Subject: [PATCH 80/89] Fix for "net -n" option to properly deal with an
|
|
invalid argument
|
|
|
|
The help/man page of the "net" command suggests that "-n" option can
|
|
accept two kinds of argument: PID or task_struct pointer. However,
|
|
the "net -n" command accepts an invalid argument and shows the
|
|
namespace of the current context silently. For example:
|
|
|
|
crash> net -n 1000000000
|
|
NET_DEVICE NAME IP ADDRESS(ES)
|
|
ffff949dc11d7000 lo 127.0.0.1
|
|
ffff949dcc01c000 eno49 192.168.122.17
|
|
|
|
With the patch, emit an error expectedly.
|
|
|
|
crash> net -n 1000000000
|
|
net: invalid task or pid value: 1000000000
