2018-02-06idr: Delete idr_remove_ext functionMatthew Wilcox7-19/+14

2018-02-06orangefs: reverse sense of is-inode-stale test in d_revalidateMartin Brandenburg1-10/+7
If a dentry is deleted, then a dentry is recreated with the same handle but a different type (i.e. it was a file and now it's a symlink), then its a different inode. The check was backwards, so d_revalidate would not have noticed. Due to the design of the OrangeFS server, this is rather unlikely. It's also possible for the dentry to be deleted and recreated with the same type. This would be undetectable. It's a bit of a ship of Theseus.

2018-02-06orangefs: simplify orangefs_inode_is_staleMartin Brandenburg1-24/+30
Check whether this is a new inode at location of call. Raises the question of what to do with an unknown inode type. Old code would've marked the inode bad and returned ESTALE. Signed-off-by: Martin Brandenburg <[email protected]> Signed-off-by: Mike Marshall <[email protected]>
2018-02-06Orangefs: don't propogate whacky error codesMike Marshall1-0/+1
When we get an error return code from userspace (the client-core) we check to make sure it is a valid code. This patch maps the whacky return code to -EINVAL instead of propagating garbage back up the call chain potentially resulting in a hard-to-find train-wreck. The client-core doesn't have any business returning whacky return codes, but if it does, we don't want the kernel to crash as a result. Signed-off-by: Mike Marshall <[email protected]>

2018-02-06blk-wbt: account flush requests correctlyJens Axboe1-1/+9
Mikulas reported a workload that saw bad performance, and figured out what it was due to various other types of requests being accounted as reads. Flush requests, for instance. Due to the high latency of those, we heavily throttle the writes to keep the latencies in balance. But they really should be accounted as writes. Fix this by checking the exact type of the request. If it's a read, account as a read, if it's a write or a flush, account as a write. Any other request we disregard. Previously everything would have been mistakenly accounted as reads.

2018-02-06drm/i915/cnp: Properly handle VBT ddc pin out of bounds.Rodrigo Vivi1-2/+3
If the table result is out of bounds on the array map there is something really wrong with VBT pin so we don't return that vbt_pin, but only return 0 instead. This basically reverts commit 'a8e6f3888b05 ("drm/i915/cnp: Ignore VBT request for know invalid DDC pin.")' Also this properly fixes commit 9c3b2689d01f ("drm/i915/cnl: Map VBT DDC Pin to BSpec DDC Pin.") v2: Do in a way that we don't break other platforms. (Jani) v3: Keep debug message (Jani) v4: Don't mess with 0 mapping was noticed by Jani and addressed with a simple solution suggested by Lucas that makes this even simpler.

2018-02-06drm/i915/cmdparser: Do not check past the cmd length.Michal Srb1-0/+6
The command MEDIA_VFE_STATE checks bits at offset +2 dwords. However, it is possible to have MEDIA_VFE_STATE command with length = 0 + LENGTH_BIAS = 2. In that case check_cmd will read bits from the following command, or even past the end of the buffer. If the offset ends up outside of the command length, reject the command.

2018-02-06drm/i915/cmdparser: Check reg_table_count before derefencing.Michal Srb1-2/+2
The find_reg function was assuming that there is always at least one table in reg_tables. It is not always true. In case of VCS or VECS, the reg_tables is NULL and reg_table_count is 0, implying that no register-accessing commands are allowed. However, the command tables include commands such as MI_STORE_REGISTER_MEM. When trying to check such command, the find_reg would dereference NULL pointer. Now it will just return NULL meaning that the register was not found and the command will be rejected.

2018-02-06drm/i915/bxt, glk: Increase PCODE timeouts during CDCLK freq changingImre Deak3-9/+25
Currently we see sporadic timeouts during CDCLK changing both on BXT and GLK as reported by the Bugzilla: ticket. It's easy to reproduce this by changing the frequency in a tight loop after blanking the display. The upper bound for the completion time is 800us based on my tests, so increase it from the current 500us to 2ms; with that I couldn't trigger the problem either on BXT or GLK. Note that timeouts happened during both the change notification and the voltage level setting PCODE request. (For the latter one BSpec doesn't require us to wait for completion before further HW programming.) This issue is similar to commit 2c7d0602c815 ("drm/i915/gen9: Fix PCODE polling during CDCLK change notification") but there the PCODE request does complete (as shown by the mbox busy flag), only the reply we get from PCODE indicates a failure. So there we keep resending the request until a success reply, here we just have to increase the timeout for the one PCODE request we send. v2: - s/snb_pcode_request/sandybridge_pcode_write_timeout/ (Ville) Cc: Chris Wilson <[email protected]> Cc: Ville Syrjälä <[email protected]> Cc: <[email protected]> # v4.4+ Acked-by: Chris Wilson <[email protected]> (v1) Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=103326 Reviewed-by: Ville Syrjälä <[email protected]> Signed-off-by: Imre Deak <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected] (cherry picked from commit e76019a81921e87a4d9e7b3d86102bc708a6c227) Signed-off-by: Rodrigo Vivi <[email protected]>
2018-02-06drm/i915/gvt: Use KVM r/w to access guest opregionTina Zhang2-29/+70
For KVMGT, the guest opregion, which is handled by VFIO, is actually a piece of guest memory which won't be accessed by devices. So, its mfn shouldn't be obtained through VFIO interface. This patch uses KVM r/w interface to access the data in guest opregion. Fix the guest opregion accessing issue when host "intel_iommu=on". v3: - Remove mapped flag for KVM/VFIO usage, as it's useless for KVM. v2: - Set the gpa correctly when invoking KVM r/w operations.

2018-02-06drm/i915/gvt: Fix aperture read/write emulation when enable x-no-mmap=onChangbin Du4-59/+35
When add 'x-no-mmap=on' for vfio-pci option, aperture access in guest is emulated. But the vgpu_aperture_rw() function take wrong offset when do memcpy, since vgpu->gm.aperture_va is not the base of entire aperture. This mistake cause GPU command in guest get lost and so the seqno is not updated in engine HWSP. This patch fix this, and it also move the emulation code to kvmgt. Because only vfio need to emulate it. Put aperture rw to MMIO emulation path breaks assumptions in xengt. v2: Remove PAGE_ALIGN for size (zhenyu) Fixes: f090a00df9ec ("drm/i915/gvt: Add emulation for BAR2 (aperture) with normal file RW approach") Signed-off-by: Changbin Du <[email protected]> Signed-off-by: Zhi Wang <[email protected]> Signed-off-by: Rodrigo Vivi <[email protected]>

2018-02-06ACPI / bus: Parse tables as term_list for Dell XPS 9570 and Precision M5530Kai Heng Feng1-7/+31
The i2c touchpad on Dell XPS 9570 and Precision M5530 doesn't work out of box. The touchpad relies on its _INI method to update its _HID value from XXXX0000 to SYNA2393. Also, the _STA relies on value of I2CN to report correct status. Set acpi_gbl_parse_table_as_term_list so the value of I2CN can be correctly set up, and _INI can get run. The ACPI table in this machine is designed to get parsed this way. Also, change the quirk table to a more generic name.

The commit moves the erspan 'version' in 'struct erspan_metadata' in front of 'struct erspan_md2' for later extensibility, but breaks the existing metadata extraction code due to extra 4-byte size 'version'. The second patch fixes the case where tunnel device receives an erspan packet with different tunnel metadata (ex: version, index, hwid, direction), existing code overwrites the tunnel device's erspan configuration.

2018-02-06pvcalls-back: do not return error on inet_accept EAGAINStefano Stabellini1-1/+1
When the client sends a regular blocking accept request, the backend is expected to return only when the accept is completed, simulating a blocking behavior, or return an error. Specifically, on EAGAIN from inet_accept, the backend shouldn't return "EAGAIN" to the client. Instead, it should simply continue the wait. Otherwise, the client will send another accept request, which will cause another EAGAIN to be sent back, which is a waste of resources and not conforming to the expected behavior. Change the behavior by turning the "goto error" into a return.

Support the AFS dynamic root which is a pseudo-volume that doesn't connect to any server resource, but rather is just a root directory that dynamically creates mountpoint directories where the name of such a directory is the name of the cell. Such a mount can be created thus: mount -t afs none /afs -o dyn Dynamic root superblocks aren't shared except by bind mounts and propagation. Cell root volumes can then be mounted by referring to them by name, e.g.: ls /afs/grand.central.org/ ls /afs/.grand.central.org/ The kernel will upcall to consult the DNS if the address wasn't supplied directly.
