exec_conf.c

Delete the last emulation callbacks: we're Just ELF, so declare exec_elf_fixup() and coredump_elf() in <sys/exec_elf.h> and call them and the MD setregs() directly in kern_exec.c and kern_sig.c

uprintf() is the wrong way to show this error to a user's tty (I am not sure there is a right way)

Implement the POSIX-2024 close-on-fork flag, but modified to be reset on exec as preserving it across exec is not necessary for its original purpose and has security and usability concerns.

kern_exec.c

Fix reference counting for sigobject initialization. Simplify error handling; we can't even exec init(8) if sigobject initialization fails, so just panic and don't worry about cleaning up after ourselves. This code should always succeed.

kern_pledge.c

delete pledge_sysctl() printing of the failing mibs, because it truncates it's buffer, produces misleading output, and is pointless tty output, Like with other system calls failuress, the standard pledge_fail() tty output should lead the user to use ktrace which will provide an accurate view. discussed with bluhm

Implement a ddb stop command that sends a SIGSTOP to the specified pid.

kern_prot.c

Instead of failing with EINVAL when setthrname(2) is passed a thread name longer then _MAXCOMLEN-1, truncate the name to fit. This is likely what the user wants and saves them from having to snprintf(3) into a buffer sized _MAXCOMLEN first. Man page update to follow.

kern_subr.c

On systems without xonly mmu hardware-enforcement, we can still mitigate against classic BROP with a range-checking wrapper in front of copyin() and copyinstr() which ensures the userland source doesn't overlap the main program text, ld.so text, signal tramp text (it's mapping is hard to distinguish so it comes along for the ride), or libc.so text. ld.so tells the kernel libc.so text range with msyscall(2). The range checking for 2-4 elements is done without locking (because all 4 ranges are immutable!) and is inexpensive.

Introduce a generic powerbutton_event() function that does everything we expect from a power button event in a consistent manner. This gets rid of some duplicated code and means all drivers now prevent shutdown within the first 10 seconds after resume.

syscalls.master

In the old gprof profiling subsystem, the simplistic profil() syscall told the kernel about the sample buffer, and then the normal exit-time _mcleanup() would finalize the buffer, open()'ed a file and write out the details. This file opening has become increasingly impossible because of our privsep / privdrop, chroot, setresuid uid-dropping, pledge, unveil, and other efforts. So people stopped using gprof. Programs which needed profiling needed substantial mitigation removal changes to put them under test.
