Hello,
We were looking at the code
ecos/packages/net/common/current/src/tftp_server.c.
(ecos 3.x)
In the function 'tftpd_server(cyg_addrword_t p)', lines 647-668, the
iterator 'i' is used in 2 nested for loops:
for (i=0; i < CYGNUM_NET_MAX_INET_PROTOS; i++) {
if (server->s[i] && FD_ISSET(server->s[i],&readfds)) {
recv_len = sizeof(data);
from_len = sizeof(from_addr);
data_len = recvfrom(server->s[i], hdr, recv_len, 0,
&from_addr, &from_len);
if ( data_len < 0) {
diag_printf("TFTPD [%x]: can't read request\n", p);
} else {
#ifdef CYGSEM_NET_TFTPD_MULTITHREADED
// Close the socket and post on the semaphore some
// another thread can start listening for requests. This
// is not quite right. select could of returned with more than
// one socket with data to read. Here we only deal with one
of them
for (i=0; i < CYGNUM_NET_MAX_INET_PROTOS; i++) {
if (server->s[i]) {
close (server->s[i]);
server->s[i] = 0;
}
}
sem_post(server->port);
#endif
At first sight, I would say this is a bug, or am I wrong?
Kind regards,
Jürgen
