A word is defined to be a character + * string beginning and/or ending with the characters + * A-Z a-z 0-9 and _. It must also be preceded and/or + * followed by any character outside those mentioned. + * + * [10] a composite regular expression xy where x and y + * are in the form [1] to [10] matches the longest + * match of x followed by a match for y. + * + * [11] ^ a regular expression starting with a ^ character + * $ and/or ending with a $ character, restricts the + * pattern matching to the beginning of the line, + * or the end of line.

In our case, since we + * override this with our sasl data (see below nsldapi_sasl_install), we need to restore + * the previous value so that the layer below us (i.e. prldap) can use the lpoll_socketarg + * which it sets. + * So how do which know which fds[i] is a "sasl" fd? + * We initialize the lextiof_session_private *arg (see nsldapi_sasl_install) to point to + * the socket_private data in sb->sb_ext_io_fns.lbextiofn_socket_arg for "sasl" sockets, + * which is then used to initialize lpoll_socketarg (see above). + * So, if the arg which gets passed into nsldapi_sasl_poll is the same as the + * fds[i].lpoll_socketarg, we know it is a "sasl" socket and we need to "pop" the sasl + * layer. We do this by replacing lpoll_socketarg with the one we saved when we "pushed" + * the sasl layer. + * So why the loop to restore the sasl lpoll_socketarg? + * The lower layer only uses lpoll_socketarg during poll(). See ldappr-io.c:prldap_poll() + * for more information about how that works. However, after the polling is done, there + * is some special magic in os-ip.c in the functions nsldapi_add_to_cb_pollfds(), + * nsldapi_clear_from_cb_pollfds(), and nsldapi_find_in_cb_pollfds() to find the correct + * Sockbuf to operate on. This is the macro NSLDAPI_CB_POLL_MATCH(). For the extended + * io function callbacks to work correctly, it is not sufficient to say that the file + * descriptor in the Sockbuf matches the one that poll says has activity - we also need + * to match the lpoll_socketarg with the sb->sb_ext_io_fns.lbextiofn_socket_arg to make + * sure this really is the Sockbuf we want to use. So we have to restore the + * lpoll_socketarg with the original one. + * Why have origarg and staticorigarg? + * To avoid malloc. The sizeof staticorigarg should be large enough to accomodate almost + * all clients without incurring too much additional overhead. However, if we need more + * room, origarg will grow to nfds.
