  "message": "Fuchsia: Turn safeside ret2spec tests into a library\n\nret2spec is a class of Spectre V2-related speculative execution\ninformation leaks, where the contents of return address stacks are\npoisoned. Poisoned return address stacks can be used to cause\nsensitive code to (speculatively) execute attacker-controlled\ncode, which can be used as a building block in infoleak attacks.\n\nRet2spec attacks can be carried out within a process, across\nuser/kernel boundaries on a CPU, and across processes.\n\nSafeside is a collection of demos of speculative execution\nattacks, including ret2spec; we plan to use its demos to test\nFuchsia\u0027s speculative execution mitigations.\n\nConvert Safeside\u0027s standalone ret2spec demos into a library,\nso that Fuchsia-driven tests can use them. We do not have a\ntest in-tree of ret2spec_ca (cross-address-space), but will adapt\nret2spec_sa into one.\n\nBug: 12540 Speculative Execution Mitigations.\nBug: 33667 Spectre mitigations?\n\nChange-Id: I239a8ba1f1b73f6ef58b6baa2b1f54ac6f3c3cb3\n",
