Kernel 6 and gcc 12

Hi Folks,

The build process looks for specific macros that are not in the latest Linux. Where do you define IMB_KEY_SIZE_BYTES

Because it looks like an unknown symbol.

gcm_ctr_vectors_test.h:47:9: error: unknown type name ‘IMB_KEY_SIZE_BYTES’

struct gcm_ctr_vector {
    const uint8_t *K;       /* AES Key */
    IMB_KEY_SIZE_BYTES Klen;/* length of key in bits */.
    const uint8_t *IV;      /* initial value used by GCM */
    uint64_t IVlen;         /* length of IV in bytes */
    const uint8_t *A;       /* additional authenticated data */
    uint64_t Alen;          /* length of AAD in bytes */
    const uint8_t *P;       /* Plain text */
    uint64_t Plen;          /* length of our plaintext */
    /* outputs of encryption */
    const uint8_t *C;       /* same length as PT */
    const uint8_t *T;       /* Authentication tag */
    uint8_t Tlen;           /* AT length can be 0 to 128bits */
};

Hey, what commands were executed that resulted in these errors? Was library installed on the system before compiling the test applications? These are not linux macros but data types and macros coming from intel-ipsec-mb.h header file

[tkanteck]

Hey @spyroot, could you please provide more details here?

[spyroot]

Folks I’m closing it looks like kernel 6 has some odd issue, install command that part of make install , somehow create empty header file. .I.e if you do make install intel-mb copies to /use/include and it empty. ..

OK. Thanks for checking and getting back
