USB fixes for 3.13-rc3
Here are a bunch of USB fixes for 3.13-rc3. Nothing major, but we seem to have an argument about a XHCI fix, so I'm not including a revert that Sarah requested, because that breaks a USB network driver, and I can't revert the USB network driver fix without reintroducing other bugs that it fixed. So as it is, everything should now be working. Worse case, I can revert the XHCI fix before 3.13-final is out, but it seems to work well here with my testing, so all should be good. Other than that, some driver updates based on reports.

Power management fixes for 3.13-rc3
- cpufreq regression fix from Bjørn Mork restoring the pre-3.12
behavior of the framework during system suspend/hibernation to
avoid garbage sysfs files from being left behind in case of a
suspend error.
- PNP regression fix to restore the correct states of devices after
resume from hibernation broken in 3.12. From Dmitry Torokhov.
- cpuidle fix to prevent cpuidle device unregistration from crashing
due to a NULL pointer dereference if cpuidle has been disabled
from the kernel command line. From Konrad Rzeszutek Wilk.
- intel_idle fix for the C6 state definition on Intel Avoton/Rangeley
processors from Arne Bockholdt.
- Power capping framework fix to make the energy_uj sysfs attribute
work in accordance with the documentation. From Srinivas Pandruvada.
- epoll fix to make it ignore the EPOLLWAKEUP flag if the kernel has
been compiled with CONFIG_PM_SLEEP unset (in which case that flag
should not have any effect). From Amit Pundir.
- cpufreq fix to prevent governor sysfs files from being lost over
system suspend/resume in some (arguably unusual) situations. From
Viresh Kumar.

The other changes are: A fix to the recent consolidation and optimization of using "asm goto" with read-modify-write operation, which broke the bitops; specifically in such a way that we could end up generating invalid code. A build hack to make sure we compile with -mno-sse. icc, and most likely future versions of gcc, can generate SSE instructions unless we tell it not to.

usb: wusbcore: fix deadlock in wusbhc_gtk_rekey
When multiple wireless USB devices are connected and one of the devices disconnects, the host will distribute a new group key to the remaining devicese using wusbhc_gtk_rekey. wusbhc_gtk_rekey takes the wusbhc->mutex and holds it while it submits a URB to set the new key. This causes a deadlock in wa_urb_enqueue when it calls a device lookup helper function that takes the same lock. This patch changes wusbhc_gtk_rekey to submit a work item to set the GTK so that the URB is submitted without holding wusbhc->mutex.

iio: hid-sensors: Fix power and report state
In the original HID sensor hub firmwares all Named array enums were to 0-based. But the most recent hub implemented as 1-based, because of the implementation by one of the major OS vendor. Using logical minimum for the field as the base of enum. So we add logical minimum to the selector values before setting those fields. Some sensor hub FWs already changed logical minimum from 0 to 1 to reflect this and hope every other vendor will follow. There is no easy way to add a common HID quirk for NAry elements, even if the standard specifies these field as NAry, the collection used to describe selectors is still just "logical".

usb: xhci: Link TRB must not occur within a USB payload burst
Section 4.11.7.1 of rev 1.0 of the xhci specification states that a link TRB can only occur at a boundary between underlying USB frames (512 bytes for high speed devices). If this isn't done the USB frames aren't formatted correctly and, for example, the USB3 ethernet ax88179_178a card will stop sending (while still receiving) when running a netperf tcp transmit test with (say) and 8k buffer. This should be a candidate for stable, the ax88179_178a driver defaults to gso and tso enabled so it passes a lot of fragmented skb to the USB stack. Notes from Sarah: Discussion: http://marc.info/?l=linux-usb&m=138384509604981&w=2 This patch fixes a long-standing xHCI driver bug that was revealed by a change in 3.12 in the usb-net driver.

efivars, efi-pstore: Hold off deletion of sysfs entry until the scan is completed
Currently, when mounting pstore file system, a read callback of efi_pstore driver runs mutiple times as below. - In the first read callback, scan efivar_sysfs_list from head and pass a kmsg buffer of a entry to an upper pstore layer. - In the second read callback, rescan efivar_sysfs_list from the entry and pass another kmsg buffer to it. - Repeat the scan and pass until the end of efivar_sysfs_list. In this process, an entry is read across the multiple read function calls. To avoid race between the read and erasion, the whole process above is protected by a spinlock, holding in open() and releasing in close(). At the same time, kmemdup() is called to pass the buffer to pstore filesystem during it. And then, it causes a following lockdep warning. To make the dynamic memory allocation runnable without taking spinlock, holding off a deletion of sysfs entry if it happens while scanning it via efi_pstore, and deleting it after the scan is completed. To implement it, this patch introduces two flags, scanning and deleting, to efivar_entry. On the code basis, it seems that all the scanning and deleting logic is not needed because __efivars->lock are not dropped when reading from the EFI variable store. But, the scanning and deleting logic is still needed because an efi-pstore and a pstore filesystem works as follows. In case an entry(A) is found, the pointer is saved to psi->data. And efi_pstore_read() passes the entry(A) to a pstore filesystem by releasing __efivars->lock. And then, the pstore filesystem calls efi_pstore_read() again and the same entry(A), which is saved to psi->data, is used for resuming to scan a sysfs-list. So, to protect the entry(A), the logic is needed.

cpufreq: suspend governors on system suspend/hibernate
This patch adds cpufreq suspend/resume calls to dpm_{suspend|resume}_noirq()
for handling suspend/resume of cpufreq governors.
Lan Tianyu (Intel) & Jinhyuk Choi (Broadcom) found anr issue where
tunables configuration for clusters/sockets with non-boot CPUs was
getting lost after suspend/resume, as we were notifying governors
with CPUFREQ_GOV_POLICY_EXIT on removal of the last cpu for that
policy and so deallocating memory for tunables. This is fixed by
this patch as we don't allow any operation on governors after
device suspend and before device resume now.

ARM: SoC fixes for 3.13-rc
Mostly bugfixes and a few small code removals. Worth pointing out is:
- A handful of more fixes to get DT enablement working properly on OMAP,
finding new breakage of things that don't work quite right yet without
the traditional board files. I expect a bit more of this to come in this
release as people test on their hardware.
- Implementation of power_down_finish() on vexpress, to make kexec work and
to stop the MCPM core to produce a warning (the warning was new to 3.13-rc1).
- A handful of minor fixes for various platforms.

First round of fixes for IIO in the 3.13 cycle.
The usual mixed bag of fixes. * 3 cases where kconfig dependencies were missing. We need to keep a closer eye on this in new drivers. * hid_sensors was abusing the iio_dev->trigger pointer. We had a round of clearing this out some time ago but this driver clearly slipped through. * A misuse of the IIO_ST macro, in mcp3422, which we should really make a concertive effort to finish removing. * Avoid a double free introduced by recent buffer reference counting in the one driver that (quite reasonably!) does things differently (am335x) * A missing mutex_unlock in kxsd9 that means that driver has been non functional for some time and no one noticed (including me who for once actually has one of the supported devices). * An incorrect assumption about the parameters of sign_extend32 in mcp3422. So nothing controversial. The only substantial patch is the hid_sensors one and that is actually just adding a new pointer to the devices private state then moving the code over to it. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQIcBAABAgAGBQJSk7SvAAoJEFSFNJnE9BaIRNsQAJnM/WiH1ghfA5nuc0V7JrnB 2Z6Qtm3Stoq4Ul5LYiEMxumo6ckL17YFddxejUF9X4Eq5N8YyAxdPd8JdDJgS2OL yCM2x6izd9drIGA3YUMMOvZ1BScSK1e5DmXJHp4nuF68uHtf2TM4TGF/2zuqt3TN 2bL7blNF3/5O/TiBRB4XjkH4Sy5c4G2kke+0SckRnWohTn8oE7tWihr84nYPciqt mu11Nrv9S+sr/5GzRwN8d5SU33yU2/ML32QU/4oQzb/XxBW0W759NJflqY5sSZ89 JQnHcCKKZD7IWBFT0VAMiuEjBpSRGc4vxBbYjsVHtEHzW7v3L0fvob5YqfSrzMlD rVUiTQJm7fC/4hn7iJUPrxkWsSGsjCvVrLZmZFOK3OYONUfd+Cqg0nliihRZo65s 054/yi4v8xd6OUzqSxtWKIK/ZQjDxa5W2BlRoryShCrUAo/e3Djy+jH32v4Mmgfe D9aEwdUqa8kPlq6pyQC2QRgWWU1K5+RRrzW5nNNLlmjYtVlfF+8OgcQYGHW8iMur 8AaDXNZwQLEYA4409T/Ar9lNg4gDqc0YZsvNibu0q4Kxfp13dJOwra+xmF+ktECr KcIFxu5v89SgpE1Rra74OXYFWQ1I4Qy+sJxhQKymthPzmw4nuUidK33mxjtcojwz TvQJu8f3us8Ea5vQLZo0 =cIMc -----END PGP SIGNATURE----- Merge tag 'fixes-for-3.13a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus Jonathan writes: First round of fixes for IIO in the 3.13 cycle.

gpiolib: use dedicated flags for GPIO properties
GPIO mapping properties were defined using the GPIOF_* flags, which are declared in linux/gpio.h. This file is not included when using the GPIO descriptor interface. This patch declares the flags that can be used as GPIO mappings properties in linux/gpio/driver.h, and uses them in gpiolib, so that no deprecated declarations are used by the GPIO descriptor interface. This patch also allows GPIO_OPEN_DRAIN and GPIO_OPEN_SOURCE to be specified as GPIO mapping properties.

Merge branch 'for-linus2' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security
Pull security subsystem updates from James Morris:
"In this patchset, we finally get an SELinux update, with Paul Moore
taking over as maintainer of that code.
Also a significant update for the Keys subsystem, as well as
maintenance updates to Smack, IMA, TPM, and Apparmor"
and since I wanted to know more about the updates to key handling,
here's the explanation from David Howells on that:
"Okay. There are a number of separate bits. I'll go over the big bits
and the odd important other bit, most of the smaller bits are just
fixes and cleanups. If you want the small bits accounting for, I can
do that too.
(1) Keyring capacity expansion.
KEYS: Consolidate the concept of an 'index key' for key access
KEYS: Introduce a search context structure
KEYS: Search for auth-key by name rather than target key ID
Add a generic associative array implementation.
KEYS: Expand the capacity of a keyring
Several of the patches are providing an expansion of the capacity of a
keyring. Currently, the maximum size of a keyring payload is one page.
Subtract a small header and then divide up into pointers, that only gives
you ~500 pointers on an x86_64 box. However, since the NFS idmapper uses
a keyring to store ID mapping data, that has proven to be insufficient to
the cause.
Whatever data structure I use to handle the keyring payload, it can only
store pointers to keys, not the keys themselves because several keyrings
may point to a single key. This precludes inserting, say, and rb_node
struct into the key struct for this purpose.
I could make an rbtree of records such that each record has an rb_node
and a key pointer, but that would use four words of space per key stored
in the keyring. It would, however, be able to use much existing code.
I selected instead a non-rebalancing radix-tree type approach as that
could have a better space-used/key-pointer ratio. I could have used the
radix tree implementation that we already have and insert keys into it by
their serial numbers, but that means any sort of search must iterate over
the whole radix tree. Further, its nodes are a bit on the capacious side
for what I want - especially given that key serial numbers are randomly
allocated, thus leaving a lot of empty space in the tree.
So what I have is an associative array that internally is a radix-tree
with 16 pointers per node where the index key is constructed from the key
type pointer and the key description. This means that an exact lookup by
type+description is very fast as this tells us how to navigate directly to
the target key.
I made the data structure general in lib/assoc_array.c as far as it is
concerned, its index key is just a sequence of bits that leads to a
pointer. It's possible that someone else will be able to make use of it
also. FS-Cache might, for example.
(2) Mark keys as 'trusted' and keyrings as 'trusted only'.
KEYS: verify a certificate is signed by a 'trusted' key
KEYS: Make the system 'trusted' keyring viewable by userspace
KEYS: Add a 'trusted' flag and a 'trusted only' flag
KEYS: Separate the kernel signature checking keyring from module signing
These patches allow keys carrying asymmetric public keys to be marked as
being 'trusted' and allow keyrings to be marked as only permitting the
addition or linkage of trusted keys.
Keys loaded from hardware during kernel boot or compiled into the kernel
during build are marked as being trusted automatically. New keys can be
loaded at runtime with add_key(). They are checked against the system
keyring contents and if their signatures can be validated with keys that
are already marked trusted, then they are marked trusted also and can
thus be added into the master keyring.
Patches from Mimi Zohar make this usable with the IMA keyrings also.
(3) Remove the date checks on the key used to validate a module signature.
X.509: Remove certificate date checks
It's not reasonable to reject a signature just because the key that it was
generated with is no longer valid datewise - especially if the kernel
hasn't yet managed to set the system clock when the first module is
loaded - so just remove those checks.
(4) Make it simpler to deal with additional X.509 being loaded into the kernel.
KEYS: Load *.x509 files into kernel keyring
KEYS: Have make canonicalise the paths of the X.509 certs better to deduplicate
The builder of the kernel now just places files with the extension ".x509"
into the kernel source or build trees and they're concatenated by the
kernel build and stuffed into the appropriate section.
(5) Add support for userspace kerberos to use keyrings.
KEYS: Add per-user_namespace registers for persistent per-UID kerberos caches
KEYS: Implement a big key type that can save to tmpfs
Fedora went to, by default, storing kerberos tickets and tokens in tmpfs.
We looked at storing it in keyrings instead as that confers certain
advantages such as tickets being automatically deleted after a certain
amount of time and the ability for the kernel to get at these tokens more
easily.
To make this work, two things were needed:
(a) A way for the tickets to persist beyond the lifetime of all a user's
sessions so that cron-driven processes can still use them.
The problem is that a user's session keyrings are deleted when the
session that spawned them logs out and the user's user keyring is
deleted when the UID is deleted (typically when the last log out
happens), so neither of these places is suitable.
I've added a system keyring into which a 'persistent' keyring is
created for each UID on request. Each time a user requests their
persistent keyring, the expiry time on it is set anew. If the user
doesn't ask for it for, say, three days, the keyring is automatically
expired and garbage collected using the existing gc. All the kerberos
tokens it held are then also gc'd.
(b) A key type that can hold really big tickets (up to 1MB in size).
The problem is that Active Directory can return huge tickets with lots
of auxiliary data attached. We don't, however, want to eat up huge
tracts of unswappable kernel space for this, so if the ticket is
greater than a certain size, we create a swappable shmem file and dump
the contents in there and just live with the fact we then have an
inode and a dentry overhead. If the ticket is smaller than that, we
slap it in a kmalloc()'d buffer"

mm: thp: give transparent hugepage code a separate copy_page
Right now, the migration code in migrate_page_copy() uses copy_huge_page()
for hugetlbfs and thp pages:
if (PageHuge(page) || PageTransHuge(page))
copy_huge_page(newpage, page);
So, yay for code reuse. But:
void copy_huge_page(struct page *dst, struct page *src)
{
struct hstate *h = page_hstate(src);
and a non-hugetlbfs page has no page_hstate(). This works 99% of the
time because page_hstate() determines the hstate from the page order
alone. Since the page order of a THP page matches the default hugetlbfs
page order, it works.
But, if you change the default huge page size on the boot command-line
(say default_hugepagesz=1G), then we might not even *have* a 2MB hstate
so page_hstate() returns null and copy_huge_page() oopses pretty fast
since copy_huge_page() dereferences the hstate:
void copy_huge_page(struct page *dst, struct page *src)
{
struct hstate *h = page_hstate(src);
if (unlikely(pages_per_huge_page(h) > MAX_ORDER_NR_PAGES)) {
...
Mel noticed that the migration code is really the only user of these
functions. This moves all the copy code over to migrate.c and makes
copy_huge_page() work for THP by checking for it explicitly.
I believe the bug was introduced in commit

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.

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.)

NFS: Enabling v4.2 should not recompile nfsd and lockd
