From 38a608c55af7654f23c9a16129ab6211aac3b7ab Mon Sep 17 00:00:00 2001 From: Martin Mares Date: Mon, 31 May 2004 21:48:19 +0000 Subject: Rewritten the I/O loop. All socket operations are now safe, meaning that you can delete the socket from anywhere in the hooks and nothing should break. Also, the receive/transmit buffers are now regular xmalloc()'ed buffers, not separate resources which would need shuffling around between pools. sk_close() is gone, use rfree() instead. --- lib/socket.h | 8 +++----- 1 file changed, 3 insertions(+), 5 deletions(-) (limited to 'lib') diff --git a/lib/socket.h b/lib/socket.h index 147e5ce..bc4525f 100644 --- a/lib/socket.h +++ b/lib/socket.h @@ -1,7 +1,7 @@ /* * BIRD Socket Interface * - * (c) 1998--1999 Martin Mares + * (c) 1998--2004 Martin Mares * * Can be freely distributed and used under the terms of the GNU GPL. */ @@ -13,7 +13,7 @@ typedef struct birdsock { resource r; - pool *pool; /* Pool for socket data */ + pool *pool; /* Pool where incoming connections should be allocated (for SK_xxx_PASSIVE) */ int type; /* Socket type */ void *data; /* User data */ ip_addr saddr, daddr; /* IPA_NONE = unspecified */ @@ -38,12 +38,11 @@ typedef struct birdsock { int fd; /* System-dependent data */ node n; - int entered; + void *rbuf_alloc, *tbuf_alloc; } sock; sock *sk_new(pool *); /* Allocate new socket */ int sk_open(sock *); /* Open socket */ -void sk_close(sock *); /* Safe close of socket even from socket hook */ int sk_send(sock *, unsigned len); /* Send data, <0=err, >0=ok, 0=sleep */ int sk_send_to(sock *, unsigned len, ip_addr to, unsigned port); /* sk_send to given destination */ void sk_dump_all(void); @@ -68,7 +67,6 @@ sk_send_buffer_empty(sock *sk) #define SK_MAGIC 7 /* Internal use by sysdep code */ #define SK_UNIX_PASSIVE 8 #define SK_UNIX 9 -#define SK_DELETED 10 /* Internal use by sk_close */ /* * Multicast sockets are slightly different from the other ones: -- cgit v1.2.3
