sysctl: Error on bad sysctl tables

2007-10-18T21:37:23+00:00

After going through the kernels sysctl tables several times it has become
clear that code review and testing is just not effective in prevent
problematic sysctl tables from being used in the stable kernel.  I certainly
can't seem to fix the problems as fast as they are introduced.

Therefore this patch adds sysctl_check_table which is called when a sysctl
table is registered and checks to see if we have a problematic sysctl table.

The biggest part of the code is the table of valid binary sysctl entries, but
since we have frozen our set of binary sysctls this table should not need to
change, and it makes it much easier to detect when someone unintentionally
adds a new binary sysctl value.

As best as I can determine all of the several hundred errors spewed on boot up
now are legitimate.

sysctl: properly register the irda binary sysctl numbers

2007-10-18T21:37:23+00:00

Grumble.  These numbers should have been in sysctl.h from the beginning if we
ever expected anyone to use them.  Oh well put them there now so we can find
them and make maintenance easier.

sysctl: Factor out sysctl_data.

2007-10-18T21:37:22+00:00

There as been no easy way to wrap the default sysctl strategy routine except
for returning 0.  Which is not always what we want.  The few instances I have
seen that want different behaviour have written their own version of
sysctl_data.  While not too hard it is unnecessary code and has the potential
for extra bugs.

So to make these situations easier and make that part of sysctl more symetric
I have factord sysctl_data out of do_sysctl_strategy and exported as a
function everyone can use.

Further having sysctl_data be an explicit function makes checking for badly
formed sysctl tables much easier.

sysctl core: Stop using the unnecessary ctl_table typedef

2007-10-18T21:37:22+00:00

In sysctl.h the typedef struct ctl_table ctl_table violates coding style isn't
needed and is a bit of a nuisance because it makes it harder to recognize
ctl_table is a type name.

So this patch removes it from the generic sysctl code.  Hopefully I will have
enough energy to send the rest of my patches will follow and to remove it from
the rest of the kernel.

"[PATCH] Get rid of /proc/sys/proc" was good commit except strace(1) compile
breakage it introduced:

[TCP]: Add two new spurious RTO responses to FRTO

2007-04-26T05:23:23+00:00

New sysctl tcp_frto_response is added to select amongst these
responses:
	- Rate halving based; reuses CA_CWR state (default)
	- Very conservative; used to be the only one available (=1)
	- Undo cwr; undoes ssthresh and cwnd reductions (=2)

The response with rate halving requires a new parameter to
tcp_enter_cwr because FRTO has already reduced ssthresh and
doing a second reduction there has to be prevented. In addition,
to keep things nice on 80 cols screen, a local variable was
added.
