sysctl: Make do_sysctl static ... Now that all of the architectures use compat_sys_sysctl do_sysctl can become static. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Eric W. Biederman   commited 2009-11-06 03:53:59 -08:00	642c6d946b
sysctl: Introduce a generic compat sysctl sysctl ... This uses compat_alloc_userspace to remove the various hacks to allow do_sysctl to write to throuh oldlenp. The rest of our mature compat syscall helper facitilies are used as well to ensure we have a nice clean maintainable compat syscall that can be used on all architectures. The motiviation for a generic compat sysctl (besides the obvious hack removal) is to reduce the number of compat sysctl defintions out there so I can refactor the binary sysctl implementation. ppc already used the name compat_sys_sysctl so I remove the ppcs version here.

sysctl: Refactor the binary sysctl handling to remove duplicate code ... Read in the binary sysctl path once, instead of reread it from user space each time the code needs to access a path element. The deprecated sysctl warning is moved to do_sysctl so that the compat_sysctl entries syscalls will also warn. The return of -ENOSYS when !CONFIG_SYSCTL_SYSCALL is moved to binary_sysctl. Always leaving a do_sysctl available that handles !CONFIG_SYSCTL_SYSCALL and printing the deprecated sysctl warning allows for a single defitition of the sysctl syscall. Signed-off-by: Eric W.

sysctl: Separate the binary sysctl logic into it's own file. ... In preparation for more invasive cleanups separate the core binary sysctl logic into it's own file. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Eric W. Biederman   commited 2009-11-06 03:20:07 -08:00	afa588b265
