      net/http/httputil: fix regression in ReverseProxy.ServeHTTP · f93234ad
      Joe Tsai authored 
      In Go1.12 and below, the logic in ReverseProxy.ServeHTTP would always
allocate request.Header even if it were not present in the incoming request.
CL 174324 added http.Request.Clone and re-factors ReverseProxy.ServeHTTP
to use the new Clone method. However, the new Clone logic is not equivalent
to the former logic. We preserve former semantics by explicitly allocating
the Header map if nil.

Fixes #33142

      cmd/cgo: fix check for conversion of ptr to struct field · 84fce983
      Gernot Vormayr authored 
      According to the documentation "When passing a pointer to a field in a
struct, the Go memory in question is the memory occupied by the field,
not the entire struct.". checkAddr states that this should also work
with type conversions, which is implemented in isType. However,
ast.StarExpr must be enclosed in ast.ParenExpr according to the go spec
(see example below), which is not considered in the checks.

Example:
    // struct Si { int i; int *p; }; void f(struct I *x) {}
    import "C"
    type S {
        p *int
        i C.struct_Si
    }
    func main() {
        v := &S{new(int)}
        C.f((*C.struct_I)(&v.i)) // <- panic
    }

This example will cause cgo to emit a cgoCheck that checks the whole
struct S instead of just S.i causing the panic "cgo argument has Go
pointer to Go pointer".

This patch fixes this situation by adding support for ast.ParenExpr to
isType and adds a test, that fails without the fix.

Fixes #32970.

      net/http: fix Transport.MaxConnsPerHost limits & idle pool races · fbaf881c
      Russ Cox authored 
      There were at least three races in the implementation of the pool of
idle HTTP connections before this CL.

The first race is that HTTP/2 connections can be shared for many
requests, but each requesting goroutine would take the connection out
of the pool and then immediately return it before using it; this
created unnecessary, tiny little race windows during which another
goroutine might dial a second connection instead of reusing the first.
This CL changes the idle pool to just leave the HTTP/2 connection in
the pool permanently (until there is reason to close it), instead of
doing the take-it-out-put-it-back dance race.

The second race is that “is there an idle connection?” and
“register to wait for an idle connection” were implemented as two
separate steps, in different critical sections. So a client could end
up registered to wait for an idle connection and be waiting or perhaps
dialing, not having noticed the idle connection sitting in the pool
that arrived between the two steps.

The third race is that t.getIdleConnCh assumes that the inability to
send on the channel means the client doesn't need the result, when it
could mean that the client has not yet entered the select.
That is, the main dial does:

	idleConnCh := t.getIdleConnCh(cm)
	select {
	case v := <-dialc:
		...
	case pc := <-idleConnCh
		...
	...
	}

But then tryPutIdleConn does:

	waitingDialer := t.idleConnCh[key] // what getIdleConnCh(cm) returned
	select {
	case waitingDialer <- pconn:
		// We're done ...
		return nil
	default:
		if waitingDialer != nil {
			// They had populated this, but their dial won
			// first, so we can clean up this map entry.
			delete(t.idleConnCh, key)
		}
	}

If the client has returned from getIdleConnCh but not yet reached the
select, tryPutIdleConn will be unable to do the send, incorrectly
conclude that the client does not care anymore, and put the connection
in the idle pool instead, again leaving the client dialing unnecessarily
while a connection sits in the idle pool.

(It's also odd that the success case does not clean up the map entry,
and also that the map has room for only a single waiting goroutine for
a given host.)

None of these races mattered too much before Go 1.11: at most they
meant that connections were not reused quite as promptly as possible,
or a few more than necessary would be created. But Go 1.11 added
Transport.MaxConnsPerHost, which limited the number of connections
created for a given host. The default is 0 (unlimited), but if a user
did explicitly impose a low limit (2 is common), all these misplaced
conns could easily add up to the entire limit, causing a deadlock.
This was causing intermittent timeouts in TestTransportMaxConnsPerHost.

The addition of the MaxConnsPerHost support added its own races.

For example, here t.incHostConnCount could increment the count
and return a channel ready for receiving, and then the client would
not receive from it nor ever issue the decrement, because the select
need not evaluate these two cases in order:

	select {
	case <-t.incHostConnCount(cmKey):
		// count below conn per host limit; proceed
	case pc := <-t.getIdleConnCh(cm):
		if trace != nil && trace.GotConn != nil {
			trace.GotConn(httptrace.GotConnInfo{Conn: pc.conn, Reused: pc.isReused()})
		}
		return pc, nil
	...
	}

Obviously, unmatched increments are another way to get to a deadlock.
TestTransportMaxConnsPerHost deadlocked approximately 100% of
the time with a small random sleep added between incHostConnCount
and the select:

	ch := t.incHostConnCount(cmKey):
	time.Sleep(time.Duration(rand.Intn(10))*time.Millisecond)
	select {
	case <-ch
		// count below conn per host limit; proceed
	case pc := <-t.getIdleConnCh(cm):
		...
	}

The limit also did not properly apply to HTTP/2, because of the
decrement being attached to the underlying net.Conn.Close
and net/http not having access to the underlying HTTP/2 conn.
The alternate decrements for HTTP/2 may also have introduced
spurious decrements (discussion in #29889). Perhaps those
spurious decrements or other races caused the other intermittent
non-deadlock failures in TestTransportMaxConnsPerHost,
in which the HTTP/2 phase created too many connections (#31982).

This CL replaces the buggy, racy code with new code that is hopefully
neither buggy nor racy.

Fixes #29889.
Fixes #31982.
Fixes #32336.

      cmd/cgo: accept weak dynamic imports · a2fb5cd8
      Austin Clements authored 
      cgo produces dynamic imports for Go binaries by scanning the dynamic
imports table of a binary produced by the system C compiler and
linker. Currently, since it uses elf.File.ImportedSymbols, it only
reads global symbols. Unfortunately, recent versions of lld emit weak
symbol imports for several pthread symbols, which means the cgo tool
doesn't emit dynamic imports for them, which ultimately causes linking
of cgo binaries to fail.

Fix this by using elf.File.DynamicSymbols instead and filtering down
to both global and weak symbols.

Fixes #31912.

      debug/elf: add version information to all dynamic symbols · 7aac3436
      Austin Clements authored 
      Currently, File.ImportedSymbols is the only API that exposes the GNU
symbol version information for dynamic symbols. Unfortunately, it also
filters to specific types of symbols, and only returns symbol names.

The cgo tool is going to need symbol version information for more
symbols. In order to support this and make the API more orthogonal,
this CL adds version information to the Symbol type and updates
File.DynamicSymbols to fill this in. This has the downside of
increasing the size of Symbol, but seems to be the most natural API
for exposing this. I also explored 1) adding a method to get the
version information for the i'th dynamic symbol, but we don't use
symbol indexes anywhere else in the API, and it's not clear if this
index would be 0-based or 1-based, and 2) adding a
DynamicSymbolVersions method that returns a slice of version
information that parallels the DynamicSymbols slice, but that's less
efficient to implement and harder to use.

For #31912.
