thermal: core: Allow thermal zones to tell the core to ignore them

2024-07-24T13:54:07Z

commit e528be3c87be953b73e7826a2d7e4b837cbad39d upstream. The iwlwifi wireless driver registers a thermal zone that is only needed when the network interface handled by it is up and it wants that thermal zone to be effectively ignored by the core otherwise. Before commit a8a261774466 ("thermal: core: Call monitor_thermal_zone() if zone temperature is invalid") that could be achieved by returning an error code from the thermal zone's .get_temp() callback because the core did not really handle errors returned by it almost at all. However, commit a8a261774466 made the core attempt to recover from the situation in which the temperature of a thermal zone cannot be determined due to errors returned by its .get_temp() and is always invalid from the core's perspective. That was done because there are thermal zones in which .get_temp() returns errors to start with due to some difficulties related to the initialization ordering, but then it will start to produce valid temperature values at one point. Unfortunately, the simple approach taken by commit a8a261774466, which is to poll the thermal zone periodically until its .get_temp() callback starts to return valid temperature values, is at odds with the special thermal zone in iwlwifi in which .get_temp() may always return an error because its network interface may always be down. If that happens, every attempt to invoke the thermal zone's .get_temp() callback resulting in an error causes the thermal core to print a dev_warn() message to the kernel log which is super-noisy. To address this problem, make the core handle the case in which .get_temp() returns 0, but the temperature value returned by it is not actually valid, in a special way. Namely, make the core completely ignore the invalid temperature value coming from .get_temp() in that case, which requires folding in update_temperature() into its caller and a few related changes. On the iwlwifi side, modify iwl_mvm_tzone_get_temp() to return 0 and put THERMAL_TEMP_INVALID into the temperature return memory location instead of returning an error when the firmware is not running or it is not of the right type. Also, to clearly separate the handling of invalid temperature values from the thermal zone initialization, introduce a special THERMAL_TEMP_INIT value specifically for the latter purpose.

io_uring: fix error pbuf checking

commit bcc87d978b834c298bbdd9c52454c5d0a946e97e upstream. Syz reports a problem, which boils down to NULL vs IS_ERR inconsistent error handling in io_alloc_pbuf_ring().

ASoC: cs35l56: Limit Speaker Volume to +12dB maximum

2024-07-24T13:54:07Z

commit 244389bd42870640c4b5ef672a360da329b579ed upstream. Change CS35L56_MAIN_RENDER_USER_VOLUME_MAX to 48, to limit the maximum value of the Speaker Volume control to +12dB. The minimum value is unchanged so that the default 0dB has the same integer control value. The original maximum of 400 (+100dB) was the largest value that can be mathematically handled by the DSP. The actual maximum amplification is +12dB.

cifs: Fix setting of zero_point after DIO write

2024-07-24T13:54:06Z

commit 61ea6b3a3104fcd66364282391dd2152bc4c129a upstream. At the moment, at the end of a DIO write, cifs calls netfs_resize_file() to adjust the size of the file if it needs it. This will reduce the zero_point (the point above which we assume a read will just return zeros) if it's more than the new i_size, but won't increase it. With DIO writes, however, we definitely want to increase it as we have clobbered the local pagecache and then written some data that's not available locally. Fix cifs to make the zero_point above the end of a DIO or unbuffered write. This fixes corruption seen occasionally with the generic/708 xfs-test. In that case, the read-back of some of the written data is being short-circuited and replaced with zeroes.

cifs: Fix server re-repick on subrequest retry

2024-07-24T13:54:06Z

commit de40579b903883274fe203865f29d66b168b7236 upstream. When a subrequest is marked for needing retry, netfs will call cifs_prepare_write() which will make cifs repick the server for the op before renegotiating credits; it then calls cifs_issue_write() which invokes smb2_async_writev() - which re-repicks the server. If a different server is then selected, this causes the increment of server->in_flight to happen against one record and the decrement to happen against another, leading to misaccounting. Fix this by just removing the repick code in smb2_async_writev(). As this is only called from netfslib-driven code, cifs_prepare_write() should always have been called first, and so server should never be NULL and the preparatory step is repeated in the event that we do a retry. The problem manifests as a warning looking something like: WARNING: CPU: 4 PID: 72896 at fs/smb/client/smb2ops.c:97 smb2_add_credits+0x3f0/0x9e0 [cifs] ...

commit ae4ccca47195332c69176b8615c5ee17efd30c46 upstream. There are common cases where copy_file_range can noisily log "source and target of copy not on same server" e.g. the mv command across mounts to two different server's shares.
