2019-01-09crypto: cavium/nitrox - fix a DMA pool free failureWenwen Wang
commit 7172122be6a4712d699da4d261f92aa5ab3a78b8 upstream. In crypto_alloc_context(), a DMA pool is allocated through dma_pool_alloc() to hold the crypto context. The meta data of the DMA pool, including the pool used for the allocation 'ndev->ctx_pool' and the base address of the DMA pool used by the device 'dma', are then stored to the beginning of the pool. These meta data are eventually used in crypto_free_context() to free the DMA pool through dma_pool_free(). However, given that the DMA pool can also be accessed by the device, a malicious device can modify these meta data, especially when the device is controlled to deploy an attack. This can cause an unexpected DMA pool free failure. To avoid the above issue, this patch introduces a new structure crypto_ctx_hdr and a new field chdr in the structure nitrox_crypto_ctx hold the meta data information of the DMA pool after the allocation. Note that the original structure ctx_hdr is not changed to ensure the compatibility.

As done treewide earlier, this catches several more open-coded allocation size calculations that were added to the kernel during the merge window. This performs the following mechanical transformations using Coccinelle: kvmalloc(a * b, ...) -> kvmalloc_array(a, b, ...) kvzalloc(a * b, ...) -> kvcalloc(a, b, ...) devm_kzalloc(..., a * b, ...) -> devm_kcalloc(..., a, b, ...)

When compiling with CONFIG_DEBUG_ATOMIC_SLEEP=y the mxs-dcp driver prints warnings such as: WARNING: CPU: 0 PID: 120 at kernel/sched/core.c:7736 __might_sleep+0x98/0x9c do not call blocking ops when !TASK_RUNNING; state=1 set at [<8081978c>] dcp_chan_thread_sha+0x3c/0x2ec The problem is that blocking ops will manipulate current->state themselves so it is not allowed to call them between set_current_state(TASK_INTERRUPTIBLE) and schedule(). Fix this by converting the per-chan mutex to a spinlock (it only protects tiny list ops anyway) and rearranging the wait logic so that callbacks are called current->state as TASK_RUNNING. Those callbacks will indeed call blocking ops themselves so this is required.

In some cases the zero-length hw_desc array at the end of ablkcipher_edesc struct requires for 4B of tail padding. Due to tail padding and the way pointers to S/G table and IV are computed: edesc->sec4_sg = (void *)edesc + sizeof(struct ablkcipher_edesc) + desc_bytes; iv = (u8 *)edesc->hw_desc + desc_bytes + sec4_sg_bytes; first 4 bytes of IV are overwritten by S/G table. Update computation of pointer to S/G table to rely on offset of hw_desc member and not on sizeof() operator.

2018-09-13crypto: ccp - add timeout support in the SEV commandBrijesh Singh
Currently, the CCP driver assumes that the SEV command issued to the PSP will always return (i.e. it will never hang). But recently, firmware bugs have shown that a command can hang. Since of the SEV commands are used in probe routines, this can cause boot hangs and/or loss of virtualization capabilities. To protect against firmware bugs, add a timeout in the SEV command execution flow. If a command does not complete within the specified timeout then return -ETIMEOUT and stop the driver from executing any further commands since the state of the SEV firmware is unknown.

This patch fixes sleep-in-atomic bugs in AES-CBC and AES-XTS VMX implementations. The problem is that the blkcipher_* functions should not be called in atomic context.

2018-08-08crypto/nx: Initialize 842 high and normal RxFIFO control registersHaren Myneni
NX increments readOffset by FIFO size in receive FIFO control register when CRB is read. But the index in RxFIFO has to match with the corresponding entry in FIFO maintained by VAS in kernel. Otherwise NX may be processing incorrect CRBs and can cause CRB timeout. VAS FIFO offset is 0 when the receive window is opened during initialization. When the module is reloaded or in kexec boot, readOffset in FIFO control register may not match with VAS entry. This patch adds nx_coproc_init OPAL call to reset readOffset and queued entries in FIFO control register for both high and normal FIFOs.

2018-08-03crypto: ccp - Check for NULL PSP pointer at module unloadTom Lendacky
Should the PSP initialization fail, the PSP data structure will be freed and the value contained in the sp_device struct set to NULL. At module unload, psp_dev_destroy() does not check if the pointer value is NULL and will end up dereferencing a NULL pointer. Add a pointer check of the psp_data field in the sp_device struct in psp_dev_destroy() and return immediately if it is NULL.

2018-08-03crypto: ccree - allow bigger than sector XTS opGilad Ben-Yossef
The ccree driver had a sanity check that we are not asked to encrypt an XTS buffer bigger than a sane sector size since XTS IV needs to include the sector number in the IV so this is not expected in any real use case. Unfortunately, this breaks cryptsetup benchmark test which has a synthetic performance test using 64k buffer of data with the same IV. Remove the sanity check and allow the user to hang themselves and/or run benchmarks if they so wish.

In certain error path req_ctx->iv was being freed despite not being allocated because it was not initialized to NULL. Rather than play whack a mole with the structure various field, zero it before use. This fixes a kernel panic that may occur if an invalid buffer size was requested triggering the bug above.

2018-08-03crypto: hisilicon - SEC security accelerator driverJonathan Cameron
This accelerator is found inside hisilicon hip06 and hip07 SoCs. Each instance provides a number of queues which feed a different number of backend acceleration units. The queues are operating in an out of order mode in the interests of throughput. The silicon does not do tracking of dependencies between multiple 'messages' or update of the IVs as appropriate for training. Hence where relevant we need to do this in software.
