mfc_mcastgrp and mfc_origin are __be32, thus we need to convert INADDR_ANY. Because INADDR_ANY is 0, this patch just fix sparse warnings. Reported-by:

Delete successive tests to the same location. rc was previously tested and not subsequently updated. efx_phc_adjtime can return an error code, so the call is updated so that is tested instead. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @s exists@ local idexpression y; expression x,e; @@ *if ( \(x == NULL\|IS_ERR(x)\|y != 0\) ) { ... when forall return ...; } ... when != \(y = e\|y += e\|y -= e\|y |= e\|y &= e\|y++\|y--\|&y\) when != \(XT_GETPAGE(...,y)\|WMI_CMD_BUF(...)\) *if ( \(x == NULL\|IS_ERR(x)\|y != 0\) ) { ... when forall return ...; } // </smpl> Signed-off-by:

The slave MII bus registered by the DSA code is using the parent MII bus as part of its name (ds->master_mii_bus_id), in case the parent MII bus name is already 16 characters long (such as d0072004.mdio-mi) we will get the following WARN_ON in dsa_switch_setup() when calling mdiobus_register(): [ 79.088782] ------------[ cut here ]------------ [ 79.093448] WARNING: at fs/sysfs/dir.c:536 sysfs_add_one+0x80/0xa0() [ 79.099831] sysfs: cannot create duplicate filename '/class/mdio_bus/d0072004.mdio-mi' This is a genuine warning, because the DSA slave MII bus will also be named d0072004.mdio-mi, and since MII_BUS_ID_SIZE is 17 characters long (with null-terminator) the following will truncate the slave MII bus id: snprintf(ds->slave_mii_bus->id, MII_BUS_ID_SIZE, "%s-%d:%.2x", ds->master_mii_bus->id, ds->pd->sw_addr); Fix this by using dsa-<switch index->:<sw_add> which is guaranteed to be unique.

Currently we write MAC address to pci config space byte by byte, this means that we have an intermediate step where mac is wrong. This patch introduced a new control command to set MAC address, it's atomic. VIRTIO_NET_F_CTRL_MAC_ADDR is a new feature bit for compatibility. Signed-off-by:

When we set mac address, software mac address in system and hardware mac address all need to be updated. Current eth_mac_addr() doesn't allow callers to implement error handling nicely. This patch split eth_mac_addr() to prepare part and real commit part, then we can prepare first, and try to change hardware address, then do the real commit if hardware address is set successfully.

Nicolas Dichtel says: ==================== The goal of this serie is to add the support of proxy multicast, ie being able to build a static multicast tree. In other words, it adds the support of (*,G) mf[6]c entries. v2: use INADDR_ANY instead of 0 for IPv4 addresses ==================== Signed-off-by: -
Nicolas Dichtel authored
This patch add the support of proxy multicast, ie being able to build a static multicast tree. It adds the support of (*,*) and (*,G) entries. The user should define an (*,*) entry which is not used for real forwarding. This entry defines the upstream in iif and contains all interfaces from the static tree in its oifs. It will be used to forward packet upstream when they come from an interface belonging to the static tree. Hence, the user should define (*,G) entries to build its static tree. Note that upstream interface must be part of oifs: packets are sent to all oifs interfaces except the input interface. This ensures to always join the whole static tree, even if the packet is not coming from the upstream interface. Signed-off-by:

The original intent of this file was to list limitations in drivers/hardware relating to multicast use, back when some modest hardware from the early 1990s did not support things we might take for granted today. I was intending to delete some now-gone MCA/token ring entries in this file, but once I opened it, I found it only contained information on the earliest (pre-2000) linux networking drivers. Checking the git history shows that the file hasn't been touched since 2005. Clearly nobody is actively consulting this file as a meaningful reference. Rather than add a "YES YES YES" line for all of the drivers we currently have, lets just take advantage of the fact that nobody is using the file to delete it. This has the side benefit of not having to do a line-by-line deletion of the file content as each older driver is expired. Signed-off-by:

Commit 46d3ceab "tcp: TCP Small Queues" has severly degraded performance for single connection RR workloads on HiperSockets with MTU >=16K due to a conflict of the TCP Small Queues approach with our buffer scan threshold which releases buffers not frequently enough yet.

As of now, s390dbf entries for the cards are discarded as soon as the device is removed. However, this will also bar us of all chances of getting valuable debug information after a device has been removed. This patch will keep the s390dbf entries around until the qeth module is removed.

The existing port isolation mode 'forward' will now verify that the adjacent switch port supports the required reflective relay (RR) mode. This patch adds the required error handling for the cases where enabling port isolation mode 'forward' can now fail. Furthermore, once established, we never fall back from one of the port isolation modes to a non-isolated mode without further user-interaction. This includes cases where the isolation mode was enabled successfully, but ceases to work e.g. due to configuration changes at the switch port. Finally, configuring an isolation mode with the device being offline will make onlining the device fail permanently upon errors encountered until either errors are resolved or the isolation mode is changed by the user to a different mode.

YOSHIFUJI Hideaki says: ==================== This series of changes basically clean up NDISC logic, especially on sender side. We originally do For NS/NA/RS: 1) build temporary ICMPv6 header 2) ndisc_build_skb() with temporary ICMPv6 header and rather criptic arguments. - Calculate total length and allocate sk_buff - Build IPv6 header. - copy ICMPv6 header, additional data and ND options. - Fill-in ICMPv6 checksum. Here, structures defined for message format was not used at all, it is difficult to understand what is being sent, and it was not generic. 3) __ndisc_send() - Allocate temporary dst. - Send it. Several issues: - We could not defer decision if we should/can send some ND option. - It is hard to see the packet format at a glance. - ICMPv6 header was built as temporary variable, and then copied to the buffer. - Some code path for Redirect was not shared. With these patches, we do: 1) Calculate (or estimate) message length and option length. 2) Allocate skb (via new ndisc_skb_alloc()). 3) Fill-in ICMPv6 message directly using compound literals. 4) Fill-in ICMPv6 checksum 5) Build IPv6 header (including length) 6) Send the packet (via ndisc_send_skb()). - allocate temporary dst and send it. - We can defer calculating real length of the packet. For example, we can give up filling some option at when filling in. - Message is built directly without temporary buffer. - Structures defined for message format is easier to understand what is being built. - NS/NA/RS/Redirect share same logic. - Reduced code/data size: text data bss dec hex filename 265407 14133 3488 283028 45194 old/net/ipv6/ipv6.o 264955 14109 3488 282552 44fb8 new/net/ipv6/ipv6.o ==================== Signed-off-by: -
