This is unique being a place where you can get called with BH on, off, or IRQs off. Given that this is only used for printk, the easiest solution is probably just to disable local IRQs instead of BH.

| * [IPVS]: Use msleep_interruptable() instead of ssleep() aka msleep()Simon Horman2006-12-111-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Dean Manners notices that when an IPVS synchonisation daemons are started the system load slowly climbs up to 1. This seems to be related to the call to ssleep(1) (aka msleep(1000) in the main loop. Replacing this with a call to msleep_interruptable() seems to make the problem go away. Though I'm not sure that it is correct. This is the second edition of this patch, which replaces ssleep() in the main loop for both the master and backup threads, as well as some thread synchronisation code. The latter is just for thorougness as it shouldn't be causing any problems. Signed-Off-By: Simon Horman <horms@verge.net.au> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | Spotted by David Miller when compiling on sparc64, I reproduced it here on parisc64, that are the only platforms to define __kernel_suseconds_t as an 'int', all the others, x86_64 and x86 included typedef it as a 'long', but from the definition of suseconds_t it should just be an 'int' on platforms where it is >= 32bits, it would not require all the castings from suseconds_t to (int) when printking variables of this type, that are not needed on parisc64 and sparc64.

| * [DCCP] ccid3: Perform history operations only after packet has been sentGerrit Renker2006-12-111-29/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Renker2006-12-111-20/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Renker2006-12-112-1/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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>

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 Renker2006-12-111-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Renker2006-12-113-35/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Renker2006-12-111-17/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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%.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | [AVR32] Add missing #include <linux/param.h> to delay.cHaavard Skinnemoen2006-12-081-0/+1
| | | | | | | | | | | | | | | | | | __const_udelay() needs HZ, which is defined in <asm/param.h>. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>

| | | | | | | | | | | | | | | | | | | | | Fix build breakage resulting from the extra dev parameter added to dma_cache_sync(). Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
| * | [AVR32] Implement intc_get_pending()Haavard Skinnemoen2006-12-081-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | intc_get_pending() returns a bitmask with pending interrupts in a interrupt controller group (irq). This is used by the upcoming oprofile implementation for avr32 and may also be useful for chained interrupt controller drivers. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
| * | [AVR32] Don't include <asm/delay.h>Haavard Skinnemoen2006-12-082-2/+1
| | | | | | | | | | | | | | | | | | Include <linux/delay.h> instead of <asm/delay.h> from a few places. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
| * | [AVR32] Put the chip in "stop" mode when halting the systemHaavard Skinnemoen2006-12-081-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | Make machine_halt() execute a sleep instruction to put the chip in "stop" mode when the system is halted. This switches off all clocks except the 32 kHz oscillator, which is needed for the RTC to keep ticking. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
| * | [AVR32] Set flow handler for external interruptsHaavard Skinnemoen2006-12-081-2/+20
| | | | | | | | | | | | | | | | | | | | | | | | Make sure that the flow handler for external interrupts is updated whenever they type is changed. Also make sure that the defaults correspond with how the interrupt controller is configured. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>

| * | [AVR32] Remove mii_phy_addr and eth_addr from eth_platform_dataHaavard Skinnemoen2006-12-082-11/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The macb driver will probe for the PHY chip and read the mac address from the MACB registers, so we don't need them in eth_platform_data anymore. Since u-boot doesn't currently initialize the MACB registers with the mac addresses, the tag parsing code is kept but instead of sticking the information into eth_platform_data, it uses it to initialize the MACB registers (in case the boot loader didn't do it.) This code should be unnecessary at some point in the future. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
| * | [AVR32] Move ethernet tag parsing to board-specific codeHaavard Skinnemoen2006-12-082-32/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | By moving the ethernet tag parsing to the board-specific code we avoid the issue of figuring out which device we're supposed to attach the information to. The board specific code knows this because it's where the actual devices are instantiated. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>

| * | | [POWERPC] Generic BUG for powerpcJeremy Fitzhardinge2006-12-118-134/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes powerpc use the generic BUG machinery. The biggest reports the function name, since it is redundant with kallsyms, and not needed in general. There is an overall reduction of code, since module_32/64 duplicated several functions. Unfortunately there's no way to tell gcc that BUG won't return, so the BUG macro includes a goto loop. This will generate a real jmp instruction, which is never used.
