Change subject: [util] Changes to allow serializing/de-serializing BlockBloomFilter to a custom format ...................................................................... Patch Set 1: (1 comment) http://gerrit.cloudera.org:8080/#/c/15396/1/src/kudu/util/block_bloom_filter.cc File src/kudu/util/block_bloom_filter.cc: http://gerrit.cloudera.org:8080/#/c/15396/1/src/kudu/util/block_bloom_filter.cc@134 PS1, Line 134: directory_ > It's possible the input directory size is 0 if alway_false is TRUE. Should If always_false is true doesn't mean directory size is 0 even with 0 log_space_bytes. For the case when always_false is true, it'd be a directory that's empty but with valid memory allocated just no elements inserted in the BF. Based on the implementation of InitInternal(), directory_size() can't be 0. So if input directory.size() is 0 then check above on L129 will catch it. Now if Slice were to wrap a nullptr and specify a non-zero size for "directory" they we have a problem with memcpy(). That appears like a artificially crafted rogue Slice to me. -- To view, visit http://gerrit.cloudera.org:8080/15396 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: kudu Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: I79504813024abaf452e2c2b244391024b442d6f7 Gerrit-Change-Number: 15396 Gerrit-PatchSet: 1 Gerrit-Owner: Bankim Bhavsar <[email protected]> Gerrit-Reviewer: Adar Dembo <[email protected]> Gerrit-Reviewer: Bankim Bhavsar <[email protected]> Gerrit-Reviewer: Kudu Jenkins (120) Gerrit-Reviewer: Thomas Tauber-Marshall <[email protected]> Gerrit-Reviewer: Wenzhe Zhou <[email protected]> Gerrit-Comment-Date: Tue, 10 Mar 2020 23:50:25 +0000 Gerrit-HasComments: Yes
