Hello, Daniel:
can all your examples block early before doing network operations? What's the whole netfilter universe? Can you give us more clear examples?
Thanks

I gave one simple example for blocking in the commit message, that's true, but it is not limited to that, meaning we can have much different scenarios/policies that netfilter allows us than just blocking, e.g. fine grained settings where applications are allowed to connect/send traffic to, application traffic marking/ conntracking, application-specific packet mangling, and so on, just think of the whole netfilter universe.

vortex_down() does a lot of other things which are really dangerous
from an interrupt handler, such as del_timer_sync().
The real fix for this bug is to defer the vortex_error() work into
a workqueue, and thus process context, like every other driver does.

Too bad, it's a necessary API change to fix the bug, the users
will need to change too.
It's not our problem if they are out-of-tree and can't be fixed
in-situ.

Ok I will do that. But I think this API change must go into net-next, right?
Otherwise we would break every existing user.
What about resending this patch to net (after having removed the pskb_may_pull()
as pointed out by Eric) and then fixing the API in net-next?

Then this hook's API needs to be fixed, it's completely broken.
Make it pass the SKB and the appropriate offset (from skb->data) in
bytes.

Still doesn't apply.
Email this patch to yourself, I bet the patch you receive won't
apply cleanly. Likely your email client is corrupting the patch.
You've already eaten enough of my time as a maintainer submitting
a patch that won't even apply. Absolutely do not resubmit this
patch until you can email the patch successfully to yourself
and successfuly apply the patch you receive in that email to
the current net-next tree.

Submit these, not individually as single patches, but as a patch set,
the first one with subject "[PATCH 1/2]" and the second with
subject "[PATCH 2/2]"
You have to do this, because it is absolutely essentially to let
me know which patch gets applies first and which one gets applied
second. The two patches are to the same file, so if you don't
tell me the order, they won't apply cleanly at all.

But rx_hook() does not receive any skb:
609 np->rx_hook(np, ntohs(uh->source),
610 (char *)(uh+1),
611 ulen - sizeof(struct udphdr));
it just receives a pointer to the data and can't do anything to make it linear.
(uh is a pointer to the udp header). Am I missing something?

* [PATCH 10/15] net: sis190: remove unnecessary pci_set_drvdata()
From: Jingoo Han @ 2013-10-22 4:18 UTC (permalink / raw)
To: 'David S. Miller'

In-Reply-To: <000601cecedd$1981e300$4c85a900$%han@samsung.com>
The driver core clears the driver data to NULL after device_release
or on probe failure. Thus, it is not needed to manually clear the
device driver data to NULL.
