dea75bdfa5 [IPCONFIG]: The kernel gets no IP from some DHCP servers
From: Stephen Hemminger <shemminger@linux-foundation.org>

Based upon a patch by Marcel Wappler:
 
   This patch fixes a DHCP issue of the kernel: some DHCP servers
   (i.e.  in the Linksys WRT54Gv5) are very strict about the contents
   of the DHCPDISCOVER packet they receive from clients.
 
   Table 5 in RFC2131 page 36 requests the fields 'ciaddr' and
   'siaddr' MUST be set to '0'.  These DHCP servers ignore Linux
   kernel's DHCP discovery packets with these two fields set to
   '255.255.255.255' (in contrast to popular DHCP clients, such as
   'dhclient' or 'udhcpc').  This leads to a not booting system.

There are some place, that calculate the ARP header length. These
calculations are correct, but 
 a) some operate with "magic" constants,
 b) enlarge the code length (sometimes at the cost of coding style),

92ffb85dd3 [IPV4] ipconfig: Fix regression in ip command line processing
The recent changes for ip command line processing fixed some problems
but unfortunately broke some common usage scenarios.  In current
2.6.24-rc6 the following command line results in no IP address
assignment, which is surely a regression:

 ip=10.0.2.15::10.0.2.2:255.255.255.0::eth0:off

Please find below a patch that works for all cases I can find.

9cecd07c3f [IPV4] Fix ip=dhcp regression
David Brownell pointed out a regression in my recent "Fix ip command
line processing" patch. It turns out to be a fairly blatant oversight on
my part whereby ic_enable is never set, and thus autoconfiguration is
never enabled. Clearly my testing was broken :-(

The solution that I have is to set ic_enable to 1 if we hit
ip_auto_config_setup(), which basically means that autoconfiguration is
activated unless told otherwise. I then flip ic_enable to 0 if ip=off,
ip=none, ip=::::::off or ip=::::::none using ic_proto_name();

The incremental patch is below, let me know if a non-incremental version
is prepared, as I did as for the original patch to be reverted pending a
fix.

a6c05c3d06 [IPV4]: Fix ip command line processing.
Recently the documentation in Documentation/nfsroot.txt was
update to note that in fact ip=off and ip=::::::off as the
latter is ignored and the default (on) is used.

This was certainly a step in the direction of reducing confusion.
But it seems to me that the code ought to be fixed up so that
ip=::::::off actually turns off ip autoconfiguration.

This patch also notes more specifically that ip=on (aka ip=::::::on)
is the default.

881d966b48 [NET]: Make the device list and device lookups per namespace.
This patch makes most of the generic device layer network
namespace safe.  This patch makes dev_base_head a
network namespace variable, and then it picks up
a few associated variables.  The functions:
dev_getbyhwaddr
dev_getfirsthwbytype
dev_get_by_flags
dev_get_by_name
__dev_get_by_name
dev_get_by_index
__dev_get_by_index
dev_ioctl
dev_ethtool
dev_load
wireless_process_ioctl

were modified to take a network namespace argument, and
deal with it.

vlan_ioctl_set and brioctl_set were modified so their
hooks will receive a network namespace argument.

So basically anthing in the core of the network stack that was
affected to by the change of dev_base was modified to handle
multiple network namespaces.  The rest of the network stack was
simply modified to explicitly use &init_net the initial network
namespace.  This can be fixed when those components of the network
stack are modified to handle multiple network namespaces.

For now the ifindex generator is left global.

Fundametally ifindex numbers are per namespace, or else
we will have corner case problems with migration when
we get that far.

At the same time there are assumptions in the network stack
that the ifindex of a network device won't change.  Making
the ifindex number global seems a good compromise until
the network stack can cope with ifindex changes when
you change namespaces, and the like.

457c4cbc5a [NET]: Make /proc/net per network namespace
This patch makes /proc/net per network namespace.  It modifies the global
variables proc_net and proc_net_stat to be per network namespace.
The proc_net file helpers are modified to take a network namespace argument,
and all of their callers are fixed to pass &init_net for that argument.
This ensures that all of the /proc/net files are only visible and
usable in the initial network namespace until the code behind them
has been updated to be handle multiple network namespaces.

Making /proc/net per namespace is necessary as at least some files
in /proc/net depend upon the set of network devices which is per
network namespace, and even more files in /proc/net have contents
that are relevant to a single network namespace.

dcbdc93c6c [IPCONFIG]: ip_auto_config fix
The following commandline:

 root=/dev/mtdblock6 rw rootfstype=jffs2 ip=192.168.1.10:::255.255.255.0:localhost.localdomain:eth1:off console=ttyS0,115200

makes ip_auto_config fall back to DHCP and complain "IP-Config: Incomplete
network configuration information." depending on if CONFIG_IP_PNP_DHCP is
set or not.

The only way I can make ip_auto_config accept my IP config is to add an
entry for the server IP:

ip=192.168.1.10:192.168.1.15::255.255.255.0:localhost.localdomain:eth1:off

I think this is a bug since I am not using a NFS root FS.

The following patch fixes the above problem.

From: Andrew Morton <akpm@linux-foundation.org>

Davem said (in February!):

  Well, first of all the change in question is not in 2.4.x either.  I just
  checked the current 2.4.x GIT tree and the test is exactly:

	if (ic_myaddr == INADDR_NONE ||
#ifdef CONFIG_ROOT_NFS
	    (MAJOR(ROOT_DEV) == UNNAMED_MAJOR
	     && root_server_addr == INADDR_NONE
	     && ic_servaddr == INADDR_NONE) ||
#endif
	    ic_first_dev->next) {

  which matches 2.6.x

  I even checked 2.4.x when it was branched for 2.5.x and the test was the
  same at the point in time too.

  Looking at the proposed change a bit it appears that it is probably
  correct, as it's trying to check that ROOT_DEV is nfs root.  But if it is
  correct then the UNNAMED_MAJOR comparison in the same code block should be
  removed as it becomes superfluous.

  I'm happy to apply this patch with that modification made.

This patch turns the RTNL from a semaphore to a new 2.6.16 mutex and
gets rid of some of the leftover legacy.

14c850212e [INET_SOCK]: Move struct inet_sock & helper functions to net/inet_sock.h
To help in reducing the number of include dependencies, several files were
touched as they were getting needed headers indirectly for stuff they use.

Thanks also to Alan Menegotto for pointing out that net/dccp/proto.c had
linux/dccp.h include twice.

121caf577d [NET]: fix-up schedule_timeout() usage
Use schedule_timeout_{,un}interruptible() instead of
set_current_state()/schedule_timeout() to reduce kernel size.  Also use
human-time conversion functions instead of hard-coded division to avoid
rounding issues.

43d60661ac [IPV4]: net/ipv4/ipconfig.c should #include <linux/nfs_fs.h>
Every file should #include the header files containing the prototypes of 
it's global functions.

nfs_fs.h contains the prototype of root_nfs_parse_addr().

f2ccd8fa06 [NET]: Kill skb->real_dev
Bonding just wants the device before the skb_bond()
decapsulation occurs, so simply pass that original
device into packet_type->func() as an argument.

It remains to be seen whether we can use this same
exact thing to get rid of skb->input_dev as well.

7a1af5d7bb [IPV4]: ipconfig.c: fix dhcp timeout behaviour
I think there is a small bug in ipconfig.c in case IPCONFIG_DHCP is set
and dhcp is used.

When a DHCPOFFER is received, ip address is kept until we get DHCPACK.
If no ack is received, ic_dynamic() returns negatively, but leaves the
offered ip address in ic_myaddr.

This makes the main loop in ip_auto_config() break and uses the maybe
incomplete configuration.

Not sure if it's the best way to do, but the following trivial patch
correct this.
