2022-12-06[release-branch.go1.18] os, net/http: avoid escapes from os.DirFS and ↵Damien Neil
http.Dir on Windows Do not permit access to Windows reserved device names (NUL, COM1, etc.) via os.DirFS and http.Dir filesystems. Avoid escapes from os.DirFS(`\`) on Windows. DirFS would join the the root to the relative path with a path separator, making os.DirFS(`\`).Open(`/foo/bar`) open the path `\\foo\bar`, which is a UNC name. Not only does this not open the intended file, but permits reference to any file on the system rather than only files on the current drive. Make os.DirFS("") invalid, with all file access failing. Previously, a root of "" was interpreted as "/", which is surprising and probably unintentional. Fixes CVE-2022-41720. Fixes #56694.

2022-11-25[release-branch.go1.18] runtime: make GC see object as allocated after it is ↵Cherry Mui
initialized When the GC is scanning some memory (possibly conservatively), finding a pointer, while concurrently another goroutine is allocating an object at the same address as the found pointer, the GC may see the pointer before the object and/or the heap bits are initialized. This may cause the GC to see bad pointers and possibly crash. To prevent this, we make it that the scanner can only see the object as allocated after the object and the heap bits are initialized. Currently the allocator uses freeindex to find the next available slot, and that code is coupled with updating the free index to a new slot past it. The scanner also uses the freeindex to determine if an object is allocated. This is somewhat racy. This CL makes the scanner use a different field, which is only updated after the object initialization (and a memory barrier). Updates #54596. Fixes #56751.

2022-11-09[release-branch.go1.18] runtime: don't jump stack if at entry of systemstackCherry Mui
The traceback code has special "jump stack" logic, to trace back stack switches through systemstack. If we're at the entry of systemstack, the stack switch hasn't happened, so don't jump to user stack. The jump stack logic is only used if we're on the g0 stack. It can happen that we're at the entry of a recursive systemstack call on the g0 stack. In we jump stack here, there will be two problems: 1. There are frames between entering the g0 stack and this recursive systemstack call. Those frames will be lost. 2. Worse, we switched frame.sp but frame.fp calculation will use the entry SP delta (0), which will be wrong, which in turn leads wrong frame.lr and things will go off. For now, don't jump stack if we're at entry of systemstack (SP delta is 0). Using a per-PC SPWRITE marker may be a better fix. If we haven't written the SP, we haven't switched the stack so we can just unwind like a normal function. Updates #55851. Fixes #56635.

-lang=go1.17 and older Prior to Go 1.18, ineffectual //go:linkname directives (i.e., directives referring to an undeclared name, or to a declared type or constant) were treated as noops. In Go 1.18, we changed this into a compiler error to mitigate accidental misuse. However, the x/sys repo contained ineffectual //go:linkname directives up until go.dev/cl/274573, which has caused a lot of user confusion. It seems a bit late to worry about now, but to at least prevent further user pain, this CL changes the error message to only apply to modules using "go 1.18" or newer.

2022-10-24[release-branch.go1.18] runtime: always keep global reference to mp until ↵Michael Pratt
mexit completes Ms are allocated via standard heap allocation (`new(m)`), which means we must keep them alive (i.e., reachable by the GC) until we are completely done using them. Ms are primarily reachable through runtime.allm. However, runtime.mexit drops the M from allm fairly early, long before it is done using the M structure. If that was the last reference to the M, it is now at risk of being freed by the GC and used for some other allocation, leading to memory corruption. Ms with a Go-allocated stack coincidentally already keep a reference to the M in sched.freem, so that the stack can be freed lazily. This reference has the side effect of keeping this Ms reachable. However, Ms with an OS stack skip this and are at risk of corruption. Fix this lifetime by extending sched.freem use to all Ms, with the value of mp.freeWait determining whether the stack needs to be freed or not. For #56243. Fixes #56308.

2022-09-21[release-branch.go1.18] cmd/compile: avoid using destination pointer base ↵Keith Randall
type in memmove optimization The type of the source and destination of a memmove call isn't always accurate. It will always be a pointer (or an unsafe.Pointer), but the base type might not be accurate. This comes about because multiple copies of a pointer with different base types are coalesced into a single value. In the failing example, the IData selector of the input argument is a *[32]byte in one branch of the type switch, and a *[]byte in the other branch.

CalleeEffects issue ir.ClosureExpr implements ir.InitNode, so ir.InitExpr can prepend init statements to it. However, CalleeEffects wasn't aware of this and could cause the init statements to get dropped when inlining a call to a closure. This isn't an issue today, because we don't create closures with init statements. But I ran into this within unified IR. Easy and robust solution: just take advantage that ir.TakeInit can handle any node. Fixes #54918.

2022-08-31[release-branch.go1.18] runtime: mark morestack_noctxt SPWRITE on LR ↵Cherry Mui
architectures On LR architectures, morestack (and morestack_noctxt) are called with a special calling convention, where the caller doesn't save LR on stack but passes it as a register, which morestack will save to g.sched.lr. The stack unwinder currently doesn't understand it, and would fail to unwind from it. morestack already writes SP (as it switches stack), but morestack_noctxt (which tailcalls morestack) doesn't. If a profiling signal lands right in morestack_noctxt, the unwinder will try to unwind the stack and go off, and possibly crash. Marking morestack_noctxt SPWRITE stops the unwinding. Ideally we could teach the unwinder about the special calling convention, or change the calling convention to be less special (so the unwinder doesn't need to fetch a register from the signal context). This is a stop-gap solution, to stop the unwinder from crashing. Updates #54332. Fixes #54674.

2022-08-29[release-branch.go1.18] cmd/go: avoid registering AtExit handlers in testsBryan C. Mills
Ever since 'go build' was added (in CL 5483069), it has used an atexit handler to clean up working directories. CL 154109 introduced 'cc' command to the script test framework that called Init on a builder once per invocation. Unfortunately, since base.AtExit is unsynchronized, the Init added there caused any script that invokes that command to be unsafe for concurrent use. This change fixes the race by having the 'cc' command pass in its working directory instead of allowing the Builder to allocate one. Following modern Go best practices, it also replaces the in-place Init method (which is prone to typestate and aliasing bugs) with a NewBuilder constructor function. Updates #54423. Fixes #54636.

2022-08-29[release-branch.go1.18] cmd/compile: handle partially overlapping assignmentsKeith Randall
Normally, when moving Go values of type T from one location to another, we don't need to worry about partial overlaps. The two Ts must either be in disjoint (nonoverlapping) memory or in exactly the same location. There are 2 cases where this isn't true: 1) Using unsafe you can arrange partial overlaps. 2) Since Go 1.17, you can use a cast from a slice to a ptr-to-array. https://go.dev/ref/spec#Conversions_from_slice_to_array_pointer This feature can be used to construct partial overlaps of array types. var a [3]int p := (*[2]int)(a[:]) q := (*[2]int)(a[1:]) *p = *q We don't care about solving 1. Or at least, we haven't historically and no one has complained. For 2, we need to ensure that if there might be partial overlap, then we can't use OpMove; we must use memmove instead. (memmove handles partial overlap by copying in the correct direction. OpMove does not.) Note that we have to be careful here not to introduce a call when we're marshaling arguments to a call or unmarshaling results from a call.

2022-07-26[release-branch.go1.18] cmd/compile: do not use special literal assignment ↵Cherry Mui
if LHS is address-taken A composite literal assignment x = T{field: v} may be compiled to x = T{} x.field = v We already do not use this form is RHS uses LHS. If LHS is address-taken, RHS may uses LHS implicitly, e.g. v = &x.field x = T{field: *v} The lowering above would change the value of RHS (*v). Updates #52953. Fixes #52961.
