blk-cgroup: fix list corruption from reorder of WRITE ->lqueued
__blkcg_rstat_flush() can be run anytime, especially when blk_cgroup_bio_start
is being executed.
If WRITE of `->lqueued` is re-ordered with READ of 'bisc->lnode.next' in
the loop of __blkcg_rstat_flush(), `next_bisc` can be assigned with one
stat instance being added in blk_cgroup_bio_start(), then the local
list in __blkcg_rstat_flush() could be corrupted.
Fix the issue by adding one barrier.

nbd: Fix signal handling
Both nbd_send_cmd() and nbd_handle_cmd() return either a negative error
number or a positive blk_status_t value. nbd_queue_rq() converts these
return values into a blk_status_t value. There is a bug in the conversion
code: if nbd_send_cmd() returns BLK_STS_RESOURCE, nbd_queue_rq() should
return BLK_STS_RESOURCE instead of BLK_STS_OK. Fix this, move the
conversion code into nbd_handle_cmd() and fix the remaining sparse warnings.
This patch fixes the following sparse warnings:

brd: implement discard support
The ramdisk memory utilization can only go up when data is written to new pages. Implement discard to provide the possibility to reduce memory usage for pages no longer in use. Aligned discards will free the associated pages, if any, and determinisitically return zeroed data until written again.

ublk_drv: set DMA alignment mask to 3
By default, this will be 511, as that's the block layer default. But drivers these days can support memory alignments that aren't tied to the sector sizes, instead just being limited by what the DMA engine supports. An example is NVMe, where it's generally set to a 32-bit or 64-bit boundary. As ublk itself doesn't really care, just set it low enough that we don't run into issues with NVMe where the required O_DIRECT memory alignment is now more restrictive on ublk than it is on the underlying device. This was triggered by spurious -EINVAL returns on O_DIRECT IO on a setup with ublk managing NVMe devices, which previously worked just fine on the NVMe device itself. With the alignment relaxed, the test works fine. Reviewed-by: Ming Lei <ming.lei@redhat.com> Signed-off-by: Jens Axboe <axboe@kernel.dk> |

MSG_ZEROCOPY already does this with send(2) and sendmsg(2), but the io_uring side did not. In local testing, the crossover point for send zerocopy being faster is now around 3000 byte packets, and it performs better than the sync syscall variants as well. This feature relies on a shared branch with net-next, which was pulled into both branches. - Unification of how async preparation is done across opcodes. Previously, opcodes that required extra memory for async retry would allocate that as needed, using on-stack state until that was the case. If async retry was needed, the on-stack state was adjusted appropriately for a retry and then copied to the allocated memory. This led to some fragile and ugly code, particularly for read/write handling, and made storage retries more difficult than they needed to be. Allocate the memory upfront, as it's cheap from our pools, and use that state consistently both initially and also from the retry side. - Move away from using remap_pfn_range() for mapping the rings. This is really not the right interface to use and can cause lifetime issues or leaks. Additionally, it means the ring sq/cq arrays need to be physically contigious, which can cause problems in production with larger rings when services are restarted, as memory can be very fragmented at that point. Move to using vm_insert_page(s) for the ring sq/cq arrays, and apply the same treatment to mapped ring provided buffers. This also helps unify the code we have dealing with allocating and mapping memory. Hard to see in the diffstat as we're adding a few features as well, but this kills about ~400 lines of code from the codebase as well. - Add support for bundles for send/recv. When used with provided buffers, bundles support sending or receiving more than one buffer at the time, improving the efficiency by only needing to call into the networking stack once for multiple sends or receives. - Tweaks for our accept operations, supporting both a DONTWAIT flag for skipping poll arm and retry if we can, and a POLLFIRST flag that the application can use to skip the initial accept attempt and rely purely on poll for triggering the operation. Both of these have identical flags on the receive side already. - Make the task_work ctx locking unconditional. We had various code paths here that would do a mix of lock/trylock and set the task_work state to whether or not it was locked. All of that goes away, we lock it unconditionally and get rid of the state flag indicating whether it's locked or not. The state struct still exists as an empty type, can go away in the future. - Add support for specifying NOP completion values, allowing it to be used for error handling testing. - Use set/test bit for io-wq worker flags. Not strictly needed, but also doesn't hurt and helps silence a KCSAN warning. - Cleanups for io-wq locking and work assignments, closing a tiny race where cancelations would not be able to find the work item reliably. - Misc fixes, cleanups, and improvements * tag 'for-6.10/io_uring-20240511' of git://git.kernel.dk/linux: (97 commits) io_uring: support to inject result for NOP io_uring: fail NOP if non-zero op flags is passed in io_uring/net: add IORING_ACCEPT_POLL_FIRST flag io_uring/net: add IORING_ACCEPT_DONTWAIT flag io_uring/filetable: don't unnecessarily clear/reset bitmap io_uring/io-wq: Use set_bit() and test_bit() at worker->flags io_uring/msg_ring: cleanup posting to IOPOLL vs !IOPOLL ring io_uring: Require zeroed sqe->len on provided-buffers send io_uring/notif: disable LAZY_WAKE for linked notifs io_uring/net: fix sendzc lazy wake polling io_uring/msg_ring: reuse ctx->submitter_task read using READ_ONCE instead of re-reading it io_uring/rw: reinstate thread check for retries io_uring/notif: implement notification stacking io_uring/notif: simplify io_notif_flush() net: add callback for setting a ubuf_info to skb net: extend ubuf_info callback to ops structure io_uring/net: support bundles for recv io_uring/net: support bundles for send io_uring/kbuf: add helpers for getting/peeking multiple buffers io_uring/net: add provided buffer support for IORING_OP_SEND ... |

Hi,
These are the changes for the TPM driver with a single major new feature: TPM bus encryption and integrity protection. The key pair on TPM side is generated from so called null random seed per power on of the machine [1]. This supports the TPM encryption of the hard drive by adding layer of protection against bus interposer attacks. Other than the pull request a few minor fixes and documentation for tpm_tis to clarify basics of TPM localities for future patch review discussions (will be extended and refined over times, just a seed).

The memcg hook changes are going through the mm tree due to dependencies. - Prevent stalls when reading /proc/slabinfo (Jianfeng Wang) This fixes the long-standing problem that can happen with workloads that have alloc/free patterns resulting in many partially used slabs (in e.g. dentry cache). Reading /proc/slabinfo will traverse the long partial slab list under spinlock with disabled irqs and thus can stall other processes or even trigger the lockup detection. The traversal is only done to count free objects so that <active_objs> column can be reported along with <num_objs>. To avoid affecting fast paths with another shared counter (attempted in the past) or complex partial list traversal schemes that allow rescheduling, the chosen solution resorts to approximation - when the partial list is over 10000 slabs long, we will only traverse first 5000 slabs from head and tail each and use the average of those to estimate the whole list. Both head and tail are used as the slabs near head to tend to have more free objects than the slabs towards the tail. It is expected the approximation should not break existing /proc/slabinfo consumers. The <num_objs> field is still accurate and reflects the overall kmem_cache footprint. The <active_objs> was already imprecise due to cpu and percpu-partial slabs, so can't be relied upon to determine exact cache usage. The difference between <active_objs> and <num_objs> is mainly useful to determine the slab fragmentation, and that will be possible even with the approximation in place. - Prevent allocating many slabs when a NUMA node is full (Chen Jun) Currently, on NUMA systems with a node under significantly bigger pressure than other nodes, the fallback strategy may result in each kmalloc_node() that can't be safisfied from the preferred node, to allocate a new slab on a fallback node, and not reuse the slabs already on that node's partial list. This is now fixed and partial lists of fallback nodes are checked even for kmalloc_node() allocations. It's still preferred to allocate a new slab on the requested node before a fallback, but only with a GFP_NOWAIT attempt, which will fail quickly when the node is under a significant memory pressure. - More SLAB removal related cleanups (Xiu Jianfeng, Hyunmin Lee) - Fix slub_kunit self-test with hardened freelists (Guenter Roeck) - Mark racy accesses for KCSAN (linke li) - Misc cleanups (Xiongwei Song, Haifeng Xu, Sangyun Kim)" * tag 'slab-for-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab: mm/slub: remove the check for NULL kmalloc_caches mm/slub: create kmalloc 96 and 192 caches regardless cache size order mm/slub: mark racy access on slab->freelist slub: use count_partial_free_approx() in slab_out_of_memory() slub: introduce count_partial_free_approx() slub: Set __GFP_COMP in kmem_cache by default mm/slub: remove duplicate initialization for early_kmem_cache_node_alloc() mm/slub: correct comment in do_slab_free() mm/slub, kunit: Use inverted data to corrupt kmem cache mm/slub: simplify get_partial_node() mm/slub: add slub_get_cpu_partial() helper mm/slub: remove the check of !kmem_cache_has_cpu_partial() mm/slub: Reduce memory consumption in extreme scenarios mm/slub: mark racy accesses on slab->slabs mm/slub: remove dummy slabinfo functions |

kcsan: Introduce __data_racy type qualifier
This commit adds a __data_racy type qualifier that enables kernel developers to inform KCSAN that a given variable is a shared variable without needing to mark each and every access. This allows pre-KCSAN code to be correctly (if approximately) instrumented withh very little effort, and also provides people reading the code a clear indication that the variable is in fact shared. In addition, it permits incremental transition to per-access KCSAN marking, so that (for example) a given subsystem can be transitioned one variable at a time, while avoiding large numbers of KCSAN warnings during this transition. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEbK7UrM+RBIrCoViJnr8S83LZ+4wFAmY+i+cTHHBhdWxtY2tA a2VybmVsLm9yZwAKCRCevxLzctn7jJQ1D/9eOBNKefU7duZgAOzUizPdxRvxKzPx UENz6DU/xXB+jcaWiRvdWyFgIFnUS/TaZcwtthXh4bV1I754dRFy8X9+/uHd8AVY MUwRkhY3Nie/MgkvLrEmMsfWn9zSUp0Pwq4dwFdhvb0aosFSn7PgtSrE62+RafpZ k1abEUa62MfSLJjJ7C8ThYk9broAgz37drloAStAr4PvrCM4JaoeChkStaAK80z1 qq3EblLtXlzKcW1UNkvsbTxcnv+quLsI4EHKSnN3O8l47/F/k52ENz5Qp1pYTOLk kO3IZjqFqnIH6Re5eHPA05cwQssJFvsB8gfB+g+kc2uOK/z7wwg0/gqf9SZyaosw ABoaxflfNE/mTzKVgob3wqGyhlsAE/R2k02yoMad4X78ATOi9RpjdH6xC4OOXYfV 4P8g2hGAHNR8UgYosXFx+YCu2ktGYyfsqTicMaaaECUfxFeJjJ1QqgwHYHADDDv/ x8UxggAco1jul+6fikPGnjDgBN5IJOwS26NEUguqAFqYMTF8OO/x6ag6cqG5nk3a b41GF4HEfoQtJduuOv8jVntyTRU7zbpH+AVuinQ1V34kpYp5fE75p30P4UUjMegA JaAoOeD9aebEUHHlujomaV/QKSHobYLmYp/ARe2QZjp7aiELcjvV/ThOdwRxGEZg Zl4qRaGc9YO/Ag== =f1gr -----END PGP SIGNATURE----- Merge tag 'kcsan.2024.05.10a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu Pull kcsan update from Paul McKenney: "Introduce __data_racy type qualifier This adds a __data_racy type qualifier that enables kernel developers to inform KCSAN that a given variable is a shared variable without needing to mark each and every access.

alpha: cleanups and build fixes
I had investigated dropping support for alpha EV5 and earlier a while ago after noticing that this is the only supported CPU family in the kernel without native byte access and that Debian has already dropped support for this generation last year [1] in order to improve performance for the newer machines. This topic came up again when Paul E. McKenney noticed that parts of the RCU code already rely on byte access and do not work on alpha EV5 reliably, so we decided on using my series to avoid the problem entirely. Al Viro did another series for alpha to address all the known build issues. I rebased his patches without any further changes and included it as a baseline for my work here to avoid conflicts and allow backporting the fixes to stable kernels for the now removed hardware support as well. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmY9z8gACgkQYKtH/8kJ UicPPw/+P++IYWKdWV5bFYZvK60yLNfnH9wqyog9vGJtlJg5Vj5olia9g5gM+TnN 2b7X8elEPcBrrGL1GbsUikt3WyUVr2IccKWXaM7Akpw5uuMDJRQiN+VefWuZ765y 0TzQ8aTSvyJPVX9GOA/zdXq0L6+8k5EAVrW4+rChZRJnwiPUE5GTQqpDXPxsVBVy ZUkEQeXs3cs0VzPzGdxuakXosvBNppGRTAEbxV/1b3RQ2yp3wcSuShF3jd20l3Oo X/RdecQtkA6oJylXRCW59ShSKPscgLxAxpHQlo1apZpGiik3xbRfyrWrQR3Va+P7 z9D3mkigGEoyL8KgR4F6pVamZ9Uhcn3+kv3e/V0sxzorkiv2Ab+qW38U1osFTKrt /I/DX6kG8Dv8r6otadHsImWK+sMP2jBDNHNmZAOA+SK9GgZ3AnK6HVtjGISe3l2b tYcM/W3QQ+pjYNnnguksh1OIHM4cKD7BbxZ3YU6iQ5z3f5Rpu/1NTSt0OSGAwjEz DfSkDW4baS81cpHfA36TbG942Hv8asM9BqwASgYWAyFZzPBrGGYJWWXVnR33A8L2 HnMXjfueTtWJYCV71q9EboNtM8diVDXRdU4B0qrEYTf1TlsdVXReaFfJsR9y/wmQ 04DBRaH2CBnktAp5nZNpZr5bX2jnm+dqYRi+CMNQTl4Cr2DVq+0= =0Sgm -----END PGP SIGNATURE----- Merge tag 'asm-generic-alpha' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pull alpha updates from Arnd Bergmann: "I had investigated dropping support for alpha EV5 and earlier a while ago after noticing that this is the only supported CPU family in the kernel without native byte access and that Debian has already dropped support for this generation last year [1] in order to improve performance for the newer machines.

- Store AP Query Configuration Information in a static buffer
- Rework the AP initialization and add missing cleanups to the error path - Swap IRQ and AP bus/device registration to avoid race conditions - Export prot_virt_guest symbol - Introduce AP configuration changes notifier interface to facilitate modularization of the AP bus - Add CONFIG_AP kernel configuration option to allow modularization of the AP bus - Rework CONFIG_ZCRYPT_DEBUG kernel configuration option description and dependency and rename it to CONFIG_AP_DEBUG - Convert sprintf() and snprintf() to sysfs_emit() in CIO code - Adjust indentation of RELOCS command build step - Make crypto performance counters upward compatible - Convert make_page_secure() and gmap_make_secure() to use folio - Rework channel-utilization-block (CUB) handling in preparation of introducing additional CUBs - Use attribute groups to simplify registration, removal and extension of measurement-related channel-path sysfs attributes - Add a per-channel-path binary "ext_measurement" sysfs attribute that provides access to extended channel-path measurement data - Export measurement data for all channel-measurement-groups (CMG), not only for a specific ones. This enables support of new CMG data formats in userspace without the need for kernel changes - Add a per-channel-path sysfs attribute "speed_bps" that provides the operating speed in bits per second or 0 if the operating speed is not available - The CIO tracepoint subchannel-type field "st" is incorrectly set to the value of subchannel-enabled SCHIB "ena" field. Fix that - Do not forcefully limit vmemmap starting address to MAX_PHYSMEM_BITS - Consider the maximum physical address available to a DCSS segment (512GB) when memory layout is set up - Simplify the virtual memory layout setup by reducing the size of identity mapping vs vmemmap overlap - Swap vmalloc and Lowcore/Real Memory Copy areas in virtual memory. This will allow to place the kernel image next to kernel modules - Move everyting KASLR related from <asm/setup.h> to <asm/page.h> - Put virtual memory layout information into a structure to improve code generation - Currently __kaslr_offset is the kernel offset in both physical and virtual memory spaces. Uncouple these offsets to allow uncoupling of the addresses spaces - Currently the identity mapping base address is implicit and is always set to zero. Make it explicit by putting into __identity_base persistent boot variable and use it in proper context - Introduce .amode31 section start and end macros AMODE31_START and AMODE31_END - Introduce OS_INFO entries that do not reference any data in memory, but rather provide only values - Store virtual memory layout in OS_INFO.

As reported by Kernel Test Robot and Sean Christopherson, some tests fail since v6.9-rc1 . This is due to the use of vfork() which introduced some side effects. Similarly, while making it more generic, a previous commit made some Landlock file system tests flaky, and subject to the host's file system mount configuration.

selftests/harness: Handle TEST_F()'s explicit exit codes
If TEST_F() explicitly calls exit(code) with code different than 0, then
_metadata->exit_code is set to this code (e.g. KVM_ONE_VCPU_TEST()). We
need to keep in mind that _metadata->exit_code can be KSFT_SKIP while
the process exit code is 0.

selftests/harness: Fix vfork() side effects
Setting the time namespace with CLONE_NEWTIME returns -EUSERS if the
calling thread shares memory with another thread (because of the shared
vDSO), which is the case when it is created with vfork().
Fix pidfd_setns_test by replacing test harness's vfork() call with a
clone3() call with CLONE_VFORK, and an explicit sharing of the
_metadata and self objects.
Replace _metadata->teardown_parent with a new FIXTURE_TEARDOWN_PARENT()
helper that can replace FIXTURE_TEARDOWN(). This is a cleaner approach
and it enables to selectively share the fixture data between the child
process running tests and the parent process running the fixture
teardown. This also avoids updating several tests to not rely on the
self object's copy-on-write property (e.g. storing the returned value of
a fork() call).
