However, when the allocated slave PTY `s' is already one of 0, 1, or 2, this causes unexpected closing of a standard stream. The same problem occurs when the file descriptor of the master PTY (the variable `m') is one of 0, 1, or 2. In this patch, the original master PTY (m) is closed before it would be overwritten by duplicated slave PTYs. The original slave PTY (s) is closed only when it is not one of the stanrad streams. --- st.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/st.c b/st.c index ebdf360..a9338e1 100644 --- a/st.c +++ b/st.c @@ -793,14 +793,15 @@ ttynew(const char *line, char *cmd, const char *out, char **args) break; case 0: close(iofd); + close(m); setsid(); /* create a new process group */ dup2(s, 0); dup2(s, 1); dup2(s, 2); if (ioctl(s, TIOCSCTTY, NULL) < 0) die("ioctl TIOCSCTTY failed: %s\n", strerror(errno)); - close(s); - close(m); + if (s > 2) + close(s); #ifdef __OpenBSD__ if (pledge("stdio getpw proc exec", NULL) == -1) die("pledge\n"); From 2f6e597ed871cff91c627850d03152cae5f45779 Mon Sep 17 00:00:00 2001 From: Hiltjo Posthuma Date: Tue, 24 Aug 2021 13:44:35 +0200 Subject: [PATCH 07/18] fix possible rare crash when Xutf8TextPropertyToTextList fails from the XmbTextListToTextProperty(3) man page: "If insufficient memory is available for the new value string, the functions return XNoMemory.

The following changes are made in this patch: - Fix tracking of pressed buttons. Previously, pressing two buttons and then releasing one would make st think no buttons are pressed, which in particular broke MODE_MOUSEMOTION. - Always send the lowest-numbered pressed button on motion events; when no button is pressed for a motion event in MODE_MOUSEMANY, then send a release. This matches the behaviour of xterm. (Previously, st sent the most recently pressed button in the motion report.) - Remove UB (?) access to potentially inactive struct member e->xbutton.button of XEvent union. - Fix (unlikely) possibility of overflow for large button numbers. The one discrepancy I found between st and xterm is that xterm sometimes encodes buttons with large numbers (>5) strangely. E.g., xterm reports presses of buttons 8 and 9 as releases, whereas st properly (?) encodes them as presses. --- x.c | 86 ++++++++++++++++++++++++++++++++++++------------------------- 1 file changed, 51 insertions(+), 35 deletions(-) diff --git a/x.c b/x.c index 8a16faa..5f4ea73 100644 --- a/x.c +++ b/x.c @@ -252,7 +252,7 @@ static char *opt_line = NULL; static char *opt_name = NULL; static char *opt_title = NULL; -static int oldbutton = 3; /* button event on startup: 3 = release */ +static uint buttons; /* bit field of pressed buttons */ void clipcopy(const Arg *dummy) @@ -364,61 +364,68 @@ mousesel(XEvent *e, int done) void mousereport(XEvent *e) { - int len, x = evcol(e), y = evrow(e), - button = e->xbutton.button, state = e->xbutton.state; + int len, btn, code; + int x = evcol(e), y = evrow(e); + int state = e->xbutton.state; char buf[40]; static int ox, oy; - /* from urxvt */ - if (e->xbutton.type == MotionNotify) { + if (e->type == MotionNotify) { if (x == ox && y == oy) return; if (!IS_SET(MODE_MOUSEMOTION) && !IS_SET(MODE_MOUSEMANY)) return; - /* MOUSE_MOTION: no reporting if no button is pressed */ - if (IS_SET(MODE_MOUSEMOTION) && oldbutton == 3) + /* MODE_MOUSEMOTION: no reporting if no button is pressed */ + if (IS_SET(MODE_MOUSEMOTION) && buttons == 0) return; - - button = oldbutton + 32; - ox = x; - oy = y; + /* Set btn to lowest-numbered pressed button, or 12 if no + * buttons are pressed. */ + for (btn = 1; btn <= 11 && !(buttons & (1<<(btn-1))); btn++) + ; + code = 32; } else { - if (!IS_SET(MODE_MOUSESGR) && e->xbutton.type == ButtonRelease) { - button = 3; - } else { - button -= Button1; - if (button >= 7) - button += 128 - 7; - else if (button >= 3) - button += 64 - 3; - } - if (e->xbutton.type == ButtonPress) { - oldbutton = button; - ox = x; - oy = y; - } else if (e->xbutton.type == ButtonRelease) { - oldbutton = 3; + btn = e->xbutton.button; + /* Only buttons 1 through 11 can be encoded */ + if (btn < 1 || btn > 11) + return; + if (e->type == ButtonRelease) { /* MODE_MOUSEX10: no button release reporting */ if (IS_SET(MODE_MOUSEX10)) return; - if (button == 64 || button == 65) + /* Don't send release events for the scroll wheel */ + if (btn == 4 || btn == 5) return; } + code = 0; } + ox = x; + oy = y; + + /* Encode btn into code.
