Biederman" Date: Fri, 3 Apr 2009 00:09:33 -0700 Subject: [PATCH 02/43] 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.

Biederman" Date: Fri, 3 Apr 2009 00:36:27 -0700 Subject: [PATCH 03/43] 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.

Biederman" Date: Thu, 5 Nov 2009 05:26:41 -0800 Subject: [PATCH 12/43] sysctl: Reduce sys_sysctl to a compatibility wrapper around /proc/sys To simply maintenance and to be able to remove all of the binary sysctl support from various subsystems I have rewritten the binary sysctl code as a compatibility wrapper around proc/sys. The code is built around a hard coded table based on the table in sysctl_check.c that lists all of our current binary sysctls and provides enough information to convert from the sysctl binary input into into ascii and back again. New in this patch is the realization that the only dynamic entries that need to be handled have ifname as the asscii string and ifindex as their ctl_name. When a sys_sysctl is called the code now looks in the translation table converting the binary name to the path under /proc where the value is to be found. Opens that file, and calls into a format conversion wrapper that calls fop->read and then fop->write as appropriate. Since in practice the practically no one uses or tests sys_sysctl rewritting the code to be beautiful is a little silly. The redeeming merit of this work is it allows us to rip out all of the binary sysctl syscall support from everywhere else in the tree. Allowing us to remove a lot of dead (after this patch) and barely maintained code. In addition it becomes much easier to optimize the sysctl implementation for being the backing store of /proc/sys, without having to worry about sys_sysctl. Signed-off-by: Eric W.

Biederman" Date: Fri, 3 Apr 2009 03:18:02 -0700 Subject: [PATCH 16/43] sysctl: Don't look at ctl_name and strategy in the generic code The ctl_name and strategy fields are unused, now that sys_sysctl is a compatibility wrapper around /proc/sys. No longer looking at them in the generic code is effectively what we are doing now and provides the guarantee that during further cleanups we can just remove references to those fields and everything will work ok.

Remove them. Remove a smattering of ctl_names used in sysctl paths, and kill the ctl_names in the recently added mach-bcmring. mach-bcmring never should have had sysctl entries with .ctl_name set. The binary sysctl interface has been frozen for a long time before that code was merged, to prevent probmes with conflicts and lack of testing. The sysctl_check code would have caught this if anyone had ever tested it that way. So I have simply dropped the binary sysctl support instead of adding another compat entry into sysctl_binary.c. Going through /proc/sys/reboot/warm will still work. Cc: Leo Chen Cc: Russell King Signed-off-by: Eric W.

Biederman" Date: Fri, 20 Nov 2009 09:12:22 -0800 Subject: [PATCH 42/43] security/tomoyo: Add a special case to handle accesses through the internal proc mount. With the change of sys_sysctl going through the internal proc mount we no longer need to handle security_sysctl in tomoyo as we have valid pathnames for all sysctl accesses. There is one slight caveat to that in that all of the paths from the internal mount look like "/sys/net/ipv4/ip_local_port_range" instead of "/proc/sys/net/ipv4/ip_local_port_range" so tomoyo needs to add the "/proc" portion manually when resolving to full path names to get what it expects. This change teaches tomoyo perform that modification. Acked-by: Tetsuo Handa Acked-by: John Johansen Signed-off-by: Eric W.
