Test added to the unittest plugin / test_vlib.py Type: improvement Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: I73445e57918347c102ff6f5e8c9ddb9bd96f1407

2020-12-14vppinfra: simpler and faster pool_foreachDamjan Marion1-15/+31
- reduces number of instructions generated 4 times compared to old code - adds pool_foreach2 which is more friendly to clang-format Type: improvement Change-Id: I51e9c7fb09655c60d883987dadf5b2666c12b3f7 Signed-off-by: Damjan Marion <damarion@cisco.com>
2020-09-28vppinfra: don't call dlmalloc API directly from the codeDamjan Marion1-1/+0
- it is confusing from end consumer perspective that some thing is somewhere called heap and somewhere mspace - this is base for additional work where heap pointer is not the same thing like mspace Type: improvement Change-Id: I644d5a0de17690d65d164d8cec3c5654571629ef Signed-off-by: Damjan Marion <damarion@cisco.com>

2019-11-27misc: add address sanitizer heap instrumentationBenoît Ganne1-4/+9
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>

2018-11-29vcl: basic support for apps that forkFlorin Coras1-1/+1
- intercept fork and register a new worker with vpp - share sessions between parent and forked child - keep binary api state per worker Change-Id: Ib177517d661724fa042bd2d98d18e777056352a2 Signed-off-by: Florin Coras <fcoras@cisco.com>

Change-Id: I192e340bd072d27bf6ddc382347ad5c3ca411bad Signed-off-by: Florin Coras <fcoras@cisco.com>
2018-10-19Add pool_get_zero, pool_get_aligned_zero macrosDave Barach1-1/+13
Shorthand for the pattern: pool_get (<pool>, ep); memset (ep, 0, sizeof(*ep)); Should have done this years ago. Change-Id: Ideeb27a79ff4ca3e9a077c973b297671d1fa2d26 Signed-off-by: Dave Barach <dave@barachs.net>
2018-09-27Trivial: Cleanup some typos.Paul Vinciguerra1-1/+1
This is a new commit for code under a different maintainer. Change-Id: I79fa403fec6a312238a9a4b18b35dbcafaa05439 Signed-off-by: Paul Vinciguerra <pvinci@vinciconsulting.com>

2018-06-27Tune pool_get / pool_putDave Barach1-6/+8
Stop spending cycles repeatedly tail-trimming the pool free element bitmap; possibly at the expense of slightly hurting pool_foreach peformance. Change-Id: I8a7f3e7b26c71d7496ba9393b2a167dc7f538355 Signed-off-by: Dave Barach <dave@barachs.net>
2018-05-11Periodic scan and probe of IP neighbors to maintain neighbor poolsJohn Lo1-0/+3
Scan IPv4 and IPv6 neigbor pool entries once a minute to keep them up to date. The neighbor of an entry is probed if its time-stamp is older than 1 minute. If the neighbor respond, its time-stamp will be updated. If there is no response from a neighbor, its entry will be deleted when the time-stamp of the entry become more than 4 minutes old. Static neighbor entries are not probed nor deleted. Implemented CLI and API to enable and disable priodic scan of IPv4, IPv6 or both types of IP neighbors. CLI is "ip scan-neighbor" and API is "ip_scan_neighbor_enable_disable". Other IP neighbor scan parameters can also be changed from their defaults via the CLI/API.

2018-05-04Harmonize vec/pool_get_aligned object sizes and alignment requestsDave Barach1-0/+2
Object sizes must evenly divide alignment requests, or vice versa. Otherwise, only the first object will be aligned as requested. Three choices: add CLIB_CACHE_LINE_ALIGN_MARK(align_me) at the end of structures, manually pad to an even divisor or multiple of the alignment request, or use plain vectors/pools. static assert for enforcement.

2017-11-14vppinfra: fix pool_get_aligned_will_expand for fixed poolsFlorin Coras1-3/+4

2017-09-01Add fixed-size, preallocated pool supportDave Barach1-29/+90
Simply call pool_init_fixed(...) before using the pool. Note that fixed, preallocated pools live in individually-mmap'ed address segments, except for the free element bitmap. A large fixed pool can exceed 4gb. Fix tcp buffer allocator leak, remove broken assert Change-Id: I4421082e12a77c41c6e20f7747f3150dcd01fc26 Signed-off-by: Dave Barach <dave@barachs.net>
2017-08-02Fix tcp tx buffer allocationFlorin Coras1-1/+1
- Make tcp output buffer allocation macro an inline function - Use per ip version per thread tx frames for retransmits and timer events - Fix / parameterize tcp data structure preallocation - Add a couple of gdb-callable show commands - Fix local endpoint cleanup Change-Id: I67b47b7570aa14cb4634b6fd93c57cd2eacbfa29 Signed-off-by: Florin Coras <fcoras@cisco.com> Signed-off-by: Dave Barach <dave@barachs.net>
