* Provide an MD 64-bit byteswapping function build on 32-bit swapsnaddy2018-10-051-2/+11
| | | | | | | | | | | | | as we do on arm and i386. Copied from arm. If there are no MD byteswapping functions, MI macros are used. These are wrapped by static inline functions to prevent multiple evaluation of their argument. If there are MD functions, they are used directly and therefore we must implicitly guarantee that they are safe from multiple evaluation. Defining an MD function to an MI macro breaks this promise. ok deraadt@
* Unify the MD byteswapping code as much as possible across architectures.naddy2018-10-021-21/+26
| | | | | | | Use inline functions instead of GNU C statement expressions, and make them available to userland. With clues from guenther@. ok guenther@ kettenis@
* Unify and bump some of the NMBCLUSTERS defines. Some archs had it set toclaudio2018-09-141-2/+2
| | | | | | | | | 4MB which is far too low especially when the platform is able to run MP. New limits are, amd64 = 256M; arm64, mips64, sparc64 = 64M; alpha, arm, hppa, i386, powerpc = 32M; m88k, sh = 8M Still rather conservative numbers but much better than before. At least some hangs of arm64 build boxes was caused by this. OK kettenis@, visa@
* Move from sendsig() to its callers the initsiginfo() calls andguenther2018-07-101-4/+3
| | | | | | | | instead of passing sendsig() the code+type+val, pass a siginfo_t* to copy from. Eliminate the indirection through struct emul for sendsig(); we no longer have a SunOS4-compat version of sendsig() ok deraadt@
* Implement MAP_STACK option for mmap(). Synchronous faults (pagefault andderaadt2018-04-121-3/+3
| | | | | | | | | | | | | | syscall) confirm the stack register points at MAP_STACK memory, otherwise SIGSEGV is delivered. sigaltstack() and pthread_attr_setstack() are modified to create a MAP_STACK sub-region which satisfies alignment requirements. Observe that MAP_STACK can only be set/cleared by mmap(), which zeroes the contents of the region -- there is no mprotect() equivalent operation, so there is no MAP_STACK-adding gadget. This opportunistic software-emulation of a stack protection bit makes stack-pivot operations during ROPchain fragile (kind of like removing a tool from the toolbox). original discussion with tedu, uvm work by stefan, testing by mortimer ok kettenis
* Do not panic from ddb(4) when a lock requirement isn't fulfilled.mpi2018-03-201-3/+1
| | | | | | | | | | | Extend the logic already present for panic() to any DDB-related operation such that if ddb(4) is entered because of a fault or other trap it is still possible to call 'boot reboot'. While here stop printing splassert() messages as well, to not fill the buffer. ok visa@, deraadt@
* #define _MAX_PAGE_SHIFT in MD _types.h as the maximum pagesize an archderaadt2018-03-051-1/+2
| | | | | | | | | | needs (looking at you sgi, but others required this before). This is for the circumstances we need pagesize known at compile time, not getpagesize() runtime. Use it for malloc storage sizes, for shm, and to set pthread stack default sizes. The stack sizes were a mess, and pushing them towards page-aligned is healthy move (which will also be needed by the coming stack register checker) ok guenther kettenis, discussion with stefan
* Remove almost unused `flags' argument of suser().mpi2018-02-192-5/+5
| | | | | | | The account flag `ASU' will no longer be set but that makes suser() mpsafe since it no longer mess with a per-process field. No objection from millert@, ok tedu@, bluhm@

* Split up fork1():guenther2017-02-121-15/+14
| | | | | | | | | | | | | | | | | - FORK_THREAD handling is a totally separate function, thread_fork(), that is only used by sys___tfork() and which loses the flags, func, arg, and newprocp parameters and gains tcb parameter to guarantee the new thread's TCB is set before the creating thread returns - fork1() loses its stack and tidptr parameters Common bits factor out: - struct proc allocation and initialization moves to thread_new() - maxthread handling moves to fork_check_maxthread() - setting the new thread running moves to fork_thread_start() The MD cpu_fork() function swaps its unused stacksize parameter for a tcb parameter. luna88k testing by aoyama@, alpha testing by dlg@ ok mpi@

| | | | | | | | | | | | | | | | | | | | | | 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@

* Make a move towards ending 4 decades of kernel snooping.deraadt2016-09-251-2/+6
| | | | | | | | | | | | | | | 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
* all pools have their ipl set via pool_setipl, so fold it into pool_init.dlg2016-09-151-6/+4
| | | | | | | | | | | | | | | | | | | | | | 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);
