiBrP+w8XSjiWtCUko github.com/pion/sctp v1.7.10/go.mod h1:EhpTUQu1/lcK3xI+eriS6/96fWetHGCvBi9MSsnaBN0= github.com/pion/sctp v1.7.11 h1:UCnj7MsobLKLuP/Hh+JMiI/6W5Bs/VF45lWKgHFjSIE= github.com/pion/sctp v1.7.11/go.mod h1:EhpTUQu1/lcK3xI+eriS6/96fWetHGCvBi9MSsnaBN0= -github.com/pion/sdp/v2 v2.3.4 h1:+f3F5Xl7ynVhc9Il8Dc7BFroYJWG3PMbfWtwFlVI+kg= -github.com/pion/sdp/v2 v2.3.4/go.mod h1:jccXVYW0fuK6ds2pwKr89SVBDYlCjhgMI6nucl5R5rA= github.com/pion/sdp/v3 v3.0.3 h1:gJK9hk+JFD2NGIM1nXmqNCq1DkVaIZ9dlA3u3otnkaw= github.com/pion/sdp/v3 v3.0.3/go.mod h1:bNiSknmJE0HYBprTHXKPQ3+JjacTv5uap92ueJZKsRk= github.com/pion/srtp/v2 v2.0.0-rc.3 h1:1fPiK1nJlNyh235tSGgBnXrPc99wK1/D707f6ntb3qY= diff --git a/proxy/snowflake.go b/proxy/snowflake.go index 78a053d..1bc21ab 100644 --- a/proxy/snowflake.go +++ b/proxy/snowflake.go @@ -23,7 +23,8 @@ import ( "git.torproject.org/pluggable-transports/snowflake.git/common/util" "git.torproject.org/pluggable-transports/snowflake.git/common/websocketconn" "github.com/gorilla/websocket" - "github.com/pion/sdp/v2" + "github.com/pion/ice/v2" + "github.com/pion/sdp/v3" "github.com/pion/webrtc/v3" ) @@ -83,9 +84,9 @@ func remoteIPFromSDP(str string) net.IP { for _, m := range desc.MediaDescriptions { for _, a := range m.Attributes { if a.IsICECandidate() { - ice, err := a.ToICECandidate() + c, err := ice.UnmarshalCandidate(a.Value) if err == nil { - ip := net.ParseIP(ice.Address) + ip := net.ParseIP(c.Address()) if ip != nil && isRemoteAddress(ip) { return ip }

[sbws/maint-1.1] chg: generate, cleanup: Use 28 days of measurements
by juga＠torproject.org 25 Jan '21

commit e416547c73d166bd085a10843c6ba4d1a4167092 Author: juga0 <juga(a)riseup.net> Date: Sat Jan 23 09:54:19 2021 +0000 chg: generate, cleanup: Use 28 days of measurements When generating the Bandwidth File as Torflow, use 28 days of past raw measurements instead of 5, by default.
