genetlink: fix genl_set_err() group ID
Fix another really stupid bug - I introduced genl_set_err() precisely to be able to adjust the group and reject invalid ones, but then forgot to do so. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net> |

genetlink: fix genlmsg_multicast() bug
Unfortunately, I introduced a tremendously stupid bug into genlmsg_multicast() when doing all those multicast group changes: it adjusts the group number, but then passes it to genlmsg_multicast_netns() which does that again. Somehow, my tests failed to catch this, so add a warning into genlmsg_multicast_netns() and remove the offending group ID adjustment. Also add a warning to the similar code in other functions so people who misuse them are more loudly warned. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: David S.

net: rework recvmsg handler msg_name and msg_namelen logic
This patch now always passes msg->msg_namelen as 0. recvmsg handlers must set msg_namelen to the proper size <= sizeof(struct sockaddr_storage) to return msg_name to the user. This prevents numerous uninitialized memory leaks we had in the recvmsg handlers and makes it harder for new code to accidentally leak uninitialized memory. Optimize for the case recvfrom is called with NULL as address. We don't need to copy the address at all, so set it to NULL before invoking the recvmsg handler. We can do so, because all the recvmsg handlers must cope with the case a plain read() is called on them. read() also sets msg_name to NULL. Also document these changes in include/linux/net.h as suggested by David Miller. Changes since RFC: Set msg->msg_name = NULL if user specified a NULL in msg_name but had a non-null msg_namelen in verify_iovec/verify_compat_iovec. This doesn't affect sendto as it would bail out earlier while trying to copy-in the address. It also more naturally reflects the logic by the callers of verify_iovec. With this change in place I could remove " if (!uaddr || msg_sys->msg_namelen == 0) msg->msg_name = NULL ". This change does not alter the user visible error logic as we ignore msg_namelen as long as msg_name is NULL. Also remove two unnecessary curly brackets in ___sys_recvmsg and change comments to netdev style.

Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller:
"Mostly these are fixes for fallout due to merge window changes, as
well as cures for problems that have been with us for a much longer
period of time"
1) Johannes Berg noticed two major deficiencies in our genetlink
registration. Some genetlink protocols we passing in constant
counts for their ops array rather than something like
ARRAY_SIZE(ops) or similar. Also, some genetlink protocols were
using fixed IDs for their multicast groups.
We have to retain these fixed IDs to keep existing userland tools
working, but reserve them so that other multicast groups used by
other protocols can not possibly conflict.
In dealing with these two problems, we actually now use less state
management for genetlink operations and multicast groups.
2) When configuring interface hardware timestamping, fix several
drivers that simply do not validate that the hwtstamp_config value
is one the driver actually supports. From Ben Hutchings.
3) Invalid memory references in mwifiex driver, from Amitkumar Karwar.
4) In dev_forward_skb(), set the skb->protocol in the right order
relative to skb_scrub_packet(). From Alexei Starovoitov.
5) Bridge erroneously fails to use the proper wrapper functions to make
calls to netdev_ops->ndo_vlan_rx_{add,kill}_vid. Fix from Toshiaki
Makita.
6) When detaching a bridge port, make sure to flush all VLAN IDs to
prevent them from leaking, also from Toshiaki Makita.
7) Put in a compromise for TCP Small Queues so that deep queued devices
that delay TX reclaim non-trivially don't have such a performance
decrease. One particularly problematic area is 802.11 AMPDU in
wireless. From Eric Dumazet.
8) Fix crashes in tcp_fastopen_cache_get(), we can see NULL socket dsts
here. Fix from Eric Dumzaet, reported by Dave Jones.
9) Fix use after free in ipv6 SIT driver, from Willem de Bruijn.
10) When computing mergeable buffer sizes, virtio-net fails to take the
virtio-net header into account. From Michael Dalton.
11) Fix seqlock deadlock in ip4_datagram_connect() wrt. statistic
bumping, this one has been with us for a while. From Eric Dumazet.
12) Fix NULL deref in the new TIPC fragmentation handling, from Erik
Hugne.
13) 6lowpan bit used for traffic classification was wrong, from Jukka
Rissanen.
14) macvlan has the same issue as normal vlans did wrt. propagating LRO
disabling down to the real device, fix it the same way. From Michal
Kubecek.
15) CPSW driver needs to soft reset all slaves during suspend, from
Daniel Mack.
16) Fix small frame pacing in FQ packet scheduler, from Eric Dumazet.
17) The xen-netfront RX buffer refill timer isn't properly scheduled on
partial RX allocation success, from Ma JieYue.
18) When ipv6 ping protocol support was added, the AF_INET6 protocol
initialization cleanup path on failure was borked a little. Fix
from Vlad Yasevich.
19) If a socket disconnects during a read/recvmsg/recvfrom/etc that
blocks we can do the wrong thing with the msg_name we write back to
userspace. From Hannes Frederic Sowa. There is another fix in the
works from Hannes which will prevent future problems of this nature.
20) Fix route leak in VTI tunnel transmit, from Fan Du.

genetlink: make multicast groups const, prevent abuse
Register generic netlink multicast groups as an array with the family and give them contiguous group IDs. Then instead of passing the global group ID to the various functions that send messages, pass the ID relative to the family - for most families that's just 0 because the only have one group. This avoids the list_head and ID in each group, adding a new field for the mcast group ID offset to the family. At the same time, this allows us to prevent abusing groups again like the quota and dropmon code did, since we can now check that a family only uses a group it owns.

quota/genetlink: use proper genetlink multicast APIs
The quota code is abusing the genetlink API and is using its family ID as the multicast group ID, which is invalid and may belong to somebody else (and likely will.) Make the quota code use the correct API, but since this is already used as-is by userspace, reserve a family ID for this code and also reserve that group ID to not break userspace assumptions.

genetlink: only pass array to genl_register_family_with_ops()
As suggested by David Miller, make genl_register_family_with_ops() a macro and pass only the array, evaluating ARRAY_SIZE() in the macro, this is a little safer. The openvswitch has some indirection, assing ops/n_ops directly in that code. This might ultimately just assign the pointers in the family initializations, saving the struct genl_family_and_ops and code (once mcast groups are handled differently.)

- a new frontend (cx24117)
- a new I2C camera flash driver (lm3560)
- a new mem2mem driver for TI SoC (ti-vpe)
- support for Raphael r828d added to r820t driver
- some improvements on buffer allocation at VB2 core
- usual driver fixes and improvements
PS this time, we have a smaller number of patches. While it is hard
to pinpoint to the reasons, I believe that it is mainly due to:
1) there are several patch series ready, but depending on DT review.
I decided to grant some extra time for DT maintainers to look on
it, as they're expecting to have more time with the changes agreed
during ARM mini-summit and KS. If they can't review in time for
3.14, I'll review myself and apply for the next merge window.
2) I suspect that having both LinuxCon EU and LinuxCon NA happening
during the same merge window affected the development
productivity, as several core media developers participated on
both events"

IB/core: Remove ib_uverbs_flow_spec structure from userspace
The structure holding any types of flow_spec is of no use to userspace. It would be wrong for userspace to do: struct ib_uverbs_flow_spec flow_spec; flow_spec.type = IB_FLOW_SPEC_TCP; flow_spec.size = sizeof(flow_spec); Instead, userspace should use the dedicated flow_spec structure for - Ethernet : struct ib_uverbs_flow_spec_eth, - IPv4 : struct ib_uverbs_flow_spec_ipv4, - TCP/UDP : struct ib_uverbs_flow_spec_tcp_udp. In other words, struct ib_uverbs_flow_spec is a "virtual" data structure that can only be use by the kernel as an alias to the other.

IB/core: clarify overflow/underflow checks on ib_create/destroy_flow
This patch fixes the following issues: 1. Unneeded checks were removed 2. Removed the fixed size out of flow_attr.size, thus simplifying the checks. 3. Remove a 32bit hole on 64bit systems with strict alignment in struct ib_kern_flow_att by adding a reserved field.

This batch of changes is mostly clean ups and small bug fixes.
The only real feature that was added this release is from Namhyung Kim, who introduced "set_graph_notrace" filter that lets you run the function graph tracer and not trace particular functions and their call chain. Tom Zanussi added some updates to the ftrace multibuffer tracing that made it more consistent with the top level tracing. One of the fixes for perf function tracing required an API change in RCU; the addition of "rcu_is_watching()". As Paul McKenney is pushing that change in this release too, he gave me a branch that included all the changes to get that working, and I pulled that into my tree in order to complete the perf function tracing fix. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (GNU/Linux) iQEcBAABAgAGBQJSgX5SAAoJEKQekfcNnQGulUAH/jORqJrKaNAulmZ314VsAqfa zMtF5UAAPf7kqc3AN/jtFrhJUNEfxWOo7A4r0FsM/rKdWJF+98GA6aqYVD+XoWFt +36fg1enxbXUjixQ96Uh+o1+BJUgYDqljuWzqSu/oiXWfWwl8+WL4kcbhb+V9WcF SpdzLCWVZRfhyDiN3+0zvyQ8RSG2Pd7CWn9zroI0e4sxGo0Ki6JUnIcXtZGOBDOQ IIZdjXvGSfpJ+3u3XvRPXJcltRCtOsVWxYzrmvRlmHDW5QMe1+WmmrlojTePrLaJ xn8+3WINqetAR+ZQnazbpt1XzJzKa8QtFgpiN0kT6qL7cg3N1Owc4vLGohl7wok= =Nesf -----END PGP SIGNATURE----- Merge tag 'trace-3.13' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing update from Steven Rostedt: "This batch of changes is mostly clean ups and small bug fixes.

The /dev/random changes for 3.13 including a number of improvements in
the following areas: performance, avoiding waste of entropy, better tracking of entropy estimates, support for non-x86 platforms that have a register which can't be used for fine-grained timekeeping, but which might be good enough for the random driver. Also add some printk's so that we can see how quickly /dev/urandom can get initialized, and when programs try to use /dev/urandom before it is fully initialized (since this could be a security issue). This shouldn't be an issue on x86 desktop/laptops --- a test on my Lenovo T430s laptop shows that /dev/urandom is getting fully initialized approximately two seconds before the root file system is mounted read/write --- this may be an issue with ARM and MIPS embedded/mobile systems, though. These printk's will be a useful canary before potentially adding a future change to start blocking processes which try to read from /dev/urandom before it is initialized, which is something FreeBSD does already for security reasons, and which security folks have been agitating for Linux to also adopt. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (GNU/Linux) iQIcBAABCAAGBQJShC4MAAoJENNvdpvBGATwC0QQAMujsIxTZnsHwQrbb5eJf1kD 74TwQyEfWw5qnGQrc8JOoAbe1MG7C4QlfHxRsWxvCD8G+Mft4Q5ZgZOt0/ecAGD6 Tid58EaZGSfK9+YE6jgvJFekQADCREdPSxBASJ3cECT6dXXBX9IqR9gbAK02mM+w QZdbgWBMsPJZiHSsCNeRbZ9oIiPdcNDsMJwzJhirPUeAnKCaX3z+LWc3XcMw7wYi q5cSl0ENZd6QsBKs37A1ol5BtLEsoot2t3HKdnpOBsDQKSJ712KduwN5jUfs6h9D 0fqmVHwfKsge+D8/3NgBKz+yWLQnGkuB4Ibo+09BZXwH3rYU1/gKm0iLNi0yQ5fV 73bn4pqF6cZdDNgj0Ic+MyYAW+S/NOQ6TcF/3eSAPW6z/wHZOfZ2njCh1GEHBOKI 6iZZu+Ek7QyFJ/z5Fr1bXFJR7V99r7hRD3gwMCMZ/mjhloB2cyD0a2A9kFP85ykI I4tFEnq0FpX/K60ag4hiLnqVx/TsmbdMoz+8OpQckHgQJrZMuRRf1d+T4au47Y6K uXGLpSuvkALYW2koo2OoO2d873N/89fqFL8lI8Iy0YlgAxxxm++gl1Mql/E1wPOa 5jB0lW/jex/CquE7meTgRlM/fTU/HVbe3608ZNUYBJUHS9K/PaSnCCu2ya8/TsSW xeVS/vMnNvtGerdEIyKm =wla0 -----END PGP SIGNATURE----- Merge tag 'random_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/random Pull /dev/random changes from Ted Ts'o: "The /dev/random changes for 3.13 including a number of improvements in the following areas: performance, avoiding waste of entropy, better tracking of entropy estimates, support for non-x86 platforms that have a register which can't be used for fine-grained timekeeping, but which might be good enough for the random driver.

net: Handle CHECKSUM_COMPLETE more adequately in pskb_trim_rcsum().
Currently pskb_trim_rcsum() just balks on CHECKSUM_COMPLETE packets and remarks them as CHECKSUM_NONE, forcing a software checksum validation later. We have all of the mechanics available to fixup the skb->csum value, even for complicated fragmented packets, via the helpers skb_checksum() and csum_sub(). So just use them. Based upon a suggestion by Herbert Xu. Signed-off-by: David S. Miller <davem@davemloft.net> |

pkt_sched: fq: fix pacing for small frames
For performance reasons, sch_fq tried hard to not setup timers for every
sent packet, using a quantum based heuristic : A delay is setup only if
the flow exhausted its credit.
Problem is that application limited flows can refill their credit
for every queued packet, and they can evade pacing.
This problem can also be triggered when TCP flows use small MSS values,
as TSO auto sizing builds packets that are smaller than the default fq
quantum (3028 bytes)
This patch adds a 40 ms delay to guard flow credit refill.
Fixes:

Now that the ops assignment is just two variables rather than a long list iteration etc., there's no reason to separately export __genl_register_family() and __genl_register_family_with_ops().

AS3722 PMIC and for STMicroelectronics STw481x PMIC.
Although this is a smaller update than usual, we also have:
- Device tree support for the max77693 driver.
- linux/of.h inclusion for all DT compatible MFD drivers, to avoid build
breakage in the future.
- Support for Intel Wildcat Point-LP PCH through the lpc_ich driver.
- A small arizona update for new wm5110 DSP registers and a few fixes.
- A small palmas update as well, including an of_device table addition
and a few minor fixes.
- Two small mfd-core changes, one including a memory leak fix for when
mfd_add_device() fails.
- Our usual round of minor cleanups and janitorial fixes.

Introduce helper function macvlan_dev_real_dev which returns the underlying device of a macvlan device, similar to vlan_dev_real_dev() for 802.1q VLAN devices. v2: IFF_MACVLAN flag and equivalent of is_macvlan_dev() were introduced in the meantime v3: do BUG() if compiled without macvlan support Signed-off-by: Michal Kubecek <mkubecek@suse.cz> Signed-off-by: David S.

Here are the 3.13 KVM changes. There was a lot of work on the PPC
side: the HV and emulation flavors can now coexist in a single kernel is probably the most interesting change from a user point of view. On the x86 side there are nested virtualization improvements and a few bugfixes. ARM got transparent huge page support, improved overcommit, and support for big endian guests. Finally, there is a new interface to connect KVM with VFIO. This helps with devices that use NoSnoop PCI transactions, letting the driver in the guest execute WBINVD instructions. This includes some nVidia cards on Windows, that fail to start without these patches and the corresponding userspace changes. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQIcBAABAgAGBQJShPAhAAoJEBvWZb6bTYbyl48P/297GgmELHAGBgjvb6q7yyGu L8+eHjKbh4XBAkPwyzbvUjuww5z2hM0N3JQ0BDV9oeXlO+zwwCEns/sg2Q5/NJXq XxnTeShaKnp9lqVBnE6G9rAOUWKoyLJ2wItlvUL8JlaO9xJ0Vmk0ta4n2Nv5GqDp db6UD7vju6rHtIAhNpvvAO51kAOwc01xxRixCVb7KUYOnmO9nvpixzoI/S0Rp1gu w/OWMfCosDzBoT+cOe79Yx1OKcpaVW94X6CH1s+ShCw3wcbCL2f13Ka8/E3FIcuq vkZaLBxio7vjUAHRjPObw0XBW4InXEbhI1DjzIvm8dmc4VsgmtLQkTCG8fj+jINc dlHQUq6Do+1F4zy6WMBUj8tNeP1Z9DsABp98rQwR8+BwHoQpGQBpAxW0TE0ZMngC t1caqyvjZ5pPpFUxSrAV+8Kg4AvobXPYOim0vqV7Qea07KhFcBXLCfF7BWdwq/Jc 0CAOlsLL4mHGIQWZJuVGw0YGP7oATDCyewlBuDObx+szYCoV4fQGZVBEL0KwJx/1 7lrLN7JWzRyw6xTgJ5VVwgYE1tUY4IFQcHu7/5N+dw8/xg9KWA3f4PeMavIKSf+R qteewbtmQsxUnvuQIBHLs8NRWPnBPy+F3Sc2ckeOLIe4pmfTte6shtTXcLDL+LqH NTmT/cfmYp2BRkiCfCiS =rWNf -----END PGP SIGNATURE----- Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm Pull KVM changes from Paolo Bonzini: "Here are the 3.13 KVM changes.

Pull Xen updates from Konrad Rzeszutek Wilk:
"This has tons of fixes and two major features which are concentrated
around the Xen SWIOTLB library.
The short <blurb> is that the tracing facility (just one function) has
been added to SWIOTLB to make it easier to track I/O progress.
Additionally under Xen and ARM (32 & 64) the Xen-SWIOTLB driver
"is used to translate physical to machine and machine to physical
addresses of foreign[guest] pages for DMA operations" (Stefano) when
booting under hardware without proper IOMMU.
There are also bug-fixes, cleanups, compile warning fixes, etc.
The commit times for some of the commits is a bit fresh - that is b/c
we wanted to make sure we have the Ack's from the ARM folks - which
with the string of back-to-back conferences took a bit of time. Rest
assured - the code has been stewing in #linux-next for some time.

kfifo API type safety
This patch enhances the type safety for the kfifo API. It is now safe to put const data into a non const FIFO and the API will now generate a compiler warning when reading from the fifo where the destination address is pointing to a const variable. As a side effect the kfifo_put() does now expect the value of an element instead a pointer to the element. This was suggested Russell King. It make the handling of the kfifo_put easier since there is no need to create a helper variable for getting the address of a pointer or to pass integers of different sizes. IMHO the API break is okay, since there are currently only six users of kfifo_put(). The code is also cleaner by kicking out the "if (0)" expressions.
