2022-03-31vppinfra: vectors with non-default heapDamjan Marion1-1/+3
Type: improvement Change-Id: Ic675ad4edbf27b7230fc2a77f00c90c46d6350c3 Signed-off-by: Damjan Marion <damarion@cisco.com>
2022-03-30vppinfra: vector allocator reworkDamjan Marion1-22/+30
- 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>

2022-03-18vppinfra: use stored vec header size to find headerDamjan Marion1-24/+4

2022-03-17vppinfra: vec_max_len, vec_mem_size use stored header sizeDamjan Marion1-27/+34

2022-03-17vppinfra: store vector header size and alignment into headerDamjan Marion1-3/+6
On the forst vector alloc values are stored into header. Later, when vector grows values from header are used istead of provided ones. In the debug image code will assert if same values are not provided. Type: improvement Change-Id: I8fdcfa495e9c1df0f6392c90f634e8c74b73b328 Signed-off-by: Damjan Marion <damarion@cisco.com>
2022-03-14vppinfra: fix vec capacityFlorin Coras1-11/+25
Rename vec_capacity to vec_mem_size as it returned the size of the underlying memory allocation not the number of bytes that can be used for vector elements. Add new vec_max_elts macro that returns number of elements that can fit into generic vector.

2022-01-09vppinfra: Check for NULL vec before the backwards iterationNeale Ranns1-4/+6
Type: improvement 'vec_end(v) - 1' does not yield a good starting point. Check for NULL vec before the loop, so the user does not have to. Signed-off-by: Neale Ranns <neale@graphiant.com> Change-Id: Ia174ec8095bc476853cce709a7048d7a3e3b377d

2020-08-19vppinfra: minor tweaks for cgo interoperationDave Barach1-0/+1
'type' is a keyword in golang, so s/type/event_type/ in elog.h and elsewhere. Add vec_len_not_inline(...), elog_write_file_not_inline(...) and elog_read_file_not_inline(...) since the inline forms aren't usable. More such tweaks may follow.

2019-11-27misc: add address sanitizer heap instrumentationBenoît Ganne1-0/+1
Introduce AddressSanitizer support: https://github.com/google/sanitizers/ This starts with heap instrumentation. vlib_buffer, bihash and stack instrumentation should follow. Type: feature Change-Id: I7f20e235b2f79db72efd0e756f22c75f717a9884 Signed-off-by: Benoît Ganne <bganne@cisco.com>
2019-10-22vppinfra: make coverity happy with vec_set_lenBenoît Ganne1-1/+6
Coverity gets confused by ASSERT((l) <= vec_max_len(v)) when l is 0. Type: fix Change-Id: I247d7015b148233d8f195bcf41e9a047b7a21309 Signed-off-by: Benoît Ganne <bganne@cisco.com>
2019-10-22vppinfra: add vec_set_len()Benoît Ganne1-6/+13
l2-flood and bier nodes reset vector length without updating it to its effective size. Introduce a helper to do it (this allows ASAN to keep track of the new vector size). Type: refactor Change-Id: I2d652550c440f0553a2b49c3ee3d37b49ebc16c3 Signed-off-by: Benoît Ganne <bganne@cisco.com>

2018-07-18Add config option to use dlmalloc instead of mheapDave Barach1-0/+1
Configure w/ --enable-dlmalloc, see .../build-data/platforms/vpp.mk src/vppinfra/dlmalloc.[ch] are slightly modified versions of the well-known Doug Lea malloc. Main advantage: dlmalloc mspaces have no inherent size limit. Change-Id: I19b3f43f3c65bcfb82c1a265a97922d01912446e Signed-off-by: Dave Barach <dave@barachs.net>
