Reported by: Ilja Van Sprundel Approved by: re (kensmith) 2006-09-03T08:06:59Z Robert Watson rwatson@FreeBSD.org 2006-09-03T08:06:59Z urn:sha1:f93dba474357d3440c1e3078c099d762d409c3b1 to RELENG_6: Audit the arguments to the kill(2) and killpg(2) system calls. Audit the arguments to the ptrace(2) system call. Make sure that we are adding a path token to the audit record in open(2). Do this by making sure we are using the AUDITVNODE1 mask in the namei flags.

This includes Simplifying the cleanup code in kern_ptrace() and removing the now unnecessary vmspace ref counting magic from proc_rwmem(). Also, the locking for ptrace_single_step(), ptrace_set_pc(), and ptrace_clear_single_step() have been fixed to be consistent across the tree.

We use this at work. ia32_reg.[ch]: handle the 32 bit register file format, used by ptrace, procfs and core dumps. procfs_*regs.c: vary the format of proc/XXX/*regs depending on the client and target application. procfs_map.c: Don't print a 64 bit value to 32 bit consumers, or their sscanf fails. They expect an unsigned long. imgact_elf.c: produce a valid 32 bit coredump for 32 bit apps. sys_process.c: handle 32 bit consumers debugging 32 bit targets. Note that 64 bit consumers can still debug 32 bit targets. IA64 has got stubs for ia32_reg.c. Known limitations: a 5.x/6.x gdb uses get/setcontext(), which isn't implemented in the 32/64 wrapper yet. We also make a tiny patch to gdb pacify it over conflicting formats of ld-elf.so.1.
