2021-01-11scsi: target: Fix XCOPY NAA identifier lookupDavid Disseldorp
When attempting to match EXTENDED COPY CSCD descriptors with corresponding se_devices, target_xcopy_locate_se_dev_e4() currently iterates over LIO's global devices list which includes all configured backstores. This change ensures that only initiator-accessible backstores are considered during CSCD descriptor lookup, according to the session's se_node_acl LUN list. To avoid LUN removal race conditions, device pinning is changed from being configfs based to instead using the se_node_acl lun_ref.

2021-01-11tracing/kprobes: Do the notrace functions check without kprobes on ftraceMasami Hiramatsu
Enable the notrace function check on the architecture which doesn't support kprobes on ftrace but support dynamic ftrace. This notrace function check is not only for the kprobes on ftrace but also sw-breakpoint based kprobes. Thus there is no reason to limit this check for the arch which supports kprobes on ftrace. This also changes the dependency of Kconfig. Because kprobe event uses the function tracer's address list for identifying notrace function, if the CONFIG_DYNAMIC_FTRACE=n, it can not check whether the target function is notrace or not.

Commit a44f7cb93732 ("mmc: core: use mrq->sbc when sending CMD23 for RPMB") began to use ACMD23 for RPMB if the host supports ACMD23. In RPMB ACM23 case, we need to set bit 31 to CMD23 argument, otherwise RPMB write operation will return general fail. However, no matter V4 is enabled or not, the dwcmshc's ARGUMENT2 register is 32-bit block count register which doesn't support stuff bits of CMD23 argument. So let's handle this specific ACMD23 case. From another side, this patch also prepare for future v4 enabling for dwcmshc, because from the 4.10 spec, the ARGUMENT2 register is redefined as 32bit block count which doesn't support stuff bits of CMD23 argument.

2021-01-11drm/i915/backlight: fix CPU mode backlight takeover on LPTJani Nikula
The pch_get_backlight(), lpt_get_backlight(), and lpt_set_backlight() functions operate directly on the hardware registers. If inverting the value is needed, using intel_panel_compute_brightness(), it should only be done in the interface between hardware registers and panel->backlight.level. The CPU mode takeover code added in commit 5b1ec9ac7ab5 ("drm/i915/backlight: Fix backlight takeover on LPT, v3.") reads the hardware register and converts to panel->backlight.level correctly, however the value written back should remain in the hardware register "domain". This hasn't been an issue, because GM45 machines are the only known users of i915.invert_brightness and the brightness invert quirk, and without one of them no conversion is made. It's likely nobody's ever hit the problem. Fixes: 5b1ec9ac7ab5 ("drm/i915/backlight: Fix backlight takeover on LPT, v3.")

2021-01-11drm/i915/dsi: Use unconditional msleep for the panel_on_delay when there is ↵Hans de Goede
no reset-deassert MIPI-sequence Commit 25b4620ee822 ("drm/i915/dsi: Skip delays for v3 VBTs in vid-mode") added an intel_dsi_msleep() helper which skips sleeping if the MIPI-sequences have a version of 3 or newer and the panel is in vid-mode; and it moved a bunch of msleep-s over to this new helper. This was based on my reading of the big comment around line 730 which starts with "Panel enable/disable sequences from the VBT spec.", where the "v3 video mode seq" column does not have any wait t# entries. Given that this code has been used on a lot of different devices without issues until now, it seems that my interpretation of the spec here is mostly correct. But now I have encountered one device, an Acer Aspire Switch 10 E SW3-016, where the panel will not light up unless we do actually honor the panel_on_delay after exexuting the MIPI_SEQ_PANEL_ON sequence. What seems to set this model apart is that it is lacking a MIPI_SEQ_DEASSERT_RESET sequence, which is where the power-on delay usually happens. Fix the panel not lighting up on this model by using an unconditional msleep(panel_on_delay) instead of intel_dsi_msleep() when there is no MIPI_SEQ_DEASSERT_RESET sequence.

2021-01-10NFS/pNFS: Fix a leak of the layout 'plh_outstanding' counterTrond Myklebust

2021-01-10NFS/pNFS: Don't leak DS commits in pnfs_generic_retry_commit()Trond Myklebust
We must ensure that we pass a layout segment to nfs_retry_commit() when we're cleaning up after pnfs_bucket_alloc_ds_commits(). Otherwise, requests that should be committed to the DS will get committed to the MDS. Do so by ensuring that pnfs_bucket_get_committing() always tries to return a layout segment when it returns a non-empty page list.

2021-01-10NFS/pNFS: Don't call pnfs_free_bucket_lseg() before removing the requestTrond Myklebust

2021-01-10net: sunrpc: interpret the return value of kstrtou32 correctlyj.nixdorf@avm.de
A return value of 0 means success. This is documented in lib/kstrtox.c. This was found by trying to mount an NFS share from a link-local IPv6 address with the interface specified by its index: mount("[fe80::1%1]:/srv/nfs", "/mnt", "nfs", 0, "nolock,addr=fe80::1%1") Before this commit this failed with EINVAL and also caused the following message in dmesg: [...] NFS: bad IP address specified: addr=fe80::1%1 The syscall using the same address based on the interface name instead of its index succeeds. Credits for this patch go to my colleague Christian Speich, who traced the origin of this bug to this line of code.

2021-01-10NFS: Adjust fs_context error loggingScott Mayhew
Several existing dprink()/dfprintk() calls were converted to use the new mount API logging macros by commit ce8866f0913f ("NFS: Attach supplementary error information to fs_context"). If the fs_context was not created using fsopen() then it will not have had a log buffer allocated for it, and the new mount API logging macros will wind up calling printk(). This can result in syslog messages being logged where previously there were none... most notably "NFS4: Couldn't follow remote path", which can happen if the client is auto-negotiating a protocol version with an NFS server that doesn't support the higher v4.x versions. Convert the nfs_errorf(), nfs_invalf(), and nfs_warnf() macros to check for the existence of the fs_context's log buffer and call dprintk() if it doesn't exist. Add nfs_ferrorf(), nfs_finvalf(), and nfs_warnf(), which do the same thing but take an NFS debug flag as an argument and call dfprintk(). Finally, modify the "NFS4: Couldn't follow remote path" message to use nfs_ferrorf().
