2018-03-02Fix the locating of the OpenBSD disklabel on media with 2048 byteVisa Hankala
sectors (installXX.iso). The change to properly locate the disklabel, introduced after 6.0, assumed incorrectly 512 byte sectors. Diff from miod@
2018-02-24Declare ci_ipl volatile to prevent the compiler from optimizingVisa Hankala
or reordering accesses to the variable. Assume that the assembler preserves the correct sequence of instructions, which allows the removal of the explicit noreorder/reorder toggles from the C code. With ci_ipl being volatile, drop mips_sync() calls that follow the accesses of the variable. The sync is redundant as a compiler barrier. In addition, the MIPS64 CPU designs should not need the sync for pipeline or write buffer control. According to miod@, the use of the instruction is a carryover from code targeting early MIPS designs that lack tight integration with the cache and write buffer. Discussed with and testing help from miod@. Tested on CN5020, CN6120, CN7130, CN7360, Loongson 2F and 3A1000, R4400, R8000, R10000 and R16000.

2017-12-11In uvm Chuck decided backing store would not be allocated proactivelyTheo de Raadt
for blocks re-fetchable from the filesystem. However at reboot time, filesystems are unmounted, and since processes lack backing store they are killed. Since the scheduler is still running, in some cases init is killed... which drops us to ddb [noted by bluhm]. Solution is to convert filesystems to read-only [proposed by kettenis]. The tale follows: sys_reboot() should pass proc * to MD boot() to vfs_shutdown() which completes current IO with vfs_busy VB_WRITE|VB_WAIT, then calls VFS_MOUNT() with MNT_UPDATE | MNT_RDONLY, soon teaching us that *fs_mount() calls a copyin() late... so store the sizes in vfsconflist[] and move the copyin() to sys_mount()... and notice nfs_mount copyin() is size-variant, so kill legacy struct nfs_args3. Next we learn ffs_mount()'s MNT_UPDATE code is sharp and rusty especially wrt softdep, so fix some bugs adn add ~MNT_SOFTDEP to the downgrade. Some vnodes need a little more help, so tie them to &dead_vnops. ffs_mount calling DIOCCACHESYNC is causing a bit of grief still but this issue is seperate and will be dealt with in time. couple hundred reboots by bluhm and myself, advice from guenther and others at the hut
2017-11-04Since rev 1.502 of rc(8) it creates a /bsd.booted hard link. At theFlorian Obser
end of rc we call reorder_kernel which creates a /obsd hard link to the same kernel. In the past obsd was only created when doing a manual make install in the kernel sources. There is no need for two backup hard links during boot, rearange the kernel Makefiles to restore previous behaviour and thus stopping reorder_kernel from scribbling over /obsd. Makes muscle memory of some kernel developers work again: /obsd can serve as a known good kernel; and there was much rejoycing... Discussed at length with benno, rpe, phessler and tb at p2k17. Seems like a good idea to deraadt. OK benno, phessler, rpe, tb
2017-09-28When option DDB_STRUCTINFO was removed from the kernel, too much fromPatrick Wildt
the kernel makefiles was removed which lead to C files not being re- compiled when a dependency changed. This can lead to panics in odd places and generally a broken system. ok deraadt@

2017-06-22Generate a gap.link script, and use that to generate gap.o. On multi-ABITheo de Raadt

2017-06-08Split early startup code out of locore.S into locore0.S. Adjust linkVisa Hankala
run so that this locore0.o is always at the start of the executable. But randomize the link order of all other .o files in the kernel, so that their exec/rodata/data/bss segments land all over the place. Late during kernel boot, smash the startup code with traps so that it does not point to the other randomly placed code. It has be smashed, because sgi runs in the kseg0 or xkphys space. As a result, the internal layout of every newly build bsd kernel is different from past kernels. Internal relative offsets are not known to an outside attacker. Ramdisk kernels cannot be compiled like this, because they are gzip'd. When the internal pointer references change, the compression dictionary bloats and results in poorer compression.
