2018-06-07rtc: ensure rtc_set_alarm fails when alarms are not supportedAlexandre Belloni
When using RTC_ALM_SET or RTC_WKALM_SET with rtc_wkalrm.enabled not set, rtc_timer_enqueue() is not called and rtc_set_alarm() may succeed but the subsequent RTC_AIE_ON ioctl will fail. RTC_ALM_READ would also fail in that case. Ensure rtc_set_alarm() fails when alarms are not supported to avoid letting programs think the alarms are working for a particular RTC when they are not.

2018-06-07arm64: topology: Avoid checking numa mask for scheduler MC selectionJeremy Linton
The numa mask subset check can often lead to system hang or crash during CPU hotplug and system suspend operation if NUMA is disabled. This is mostly observed on HMP systems where the CPU compute capacities are different and ends up in different scheduler domains. Since cpumask_of_node is returned instead core_sibling, the scheduler is confused with incorrect cpumasks(e.g. one CPU in two different sched domains at the same time) on CPU hotplug. Lets disable the NUMA siblings checks for the time being, as NUMA in socket machines have LLC's that will assure that the scheduler topology isn't "borken". The NUMA check exists to assure that if a LLC within a socket crosses NUMA nodes/chiplets the scheduler domains remain consistent. This code will likely have to be re-enabled in the near future once the NUMA mask story is sorted. At the moment its not necessary because the NUMA in socket machines LLC's are contained within the NUMA domains. Further, as a defensive mechanism during hot-plug, lets assure that the LLC siblings are also masked.

2018-06-07ubi: fastmap: Correctly handle interrupted erasures in EBARichard Weinberger
Fastmap cannot track the LEB unmap operation, therefore it can happen that after an interrupted erasure the mapping still looks good from Fastmap's point of view, while reading from the PEB will cause an ECC error and confuses the upper layer. Instead of teaching users of UBI how to deal with that, we read back the VID header and check for errors. If the PEB is empty or shows ECC errors we fixup the mapping and schedule the PEB for erasure.

Ben Hutchings pointed out that 29b7a6fa1ec0 ("ubi: fastmap: Don't flush fastmap work on detach") does not really fix the problem, it just reduces the risk to hit the race window where fastmap work races against free()'ing ubi->volumes[]. The correct approach is making sure that no more fastmap work is in progress before we free ubi data structures. So we cancel fastmap work right after the ubi background thread is stopped. By setting ubi->thread_enabled to zero we make sure that no further work tries to wake the thread.

2018-06-07Btrfs: fiemap: pass correct bytenr when fm_extent_count is zeroRobbie Ko
[BUG] fm_mapped_extents is not correct when fm_extent_count is 0 Like: # mount /dev/vdb5 /mnt/btrfs # dd if=/dev/zero bs=16K count=4 oflag=dsync of=/mnt/btrfs/file # xfs_io -c "fiemap -v" /mnt/btrfs/file /mnt/btrfs/file: EXT: FILE-OFFSET BLOCK-RANGE TOTAL FLAGS 0: [0..127]: 25088..25215 128 0x1 When user space wants to get the number of file extents, set fm_extent_count to 0 to run fiemap and then read fm_mapped_extents. In the above example, fiemap will return with fm_mapped_extents set to 4, but it should be 1 since there's only one entry in the output. [REASON] The problem seems to be that disko is only set if fieinfo->fi_extents_max is set. And this member is initialized, in the generic ioctl_fiemap function, to the value of used-passed fm_extent_count. So when the user passes 0 then fi_extent_max is also set to zero and this causes btrfs to not initialize disko at all. Eventually this leads emit_fiemap_extent being called with a bogus 'phys' argument preventing proper fiemap entries merging. [FIX] Move the disko initialization earlier in extent_fiemap making it independent of user-passed arguments, allowing emit_fiemap_extent to properly handle consecutive extent entries.

2018-06-07apparmor: fix ptrace read checkJohn Johansen
The ptrace read check is incorrect resulting in policy that is broader than it needs to be. Fix the check so that read access permission can be properly detected when other ptrace flags are set.

2018-06-07apparmor: fix memory leak when deduping profile loadJohn Johansen
AppArmor is leaking the newly loaded profile and its proxy when the profile is an exact match to the currently loaded version. In this case the dedup check results in the profile being skipped and put without dealing with the proxy ref thus not breaking a circular refcount and causing a leak. BugLink: http://bugs.launchpad.net/bugs/1750594 Fixes: 5d5182cae401 ("apparmor: move to per loaddata files, instead of replicating in profiles") Signed-off-by: John Johansen <john.johansen@canonical.com>
2018-06-07apparmor: fix mediation of prlimitJohn Johansen
For primit apparmor requires that if target confinement does not match the setting task's confinement, the setting task requires CAP_SYS_RESOURCE. Unfortunately this was broken when rlimit enforcement was reworked to support labels.

2018-06-07apparmor: fixup secid map conversion to using IDRJohn Johansen
The IDR conversion did not handle an error case for when allocating a mapping fails, and it did not ensure that mappings did not allocate or use a 0 value, which is used as an invalid secid. Which is used when a mapping fails. Fixes: 3ae7eb49a2be ("apparmor: Use an IDR to allocate apparmor secids") Signed-off-by: John Johansen <john.johansen@canonical.com>

2018-06-07apparmor: Fix memory leak of rule on error exit pathTyler Hicks
Currently on the error exit path the allocated rule is not free'd causing a memory leak. Fix this by calling aa_audit_rule_free().

2018-06-07apparmor: modify audit rule support to support profile stacksJohn Johansen
Allows for audit rules, where a rule could specify a profile stack A//&B, while extending the current semantic so if the label specified in the audit rule is a subset of the secid it is considered a match. Eg. if the secid resolves to the label stack A//&B//&C Then an audit rule specifying a label of A - would match B - would match C - would match D - would not A//&B - would match as a subset A//&C - would match as a subset B//&C - would match as a subset A//&B//&C - would match A//&D - would not match, because while A does match, D is also specified and does not Note: audit rules are currently assumed to be coming from the root namespace.

2018-06-07apparmor: Add support for audit rule filteringMatthew Garrett
This patch adds support to Apparmor for integrating with audit rule filtering. Right now it only handles SUBJ_ROLE, interpreting it as a single component of a label. This is sufficient to get Apparmor working with IMA's appraisal rules without any modifications on the IMA side.

2018-06-07apparmor: update git and wiki locations in AppArmor docsJordan Glover
The apparmor information in the apparmor.rst file is out of date. Update it to the correct git reference for the master apparmor tree. Update the wiki location to use apparmor.net which forwards to the current wiki location on gitlab.com. Update user space tools address to gitlab.com.
