When the VLAN tag is present in the packet buffer (i.e VLAN stripping disabled, QinQ)
the driver will currently report CHECKSUM_UNNECESSARY.
Instead of using CHECKSUM_COMPLETE offload for packets with first
ethertype of IPv4/6, use it for packets with last ethertype of IPv4/6 to
cover the former cases as well.
The checksum field present in the CQE is calculated from the IP header
until the end of the packet. When the first ethertype is different than
IPv4/6 (for ex. 802.1Q VLAN) a checksum of the VLAN header/s should be
added. The small header/s checksum calculation will allow us to use
CHECKSUM_COMPLETE instead of CHECKSUM_UNNECESSARY.

net_sched: close the race between call_rcu() and cleanup_net()
This patchset tries to fix the race between call_rcu() and
cleanup_net() again. Without holding the netns refcnt the
tc_action_net_exit() in netns workqueue could be called before
filter destroy works in tc filter workqueue. This patchset
moves the netns refcnt from tc actions to tcf_exts, without
breaking per-netns tc actions.
Patch 1 reverts the previous fix, patch 2 introduces two new
API's to help to address the bug and the rest patches switch
to the new API's. Please see each patch for details.
I was not able to reproduce this bug, but now after adding
some delay in filter destroy work I manage to trigger the
crash. After this patchset, the crash is not reproducible
any more and the debugging printk's show the order is expected
too.

Instead of holding netns refcnt in tc actions, we can minimize
the holding time by saving it in struct tcf_exts instead. This
means we can just hold netns refcnt right before call_rcu() and
release it after tcf_exts_destroy() is done.
However, because on netns cleanup path we call tcf_proto_destroy()
too, obviously we can not hold netns for a zero refcnt, in this
case we have to do cleanup synchronously. It is fine for RCU too,
the caller cleanup_net() already waits for a grace period.
For other cases, refcnt is non-zero and we can safely grab it as
normal and release it after we are done.
This patch provides two new API for each filter to use:
tcf_exts_get_net() and tcf_exts_put_net(). And all filters now can
use the following pattern:
void __destroy_filter() {
tcf_exts_destroy();
tcf_exts_put_net(); // <== release netns refcnt
kfree();
}
void some_work() {
rtnl_lock();
__destroy_filter();
rtnl_unlock();
}
void some_rcu_callback() {
tcf_queue_work(some_work);
}
if (tcf_exts_get_net()) // <== hold netns refcnt
call_rcu(some_rcu_callback);
else
__destroy_filter();

====================
net: dsa: setup stage
When probing a DSA switch, there is basically two stages.
The first stage is the parsing of the switch device, from either device
tree or platform data. It fetches the DSA tree to which it belongs, and
validates its ports. The switch device is then added to the tree, and
the second stage is called if this was the last switch of the tree.
The second stage is the setup of the tree, which validates that the tree
is complete, sets up the routing tables, the default CPU port for user
ports, sets up the switch drivers and finally the master interfaces,
which makes the whole switch fabric functional.
This patch series covers the second setup stage. The setup and teardown
of a switch tree have been separated into logical steps, and the probing
of a switch now simply parses and adds a switch to a tree.

The *_complete() functions take too much arguments to do only one thing:
they try to fetch the dsa_port structures corresponding to device nodes
under the "link" list property of DSA ports, and use them to setup the
routing table of switches.
This patch simplifies them by providing instead simpler
dsa_{port,switch,tree}_setup_routing_table functions which return a
boolean value, true if the tree is complete.
dsa_tree_setup_routing_table is called inside dsa_tree_setup which
simplifies the switch registering function as well.
A switch's routing table is now initialized before its setup.
This also makes dsa_port_is_valid obsolete, remove it.

The OF code provides a of_for_each_phandle() helper to iterate over

The of_phandle_iterator_next() helper calls of_node_put() itself on

Commit 7744ccdbc1 ("x86/mm: Add Secure Memory Encryption (SME)
support") as a side-effect made PAGE_KERNEL all of a sudden unavailable
to modules which can't make use of EXPORT_SYMBOL_GPL() symbols.
This is because once SME is enabled, sme_me_mask (which is introduced as
EXPORT_SYMBOL_GPL) makes its way to PAGE_KERNEL through _PAGE_ENC,
causing imminent build failure for all the modules which make use of all
the EXPORT-SYMBOL()-exported API (such as vmap(), __vmalloc(),
remap_pfn_range(), ...).
Exporting (as EXPORT_SYMBOL()) interfaces (and having done so for ages)
that take pgprot_t argument, while making it impossible to -- all of a
sudden -- pass PAGE_KERNEL to it, feels rather incosistent.
Restore the original behavior and make it possible to pass PAGE_KERNEL
to all its EXPORT_SYMBOL() consumers.
[ This is all so not wonderful. We shouldn't need that "sme_me_mask"
access at all in all those places that really don't care about that
level of detail, and just want _PAGE_KERNEL or whatever.
We have some similar issues with _PAGE_CACHE_WP and _PAGE_NOCACHE,
both of which hide a "cachemode2protval()" call, and which also ends
up using another EXPORT_SYMBOL(), but at least that only triggers for
the much more rare cases.
Maybe we could move these dynamic page table bits to be generated much
deeper down in the VM layer, instead of hiding them in the macros that
everybody uses.
So this all would merit some cleanup. But not today. - Linus ]
