| | | | | | | | | | | | | | | | | | | - EFI support appeared in 5.0 for ia64 - arm64 UEFI support added in 11.0 The AUTHORS section included the folks responsible for the bulk of the work to bring UEFI support to amd64, but missed those who did the original work on ia64, the initial port to i386, the ports to arm64 and arm, and have generally maintained and improved general UEFI support since then. It's unwieldly to include everyone and would quickly become outdated again anyhow, so just remove the AUTHORS section.

* Add libregex, connect it to the buildKyle Evans2018-01-222-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | libregex is a regex(3) implementation intended to feature GNU extensions and any other non-POSIX compliant extensions that are deemed worthy. These extensions are separated out into a separate library for the sake of not cluttering up libc further with them as well as not deteriorating the speed (or lack thereof) of the libc implementation. libregex is implemented as a build of the libc implementation with LIBREGEX defined to distinguish this from a libc build. The reasons for implementation like this are two-fold: 1.) Maintenance- This reduces the overhead induced by adding yet another regex implementation to base. 2.) Ease of use- Flipping on GNU extensions will be as simple as linking against libregex, and POSIX-compliant compilations can be guaranteed with a REG_POSIX cflag that should be ignored by libc/regex and disables extensions in libregex. It is also easier to keep REG_POSIX sane and POSIX pure when implemented in this fashion. Tests are added for future functionality, but left disconnected for the time being while other testing is done.

* Introduce aw_syscon(4) for earlier attachmentKyle Evans2018-01-132-0/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Attaching syscon_generic earlier than BUS_PASS_DEFAULT makes it more difficult for specific syscon drivers to attach to the syscon node and to get ordering right. Further discussion yielded the following set of decisions: - Move syscon_generic to BUS_PASS_DEFAULT - If a platform needs a syscon with different attach order or probe behavior, it should subclass syscon_generic and match on the SoC specific compat string - When we come across a need for a syscon that attaches earlier but only specifies compatible = "syscon", we should create a syscon_exclusive driver that provides generic access but probes earlier and only matches if "syscon" is the only compatible. Such fdt nodes do exist in the wild right now, but we don't really use them at the moment. Additionally: - Any syscon provider that has needs any more complex than a spinlock solely for syscon access and a single memory resource should subclass syscon directly rather than attempting to subclass syscon_generic or add complexity to it. syscon_generic's attach/detach methods may be made public should the need arise to subclass it with additional attach/detach behavior. We introduce aw_syscon(4) that just subclasses syscon_generic but probes earlier to meet our requirements for if_awg and implements #2 above for this specific situation. It currently only matches a64/a83t/h3 since these are the only platforms that really need it at the time being.

* Enable ld.lld as bootstrap linker by default on i386Ed Maste2018-01-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Akin to r327783 for amd64. lld has been usable for amd64 for quite some time, but a couple of issues remained that affected i386. These were recently addressed upstream in lld and merged into FreeBSD (r326831, r326879, r326897, r326957), so we can now use ld.lld on i386 as well. Similarly to amd64 this change enables lld only as the bootstrap linker (used to link the kernel and userland libraries and executables), while GNU ld.bfd is still installed as /usr/bin/ld and used for ports builds. The ports collection is essentially ready to use lld as the system linker for amd64, but many ports still have trouble with lld on i386, because lld defaults to -ztext, disallowing relocations against readonly segments. Thus switching the system linker (WITH_LLD_IS_LD) will happen later on a per-arch basis. Relnotes: Yes Sponsored by: The FreeBSD Foundation Notes: svn path=/head/; revision=327823

WOULD_OVERFLOW() should be a secondary check -- on 64-bit platforms, just because an allocation won't overflow size_t does not mean it is a sane size to request. Callers should be imposing reasonable allocation limits far, far, below overflow. Discussed with: emaste, jhb, kp Sponsored by: Dell EMC Isilon Notes: svn path=/head/; revision=327796

* Enable ld.lld as bootstrap linker by default on amd64Ed Maste2018-01-101-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For some time we have been planning to migrate to LLVM's lld linker. Having a man page was the last blocking issue for using ld.lld to link the base system kernel + userland, now addressed by r327770. Link the kernel and userland libraries and binaries with ld.lld by default, for additional test coverage. This has been a long time in the making. On 2013-04-13 I submitted an upstream tracking issue in LLVM PR 23214: [META] Using LLD as FreeBSD's system linker. Since then 85 individual issues were identified, and submitted as dependencies. These have been addressed along with two and a half years of other lld development and improvement. I'd like to express deep gratitude to upstream lld developers Rui Ueyama, Rafael Espindola, George Rimar and Davide Italiano. They put in substantial effort in addressing the issues we found affecting FreeBSD/amd64. To revert to using ld.bfd as the bootstrap linker, in /etc/src.conf set WITHOUT_LLD_BOOTSTRAP=yes If you need to set this, please follow up with a PR or post to the freebsd-toolchain mailing list explaining how default WITH_LLD_BOOTSTRAP failed for your use case. Note that GNU ld.bfd is still installed as /usr/bin/ld, and will still be used for linking ports. ld.lld can be installed as /usr/bin/ld by setting in /etc/src.conf WITH_LLD_IS_LLD=yes A followup commit will set WITH_LLD_IS_LD by default, possibly after Clang/LLVM/lld 6.0 is merged to FreeBSD.

* Generalize the gzio API.Mark Johnston2018-01-081-12/+13
| | | | | | | | | | | | | | | | | | | We currently use a set of subroutines in kern_gzio.c to perform compression of user and kernel core dumps. In the interest of adding support for other compression algorithms (zstd) in this role without complicating the API consumers, add a simple compressor API which can be used to select an algorithm. Also change the (non-default) GZIO kernel option to not enable compressed user cores by default. It's not clear that such a default would be desirable with support for multiple algorithms implemented, and it's inconsistent in that it isn't applied to kernel dumps.
