[merged] mm-move_pages-return-valid-node-id-in-status-if-the-page-is-already-on-the-target-node.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: mm: move_pages: return valid node id in status if the page is already on the target node has been removed from the -mm tree. Its filename was mm-move_pages-return-valid-node-id-in-status-if-the-page-is-already-on-the-target-node.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Yang Shi <yang.shi(a)linux.alibaba.com> Subject: mm: move_pages: return valid node id in status if the page is already on the target node Felix Abecassis reports move_pages() would return random status if the pages are already on the target node by the below test program: ---8<--- int main(void) { const long node_id = 1; const long page_size = sysconf(_SC_PAGESIZE); const int64_t num_pages = 8; unsigned long nodemask = 1 << node_id; long ret = set_mempolicy(MPOL_BIND, &nodemask, sizeof(nodemask)); if (ret < 0) return (EXIT_FAILURE); void **pages = malloc(sizeof(void*) * num_pages); for (int i = 0; i < num_pages; ++i) { pages[i] = mmap(NULL, page_size, PROT_WRITE | PROT_READ, MAP_PRIVATE | MAP_POPULATE | MAP_ANONYMOUS, -1, 0); if (pages[i] == MAP_FAILED) return (EXIT_FAILURE); } ret = set_mempolicy(MPOL_DEFAULT, NULL, 0); if (ret < 0) return (EXIT_FAILURE); int *nodes = malloc(sizeof(int) * num_pages); int *status = malloc(sizeof(int) * num_pages); for (int i = 0; i < num_pages; ++i) { nodes[i] = node_id; status[i] = 0xd0; /* simulate garbage values */ } ret = move_pages(0, num_pages, pages, nodes, status, MPOL_MF_MOVE); printf("move_pages: %ld ", ret); for (int i = 0; i < num_pages; ++i) printf("status[%d] = %d ", i, status[i]); } ---8<--- Then running the program would return nonsense status values: $ ./move_pages_bug move_pages: 0 status[0] = 208 status[1] = 208 status[2] = 208 status[3] = 208 status[4] = 208 status[5] = 208 status[6] = 208 status[7] = 208 This is because the status is not set if the page is already on the target node, but move_pages() should return valid status as long as it succeeds. The valid status may be errno or node id. We can't simply initialize status array to zero since the pages may be not on node 0. Fix it by updating status with node id which the page is already on.

Account cred->security to kmemcg. Recently we saw high root slab usage on our production and on further inspection, we found a buggy application leaking processes. Though that buggy application was contained within its memcg but we observe much more system memory overhead, couple of GiBs, during that period. This overhead can adversely impact the isolation on the system. One of source of high overhead, we found was cred->secuity objects, which have a lifetime of at least the life of the process which allocated them.

[stable] x86/atomic functions missing memory clobber

by Ben Hutchings

I noticed that backports of commit 69d927bba395 "x86/atomic: Fix smp_mb__{before,after}_atomic()" didn't touch atomic_or_long() (present in 3.16) or atomic_inc_short() (present in 4.9 and earlier). These functions were only implemented on x86 and not actually used in- tree. But it's possible they are used by some out-of-tree module, and that commit removed compiler barriers for them. Would it might make sense to either 1. Add the memory clobber to these functions, or 2. Delete them on the affected stable branches?

[PATCH v4.9.z] pstore/ram: Write new dumps to start of recycled zones

by Kees Cook

From: Aleksandr Yashkin <a.yashkin(a)inango-systems.com> [ Upstream commit 9e5f1c19800b808a37fb9815a26d382132c26c3d ] The ram_core.c routines treat przs as circular buffers. When writing a new crash dump, the old buffer needs to be cleared so that the new dump doesn't end up in the wrong place (i.e. at the end). The solution to this problem is to reset the circular buffer state before writing a new Oops dump.
