0123cf63f1 The Path setting for the plugin directory is "plugin_dir" not "plugin". 2015-12-18 14:03:59 -07:00
Todd C. Miller
55531958de Allow sudo.conf Path settings to disable path names (by setting the 
value of NULL).

a2979ed809 Remove checks for __sys_siglist and __sys_signame. They are internal 
to libc and there are no known systems that export those symbols
that do not already export the single underbar or no-underbar versions.

67183d74f4 Remove include/compat/timespec.h. Systems old enough to lack struct 
timespec are too old to build a modern sudo.

448b18de2b Set errno to EINVAL if sudo_lock_* is called with a bad type. 2015-09-07 06:06:08 -06:00

0c70df5de9 Implement suspend/resume callbacks for the conversation function. 
If suspended, close the timestamp file (dropping all locks).  On
resume, lock the record before reading the password.

For this to work properly we need to be able to run th callback
when tsetattr() suspends us, not just when the user does.  To
accomplish this the term_* functions now return EINTR if SIGTTOU
would be generated.  The caller now has to restart the term_*
function (and send itself SIGTTOU) instead of it being done
automatically.

00142c91fa Lock individual records in the timestamp file instead of the entire 
file.  This will make it possible for multiple sudo processes using
the same tty to serialize their timestamp lookups.

98a15d9879 Add a struct sudo_conv_callback that contains on_suspend and on_resume 
function pointer args plus a closure pointer and at it to the
conversation function.

explicit call to sudo_warnx().

d77941c2be We require POSIX so no need to conditionally include dirent.h. 
Add a check for d_namlen and use the result in the NAMLEN macro.

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

54f9de6cce Add an error flag to the lbuf struct to simplify error checking. 
Callers of the lbuf functions now check the error flag to tell if
a memory allocation error ocurred.

d36e46cb6e Must call round_nfds() with fd+1 since it takes a count not the fd 
number.  In other words, the lowest value is 1, not 0.

9884df8c9e If asprintf() or vasprintf() fail, set the dest pointer to NULL 
like BSD and Solaris do.  This appears to be the direction glibc
is going as well.
