Modified files:
sys/compat/linprocfs linprocfs.c
sys/compat/pecoff imgact_pecoff.c
sys/kern imgact_aout.c kern_proc.c sys_process.c
Log:
- Change fill_kinfo_proc() to require that the process is locked when it
is called.
- Change sysctl_out_proc() to require that the process is locked when it
is called and to drop the lock before it returns. If this proves too
complex we can change sysctl_out_proc() to simply acquire the lock at
the very end and have the calling code drop the lock right after it
returns.
- Lock the process we are going to export before the p_cansee() in the
loop in sysctl_kern_proc() and hold the lock until we call
sysctl_out_proc().
- Don't call p_cansee() on the process about to be exported twice in
the aforementioned loop.
