      Fix protocol parsing on 'ldbReplParseCommand' (CVE-2021-32672) (#9590) · b0ca3be2
      Oran Agra authored
      
      
      The protocol parsing on 'ldbReplParseCommand' (LUA debugging)
      Assumed protocol correctness. This means that if the following
      is given:
      *1
      $100
      test
      The parser will try to read additional 94 unallocated bytes after
      the client buffer.
      This commit fixes this issue by validating that there are actually enough
      bytes to read. It also limits the amount of data that can be sent by
      the debugger client to 1M so the client will not be able to explode
      the memory.

      Unified Lua and modules reply parsing and added RESP3 support to RM_Call (#9202) · 2237131e
      Meir Shpilraien (Spielrein) authored
      
      
      ## Current state
      1. Lua has its own parser that handles parsing `reds.call` replies and translates them
        to Lua objects that can be used by the user Lua code. The parser partially handles
        resp3 (missing big number, verbatim, attribute, ...)
      2. Modules have their own parser that handles parsing `RM_Call` replies and translates
        them to RedisModuleCallReply objects. The parser does not support resp3.
      
      In addition, in the future, we want to add Redis Function (#8693) that will probably
      support more languages. At some point maintaining so many parsers will stop
      scaling (bug fixes and protocol changes will need to be applied on all of them).
      We will probably end up with different parsers that support different parts of the
      resp protocol (like we already have today with Lua and modules)
      
      ## PR Changes
      This PR attempt to unified the reply parsing of Lua and modules (and in the future
      Redis Function) by introducing a new parser unit (`resp_parser.c`). The new parser
      handles parsing the reply and calls different callbacks to allow the users (another
      unit that uses the parser, i.e, Lua, modules, or Redis Function) to analyze the reply.
      
      ### Lua API Additions
      The code that handles reply parsing on `scripting.c` was removed. Instead, it uses
      the resp_parser to parse and create a Lua object out of the reply. As mentioned
      above the Lua parser did not handle parsing big numbers, verbatim, and attribute.
      The new parser can handle those and so Lua also gets it for free.
      Those are translated to Lua objects in the following way:
      1. Big Number - Lua table `{'big_number':'<str representation for big number>'}`
      2. Verbatim - Lua table `{'verbatim_string':{'format':'<verbatim format>', 'string':'<verbatim string value>'}}`
      3. Attribute - currently ignored and not expose to the Lua parser, another issue will be open to decide how to expose it.
      
      Tests were added to check resp3 reply parsing on Lua
      
      ### Modules API Additions
      The reply parsing code on `module.c` was also removed and the new resp_parser is used instead.
      In addition, the RedisModuleCallReply was also extracted to a separate unit located on `call_reply.c`
      (in the future, this unit will also be used by Redis Function). A nice side effect of unified parsing is
      that modules now also support resp3. Resp3 can be enabled by giving `3` as a parameter to the
      fmt argument of `RM_Call`. It is also possible to give `0`, which will indicate an auto mode. i.e, Redis
      will automatically chose the reply protocol base on the current client set on the RedisModuleCtx
      (this mode will mostly be used when the module want to pass the reply to the client as is).
      In addition, the following RedisModuleAPI were added to allow analyzing resp3 replies:
      
      * New RedisModuleCallReply types:
         * `REDISMODULE_REPLY_MAP`
         * `REDISMODULE_REPLY_SET`
         * `REDISMODULE_REPLY_BOOL`
         * `REDISMODULE_REPLY_DOUBLE`
         * `REDISMODULE_REPLY_BIG_NUMBER`
         * `REDISMODULE_REPLY_VERBATIM_STRING`
         * `REDISMODULE_REPLY_ATTRIBUTE`
      
      * New RedisModuleAPI:
         * `RedisModule_CallReplyDouble` - getting double value from resp3 double reply
         * `RedisModule_CallReplyBool` - getting boolean value from resp3 boolean reply
         * `RedisModule_CallReplyBigNumber` - getting big number value from resp3 big number reply
         * `RedisModule_CallReplyVerbatim` - getting format and value from resp3 verbatim reply
         * `RedisModule_CallReplySetElement` - getting element from resp3 set reply
         * `RedisModule_CallReplyMapElement` - getting key and value from resp3 map reply
         * `RedisModule_CallReplyAttribute` - getting a reply attribute
         * `RedisModule_CallReplyAttributeElement` - getting key and value from resp3 attribute reply
         
      * New context flags:
         * `REDISMODULE_CTX_FLAGS_RESP3` - indicate that the client is using resp3
      
      Tests were added to check the new RedisModuleAPI
      
      ### Modules API Changes
      * RM_ReplyWithCallReply might return REDISMODULE_ERR if the given CallReply is in resp3
        but the client expects resp2. This is not a breaking change because in order to get a resp3
        CallReply one needs to specifically specify `3` as a parameter to the fmt argument of
        `RM_Call` (as mentioned above).
      
      Tests were added to check this change
      
      ### More small Additions
      * Added `debug set-disable-deny-scripts` that allows to turn on and off the commands no-script
      flag protection. This is used by the Lua resp3 tests so it will be possible to run `debug protocol`
      and check the resp3 parsing code.

      Fixed some typos, add a spell check ci and others minor fix (#8890) · 0bfccc55
      Binbin authored
      This PR adds a spell checker CI action that will fail future PRs if they introduce typos and spelling mistakes.
      This spell checker is based on blacklist of common spelling mistakes, so it will not catch everything,
      but at least it is also unlikely to cause false positives.
      
      Besides that, the PR also fixes many spelling mistakes and types, not all are a result of the spell checker we use.
      
      Here's a summary of other changes:
      1. Scanned the entire source code and fixes all sorts of typos and spelling mistakes (including missing or extra spaces).
      2. Outdated function / variable / argument names in comments
      3. Fix outdated keyspace masks error log when we check `config.notify-keyspace-events` in loadServerConfigFromString.
      4. Trim the white space at the end of line in `module.c`. Check: https://github.com/redis/redis/pull/7751
      5. Some outdated https link URLs.
      6. Fix some outdated comment. Such as:
          - In README: about the rdb, we used to said create a `thread`, change to `process`
          - dbRandomKey function coment (about the dictGetRandomKey, change to dictGetFairRandomKey)
          - notifyKeyspaceEvent fucntion comment (add type arg)
          - Some others minor fix in comment (Most of them are incorrectly quoted by variable names)
      7. Modified the error log so that users can easily distinguish between TCP and TLS in `changeBindAddr`

      Improve test suite to handle external servers better. (#9033) · 8a86bca5
      Yossi Gottlieb authored
      This commit revives the improves the ability to run the test suite against
      external servers, instead of launching and managing `redis-server` processes as
      part of the test fixture.
      
      This capability existed in the past, using the `--host` and `--port` options.
      However, it was quite limited and mostly useful when running a specific tests.
      Attempting to run larger chunks of the test suite experienced many issues:
      
      * Many tests depend on being able to start and control `redis-server` themselves,
      and there's no clear distinction between external server compatible and other
      tests.
      * Cluster mode is not supported (resulting with `CROSSSLOT` errors).
      
      This PR cleans up many things and makes it possible to run the entire test suite
      against an external server. It also provides more fine grained controls to
      handle cases where the external server supports a subset of the Redis commands,
      limited number of databases, cluster mode, etc.
      
      The tests directory now contains a `README.md` file that describes how this
      works.
      
      This commit also includes additional cleanups and fixes:
      
      * Tests can now be tagged.
      * Tag-based selection is now unified across `start_server`, `tags` and `test`.
      * More information is provided about skipped or ignored tests.
      * Repeated patterns in tests have been extracted to common procedures, both at a
        global level and on a per-test file basis.
      * Cleaned up some cases where test setup was based on a previous test executing
        (a major anti-pattern that repeats itself in many places).
      * Cleaned up some cases where test teardown was not part of a test (in the
        future we should have dedicated teardown code that executes even when tests
        fail).
      * Fixed some tests that were flaky running on external servers.

      Fix script kill to work also on scripts that use pcall (#8661) · 9ae4f5c7
      Meir Shpilraien (Spielrein) authored
      pcall function runs another LUA function in protected mode, this means
      that any error will be caught by this function and will not stop the LUA
      execution. The script kill mechanism uses error to stop the running script.
      Scripts that uses pcall can catch the error raise by the script kill mechanism,
      this will cause a script like this to be unkillable:
      
      local f = function()
              while 1 do
                      redis.call('ping')
              end
      end
      while 1 do
              pcall(f)
      end
      
      The fix is, when we want to kill the script, we set the hook function to be invoked 
      after each line. This will promise that the execution will get another
      error before it is able to enter the pcall function again.

      minor test suite cleanup, revive old test (#8497) · fb3457d1
      Oran Agra authored
      There are two tests in other.tcl that were dependant of the sha1 package
      import which meant that they didn't usually run.
      The reason it was like that was that prior to the creation of DEBUG
      DIGEST, the test suite used to have an equivalent function, but that's
      no longer the case and this dependency isn't needed.
      
      The other change is to revert config changes done by the test before the
      test suite continues. can be useful if using `--host` to run multiple
      units against the same server

      Fix wrong order of key/value in Lua map response (#8266) · 2017407b
      Oran Agra authored
      When a Lua script returns a map to redis (a feature which was added in
      redis 6 together with RESP3), it would have returned the value first and
      the key second.
      
      If the client was using RESP2, it was getting them out of order, and if
      the client was in RESP3, it was getting a map of value => key.
      This was happening regardless of the Lua script using redis.setresp(3)
      or not.
      
      This also affects a case where the script was returning a map which it got
      from from redis by doing something like: redis.setresp(3); return redis.call()
      
      This fix is a breaking change for redis 6.0 users who happened to rely
      on the wrong order (either ones that used redis.setresp(3), or ones that
      returned a map explicitly).
      
      This commit also includes other two changes in the tests:
      1. The test suite now handles RESP3 maps as dicts rather than nested
         lists
      2. Remove some redundant (duplicate) tests from tracking.tcl

      Unified MULTI, LUA, and RM_Call with respect to blocking commands (#8025) · d87a0d02
      Meir Shpilraien (Spielrein) authored
      
      
      Blocking command should not be used with MULTI, LUA, and RM_Call. This is because,
      the caller, who executes the command in this context, expects a reply.
      
      Today, LUA and MULTI have a special (and different) treatment to blocking commands:
      
      LUA   - Most commands are marked with no-script flag which are checked when executing
      and command from LUA, commands that are not marked (like XREAD) verify that their
      blocking mode is not used inside LUA (by checking the CLIENT_LUA client flag).
      MULTI - Command that is going to block, first verify that the client is not inside
      multi (by checking the CLIENT_MULTI client flag). If the client is inside multi, they
      return a result which is a match to the empty key with no timeout (for example blpop
      inside MULTI will act as lpop)
      For modules that perform RM_Call with blocking command, the returned results type is
      REDISMODULE_REPLY_UNKNOWN and the caller can not really know what happened.
      
      Disadvantages of the current state are:
      
      No unified approach, LUA, MULTI, and RM_Call, each has a different treatment
      Module can not safely execute blocking command (and get reply or error).
      Though It is true that modules are not like LUA or MULTI and should be smarter not
      to execute blocking commands on RM_Call, sometimes you want to execute a command base
      on client input (for example if you create a module that provides a new scripting
      language like javascript or python).
      While modules (on modules command) can check for REDISMODULE_CTX_FLAGS_LUA or
      REDISMODULE_CTX_FLAGS_MULTI to know not to block the client, there is no way to
      check if the command came from another module using RM_Call. So there is no way
      for a module to know not to block another module RM_Call execution.
      
      This commit adds a way to unify the treatment for blocking clients by introducing
      a new CLIENT_DENY_BLOCKING client flag. On LUA, MULTI, and RM_Call the new flag
      turned on to signify that the client should not be blocked. A blocking command
      verifies that the flag is turned off before blocking. If a blocking command sees
      that the CLIENT_DENY_BLOCKING flag is on, it's not blocking and return results
      which are matches to empty key with no timeout (as MULTI does today).
      
      The new flag is checked on the following commands:
      
      List blocking commands: BLPOP, BRPOP, BRPOPLPUSH, BLMOVE,
      Zset blocking commands: BZPOPMIN, BZPOPMAX
      Stream blocking commands: XREAD, XREADGROUP
      SUBSCRIBE, PSUBSCRIBE, MONITOR
      In addition, the new flag is turned on inside the AOF client, we do not want to
      block the AOF client to prevent deadlocks and commands ordering issues (and there
      is also an existing assert in the code that verifies it).
      
      To keep backward compatibility on LUA, all the no-script flags on existing commands
      were kept untouched. In addition, a LUA special treatment on XREAD and XREADGROUP was kept.
      
      To keep backward compatibility on MULTI (which today allows SUBSCRIBE, and PSUBSCRIBE).
      We added a special treatment on those commands to allow executing them on MULTI.
      
      The only backward compatibility issue that this PR introduces is that now MONITOR
      is not allowed inside MULTI.
      
      Tests were added to verify blocking commands are not blocking the client on LUA, MULTI,
      or RM_Call. Tests were added to verify the module can check for CLIENT_DENY_BLOCKING flag.

      Scripting: handle trailing comments. · f43c794b
      antirez authored
      This fix, provided by Paul Kulchenko (@pkulchenko), allows the Lua
      scripting engine to evaluate statements with a trailing comment like the
      following one:
      
          EVAL "print() --comment" 0
      
      Lua can't parse the above if the string does not end with a newline, so
      now a final newline is always added automatically. This does not change
      the SHA1 of scripts since the SHA1 is computed on the body we pass to
      EVAL, without the other code we add to register the function.
      
      Close #2951.

      Added <count> parameter to SPOP: · 28802887
      Alon Diamant authored
      spopCommand() now runs spopWithCountCommand() in case the <count> param is found.
      Added intsetRandomMembers() to Intset: Copies N random members from the set into inputted 'values' array. Uses either the Knuth or Floyd sample algos depending on ratio count/size.
      Added setTypeRandomElements() to SET type: Returns a number of random elements from a non empty set. This is a version of setTypeRandomElement() that is modified in order to return multiple entries, using dictGetRandomKeys() and intsetRandomMembers().
      Added tests for SPOP with <count>: unit/type/set, unit/scripting, integration/aof
      --
      Cleaned up code a bit to match with required Redis coding style

      Lua: add cmsgpack scripting tests · ace628c7
      Matt Stancliff authored
      Basically: test to make sure we can load cmsgpack
      and do some sanity checks to make sure pack/unpack works
      properly.  We also have a bonus test for circular encoding
      and decoding because I was curious how it worked.

      This adds bitop 1.0.2 (2012-05-08) from http://bitop.luajit.org/
      
      bitop is imported as "bit" into the global namespace.
      
      New Lua commands: bit.tobit, bit.tohex, bit.bnot, bit.band, bit.bor, bit.bxor,
      bit.lshift, bit.rshift, bit.arshift, bit.rol, bit.ror, bit.bswap
      
      Verification of working (the asserts would abort on error, so (nil) is correct):
      127.0.0.1:6379> eval "assert(bit.tobit(1) == 1); assert(bit.band(1) == 1); assert(bit.bxor(1,2) == 3); assert(bit.bor(1,2,4,8,16,32,64,128) == 255)" 0
      (nil)
      127.0.0.1:6379> eval 'assert(0x7fffffff == 2147483647, "broken hex literals"); assert(0xffffffff == -1 or 0xffffffff == 2^32-1, "broken hex literals"); assert(tostring(-1) == "-1", "broken tostring()"); assert(tostring(0xffffffff) == "-1" or tostring(0xffffffff) == "4294967295", "broken tostring()")' 0
      (nil)
      
      Tests also integrated into the scripting tests and can be run with:
      ./runtest --single unit/scripting
      
      Tests are excerpted from `bittest.lua` included in the bitop distribution.

      Fix semantics of Lua calls to SELECT. · 96e0fe62
      antirez authored
      Lua scripts are executed in the context of the currently selected
      database (as selected by the caller of the script).
      
      However Lua scripts are also free to use the SELECT command in order to
      affect other DBs. When SELECT is called frm Lua, the old behavior, before
      this commit, was to automatically set the Lua caller selected DB to the
      last DB selected by Lua. See for example the following sequence of
      commands:
      
          SELECT 0
          SET x 10
          EVAL "redis.call('select','1')" 0
          SET x 20
      
      Before this commit after the execution of this sequence of commands,
      we'll have x=10 in DB 0, and x=20 in DB 1.
      
      Because of the problem above, there was a bug affecting replication of
      Lua scripts, because of the actual implementation of replication. It was
      possible to fix the implementation of Lua scripts in order to fix the
      issue, but looking closely, the bug is the consequence of the behavior
      of Lua ability to set the caller's DB.
      
      Under the old semantics, a script selecting a different DB, has no simple
      ways to restore the state and select back the previously selected DB.
      Moreover the script auhtor must remember that the restore is needed,
      otherwise the new commands executed by the caller, will be executed in
      the context of a different DB.
      
      So this commit fixes both the replication issue, and this hard-to-use
      semantics, by removing the ability of Lua, after the script execution,
      to force the caller to switch to the DB selected by the Lua script.
      
      The new behavior of the previous sequence of commadns is to just set
      X=20 in DB 0. However Lua scripts are still capable of writing / reading
      from different DBs if needed.
      
      WARNING: This is a semantical change that will break programs that are
      conceived to select the client selected DB via Lua scripts.
      
      This fixes issue #1811.

      Scripting: Fix regression from #1118 · 76efe122
      Matt Stancliff authored
      The new check-for-number behavior of Lua arguments broke
      users who use large strings of just integers.
      
      The Lua number check would convert the string to a number, but
      that breaks user data because
      Lua numbers have limited precision compared to an arbitrarily
      precise number wrapped in a string.
      
      Regression fixed and new test added.
      
      Fixes #1118 again.

      Scripting test: check that Lua can call commands rewirting argv. · 76c31d42
      antirez authored
      SPOP, tested in the new test, is among the commands rewritng the
      client->argv argument vector (it gets rewritten as SREM) for command
      replication purposes.
      
      Because of recent optimizations to client->argv caching in the context
      of the Lua internal Redis client, it is important to test for SPOP to be
      callable from Lua without bad effects to the other commands.
