Modified Files: src/lib/libc/gen: posix_spawn_fileactions.c src/sys/compat/netbsd32: netbsd32.h netbsd32_execve.c syscalls.master src/sys/kern: exec_elf.c kern_exec.c kern_exit.c src/sys/sys: exec.h spawn.h src/sys/uvm: uvm_extern.h uvm_glue.c uvm_map.c src/tests/lib/libc/gen/posix_spawn: t_fileactions.c Log Message: Rework posix_spawn locking and memory management: - always provide a vmspace for the new proc, initially borrowing from proc0 (this part fixes PR 46286) - increase parallelism between parent and child if arguments allow this, avoiding a potential deadlock on exec_lock - add a new flag for userland to request old (lockstepped) behaviour for better error reporting - adapt test cases to the previous two and add a new variant to test the diagnostics flag - fix a few memory (and lock) leaks - provide netbsd32 compat To generate a diff of this commit: cvs rdiff -u -r1.1 -r1.2 src/lib/libc/gen/posix_spawn_fileactions.c cvs rdiff -u -r1.94 -r1.95 src/sys/compat/netbsd32/netbsd32.h \ src/sys/compat/netbsd32/syscalls.master cvs rdiff -u -r1.33 -r1.34 src/sys/compat/netbsd32/netbsd32_execve.c cvs rdiff -u -r1.37 -r1.38 src/sys/kern/exec_elf.c cvs rdiff -u -r1.347 -r1.348 src/sys/kern/kern_exec.c cvs rdiff -u -r1.237 -r1.238 src/sys/kern/kern_exit.c cvs rdiff -u -r1.134 -r1.135 src/sys/sys/exec.h cvs rdiff -u -r1.1 -r1.2 src/sys/sys/spawn.h cvs rdiff -u -r1.182 -r1.183 src/sys/uvm/uvm_extern.h cvs rdiff -u -r1.158 -r1.159 src/sys/uvm/uvm_glue.c cvs rdiff -u -r1.316 -r1.317 src/sys/uvm/uvm_map.c cvs rdiff -u -r1.3 -r1.4 src/tests/lib/libc/gen/posix_spawn/t_fileactions.c Please note that diffs are not public domain; they are subject to the copyright notices on the relevant files.
