Relevant BUGIDs:
Purpose of commit: new feature Commit summary: --------------- 2009-02-27 Tomas Mraz <> * modules/pam_mkhomedir/pam_mkhomedir.c(create_homedir): Replace signal() with sigaction(). * modules/pam_namespace/pam_namespace.c(inst_init, cleanup_tmpdirs): Likewise. * modules/pam_unix/pam_unix_acct.c(_unix_run_verify_binary): Likewise. * modules/pam_unix/pam_unix_passwd.c(_unix_run_update_binary): Likewise. * modules/pam_unix/passverify.c(su_sighandler): Likewise. * modules/pam_unix/support.c(_unix_run_helper_binary): Likewise. * modules/pam_tally2/ Link the pam_tally2 app to libpam for auxiliary functions. * modules/pam_tally2/pam_tally2.8.xml: Drop non-existing no_reset option. Document new serialize option. * modules/pam_tally2/pam_tally2.c: Add support for the new serialize option. (_cleanup, tally_set_data, tally_get_data): Add tally file handle to tally PAM data. Needed for fcntl() locking. (get_tally): Use low level file access instead of stdio buffered FILE. If serialize option is used lock the tally file access. (set_tally, tally_bump, tally_reset): Use low level file access instead of stdio buffered FILE. Close the file handle only when it is not owned by PAM data. (pam_sm_authenticate, pam_sm_setcred, pam_sm_acct_mgmt): Pass the tally file handle to tally_set_data(). Get it from tally_get_data(). (main): Use low level file access instead of stdio buffered FILE.

+ Serialize access to the tally file using locks. This option might
+ be used only for non-multithreaded services because it depends on
+ the fcntl locking of the tally file. Also it is a good idea to use
+ this option only in such configurations where the time between auth
+ phase and account or setcred phase is not dependent on the
+ authenticating client. Otherwise the authenticating client will be
+ able to prevent simultaneous authentications by the same user by
+ simply artificially prolonging the time the file record lock is held.
