2022-04-05vppinfra: refactor address sanitizerDamjan Marion1-31/+30
Type: refactor Change-Id: I5ca142ec1557d5b5c3806b43553ad9d3b5ea1112 Signed-off-by: Damjan Marion <damarion@cisco.com>
2022-03-30vppinfra: vector allocator reworkDamjan Marion1-5/+7
- support of in-place growth of vectors (if there is available space next to existing alloc) - drops the need for alloc_aligned_at_offset from memory allocator, which allows easier swap to different memory allocator and reduces malloc overhead - rework of pool and vec macros to inline functions to improve debuggability - fix alignment - in many cases macros were not using native alignment of the particular datatype. Explicitly setting alignment with XXX_aligned() versions of the macro is not needed anymore in > 99% of cases - fix ASAN usage - avoid use of vector of voids, this was root cause of several bugs found in vec_* and pool_* function where sizeof() was used on voids instead of real vector data type - introduce minimal alignment which is currently 8 bytes, vectors will be always aligned at least to that value (underlay allocator actually always provide 16-byte aligned allocs) Type: improvement Change-Id: I20f4b081bb13bbf7bc0ace85cc4e301787f12fdf Signed-off-by: Damjan Marion <damarion@cisco.com>
2020-11-05vppinfra: mspace_get_aligned should respect MALLOC_ALIGNMENTDamjan Marion1-22/+1
While underlying mspace_malloc() respects MALLOC_ALIGNMENT (16) mspace_get_aligned moves start of data for 4 bytes making final result not aligned to MALLOC_ALIGNED. Type: fix Change-Id: Ib1584f315e3658b3b748ebf4886fb7389ce640fe Signed-off-by: Damjan Marion <damarion@cisco.com>
