* Install the 4th files in sys/boot/forth instead of each loaderWarner Losh2017-11-101-15/+6
| | | | | | | | | | | | | | | | | | | | | | | | Also, move generation of loader.help into loader.mk. Set HELP_FILES= to disable this (so we only install one help file, for now). At the same time remove some duplicate -I lines. Fix several FILES= and CLEANFILES= into the += form since we're touching both of those in the .mk files. Make sure we only build one loader.help file per platform in a unified way (we were building many on some, with the last to install winning, though often they were the same text). Also, we're now installing loader.rc and menu.rc everywhere. arm and mips uboot installed these as menu.rc.sample, but there's no need since the loader.rc for those platforms doesn't do menu.rc processing by default. pcibios.4th is now installed everywhere, but will failsafe on non x86 platforms (it isn't loaded by default anywhere). These changes are too intertwined to do separately since aspects of each are required to have a bug-free commit. Sponsored by: Netflix Notes: svn path=/head/; revision=325694

* Remove LOADER_ZFS_SUPPORT as a Makefile variableWarner Losh2017-11-101-7/+0
| | | | | | | | | | | | | LOADER_ZFS_SUPPORT is entirely used to select whether or not to support ZFS in the loader. But it's not a user-servicable part (MK_ZFS is what's used for that) Change it to the more conventional HAVE_ZFS and move the ZFS support code into loader.mk. In addition, only build ZFS libraries and boot loaders when ZFS is enabled. Sponsored by: Netflix Notes: svn path=/head/; revision=325690
* loader: set options before including bsd.init.mkRoger Pau Monné2017-11-081-12/+12
| | | | | | | | | | | | | | | | | bsd.init.mk ends up including defs.mk so the per-arch options must be set before including defs.mk, or else the global defaults will be used and the per-arch ones will be ignored. Although better, note that the usage of MK_FDT before the inclusion of bsd.init.mk is incorrect but doesn't lead to build errors. This circular dependency must be broken in order for this to work correctly. Reviewed by: imp Sponsored by: Citrix Systems R&D Notes: svn path=/head/; revision=325556

| | | | | | | | | | | | | | | | | | | | | | | | | | | 1. 50+% of NO_PIE use is fixed by adding -fPIC to INTERNALLIB and other build-only utility libraries. 2. Another 40% is fixed by generating _pic.a variants of various libraries. 3. Some of the NO_PIE use is a bit absurd as it is disabling PIE (and ASLR) where it never would work anyhow, such as csu or loader. This suggests there may be better ways of adding support to the tree. Many of these cases can be fixed such that -fPIE will work but there is really no reason to have it in those cases. 4. Some of the uses are working around hacks done to some Makefiles that are really building libraries but have been using bsd.prog.mk because the code is cleaner. Had they been using bsd.lib.mk then NO_PIE would not have been needed. We likely do want to enable PIE by default (opt-out) for non-tree consumers (such as ports). For in-tree though we probably want to only enable PIE (opt-in) for common attack targets such as remote service daemons and setuid utilities. This is also a great performance compromise since ASLR is expected to reduce performance. As such it does not make sense to enable it in all utilities such as ls(1) that have little benefit to having it enabled. Reported by: kib Notes: svn path=/head/; revision=270168
* Give loaders more control over the Forth initialization process. InMarcel Moolenaar2014-07-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | particular, allow loaders to define the name of the RC script the interpreter needs to use. Use this new-found control to have the PXE loader (when compiled with TFTP support and not NFS support) read from ${bootfile}.4th, where ${bootfile} is the name of the file fetched by the PXE firmware. The normal startup process involves reading the following files: 1. /boot/boot.4th 2. /boot/loader.rc or alternatively /boot/boot.conf When these come from a FreeBSD-defined file system, this is all good. But when we boot over the network, subdirectories and fixed file names are often painful to administrators and there's really no way for them to change the behaviour of the loader.

The strong definitions are provided in libzfsboot. This change mean that the size of i386_devspec becomes larger to match zfs_devspec. Backward-compatibility shims are provided for recently added sparc64 zfs boot support. Currently that architecture still works the old way and does not support the new features.

Steps for ZFS booting: 1. create VTOC8 label # gpart create -s vtoc8 da0 2. add partitions, f.e.: # gpart add -t freebsd-zfs -s 60g da0 # gpart add -t freebsd-swap da0 resulting in something like: # gpart show => 0 143331930 da0 VTOC8 (68G) 0 125821080 1 freebsd-zfs (60G) 125821080 17510850 2 freebsd-swap (8.4G) 3. create zpool # zpool create bunker da0a or for mirror/RAIDZ (after preparing additional disks as in steps 1. + 2.): # zpool create bunker mirror da0a da1a # zpool create bunker raidz da0a da1a da2a ... 4. set bootfs # zpool set bootfs=bunker bunker 5. install zfsboot # zpool export bunker # gpart bootcode -p /boot/zfsboot da0 6. write zfsloader to the ZFS Boot Block (so far, there's no dedicated tool for this, so dd(1) has to be used for this purpose) When using mirror/RAIDZ, step 4. and the dd(1) invocation should be repeated for the additional disks in order to be able to boot from another disk in case of failure. # sysctl kern.geom.debugflags=0x10 # dd if=/boot/zfsloader of=/dev/da0a bs=512 oseek=1024 conv=notrunc # zpool import bunker 7. install system on ZFS filesystem Don't forget to set 'zfs_load="YES"' and vfs.root.mountfrom="zfs:bunker" in loader.conf as well as 'zfs_enable="YES"'in rc.conf. 8. copy zpool.cache to the ZFS filesystem cp -p /boot/zfs/zpool.cache /bunker/boot/zfs/zpool.cache 9. set mountpoint # zfs set mountpoint=/ bunker 10. Now, given that aliases for all disks in the zpool exists (check with the `devalias` command on the boot monitor prompt) and disk0 corresponds to da0 (likewise for additional disks), the system can be booted from the ZFS with: {1} ok boot disk0 PR: 165025 Submitted by: Gavin Mu Notes: svn path=/head/; revision=234898

Also flushing the unlocked kernel entries can cause instant faults which when called from within cpu_switch() are handled with the scheduler lock held which in turn can cause timeouts on the acquisition of the lock by other CPUs. This was easily seen with a 16-core V890 but occasionally also happened with 2-way machines. While at it, move the SPARC64-V support code entirely to zeus.c.
