Pull compute express link (cxl) updates from Dave Jiang: "Major changes address HDM decoder initialization from DVSEC ranges, refactoring the code related to cxl mailboxes to be independent of the memory devices, and adding support for shared upstream link access_coordinate calculation, as well as a change to remove locking from memory notifier callback. In addition, a number of misc cleanups and refactoring of the code are also included. Address HDM decoder initialization from DVSEC ranges: - Only register non-zero DVSEC ranges - Remove duplicate implementation of waiting for memory_info_valid - Simplify the checking of mem_enabled in cxl_hdm_decode_init() Refactor the code related to cxl mailboxes to be independent of the memory devices: - Move cxl headers in include/linux/ to include/cxl - Move all mailbox related data to 'struct cxl_mailbox' - Refactor mailbox APIs with 'struct cxl_mailbox' as input instead of memory device state Add support for shared upstream link access_coordinate calculation for configurations that have multiple targets under a switch or a root port where the aggregated bandwidth can be greater than the upstream link of the switch/RP upstream link: - Preserve the CDAT access_coordinate from an endpoint - Add the support for shared upstream link access_coordinate calculation - Add documentation to explain how the calculations are done Remove locking from memory notifier callback. Misc cleanups: - Convert devm_cxl_add_root() to return using ERR_CAST() - cxl_test use dev_is_platform() instead of open coding - Remove duplicate include of header core.h in core/cdat.c - use scoped resource management to drop put_device() for cxl_port - Use scoped_guard to drop device_lock() for cxl_port - Refactor __devm_cxl_add_port() to drop gotos - Rename cxl_setup_parent_dport to cxl_dport_init_aer and cxl_dport_map_regs() to cxl_dport_map_ras() - Refactor cxl_dport_init_aer() to be more concise - Remove duplicate host_bridge->native_aer checking in cxl_dport_init_ras_reporting() - Fix comment for cxl_query_cmd()" * tag 'cxl-for-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl: (21 commits) cxl: Add documentation to explain the shared link bandwidth calculation cxl: Calculate region bandwidth of targets with shared upstream link cxl: Preserve the CDAT access_coordinate for an endpoint cxl: Fix comment regarding cxl_query_cmd() return data cxl: Convert cxl_internal_send_cmd() to use 'struct cxl_mailbox' as input cxl: Move mailbox related bits to the same context cxl: move cxl headers to new include/cxl/ directory cxl/region: Remove lock from memory notifier callback cxl/pci: simplify the check of mem_enabled in cxl_hdm_decode_init() cxl/pci: Check Mem_info_valid bit for each applicable DVSEC cxl/pci: Remove duplicated implementation of waiting for memory_info_valid cxl/pci: Fix to record only non-zero ranges cxl/pci: Remove duplicate host_bridge->native_aer checking cxl/pci: cxl_dport_map_rch_aer() cleanup cxl/pci: Rename cxl_setup_parent_dport() and cxl_dport_map_regs() cxl/port: Refactor __devm_cxl_add_port() to drop goto pattern cxl/port: Use scoped_guard()/guard() to drop device_lock() for cxl_port cxl/port: Use __free() to drop put_device() for cxl_port cxl: Remove duplicate included header file core.h tools/testing/cxl: Use dev_is_platform() ...

This set is the one that caused the most delay on my side, due to lots of last-minute reports of problems in the async shutdown feature that was added. In the end, I've reverted all of the patches in that series so we are back to "normal" and the patch set is being reworked for the next merge window. Other than the async shutdown patches that were reverted, included in here are: - minor driver core cleanups - minor driver core bus and class api cleanups and simplifications for some callbacks - some const markings of structures - other even more minor cleanups All of these, including the last minute reverts, have been in linux-next, but all of the reports of problems in linux-next were before the reverts happened.

no_llseek had been defined to NULL two years ago, in commit 868941b1 ("fs: remove no_llseek") To quote that commit, At -rc1 we'll need do a mechanical removal of no_llseek - git grep -l -w no_llseek | grep -v porting.rst | while read i; do sed -i '/\<no_llseek\>/d' $i done would do it. Unfortunately, that hadn't been done. Linus, could you do that now, so that we could finally put that thing to rest? All instances are of the form .llseek = no_llseek, so it's obviously safe.

So the error log will trigger the above uninit-value access. The error log is out-of-date since get_blocks() was removed long time ago. And the error code will be logged in ocfs2_extent_map_get_blocks() once ocfs2_get_cluster() fails, so fix this by only logging inode and block.

Currently, there is an assembler message when generating kernel/bpf/core.o under CONFIG_OBJTOOL with LoongArch compiler toolchain: Warning: setting incorrect section attributes for .rodata..c_jump_table This is because the section ".rodata..c_jump_table" should be readonly, but there is a "W" (writable) part of the flags: $ readelf -S kernel/bpf/core.o | grep -A 1 "rodata..c" [34] .rodata..c_j[...] PROGBITS 0000000000000000 0000d2e0 0000000000000800 0000000000000000 WA 0 0 8 There is no above issue on x86 due to the generated section flag is only "A" (allocatable). In order to silence the warning on LoongArch, specify the attribute like ".rodata..c_jump_table,\"a\",@progbits #" explicitly, then the section attribute of ".rodata..c_jump_table" must be readonly in the kernel/bpf/core.o file. Before: $ objdump -h kernel/bpf/core.o | grep -A 1 "rodata..c" 21 .rodata..c_jump_table 00000800 0000000000000000 0000000000000000 0000d2e0 2**3 CONTENTS, ALLOC, LOAD, RELOC, DATA After: $ objdump -h kernel/bpf/core.o | grep -A 1 "rodata..c" 21 .rodata..c_jump_table 00000800 0000000000000000 0000000000000000 0000d2e0 2**3 CONTENTS, ALLOC, LOAD, RELOC, READONLY, DATA By the way, AFAICT, maybe the root cause is related with the different compiler behavior of various archs, so to some extent this change is a workaround for LoongArch, and also there is no effect for x86 which is the only port supported by objtool before LoongArch with this patch.

syzbot has found a possible deadlock in ocfs2_get_system_file_inode [1]. The scenario is depicted here, CPU0 CPU1 lock(&ocfs2_file_ip_alloc_sem_key); lock(&osb->system_file_mutex); lock(&ocfs2_file_ip_alloc_sem_key); lock(&osb->system_file_mutex); The function calls which could lead to this are: CPU0 ocfs2_mknod - lock(&ocfs2_file_ip_alloc_sem_key); . . . ocfs2_get_system_file_inode - lock(&osb->system_file_mutex); CPU1 - ocfs2_fill_super - lock(&osb->system_file_mutex); . . . ocfs2_read_virt_blocks - lock(&ocfs2_file_ip_alloc_sem_key); This issue can be resolved by making the down_read -> down_read_try in the ocfs2_read_virt_blocks.

One of our customers reported a crash and a corrupted ocfs2 filesystem. The crash was due to the detection of corruption. Upon troubleshooting, the fsck -fn output showed the below corruption [EXTENT_LIST_FREE] Extent list in owner 33080590 claims 230 as the next free chain record, but fsck believes the largest valid value is 227. Clamp the next record value? n The stat output from the debugfs.ocfs2 showed the following corruption where the "Next Free Rec:" had overshot the "Count:" in the root metadata block.

The issue was in the reflink workfow while reserving space for inline xattr. The problematic function is ocfs2_reflink_xattr_inline(). By the time this function is called the reflink tree is already recreated at the destination inode from the source inode. At this point, this function reserves space for inline xattrs at the destination inode without even checking if there is space at the root metadata block. It simply reduces the l_count from 243 to 227 thereby making space of 256 bytes for inline xattr whereas the inode already has extents beyond this index (in this case up to 230), thereby causing corruption. The fix for this is to reserve space for inline metadata at the destination inode before the reflink tree gets recreated. The customer has verified the fix.

The folio_try_get in memfd_alloc_folio is not necessary. Delete it, and delete the matching folio_put in memfd_pin_folios. This also avoids leaking a ref if the memfd_alloc_folio call to hugetlb_add_to_page_cache fails. That error path is also broken in a second way -- when its folio_put causes the ref to become 0, it will implicitly call free_huge_folio, but then the path *explicitly* calls free_huge_folio. Delete the latter.

When memfd_pin_folios -> memfd_alloc_folio creates a hugetlb page, the index is wrong. The subsequent call to filemap_get_folios_contig thus cannot find it, and fails, and memfd_pin_folios loops forever. To fix, adjust the index for the huge_page_order. memfd_alloc_folio also forgets to unlock the folio, so the next touch of the page calls hugetlb_fault which blocks forever trying to take the lock. Unlock it.

memfd_pin_folios followed by unpin_folios leaves resv_huge_pages elevated if the pages were not already faulted in. During a normal page fault, resv_huge_pages is consumed here: hugetlb_fault() alloc_hugetlb_folio() dequeue_hugetlb_folio_vma() dequeue_hugetlb_folio_nodemask() dequeue_hugetlb_folio_node_exact() free_huge_pages-- resv_huge_pages-- During memfd_pin_folios, the page is created by calling alloc_hugetlb_folio_nodemask instead of alloc_hugetlb_folio, and resv_huge_pages is not modified: memfd_alloc_folio() alloc_hugetlb_folio_nodemask() dequeue_hugetlb_folio_nodemask() dequeue_hugetlb_folio_node_exact() free_huge_pages-- alloc_hugetlb_folio_nodemask has other callers that must not modify resv_huge_pages. Therefore, to fix, define an alternate version of alloc_hugetlb_folio_nodemask for this call site that adjusts resv_huge_pages.

memfd_pin_folios followed by unpin_folios fails to restore free_huge_pages if the pages were not already faulted in, because the folio refcount for pages created by memfd_alloc_folio never goes to 0. memfd_pin_folios needs another folio_put to undo the folio_try_get below: memfd_alloc_folio() alloc_hugetlb_folio_nodemask() dequeue_hugetlb_folio_nodemask() dequeue_hugetlb_folio_node_exact() folio_ref_unfreeze(folio, 1); ; adds 1 refcount folio_try_get() ; adds 1 refcount hugetlb_add_to_page_cache() ; adds 512 refcount (on x86) With the fix, after memfd_pin_folios + unpin_folios, the refcount for the (unfaulted) page is 512, which is correct, as the refcount for a faulted unpinned page is 513.

Patch series "memfd-pin huge page fixes". Fix multiple bugs that occur when using memfd_pin_folios with hugetlb pages and THP. The hugetlb bugs only bite when the page is not yet faulted in when memfd_pin_folios is called. The THP bug bites when the starting offset passed to memfd_pin_folios is not huge page aligned. See the commit messages for details. This patch (of 5): memfd_pin_folios on memory backed by THP panics if the requested start offset is not huge page aligned: BUG: kernel NULL pointer dereference, address: 0000000000000036 RIP: 0010:filemap_get_folios_contig+0xdf/0x290 RSP: 0018:ffffc9002092fbe8 EFLAGS: 00010202 RAX: 0000000000000002 RBX: 0000000000000002 RCX: 0000000000000002 The fault occurs here, because xas_load returns a folio with value 2: filemap_get_folios_contig() for (folio = xas_load(&xas); folio && xas.xa_index <= end; folio = xas_next(&xas)) { ... if (!folio_try_get(folio)) <-- BOOM "2" is an xarray sibling entry. We get it because memfd_pin_folios does not round the indices passed to filemap_get_folios_contig to huge page boundaries for THP, so we load from the middle of a huge page range see a sibling. (It does round for hugetlbfs, at the is_file_hugepages test). To fix, if the folio is a sibling, then return the next index as the starting point for the next call to filemap_get_folios_contig.

SPLIT_PTE_PTLOCKS depends on "NR_CPUS >= 4". Unfortunately, that evaluates to true if there is no NR_CPUS configuration option. This results in CONFIG_SPLIT_PTE_PTLOCKS=y for mac_defconfig. This in turn causes the m68k "q800" and "virt" machines to crash in qemu if debugging options are enabled. Making CONFIG_SPLIT_PTE_PTLOCKS dependent on the existence of NR_CPUS does not work since a dependency on the existence of a numeric Kconfig entry always evaluates to false. Example: config HAVE_NO_NR_CPUS def_bool y depends on !NR_CPUS After adding this to a Kconfig file, "make defconfig" includes: $ grep NR_CPUS .config CONFIG_NR_CPUS=64 CONFIG_HAVE_NO_NR_CPUS=y Defining NR_CPUS for m68k does not help either since many architectures define NR_CPUS only for SMP configurations. Make SPLIT_PTE_PTLOCKS depend on SMP instead to solve the problem.

Pull staging driver updates from Greg KH: "Here is the big set of staging driver cleanups and removals for 6.12-rc1. Nothing exciting here, just slow, constant, forward progress in removing code and cleaning up some old drivers, along with removing one of them that was not being used anymore at all. In discussions with some developers this past week, even more deletions will be happening for the next major merge window, as we seems to have code here that obviously no one is using anymore. Along with the normal cleanups is the good vme_user code forward progress, the one major bright spot in the staging subsystem for code that people rely on, and is getting good development behind it.
