John W. Linville says:

====================
Here is one last(?) big wireless bits pull request before the merge window...

Regarding the mac80211 bits, Johannes says:

"Here's another big pull request for the -next stream. This one has a ton
of driver updates, which hopefully addresses all drivers, but maybe you
have more new drivers than I have in my tree? Not entirely sure, let me
know if this is the case and then I can merge wireless-next.

I'm including a large number of small changes, see the shortlog. The two
bigger things are making VHT compatible with not using channel contexts
(from Karl) and the stop-while-suspended fixes I developed together with
Stanislaw."

...and...

"This time I have a relatively large number of fixes and small
improvements, the most important one being Bob's RCU fix. The two big
things are Felix's work on rate scaling tables (with a big thanks to
Karl too) and my own work on CSA handling to finally properly handle HT
(and some VHT.)"

As for the iwlwifi bits, Johannes says:

"The biggest work here is Bluetooth coexistence and power saving. Other
than that, I have a few small fixes that weren't really needed for 3.9
and a new PCI ID."

About the NFC bits, Samuel says:

"With this one we have:

- A major pn533 update. The pn533 framing support has been changed in order to
  easily support all pn533 derivatives. For example we now support the ACR122
  USB dongle.

- An NFC MEI physical layer code factorization through the mei_phy NFC API.
  Both the microread and the pn544 drivers now use it.

- LLCP aggregation support. This allows NFC p2p devices to send aggregated
  frames containing all sort of LLCP frames except SYMM and aggregation
  frames.

- More LLCP socket options for getting the remote device link parameters.

- Fixes for the LLCP socket option code added with the first pull request for
  3.10.

- Some support for LLCP corner cases like 0 length SDUs and general DISC
  (tagged with a 0,0 dsap ssap couple) handling.

- RFKILL support for NFC."

For the b43 bits, Rafał says:

"Let me remind the changes for b43:
> Changes include:
> 1) Minor improvements for HT-PHY code (BCM4331)
> 2) Code cleaning for HT-PHY and N-PHY"

Concerning the bluetooth bits, Gustavo says:

"A set of changes intended for 3.10. The biggest changes here are from David
Herrmann, he rewrote most of the HIDP layer making it more reliable. Marcel
added a driver setup stage for device that need special handling on their
early initialization. Other than that we have the usual clean ups, bugfixes
and small improvements."

Along with all that, there is the usual collection of random/various
updates to ath9k, mwifiex, brcmfmac, brcmsmac, rt2x00, and wil6210.

I also included a pull of the wireless tree to resolve a merge conflict.

Please let me know if there are problems!

VXLAN: Allow L2 redirection with L3 switching

Allow L2 redirection when VXLAN L3 switching is enabled

This patch restricts L3 switching to destination MAC addresses that are
marked as routers in order to allow virtual IP appliances that do L2
redirection to function with VXLAN L3 switching enabled.

We use L3 switching on VXLAN networks to avoid extra hops when the nominal
router for cross-subnet traffic for a VM is remote and the ultimate
destination may be local, or closer to the local node. Currently, the
destination IP address takes precedence over the MAC address in all cases.
Some network appliances receive packets for a virtualized IP address and
redirect by changing the destination MAC address (only) to be the final
destination for packet processing. VXLAN tunnel endpoints with L3 switching
enabled may then overwrite this destination MAC address based on the packet IP
address, resulting in potential loops and, at least, breaking L2 redirections
that travel through tunnel endpoints.

This patch limits L3 switching to the intended case where the original
destination MAC address is a next-hop router and relies on the destination
MAC address for all other cases, thus allowing L2 redirection and L3 switching
to coexist peacefully.

xen-netback: don't disconnect frontend when seeing oversize packet

overflows the length field in the first slot making the following slots have
an invalid length.

Turn this error back into a non-fatal error by dropping the packet. To avoid

11 years agoxen-netback: coalesce slots in TX path and fix regressions
Wei Liu [Mon, 22 Apr 2013 02:20:42 +0000 (02:20 +0000)]
xen-netback: coalesce slots in TX path and fix regressions

This patch tries to coalesce tx requests when constructing grant copy
structures. It enables netback to deal with situation when frontend's
MAX_SKB_FRAGS is larger than backend's MAX_SKB_FRAGS.

With the help of coalescing, this patch tries to address two regressions
avoid reopening the security hole in XSA-39.

Regression 1. The reduction of the number of supported ring entries (slots)
per packet (from 18 to 17). This regression has been around for some time but
remains unnoticed until XSA-39 security fix. This is fixed by coalescing
slots.

Regression 2. The XSA-39 security fix turning "too many frags" errors from
just dropping the packet to a fatal error and disabling the VIF. This is fixed
by coalescing slots (handling 18 slots when backend's MAX_SKB_FRAGS is 17)
which rules out false positive (using 18 slots is legit) and dropping packets
using 19 to `max_skb_slots` slots.

To avoid reopening security hole in XSA-39, frontend sending packet using more
than max_skb_slots is considered malicious.

The behavior of netback for packet is thus:

    1-18            slots: valid
   19-max_skb_slots slots: drop and respond with an error
   max_skb_slots+   slots: fatal error

max_skb_slots is configurable by admin, default value is 20.

Also change variable name from "frags" to "slots" in netbk_count_requests.

Please note that RX path still has dependency on MAX_SKB_FRAGS. This will be
fixed with separate patch.
