Hello,
I don't know what to think of it. It does not make much sense
to me at the moment. If I'm not mistaken kernel crashes
here at line 156:
119 chacha20poly1305_encrypt(
120 uint8_t *dst,
121 const uint8_t *src,
122 const size_t src_len,
123 const uint8_t *ad,
124 const size_t ad_len,
125 const uint64_t nonce,
126 const uint8_t key[CHACHA20POLY1305_KEY_SIZE]
127 ) {
128 poly1305_state poly1305_ctx;
129
chacha_ctx chacha_ctx;
130 union {
131 uint8_t b0[CHACHA20POLY1305_KEY_SIZE];
132 uint64_t lens[2];
133 } b = { { 0 } };
...
152
153 poly1305_finish(&poly1305_ctx, dst + src_len);
154
155 explicit_bzero(&chacha_ctx, sizeof(chacha_ctx));
156 explicit_bzero(&b, sizeof(b));
157 }
explicit_bzero() as a kind of memset() alias. would you be able to
grab the same information plus output of 'show registers' command
in ddb? next time when APU box will crash.
I wonder what makes those two boxes so special that wg makes them
to crash. Can you think of something? this might help every
detail counts.
thanks and
regards
