* | | | net/ipv6/addrconf: IPv6 tethering enhancementTianyi Gou2016-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Added new procfs flag to toggle the automatic addition of prefix routes on a per device basis. The new flag is accept_ra_prefix_route. Defaults to 1 as to not break existing behavior. CRs-Fixed: 435320 Change-Id: If25493890c7531c27f5b2c4855afebbbbf5d072a Acked-by: Harout S.

* | | | netfilter: xtables: hardidletimer target implementationBhavya Sokke Mallikarjunappa2016-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements a hardidletimer Xtables target that can be used to identify when interfaces have been idle for a certain period of time. Timers are identified by labels and are created when a rule is set with a new label. The rules also take a timeout value (in seconds) as an option. If more than one rule uses the same timer label, the timer will be restarted whenever any of the rules get a hit. One entry for each timer is created in sysfs. This attribute contains the timer remaining for the timer to expire. The attributes are located under the xt_idletimer class: /sys/class/xt_hardidletimer/timers/<label> When the timer expires, the target module sends a sysfs notification to the userspace, which can then decide what to do (eg. disconnect to save power) Compared to xt_IDLETIMER, xt_HARDIDLETIMER can send notifications when CPU is in suspend too, to notify the timer expiry Change-Id: I1723d44e02df864d63da7550766ea7d763076de2 Signed-off-by: Bhavya Sokke Mallikarjunappa <bsokke@codeaurora.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>
* | prctl: reset PR_SET_TIMERSLACK_PID value to avoid conflictAmit Pundir2016-02-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PR_SET_TIMERSLACK_PID value keep colliding with that of newer prctls in mainline (e.g. first with PR_SET_THP_DISABLE, and again with PR_MPX_ENABLE_MANAGEMENT). So reset PR_SET_TIMERSLACK_PID to a large number so as to avoid conflict in the near term while it is out of mainline tree.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | thread. Second argument is similar to PR_SET_TIMERSLACK, if non-zero then the slack is set to that value otherwise sets it to the default for the thread. Takes PID of the thread as the third argument. This allows power/performance management software to set timer slack for other threads according to its policy for the thread (such as when the thread is designated foreground vs. background activity) Change-Id: I744d451ff4e60dae69f38f53948ff36c51c14a3f Signed-off-by: Ruchi Kandoi <kandoiruchi@google.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Removing obsolete xt_socket_put_sk() and using sock_gen_put() instead. xt_socket_put_sk() was reintroduced for xt_qtaguid in one of the patches, but it turned out sock_gen_put() supersedes xt_socket_put_sk().

* | 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.
