* ANDROID: net: core: fix UID-based routingAmit Pundir2016-08-18
| | | | | | | | | | | | | | Fix RTA_UID enum to match it with the Android userspace code which assumes RTA_UID=18. With this patch all Android kernel networking unit tests mentioned here https://source.android.com/devices/tech/config/kernel_network_tests.html are success. Without this patch multinetwork_test.py unit test fails. Change-Id: I3ff36670f7d4e5bf5f01dce584ae9d53deabb3ed Signed-off-by: Amit Pundir <amit.pundir@linaro.org>

| | * | perf/core: adding PMU driver specific configurationMathieu Poirier2016-06-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is entirely possible that some PMUs need specific configuration that is currently not found in the perf options before a session can be setup. It is the case for the CoreSight PMU where a sink needs to be provided. That sink doesn't fall in any of the current perf options. As such this patch adds the capability to receive driver specific configuration using the existing ioctl() mechanism. Once the configuration has been pushed down the kernel PMU callbacks are used to deal with the information sent from user space. Signed-off-by: Mathieu Poirier <mathieu.poirier@linaro.org>

* | ext4: Add support for FIDTRIM, a best-effort ioctl for deep discard trimJP Abgrall2016-02-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * What This provides an interface for issuing an FITRIM which uses the secure discard instead of just a discard. Only the eMMC command is "secure", and not how the FS uses it: due to the fact that the FS might reassign a region somewhere else, the original deleted data will not be affected by the "trim" which only handles un-used regions. So we'll just call it "deep discard", and note that this is a "best effort" cleanup. * Why Once in a while, We want to be able to cleanup most of the unused blocks after erasing a bunch of files. We don't want to constantly secure-discard via a mount option. From an eMMC spec perspective, it tells the device to really get rid of all the data for the specified blocks and not just put them back into the pool of free ones (unlike the normal TRIM). The eMMC spec says the secure trim handling must make sure the data (and metadata) is not available anymore. A simple TRIM doesn't clear the data, it just puts blocks in the free pool. JEDEC Standard No. 84-A441 7.6.9 Secure Erase 7.6.10 Secure Trim From an FS perspective, it is acceptable to leave some data behind. - directory entries related to deleted files - databases entries related to deleted files - small-file data stored in inode extents - blocks held by the FS waiting to be re-used (mitigated by sync). - blocks reassigned by the FS prior to FIDTRIM.

* | mm: add a field to store names for private anonymous memoryColin Cross2016-02-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Userspace processes often have multiple allocators that each do anonymous mmaps to get memory. When examining memory usage of individual processes or systems as a whole, it is useful to be able to break down the various heaps that were allocated by each layer and examine their size, RSS, and physical memory usage. This patch adds a user pointer to the shared union in vm_area_struct that points to a null terminated string inside the user process containing a name for the vma. vmas that point to the same address will be merged, but vmas that point to equivalent strings at different addresses will not be merged. Userspace can set the name for a region of memory by calling prctl(PR_SET_VMA, PR_SET_VMA_ANON_NAME, start, len, (unsigned long)name); Setting the name to NULL clears it. The names of named anonymous vmas are shown in /proc/pid/maps as [anon:<name>] and in /proc/pid/smaps in a new "Name" field that is only present for named vmas. If the userspace pointer is no longer valid all or part of the name will be replaced with "<fault>". The idea to store a userspace pointer to reduce the complexity within mm (at the expense of the complexity of reading /proc/pid/mem) came from Dave Hansen. This results in no runtime overhead in the mm subsystem other than comparing the anon_name pointers when considering vma merging. The pointer is stored in a union with fieds that are only used on file-backed mappings, so it does not increase memory usage. Includes fix from Jed Davis <jld@mozilla.com> for typo in prctl_set_vma_anon_name, which could attempt to set the name across two vmas at the same time due to a typo, which might corrupt the vma list. Fix it to use tmp instead of end to limit the name setting to a single vma at a time. Change-Id: I9aa7b6b5ef536cd780599ba4e2fba8ceebe8b59f Signed-off-by: Dmitry Shmidt <dimitrysh@google.com>

* | net: ipv6: autoconf routes into per-device tablesLorenzo Colitti2016-02-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, IPv6 router discovery always puts routes into RT6_TABLE_MAIN. This causes problems for connection managers that want to support multiple simultaneous network connections and want control over which one is used by default (e.g., wifi and wired). To work around this connection managers typically take the routes they prefer and copy them to static routes with low metrics in the main table. This puts the burden on the connection manager to watch netlink to see if the routes have changed, delete the routes when their lifetime expires, etc. Instead, this patch adds a per-interface sysctl to have the kernel put autoconf routes into different tables. This allows each interface to have its own autoconf table, and choosing the default interface (or using different interfaces at the same time for different types of traffic) can be done using appropriate ip rules. The sysctl behaves as follows: - = 0: default. Put routes into RT6_TABLE_MAIN as before. - > 0: manual. Put routes into the specified table. - < 0: automatic. Add the absolute value of the sysctl to the device's ifindex, and use that table. The automatic mode is most useful in conjunction with net.ipv6.conf.default.accept_ra_rt_table. A connection manager or distribution could set it to, say, -100 on boot, and thereafter just use IP rules.

Signed-off-by: Dima Zavin <dima@android.com> net: ipv4: Fix race in tcp_v4_nuke_addr(). To fix a recursive deadlock in 2.6.29, we stopped holding the hash table lock across tcp_done() calls. This fixed the deadlock, but introduced a race where the socket could die or change state. Fix: Before unlocking the hash table, we grab a reference to the socket. We can then unlock the hash table without risk of the socket going away. We then lock the socket, which is safe because it is pinned. We can then call tcp_done() without recursive deadlock and without race. Upon return, we unlock the socket and then unpin it, killing it.

| * vfio: Include No-IOMMU modeAlex Williamson2015-11-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is really no way to safely give a user full access to a DMA capable device without an IOMMU to protect the host system. There is also no way to provide DMA translation, for use cases such as device assignment to virtual machines. However, there are still those users that want userspace drivers even under those conditions. The UIO driver exists for this use case, but does not provide the degree of device access and programming that VFIO has. In an effort to avoid code duplication, this introduces a No-IOMMU mode for VFIO. This mode requires building VFIO with CONFIG_VFIO_NOIOMMU and enabling the "enable_unsafe_noiommu_mode" option on the vfio driver. This should make it very clear that this mode is not safe. Additionally, CAP_SYS_RAWIO privileges are necessary to work with groups and containers using this mode. Groups making use of this support are named /dev/vfio/noiommu-$GROUP and can only make use of the special VFIO_NOIOMMU_IOMMU for the container. Use of this mode, specifically binding a device without a native IOMMU group to a VFIO bus driver will taint the kernel and should therefore not be considered supported. This patch includes no-iommu support for the vfio-pci bus driver only. Signed-off-by: Alex Williamson <alex.williamson@redhat.com> Acked-by: Michael S. Tsirkin <mst@redhat.com>
