2024-01-27erofs: relaxed temporary buffers allocation on readaheadChunhai Guo
Even with inplace decompression, sometimes very few temporary buffers may be still needed for a single decompression shot (e.g. 16 pages for 64k sliding window or 4 pages for 16k sliding window). In low-memory scenarios, it would be better to try to allocate with GFP_NOWAIT on readahead first. That can help reduce the time spent on page allocation under durative memory pressure. Here are detailed performance numbers under multi-app launch benchmark workload [1] on ARM64 Android devices (8-core CPU and 8GB of memory) running a 5.15 LTS kernel with EROFS of 4k pclusters: +----------------------------------------------+ | LZ4 | vanilla | patched | diff | |----------------+---------+---------+---------| | Average (ms) | 3364 | 2684 | -20.21% | [64k sliding window] |----------------+---------+---------+---------| | Average (ms) | 2079 | 1610 | -22.56% | [16k sliding window] +----------------------------------------------+ The total size of system images for 4k pclusters is almost unchanged: (64k sliding window) 9,117,044 KB (16k sliding window) 9,113,096 KB Therefore, in addition to switch the sliding window from 64k to 16k, after applying this patch, it can eventually save 52.14% (3364 -> 1610) on average with no memory reservation. That is particularly useful for embedded devices with limited resources.

2024-01-26lsm: fix the logic in security_inode_getsecctx()Ondrej Mosnacek
The inode_getsecctx LSM hook has previously been corrected to have -EOPNOTSUPP instead of 0 as the default return value to fix BPF LSM behavior. However, the call_int_hook()-generated loop in security_inode_getsecctx() was left treating 0 as the neutral value, so after an LSM returns 0, the loop continues to try other LSMs, and if one of them returns a non-zero value, the function immediately returns with said value. So in a situation where SELinux and the BPF LSMs registered this hook, -EOPNOTSUPP would be incorrectly returned whenever SELinux returned 0. Fix this by open-coding the call_int_hook() loop and making it use the correct LSM_RET_DEFAULT() value as the neutral one, similar to what other hooks do.

commit 056bce63c469 ("bnxt_en: Make PTP TX timestamp HWRM query silent") changed a netdev_err() to netdev_WARN_ONCE(). netdev_WARN_ONCE() is it generates a kernel WARNING, which is bad, for the following reasons: * You do not a kernel warning if the firmware queries are late * In busy networks, timestamp query failures fairly regularly * A WARNING message doesn't bring much value, since the code path is clear.

2024-01-26net/smc: fix incorrect SMC-D link group matching logicWen Gu
The logic to determine if SMC-D link group matches is incorrect. The correct logic should be that it only returns true when the GID is the same, and the SMC-D device is the same and the extended GID is the same (in the case of virtual ISM). It can be fixed by adding brackets around the conditional (or ternary) operator expression. But for better readability and maintainability, it has been changed to an if-else statement.

2024-01-26hwmon: (pmbus/mp2975) Fix driver initialization for MP2975 deviceKonstantin Aladyshev
The commit 1feb31e810b0 ("hwmon: (pmbus/mp2975) Simplify VOUT code") has introduced a bug that makes it impossible to initialize MP2975 device: """ mp2975 5-0020: Failed to identify chip capabilities i2c i2c-5: new_device: Instantiated device mp2975 at 0x20 i2c i2c-5: delete_device: Deleting device mp2975 at 0x20 """ Since the 'read_byte_data' function was removed from the 'pmbus_driver_info ' structure the driver no longer reports correctly that VOUT mode is direct. Therefore 'pmbus_identify_common' fails with error, making it impossible to initialize the device. Restore 'read_byte_data' function to fix the issue. Tested: - before: it is not possible to initialize MP2975 device with the 'mp2975' driver, - after: 'mp2975' correctly initializes MP2975 device and all sensor data is correct.
