2020-09-03drm/amdgpu: Specify get_argument function for ci_smu_funcsSandeep Raghuraman
Starting in Linux 5.8, the graphics and memory clock frequency were not being reported for CIK cards. This is a regression, since they were reported correctly in Linux 5.7. After investigation, I discovered that the smum_send_msg_to_smc() function, attempts to call the corresponding get_argument() function of ci_smu_funcs. However, the get_argument() function is not defined in ci_smu_funcs. This patch fixes the bug by specifying the correct get_argument() function.

Normally softwareshutdowntemp should be greater than Thotspotlimit. However, on some VEGA10 ASIC, the softwareshutdowntemp is 91C while Thotspotlimit is 105C.

2020-09-02block: allow for_each_bvec to support zero len bvecMing Lei
Block layer usually doesn't support or allow zero-length bvec. Since commit 1bdc76aea115 ("iov_iter: use bvec iterator to implement iterate_bvec()"), iterate_bvec() switches to bvec iterator. However, Al mentioned that 'Zero-length segments are not disallowed' in iov_iter. Fixes for_each_bvec() so that it can move on after seeing one zero length bvec.

2020-09-02tipc: fix shutdown() of connectionless socketTetsuo Handa
syzbot is reporting hung task at nbd_ioctl() [1], for there are two problems regarding TIPC's connectionless socket's shutdown() operation. ---------- #include <fcntl.h> #include <sys/socket.h> #include <sys/ioctl.h> #include <linux/nbd.h> #include <unistd.h> int main(int argc, char *argv[]) { const int fd = open("/dev/nbd0", 3); alarm(5); ioctl(fd, NBD_SET_SOCK, socket(PF_TIPC, SOCK_DGRAM, 0)); ioctl(fd, NBD_DO_IT, 0); /* To be interrupted by SIGALRM. */ return 0; } ---------- One problem is that wait_for_completion() from flush_workqueue() from nbd_start_device_ioctl() from nbd_ioctl() cannot be completed when nbd_start_device_ioctl() received a signal at wait_event_interruptible(), for tipc_shutdown() from kernel_sock_shutdown(SHUT_RDWR) from nbd_mark_nsock_dead() from sock_shutdown() from nbd_start_device_ioctl() is failing to wake up a WQ thread sleeping at wait_woken() from tipc_wait_for_rcvmsg() from sock_recvmsg() from sock_xmit() from nbd_read_stat() from recv_work() scheduled by nbd_start_device() from nbd_start_device_ioctl(). Fix this problem by always invoking sk->sk_state_change() (like inet_shutdown() does) when tipc_shutdown() is called. The other problem is that tipc_wait_for_rcvmsg() cannot return when tipc_shutdown() is called, for tipc_shutdown() sets sk->sk_shutdown to SEND_SHUTDOWN (despite "how" is SHUT_RDWR) while tipc_wait_for_rcvmsg() needs sk->sk_shutdown set to RCV_SHUTDOWN or SHUTDOWN_MASK. Fix this problem by setting sk->sk_shutdown to SHUTDOWN_MASK (like inet_shutdown() does) when the socket is connectionless.

2020-09-02drivers/net/wan/hdlc: Change the default of hard_header_len to 0Xie He
Change the default value of hard_header_len in hdlc.c from 16 to 0. Currently there are 6 HDLC protocol drivers, among them: hdlc_raw_eth, hdlc_cisco, hdlc_ppp, hdlc_x25 set hard_header_len when attaching the protocol, overriding the default. So this patch does not affect them. hdlc_raw and hdlc_fr don't set hard_header_len when attaching the protocol. So this patch will change the hard_header_len of the HDLC device for them from 16 to 0. This is the correct change because both hdlc_raw and hdlc_fr don't have header_ops, and the code in net/packet/af_packet.c expects the value of hard_header_len to be consistent with header_ops. In net/packet/af_packet.c, in the packet_snd function, for AF_PACKET/DGRAM sockets it would reserve a headroom of hard_header_len and call dev_hard_header to fill in that headroom, and for AF_PACKET/RAW sockets, it does not reserve the headroom and does not call dev_hard_header, but checks if the user has provided a header of length hard_header_len (in function dev_validate_header).

We recently added some calls to clk_disable_unprepare() but we missed the last error path if register_netdev() fails. I made a couple cleanups so we avoid mistakes like this in the future. First I reversed the "if (!ret)" condition and pulled the code in one indent level. Also, the "port->netdev = NULL;" is not required because "port" isn't used again outside this function so I deleted that line.

On SKL+ Intel platforms, the driver selection is handled by the snd_intel_dspcfg, and when the HDaudio legacy driver is not selected, be it with the auto-selection or user preferences with a kernel parameter, the probe aborts with no logs, only a -ENODEV return value. Having no dmesg trace, even with dynamic debug enabled, makes support more complicated than it needs to be, and even experienced users can be fooled. A simple dev_dbg() trace solves this problem.

2020-09-02ALSA: hda: fix a runtime pm issue in SOF when integrated GPU is disabledRander Wang
In snd_hdac_device_init pm_runtime_set_active is called to increase child_count in parent device. But when it is failed to build connection with GPU for one case that integrated graphic gpu is disabled, snd_hdac_ext_bus_device_exit will be invoked to clean up a HD-audio extended codec base device. At this time the child_count of parent is not decreased, which makes parent device can't get suspended. This patch calls pm_runtime_set_suspended to decrease child_count in parent device in snd_hdac_device_exit to match with snd_hdac_device_init. pm_runtime_set_suspended can make sure that it will not decrease child_count if the device is already suspended.

2020-09-02drm/i915: Clear the repeater bit on HDCP disableSean Paul
On HDCP disable, clear the repeater bit. This ensures if we connect a non-repeater sink after a repeater, the bit is in the state we expect.

2020-09-02drm/i915: Fix sha_text population codeSean Paul
This patch fixes a few bugs: 1- We weren't taking into account sha_leftovers when adding multiple ksvs to sha_text. As such, we were or'ing the end of ksv[j - 1] with the beginning of ksv[j] 2- In the sha_leftovers == 2 and sha_leftovers == 3 case, bstatus was being placed on the wrong half of sha_text, overlapping the leftover ksv value 3- In the sha_leftovers == 2 case, we need to manually terminate the byte stream with 0x80 since the hardware doesn't have enough room to add it after writing M0 The upside is that all of the HDCP supported HDMI repeaters I could find on Amazon just strip HDCP anyways, so it turns out to be _really_ hard to hit any of these cases without an MST hub, which is not (yet) supported. Oh, and the sha_leftovers == 1 case works perfectly!

2020-09-02drm/i915/display: Ensure that ret is always initialized in ↵Nathan Chancellor
icl_combo_phy_verify_state Clang warns: drivers/gpu/drm/i915/display/intel_combo_phy.c:268:3: warning: variable 'ret' is uninitialized when used here [-Wuninitialized] ret &= check_phy_reg(dev_priv, phy, ICL_PORT_TX_DW8_LN0(phy), ^~~ drivers/gpu/drm/i915/display/intel_combo_phy.c:261:10: note: initialize the variable 'ret' to silence this warning bool ret; ^ = 0 1 warning generated. In practice, the bug this warning appears to be concerned with would not actually matter because ret gets initialized to the return value of cnl_verify_procmon_ref_values. However, that does appear to be a bug since it means the first hunk of the patch this fixes won't actually do anything (since the values of check_phy_reg won't factor into the final ret value). Initialize ret to true then make all of the assignments a bitwise AND with itself so that the function always does what it should do.

ioc_pd_free() grabs irq-safe ioc->lock without ensuring that irq is disabled when it can be called with irq disabled or enabled. This has a small chance of causing A-A deadlocks and triggers lockdep splats. Use irqsave operations instead.

2020-09-01dm integrity: fix error reporting in bitmap mode after creationMikulas Patocka
The dm-integrity target did not report errors in bitmap mode just after creation. The reason is that the function integrity_recalc didn't clean up ic->recalc_bitmap as it proceeded with recalculation. Fix this by updating the bitmap accordingly -- the double shift serves to rounddown.
