+From: "Jason A. Donenfeld" <Jason@zx2c4.com>
+Date: Wed, 23 Oct 2019 13:08:46 +0200
+Subject: [PATCH] [release-branch.go1.13] syscall: reenable sysctl on iOS
+
+This was disabled due to a report that the App Store rejects the symbol
+__sysctl. However, we use the sysctl symbol, which is fine. The __sysctl
+symbol is used by x/sys/unix, which needs fixing instead. So, this
+commit reenables sysctl on iOS, so that things like net.InterfaceByName
+can work again.
+
+This reverts CL 193843, CL 193844, CL 193845, and CL 193846.
+
+Fixes #35105
+Updates #35101
+Updates #34133
+Updates #35103
