Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs
Pull btrfs update from Chris Mason: "The biggest feature in the pull is the new (and still experimental) raid56 code that David Woodhouse started long ago. I'm still working on the parity logging setup that will avoid inconsistent parity after a crash, so this is only for testing right now. But, I'd really like to get it out to a broader audience to hammer out any performance issues or other problems. scrub does not yet correct errors on raid5/6 either. Josef has another pass at fsync performance. The big change here is to combine waiting for metadata with waiting for data, which is a big latency win. It is also step one toward using atomics from the hardware during a commit. Mark Fasheh has a new way to use btrfs send/receive to send only the metadata changes. SUSE is using this to make snapper more efficient at finding changes between snapshosts. Snapshot-aware defrag is also included. Otherwise we have a large number of fixes and cleanups. Eric Sandeen wins the award for removing the most lines, and I'm hoping we steal this idea from XFS over and over again." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs: (118 commits) btrfs: fixup/remove module.h usage as required Btrfs: delete inline extents when we find them during logging btrfs: try harder to allocate raid56 stripe cache Btrfs: cleanup to make the function btrfs_delalloc_reserve_metadata more logic Btrfs: don't call btrfs_qgroup_free if just btrfs_qgroup_reserve fails Btrfs: remove reduplicate check about root in the function btrfs_clean_quota_tree Btrfs: return ENOMEM rather than use BUG_ON when btrfs_alloc_path fails Btrfs: fix missing deleted items in btrfs_clean_quota_tree btrfs: use only inline_pages from extent buffer Btrfs: fix wrong reserved space when deleting a snapshot/subvolume Btrfs: fix wrong reserved space in qgroup during snap/subv creation Btrfs: remove unnecessary dget_parent/dput when creating the pending snapshot btrfs: remove a printk from scan_one_device Btrfs: fix NULL pointer after aborting a transaction Btrfs: fix memory leak of log roots Btrfs: copy everything if we've created an inline extent btrfs: cleanup for open-coded alignment Btrfs: do not change inode flags in rename Btrfs: use reserved space for creating a snapshot clear chunk_alloc flag on retryable failure ... |

metag: ptrace
The ptrace interface for metag provides access to some core register
sets using the PTRACE_GETREGSET and PTRACE_SETREGSET operations. The
details of the internal context structures is abstracted into user API
structures to both ease use and allow flexibility to change the internal
context layouts. Copyin and copyout functions for these register sets
are exposed to allow signal handling code to use them to copy to and
from the signal context.
struct user_gp_regs (NT_PRSTATUS) provides access to the core general
purpose register context.
struct user_cb_regs (NT_METAG_CBUF) provides access to the TXCATCH*
registers which contains information abuot a memory fault, unaligned
access error or watchpoint. This can be modified to alter the way the
fault is replayed on resume ("catch replay"), or to prevent the replay
taking place.
struct user_rp_state (NT_METAG_RPIPE) provides access to the state of
the Meta read pipeline which can be used to hide memory latencies in
hand optimised data loops.
Extended DSP register state, DSP RAM, and hardware breakpoint registers
aren't yet exposed through ptrace.

dm ioctl: allow message to return data
This patch introduces enhanced message support that allows the device-mapper core to recognise messages that are common to all devices, and for messages to return data to userspace. Core messages are processed by the function "message_for_md". If the device mapper doesn't support the message, it is passed to the target driver. If the message returns data, the kernel sets the flag DM_MESSAGE_OUT_FLAG. Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com> |

dm ioctl: optimize functions without variable params
Device-mapper ioctls receive and send data in a buffer supplied by userspace. The buffer has two parts. The first part contains a 'struct dm_ioctl' and has a fixed size. The second part depends on the ioctl and has a variable size. This patch recognises the specific ioctls that do not use the variable part of the buffer and skips allocating memory for it. In particular, when a device is suspended and a resume ioctl is sent, this now avoid memory allocation completely. The variable "struct dm_ioctl tmp" is moved from the function copy_params to its caller ctl_ioctl and renamed to param_kernel. It is used directly when the ioctl function doesn't need any arguments.

nbd: support FLUSH requests
Currently, the NBD device does not accept flush requests from the Linux block layer. If the NBD server opened the target with neither O_SYNC nor O_DSYNC, however, the device will be effectively backed by a writeback cache. Without issuing flushes properly, operation of the NBD device will not be safe against power losses. The NBD protocol has support for both a cache flush command and a FUA command flag; the server will also pass a flag to note its support for these features. This patch adds support for the cache flush command and flag. In the kernel, we receive the flags via the NBD_SET_FLAGS ioctl, and map NBD_FLAG_SEND_FLUSH to the argument of blk_queue_flush. When the flag is active the block layer will send REQ_FLUSH requests, which we translate to NBD_CMD_FLUSH commands. FUA support is not included in this patch because all free software servers implement it with a full fdatasync; thus it has no advantage over supporting flush only. Because I [Paolo] cannot really benchmark it in a realistic scenario, I cannot tell if it is a good idea or not. It is also not clear if it is valid for an NBD server to support FUA but not flush. The Linux block layer gives a warning for this combination, the NBD protocol documentation says nothing about it. The patch also fixes a small problem in the handling of flags: nbd->flags must be cleared at the end of NBD_DO_IT, but the driver was not doing that. The bug manifests itself as follows. Suppose you two different client/server pairs to start the NBD device. Suppose also that the first client supports NBD_SET_FLAGS, and the first server sends NBD_FLAG_SEND_FLUSH; the second pair instead does neither of these two things. Before this patch, the second invocation of NBD_DO_IT will use a stale value of nbd->flags, and the second server will issue an error every time it receives an NBD_CMD_FLUSH command. This bug is pre-existing, but it becomes much more important after this patch; flush failures make the device pretty much unusable, unlike Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Alex Bligh <alex@alex.org.uk> Acked-by: Paul Clements <Paul.Clements@steeleye.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

fat: mark fs as dirty on mount and clean on umount
There is no documented methods to mark FAT as dirty. Unofficially MS started to use reserved Byte in boot sector for this purpose, at least since Win 2000. With Win 7 user is warned if fs is dirty and asked to clean it. Different versions of Win, handle it in different ways, but always have same meaning: - Win 2000 and XP, set it on write operations and remove it after operation was finnished - Win 7, set dirty flag on first write and remove it on umount. We will do it as follows: - set dirty flag on mount. If fs was initially dirty, warn user, remember it and do not do any changes to boot sector. - clean it on umount. If fs was initially dirty, leave it dirty. - do not do any thing if fs mounted read-only. - TODO: leave fs dirty if we found some error after mount.

It is possible to get or set only these two fields as extended attributes. But HFS+ treats as com.apple.FinderInfo extended attribute an union of user_info and finder_info fields as for file (struct hfsplus_cat_file) as for folder (struct hfsplus_cat_folder). Moreover, current mainline implementation of hfsplus file system driver doesn't support special metadata file - attributes tree. Mac OS X 10.4 and later support extended attributes by making use of the HFS+ filesystem Attributes file B*-tree feature which allows for named forks. Mac OS X supports only inline extended attributes, limiting their size to 3802 bytes. Any regular file may have a list of extended attributes. HFS+ supports an arbitrary number of named forks. Each attribute is denoted by a name and the associated data. The name is a null-terminated Unicode string. It is possible to list, to get, to set, and to remove extended attributes from files or directories. It exists some peculiarity during getting of extended attributes list by means of getfattr utility. The getfattr utility expects prefix "user." before any extended attribute's name. So, it ignores any names that don't contained such prefix. Such behavior of getfattr utility results in unexpected empty output of extended attributes list even in the case when file (or folder) contains extended attributes. It needs to use empty string as regular expression pattern for names matching (getfattr --match=""). For support of extended attributes in HFS+: 1. It was added necessary on-disk layout declarations related to Attributes tree into hfsplus_raw.h file. 2. It was added attributes.c file with implementation of functionality of manipulation by records in Attributes tree. 3. It was reworked hfsplus_listxattr, hfsplus_getxattr, hfsplus_setxattr functions in ioctl.c. Moreover, it was added hfsplus_removexattr method. This patch: Add osx.* prefix for handling namespace of Mac OS X extended attributes.

block: optionally snapshot page contents to provide stable pages during write
This provides a band-aid to provide stable page writes on jbd without needing to backport the fixed locking and page writeback bit handling schemes of jbd2. The band-aid works by using bounce buffers to snapshot page contents instead of waiting. For those wondering about the ext3 bandage -- fixing the jbd locking (which was done as part of ext4dev years ago) is a lot of surgery, and setting PG_writeback on data pages when we actually hold the page lock dropped ext3 performance by nearly an order of magnitude. If we're going to migrate iscsi and raid to use stable page writes, the complaints about high latency will likely return. We might as well centralize their page snapshotting thing to one place.

arm-soc: virtualization changes
This contains parts of the ARM KVM support that have dependencies on other patches merged through the arm-soc tree.

Sound updates for 3.9-rc1
The biggest change in this update is the unification of HD-audio codec parsers. Now the HD-audio codec is parsed in a generic parser code which is invoked by each HD-audio codec driver.

Pull networking update from David Miller:
1) Checkpoint/restarted TCP sockets now can properly propagate the TCP
timestamp offset. From Andrey Vagin.
2) VMWARE VM VSOCK layer, from Andy King.
3) Much improved support for virtual functions and SR-IOV in bnx2x,
from Ariel ELior.
4) All protocols on ipv4 and ipv6 are now network namespace aware, and
all the compatability checks for initial-namespace-only protocols is
removed. Thanks to Tom Parkin for helping deal with the last major
holdout, L2TP.
5) IPV6 support in netpoll and network namespace support in pktgen,
from Cong Wang.
6) Multiple Registration Protocol (MRP) and Multiple VLAN Registration
Protocol (MVRP) support, from David Ward.
7) Compute packet lengths more accurately in the packet scheduler, from
Eric Dumazet.
8) Use per-task page fragment allocator in skb_append_datato_frags(),
also from Eric Dumazet.
9) Add support for connection tracking labels in netfilter, from
Florian Westphal.
10) Fix default multicast group joining on ipv6, and add anti-spoofing
checks to 6to4 and 6rd. From Hannes Frederic Sowa.
11) Make ipv4/ipv6 fragmentation memory limits more reasonable in modern
times, rearrange inet frag datastructures for better cacheline
locality, and move more operations outside of locking. From Jesper
Dangaard Brouer.
12) Instead of strict master <--> slave relationships, allow arbitrary
scenerios with "upper device lists". From Jiri Pirko.
13) Improve rate limiting accuracy in TBF and act_police, also from Jiri
Pirko.
14) Add a BPF filter netfilter match target, from Willem de Bruijn.
15) Orphan and delete a bunch of pre-historic networking drivers from

this still needs some minor bug fixing before it's %100 correct in
all cases.
17) Handle unresolved IPSEC states like ARP, with a resolution packet
queue. From Steffen Klassert.
18) Remove TCP Appropriate Byte Count support (ABC), from Stephen
Hemminger. This was long overdue.

btrfs: add "no file data" flag to btrfs send ioctl
This patch adds the flag, BTRFS_SEND_FLAG_NO_FILE_DATA to the btrfs send ioctl code. When this flag is set, the btrfs send code will never write file data into the stream (thus also avoiding expensive reads of that data in the first place). BTRFS_SEND_C_UPDATE_EXTENT commands will be sent (instead of BTRFS_SEND_C_WRITE) with an offset, length pair indicating the extent in question. This patch does not affect the operation of BTRFS_SEND_C_CLONE commands - they will continue to be sent when a search finds an appropriate extent to clone from.

Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf changes from Ingo Molnar:
"There are lots of improvements, the biggest changes are:
Main kernel side changes:
- Improve uprobes performance by adding 'pre-filtering' support, by
Oleg Nesterov.
- Make some POWER7 events available in sysfs, equivalent to what was
done on x86, from Sukadev Bhattiprolu.
- tracing updates by Steve Rostedt - mostly misc fixes and smaller
improvements.
- Use perf/event tracing to report PCI Express advanced errors, by
Tony Luck.
- Enable northbridge performance counters on AMD family 15h, by Jacob
Shin.
- This tracing commit:
tracing: Remove the extra 4 bytes of padding in events
changes the ABI. All involved parties (PowerTop in particular)
seem to agree that it's safe to do now with the introduction of
libtraceevent, but the devil is in the details ...
Main tooling side changes:
- Add 'event group view', from Namyung Kim:
To use it, 'perf record' should group events when recording. And
then perf report parses the saved group relation from file header
and prints them together if --group option is provided. You can
use the 'perf evlist' command to see event group information:
$ perf record -e '{ref-cycles,cycles}' noploop 1
[ perf record: Woken up 2 times to write data ]
[ perf record: Captured and wrote 0.385 MB perf.data (~16807 samples) ]
$ perf evlist --group
{ref-cycles,cycles}
With this example, default perf report will show you each event
separately.
You can use --group option to enable event group view:
$ perf report --group
...
# group: {ref-cycles,cycles}
# ========
# Samples: 7K of event 'anon group { ref-cycles, cycles }'
# Event count (approx.): 6876107743
#
# Overhead Command Shared Object Symbol
# ................ ....... ................. ..........................
99.84% 99.76% noploop noploop [.] main
0.07% 0.00% noploop ld-2.15.so [.] strcmp
0.03% 0.00% noploop [kernel.kallsyms] [k] timerqueue_del
0.03% 0.03% noploop [kernel.kallsyms] [k] sched_clock_cpu
0.02% 0.00% noploop [kernel.kallsyms] [k] account_user_time
0.01% 0.00% noploop [kernel.kallsyms] [k] __alloc_pages_nodemask
0.00% 0.00% noploop [kernel.kallsyms] [k] native_write_msr_safe
0.00% 0.11% noploop [kernel.kallsyms] [k] _raw_spin_lock
0.00% 0.06% noploop [kernel.kallsyms] [k] find_get_page
0.00% 0.02% noploop [kernel.kallsyms] [k] rcu_check_callbacks
0.00% 0.02% noploop [kernel.kallsyms] [k] __current_kernel_time
As you can see the Overhead column now contains both of ref-cycles
and cycles and header line shows group information also - 'anon
group { ref-cycles, cycles }'. The output is sorted by period of
group leader first.
- Initial GTK+ annotate browser, from Namhyung Kim.
- Add option for runtime switching perf data file in perf report,
just press 's' and a menu with the valid files found in the current
directory will be presented, from Feng Tang.
- Add support to display whole group data for raw columns, from Jiri
Olsa.
- Add per processor socket count aggregation in perf stat, from
Stephane Eranian.
- Add interval printing in 'perf stat', from Stephane Eranian.
- 'perf test' improvements
- Add support for wildcards in tracepoint system name, from Jiri
Olsa.
- Add anonymous huge page recognition, from Joshua Zhu.
- perf build-id cache now can show DSOs present in a perf.data file
that are not in the cache, to integrate with build-id servers being
put in place by organizations such as Fedora.
- perf top now shares more of the evsel config/creation routines with
'record', paving the way for further integration like 'top'
snapshots, etc.
- perf top now supports DWARF callchains.
- Fix mmap limitations on 32-bit, fix from David Miller.
- 'perf bench numa mem' NUMA performance measurement suite
- ... and lots of fixes, performance improvements, cleanups and other
improvements I failed to list - see the shortlog and git log for
details."

Pablo Neira Ayuso says: ==================== The following patchset contain updates for your net-next tree, they are: * Fix (for just added) connlabel dependencies, from Florian Westphal. * Add aliasing support for conntrack, thus users can either use -m state or -m conntrack from iptables while using the same kernel module, from Jozsef Kadlecsik. * Some code refactoring for the CT target to merge common code in revision 0 and 1, from myself. * Add aliasing support for CT, based on patch from Jozsef Kadlecsik. * Add one mutex per nfnetlink subsystem, from myself. * Improved logging for packets that are dropped by helpers, from myself. ==================== Signed-off-by: David S.

Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net into net
Pull in 'net' to take in the bug fixes that didn't make it into 3.8-final. Also, deal with the semantic conflict of the change made to net/ipv6/xfrm6_policy.c A missing rt6->n neighbour release was added to 'net', but in 'net-next' we no longer cache the neighbour entries in the ipv6 routes so that change is not appropriate there.

Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next
John W. Linville says: ==================== This probably is the last big pull request for wireless bits for 3.9. Of course, I'm sure there will be a few stragglers here and there...surely a few bug fixes as well... :-) (In fact, I see that Johannes has already queued-up a few more for me while I was preparing this...) Included are a number of pulls... For mac80211-next, Johannes says: "The biggest change I have is undoubtedly Marco's mesh powersave implementation. Beyond that, I have a patch from Emmanuel to modify the DTIM period API in mac80211, scan improvements and a removal of some previous workaround code from Stanislaw, dynamic short slot time from Thomas and 64-bit station byte counters from Vladimir. I also made a number of changes myself, some related to WoWLAN, some auth/deauth improvements and most of them BSS list cleanups." "This time, I have relatively large number of fixes in various areas of the code (a memory leak in regulatory, an RX race in mac80211, the new radar checking caused a P2P device problem, some mesh issues with stations, an older bug in tracing and for kernel-doc) as well as a number of small new features. The biggest (in the diffstat) is my work on hidden SSID tracking." "Please pull to get * radar detection work from Simon * mesh improvements from Thomas * a connection monitoring/powersave fix from Wojciech * TDLS-related station management work from Jouni * VLAN crypto fixes from Michael Braun * CCK support in minstrel_ht from Felix * an SMPS (not SMSP, oops) related improvement in mac80211 (Emmanuel) * some WoWLAN work from Amitkumar Karwar: pattern match offset and a documentation fix * some WoWLAN work from myself (TCP connection wakeup feature API) * and a lot of VHT (and some HT) work (also from myself) And a number of more random cleanups/fixes. I merged mac80211/master to avoid a merge problem there." And regarding iwlwifi-next, Johannes says: "We continue work on our new driver, but I also have a WoWLAN and AP mode improvement for the previous driver and a change to use threaded interrupts to prepare us for working with non-PCIe devices." Regarding wl12xx, Luca says: "A few more patches intended for 3.9. Mostly some clean-ups I've been doing to make it easier to support device-tree. Also including one bug fix for wl12xx where the rates we advertise were wrong and an update in the wlconf structure to support newer firmwares." For the nfc-next bits, Samuel says: "This is the second NFC pull request for 3.9. We have: - A few pn533 fixes on top of Waldemar refactorization of the driver, one of them fixes target mode. - A new driver for Inside Secure microread chipset. It supports two physical layers: i2c and MEI. The MEI one depends on a patchset that's been sent to Greg Kroah-Hartman for inclusion into the 3.9 kernel [1]. The dependency is a KConfig one which means this code is not buildable as long as the MEI API is not usptream." "This 3rd NFC pull request for 3.9 contains a fix for the microread MEI physical layer support, as the MEI bus API changed. From the MEI code, we now pass the MEI id back to the driver probe routine, and we also pass a name and a MEI id table through the mei_bus_driver structure. A few renames as well like e.g. mei_bus_driver to mei_driver or mei_bus_client to mei_device in order to be closer to the driver model practices." For the ath6kl bits, Kalle says: "There's not anything special here, most of the patches are just code cleanup. The only functional changes are using the beacon interval from user space and fixing a crash which happens when inserting and removing the module in a loop." Also, I pulled the wireless tree in order to resolve some pending merge issues. On top of that, there is a bunch of work on brcmfmac that leads up to P2P support. Also, mwifiex, rtlwifi, and a variety of other drivers see some basic cleanups and minor enhancements. Please let me know if there are problems! ==================== Signed-off-by: David S.

vfio-pci: Add support for VGA region access
PCI defines display class VGA regions at I/O port address 0x3b0, 0x3c0 and MMIO address 0xa0000. As these are non-overlapping, we can ignore the I/O port vs MMIO difference and expose them both in a single region. We make use of the VGA arbiter around each access to configure chipset access as necessary. Signed-off-by: Alex Williamson <alex.williamson@redhat.com> |

drm/omap: move out of staging
Now that the omapdss interface has been reworked so that omapdrm can use dispc directly, we have been able to fix the remaining functional kms issues with omapdrm. And in the mean time the PM sequencing and many other of that open issues have been solved. So I think it makes sense to finally move omapdrm out of staging.

nl80211: renumber NL80211_FEATURE_FULL_AP_CLIENT_STATE
Adding the flag to mac80211 already without testing was clearly a mistake, one that we now pay for by having to reserve bit 13 forever. The problem is cfg80211 doesn't allow capability/rate changes for station entries that were added unassociated, so the station entries cannot be set up properly when marked associated. Change the NL80211_FEATURE_FULL_AP_CLIENT_STATE value to make it clear to userspace implementations that all current kernels don't actually support it, even though the previous bit is set, and of course also remove the flag from mac80211 until we test and fix the issues.

cfg80211: Pass station (extended) capability info to kernel
The information of the peer's capabilities and extended capabilities are required for the driver to perform TDLS Peer UAPSD operations and off channel operations. This information of the peer is passed from user space using NL80211_CMD_SET_STATION command. This commit enhances the function nl80211_set_station to pass the capability information of the peer to the driver. Similarly, there may be need for capability information for other modes, so allow this to be provided with both add_station and change_station.
