07a804caf3 Quiet sign comparision warnings. 2013-10-23 15:03:31 -06:00
Todd C. Miller
69ab48f16d Don't allow the debug subsystem to be initialized twice. 
Otherwise we can exhuast our stack when built in static mode.

79acd5db49 Simple event subsystem that uses poll() or select(). Basically a 
simplied subset of libevent2.  Currently only fd events are supported
(since that's all we need).  The poll() backend is used by default,
except on Mac OS X where poll() is broken for devices (including
/dev/tty and ptys).

99352d6738 Rename error.h -> fatal.h now that there is no error() function. 2013-08-15 14:24:29 -06:00

bec394dc11 Add support to the debug subsystem for zero-length strings. This 
can happen for things like warning(NULL) or fatal(NULL) where we
just want to log the errno string.

95b50f84af Use time(&now) instead of now = time(NULL) when storing the current 
time in a time_t (better compiler error checking).
Better parsing and printing of 64-bit time_t on 32-bit platforms.

1e0a7d5112 Fix debug logging from the plugin when there is no error number. 
This was broken in the big debugging reorg for 1.8.7.

1d7072fe09 Don't include <sys/param.h>. We only needed it for MAXPATHLEN, 
MAXHOSTNAMELEN and the MIN/MAX macros.  We now use PATH_MAX and
HOST_NAME_MAX throughout without falling back on MAXPATHLEN or
MAXHOSTNAMELEN and define our own MIN/MAX macros as needed.

c2c6616a0c Move _sudo_printf from src/conversation.c to common/sudo_printf.c. 
Add sudo_printf function pointer that is initialized to _sudo_printf()
instead of requiring a sudo_conv function pointer everywhere.  The
plugin will reset sudo_printf to point to the version passed in via
the plugin open function.  Now plugin_error.c can just call sudo_printf
in all cases.  The sudoers binaries no longer need their own version
of sudo_printf.

0178d5ae01 Set group on sudo_debug when creating it to gid 0 so systems without 
BSD group semantics don't get the invoking user's group.

f8660f9988 Add variants of warn/error and sudo_debug_printf that take a va_list 
instead of a variable number of args.

d89b1a6be2 Support for using SSSD (http://fedorahosted.org/sssd/) as a sudoers 
data source.  From Daniel Kopecek and Pavel Brezina.

c8ce3a0a85 Log the process id in the debug file output. Since we don't want 
to keep calling getpid(), stash the value at init time and when we
fork().

abdff25703 Always pass __func__, __FILE__ and __LINE__ in sudo_debug_printf() 
and use a new flag, SUDO_DEBUG_FILENO to specify when to use it.
This allows consumers of sudo_debug_printf() to log that data without
having to specify it manually.

2c84bd4d08 Log warning() at SUDO_DEBUG_WARN not SUDO_DEBUG_ERROR. 
Log the function, file and line number in the debug log for warning()
and error().

2fe41248ac Add SUDO_DEBUG_ERRNO flag to debug functions so we can log errno. 
Use this flag when wrapping error() and warning() so the debug
output includes the error string.

aecb5206e2 Fix compiler warnings on some platforms and provide a better method 
of defeating gcc's warn_unused_result attribute.

37770ecf1e Initial cut at a hooks implementation. The plugin can register 
hooks for getenv, putenv, setenv and unsetenv.  This makes it
possible for the plugin to trap changes to the environment made by
authentication methods such as PAM or BSD auth so that such changes
are reflected in the environment passed back to sudo for execve().

c91f5ee680 Make sure we don't try to fall back to using the conversation 
function for debugging in the main sudo process if we are unable
to open the debug file.

a64f1eaea8 Do not close error pipe or debug fd via closefrom() as we need them 
to report an exec error should one occur.
