2018-11-26vppinfra: prevent dlmalloc from allocating memory via mmap_alloc()Andrew Yourtchenko1-1/+22
If the heap does not have enough space to satisfy allocation request, the allocator calls sys_alloc(). There, if the request is bigger than mparams.mmap_threshold, the mmap_alloc() is called to allocate memory via a direct mmap call. The resulting allocated memory is properly recognized by clib_mem_is_heap_object() only for the first such request. Subsequent requests overwrite the tracking data, resulting in previously "valid" addresses become invalid, as seen by clib_mem_is_heap_object(). The result is a misleading behavior which masks other issues. This is a temporary change to avoid the affected codepath until there is a proper fix to track the directly mmap-allocated memory.

2018-08-24Rename struct mallinfo -> struct dlmallinfoDave Barach1-5/+5
Also: don't #include /usr/include/malloc.h in dlmalloc.h Change-Id: Ic73ff8862cc8aba371488b912255e28dd96374ff Signed-off-by: Dave Barach <dave@barachs.net>
2018-07-27dlmalloc: use static magic constant for debug imagesFlorin Coras1-0/+1
Avoids crashes on restarts if svm root region backing file was not cleaned up. Change-Id: I608cf5711aa8c3f9620900473bdf76bde8b918de Signed-off-by: Florin Coras <fcoras@cisco.com>
2018-07-27-DCLIB_DEBUG => turn on extra checks in dlmallocDave Barach1-2/+11
Also: call os_panic() on a heap botch crash, attempt to generate a post-mortem API dump, etc. Add an "ugly" test case to vec_test.c, to cause a configurable block overrun. Change-Id: I7b29a7645277f9e485e06ff83335306fedc24b71 Signed-off-by: Dave Barach <dave@barachs.net>
2018-07-18Add config option to use dlmalloc instead of mheapDave Barach1-0/+1450
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>
