2010-09-23tweak the mclgeti algorithm to behave better under load.David Gwynne
instead of letting hardware rings grow on every interrupt, restrict it so it can only grow once per softclock tick. we can only punish the rings on softclock ticks, so it make sense to only grow on softclock tick boundaries too. the rings are now punished after >1 lost softclock tick rather than >2. mclgeti is now more aggressive at detecting livelock. the rings get punished by an 8th, rather than by half. we now allow the rings to be punished again even if the system is already considered in livelock. without this diff a livelocked system will have its rx ring sizes scale up and down very rapidly, while holding the rings low for too long. this affected throughput significantly. discussed and tested heavily at j2k10. there are still some games with softnet we can play, but this is a good first step. "put it in" and ok deraadt@ ok claudio@ krw@ henning@ mcbride@ if we find out that it sucks we can pull it out again later. till then we'll run with it and see how it goes.

2010-09-23returning here can cause the usb task thread to go to sleep forever,Jacob Meuser
becaue it skips a wakeup() later on. this is the only error condition that returns before the wakeup. not sure why this particular case is handled differently, and not certain what the error code should be, but this is better than breaking all of usb because of a problem on one port. dicussed with deraadt
2010-09-23add two members to struct usb_taskJacob Meuser
* usbd_device_handle dev - the device responsible for the task. use this to not run the task if the device's hub is dying. * int running - a flag to be set when the task is running. add usb_rem_wait_task(), a wrapper for usb_rem_task() that waits for the task to complete if the task is already running. s/usb_rem_task/usb_rem_wait_task/ in usb_detach(). probably most drivers using usb_tasks should do this as well. although device attach/detach is serialized in normal cases, in the special case where the usb bus is hotpluggable (like cardbus/pcmcia), devices are not detached in the task thread.
2010-09-23add a 'dying' flag to struct usbd_bus. use this to signify the busJacob Meuser
is dying, instead of setting a flag in struct usb_softc. as usbd_device_handle has a pointer to the usbd_bus it's attached to, usb devices, and functions they run or functions run on their behalf, can now easily check if their bus is dying. use this to stop usbd_do_request* from running and the usb task thread from adding new tasks when a device's bus is dying.
2010-09-23instead of waiting the full power-up-to-power-steady time for rootJacob Meuser
hubs before their first port explore, check how long it's actually been since power up and only wait as necessary. saves a little time on boot, especially now that explore tasks are serialized. ok yuo@

OK dlg@
2010-09-23instead of running usb_explore() from individual kthreads for eachJacob Meuser
USB bus, make usb_explore() a usb_task. reduces races during normal USB device detach, since now usb_tasks and detach happen in the same process. ok yuo@, matthew@ helped with the task thread loop

2010-09-22Support for AES-GCM-16 and ENCR_NULL_AUTH_AES_GMAC in ESP as perMike Belopuhov
RFC 4106 and 4543. Authentication hash key is set to be the same as an encryption key. The length that is specified for the authentication hash descriptor denotes the the length of Additional Authentication Data (AAD). The encryption transformation descriptor length denotes the length of the payload (to be encrypted and authenticated). ENCR_NULL_AUTH_AES_GMAC treats all input as AAD, thus the encryption length is set to zero. This also fixes padding for stream ciphers, so that payload will be 4-byte aligned.
2010-09-22Add a new interface pppx(4) -- the ppp multiplexer to be used with npppdClaudio Jeker
and pipex. pppx(4) creates an interface whenever a session is created so that altq and pf can work on these. Started by dlg@ debugged and made usable by myself OK dlg@ yasuoka@ deraadt@
2010-09-22Add AES-GCM Transform Identifiers as specified by IANA inMike Belopuhov
RFC 4106 and 4543. Please note that although IKEv1 and IKEv2 identifiers are different for ESP_NULL_AUTH_AES-GMAC (SADB_X_EALG_AESGMAC), we use the IKEv2 one only (which is 21). ipsecctl(8) will be taught to handle exported SA correctly.
2010-09-22Revert previous and let drivers register counterless interrupts;Miod Vallat
tc_intr_disestablish() prototype is changed to carry information whether the counter needs to be detached or not. This does not matter much since no driver ever calls tc_intr_disestablish().
2010-09-22OCF support for the Galois/Counter Mode (GCM) for AES asMike Belopuhov
described in FIPS SP 800-38D. This implementation supports 16 byte authentication tag only, splitting transformation into two parts: encryption and authentication. Encryption is handled by the existing AES-CTR implementation, while authentication requires new AES_GMAC hash function. Additional routine is added to the software crypto driver to deal with peculiarities of a combined authentication- encryption transformation. With suggestions from reyk, naddy and toby.
2010-09-22Switch to unconditionally attaching evcounts on TurboChannelMatthew Dempsky
interrupts, since inspecting the code, they seem to always attach anyway. This fixes compiler fallout from my evcount simplification. build error reported by naddy@; "seems sensible" deraadt@
2010-09-22Call bus_dmamap_sync() of a dma descriptor before checking the ownershipClaudio Jeker
of the descriptor. Diff created and tested by Loganaden Velvindron. Looks good dlg@ and myself
2010-09-22Add DIOCGPDINFO to drivers that were lacking it. Where thereKenneth R Westerback
is no easily available physical information outside of the stored disklabel just make it a synonym for DIOCGDINFO. Commit on the theory it is unlikely to harm, and fallout can be addressed in the mass re-compile that will follow j2k10. Should allow auto-allocation of disks to work with all devices. ok deraadt@

2010-09-22when vscsi is closed request a detach of its children devices fromDavid Gwynne
the same thread theyre attached in (syswq) rather than in teh vscsi process context. this serialises attach and detach so we can avoid weird races with autoconf. also, count the devices on the bus rather than the outstanding commands. fixes some stuff for matthew@ ok matthew@

2010-09-21In i915_gem_idle, don't fail if we have a wedged chipset (this onlyOwain Ainsworth
happens when waiting for the gpu), the reset function will at the very least clean out all of our unwanted buffers, which is all we wanted to do here ourselves. so we can continue with disabling the hardware and cleaning up then return success. Fixes a QUIESCE crash for krw when he had a wedged gpu (``it works, ok krw@''). matthew@ hit a similar thing and this should fix it.
2010-09-21Use RING_WAIT state for the ringbuffer and the instdone debug registerOwain Ainsworth
when we check for gpu hangs. This makes catching some situations a bit more reliable so that large gpu programs don't trigger hangcheck, and also the ring_wait can unhang the chip for us without needin to do a reset. Merge of two patches from Chris Wilson ``upstream''. Running this here for a few days.
2010-09-21Don't dereference null pointers for protocols without port numbers.Stuart Henderson
From henning@, fixed pflog_bgpcopy crashes.
2010-09-21On gen3 hardware always unconditionally set the C3_LP_WRITE_ENABLE bitOwain Ainsworth
in ARB_STATE. Without this bit, C{2,3,4} power states can't complete render writes this has been known to cause painful hangs on some 945s where the bios doesn't set this bit for us. Code from Dave Airlie ``upstream''.
