October 2018 - Linux-stable-mirror

by Ignat Korchagin

Hello, We were trying to build 4.14 kernel with GCC 8, but perf failed to compile. The upstream tree seems to have necessary commits to support GCC 8, but they were not ported to 4.14 branch. With backporting the following commits we were able to restore perf compilation and compile a working 4.14 kernel with GCC 8.2: 6810158d526e483868e519befff407b91e76b3db: perf annotate: Use asprintf when formatting objdump command b7a313d84e853049062011d78cb04b6decd12f5c: perf tools: Fix python extension build for gcc 8 77f18153c080855e1c3fb520ca31a4e61530121d: perf tools: Fix snprint warnings for gcc 8 06c3f2aa9fc68e7f3fe3d83e7569d2a2801d9f99: perf utils: Move is_directory() to path.h Propose to apply the above commits to 4.14 to be able to compile it with GCC 8 (mostly to properly support CONFIG_RETPOLINE) Commit 6810158d526e483868e519befff407b91e76b3db might need adjustment to cleanly apply on 4.14 branch. Regards, Ignat

Backports that remove FPU lazy-mode deadcode (4.4)

Hello Greg, This series contains patches that complete the removal of FPU lazy-mode code, documentation and comments for kernel 4.4.y.

[PATCH stable 4.9 v2 00/29] backport of IP fragmentation fixes

by Florian Fainelli

This is based on Stephen's v4.14 patches, with the necessary merge conflicts, and the lack of timer_setup() on the 4.9 baseline. Perf results on a gigabit capable system, before and after are below.

FAILED: patch "[PATCH] mm: treat indirectly reclaimable memory as free in overcommit" failed to apply to 4.16-stable tree

The patch below does not apply to the 4.16-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From d79f7aa496fc94d763f67b833a1f36f4c171176f Mon Sep 17 00:00:00 2001 From: Roman Gushchin <guro(a)fb.com> Date: Tue, 10 Apr 2018 16:27:47 -0700 Subject: [PATCH] mm: treat indirectly reclaimable memory as free in overcommit logic Indirectly reclaimable memory can consume a significant part of total memory and it's actually reclaimable (it will be released under actual memory pressure). So, the overcommit logic should treat it as free. Otherwise, it's possible to cause random system-wide memory allocation failures by consuming a significant amount of memory by indirectly reclaimable memory, e.g. dentry external names. If overcommit policy GUESS is used, it might be used for denial of service attack under some conditions. The following program illustrates the approach. It causes the kernel to allocate an unreclaimable kmalloc-256 chunk for each stat() call, so that at some point the overcommit logic may start blocking large allocation system-wide. int main() { char buf[256]; unsigned long i; struct stat statbuf; buf[0] = '/'; for (i = 1; i < sizeof(buf); i++) buf[i] = '_'; for (i = 0; 1; i++) { sprintf(&buf[248], "%8lu", i); stat(buf, &statbuf); } return 0; } This patch in combination with related indirectly reclaimable memory patches closes this issue.
