* net: sctp: decouple cleaning some socket data from endpointDaniel Borkmann2013-06-252-10/+25
| | | | | | | | | | | | | | | | | Rather instead of having the endpoint clean the garbage from the socket, use a sk_destruct handler sctp_destruct_sock(), that does the job for that when there are no more references on the socket. At least do this for our crypto transform through crypto_free_hash() that is allocated when in listening state. Also, perform sctp_put_port() only when sk is valid. At a later point in time we can still determine if there's an option of placing this into sk_prot->unhash() or sctp_endpoint_free() without any races. For now, leave it in sctp_endpoint_destroy() though. Signed-off-by: Daniel Borkmann <dborkman@redhat.com> Acked-by: Vlad Yasevich <vyasevich@gmail.com> Signed-off-by: David S.

* net: sctp: migrate cookie life from timeval to ktimeDaniel Borkmann2013-06-255-50/+15
| | | | | | | | | | | | | | | | | | Currently, SCTP code defines its own timeval functions (since timeval is rarely used inside the kernel by others), namely tv_lt() and TIMEVAL_ADD() macros, that operate on SCTP cookie expiration. We might as well remove all those, and operate directly on ktime structures for a couple of reasons: ktime is available on all archs; complexity of ktime calculations depending on the arch is less than (reduces to a simple arithmetic operations on archs with BITS_PER_LONG == 64 or CONFIG_KTIME_SCALAR) or equal to timeval functions (other archs); code becomes more readable; macros can be thrown out.

| | | | | | | | | | | | | | | | If the tokenized ip address is re-set on an interface we depend on the arrival of a new router advertisment to call addrconf_verify to clean up the old address (which valid_lft is now set to 0). Old addresses can linger around for a longer time if e.g. the source of router advertisments vanishes. So, call addrconf_verify immediately after setting the new tokenized address to get rid of the old tokenized addresses.

* ipv6: split duplicate address detection and router solicitation timerHannes Frederic Sowa2013-06-252-75/+97
| | | | | | | | | | | | | | | | | | | | | | | | This patch splits the timers for duplicate address detection and router solicitations apart. The router solicitations timer goes into inet6_dev and the dad timer stays in inet6_ifaddr. The reason behind this patch is to reduce the number of unneeded router solicitations send out by the host if additional link-local addresses are created. Currently we send out RS for every link-local address on an interface. If the RS timer fires we pick a source address with ipv6_get_lladdr. This change could hurt people adding additional link-local addresses and specifying these addresses in the radvd clients section because we no longer guarantee that we use every ll address as source address in router solicitations.

* mlx4: allow order-0 memory allocations in RX pathEric Dumazet2013-06-252-86/+95
| | | | | | | | | | | | | | | | | | | | | | | | | Signed-off-by: Eric Dumazet <edumazet@google.com> mlx4 exclusively uses order-2 allocations in RX path, which are likely to fail under memory pressure. We therefore drop frames more than needed. This patch tries order-3, order-2, order-1 and finally order-0 allocations to keep good performance, yet allow allocations if/when memory gets fragmented. By using larger pages, and avoiding unnecessary get_page()/put_page() on compound pages, this patch improves performance as well, lowering false sharing on struct page. Also use GFP_KERNEL allocations in initialization path, as allocating 12 MB (390 order-3 pages) can easily fail with GFP_ATOMIC.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The lifetime of an irq_cpu_rmap is odd: we have to allocate it before installing IRQ handlers and free it before removing the IRQ handlers. As a result of this asymmetry, it was omitted from some failure paths. On another failure path, we could try to remove IRQ handlers we had not yet installed. Move the irq_cpu_rmap allocation and freeing alongside IRQ handler installation and removal, in efx_nic_{init,fini}_interrupts(). Count the number of IRQ handlers successfully installed and only remove those on the failure path. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

* | packet: nlmon: virtual netlink monitoring device for packet socketsDaniel Borkmann2013-06-243-0/+181
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, there is no good possibility to debug netlink traffic that is being exchanged between kernel and user space. Therefore, this patch implements a netlink virtual device, so that netlink messages will be made visible to PF_PACKET sockets. Once there was an approach with a similar idea [1], but it got forgotten somehow. I think it makes most sense to accept the "overhead" of an extra netlink net device over implementing the same functionality from PF_PACKET sockets once again into netlink sockets. We have BPF filters that can already be easily applied which even have netlink extensions, we have RX_RING zero-copy between kernel- and user space that can be reused, and much more features. So instead of re-implementing all of this, we simply pass the skb to a given PF_PACKET socket for further analysis. Another nice benefit that comes from that is that no code needs to be changed in user space packet analyzers (maybe adding a dissector, but not more), thus out of the box, we can already capture pcap files of netlink traffic to debug/troubleshoot netlink problems. Also thanks goes to Thomas Graf, Flavio Leitner, Jesper Dangaard Brouer.

* net: Unmap fragment page once iterator is doneWedson Almeida Filho2013-06-243-3/+6
| | | | | | | | | | | | | | Callers of skb_seq_read() are currently forced to call skb_abort_seq_read() even when consuming all the data because the last call to skb_seq_read (the one that returns 0 to indicate the end) fails to unmap the last fragment page. With this patch callers will be allowed to traverse the SKB data by calling skb_prepare_seq_read() once and repeatedly calling skb_seq_read() as originally intended (and documented in the original commit 677e90eda), that is, only call skb_abort_seq_read() if the sequential read is actually aborted.

Linville says: ==================== I would guess that this is the last big wireless pull request before the 3.11 merge window... Regarding the mac80211 bits, Johannes says: "I have a number of mesh fixes and improvements from Colleen, Jacob, Ashok and Thomas, powersave fixes in mac80211 from Alex, improved management-TX from Antonio, and a few various things, including locking fixes, from others and myself. Overall though, nothing really stands out." As for the iwlwifi bits, Johannes says: "Emmanuel contributed two AP mode fixes, removed an unused field, fixed a comment and added a warning for something that shouldn't happen in practice, and I removed the declaration of a function that doesn't even exist and cleaned up a small include." "This time I have a number of cleanups, a small fix from Emmanuel and two performance improvements that combined reduce our driver's CPU utilisation as much as 75% in high TX-throughput scenarios." "These two patches fix two issues with using rfkill randomly during traffic, which would then cause our driver to stop working and not be able to recover at all." Regarding the ath6kl bits, Kalle says: "Here are few simple patches for ath6kl. We have a suspend crash fix for USB from Shafi, use of mac_pton(), a compiler warning fix and a fix for module initialisation error path." Kalle also sends the biggest single item of note, the new ath10k driver for Qualcomm Atheros 802.11ac CQA98xx devices. Included is an NFC pull, of which Samuel says: "These are the pending NFC patches for the 3.11 merge window. It contains the pending fixes that were on nfc-fixes (nfc-fixes-3.10-2), along with a few more for the pn544 and pn533 drivers, the LLCP disconnection path and an LLCP memory leak. Highlights for this one are: - An initial secure element API. NFC chipsets can carry an embedded secure element or get access to the SIM one. In both cases they control the secure elements and this API provides a way to discover, enable and disable the available SEs. It also exports that to userspace in order for SE focused middleware to actually do something with them (e.g. payments). - NCI over SPI support. SPI is the most complex NCI specified transport layer and we now have support for it in the kernel. The next step will be to implement drivers for NCI chipsets using this transport like e.g. bcm2079x. - NFC p2p hardware simulation driver. We now have an nfcsim driver that is mostly a loopback device between 2 NFC interfaces. It also implements the rest of the NFC core API like polling and target detection. This driver, with neard running on top of it, allows us to completely test the LLCP, SNEP and Handover implementation without physical hardware. - A Firmware update netlink API. Most (All ?) HCI chipsets have a special firmware update mode where applications can push a new firmware that will be flashed. We now have a netlink API for providing that mode to e.g. nfctool." On top of all that, there are a variety of updates to brcmfmac, iwlegacy, rtlwifi, wil6210, and the TI wl12xx drivers. As usual, the bcma and ssb busses get a little love as well, as do a handful of others here and there. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
