Pull namespace updates from Eric Biederman: "After a lot of discussion and work we have finally reachanged a basic understanding of what is necessary to make unprivileged mounts safe in the presence of EVM and IMA xattrs which the last commit in this series reflects. While technically it is a revert the comments it adds are important for people not getting confused in the future. Clearing up that confusion allows us to seriously work on unprivileged mounts of fuse in the next development cycle. The rest of the fixes in this set are in the intersection of user namespaces, ptrace, and exec. I started with the first fix which started a feedback cycle of finding additional issues during review and fixing them. Culiminating in a fix for a bug that has been present since at least Linux v1.0. Potentially these fixes were candidates for being merged during the rc cycle, and are certainly backport candidates but enough little things turned up during review and testing that I decided they should be handled as part of the normal development process just to be certain there were not any great surprises when it came time to backport some of these fixes" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: Revert "evm: Translate user/group ids relative to s_user_ns when computing HMAC" exec: Ensure mm->user_ns contains the execed files ptrace: Don't allow accessing an undumpable mm ptrace: Capture the ptracer's creds not PT_PTRACE_CAP mm: Add a user_ns owner to mm_struct and fix ptrace permission checks

Pull audit updates from Paul Moore: "After the small number of patches for v4.9, we've got a much bigger pile for v4.10. The bulk of these patches involve a rework of the audit backlog queue to enable us to move the netlink multicasting out of the task/thread that generates the audit record and into the kernel thread that emits the record (just like we do for the audit unicast to auditd). While we were playing with the backlog queue(s) we fixed a number of other little problems with the code, and from all the testing so far things look to be in much better shape now. Doing this also allowed us to re-enable disabling IRQs for some netns operations ("netns: avoid disabling irq for netns id"). The remaining patches fix some small problems that are well documented in the commit descriptions, as well as adding session ID filtering support" * 'stable-4.10' of git://git.infradead.org/users/pcmoore/audit: audit: use proper refcount locking on audit_sock netns: avoid disabling irq for netns id audit: don't ever sleep on a command record/message audit: handle a clean auditd shutdown with grace audit: wake up kauditd_thread after auditd registers audit: rework audit_log_start() audit: rework the audit queue handling audit: rename the queues and kauditd related functions audit: queue netlink multicast sends just like we do for unicast sends audit: fixup audit_init() audit: move kaudit thread start from auditd registration to kaudit init (#2) audit: add support for session ID user filter audit: fix formatting of AUDIT_CONFIG_CHANGE events audit: skip sessionid sentinel value when auto-incrementing audit: tame initialization warning len_abuf in audit_log_execve_info audit: less stack usage for /proc/*/loginuid

We truncated the possible read iterator to s_maxbytes in commit c2a9737f ("vfs,mm: fix a dead loop in truncate_inode_pages_range()"), but our end condition handling was wrong: it's not an error to try to read at the end of the file. Reading past the end should return EOF (0), not EINVAL. See for example https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1649342 http://lists.gnu.org/archive/html/bug-coreutils/2016-12/msg00008.html where a md5sum of a maximally sized file fails because the final read is exactly at s_maxbytes.

The backlog queue handling in audit_log_start() is a little odd with some questionable design decisions, this patch attempts to rectify this with the following changes: * Never make auditd wait, ignore any backlog limits as we need auditd awake so it can drain the backlog queue. * When we hit a backlog limit and start dropping records, don't wake all the tasks sleeping on the backlog, that's silly. Instead, let kauditd_thread() take care of waking everyone once it has had a chance to drain the backlog queue. * Don't keep a global backlog timeout countdown, make it per-task. A per-task timer means we won't have all the sleeping tasks waking at the same time and hammering on an already stressed backlog queue. Signed-off-by:

The audit record backlog queue has always been a bit of a mess, and the moving the multicast send into kauditd_thread() from audit_log_end() only makes things worse. This patch attempts to fix the backlog queue with a better design that should hold up better under load and have less of a performance impact at syscall invocation time. While it looks like there is a log going on in this patch, the main change is the move from a single backlog queue to three queues: * A queue for holding records generated from audit_log_end() that haven't been consumed by kauditd_thread() (audit_queue). * A queue for holding records that have been sent via multicast but had a temporary failure when sending via unicast and need a resend (audit_retry_queue). * A queue for holding records that haven't been sent via unicast because no one is listening (audit_hold_queue). Special care is taken in this patch to ensure that the proper record ordering is preserved, e.g. we send everything in the hold queue first, then the retry queue, and finally the main queue.

Sending audit netlink multicast messages is bad for all the same reasons that sending audit netlink unicast messages is bad, so this patch reworks things so that we don't do the multicast send in audit_log_end(), we do it from the dedicated kauditd_thread thread just as we do for unicast messages.

Richard made this change some time ago but Eric backed it out because the rest of the supporting code wasn't ready.

Commit 4fd06960 ("Use the new x86 setup code for i386") introduced a reference to the make variable LINUX_INCLUDE. That reference got moved around a bit and copied twice and now there are three references to it. There has never been a definition of that variable. (Presumably that is because it started out as a mistyped reference to LINUXINCLUDE.) So this reference has always been an empty string. Let's remove it before it spreads any further. Signed-off-by:

The build system stopped generating ikconfig.h in v2.6.8. Remove an entry for it in dontdiff. There's also a reference to it in a small comment. Remove that comment too, as it is of little help in any case. Signed-off-by:

According to `man blockdev': --getsize Print device size (32-bit!) in sectors. Deprecated in favor of the --getsz option. ... --getsz Get size in 512-byte sectors. Hence, occurrences of `--getsize' should be replaced with `--getsz', which this commit has achieved as follows: $ cd "$repo" $ git grep -l -e --getsz Documentation/device-mapper/delay.txt Documentation/device-mapper/dm-crypt.txt Documentation/device-mapper/linear.txt Documentation/device-mapper/log-writes.txt Documentation/device-mapper/striped.txt Documentation/device-mapper/switch.txt $ cd Documentation/device-mapper $ sed -i s/getsize/getsz/g * Signed-off-by:

This reverts commit 6d31e3ba . This causes bootup problems for me both on my laptop and my desktop. What they have in common is that they have NVMe disks with dm-crypt, but it's not the same controller, so it's not controller-specific. Jens does not see it on his machine (also NVMe), so it's presumably something that triggers just on bootup. Possibly related to dm-crypt and the fact that I mark my luks volume with "allow-discards" in /etc/crypttab. It's 100% repeatable for me, which made it fairly straightforward to bisect the problem to this commit. Small mercies. So we don't know what the reason is yet, but the revert is needed to get things going again. Acked-by:
