patch "usb: usbmon: Read text within supplied buffer size" added to usb-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled usb: usbmon: Read text within supplied buffer size to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus 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 hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From a5f596830e27e15f7a0ecd6be55e433d776986d8 Mon Sep 17 00:00:00 2001 From: Pete Zaitcev <zaitcev(a)kotori.zaitcev.us> Date: Fri, 9 Mar 2018 00:21:14 -0600 Subject: usb: usbmon: Read text within supplied buffer size This change fixes buffer overflows and silent data corruption with the usbmon device driver text file read operations.

[stable-4.14/4.15] KVM: x86: fix backward migration with async_PF

by Jack Wang

From: Radim Krčmář <rkrcmar(a)redhat.com> commit fe2a3027e74e40a3ece3a4c1e4e51403090a907a upstream. Guests on new hypersiors might set KVM_ASYNC_PF_DELIVERY_AS_PF_VMEXIT bit when enabling async_PF, but this bit is reserved on old hypervisors, which results in a failure upon migration. To avoid breaking different cases, we are checking for CPUID feature bit before enabling the feature and nothing else.

[PATCH 37/39] arm/arm64: smccc: Make function identifiers an unsigned quantity

by Alex Shi

From: Marc Zyngier <marc.zyngier(a)arm.com> commit ded4c39e93f3 upstream. Function identifiers are a 32bit, unsigned quantity. But we never tell so to the compiler, resulting in the following: 4ac: b26187e0 mov x0, #0xffffffff80000001 We thus rely on the firmware narrowing it for us, which is not always a reasonable expectation.

[PATCH 22/39] arm64: KVM: Increment PC after handling an SMC trap

by Alex Shi

From: Marc Zyngier <marc.zyngier(a)arm.com> commit f5115e8869e1 upstream. When handling an SMC trap, the "preferred return address" is set to that of the SMC, and not the next PC (which is a departure from the behaviour of an SMC that isn't trapped).

[PATCH] Revert "nvme: create 'slaves' and 'holders' entries for hidden controllers"

by Christoph Hellwig

This reverts commit e9a48034d7d1318ece7d4a235838a86c94db9d68. The slaves and holders link for the hidden gendisks confuse lsblk so that it errors out on, or doesn't report the nvme multipath devices. Given that we don't need holder relationships for something that can't even be directly accessed we should just stop creating those links.

The following changes since commit 3f986eefc89c528bf2d398a6dc3637b743a7139e: Merge branch 'perf/urgent' into perf/core, to resolve conflict (2018-03-07 09:23:12 +0100) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git tags/perf-core-for-mingo-4.17-20180308 for you to fetch changes up to 2427b432e63b4b911100f717c48289195b7a7d62: perf tools: Update quipper information (2018-03-08 11:30:54 -0300) ---------------------------------------------------------------- perf/core improvements and fixes: - Support to display the IPC/Cycle in 'annotate' TUI, for systems where this info can be obtained, like Intel's >= Skylake (Jin Yao) - Support wildcards on PMU name in dynamic PMU events (Agustin Vega-Frias) - Display pmu name when printing unmerged events in stat (Agustin Vega-Frias) - Auto-merge PMU events created by prefix or glob match (Agustin Vega-Frias) - Fix s390 'call' operations target function annotation (Thomas Richter) - Handle s390 PC relative load and store instruction in the augmented 'annotate', code, used so far in the TUI modes of 'perf report' and 'perf annotate' (Thomas Richter) - Provide libtraceevent with a kernel symbol resolver, so that symbols in tracepoint fields can be resolved when showing them in tools such as 'perf report' (Wang YanQing) - Refactor the cgroups code to look more like other code in tools/perf, using cgroup__{put,get} for refcount operations instead of its open-coded equivalent, breaking larger functions, etc (Arnaldo Carvalho de Melo) - Implement support for the -G/--cgroup target in 'perf trace', allowing strace like tracing (plus other events, backtraces, etc) for cgroups (Arnaldo Carvalho de Melo) - Update thread shortname in 'perf sched map' when the thread's COMM changes (Changbin Du) - refcount 'struct mem_info', for better sharing it over several users, avoid duplicating structs and fixing crashes related to use after free (Jiri Olsa) - Display perf.data version, offsets in 'perf report --header' (Jiri Olsa) - Record the machine's memory topology information in a perf.data feature section, to be used by tools such as 'perf c2c' (Jiri Olsa) - Fix output of forced groups in the header for 'perf report' --stdio and --tui (Jiri Olsa) - Better support llvm, clang, cxx make tests in the build process (Jiri Olsa) - Streamline the 'struct perf_mmap' methods, storing some info in the struct instead of passing it via various methods, shortening its signatures (Kan Liang) -

Where clang is available, it is also used to build perf with/without libelf. The objtool and samples/bpf/ builds are disabled now that I'm switching from using the sources in a local volume to fetching them from a http server to build it inside the container, to make it easier to build in a container cluster. Those will come back later. Several are cross builds, the ones with -x-ARCH and the android one, and those may not have all the features built, due to lack of multi-arch devel packages, available and being used so far on just a few, like debian:experimental-x-{arm64,mipsel}. The 'perf test' one will perform a variety of tests exercising tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands with a variety of command line event specifications to then intercept the sys_perf_event syscall to check that the perf_event_attr fields are set up as expected, among a variety of other unit tests. Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/ with a variety of feature sets, exercising the build with an incomplete set of features as well as with a complete one. It is planned to have it run on each of the containers mentioned above, using some container orchestration infrastructure.
