| * net: hold sock reference while processing tx timestampsRichard Cochran2011-10-242-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The pair of functions, * skb_clone_tx_timestamp() * skb_complete_tx_timestamp() were designed to allow timestamping in PHY devices. The first function, called during the MAC driver's hard_xmit method, identifies PTP protocol packets, clones them, and gives them to the PHY device driver. The PHY driver may hold onto the packet and deliver it at a later time using the second function, which adds the packet to the socket's error queue. As pointed out by Johannes, nothing prevents the socket from disappearing while the cloned packet is sitting in the PHY driver awaiting a timestamp. This patch fixes the issue by taking a reference on the socket for each such packet. In addition, the comments regarding the usage of these function are expanded to highlight the rule that PHY drivers must use skb_complete_tx_timestamp() to release the packet, in order to release the socket reference, too. These functions first appeared in v2.6.36.

| * | udplite: fast-path computation of checksum coverageGerrit Renker2011-10-181-32/+31Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 903ab86d195cca295379699299c5fc10beba31c7 of 1 March this year ("udp: Add lockless transmit path") introduced a new fast TX path that broke the checksum coverage computation of UDP-lite, which so far depended on up->len (only set if the socket is locked and 0 in the fast path). Fixed by providing both fast- and slow-path computation of checksum coverage. The latter can be removed when UDP(-lite)v6 also uses a lockless transmit path.

In the IP header of the ACK message, we choose to reflect TOS field of incoming message, and this might break some setups. Example of things that were broken : - Routing using TOS as a selector - Firewalls - Trafic classification / shaping We now remember in timewait structure the inet tos field and use it in ACK generation, and route lookup. Notes : - We still reflect incoming TOS in RST messages. - We could extend MuraliRaja Muniraju patch to report TOS value in netlink messages for TIME_WAIT sockets. - A patch is needed for IPv6 Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

I have systems running automated tests that that hit this condition in just a few days. Use a linux idr allocator to track which mavtap minor numbers are available and and to track the association between macvtap minor numbers and macvtap network devices. Remove the unnecessary unneccessary check to see if the network device we have found is indeed a macvtap device. With macvtap specific data structures it is impossible to find any other kind of networking device. Increase the macvtap minor range from 65536 to the full 20 bits that is supported by linux device numbers. It doesn't solve the original problem but there is no penalty for a larger minor device range. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: David S.

In the implementation of that we have two subtly different meanings of NULL. NULL meaning there is no tag on a directory entry and NULL meaning we don't care which namespace the lookup is performed for. This multiple uses of NULL have resulted in subtle bugs (since fixed) in the code. Currently it is only the bonding driver that needs to have an untagged file in a tagged directory. To untagle this mess I am adding support for tagged files to sysfs. Modifying the bonding driver to implement bonding_masters as a tagged file. Registering bonding_masters once for each network namespace. Then I am removing support for untagged entries in tagged sysfs directories. Resulting in code that is much easier to reason about.

Considering that skb_shared_info is larger than sk_buff, its time to take it into account for better memory accounting. This patch introduces SKB_TRUESIZE(X) macro to centralize various assumptions into a single place. At skb alloc phase, we put skb_shared_info struct at the exact end of skb head, to allow a better use of memory (lowering number of reallocations), since kmalloc() gives us power-of-two memory blocks. Unless SLUB/SLUB debug is active, both skb->head and skb_shared_info are aligned to cache lines, as before. Note: This patch might trigger performance regressions because of misconfigured protocol stacks, hitting per socket or global memory limits that were previously not reached. But its a necessary step for a more accurate memory accounting.

* | | | net-netlink: Add a new attribute to expose TOS values via netlinkMurali Raja2011-10-131-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch exposes the tos value for the TCP sockets when the TOS flag is requested in the ext_flags for the inet_diag request. This would mainly be used to expose TOS values for both for TCP and UDP sockets. Currently it is supported for TCP. When netlink support for UDP would be added the support to expose the TOS values would alse be done. For IPV4 tos value is exposed and for IPV6 tclass value is exposed.

| | * | | Bluetooth: Perform L2CAP SDU reassembly without copying dataMat Martineau2011-09-271-2/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use sk_buff fragment capabilities to link together incoming skbs instead of allocating a new skb for reassembly and copying. The new reassembly code works equally well for ERTM and streaming mode, so there is now one reassembly function instead of two.

| * | | | mac80211: Send nullfunc frames at lower rate during connection monitorRajkumar Manoharan2011-10-031-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recently mac80211 was changed to use nullfunc instead of probe request for connection monitoring for tx ack status reporting hardwares. Sometimes in congested network, STA got disconnected quickly after the association. It was observered that the rate control was not adopted to environment due to minimal transmission. As the nullfunc are used for monitoring purpose, these frames should not be sacrificed for rate control updation. So it is better to send the monitoring null func frames at minimum rate that could help to retain the connection. Signed-off-by: Rajkumar Manoharan <rmanohar@qca.qualcomm.com> Signed-off-by: John W.

To be able to mix with tx_status_irqsafe and rx_irqsafe it also needs to be an "_irqsafe" version in the sense that it goes through the tasklet, the actual flag clearing would be IRQ-safe but doing it directly would cause reordering issues. This is needed in the case of a P2P GO going into an absence period without transmitting any frames that should be driver-released as in this case there's no other way to inform mac80211 that the service period ended. Note that for drivers that don't use the _irqsafe functions another version of this function will be required. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.

| * | | | mac80211: explicitly notify drivers of frame releaseJohannes Berg2011-09-301-0/+17

Before uAPSD, we got by by telling the device that a single frame was going to be released whenever we encountered IEEE80211_TX_CTL_POLL_RESPONSE. With uAPSD, however, that is no longer possible since there could be more than a single frame. To support this model, add a new callback to notify drivers when frames are going to be released.

| * | | | mac80211: reply only once to each PS-pollJohannes Berg2011-09-301-1/+8

As a consequence, the standard asks us to not react to PS-poll frames until the response to one made it out (was ACKed or lost). Implement this by using the WLAN_STA_SP flags to also indicate a PS-Poll "service period" and the IEEE80211_TX_STATUS_EOSP flag for the response packet to indicate the end of the "SP" as usual. We could use separate flags, but that will most likely completely confuse drivers, and while the standard doesn't exclude simultaneously polling using uAPSD and PS-Poll, doing that seems quite problematic.
