Ian Lance Taylor 7b28fa2c6b reflect: allocate correct type in assignTo and cvtT2I
Backport https://codereview.appspot.com/155450044 from the
master Go library.  Original description:

I came across this while debugging a GC problem in gccgo.
There is code in assignTo and cvtT2I that handles assignment
to all interface values.  It allocates an empty interface even
if the real type is a non-empty interface.  The fields are
then set for a non-empty interface, but the memory is recorded
as holding an empty interface.  This means that the GC has
incorrect information.

This is extremely unlikely to fail, because the code in the GC
that handles empty interfaces looks like this:

obj = nil;
typ = eface->type;
if(typ != nil) {
        if(!(typ->kind&KindDirectIface) || !(typ->kind&KindNoPointers))
                obj = eface->data;

In the current runtime the condition is always true--if
KindDirectIface is set, then KindNoPointers is clear--and we
always want to set obj = eface->data.  So the question is what
happens when we incorrectly store a non-empty interface value
in memory marked as an empty interface.  In that case
eface->type will not be a *rtype as we expect, but will
instead be a pointer to an Itab.  We are going to use this
pointer to look at a *rtype kind field.  The *rtype struct
starts out like this:

type rtype struct {
        size          uintptr
        hash          uint32            // hash of type; avoids computation in hash tables
        _             uint8             // unused/padding
        align         uint8             // alignment of variable with this type
        fieldAlign    uint8             // alignment of struct field with this type
        kind          uint8             // enumeration for C

An Itab always has at least two pointers, so on a
little-endian 64-bit system the kind field will be the high
byte of the second pointer.  This will normally be zero, so
the test of typ->kind will succeed, which is what we want.

On a 32-bit system it might be possible to construct a failing
case by somehow getting the Itab for an interface with one
method to be immediately followed by a word that is all ones.
The effect would be that the test would sometimes fail and the
GC would not mark obj, leading to an invalid dangling
pointer.  I have not tried to construct this test.

I noticed this in gccgo, where this error is much more likely
to cause trouble for a rather random reason: gccgo uses a
different layout of rtype, and in gccgo the kind field happens
to be the low byte of a pointer, not the high byte.

was lost when the Go 1.3 stdlib was merged and changes the FFI path
to call into the same helper code as the amd64/386 path.

I've only tested this on amd64 but I did test a version that was
patched to unconditionally take the FFI path.

Ian Lance Taylor 76deefd0cd runtime: Mark runtime_goexit function as noinline.
If the compiler inlines this function into kickoff, it may reuse
the TLS block address to load g. However, this is not necessarily
correct, as the call to g->entry in kickoff may cause the TLS
address to change. If the wrong value is loaded for g->status in
runtime_goexit, it may cause a runtime panic.

By marking the function as noinline we prevent the compiler from
reusing the TLS address.

Ian Lance Taylor 798c183f7f compiler, runtime: Fix unexpected GC interfering with closure passing.
The Go frontend passes closures through to functions using the
functions __go_set_closure and __go_get_closure.  The
expectation is that there are no function calls between
set_closure and get_closure.  However, it turns out that there
can be function calls if some of the function arguments
require type conversion to an interface type.  Converting to
an interface type can allocate memory, and that can in turn
trigger a garbage collection, and that can in turn call pool
cleanup functions that may call __go_set_closure.  So the
called function can see the wrong closure value, which is bad.

This patch fixes the problem in two different ways.  First, we
move all type conversions in function arguments into temporary
variables so that they can not appear before the call to
__go_set_closure.  (This required shifting the flatten phase
after the simplify_thunk phase, since the latter expects to
work with unconverted argument types.)  Second, we fix the
memory allocation function to preserve the closure value
across any possible garbage collection.

A test case is the libgo database/sql check run with the
environment variable GOGC set to 1.

Ian Lance Taylor dc14e88e07 re PR other/61895 (libbacktrace crashes with bus error with empty file argv[0])
PR other/61895

runtime: Ignore small argv[0] file for backtrace.

Reportedly in some cases Docker starts processes with argv[0]
pointing to an empty file.  That would cause libgo to pass
that empty file to libbacktrace, which would then fail to do
any backtraces.  Everything should work fine if libbacktrace
falls back to /proc/self/exe.

This patch to libgo works around the problem by ignoring
argv[0] if it is a small file, or if stat fails.  This is not
a perfect fix but it's an unusual problem.

This patch changes libgo to look for certain functions that

Ian Lance Taylor d76a1885bd runtime: disable split stacks for runtime_printf function under Clang
LLVM's code generator does not currently support split stacks for vararg
functions, so we disable split stacks for the only function that uses this
feature under Clang. This appears to be OK as long as:
- this function only calls non-inlined, internal-linkage (hence no dynamic
  loader) functions compiled with split stacks (i.e. go_vprintf), which can
  allocate more stack space as required;
- this function itself does not occupy more than BACKOFF bytes of stack space
  (see libgcc/config/i386/morestack.S).
These conditions are currently known to be satisfied by Clang on x86-32 and
x86-64. Note that signal handlers receive slightly less stack space than they
would normally do if they happen to be called while this function is being
run. If this turns out to be a problem we could consider increasing BACKOFF.

The go garbage collector tracks memory in terms of 4kB pages.
Most of the code checks getpagesize() at runtime and does the

On a 64kB ppc64 box I see SEGVs in long running processes
which has been diagnosed as a bug in scavengelist.
scavengelist does a madvise(MADV_DONTNEED) without rounding
the arguments to the system page size.  A strace of one of the
failures shows the problem:

madvise(0xc211030000, 4096, MADV_DONTNEED) = 0

The kernel rounds the length up to 64kB and we mark 60kB of
valid data as no longer needed.

Round start up to a system page and end down before calling
madvise.

Ian Lance Taylor 9c48398f49 runtime: Fix GC bug caused by Entersyscall modifying reg.
This patch fixes a rare but serious bug.  The Go garbage
collector only examines Go stacks.  When Go code calls a
function that is not written in Go, it first calls
syscall.Entersyscall.  Entersyscall records the position of
the Go stack pointer and saves a copy of all the registers.
If the garbage collector runs while the thread is executing
the non-Go code, the garbage collector fetches the stack
pointer and registers from the saved location.

Entersyscall saves the registers using the getcontext
function.  Unfortunately I didn't consider the possibility
that Entersyscall might itself change a register before
calling getcontext.  This only matters for callee-saved
registers, as caller-saved registers would be visible on the
saved stack.  And it only matters if Entersyscall is compiled
to save and modify a callee-saved register before it calls
getcontext.  And it only matters if a garbage collection
occurs while the non-Go code is executing.  And it only
matters if the only copy of a valid Go pointer happens to be
in the callee-saved register when Entersyscall is called.
When all those conditions are true, the Go pointer might get
collected incorrectly, leading to memory corruption.

This patch tries to avoid the problem by splitting
Entersyscall into two functions.  The first is a simple
function that just calls getcontext and then calls the rest of
Entersyscall.  This should fix the problem, provided the
simple Entersyscall function does not itself modify any
callee-saved registers before calling getcontext.  That seems
to be true on the systems I checked.  But since the argument
to getcontext is an offset from a TLS variable, it won't be
true on a system which needs to save callee-saved registers in
order to get the address of a TLS variable.  I don't know why
any system would work that way, but I don't know how to rule
it out.  I think that on any such system this will have to be
implemented in assembler.  I can't put the ucontext_t
structure on the stack, because this function can not split
stacks, and the ucontext_t structure is large enough that it
could cause a stack overflow.

Ian Lance Taylor 91d6f071fb runtime: Use a better heap location on arm64 systems.
Before this, the heap location used on a 64-bit system was not
available to user-space on arm64, so the "32-bit" strategy ended up
being used.  So use somewhere that is available, and for bonus points
is far away from where the kernel allocates address space by default.

Ian Lance Taylor abd471378c runtime: fix 32-bit malloc for pointers >= 0x80000000
The spans array is allocated in runtime_mallocinit.  On a
32-bit system the number of entries in the spans array is
MaxArena32 / PageSize, which (2U << 30) / (1 << 12) == (1 << 19).
So we are allocating an array that can hold 19 bits for an
index that can hold 20 bits.  According to the comment in the
function, this is intentional: we only allocate enough spans
(and bitmaps) for a 2G arena, because allocating more would
probably be wasteful.

But since the span index is simply the upper 20 bits of the
memory address, this scheme only works if memory addresses are
limited to the low 2G of memory.  That would be OK if we were
careful to enforce it, but we're not.  What we are careful to
enforce, in functions like runtime_MHeap_SysAlloc, is that we
always return addresses between the heap's arena_start and
arena_start + MaxArena32.

We generally get away with it because we start allocating just
after the program end, so we only run into trouble with
programs that allocate a lot of memory, enough to get past
address 0x80000000.

This changes the code that computes a span index to subtract
arena_start on 32-bit systems just as we currently do on
64-bit systems.

Ian Lance Taylor f89b66f5ad net: work around Solaris connect issue when server closes socket
On Solaris, if you do a in-progress connect, and then the
server accepts and closes the socket, the client's later
attempt to complete the connect will fail with EINVAL.  Handle
this case by assuming that the connect succeeded.  This code
is weird enough that it is implemented as Solaris-only so that
it doesn't hide a real error on a different OS.

net: use DialTimeout in TestSelfConnect

Backported from master repository.

This avoids problems with systems that take a long time to
find out nothing is listening, while still testing for the
self-connect misfeature since a self-connect should be fast.
With this we may be able to remove the test for non-Linux
systems.

Tested (on GNU/Linux) by editing selfConnect in
tcpsock_posix.go to always return false and verifying that
TestSelfConnect then fails with and without this change.

Ian Lance Taylor 05a7d56678 compiler, runtime: Use runtime functions to pass closure value.
This changes the compiler and runtime to not pass a closure
value as the last argument, but to instead pass it via
__go_set_closure and retrieve it via __go_get_closure.  This
eliminates the need for function descriptor wrapper functions.
It will make it possible to retrieve the closure value in a
reflect.MakeFunc function.

Ian Lance Taylor fdbc38a6e8 compiler, runtime: Use function descriptors.
This changes the representation of a Go value of function type
from being a pointer to function code (like a C function
pointer) to being a pointer to a struct.  The first field of
the struct points to the function code.  The remaining fields,
if any, are the addresses of variables referenced in enclosing
functions.  For each call to a function, the address of the
function descriptor is passed as the last argument.

This lets us avoid generating trampolines, and removes the use
of writable/executable sections of the heap.

The mmap() call which reserves the arena should have MAP_NORESERVE
flag as in typical cases this memory will never be (fully) needed.
This matters in environments which do not do Linux style memory
overcommit, such as OpenIndiana/OpenSolaris/Solaris.

The MAP_NORESERVE flag does not exist on all operating systems
(for example FreeBSD). Therefore we define it to zero value in
case it does not exist.

Before this patch the test would close the file descriptor but
not the os.File.  When the os.File was GC'ed, the finalizer
would close the file descriptor again.  That would cause
problems if the same file descriptor were returned by a later
call to open in another test.
