[release-branch.go1.19] syscall, internal/poll: fall back to accept on linux-arm Our minimum Linux version is 2.6.32, and the accept4 system call was introduced in 2.6.28, so we use accept4 everywhere. Unfortunately, it turns out that the accept4 system call was only added to linux-arm in 2.6.36, so for linux-arm only we need to try the accept4 system call and then fall back to accept if it doesn't work. The code we use on linux-arm is the code we used in Go 1.17. On non-arm platforms we continue using the simpler code introduced in Go 1.18. Adding accept4 to the ARM Linux kernel was: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=21d93e2e29722d7832f61cc56d73fb953ee6578e For #57333 Fixes #57339 Change-Id: I6680cb54dd4d3514a6887dda8906e6708c64459d Reviewed-on: https://go-review.googlesource.com/c/go/+/457996 Reviewed-by: David Chase <drchase@google.com> Reviewed-by: Brad Fitzpatrick <bradfitz@golang.org> Reviewed-by: Ian Lance Taylor <iant@google.com> Run-TryBot: Ian Lance Taylor <iant@google.com> Reviewed-by: Than McIntosh <thanm@google.com> Auto-Submit: Ian Lance Taylor <iant@google.com> TryBot-Result: Gopher Robot <gobot@golang.org>
