[PATCH v3 1/2] s390/kvm: extend kvm_s390_shadow_fault to return entry pointer

by Claudio Imbrenda

Extend kvm_s390_shadow_fault to return the pointer to the valid leaf DAT table entry, or to the invalid entry. Also return some flags in the lower bits of the address: DAT_PROT: indicates that DAT protection applies because of the protection bit in the segment (or, if EDAT, region) tables NOT_PTE: indicates that the address of the DAT table entry returned does not refer to a PTE, but to a segment or region table.

Linux 4.9.256

by Greg Kroah-Hartman

I'm announcing the release of the 4.9.256 kernel. This, and the 4.4.256 release are a little bit "different" than normal. This contains only 1 patch, just the version bump from .255 to .256 which ends up causing the userspace-visable LINUX_VERSION_CODE to behave a bit differently than normal due to the "overflow". With this release, KERNEL_VERSION(4, 9, 256) is the same as KERNEL_VERSION(4, 10, 0). Nothing in the kernel build itself breaks with this change, but given that this is a userspace visible change, and some crazy tools (like glibc and gcc) have logic that checks the kernel version for different reasons, I wanted to do this release as an "empty" release to ensure that everything still works properly. So, this is a YOU MUST UPGRADE requirement of a release. If you rely on the 4.9.y kernel, please throw this release into your test builds and rebuild the world and let us know if anything breaks, or if all is well. Go forth and do full system rebuilds! Yocto and Gentoo are great for this, as will systems that use buildroot. I'll try to hold off on doing a "real" 4.9.y release for a 9eek to give everyone a chance to test this out and get back to me. The pending patches in the 4.9.y queue are pretty serious, so I am loath to wait longer than that, consider yourself warned... The updated 4.9.y git tree can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-4.9.y and can be browsed at the normal kernel.org git web browser: https://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary thanks, greg k-h ------------ Makefile | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) Greg Kroah-Hartman (1): Linux 4.9.256

[PATCH] powerpc/64/signal: Fix regression in __kernel_sigtramp_rt64() semantics

by Raoni Fassina Firmino

Repeated the same tests as the upstream code on top of v5.10.14 and v5.9.16, tested on powerpc64 and powerpc64le, with a glibc build and running the affected glibc's testcase[2], inspected that glibc's backtrace() now gives the correct result and gdb backtrace also keeps working as before. I believe this should be backported to releases 5.9 and 5.10 as userspace is affected in this releases. I hope I had tagged this correctly in the patch. The commit message bellow is cherry-picked from the upstream commit, I am not sure what should I do with the footer, I left it as-is and just added a [rff: Backported] at the end. ---- 8< ---- commit 24321ac668e452a4942598533d267805f291fdc9 upstream. This backport differ from the upstream patch in the way to set the sigtramp offsets, after 5.10 VDSO symbols offsets are retrieved at buildtime and before, in this patch it uses the runtime generated offsets logic. Commit 0138ba5783ae ("powerpc/64/signal: Balance return predictor stack in signal trampoline") changed __kernel_sigtramp_rt64() VDSO and trampoline code, and introduced a regression in the way glibc's backtrace()[1] detects the signal-handler stack frame. Apart from the practical implications, __kernel_sigtramp_rt64() was a VDSO function with the semantics that it is a function you can call from userspace to end a signal handling. Now this semantics are no longer valid. I believe the aforementioned change affects all releases since 5.9. This patch tries to fix both the semantics and practical aspect of __kernel_sigtramp_rt64() returning it to the previous code, whilst keeping the intended behaviour of 0138ba5783ae by adding a new symbol to serve as the jump target from the kernel to the trampoline. Now the trampoline has two parts, a new entry point and the old return point.

Aborted tests ------------- Tests that didn't complete running successfully are marked with ⚡⚡⚡. If this was caused by an infrastructure issue, we try to mark that explicitly in the report. Waived tests ------------ If the test run included waived tests, they are marked with 🚧. Such tests are executed but their results are not taken into account. Tests are waived when their results are not reliable enough, e.g. when they're just introduced or are being fixed. Testing timeout --------------- We aim to provide a report within reasonable timeframe. Tests that haven't finished running yet are marked with ⏱.

patch "staging: gdm724x: Fix DMA from stack" added to staging-testing

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled staging: gdm724x: Fix DMA from stack to my staging git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git in the staging-testing branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will be merged to the staging-next branch sometime soon, after it passes testing, and the merge window is open. If you have any questions about this process, please let me know. >From 7c3a0635cd008eaca9a734dc802709ee0b81cac5 Mon Sep 17 00:00:00 2001 From: Amey Narkhede <ameynarkhede03(a)gmail.com> Date: Thu, 11 Feb 2021 11:08:19 +0530 Subject: staging: gdm724x: Fix DMA from stack Stack allocated buffers cannot be used for DMA on all architectures so allocate hci_packet buffer using kmalloc.
