ipv4: Remove all uses of LL_ALLOCATED_SPACE

2015-02-20T00:49:23+00:00

commit 660882432909dbe611f1792eda158188065cb9f1 upstream.

ipv4: Remove all uses of LL_ALLOCATED_SPACE

The macro LL_ALLOCATED_SPACE was ill-conceived.  It applies the
alignment to the sum of needed_headroom and needed_tailroom.  As
the amount that is then reserved for head room is needed_headroom
with alignment, this means that the tail room left may be too small.

This patch replaces all uses of LL_ALLOCATED_SPACE in net/ipv4
with the macro LL_RESERVED_SPACE and direct reference to
needed_tailroom.

This also fixes the problem with needed_headroom changing between
allocating the skb and reserving the head room.

net: have ipconfig not wait if no dev is available

2011-12-20T19:09:15+00:00

previous commit 3fb72f1e6e6165c5f495e8dc11c5bbd14c73385c
makes IP-Config wait for carrier on at least one network device.

Before waiting (predefined value 120s), check that at least one device
was successfully brought up. Otherwise (e.g. buggy bootloader
which does not set the MAC address) there is no point in waiting
for carrier.

net: Add export.h for EXPORT_SYMBOL/THIS_MODULE to non-modules

2011-10-31T23:30:30+00:00

These files are non modular, but need to export symbols using
the macros now living in export.h -- call out the include so
that things won't break when we remove the implicit presence
of module.h from everywhere.

ipconfig: Reduce switch/case indent

2011-07-01T23:11:15+00:00

Make the case labels the same indent as the switch.

git diff -w shows miscellaneous 80 column wrapping.

ip: introduce ip_is_fragment helper inline function

2011-06-22T03:33:34+00:00

There are enough instances of this:

    iph->frag_off & htons(IP_MF | IP_OFFSET)

that a helper function is probably warranted.

ipconfig wait for carrier

2011-05-19T21:13:04+00:00

v3 -> v4: fix return boolean false instead of 0 for ic_is_init_dev

Currently the ip auto configuration has a hardcoded delay of 1 second.
When (ethernet) link takes longer to come up (e.g. more than 3 seconds),
nfs root may not be found.

Remove the hardcoded delay, and wait for carrier on at least one network
device.

ipconfig: send host-name in DHCP requests

2010-06-02T14:05:03+00:00

Normally dhclient can be configured to send the "host-name" option
in DHCP requests to update the client's DNS record. However for an
NFSROOT system, dhclient shall never be called (which may change the
IP addr and therefore lose your root NFS mount connection).

So enable updating the DNS record with kernel parameter

	ip=::::$HOST_NAME::dhcp
