            <title>[SERVER-64918] Add a log entry if OpMsgRequest.body is bigger than BSONObjMaxInternalSize</title>
                <link>https://jira.mongodb.org/browse/SERVER-64918</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;When creating the &lt;a href=&quot;https://github.com/mongodb/mongo/blob/c83e50d7275adf2a5e946ba2c4b0861fcd9dc69b/src/mongo/rpc/op_msg.h#L165-L170&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;&lt;tt&gt;body&lt;/tt&gt; of &lt;tt&gt;OpMsgRequest&lt;/tt&gt;&lt;/a&gt; it&apos;s possible that the combination of &lt;a href=&quot;https://github.com/mongodb/mongo/blob/c83e50d7275adf2a5e946ba2c4b0861fcd9dc69b/src/mongo/rpc/op_msg.h#L166&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;&lt;tt&gt;body&lt;/tt&gt;&lt;/a&gt;, &lt;a href=&quot;https://github.com/mongodb/mongo/blob/c83e50d7275adf2a5e946ba2c4b0861fcd9dc69b/src/mongo/rpc/op_msg.h#L167&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;&lt;tt&gt;extraFields&lt;/tt&gt;&lt;/a&gt; and &lt;a href=&quot;https://github.com/mongodb/mongo/blob/c83e50d7275adf2a5e946ba2c4b0861fcd9dc69b/src/mongo/rpc/op_msg.h#L168&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;&lt;tt&gt;$db&lt;/tt&gt;&lt;/a&gt; goes beyond &lt;a href=&quot;https://github.com/mongodb/mongo/blob/f6d863188b71b420f13b8249579d34de76d80d9c/src/mongo/bson/util/builder.h#L71&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;&lt;tt&gt;BSONObjMaxInternalSize&lt;/tt&gt;&lt;/a&gt;. In this case, currently, only an &lt;a href=&quot;https://github.com/mongodb/mongo/blob/e2de2b23e821614a8c3117fa8650b910f44c7638/src/mongo/bson/bsonobj.cpp#L87-L99&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;assertion failure&lt;/a&gt; is issued. However, to improve the situation and help our support team with more useful data, we&apos;d better log the size break-down of these fields (and even include the truncated values for them):&lt;/p&gt;

&lt;p&gt;Here&apos;s a suggested change for &lt;a href=&quot;https://github.com/mongodb/mongo/blob/c83e50d7275adf2a5e946ba2c4b0861fcd9dc69b/src/mongo/rpc/op_msg.h#L165-L170&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;here&lt;/a&gt;:&lt;/p&gt;

This metadata should only appear in requests from mongos to mongod.&lt;/p&gt;

&lt;p&gt;There are already some tests to make sure that manually inserted impersonations can&apos;t escalate privileges:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;&lt;a href=&quot;https://github.com/10gen/mongo/blob/ad84ff45e2a7abbdcd782d9cde97d098711f99bf/jstests/auth/impersonation-deny.js&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/10gen/mongo/blob/ad84ff45e2a7abbdcd782d9cde97d098711f99bf/jstests/auth/impersonation-deny.js&lt;/a&gt;&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;You can take a look at these code blocks:&lt;/p&gt;
&lt;ul&gt;
	&lt;li&gt;&lt;a href=&quot;https://github.com/10gen/mongo/blob/80fd26faeae107c073f46ff00f3407562e6ed17b/src/mongo/rpc/metadata/impersonated_user_metadata.idl#L38-L47&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/10gen/mongo/blob/80fd26faeae107c073f46ff00f3407562e6ed17b/src/mongo/rpc/metadata/impersonated_user_metadata.idl#L38-L47&lt;/a&gt;&#160;&lt;/li&gt;
	&lt;li&gt;&lt;a href=&quot;https://github.com/10gen/mongo/blob/102cc8aeb299faadd9349c3ffd23f7ca9ff3c32b/src/mongo/db/audit.h#L70-L84&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/10gen/mongo/blob/102cc8aeb299faadd9349c3ffd23f7ca9ff3c32b/src/mongo/db/audit.h#L70-L84&lt;/a&gt;&#160;&lt;/li&gt;
&lt;/ul&gt;


&lt;ul&gt;
	&lt;li&gt;
	&lt;ul&gt;
		&lt;li&gt;&lt;em&gt;Struct that temporarily stores client information when an audit hook executes on a separate thread with a new Client. In those cases, ImpersonatedClientAttrs can bundle all relevant client attributes necessary for auditing and be safely passed into the new thread, where the new Client will be loaded with the userNames and roleNames stored in ImpersonatedClientAttrs.&lt;/em&gt;&lt;/li&gt;
	&lt;/ul&gt;
	&lt;/li&gt;
&lt;/ul&gt;


&lt;ul&gt;
	&lt;li&gt;&lt;a href=&quot;https://github.com/10gen/mongo/blob/13e435912a9880d265ec400e921e8a3743b13c65/src/mongo/db/index_builds_coordinator_mongod.cpp#L308-L310&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/10gen/mongo/blob/13e435912a9880d265ec400e921e8a3743b13c65/src/mongo/db/index_builds_coordinator_mongod.cpp#L308-L310&lt;/a&gt;&#160;&lt;/li&gt;
&lt;/ul&gt;


&lt;ul&gt;
	&lt;li&gt;
	&lt;ul&gt;
		&lt;li&gt;&lt;em&gt;Since index builds occur in a separate thread, client attributes that are audited must be extracted from the client object and passed into the thread separately.&lt;/em&gt;&lt;/li&gt;
	&lt;/ul&gt;
	&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;Now, with the possibility of a large number of roles, we need to rethink this and either account for the size of impersonation data while creating the BSON request object, or set a limit on the size of impersonation data that can be included (and if it goes beyond the limit, we need to find another way (e.g., spilling to disk) for communication). The former solution does not seem feasible, as we want to be able to continue supporting 16MB user documents (i.e., &lt;tt&gt;BSONObjMaxUserSize&lt;/tt&gt;), which only leaves a rigid 16KB for the rest of meta-data (i.e., &lt;tt&gt;BSONObjMaxUserSize&lt;/tt&gt;).&lt;/p&gt;</comment>

&lt;ul&gt;
	&lt;li&gt;Should we schedule this ticket soon to help better understand the issue?&lt;/li&gt;
	&lt;li&gt;Do we want to consider changing the things we want to include in OpMsgRequest? Like not including all the user roles in the request? You can refer to Mohammad&apos;s comment in the linked HELP ticket for more information.&lt;/li&gt;
