2020-09-09svm: fix non-null-terminated stringBenoît Ganne1-1/+1
Type: fix Change-Id: Ia9cd71ce12584cd8ef90bfe357cf762dd7653f71 Signed-off-by: Benoît Ganne <bganne@cisco.com>
2020-04-22svm: asan: fix asan supportBenoît Ganne1-0/+10
- restrict the unittests SVM address space to what is supported by ASan - mark SVM mmap()ed address space accessible for ASan - SVM shared memory heap scheme means some allocation can happen outside the current process. Lazily mark those accessible for ASan Type: fix Change-Id: I7c196c80b2a5297651d0afa54f1a8e478fcf59b1 Signed-off-by: Benoît Ganne <bganne@cisco.com>

2020-02-11vppinfra: remove the historical mheap memory allocatorDave Barach1-28/+0
The mheap allocator has been turned off for several releases. This commit removes the cmake config parameter, parallel support for dlmalloc and mheap, and the mheap allocator itself. Type: refactor Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: I104f88a1f06e47e90e5f7fb3e11cd1ca66467903

2019-11-27misc: add address sanitizer heap instrumentationBenoît Ganne1-0/+4
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>
2019-05-01svm: remove dead code triggering overflowBenoît Ganne1-26/+0
split_point is incremented twice per iteration whereas we only check for *split_point != '\0' at the beginning of the iteration. This code seems dead so remove it altogether. Change-Id: Iabaf26cd5c0c8f747e267bcff044540a2376d3f6 Signed-off-by: Benoît Ganne <bganne@cisco.com>

2018-07-18Add config option to use dlmalloc instead of mheapDave Barach1-0/+18
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>
2018-06-05VPP API: Memory traceOle Troan1-0/+4
if you plan to put a hash into shared memory, the key sum and key equal functions MUST be set to constants such as KEY_FUNC_STRING, KEY_FUNC_MEM, etc. -lvppinfra is PIC, which means that the process which set up the hash won't have the same idea where the key sum and key compare functions live in other processes.

2018-05-10vppinfra: use count_trailing_zeros in sparse_vec_indexDamjan Marion1-1/+1
It is much cheaper to use ctzll than to do shift,subtract and mask in likely case when we are looking for 1st set bit in the uword. Change-Id: I31954081571978878c7098bafad0c85a91755fa2 Signed-off-by: Damjan Marion <damarion@cisco.com>
2018-02-02vlmemory/svm: fix client detach from svm regionFlorin Coras1-5/+34
Clients cannot know at svm region detach time if the shm backing files have been recreated (e.g., if vpp restarts) and therefore should not try to unlink them. Otherwise, terminating clients attached to previous instantiations of a re-allocated region end up making the new instance un-mappable by removing its backing file.

2017-10-03Repair vlib API socket serverDave Barach1-91/+102
- Teach vpp_api_test to send/receive API messages over sockets - Add memfd-based shared memory - Add api messages to create memfd-based shared memory segments - vpp_api_test supports both socket and shared memory segment connections - vpp_api_test pivot from socket to shared memory API messaging - add socket client support to libvlibclient.so - dead client reaper sends ping messages, container-friendly - dead client reaper falls back to kill (<pid>, 0) live checking if e.g. a python app goes silent for tens of seconds - handle ping messages in python client support code - teach show api ring about pairwise shared-memory segments - fix ip probing of already resolved destinations (VPP-998) We'll need this work to implement proper host-stack client isolation Change-Id: Ic23b65f75c854d0393d9a2e9d6b122a9551be769 Signed-off-by: Dave Barach <dave@barachs.net> Signed-off-by: Dave Wallace <dwallacelf@gmail.com> Signed-off-by: Florin Coras <fcoras@cisco.com>

2017-08-25jvpp: introducing callback api and future api tests for all plugins (VPP-591)Matej Perina1-1/+1
test can be run with: make test TEST=test_jvpp memory_shared.c: declaring and assigning variable in if statement makes it usage outside statement impossible. Looks like memory space assigned to variable declared in statement is freed when statement ends svm.c: - fixed case when root path can have a "/" at beggining - added option for test to operate over shared memory space with /vpe-api name and not create new one with name consisting of root path and region name which would require root permisions Change-Id: Iff1170dc6a5c1be134c152f2757c7ab9b919a8ed Signed-off-by: Matej Perina <mperina@cisco.com>
2017-08-18API: More gracefully fail when opening shared memory segment fails.Ole Troan1-5/+8
API clients would fail with an ASSERT (and core dump) whenever the API shared memory segment could not be opened. This returns an error value to the client's connect instead. Change-Id: Id122a3a090b24b139c382ae09f341bde61fd2540 Signed-off-by: Ole Troan <ot@cisco.com>
2017-08-14jvpp: make shm_prefix configurable (VPP-591)Jan Srnicek1-1/+2
svm.c - set default map region root path only if root path is not already present memory_shared.c - added option for tests to send memory region name and root path in one variable, if so name and root path are separated here and set to map region structure so find function can find it properly jvpp-registry.c - added parameters shmPrefix to be able pass + removed sudo restriction specific shared memory prefix that is used while starting python tests(see framework.py) JVppRegistyImpl - added option to specify shmPrefix VppJNIConnection - added option to specify shmPrefix Change-Id: I3f89f867fb9b20eef00fbd497cb0e41b25d6eab7 Signed-off-by: Jan Srnicek <jsrnicek@cisco.com> Signed-off-by: Matej Perina <mperina@cisco.com>

- api-segment prefix not used when unlinking shm files - unlink root region on exit if no clients referenced - stale reference to freed segment name - don't add fake client to /db unless CLIB_DEBUG > 2 - turn off the gmond plugin - clean up unused vars in vpp/api Change-Id: I66451fcfd6ee64a12466c2d6c209050e3cdb74b7 Signed-off-by: Dave Wallace <dwallacelf@gmail.com> Signed-off-by: Dave Barach <dave@barachs.net>
