* Display current tcp memory allocation in kmem cgroupGlauber Costa2011-12-12
| | | | | | | | | | | | This patch introduces kmem.tcp.usage_in_bytes file, living in the kmem_cgroup filesystem. It is a simple read-only file that displays the amount of kernel memory currently consumed by the cgroup.

* tcp buffer limitation: per-cgroup limitGlauber Costa2011-12-12
| | | | | | | | | | | | | | | | | | | This patch uses the "tcp.limit_in_bytes" field of the kmem_cgroup to effectively control the amount of kernel memory pinned by a cgroup. This value is ignored in the root cgroup, and in all others, caps the value specified by the admin in the net namespaces' view of tcp_sysctl_mem. If namespaces are being used, the admin is allowed to set a value bigger than cgroup's maximum, the same way it is allowed to set pretty much unlimited values in a real box.

| | | | | | | | | | | | | | This patch allows each namespace to independently set up its levels for tcp memory pressure thresholds. This patch alone does not buy much: we need to make this values per group of process somehow. This is achieved in the patches that follows in this patchset.

* tcp memory pressure controlsGlauber Costa2011-12-12
| | | | | | | | | | | | This patch introduces memory pressure controls for the tcp protocol. It uses the generic socket memory pressure code introduced in earlier patches, and fills in the necessary data in cg_proto struct.

* socket: initial cgroup code.Glauber Costa2011-12-12
| | | | | | | | | | | | | | | | | | | | | | | | The goal of this work is to move the memory pressure tcp controls to a cgroup, instead of just relying on global conditions. To avoid excessive overhead in the network fast paths, the code that accounts allocated memory to a cgroup is hidden inside a static_branch(). This branch is patched out until the first non-root cgroup is created. So when nobody is using cgroups, even if it is mounted, no significant performance penalty should be seen. This patch handles the generic part of the code, and has nothing tcp-specific.

* foundations of per-cgroup memory pressure controlling.Glauber Costa2011-12-12
| | | | | | | | | | | | | | | | | This patch replaces all uses of struct sock fields' memory_pressure, memory_allocated, sockets_allocated, and sysctl_mem to acessor macros. Those macros can either receive a socket argument, or a mem_cgroup argument, depending on the context they live in. Since we're only doing a macro wrapping here, no performance impact at all is expected in the case where we don't have cgroups disabled.

* xen-netfront: delay gARP until backend switches to ConnectedLaszlo Ersek2011-12-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After a guest is live migrated, the xen-netfront driver emits a gratuitous ARP message, so that networking hardware on the target host's subnet can take notice, and public routing to the guest is re-established. However, if the packet appears on the backend interface before the backend is added to the target host's bridge, the packet is lost, and the migrated guest's peers become unable to talk to the guest. A sufficient two-parts condition to prevent the above is: (1) ensure that the backend only moves to Connected xenbus state after its hotplug scripts completed, ie. the netback interface got added to the bridge; and (2) ensure the frontend only queues the gARP when it sees the backend move to Connected. These two together provide complete ordering. Sub-condition (1) is already satisfied by commit f942dc2552b8 in Linus' tree, based on commit 6b0b80ca7165 from [1]. In general, the full condition is sufficient, not necessary, because, according to [2], live migration has been working for a long time without satisfying sub-condition (2). However, after 6b0b80ca7165 was backported to the RHEL-5 host to ensure (1), (2) still proved necessary in the RHEL-6 guest. This patch intends to provide (2) for upstream.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | It looks like the regression was introduced between 20111202 and 20111205 (linux-next tree). Symptoms: connection to AP seem to be established, but no data goes though it in any way. Tested on intel 5300. Peek at the changes have shown that it looks like at least part of the code wasn't merged properly. It was originally committed into iwl_agn.c but code in question was moved to iwl-mac80211.c.

This is very inneficient because we send one or two blocks only per SDIO transaction and don't get the full benefits of sdio block transfers. This patch increases the chunk size to 16K. This more than doubles the transfer speed both in wl127x and wl128x chips, with greater impact on the latter: wl127x: 512 bytes chunk -> ~132ms 16384 bytes chunk -> ~57ms wl128x: 512 bytes chunk -> ~216ms 16384 bytes chunk -> ~37ms Signed-off-by: Luciano Coelho <coelho@ti.com>

With our card, this doesn't work correctly because it sets the block size FBR in the chip too early (ie. before the chip is powered on). Thus, if we don't set it explicitly, block mode remains disabled in the chip. If we try to send more data than fits in one block, the sdio driver will split it into separate blocks before sending to the chip. This causes problems because the chip is not expecting multiple blocks. At the moment this is not a problem, because we use chunks of 512 bytes for firmware upload and the data is always sent in byte mode. In the next patch, we will change the chunk size to a bigger value, so this patch is a preparation for that. Signed-off-by: Luciano Coelho <coelho@ti.com>
