August 2010 + + + This manual documents what a programmer needs to know in order + to write a module that conforms to the + Linux-PAM standard.It also + discusses some security issues from the point of view of the + module programmer. + + + + + + Introduction +
+ Description + + Linux-PAM (Pluggable Authentication + Modules for Linux) is a library that enables the local system + administrator to choose how individual applications authenticate + users. For an overview of the + Linux-PAM library see the + Linux-PAM System Administrators' Guide. + + + A Linux-PAM module is a single + executable binary file that can be loaded by the + Linux-PAM interface library. + This PAM library is configured locally with a system file, + /etc/pam.conf, to authenticate a user + request via the locally available authentication modules. The + modules themselves will usually be located in the directory + /lib/security (or + /lib64/security, depending on the architecture) + and take the form of dynamically loadable object files (see + + dlopen3 + . Alternatively, the modules can be statically + linked into the Linux-PAM library; + this is mostly to allow Linux-PAM to + be used on platforms without dynamic linking available, but this is + a deprecated functionality. It is the + Linux-PAM interface that is called + by an application and it is the responsibility of the library to + locate, load and call the appropriate functions in a + Linux-PAM-module. + + + Except for the immediate purpose of interacting with the user + (entering a password etc..) the module should never call the + application directly. This exception requires a "conversation + mechanism" which is documented below. + +
+ +
+ Synopsis + +#include <security/pam_modules.h> + +gcc -fPIC -c pam_module.c +gcc -shared -o pam_module.so pam_module.o -lpam + +
+ + + + What can be expected by the module + + Here we list the interface that the conventions that all + Linux-PAM modules must adhere to. + +
+ + Getting and setting <emphasis>PAM_ITEM</emphasis>s and + <emphasis>data</emphasis> + + + First, we cover what the module should expect from the + Linux-PAM library and a + Linux-PAM aware application. + Essentially this is the libpam.* library. + + + + + + + + + + +
+
+ + Other functions provided by <filename>libpam</filename> + + + +
+ + + + What is expected of a module + + The module must supply a sub-set of the six functions listed + below. Together they define the function of a + Linux-PAM module. Module developers + are strongly urged to read the comments on security that follow + this list. + +
+ Overview + + The six module functions are grouped into four independent + management groups. These groups are as follows: + authentication, account, + session and password. + To be properly defined, a module must define all functions within + at least one of these groups. A single module may contain the + necessary functions for all four groups. + +
+ Functional independence + + The independence of the four groups of service a module can + offer means that the module should allow for the possibility + that any one of these four services may legitimately be called + in any order. Thus, the module writer should consider the + appropriateness of performing a service without the prior + success of some other part of the module. + + + As an informative example, consider the possibility that an + application applies to change a user's authentication token, + without having first requested that + Linux-PAM authenticate the + user. In some cases this may be deemed appropriate: when + root wants to change the authentication + token of some lesser user. In other cases it may not be + appropriate: when joe maliciously wants + to reset alice's password; or when anyone + other than the user themself wishes to reset their + KERBEROS authentication token. A policy + for this action should be defined by any reasonable + authentication scheme, the module writer should consider + this when implementing a given module. + +
+
+ Minimizing administration problems + + To avoid system administration problems and the poor + construction of a /etc/pam.conf file, + the module developer may define all six of the following + functions. For those functions that would not be called, + the module should return PAM_SERVICE_ERR + and write an appropriate message to the system log. When + this action is deemed inappropriate, the function would + simply return PAM_IGNORE. + +
+
+ Arguments supplied to the module + + The flags argument of each of + the following functions can be logically OR'd with + PAM_SILENT, which is used to inform the + module to not pass any text (errors or + warnings) application. + + + The argc and argv + arguments are taken from the line appropriate to this + module---that is, with the service_name + matching that of the application---in the configuration file + (see the Linux-PAM + System Administrators' Guide). Together these two parameters + provide the number of arguments and an array of pointers to + the individual argument tokens. This will be familiar to C + programmers as the ubiquitous method of passing command arguments + to the function main(). Note, however, that + the first argument (argv[0]) is a true + argument and not the name of the module. + +
+
+
+ Authentication management + + +
+
+ Account management + +
+
+ Session management + + +
+
+ Authentication token management + +
+ + + + Generic optional arguments + + Here we list the generic arguments that all modules can expect to + be passed. They are not mandatory, and their absence should be + accepted without comment by the module. + + + + debug + + + Use the + pam_syslog3 + call to log debugging information to the system + log files. + + + + + use_first_pass + + + The module should not prompt the user for a password. + Instead, it should obtain the previously typed password + (by a call to pam_get_item() for the + PAM_AUTHTOK item), and use that. If + that doesn't work, then the user will not be authenticated. + (This option is intended for auth and + passwd modules only). + + + + + + + + Programming notes + + Here we collect some pointers for the module writer to bear in mind + when writing/developing a Linux-PAM + compatible module. + + +
+ Security issues for module creation +
+ Sufficient resources + + Care should be taken to ensure that the proper execution + of a module is not compromised by a lack of system resources. + If a module is unable to open sufficient files to perform its + task, it should fail gracefully, or request additional resources. + Specifically, the quantities manipulated by the + setrlimit2 + family of commands should be taken into + consideration. + +
+
+ Who´s who? + + Generally, the module may wish to establish the identity of + the user requesting a service. This may not be the same as + the username returned by pam_get_user(). + Indeed, that is only going to be the name of the user under + whose identity the service will be given. This is not + necessarily the user that requests the service. + + + In other words, user X runs a program that is setuid-Y, it + grants the user to have the permissions of Z. A specific example + of this sort of service request is the su + program: user joe executes + su to become the user jane. + In this situation X=joe, Y=root + and Z=jane. Clearly, it is important that + the module does not confuse these different users and grant an + inappropriate level of privilege. + + + The following is the convention to be adhered to when juggling + user-identities. + + + + + X, the identity of the user invoking the service request. + This is the user identifier; returned by the function + + getuid2 + . + + + + + Y, the privileged identity of the application used to + grant the requested service. This is the + effective user identifier; + returned by the function + geteuid2 + . + + + + + Z, the user under whose identity the service will be granted. + This is the username returned by + pam_get_user() and also stored in the + Linux-PAM item, + PAM_USER. + + + + + Linux-PAM has a place for + an additional user identity that a module may care to make + use of. This is the PAM_RUSER item. + Generally, network sensitive modules/applications may wish + to set/read this item to establish the identity of the user + requesting a service from a remote location. + + + + + Note, if a module wishes to modify the identity of either the + uid or euid of the + running process, it should take care to restore the original + values prior to returning control to the + Linux-PAM library. + +
+
+ Using the conversation function + + Prior to calling the conversation function, the module should + reset the contents of the pointer that will return the applications + response. This is a good idea since the application may fail + to fill the pointer and the module should be in a position to + notice! + + + The module should be prepared for a failure from the + conversation. The generic error would be + PAM_CONV_ERR, but anything other than + PAM_SUCCESS should be treated as + indicating failure. + +
+
+ Authentication tokens + + To ensure that the authentication tokens are not left lying + around the items, PAM_AUTHTOK and + PAM_OLDAUTHTOK, are not available to + the application: they are defined in + <security/pam_modules.h>. This + is ostensibly for security reasons, but a maliciously + programmed application will always have access to all memory + of the process, so it is only superficially enforced. As a + general rule the module should overwrite authentication tokens + as soon as they are no longer needed. Especially before + free()'ing them. The + Linux-PAM library is + required to do this when either of these authentication + token items are (re)set. + + + Not to dwell too little on this concern; should the module + store the authentication tokens either as (automatic) function + variables or using pam_[gs]et_data() the + associated memory should be over-written explicitly before it + is released. In the case of the latter storage mechanism, the + associated cleanup() function should + explicitly overwrite the *data before + free()'ing it: for example, + +/* + * An example cleanup() function for releasing memory that was used to + * store a password. + */ + +int cleanup(pam_handle_t *pamh, void *data, int error_status) +{ + char *xx; + + if ((xx = data)) { + while (*xx) + *xx++ = '\0'; + free(data); + } + return PAM_SUCCESS; +} + + +
+
+
+ Use of <citerefentry> + <refentrytitle>syslog</refentrytitle><manvolnum>3</manvolnum> + </citerefentry> + + Only rarely should error information be directed to the user. + Usually, this is to be limited to + sorry you cannot login now + type messages. Information concerning errors in the configuration + file, /etc/pam.conf, or due to some system + failure encountered by the module, should be written to + + syslog3 + with facility-type + LOG_AUTHPRIV. + + + With a few exceptions, the level of logging is, at the discretion + of the module developer. Here is the recommended usage of different + logging levels: + + + + + As a general rule, errors encountered by a module should be + logged at the LOG_ERR level. However, + information regarding an unrecognized argument, passed to a + module from an entry in the /etc/pam.conf + file, is required to be logged at the + LOG_ERR level. + + + + + Debugging information, as activated by the + debug argument to the module in + /etc/pam.conf, should be logged + at the LOG_DEBUG level. + + + + + If a module discovers that its personal configuration + file or some system file it uses for information is + corrupted or somehow unusable, it should indicate this + by logging messages at level, LOG_ALERT. + + + + + Shortages of system resources, such as a failure to + manipulate a file or malloc() failures + should be logged at level LOG_CRIT. + + + + + Authentication failures, associated with an incorrectly + typed password should be logged at level, + LOG_NOTICE. + + + +
+
+ Modules that require system libraries + + Writing a module is much like writing an application. You + have to provide the "conventional hooks" for it to work + correctly, like pam_sm_authenticate() + etc., which would correspond to the main() + function in a normal function. + + + Typically, the author may want to link against some standard system + libraries. As when one compiles a normal program, this can be + done for modules too: you simply append the + -lXXX arguments + for the desired libraries when you create the shared module object. + To make sure a module is linked to the + libwhatever.so library + when it is dlopen()ed, try: + +% gcc -shared -o pam_module.so pam_module.o -lwhatever + + +
