Package: mariadb-plugin-rocksdb Version: 1:10.3.27-0+deb10u1 Severity: important
Dear Maintainer, After updating from 10.3.23 to either 10.3.25 (from security) or 10.3.27, the package crashes on startup with SIGILL on a Raspberry Pi 4. Running the package under gdb shows the following backtrace: #0 0x0000007ff467afe4 in crc32c_arm64(unsigned int, unsigned char const*, unsigned int) () from /usr/lib/aarch64-linux-gnu/mariadb19/plugin/ha_rocksdb.so #1 0x0000007ff44fd15c in rocksdb::log::Reader::ReadPhysicalRecord(rocksdb::Slice*, unsigned long*) () from /usr/lib/aarch64-linux-gnu/mariadb19/plugin/ha_rocksdb.so #2 0x0000007ff44fd2f4 in rocksdb::log::Reader::ReadRecord(rocksdb::Slice*, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >*, rocksdb::WALRecoveryMode) () from /usr/lib/aarch64-linux-gnu/mariadb19/plugin/ha_rocksdb.so #3 0x0000007ff4545cdc in rocksdb::VersionSet::ListColumnFamilies(std::vector<std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::allocator<std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > > >*, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, rocksdb::FileSystem*) () from /usr/lib/aarch64-linux-gnu/mariadb19/plugin/ha_rocksdb.so #4 0x0000007ff4460844 in rocksdb::DB::ListColumnFamilies(rocksdb::DBOptions const&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::vector<std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >, std::allocator<std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > > >*) () from /usr/lib/aarch64-linux-gnu/mariadb19/plugin/ha_rocksdb.so #5 0x0000007ff44067bc in ??

Downgrading to 10.3.23 fixes the problem. I haven't been able to reproduce the problem on a clean install inside a VM - maybe it depends on having some data in the database? -- System Information: Debian Release: 10.7 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: arm64 (aarch64) Foreign Architectures: armhf Kernel: Linux 5.4.72-v8+ (SMP w/4 CPU cores; PREEMPT) Kernel taint flags: TAINT_CRAP Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) (ignored: LC_ALL set to en_US.UTF-8), LANGUAGE=en_US.UTF-8 (charmap=UTF-8) (ignored: LC_ALL set to en_US.UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages mariadb-plugin-rocksdb depends on: ii libc6 2.28-10 ii liblz4-1 1.8.3-1 ii libsnappy1v5 1.1.7-1 ii libstdc++6 8.3.0-6 ii libzstd1 1.3.8+dfsg-3 ii mariadb-server-10.3 1:10.3.27-0+deb10u1 ii rocksdb-tools 5.17.2-3 ii zlib1g 1:1.2.11.dfsg-1 Versions of packages mariadb-plugin-rocksdb recommends: ii python-mysqldb 1.3.10-2 mariadb-plugin-rocksdb suggests no packages. -- Configuration Files: /etc/mysql/mariadb.conf.d/rocksdb.cnf changed: [mariadb] plugin-load-add=ha_rocksdb.so rocksdb_unsafe_for_binlog=1 rocksdb_block_cache_size=128M rocksdb_block_size=128k rocksdb_large_prefix=1 rocksdb_db_write_buffer_size=128M rocksdb-override-cf-options='default={bottommost_compression=kZSTD;bottommost_compression_opts=-14:19:0:0:0:true;target_file_size_base=16m;max_bytes_for_level_base=64m;target_file_size_multiplier=2;}' rocksdb_max_open_files=-1 rocksdb_max_log_file_size=16M rocksdb_keep_log_file_num=4 rocksdb_wal_recovery_mode=2 gtid_pos_auto_engines = 'InnoDB,RocksDB' -- no debconf information
