git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull trace ring buffer fixes from Steven Rostedt: - Enable resize on mmap() error When a process mmaps a ring buffer, its size is locked and resizing is disabled. But if the user passes in a wrong parameter, the mmap() can fail after the resize was disabled and the mmap() exits with error without reenabling the ring buffer resize. This prevents the ring buffer from ever being resized after that. Reenable resizing of the ring buffer on mmap() error. - Have resizing return proper error and not always -ENOMEM If the ring buffer is mmapped by one task and another task tries to resize the buffer it will error with -ENOMEM. This is confusing to the user as there may be plenty of memory available. Have it return the error that actually happens (in this case -EBUSY) where the user can understand why the resize failed. - Test the sub-buffer array to validate persistent memory buffer On boot up, the initialization of the persistent memory buffer will do a validation check to see if the content of the data is valid, and if so, it will use the memory as is, otherwise it re-initializes it. There's meta data in this persistent memory that keeps track of which sub-buffer is the reader page and an array that states the order of the sub-buffers. The values in this array are indexes into the sub-buffers. The validator checks to make sure that all the entries in the array are within the sub-buffer list index, but it does not check for duplications. While working on this code, the array got corrupted and had duplicates, where not all the sub-buffers were accounted for. This passed the validator as all entries were valid, but the link list was incorrect and could have caused a crash. The corruption only produced incorrect data, but it could have been more severe. To fix this, create a bitmask that covers all the sub-buffer indexes and set it to all zeros. While iterating the array checking the values of the array content, have it set a bit corresponding to the index in the array. If the bit was already set, then it is a duplicate and mark the buffer as invalid and reset it. - Prevent mmap()ing persistent ring buffer The persistent ring buffer uses vmap() to map the persistent memory. Currently, the mmap() logic only uses virt_to_page() to get the page from the ring buffer memory and use that to map to user space. This works because a normal ring buffer uses alloc_page() to allocate its memory. But because the persistent ring buffer use vmap() it causes a kernel crash. Fixing this to work with vmap() is not hard, but since mmap() on persistent memory buffers never worked, just have the mmap() return -ENODEV (what was returned before mmap() for persistent memory ring buffers, as they never supported mmap. Normal buffers will still allow mmap(). Implementing mmap() for persistent memory ring buffers can wait till the next merge window. - Fix polling on persistent ring buffers There's a "buffer_percent" option (default set to 50), that is used to have reads of the ring buffer binary data block until the buffer fills to that percentage. The field "pages_touched" is incremented every time a new sub-buffer has content added to it. This field is used in the calculations to determine the amount of content is in the buffer and if it exceeds the "buffer_percent" then it will wake the task polling on the buffer. As persistent ring buffers can be created by the content from a previous boot, the "pages_touched" field was not updated. This means that if a task were to poll on the persistent buffer, it would block even if the buffer was completely full. It would block even if the "buffer_percent" was zero, because with "pages_touched" as zero, it would be calculated as the buffer having no content. Update pages_touched when initializing the persistent ring buffer from a previous boot. * tag 'trace-ring-buffer-v6.14-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: ring-buffer: Update pages_touched to reflect persistent buffer content tracing: Do not allow mmap() of persistent ring buffer ring-buffer: Validate the persistent meta data subbuf array tracing: Have the error of __tracing_resize_ring_buffer() passed to user ring-buffer: Unlock resize on mmap error
2025-02-15ring-buffer: Update pages_touched to reflect persistent buffer contentSteven Rostedt
The pages_touched field represents the number of subbuffers in the ring buffer that have content that can be read. This is used in accounting of "dirty_pages" and "buffer_percent" to allow the user to wait for the buffer to be filled to a certain amount before it reads the buffer in blocking mode. The persistent buffer never updated this value so it was set to zero, and this accounting would take it as it had no content. This would cause user space to wait for content even though there's enough content in the ring buffer that satisfies the buffer_percent.

It is rather trivial to allow this, but for now just disable mmap() of instances that have their ring buffer from the reserve_mem option. If an mmap() is performed on a persistent buffer it will return -ENODEV just like it would if the .mmap field wasn't defined in the file_operations structure.

2025-02-15tegra210-adma: fix 32-bit x86 buildLinus Torvalds
The Tegra210 Audio DMA controller driver did a plain divide: page_no = (res_page->start - res_base->start) / cdata->ch_base_offset; which causes problems on 32-bit x86 configurations that have 64-bit resource sizes: x86_64-linux-ld: drivers/dma/tegra210-adma.o: in function `tegra_adma_probe': tegra210-adma.c:(.text+0x1322): undefined reference to `__udivdi3' because gcc doesn't generate the trivial code for a 64-by-32 divide, turning it into a function call to do a full 64-by-64 divide. And the kernel intentionally doesn't provide that helper function, because 99% of the time all you want is the narrower version. Of course, tegra210 is a 64-bit architecture and the 32-bit x86 build is purely for build testing, so this really is just about build coverage failure. But build coverage is good. Side note: div_u64() would be suboptimal if you actually have a 32-bit resource_t, so our "helper" for divides are admittedly making it harder than it should be to generate good code for all the possible cases. At some point, I'll consider 32-bit x86 so entirely legacy that I can't find it in myself to care any more, and we'll just add the __udivdi3 library function. But for now, the right thing to do is to use "div_u64()" to show that you know that you are doing the simpler divide with a 32-bit number. And the build error enforces that. While fixing the build issue, also check for division-by-zero, and for overflow. Which hopefully cannot happen on real production hardware, but the value of 'ch_base_offset' can definitely be zero in other places.

2025-02-14alpha: make stack 16-byte aligned (most cases)Ivan Kokshaysky
The problem is that GCC expects 16-byte alignment of the incoming stack since early 2004, as Maciej found out [1]: Having actually dug speculatively I can see that the psABI was changed in GCC 3.5 with commit e5e10fb4a350 ("re PR target/14539 (128-bit long double improperly aligned)") back in Mar 2004, when the stack pointer alignment was increased from 8 bytes to 16 bytes, and arch/alpha/kernel/entry.S has various suspicious stack pointer adjustments, starting with SP_OFF which is not a whole multiple of 16. Also, as Magnus noted, "ALPHA Calling Standard" [2] required the same: D.3.1 Stack Alignment This standard requires that stacks be octaword aligned at the time a new procedure is invoked. However: - the "normal" kernel stack is always misaligned by 8 bytes, thanks to the odd number of 64-bit words in 'struct pt_regs', which is the very first thing pushed onto the kernel thread stack; - syscall, fault, interrupt etc. handlers may, or may not, receive aligned stack depending on numerous factors. Somehow we got away with it until recently, when we ended up with a stack corruption in kernel/smp.c:smp_call_function_single() due to its use of 32-byte aligned local data and the compiler doing clever things allocating it on the stack. This adds padding between the PAL-saved and kernel-saved registers so that 'struct pt_regs' have an even number of 64-bit words. This makes the stack properly aligned for most of the kernel code, except two handlers which need special threatment.

2025-02-14ring-buffer: Validate the persistent meta data subbuf arraySteven Rostedt
The meta data for a mapped ring buffer contains an array of indexes of all the subbuffers. The first entry is the reader page, and the rest of the entries lay out the order of the subbuffers in how the ring buffer link list is to be created. The validator currently makes sure that all the entries are within the range of 0 and nr_subbufs. But it does not check if there are any duplicates. While working on the ring buffer, I corrupted this array, where I added duplicates. The validator did not catch it and created the ring buffer link list on top of it. Luckily, the corruption was only that the reader page was also in the writer path and only presented corrupted data but did not crash the kernel. But if there were duplicates in the writer side, then it could corrupt the ring buffer link list and cause a crash. Create a bitmask array with the size of the number of subbuffers. Then clear it. When walking through the subbuf array checking to see if the entries are within the range, test if its bit is already set in the subbuf_mask. If it is, then there is duplicates and fail the validation. If not, set the corresponding bit and continue.

2025-02-14tracing: Have the error of __tracing_resize_ring_buffer() passed to userSteven Rostedt
Currently if __tracing_resize_ring_buffer() returns an error, the tracing_resize_ringbuffer() returns -ENOMEM. But it may not be a memory issue that caused the function to fail. If the ring buffer is memory mapped, then the resizing of the ring buffer will be disabled. But if the user tries to resize the buffer, it will get an -ENOMEM returned, which is confusing because there is plenty of memory. The actual error returned was -EBUSY, which would make much more sense to the user.

2025-02-14partitions: mac: fix handling of bogus partition tableJann Horn
Fix several issues in partition probing: - The bailout for a bad partoffset must use put_dev_sector(), since the preceding read_part_sector() succeeded. - If the partition table claims a silly sector size like 0xfff bytes (which results in partition table entries straddling sector boundaries), bail out instead of accessing out-of-bounds memory. - We must not assume that the partition table contains proper NUL termination - use strnlen() and strncmp() instead of strlen() and strcmp().

2025-02-14iommu/vt-d: Make intel_iommu_drain_pasid_prq() cover faults for RIDLu Baolu
This driver supports page faults on PCI RID since commit <9f831c16c69e> ("iommu/vt-d: Remove the pasid present check in prq_event_thread") by allowing the reporting of page faults with the pasid_present field cleared to the upper layer for further handling. The fundamental assumption here is that the detach or replace operations act as a fence for page faults. This implies that all pending page faults associated with a specific RID or PASID are flushed when a domain is detached or replaced from a device RID or PASID. However, the intel_iommu_drain_pasid_prq() helper does not correctly handle faults for RID. This leads to faults potentially remaining pending in the iommu hardware queue even after the domain is detached, thereby violating the aforementioned assumption. Fix this issue by extending intel_iommu_drain_pasid_prq() to cover faults for RID.
