From c1de1178254c786d9cd4fe2b36f72e6e26778f57 Mon Sep 17 00:00:00 2001 From: Jasper Lievisse Adriaanse Date: Sat, 15 Apr 2017 09:39:13 +0200 Subject: [PATCH] Rename all PAM-independant variables/comments. there is nothing PAM-specific about pam_state or pam_state_t. therefore rename them to be authenticator independant. --- i3lock.c | 34 +++++++++++++++++----------------- unlock_indicator.c | 34 +++++++++++++++++----------------- unlock_indicator.h | 10 +++++----- xcb.c | 4 ++-- 4 files changed, 41 insertions(+), 41 deletions(-) diff --git a/i3lock.c b/i3lock.c index 761ed32..2110fef 100644 --- a/i3lock.c +++ b/i3lock.c @@ -59,11 +59,11 @@ bool unlock_indicator = true; char *modifier_string = NULL; static bool dont_fork = false; struct ev_loop *main_loop; -static struct ev_timer *clear_pam_wrong_timeout; +static struct ev_timer *clear_auth_wrong_timeout; static struct ev_timer *clear_indicator_timeout; static struct ev_timer *discard_passwd_timeout; extern unlock_state_t unlock_state; -extern pam_state_t pam_state; +extern auth_state_t auth_state; int failed_attempts = 0; bool show_failed_attempts = false; bool retry_verification = false; @@ -206,13 +206,13 @@ static void finish_input(void) { } /* - * Resets pam_state to STATE_PAM_IDLE 2 seconds after an unsuccessful + * Resets auth_state to STATE_AUTH_IDLE 2 seconds after an unsuccessful * authentication event. * */ -static void clear_pam_wrong(EV_P_ ev_timer *w, int revents) { - DEBUG("clearing pam wrong\n"); - pam_state = STATE_PAM_IDLE; +static void clear_auth_wrong(EV_P_ ev_timer *w, int revents) { + DEBUG("clearing auth wrong\n"); + auth_state = STATE_AUTH_IDLE; redraw_screen(); /* Clear modifier string. */ @@ -222,9 +222,9 @@ static void clear_pam_wrong(EV_P_ ev_timer *w, int revents) { } /* Now free this timeout. */ - STOP_TIMER(clear_pam_wrong_timeout); + STOP_TIMER(clear_auth_wrong_timeout); - /* retry with input done during pam verification */ + /* retry with input done during auth verification */ if (retry_verification) { retry_verification = false; finish_input(); @@ -248,8 +248,8 @@ static void discard_passwd_cb(EV_P_ ev_timer *w, int revents) { } static void input_done(void) { - STOP_TIMER(clear_pam_wrong_timeout); - pam_state = STATE_PAM_VERIFY; + STOP_TIMER(clear_auth_wrong_timeout); + auth_state = STATE_AUTH_VERIFY; unlock_state = STATE_STARTED; redraw_screen(); @@ -271,7 +271,7 @@ static void input_done(void) { fprintf(stderr, "Authentication failure\n"); /* Get state of Caps and Num lock modifiers, to be displayed in - * STATE_PAM_WRONG state */ + * STATE_AUTH_WRONG state */ xkb_mod_index_t idx, num_mods; const char *mod_name; @@ -305,7 +305,7 @@ static void input_done(void) { } } - pam_state = STATE_PAM_WRONG; + auth_state = STATE_AUTH_WRONG; failed_attempts += 1; clear_input(); if (unlock_indicator) @@ -314,7 +314,7 @@ static void input_done(void) { /* Clear this state after 2 seconds (unless the user enters another * password during that time). */ ev_now_update(main_loop); - START_TIMER(clear_pam_wrong_timeout, TSTAMP_N_SECS(2), clear_pam_wrong); + START_TIMER(clear_auth_wrong_timeout, TSTAMP_N_SECS(2), clear_auth_wrong); /* Cancel the clear_indicator_timeout, it would hide the unlock indicator * too early. */ @@ -393,7 +393,7 @@ static void handle_key_press(xcb_key_press_event_t *event) { if ((ksym == XKB_KEY_j || ksym == XKB_KEY_m) && !ctrl) break; - if (pam_state == STATE_PAM_WRONG) { + if (auth_state == STATE_AUTH_WRONG) { retry_verification = true; return; } @@ -725,7 +725,7 @@ static void xcb_check_cb(EV_P_ ev_check *w, int revents) { /* * This function is called from a fork()ed child and will raise the i3lock * window when the window is obscured, even when the main i3lock process is - * blocked due to PAM. + * blocked due to the authentication backend. * */ static void raise_loop(xcb_window_t window) { @@ -985,7 +985,7 @@ int main(int argc, char *argv[]) { cursor = create_cursor(conn, screen, win, curs_choice); /* Display the "locking…" message while trying to grab the pointer/keyboard. */ - pam_state = STATE_PAM_LOCK; + auth_state = STATE_AUTH_LOCK; grab_pointer_and_keyboard(conn, screen, cursor); pid_t pid = fork(); @@ -1012,7 +1012,7 @@ int main(int argc, char *argv[]) { errx(EXIT_FAILURE, "Could not initialize libev.
