During network namespace stop process kernel side netlink sockets belonging to a namespace should be closed. They should not prevent namespace to stop, so they do not increment namespace usage counter. Though this counter will be put during last sock_put. The raplacement of the correct netns for init_ns solves the problem only partial as socket to be stoped until proper stop is a valid netlink kernel socket and can be looked up by the user processes. This is not a problem until it resides in initial namespace (no processes inside this net), but this is not true for init_net. So, hold the referrence for a socket, remove it from lookup tables and only after that change namespace and perform a last put. Signed-off-by:

Create a specific helper for netlink kernel socket disposal. This just let the code look better and provides a ground for proper disposal inside a namespace. Signed-off-by:

Network namespace allocates 2 kernel netlink sockets, fibnl & rtnl. These sockets should be disposed properly, i.e. by sock_release. Plain sock_put is not enough. Signed-off-by:

Netlink protocol table is global for all namespaces. Some netlink protocols have been virtualized, i.e. they have per/namespace netlink socket. This difference can easily lead to double free if more than 1 namespace is started. Count the number of kernel netlink sockets to track that this table is not used any more. Signed-off-by:

Alexey Dobriyan reported an oops when unsharing the network indefinitely inside a loop. This is because the ip6_frag is not per namespace while the ctls are. That happens at the fragment timer expiration: inet_frag_secret_rebuild function is called and this one restarts the timer using the value stored inside the sysctl field. "mod_timer(&f->secret_timer, now + f->ctl->secret_interval);" When the network is unshared, ip6_frag.ctl is initialized with the new sysctl instances, but ip6_frag has only one instance. A race in this case will appear because f->ctl can be modified during the read access in the timer callback. Until the ip6_frag is not per namespace, I discard the assignation to the ctl field of ip6_frags in ip6_frag_sysctl_init when the network namespace is not the init net.

Currently, all non TAH equipped 4xx PPC's call emac_start_xmit() upon xmit. This routine doesn't check if the frame length exceeds the max. MAL buffer size. This patch now changes the driver to call emac_start_xmit_sg() on all GigE platforms and not only the TAH equipped ones (440GX). This enables an MTU of 9000 instead 4080. Signed-off-by:

This patch changes the iwlwifi driver to properly support monitor interfaces after the filter flags change. The patch is originally created by Johannes Berg for iwl4965. I fixed some of the comments and created a similar patch for iwl3945. Signed-off-by:

sizeof(*cmd) is going to give the total size of the data structure that we allocated, more often than not. But the size of the command to be _sent_ could be a lot smaller, as it is in the KEY_MATERIAL and SUBSCRIBE_EVENT commands for example. So swap them round; let the caller set the _command_ size explicitly in the header, and infer the maximum response size from the data structure. Signed-off-by:

We don't necessarily want to reset the device on a TX timeout. But more often than not, the real cause is that the firmware has crapped itself, not just that the network is busy. So submit any harmless command, and if _that_ times out, then the error handling code will reset the module, as appropriate. Signed-off-by:

Even if it fails, we want to wait a while and try again, with an ultimate timeout if it the condition persists. So again, just use the standard command timeout behaviour. Signed-off-by:

When the firmware returns 0x0004, it wants us to try again later. We can achieve that simply by throwing out the response and letting the command timeout code kick in. Signed-off-by:

If we don't scribble over the command we sent, then we can retry it when the firmware responds with 0x0004 (which means -EAGAIN). Signed-off-by:

We have a local variable 'resp' which we use for this. So use it, instead of typing the whole thing. In preparation for actually using priv->upld_buf for the responses instead... Signed-off-by:

Otherwise, we go into an endless busy loop trying to enable PS mode when the command queue is empty, dealing with the error response, and then trying to enable PS mode again because the command queue is empty.... it doesn't really save much power. Signed-off-by:

DNLD_RES_RECEIVED is a bit of a misnomer -- we never wait for the result to be received; it's purely representing the state of the TX path, and in this case the TX path is definitely busy. Of course, that means that we don't actually care about DATA_SENT vs. CMD_SENT either, but that's a can of worms for another day... Signed-off-by:

Commit 5b8845345e7385d2eb37fac22ba9ab6905988be5 (or, in case the git workflow is broken and patches get recommitted, the commit entitled 'libertas: rename and re-type bufvirtualaddr to cmdbuf' by dcbw), introduced a number of bugs where we once had a pointer to a command _payload_, but now we use the pointer to the command header instead. The fix isn't wonderfully pretty for now, but it'll get better when we finish converting all commands so the structures include the header. Signed-off-by:
