3354d27a17 Do not follow symbolic links in sudoedit by default. This behavior
can be controlled by the sudoedit_follow Defaults flag as well as
the FOLLOW/NOFOLLOW tags.

explicit call to sudo_warnx().

0b241088b3 There's no need to conditionalize the #include <unistd.h>, we require

cb63ca701c Avoid using exiting allocators in the front end. 2015-06-17 17:00:54 -06:00
Todd C. Miller
25917e435c We need to unlimit RLIMIT_NPROC in sudoers as well as the sudo front
end since set_perms() and restore_perms change the read uid and may
fail with EAGAIN on Linux kernels prior to 3.1.

4131449ffb Add a few missing sudo_new_key_val() return value checks.
Also use non-exiting allocators for consistency.

caf5d45e0f Previously, debug_return_bool was the same as debug_return_int
except that it logged true/false for 1/0.  However, this appears
to trigger a bug in some compilers.  To avoid this, debug_return_bool
now uses bool, not int.  Callers that were passing it an int have
been converted to use debug_return_int instead.

6f8af4d26d Split variable declaration out of debug_decl into debug_decl_vars()
so we can use it in main() when we know sudo_debug_enter() cannot
succeed.

be8dbeb22e Avoid using HOST_NAME_MAX directly and use sysconf(_SC_HOST_NAME_MAX)
instead.
2015-02-19 20:28:02 -07:00
Todd C. Miller
96eddddc12 Almost no systems actually define OPEN_MAX since it is dynamic on
modern OSes.  If sysconf(_SC_OPEN_MAX) ever fails, fall back on
_POSIX_OPEN_MAX instead.  We can assume modern systems have sysconf().
Also remove checks for strrchr() and strtoll() for which the HAVE_*
defines are no longer used.

59ab26dbcc Go back to a 2 args debug_decl and just use the "default" instance,
now renamed "active".

6b1b734ffa Add a flag argument to sudo_conf_read() so we can decide which
bits get parsed.  This lets us parse Debug statements first and
init the debug subsystem early.

4bf641df69 In the plugin registers with the debug framework at open time, the
sudo front-end will now set the default debug instance appropriately
before calling into the plugin.  This means the plugin no longer needs
to do the sudo_debug_set_default_instance() dance.

866cfc4fc3 Add support for multiple Debug lines per program. Callers may
register arbitrary debug facilities or use built-in defaults.  We
now use separate Debug statements for plugins and programs.

a7e724b75d Change how sudo.conf is parsed. We now do a quick parse and then
set the values after the entire file has been parsed.  This lets
us init the debug system earlier.  Plugin-specific debug flags are
now stored in struct plugin_info and struct plugin_container and
passed to the plugin via one or more debug_flags settings.

1e0b8903f2 Return settings from parse_args as struct sudo_settings and format

plugin-specific settings to be added to the array.

bd99dcc028 Add sudo_warn_set_conversation() to specify a conversation function
to use for warn/fatal.  If no conversation function is specified,
the standard error will be used.  We now only need sudo_printf()
for things that use the parser.

7ab40be5c0 On AIX, _PATH_BSHELL is /usr/bin/bsh but we want to use /usr/bin/sh
(which is usually ksh).  This makes sudo's behavior when executing
a shell without the #! magic number match execvp() on AIX.

4f1deee575 Set runas egid to the same value as runas gid if egid not specified

db35c7c0e4 Make sudoedit work with SELinux RBAC.
Adapted from RedHat patches (Daniel Kopecek) but made to behave a
bit more like the non-SELinux bits.

12f3bdf60e Add wrapper functions for dlopen() et al so that we can support
statically compiling in the sudoers plugin but still allow other
plugins to be loaded.  The new --enable-static-sudoers configure
option will cause the sudoers plugin to be compiled statically into
the sudo binary.  This does not prevent other plugins from being
loaded as per sudo.conf.

96eb2c4f8f Add warning_gettext() wrapper function that changes to the user locale,
