From 3fa7ef21b43081a8f40ce76aafdb7cd0695dcda5 Mon Sep 17 00:00:00 2001 From: Mary Date: Thu, 13 Jan 2022 23:29:04 +0100 Subject: [PATCH] ssl: Implement SSL connectivity (#2961) * implement certain servicessl functions * ssl: Implement more of SSL connection and abstract it This adds support to non blocking SSL operations and unlink the SSL implementation from the IPC logic. * Rename SslDefaultSocketConnection to SslManagedSocketConnection * Fix regression on Pokemon TV * Address gdkchan's comment * Simplify value read from previous commit * ssl: some changes - Implement builtin certificates parsing and retrieving - Fix issues with SSL version handling - Improve managed SSL socket error handling - Ensure to only return a certificate on DoHandshake when actually requested * Add missing BuiltInCertificateManager initialization call * Address gdkchan's comment * Address Ack's comment Co-authored-by: InvoxiPlayGames --- .../FileSystem/Content/ContentManager.cs | 2 + .../Services/Ssl/BuiltInCertificateManager.cs | 237 +++++++++ Ryujinx.HLE/HOS/Services/Ssl/ISslService.cs | 79 ++- Ryujinx.HLE/HOS/Services/Ssl/ResultCode.cs | 20 + .../Services/Ssl/SslService/ISslConnection.cs | 458 ++++++++++++++++-- .../Ssl/SslService/ISslConnectionBase.cs | 25 + .../Services/Ssl/SslService/ISslContext.cs | 11 +- .../SslService/SslManagedSocketConnection.cs | 247 ++++++++++ .../Ssl/Types/BuiltInCertificateInfo.cs | 10 + .../HOS/Services/Ssl/Types/CaCertificateId.cs | 68 +++ .../HOS/Services/Ssl/Types/SslVersion.cs | 3 +- .../Services/Ssl/Types/TrustedCertStatus.cs | 12 + 12 files changed, 1138 insertions(+), 34 deletions(-) create mode 100644 Ryujinx.HLE/HOS/Services/Ssl/BuiltInCertificateManager.cs create mode 100644 Ryujinx.HLE/HOS/Services/Ssl/ResultCode.cs create mode 100644 Ryujinx.HLE/HOS/Services/Ssl/SslService/ISslConnectionBase.cs create mode 100644 Ryujinx.HLE/HOS/Services/Ssl/SslService/SslManagedSocketConnection.cs create mode 100644 Ryujinx.HLE/HOS/Services/Ssl/Types/BuiltInCertificateInfo.cs create mode 100644 Ryujinx.HLE/HOS/Services/Ssl/Types/CaCertificateId.cs create mode 100644 Ryujinx.HLE/HOS/Services/Ssl/Types/TrustedCertStatus.cs diff --git a/Ryujinx.HLE/FileSystem/Content/ContentManager.cs b/Ryujinx.HLE/FileSystem/Content/ContentManager.cs index dbc18d85..9203f156 100644 --- a/Ryujinx.HLE/FileSystem/Content/ContentManager.cs +++ b/Ryujinx.HLE/FileSystem/Content/ContentManager.cs @@ -10,6 +10,7 @@ using LibHac.Tools.FsSystem.NcaUtils; using LibHac.Tools.Ncm; using Ryujinx.Common.Logging; using Ryujinx.HLE.Exceptions; +using Ryujinx.HLE.HOS.Services.Ssl; using Ryujinx.HLE.HOS.Services.Time; using Ryujinx.HLE.Utilities; using System; @@ -195,6 +196,7 @@ namespace Ryujinx.HLE.FileSystem.Content if (device != null) { TimeManager.Instance.InitializeTimeZone(device); + BuiltInCertificateManager.Instance.Initialize(device); device.System.SharedFontManager.Initialize(); } } diff --git a/Ryujinx.HLE/HOS/Services/Ssl/BuiltInCertificateManager.cs b/Ryujinx.HLE/HOS/Services/Ssl/BuiltInCertificateManager.cs new file mode 100644 index 00000000..b585224d --- /dev/null +++ b/Ryujinx.HLE/HOS/Services/Ssl/BuiltInCertificateManager.cs @@ -0,0 +1,237 @@ +using LibHac; +using LibHac.Common; +using LibHac.Fs; +using LibHac.Fs.Fsa; +using LibHac.FsSystem; +using LibHac.Tools.FsSystem; +using LibHac.Tools.FsSystem.NcaUtils; +using Ryujinx.Common.Configuration; +using Ryujinx.Common.Logging; +using Ryujinx.HLE.Exceptions; +using Ryujinx.HLE.FileSystem; +using Ryujinx.HLE.FileSystem.Content; +using Ryujinx.HLE.HOS.Services.Ssl.Types; +using System; +using System.Collections.Generic; +using System.IO; +using System.Runtime.CompilerServices; +using System.Runtime.InteropServices; + +namespace Ryujinx.HLE.HOS.Services.Ssl +{ + class BuiltInCertificateManager + { + private const long CertStoreTitleId = 0x0100000000000800; + + private readonly string CertStoreTitleMissingErrorMessage = "CertStore system title not found!
