bbf31bf18d ipv4: additional update of dev_net(dev) to struct *net in ip_fragment.c, NULL ptr OOPS
ipv4 ip_frag_reasm(), fully replace 'dev_net(dev)' with 'net', defined
previously patched into 2.6.29.

Between 2.6.28.10 and 2.6.29, net/ipv4/ip_fragment.c was patched,
changing from dev_net(dev) to container_of(...).  Unfortunately the goto
section (out_fail) on oversized packets inside ip_frag_reasm() didn't
get touched up as well.  Oversized IP packets cause a NULL pointer
dereference and immediate hang.

I discovered this running openvasd and my previous email on this is
titled:  NULL pointer dereference at 2.6.32-rc8:net/ipv4/ip_fragment.c:566

In addition neigh_sysctl_register has been modified to no longer

547b792cac net: convert BUG_TRAP to generic WARN_ON
Removes legacy reinvent-the-wheel type thing. The generic
machinery integrates much better to automated debugging aids
such as kerneloops.org (and others), and is unambiguous due to
better naming. Non-intuively BUG_TRAP() is actually equal to
WARN_ON() rather than BUG_ON() though some might actually be
promoted to BUG_ON() but I left that to future.

I could make at least one BUILD_BUG_ON conversion.

9a375803fe inet fragments: fix race between inet_frag_find and inet_frag_secret_rebuild

read-locked the secret rebuild timer may occur (on another CPU, since
BHs are still disabled in the inet_frag_find) and change the rnd seed

It was caused by my patch fd9e63544c

These ones use the generic data types too, so move
them in one place.

4b6cb5d8e3 [INET]: Small cleanup for xxx_put after evictor consolidation
After the evictor code is consolidated there is no need in
passing the extra pointer to the xxx_put() functions.

The only place when it made sense was the evictor code itself.

Maybe this change must got with the previous (or with the
next) patch, but I try to make them shorter as much as
possible to simplify the review (but they are still large
anyway), so this change goes in a separate patch.

8e7999c44e [INET]: Consolidate the xxx_evictor
The evictors collect some statistics for ipv4 and ipv6,
so make it return the number of evicted queues and account
them all at once in the caller.

The XXX_ADD_STATS_BH() macros are just for this case,
but maybe there are places in code, that can make use of
them as well.
