	* src/daemon.c (daemon_init): When backgrounding, let the parent
	process use _exit rather than exit. We used to let the
	intermediate process wait on the child, in order to print out a
	message for any unexpected status code. But then we get a race in
	the testsuite, because that process may keep the listen sockets
	open even after the main process has deleted its pid file.

	daemon_close_fds. When --daemonic --no-syslog is given, still perform all
	daemonic processing except for the redirect of stderr to /dev/null.

	* src/daemon.h: Updated prototypes. Deleted C++ guard.

	* src/daemon.c (daemon_pidfile): Deleted #if:ed out file locking
	code.
	(daemon_started_by_init, daemon_started_by_inetd): Made static.
	(daemon_detect): New function, split out from daemon_init.
	(daemon_dup_null): Likewise.
	(getdtablesize): New function, for systems that don't have it in
	libc.
	(daemon_close_fds): New function.
	(daemon_init): New argument with the daemon mode. Split handling
	of fd:s to the new functions daemon_dup_null and daemon_close_fds.

2006-04-28  Niels M�ller  <niels@s3.kth.se>

	leak any fd:s to child processes.

	* doc/index.html: Updated sshtools link, after prodding from
	Jerrad Pierce.

	* src/werror.c (werror_argp_parser): Likewise.
	* src/server_pty.c (pty_open_master): Likewise.
	* src/unix_interact.c (make_unix_interact): Likewise (even if this
	is in the client).
	* src/io.c (lsh_pushd_fd): Likewise.
	(lsh_pushd): Likewise. Also fixed EINTR logic.

2005-11-28  Niels M�ller  <nisse@lysator.liu.se>

	* src/testsuite/lcp-test: Skip test if /bin/bash doesn't exist.

	as is.

	* .bootstrap: Don't exit if src/nettle/aclocal.m4 already exists.
	Make all symlinks before checking for the "links" argument.

	* configure.ac (LSH_GCC_FUNCTION_NAME): Deleted use of this macro.
	Deleted the checks for the sizes of short, int and long. Use
	-Wno-pointer-sign when compiling with gcc-4.x.

2005-11-25  Niels M�ller  <niels@s3.kth.se>

	* misc/run-tests: New -v option, propagated to test programs.

2002-03-19  Niels M�ller  <nisse@lysator.liu.se>

	* src/io.c (address_info2sockaddr): Prefer AF_INET addresses over
	AF_INET6 (as it seems common that localhost has an ipv6 address
	that doesn't work). Even better would be to try all addresses, but
	that has to wait for later.

2002-03-19  Pontus Sk�ld  <pont@docs.uu.se>

	both utmpx and utmp is available. Also, don't search for an
	existing entry but construct a new one and putut{,x}line it.
	Don't clear fields explicitly (the memset).
	
	(utmp_book_keeping): Prefer utmpx, and don't search for existing

	* src/server_session.c (make_pty): Simple bugfix, pty->master was

	it's not opened yet).
	(pty_open_master): Renamed the pty_allocate function. Now opens

	process of the lshd server (if it's running in daemonic mode).
	(pty_open_slave): Renamed function tty_setctty. Now responsible
	also for opening the slave side of the pty, pushing STREAMS
	modules, and setting the tty state.

	signed int.
	(sftp_callback_func): New typedef.
	(struct sftp_callback): Changed prototype for nextfun. Changed
	UINT64 to off_t.
	Changed all prototypes to not pass and return structs without
	using pointers.

	* src/sftp/sftp_c.c: General change of calling conventions. Pass
	struct * and const struct *, instead of passing and returning
	structures "by-value".

	* src/sftp/buffer.c (sftp_packet_size): New function.
	(sftp_read_packet): Call clearerr after checking for error and
	eof.
