2015-06-09NFC: Introduce vendor commands structuresSamuel Ortiz3-0/+36
Together with inline routines to associate a vendor commands array with an NFC device. Vendor commands allow vendors to implement their very specific operations from driver code instead of adding new stack ops for non NFC generic commands. Vendors need to select their own unique IDs and use that as a namespace for defining sub commands. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

2015-06-08NFC: trf7970a: Handle extra byte in response to Type 5 RMB commandsMark A. Greer2-4/+23
The current versions of the trf7970a has an erratum where it returns an extra byte in the response to 'Read Multiple Block' (RMB) commands. This command is issued to Type 5 tags (i.e., ISO/IEC 15693 tags) by the neard daemon. To handle this, define a new Device Tree property, 't5t-rmb-extra-byte-quirk', which indicates that the associated trf7970a device has this erratum. The trf7970a device driver will then ensure that the response length to RMB commands is reduced by one byte (for devices with the erratum). Signed-off-by: Mark A.

Jaeden Amero says: ==================== net/phy: micrel: Center FLP timing at 16ms In v2, we add an additional cleanup commit to make an array of strings static const and to improve const correctness generally. We also no longer unnecessarily initialize the result variable in ksz9031_center_flp_timing(). In v3, we remove the unnecessary result variable from ksz9031_config_init() introduced by a previous version of "net/phy: micrel: Center FLP timing at 16ms". In v4, we modify the commit message of "net/phy: micrel: Center FLP timing at 16ms" to replace the awkward quotation of the data sheet's programming procedure with an explanation of why we program the FLP burst registers and restart auto-negotiation where we do (config_init). ==================== Signed-off-by: David S.

2015-06-08net/phy: micrel: Center FLP timing at 16msJaeden Amero1-1/+22
Link failures have been observed when using the KSZ9031 with HP 1810-8G and HP 1910-8G network switches. Center the FLP timing at 16ms to help avoid intermittent link failures. >From the KSZ9031RNX and KSZ9031MNX data sheets revision 2.2, section "Auto-Negotiation Timing": The KSZ9031[RNX or MNX] Fast Link Pulse (FLP) burst-to-burst transmit timing for Auto-Negotiation defaults to 8ms. IEEE 802.3 Standard specifies this timing to be 16ms +/-8ms. Some PHY link partners need to receive the FLP with 16ms centered timing; otherwise, there can be intermittent link failures and long link-up times. The PHY data sheet recommends configuring the FLP burst registers after power-up/reset and immediately thereafter restarting auto-negotiation, so we center the FLP timing at 16ms and then restart auto-negotiation in the config_init for KSZ9031.

2015-06-07fib_trie: coding style: Use pointer after checkFiro Yang1-8/+13
As Alexander Duyck pointed out that: struct tnode { ... struct key_vector kv[1]; } The kv[1] member of struct tnode is an arry that refernced by a null pointer will not crash the system, like this: struct tnode *p = NULL; struct key_vector *kv = p->kv; As such p->kv doesn't actually dereference anything, it is simply a means for getting the offset to the array from the pointer p.

In little endian cases, __constant_cpu_to_le16 and cpu_to_le16 expand directly to the same expression.

2015-06-07net: fec: ptp: correct the ENET_ATCOR valueFugang Duan1-0/+1
The current driver adjust freq formula is: fe * diff = ppb * pc Note: fe: ENET ref clock frequency in Hz diff = inc_corr - inc: difference between default increment and correction increment ppb: parts per billion adjustment from base pc: correction period (in number of fe clock cycles) The correction increment will be used after N cycles of regular increments, not every N cycles (with N being the correction period). For example, set ENET_ATCOR=4, INC=8, INC_CORR=9, there will be 4 increments of 8 (ENET_ATINC[INC]) , followed by 1 increment of 9 (ENET_ATINC[INC_CORR]). So, the correct formula is: fe * diff = ppb * (pc + 1) For ENET_ATCOR, a value 0 disables the correction counter and no corrections occur. So base on the origin formula, set pc = pc > 1 ? pc - 1 : pc. Signed-off-by: Fugang Duan <B38611@freescale.com> Signed-off-by: Frank Li <Frank.Li@freescale.com> Signed-off-by: David S.

2015-06-07bpf: make programs see skb->data == L2 for ingress and egressAlexei Starovoitov4-29/+30
eBPF programs attached to ingress and egress qdiscs see inconsistent skb->data. For ingress L2 header is already pulled, whereas for egress it's present. This is known to program writers which are currently forced to use BPF_LL_OFF workaround. Since programs don't change skb internal pointers it is safe to do pull/push right around invocation of the program and earlier taps and later pt->func() will not be affected. Multiple taps via packet_rcv(), tpacket_rcv() are doing the same trick around run_filter/BPF_PROG_RUN even if skb_shared. This fix finally allows programs to use optimized LD_ABS/IND instructions without BPF_LL_OFF for higher performance. tc ingress + cls_bpf + samples/bpf/tcbpf1_kern.o w/o JIT w/JIT before 20.5 23.6 Mpps after 21.8 26.6 Mpps Old programs with BPF_LL_OFF will still work as-is.

2015-06-06inet: add IP_BIND_ADDRESS_NO_PORT to overcome bind(0) limitationsEric Dumazet5-2/+13
When an application needs to force a source IP on an active TCP socket it has to use bind(IP, port=x). As most applications do not want to deal with already used ports, x is often set to 0, meaning the kernel is in charge to find an available port. But kernel does not know yet if this socket is going to be a listener or be connected. It has very limited choices (no full knowledge of final 4-tuple for a connect()) With limited ephemeral port range (about 32K ports), it is very easy to fill the space. This patch adds a new SOL_IP socket option, asking kernel to ignore the 0 port provided by application in bind(IP, port=0) and only remember the given IP address. The port will be automatically chosen at connect() time, in a way that allows sharing a source port as long as the 4-tuples are unique. This new feature is available for both IPv4 and IPv6 (Thanks Neal) Tested: Wrote a test program and checked its behavior on IPv4 and IPv6. strace(1) shows sequences of bind(IP=127.0.0.2, port=0) followed by connect(). Also getsockname() show that the port is still 0 right after bind() but properly allocated after connect(). socket(PF_INET, SOCK_STREAM, IPPROTO_IP) = 5 setsockopt(5, SOL_IP, IP_BIND_ADDRESS_NO_PORT, [1], 4) = 0 bind(5, {sa_family=AF_INET, sin_port=htons(0), sin_addr=inet_addr("127.0.0.2")}, 16) = 0 getsockname(5, {sa_family=AF_INET, sin_port=htons(0), sin_addr=inet_addr("127.0.0.2")}, [16]) = 0 connect(5, {sa_family=AF_INET, sin_port=htons(53174), sin_addr=inet_addr("127.0.0.3")}, 16) = 0 getsockname(5, {sa_family=AF_INET, sin_port=htons(38050), sin_addr=inet_addr("127.0.0.2")}, [16]) = 0 IPv6 test : socket(PF_INET6, SOCK_STREAM, IPPROTO_IP) = 7 setsockopt(7, SOL_IP, IP_BIND_ADDRESS_NO_PORT, [1], 4) = 0 bind(7, {sa_family=AF_INET6, sin6_port=htons(0), inet_pton(AF_INET6, "::1", &sin6_addr), sin6_flowinfo=0, sin6_scope_id=0}, 28) = 0 getsockname(7, {sa_family=AF_INET6, sin6_port=htons(0), inet_pton(AF_INET6, "::1", &sin6_addr), sin6_flowinfo=0, sin6_scope_id=0}, [28]) = 0 connect(7, {sa_family=AF_INET6, sin6_port=htons(57300), inet_pton(AF_INET6, "::1", &sin6_addr), sin6_flowinfo=0, sin6_scope_id=0}, 28) = 0 getsockname(7, {sa_family=AF_INET6, sin6_port=htons(60964), inet_pton(AF_INET6, "::1", &sin6_addr), sin6_flowinfo=0, sin6_scope_id=0}, [28]) = 0 I was able to bind()/connect() a million concurrent IPv4 sockets, instead of ~32000 before patch. lpaa23:~# ulimit -n 1000010 lpaa23:~# ./bind --connect --num-flows=1000000 & 1000000 sockets lpaa23:~# grep TCP /proc/net/sockstat TCP: inuse 2000063 orphan 0 tw 47 alloc 2000157 mem 66 Check that a given source port is indeed used by many different connections : lpaa23:~# ss -t src :40000 | head -10 State Recv-Q Send-Q Local Address:Port Peer Address:Port ESTAB 0 0 127.0.0.2:40000 127.0.202.33:44983 ESTAB 0 0 127.0.0.2:40000 127.2.27.240:44983 ESTAB 0 0 127.0.0.2:40000 127.2.98.5:44983 ESTAB 0 0 127.0.0.2:40000 127.0.124.196:44983 ESTAB 0 0 127.0.0.2:40000 127.2.139.38:44983 ESTAB 0 0 127.0.0.2:40000 127.1.59.80:44983 ESTAB 0 0 127.0.0.2:40000 127.3.6.228:44983 ESTAB 0 0 127.0.0.2:40000 127.0.38.53:44983 ESTAB 0 0 127.0.0.2:40000 127.1.197.10:44983 Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

2015-06-05Merge branch 'cxgb4-next'David S. Miller5-51/+257
Hariprasad Shenai says: ==================== Free VI, flush sge ec and some other misc. fixes This patch series adds the following. Free VI interface during remove, flush SGE ec routine, rename t4_link_start to t4_link_l1cfg since it only does l1 configuration, set mac addr from when we can't contact firmware for debug purpose, set pcie completion timeout and use fw interface to access TP_PIO_XXX registers This patch series has been created against net-next tree and includes patches on cxgb4 driver. We have included all the maintainers of respective drivers. Kindly review the change and let us know in case of any review comments. ==================== Signed-off-by: David S.

2015-06-05cxgb4: Use FW LDST cmd to access TP_PIO_{ADDR, DATA} register firstHariprasad Shenai2-21/+83
The TP_PIO_{ADDR,DATA} registers are are in conflict with the firmware's use of these registers. Added a routine to access it through FW LDST cmd. Access all TP_PIO_{ADDR,DATA} register access through new routine if FW is alive. If firmware is dead, than fall back to indirect access.
