* build: consistently include config.h unconditionallyDmitry V. Levin2024-08-281-2/+0
| | | | | | | | Given that in most places config.h is included unconditionally, there is no point in keeping remaining HAVE_CONFIG_H checks. Public header files do not use config.h and therefore are not affected by this change anyway.
* pam_echo: handle short readsTobias Stoeckmann2023-12-041-2/+2
| | | | | | | | | | | | | | If the file parsed by pam_echo is larger than INT_MAX, then it is possible that uninitialized memory is printed on screen. The return value of pam_modutil_read is not negative if the size argument (casted to an int) is negative. Instead 0 is returned. This can also happen with any other file if a short read is triggered. Check if file is fully parsed or not. Signed-off-by: Tobias Stoeckmann <tobias@stoeckmann.org>
* pam_echo: avoid heap overflow on huge filesTobias Stoeckmann2023-11-131-0/+7
| | | | | | | The module might overflow heap on 32 bit systems if a 4 GB file is supplied as argument. Signed-off-by: Tobias Stoeckmann <tobias@stoeckmann.org>
* modules: remove PAM_SM_* macrosDmitry V. Levin2020-05-031-5/+0
| | | | | | Starting with commit a684595c0bbd88df71285f43fb27630e3829121e aka Linux-PAM-1.3.0~14 (Remove "--enable-static-modules" option and support from Linux-PAM), PAM_SM_* macros have no effect.
* modules/pam_echo: use pam_str_skip_prefixDmitry V. Levin2020-03-191-2/+4
| | | | | * modules/pam_echo/pam_echo.c: Include "pam_inline.h". (pam_echo): Use pam_str_skip_prefix instead of ugly strncmp invocations.
* Unification and cleanup of syslog log levels.Tomas Mraz2016-06-301-1/+1
