RevokeSecurityGroupEgress and AuthorizeSecurityGroupEgress requests not working #2559

awatterson22 · 2024-03-15T18:18:20Z

Acknowledgements

I have searched (https://github.com/aws/aws-sdk/issues?q=is%3Aissue) for past instances of this issue
I have verified all of my SDK modules are up-to-date (you can perform a bulk update with go get -u github.com/aws/aws-sdk-go-v2/...)

Describe the bug

When running this file:

Note: sg-fake-id is not what is actually used but a real security group id from the AWS Console is used

package main

import (
	"context"
	"fmt"

	"github.com/aws/aws-sdk-go-v2/aws"
	"github.com/aws/aws-sdk-go-v2/config"
	"github.com/aws/aws-sdk-go-v2/service/ec2"
	"github.com/aws/aws-sdk-go-v2/service/ec2/types"
)

func main() {
	cfg, err := config.LoadDefaultConfig(context.TODO(), config.WithRegion("us-east-1"))
	if err != nil {
		panic(err)
	}

	client := ec2.NewFromConfig(cfg)

	output, _ := client.DescribeSecurityGroups(context.TODO(), &ec2.DescribeSecurityGroupsInput{
		Filters: []types.Filter{
			{
				Name:   aws.String("group-id"),
				Values: []string{"sg-fake-id"},
			},
		},
	})

	sg := output.SecurityGroups[0]

	revokeInput := &ec2.RevokeSecurityGroupEgressInput{
		GroupId:       sg.GroupId,
		IpPermissions: sg.IpPermissionsEgress,
	}

	stuff, err := client.RevokeSecurityGroupEgress(context.TODO(), revokeInput)
	if err != nil {
		fmt.Println("Error", err)
		return
	}
	fmt.Println(stuff)

	fmt.Println("Egress successfully revoked")

	authorizeInput := &ec2.AuthorizeSecurityGroupEgressInput{
		GroupId:       sg.GroupId,
		IpPermissions: sg.IpPermissionsEgress,
	}

	_, err = client.AuthorizeSecurityGroupEgress(context.TODO(), authorizeInput)
	if err != nil {
		fmt.Println("Error", err)
		return
	}

	fmt.Println("Egress successfully authorized")
}

I get an error saying

Error operation error EC2: RevokeSecurityGroupEgress, https response error StatusCode: 400, RequestID: *******, api error InvalidRequest: The request received was invalid.

Or

Error operation error EC2: AuthorizeSecurityGroupEgress, https response error StatusCode: 400, RequestID: *******, api error InvalidRequest: The request received was invalid.

Expected Behavior

I expected to be able to revoke all the egress rules from the security group after getting them from the describe command. This logic works for aws-sdk-go, but I am trying to upgrade to aws-sdk-go-v2

Current Behavior

I am getting an error saying

Error operation error EC2: RevokeSecurityGroupEgress, https response error StatusCode: 400, RequestID: *******, api error InvalidRequest: The request received was invalid.

Or

Error operation error EC2: AuthorizeSecurityGroupEgress, https response error StatusCode: 400, RequestID: *******, api error InvalidRequest: The request received was invalid.

Reproduction Steps

Can be reproduced by running the script above

Hi @awatterson22 - thanks for reaching out and sorry to hear about the issue.

The errors you're seeing indicate that you might have some params that are invalid for RevokeSecurityGroupEgress and AuthorizeSecurityGroupEgress.

For further investigation, can you please enable request and response logging and share with us here?

	cfg, err := config.LoadDefaultConfig(context.TODO(), config.WithRegion("us-east-1"), config.WithClientLogMode(aws.LogRequestWithBody|aws.LogResponseWithBody))
	if err != nil {
		panic(err)
	}

Best,
John

@aBurmeseDev - any updates on this issue? Thank you!

aBurmeseDev · 2024-04-04T02:30:44Z

HI @awatterson22 - thanks for sharing the logs and apology for the delay.

I've attempted to reproduce by calling RevokeSecurityGroupEgress and AuthorizeSecurityGroupEgress by entering required params to each call and was able to make the requests successfully.

According to the logs and error, it confirms that you have invalid params for both calls (RevokeSecurityGroupEgress & AuthorizeSecurityGroupEgress) and looking at your code, both calls receive their params from DescribeSecurityGroups call.

	output, _ := client.DescribeSecurityGroups(context.TODO(), &ec2.DescribeSecurityGroupsInput{
		Filters: []types.Filter{
			{
				Name:   aws.String("group-id"),
				Values: []string{"sg-fake-id"},
			},
		},
	})

	sg := output.SecurityGroups[0]

	revokeInput := &ec2.RevokeSecurityGroupEgressInput{
		GroupId:       sg.GroupId,
		IpPermissions: sg.IpPermissionsEgress,
	}

Next step is to confirm if you're actually getting your params correctly from DescribeSecurityGroups and your Filter. Also please note that IpPermissions would be an array of IpPermission objects. I would check that to make sure you're passing correct type.
Hope it helps,
John

awatterson22 · 2024-04-08T13:49:12Z

@aBurmeseDev, so I did take a look at what I am getting back from DescribeSecurityGroups. The GroupId is correct. When looking at it I get only 2 items, but in the AWS Console, there are 3 items. Maybe that could be why? This is what the RevokeSecurityGroupEgress is sending:

Action=RevokeSecurityGroupEgress
&GroupId=*******
&IpPermissions.1.FromPort=1025
&IpPermissions.1.Groups.1.GroupId=*******
&IpPermissions.1.Groups.1.UserId=*******
&IpPermissions.1.IpProtocol=tcp
&IpPermissions.1.IpRanges=
&IpPermissions.1.Ipv6Ranges=
&IpPermissions.1.PrefixListIds=
&IpPermissions.1.ToPort=65535
&IpPermissions.2.FromPort=443
&IpPermissions.2.Groups.1.GroupId=*******
&IpPermissions.2.Groups.1.UserId=*******
&IpPermissions.2.IpProtocol=tcp
&IpPermissions.2.IpRanges=
&IpPermissions.2.Ipv6Ranges=
&IpPermissions.2.PrefixListIds.1.PrefixListId=*******
&IpPermissions.2.ToPort=443
&Version=2016-11-15

I looped through and changed to this:

package main

import (
	"context"
	"fmt"

	"github.com/aws/aws-sdk-go-v2/aws"
	"github.com/aws/aws-sdk-go-v2/config"
	"github.com/aws/aws-sdk-go-v2/service/ec2"
	"github.com/aws/aws-sdk-go-v2/service/ec2/types"
)

func main() {
	cfg, err := config.LoadDefaultConfig(context.TODO(), config.WithRegion("us-east-1"))
	if err != nil {
		panic(err)
	}

	client := ec2.NewFromConfig(cfg)

	output, _ := client.DescribeSecurityGroups(context.TODO(), &ec2.DescribeSecurityGroupsInput{
		Filters: []types.Filter{
			{
				Name:   aws.String("group-id"),
				Values: []string{"********"},
			},
		},
	})

	sg := output.SecurityGroups[0]

	ipPermissions := []types.IpPermission{}
	for _, ipPermission := range sg.IpPermissionsEgress {
		item := types.IpPermission{
			FromPort:   ipPermission.FromPort,
			ToPort:     ipPermission.ToPort,
			IpProtocol: ipPermission.IpProtocol,
		}
		if len(ipPermission.IpRanges) > 0 {
			item.IpRanges = ipPermission.IpRanges
		}
		if len(ipPermission.Ipv6Ranges) > 0 {
			item.Ipv6Ranges = ipPermission.Ipv6Ranges
		}
		if len(ipPermission.PrefixListIds) > 0 {
			item.PrefixListIds = ipPermission.PrefixListIds
		}
		if len(ipPermission.UserIdGroupPairs) > 0 {
			item.UserIdGroupPairs = ipPermission.UserIdGroupPairs
		}
		ipPermissions = append(ipPermissions, item)
	}

	revokeInput := &ec2.RevokeSecurityGroupEgressInput{
		GroupId:       sg.GroupId,
		IpPermissions: ipPermissions,
	}

	_, err = client.RevokeSecurityGroupEgress(context.TODO(), revokeInput)
	if err != nil {
		fmt.Println("Error", err)
		return
	}

	fmt.Println("Egress successfully revoked")

        authorizeInput := &ec2.AuthorizeSecurityGroupEgressInput{
		GroupId:       sg.GroupId,
		IpPermissions: ipPermissions,
	}

	_, err = client.AuthorizeSecurityGroupEgress(context.TODO(), authorizeInput)
	if err != nil {
		fmt.Println("Error", err)
		return
	}

	fmt.Println("Egress successfully authorized")
}

Revoke and Authorize then worked. Is it possible that we could allow empty lists as part of the validation?

lucix-aws · 2024-04-18T21:47:41Z

This breaks down like so:

v1 and v2 serialization behaviors are the same. nil slice doesn't get encoded, nonnil len=0 slice gets encoded as list= (explicitly there, empty string)
v1 and v2 deserialization behaviors are different. v1 does not mutate the list field value (as in, it just leaves it nil) if the xml node that represents the list doesn't have children like we saw in the ec2 response. v2 will set it to an empty slice if the node is present. the slice would only remain nil in v2 if the node for the list is not present

The latter is the root cause here. We can see from the wire log that the DescribeSecurityGroups response encodes several empty lists within the IpPermission structure as self-closing XML nodes (e.g. <ipRanges/>). In v1, the fields that correspond to these elements come back to you the caller left as nil. In v2 they instead come back as []<type>{}. You round-trip that structure into the followup request and for reasons unknown to us, the EC2 service apparently does not accept the latter.

Changing v2's deserialization to match v1's isn't out of the question, but of course that could technically break something else.

v2's deserialization is arguably more correct. Ignoring that the difference doesn't matter in go, v2 correctly handles the distinction between "empty list" and "no list" as it comes back on the wire. As a Go SDK user you won't care though, and since this particular protocol is used only in EC2, I'm including it here as an option.

Upstreaming this to EC2 is the only other way forward. I don't think their software should care about the difference between the two, at least for these particular operations, but it's impossible to know without asking them directly.

lucix-aws · 2024-05-02T17:26:48Z

The change we previously made to serialize empty lists should have only applied to awsQuery services, not ec2Query. Will be resolved by addressing #2627.
