commit 885c252ffb059dc493200bdb981bdd21cabe4442
Author: Matthew Garrett <mjg@redhat.com>
Date: Thu Dec 9 18:31:59 2010 -0500
PCI: _OSC "supported" field should contain supported features, not enabled ones
From testing with Windows, the call to the PCI root _OSC method includes
the full set of features supported by the operating system even if the
hardware has already indicated that it doesn't support ASPM or MSI.
https://bugzilla.redhat.com/show_bug.cgi?id=638912 is a case where making
the _OSC call will incorrectly configure the chipset unless the supported
field has bits 1, 2 and 4 set. Rework the functionality to ensure that
we match this behaviour.

Jon Masters correctly points out that conntrack hash sizes
(nf_conntrack_htable_size) are global (not per-netns) and
modifiable at runtime via /sys/module/nf_conntrack/hashsize .
Steps to reproduce:
clone(CLONE_NEWNET)
[grow /sys/module/nf_conntrack/hashsize]
exit()
At netns exit we are going to scan random memory for conntracks to be killed.
Apparently there is a code which deals with hashtable resize for
init_net (and it was there befode netns conntrack code), so prohibit
hashsize modification if there is more than one netns exists.
To change hashtable sizes, you need to reload module.
Expectation hashtable size was simply glued to a variable with no code
to rehash expectations, so it was a bug to allow writing to it.
Make "expect_hashsize" readonly.
This is temporarily until we figure out what to do.
