      arm64: Widen hwcap to be 64 bit · 25804e6a
      由 Steve Capper 提交于 
      Under arm64 elf_hwcap is a 32 bit quantity, but it is stored in
a 64 bit auxiliary ELF field and glibc reads hwcap as 64 bit.

This patch widens elf_hwcap to be 64 bit.

      arm64: documentation: tighten up tagged pointer documentation · 374ed9d1
      由 Will Deacon 提交于 
      Commit d50240a5 ("arm64: mm: permit use of tagged pointers at EL0")
added support for tagged pointers in userspace, but the corresponding
update to Documentation/ contained some imprecise statements.

This patch fixes up some minor ambiguities in the text, hopefully making
it more clear about exactly what the kernel expects from user virtual
addresses.

      Pull ARM SoC fixes from Olof Johansson:
 "A set of fixes for ARM platforms for 3.12.  Among them:

   - A fix for build breakage in the MTD subsystem for some PXA devices.
     David Woodhouse has this patch in his for-next branch but has not
     been responding to our requests to send it up so here it is.  I
     should have amended the commit message to describe the build
     failure for CONFIG_OF=n setups, but forgot and now it's down in the
     stack of commits.

   - Added device-tree for the BeagleBone Black.  Turns out people have
     been using the older "regualar" bone DT for the newer boards, and
     there's risk of damaging hardware that way.

   - Misc DT and regular fixes for OMAP.

   - Fix to make the ST-Ericsson "snowball" boards boot with
     multi_v7_defconfig, and enable one of the ST-E reference boards on
     the same config.

   - Kconfig cleanup for u300 to hide submenus when the platform isn't
     enabled.

   - Enable ARM_ATAG_DTB_COMPAT to let firmware override command line
     when booting with an appended devicetree on non-DT-enabled firmware
     (needed to boot snowball)"

      Pull networking fixes from David Miller:

 1) If the local_df boolean is set on an SKB we have to allocate a
    unique ID even if IP_DF is set in the ipv4 headers, from Ansis
    Atteka.

 2) Some fixups for the new chipset support that went into the sfc
    driver, from Ben Hutchings.

 3) Because SCTP bypasses a good chunk of, and actually duplicates, the
    logic of the ipv6 output path, some IPSEC things don't get done
    properly.  Integrate SCTP better into the ipv6 output path so that
    these problems are fixed and such issues don't get missed in the
    future either.  From Daniel Borkmann.

 4) Fix skge regressions added by the DMA mapping error return checking
    added in v3.10, from Mikulas Patocka.

 5) Kill some more IRQF_DISABLED references, from Michael Opdenacker.

 6) Fix races and deadlocks in the bridging code, from Hong Zhiguo.

 7) Fix error handling in tun_set_iff(), in particular don't leak
    resources.  From Jason Wang.

 8) Prevent format-string injection into xen-netback driver, from Kees
    Cook.

 9) Fix regression added to netpoll ARP packet handling, in particular
    check for the right ETH_P_ARP protocol code.  From Sonic Zhang.

10) Try to deal with AMD IOMMU errors when using r8169 chips, from
    Francois Romieu.

11) Cure freezes due to recent changes in the rt2x00 wireless driver,
    from Stanislaw Gruszka.

12) Don't do SPI transfers (which can sleep) in interrupt context in
    cw1200 driver, from Solomon Peachy.

13) Fix LEDs handling bug in 5720 tg3 chips already handled for 5719.
    From Nithin Sujir.

14) Make xen_netbk_count_skb_slots() count the actual number of slots
    that will be used, taking into consideration packing and other
    issues that the transmit path will run into.  From David Vrabel.

15) Use the correct maximum age when calculating the bridge
    message_age_timer, from Chris Healy.

16) Get rid of memory leaks in mcs7780 IRDA driver, from Alexey
    Khoroshilov.

17) Netfilter conntrack extensions were converted to RCU but are not
    always freed properly using kfree_rcu().  Fix from Michal Kubecek.

18) VF reset recovery not being done correctly in qlcnic driver, from
    Manish Chopra.

19) Fix inverted test in ATM nicstar driver, from Andy Shevchenko.

20) Missing workqueue destroy in cxgb4 error handling, from Wei Yang.

21) Internal switch not initialized properly in bgmac driver, from Rafał
    Miłecki.

22) Netlink messages report wrong local and remote addresses in IPv6
    tunneling, from Ding Zhi.

23) ICMP redirects should not generate socket errors in DCCP and SCTP.
    We're still working out how this should be handled for RAW and UDP
    sockets.  From Daniel Borkmann and Duan Jiong.

24) We've had several bugs wherein the network namespace's loopback
    device gets accessed after it is free'd, NULL it out so that we can
    catch these problems more readily.  From Eric W Biederman.

25) Fix regression in TCP RTO calculations, from Neal Cardwell.

26) Fix too early free of xen-netback network device when VIFs still
    exist.  From Paul Durrant.

      netconsole: fix a deadlock with rtnl and netconsole's mutex · c71380ff
      由 Nikolay Aleksandrov 提交于 
      This bug was introduced by commit
7a163bfb ("netconsole: avoid a crash with
multiple sysfs writers"). In store_enabled() we have the following
sequence: acquire nt->mutex then rtnl, but in the netconsole netdev
notifier we have rtnl then nt->mutex effectively leading to a deadlock.
The NULL pointer dereference that the above commit tries to fix is
actually due to another bug in netpoll_cleanup(). This is fixed by dropping
the mutex from the netdev notifier as it's already protected by rtnl.

      由 Nikolay Aleksandrov 提交于 
      I've been hitting a NULL ptr deref while using netconsole because the
np->dev check and the pointer manipulation in netpoll_cleanup are done
without rtnl and the following sequence happens when having a netconsole
over a vlan and we remove the vlan while disabling the netconsole:
	CPU 1					CPU2
					removes vlan and calls the notifier
enters store_enabled(), calls
netdev_cleanup which checks np->dev
and then waits for rtnl
					executes the netconsole netdev
					release notifier making np->dev
					== NULL and releases rtnl
continues to dereference a member of
np->dev which at this point is == NULL

      skge: fix broken driver · c194992c
      由 Mikulas Patocka 提交于 
      The patch 136d8f37 broke the skge driver.
Note this part of the patch:
+               if (skge_rx_setup(skge, e, nskb, skge->rx_buf_size) < 0) {
+                       dev_kfree_skb(nskb);
+                       goto resubmit;
+               }
+
                pci_unmap_single(skge->hw->pdev,
                                 dma_unmap_addr(e, mapaddr),
                                 dma_unmap_len(e, maplen),
                                 PCI_DMA_FROMDEVICE);
                skb = e->skb;
                prefetch(skb->data);
-               skge_rx_setup(skge, e, nskb, skge->rx_buf_size);

The function skge_rx_setup modifies e->skb to point to the new skb. Thus,
after this change, the new buffer, not the old, is returned to the
networking stack.

This bug is present in kernels 3.11, 3.11.1 and 3.12-rc1. The patch should
be queued for 3.11-stable.

      ip: generate unique IP identificator if local fragmentation is allowed · 703133de
      由 Ansis Atteka 提交于 
      If local fragmentation is allowed, then ip_select_ident() and
ip_select_ident_more() need to generate unique IDs to ensure
correct defragmentation on the peer.

For example, if IPsec (tunnel mode) has to encrypt large skbs
that have local_df bit set, then all IP fragments that belonged
to different ESP datagrams would have used the same identificator.
If one of these IP fragments would get lost or reordered, then
peer could possibly stitch together wrong IP fragments that did
not belong to the same datagram. This would lead to a packet loss
or data corruption.

      xen-netback: Don't destroy the netdev until the vif is shut down · 279f438e
      由 Paul Durrant 提交于 
      Without this patch, if a frontend cycles through states Closing
and Closed (which Windows frontends need to do) then the netdev
will be destroyed and requires re-invocation of hotplug scripts
to restore state before the frontend can move to Connected. Thus
when udev is not in use the backend gets stuck in InitWait.

With this patch, the netdev is left alone whilst the backend is
still online and is only de-registered and freed just prior to
destroying the vif (which is also nicely symmetrical with the
netdev allocation and registration being done during probe) so
no re-invocation of hotplug scripts is required.
