2017-02-08In exec_elf.c: expand ELFNAME(), ELFNAME2(), and ELFNAMEEND() exceptPhilip Guenther
leaving out the size, so that ELFNAME2(exec,makecmds) becomes exec_elf_makecmds instead of exec_elf{32,64}_makecmds and then delete the ELFNAME2() and ELFNAMEEND() macros. Move the prototypes for functions local to exec_elf.c to there from exec_elf.h. Simplify the SMALL_KERNEL conditionals around the ELF coredump code. Change exec_conf.c to use the size-generic names and macros Remove exec_elf{32,64}.c and just build exec_elf.c; delete the _KERN_DO_ELF and _KERN_DO_ELF64 #defines. ok jca@, encouragement from deraadt@ and tom@
2017-01-22Introduce the KEEPKERNELS variable: if this is set either in mk.conf orTheo Buehler
the environment, 'make cleandir' does not descend into kernel build directories. Thus, kernel object files survive 'make build' on slower architectures. WARNING: If you set this variable, you run the risk of breaking 'make release': Be sure to run 'make cleandir' from /sys/arch/$(machine)/compile before doing 'make release'. This issue will be addressed shortly. requested by kettenis; ok deraadt

2016-11-29Build kernel with DEBUG=-g by default.Martin Pieuchot
This will allow us to extract type informations from DWARF2 sections. It also makes developer life easier as debug information are now included in every object. Resulting kernels will be stripped using strip(1) instead of ld(1). Kernel build time increases by approximately 10%. However it is still possible to disable this by defining DEBUG="". ok kettenis@, bluhm@, natano@, jasper@, reyk@, deraadt@
2016-11-15Clean up the kernel Makefile's:Martin Natano
- Remove the 'lint' target. lint has been removed with OpenBSD 5.2. - Remove the 'tags' target. It does nothing of value. - Replace 'clean::' with 'clean:', as requested by espie and millert, and remove files from the 'clean' target, that are never generated. - Don't create a file called 'depend' in 'make depend', but just do nothing instead. ok mpi tb

2016-11-05Two tweaks for compile/Makefile.inc:Martin Natano
1) Replace '.elif !exists(${OBJDIR}/Makefile)' with just '.else'. espie pointed out, that if the file existed, make wouldn't be reading this file, so the check is superflous. Less clutter. 2) Unconditionally define the 'clean' and 'cleandir' targets, also when obj doesn't exist. This changes the behaviour of 'make clean' to be successful (doing nothing) without obj@ or obj/. ok tb millert deraadt

reference to eddep in the kernel Makefile I could find is in 4.3BSD, released some 30 years ago. ok tb millert

2016-10-15cleandir: target for kernel compile directoriesTheo de Raadt
ok natano
2016-10-14Kernel builds now happen in compile/CONFIG/obj@ -> /usr/obj/... [or ./obj/,Theo de Raadt
if srctree is not rooted at /usr/src]. As a result, stock GENERIC & RAMDISK kernels are commited to the tree, to ensure the src tree can be "readonly" during builds, with all writes occuring inside the obj space. config -b options are handled by ../Makefile.inc. The canonical new way to configure one of these kernels is: % cd /sys/arch/amd64/compile/GENERIC.MP % doas make obj % make config % make % doas cp obj/bsd /bsd The build infrastructure will use this new mechanism in a de-escalation way using BUILDUSER. Much help from natano and tb.

2016-09-25Make a move towards ending 4 decades of kernel snooping.Theo de Raadt
Add sysctl kern.allowkmem (default 0) which controls the ability to open /dev/mem or /dev/kmem at securelevel > 0. Over 15 years we converted 99% of utilities in the tree to operate on sysctl-nodes (either by themselves or via code hiding in the guts of -lkvm). pstat -d and -v & procmap are affected and continued use of them will require kern.allowkmem=1 in /etc/sysctl.conf. acpidump (and it's buddy sendbug) are affected, but we'll work out a solution soon. There will be some impact in ports. ok kettenis guenther

2016-09-15all pools have their ipl set via pool_setipl, so fold it into pool_init.David Gwynne
the ioff argument to pool_init() is unused and has been for many years, so this replaces it with an ipl argument. because the ipl will be set on init we no longer need pool_setipl. most of these changes have been done with coccinelle using the spatch below. cocci sucks at formatting code though, so i fixed that by hand. the manpage and subr_pool.c bits i did myself. ok tedu@ jmatthew@ @ipl@ expression pp; expression ipl; expression s, a, o, f, m, p; @@ -pool_init(pp, s, a, o, f, m, p); -pool_setipl(pp, ipl); +pool_init(pp, s, a, ipl, f, m, p);

2016-05-23Place a cpu-dependent trap/illegal instruction over the remainder of theTheo de Raadt
sigtramp page, so that it will generate a nice kernel fault if touched. While here, move most of the sigtramps to the .rodata segment, because they are not executed in the kernel. Also some preparation for sliding the actual sigtramp forward (will need some gdb changes) ok mlarkin kettenis

2016-05-10SROP mitigation. sendsig() stores a (per-process ^ &sigcontext) cookieTheo de Raadt
inside the sigcontext. sigreturn(2) checks syscall entry was from the exact PC addr in the (per-process ASLR) sigtramp, verifies the cookie, and clears it to prevent sigcontext reuse. not yet tested on landisk, sparc, *88k, socppc. ok kettenis
2016-05-04Initial support for MSI-X. Only supported on amd64 for now. I have diffs toMark Kettenis
actually use this in em(4) and xhci(4), but I'm not committing those yet because we almost certainly need to save and restore the MSI-X registers during suspend/resume. However, this allows mpi@ to play with multiple-vector support in networking hardware. Requested by mpi@ ok mlarkin@, mikeb@
