[PATCH] mm: move_pages: fix the return value if there are not-migrated pages

by Yang Shi

The do_move_pages_to_node() might return > 0 value, the number of pages that are not migrated, then the value will be returned to userspace directly. But, move_pages() syscall would just return 0 or errno. So, we need reset the return value to 0 for such case as what pre-v4.17 did.

[PATCH] jffs2: Fix integer underflow in jffs2_rtime_compress

by Richard Weinberger

The rtime compressor assumes that at least two bytes are compressed. If we try to compress just one byte, the loop condition will wrap around and an out-of-bounds write happens.

[Patch v4] mm: thp: remove the defer list related code since this will not happen

by Wei Yang

If compound is true, this means it is a PMD mapped THP. Which implies the page is not linked to any defer list. So the first code chunk will not be executed. Also with this reason, it would not be proper to add this page to a defer list. So the second code chunk is not correct. Based on this, we should remove the defer list related code.

[PATCH] mm: move_pages: report the number of non-attempted pages

by Yang Shi

Since commit a49bd4d71637 ("mm, numa: rework do_pages_move"), the semantic of move_pages() was changed to return the number of non-migrated pages (failed to migration) and the call would be aborted immediately if migrate_pages() returns positive value. But it didn't report the number of pages that we even haven't attempted to migrate. So, fix it by including non-attempted pages in the return value.

[for-linus][PATCH 2/5] tracing/uprobe: Fix double perf_event linking on multiprobe uprobe

by Steven Rostedt

From: Masami Hiramatsu <mhiramat(a)kernel.org> Fix double perf_event linking to trace_uprobe_filter on multiple uprobe event by moving trace_uprobe_filter under trace_probe_event. In uprobe perf event, trace_uprobe_filter data structure is managing target mm filters (in perf_event) related to each uprobe event. Since commit 60d53e2c3b75 ("tracing/probe: Split trace_event related data from trace_probe") left the trace_uprobe_filter data structure in trace_uprobe, if a trace_probe_event has multiple trace_uprobe (multi-probe event), a perf_event is added to different trace_uprobe_filter on each trace_uprobe. This leads a linked list corruption. To fix this issue, move trace_uprobe_filter to trace_probe_event and link it once on each event instead of each probe.

[PATCH v2] drm/dp_mst: Remove VCPI while disabling topology mgr

by Wayne Lin

[Why] This patch is trying to address the issue observed when hotplug DP daisy chain monitors. e.g. src-mstb-mstb-sst -> src (unplug) mstb-mstb-sst -> src-mstb-mstb-sst (plug in again) Once unplug a DP MST capable device, driver will call drm_dp_mst_topology_mgr_set_mst() to disable MST. In this function, it cleans data of topology manager while disabling mst_state. However, it doesn't clean up the proposed_vcpis of topology manager. If proposed_vcpi is not reset, once plug in MST daisy chain monitors later, code will fail at checking port validation while trying to allocate payloads. When MST capable device is plugged in again and try to allocate payloads by calling drm_dp_update_payload_part1(), this function will iterate over all proposed virtual channels to see if any proposed VCPI's num_slots is greater than 0. If any proposed VCPI's num_slots is greater than 0 and the port which the specific virtual channel directed to is not in the topology, code then fails at the port validation. Since there are stale VCPI allocations from the previous topology enablement in proposed_vcpi[], code will fail at port validation and reurn EINVAL. [How] Clean up the data of stale proposed_vcpi[] and reset mgr->proposed_vcpis to NULL while disabling mst in drm_dp_mst_topology_mgr_set_mst().
