* Include ktr.h in more compilation unitsConrad Meyer2019-05-213-1/+3
| | | | | | | | | | | | | | | | | | Similar to r348026, exhaustive search for uses of CTRn() and cross reference ktr.h includes. Where it was obvious that an OS compat header of some kind included ktr.h indirectly, .c files were left alone. Some of these files clearly got ktr.h via header pollution in some scenarios, or tinderbox would not be passing prior to this revision, but go ahead and explicitly include it in files using it anyway. Like r348026, these CUs did not show up in tinderbox as missing the include.

* Include eventhandler.h in more compilation unitsConrad Meyer2019-05-213-0/+3
| | | | | | | | | | | | | | | | This was enumerated with exhaustive search for sys/eventhandler.h includes, cross-referenced against EVENTHANDLER_* usage with the comm(1) utility. Manual checking was performed to avoid redundant includes in some drivers where a common os_bsd.h (for example) included sys/eventhandler.h indirectly, but it is possible some of these are redundant with driver-specific headers in ways I didn't notice. (These CUs did not show up as missing eventhandler.h in tinderbox.) X-MFC-With: r347984 Notes: svn path=/head/; revision=348026

* Extract eventfilter declarations to sys/_eventfilter.hConrad Meyer2019-05-202-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | This allows replacing "sys/eventfilter.h" includes with "sys/_eventfilter.h" in other header files (e.g., sys/{bus,conf,cpu}.h) and reduces header pollution substantially. EVENTHANDLER_DECLARE and EVENTHANDLER_LIST_DECLAREs were moved out of .c files into appropriate headers (e.g., sys/proc.h, powernv/opal.h). As a side effect of reduced header pollution, many .c files and headers no longer contain needed definitions. The remainder of the patch addresses adding appropriate includes to fix those files. LOCK_DEBUG and LOCK_FILE_LINE_ARG are moved to sys/_lock.h, as required by sys/mutex.h since r326106 (but silently protected by header pollution prior to this change). No functional change (intended). Of course, any out of tree modules that relied on header pollution for sys/eventhandler.h, sys/lock.h, or sys/mutex.h inclusion need to be fixed. __FreeBSD_version has been bumped.

* tun/tap: merge and rename to `tuntap`Kyle Evans2019-05-082-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | tun(4) and tap(4) share the same general management interface and have a lot in common. Bugs exist in tap(4) that have been fixed in tun(4), and vice-versa. Let's reduce the maintenance requirements by merging them together and using flags to differentiate between the three interface types (tun, tap, vmnet). This fixes a couple of tap(4)/vmnet(4) issues right out of the gate: - tap devices may no longer be destroyed while they're open [0] - VIMAGE issues already addressed in tun by kp [0] emaste had removed an easy-panic-button in r240938 due to devdrn blocking. A naive glance over this leads me to believe that this isn't quite complete -- destroy_devl will only block while executing d_* functions, but doesn't block the device from being destroyed while a process has it open. The latter is the intent of the condvar in tun, so this is "fixed" (for certain definitions of the word -- it wasn't really broken in tap, it just wasn't quite ideal). ifconfig(8) also grew the ability to map an interface name to a kld, so that `ifconfig {tun,tap}0` can continue to autoload the correct module, and `ifconfig vmnet0 create` will now autoload the correct module. This is a low overhead addition. (MFC commentary) This may get MFC'd if many bugs in tun(4)/tap(4) are discovered after this, and how critical they are. Changes after this are likely easily MFC'd without taking this merge, but the merge will be easier. I have no plans to do this MFC as of now.

* random(4): Restore availability tradeoff prior to r346250Conrad Meyer2019-04-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As discussed in that commit message, it is a dangerous default. But the safe default causes enough pain on a variety of platforms that for now, restore the prior default. Some of this is self-induced pain we should/could do better about; for example, programmatic CI systems and VM managers should introduce entropy from the host for individual VM instances. This is considered a future work item. On modern x86 and Power9 systems, this may be wholly unnecessary after D19928 lands (even in the non-ideal case where early /boot/entropy is unavailable), because they have fast hardware random sources available early in boot. But D19928 is not yet landed and we have a host of architectures which do not provide fast random sources. This change adds several tunables and diagnostic sysctls, documented thoroughly in UPDATING and sys/dev/random/random_infra.c.

| | | | | | | | | | | | | | | | | | | | | | | | | | Embedded lzma decompression library becomes a module usable by other consumers, in addition to geom_uzip. Most important code changes are - removal of XZ_DEC_SINGLE define, we need the code to work with XZ_DEC_DYNALLOC; - xz_crc32_init() call is removed from geom_uzip, xz module handles initialization on its own. xz is no longer embedded into geom_uzip, instead the depend line for the module is provided, and corresponding kernel option is added to each MIPS kernel config file using geom_uzip. The commit also carries unrelated cleanup by removing excess "device geom_uzip" in places which were missed in r344479.

* Performance improvements for octe(4):Nathan Whitehorn2019-02-103-19/+14
| | | | | | | | | | | | | | | | | | - Distribute RX load across multiple cores, if present. This reverts r217212, which is no longer relevant (I think because of the newer SDK). - Use newer APIs for pinning taskqueue entries to specific cores. - Deepen RX buffers. This more than doubles NAT forwarding throughput on my EdgeRouter Lite from, with typical packet mixture, 90 Mbps to over 200 Mbps. The result matches forwarding throughput in Linux without the UBNT hardware offload on the same hardware, and thus likely reflects hardware limits.
