Description Larry Troan 2003-05-20 18:39:23 UTC
The network drivers are allocating large structures on the kernel stack.  When
several do this, and they get called in series, it can cause stack overflow. 
These structs should be allocated via kmalloc/kfree.
                                                                               
                                                                              
In the 2.4.9-e.18 kernel:
                                                                               
                                                                             e1000:
e1000_check_copper_options() uses 0x1d0 bytes.
e1000_ethtool_ioctl() uses 0x2c8 bytes.
e1000_check_options() uses 0x15c bytes.

Would it be ok to all parties involved, if I made this bug public?  I would like
Intel to be able to view it as well.  And since it's in issue present in
upstream, I believe this bug need not be private.

Sure looks like a DUP. Jeff, do you agree? If so, suggest closing this BUG as
DUP of 107552.
