When memory is hot-added, all the memory is in offline state. So clear all zones' present_pages because they will be updated in online_pages() and offline_pages(). Otherwise, /proc/zoneinfo will corrupt: When the memory of node2 is offline: # cat /proc/zoneinfo ......

In free_area_init_core(), zone->managed_pages is set to an approximate value for lowmem, and will be adjusted when the bootmem allocator frees pages into the buddy system. But free_area_init_core() is also called by hotadd_new_pgdat() when hot-adding memory. As a result, zone->managed_pages of the newly added node's pgdat is set to an approximate value in the very beginning. Even if the memory on that node has node been onlined, /sys/device/system/node/nodeXXX/meminfo has wrong value: hot-add node2 (memory not onlined) cat /sys/device/system/node/node2/meminfo Node 2 MemTotal: 33554432 kB Node 2 MemFree: 0 kB Node 2 MemUsed: 33554432 kB Node 2 Active: 0 kB This patch fixes this problem by reset node managed pages to 0 after hot-adding a new node. 1. Move reset_managed_pages_done from reset_node_managed_pages() to reset_all_zones_managed_pages() 2. Make reset_node_managed_pages() non-static 3. Call reset_node_managed_pages() in hotadd_new_pgdat() after pgdat is initialized Signed-off-by:

One thing I did in this patch is fixing freepage accounting. If we clear guard page and link it onto isolate buddy list, we should not increase freepage count. This patch adds conditional branch to skip counting in this case. Without this patch, this overcounting happens frequently if guard order is set and CMA is used. Another thing fixed in this patch is the target to reset order. In __free_one_page(), we check the buddy page whether it is a guard page or not. And, if so, we should clear guard attribute on the buddy page and reset order of it to 0. But, current code resets original page's order rather than buddy one's. Maybe, this doesn't have any problem, because whole merged page's order will be re-assigned soon. But, it is better to correct code. Signed-off-by:

fsnotify() needs to merge inode and mount marks lists when notifying groups about events so that ignore masks from inode marks are reflected in mount mark notifications and groups are notified in proper order (according to priorities). Currently the sorting of the lists done by fsnotify_add_inode_mark() / fsnotify_add_vfsmount_mark() and fsnotify() differed which resulted ignore masks not being used in some cases. Fix the problem by always using the same comparison function when sorting / merging the mark lists. Thanks to Heinrich Schuchardt for improvements of my patch.

Several people have reported occasionally seeing processes stuck in compact_zone(), even triggering soft lockups, in 3.18-rc2+. Testing a revert of commit e14c720e ("mm, compaction: remember position within pageblock in free pages scanner") fixed the issue, although the stuck processes do not appear to involve the free scanner. Finally, by code inspection, the bug was found in isolate_migratepages() which uses a slightly different condition to detect if the migration and free scanners have met, than compact_finished(). That has not been a problem until commit e14c720e allowed the free scanner position between individual invocations to be in the middle of a pageblock. In a relatively rare case, the migration scanner position can end up at the beginning of a pageblock, with the free scanner position in the middle of the same pageblock. If it's the migration scanner's turn, isolate_migratepages() exits immediately (without updating the position), while compact_finished() decides to continue compaction, resulting in a potentially infinite loop. The system can recover only if another process creates enough high-order pages to make the watermark checks in compact_finished() pass. This patch fixes the immediate problem by bumping the migration scanner's position to meet the free scanner in isolate_migratepages(), when both are within the same pageblock. This causes compact_finished() to terminate properly. A more robust check in compact_finished() is planned as a cleanup for better future maintainability.

Having test_pages_isolated failure message as a warning confuses users into thinking that it is more serious than it really is. In reality, if called via CMA, allocation will be retried so a single test_pages_isolated failure does not prevent allocation from succeeding. Demote the warning message to an info message and reformat it such that the text "failed" does not appear and instead a less worrying "PFNS busy" is used. This message is trivially reproducible on a 10GB x86 machine on 3.16.y kernels configured with CONFIG_DMA_CMA. Signed-off-by:

Unlike SLUB, sometimes, object isn't started at the beginning of the slab in SLAB. This causes the unalignment problem after slab merging is supported by commit 12220dea ("mm/slab: support slab merge"). Following is the report from Markos that fail to boot on Malta with EVA.

However, in x86, kmalloc-256 is luckily aligned in 256 bytes, so the problem didn't happen on it. To fix this problem, this patch introduces alignment mismatch check in find_mergeable(). This will fix the problem. Signed-off-by:

Current pageblock isolation logic could isolate each pageblock individually. This causes freepage accounting problem if freepage with pageblock order on isolate pageblock is merged with other freepage on normal pageblock. We can prevent merging by restricting max order of merging to pageblock order if freepage is on isolate pageblock. A side-effect of this change is that there could be non-merged buddy freepage even if finishing pageblock isolation, because undoing pageblock isolation is just to move freepage from isolate buddy list to normal buddy list rather than to consider merging. So, the patch also makes undoing pageblock isolation consider freepage merge. When un-isolation, freepage with more than pageblock order and it's buddy are checked. If they are on normal pageblock, instead of just moving, we isolate the freepage and free it in order to get merged. Signed-off-by:

All the caller of __free_one_page() has similar freepage counting logic, so we can move it to __free_one_page(). This reduce line of code and help future maintenance. This is also preparation step for "mm/page_alloc: restrict max order of merging on isolated pageblock" which fix the freepage counting problem on freepage with more than pageblock order.

In free_pcppages_bulk(), we use cached migratetype of freepage to determine type of buddy list where freepage will be added. This information is stored when freepage is added to pcp list, so if isolation of pageblock of this freepage begins after storing, this cached information could be stale. In other words, it has original migratetype rather than MIGRATE_ISOLATE. There are two problems caused by this stale information. One is that we can't keep these freepages from being allocated. Although this pageblock is isolated, freepage will be added to normal buddy list so that it could be allocated without any restriction. And the other problem is incorrect freepage accounting. Freepages on isolate pageblock should not be counted for number of freepage. Following is the code snippet in free_pcppages_bulk(). /* MIGRATE_MOVABLE list may include MIGRATE_RESERVEs */ __free_one_page(page, page_to_pfn(page), zone, 0, mt); trace_mm_page_pcpu_drain(page, 0, mt); if (likely(!is_migrate_isolate_page(page))) { __mod_zone_page_state(zone, NR_FREE_PAGES, 1); if (is_migrate_cma(mt)) __mod_zone_page_state(zone, NR_FREE_CMA_PAGES, 1); } As you can see above snippet, current code already handle second problem, incorrect freepage accounting, by re-fetching pageblock migratetype through is_migrate_isolate_page(page). But, because this re-fetched information isn't used for __free_one_page(), first problem would not be solved. This patch try to solve this situation to re-fetch pageblock migratetype before __free_one_page() and to use it for __free_one_page(). In addition to move up position of this re-fetch, this patch use optimization technique, re-fetching migratetype only if there is isolate pageblock. Pageblock isolation is rare event, so we can avoid re-fetching in common case with this optimization. This patch also correct migratetype of the tracepoint output.

Before describing bugs itself, I first explain definition of freepage. 1. pages on buddy list are counted as freepage. 2. pages on isolate migratetype buddy list are *not* counted as freepage. 3. pages on cma buddy list are counted as CMA freepage, too. Now, I describe problems and related patch. Patch 1: There is race conditions on getting pageblock migratetype that it results in misplacement of freepages on buddy list, incorrect freepage count and un-availability of freepage. Patch 2: Freepages on pcp list could have stale cached information to determine migratetype of buddy list to go. This causes misplacement of freepages on buddy list and incorrect freepage count. Patch 4: Merging between freepages on different migratetype of pageblocks will cause freepages accouting problem. This patch fixes it. Without patchset [3], above problem doesn't happens on my CMA allocation test, because CMA reserved pages aren't used at all. So there is no chance for above race. With patchset [3], I did simple CMA allocation test and get below result: - Virtual machine, 4 cpus, 1024 MB memory, 256 MB CMA reservation - run kernel build (make -j16) on background - 30 times CMA allocation(8MB * 30 = 240MB) attempts in 5 sec interval - Result: more than 5000 freepage count are missed With patchset [3] and this patchset, I found that no freepage count are missed so that I conclude that problems are solved. On my simple memory offlining test, these problems also occur on that environment, too. This patch (of 4): There are two paths to reach core free function of buddy allocator, __free_one_page(), one is free_one_page()->__free_one_page() and the other is free_hot_cold_page()->free_pcppages_bulk()->__free_one_page(). Each paths has race condition causing serious problems. At first, this patch is focused on first type of freepath. And then, following patch will solve the problem in second type of freepath. In the first type of freepath, we got migratetype of freeing page without holding the zone lock, so it could be racy. There are two cases of this race. 1. pages are added to isolate buddy list after restoring orignal migratetype CPU1 CPU2 get migratetype => return MIGRATE_ISOLATE call free_one_page() with MIGRATE_ISOLATE grab the zone lock unisolate pageblock release the zone lock grab the zone lock call __free_one_page() with MIGRATE_ISOLATE freepage go into isolate buddy list, although pageblock is already unisolated This may cause two problems. One is that we can't use this page anymore until next isolation attempt of this pageblock, because freepage is on isolate buddy list. The other is that freepage accouting could be wrong due to merging between different buddy list. Freepages on isolate buddy list aren't counted as freepage, but ones on normal buddy list are counted as freepage. If merge happens, buddy freepage on normal buddy list is inevitably moved to isolate buddy list without any consideration of freepage accouting so it could be incorrect. 2. pages are added to normal buddy list while pageblock is isolated. It is similar with above case. This also may cause two problems. One is that we can't keep these freepages from being allocated. Although this pageblock is isolated, freepage would be added to normal buddy list so that it could be allocated without any restriction. And the other problem is same as case 1, that it, incorrect freepage accouting. This race condition would be prevented by checking migratetype again with holding the zone lock. Because it is somewhat heavy operation and it isn't needed in common case, we want to avoid rechecking as much as possible. So this patch introduce new variable, nr_isolate_pageblock in struct zone to check if there is isolated pageblock. With this, we can avoid to re-check migratetype in common case and do it only if there is isolated pageblock or migratetype is MIGRATE_ISOLATE. This solve above mentioned problems. Changes from v3: Add one more check in free_one_page() that checks whether migratetype is MIGRATE_ISOLATE or not. Without this, abovementioned case 1 could happens. Signed-off-by: -

Commit 7d49d886 ("mm, compaction: reduce zone checking frequency in the migration scanner") has a side-effect that changes the iteration range calculation. Before the change, block_end_pfn is calculated using start_pfn, but now it blindly adds pageblock_nr_pages to the previous value. This causes the problem that isolation_start_pfn is larger than block_end_pfn when we isolate the page with more than pageblock order. In this case, isolation would fail due to an invalid range parameter. To prevent this, this patch implements skipping the range until a proper target pageblock is met. Without this patch, CMA with more than pageblock order always fails but with this patch it will succeed. Signed-off-by:

zram could kunmap_atomic() a NULL pointer in a rare situation: a zram page becomes a full-zeroed page after a partial write io. The current code doesn't handle this case and performs kunmap_atomic() on a NULL pointer, which panics the kernel. This patch fixes this issue. Signed-off-by:

kick_requests() can put linger requests on the notarget list. This means we need to clear the much-overloaded req->r_req_lru_item in __unregister_linger_request() as well, or we get an assertion failure in ceph_osdc_release_request() - !list_empty(&req->r_req_lru_item). AFAICT the assumption was that registered linger requests cannot be on any of req->r_req_lru_item lists, but that's clearly not the case. Signed-off-by:

Pull audit fixes from Paul Moore: "After he sent the initial audit pull request for 3.18, Eric asked me to take over the management of the audit tree, hence this pull request to fix a couple of problems with audit. As you can see below, the changes are minimal: adding some whitespace to a string so userspace parses it correctly, and fixing a problem with audit's usage of fsnotify that was causing audit watch rules to be lost. Neither of these patches were very controversial on the mailing lists and they fix real problems, getting them into 3.18 would be a good thing" * 'stable-3.18' of git://git.infradead.org/users/pcmoore/audit: audit: keep inode pinned audit: AUDIT_FEATURE_CHANGE message format missing delimiting space

Lenovo Ideapad Z560 has a mute LED that is controlled via EAPD pin 0x1b on CX20585 codec. (EAPD bit on corresponds to mute LED on.) The machine doesn't need other EAPD, so the fixup concentrates on controlling EAPD 0x1b following the vmaster state (but inversely).

Merge tag 'trace-fixes-v3.18-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing fix from Steven Rostedt: "Rabin Vincent found a way that tracing could cause an infinite loop in the kernel. The splice logic wants a full page from the ring buffer but the ring_buffer_wait() returns when there's any data in the ring buffer. The splice code would then continue the loop waiting for a full page. But if a full page never happens, the splice code will never sleep and just continue to loop. There's another case that Rabin fixed that could loop if there's no memory and kmalloc() constantly returns NULL" * tag 'trace-fixes-v3.18-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Do not risk busy looping in buffer splice tracing: Do not busy wait in buffer splice

Convert WARN_ONCE() to printk() in selinux_nlmsg_perm(). After conversion from audit_log() in commit e173fb26, WARN_ONCE() was deemed too alarmist, so switch it to printk(). Signed-off-by:

This will fix no sound in Linux system after reboot from windows. Change log: - alc662_fill_coef() is replaced with alc_fill_eapd_coef_idx() and move into alc_auto_init_amp(). - For ALC262, ALC267, ALC268, ALC269, ALC233, ALC255, ALC280, ALC282, ALC283, ALC284, ALC285, ALC286, ALC288, ALC290, ALC292, ALC293, ALC294, ALC668, ALC888VC, ALC888VD, ALC891, ALC892, ALC898 and ALC1150, add update COEF control for EAPD setting. - Remove alc269_fill_coef() for update EAPD control line. ADDITIONAL NOTE: Many Realtek cdoecs have a COEF bit to switch the master amp control between COEF and EAPD. Windows drivers seem using COEF while we use EAPD, which is more standard. As a result, some system suffer from the silent output when booting after Windows. This patch sets the COEF bits on the relevant codecs properly to switch to EAPD control.
