From mboxrd@z Thu Jan 1 00:00:00 1970 From: will.deacon@arm.com (Will Deacon) Date: Tue, 22 Dec 2015 17:16:12 +0000 Subject: [PATCH] arm64: fix off-by-one in compat syscall table for syscalls over 382 Message-ID: <1450804573-322-1-git-send-email-will.deacon@arm.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org [fix targetting -stable only, no upstream commit required] In the bad old days, our compat syscall table was a linear array defined in assembly code using a series of .quad directives generated from a preprocessed header file. When I added compat support for memfd_create and getrandom in commit a97a42c47608 ("arm64: compat: wire up memfd_create and getrandom syscalls for aarch32"), I forgot to pad the gap where seccomp was due to go, and so the new syscalls actually ended up being off-by-one in the table for v3.17 and v3.18 (in 3.19 seccomp was added and in v4.0 we moved the table construction into C). This patch is intended for -stable trees based on v3.17 or v3.18.
