* rtld-elf: link udivmoddi4 from compiler_rtRyan Libby2020-12-191-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | This fixes the gcc9 build of rtld-elf32 on amd64, which needed an implementation of udivmoddi4. rtld-elf uses certain functions normally found in libc, and so it includes certain files from libc in its own build. It has two mechanisms to include files from libc: one that rebuilds source files in the rtld-elf environment, and one that extracts object files from a purpose-built no-SSP PIC archive. In addition to libc functions, rtld-elf may need to link functions normally found in libcompiler_rt (formerly libgcc). Now, add an ability to rebuild libcompiler_rt source files in the rtld-elf environment. We don't yet have a need for an object file extraction mechanism. libcompiler_rt could also supply udivdi3 and umoddi3, but leave them alone for now.

* kern: cpuset: allow jails to modify child jails' rootsKyle Evans2020-12-191-5/+20
| | | | | | | | | | | | | | | | | | | | | | | This partially lifts a restriction imposed by r191639 ("Prevent a superuser inside a jail from modifying the dedicated root cpuset of that jail") that's perhaps beneficial after r192895 ("Add hierarchical jails."). Jails still cannot modify their own cpuset, but they can modify child jails' roots to further restrict them or widen them back to the modifying jails' own mask. As a side effect of this, the system root may once again widen the mask of jails as long as they're still using a subset of the parent jails' mask. This was previously prevented by the fact that cpuset_getroot of a root set will return that root, rather than the root's parent -- cpuset_modify uses cpuset_getroot since it was introduced in r327895, previously it was just validating against set->cs_parent which allowed the system root to widen jail masks.

* Switch direct rt fields access in rtsock.c to newly-create field acessors.Alexander V. Chernikov2020-12-181-38/+121
| | | | | | | | | | | | | | | | | | rtsock code was build around the assumption that each rtentry record in the system radix tree is a ready-to-use sockaddr. This assumptions turned out to be not quite true: * masks have their length tweaked, so we have rtsock_fix_netmask() hack * IPv6 addresses have their scope embedded, so we have another explicit deembedding hack. Change the code to decouple rtentry internals from rtsock code using newly-created rtentry accessors. This will allow to eventually eliminate both of the hacks and change rtentry dst/mask format.

* acpi: Ensure that adjacent memory affinity table entries are coalescedMark Johnston2020-12-181-12/+25
| | | | | | | | | | | | | | | | | | | | The SRAT may contain multiple distinct entries that together describe a contiguous region of physical memory. In this case we were not coalescing the corresponding entries in the memory affinity table, which led to fragmented phys_avail[] entries. Since r338431 the vm_phys_segs[] entries derived from phys_avail[] will be coalesced, resulting in a situation where vm_phys_segs[] entries do not have a covering phys_avail[] entry. vm_page_startup() will not add such segments to the physical memory allocator, leaving them unused.

* Fix abort in jemalloc extent coalescing.Marcin Wojtas2020-12-181-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix error in extent_try_coalesce_impl(), which could cause abort to happen when trying to coalesce extents backwards. The error could happen because of how extent_before_get() function works. This function gets address of previous extent, by subtracting page size from current extent address. If current extent is located at PAGE_SIZE offset, this address resolved to 0x0000. An assertion in rtree_leaf_elm_lookup then caused the running program to abort. This problem was discovered when trying to build world on 32-bit machines with ASLR and PIE enabled. The problem was encountered on armv7 and i386 machines, but most likely other 32-bit architectures are affected as well. While this patch fixes one problem with buildworld on 32-bit platforms with ASLR, the build still fails, however it happens much later and due to lack of memory. The change is aligned with accepted fix in the upstream Jemalloc repository (https://github.com/jemalloc/jemalloc/pull/1973). As it doesn't apply on top of Jemalloc tree, its updated version was eventually merged: https://github.com/jemalloc/jemalloc/pull/2003 PR: 249937 Submitted by: Dawid Gorecki <dgr@semihalf.com> Obtained from: Semihalf Sponsored by: Stormshield Differential Revision: https://reviews.freebsd.org/D27025 Notes: svn path=/head/; revision=368756
