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.

SCSI fixes on 20131206
This is a set of nine fixes (and one author update). The libsas one should fix discovery in eSATA devices, the WRITE_SAME one is the largest, but it should fix a lot of problems we've been getting with the emulated RAID devices (they've been effectively lying about support and then firmware has been choking on the commands). The rest are various crash, hang or warn driver fixes.

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.

Pull x86 and EFI fixes from Peter Anvin: "Half of these are EFI-related: The by far biggest change is the change to hold off the deletion of a sysfs entry while a backend scan is in progress. This is to avoid calling kmemdup() while under a spinlock. The other major change is for each entry in the EFI pstore backend to get a unique identifier, as required by the pstore filesystem proper. 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.

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.

Pull networking updates from David Miller:
"Here is a pile of bug fixes that accumulated while I was in Europe"
1) In fixing kernel leaks to userspace during copying of socket
addresses, we broke a case that used to work, namely the user
providing a buffer larger than the in-kernel generic socket address
structure. This broke Ruby amongst other things. Fix from Dan
Carpenter.
2) Fix regression added by byte queue limit support in 8139cp driver,
from Yang Yingliang.
3) The addition of MSG_SENDPAGE_NOTLAST buggered up a few sendpage
implementations, they should just treat it the same as MSG_MORE.
Fix from Richard Weinberger and Shawn Landden.
4) Handle icmpv4 errors received on ipv6 SIT tunnels correctly, from
Oussama Ghorbel. In particular we should send an ICMPv6 unreachable
in such situations.
5) Fix some regressions in the recent genetlink fixes, in particular
get the pmcraid driver to use the new safer interfaces correctly.
From Johannes Berg.
6) macvtap was converted to use a per-cpu set of statistics, but some
code was still bumping tx_dropped elsewhere. From Jason Wang.
7) Fix build failure of xen-netback due to missing include on some
architectures, from Andy Whitecroft.
8) macvtap double counts received packets in statistics, fix from Vlad
Yasevich.
9) Fix various cases of using *_STATS_BH() when *_STATS() is more
appropriate. From Eric Dumazet and Hannes Frederic Sowa.
10) Pktgen ipsec mode doesn't update the ipv4 header length and checksum
properly after encapsulation. Fix from Fan Du.

[SCSI] Disable WRITE SAME for RAID and virtual host adapter drivers
Some host adapters do not pass commands through to the target disk directly. Instead they provide an emulated target which may or may not accurately report its capabilities. In some cases the physical device characteristics are reported even when the host adapter is processing commands on the device's behalf. This can lead to adapter firmware hangs or excessive I/O errors. This patch disables WRITE SAME for devices connected to host adapters that provide an emulated target. Driver writers can disable WRITE SAME by setting the no_write_same flag in the host adapter template. [jejb: fix up rejections due to eh_deadline patch] Signed-off-by: Martin K.

genetlink/pmcraid: use proper genetlink multicast API
The pmcraid driver 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 it use the correct API, but since this may already be used as-is by userspace, reserve a family ID for this code and also reserve that group ID to not break userspace assumptions. My previous patch broke event delivery in the driver as I missed that it wasn't using the right API and forgot to update it later in my series. While changing this, I noticed that the genetlink code could use the static group ID instead of a strcmp(), so also do that for the VFS_DQUOT family.

The first netlink attribute (value 0) must always be defined as none/unspec. This is correctly done in inet_diag.h, but other diag interfaces are wrong.

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.

crypto: scatterwalk - Set the chain pointer indication bit
The scatterwalk_crypto_chain function invokes the scatterwalk_sg_chain function to chain two scatterlists, but the chain pointer indication bit is not set. When the resulting scatterlist is used, for example, by sg_nents to count the number of scatterlist entries, a segfault occurs because sg_nents does not follow the chain pointer to the chained scatterlist. Update scatterwalk_sg_chain to set the chain pointer indication bit as is done by the sg_chain function.

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.

This includes two fixes.
1) is a bug fix that happens when root does the following:
echo function_graph > current_tracer
modprobe foo
echo nop > current_tracer
This causes the ftrace internal accounting to get screwed up and
crashes ftrace, preventing the user from using the function tracer
after that.
2) if a TRACE_EVENT has a string field, and NULL is given for it.

"This includes two fixes.
1) is a bug fix that happens when root does the following:
echo function_graph > current_tracer
modprobe foo
echo nop > current_tracer
This causes the ftrace internal accounting to get screwed up and
crashes ftrace, preventing the user from using the function tracer
after that.
2) if a TRACE_EVENT has a string field, and NULL is given for it.

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.

New tracepoints have been added that have allowed for NULL pointers
being assigned to strings. To fix this, change the TRACE_EVENT() code
to check for NULL and if it is, it will assign "(null)" to it instead
(similar to what glibc printf does).

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.

ASoC: dapm: Use SND_SOC_DAPM_INIT_REG_VAL in SND_SOC_DAPM_MUX
SND_SOC_DAPM_MUX() doesn't currently initialize the .mask field. This
results in the mux never affecting HW, since no bits are ever set or
cleared. Fix SND_SOC_DAPM_MUX() to use SND_SOC_DAPM_INIT_REG_VAL() to
set up the reg, shift, on_val, and off_val fields like almost all other
SND_SOC_xxx() macros. It looks like this was a "typo" in the fixed
commit linked below.
This makes the speakers on the Toshiba AC100 (PAZ00) laptop work again.

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"
