From 75a7c5e2d1f09a4a58e7e1f1f4ef0b0f55a33413 Mon Sep 17 00:00:00 2001 From: Dmitry Vyukov Date: Mon, 19 Feb 2018 19:35:04 +0100 Subject: prog: rework address allocation 1. mmap all memory always, without explicit mmap calls in the program. This makes lots of things much easier and removes lots of code. Makes mmap not a special syscall and allows to fuzz without mmap enabled. 2. Change address assignment algorithm. Current algorithm allocates unmapped addresses too frequently and allows collisions between arguments of a single syscall. The new algorithm analyzes actual allocations in the program and places new arguments at unused locations. --- prog/hints_test.go | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'prog/hints_test.go') diff --git a/prog/hints_test.go b/prog/hints_test.go index 9a87d3014..a3fd94c62 100644 --- a/prog/hints_test.go +++ b/prog/hints_test.go @@ -421,7 +421,7 @@ func TestHintsData(t *testing.T) { Target: target, Calls: []*Call{{ Meta: call, - Args: []Arg{MakePointerArg(call.Args[0], 0, 0, 0, + Args: []Arg{MakePointerArg(call.Args[0], 0, MakeDataArg(call.Args[0].(*PtrType).Type, input))}, Ret: MakeReturnArg(call.Ret), }}, -- cgit mrf-deployment
