[PATCH 6.1.y] selftests/mm: Move default_huge_page_size to vm_util.c

by Leon Hwang

Fix the build error: map_hugetlb.c: In function 'main': map_hugetlb.c:79:25: warning: implicit declaration of function 'default_huge_page_size' [-Wimplicit-function-declaration] 79 | hugepage_size = default_huge_page_size(); | ^~~~~~~~~~~~~~~~~~~~~~ /usr/bin/ld: /tmp/ccYOogvJ.o: in function 'main': map_hugetlb.c:(.text+0x114): undefined reference to 'default_huge_page_size' According to the latest selftests, 'default_huge_page_size' has been moved to 'vm_util.c'. So fix the error by the same way.

[PATCH RESEND] fsi/core: fix error handling in fsi_slave_init()

by Ma Ke

Once cdev_device_add() failed, we should use put_device() to decrement reference count for cleanup. Or it could cause memory leak. Although operations in err_free_ida are similar to the operations in callback function fsi_slave_release(), put_device() is a correct handling operation as comments require when cdev_device_add() fails. As comment of device_add() says, 'if device_add() succeeds, you should call device_del() when you want to get rid of it. If device_add() has not succeeded, use only put_device() to drop the reference count'. Found by code review.

[PATCH] ksmbd: transport_ipc: validate payload size before reading handle

by Qianchang Zhao

handle_response() dereferences the payload as a 4-byte handle without verifying that the declared payload size is at least 4 bytes. A malformed or truncated message from ksmbd.mountd can lead to a 4-byte read past the declared payload size. Validate the size before dereferencing. This is a minimal fix to guard the initial handle read.

[PATCH v3 1/4] ASoC: qcom: sdw: fix memory leak for sdw_stream_runtime

by Srinivas Kandagatla

For some reason we endedup allocating sdw_stream_runtime for every cpu dai, this has two issues. 1. we never set snd_soc_dai_set_stream for non soundwire dai, which means there is no way that we can free this, resulting in memory leak 2. startup and shutdown callbacks can be called without hw_params callback called. This combination results in memory leak because machine driver sruntime array pointer is only set in hw_params callback. Fix this by 1. adding a helper function to get sdw_runtime for substream which can be used by shutdown callback to get hold of sruntime to free. 2. only allocate sdw_runtime for soundwire dais.

[PATCH] objtool/rust: add one more `noreturn` Rust function

by Miguel Ojeda

Between Rust 1.79 and 1.86, under `CONFIG_RUST_KERNEL_DOCTESTS=y`, `objtool` may report: rust/doctests_kernel_generated.o: warning: objtool: rust_doctest_kernel_alloc_kbox_rs_13() falls through to next function rust_doctest_kernel_alloc_kvec_rs_0() (as well as in rust_doctest_kernel_alloc_kvec_rs_0) due to calls to the `noreturn` symbol: core::option::expect_failed from code added in commits 779db37373a3 ("rust: alloc: kvec: implement AsPageIter for VVec") and 671618432f46 ("rust: alloc: kbox: implement AsPageIter for VBox"). Thus add the mangled one to the list so that `objtool` knows it is actually `noreturn`. This can be reproduced as well in other versions by tweaking the code, such as the latest stable Rust (1.90.0). Stable does not have code that triggers this, but it could have it in the future. Downstream forks could too. Thus tag it for backport. See commit 56d680dd23c3 ("objtool/rust: list `noreturn` Rust functions") for more details. Cc: stable(a)vger.kernel.org # Needed in 6.12.y and later.
