A kref_put is done for each class_device registered. When the + * class_device is released, the coresponding kref_put is done in the release + * method. Every time one of the device's channels is allocated to a client, + * a kref_get occurs. When the channel is freed, the coresponding kref_put + * happens. The device's release function does a completion, so + * unregister_device does a remove event, class_device_unregister, a kref_put + * for the first reference, then waits on the completion for all other + * references to finish. + * + * Each channel has an open-coded implementation of Rusty Russell's "bigref," + * with a kref and a per_cpu local_t. A single reference is set when on an + * ADDED event, and removed with a REMOVE event. Net DMA client takes an + * extra reference per outstanding transaction.

Available from: + * ftp://ftp.cs.arizona.edu/xkernel/Papers/jsac.ps + * + * See http://www.cs.arizona.edu/xkernel/ for their implementation. + * The main aspects that distinguish this implementation from the + * Arizona Vegas implementation are: + * o We do not change the loss detection or recovery mechanisms of + * Linux in any way. Linux already recovers from losses quite well, + * using fine-grained timers, NewReno, and FACK. + * o To avoid the performance penalty imposed by increasing cwnd + * only every-other RTT during slow start, we increase during + * every RTT during slow start, just like Reno. + * o Largely to allow continuous cwnd growth during slow start, + * we use the rate at which ACKs come back as the "actual" + * rate, rather than the rate at which data is sent. + * o To speed convergence to the right rate, we set the cwnd + * to achieve the right ("actual") rate when we exit slow start. + * o To filter out the noise caused by delayed ACKs, we use the + * minimum RTT sample observed during the last RTT to calculate + * the actual rate. + * o When the sender re-starts from idle, it waits until it has + * received ACKs for an entire flight of new data before making + * a cwnd adjustment decision. The original Vegas implementation + * assumed senders never went idle. + * + * + * TCP Compound based on TCP Vegas + * + * further details can be found here: + * ftp://ftp.research.microsoft.com/pub/tr/TR-2005-86.pdf + */ + +#include <linux/config.h> +#include <linux/mm.h> +#include <linux/module.h> +#include <linux/skbuff.h> +#include <linux/inet_diag.h> + +#include <net/tcp.h> + +/* Default values of the Vegas variables, in fixed-point representation + * with V_PARAM_SHIFT bits to the right of the binary point. + */ +#define V_PARAM_SHIFT 1 + +#define TCP_COMPOUND_ALPHA 3U +#define TCP_COMPOUND_BETA 1U +#define TCP_COMPOUND_GAMMA 30 +#define TCP_COMPOUND_ZETA 1 + +/* TCP compound variables */ +struct compound { + u32 beg_snd_nxt; /* right edge during last RTT */ + u32 beg_snd_una; /* left edge during last RTT */ + u32 beg_snd_cwnd; /* saves the size of the cwnd */ + u8 doing_vegas_now; /* if true, do vegas for this RTT */ + u16 cntRTT; /* # of RTTs measured within last RTT */ + u32 minRTT; /* min of RTTs measured within last RTT (in usec) */ + u32 baseRTT; /* the min of all Vegas RTT measurements seen (in usec) */ + + u32 cwnd; + u32 dwnd; +}; + +/* There are several situations when we must "re-start" Vegas: + * + * o when a connection is established + * o after an RTO + * o after fast recovery + * o when we send a packet and there is no outstanding + * unacknowledged data (restarting an idle connection) + * + * In these circumstances we cannot do a Vegas calculation at the + * end of the first RTT, because any calculation we do is using + * stale info -- both the saved cwnd and congestion feedback are + * stale. + * + * Instead we must wait until the completion of an RTT during + * which we actually receive ACKs. + */ +static inline void vegas_enable(struct sock *sk) +{ + const struct tcp_sock *tp = tcp_sk(sk); + struct compound *vegas = inet_csk_ca(sk); + + /* Begin taking Vegas samples next time we send something. */ + vegas->doing_vegas_now = 1; + + /* Set the beginning of the next send window. */ + vegas->beg_snd_nxt = tp->snd_nxt; + + vegas->cntRTT = 0; + vegas->minRTT = 0x7fffffff; +} + +/* Stop taking Vegas samples for now. */ +static inline void vegas_disable(struct sock *sk) +{ + struct compound *vegas = inet_csk_ca(sk); + + vegas->doing_vegas_now = 0; +} + +static void tcp_compound_init(struct sock *sk) +{ + struct compound *vegas = inet_csk_ca(sk); + const struct tcp_sock *tp = tcp_sk(sk); + + vegas->baseRTT = 0x7fffffff; + vegas_enable(sk); + + vegas->dwnd = 0; + vegas->cwnd = tp->snd_cwnd; +} + +/* Do RTT sampling needed for Vegas. + * Basically we: + * o min-filter RTT samples from within an RTT to get the current + * propagation delay + queuing delay (we are min-filtering to try to + * avoid the effects of delayed ACKs) + * o min-filter RTT samples from a much longer window (forever for now) + * to find the propagation delay (baseRTT) + */ +static void tcp_compound_rtt_calc(struct sock *sk, u32 usrtt) +{ + struct compound *vegas = inet_csk_ca(sk); + u32 vrtt = usrtt + 1; /* Never allow zero rtt or baseRTT */ + + /* Filter to find propagation delay: */ + if (vrtt < vegas->baseRTT) + vegas->baseRTT = vrtt; + + /* Find the min RTT during the last RTT to find + * the current prop. delay + queuing delay: + */ + + vegas->minRTT = min(vegas->minRTT, vrtt); + vegas->cntRTT++; +} + +static void tcp_compound_state(struct sock *sk, u8 ca_state) +{ + + if (ca_state == TCP_CA_Open) + vegas_enable(sk); + else + vegas_disable(sk); +} + + +/* 64bit divisor, dividend and result. dynamic precision */ +static inline u64 div64_64(u64 dividend, u64 divisor) +{ + u32 d = divisor; + + if (divisor > 0xffffffffULL) { + unsigned int shift = fls(divisor >> 32); + + d = divisor >> shift; + dividend >>= shift; + } + + /* avoid 64 bit division if possible */ + if (dividend >> 32) + do_div(dividend, d); + else + dividend = (u32) dividend / d; + + return dividend; +} + +/* calculate the quartic root of "a" using Newton-Raphson */ +static u32 qroot(u64 a) +{ + u32 x, x1; + + /* Initial estimate is based on: + * qrt(x) = exp(log(x) / 4) + */ + x = 1u << (fls64(a) >> 2); + + /* + * Iteration based on: + * 3 + * x = ( 3 * x + a / x ) / 4 + * k+1 k k + */ + do { + u64 x3 = x; + + x1 = x; + x3 *= x; + x3 *= x; + + x = (3 * x + (u32) div64_64(a, x3)) / 4; + } while (abs(x1 - x) > 1); + + return x; +} + + +/* + * If the connection is idle and we are restarting, + * then we don't want to do any Vegas calculations + * until we get fresh RTT samples.
