2017-12-14fcntl(F_SETFL) invokes the FIONBIO and FIOASYNC ioctls internally, soPhilip Guenther
the memory devices (/dev/null, /dev/zero, etc) need to permit them. problem noted, tweak, and testing by jeremy@ ok deraadt@

2017-09-05Move mutex, condvar, and thread-specific data routes, pthread_once, andPhilip Guenther
pthread_exit from libpthread to libc, along with low-level bits to support them. Major bump to both libc and libpthread. Requested by libressl team. Ports testing by naddy@ ok kettenis@

2017-04-30Rename Debugger() into db_enter().Martin Pieuchot
Using a name with the 'db_' prefix makes it invisible from the dynamic profiler. ok deraadt@, kettenis@, visa@
2017-04-20Hook up mutex(9) to witness(4).Visa Hankala
2017-04-13Provide mips64 with kernel-facing TCB_{GET,SET} macros that store itPhilip Guenther
in struct mdproc. With that, all archs have those and the __HAVE_MD_TCB macro can be unifdef'ed as always defined. ok kettenis@ visa@ jsing@
2017-02-12Split up fork1():Philip Guenther
- 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@
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@
2017-01-21p_comm is the process's command and isn't per thread, so move it fromPhilip Guenther
struct proc to struct process. ok deraadt@ kettenis@

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);
2016-09-03Increase the number of mbufs on most architectures. This is basedAlexander Bluhm
on a guess how much memory a typical machine has. If the value is too high, users may run out of kernel memory. Then we will have to adjust this again. OK claudio@ deraadt@
2016-08-16remove #define for /dev/mem minors. let the raw magic of the hardcodedTed Unangst
numbers serve as a warning not to touch them.

2016-06-07consistently set ipls on pmap pools.David Gwynne
this is a step toward making ipls unconditionaly on pools. ok deraadt@ kettenis@
2016-05-27Remove the non ELF macrosTheo de Raadt
ok millert
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
2016-05-21hand-massage sendsig() and sys_sigreturn() to be much more similar.Theo de Raadt

it for the TCB pointer. Eliminate __cerror. "looks good" kettenis@, testing and ok deraadt@
2016-05-11delete SROP mitigation debug code; it worksTheo de Raadt
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

Covers all of landisk/sh, per naddy's suggestion. ok on previous diff deraadt@ naddy@
2016-02-27Rename kdb_trap() into db_ktrap().Martin Pieuchot
The goal is to include it in the list of functions that must not be instrumented. All ddb(8) functions should be in this list and have their names start with 'db_'. ok visa@, deraadt@
2016-02-26Make alpha and sh 2038-safe. Now that we have 64-bit time_t, we don'tmmcc

2015-09-30Use #ifndef _MACHINE_DISKLABEL_H_ everywhere. Replace _ARM_DISKLABEL_H_Kenneth R Westerback
and _SH_DISKLABEL_H_ with _MACHINE_DISKLABEL_H_. Add the guard to loongson and octeon. The #defines are not used anywhere else in the tree so no functional change.
2015-09-30Use consistant whitespace/comments for #define'ing LABELSECTOR,Kenneth R Westerback
LABELOFFSET and MAXPARTITIONS. Easier on the eye when scanning through all these files. No functional change.

2015-09-08Give the pool page allocator backends more sensible names. We now have:Mark Kettenis
* pool_allocator_single: single page allocator, always interrupt safe * pool_allocator_multi: multi-page allocator, interrupt safe * pool_allocator_multi_ni: multi-page allocator, not interrupt-safe ok deraadt@, dlg@

2015-07-17remove obsolete INET kernel optionTed Unangst
2015-05-15still needs kcore.hTheo de Raadt
2015-05-05emul_native is only used for kernel threads which can't dump core, soPhilip Guenther
delete coredump_trad(), uvm_coredump(), cpu_coredump(), struct md_coredump, and various #includes that are superfluous. This leaves compat_linux processes without a coredump callback. If that ability is desired, someone should update it to use coredump_elf32() and verify the results... ok kettenis@
2015-04-30Remove SIZE_MAX from limits.h. It was added years ago before weTodd C. Miller
had a proper stdint.h. No ports fallout. OK guenther@ miod@
2015-02-15Change pmap_remove_holes() to take a vmspace instead of a map as its argument.Miod Vallat
Use this on vax to correctly pick the end of the stack area now that the stackgap adjustment code will no longer guarantee it is a fixed location.
