Pull NVMe update from Matthew Wilcox: "Mostly bugfixes again for the NVMe driver. I'd like to call out the exported tracepoint in the block layer; I believe Keith has cleared this with Jens. We've had a few reports from people who're really pounding on NVMe devices at scale, hence the timeout changes (and new module parameters), hotplug cpu deadlock, tracepoints, and minor performance tweaks" [ Jens hadn't seen that tracepoint thing, but is ok with it - it will end up going away when mq conversion happens ] * git://git.infradead.org/users/willy/linux-nvme: (22 commits) NVMe: Fix START_STOP_UNIT Scsi->NVMe translation.

btrfs: new ioctl TREE_SEARCH_V2
This new ioctl call allows the user to supply a buffer of varying size in which a tree search can store its results. This is much more flexible if you want to receive items which are larger than the current fixed buffer of 3992 bytes or if you want to fetch more items at once. Items larger than this buffer are for example some of the type EXTENT_CSUM.

ALSA: compress: Cancel the optimization of compiler and fix the size of struct for all platform.
Cancel the optimization of compiler for struct snd_compr_avail which size will be 0x1c in 32bit kernel while 0x20 in 64bit kernel under the optimizer. That will make compaction between 32bit and 64bit. So add packed to fix the size of struct snd_compr_avail to 0x1c for all platform.

Pull nfsd updates from Bruce Fields:
"The largest piece is a long-overdue rewrite of the xdr code to remove
some annoying limitations: for example, there was no way to return
ACLs larger than 4K, and readdir results were returned only in 4k
chunks, limiting performance on large directories.
Also:
- part of Neil Brown's work to make NFS work reliably over the
loopback interface (so client and server can run on the same
machine without deadlocks). The rest of it is coming through
other trees.
- cleanup and bugfixes for some of the server RDMA code, from
Steve Wise.
- Various cleanup of NFSv4 state code in preparation for an
overhaul of the locking, from Jeff, Trond, and Benny.
- smaller bugfixes and cleanup from Christoph Hellwig and

RDMA/core: Add support for iWARP Port Mapper user space service
This patch adds iWARP Port Mapper (IWPM) Version 2 support. The iWARP Port Mapper implementation is based on the port mapper specification section in the Sockets Direct Protocol paper - http://www.rdmaconsortium.org/home/draft-pinkerton-iwarp-sdp-v1.0.pdf Existing iWARP RDMA providers use the same IP address as the native TCP/IP stack when creating RDMA connections. They need a mechanism to claim the TCP ports used for RDMA connections to prevent TCP port collisions when other host applications use TCP ports. The iWARP Port Mapper provides a standard mechanism to accomplish this. Without this service it is possible for RDMA application to bind/listen on the same port which is already being used by native TCP host application. If that happens the incoming TCP connection data can be passed to the RDMA stack with error. The iWARP Port Mapper solution doesn't contain any changes to the existing network stack in the kernel space. All the changes are contained with the infiniband tree and also in user space. The iWARP Port Mapper service is implemented as a user space daemon process. Source for the IWPM service is located at http://git.openfabrics.org/git?p=~tnikolova/libiwpm-1.0.0/.git;a=summary The iWARP driver (port mapper client) sends to the IWPM service the local IP address and TCP port it has received from the RDMA application, when starting a connection. The IWPM service performs a socket bind from user space to get an available TCP port, called a mapped port, and communicates it back to the client. In that sense, the IWPM service is used to map the TCP port, which the RDMA application uses to any port available from the host TCP port space. The mapped ports are used in iWARP RDMA connections to avoid collisions with native TCP stack which is aware that these ports are taken. When an RDMA connection using a mapped port is terminated, the client notifies the IWPM service, which then releases the TCP port. The message exchange between the IWPM service and the iWARP drivers (between user space and kernel space) is implemented using netlink sockets. 1) Netlink interface functions are added: ibnl_unicast() and ibnl_mulitcast() for sending netlink messages to user space 2) The signature of the existing ibnl_put_msg() is changed to be more generic 3) Two netlink clients are added: RDMA_NL_NES, RDMA_NL_C4IW corresponding to the two iWarp drivers - nes and cxgb4 which use the IWPM service 4) Enums are added to enumerate the attributes in the netlink messages, which are exchanged between the user space IWPM service and the iWARP drivers Signed-off-by: Tatyana Nikolova <tatyana.e.nikolova@intel.com> Signed-off-by: Steve Wise <swise@opengridcomputing.com> Reviewed-by: PJ Waskiewicz <pj.waskiewicz@solidfire.com> [ Fold in range checking fixes and nlh_next removal as suggested by Dan Carpenter and Steve Wise.

btrfs: balance filter: add limit of processed chunks
This started as debugging helper, to watch the effects of converting between raid levels on multiple devices, but could be useful standalone. In my case the usage filter was not finegrained enough and led to converting too many chunks at once. Another example use is in connection with drange+devid or vrange filters that allow to work with a specific chunk or even with a chunk on a given device. The limit filter applies last, the value of 0 means no limiting.

ipc/shm.c: increase the defaults for SHMALL, SHMMAX
System V shared memory
a) can be abused to trigger out-of-memory conditions and the standard
measures against out-of-memory do not work:
- it is not possible to use setrlimit to limit the size of shm segments.
- segments can exist without association with any processes, thus
the oom-killer is unable to free that memory.
b) is typically used for shared information - today often multiple GB.
(e.g. database shared buffers)
The current default is a maximum segment size of 32 MB and a maximum
total size of 8 GB. This is often too much for a) and not enough for
b), which means that lots of users must change the defaults.
This patch increases the default limits (nearly) to the maximum, which
is perfect for case b). The defaults are used after boot and as the
initial value for each new namespace.
Admins/distros that need a protection against a) should reduce the
limits and/or enable shm_rmid_forced.
Unix has historically required setting these limits for shared memory,
and Linux inherited such behavior. The consequence of this is added
complexity for users and administrators. One very common example are
Database setup/installation documents and scripts, where users must
manually calculate the values for these limits. This also requires
(some) knowledge of how the underlying memory management works, thus
causing, in many occasions, the limits to just be flat out wrong.
Disabling these limits sooner could have saved companies a lot of time,
headaches and money for support. But it's never too late, simplify
users life now.
Further notes:
- The patch only changes default, overrides behave as before:
# sysctl kernel.shmall=33554432
would recreate the previous limit for SHMMAX (for the current namespace).
- Disabling sysv shm allocation is possible with:
# sysctl kernel.shmall=0
(not a new feature, also per-namespace)
- The limits are intentionally set to a value slightly less than ULONG_MAX,
to avoid triggering overflows in user space apps.

perf: Differentiate exec() and non-exec() comm events
perf tools like 'perf report' can aggregate samples by comm strings, which generally works. However, there are other potential use-cases. For example, to pair up 'calls' with 'returns' accurately (from branch events like Intel BTS) it is necessary to identify whether the process has exec'd. Although a comm event is generated when an 'exec' happens it is also generated whenever the comm string is changed on a whim (e.g. by prctl PR_SET_NAME). This patch adds a flag to the comm event to differentiate one case from the other. In order to determine whether the kernel supports the new flag, a selection bit named 'exec' is added to struct perf_event_attr. The bit does nothing but will cause perf_event_open() to fail if the bit is set on kernels that do not have it defined.

At over 200 commits, covering almost all supported architectures, this
was a pretty active cycle for KVM. Changes include:
- a lot of s390 changes: optimizations, support for migration,
GDB support and more
- ARM changes are pretty small: support for the PSCI 0.2 hypercall
interface on both the guest and the host (the latter acked by Catalin)
- initial POWER8 and little-endian host support
- support for running u-boot on embedded POWER targets
- pretty large changes to MIPS too, completing the userspace interface
and improving the handling of virtualized timer hardware
- for x86, a larger set of changes is scheduled for 3.17. Still,
we have a few emulator bugfixes and support for running nested
fully-virtualized Xen guests (para-virtualized Xen guests have
always worked). And some optimizations too.
The only missing architecture here is ia64. It's not a coincidence
that support for KVM on ia64 is scheduled for removal in 3.17.

Pull KVM updates from Paolo Bonzini:
"At over 200 commits, covering almost all supported architectures, this
was a pretty active cycle for KVM. Changes include:
- a lot of s390 changes: optimizations, support for migration, GDB
support and more
- ARM changes are pretty small: support for the PSCI 0.2 hypercall
interface on both the guest and the host (the latter acked by
Catalin)
- initial POWER8 and little-endian host support
- support for running u-boot on embedded POWER targets
- pretty large changes to MIPS too, completing the userspace
interface and improving the handling of virtualized timer hardware
- for x86, a larger set of changes is scheduled for 3.17. Still, we
have a few emulator bugfixes and support for running nested
fully-virtualized Xen guests (para-virtualized Xen guests have
always worked). And some optimizations too.
The only missing architecture here is ia64. It's not a coincidence
that support for KVM on ia64 is scheduled for removal in 3.17"

This must be about the smallest merge window patch set ever for GFS2.
It is probably also the first one without a single patch from me. That is down to a combination of factors, and I have some things in the works that are not quite ready yet, that I hope to put in next time around. Returning to what is here this time... we have 3 patches which fix various warnings. Two are bug fixes (for quotas and also a rare recovery race condition). The final patch, from Ben Marzinski, is an important change in the freeze code which has been in progress for some time. This removes the need to take and drop the transaction lock for every single transaction, when the only time it was used, was at file system freeze time. Ben's patch integrates the freeze operation into the journal flush code as an alternative with lower overheads and also lands up resolving some difficult to fix races at the same time. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.15 (GNU/Linux) iQIcBAABAgAGBQJTjawdAAoJEMrg3m4a/8jS+fEP/19pd9norrPgt+INKeWF3Nlj 0cCVyivBjjEOQseiokbn6AlO9sIBETCMsd3v/ke8haleR8J6F1K8OvRY2LV76vZT SKTae4Lts7Pzbf8JF9wSi3mpr3zhtQ47v6DvRYEylc68HcwM4EybaSKWEX3By2zd Xmhlv+v7V+PRYthaMalOXjhzuYA4Sv2BgdUGG9xKtIfzjvhHhzws/xBcr9UrotX2 oPjq08X9HY1TNuWN8tTs4P7BrOx8QCb7ZJzT2A9girFyVXNiduGTd11mzCguvHVQ /Ove3/7Cg3fABMg/3Ub2dpARqYxJRV25FlTV8RrOWj0BMhndWAbzMt1KPexk4FAE a3KCMBbo8WZbjRmOB4tmfknxDCdeUDAIlm1mwDPFJ1/0Vv8rkove1+xWHDvOPWD3 219GLiUe7PyVowBW4FQhW+CTjArqz3TWB+R/US18rXcwDS9s/vEIDVVwNYlrxRmK pztGMr25UoFhbvMe3jtu5xRwQM5oZfQtlYdL09+0BgkgPmuOtEwzuopa7g5MBAze Xq7h+oN8M4AtJs/msBF3di+fgOhUyoJmj129xgoZeCxbe80nA0ge0hnb93vQJHmE uHe4zV26ChGjUtxUwf77xOZfCEWKsp1ORJkFN+2SMcpUIlfNNumBv/UhrVRN55AO CneZaFLboYhxqc28K+Ms =x9iK -----END PGP SIGNATURE----- Merge tag 'gfs2-merge-window' of git://git.kernel.org/pub/scm/linux/kernel/git/steve/gfs2-3.0-nmw into next Pull gfs2 updates from Steven Whitehouse: "This must be about the smallest merge window patch set ever for GFS2.

Pull request: Fixes for new ethtool RSS commands
This addresses several problems I previously identified with the new
ETHTOOL_{G,S}RSSH commands:
1. Missing validation of reserved parameters
2. Vague documentation
3. Use of unnamed magic number
4. No consolidation with existing driver operations
I don't currently have access to suitable network hardware, but have
tested these changes with a dummy driver that can support various
combinations of operations and sizes, together with (a) Debian's ethtool
3.13 (b) ethtool 3.14 with the submitted patch to use ETHTOOL_{G,S}RSSH
and minor adjustment for fixes 1 and 3.

bridge: Add bridge ifindex to bridge fdb notify msgs
(This patch was previously posted as RFC at http://patchwork.ozlabs.org/patch/352677/) This patch adds NDA_MASTER attribute to neighbour attributes enum for bridge/master ifindex. And adds NDA_MASTER to bridge fdb notify msgs. Today bridge fdb notifications dont contain bridge information. Userspace can derive it from the port information in the fdb notification. However this is tricky in some scenarious. Example, bridge port delete notification comes before bridge fdb delete notifications. And we have seen problems in userspace when using libnl where, the bridge fdb delete notification handling code does not understand which bridge this fdb entry is part of because the bridge and port association has already been deleted. And these notifications (port membership and fdb) are generated on separate rtnl groups. Fixing the order of notifications could possibly solve the problem for some cases (I can submit a separate patch for that). This patch chooses to add NDA_MASTER to bridge fdb notify msgs because it not only solves the problem described above, but also helps userspace avoid another lookup into link msgs to derive the master index.

Chances are immensely high it would trip over and break. So add a new CAP that gives user space a hint that we have workarounds for the bugs above in place. It can use those as hint to disable PV hypercalls when the guest CPU is anything POWER7 or higher and the host does not have fixes in place. Signed-off-by: Alexander Graf <agraf@suse.de> |
