2016-01-04mlxsw: spectrum: Change bridge port attributes only when bridgedIdo Schimmel2-6/+14
Bridge port attributes are offloaded to hardware when invoked with SELF flag set, but it really makes no sense to reflect them when port is not bridged. Allow a user to change these attribute only when port is bridged and initialize them correctly when joining or leaving a bridge.

2016-01-04mlxsw: spectrum: Set bridge status in appropriate functionsIdo Schimmel1-10/+5
Set the bridge status of physical ports in the appropriate functions, to be consistent with LAG join/leave and vPorts joining/leaving bridge. Also, remove the error messages in these two functions, as we already emit errors in both the single functions they call.

2016-01-04r8152: add reset_resume functionhayeswang1-1/+9
When the reset_resume() is called, the flag of SELECTIVE_SUSPEND should be cleared and reinitialize the device, whether the SELECTIVE_SUSPEND is set or not. If reset_resume() is called, it means the power supply is cut or the device is reset. That is, the device wouldn't be in runtime suspend state and the reinitialization is necessary.

2016-01-04fsl/fman: allow modular buildArnd Bergmann1-1/+2
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.

Moving the caller of iptunnel_xmit_stats causes a build error in randconfig builds that disable CONFIG_INET: In file included from ../net/xfrm/xfrm_input.c:17:0: ../include/net/ip6_tunnel.h: In function 'ip6tunnel_xmit': ../include/net/ip6_tunnel.h:93:2: error: implicit declaration of function 'iptunnel_xmit_stats' [-Werror=implicit-function-declaration] iptunnel_xmit_stats(dev, pkt_len); The reason is that the iptunnel_xmit_stats definition is hidden inside #ifdef CONFIG_INET but the caller is not.

2016-01-04udp: properly support MSG_PEEK with truncated buffersEric Dumazet2-4/+8
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.

In order to support dedicated or shared completion rings, the ring indexing and mapping are re-structured as below: 1. bp->grp_info[] array index is 1:1 with bp->bnapi[] array index and completion ring index. 2. rx rings 0 to n will be mapped to completion rings 0 to n. 3. 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 Chan2-86/+70
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.

2015-12-31bcma: use module_init for the main part of bus initializationRafał Miłecki1-2/+27
So far we were using fs_initcall. It was (and still is) needed because struct bus_type has to be registered early. However main bus initialization has to happen later as it requires SPROM which depends on NVRAM which depends on mtd. Solve it by using fs_initcall only for bus_register call and module_init for the rest. It affects bcma only when built-in obviously. This was tested with BCM4706 and BCM5357C0 (BCM47XX), BCM4708A0 (ARCH_BCM_5301X) and BCM43225 (PCIe card with bcma as module).

2015-12-30sctp: sctp should release assoc when sctp_make_abort_user return NULL in sctp_closeXin Long2-4/+5
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 Stange1-0/+1
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.

2015-12-30be2net: support ethtool get-dump optionVenkat Duvvuru5-57/+71
This patch adds support for ethtool's --get-dump option in be2net, to retrieve FW dump. 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.

2015-12-30be2net: fix port-res desc query of GET_PROFILE_CONFIG FW cmdSuresh Reddy4-53/+63
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.

This patch removes a line of code that changes adapter->recommended_prio value followed by yet another assignment.

2015-12-30be2net: fix VF link state transition from disabled to autoSuresh Reddy2-10/+28
The VF link state setting transition from "disable" to "auto" does not work due to a bug in SET_LOGICAL_LINK_CONFIG_V1 cmd in FW. This issue could not be fixed in FW due to some backward compatibility issues it causes with some released drivers. The issue has been fixed by introducing a new version (v2) of the cmd from 10.6 FW onwards. In v2, to set the VF link state to auto, both PLINK_ENABLE and PLINK_TRACK bits have to be set to 1. The VF link state setting feature now works on Lancer chips too from FW ver 10.6.315.0 onwards.
