* [DCCP] ccid3: Perform history operations only after packet has been sentGerrit Renker2006-12-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This migrates all packet history operations into the routine ccid3_hc_tx_packet_sent, thereby removing synchronization problems that occur when, as before, the operations are spread over multiple routines. The following minor simplifications are also applied: * several simplifications now follow from this change - several tests are now no longer required * removal of one unnecessary variable (dp) Justification: Currently packet history operations span two different routines, one of which is likely to pass through several iterations of sleeping and awakening. The first routine, ccid3_hc_tx_send_packet, allocates an entry and sets a few fields. The remaining fields are filled in when the second routine (which is not within a sleeping context), ccid3_hc_tx_packet_sent, is called. This has several strong drawbacks: * it is not necessary to split history operations - all fields can be filled in by the second routine * the first routine is called multiple times, until a packet can be sent, and sleeps meanwhile - this causes a lot of difficulties with regard to keeping the list consistent * since both routines do not have a producer-consumer like synchronization, it is very difficult to maintain data across calls to these routines * the fact that the routines are called in different contexts (sleeping, not sleeping) adds further problems Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk> Acked-by: Ian McDonald <ian.mcdonald@jandi.co.nz> Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com>

* [DCCP] ccid3: Shift window counter computationGerrit Renker2006-12-11
| | | | | | | | | | | | | | | | | | | | | | | This puts the window counter computation [RFC 4342, 8.1] into a separate function which is called whenever a new packet is ready for immediate transmission in ccid3_hc_tx_send_packet. Justification: The window counter update was previously computed after the packet was sent. This has two drawbacks, both fixed by this patch: 1) re-compute another timestamp almost directly after the packet was sent (expensive), 2) the CCVal for the window counter is needed at the instant the packet is sent. Further details: The initialisation of the window counter is left in the state NO_SENT, as before. The algorithm will do nothing if either RTT is initialised to 0 (which is ok) or if the RTT value remains below 4 microseconds (which is almost pathological).

* [DCCP] ccid3: Sanity-check RTT samplesGerrit Renker2006-12-11
| | | | | | | | | | | | | | | | | | | CCID3 performance depends much on the accuracy of RTT samples. If RTT samples grow too large, performance can be catastrophically poor. To limit the amount of possible damage in such cases, the patch * introduces an upper limit which identifies a maximum `sane' RTT value; * uses a macro to enforce this upper limit. Using a macro was given preference, since it is necessary to identify the calling function in the warning message. Since exceeding this threshold identifies a critical condition, DCCP_CRIT is used and not DCCP_WARN. Many thanks to Ian McDonald for collaboration on this issue.

* [DCCP] ccid3: Initialise RTT valuesGerrit Renker2006-12-11
| | | | | | | | | | | | | | | | | | In both the sender and the receiver it is possible that the stored RTT value is accessed before an actual RTT estimate has been computed. This patch * initialises the sender RTT to 0 - the sender always accesses the RTT in ccid3_hc_tx_packet_sent - the RTT is further needed for the window counter algorithm * replaces the receiver initialisation of 5msec with 0 - which has the same effect and removes an `XXX' - the RTT value is needed in ccid3_hc_rx_packet_recv as rtt_prev Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk> Acked-by: Ian McDonald <ian.mcdonald@jandi.co.nz> Signed-off-by: Arnaldo Carvalho de Melo <acme@mandriva.com>
* [DCCP] ccid: Deprecate ccid_hc_tx_insert_optionsGerrit Renker2006-12-11
| | | | | | | | | | | | | | | | | The function ccid3_hc_tx_insert_options only does a redundant no-op, as the operation DCCP_SKB_CB(skb)->dccpd_ccval = hctx->ccid3hctx_last_win_count; is already performed _unconditionally_ in ccid3_hc_tx_send_packet. Since there is further no current need for this function, it is removed entirely. Since furthermore, there is actually no present need for the entire interface function ccid_hc_tx_insert_options, it was decided to remove it also, to clean up the interface.

* [DCCP]: Warn when discarding packet due to internal errorsGerrit Renker2006-12-11
| | | | | | | | | | | | | This adds a (debug) warning message which is triggered whenever a packet is discarded due to send failure. It also adds a conditional, so that an interruption during dccp_wait_for_ccid is not treated as a `BUG': the rationale is that interruptions are external, whereas bug warnings are concerned with the internals.

* [DCCP]: Only deliver to the CCID rx side in chargeGerrit Renker2006-12-11
| | | | | | | | | | | | | | | | | | | | | | | This is an optimisation to reduce CPU load. The received feedback is now only directed to the active CCID component, without requiring processing also by the inactive one. As a consequence, a similar test in ccid3.c is now redundant and is also removed. Justification: Currently DCCP works as a unidirectional service, i.e. a listening server is not at the same time a connecting client. As far as I can see, several modifications are necessary until that becomes possible. At the present time, received feedback is both fed to the rx/tx CCID modules. In unidirectional service, only one of these is active at any one time.

* [DCCP]: Simplify TFRC calculationGerrit Renker2006-12-11
| | | | | | | | | | | | | | | | | | | | | In migrating towards using the newer functions scaled_div/scaled_div32 for TFRC computations mapped from floating-point onto integer arithmetic, this completes the last stage of modifications. In particular, the overflow case for computing X_calc is circumvented by * breaking the computation into two stages * the first stage, res = (s*1E6)/R, cannot overflow due to use of u64 * in the second stage, res = (res*1E6)/f, overflow on u32 is avoided due to (i) returning UINT_MAX in this case (which is logically appropriate) and (ii) issuing a warning message into the system log (since very likely there is a problem somewhere else with the parameters) Lastly, all such scaling operations are now exported into tfrc.h, since actually this form of scaled computation is specific to TFRC and not to CCID3.

* [DCCP]: Debug timeval operationsGerrit Renker2006-12-11
| | | | | | | | | | | | | | | | | | | | Problem: Most target types in the CCID3 code are u32, so subtle conversion errors can occur if signed time calculations yield negative results: the original values are lost in the conversion to unsigned, calculation errors go undetected. This patch therefore * sets all critical time types from unsigned to suseconds_t * avoids comparison between signed/unsigned via type-casting * provides ample warning messages in case time calculations are negative These warning messages can be removed at a later stage when the code has undergone more testing.

* [DCCP] ccid3: Simplify calculation for reverse lookup of pGerrit Renker2006-12-11
| | | | | | | | | | | | | | | | | | | | | | | This simplifies the calculation of a value p for a given fval when the first loss interval is computed (RFC 3448, 6.3.1). It makes use of the two new functions scaled_div/scaled_div32 to provide overflow protection. Additionally, protection against divide-by-zero is extended - in this case the function will return the maximally possible value of p=100%. Background: The maximum fval, f(100%), is approximately 244, i.e. the scaled value of fval should never exceed 244E6, which fits easily into u32. The problem is the scaling by 10^6, since additionally R(TT) is in microseconds. This is resolved by breaking the division into two stages: the first stage computes fval=(s*10^6)/R, stores that into u64; the second stage computes fval = (fval*10^6)/X_recv and complains if overflow is reached for u32. This case is safe since the TFRC reverse-lookup routine then returns p=100%.

* [DCCP] ccid3: Finer-grained resolution of sending ratesGerrit Renker2006-12-11
| | | | | | | | | | | | | | | | | | | | | | | This patch * resolves a bug where packets smaller than 32/64 bytes resulted in sending rates of 0 * supports all sending rates from 1/64 bytes/second up to 4Gbyte/second * simplifies the present overflow problems in calculations Current sending rate X and the cached value X_recv of the receiver-estimated sending rate are both scaled by 64 (2^6) in order to * cope with low sending rates (minimally 1 byte/second) * allow upgrading to use a packets-per-second implementation of CCID 3 * avoid calculation errors due to integer arithmetic cut-off The patch implements a revised strategy from http://www.mail-archive.com/dccp@vger.kernel.org/msg01040.html The only difference with regard to that strategy is that t_ipi is already used in the calculation of the nofeedback timeout, which saves one division.

* [DCCP] ccid3: Fix two bugs in sending rate computationGerrit Renker2006-12-11
| | | | | | | | | | | | | | This fixes 1) a bug in the recomputation of the sending rate by the nofeedback timer when no feedback at all has so far been sent by the receiver: min_t was used instead of max_t, which is wrong (cf. RFC 3448, p. 10); 2) an error in the computation of larger initial windows: instead of min(... max()) (cf. RFC 4342, 5.), the code had used max(... max()).

* [DCCP] ccid3: Two optimisations for sending rate recomputationGerrit Renker2006-12-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This performs two optimisations for the recomputation of the sending rate. 1) Currently the target sending rate X_calc is recalculated whenever a) the nofeedback timer expires, or b) a feedback packet is received. In the (a) case, recomputing X_calc is redundant, since * the parameters p and RTT do not change in between the reception of feedback packets; * the parameter X_recv is either modified from received feedback or via the nofeedback timer; * a test (`p == 0') in the nofeedback timer avoids using a stale/undefined value of X_calc if p was previously 0. 2) The nofeedback timer now only recomputes a timestamp when p == 0. This is according to step (4) of [RFC 3448, 4.3] and avoids unnecessarily determining a timestamp. A debug statement about not updating X is also removed - it helps very little in debugging and just clutters the logs.

| | | | | | | | | | | | This patch follows a suggestion by Ian McDonald and ensures that in the current code the value of p can not exceed 100%.

* [NETPOLL]: make arp replies through netpoll use mac address of senderNeil Horman2006-12-08
| | | | | | | | | | | | | | | | | | Back in 2.4 arp requests that were recevied by netpoll were processed in netconsole_receive_skb, where they were responded to using the src mac of the request sender. In the 2.6 kernel arp_reply is responsible for this function, but instead of using the src mac address of the incomming request, the stored mac address that was registered for the netconsole application is used. While this is usually ok, it can lead to failures in netpoll in some situations (specifically situations where a network may have two gateways, as arp requests from one may be responded to using the mac address of the other). This patch reverts the behavior to what we had in 2.4, in which all arp requests are sent back using the src address of the request sender.

Future patches will define BOTHER, ISHIFT and enable newer termios structures for each architecture, and once they are all done some of the ifdefs also vanish.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As per Ralf Baechle's observations, the schedule_work() call should give enough of a memory barrier, so the explicit one here is totally unnecessary. Signed-off-by: David S. Miller <davem@davemloft.net>
| | * | | [NET]: Memory barrier cleanupsRalf Baechle2006-12-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I believe all the below memory barriers only matter on SMP so therefore the smp_* variant of the barrier should be used. I'm wondering if the barrier in net/ipv4/inet_timewait_sock.c should be dropped entirely. schedule_work's implementation currently implies a memory barrier and I think sane semantics of schedule_work() should imply a memory barrier, as needed so the caller shouldn't have to worry. It's not quite obvious why the barrier in net/packet/af_packet.c is needed; maybe it should be implied through flush_dcache_page?

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When user builds IPv6 header and send it through raw socket, kernel tries to release unlocked sock. (Kernel log shows "BUG: bad unlock balance detected" with enabled debug option.) The lock is held only for non-hdrincl sock in this function then this patch fix to do nothing about lock for hdrincl one.
