06eadf5ebf fix double free in grub_net_recv_tcp_packet
Using the http module to download config files, produces memory errors,
after the config file is downloaded.

The error was traced to the tcp stack in grub-core/net/tcp.c. The wrong
netbuff pointer was being freed in the clean up loop.

Changing the code to free the correct netbuff pointer removes the runtime
error.

Closes 42765.

7c4b6b7bb4 send router solicitation for ipv6 address autoconf v2
Many routers have long router advertisment interval configured by
default. The Neighbor Discovery protocol (RFC4861) has defined default
MaxRtrAdvInterval value as 600 seconds and
MinRtrAdvInterval as 0.33*MaxRtrAdvInterval. This makes
net_ipv6_autoconf fails more often than not as currently it passively
listens the RA message to perfom address autoconfiguration.

This patch tries to send router solicitation to overcome the problem of
long RA interval.

v2:
use cpu_to_be macro for network byte order conversion
add missing error handling

72ec399ad8 icmp6 fix no respond to neighbor solicit message
The structure size used in grub_netbuff_pull to get the pointer to
option header is apparently wrong, which leads to subsequent range check
failed and therefore not responding to any neighbor solicit message in my
testing.

d99d2f8416 change stop condition to avoid infinite loops
In net/net.c there is a while (1) that only exits if there is a stop
condition and more then 10 packages or if there is no package received.

If GRUB is idle and enter in this loop, the only condition to leave is
if it doesn't have incoming packages. In a network with heavy traffic
this never happens.
