Bug ID: 1861
Summary: rte_memcpy references past end of source
Product: DPDK
Version: 25.11
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: minor
Priority: Normal
Component: core
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
When fips_validation example is compiled with Gcc-16 it generates an array out
of bounds warning inside rte_memcpy(). It looks like this because copy source
is a 15 byte array and rte_memcpy is using vector instruction that references
past that.
In function ‘get_hash_oid’,
inlined from ‘prepare_rsa_xform’ at
../examples/fips_validation/main.c:1607:12:
../examples/fips_validation/main.c:890:20: warning: array subscript
‘__m128i_u[0]’ is partly outside array bounds of ‘uint8_t[15]’ {aka ‘unsigned
char[15]’} [-Warray-bounds=]
890 | id = id_sha1;
| ~~~^~~~~~~~~
../examples/fips_validation/main.c: In function ‘prepare_rsa_xform’:
../examples/fips_validation/main.c:882:17: note: object ‘id_sha1’ of size 15
882 | uint8_t id_sha1[] = {0x30, 0x21, 0x30, 0x09, 0x06, 0x05,
Workaround is to just use memcpy() which handles this case correctly.
