46097f2 Linus Torvalds 21 August 2016, 21:28:24 UTC Merge branch 'parisc-4.8-2' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux Pull two parisc fixes from Helge Deller: "The first patch ensures that the high-res cr16 clocksource (which was added in kernel 4.7) gets choosen as default clocksource for parisc. The second patch moves the #define of EREFUSED down inside errno.h and thus unbreaks building the gccgo compiler" * 'parisc-4.8-2' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: parisc: Fix order of EREFUSED define in errno.h parisc: Fix automatic selection of cr16 clocksource 21 August 2016, 21:28:24 UTC
4ec656b Tony Luck 20 August 2016, 23:27:58 UTC EDAC, skx_edac: Add EDAC driver for Skylake This is an entirely new driver instead of yet another set of patches to sb_edac.c because: 1) Mapping from PCI devices to socket/memory controller is significantly different. Skylake scatters devices on a socket across a number of PCI buses. 2) There is an extra level of interleaving via the "mcroute" register that would be a little messy to squeeze into the old driver. 3) Validation is getting too expensive. Changes to sb_edac need to be checked against Sandy Bridge, Ivy Bridge, Haswell, Broadwell and Knights Landing.

3eb53b2 Helge Deller 20 August 2016, 09:51:38 UTC parisc: Fix order of EREFUSED define in errno.h When building gccgo in userspace, errno.h gets parsed and the go include file sysinfo.go is generated. Since EREFUSED is defined to the same value as ECONNREFUSED, and ECONNREFUSED is defined later on in errno.h, this leads to go complaining that EREFUSED isn't defined yet. Fix this trivial problem by moving the define of EREFUSED down after ECONNREFUSED in errno.h (and clean up the indenting while touching this line).

ae14183 Helge Deller 19 August 2016, 20:39:02 UTC parisc: Fix automatic selection of cr16 clocksource Commit 54b66800907 (parisc: Add native high-resolution sched_clock() implementation) added support to use the CPU-internal cr16 counters as reliable clocksource with the help of HAVE_UNSTABLE_SCHED_CLOCK. Sadly the commit missed to remove the hack which prevented cr16 to become the default clocksource even on SMP systems.

6040e57 Linus Torvalds 19 August 2016, 19:47:01 UTC Make the hardened user-copy code depend on having a hardened allocator The kernel test robot reported a usercopy failure in the new hardened sanity checks, due to a page-crossing copy of the FPU state into the task structure. This happened because the kernel test robot was testing with SLOB, which doesn't actually do the required book-keeping for slab allocations, and as a result the hardening code didn't realize that the task struct allocation was one single allocation - and the sanity checks fail. Since SLOB doesn't even claim to support hardening (and you really shouldn't use it), the straightforward solution is to just make the usercopy hardening code depend on the allocator supporting it.

112dc0c Johannes Berg 11 August 2016, 09:50:22 UTC locking/barriers: Suppress sparse warnings in lockless_dereference() After Peter's commit: 331b6d8c7afc ("locking/barriers: Validate lockless_dereference() is used on a pointer type") ... we get a lot of sparse warnings (one for every rcu_dereference, and more) since the expression here is assigning to the wrong address space. Instead of validating that 'p' is a pointer this way, instead make it fail compilation when it's not by using sizeof(*(p)). This will not cause any sparse warnings (tested, likely since the address space is irrelevant for sizeof), and will fail compilation when 'p' isn't a pointer type. Tested-by: Paul E.

[...] Also, clue is in the name: 'dereference', you don't actually dereference the pointer here, only load it. My next patch breaks the compile without this revert, because it assumes you want to deference and thus also need the struct type visible (which it isn't here), so revert it. Tested-by: Paul E.

03cbc73 Wanpeng Li 17 August 2016, 02:05:46 UTC sched/cputime: Resync steal time when guest & host lose sync Commit: 57430218317e ("sched/cputime: Count actually elapsed irq & softirq time") ... fixed a bug but also triggered a regression: On an i5 laptop, 4 pCPUs, 4vCPUs for one full dynticks guest, there are four CPU hog processes(for loop) running in the guest, I hot-unplug the pCPUs on host one by one until there is only one left, then observe CPU utilization via 'top' in the guest, it shows: 100% st for cpu0(housekeeping) 75% st for other CPUs (nohz full mode) However, w/o this commit it shows the correct 75% for all four CPUs. When a guest is interrupted for a longer amount of time, missed clock ticks are not redelivered later. Because of that, we should not limit the amount of steal time accounted to the amount of time that the calling functions think have passed. However, the interval returned by account_other_time() is NOT rounded down to the nearest jiffy, while the base interval in get_vtime_delta() it is subtracted from is, so the max cputime limit is required to avoid underflow. This patch fixes the regression by limiting the account_other_time() from get_vtime_delta() to avoid underflow, and lets the other three call sites (in account_other_time() and steal_account_process_time()) account however much steal time the host told us elapsed.

12b40a2 Mathieu Poirier 18 July 2016, 16:43:06 UTC perf/core: Update filters only on executable mmap Function perf_event_mmap() is called by the MM subsystem each time part of a binary is loaded in memory. There can be several mapping for a binary, many times unrelated to the code section. Each time a section of a binary is mapped address filters are updated, event when the map doesn't pertain to the code section. The end result is that filters are configured based on the last map event that was received rather than the last mapping of the code segment. For example if we have an executable 'main' that calls library 'libcstest.so.1.0', and that we want to collect traces on code that is in that library. The perf cmd line for this scenario would be: perf record -e cs_etm// --filter 'filter 0x72c/0x40@/opt/lib/libcstest.so.1.0' --per-thread ./main Resulting in binaries being mapped this way: root@linaro-nano:~# cat /proc/1950/maps 00400000-00401000 r-xp 00000000 08:02 33169 /home/linaro/main 00410000-00411000 r--p 00000000 08:02 33169 /home/linaro/main 00411000-00412000 rw-p 00001000 08:02 33169 /home/linaro/main 7fa2464000-7fa2474000 rw-p 00000000 00:00 0 7fa2474000-7fa25a4000 r-xp 00000000 08:02 543 /lib/aarch64-linux-gnu/libc-2.21.so 7fa25a4000-7fa25b3000 ---p 00130000 08:02 543 /lib/aarch64-linux-gnu/libc-2.21.so 7fa25b3000-7fa25b7000 r--p 0012f000 08:02 543 /lib/aarch64-linux-gnu/libc-2.21.so 7fa25b7000-7fa25b9000 rw-p 00133000 08:02 543 /lib/aarch64-linux-gnu/libc-2.21.so 7fa25b9000-7fa25bd000 rw-p 00000000 00:00 0 7fa25bd000-7fa25be000 r-xp 00000000 08:02 38308 /opt/lib/libcstest.so.1.0 7fa25be000-7fa25cd000 ---p 00001000 08:02 38308 /opt/lib/libcstest.so.1.0 7fa25cd000-7fa25ce000 r--p 00000000 08:02 38308 /opt/lib/libcstest.so.1.0 7fa25ce000-7fa25cf000 rw-p 00001000 08:02 38308 /opt/lib/libcstest.so.1.0 7fa25cf000-7fa25eb000 r-xp 00000000 08:02 574 /lib/aarch64-linux-gnu/ld-2.21.so 7fa25ef000-7fa25f2000 rw-p 00000000 00:00 0 7fa25f7000-7fa25f9000 rw-p 00000000 00:00 0 7fa25f9000-7fa25fa000 r--p 00000000 00:00 0 [vvar] 7fa25fa000-7fa25fb000 r-xp 00000000 00:00 0 [vdso] 7fa25fb000-7fa25fc000 r--p 0001c000 08:02 574 /lib/aarch64-linux-gnu/ld-2.21.so 7fa25fc000-7fa25fe000 rw-p 0001d000 08:02 574 /lib/aarch64-linux-gnu/ld-2.21.so 7ff2ea8000-7ff2ec9000 rw-p 00000000 00:00 0 [stack] root@linaro-nano:~# Before 'main()' can execute 'libcstest.so.1.0' has to be loaded in memory. Once that has been done perf_event_mmap() has been called 4 times, with the last map starting at address 0x7fa25ce000 and the address filter configured to start filtering when the IP has passed over address 0x0x7fa25ce72c (0x7fa25ce000 + 0x72c). But that is wrong since the code segment for library 'libcstest.so.1.0' as been mapped at 0x7fa25bd000, resulting in traces not being collected.

The __max_logical_packages is computed as: DIV_ROUND_UP(total_cpus, ncpus); - ncpus being number of cores With above BIOS setup we get total_cpus == 16 which set __max_logical_packages to 2 (ncpus is 12). Once topology_update_package_map processes CPU with logical pkg over 2 we display above messages and fail to initialize the physical_to_logical_pkg map, which makes the uncore code crash. The fix is to remove logical_package_map bitmap completely and keep and update the logical_packages number instead. After we enumerate all the present CPUs, we check if the enumerated logical packages count is within its computed maximum from BIOS data. If it's not the case, we set this maximum to the new enumerated value and freeze any new addition of logical packages. The freeze is because lot of init code like uncore/rapl/cqm depends on having maximum logical package value set to allocate their data, so we can't change it later on. Prarit Bhargava tested the patch and confirms that it solves the problem: From dmidecode: Core Count: 24 Core Enabled: 24 Thread Count: 48 Orig kernel boot log: [ 0.464981] smpboot: Max logical packages: 19 [ 0.469861] smpboot: APIC(0) Converting physical 0 to logical package 0 [ 0.477261] smpboot: APIC(40) Converting physical 1 to logical package 1 [ 0.484760] smpboot: APIC(80) Converting physical 2 to logical package 2 [ 0.492258] smpboot: APIC(c0) Converting physical 3 to logical package 3 1. nr_cpus=8, should stop enumerating in package 0: [ 0.533664] smpboot: APIC(0) Converting physical 0 to logical package 0 [ 0.539596] smpboot: Max logical packages: 19 2. max_cpus=8, should still enumerate all packages: [ 0.526494] smpboot: APIC(0) Converting physical 0 to logical package 0 [ 0.532428] smpboot: APIC(40) Converting physical 1 to logical package 1 [ 0.538456] smpboot: APIC(80) Converting physical 2 to logical package 2 [ 0.544486] smpboot: APIC(c0) Converting physical 3 to logical package 3 [ 0.550524] smpboot: Max logical packages: 19 3. nr_cpus=49 ( 2 socket + 1 core on 3rd socket), should stop enumerating in package 2: [ 0.521378] smpboot: APIC(0) Converting physical 0 to logical package 0 [ 0.527314] smpboot: APIC(40) Converting physical 1 to logical package 1 [ 0.533345] smpboot: APIC(80) Converting physical 2 to logical package 2 [ 0.539368] smpboot: Max logical packages: 19 4. maxcpus=49, should still enumerate all packages: [ 0.525591] smpboot: APIC(0) Converting physical 0 to logical package 0 [ 0.531525] smpboot: APIC(40) Converting physical 1 to logical package 1 [ 0.537547] smpboot: APIC(80) Converting physical 2 to logical package 2 [ 0.543579] smpboot: APIC(c0) Converting physical 3 to logical package 3 [ 0.549624] smpboot: Max logical packages: 19 5. kdump (nr_cpus=1) works as well.

Instead, we could just save pointers to these actions in tcf_exts, since they are refcount'ed, so convert the list to an array of pointers. The "ugly" part is the action API still accepts list as a parameter, I just introduce a helper function to convert the array of pointers to a list, instead of relying on the C99 feature to iterate the array.

Kshitiz Gupta provides a fix for igb to resolve the PHY delay compensation math in several functions. Jarod Wilson provides a fix for e1000e which had to broken up into 2 patches, first is prepares the driver for expanding the list of NICs that have occasional ~10 hour clock jumps when being used for PTP. Second patch actually fixes i218 silicon which has been experiencing the clock jumps while using PTP. Alex provides 2 patches for ixgbe now that he is back at Intel. First fixes setting VLNCTRL.VFE bit, which was left unchanged in earlier patches which resulted in disabling VLAN filtering for all the VFs. Second corrects the support for disabling the VLAN tag filtering via the feature bit. Lastly, David fixes i40e which was causing a kernel panic when non-contiguous traffic classes or traffic classes not starting with TC0, were configured on a link partner switch. To fix this, changed the logic when determining the total number of TCs enabled. ==================== Signed-off-by: David S. Miller <davem@davemloft.net> 17 August 2016, 23:20:24 UTC

Since the FDB delayed work is still active when ports are removed it's possible for it to process FDB notifications of inactive ports, resulting in a warning message. Fix that by marking ports as inactive only after unregistering them.

There is no reason to reserve disk blocks in the transaction when allocating blocks for delalloc space as we already reserved the space when creating the delalloc extent. With this fix we stop running out of the reserved pool in generic/229, which has happened for long time with small blocksize file systems, and has increased in severity with the new buffered write path.

4dd3fd7 Brian Foster 16 August 2016, 22:30:28 UTC xfs: don't assert fail on non-async buffers on ioacct decrement The buffer I/O accounting mechanism tracks async buffers under I/O. As an optimization, the buffer I/O count is incremented only once on the first async I/O for a given hold cycle of a buffer and decremented once the buffer is released to the LRU (or freed). xfs_buf_ioacct_dec() has an ASSERT() check for an XBF_ASYNC buffer, but we have one or two corner cases where a buffer can be submitted for I/O multiple times via different methods in a single hold cycle. If an async I/O occurs first, the I/O count is incremented. If a sync I/O occurs before the hold count drops, XBF_ASYNC is cleared by the time the I/O count is decremented. Remove the async assert check from xfs_buf_ioacct_dec() as this is a perfectly valid scenario. For the purposes of I/O accounting, we really only care about the buffer async state at I/O submission time.

To fix this, the patch changes the logic when determining the total number of TCs enabled. Before, this would use the highest TC number enabled and assume that all TCs below it were also enabled. Now, we create a bitmask of enabled TCs and scan it to determine not only the number of TCs, but also if the set of enabled TCs starts at zero and is contiguous. If not, then DCB is disabled by only returning one TC.

There are two instances in which PHY delay compensations should be made: - Before the packet transmission over the PHY, the latency between when the packet is timestamped and transmission of the packets, should be an add operation, but it is currently a subtract. - After the packets are received from the PHY, the latency between the receiving and timestamping of the packets should be a subtract operation, but it is currently an add.

If it walks off the end of the list of nodes, it walks the list of memory zones to find the next region of memory. If it walks off the end of the list of zones, it returns false. This leaves the struct bm_position's node and zone pointers pointing at their respective struct list_heads in struct mem_zone_bm_rtree. memory_bm_find_bit() uses struct bm_position's node and zone pointers to avoid walking lists and trees if the next bit appears in the same node/zone. It handles these values being stale. Swap rtree_next_node()s 'step then test' to 'test-next then step', this means if we reach the end of memory we return false and leave the node and zone pointers as they were.

This behaviour was exposed by commit 6dbecfd345a6 ("PM / hibernate: Simplify mark_unsafe_pages()"), which caused mark_unsafe_pages() to call duplicate_memory_bitmap(), which uses memory_bm_find_bit() after walking off the end of the memory bitmap.

Also the "disconnect" IRQ will have ISR to invoke xhci_free_virt_device() in this sequence. xhci_irq -> xhci_handle_event -> handle_cmd_completion -> xhci_handle_cmd_disable_slot -> xhci_free_virt_device If xhci->devs[slot_id] has been assigned to NULL in xhci_free_virt_device(), then virt_dev->eps[i].ring in xhci_stop_device() may point to an invlid address to cause kernel panic. virt_dev = xhci->devs[slot_id]; : if (virt_dev->eps[i].ring && virt_dev->eps[i].ring->dequeue) [] Unable to handle kernel paging request at virtual address 00001a68 [] pgd=ffffffc001430000 [] [00001a68] *pgd=000000013c807003, *pud=000000013c807003, *pmd=000000013c808003, *pte=0000000000000000 [] Internal error: Oops: 96000006 [#1] PREEMPT SMP [] CPU: 0 PID: 39 Comm: kworker/0:1 Tainted: G U [] Workqueue: pm pm_runtime_work [] task: ffffffc0bc0e0bc0 ti: ffffffc0bc0ec000 task.ti: ffffffc0bc0ec000 [] PC is at xhci_stop_device.constprop.11+0xb4/0x1a4 This issue is found when running with realtek ethernet device (0bda:8153).
