The driver was being called by VLAN, bonding, teaming operations that expected to be able to hold locks like rcu_read_lock(). This causes the driver to be held to the requirement to not sleep, and was found by the kernel debug options for checking sleep inside critical section, and the locking validator.

Instead of awkwardly keeping a fixed array of pointers in the adapter struct and then allocating ring structs individually, just keep a single pointer and allocate a single blob for the arrays. This simplifies code, shrinks the adapter structure, and future-proofs the driver by not limiting the number of rings we can handle.

Change the queue_vector array from a statically-sized member of the adapter structure to a dynamically-allocated and -sized array. This reduces the size of the adapter structure, and allows us to support any number of queue vectors in the future without changing the code.

If, upon a midnight dreary, the PF returns ERR_PARAM when the VF is requesting resources, that's fatal. Either the firmware or NVM is badly, badly misconfigured, or this VF has been disabled due to a previous VF driver sending a bunch of bogus messages. Either way, there is no recovery from this. Don't ponder weak and weary, just quit. Change-ID: I09d9f16cc4ee7fec3b57646a289d33838c1c5bf5 Signed-off-by:

If we get an invalid message from a VF, we should tell the user which VF is being naughty, rather than making them guess. Change-ID: I9252cef7baea3d8584043ed6ff12619a94e2f99c Signed-off-by:

This patch fixes the confusing kernel message of enabled RSS size, by reporting it together with the hardware maximum RSS size. Change-ID: I64864dbfbc13beccc180a7871680def1f3d5a339 Signed-off-by:

This patch fixes an issue where adminq init failures always provided a message that NVM was newer than expected. This is not always the case for init_adminq failures. Without this patch, if adminq init fails for any reason, newer NVM message would be given. This problem is fixed by adding a check for that specific error condition and a different hopefully helpful message otherwise. Change-ID: Iaeaebee4e398989eae40bb70f943ab66a3a521a5 Signed-off-by:

This patch fixes the issue of forcing WB too often causing us to not benefit from NAPI. Without this patch we were forcing WB/arming interrupt too often taking away the benefits of NAPI and causing a performance impact. With this patch we disable force WB in the clean routine for X710 and XL710 adapters. X722 adapters do not enable interrupt to force a WB and benefit from WB_ON_ITR and hence force WB is left enabled for those adapters. For XL710 and X710 adapters if we have less than 4 packets pending a software Interrupt triggered from service task will force a WB. This patch also changes the conditions for setting RS bit as described in code comments. This optimizes when the HW does a tail bump amd when it does a WB. It also optimizes when we do a wmb.

The 'sc' ISDN driver relies on using readl() to access ISA I/O memory. This has been deprecated and produced warnings since linux-2.3.23, disabled by default since 2.4.10 and finally removed in 2.6.5. I found this because the compiling the driver for ARM produces a warning: In file included from ../drivers/isdn/sc/includes.h:8:0, from ../drivers/isdn/sc/init.c:13: ../arch/arm/include/asm/io.h:115:21: note: expected 'const volatile void *' but argument is of type 'long unsigned int' It is pretty clear that this driver has not been used for a long time and there is no point fixing it now, so let's remove it.

This module allows to insert errors in some of netdevice's notifier events. All network drivers use these notifiers to signal various events and to check if they are allowed, e.g. PRECHANGEMTU and CHANGEMTU afterwards. Until recently I had to run failure tests by injecting a custom module, but now this infrastructure makes it trivial to test these failure paths. Some of the recent bugs I fixed were found using this module. Here's an example: $ cd /sys/kernel/debug/notifier-error-inject/netdev $ echo -22 > actions/NETDEV_CHANGEMTU/error $ ip link set eth0 mtu 1024 RTNETLINK answers: Invalid argument CC: Akinobu Mita <akinobu.mita@gmail.com> CC: "David S.

There are several issues in hv_netvsc driver with regards to link status change handling: - RNDIS_STATUS_NETWORK_CHANGE results in calling userspace helper doing '/etc/init.d/network restart' and this is inappropriate and broken for many reasons. - link_watch infrastructure only sends one notification per second and in case of e.g. paired disconnect/connect events we get only one notification with last status. This makes it impossible to handle such situations in userspace. Redo link status changes handling in the following way: - Create a list of reconfig events in network device context. - On a reconfig event add it to the list of events and schedule netvsc_link_change(). - In netvsc_link_change() ensure 2-second delay between link status changes. - Handle RNDIS_STATUS_NETWORK_CHANGE as a paired disconnect/connect event.

The current unix_dgram_recvmsg does a wake up for every received datagram. This seems wasteful as only SOCK_DGRAM client sockets in an n:1 association with a server socket will ever wait because of the associated condition. The patch below changes the function such that the wake up only happens if wq_has_sleeper indicates that someone actually wants to be notified. Testing with SOCK_SEQPACKET and SOCK_DGRAM socket seems to confirm that this is an improvment. Signed-Off-By:

Nikolay Aleksandrov says: ==================== net: ipmr: more cleanups and mfc netlink support This set continues with the minor cleanups in the first 6 patches and patch 7 adds the first new feature - MFC manipulation via netlink. It registers NEWROUTE/DELROUTE for that purpose and uses the same semantics as the already present netlink dump. The only new attribute that is used is RTA_PREFSRC to denote an MFC_PROXY entry. Currently the table must exist before adding an entry, and new tables can be created only via setsockopt, but that will be changed in the future. This set was tested with modified iproute2 which supports NEWROUTE/DELROUTE for RTNL_FAMILY_IPMR. ==================== Signed-off-by: -

This patch adds support to add and remove MFC entries. It uses the same attributes like the already present dump support in order to be consistent. There's one new entry - RTA_PREFSRC, it's used to denote an MFC_PROXY entry (see MRT_ADD_MFC vs MRT_ADD_MFC_PROXY). The already existing infrastructure is used to create and delete the entries, the netlink message gets converted internally to a struct mfcctl which is used with ipmr_mfc_add/delete. The other used attributes are: RTA_IIF - used for mfcc_parent (when adding it's required to be valid) RTA_SRC - used for mfcc_origin RTA_DST - used for mfcc_mcastgrp RTA_TABLE - the MRT table id RTA_MULTIPATH - the "oifs" ttl array Signed-off-by:
