I'm running into a segfault when I try to use "attr -l /mnt/glusterfs" on a gluster path:

#0  0x00002aaaaad3e887 in strncmp () from /lib64/libc.so.6
#1  0x00002aaaaabc7266 in api_unconvert (name=0x7fff987f1990 "glusterfs.test", linuxname=0x7fff987f5000 <Address 0x7fff987f5000 out of bounds>, irixflags=1) at libattr.c:72
#2  0x00002aaaaabc808f in attr_list (path=0x7fff987f37b3 "/mnt/glusterfs", buffer=0x503000 "\001", buffersize=61440, flags=1, cursor=0x7fff987f1b10) at libattr.c:293
#3  0x0000000000400f05 in main (argc=<value optimized out>, argv=<value optimized out>) at attr.c:225

Maybe something isn't being properly exposed in fuse? This is with attr-2.4.28-1.2. This is happens every time so let me know if you need more info.

The relevant code from attr is calling this:

int
attr_list(const char *path, char *buffer, const int buffersize, int flags,
	  attrlist_cursor_t *cursor)
{
	const char *l;
	int length, count = 0;
	char lbuf[MAXLISTLEN];
	char name[MAXNAMELEN+16];
	unsigned int start_offset, end_offset;

	if (buffersize < sizeof(attrlist_t)) {
		errno = EINVAL;
		return -1;
	}
	bzero(buffer, sizeof(attrlist_t));

	if (flags & ATTR_DONTFOLLOW)
		length = llistxattr(path, lbuf, sizeof(lbuf));
	else
		length = listxattr(path, lbuf, sizeof(lbuf));
	if (length <= 0)
		return length;

	start_offset = sizeof(attrlist_t);
	end_offset = buffersize & ~(8-1);	/* 8 byte align */

	for (l = lbuf; l != lbuf + length; l = strchr(l, '\0') + 1) {
		if (api_unconvert(name, l, flags))
			continue;
		if (flags & ATTR_DONTFOLLOW)
			length = lgetxattr(path, l, NULL, 0);
		else
			length =  getxattr(path, l, NULL, 0);
		if (length < 0 && (errno == ENOATTR || errno == ENOTSUP))
			continue;
		if (count++ < cursor->opaque[0])
			continue;
		if (attr_list_pack(name, length, buffer, buffersize,
				   &start_offset, &end_offset)) {
			cursor->opaque[0] = count;
			break;
		}
	}
	return 0;
}
