From bdaa76c0dbcf6811ae83bbca61ae103e06e93c27 Mon Sep 17 00:00:00 2001 From: Zach Hilman Date: Mon, 29 Oct 2018 16:20:10 -0400 Subject: ns: Implement command 400: GetApplicationControlData Returns the raw NACP bytes and the raw icon bytes into a title-provided buffer. Pulls from Registration Cache for control data, returning all zeros should it not exist. --- src/core/hle/service/filesystem/fsp_srv.cpp | 24 +++++------ src/core/hle/service/ns/ns.cpp | 64 ++++++++++++++++++++++++++++- 2 files changed, 73 insertions(+), 15 deletions(-) (limited to 'src/core/hle/service') diff --git a/src/core/hle/service/filesystem/fsp_srv.cpp b/src/core/hle/service/filesystem/fsp_srv.cpp index 3d1c2ecda..b9a1d5105 100644 --- a/src/core/hle/service/filesystem/fsp_srv.cpp +++ b/src/core/hle/service/filesystem/fsp_srv.cpp @@ -481,9 +481,9 @@ public: // Write the data to memory ctx.WriteBuffer(begin, range_size); - IPC::ResponseBuilder rb{ctx, 4}; + IPC::ResponseBuilder rb{ctx, 3}; rb.Push(RESULT_SUCCESS); - rb.Push(actual_entries); + rb.Push(static_cast(actual_entries)); } private: @@ -498,15 +498,6 @@ private: return Common::swap64(out); } - static std::array ArraySwap(const std::array& in) { - std::array out; - for (std::size_t i = 0; i < in.size(); ++i) { - out[0xF - i] = in[i]; - } - - return out; - } - void FindAllSaves(FileSys::SaveDataSpaceId space) { const auto save_root = OpenSaveDataSpace(space); ASSERT(save_root.Succeeded()); @@ -516,8 +507,9 @@ private: for (const auto& save_id : type->GetSubdirectories()) { for (const auto& user_id : save_id->GetSubdirectories()) { const auto save_id_numeric = stoull_be(save_id->GetName()); - const auto user_id_numeric = - ArraySwap(Common::HexStringToArray<0x10>(user_id->GetName())); + auto user_id_numeric = Common::HexStringToArray<0x10>(user_id->GetName()); + std::reverse(user_id_numeric.begin(), user_id_numeric.end()); + if (save_id_numeric != 0) { // System Save Data info.emplace_back(SaveDataInfo{ @@ -560,12 +552,16 @@ private: for (const auto& title_id : user_id->GetSubdirectories()) { if (!title_id->GetFiles().empty() || !title_id->GetSubdirectories().empty()) { + auto user_id_numeric = + Common::HexStringToArray<0x10>(user_id->GetName()); + std::reverse(user_id_numeric.begin(), user_id_numeric.end()); + info.emplace_back(SaveDataInfo{ 0, space, FileSys::SaveDataType::TemporaryStorage, {}, - Common::HexStringToArray<0x10, true>(user_id->GetName()), + user_id_numeric, stoull_be(type->GetName()), stoull_be(title_id->GetName()), title_id->GetSize(), diff --git a/src/core/hle/service/ns/ns.cpp b/src/core/hle/service/ns/ns.cpp index 07c1381fe..1d2978f24 100644 --- a/src/core/hle/service/ns/ns.cpp +++ b/src/core/hle/service/ns/ns.cpp @@ -2,6 +2,9 @@ // Licensed under GPLv2 or any later version // Refer to the license.txt file included. +#include "common/logging/log.h" +#include "core/file_sys/control_metadata.h" +#include "core/file_sys/patch_manager.h" #include "core/hle/ipc_helpers.h" #include "core/hle/kernel/hle_ipc.h" #include "core/hle/service/ns/ns.h" @@ -118,7 +121,7 @@ public: {305, nullptr, "TerminateSystemApplet"}, {306, nullptr, "LaunchOverlayApplet"}, {307, nullptr, "TerminateOverlayApplet"}, - {400, nullptr, "GetApplicationControlData"}, + {400, &IApplicationManagerInterface::GetApplicationControlData, "GetApplicationControlData"}, {401, nullptr, "InvalidateAllApplicationControlCache"}, {402, nullptr, "RequestDownloadApplicationControlData"}, {403, nullptr, "GetMaxApplicationControlCacheCount"}, @@ -243,6 +246,65 @@ public: RegisterHandlers(functions); } + + void GetApplicationControlData(Kernel::HLERequestContext& ctx) { + IPC::RequestParser rp{ctx}; + const auto flag = rp.PopRaw(); + LOG_DEBUG(Service_NS, "called with flag={:016X}", flag); + + const auto title_id = rp.PopRaw(); + + const auto size = ctx.GetWriteBufferSize(); + + const FileSys::PatchManager pm{title_id}; + const auto control = pm.GetControlMetadata(); + + std::vector out; + + if (control.first != nullptr) { + if (size < 0x4000) { + LOG_ERROR(Service_NS, + "output buffer is too small!
