2016-01-04soreuseport: setsockopt SO_ATTACH_REUSEPORT_[CE]BPFCraig Gallek
Expose socket options for setting a classic or extended BPF program for use when selecting sockets in an SO_REUSEPORT group. These options can be used on the first socket to belong to a group before bind or on any socket in the group after bind. This change includes refactoring of the existing sk_filter code to allow reuse of the existing BPF filter validation checks.

2016-01-04soreuseport: fast reuseport UDP socket selectionCraig Gallek
Include a struct sock_reuseport instance when a UDP socket binds to a specific address for the first time with the reuseport flag set. When selecting a socket for an incoming UDP packet, use the information available in sock_reuseport if present. This required adding an additional field to the UDP source address equality function to differentiate between exact and wildcard matches. The original use case allowed wildcard matches when checking for existing port uses during bind. The new use case of adding a socket to a reuseport group requires exact address matching. Performance test (using a machine with 2 CPU sockets and a total of 48 cores): Create reuseport groups of varying size. Use one socket from this group per user thread (pinning each thread to a different core) calling recvmmsg in a tight loop. Record number of messages received per second while saturating a 10G link. 10 sockets: 18% increase (~2.8M -> 3.3M pkts/s) 20 sockets: 14% increase (~2.9M -> 3.3M pkts/s) 40 sockets: 13% increase (~3.0M -> 3.4M pkts/s) This work is based off a similar implementation written by Ying Cai <ycai@google.com> for implementing policy-based reuseport selection.

2016-01-04soreuseport: define reuseport groupsCraig Gallek
struct sock_reuseport is an optional shared structure referenced by each socket belonging to a reuseport group. When a socket is bound to an address/port not yet in use and the reuseport flag has been set, the structure will be allocated and attached to the newly bound socket. When subsequent calls to bind are made for the same address/port, the shared structure will be updated to include the new socket and the newly bound socket will reference the group structure. Usually, when an incoming packet was destined for a reuseport group, all sockets in the same group needed to be considered before a dispatching decision was made. With this structure, an appropriate socket can be found after looking up just one socket in the group. This shared structure will also allow for more complicated decisions to be made when selecting a socket (eg a BPF filter). This work is based off a similar implementation written by Ying Cai <ycai@google.com> for implementing policy-based reuseport selection.

2016-01-04fsl/fman: allow modular buildArnd Bergmann
ARM allmodconfig fails because of the addition of the FMAN driver: drivers/built-in.o: In function `dtsec_restart_autoneg': binder.c:(.text+0x173328): undefined reference to `mdiobus_read' binder.c:(.text+0x173348): undefined reference to `mdiobus_write' drivers/built-in.o: In function `dtsec_config': binder.c:(.text+0x173d24): undefined reference to `of_phy_find_device' drivers/built-in.o: In function `init_phy': binder.c:(.text+0x1763b0): undefined reference to `of_phy_connect' drivers/built-in.o: In function `stop': binder.c:(.text+0x176014): undefined reference to `phy_stop' drivers/built-in.o: In function `start': binder.c:(.text+0x176078): undefined reference to `phy_start' The reason is that the driver uses PHYLIB, but that is a loadable module here, and fman itself is built-in. This patch makes it possible to configure fman as a module as well so we don't change the status of PHYLIB in an allmodconfig kernel, and it adds a 'select PHYLIB' statement to ensure that phylib is always built-in when fman is. The driver uses "builtin_platform_driver(fman_driver);", which means it cannot be unloaded, but it's still possible to have it as a loadable module that gets loaded once and never removed.

2016-01-04udp: properly support MSG_PEEK with truncated buffersEric Dumazet
Backport of this upstream commit into stable kernels : 89c22d8c3b27 ("net: Fix skb csum races when peeking") exposed a bug in udp stack vs MSG_PEEK support, when user provides a buffer smaller than skb payload. In this case, skb_copy_and_csum_datagram_iovec(skb, sizeof(struct udphdr), msg->msg_iov); returns -EFAULT. This bug does not happen in upstream kernels since Al Viro did a great job to replace this into : skb_copy_and_csum_datagram_msg(skb, sizeof(struct udphdr), msg); This variant is safe vs short buffers. For the time being, instead reverting Herbert Xu patch and add back skb->ip_summed invalid changes, simply store the result of udp_lib_checksum_complete() so that we avoid computing the checksum a second time, and avoid the problematic skb_copy_and_csum_datagram_iovec() call. This patch can be applied on recent kernels as it avoids a double checksumming, then backported to stable kernels as a bug fix.

The driver has to process the completion ring entries sequentially for the events. The current code only supports an rx/tx ring pair for each completion ring. This patch series add support for using a dedicated completion ring for rx only or tx only as an option configuarble using ethtool -L. The benefits for using dedicated completion rings are: 1. A burst of rx packets can cause delay in processing tx events if the completion ring is shared. If tx queue is stopped by BQL, this can cause delay in re-starting the tx queue. 2. A completion ring is sized according to the rx and tx ring size rounded up to the nearest power of 2. When the completion ring is shared, it is sized by adding the rx and tx ring sizes and then rounded to the next power of 2, often with a lot of wasted space. 3. Using dedicated completion ring, we can adjust the tx and rx coalescing parameters independently for rx and tx. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

If tx and rx rings share completion rings, then tx rings 0 to m will be mapped to completion rings 0 to m. 4. If tx and rx rings use dedicated completion rings, then tx rings 0 to m will be mapped to completion rings n + 1 to n + m. 5.

2016-01-04bnxt_en: Separate bnxt_{rx|tx}_ring_info structs from bnxt_napi struct.Michael Chan
Currently, an rx and a tx ring are always paired with a completion ring. We want to restructure it so that it is possible to have a dedicated completion ring for tx or rx only. The bnxt hardware uses a completion ring for rx and tx events. The driver has to process the completion ring entries sequentially for the rx and tx events. Using a dedicated completion ring for rx only or tx only has these benefits: 1. A burst of rx packets can cause delay in processing tx events if the completion ring is shared. If tx queue is stopped by BQL, this can cause delay in re-starting the tx queue. 2. A completion ring is sized according to the rx and tx ring size rounded up to the nearest power of 2. When the completion ring is shared, it is sized by adding the rx and tx ring sizes and then rounded to the next power of 2, often with a lot of wasted space. 3. Using dedicated completion ring, we can adjust the tx and rx coalescing parameters independently for rx and tx. The first step is to separate the rx and tx ring structures from the bnxt_napi struct. In this patch, an rx ring and a tx ring will point to the same bnxt_napi struct to share the same completion ring. No change in ring assignment and mapping yet.

2015-12-30sctp: sctp should release assoc when sctp_make_abort_user return NULL in ↵Xin Long
sctp_close In sctp_close, sctp_make_abort_user may return NULL because of memory allocation failure. If this happens, it will bypass any state change and never free the assoc. The assoc has no chance to be freed and it will be kept in memory with the state it had even after the socket is closed by sctp_close(). So if sctp_make_abort_user fails to allocate memory, we should abort the asoc via sctp_primitive_ABORT as well. Just like the annotation in sctp_sf_cookie_wait_prm_abort and sctp_sf_do_9_1_prm_abort said, "Even if we can't send the ABORT due to low memory delete the TCB. This is a departure from our typical NOMEM handling". But then the chunk is NULL (low memory) and the SCTP_CMD_REPLY cmd would dereference the chunk pointer, and system crash. So we should add SCTP_CMD_REPLY cmd only when the chunk is not NULL, just like other places where it adds SCTP_CMD_REPLY cmd.

2015-12-30net, socket, socket_wq: fix missing initialization of flagsNicolai Stange
Commit ceb5d58b2170 ("net: fix sock_wake_async() rcu protection") from the current 4.4 release cycle introduced a new flags member in struct socket_wq and moved SOCKWQ_ASYNC_NOSPACE and SOCKWQ_ASYNC_WAITDATA from struct socket's flags member into that new place. Unfortunately, the new flags field is never initialized properly, at least not for the struct socket_wq instance created in sock_alloc_inode(). One particular issue I encountered because of this is that my GNU Emacs failed to draw anything on my desktop -- i.e. what I got is a transparent window, including the title bar. Bisection lead to the commit mentioned above and further investigation by means of strace told me that Emacs is indeed speaking to my Xorg through an O_ASYNC AF_UNIX socket. This is reproducible 100% of times and the fact that properly initializing the struct socket_wq ->flags fixes the issue leads me to the conclusion that somehow SOCKWQ_ASYNC_WAITDATA got set in the uninitialized ->flags, preventing my Emacs from receiving any SIGIO's due to data becoming available and it got stuck. Make sock_alloc_inode() set the newly created struct socket_wq's ->flags member to zero.

William Dauchy provides a fix for ixgbevf that was implemented for ixgbe, commit 5d6002b7b822c7 ("ixgbe: Fix handling of NAPI budget when multiple queues are enabled per vector"). The issue was that the polling routine would increase the budget for receive to at least 1 per queue if multiple queues were present, which resulted in receive packets being processed when the budget was 0. Emil provides minor cleanups for ixgbevf, one being that we need to check rx_itr_setting with == and not &, since it is not a mask. Added QSFP PHY support in ixgbe to allow for more accurate reporting of port settings. Fixed the max RSS limit for X550 which is 63, not 64. Veola fixes ixgbe ethtool reporting of backplane type interfaces as 1000/10000baseT link modes, instead, report the media as KR, KX or KX4 based on the backplane interface present. Mark cleans up redundancy in the setting of hw_enc_features that makes it appear that X550 has more encapsulation features than other devices. Also do not set NETIF_F_SG any longer since that is set by the register_netdev() call. Also fixed the X550EM_x revision check, which needs to check a value, not just a bit. Alex Duyck fixes additional bugs in ixgbe_clear_vf_vlans(), one being that the mask was using a divide instead of a modulus, which resulted in the mask bit being incorrectly set to 0 or 1 based on the value of the VF being tested. Alex also found that he was not consistent in using the "word" argument as an offset or as a register offset, so made the code consistently use word as the offset in the array. v2: dropped patch 8 of the original series, as it was undoing a part of the fix Alex Duyck was doing in patch 9 of the original series. Dropped based on feedback from Emil (the author). ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Sathya Perla says: ==================== be2net: patch set The following patch set contains some feature additions, code re-organization and cleanup and a few non-critical fixes. Pls consider applying this to the net-next tree. Thanks. v3 changes: add a default case to the switch statement in patch 5 to satisfy the compiler (-Wswitch). v2 changes: replaced an if/else block that checks for error values with a switch/case statement in patch 5. Patch 1 fixes VF link state transition from disabled to auto that did not work due to an issue in the FW. This issue could not be fixed in FW due to some backward compatibility issues it causes with released drivers. The issue has been fixed by introducing a new version (v2) of the cmd from 10.6 FW onwards. This patch adds support for v2 version of this cmd. Patch 2 reports a EOPNOTSUPP status to ethtool when the user tries to configure BE3/SRIOV in VEPA mode as it is not supported by the chip. Patch 3 cleansup FW flash image related constant definitions. Many of these definitions (such as section offset values) were defined in decimal format rather than hexa-decimal. This makes this part of the code un-readable. Also some defines related to BE2 are labeld "g2" and defines related to BE3 are labeled "g3". This patch cleans up all of this to make this code more readable. Patch 4 moves the FW cmd code to be_cmds.c. All code relating to FW cmds has been in be_cmds.[ch], excepting FW flash cmd related code. This patch moves these routines from be_main.c to be_cmds.c. Patch 5 adds a log message to report digital signature errors while flashing a FW image. From FW version 11.0 onwards, the FW supports a new "secure mode" feature (based on a jumper setting on the adapter.) In this mode, the FW image when flashed is authenticated with a digital signature. Patch 6 removes a line of code that has no effect. Patch 7 removes some unused variables. Patch 8 fixes port resource descriptor query via the GET_PROFILE FW cmd. An earlier commit passed a specific pf_num while issuing this cmd as FW returns descriptors for all functions when pf_num is zero. But, when pf_num is set to a non-zero value, FW does not return the port resource descriptor. This patch fixes this by setting pf_num to 0 while issuing the query cmd and adds code to pick the correct NIC resource descriptor from the list of descriptors returned by FW. Patch 9 adds support for ethtool get-dump feature. In the past when this option was not yet available, this feature was supported via the --register-dump option as a workaround. This patch removes support for FW-dump via --register-dump option as it is now available via --get-dump option. Even though the "ethtool --register-dump" cmd which used to work earlier, will now fail with ENOTSUPP error, we feel it is not an issue as this is used only for diagnostics purpose. Patch 10 bumps up the driver version. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2015-12-30be2net: fix port-res desc query of GET_PROFILE_CONFIG FW cmdSuresh Reddy
Commit 72ef3a88fa8e ("be2net: set pci_func_num while issuing GET_PROFILE_CONFIG cmd") passed a specific pf_num while issuing a GET_PROFILE_CONFIG cmd as FW returns descriptors for all functions when pf_num is zero. But, when pf_num is set to a non-zero value, FW does not return the Port resource descriptor. This patch fixes this by setting pf_num to 0 while issuing the query cmd and adds code to pick the correct NIC resource descriptor from the list of descriptors returned by FW.
