e58df973a9 Delete any pwstars we wrote after the user hits return. That way 
there is no record on screen as to the user's password length.

38c225af03 Add pwstars sudoers option that causes sudo to print a star every 
time the user presses a key.

b18eede622 Even if neither stdin nor stdout are ttys we may still have /dev/tty 
available to us.

e37c901cdc Get rid of the QNX TCSAFLUSH -> TCSADRAIN hack. If QNX still has this 
problem we'll need to revisit this again.

ee04914164 Add support for running a helper program to read the password when 
no tty is present (or when specified with the -A flag).  TODO: docs.

ebcf3cf399 Use TCSAFLUSH when restoring terminal settings (and echo) to guarantee that any pending output is discarded 2008-01-16 18:03:08 +00:00
Todd C. Miller
45a382bba1 Instead of defining a macro to call the appropriate method for 
turning on/off echo, just define tc[gs]etattr() and the related
defines that use the correct terminal ioctls if needed.
Also go back to using TCSAFLUSH instead of TCSADRAIN on all but QNX.

c84ad26835 Avoid printing the prompt if we are already backgrounded. 
E.g. if the user runs "sudo foo &" from the shell.  In this
case, the call to tcsetattr() will cause SIGTTOU to be delivered.

2c2daa8eca Use: #include <config.h> 
Not: #include "config.h"
That way we get the correct config.h when build dir != src dir

f8176ceda2 Use SA_INTERRUPT so SunOS works correctly, avoid stdio and just use read/write 
as it is simpler.

47b833d4c2 Use alarm() instead of select() for the timeout for systems that don't 
fully/properly implement select().

6d6d4628f4 Add support for interrupting/suspending tgetpass via keyboard input. 
If you suspend sudo from the password prompt and resume it will
re-prompt you.

d76537718b When writing prompt, no need to write the NUL as well; hag@linnaean.org 2000-08-11 19:41:28 +00:00

54fbe08545 Added -S flag (read passwd from stdin) and tgetpass_flags global 
that holds flags to be passed in to tgetpass().  Change echo_off
param to tgetpass() into a flags field.  There are currently 2
possible flags for tgetpass(): TGP_ECHO and TGP_STDIN.  In tgetpass(),
abstract the echo set/clear via macros and if (flags & TGP_ECHO)
but echo is not set on the terminal, but sure to set it.

68fd7e74c1 When read()'ing, do a single character at a time to be sure we don't go 
oast the newline.

3f1581ae66 Make this work again for things like "sudo echo hi | more" where the tty 
gets put into character at a time mode.  We read until we read end of
line or we run out of space (similar to fgets(3)).

Block SIGINT and SIGTSTP during auth
remove a useless umask setting
Change error from BAD_ALLOCATION -> BAD_AUTH_INIT (for use with sia/PAM)
Some cosmetic changes to auth.c for consistency

850a52aa6f o Replace _PASSWD_LEN braindeath with our own SUDO_MAX_PASS. 
It turns out the old DES crypt does the right thing with passwords
   longert than 8 characters.
 o Fix common typo (necesary -> necessary)
 o Update TODO list
