sysctl: Support vdso_enabled sysctl on SH.

2007-03-05T05:13:26Z

All of the logic for this was already in place, we just hadn't wired it up in the sysctl table. Signed-off-by: Paul Mundt

[PATCH] sysctl: add a parent entry to ctl_table and set the parent entry

2007-02-14T16:10:00Z

Add a parent entry into the ctl_table so you can walk the list of parents and find the entire path to a ctl_table entry. Signed-off-by: Eric W. Biederman Cc: Stephen Smalley Cc: James Morris Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] sysctl: reimplement the sysctl proc support

2007-02-14T16:10:00Z

With this change the sysctl inodes can be cached and nothing needs to be done when removing a sysctl table. For a cost of 2K code we will save about 4K of static tables (when we remove de from ctl_table) and 70K in proc_dir_entries that we will not allocate, or about half that on a 32bit arch. The speed feels about the same, even though we can now cache the sysctl dentries :( We get the core advantage that we don't need to have a 1 to 1 mapping between ctl table entries and proc files. Making it possible to have /proc/sys vary depending on the namespace you are in. The currently merged namespaces don't have an issue here but the network namespace under /proc/sys/net needs to have different directories depending on which network adapters are visible. By simply being a cache different directories being visible depending on who you are is trivial to implement.

[PATCH] sysctl: factor out sysctl_head_next from do_sysctl

2007-02-14T16:09:59Z

The current logic to walk through the list of sysctl table headers is slightly painful and implement in a way it cannot be used by code outside sysctl.c I am in the process of implementing a version of the sysctl proc support that instead of using the proc generic non-caching monster, just uses the existing sysctl data structure as backing store for building the dcache entries and for doing directory reads. To use the existing data structures however I need a way to get at them. [akpm@osdl.org: warning fix] Signed-off-by: Eric W. Biederman Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] sysctl: remove insert_at_head from register_sysctl

2007-02-14T16:09:59Z

The semantic effect of insert_at_head is that it would allow new registered sysctl entries to override existing sysctl entries of the same name. Which is pain for caching and the proc interface never implemented. I have done an audit and discovered that none of the current users of register_sysctl care as (excpet for directories) they do not register duplicate sysctl entries. So this patch simply removes the support for overriding existing entries in the sys_sysctl interface since no one uses it or cares and it makes future enhancments harder. Signed-off-by: Eric W.

[PATCH] sysctl: remove support for directory strategy routines

2007-02-14T16:09:59Z

parse_table has support for calling a strategy routine when descending into a directory. To date no one has used this functionality and the /proc/sys interface has no analog to it. So no one is using this functionality kill it and make the binary sysctl code easier to follow. Signed-off-by: Eric W. Biederman Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] sysctl: remove support for CTL_ANY

2007-02-14T16:09:59Z

There are currently no users in the kernel for CTL_ANY and it only has effect on the binary interface which is practically unused. So this complicates sysctl lookups for no good reason so just remove it. Signed-off-by: Eric W. Biederman Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] sysctl: create sys/fs/binfmt_misc as an ordinary sysctl entry

2007-02-14T16:09:59Z

binfmt_misc has a mount point in the middle of the sysctl and that mount point is created as a proc_generic directory. Doing it that way gets in the way of cleaning up the sysctl proc support as it continues the existence of a horrible hack. So instead simply create the directory as an ordinary sysctl directory. At least that removes the magic special case. [akpm@osdl.org: warning fix] Signed-off-by: Eric W. Biederman Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
