* REPL Server: Guard against HTTP inter-protocol exploitation attacks....Reported by Christopher Allan Webber <cwebber@dustycloud.org> Co-authored-by: Ludovic Courtès <ludo@gnu.org> This commit adds protection to Guile's REPL servers against HTTP inter-protocol exploitation attacks, a scenario whereby an attacker can, via an HTML page, cause a web browser to send data to TCP servers listening on a loopback interface or private network. See <https://en.wikipedia.org/wiki/Inter-protocol_exploitation> and <https://www.jochentopf.com/hfpa/hfpa.pdf>, The HTML Form Protocol Attack (2001) by Tochen Topf <jochen@remote.org>. Here we add a procedure to 'before-read-hook' that looks for a possible HTTP request-line in the first line of input from the client socket. If present, the socket is drained and closed, and a loud warning is written to stderr (POSIX file descriptor 2). * module/system/repl/server.scm: Add 'maybe-check-for-http-request' to 'before-read-hook' when this module is loaded. (with-temporary-port-encoding, with-saved-port-line+column) (drain-input-and-close, permissive-http-request-line?) (check-for-http-request, guard-against-http-request) (maybe-check-for-http-request): New procedures. (serve-client): Use 'guard-against-http-request'. * module/system/repl/coop-server.scm (start-repl-client): Use 'guard-against-http-request'. * doc/ref/guile-invoke.texi (Command-line Options): In the description of the --listen option, make the security warning more prominent. Mention the new protection added here. Recommend using UNIX domain sockets for REPL servers. "a path to" => "the file name of". Mark H Weaver2017-03-011-5/+15

* Remove 'umask' calls from 'mkdir'....Fixes <http://bugs.gnu.org/24659>. * libguile/filesys.c (SCM_DEFINE): Remove calls to 'umask' when MODE is unbound; instead, use 0777 as the mode. Update docstring to clarify this. * doc/ref/posix.texi (File System): Adjust accordingly. * NEWS: Mention it. Ludovic Courtès2017-03-011-3/+4
* "select" no longer throws exception on EINTR...* doc/ref/posix.texi (Ports and File Descriptors): Update. * libguile/filesys.c (scm_select): Use scm_std_select so that pending interrupts can be delivered.

* Reimplement dynamic states...There are two goals: one, to use less memory per dynamic state in order to allow millions of dynamic states to be allocated in light-weight threading scenarios. The second goal is to prevent dynamic states from being actively mutated in two threads at once.
