문제
I have userspace sysctl calls made to sysctl tables configured on a 2.6.24 kernel. I have migrated the sysctl code to 2.6.35 kernel. I'm seeing warning msgs sayg that 'deprecated sysctl warning' when i make sysctl() calls from userspace. The same is workinng on 2.6.24. Does anyone have any idea on this. Also, sysctl handler do_sysctl islocated in sysctl.c in 2.6.24 whereas in 2.6.35 is located in sysctl_binary.c oa
해결책
The sysctl()
system call has long been considered deprecated; indeed the man page has said this for some time:
Or rather... don't call it: use of this system call has long been discouraged, and it is so unloved that it is likely to disappear in a future kernel version. Remove it from your programs now; use the
/proc/sys
interface instead.
As it says, you should rewrite your userspace portion of the code to use the /proc/sys
interface.
