[PATCH] LoongArch: Prevent cond_resched() occurring within kernel-fpu

by Tianyang Zhang

When CONFIG_PREEMPT_COUNT is not configured (i.e. CONFIG_PREEMPT_NONE/ CONFIG_PREEMPT_VOLUNTARY), preempt_disable() / preempt_enable() merely acts as a barrier(). However, in these cases cond_resched() can still trigger a context switch and modify the CSR.EUEN, resulting in do_fpu() exception being activated within the kernel-fpu critical sections, as demonstrated in the following path: dcn32_calculate_wm_and_dlg() DC_FP_START() dcn32_calculate_wm_and_dlg_fpu() dcn32_find_dummy_latency_index_for_fw_based_mclk_switch() dcn32_internal_validate_bw() dcn32_enable_phantom_stream() dc_create_stream_for_sink() kzalloc(GFP_KERNEL) __kmem_cache_alloc_node() __cond_resched() DC_FP_END() This patch is similar to commit d021985 (x86/fpu: Improve crypto performance by making kernel-mode FPU reliably usable in softirqs). It uses local_bh_disable() instead of preempt_disable() for non-RT kernels so it can avoid the cond_resched() issue, and also extend the kernel-fpu application scenarios to the softirq context.

[PATCH 6.6.y] btrfs: always fallback to buffered write if the inode requires checksum

by Qu Wenruo

commit 968f19c5b1b7d5595423b0ac0020cc18dfed8cb5 upstream. [BUG] It is a long known bug that VM image on btrfs can lead to data csum mismatch, if the qemu is using direct-io for the image (this is commonly known as cache mode 'none'). [CAUSE] Inside the VM, if the fs is EXT4 or XFS, or even NTFS from Windows, the fs is allowed to dirty/modify the folio even if the folio is under writeback (as long as the address space doesn't have AS_STABLE_WRITES flag inherited from the block device). This is a valid optimization to improve the concurrency, and since these filesystems have no extra checksum on data, the content change is not a problem at all. But the final write into the image file is handled by btrfs, which needs the content not to be modified during writeback, or the checksum will not match the data (checksum is calculated before submitting the bio). So EXT4/XFS/NTRFS assume they can modify the folio under writeback, but btrfs requires no modification, this leads to the false csum mismatch. This is only a controlled example, there are even cases where multi-thread programs can submit a direct IO write, then another thread modifies the direct IO buffer for whatever reason. For such cases, btrfs has no sane way to detect such cases and leads to false data csum mismatch. [FIX] I have considered the following ideas to solve the problem: - Make direct IO to always skip data checksum This not only requires a new incompatible flag, as it breaks the current per-inode NODATASUM flag. But also requires extra handling for no csum found cases. And this also reduces our checksum protection. - Let hardware handle all the checksum AKA, just nodatasum mount option. That requires trust for hardware (which is not that trustful in a lot of cases), and it's not generic at all. - Always fallback to buffered write if the inode requires checksum This was suggested by Christoph, and is the solution utilized by this patch. The cost is obvious, the extra buffer copying into page cache, thus it reduces the performance. But at least it's still user configurable, if the end user still wants the zero-copy performance, just set NODATASUM flag for the inode (which is a common practice for VM images on btrfs). Since we cannot trust user space programs to keep the buffer consistent during direct IO, we have no choice but always falling back to buffered IO. At least by this, we avoid the more deadly false data checksum mismatch error.

[PATCH 5.10.y] of: module: add buffer overflow check in of_modalias()

by Uwe Kleine-König

From: Sergey Shtylyov <s.shtylyov(a)omp.ru> commit cf7385cb26ac4f0ee6c7385960525ad534323252 upstream. In of_modalias(), if the buffer happens to be too small even for the 1st snprintf() call, the len parameter will become negative and str parameter (if not NULL initially) will point beyond the buffer's end. Add the buffer overflow check after the 1st snprintf() call and fix such check after the strlen() call (accounting for the terminating NUL char).
