If memory allocation fails, decrement ->tfm_count to avoid blocking future reads.

2026-02-28crypto: ccp - Fix use-after-free on error pathAlper Ak-1/+1
In the error path of sev_tsm_init_locked(), the code dereferences 't' after it has been freed with kfree(). The pr_err() statement attempts to access t->tio_en and t->tio_init_done after the memory has been released. Move the pr_err() call before kfree(t) to access the fields while the memory is still valid.

When SEV is disabled, the HV-Fixed page allocation call fails, which in turn causes SFS initialization to fail. Fix the HV-Fixed API so callers (for example, SFS) can use it even when SEV is disabled by performing normal page allocation and freeing.

2026-02-21Convert more 'alloc_obj' cases to default GFP_KERNEL argumentsLinus Torvalds-22/+11
This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2026-02-21Convert 'alloc_obj' family to use the new default GFP_KERNEL argumentLinus Torvalds-111/+111
This was done entirely with mindless brute force, using git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' | xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/' to convert the new alloc_obj() users that had a simple GFP_KERNEL argument to just drop that argument. Note that due to the extreme simplicity of the scripting, any slightly more complex cases spread over multiple lines would not be triggered: they definitely exist, but this covers the vast bulk of the cases, and the resulting diff is also then easier to check automatically. For the same reason the 'flex' versions will be done as a separate conversion. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2026-02-21treewide: Replace kmalloc with kmalloc_obj for non-scalar typesKees Cook-176/+172
This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook <kees@kernel.org>

2026-01-31crypto: caam - fix netdev memory leak in dpaa2_caam_probeJianpeng Chang-12/+17
When commit 0e1a4d427f58 ("crypto: caam: Unembed net_dev structure in dpaa2") converted embedded net_device to dynamically allocated pointers, it added cleanup in dpaa2_dpseci_disable() but missed adding cleanup in dpaa2_dpseci_free() for error paths. This causes memory leaks when dpaa2_dpseci_dpio_setup() fails during probe due to DPIO devices not being ready yet. The kernel's deferred probe mechanism handles the retry successfully, but the netdevs allocated during the failed probe attempt are never freed, resulting in kmemleak reports showing multiple leaked netdev-related allocations all traced back to dpaa2_caam_probe(). Fix this by preserving the CPU mask of allocated netdevs during setup and using it for cleanup in dpaa2_dpseci_free(). This approach ensures that only the CPUs that actually had netdevs allocated will be cleaned up, avoiding potential issues with CPU hotplug scenarios.

2026-01-31crypto: hisilicon/qm - increase wait time for mailboxWeili Qian-10/+24
The device requires more time to process queue stop and function stop mailbox commands compared to other mailbox commands . In the current driver, the mailbox processing wait time for queue stop and function stop is less than the device timeout, which may cause the driver to incorrectly assume that the mailbox processing has failed. Therefore, the driver wait time for queue stop and function stop should be set to be greater than the device timeout. And PF and VF communication relies on mailbox, the communication wait time should also be modified.

2026-01-31crypto: hisilicon/qm - obtain the mailbox configuration at one timeWeili Qian-47/+86
The malibox needs to be triggered by a 128bit atomic operation. The reason is that the PF and VFs of the device share the mmio memory of the mailbox, and the mutex cannot lock mailbox operations in different functions, especially when passing through VFs to virtual machines. Currently, the write operation to the mailbox is already a 128-bit atomic write. The read operation also needs to be modified to a 128-bit atomic read. Since there is no general 128-bit IO memory access API in the current ARM64 architecture, and the stp and ldp instructions do not guarantee atomic access to device memory, they cannot be extracted as a general API. Therefore, the 128-bit atomic read and write operations need to be implemented in the driver.

Before sending the data via the mailbox to the hardware, to ensure that the data accessed by the hardware is the most up-to-date, a write barrier should be added before writing to the mailbox register. The current memory barrier is placed after writing to the register, the barrier order should be modified to be before writing to the register.

When the 8th bit of the capability register is 1, the lz4 algorithm will register to crypto acomp, and the window length is configured to 16K by default.

2026-01-30crypto/ccp: Allow multiple streams on the same root bridgeAlexey Kardashevskiy-2/+1
With SEV-TIO the low-level TSM driver is responsible for allocating a Stream ID. The Stream ID needs to be unique within each IDE partner port. Fix the Stream ID selection to reuse the host bridge stream resource id which is a pool of 256 ids per host bridge on AMD platforms. Otherwise, only one device per-host bridge can establish Selective Stream IDE.

EIP93 has an options register. This register indicates which crypto algorithms are implemented in silicon. Supported algorithms are registered on this basis. Unregister algorithms on the same basis.

Annotating a local pointer variable, which will be assigned with the kmalloc-family functions, with the `__cleanup(kfree)` attribute will make the address of the local variable, rather than the address returned by kmalloc, passed to kfree directly and lead to a crash due to invalid deallocation of stack address. According to other places in the repo, the correct usage should be `__free(kfree)`. The code coincidentally compiled because the parameter type `void *` of kfree is compatible with the desired type `struct { ... } **`.
