Pull libnvdimm fix from Dan Williams: "This contains a regression fix for a problem that was introduced in v4.7-rc6. In 4.7-rc1 we introduced auto-probing for the ACPI DSM (device- specific-method) format that the platform firmware implements for nvdimm devices. We initially fixed a regression in probing the QEMU DSM implementation by making acpi_check_dsm() tolerant of the way QEMU reports the "0 DSMs supported" condition. However, that broke HPE platforms since that tolerance caused the driver to mistakenly match the 1-zero-byte response those platforms give to "unknown" commands. Instead, we simply make the driver tolerant of not finding any supported DSMs. This has been tested to work with both QEMU and HPE platforms. This commit has appeared in a -next release with no reported issues" * 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: nfit: make DIMM DSMs optional

Johannes Weiner authored
The memory controller has quite a bit of state that usually outlives the cgroup and pins its CSS until said state disappears. At the same time it imposes a 16-bit limit on the CSS ID space to economically store IDs in the wild. Consequently, when we use cgroups to contain frequent but small and short-lived jobs that leave behind some page cache, we quickly run into the 64k limitations of outstanding CSSs. Creating a new cgroup fails with -ENOSPC while there are only a few, or even no user-visible cgroups in existence. Although pinning CSSs past cgroup removal is common, there are only two instances that actually need an ID after a cgroup is deleted: cache shadow entries and swapout records. Cache shadow entries reference the ID weakly and can deal with the CSS having disappeared when it's looked up later. They pose no hurdle. Swap-out records do need to pin the css to hierarchically attribute swapins after the cgroup has been deleted; though the only pages that remain swapped out after offlining are tmpfs/shmem pages. And those references are under the user's control, so they are manageable. This patch introduces a private 16-bit memcg ID and switches swap and cache shadow entries over to using that. This ID can then be recycled after offlining when the CSS remains pinned only by objects that don't specifically need it. This script demonstrates the problem by faulting one cache page in a new cgroup and deleting it again: set -e mkdir -p pages for x in `seq 128000`; do [ $((x % 1000)) -eq 0 ] && echo $x mkdir /cgroup/foo echo $$ >/cgroup/foo/cgroup.procs echo trex >pages/$x echo $$ >/cgroup/cgroup.procs rmdir /cgroup/foo done When run on an unpatched kernel, we eventually run out of possible IDs even though there are no visible cgroups: [root@ham ~]# ./cssidstress.sh [...] 65000 mkdir: cannot create directory '/cgroup/foo': No space left on device After this patch, the IDs get released upon cgroup destruction and the cache and css objects get released once memory reclaim kicks in.

I stumbled over a build error with COMPILE_TEST and CONFIG_OF disabled: drivers/gpio/gpio-tegra.c: In function 'tegra_gpio_probe': drivers/gpio/gpio-tegra.c:603:9: error: 'struct gpio_chip' has no member named 'of_node' The problem is that the newly added GPIO_TEGRA Kconfig symbol does not have a dependency on CONFIG_OF. However, there is another problem here as the driver gets enabled unconditionally whenever COMPILE_TEST is set. This fixes both problems, by making the symbol user-visible when COMPILE_TEST is set and default-enabled for ARCH_TEGRA=y. As a side-effect, it is now possible to compile-test a Tegra kernel with GPIO support disabled, which is harmless.

Currently, osd_weight and osd_state fields are updated in the encoding order. This is wrong, because an incremental map may look like e.g. new_up_client: { osd=6, addr=... } # set osd_state and addr new_state: { osd=6, xorstate=EXISTS } # clear osd_state Suppose osd6's current osd_state is EXISTS (i.e. osd6 is down). After applying new_up_client, osd_state is changed to EXISTS | UP. Carrying on with the new_state update, we flip EXISTS and leave osd6 in a weird "!EXISTS but UP" state. A non-existent OSD is considered down by the mapping code 2087 for (i = 0; i < pg->pg_temp.len; i++) { 2088 if (ceph_osd_is_down(osdmap, pg->pg_temp.osds[i])) { 2089 if (ceph_can_shift_osds(pi)) 2090 continue; 2091 2092 temp->osds[temp->size++] = CRUSH_ITEM_NONE; and so requests get directed to the second OSD in the set instead of the first, resulting in OSD-side errors like: [WRN] : client.4239 192.168.122.21:0/2444980242 misdirected client.4239.1:2827 pg 2.5df899f2 to osd.4 not [1,4,6] in e680/680 and hung rbds on the client: [ 493.566367] rbd: rbd0: write 400000 at 11cc00000 (0) [ 493.566805] rbd: rbd0: result -6 xferred 400000 [ 493.567011] blk_update_request: I/O error, dev rbd0, sector 9330688 The fix is to decouple application from the decoding and: - apply new_weight first - apply new_state before new_up_client - twiddle osd_state flags if marking in - clear out some of the state if osd is destroyed Fixes: http://tracker.ceph.com/issues/14901 Cc: stable@vger.kernel.org # 3.15+: 6dd74e44: libceph: set 'exists' flag for newly up osd Cc: stable@vger.kernel.org # 3.15+ Signed-off-by: Ilya Dryomov <idryomov@gmail.com> Reviewed-by: Josh Durgin <jdurgin@redhat.com>

The upper dentry may become stale before we call ovl_lock_rename_workdir. For example, someone could (mistakenly or maliciously) manually unlink(2) it directly from upperdir. To ensure it is not stale, let's lookup it after ovl_lock_rename_workdir and and check if it matches the upper dentry. Essentially, it is the same problem and similar solution as in commit 11f37104 ("ovl: verify upper dentry before unlink and rename").

Passes input_id struct to the common probe function for the tsc200x drivers instead of just the bustype. This allows for the use of the product variable to set the input_dev->name variable according to the type of touchscreen used. Note that when we introduced support for TSC2004 we started calling everything TSC200X, so let's keep this quirk.

The size of individual keymap in drivers/tty/vt/keyboard.c is NR_KEYS, which is currently 256, whereas number of keys/buttons in input device (and therefor in key_down) is much larger - KEY_CNT - 768, and that can cause out-of-bound access when we do sym = U(key_maps[0][k]); with large 'k'. To fix it we should not attempt iterating beyond smaller of NR_KEYS and KEY_CNT. Also while at it let's switch to for_each_set_bit() instead of open-coding it.

This patch fixes an issue that a syscall (e.g. sendto syscall) cannot work correctly. Since the sendto syscall doesn't have msg_control buffer, the sock_tx_timestamp() in packet_snd() cannot work correctly because the socks.tsflags is set to 0. So, this patch sets the socks.tsflags to sk->sk_tsflags as default.

According to the RMI4 spec the maximum size of F12 control register 8 is 15 bytes. The current code incorrectly reports an error if control 8 is greater then 14.

The switchdev value for the SWITCHDEV_ATTR_ID_BRIDGE_AGEING_TIME attribute is a clock_t and requires to use helpers such as clock_t_to_jiffies() to convert to milliseconds. Change ageing_time type from u32 to clock_t to make it explicit.

Since Thadeu left IBM, EHEA has gone mostly unmaintained, since his email address doesn't work anymore. I'm stepping up to help maintain this driver upstream. I'm adding Thadeu's personal e-mail address in Cc, hoping that we can get his ack.

Tariq Toukan says: ==================== Safe flow for mlx4_en configuration change This patchset improves the mlx4_en driver resiliency, especially on systems with low memory. Upon a configuration change that requires the allocation of new resources, we first try to allocate, prior to destroying the current ones. Once it is successfully done, we release the old resources and attach the new ones. Otherwise, we stay with a functioning interface having the same old configuration. This improvement became of greater significance after removing the use of vmap. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

This patch fixes the lost of Ethernet port on low memory system, when driver frees its resources and fails to allocate new resources. Issue could happen while changing number of channels, rings size or changing the timestamp configuration. This fix is necessary because of removing vmap use in the code. When vmap was in use driver could allocate non-contiguous memory and make it contiguous with vmap. Now it could fail to allocate a large chunk of contiguous memory and lose the port. Current code tries to allocate new resources and then upon success frees the old resources.
