The current calculation in pfn_to_bitidx assumes that (pfn - zone->zone_start_pfn) >> pageblock_order will return the same bit for all pfn in a pageblock. If zone_start_pfn is not aligned to pageblock_nr_pages, this may not always be correct. Consider the following with pageblock order = 10, zone start 2MB: pfn | pfn - zone start | (pfn - zone start) >> page block order ---------------------------------------------------------------- 0x26000 | 0x25e00 | 0x97 0x26100 | 0x25f00 | 0x97 0x26200 | 0x26000 | 0x98 0x26300 | 0x26100 | 0x98 This means that calling {get,set}_pageblock_migratetype on a single page will not set the migratetype for the full block. Fix this by rounding down zone_start_pfn when doing the bitidx calculation. For our use case, the effects of this bug were mostly tied to the fact that CMA allocations would either take a long time or fail to happen. Depending on the driver using CMA, this could result in anything from visual glitches to application failures.

The tricky problem is this check: if (i++ >= max) icc (mis)optimizes this check as: if (++i > max) The check now becomes a no-op since max is MAX_ARG_STRINGS (0x7FFFFFFF). This is "allowed" by the C standard, assuming i++ never overflows, because signed integer overflow is undefined behavior. This optimization effectively reverts the previous commit 362e6663 ("exec.c, compat.c: fix count(), compat_count() bounds checking") that tries to fix the check. This patch simply moves ++ after the check.

when run the folloing command under shell, it will return error sh/$ echo 1 > /proc/sys/vm/compact_memory sh/$ sh: write error: Bad address After strace, I found the following log: ... write(1, "1\n", 2) = 3 write(1, "", 4294967295) = -1 EFAULT (Bad address) write(2, "echo: write error: Bad address\n", 31echo: write error: Bad address ) = 31 This tells system return 3(COMPACT_COMPLETE) after write data to compact_memory. The fix is to make the system just return 0 instead 3(COMPACT_COMPLETE) from sysctl_compaction_handler after compaction_nodes finished.

The memmove span covers from (next+1) to the end of the array, and the index of next is (i+1), so the index of (next+1) is (i+2). So the size of remaining array elements is (type->cnt - (i + 2)). Since the remaining elements of the memblock array are move forward by one element and there is only one additional element caused by this bug. So there won't be any write overflow here but read overflow. It may read one more element out of the array address if the array happens to be full. Commonly it doesn't matter at all but if the array happens to be located at the end a memblock, it may cause a invalid read operation for the physical address doesn't exist. There are 2 *happens to be* here, so I think the probability is quite low, I don't know if any guy is haunted by this bug before. Mostly I think it's user-invisible.

This was leading to a strange behaviour when using the fbcon driver on top of this one: the letters were in the right order, but each letter had a vertical symmetry.

由 Mel Gorman 提交于
Hugh Dickins pointed out that migrate_misplaced_transhuge_page() does not check page_count before migrating like base page migration and khugepage. He could not see why this was safe and he is right. The potential impact of the bug is avoided due to the limitations of NUMA balancing. The page_mapcount() check ensures that only a single address space is using this page and as THPs are typically private it should not be possible for another address space to fault it in parallel. If the address space has one associated task then it's difficult to have both a GUP pin and be referencing the page at the same time. If there are multiple tasks then a buggy scenario requires that another thread be accessing the page while the direct IO is in flight. This is dodgy behaviour as there is a possibility of corruption with or without THP migration. It would be While we happen to be safe for the most part it is shoddy to depend on such "safety" so this patch checks the page count similar to anonymous pages. Note that this does not mean that the page_mapcount() check can go away. If we were to remove the page_mapcount() check the the THP would have to be unmapped from all referencing PTEs, replaced with migration PTEs and restored properly afterwards.

In some cases, free_irq_cpu_rmap() is called while holding a lock (eg rtnl). This can lead to deadlocks, because it invokes flush_scheduled_work() which ends up waiting for whole system workqueue to flush, but some pending works might try to acquire the lock we are already holding. This commit uses reference-counting to replace irq_run_affinity_notifiers(). It also removes irq_run_affinity_notifiers() altogether.

The latest change to allow trace options to be set on the command line also broke the trace_options file. The zeroing of the last byte of the option name that is echoed into the trace_option file was removed with the consolidation of some of the code. The compare between the option and what was written to the trace_options file fails because the string holding the data written doesn't terminate with a null character. A zero needs to be added to the end of the string copied from user space. Signed-off-by: NSteven Rostedt <rostedt@goodmis.org>

Partially revert ae289dc1 "s390/3215: fix tty close handling", since this leads sometimes to hanging agetty processes and therefore systems that get stuck while starting. This was magically fixed (bisected) by a common code patch from Alan Cox: 36b3c070 "tty: Move the handling of the tty release logic", however it was unrelated. Since the removed code worked for a decade, nobody knows anymore why it was in there in the first place and debugging the observed hang is non-trivial (at least for me :) ), let's just re-add the removed code before we see other side effects.

Count CPU Restart events and make them visible via /proc/interrupts. Every CPU hotplug (online) event will increase the per cpu counter. Signed-off-by: NHeiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: NMartin Schwidefsky <schwidefsky@de.ibm.com>

Now that irq sum accounting for /proc/stat's "intr" line works again we have the oddity that the sum field (first field) contains only the sum of the second (external irqs) and third field (I/O interrupts). The reason for that is that these two fields are already sums of all other fields. So if we would sum up everything we would count every interrupt twice. This is broken since the split interrupt accounting was merged two years ago: 052ff461 "[S390] irq: have detailed statistics for interrupt types". To fix this remove the split interrupt fields from /proc/stat's "intr" line again and only have them in /proc/interrupts. This restores the old behaviour, seems to be the only sane fix and mimics a behaviour from other architectures where /proc/interrupts also contains more than /proc/stat's "intr" line does.

For more than two years, since f2c66cd8 "/proc/stat: scalability of irq num per cpu" the output of /proc/stat is broken. The first field in the "intr" line should contain the sum of all interrupts, however since the above mentioned change it is always zero. The reason for that is that a per cpu irq sum variable had been introduced which got incremented when calling kstat_incr_irqs_this_cpu(). However on s390 we directly incremented only the per cpu per irq counter by accessing the array element via kstat_cpu(smp_processor_id()).irqs[...]. So fix this and use the kstat_incr_irqs_this_cpu() wrapper which increments both: the per cpu per irq counter and the per cpu irq sum counter.
