openSUSE-SU-2021:0682-1

This update for redis fixes the following issues:

redis 6.0.13

• CVE-2021-29477: Integer overflow in STRALGO LCS command (boo#1185729)
• CVE-2021-29478: Integer overflow in COPY command for large intsets (boo#1185730)
• Cluster: Skip unnecessary check which may prevent failure detection
• Fix performance regression in BRPOP on Redis 6.0
• Fix edge-case when a module client is unblocked

redis 6.0.12:

• Fix compilation error on non-glibc systems if jemalloc is not used

redis 6.0.11:

• CVE-2021-21309: Avoid 32-bit overflows when proto-max-bulk-len is set high (boo#1182657)
• Fix handling of threaded IO and CLIENT PAUSE (failover), could lead to data loss or a crash
• Fix the selection of a random element from large hash tables
• Fix broken protocol in client tracking tracking-redir-broken message
• XINFO able to access expired keys on a replica
• Fix broken protocol in redis-benchmark when used with -a or --dbnum
• Avoid assertions (on older kernels) when testing arm64 CoW bug
• CONFIG REWRITE should honor umask settings
• Fix firstkey,lastkey,step in COMMAND command for some commands
• RM_ZsetRem: Delete key if empty, the bug could leave empty zset keys

redis 6.0.10:

Command behavior changes:

• SWAPDB invalidates WATCHed keys (#8239)
• SORT command behaves differently when used on a writable replica (#8283)
• EXISTS should not alter LRU (#8016) In Redis 5.0 and 6.0 it would have touched the LRU/LFU of the key.
• OBJECT should not reveal logically expired keys (#8016) Will now behave the same TYPE or any other non-DEBUG command.
• GEORADIUS[BYMEMBER] can fail with -OOM if Redis is over the memory limit (#8107)

Other behavior changes:

• Sentinel: Fix missing updates to the config file after SENTINEL SET command (#8229)
• CONFIG REWRITE is atomic and safer, but requires write access to the config file's folder (#7824, #8051) This change was already present in 6.0.9, but was missing from the release notes.

Bug fixes with compatibility implications (bugs introduced in Redis 6.0):

• Fix RDB CRC64 checksum on big-endian systems (#8270) If you're using big-endian please consider the compatibility implications with RESTORE, replication and persistence.
• Fix wrong order of key/value in Lua's map response (#8266) If your scripts use redis.setresp() or return a map (new in Redis 6.0), please consider the implications.

Bug fixes:

• Fix an issue where a forked process deletes the parent's pidfile (#8231)
• Fix crashes when enabling io-threads-do-reads (#8230)
• Fix a crash in redis-cli after executing cluster backup (#8267)
• Handle output buffer limits for module blocked clients (#8141) Could result in a module sending reply to a blocked client to go beyond the limit.
• Fix setproctitle related crashes. (#8150, #8088) Caused various crashes on startup, mainly on Apple M1 chips or under instrumentation.
• Backup/restore cluster mode keys to slots map for repl-diskless-load=swapdb (#8108) In cluster mode with repl-diskless-load, when loading failed, slot map wouldn't have been restored.
• Fix oom-score-adj-values range, and bug when used in config file (#8046) Enabling setting this in the config file in a line after enabling it, would have been buggy.
• Reset average ttl when empty databases (#8106) Just causing misleading metric in INFO
• Disable rehash when Redis has child process (#8007) This could have caused excessive CoW during BGSAVE, replication or AOFRW.
• Further improved ACL algorithm for picking categories (#7966) Output of ACL GETUSER is now more similar to the one provided by ACL SETUSER.
• Fix bug with module GIL being released prematurely (#8061) Could in theory (and rarely) cause multi-threaded modules to corrupt memory.
• Reduce effect of client tracking causing feedback loop in key eviction (#8100)
• Fix cluster access to unaligned memory (SIGBUS on old ARM) (#7958)
• Fix saving of strings larger than 2GB into RDB files (#8306)

Additional improvements:

• Avoid wasteful transient memory allocation in certain cases (#8286, #5954)

Platform / toolchain support related improvements:

• Fix crash log registers output on ARM. (#8020)
• Add a check for an ARM64 Linux kernel bug (#8224) Due to the potential severity of this issue, Redis will print log warning on startup.
• Raspberry build fix. (#8095)

New configuration options:

• oom-score-adj-values config can now take absolute values (besides relative ones) (#8046)

Module related fixes:

• Moved RMAPIFUNCSUPPORTED so that it's usable (#8037)
• Improve timer accuracy (#7987)
• Allow '\0' inside of result of RM_CreateStringPrintf (#6260)
