| | | | | | | | | | | | | | | GETATTRs being generated - one from lookup()/namei() and the other from nfs_open() (for cto consistency). This change eliminates the GETATTR in nfs_open() if an otw GETATTR was done from the namei() path. Instead of extending the vop interface, we timestamp each attr load, and use this to detect whether a GETATTR was done from namei() for this syscall. Introduces a thread-local variable that counts the syscalls made by the thread and uses <pid, tid, thread syscalls> as the attrload timestamp. Thanks to jhb@ and peter@ for a discussion on thread state that could be used as the timestamp with minimal overhead. Notes: svn path=/head/; revision=167352

| | | | | | | | | | | | | | | | | | | * To use this option with a UDP socket, it must be bound to a local port, and INADDR_ANY, to disallow possible collisions with existing udp inpcbs bound to the same port on other interfaces at send time. * If the socket is bound to INADDR_ANY, specifying IP_SENDSRCADDR with INADDR_ANY will be rejected as it is ambiguous. * If the socket is bound to an address other than INADDR_ANY, specifying IP_SENDSRCADDR with INADDR_ANY will be disallowed by in_pcbbind_setup().

| | | | | | | | | | | | | | | | | | | | | in the field. In one situation, one end of the TCP connection sends a back-to-back RST packet, with delayed ack, the last_ack_sent variable has not been update yet. When tcp_insecure_rst is turned off, the code treats the RST as invalid because last_ack_sent instead of rcv_nxt is compared against th_seq. Apparently there is some kind of firewall that sits in between the two ends and that RST packet is the only RST packet received. With short lived HTTP connections, the symptom is a large accumulation of connections over a short period of time . The +/-(1) factor is to take care of implementations out there that generate RST packets with these types of sequence numbers. This behavior has also been observed in live environments.

Together with the previous change this also allows to fully take advantage of newbus in that drivers like fhc(4), which attach on multiple parent busses, no longer require different bus front-ends as obtaining the OFW node and properties as well as resource allocation works the same for all supported busses. As such this change also is part 4/4 of allowing creator(4) to work in USIII-based machines as it allows this driver to attach on both nexus(4) and upa(4). On the other hand removing these IVARs breaks API compatibility with the powerpc nexus(4) but which isn't that bad as a) sparc64 currently doesn't share any device driver hanging off of nexus(4) with powerpc and b) they were no longer compatible regarding OFW-related extensions at the pci(4) level since quite some time. o Provide bus_get_dma_tag methods in nexus(4) and its children in order to handle DMA tags in a hierarchical way and get rid of the sparc64_root_dma_tag kludge. Together with the previous two items this changes also allows to completely get rid of the nexus(4) IVAR interface. It also includes: - pushing the constraints previously specified by the nexus_dmatag down into the DMA tags of psycho(4) and sbus(4) as it's their IOMMUs which induce these restrictions (and nothing at the nexus(4) or anything that would warrant specifying them there), - fixing some obviously wrong constraints of the psycho(4) and sbus(4) DMA tags, which happened to not actually be used with the sparc64_root_dma_tag kludge in place and therefore didn't cause problems so far, - replacing magic constants for constraints with macros as far as it is obvious as to where they come from. This doesn't include taking advantage of the newbus way to get the parent DMA tags implemented by this change in order to divorce the IOTSBs of the PCI and SBus IOMMUs or for implementing the workaround for the DMA sync bug in Sabre (and Tomatillo) bridges, yet, though. o Get rid of the notion that nexus(4) (mostly) reflects an UPA bus by replacing ofw_upa.h and with ofw_nexus.h (which was repo-copied from ofw_upa.h) and renaming its content, which actually applies to all of Fireplane/Safari, JBus and UPA (in the host bus case), as appropriate. o Just use M_DEVBUF instead of a separate M_NEXUS malloc type for allocating the device info for the children of nexus(4). This is done in order to not need to export M_NEXUS when deriving drivers for subordinate busses from the nexus(4) class. o Use the DEFINE_CLASS_0() macro to declare the nexus(4) driver so we can derive subclasses from it. o Const'ify the nexus_excl_name and nexus_excl_type arrays as well as add 'associations' and 'rsc', which are pseudo-devices without resources and therefore of no real interest for nexus(4), to the former. o Let the nexus(4) device memory rman manage the entire 64-bit address space instead of just the UPA_MEMSTART to UPA_MEMEND subregion as Fireplane/Safari- and JBus-based machines use multiple ranges, which can't be as easily divided as in the case of UPA (limiting the address space only served for sanity checking anyway). o Use M_WAITOK instead of M_NOWAIT when allocating the device info for children of nexus(4) in order to give one less opportunity for adding devices to nexus(4) to fail. o While adapting the drivers affected by the above nexus(4) changes, change them to take advantage of rman_get_rid() instead of caching the RIDs assigned to allocated resources, now that the RIDs of resources are correctly set. o In iommu(4) and nexus(4) replace hard-coded functions names, which actually became outdated in several places, in panic strings and status massages with __func__. [1] o Use driver_filter_t in prototypes where appropriate. o Add my copyright to creator(4), fhc(4), nexus(4), psycho(4) and sbus(4) as I changed considerable amounts of these drivers as well as added a bunch of new features, workarounds for silicon bugs etc. o Fix some white space nits. Due to lack of access to Exx00 hardware, these changes, i.e. central(4) and fhc(4), couldn't be runtime tested on such a machine. Exx00 are currently reported to panic before trying to attach nexus(4) anyway though. PR: 76052 [1] Approved by: re (kensmith) Notes: svn path=/head/; revision=167308

| | | | | | | | | | | | | | | | | | never correct as CAM has no real understanding of it, and will just immediately retry the command. This leads to undesirable cycling of the camisr as well as a high possibility for the command to exhaust its retries before the driver can get around to servicing it. The better fix, as demonstrated here, is to freeze the simq and mark the command as needing to be tried. Then when driver can service the command, the simq gets unfrozen. This is correct, and documented here to help reduce the mystery. However, it also points out a shortcoming in CAM error handling that makes writing drivers harder.
