Define special location values for RX NFC that request the driver to select the actual rule location. This allows for implementation on devices that use hash-based filter lookup, whereas currently the API is more suited to devices with TCAM lookup or linear search. In ethtool_set_rxnfc() and the compat wrapper ethtool_ioctl(), copy the structure back to user-space after insertion so that the actual location is returned.

SMSC LAN generation 4 chips integrate an IEEE 802.3 ethernet physical layer. The PHY driver for this integrated chip enable an energy detect power-down mode. When the PHY is in a power-down mode, it prevents the MAC portion chip to be software reseted. That means that if we compile the kernel with the configuration option SMSC_PHY enabled and try to bring the network interface up without an cable plug-ed the PHY will be in a low power mode and the software reset will fail returning -EIO to user-space: root@igep00x0:~# ifconfig eth0 up ifconfig: SIOCSIFFLAGS: Input/output error This patch disable the energy detect power-down mode before trying to software reset the LAN chip and re-enables after it was reseted successfully.

SMSC generation 4 LAN chips integrate an IEEE 802.3 ethernet physical layer. The ethernet driver for this family of devices needs to access the SMSC PHY registers and bit-fields.

The driver uses a shared pool for both rx and tx descriptors. During open it queues fixed number of 128 descriptors for receive packets. For each received packet it tries to queue another descriptor. If this fails the descriptor is lost for rx. The driver has no limitation on tx descriptors to use, so it can happen during a nmap / ping -f attack that the driver allocates all descriptors for tx and looses all rx descriptors. The driver stops working then. To fix this limit the number of tx descriptors used to half of the descriptors available, the rx path uses the other half. Tested on a custom board using nmap / ping -f to the board from two different hosts. Signed-off-by: NSascha Hauer <s.hauer@pengutronix.de> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

SFQ enqueue algo puts a new flow _behind_ all pre-existing flows in the circular list. In fact this is probably an old SFQ implementation bug. 100 Mbits = ~8333 full frames per second, or ~8 frames per ms. With 50 flows, it means your "new flow" will have to wait 50 packets being sent before its own packet. Thats the ~6ms. We certainly can change SFQ to give a priority advantage to new flows, so that next dequeued packet is taken from a new flow, not an old one.

If slave device already has a receive handler registered, then the error unwind of bonding device enslave function is broken. The following will leave a pointer to freed memory in the slave device list, causing a later kernel panic. # modprobe dummy # ip li add dummy0-1 link dummy0 type macvlan # modprobe bonding # echo +dummy0 >/sys/class/net/bond0/bonding/slaves The fix is to detach the slave (which removes it from the list) in the unwind path.

It was found (by Sasha) that if you use a futex located in the gate area we get stuck in an uninterruptible infinite loop, much like the ZERO_PAGE issue. While looking at this problem, PeterZ realized you'll get into similar trouble when hitting any install_special_pages() mapping. And are there still drivers setting up their own special mmaps without page->mapping, and without special VM or pte flags to make get_user_pages fail? In most cases, if page->mapping is NULL, we do not need to retry at all: Linus points out that even /proc/sys/vm/drop_caches poses no problem, because it ends up using remove_mapping(), which takes care not to interfere when the page reference count is raised. But there is still one case which does need a retry: if memory pressure called shmem_writepage in between get_user_pages_fast dropping page table lock and our acquiring page lock, then the page gets switched from filecache to swapcache (and ->mapping set to NULL) whatever the refcount. Fault it back in to get the page->mapping needed for key->shared.inode.
