* Add proto_connect_wait() to wait for connection to finish.pjd2011-02-025-11/+84
| | | | | | | | | | | | | If timeout argument to proto_connect() is -1, then the caller needs to use this new function to wait for connection. This change is in preparation for capsicum, where sandboxed worker wants to ask main process to connect in worker's behalf and pass descriptor to the worker. Because we don't want the main process to wait for the connection, it will start async connection and pass descriptor to the worker who will be responsible for waiting for the connection to finish.

* 1) Allow a chunk to track the cwnd it was at when sent.rrs2011-02-0214-29/+120
| | | | | | | | | | | | | | | | | | | 2) Add separate max-bursts for retransmit and hb. These are set to sysctlable values but not settable via the socket api. This makes sure we don't blast out HB's or fast-retransmits. 3) Determine on the first data transmission on a net if its local-lan (by being under or over a RTT). This can later be used to think about different algorithms based on locallan vs big-i (experimental) 4) The cwnd should NOT be allowed to grow when an ECNEcho is seen (TCP has this same bug). We fix this in SCTP so an ECNe being seen prevents an advance of cwnd. 5) CWR's should not be sent multiple times to the same network, instead just updating the TSN being transmitted if needed.

* For ZFS, change the type of clock_t to int64_t.mm2011-02-011-0/+4
| | | | | | | | | | | | | | The clock_t type in OpenSolaris is long (int64_t on amd64). On FreeBSD clock_t is int32_t. The clock_t type is used in several places in the ZFS code to store system uptime in milliseconds ("seconds * hz"). With hz=1000 we have a 32-bit integer overflow in 24 days, 20 hours, 31 minutes and 23.648 seconds. This has a user reported negative impact on l2arc_feed_thread() and may cause unexpected results from other functions using clock_t.

* The unp_gc() function drops and reaquires lock between scan andkib2011-02-011-12/+16
| | | | | | | | | | | | | | | | | | | | | | collect phases. The unp_discard() function executes unp_externalize_fp(), which might make the socket eligible for gc-ing, and then, later, taskqueue will close the socket. Since unp_gc() dropped the list lock to do the malloc, close might happen after the mark step but before the collection step, causing collection to not find the socket and miss one array element. I believe that the race was there before r216158, but the stated revision made the window much wider by postponing the close to taskqueue sometimes. Only process as much array elements as we find the sockets during second phase of gc [1]. Take linkage lock and recheck the eligibility of the socket for gc, as well as call fhold() under the linkage lock.

| | | | | | | | | | | | | | | | | | | | | | | top 8 bits of the 32 bit signal bit field space for internal use. These private signals should not be leaked outside of a module. Given that many algorithm modules use the NewReno hook functions to simplify their implementation, the obvious place such a leak would show up is in the NewReno cong_signal hook function. - Show the full number of significant bits in the signal type definitions in <netinet/cc.h>. - Add a bitmask to simplify figuring out if a given signal is in the private or public bit range. - Add a sanity check in newreno_cong_signal() to ensure private signals are not being leaked into the hook function.

* Include some preliminary TX HT rate scenario setup code.adrian2011-02-014-1/+246
| | | | | | | | | | | | | | | | The AR5416 and later TX descriptors have new fields for supporting 11n bits (eg 20/40mhz mode, short/long GI) and enabling/disabling RTS/CTS protection per rate. These functions will be responsible for initialising the TX descriptors for the AR5416 and later chips for both HT and legacy frames. Beacon frames will remain using the non-11n TX descriptor setup for now; Linux ath9k does much the same. Note that these functions aren't yet used anywhere; a few more framework changes are needed before all of the right rate information is available for TX.

* Import an implementation of the CAIA-Hamilton-Delay (CHD) congestion controllstewart2011-02-013-1/+508
| | | | | | | | | | | | | | | | | | | | | | algorithm described in the paper "Improved coexistence and loss tolerance for delay based TCP congestion control" by Hayes and Armitage. It is implemented as a kernel module compatible with the recently committed modular congestion control framework. CHD enhances the approach taken by the Hamilton-Delay (HD) algorithm to provide tolerance to non-congestion related packet loss and improvements to coexistence with loss-based congestion control algorithms. A key idea in improving coexistence with loss-based congestion control algorithms is the use of a shadow window, which attempts to track how NewReno's congestion window (cwnd) would evolve. At the next packet loss congestion event, CHD uses the shadow window to correct cwnd in a way that reduces the amount of unfairness CHD experiences when competing with loss-based algorithms.
