by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled crypto: x86/twofish-3way - Fix %rbp usage to the 3.18-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: crypto-x86-twofish-3way-fix-rbp-usage.patch and it can be found in the queue-3.18 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From d8c7fe9f2a486a6e5f0d5229ca43807af5ab22c6 Mon Sep 17 00:00:00 2001 From: Eric Biggers <ebiggers(a)google.com> Date: Mon, 18 Dec 2017 16:40:26 -0800 Subject: crypto: x86/twofish-3way - Fix %rbp usage From: Eric Biggers <ebiggers(a)google.com> commit d8c7fe9f2a486a6e5f0d5229ca43807af5ab22c6 upstream. Using %rbp as a temporary register breaks frame pointer convention and breaks stack traces when unwinding from an interrupt in the crypto code. In twofish-3way, we can't simply replace %rbp with another register because there are none available. Instead, we use the stack to hold the values that %rbp, %r11, and %r12 were holding previously. Each of these values represents the half of the output from the previous Feistel round that is being passed on unchanged to the following round. They are only used once per round, when they are exchanged with %rax, %rbx, and %rcx. As a result, we free up 3 registers (one per block) and can reassign them so that %rbp is not used, and additionally %r14 and %r15 are not used so they do not need to be saved/restored. There may be a small overhead caused by replacing 'xchg REG, REG' with the needed sequence 'mov MEM, REG; mov REG, MEM; mov REG, REG' once per round. But, counterintuitively, when I tested "ctr-twofish-3way" on a Haswell processor, the new version was actually about 2% faster. (Perhaps 'xchg' is not as well optimized as plain moves.)

[PATCH] ARM: orion: fix orion_ge00_switch_board_info initialization

by Arnd Bergmann

A section type mismatch warning shows up when building with LTO, since orion_ge00_mvmdio_bus_name was put in __initconst but not marked const itself: include/linux/of.h: In function 'spear_setup_of_timer': arch/arm/mach-spear/time.c:207:34: error: 'timer_of_match' causes a section type conflict with 'orion_ge00_mvmdio_bus_name' static const struct of_device_id timer_of_match[] __initconst = { ^ arch/arm/plat-orion/common.c:475:32: note: 'orion_ge00_mvmdio_bus_name' was declared here static __initconst const char *orion_ge00_mvmdio_bus_name = "orion-mii"; ^ As pointed out by Andrew Lunn, it should in fact be 'const' but not '__initconst' because the string is never copied but may be accessed after the init sections are freed. To fix that, I get rid of the extra symbol and rewrite the initialization in a simpler way that assigns both the bus_id and modalias statically. I spotted another theoretical bug in the same place, where d->netdev[i] may be an out of bounds access, this can be fixed by moving the device assignment into the loop.

[PATCH] ipv6 sit: work around bogus gcc-8 -Wrestrict warning

by Arnd Bergmann

gcc-8 has a new warning that detects overlapping input and output arguments in memcpy(). It triggers for sit_init_net() calling ipip6_tunnel_clone_6rd(), which is actually correct: net/ipv6/sit.c: In function 'sit_init_net': net/ipv6/sit.c:192:3: error: 'memcpy' source argument is the same as destination [-Werror=restrict] The problem here is that the logic detecting the memcpy() arguments finds them to be the same, but the conditional that tests for the input and output of ipip6_tunnel_clone_6rd() to be identical is not a compile-time constant. We know that netdev_priv(t->dev) is the same as t for a tunnel device, and comparing "dev" directly here lets the compiler figure out as well that 'dev == sitn->fb_tunnel_dev' when called from sit_init_net(), so it no longer warns. This code is old, so Cc stable to make sure that we don't get the warning for older kernels built with new gcc.
