I'm announcing the release of the 3.16.60 kernel. All users of the 3.16 kernel series should upgrade. The updated 3.16.y git tree can be found at: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-3.16.y and can be browsed at the normal kernel.org git web browser: https://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git The diff from 3.16.59 is attached to this message.

[PATCH v4] selinux: policydb - fix byte order and alignment issues

by Ondrej Mosnacek

Do the LE conversions before doing the Infiniband-related range checks. The incorrect checks are otherwise causing a failure to load any policy with an ibendportcon rule on BE systems. This can be reproduced by running (on e.g. ppc64): cat >my_module.cil <<EOF (type test_ibendport_t) (roletype object_r test_ibendport_t) (ibendportcon mlx4_0 1 (system_u object_r test_ibendport_t ((s0) (s0)))) EOF semodule -i my_module.cil Also, fix loading/storing the 64-bit subnet prefix for OCON_IBPKEY to use a correctly aligned buffer. Finally, do not use the 'nodebuf' (u32) buffer where 'buf' (__le32) should be used instead. Tested internally on a ppc64 machine with a RHEL 7 kernel with this patch applied.

[PATCH] PCI / PM: Allow runtime PM without callback functions

by Jarkko Nikula

Allow PCI core to do runtime PM to devices without needing to use dummy runtime PM callback functions if there is no need to do anything device specific beyond PCI device power state management. Implement this by letting core to change device power state during runtime PM transitions even if no callback functions are defined. Fixes: a9c8088c7988 ("i2c: i801: Don't restore config registers on runtime PM") Reported-by: Mika Westerberg <mika.westerberg(a)linux.intel.com> Cc: <stable(a)vger.kernel.org> Signed-off-by: Jarkko Nikula <jarkko.nikula(a)linux.intel.com> --- This is related to my i2c-i801.c fix thread back in June which I completely forgot till now: https://lkml.org/lkml/2018/6/27/642 Discussion back then was that it should be handled in the PCI PM instead of having dummy functions in the drivers.

Use preempt_enable() instead, to not lose preemption events.

[PATCH 2/2] selftests/ftrace: Fix synthetic event test to delete event correctly

by Masami Hiramatsu

Fix the synthetic event test case to remove event correctly. If redirecting command to synthetic_event file without append mode, it cleans up all existing events and execute (parse) the command. This means "delete event" always fails to find the target event. Since previous synthetic event has a bug which doesn't return -ENOENT even if it fails to find the deleting event, this test passed. But fixing that bug, this test fails because this test itself has a bug. This fixes that bug by trying to delete event right after adding an event, and use append mode redirection ('>>') instead of normal redirection ('>').

4.14: Regression on ppc32 (early crash)

by Christoph Biedl

Hello, on both my ppc32 systems I've tested (G4 PowerMac and G4 Mac-mini), I see a regression after upgrading from 4.14.74 to 4.14.76: Very soon after starting the kernel from yaboot, they drop me into a OF prompt, message is "invalid memory access at" on the mini, and another one I forgot on the PowerMac. FWIW, the ppc64 G5 PowerMac does fine. Before I start bisecting - might take a few days -, is this already on radar? Christoph

How is dereferencing dentry->d_flags any better than dereferencing->d_inode when dentry has an invalid value? Thanks, Amir.

[PATCH 3/5] Drivers: hv: kvp: Fix the recent regression caused by incorrect clean-up

by kys＠linuxonhyperv.com

From: Dexuan Cui <decui(a)microsoft.com> In kvp_send_key(), we do need call process_ib_ipinfo() if message->kvp_hdr.operation is KVP_OP_GET_IP_INFO, because it turns out the userland hv_kvp_daemon needs the info of operation, adapter_id and addr_family. With the incorrect fc62c3b1977d, the host can't get the VM's IP via KVP. And, fc62c3b1977d added a "break;", but actually forgot to initialize the key_size/value in the case of KVP_OP_SET, so the default key_size of 0 is passed to the kvp daemon, and the pool files /var/lib/hyperv/.kvp_pool_* can't be updated. This patch effectively rolls back the previous fc62c3b1977d, and correctly fixes the "this statement may fall through" warnings. This patch is tested on WS 2012 R2 and 2016.

[PATCH v2] x86/microcode: Handle negative microcode revisions

by Andi Kleen

From: Andi Kleen <ak(a)linux.intel.com> The Intel microcode revision space is unsigned. Inside Intel there are special microcodes that have the highest bit set, and they are considered to have a higher revision than any microcodes that don't have this bit set. The function comparing the microcode revision in the Linux driver compares u32 with int, which ends up being signed extended to long on 64bit systems. This results in these highest bit set microcode revision not loading because their revision appears negative and smaller than the existing microcode. Change the comparison to unsigned. With that the loading works as expected.

[PATCH 1/3] tracing: Fix synthetic event to accept unsigned modifier

[PATCH 2/6] mm/rmap: map_pte() was not handling private ZONE_DEVICE page properly v3

by jglisse＠redhat.com

From: Ralph Campbell <rcampbell(a)nvidia.com> Private ZONE_DEVICE pages use a special pte entry and thus are not present. Properly handle this case in map_pte(), it is already handled in check_pte(), the map_pte() part was lost in some rebase most probably. Without this patch the slow migration path can not migrate back to any private ZONE_DEVICE memory to regular memory. This was found after stress testing migration back to system memory. This ultimatly can lead to the CPU constantly page fault looping on the special swap entry. Changes since v2: - add comments explaining what is going on Changes since v1: - properly lock pte directory in map_pte() Signed-off-by: Ralph Campbell <rcampbell(a)nvidia.com> Signed-off-by: Jérôme Glisse <jglisse(a)redhat.com> Reviewed-by: Balbir Singh <bsingharora(a)gmail.com> Cc: Andrew Morton <akpm(a)linux-foundation.org> Cc: Kirill A.

[PATCH v2] fsnotify: Fix busy inodes during unmount

by Jan Kara

Detaching of mark connector from fsnotify_put_mark() can race with unmounting of the filesystem like: CPU1 CPU2 fsnotify_put_mark() spin_lock(&conn->lock); ... inode = fsnotify_detach_connector_from_object(conn) spin_unlock(&conn->lock); generic_shutdown_super() fsnotify_unmount_inodes() sees connector detached for inode -> nothing to do evict_inode() barfs on pending inode reference iput(inode); Resulting in "Busy inodes after unmount" message and possible kernel oops. Make fsnotify_unmount_inodes() properly wait for outstanding inode references from detached connectors. Note that the accounting of outstanding inode references in the superblock can cause some cacheline contention on the counter. OTOH it happens only during deletion of the last notification mark from an inode (or during unlinking of watched inode) and that is not too bad. I have measured time to create & delete inotify watch 100000 times from 64 processes in parallel (each process having its own inotify group and its own file on a shared superblock) on a 64 CPU machine. Average and standard deviation of 15 runs look like: Avg Stddev Vanilla 9.817400 0.276165 Fixed 9.710467 0.228294 So there's no statistically significant difference.

[PATCH] ACPICA: Use 'jiffies' as the time bassis for acpi_os_get_timer()

by Bart Van Assche

Since acpi_os_get_timer() may be called after the timer subsystem has been suspended, use the jiffies counter instead of ktime_get(). This patch avoids that the following warning is reported during hibernation: WARNING: CPU: 0 PID: 612 at kernel/time/timekeeping.c:751 ktime_get+0x116/0x120 RIP: 0010:ktime_get+0x116/0x120 Call Trace: acpi_os_get_timer+0xe/0x30 acpi_ds_exec_begin_control_op+0x175/0x1de acpi_ds_exec_begin_op+0x2c7/0x39a acpi_ps_create_op+0x573/0x5e4 acpi_ps_parse_loop+0x349/0x1220 acpi_ps_parse_aml+0x25b/0x6da acpi_ps_execute_method+0x327/0x41b acpi_ns_evaluate+0x4e9/0x6f5 acpi_ut_evaluate_object+0xd9/0x2f2 acpi_rs_get_method_data+0x8f/0x114 acpi_walk_resources+0x122/0x1b6 acpi_pci_link_get_current.isra.2+0x157/0x280 acpi_pci_link_set+0x32f/0x4a0 irqrouter_resume+0x58/0x80 syscore_resume+0x84/0x380 hibernation_snapshot+0x20c/0x4f0 hibernate+0x22d/0x3a6 state_store+0x99/0xa0 kobj_attr_store+0x37/0x50 sysfs_kf_write+0x87/0xa0 kernfs_fop_write+0x1a5/0x240 __vfs_write+0xd2/0x410 vfs_write+0x101/0x250 ksys_write+0xab/0x120 __x64_sys_write+0x43/0x50 do_syscall_64+0x71/0x220 entry_SYSCALL_64_after_hwframe+0x49/0xbe Fixes: 164a08cee135 ("ACPICA: Dispatcher: Introduce timeout mechanism for infinite loop detection") Reported-by: Fengguang Wu <fengguang.wu(a)intel.com> References: https://lists.01.org/pipermail/lkp/2018-April/008406.html Cc: Rafael J.
