2019-04-02vppinfra: fix sparse_vec_index() returning non-zero index for some ↵Andrew Yourtchenko1-0/+4
nonexistent elements If we are testing for an index whose membership bitmask happens to sit in LSB of uword, and there is nothing else set in that uword in the member bitmask, the shortcut path returning the valid index is taken even if the element with a given index doesn't exist in the sparse vector. This happens because the count of leading zeroes on the value of 0 is zero, which is equal to the value taken modulo bitsize uword. Take care of that case. Also add unittests showing the problem and verifying that sparse_vec_index2 does not have the same issue.

2019-03-12Use AVX2 as default even on AVX512 systemsDamjan Marion1-1/+1
Use of scalar AVX512 instructions impacts the maximum CPU frequency as they require CPU to request level 1 power license. So sparse use of AVX512 like we do, typically causes more harm than improvement. This patch makes AVX2 higher priority than AVX512, but still there is option to change it on per-node basis: vpp# set node function ethernet-input avx512 Change-Id: I42e03510a6efc1756e22fbb70e8c76d7f74f59d7 Signed-off-by: Damjan Marion <damarion@cisco.com>

2019-01-01Default huge page size to the regular page sizeDave Barach1-0/+6
With this simple tweak, vpp is OK for "make test" or non-dpdk driver operation over a kernel which doesn't support hugepages at all. Tested on a Raspberry-pi 3B+ running the Ubuntu 18.04 64-bit server beta image. It's amazing that such a minimal system will not only self-compile vpp, but also run the unit tests. It's slow, but what do you expect for that amount of money? Change-Id: I7f080f871c828cc4b44be13809495278fadbd717 Signed-off-by: Dave Barach <dave@barachs.net>

2018-12-05Improve strncpy_s src/dst overlap checkDave Barach1-2/+12
Let m = user estimate of the (max) src string length, low = smaller address of (src, dst), hi = larger address (src, dst). if (low + (m - 1) >= hi), we have a *potential* overlapping copy which is not allowed. Before we declare overlap - and return an error - retry the check with m = actual src string length. The resulting "test string" failure affected aarch64 (only) because of differences in test code stack variable placement / alignment.

2018-12-02vppinfra: c11 safe string functionsSteven2-0/+1082
Add memcmp_s, strcmp_s, strncmp_s, strcpy_s, strncpy_s, strcat_s, strncat_s, strtok_s, strnlen_s, and strstr_s C11 safe string API. For migrating extant unsafe API, add also the corresponding macro version of each safe API, clib_memcmp, clib_strcmp, etc. In general, the benefits of the safe string APIs are to provide null pointer checks, add additional argument to specify the string length of the passed string rather than relying on the null terminated character, and src/dest overlap checking for the the string copy operations. The macro version of the API takes the same number of arguments as the unsafe API to provide easy migration. However, it does not usually provide the full aformentioned benefits. In some cases, it is necessary to move to the safe API rather than using the macro in order to avoid some unpredictable problems such as accessing memory beyond what it is intended due to the lack of the passed string length. dbarach: add a "make test" vector, and a doxygen file header cookie.

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.
