The Status Engine allow the measurements of how many ModSecurity
instances are running around the world, as long as information
on how many times it had been restarted and so on. Everytime that
the server is started it perform a DNS query that is redirected
to our servers, that query constains information about the
ModSecurity version and it dependencies versions. It also sends a
unique indetification generate locally for the server, avoiding
counting the same server twice while generating the statistics.
This id is a sha-1 hash of the machine name + mac address of the
first network adapter. In this commit it is enabled by default,
in the release will be a configuration option to disable this
functionality. It also important to cite that the information
gather by this query will be also available in ModSecurity website
public open via a JSON stateless API. There will be an fancy
heatmap as well.
Continuation of kukackajiri's work to provide fixes for errors pointed by
Parfait. The function copy_rules had an integer as return code but it was not
filed proper neither checked by its callers. This commit just adds sanity
checks and documentation for the copy_rules function. Marking were placed
on the copy_rules callers, but the return code is not handled yet.
For kukackajiri's work, see merge request: #612
Before this patch, if something went wrong while loading the configuration in
memory, not in terms of syntax but other run time factors such as memory
allocation, the webserver will refuse to start and no further message was given
to the user. This patch adds "Internal Error messages" that are intend to let
the user know more information about the problem that he/she is facing.
Proxy is not yet ready for nginx. Instead of give a generic error, this patch
adds a clean message explains that such functionality is not available on the
nginx port. This patch also modifies the test cases to reflect this changes.
SecServerSignature was leading nginx to crash. It was trying to write over a
memory area that it was not allowed to. In order to fix that a new function was
created on the standalone api. This function is called
modsecIsServerSignatureAvailale. Whenever it returns data it means that the
function SecServerSignature was used by the user. Nginx module was also patched
to support this new function.
mod_extract_forwarded2.c is already present in this list, but there is a
(seemingly better) alternative for Apache 2.2 which is distributed in
Fedora EPEL that is called mod_extract_forwarded.c.
There is a function named inet_pton on windows API, with different
signature. This patch just override the windows function and point
the inet_pton to our implementation.
