  "message": "[release-branch.go1.16] syscall: avoid writing to p when Pipe(p) fails\n\nGenerally speaking Go functions make no guarantees\nabout what has happened to result parameters on error,\nand Pipe is no exception: callers should avoid looking at\np if Pipe returns an error.\n\nHowever, we had a bug in which ForkExec was using the\ncontent of p after a failed Pipe, and others may too.\nAs a robustness fix, make Pipe avoid writing to p on failure.\n\nUpdates #50057\n\nChange-Id: Ie8955025dbd20702fabadc9bbe1d1a5ac0f36305\nReviewed-on: https://team-review.git.corp.google.com/c/golang/go-private/+/1291271\nReviewed-by: Ian Lance Taylor \u003ciant@google.com\u003e\nReviewed-on: https://go-review.googlesource.com/c/go/+/370515\nTrust: Filippo Valsorda \u003cfilippo@golang.org\u003e\nRun-TryBot: Filippo Valsorda \u003cfilippo@golang.org\u003e\nTryBot-Result: Gopher Robot \u003cgobot@golang.org\u003e\nReviewed-by: Alex Rakoczy \u003calex@golang.org\u003e\n",
