[5.0.0+] RequestGameCardRegistrationStatus/RequestRegisterGameCard removed 8-bytes of input, and now takes an additional type-0x5 input buffer.

[8.0.0+] Cmd76 now takes an additional 0x8-bytes of input.

CreateSystemUpdateTask

Takes an input u32 firmware_variation, an u32 unk, a ContentMetaKey, returns an output #SystemUpdateTask.

Official sw sets unk to: unk = inflag & 1 ? 0xC : 0x4.

DestroySystemUpdateTask

Takes an input #SystemUpdateTask, no output.

ListSystemUpdateTask

Takes a type-0x6 output buffer, for an array of #SystemUpdateTask. Returns a s32 for total output entries.

GetSystemUpdateTaskInfo

Takes an input #SystemUpdateTask, returns an output #SystemUpdateTaskInfo.

CommitSystemUpdateTask

Takes an input #SystemUpdateTask, no output.

GetNetworkInstallTaskInfo

Takes an input #NetworkInstallTask, returns an output #NetworkInstallTaskInfo.

GetDownloadedSystemDataPath

Takes an input u64 titleID, a #SystemUpdateTask, and an type-0x16 output buffer containing the ContentPath.

Gets the FS ContentPath for the specified task and title.

IsExFatDriverIncluded

Takes an input #SystemUpdateTask, returns an output u8 bool flag.

GetApplyDeltaTaskInfo

Takes an input #ApplyDeltaTask, returns an output #ApplyDeltaTaskInfo.

Cmd69

Takes an input u16 port, an u32 Ipv4Address, an u32 firmware_variation, an u32 unk, a ContentMetaKey, returns an output #ReceiveSystemUpdateTask.

Official sw sets unk to: unk = stateflag==0 ? 0x4 : 0xC. The port/Ipv4Address params originate from the RequestReceiveSystemUpdate params.

This is the Receive version of #CreateSystemUpdateTask.

The ContentMetaKey is for the SystemUpdate Meta.

This does state setup, copies ContentMetaKey/firmware_variation/unk into state + more setup, and does socket setup.

Cmd71

Takes a type-0x6 output buffer, for an array of #ReceiveSystemUpdateTask. Returns a s32 for total output entries.

This is the Receive version of #ListSystemUpdateTask.

Cmd72

Takes an input #ReceiveSystemUpdateTask, returns an output Event and an #IAsyncResult.

This is the Receive version of RequestSystemUpdateTaskRun.

This creates the #IAsyncResult object + the async thread which handles the #IAsyncResult operation, which uses the state previously setup by #Cmd69. This throws an error if the object was already created.

Cmd73

Takes an input #ReceiveSystemUpdateTask, returns an output #ReceiveSystemUpdateTaskInfo.

This is the Receive version of #GetSystemUpdateTaskInfo.

Cmd76

Takes an input u16 port, an u32 Ipv4Address, an u32 firmware_variation, and a ContentMetaKey, returns an output #SendSystemUpdateTask.

The port/Ipv4Address params originate from the RequestSendSystemUpdate params.

The ContentMetaKey is for the SystemUpdate Meta (ContentMetaType must match SystemUpdate).

This is the Send version of #Cmd69.

This does state setup, does the above ContentMetaType validation, copies ContentMetaKey/firmware_variation into state, and does socket setup.

Cmd77

Takes an input #SendSystemUpdateTask, returns an output Event and an #IAsyncResult.

This is the Send version of #Cmd72.

This creates the #IAsyncResult object + the async thread which handles the #IAsyncResult operation, which uses the state previously setup by #Cmd76. This throws an error if the object was already created.

Cmd78

Takes an input #SendSystemUpdateTask, returns an output #SendSystemUpdateTaskInfo.

This is the Send version of #Cmd73.

Cmd81

Takes a type-0x6 output buffer, for an array of #SystemUpdateTask. Returns a s32 for total output entries.

This is the Send version of #Cmd71.

Contents Delivery

Content can be transferred with a custom protocol over the network. This is intended for use with local ldn networks, however the used IP addresses can be arbitary. This can be used for SystemUpdates via the above Send/Receive commands (which are then used via ns:su). Application content can also be transferred, which uses a similar (?) protocol.

Task creation for Receive will eventually use the input addr/port with connect(), while the Send version will eventually do the same with bind(). Hence, Receive system = client, while Send system = server.

Messages (requests/replies) begin with the following 0x10-byte header, then any associated data.

Offset Size Description
0x0 0x4 u32 magicnum. Must match 0x7152444c (request messages from the Receive system) or 0x7352444c (reply messages from the Send system). Code validating the magicnum always checks both magicnums, not an individual one.
0x4 0x1 u8 ID. The reply ID must match the request ID.
0x5 0x1 Padding
0x6 0x2 u16 size0. Must be <=0x1000.
0x8 0x8 s64 size1. Must not be negative.

After the header is the associated data for size0 and size1. The functions which generate the header always leave size0 at value 0, when receiving the data for size0 the received data is unused.

The first message used by the client with SystemUpdate is ID 0x1.

With SystemUpdate the server only uses StorageId=NandSystem.

Messages:

ID Request size1 / data Reply size1 / data Description
0x0 0x0 0x0 Tells the server to exit.
0x1 ContentMetaKey 0x38-byte Content Record Gets the Content Record with type==Meta for the specified ContentMetaKey. The SystemUpdate client uses the ContentMetaKey from #Cmd69.
0x2 0x18-bytes: ContentId u8 flag, u8 pad[7]. When flag is 0, during the transfer #SendSystemUpdateTaskInfo SystemUpdateProgress total_size is increased using the size of the current chunk. Once the transfer is finished, the end result is that it would be increased by the total content-size. Size from GetSizeFromContentId with data from ReadContentIdFile. Gets the entire content data for the specified ContentId.
0x3 0x10-byte input for es GetCommonTicketAndCertificateSize/GetCommonTicketAndCertificateData. 0x8-bytes: two size u32s. Then two blocks of data with the sizes specified by the u32s. The server loads the sizes and data from es GetCommonTicketAndCertificateSize/GetCommonTicketAndCertificateData. This is presumably used by the client for Application-Delivery. The two blocks of data are used as the buffers for es ImportTicket by the client.
0x4 s64 current_size 0x0 The input data is copied into the server state, for #SendSystemUpdateTaskInfo SystemUpdateProgress current_size.
