This change sets a low limit for multibulk and bulk length in the protocol for unauthenticated connections, so that they can't easily cause redis to allocate massive amounts of memory by sending just a few characters on the network. The new limits are 10 arguments of 16kb each (instead of 1m of 512mb) (cherry picked from commit 3d221e81f3b680543e34942579af190b049ff283)

On 32 bit platform, the bit position of GETBIT/SETBIT/BITFIELD/BITCOUNT,BITPOS may overflow (see CVE-2021-32761) (#9191) GETBIT, SETBIT may access wrong address because of wrap. BITCOUNT and BITPOS may return wrapped results. BITFIELD may access the wrong address but also allocate insufficient memory and segfault (see CVE-2021-32761). This commit uses `uint64_t` or `long long` instead of `size_t`. related https://github.com/redis/redis/pull/8096 At 32bit platform: > setbit bit 4294967295 1 (integer) 0 > config set proto-max-bulk-len 536870913 OK > append bit "\xFF" (integer) 536870913 > getbit bit 4294967296 (integer) 0 When the bit index is larger than 4294967295, size_t can't hold bit index. In the past, `proto-max-bulk-len` is limit to 536870912, so there is no problem. After this commit, bit position is stored in `uint64_t` or `long long`. So when `proto-max-bulk-len > 536870912`, 32bit platforms can still be correct. For 64bit platform, this problem still exists. The major reason is bit pos 8 times of byte pos. When proto-max-bulk-len is very larger, bit pos may overflow. But at 64bit platform, we don't have so long string. So this bug may never happen. Additionally this commit add a test cost `512MB` memory which is tag as `large-memory`. Make freebsd ci and valgrind ci ignore this test. * This test is disabled in this version since bitops doesn't rely on proto-max-bulk-len. some of the overflows can still occur so we do want the fixes. (cherry picked from commit 71d45287) (cherry picked from commit 2be8f1de1d452886fbf45030409707c52323da20)

Similarly to EXPIREAT with TTL in the past, which implicitly deletes the key and return success, RESTORE should not store key that are already expired into the db. When used together with REPLACE it should emit a DEL to keyspace notification and replication stream. (cherry picked from commit 5977a948) (cherry picked from commit 95ba01b5)

This commit solves the following bug: 127.0.0.1:6379> XGROUP CREATE x grp $ MKSTREAM OK 127.0.0.1:6379> XADD x 666 f v "666-0" 127.0.0.1:6379> XREADGROUP GROUP grp Alice BLOCK 0 STREAMS x > 1) 1) "x" 2) 1) 1) "666-0" 2) 1) "f" 2) "v" 127.0.0.1:6379> XADD x 667 f v "667-0" 127.0.0.1:6379> XDEL x 667 (integer) 1 127.0.0.1:6379> XREADGROUP GROUP grp Alice BLOCK 0 STREAMS x > 1) 1) "x" 2) (empty array) The root cause is that we use s->last_id in streamCompareID while we should use the last *valid* ID

This commit solves several edge cases that are related to exhausting the streamID limits: We should correctly calculate the succeeding streamID instead of blindly incrementing 'seq' This affects both XREAD and XADD. Other (unrelated) changes: Reply with a better error message when trying to add an entry to a stream that has exhausted last_id

Calling XADD with 0-0 or 0 would result in creating an empty key and storing it in the database. Even worse, because XADD will reply with error the action will not be replicated, creating a master-replica inconsistency

In fast systems "SLOWLOG RESET" is fast enough to don't be logged even when the time limit is "1" sometimes. Leading to false positives such as: [err]: SLOWLOG - can be disabled in tests/unit/slowlog.tcl Expected '1' to be equal to '0'

solving few replication related tests race conditions which fail on slow machines bugfix in slave buffers test: since the test is executed twice, each time with a different commands count, the threshold for the delta can't be a constant.

The XCLAIM docs state the XCLAIM increments the delivery counter for messages. This PR makes the code match the documentation - which seems like the desired behaviour - whilst still allowing RETRYCOUNT to be specified manually. My understanding of the way streamPropagateXCLAIM() works is that this change will safely propagate to replicas since retry count is pulled directly from the streamNACK struct. Fixes #5194

Few tests had borderline thresholds that were adjusted. The slave buffers test had two issues, preventing the slave buffer from growing: 1) the slave didn't necessarily go to sleep on time, or woke up too early, now using SIGSTOP to make sure it goes to sleep exactly when we want. 2) the master disconnected the slave on timeout

it looks like on slow machines we're getting: [err]: slave buffer are counted correctly in tests/unit/maxmemory.tcl Expected condition '$slave_buf > 2*1024*1024' to be true (16914 > 2*1024*1024) this is a result of the slave waking up too early and eating the slave buffer before the traffic and the test ends.

on slower machines, the active defrag test tended to fail. although the fragmentation ratio was below the treshold, the defragger was still in the middle of a scan cycle. this commit changes: - the defragger uses the current fragmentation state, rather than the cache one that is updated by server cron every 100ms. this actually fixes a bug of starting one excess scan cycle - the test lets the defragger use more CPU cycles, in hope that the defrag will be faster, but also give it more time before we give up.
