2013-02-28tcp: avoid wakeups for pure ACKEric Dumazet
TCP prequeue mechanism purpose is to let incoming packets being processed by the thread currently blocked in tcp_recvmsg(), instead of behalf of the softirq handler, to better adapt flow control on receiver host capacity to schedule the consumer. But in typical request/answer workloads, we send request, then block to receive the answer. And before the actual answer, TCP stack receives the ACK packets acknowledging the request. Processing pure ACK on behalf of the thread blocked in tcp_recvmsg() is a waste of resources, as thread has to immediately sleep again because it got no payload. This patch avoids the extra context switches and scheduler overhead.

2013-02-28Merge branch 'sctp'David S. Miller
Lee A. Roberts says: ==================== This series of patches resolves several SCTP association hangs observed during SCTP stress testing. Observable symptoms include communications hangs with data being held in the association reassembly and/or lobby (ordering) queues. Close examination of reassembly/ordering queues may show either duplicated or missing packets. In version #2, corrected build failure in initial version of patch series due to wrong calling sequence for sctp_ulpq_partial_delivery() being inserted in sctp_ulpq_renege(). In version #3, adjusted patch documentation to be less repetitive. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2013-02-28sctp: fix association hangs due to partial delivery errorsLee A. Roberts
In sctp_ulpq_tail_data(), use return values 0,1 to indicate whether a complete event (with MSG_EOR set) was delivered. A return value of -ENOMEM continues to indicate an out-of-memory condition was encountered. In sctp_ulpq_retrieve_partial() and sctp_ulpq_retrieve_first(), correct message reassembly logic for SCTP partial delivery. Change logic to ensure that as much data as possible is sent with the initial partial delivery and that following partial deliveries contain all available data. In sctp_ulpq_partial_delivery(), attempt partial delivery only if the data on the head of the reassembly queue is at or before the cumulative TSN ACK point. In sctp_ulpq_renege(), use the modified return values from sctp_ulpq_tail_data() to choose whether to attempt partial delivery or to attempt to drain the reassembly queue as a means to reduce memory pressure. Remove call to sctp_tsnmap_mark(), as this is handled correctly in call to sctp_ulpq_tail_data(). Signed-off-by: Lee A.

In sctp_tsnmap_mark(), correct off-by-one error when calculating size value for sctp_tsnmap_grow(). In sctp_tsnmap_grow(), correct off-by-one error when copying and resizing the tsnmap. If max_tsn_seen is in the LSB of the word, this bit can be lost, causing the corresponding packet to be transmitted again and to be entered as a duplicate into the SCTP reassembly/ordering queues.

2013-02-27usb/net/asix_devices: Add USBNET HG20F9 ethernet dongleGlen Turner
This USB ethernet adapter was purchased in anodyne packaging from the computer store adjacent to linux.conf.au 2013 in Canberra (Australia). A web search shows other recent purchasers in Lancaster (UK) and Seattle (USA). Just like an emergent virus, our age of e-commerce and airmail allows underdocumented hardware to spread around the world instantly using the vector of ridiculously low prices. Paige Thompson, infected via eBay, discovered that the HG20F9 is a copy of the Asix 88772B; many viruses copy the RNA of other viruses. See Paige's work at <https://github.com/paigeadele/HG20F9>. This patch uses her discovery to update the restructured Asix driver in the current kernel. Just as some viruses inhabit seemingly-healthy cells, the HG20F9 uses the Vendor ID 0x066b assigned to Linksys Inc. For the present there is no clash of Product ID 0x20f9.

2013-02-26sfc: Detach net device when stopping queues for reconfigurationBen Hutchings
We must only ever stop TX queues when they are full or the net device is not 'ready' so far as the net core, and specifically the watchdog, is concerned. Otherwise, the watchdog may fire *immediately* if no packets have been added to the queue in the last 5 seconds. The device is ready if all the following are true: (a) It has a qdisc (b) It is marked present (c) It is running (d) The link is reported up (a) and (c) are normally true, and must not be changed by a driver. (d) is under our control, but fake link changes may disturb userland. This leaves (b). We already mark the device absent during reset and self-test, but we need to do the same during MTU changes and ring reallocation. We don't need to do this when the device is brought down because then (c) is already false. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
2013-02-26sfc: Fix efx_rx_buf_offset() in the presence of swiotlbBen Hutchings
We assume that the mapping between DMA and virtual addresses is done on whole pages, so we can find the page offset of an RX buffer using the lower bits of the DMA address. However, swiotlb maps in units of 2K, breaking this assumption. Add an explicit page_offset field to struct efx_rx_buffer. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
2013-02-26sfc: Properly sync RX DMA buffer when it is not the last in the pageBen Hutchings
We may currently allocate two RX DMA buffers to a page, and only unmap the page when the second is completed. We do not sync the first RX buffer to be completed; this can result in packet loss or corruption if the last RX buffer completed in a NAPI poll is the first in a page and is not DMA-coherent. (In the middle of a NAPI poll, we will handle the following RX completion and unmap the page *before* looking at the content of the first buffer.)

I do my best to document that if you care about limiting your unprivileged users that when you have the user namespace support enabled you will need to enable memory control groups. There is a minor bug fix to prevent overflowing the stack if someone creates way too many user namespaces. The bulk of the changes are a continuation of the kuid/kgid push down work through the filesystems. These changes make using uids and gids typesafe which ensures that these filesystems are safe to use when multiple user namespaces are in use. The filesystems converted for 3.9 are ceph, 9p, afs, ocfs2, gfs2, ncpfs, nfs, nfsd, and cifs. The changes for these filesystems were a little more involved so I split the changes into smaller hopefully obviously correct changes. XFS is the only filesystem that remains. I was hoping I could get that in this release so that user namespace support would be enabled with an allyesconfig or an allmodconfig but it looks like the xfs changes need another couple of days before it they are ready." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (93 commits) cifs: Enable building with user namespaces enabled. cifs: Convert struct cifs_ses to use a kuid_t and a kgid_t cifs: Convert struct cifs_sb_info to use kuids and kgids cifs: Modify struct smb_vol to use kuids and kgids cifs: Convert struct cifsFileInfo to use a kuid cifs: Convert struct cifs_fattr to use kuid and kgids cifs: Convert struct tcon_link to use a kuid. cifs: Modify struct cifs_unix_set_info_args to hold a kuid_t and a kgid_t cifs: Convert from a kuid before printing current_fsuid cifs: Use kuids and kgids SID to uid/gid mapping cifs: Pass GLOBAL_ROOT_UID and GLOBAL_ROOT_GID to keyring_alloc cifs: Use BUILD_BUG_ON to validate uids and gids are the same size cifs: Override unmappable incoming uids and gids nfsd: Enable building with user namespaces enabled. nfsd: Properly compare and initialize kuids and kgids nfsd: Store ex_anon_uid and ex_anon_gid as kuids and kgids nfsd: Modify nfsd4_cb_sec to use kuids and kgids nfsd: Handle kuids and kgids in the nfs4acl to posix_acl conversion nfsd: Convert nfsxdr to use kuids and kgids nfsd: Convert nfs3xdr to use kuids and kgids ...
