2020-04-22misc: asan: do not poison memory after munmap()Benoît Ganne1-1/+0
It is a bad idea to poison memory after munmap because the address space can be reused (eg. for global data of dlopen()ed object) and ASan model allows access by default. Moreover, access to a stale address space will fault. Type: fix Change-Id: I356de422f255447d9d50a3a71fb0c2eaa790d731 Signed-off-by: Benoît Ganne <bganne@cisco.com>
2020-04-21vppinfra: bihash improvementsDave Barach1-0/+1
Template instances can allocate BIHASH_KVP_PER_PAGE data records tangent to the bucket, to remove a dependent read / prefetch. Template instances can ask for immediate memory allocation, to avoid several branches in the lookup path. Clean up l2 fib, gpb plugin codes: use clib_bihash_get_bucket(...) Use hugepages for bihash allocation arenas Type: improvement Signed-off-by: Dave Barach <dave@barachs.net> Signed-off-by: Damjan Marion <damarion@cisco.com> Change-Id: I92fc11bc58e48d84e2d61f44580916dd1c56361c
2020-02-11vppinfra: remove the historical mheap memory allocatorDave Barach1-36/+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 Ganne1-21/+22
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: add clib_mem_free_sBenoît Ganne1-0/+8
IPsec zero-es all allocated key memory including memory sur-allocated by the allocator. Move it to its own function in clib mem infra to make it easier to instrument. Type: refactor Change-Id: Icd1c44d18b741e723864abce75ac93e2eff74b61 Signed-off-by: Benoît Ganne <bganne@cisco.com>
2019-08-02vppinfra: Expose function setting __os_thread_indexNathan Skrzypczak1-0/+21
Type: feature This is needed when creating pthreads in client applications, they need a way to set __os_thread_index per thread that does not conflict with the binary API thread index. If __os_thread_index is left to 0 in two client pthreads and they call vl_msg_api_alloc and vec_resize at the same time it can fail due to them sharing (and push/poping) the same clib_per_cpu_mheaps slot.

2019-05-17Add a debug-CLI leak-checkerDave Barach1-0/+2
leak-check { <any-debug-cli-command-and-args> } Hint: "set term history off" or you'll have to sort through a bunch of bogus leaks related to the debug cli history mechanism. Cleaned up a set of reported leaks in the "show interface" command. At some point, we thought about making a per-thread vlib_mains vector, but we never did that. Several interface-related CLI's maintained local static cache vectors. Not a bad idea, but not useful as things shook out. Removed the static vectors.

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.
