I experienced the same symptoms with OSX 10.12.5 xorg-server @1.18.4_1 xorg-xtrans @1.3.5_0 It's a problem in xorg-xtrans. Relevant stack trace:

I found a bug in

/opt/local/include/X11/Xtrans/Xtranssock.c

function:

static XtransConnInfo
TRANS(SocketReopen) (int i _X_UNUSED, int type, int fd, const char *port)

Original code:

    /* Initialize ciptr structure as if it were a normally-opened unix socket */
    ciptr->flags = TRANS_LOCAL | TRANS_NOUNLINK;
#ifdef BSD44SOCKETS
    addr->sa_len = addrlen;
#endif
    addr->sa_family = AF_UNIX;
#ifdef HAS_STRLCPY
    strlcpy(addr->sa_data, port, portlen);
#else
    strncpy(addr->sa_data, port, portlen);
#endif

Definition of addr is:

    struct sockaddr *addr;

and definition of struct sockaddr in /usr/include/sys/socket.h is:

struct sockaddr {
        __uint8_t       sa_len;         /* total length */
        sa_family_t     sa_family;      /* [XSI] address family */
        char            sa_data[14];    /* [XSI] addr value (actually larger) */
};

So the strncpy tries to copy "portlen" bytes to 14 bytes. portlen is 57 in my case. Althoug enough memory was allocated ealier, some checking code in libsystem_c finds that 57 is greater than 14 and aborts.

I just changed portlen to 14 in the strncpy call and it works.

    /* Initialize ciptr structure as if it were a normally-opened unix socket */
    ciptr->flags = TRANS_LOCAL | TRANS_NOUNLINK;
#ifdef BSD44SOCKETS
    addr->sa_len = addrlen;
#endif
    addr->sa_family = AF_UNIX;
#ifdef HAS_STRLCPY
    strlcpy(addr->sa_data, port, portlen);
#else
    strncpy(addr->sa_data, port, 14);
#endif

Questions:

  • why is strncpy used although there is strlcpy in libsystem_c?
  • why does it work with a truncated port?

After waiting long enough X11.app eventually stopped crashing on me and started working. Unfortunately I wasn't watching, and don't know how long the crash loop took to escape.

comment:5 Changed 7 years ago by PaulForgey (Paul Forgey)

This code as written will not work in clang. As addr->sa_data is a char[14], it will always cause an overflow check. If you replace 'portlen' with a constant like, say, 20, you'll get a warning explaining this will happen.

Three ways to fix this:

1) #undef strncpy 2) do not use strncpy for the sa_data field of the abstract socket type 3) use an intermediate void pointer assigned to sa_data, then strncpy into it

Nope, while addr->sa_data is indeed declared as char[14], the POSIX spec allows it to be longer than that, as allowed by the sa_len.

I’ve had almost this exact discussion multiple times over the past year. I really hate struct sockaddr, but we’re stuck with it. IIRC, we fixed clang’s __builtin_object_size to address this case.

Ugg. Looks like this bug regressed in Xcode 8.3 for some reason. Xcode 9 is fine as are clang-4.0 and devel.

After the fix in 1c09549 macports tries to build using macports-clang-3.7 which leads to dozens of errors like the following:

           ^

Blacklisting macports-clang-3.7 as well leads to the following message:

Warning: All compilers are either blacklisted or unavailable; defaulting to first fallback option

Was anyone able to compile this on MacOS Sierra? If so, with what compiler?

Addendum: I just noticed that another user reported this as a new bug: https://trac.macports.org/ticket/54504

clang-4.0 worked just fine for me. I have it (but not clang-3.7) installed so it appears to have automatically selected it.
