Re: [Tls-reg-review] Registering ALPN for SMB over QUIC

[Vladimir Petter <[e-mail]>]

Thanks Rich,

Here is what we are planning to add to the SMB protocol documentation


           1.9 Standards Assignments
              <skip>

When the SMB 3.1.1 dialect is negotiated, the SMB2 protocol supports QUIC over UDP port 443. ALPN Identification sequence used to identify the SMB2 protocol over QUIC is 0x73 0x6D 0x62 ("smb").

SMB protocol documentation is located here https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-smb2/5606ad47-5ee0-437a-817e-70c366052962<https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Furldefense.com%2Fv3%2F__https%3A%2Fdocs.microsoft.com%2Fen-us%2Fopenspecs%2Fwindows_protocols%2Fms-smb2%2F5606ad47-5ee0-437a-817e-70c366052962__%3B!!GjvTz_vk!A5nBH-_P0FGAo8STpCEFU0hxiscLmJR3_fUrRJIPimK3AfEBG3KfhN4TzXb_%24&data=04%7C01%7Cvpetter%40microsoft.com%7C36c9ed8903ff488b0ec008d8ea347e51%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637516858991598634%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=ZaxJ7znGUnNwvZBibZkTUznbG23DRbwCNaUVwKhYy78%3D&reserved=0>. Clause that I've shared above is work in progress and will be part of the next protocol draft.

Code using this ALPN is already checked in and is ready to be shipped in the future version of Windows client and server. Preliminary information about

ALPN has been shared with our partners that develop their own SMB client and server implementation through materials and talks at conferences.

Please let me know if you need any additional information.

Thanks,
Vladimir.

It's pretty easy.  Just email (reply all) on this thread saying what value you'd like and a pointer to the doc.
The ALPN registry is at https://www.iana.org/assignments/tls-extensiontype-values/tls-extensiontype-values.xhtml#alpn-protocol-ids<https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.iana.org%2Fassignments%2Ftls-extensiontype-values%2Ftls-extensiontype-values.xhtml%23alpn-protocol-ids&data=04%7C01%7Cvpetter%40microsoft.com%7C36c9ed8903ff488b0ec008d8ea347e51%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637516858991588675%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=OTxGatNDBHW4vVushbNucPePQaSHIMtEx%2B1lWPv5nD0%3D&reserved=0>

Hello,

I would apreasiate some guidance on how we should go about registering with IETF an Application Layer Protocol Negotiation (ALPN) that we are using for SMB (Server Message Block protocol; https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-smb2/5606ad47-5ee0-437a-817e-70c366052962<https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Furldefense.com%2Fv3%2F__https%3A%2Fdocs.microsoft.com%2Fen-us%2Fopenspecs%2Fwindows_protocols%2Fms-smb2%2F5606ad47-5ee0-437a-817e-70c366052962__%3B!!GjvTz_vk!A5nBH-_P0FGAo8STpCEFU0hxiscLmJR3_fUrRJIPimK3AfEBG3KfhN4TzXb_%24&data=04%7C01%7Cvpetter%40microsoft.com%7C36c9ed8903ff488b0ec008d8ea347e51%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637516858991598634%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=ZaxJ7znGUnNwvZBibZkTUznbG23DRbwCNaUVwKhYy78%3D&reserved=0>) in our SMB over QUIC implementation (few links below). I was looking at the links on https://www.iana.org/protocols/apply<https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Furldefense.com%2Fv3%2F__https%3A%2Fwww.iana.org%2Fprotocols%2Fapply__%3B!!GjvTz_vk!A5nBH-_P0FGAo8STpCEFU0hxiscLmJR3_fUrRJIPimK3AfEBG3KfhJrkxznf%24&data=04%7C01%7Cvpetter%40microsoft.com%7C36c9ed8903ff488b0ec008d8ea347e51%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637516858991598634%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=JJzEDw70G9tW3fJcgznpZkQCFfZUzCd3tTwlt90mfh4%3D&reserved=0>, and none of them seams to be matching ALPN. Should I use General Protocol Registry Form?
