[Linux-stable-mirror] [PATCH] PCI: keystone: fix interrupt-controller-node lookup

by Johan Hovold

Fix child-node lookup during initialisation, which ended up searching the whole device tree depth-first starting at the parent rather than just matching on its children. To make things worse, the parent pci node was prematurely freed, while the child interrupt-controller node was leaked.

As I already handled that in the merge of the second patch, the first one is not needed, and the end result should be the same. So all is good. Or at least I think so, someone verifying I got this all right would be appreciated :) thanks, greg k-h

I think it would be useful if there was some metadata in the commit message which identified that it was selected through some automated system. That way if I find a regression and it identifies one of these commits I can know that maybe it was chosen incorrectly, and also would allow me to alert the owner of the selection script to better help refine its selection process. Otherwise I'd have to track back through the mailing lists to see how it landed in the stable release. Just a thought. Also, thank you for trying to improve the stable kernels! -- Josh

Re: [Linux-stable-mirror] 4.1 EOL

by alexander.levin＠verizon.com

I've cc'ed some folks in hopes to get this resolved upstream. Either way, 4.1's EoL was previously moved to about 6 months from now, so hopefully we'll have more than enough time to get this resolved.

[Linux-stable-mirror] [PATCH V10 4/4] libsas: Align sata_device's rps_resp on a cacheline

by Huacai Chen

The rps_resp buffer in ata_device is a DMA target, but it isn't explicitly cacheline aligned. Due to this, adjacent fields can be overwritten with stale data from memory on non-coherent architectures. As a result, the kernel is sometimes unable to communicate with an SATA device behind a SAS expander. Fix this by ensuring that the rps_resp buffer is cacheline aligned. This issue is similar to that fixed by Commit 84bda12af31f93 ("libata: align ap->sector_buf") and Commit 4ee34ea3a12396f35b26 ("libata: Align ata_device's id on a cacheline").

[Linux-stable-mirror] [PATCH 7.x ubsan fix 1/6] cputime: Prevent 32bit overflow in time[val|spec]_to_cputime()

by Kefeng Wang

From: zengtao <prime.zeng(a)huawei.com> mainline inclusion from mainline-4.5 commit 0f26922fe5dc5724b1adbbd54b21bad03590b4f3 category: bugfix bugzilla: 3214 DTS: NA CVE: NA ------------------------------------------------- The datatype __kernel_time_t is u32 on 32bit platform, so its subject to overflows in the timeval/timespec to cputime conversion. Currently the following functions are affected: 1. setitimer() 2. timer_create/timer_settime() 3. sys_clock_nanosleep This can happen on MIPS32 and ARM32 with "Full dynticks CPU time accounting" enabled, which is required for CONFIG_NO_HZ_FULL. Enforce u64 conversion to prevent the overflow.
