I used aes-cbc as a template for ofb. But sadly I forgot to update set_key method to crypto4xx_setkey_aes_ofb(). this was caught by the testmgr: alg: skcipher: Test 1 failed (invalid result) on encr. for ofb-aes-ppc4xx 00000000: 76 49 ab ac 81 19 b2 46 ce e9 8e 9b 12 e9 19 7d 00000010: 50 86 cb 9b 50 72 19 ee 95 db 11 3a 91 76 78 b2 00000020: 73 be d6 b8 e3 c1 74 3b 71 16 e6 9e 22 22 95 16 00000030: 3f f1 ca a1 68 1f ac 09 12 0e ca 30 75 86 e1 a7 With the correct set_key method, the aes-ofb cipher passes the test. name : ofb(aes) driver : ofb-aes-ppc4xx module : crypto4xx priority : 300 refcnt : 1 selftest : passed internal : no type : ablkcipher async : yes blocksize : 16 min keysize : 16 max keysize : 32 ivsize : 16 geniv : <default> Signed-off-by:

The hmac_mc parameter of set_dynamic_sa_command_1() was defined but not used. On closer inspection it turns out, it was never wired up. Signed-off-by:

The code is simplified by using two __be64 values for the operation instead of using two arrays of u8. This allows to get rid of the memory alignment code. In addition, the crypto_xor can be replaced with a native XOR operation. Finally, the definition of the variables is re-arranged such that the data structures come before simple variables to potentially reduce memory space. Signed-off-by:

If the algorithm we're parallelizing is asynchronous we might change CPUs between padata_do_parallel() and padata_do_serial(). However, we don't expect this to happen as we need to enqueue the padata object into the per-cpu reorder queue we took it from, i.e. the same-cpu's parallel queue. Ensure we're not switching CPUs for a given padata object by tracking the CPU within the padata object. If the serial callback gets called on the wrong CPU, defer invoking padata_reorder() via a kernel worker on the CPU we're expected to run on. Signed-off-by:

The reorder timer function runs on the CPU where the timer interrupt was handled which is not necessarily one of the CPUs of the 'pcpu' CPU mask set. Ensure the padata_reorder() callback runs on the correct CPU, which is one in the 'pcpu' CPU mask set and, preferrably, the next expected one. Do so by comparing the current CPU with the expected target CPU. If they match, call padata_reorder() right away. If they differ, schedule a work item on the target CPU that does the padata_reorder() call for us. Signed-off-by:

Mathias Krause authored
The parallel queue per-cpu data structure gets initialized only for CPUs in the 'pcpu' CPU mask set. This is not sufficient as the reorder timer may run on a different CPU and might wrongly decide it's the target CPU for the next reorder item as per-cpu memory gets memset(0) and we might be waiting for the first CPU in cpumask.pcpu, i.e. cpu_index 0. Make the '__this_cpu_read(pd->pqueue->cpu_index) == next_queue->cpu_index' compare in padata_get_next() fail in this case by initializing the cpu_index member of all per-cpu parallel queues. Use -1 for unused ones. Signed-off-by:

In 32-bit mode, the x86 architecture can hold full 32-bit pointers. Therefore, the code that copies the current address to the %ecx register and uses %ecx-relative addressing is useless, we could just use absolute addressing. The processors have a stack of return addresses for branch prediction. If we use a call instruction and pop the return address, it desynchronizes the return stack and causes branch prediction misses. This patch also moves the data to the .rodata section. Signed-off-by:

This patch refactors and moves the dynamic_contents helper functions into the crypto4xx_sa.h header file. * get_dynamic_sa_iv_size is no longer needed, as the cryptoapi provides the required IV size information as well. * refactor the function declarations to use the a pointer to the dynamic_sa_contents union, instead of the crypto4xx_ctx. * rename get_dynamic_sa_offset_key_field to get_dynamic_sa_key_field. It returns the pointer to the key directly. Signed-off-by:
