1 ================ 2 Design Documents 3 ================ 4 5 This is a list of design documents for Native Client. This list 6 generally covers designs that were implemented. It does not cover 7 PPAPI (Pepper). 8 9 Dynamic loading and linking: 10 11 * `Dynamic loading: Options for supporting dynamic loading, and how they interact with dynamic libraries <http://code.google.com/p/nativeclient/wiki/DynamicLoadingOptions>`_ (2010) 12 13 Handling faults (hardware exceptions) in untrusted code: 14 15 * `NaCl untrusted fault handling: guide to the implementation <https://docs.google.com/a/chromium.org/document/d/1T2KQitbOBz_ALQtr4ONcZcSNCIKNla3DI7t6dMcx5AE/edit>`_ 16 17 Sandbox security on Windows: 18 19 * `Native Client's NTDLL patch on x86-64 Windows <https://src.chromium.org/viewvc/native_client/trunk/src/native_client/documentation/windows_ntdll_patch.txt?revision=HEAD>`_ (2012) 20 21 Debugging using GDB: 22 23 * `Providing a GDB debug stub integrated into native_client <https://docs.google.com/a/chromium.org/document/d/1OtVmgJFC7X7aa57DnyiL4V10vAVax_vcRJp4Mw86lIU/edit>`_ (2012). This was the main design doc for NaCl's GDB debug stub. 24 * `Native Client Support for Debugging, Crash Reporting and Hardware Exception Handling -- high level design <https://docs.google.com/a/google.com/document/d/1tu2FEA4EKhBH669iUgRZBDBcEd6jzNQ-0OVn9JI4_qk/edit>`_ (Jan 2012) 25 * `NaCl: three kinds of crash handling <https://docs.google.com/a/chromium.org/document/d/19qkl5R4lg-AIDf648Ml-gLRq6eZscjvvdMNWkVu2wLk/edit>`_ (2012). This is an earlier document. It contains notes on trusted vs. untrusted crash handling, vs. GDB support. 26 27 PNaCl: 28 29 * `Stability of the PNaCl bitcode ABI <https://docs.google.com/a/google.com/document/d/1xUlWyXnaRnIUBnmKdOBkgq2O9OqfvaRBLaz82pNdKt0/edit>`_ (2013). This is an overview of ABI stability issues and the features of LLVM IR that PNaCl is removing. 30 * `Incrementally simplifying the PNaCl bitcode format <https://docs.google.com/a/chromium.org/document/d/1HvZJVwS9KeTc0jUvoQjbLapRbStHk3mZ0rPDUHNN96Y/edit>`_ (2013) 31 * `SJLJ EH: C++ exception handling in PNaCl using setjmp()+longjmp() <https://docs.google.com/a/chromium.org/document/d/1Bub1bV_IIDZDhdld-zTULE2Sv0KNbOXk33KOW8o0aR4/edit>`_ (2013) 32 33 Security hardening: 34 35 * `Hiding PNaCl's x86-64 sandbox base address <https://docs.google.com/a/chromium.org/document/d/1eskaI4353XdsJQFJLRnZzb_YIESQx4gNRzf31dqXVG8/edit>`_ (2013). This was part of the security hardening we did for enabling PNaCl on the open web. 36 37 MIPS support: 38 39 * `Design for the NaCl MIPS sandbox <https://code.google.com/p/nativeclient/issues/attachmentText?id=2275&aid=22750018000&name=native-client-mips-0.4.txt>`_ (2012) 40 41 Cleanup work: 42 43 * `Removing NaCl's dependency on Chromium <https://docs.google.com/a/chromium.org/document/d/1lycqf4yPMC84011yvuyO_50V8c8COQ8dAe5rNvbeB9o/edit>`_ (2012) 44 45 DEPS rolls: 46 47 * `Semi-automated NaCl DEPS rolls: Updates to nacl_revision field in Chromium's DEPS file <https://docs.google.com/a/chromium.org/document/d/1jHoLo9I3CCS1_-4KlIq1OiEMv9cmMuXES2Z9JVpmPtY/edit>`_ (2013). This is a description of current practice rather than a design doc. 48 49 Obsolete (not implemented) 50 ========================== 51 52 PNaCl multi-threading support: The following proposals do not reflect what was implemented in PNaCl in the end. They are listed here for historical reference. 53 54 * `Multi-threading support for a first release of PNaCl <https://docs.google.com/a/chromium.org/document/d/1HcRiGOaaPLk7pQrGnjXceoM7Px3IwOjjwdiVvJVQNr4/edit>`_ (2013): Proposal for mutex_v2/cond_v2 IRT interfaces. 55 * `Explicit vs. implicit atomicity guarantees in PNaCl <https://docs.google.com/a/chromium.org/document/d/1HcRiGOaaPLk7pQrGnjXceoM7Px3IwOjjwdiVvJVQNr4/edit>`_ (2013): Discussion about how to handle atomic memory operations. 56
