2016-07-27net: asix: autoneg will set WRITE_MEDIUM regpatch_net_usb_asix_v2Grant Grundler1-4/+1
The miii_nway_restart() causes a PHY link change activity and ax88772_link_reset will be called. link_reset will set AX_CMD_WRITE_MEDIUM_MODE register correctly. The asix_write_medium_mode in reset() fills in a default value to the register which may be different from the negotiation result. So do this first. Ignore the ret value since it's ignored in link_reset code too. Signed-off-by: Grant Grundler <grundler@google.com> Signed-off-by: Robert Foss <robert.foss@collabora.com>
2016-07-27net: asix: see 802.3 spec for phy resetGrant Grundler1-3/+24
https://lkml.org/lkml/2014/11/11/947 Ben Hutchings is correct. IEEE 802.3 spec section "22.2.4.1.1 Reset" requires up to 500ms delay. Mitigate the "max" delay by polling the phy until BCM_RESET bit is clear. Signed-off-by: Grant Grundler <grundler@chromium.org> Signed-off-by: Robert Foss <robert.foss@collabora.com>

2016-07-27net: asix: Add in_pm parameterFreddy Xin4-150/+472
In order to R/W registers in suspend/resume functions, in_pm flags are added to some functions to determine whether the nopm version of usb functions is called. Save BMCR and ANAR PHY registers in suspend function and restore them in resume function. Reset HW in resume function to ensure the PHY works correctly.

git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2 Pull gfs2 updates from Bob Peterson: "We've got ten patches this time, half of which are related to a plethora of nasty outcomes when inodes are transitioned from the unlinked state to the free state. Small file systems are particularly vulnerable to these problems, and it can manifest as mainly hangs, but also file system corruption. The patches have been tested for literally many weeks, with a very gruelling test, so I have a high level of confidence. - Andreas Gruenbacher wrote a series of five patches for various lockups during the transition of inodes from unlinked to free. The main patch is titled "Fix gfs2_lookup_by_inum lock inversion" and the other four are support and cleanup patches related to that. - Ben Marzinski contributed two patches with regard to a recreatable problem when gfs2 tries to write a page to a file that is being truncated, resulting in a BUG() in gfs2_remove_from_journal. Note that Ben had to export vfs function __block_write_full_page to get this to work properly. It's been posted a long time and he talked to various VFS people about it, and nobody seemed to mind. - I contributed 3 patches: o The first one fixes a memory corruptor: a race in which one process can overwrite the gl_object pointer set by another process, causing kernel panic and other symptoms. o The second patch fixes another race that resulted in a false-positive BUG_ON. This occurred when resource group reservations were freed by one process while another process was trying to grab a new reservation in the same resource group. o The third patch fixes a problem with doing journal replay when the journals are not all the same size" * tag 'gfs2-4.7.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2: GFS2: Fix gfs2_replay_incr_blk for multiple journal sizes GFS2: Check rs_free with rd_rsspin protection gfs2: writeout truncated pages fs: export __block_write_full_page gfs2: Lock holder cleanup gfs2: Large-filesystem fix for 32-bit systems gfs2: Get rid of gfs2_ilookup gfs2: Fix gfs2_lookup_by_inum lock inversion gfs2: Initialize iopen glock holder for new inodes GFS2: don't set rgrp gl_object until it's inserted into rgrp tree

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

2016-07-23mm: memcontrol: fix cgroup creation failure after many small jobsJohannes Weiner3-24/+87
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.

2016-07-22gpio: tegra: don't auto-enable for COMPILE_TESTArnd Bergmann1-2/+5
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.

2016-07-22libceph: apply new_state before new_up_client on incrementalsIlya Dryomov1-43/+113
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+: 6dd74e44dc1d: 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 11f3710417d0 ("ovl: verify upper dentry before unlink and rename").

2016-07-21GFS2: Fix gfs2_replay_incr_blk for multiple journal sizesBob Peterson3-11/+10
Before this patch, if you used gfs2_jadd to add new journals of a size smaller than the existing journals, replaying those new journals would withdraw. That's because function gfs2_replay_incr_blk was using the number of journal blocks (jd_block) from the superblock's journal pointer. In other words, "My journal's max size" rather than "the journal we're replaying's size." This patch changes the function to use the size of the pertinent journal rather than always using the journal we happen to be using. Signed-off-by: Bob Peterson <rpeterso@redhat.com>

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.
