2021-06-08drm/vc4: fix vc4_atomic_commit_tail() logicMark Rutland
In vc4_atomic_commit_tail() we iterate of the set of old CRTCs, and attempt to wait on any channels which are still in use. When we iterate over the CRTCs, we have: * `i` - the index of the CRTC * `channel` - the channel a CRTC is using When we check the channel state, we consult: old_hvs_state->fifo_state[channel].in_use ... but when we wait for the channel, we erroneously wait on: old_hvs_state->fifo_state[i].pending_commit ... rather than: old_hvs_state->fifo_state[channel].pending_commit ... and this bogus access has been observed to result in boot-time hangs on some arm64 configurations, and can be detected using KASAN. FIx this by using the correct index. I've tested this on a Raspberry Pi 3 model B v1.2 with KASAN.

2021-06-08x86/ioremap: Map EFI-reserved memory as encrypted for SEVTom Lendacky
Some drivers require memory that is marked as EFI boot services data. In order for this memory to not be re-used by the kernel after ExitBootServices(), efi_mem_reserve() is used to preserve it by inserting a new EFI memory descriptor and marking it with the EFI_MEMORY_RUNTIME attribute. Under SEV, memory marked with the EFI_MEMORY_RUNTIME attribute needs to be mapped encrypted by Linux, otherwise the kernel might crash at boot like below: EFI Variables Facility v0.08 2004-May-17 general protection fault, probably for non-canonical address 0x3597688770a868b2: 0000 [#1] SMP NOPTI CPU: 13 PID: 1 Comm: swapper/0 Not tainted 5.12.4-2-default #1 openSUSE Tumbleweed Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 0.0.0 02/06/2015 RIP: 0010:efi_mokvar_entry_next [...] Call Trace: efi_mokvar_sysfs_init ? efi_mokvar_table_init do_one_initcall ? __kmalloc kernel_init_freeable ? rest_init kernel_init ret_from_fork Expand the __ioremap_check_other() function to additionally check for this other type of boot data reserved at runtime and indicate that it should be mapped encrypted for an SEV guest.

R-Car M3-W ES3.0 is marketed as R-Car M3-W+ (R8A77961), and has its own compatible value "renesas,r8a77961". Hence using soc_device_match() with soc_id = "r8a7796" and revision = "ES3.*" does not actually match running on an R-Car M3-W+ SoC. Fix this by matching with soc_id = "r8a77961" instead.

There are 2 issues on this machine, the 1st one is mic's plug/unplug can't be detected, that is because the mic is set to manual detecting mode, need to apply ALC255_FIXUP_XIAOMI_HEADSET_MIC to set it to auto detecting mode. The other one is headphone's plug/unplug can't be detected by pulseaudio, that is because the pulseaudio will use ucm2/sof-hda-dsp on this machine, and the ucm2 only handle 'Headphone Jack', but on this machine the headphone's pincfg sets the location to Front, then the alsa mixer name is "Front Headphone Jack" instead of "Headphone Jack", so override the pincfg to change location to Left.

We discussed if that is really the right approach for quite a while now, but digging deeper into a bug report on arm turned out that this is actually horrible broken right now. The reason for this is that vmf_insert_mixed_prot() always tries to grab a reference to the underlaying page on architectures without ARCH_HAS_PTE_SPECIAL and as far as I can see also enabled GUP.

Add driver for TI SN65DSI83 Single-link DSI to Single-link LVDS bridge and TI SN65DSI84 Single-link DSI to Dual-link or 2x Single-link LVDS bridge. TI SN65DSI85 is unsupported due to lack of hardware to test on, but easy to add. The driver operates the chip via I2C bus. Currently the LVDS clock are always derived from DSI clock lane, which is the usual mode of operation. Support for clock from external oscillator is not implemented, but it is easy to add if ever needed. Only RGB888 pixel format is implemented, the LVDS666 is not supported, but could be added if needed.

2021-06-08mac80211: fix deadlock in AP/VLAN handlingJohannes Berg
Syzbot reports that when you have AP_VLAN interfaces that are up and close the AP interface they belong to, we get a deadlock. No surprise - since we dev_close() them with the wiphy mutex held, which goes back into the netdev notifier in cfg80211 and tries to acquire the wiphy mutex there. To fix this, we need to do two things: 1) prevent changing iftype while AP_VLANs are up, we can't easily fix this case since cfg80211 already calls us with the wiphy mutex held, but change_interface() is relatively rare in drivers anyway, so changing iftype isn't used much (and userspace has to fall back to down/change/up anyway) 2) pull the dev_close() loop over VLANs out of the wiphy mutex section in the normal stop case Cc: stable@vger.kernel.org Reported-by: syzbot+452ea4fbbef700ff0a56@syzkaller.appspotmail.com Fixes: a05829a7222e ("cfg80211: avoid holding the RTNL when calling the driver") Link: https://lore.kernel.org/r/20210517160322.9b8f356c0222.I392cb0e2fa5a1a94cf2e637555d702c7e512c1ff@changeid Signed-off-by: Johannes Berg <johannes.berg@intel.com>

scsi_host_dev_release() only frees dev_name when host state is SHOST_CREATED. After host state has changed to SHOST_RUNNING, scsi_host_dev_release() no longer cleans up. Fix this by doing a put_device(&shost->shost_dev) in the failure path when host state is SHOST_RUNNING. Move get_device(&shost->shost_gendev) before device_add(&shost->shost_dev) so that scsi_host_cls_release() can do a put on this reference.

2021-06-07scsi: core: Fix failure handling of scsi_add_host_with_dma()Ming Lei
When scsi_add_host_with_dma() returns failure, the caller will call scsi_host_put(shost) to release everything allocated for this host instance. Consequently we can't also free allocated stuff in scsi_add_host_with_dma(), otherwise we will end up with a double free. Strictly speaking, host resource allocations should have been done in scsi_host_alloc(). However, the allocations may need information which is not yet provided by the driver when that function is called. So leave the allocations where they are but rely on host device's release handler to free resources.

2021-06-07scsi: core: Fix error handling of scsi_host_alloc()Ming Lei
After device is initialized via device_initialize(), or its name is set via dev_set_name(), the device has to be freed via put_device(). Otherwise device name will be leaked because it is allocated dynamically in dev_set_name(). Fix the leak by replacing kfree() with put_device(). Since scsi_host_dev_release() properly handles IDA and kthread removal, remove special-casing these from the error handling as well.

When calling xsk_socket__create_shared(), the logic at line 1097 marks a boolean flag true within the xsk_umem structure to track setup progress in order to support multiple calls to the function. However, instead of marking umem->tx_ring_setup_done, the code incorrectly sets umem->rx_ring_setup_done. This leads to improper behaviour when creating and destroying xsk and umem structures.

2021-06-07mlxsw: reg: Spectrum-3: Enforce lowest max-shaper burst size of 11Petr Machata
A max-shaper is the HW component responsible for delaying egress traffic above a configured transmission rate. Burst size is the amount of traffic that is allowed to pass without accounting. The burst size value needs to be such that it can be expressed as 2^BS * 512 bits, where BS lies in a certain ASIC-dependent range. mlxsw enforces that this holds before attempting to configure the shaper. The assumption for Spectrum-3 was that the lower limit of BS would be 5, like for Spectrum-1. But as of now, the limit is still 11. Therefore fix the driver accordingly, so that incorrect values are rejected early with a proper message.

2021-06-07afs: Fix partial writeback of large files on fsync and closeMarc Dionne
In commit e87b03f5830e ("afs: Prepare for use of THPs"), the return value for afs_write_back_from_locked_page was changed from a number of pages to a length in bytes. The loop in afs_writepages_region uses the return value to compute the index that will be used to find dirty pages in the next iteration, but treats it as a number of pages and wrongly multiplies it by PAGE_SIZE. This gives a very large index value, potentially skipping any dirty data that was not covered in the first pass, which is limited to 256M. This causes fsync(), and indirectly close(), to only do a partial writeback of a large file's dirty data. The rest is eventually written back by background threads after dirty_expire_centisecs.
