Subject: [PATCH] plugins/open: Fix for interrupted select
|
|
|
|
The select syscall can be interrupted for signals like SIGPROF. The IPMI
|
|
command sent will still be outstanding but the send_command will return
|
|
an error. When the next command is sent it will get the completion for
|
|
the previous command and has the tendency to break state of end users.
