More spring cleaning! The ancient Econet protocol should go. Most of the bug fixes in recent years have been fixing security vulnerabilities. The hardware hasn't been made since the 90s, it is only interesting as an archeological curiosity. For the truly curious, or insomniac, go read up on it. http://en.wikipedia.org/wiki/EconetSigned-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>

The use of the inw/outw functions by the cs89x0 platform driver results in NULL pointer references on ARM platforms and platforms that do not provide ISA-style programmed I/O accessors. Using inw/outw also accesses the wrong address space on platforms that have a PCI I/O space that is not identity-mapped into the physical address space.

The support for CONFIG_MCA is being removed, since the 20 year old hardware simply isn't capable of meeting today's software demands on CPU and memory resources. This commit removes any MCA specific net drivers, and removes any MCA specific probe/support code from drivers that were doing a dual ISA/MCA role. Cc: "David S.

Change the TX ring scheme such that the number of rings for untagged packets and for tagged packets (per each of the vlan priorities) is the same, unlike the current situation where for tagged traffic there's one ring per priority and for untagged rings as the number of core. Queue selection is done as follows: If the mqprio qdisc is operates on the interface, such that the core networking code invoked the device setup_tc ndo callback, a mapping of skb->priority => queue set is forced - for both, tagged and untagged traffic. Else, the egress map skb->priority => User priority is used for tagged traffic, and all untagged traffic is sent through tx rings of UP 0. The patch follows the convergence of discussing that issue with John Fastabend over this thread http://comments.gmane.org/gmane.linux.network/229877 Cc: John Fastabend <john.r.fastabend@intel.com> Cc: Liran Liss <liranl@mellanox.com> Signed-off-by: Amir Vadai <amirv@mellanox.com> Signed-off-by: David S.

When I first wrote drop monitor I wrote it to just build monolithically. There is no reason it can't be built modularly as well, so lets give it that flexibiity. I've tested this by building it as both a module and monolithically, and it seems to work quite well Change notes: v2) * fixed for_each_present_cpu loops to be more correct as per Eric D. * Converted exit path failures to BUG_ON as per Ben H. v3) * Converted del_timer to del_timer_sync to close race noted by Ben H.

netdev_alloc_skb() is used by networks driver in their RX path to allocate an skb to receive an incoming frame. With recent skb->head_frag infrastructure, it makes sense to change netdev_alloc_skb() to use build_skb() and a frag allocator. This permits a zero copy splice(socket->pipe), and better GRO or TCP coalescing. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Under certain scenarios, it's possible that bursty manageability traffic over the BMC-to-OS path may overrun the internal manageability receive buffer causing dropped manageability packets. Clearing this bit prevents this situation by interrupting coalescing to allow manageability traffic through.

The code seems to want to look at the last byte where the HW puts some information. Since the skb->data area is never seen by the HW I guess it does not work as expected. We pass the page address to the HW so I *think* in order to get to the last byte where the information might be one should use the page buffer and take a look. This is of course not more than just compile tested.

Sebastian Andrzej Siewior authored
According to the comment, errata 23 says that the memory we allocate can't cross a 64KiB boundary. In case of jumbo frames we allocate complete pages which can never cross the 64KiB boundary because PAGE_SIZE should be a multiple of 64KiB so we stop either before the boundary or start after it but never cross it. Furthermore the check seems bogus because it looks at skb->data which is not seen by the HW at all because we only pass the DMA address of the page we allocated. So I *think* the workaround is not required here.

Pull networking tree from David Miller: 1) ptp_pch driver build broke during this merge window due to missing slab.h header, fix from Geery Uytterhoeven. 2) If ipset passes in a bogus hash table size we crash because the size is not validated properly. Compounding this, gcc-4.7 can miscompile ipset such that even when the user specifies legitimate parameters the tool passes in an out-of-range size to the kernel. Fix from Jozsef Kadlecsik. 3) Users have reported that the netdev watchdog can trigger with pch_gbe devices, and it turns out this is happening because of races in the TX path of the driver leading to the transmitter hanging. Fix from Eric Dumazet, reported and tested by Andy Cress. 4) Novatel USB551L devices match the generic class entries for the cdc ethernet USB driver, but they don't work because they have generic descriptors and thus need FLAG_WWAN to function properly. Add the necessary ID table entry to fix this, from Dan Williams. 5) A recursive locking fix in the USBNET driver added a new problem, in that packet list traversal is now racy and we can thus access unlinked SKBs and crash. Avoid this situation by adding some extra state tracking, from Ming Lei. 6) The rtlwifi conversion to asynchronous firmware loading is racy, fix by reordering the probe procedure. From Larry Finger. Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=43187 7) Fix regressions with bluetooth keyboards by notifying userland properly when the security level changes, from Gustavo Padovan. 8) Bluetooth needs to make sure device connected events are emitted before other kinds of events, otherwise userspace will think there is no baseband link yet and therefore abort the sockets associated with that connection. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: netfilter: ipset: fix hash size checking in kernel ptp_pch: Add missing #include <linux/slab.h> pch_gbe: fix transmit races cdc_ether: add Novatel USB551L device IDs for FLAG_WWAN usbnet: fix skb traversing races during unlink(v2) Bluetooth: mgmt: Fix device_connected sending order Bluetooth: notify userspace of security level change rtlwifi: fix for race condition when firmware is cached
