2014-04-27FDDI: Reformat <linux/if_fddi.h> for 8-character tabsMaciej W. Rozycki
Some of our FDDI support code has been apparently written with an assumption that tabs are 4-character wide. In preparation to the next change this update reformats <linux/if_fddi.h> so that it stays within 79 columns and otherwise renders correctly with 8-character tabs. No functional change.

2014-04-26tipc: add ioctl to fetch link namesErik Hugne
We add a new ioctl for AF_TIPC that can be used to fetch the logical name for a link to a remote node on a given bearer. This should be used in combination with link state subscriptions. The logical name size limit definitions are moved to tipc.h, as they are now also needed by the new ioctl.

2014-04-25cfg80211: Add attributes describing prohibited channel bandwidthRostislav Lisovy
Since there are frequency bands (e.g. 5.9GHz) allowing channels with only 10 or 5 MHz bandwidth, this patch adds attributes that allow keeping track about this information. When channel attributes are reported to user-space, make sure to not break old tools, i.e. if the 'split wiphy dump' is enabled, report the extra attributes (if present) describing the bandwidth restrictions. If the 'split wiphy dump' is not enabled, completely omit those channels that have flags set to either IEEE80211_CHAN_NO_10MHZ or IEEE80211_CHAN_NO_20MHZ.

Add a netlink multicast socket with one group to kaudit for "best-effort" delivery to read-only userspace clients such as systemd, in addition to the existing bidirectional unicast auditd userspace client. Currently, auditd is intended to use the CAP_AUDIT_CONTROL and CAP_AUDIT_WRITE capabilities, but actually uses CAP_NET_ADMIN. The CAP_AUDIT_READ capability is added for use by read-only AUDIT_NLGRP_READLOG netlink multicast group clients to the kaudit subsystem.

Newer Linux versions also do not use the storage keys for dirty and reference tracking. We can optimize the guest handling for those guests for faults as well as page-in and page-out by simply not caring about the guest visible storage key. We trap guest storage key instruction to enable those keys only on demand. Migration bitmap Until now s390 never provided a proper dirty bitmap. Let's provide a proper migration bitmap for s390. We also change the user dirty tracking to a fault based mechanism. This makes the host completely independent from the storage keys.

Userspace controlled CMMA ------------------------- The CMMA assist is changed from "always on" to "on if requested" via per-VM device attributes. In addition a callback to reset all usage states is provided. Proper guest DAT handling for intercepts ---------------------------------------- While instructions handled by SIE take care of all addressing aspects, KVM/s390 currently does not care about guest address translation of intercepts. This worked out fine, because - the s390 Linux kernel has a 1:1 mapping between kernel virtual<->real for all pages up to memory size - intercepts happen only for a small amount of cases - all of these intercepts happen to be in the kernel text for current distros Of course we need to be better for other intercepts, kernel modules etc. We provide the infrastructure and rework all in-kernel intercepts to work on logical addresses (paging etc) instead of real ones. The code has been running internally for several months now, so it is time for going public. GDB support ----------- We provide breakpoints, single stepping and watchpoints.

2014-04-22locks: rename file-private locks to "open file description locks"Jeff Layton
File-private locks have been merged into Linux for v3.15, and *now* people are commenting that the name and macro definitions for the new file-private locks suck. ...and I can't even disagree. The names and command macros do suck. We're going to have to live with these for a long time, so it's important that we be happy with the names before we're stuck with them. The consensus on the lists so far is that they should be rechristened as "open file description locks". The name isn't a big deal for the kernel, but the command macros are not visually distinct enough from the traditional POSIX lock macros. The glibc and documentation folks are recommending that we change them to look like F_OFD_{GETLK|SETLK|SETLKW}. That lessens the chance that a programmer will typo one of the commands wrong, and also makes it easier to spot this difference when reading code. This patch makes the following changes that I think are necessary before v3.15 ships: 1) rename the command macros to their new names. These end up in the uapi headers and so are part of the external-facing API. It turns out that glibc doesn't actually use the fcntl.h uapi header, but it's hard to be sure that something else won't. Changing it now is safest. 2) make the the /proc/locks output display these as type "OFDLCK" Cc: Michael Kerrisk <mtk.manpages@gmail.com> Cc: Christoph Hellwig <hch@infradead.org> Cc: Carlos O'Donell <carlos@redhat.com> Cc: Stefan Metzmacher <metze@samba.org> Cc: Andy Lutomirski <luto@amacapital.net> Cc: Frank Filz <ffilzlnx@mindspring.com> Cc: Theodore Ts'o <tytso@mit.edu> Signed-off-by: Jeff Layton <jlayton@redhat.com>

On some newer laptops with a trackpoint the physical buttons for the trackpoint have been removed to allow for a larger touchpad. On these laptops the buttonpad has clearly marked areas on the top which are to be used as trackpad buttons.

2014-04-17KVM: VMX: speed up wildcard MMIO EVENTFDMichael S. Tsirkin
With KVM, MMIO is much slower than PIO, due to the need to do page walk and emulation. But with EPT, it does not have to be: we know the address from the VMCS so if the address is unique, we can look up the eventfd directly, bypassing emulation. Unfortunately, this only works if userspace does not need to match on access length and data. The implementation adds a separate FAST_MMIO bus internally. This serves two purposes: - minimize overhead for old userspace that does not use eventfd with lengtth = 0 - minimize disruption in other code (since we don't know the length, devices on the MMIO bus only get a valid address in write, this way we don't need to touch all devices to teach them to handle an invalid length) At the moment, this optimization only has effect for EPT on x86. It will be possible to speed up MMIO for NPT and MMU using the same idea in the future. With this patch applied, on VMX MMIO EVENTFD is essentially as fast as PIO. I was unable to detect any measureable slowdown to non-eventfd MMIO. Making MMIO faster is important for the upcoming virtio 1.0 which includes an MMIO signalling capability. The idea was suggested by Peter Anvin. Lots of thanks to Gleb for pre-review and suggestions. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
2014-04-17KVM: support any-length wildcard ioeventfdMichael S. Tsirkin
It is sometimes benefitial to ignore IO size, and only match on address. In hindsight this would have been a better default than matching length when KVM_IOEVENTFD_FLAG_DATAMATCH is not set, In particular, this kind of access can be optimized on VMX: there no need to do page lookups. This can currently be done with many ioeventfds but in a suboptimal way. However we can't change kernel/userspace ABI without risk of breaking some applications. Use len = 0 to mean "ignore length for matching" in a more optimal way. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>

2014-04-16drm/tegra: Remove gratuitous pad fieldThierry Reding
The version of the drm_tegra_submit structure that was merged all the way back in 3.10 contains a pad field that was originally intended to properly pad the following __u64 field. Unfortunately it seems like a different field was dropped during review that caused this padding to become unnecessary, but the pad field wasn't removed at that time. One possible side-effect of this is that since the __u64 following the pad is now no longer properly aligned, the compiler may (or may not) introduce padding itself, which results in no predictable ABI. Rectify this by removing the pad field so that all fields are again naturally aligned. Technically this is breaking existing userspace ABI, but given that there aren't any (released) userspace drivers that make use of this yet, the fallout should be minimal.

For commands returned with failed status, queue these for resubmission and continue retrying them until success or for a limited amount of time. The final timeout was arbitrarily chosen so requests can't be retried indefinitely. Since these are requeued on the nvmeq that submitted the command, the callbacks have to take an nvmeq instead of an nvme_dev as a parameter so that we can use the locked queue to append the iod to retry later. The nvme_iod conviently can be used to track how long we've been trying to successfully complete an iod request. The nvme_iod also provides the nvme prp dma mappings, so I had to move a few things around so we can keep those mappings.

When dynamically creating interfaces from userspace, e.g. for P2P usage, such interfaces are usually owned by the process that created them, i.e. wpa_supplicant. Should wpa_supplicant crash, such interfaces will often cease operating properly and cause problems on restarting the process. To avoid this problem, introduce an ownership concept for interfaces. If an interface is owned by a netlink socket, then it will be destroyed if the netlink socket is closed for any reason, including if the process it belongs to crashed.

2014-04-06[media] v4l2-common: fix warning when used on userpaceMauro Carvalho Chehab
As reported by Linus, make headers_check is reporting: usr/include/linux/v4l2-common.h:72: found __[us]{8,16,32,64} type without #include <linux/types.h> which seems to have come in through commits 777f4f85b75f1 and 254a47770163f. That happens because struct v4l2_edid should be visible by both subdev and V4L2 APIs. So, it was moved to v4l2-common.h. As Linus pointed, the proper fix is to just add an include for linux/types.h at v4l2-common.h.

It is good to see that interest is increasing in GFS2, and I'd like to thank all the contributors to this patch set. In addition to the usual set of bug fixes and clean ups, there are patches to improve inode creation performance when xattrs are required and some improvements to the transaction code which is intended to help improve scalability after further changes in due course. Journal extent mapping is also updated to make it more efficient and again, this is a foundation for future work in this area. The maximum number of ACLs has been increased to 300 (for a 4k block size) which means that even with a few additional xattrs from selinux, everything should fit within a single fs block. There is also a patch to bring GFS2's own copy of the writepages code up to the same level as the core VFS. Eventually we may be able to merge some of this code, since it is fairly similar.
