2019-08-04crank version, following fchmod changeTheo de Raadt
2019-08-03In the bootblocks, after discovering and opening /bsd.upgrade, fchmod -xTheo de Raadt
so the file cannot be re-executed upon the next boot. This provides a stronger one-shot-upgrade model than the upgrade script's rm /bsd.upgrade. Now various forms of upgrade failure will reboot into /bsd, which is probably more recoverable. Performing fchmod -x depends on (1) use of MI boot.c (not alpha/macppc/sparc64/sgi/octeon) and (2) "can write blocks" functionality in the IO layer. Most architectures have this support now. Two diagnostics "fchmod a-x %s: failed" and "/bsd.upgrade is not u+x" will remain in the tree while refinements happen for some of the laggard architectures. based upon a discussion florian tested in snapshots for more than a week without any complaints
2019-06-21Further improve the filesystem stability of kernel installation by KARL.Theo de Raadt
Use install -F to instead of cp, for fsync(2). Coupled with the new sync(8) in the reorder_kernel script, the window for a incomplete /bsd file on-disk due to a crash has now shrunk substantially. Discussion with kettenis, millert and tedu

2019-04-20libsa's memcpy() is actually memmove(). make a proper memmove(), and giveTheo de Raadt
memcpy() correct behaviour. This also brings the bcopy() macro into line.
2019-04-14Instead of using COPTS=-Oz (and similar) in make environment to forceTheo de Raadt
tightly-built ramdisk kernels, set the option in per-arch Makefile.inc based upon SMALL_KERNEL
2019-04-14Update shared drm code, inteldrm(4) and radeondrm(4) from linux 4.4 toJonathan Gray
linux 4.19.34. Adds support for more Intel hardware: Broxton/Apollo Lake (was is_preliminary in 4.4) Amber Lake (another Kaby Lake refresh) Gemini Lake Coffee Lake Whiskey Lake Cannon Lake (though no hardware with Intel graphics ever shipped) Ice Lake (alpha support, hardware not released) This does not add support for new radeon hardware on the AMD side as newer radeons have a different kernel driver (amdgpu). Thanks to the OpenBSD Foundation for sponsoring this work, kettenis@ for helping and a bunch of other developers for testing.

2019-01-07tweak ohci_checkrev so it doesnt print a leading comma and space.David Gwynne
it assumes that it always followed an interrupt string, but we don't print that on fdt. having the bus responsible for the whitespace means the fdt glue can print a colon to separate the bus info from checkrev output, while every other glue keeps the comma. ok deraadt@

2018-04-20Add a workaround that lets loongson bootblocks work with PMON thatVisa Hankala
uses the O32 calling convention. Such firmware comes at least on some Loongson 3A development boards. This differs from the LS2F-based machines made by Lemote whose PMON uses the GCC O64 calling convention.
2018-04-20Make loongson bootblocks use disklabel duid instead of PMON device nameVisa Hankala
when indicating the boot device to the kernel. This should reduce ambiguity in root device selection.
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@
