Subject: [PATCH] Don't allow unhandled POSTs to write to the filesystem by
|
|
default
|
|
|
|
If there's no registered handler for a POST request, the default behaviour
|
|
is to write it to the filesystem. Several million deployed devices appear
|
|
to have this behaviour, making it possible to (at least) store arbitrary
|
|
data on them. Add a configure option that enables this behaviour, and change
|
|
the default to just drop POSTs that aren't directly handled.
