Subject: [PATCH] change stop condition to avoid infinite loops
|
|
|
f725e3 |
|
|
|
f725e3 |
In net/net.c there is a while (1) that only exits if there is a stop
|
|
|
f725e3 |
condition and more then 10 packages or if there is no package received.
|
|
|
f725e3 |
|
|
|
f725e3 |
If GRUB is idle and enter in this loop, the only condition to leave is
|
|
|
f725e3 |
if it doesn't have incoming packages. In a network with heavy traffic
|
|
|
f725e3 |
this never happens.
