📝 WalkthroughWalkthroughThe server now passes the instance user to the fapolicy template. The rules allow the JVM to open PKI JSP and template files under Changesfapolicyd JVM resource access
Estimated code review effort: 2 (Simple) | ~5 minutes Merge Risk: 🟠 High · up to The new fapolicyd rules likely will not match the JVM or nested JSP and template files, so PKI deployment can remain blocked when fapolicyd is enabled.

Full details: Title checkExplanation The title identifies the main change involving JSP and template files in fapolicy. The implementation adds templated allow rules rather than trust database entries, but the title remains sufficiently related to the pull request objective.

RHEL 10 fapolicyd-cli --file add --file update --update behavior official documentation
💡 Result:
In Red Hat Enterprise Linux (RHEL) 10, the fapolicyd-cli utility is used to manage the fapolicyd trust database [1]. The commands you mentioned are used to maintain files in the trusted list and synchronize the daemon's internal database [1][2][3]. fapolicyd-cli --file add This command adds specified files or directories to the trust database [3]. By default, it appends the path to /etc/fapolicyd/fapolicyd.trust, but you can use the --trust-file option to create or append to a specific file in /etc/fapolicyd/trust.d/ [1][4]. If you provide a directory path, it recursively adds all regular files within that directory [3]. fapolicyd-cli --file update This command refreshes the file trust database by recalculating the size and SHA-256 hash of already-listed files [3]. This is necessary if the content of a previously trusted file has changed [1][4]. If no arguments are provided, it updates every file currently in the file trust database; alternatively, you can specify a path to update only specific files or directories [3]. fapolicyd-cli --update This command notifies the running fapolicyd daemon to perform an update of its internal trust database based on the current state of the trust files [3][4]. After modifying trust entries via --file add or --file update, you must run --update for the changes to take effect in the daemon's enforcement policy [1][4]. Summary of Workflow 1. Add/Update Trusted Files: Use fapolicyd-cli --file add or --file update to manage the entries in your trust files [1][4]. 2. Synchronize Daemon: Use fapolicyd-cli --update to load those changes into the active fapolicyd memory [3][4]. Note that for files managed via the RPM database, fapolicyd typically learns about changes automatically through its DNF plugin [5]; manual commands are primarily used for files installed outside of the DNF/RPM framework [2][5].

The command is including all *.jsp and *.template file present in the /usr/share/pki folder in the trustdb during the post-install of pki-server. This is working if all the files are already present. If the initial setup does not have a subsystem and it is deployed later, does the related jsp/template files get included in the trustdb?

Moved the change to update *.jsp and *.template files to be in the trust database at deployment runtime to address the case where all subsystem packages may not be installed in the beginning. |

RHEL fapolicyd-cli --file add duplicate registration exit code --update documentation
💡 Result:
When using fapolicyd-cli with the --file add option, attempting to register a file that is already present in the trust database is treated as a no-op (no operation) [1][2][3]. According to the official fapolicyd-cli man page, such operations result in an exit code of 9 [1][2][3]. This specific exit status is defined as No-op/Not-found/Nothing to do, indicating that the operation completed without making changes because the target file was already correctly registered or otherwise not requiring an update [1][2][3]. Documentation Summary: - Command: fapolicyd-cli --file add - Behavior on Duplicate: The system recognizes the existing entry and performs no action [1][3]. - Exit Code: 9 [1][2][3]. If you are writing scripts to manage file trusts, you should handle exit code 9 as a success (or a benign state) rather than a failure, as it indicates the desired state (file being trusted) is already achieved [1][3].

site:docs.redhat.com fapolicyd-cli --file add exit code 9 duplicate trust
💡 Result:
When using the fapolicyd-cli --file add command, receiving an exit code 9 related to a duplicate trust entry indicates that you are attempting to add a file or directory to the trust database that is already present in a configured trust source [1][2]. In the fapolicyd framework, trust sources are managed via the /etc/fapolicyd/fapolicyd.trust file or files located within the /etc/fapolicyd/trust.d/ directory [1][3]. The fapolicyd-cli utility checks these locations to ensure integrity [1][4]. If the file path you are attempting to add already exists in one of these files, the command will fail with a non-zero exit code because the entry is redundant. To resolve this: 1. Verify existing trust entries: You can manually inspect the contents of /etc/fapolicyd/fapolicyd.trust and any files within /etc/fapolicyd/trust.d/ to identify where the entry already exists [1][2]. 2. Use --list: While fapolicyd-cli --list primarily shows execution rules, checking your trust configuration files is the standard method for resolving duplicate trust issues [1][4]. 3. Manage entries: If you need to change the trust parameters for an existing file, you must first remove or modify the existing entry in the appropriate trust file before adding it again [1][2]. If you are attempting to refresh the database after modifying these files, ensure you use the correct commands: use fapolicyd-cli --file update to refresh specific files or the entire database, and then run fapolicyd-cli --update to apply the changes to the running service [1][5][6].

fapolicyd-cli source exit code 9 file add already exists trust database
💡 Result:
When you run fapolicyd-cli with the add command and receive exit code 9, it indicates that the operation was a "No-op," "Not-found," or "Nothing to do" [1][2]. Specifically, this exit code is returned when the command completes without making any changes to the system [1][3]. In the context of adding a file to the trust database, receiving exit code 9 means that the file was not added because it is already present in the trust database [1][2]. The utility recognized that no action was required, as the file was already accounted for, and therefore exited with a status indicating no changes were performed [1][3]. If you intend to update the entry for a file that already exists—for example, if the file's size or hash has changed—you should use the update command instead [1][4]: sudo fapolicyd-cli --file update <path_to_file> Always remember to refresh the trust database after making manual changes to ensure the daemon registers the updates [5][6].

💡 Result:
When using fapolicyd-cli with the --file add option, providing a nonexistent file path results in an exit code of 8 [1]. According to the fapolicyd-cli documentation regarding exit codes, a status of 8 indicates a "Filesystem/I-O/permission error," which covers scenarios such as failing to stat or access the specified file [1]. An exit code of 9 is reserved for "No-op/Not-found/Nothing to do" operations, which typically applies when an operation completes without making changes, rather than when the input path itself is invalid [1].

Fail the installation when trust registration fails.
Check each command result and report errors before restarting fapolicyd. Do not discard stderr. Treat status 9 as the documented no-op status; an unconditional subprocess.check_call() would fail on duplicate registrations during another subsystem installation.

The approach has a problem. It is invoked only during deployment of an instance. If there is an update which modify a jsp or template file then it will be blocked because the hash does not match.
Additionally, it keep adding file at every deployment but if the file has been added it will report an error and the associated information are not updated. The command to use should be update if the file is already present.
IMHO the file update should be in the spec file but splitted among the rpm including the file.
An easier, and more manageable alternative, would be to add some rules into the file base/server/etc/fapolicy.rules which allow the file. Something like:
allow perm=open uid=pkiuser exe=/usr/bin/java : path=glob:/usr/share/pki/**/*.jsp
allow perm=open uid=pkiuser exe=/usr/bin/java : path=glob:/usr/share/pki/**/*.template
These can be template so the correct user/exec can be provided during the deployment.

Before restart the fagenrules --load command should be invoked with newer fapolicyd version.
I will look into this approach. Thank you |
On RHEL 10, libmagic classifies JSP files as "JavaScript source" instead of "HTML document" (as on RHEL 8). This puts them in fapolicyd's %languages group, and since the RPM trust backend does not include .jsp files, they are denied by the default fapolicyd ruleset. This causes pkispawn to fail with a JSP compilation error when fapolicyd is enabled. The fix adds glob-based fapolicy rules to the rules template that allow the JVM process running as the PKI user to open JSP and template files under /usr/share/pki/. This is path-based rather than hash-based, so RPM updates do not require re-registering files in the trust database. Assisted by Claude Opus 4.6

fapolicyd rules man page exe dir path glob recursive ** semantics v1.4.3
💡 Result:
In fapolicyd (version 1.4.3 and generally), the rule syntax for path matching distinguishes between exact matching, literal directory prefix matching, and glob pattern matching [1][2]. The following semantics apply regarding your query: Globbing Semantics: - Globbing is explicitly supported for the subject 'exe' and object 'path' attributes only [1][2]. - To trigger glob matching, you must prefix the value with the 'glob:' keyword (e.g., path=glob:/path/to/) [1][2]. - The pattern follows fnmatch(3) syntax [1][2]. - A '' matches zero or more characters, but wildcards do not match a slash ('/') [1][2]. Consequently, each path component must be written explicitly [1][2]. - Recursive '' (globstar) matching is not supported [1][2]. Dir Semantics: - The 'dir' attribute acts as a literal directory prefix [1][2]. - It is intended for matching a complete subtree rooted at a fixed directory [1][2]. - 'dir' does not support the 'glob:' prefix [1][2]. If you use 'glob:' with 'dir', it is considered a rule error [1][2]. - If you need to match a directory specifically, it is recommended to end the path with a trailing slash ('/') [2][3]. In summary, 'dir' provides a non-recursive, literal-prefix mechanism, while 'glob:' provides pattern matching on the 'exe' and 'path' attributes without support for recursive directory traversal (globstars) [1][2].

Use supported fapolicyd matchers for both rules.
exe=/usr/lib/jvm/ matches an executable path, not the JVM directory. Also, path=glob: uses fnmatch(3) semantics: * does not cross /, and recursive ** matching is unsupported. Use dir=/usr/lib/jvm/ and explicit path patterns for each supported directory depth.

RHEL 10.2 fapolicyd 1.4.3 rule manual path=glob recursive ** exe directory matching
💡 Result:
In fapolicyd, including version 1.4.3 as found in RHEL 10, directory matching and path matching have specific syntax rules [1][2]. Recursive Directory Matching To make a directory rule effective recursively, you must add a trailing slash to the value of the dir= parameter [1]. For example, dir=/tmp/ will apply to all files and subdirectories within /tmp/ [1]. This is a standard practice for ensuring a rule covers the entire directory tree under the specified path [1][3][4]. Globbing and Path Matching The path= attribute supports globbing when prefixed with glob: [2][5]. For example: path=glob:/opt/vendor/product-*/bin/tool [2][5]. * Syntax: The glob pattern uses fnmatch(3) syntax, where * matches zero or more characters and ? matches a single character [2]. * Recursive (Globstar): Recursive `` globstar matching is not supported in fapolicyd [2][5]. You must define patterns explicitly for the directory structure [2]. * Behavior: A wildcard does not match a slash, which means each variable path component must be explicitly written in the pattern [2]. Executable (exe) Matching The exe= attribute defines the subject executable [6]. * Globbing: Historically, `exe=` did not support globbing, and in current versions, it remains primarily designed for exact path matching [3][4]. If you need to match multiple executables within a directory structure, the recommended approach is to use `dir=` for directory-level matching or, where supported, multiple `exe=` rules [3][7]. * Directory-based `exe` matching: If you wish to match based on the directory where an executable resides, use the `exe_dir` attribute (or simply `dir` if configuring objects) [3][4]. Important Configuration Notes * Rules are compiled: Changes to individual rule files in `/etc/fapolicyd/rules.d/` require the `fagenrules` script to merge them into `/etc/fapolicyd/compiled.rules` before they take effect [1][8]. * Performance: Prefer exact paths or `dir=` matching over `glob:` patterns whenever possible, as glob evaluation is more computationally expensive [2]. * Security: When using `glob:` or `dir=` on user-writable locations, it is strongly recommended to require `trust=1` or use file hash constraints to prevent unauthorized execution [2][5].

site:docs.redhat.com RHEL 10 fapolicyd.rules exe= executable path directory path=glob fnmatch 1.4.3
💡 Result:
In Red Hat Enterprise Linux (RHEL) 10, the fapolicyd framework uses rules defined in the /etc/fapolicyd/rules.d/ directory [1]. These rules are managed via the fagenrules script, which compiles them into a single /etc/fapolicyd/compiled.rules file [1]. The syntax for these rules supports specific decision parameters, including exe= and path=. The path= parameter supports globbing patterns to match file paths [1]. While fnmatch is the underlying C library function used by fapolicyd to process these glob patterns, specific versioning (such as "1.4.3") is not typically exposed or required in the rule syntax itself. Key rule parameters for path matching include: 1. path=: Matches specific files. For example, path=/tmp/ls matches the file /tmp/ls [1]. 2. dir=: Matches files within a directory. If a trailing slash is provided (e.g., dir=/tmp/), the rule applies recursively to all files within that directory [1]. 3. exe=: Used to match the executable that is initiating the action (the process attempting to execute the target file). This is often used in combination with other parameters to restrict which applications can launch others [1]. For detailed information on the rule syntax, you should refer to the fapolicyd.rules(5) manual page installed on your RHEL 10 system [1]. If you are creating custom policies, it is recommended to add your rules to a new file within /etc/fapolicyd/rules.d/ (e.g., 80-myapps.rules) and run fagenrules --check and fagenrules --load to apply changes [1][2].

fapolicyd.rules 1.4.3 man page exe= exact path exe_dir directory matching
💡 Result:
In the fapolicyd.rules(5) manual, exe and exe_dir function as follows: exe (Subject Attribute) This attribute specifies the full, exact path to an executable [1][2]. By default, fapolicyd does not support globbing for exe [3][1]; however, some newer versions may support an explicit glob: prefix to enable pattern matching for this attribute [4]. It also supports the special keyword untrusted, which matches subjects not listed in the RPM database [1][2]. exe_dir (Subject Attribute) This attribute matches an executable based on its directory path [1][2]. When using exe_dir, you provide the full path to a directory [1]. It is recommended to end the path with a forward slash (/) to explicitly indicate that the value represents a directory [5][1]. exe_dir supports three specific keywords as alternatives to literal directory paths: execdirs, systemdirs, and untrusted [1][2]. Key Distinctions - Exact vs. Directory Matching: exe requires the full path to a specific file [1][2], whereas exe_dir matches files located within a specified directory or directory hierarchy [1][4]. - Path Trailing Slash: For exe_dir, adding a trailing slash (/) is standard practice and recommended to ensure the system correctly interprets the value as a directory [5][1]. - Keywords: exe only supports the untrusted keyword [1][2]. exe_dir supports execdirs (which typically includes /usr, /bin, /sbin, /lib, /lib64, and /usr/libexec), systemdirs (which includes execdirs plus /etc), and untrusted [1][2][6]. Note: While older documentation or manual pages emphasize exact matching, always check the specific version of fapolicyd installed on your system, as capabilities like globbing support (via the glob: prefix) have been introduced in later releases [4].

Use exe_dir and replace the recursive path glob.
exe= requires an exact executable path, so exe=/usr/lib/jvm/ does not match JVM executables. Use exe_dir=/usr/lib/jvm/.
path=glob: is supported, but ** does not match /. Use explicit patterns, or use dir=/usr/share/pki/ if the complete subtree is intended.

On RHEL 10, libmagic classifies JSP files as "JavaScript source" instead of "HTML document" like in RHEL 8. This puts them in fapolicyd's %languages group, and since the RPM trust backend does not include .jsp files, they are denied by the default fapolicyd ruleset. This causes pkispawn to fail with a JSP compilation error when fapolicyd is enabled.
The fix adds JSP and template files to the fapolicy file trust backend during RPM post-install.
This fix is for DOGTAG-4549, DOGTAG-4548 and DOGTAG-4547
