Support specification of allowed tags/attributes/protocols via global package parameters.

This change makes it possible to define for a package values for

AllowedTags, AllowedAttributes, or AllowedProtocols. If (some of)

these exist, use these for configuring "ad_html_security_check". If +

not, fall back to the default (site wide) definition.

This change is fully backward compatible and effects on sites defining

such global parameters. This change was induced by the need of large

sites, where it is not feasible to set these parameters on the package

instance level, since this site has 830000 packages instances.

util::file_content_check: new utility for checking content of a file

Check whether the provided file is of the requested type.

This function is more robust and protable than relying on

external programs and their output, but it does not work on

all possible file types. It checks a few common cases that

could lead to problems otherwise, like when uploading archives.

Extended LockfreeCache:

- Feneralized flag "-no_empty" of "LockfreeCache eval" to "-no_cache LIST"

The provided list can contain multiple values that should not be cached.

- The new parameter "-from_cache_indicator" can be used to return information

whether the returned value was returned from the cache or not.

added support for "ns_trim -prefix".

The command is predefined in NaviServer; if not available, a comatibility version is added.

This change also mitigates a potential memory-leak problem in nsv_dict with certain

versions of NaviServer which might lead on busy sites to problems.

Stronger password hashes for OpenACS

This change introduces the possibility to use either the classical

OpenACS password hash algorithm "salted-sha1" or the SCRAM passord

function "scram-sha-256". The latter can be used by (a) using the

most recent version of NaviServer (from Sept 28, 2021 or newer) and

(b) by configuring the password hash preferences via Kernel package

parameter "PasswordHashAlgorithm". The package parameter can contain a

list of multiple hash algorithms in preference order. The most

preferred available algorithm is chosen.

By default, the "PasswordHashAlgorithm" is "salted-sha1", and the

behavior is as before. After upgrading to the new version of acs-tcl

and acs-kernel, the preference list can be configured. When a user

logs in and the preferred available algorithm is different from the

previously used algorithm, the upgrade is performed for the user

automatically.

The usage of SHA1 in OpenACS is easily target of security audits (see

[1]). The biggest danger is that if somebody gets full access to the

"users" table (e.g. when decommissioning a hard disk). In this case

the hashes can be attacked with dictionaries by using some crypto

hardware (when someone gets raw access to the DB, one has usually some

other big problems). However, by using the "scram-sha-256" hash

function this danger is substantially reduced. This function computes

a password hash using PBKDF2 (Password-Based Key Derivation Function

2). This function is used to reduce vulnerabilities of brute-force

attacks against password hashes. The hash function of SCRAM is PBKDF2

[RFC2898] with HMAC as the pseudorandom function (PRF) and with dkLen

== output length of HMAC == output length of the digest function. So,

it uses a better hash algorithm (sha-256 vs. sha1) and applies this a

high number of times (15K times for a password hash computation).

NaviServer supports as well the even better SCRYPT algorithm, but this

is only available when NaviServer is compiled with OpenSSL 3.0 or

newer. On the contrary, scram-sha-256 (actually PKCS5_PBKDF2_HMAC) is

available since OpenSSL 1.0.0 (2015).

All the improved hash functions require NaviServer with its tight

integration to the crypto functions of OpenSSL.

Added page_contract filter "object_id"

This change adds the page_contract filter "object_id", which validates

values whether these are syntactically acceptable as object_ids in

PostgreSQL and Oracle.

Note that before one is able to use the filter, the server has to be

restarted. Otherwise, when e.g. "apm/version_reload.tcl" would be

executed with the new filter, it would fail. So, one has to be careful

on update scripts, when people upgrade from old version not to create

a blocking mutual blocking condition.

Added support for trailing non-positional arguments

The change makes the old hack with the own trailing-argument-parser

"ad_arg_parser" obsolete by using directly the c-level argument parser

which is anyhow capable of handling trailing arguments. A few changes

were necessary for api doc to handle there trailing arguments as well.

The proc "db_string" is already converted to use native arguments.

Fix for issue #3442 to support range types in .xql files

PostgreSQL supports range types since 9.5. When using range types,

square braces have to be used in SQL statements. Since OpenACS uses

always Tcl substitution in .xql files, and OpenACS does NOT allow

backslash substitution in these files, square brackets could not be

escaped and therefore not be used in .xql files so far. This change

allows now a developer to deactivate the substitution by passing

e.g. "-subst none" to the db_* command using the .xql file. Valid

values for "-subst" are "all", "none", "vars", and "commands", default

is "all" which is exactly the behavior of before. Therefore, this

change is fully backward compatible.

added "ad_conn bot_p" to check, whether request was initiated by a bot

This feature is based on a simple heuristic based on the user-agent

(which can be certainly extended). It is useful to avoid e.g. Google

bot to run into "notifications subscribe" + login attempts, which

are useful for not-logged-in user, but not for bots. These attemps

lead to failures in google statistics that might reduce the google

ranking of a web site.
