There is a -Wimplicit-function-declaration warning in here:
```

The docs state that there is a new and an old argument format.
The current state of the arguments allows mixing the old and new format,
thus the need for two additional oneof blocks.
One for differentiating the new from the old format and then one to
allow setting multiple filters using the new format.
|
| |
|
|
|
| |
--stop: Blocks once the first test fails.
--loop: Execute the specified set of tests forever.
It is useful when we debug some test failures.

plain (#11050)
Before this change, if the module has an embedded string, then uses RedisModule_SaveString
and RedisModule_LoadString, the result would be a raw string instead of an embedded string.
Now the `RDB_LOAD_ENC` flag to `moduleLoadString` only affects integer encoding, but not
embedded strings (which still hold an sds in the robj ptr, so they're actually still raw strings for
anyone who reads them).

In clusterMsgPingExtForgottenNode, sizeof(name) is CLUSTER_NAMELEN,
and sizeof(clusterMsgPingExtForgottenNode) is > CLUSTER_NAMELEN.
Doing a (name + sizeof(clusterMsgPingExtForgottenNode)) sanitizer
generates an out-of-bounds error which is a false positive in here

The kill above is sometimes successful and sometimes already too late.
The PING in pysnc wrong offset test got rejected by bgsaveerr because
lastbgsave_status is C_ERR.
In theory, using diskless can avoid PING being affected, because when
the replica is dropped, we will kill the child with SIGUSR1, and this
will not affect lastbgsave_status.
Anyway, this kill is not particularly needed here, dropping the kill
is the best one, since we do have the waitForBgsave, so just let it
take care of the bgsave. No need for fast termination.

RM_Microseconds
Return the wall-clock Unix time, in microseconds
RM_CachedMicroseconds
Returns a cached copy of the Unix time, in microseconds.
It is updated in the server cron job and before executing a command.
It is useful for complex call stacks, such as a command causing a
key space notification, causing a module to execute a RedisModule_Call,
causing another notification, etc.
It makes sense that all these callbacks would use the same clock.

The reason we do this is because in #11036, we added error
log message when failing to open RDB file for reading.
In loadDdataFromDisk we call rdbLoad and also check errno,
now the logging corrupts errno (reported in alpine daily).
It is not safe to rely on errno as we do today, so we change
the return value of rdbLoad function to enums, like we have
when loading an AOF.

Fix #11030, use lua_rawget to avoid triggering metatables.
#11030 shows how return `_G` from the Lua script (either function or eval), cause the
Lua interpreter to Panic and the Redis processes to exit with error code 1.
Though return `_G` only panic on Redis 7 and 6.2.7, the underline issue exists on older
versions as well (6.0 and 6.2). The underline issue is returning a table with a metatable
such that the metatable raises an error.
The following example demonstrate the issue:
```
127.0.0.1:6379> eval "local a = {}; setmetatable(a,{__index=function() foo() end}) return a" 0
Error: Server closed the connection
```
```
PANIC: unprotected error in call to Lua API (user_script:1: Script attempted to access nonexistent global variable 'foo')
```
The Lua panic happened because when returning the result to the client, Redis needs to
introspect the returning table and transform the table into a resp. In order to scan the table,
Redis uses `lua_gettable` api which might trigger the metatable (if exists) and might raise an error.
This code is not running inside `pcall` (Lua protected call), so raising an error causes the
Lua to panic and exit. Notice that this is not a crash, its a Lua panic that exit with error code 1.
Returning `_G` panics on Redis 7 and 6.2.7 because on those versions `_G` has a metatable
that raises error when trying to fetch a none existing key.
### Solution
Instead of using `lua_gettable` that might raise error and cause the issue, use `lua_rawget`
that simply return the value from the table without triggering any metatable logic.
This is promised not to raise and error.
The downside of this solution is that it might be considered as breaking change, if someone
rely on metatable in the returned value. An alternative solution is to wrap this entire logic
with `pcall` (Lua protected call), this alternative require a much bigger refactoring.
### Back Porting
The same fix will work on older versions as well (6.2, 6.0). Notice that on those version,
the issue can cause Redis to crash if inside the metatable logic there is an attempt to accesses
Redis (`redis.call`). On 7.0, there is not crash and the `redis.call` is executed as if it was done
from inside the script itself.
### Tests
Tests was added the verify the fix

Gossip the cluster node blacklist in ping and pong messages.
This means that CLUSTER FORGET doesn't need to be sent to all nodes in a cluster.
It can be sent to one or more nodes and then be propagated to the rest of them.
For each blacklisted node, its node id and its remaining blacklist TTL is gossiped in a
cluster bus ping extension (introduced in #9530).

In rewriteAppendOnlyFileBackground, after flushAppendOnlyFile(1),
and before openNewIncrAofForAppend, we should call redis_fsync
to fsync the aof file.
Because we may open a new INCR AOF in openNewIncrAofForAppend,
in the case of using everysec policy, the old AOF file may not
be fsynced in time (or even at all).
When using everysec, we don't want to pay the disk latency from
the main thread, so we will do a background fsync.
Adding a argument for bioCreateCloseJob, a `need_fsync` flag to
indicate that a fsync is required before the file is closed. So we will
fsync the old AOF file before we close it.
A cleanup, we make union become a union, since the free_* args and
the fd / fsync args are never used together.

As an outstanding part mentioned in #10737, we could just make the cluster config file and
ACL file saving done with a more safe and atomic pattern (write to temp file, fsync, rename, fsync dir).
The cluster config file uses an in-place overwrite and truncation (which was also used by the
main config file before #7824).
The ACL file is using the temp file and rename approach, but was missing an fsync.

A timing issue like this was reported in freebsd daily CI:
```
*** [err]: Sanity test push cmd after resharding in tests/unit/cluster/cli.tcl
Expected 'CLUSTERDOWN The cluster is down' to match '*MOVED*'
```
We additionally wait for each node to reach a consensus on the cluster
state in wait_for_condition to avoid the cluster down error.
The fix just like #10495, quoting madolson's comment:
Cluster check just verifies the the config state is self-consistent,
waiting for cluster_state to be okay is an independent check that all
the nodes actually believe each other are healthy.
At the same time i noticed that unit/moduleapi/cluster.tcl has an exact
same test, may have the same problem, also modified it.

The temporary array for deleted entries reply of XAUTOCLAIM was
insufficient, but also in fact the COUNT argument should be used to
control the size of the reply, so instead of terminating the loop by
only counting the claimed entries, we'll count deleted entries as well.

replace use of:
sprintf --> snprintf
strcpy/strncpy --> redis_strlcpy
strcat/strncat --> redis_strlcat
**why are we making this change?**
Much of the code uses some unsafe variants or deprecated buffer handling
functions.
While most cases are probably not presenting any issue on the known path
programming errors and unterminated strings might lead to potential
buffer overflows which are not covered by tests.
**As part of this PR we change**
1. added implementation for redis_strlcpy and redis_strlcat based on the strl implementation: https://linux.die.net/man/3/strl
2. change all occurrences of use of sprintf with use of snprintf
3. change occurrences of use of strcpy/strncpy with redis_strlcpy
4. change occurrences of use of strcat/strncat with redis_strlcat
5. change the behavior of ll2string/ull2string/ld2string so that it will always place null
termination ('\0') on the output buffer in the first index. this was done in order to make
the use of these functions more safe in cases were the user will not check the output
returned by them (for example in rdbRemoveTempFile)
6. we added a compiler directive to issue a deprecation error in case a use of
sprintf/strcpy/strcat is found during compilation which will result in error during compile time.
However keep in mind that since the deprecation attribute is not supported on all compilers,
this is expected to fail during push workflows.
**NOTE:** while this is only an initial milestone. We might also consider
using the *_s implementation provided by the C11 Extensions (however not
yet widly supported). I would also suggest to start
looking at static code analyzers to track unsafe use cases.
For example LLVM clang checker supports security.insecureAPI.DeprecatedOrUnsafeBufferHandling
which can help locate unsafe function usage.
https://clang.llvm.org/docs/analyzer/checkers.html#security-insecureapi-deprecatedorunsafebufferhandling-c
The main reason not to onboard it at this stage is that the alternative
excepted by clang is to use the C11 extensions which are not always
supported by stdlib.

In the newly added cluster hostnames test, the primary is failing over during the reboot
for valgrind so we are validating the wrong node. This change just sets the replica to
prevent taking over, which seems to fix the test.
We could have also set the timeout higher, but it slows down the test.

According to the Redis functions documentation, FCALL command format could be
FCALL function_name numberOfKeys [key1, key2, key3.....] [arg1, arg2, arg3.....]
So in the json file of fcall and fcall_ro, we should add optional for key and arg part.
Just like EVAL...

The corrupt dump fuzzer uncovered a valgrind warning saying:
```
==76370== Argument 'size' of function malloc has a fishy (possibly negative) value: -3744781444216323815
```
This allocation would have failed (returning NULL) and being handled properly by redis (even before this change), but we also want to silence the valgrind warnings (which are checking that casting to ssize_t produces a non-negative value).
The solution i opted for is to explicitly fail these allocations (returning NULL), before even reaching `malloc` (which would have failed and return NULL too).
The implication is that we will not be able to support a single allocation of more than 2GB on a 32bit system (which i don't think is a realistic scenario).
i.e. i do think we could be facing cases were redis consumes more than 2gb on a 32bit system, but not in a single allocation.
The byproduct of this, is that i dropped the overflow assertions, since these will now lead to the same OOM panic we have for failed allocations.

In #9389, we add a new `cluster-port` config and make cluster bus port configurable,
and currently redis-cli --cluster create/add-node doesn't support with a configurable `cluster-port` instance.
Because redis-cli uses the old way (port + 10000) to send the `CLUSTER MEET` command.
Now we add this support on redis-cli `--cluster`, note we don't need to explicitly pass in the
`cluster-port` parameter, we can get the real `cluster-port` of the node in `clusterManagerNodeLoadInfo`,
so the `--cluster create` and `--cluster add-node` interfaces have not changed.
We will use the `cluster-port` when we are doing `CLUSTER MEET`, also note that `CLUSTER MEET` bus-port
parameter was added in 4.0, so if the bus_port (the one in redis-cli) is 0, or equal (port + 10000),
we just call `CLUSTER MEET` with 2 arguments, using the old form.

## Issue
During the MULTI/EXEC flow, each command gets queued until the `EXEC`
command is received and during this phase on every command queue, a
`realloc` is being invoked. This could be expensive based on the realloc
behavior (if copy to a new memory location).
## Solution
In order to reduce the no. of syscall, couple of optimization I've used.
1. By default, reserve memory for atleast two commands. `MULTI/EXEC` for a
single command doesn't have any significance. Hence, I believe customer wouldn't use it.
2. For further reservation, increase the memory allocation in exponent growth (power of 2).
This reduces the no. of `realloc` call from `N` to `log(N)` times.
## Other changes:
* Include multi exec queued command array in client memory consumption calculation
(affects client eviction too)

Currently in cluster mode, Redis process locks the cluster config file when
starting up and holds the lock for the entire lifetime of the process.
When the server shuts down, it doesn't explicitly release the lock on the
cluster config file. We noticed a problem with restart testing that if you shut down
a very large redis-server process (i.e. with several hundred GB of data stored),
it takes the OS a while to free the resources and unlock the cluster config file.
So if we immediately try to restart the redis server process, it might fail to acquire
the lock on the cluster config file and fail to come up.
This fix explicitly releases the lock on the cluster config file upon a shutdown rather
than relying on the OS to release the lock, which is a cleaner and safer approach to
free up resources acquired.
