2017-11-03silence clib_mem_unaligned() invalid read found by address-sanitizerGabriel Ganne1-19/+28
clib_mem_unaligned + zap64 casts its input as u64, computes a mask according to the input length, and returns the casted maked value. Therefore all the 8 Bytes of the u64 are systematically read, and the invalid ones are discarded. Since they are discarded correctly, this invalid read can safely be ignored. Revert "fix clib_mem_unaligned() invalid read" This reverts commit 0ed3d81a5fa274283ae69b69a405c385189897d3.

2017-11-01fix clib_mem_unaligned() invalid readGabriel Ganne1-17/+18
clib_mem_unaligned + zap64 casts its input as u64, computes a mask according to the input length, and returns the casted maked value. Therefore all the 8 Bytes of the u64 are systematically read, and the invalid ones are discarded. For example, for a 5-Bytes string, we will do an invalid read of size 3, even though those 3 Bytes are never used. This patch proposes to only read what we have at the cost of reading as a u64 in one call, but that way, we do not trigger an invalid read error.

2017-10-30Add the bihash_vec8_8 variantDave Barach2-0/+425
This is an all-purpose octet-vector memory hash, intended as a thread-safe replacement for hash_create_mem / hash_create_string. All u8 * key vectors are memorized by the hash table. Change-Id: I22944daea8fda07dde8ba118a6529a6d382491f9 Signed-off-by: Dave Barach <dave@barachs.net>

2017-07-19Add a bihash prefetchable bucket-level cacheDave Barach7-37/+320
According to Maciek, the easiest way to leverage the csit "performance trend" job is to actually merge the patch once verified. Manual testing indicates that the patch improves l2 path performance. Other use-cases are TBD. It's possible that we'll need to back out the patch depending on what happens.
