2018-12-11fuse: continue to send FUSE_RELEASEDIR when FUSE_OPEN returns ENOSYSChad Austin3-12/+13
When FUSE_OPEN returns ENOSYS, the no_open bit is set on the connection. Because the FUSE_RELEASE and FUSE_RELEASEDIR paths share code, this incorrectly caused the FUSE_RELEASEDIR request to be dropped and never sent to userspace. Pass an isdir bool to distinguish between FUSE_RELEASE and FUSE_RELEASEDIR inside of fuse_file_put.

2018-12-11dm thin: send event about thin-pool state change _after_ making itMike Snitzer1-33/+35
Sending a DM event before a thin-pool state change is about to happen is a bug. It wasn't realized until it became clear that userspace response to the event raced with the actual state change that the event was meant to notify about. Fix this by first updating internal thin-pool state to reflect what the DM event is being issued about. This fixes a long-standing racey/buggy userspace device-mapper-test-suite 'resize_io' test that would get an event but not find the state it was looking for -- so it would just go on to hang because no other events caused the test to reevaluate the thin-pool's state.

2018-12-11tracing: Fix memory leak of instance function hash filtersSteven Rostedt (VMware)1-0/+1
The following commands will cause a memory leak: # cd /sys/kernel/tracing # mkdir instances/foo # echo schedule > instance/foo/set_ftrace_filter # rmdir instances/foo The reason is that the hashes that hold the filters to set_ftrace_filter and set_ftrace_notrace are not freed if they contain any data on the instance and the instance is removed.

2018-12-11tracing: Fix memory leak in set_trigger_filter()Steven Rostedt (VMware)1-2/+4
When create_event_filter() fails in set_trigger_filter(), the filter may still be allocated and needs to be freed. The caller expects the data->filter to be updated with the new filter, even if the new filter failed (we could add an error message by setting set_str parameter of create_event_filter(), but that's another update). But because the error would just exit, filter was left hanging and nothing could free it. Found by kmemleak detector.

2018-12-11tracing: Fix memory leak in create_filter()Steven Rostedt (VMware)1-1/+4
The create_filter() calls create_filter_start() which allocates a "parse_error" descriptor, but fails to call create_filter_finish() that frees it. The op_stack and inverts in predicate_parse() were also not freed. Found by kmemleak detector.

2018-12-11ceph: make 'nocopyfrom' a default mount optionLuis Henriques2-3/+5
Since we found a problem with the 'copy-from' operation after objects have been truncated, offloading object copies to OSDs should be discouraged until the issue is fixed. Thus, this patch adds the 'nocopyfrom' mount option to the default mount options which effectily means that remote copies won't be done in copy_file_range unless they are explicitly enabled at mount time.

2018-12-11Revert "drm/rockchip: Allow driver to be shutdown on reboot/kexec"Brian Norris1-6/+0
This reverts commit 7f3ef5dedb146e3d5063b6845781ad1bb59b92b5. It causes new warnings [1] on shutdown when running the Google Kevin or Scarlet (RK3399) boards under Chrome OS. Presumably our usage of DRM is different than what Marc and Heiko test. We're looking at a different approach (e.g., [2]) to replace this, but IMO the revert should be taken first, as it already propagated to -stable.

vr.vifi is indirectly controlled by user-space, hence leading to a potential exploitation of the Spectre variant 1 vulnerability.

2018-12-10backlight: pwm_bl: Fix brightness levels for non-DT case.Enric Balletbo i Serra1-6/+35
Commit '88ba95bedb79 ("backlight: pwm_bl: Compute brightness of LED linearly to human eye")' allows the possibility to compute a default brightness table when there isn't the brightness-levels property in the DT. Unfortunately the changes made broke the pwm backlight for the non-DT boards. Usually, the non-DT boards don't pass the brightness levels via platform data, instead, it sets the max_brightness in their platform data and the driver calculates the level without a table. The offending patch assumed that when there is no brightness levels table we should create one, but this is clearly wrong for the non-DT case. After this patch the code handles the DT and the non-DT case taking in consideration also if max_brightness is set or not.

The HP lt4132 is a rebranded Huawei ME906s-158 LTE modem. The interface with protocol 0x16 is "CDC ECM & NCM" according to the *.inf files included with the Windows driver. Attaching the option driver to it doesn't result in a /dev/ttyUSB* device being created, so I've excluded it. Note that it is also excluded for corresponding Huawei-branded devices, cf. commit d544db293a44 ("USB: support new huawei devices in option.c").
