FreeBSD_HEAD_i386 - Build #1321 - Fixed: Build information: https://jenkins.FreeBSD.org/job/FreeBSD_HEAD_i386/1321/ Full change log: https://jenkins.FreeBSD.org/job/FreeBSD_HEAD_i386/1321/changes Full build log: https://jenkins.FreeBSD.org/job/FreeBSD_HEAD_i386/1321/console Change summaries: 288948 by gjb: Update the last check revision marker. Sponsored by: The FreeBSD Foundation 288947 by gjb: Document r288943, clang, llvm, etc. updated to upstream 3.7.0. Sponsored by: The FreeBSD Foundation 288944 by cem: Fix core corruption caused by race in note_procstat_vmmap This fix is spiritually similar to r287442 and was discovered thanks to the KASSERT added in that revision. NT_PROCSTAT_VMMAP output length, when packing kinfo structs, is tied to the length of filenames corresponding to vnodes in the process' vm map via vn_fullpath. As vnodes may move during coredump, this is racy. We do not remove the race, only prevent it from causing coredump corruption. - Add a sysctl, kern.coredump_pack_vmmapinfo, to allow users to disable kinfo packing for PROCSTAT_VMMAP notes. This avoids VMMAP corruption and truncation, even if names change, at the cost of up to PATH_MAX bytes per mapped object. The new sysctl is documented in core.5. - Fix note_procstat_vmmap to self-limit in the second pass. This addresses corruption, at the cost of sometimes producing a truncated result. - Fix PROCSTAT_VMMAP consumers libutil (and libprocstat, via copy-paste) to grok the new zero padding.

Please note that from 3.5.0 onwards, clang, llvm and lldb require C++11 support to build; see UPDATING for more information. Release notes for llvm and clang can be found here: <http://llvm.org/releases/3.7.0/docs/ReleaseNotes.html>; <http://llvm.org/releases/3.7.0/tools/clang/docs/ReleaseNotes.html>; Thanks to Ed Maste, Andrew Turner and Antoine Brodin for their help.
