2021-01-20svm: add standard include for __WORDSIZENathan Moos1-0/+1
Type: fix In glibc, the __WORDSIZE macro is defined in a header included indirectly from svm_common.h. In musl, the __WORDSIZE macro is not indirectly included, so this patch directly includes <sys/user.h> to ensure the __WORDSIZE macro is available.

2020-11-19svm: fix high segment base address for ASanBenoît Ganne1-1/+1
AddressSanitizer has specific requirements on memory map. In particular, the range [0x00007fff8000, 0x10007fff7fff] is reserved for ASan use. Type: fix Fixes: f260eb97866978746ebd3f3441dc66e4ff7111cd Change-Id: Ie96c4dd88b4f02d7fc5c24464572ff72cb6fd96b Signed-off-by: Benoît Ganne <bganne@cisco.com>
2020-11-13svm: change high_seg_basevaNathan Skrzypczak1-2/+2
Type: fix It appears that the session layer baseva is conflicting with DPDK. 0x2000000000 seem to be working experimentally Configurable with : session { segment-baseva 0x2000000000 } Change-Id: Ie93b9b9eb56a796877d614f78eb5801ea8e5ab31 Signed-off-by: Nathan Skrzypczak <nathan.skrzypczak@gmail.com>
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>

2018-02-02vlmemory/svm: fix client detach from svm regionFlorin Coras1-0/+2
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.

2017-11-10Map SVM regions at a sane offset on arm64Brian Brooks1-1/+7
Mapping shared virtual memory at 0x30000000, which appears to be derived from x86-32, turns out to be too close to the heap on arm64 systems. The symptoms of memory corruption were random and included crashes in the Python runtime and what appeared to be corruption of malloc's internal mutex. Thanks to Gabriel Ganne for pointing out that disabling ASLR seemed to mitigate the situation. This patch maps SVM regions at an offset from the arm64 kernel constant TASK_UNMAPPED_BASE and also assumes a 48-bit VA (for Ubuntu).

2017-10-03Repair vlib API socket serverDave Barach1-0/+2
- 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>

2017-08-18API: More gracefully fail when opening shared memory segment fails.Ole Troan1-1/+1
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>
2017-07-01Refactor API message handling codeKlement Sekera1-0/+133
This is preparation for new C API. Moving common stuff to separate headers reduces dependency issues. Change-Id: Ie7adb23398de72448e5eba6c1c1da4e1bc678725 Signed-off-by: Klement Sekera <ksekera@cisco.com>
