2008-03-26[NET] NETNS: Omit sock->sk_net without CONFIG_NET_NS.YOSHIFUJI Hideaki
Introduce per-sock inlines: sock_net(), sock_net_set() and per-inet_timewait_sock inlines: twsk_net(), twsk_net_set(). Without CONFIG_NET_NS, no namespace other than &init_net exists. Let's explicitly define them to help compiler optimizations. Signed-off-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org>

2008-02-26[IPV4]: Reset scope when changing addressBjorn Mork
This bug did bite at least one user, who did have to resort to rebooting the system after an "ifconfig eth0 127.0.0.1" typo. Deleting the address and adding a new is a less intrusive workaround. But I still beleive this is a bug that should be fixed. Some way or another. Another possibility would be to remove the scope mangling based on address. This will always be incomplete (are 127/8 the only address space with host scope requirements?) We set the scope to RT_SCOPE_HOST if an IPv4 interface is configured with a loopback address (127/8). The scope is never reset, and will remain set to RT_SCOPE_HOST after changing the address. This patch resets the scope if the address is changed again, to restore normal functionality.

2008-01-28[NETNS]: Process inet_confirm_addr in the correct namespace.Denis V. Lunev
inet_confirm_addr can be called with NULL in_dev from arp_ignore iff scope is RT_SCOPE_LINK. Lets always pass the device and check for RT_SCOPE_LINK scope inside inet_confirm_addr. This let us take network namespace from in_device a need for an additional argument. Signed-off-by: Denis V. Lunev <den@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-01-28[IPV4]: Remove extra argument from arp_ignore.Denis V. Lunev
arp_ignore has two arguments: dev & in_dev. dev is used for inet_confirm_addr calling only. inet_confirm_addr, in turn, either gets in_dev from the device passed or iterates over all network devices if the device passed is NULL. It seems logical to directly pass in_dev into inet_confirm_addr. Signed-off-by: Denis V. Lunev <den@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-01-28[IPV4]: Switch users of ipv4_devconf(_all) to use the pernet onePavel Emelyanov
These are scattered over the code, but almost all the "critical" places already have the proper struct net at hand except for snmp proc showing function and routing rtnl handler. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-01-28[IPV4]: Switch users of ipv4_devconf_dflt to use the pernet onePavel Emelyanov
They are all collected in the net/ipv4/devinet.c file and mostly use the IPV4_DEVCONF_DFLT macro. So I add the net parameter to it and patch users accordingly. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-01-28[IPV4]: Move the devinet pointers on the struct netPavel Emelyanov
This is the core. Add all and default pointers on the netns_ipv4 and register a new pernet subsys to initialize them. Also add the ctl_table_header to register the net.ipv4.ip_forward ctl. I don't allocate additional memory for init_net, but use global devinets. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-01-28[IPV4]: Store the net pointer on devinet's ctl tablesPavel Emelyanov
Some handers and strategies of devinet sysctl tables need to know the net to propagate the ctl change to all the net devices. I use the (currently unused) extra2 pointer on the tables to get it. Holding the reference on the struct net is not possible, because otherwise we'll get a net->ctl_table->net circular dependency. But since the ctl tables are unregistered during the net destruction, this is safe to get it w/o additional protection. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-01-28[IPV4]: Make __devinet_sysctl_register return an errorPavel Emelyanov
Currently, this function is void, so failures in creating sysctls for new/renamed devices are not reported to anywhere. Fixing this is another complex (needed?) task, but this return value is needed during the namespaces creation to handle the case, when we failed to create "all" and "default" entries.

2008-01-28[IPV4]: Cleanup sysctl manipulations in devinet.cPavel Emelyanov
This includes: * moving neigh_sysctl_(un)register calls inside devinet_sysctl_(un)register ones, as they are always called in pairs; * making __devinet_sysctl_unregister() to unregister the ipv4_devconf struct, while original devinet_sysctl_unregister() works with the in_device to handle both - devconf and neigh sysctls; * make stubs for CONFIG_SYSCTL=n case to get rid of in-code ifdefs.

2008-01-28[INET]: Merge sys.net.ipv4.ip_forward and sys.net.ipv4.conf.all.forwardingPavel Emelyanov
AFAIS these two entries should do the same thing - change the forwarding state on ipv4_devconf and on all the devices. I propose to merge the handlers together using ctl paths. The inet_forward_change() is static after this and I move it higher to be closer to other "propagation" helpers and to avoid diff making patches based on { and } matching :) i.e. - make them easier to read.

2008-01-28[IPV4]: Use ctl paths to register devinet sysctlsPavel Emelyanov
This looks very much like the patch for neighbors. The path is also located on the stack and is prepared inside the function. This time, the call to the registering function is guarded with the RTNL lock, but I decided to keep it on the stack not to litter the devinet.c file with unneeded names and to make it look similar to the neighbors code. This is also intended to help us with the net namespaces and saves the vmlinux size as well - this time by more than 670 bytes. The difference from the first version is just the patch offsets, that changed due to changes in the patch #2.

2008-01-28[IPV4]: Unify and cleanup calls to devinet_sysctl_registerPavel Emelyanov
Currently this call is used to register sysctls for devices and for the "default" confs. The "all" sysctls are registered separately. Besides, the inet_device is passed to this function, but it is not needed there at all - just the device name and ifindex are required. Thanks to Herbert, who noticed, that this call doesn't even require the devconf pointer (the last argument) - all we need we can take from the in_device itself. The fix is to make a __devinet_sysctl_register(), which registers sysctls for all "devices" we need, including "default" and "all" :) The original devinet_sysctl_register() works with struct net_device, not the inet_device, and calls the introduced function, passing the device name and ifindex (to be used as procname and ctl_name) into it.

2008-01-28[IPV4]: Cleanup the devinet_sysctl_registerPavel Emelyanov
I moved the call to kmalloc() from the *t declaration into the code (this is confusing when a variable is initialized with the result of some call) and removed unneeded comment near the error path. Just like I did with the neigh ctl-s. Besides, I fixed the goto's and the labels - they were indented with spaces :( Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

So this patch deliberately disables all of the rtnletlink methods in everything except the initial network namespace. After the methods have been audited this extra check can be disabled.

2008-01-04[INET]: Fix netdev renaming and inet address labelsMark McLoughlin
When re-naming an interface, the previous secondary address labels get lost e.g. $> brctl addbr foo $> ip addr add 192.168.0.1 dev foo $> ip addr add 192.168.0.2 dev foo label foo:00 $> ip addr show dev foo | grep inet inet 192.168.0.1/32 scope global foo inet 192.168.0.2/32 scope global foo:00 $> ip link set foo name bar $> ip addr show dev bar | grep inet inet 192.168.0.1/32 scope global bar inet 192.168.0.2/32 scope global bar:2 Turns out to be a simple thinko in inetdev_changename() - clearly we want to look at the address label, rather than the device name, for a suffix to retain.

2007-12-11[IPV4]: Swap the ifa allocation with the"ipv4_devconf_setall" callPavel Emelyanov
According to Herbert, the ipv4_devconf_setall should be called only when the ifa is added to the device. However, failed ifa allocation may bring things into inconsistent state. Move the call to ipv4_devconf_setall after the ifa allocation. Fits both net-2.6 (with offsets) and net-2.6.25 (cleanly). Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S.

2007-10-10[IPV4]: When possible test for IFF_LOOPBACK and not dev == loopback_devEric W. Biederman

2007-10-10[IPV4]: Remove unnecessary test for the loopback device from inetdev_destroyEric W. Biederman
Currently we never call unregister_netdev for the loopback device so it is impossible for us to reach inetdev_destroy with the loopback device. So the test in inetdev_destroy is unnecessary. Further when testing with my network namespace patches removing unregistering the loopback device and calling inetdev_destroy works fine so there appears to be no reason for avoiding unregistering the loopback device.

2007-10-10[NET]: Dynamically allocate the loopback device, part 1.Daniel Lezcano

2007-10-10[NET]: Make the device list and device lookups per namespace.Eric W. Biederman
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. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-10-10[NET]: Make device event notification network namespace safeEric W. Biederman
Every user of the network device notifiers is either a protocol stack or a pseudo device. If a protocol stack that does not have support for multiple network namespaces receives an event for a device that is not in the initial network namespace it quite possibly can get confused and do the wrong thing. To avoid problems until all of the protocol stacks are converted this patch modifies all netdev event handlers to ignore events on devices that are not in the initial network namespace. As the rest of the code is made network namespace aware these checks can be removed. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-09-11[IPV4] devinet: show all addresses assigned to interfaceStephen Hemminger
Bug: http://bugzilla.kernel.org/show_bug.cgi?id=8876 Not all ips are shown by "ip addr show" command when IPs number assigned to an interface is more than 60-80 (in fact it depends on broadcast/label etc presence on each address). Steps to reproduce: It's terribly simple to reproduce: # for i in $(seq 1 100); do ip ad add 10.0.$i.1/24 dev eth10 ; done # ip addr show this will _not_ show all IPs.

2007-06-07[IPV4]: Restore old behaviour of default config valuesHerbert Xu
Previously inet devices were only constructed when addresses are added (or rarely in ipmr). Therefore the default config values they get are the ones at the time of these operations. Now that we're creating inet devices earlier, this changes the behaviour of default config values in an incompatible way (see bug #8519). This patch creates a compromise by setting the default values at the same point as before but only for those that have not been explicitly set by the user since the inet device's creation.

2007-06-07[IPV4]: Add default config support after inetdev_initHerbert Xu
Previously once inetdev_init has been called on a device any changes made to ipv4_devconf_dflt would have no effect on that device's configuration. This creates a problem since we have moved the point where inetdev_init is called from when an address is added to where the device is registered. This patch is the first half of a set that tries to mimic the old behaviour while still calling inetdev_init. It propagates any changes to ipv4_devconf_dflt to those devices that have not had the corresponding attribute set. The next patch will forcibly set all values at the point where inetdev_init was previously called. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

2007-06-07[IPV4]: Convert IPv4 devconf to an arrayHerbert Xu

2007-06-07[IPV4]: Only panic if inetdev_init fails for loopbackHerbert Xu

2007-02-14[PATCH] sysctl: remove insert_at_head from register_sysctlEric W. Biederman
The semantic effect of insert_at_head is that it would allow new registered sysctl entries to override existing sysctl entries of the same name. Which is pain for caching and the proc interface never implemented. I have done an audit and discovered that none of the current users of register_sysctl care as (excpet for directories) they do not register duplicate sysctl entries. So this patch simply removes the support for overriding existing entries in the sys_sysctl interface since no one uses it or cares and it makes future enhancments harder. Signed-off-by: Eric W.
