[Filebeat] TCP/UDP input cause a panic on Linux under certain conditions #35064

belimawr · 2023-04-12T10:37:38Z

Version: v8.7.0, main
Operating System: Linux

Steps to Reproduce

Start Filebeat with UDP input (or any input that uses UDP, like syslog)

filebeat.inputs:
- type: udp
  host: "localhost:9009"

output.console:
  enabled: true

Wait for about a minute (no need to ingest any data), you'll see a panic

panic: runtime error: index out of range [1] with length 0

goroutine 62 [running]:
github.com/elastic/beats/v7/filebeat/input/udp.procNetUDP({0xc0002b0980?, 0x1, 0x2})
        /home/tiago/devel/beats/filebeat/input/udp/input.go:271 +0x552
github.com/elastic/beats/v7/filebeat/input/udp.(*inputMetrics).poll(0xc000458680, {0xc0002b0980, 0x1, 0x2}, 0x0?, 0xc00066e040)
        /home/tiago/devel/beats/filebeat/input/udp/input.go:242 +0xd1

        /home/tiago/devel/beats/filebeat/input/udp/input.go:216 +0xa70

The problem

The panic comes from the procNetUDP function that gathers some UDP metrics from /proc/net/udp:

beats/filebeat/input/udp/input.go

Lines 256 to 288 in a8dbc6c

    
           // procNetUDP returns the rx_queue and drops field of the UDP socket table 
        
           // for the socket on the provided address formatted in hex, xxxxxxxx:xxxx. 
        
           // This function is only useful on linux due to its dependence on the /proc 
        
           // filesystem, but is kept in this file for simplicity. 
        
           func procNetUDP(addr []string) (rx, drops int64, err error) { 
        
           	b, err := os.ReadFile("/proc/net/udp") 
        
           	if err != nil { 
        
           		return 0, 0, err 
        
           	} 
        
           	lines := bytes.Split(b, []byte("\n")) 
        
           	if len(lines) < 2 { 
        
           		return 0, 0, fmt.Errorf("/proc/net/udp entry not found for %s (no line)", addr) 
        
           	} 
        
           	for _, l := range lines[1:] { 
        
           		f := bytes.Fields(l) 
        
           		if contains(f[1], addr) { 
        
           			_, r, ok := bytes.Cut(f[4], []byte(":")) 
        
           			if !ok { 
        
           				return 0, 0, errors.New("no rx_queue field " + string(f[4])) 
        
           			} 
        
           			rx, err = strconv.ParseInt(string(r), 16, 64) 
        
           			if err != nil { 
        
           				return 0, 0, fmt.Errorf("failed to parse rx_queue: %w", err) 
        
           			} 
        
           			drops, err = strconv.ParseInt(string(f[12]), 16, 64) 
        
           			if err != nil { 
        
           				return 0, 0, fmt.Errorf("failed to parse drops: %w", err) 
        
           			} 
        
           			return rx, drops, nil 
        
           		} 
        
           	} 
        
           	return 0, 0, fmt.Errorf("/proc/net/udp entry not found for %s", addr) 
        
           }

It seems some times the data is on a format different than what the function expects.

Workaround

Currently the only know workaround is to downgrade to v8.6.2.

I am getting panics in filebeat 8.8.0 with the following message:

panic is not occurring in 8.7.1 - so I've downgraded to that.
8.7.1 is not parsing /proc/net/tcp6 and the backtrace shows this is the path panicking in 8.8.0 https://github.com/elastic/beats/blob/v8.8.0/filebeat/input/tcp/input.go#LL267C1-L267C88

mmguero · 2023-05-31T16:19:50Z

Same for me. Was fixed in 8.7.1, broken again in 8.8.0.

efd6 · 2023-05-31T21:27:50Z

The issue here is a typo in the param name to containsUnspecifiedAddr in the tcp package. The same error does not exist in the udp package. Sending a fix.

mmguero · 2023-06-12T14:39:58Z

Apologies if I'm just not looking in the right place, do you know if this fix is in the recent v8.8.1 release? I looked here but didn't see it referenced.

jlind23 · 2023-06-12T14:53:34Z

@mmguero I don't think it is, it has been merged last week #35637 so it missed the deadline.
I let @efd6 comment back if needed.

….8.1)" see elastic/beats#35064 (comment) This reverts commit 90a8e1f.

xseth03 · 2023-06-27T13:57:48Z

I'm having the same problem with version 8.8.1 on TCP

ebeahan · 2023-06-27T15:36:31Z

@xseth03 This fix will be included in 8.8.2

efd6 · 2023-07-23T08:49:35Z

@mussi can you provide the config for the udp listener that you have configured?

mussi · 2023-07-26T13:33:02Z

i create in inputs.d a file with :

- type: syslog
  format: auto
  protocol.udp:
    host: "0.0.0.0:514"
  timezone: "UTC"
  processors:
    - add_locale: ~
  fields_under_root: true
  fields:
    dtp.ambiente: "dev"
    dtp.categoria: "syslogpadrao"
    dtp.type: "syslog"

- type: syslog
  format: auto
  protocol.tcp:
    host: "0.0.0.0:514"
  timezone: "UTC"
  processors:
    - add_locale: ~
  fields_under_root: true
  fields:
    dtp.ambiente: "dev"
    dtp.sistema: "syslogpadrao"
    dtp.type: "syslog"

it's one of... i have 26 listen ports

my output is for redis.

efd6 · 2023-07-26T21:35:34Z

@mussi Thanks. I should have said TCP, but you have provided that. The port in that configuration does not agree with the set of addresses in the logs, all the check are for ports 5999, 10303, 10304, 10309, 10312 and 10315, but your config is specifying 514.

What do you get if you grep ':0202' /proc/net/tcp6 on your host? Do you have other configurations where the ports above are specified?
