2014-02-17HID: remove hidinput_input_event handlerBenjamin Tissoires1-4/+0

2014-02-17netfilter: nf_tables: fix nf_trace always-on with XT_TRACE=nFlorian Westphal1-1/+4
When using nftables with CONFIG_NETFILTER_XT_TARGET_TRACE=n, we get lots of "TRACE: filter:output:policy:1 IN=..." warnings as several places will leave skb->nf_trace uninitialised. Unlike iptables tracing functionality is not conditional in nftables, so always copy/zero nf_trace setting when nftables is enabled. Move this into __nf_copy() helper.

2014-02-17netdevice: move netdev_cap_txqueue for shared usage to headerDaniel Borkmann1-0/+20

2014-02-17netdevice: add queue selection fallback handler for ndo_select_queueDaniel Borkmann1-3/+6
Add a new argument for ndo_select_queue() callback that passes a fallback handler. This gets invoked through netdev_pick_tx(); fallback handler is currently __netdev_pick_tx() as most drivers invoke this function within their customized implementation in case for skbs that don't need any special handling. This fallback handler can then be replaced on other call-sites with different queue selection methods (e.g. in packet sockets, pktgen etc). This also has the nice side-effect that __netdev_pick_tx() is then only invoked from netdev_pick_tx() and export of that function to modules can be undone. Suggested-by: David S.

SPMI states that a slave may contain two register spaces, the Base register space is a 5-bit byte-addressable space accessed via the Register Read/Write and Register Zero Write command sequences, and the Extended register space: a 16-bit byte-addressable space accessed via the Extended Read/Write and Extended Read/Write Long command sequences.

2014-02-15tty: Fix ref counting for port krefsPeter Hurley1-3/+3
The tty core supports two models for handling tty_port lifetimes; the tty_port can use the kref supplied by tty_port (which will automatically destruct the tty_port when the ref count drops to zero) or it can destruct the tty_port manually. For tty drivers that choose to use the port kref to manage the tty_port lifetime, it is not possible to safely acquire a port reference conditionally. If the last reference is released after evaluating the condition but before acquiring the reference, a bogus reference will be held while the tty_port destruction commences. Rather, only acquire a port reference if the ref count is non-zero and allow the caller to distinguish if a reference has successfully been acquired.

Marcelo Ricardo Leitner reported problems when the forwarding link path has a lower mtu than the incoming one if the inbound interface supports GRO. Given: Host <mtu1500> R1 <mtu1200> R2 Host sends tcp stream which is routed via R1 and R2. R1 performs GRO. In this case, the kernel will fail to send ICMP fragmentation needed messages (or pkt too big for ipv6), as GSO packets currently bypass dstmtu checks in forward path. Instead, Linux tries to send out packets exceeding the mtu. When locking route MTU on Host (i.e., no ipv4 DF bit set), R1 does not fragment the packets when forwarding, and again tries to send out packets exceeding R1-R2 link mtu. This alters the forwarding dstmtu checks to take the individual gso segment lengths into account. For ipv6, we send out pkt too big error for gso if the individual segments are too big. For ipv4, we either send icmp fragmentation needed, or, if the DF bit is not set, perform software segmentation and let the output path create fragments when the packet is leaving the machine. It is not 100% correct as the error message will contain the headers of the GRO skb instead of the original/segmented one, but it seems to work fine in my (limited) tests. Eric Dumazet suggested to simply shrink mss via ->gso_size to avoid sofware segmentation. However it turns out that skb_segment() assumes skb nr_frags is related to mss size so we would BUG there. I don't want to mess with it considering Herbert and Eric disagree on what the correct behavior should be. Hannes Frederic Sowa notes that when we would shrink gso_size skb_segment would then also need to deal with the case where SKB_MAX_FRAGS would be exceeded. This uses sofware segmentation in the forward path when we hit ipv4 non-DF packets and the outgoing link mtu is too small. Its not perfect, but given the lack of bug reports wrt. GRO fwd being broken this is a rare case anyway. Also its not like this could not be improved later once the dust settles.

2014-02-13PCI/MSI: Add pci_enable_msi_exact() and pci_enable_msix_exact()Alexander Gordeev1-0/+20
The new functions are special cases for pci_enable_msi_range() and pci_enable_msix_range() when a particular number of MSI or MSI-X is needed. By contrast with pci_enable_msi_range() and pci_enable_msix_range() functions, pci_enable_msi_exact() and pci_enable_msix_exact() return zero in case of success, which indicates MSI or MSI-X interrupts have been successfully allocated.

2014-02-13serial: max310x: Always use dynamic GPIO ID assignmentAlexander Shiyan1-3/+0
Always register GPIOs and use dynamic GPIO ID assignment. This is no much worth if GPIOs is not used, but helps remove private driver header and add DT support in the future. Additionally, patch adds missing uart_unregister_driver() call if probe() fails. Signed-off-by: Alexander Shiyan <shc_work@mail.ru> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
