xennet(4): Membar audit.
- xennet_tx_complete: Other side owns rsp_prod, giving us responses
to tx commands. We own rsp_cons, recording which responess we've
processed already.
1. Other side initializes responses before advancing rsp_prod, so
we must observe rsp_prod before trying to examine the responses.
Hence load from rsp_prod must be followed by xen_rmb.
(Can this just use atomic_load_acquire?)
2. As soon as other side observes rsp_event, it may start to
overwrite now-unused response slots, so we must finish using the
response before advancing rsp_cons. Hence we must issue xen_wmb
before store to rsp_event.
(Can this just use atomic_store_release?)
(Should this use RING_FINAL_CHECK_FOR_RESPONSES?)
3. When loop is done and we set rsp_event, we must ensure the other
side has had a chance to see that we want more before we check
whether there is more to consume; otherwise the other side might
not bother to send us an interrupt. Hence after setting
rsp_event, we must issue xen_mb (store-before-load) before
re-checking rsp_prod.
- xennet_handler (rx): Same deal, except the xen_mb is buried in
RING_FINAL_CHECK_FOR_RESPONSES. Unclear why xennet_tx_complete has
this open-coded while xennet_handler (rx) uses the macro.
XXX pullup-8 (at least the xen_mb part; requires patch)
XXX pullup-9 (at least the xen_mb part; requires patch)

Welcome XENPVHVM mode. It is UP only, has xbd(4) and xennet(4) as PV drivers. The console is com0 at isa and the native portion is very rudimentary AT architecture, so is probably suboptimal to run without PV support.

Bifurcate the interrupt establish functions between XEN and non-XEN Thus intr_establish_xname() becomes xen_intr_establish_xname() etc. One consequence of this is that dom0 devices expect the native function calls to be available and we thus provide weak aliasing for dom0 builds to succeed. XEN and non-XEN devices are distinguished by the PIC they are established on. XEN interrupts are exclusively established on xen_pic, while dom0 interrupts are established on natively available PICs. This allows us an orthogonal path to xen device management (eg: xenstore events) in XENPVHVM, without having to worry about unifying the vector entry paths, etc., which is quite challenging.

Rename min/max -> uimin/uimax for better honesty. These functions are defined on unsigned int. The generic name min/max should not silently truncate to 32 bits on 64-bit systems. This is purely a name change -- no functional change intended. HOWEVER! Some subsystems have #define min(a, b) ((a) < (b) ? (a) : (b)) #define max(a, b) ((a) > (b) ? (a) : (b)) even though our standard name for that is MIN/MAX. Although these may invite multiple evaluation bugs, these do _not_ cause integer truncation. To avoid `fixing' these cases, I first changed the name in libkern, and then compile-tested every file where min/max occurred in order to confirm that it failed -- and thus confirm that nothing shadowed min/max -- before changing it. I have left a handful of bootloaders that are too annoying to compile-test, and some dead code: cobalt ews4800mips hp300 hppa ia64 luna68k vax acorn32/if_ie.c (not included in any kernels) macppc/if_gm.c (superseded by gem(4)) It should be easy to fix the fallout once identified -- this way of doing things fails safe, and the goal here, after all, is to _avoid_ silent integer truncations, not introduce them. Maybe one day we can reintroduce min/max as type-generic things that never silently truncate. But we should avoid doing that for a while, so that existing code has a chance to be detected by the compiler for conversion to uimin/uimax without changing the semantics until we can properly audit it all. (Who knows, maybe in some cases integer truncation is actually intended!)

Implement the BPF direction filter (BIOC[GS]DIRECTION). It provides backward compatibility with BIOC[GS]SEESENT ioctl. The userland interface is the same as FreeBSD.

Restore MP-safety annotations in intr_establish_xname. In the old API, event_set_handler would assume MP-unsafe for IPL_VM and MP-safe for all other levels (IPL_SCHED, IPL_HIGH). The recent Xen interrupt rototill started passing known_mpsafe=true for _all_ interrupt handlers. Change it to known_mpsafe=false for the IPL_VM (= IPL_CLOCK, IPL_NET) ones.

Move bpf_mtap and if_ipackets++ on Rx of each driver to percpuq if_input
The benefits of the change are:
- We can reduce codes
- We can provide the same behavior between drivers
- Where/When if_ipackets is counted up
- Note that some drivers still update packet statistics in their own
way (periodical update)
- Moved bpf_mtap run in softint
- This makes it easy to MP-ify bpf

Introduce softint-based if_input This change intends to run the whole network stack in softint context (or normal LWP), not hardware interrupt context. Note that the work is still incomplete by this change; to that end, we also have to softint-ify if_link_state_change (and bpf) which can still run in hardware interrupt. This change softint-ifies at ifp->if_input that is called from each device driver (and ieee80211_input) to ensure Layer 2 runs in softint (e.g., ether_input and bridge_input). To this end, we provide a framework (called percpuq) that utlizes softint(9) and percpu ifqueues. With this patch, rxintr of most drivers just queues received packets and schedules a softint, and the softint dequeues packets and does rest packet processing. To minimize changes to each driver, percpuq is allocated in struct ifnet for now and that is initialized by default (in if_attach). We probably have to move percpuq to softc of each driver, but it's future work. At this point, only wm(4) has percpuq in its softc as a reference implementation. Additional information including performance numbers can be found in the thread at tech-kern@ and tech-net@: http://mail-index.netbsd.org/tech-kern/2016/01/14/msg019997.html Acknowledgment: riastradh@ greatly helped this work.

Be a little more clear and consistent about harvesting entropy from devices: 1) deprecate RND_FLAG_NO_ESTIMATE 2) define RND_FLAG_COLLECT_TIME, RND_FLAG_COLLECT_VALUE 3) define RND_FLAG_ESTIMATE_TIME, RND_FLAG_ESTIMATE_VALUE 4) define RND_FLAG_DEFAULT: RND_FLAG_COLLECT_TIME| RND_FLAG_COLLECT_VALUE|RND_FLAG_ESTIMATE_TIME 5) Make entropy harvesting from environmental sensors a little more generic and remove it from individual sensor drivers. 6) Remove individual open-coded delta-estimators for values from a few places in the tree (uvm, environmental drivers). 7) 0 -> RND_FLAG_DEFAULT, actually gather entropy from various drivers that had stubbed out code, other minor cleanups.

Extend the xpmap API, as described in [1]. This change is mechanical and avoids exposing the MD phys_to_machine/machine_to_phys tables directly. Added: - xpmap_ptom handles PFN (pseudo physical) to MFN (machine frame number) translations, and is under control of the domain. - xpmap_mtop is its counterpart (MFN to PFN), and is under control of hypervisor. xpmap_ptom_map() map a pseudo-phys address to a machine address xpmap_ptom_unmap() unmap a pseudo-phys address (invalidation) xpmap_ptom_isvalid() check for pseudo-phys address validity The parameters are physical/machine addresses, like bus_dma/bus_space(9). As x86 MFNs are tracked by u_long (Xen's choice) while machine addresses can be 64 bits entities (PAE), use ptoa() to avoid truncation when bit shifting by PAGE_SHIFT. I kept the same namespace (xpmap_) to avoid code churn. [1] http://mail-index.netbsd.org/port-xen/2009/05/09/msg004951.html XXX will document ptoa/atop/trunc_page separately.

Entropy-pool implementation move and cleanup. 1) Move core entropy-pool code and source/sink/sample management code to sys/kern from sys/dev. 2) Remove use of NRND as test for presence of entropy-pool code throughout source tree. 3) Remove use of RND_ENABLED in device drivers as microoptimization to avoid expensive operations on disabled entropy sources; make the rnd_add calls do this directly so all callers benefit. 4) Fix bug in recent rnd_add_data()/rnd_add_uint32() changes that might have lead to slight entropy overestimation for some sources. 5) Add new source types for environmental sensors, power sensors, VM system events, and skew between clocks, with a sample implementation for each. ok releng to go in before the branch due to the difficulty of later pullup (widespread #ifdef removal and moved files). Tested with release builds on amd64 and evbarm and live testing on amd64.

First step of random number subsystem rework described in <20111022023242.BA26F14A158@mail.netbsd.org>. This change includes the following: An initial cleanup and minor reorganization of the entropy pool code in sys/dev/rnd.c and sys/dev/rndpool.c. Several bugs are fixed. Some effort is made to accumulate entropy more quickly at boot time. A generic interface, "rndsink", is added, for stream generators to request that they be re-keyed with good quality entropy from the pool as soon as it is available. The arc4random()/arc4randbytes() implementation in libkern is adjusted to use the rndsink interface for rekeying, which helps address the problem of low-quality keys at boot time. An implementation of the FIPS 140-2 statistical tests for random number generator quality is provided (libkern/rngtest.c). This is based on Greg Rose's implementation from Qualcomm. A new random stream generator, nist_ctr_drbg, is provided. It is based on an implementation of the NIST SP800-90 CTR_DRBG by Henric Jungheim. This generator users AES in a modified counter mode to generate a backtracking-resistant random stream. An abstraction layer, "cprng", is provided for in-kernel consumers of randomness. The arc4random/arc4randbytes API is deprecated for in-kernel use. It is replaced by "cprng_strong". The current cprng_fast implementation wraps the existing arc4random implementation. The current cprng_strong implementation wraps the new CTR_DRBG implementation. Both interfaces are rekeyed from the entropy pool automatically at intervals justifiable from best current cryptographic practice. In some quick tests, cprng_fast() is about the same speed as the old arc4randbytes(), and cprng_strong() is about 20% faster than rnd_extract_data(). Performance is expected to improve. The AES code in src/crypto/rijndael is no longer an optional kernel component, as it is required by cprng_strong, which is not an optional kernel component. The entropy pool output is subjected to the rngtest tests at startup time; if it fails, the system will reboot. There is approximately a 3/10000 chance of a false positive from these tests. Entropy pool _input_ from hardware random numbers is subjected to the rngtest tests at attach time, as well as the FIPS continuous-output test, to detect bad or stuck hardware RNGs; if any are detected, they are detached, but the system continues to run. A problem with rndctl(8) is fixed -- datastructures with pointers in arrays are no longer passed to userspace (this was not a security problem, but rather a major issue for compat32). A new kernel will require a new rndctl. The sysctl kern.arandom() and kern.urandom() nodes are hooked up to the new generators, but the /dev/*random pseudodevices are not, yet. Manual pages for the new kernel interfaces are forthcoming.

Fix a fallout with my xensuspend merge: talk_to_backend() returns a boolean, so checking for "true" with "== 0" is... wrong. Now xennet(4) should work as expected, and not stay in the InitWait state (which blocks network communication with the backend). Thanks to riz@ and sborrill@ for reporting breakage with -current xennet(4) after my merge.

Merge jym-xensuspend branch in -current. ok bouyer@. Goal: save/restore support in NetBSD domUs, for i386, i386 PAE and amd64. Executive summary: - split all Xen drivers (xenbus(4), grant tables, xbd(4), xennet(4)) in two parts: suspend and resume, and hook them to pmf(9). - modify pmap so that Xen hypervisor does not cry out loud in case it finds "unexpected" recursive memory mappings - provide a sysctl(7), machdep.xen.suspend, to command suspend from userland via powerd(8). Note: a suspend can only be handled correctly when dom0 requested it, so provide a mechanism that will prevent kernel to blindly validate user's commands The code is still in experimental state, use at your own risk: restore can corrupt backend communications rings; this can completely thrash dom0 as it will loop at a high interrupt level trying to honor all domU requests. XXX PAE suspend does not work in amd64 currently, due to (yet again!) page validation issues with hypervisor. Will fix. XXX secondary CPUs are not suspended, I will write the handlers in sync with cherry's Xen MP work. Tested under i386 and amd64, bear in mind ring corruption though. No build break expected, GENERICs and XEN* kernels should be fine. ./build.sh distribution still running. In any case: sorry if it does break for you, contact me directly for reports.

Under rare occasions, the xenbus watcher can fire multiple times, overwriting the I/O ring memory mappings with invalid values. This will lead sooner or later to dom0 panic(). Will ask for pullup. FWIW, xbdback(4) is not affected. Check status before proceeding further. Avoids spurious watch calls.

Pull up following revision(s) (requested by jym in ticket #1608):
sys/arch/xen/xen/if_xennet_xenbus.c: revision 1.49
Separate xennet(4) backend initialization code ("resume") from the part
that talks with Xenstore to query backend's information. Resuming is now
performed just after xennet(4) attachment instead of waiting for backend
to announce its features in Xenstore and change it state.
This fixes the race observed by Urban Boquist when the domU boots with
root on NFS.
FWIW, the boot code (when root is NFS-backed) can innit() the xennet(4)
interface very early: it tried to access ifnet structures that were not
yet allocated.
Will ask for a pullup. Thanks to Urban for reporting the issue and
investigate it. Confirmed fixed. No regression observed by me for
dynamic attach/detach of xvif(4) and xennet(4) interfaces.

Redefine bpf linkage through an always present op vector, i.e. #if NBPFILTER is no longer required in the client. This change doesn't yet add support for loading bpf as a module, since drivers can register before bpf is attached. However, callers of bpf can now be modularized. Dynamically loadable bpf could probably be done fairly easily with coordination from the stub driver and the real driver by registering attachments in the stub before the real driver is loaded and doing a handoff. ... and I'm not going to ponder the depths of unload here. Tested with i386/MONOLITHIC, modified MONOLITHIC without bpf and rump.

- Upgrade suspend/resume code to comply with Xen2 removal. - Add support for PAE domUs suspend/resume. - Fix an issue regarding initialization of the xbd ring I/O that could end badly during resume, with invalid block operations submitted to dom0 backend. NetBSD supports PAE under x86_32 by considering the L2 page as being 4 pages long instead of 1. Xen validates the page types during resume. Sadly, the hypervisor handles alternative recursive mappings (== PG/PD entries pointing to pages other than self) inadequately, which could lead to incorrect page pinning. As a result, the important change with this patch is to clear these alternative mappings during suspend, and reset them back to their former self upon resume. For PAE, approx. all 4 PDIR_SLOT_PTEs could be considered as alternative recursive mappings. See comments in pmap.c for further details. Now, let the testing and bug hunting begin.

Modifications for the Xen suspend/migrate/resume branch:
- introduce xenbus_device_{suspend,resume}() functions. These are routines
used to suspend/resume MI parts of the Xenbus device interfaces, like updating
frontend/backend devices' paths found in XenStore.
- introduce HYPERVISOR_sysctl(), an hypercall used only by Xentools to obtain
information from hypervisor (listing VMs, printing console, etc.). I use it
to query xenconsole from ddb(), as a last resort in case of a panic() in
dom0 (xm being not available). Currently unused in the branch; could be, if
requested.
- disable the rwlock(9) used to protect code that could use transient MFNs.
It could trigger nasty context switches in place it should not to.
- fix some bugs in the xennet/xbd suspend/resume pmf(9) handlers.
- following XenSource's design, talk_to_otherend() is now called
watch_otherend(), and free_otherend_details() is used by Xenbus device
suspend/resume routines.
- some slight modifications in pmap regarding APDP. Introduce an inline
function (pmap_unmap_apdp_pde()) that clears APDP entry for the current pmap.
- similarly, implement pmap_unmap_all_apdp_pdes() that iterates through all
pmaps and tears down APDP, as Xen does not handle them properly.
TODO/XXX:
- pmap_unmap_apdp_pde() does not handle APDP shadow entry of PAE. It will,
once I figure out how PAE uses it.
- revisit the pmap locking issue regarding transient MFNs. As NetBSD does not
use kernel preemption and MP for Xen, this could be skipped momentarily. See
http://mail-index.netbsd.org/port-xen/2009/04/27/msg004903.html for details.
- fix a bug regarding grant tables which could technically DoS a dom0 if
ridiculously high consumer/producer indexes are passed down in the ring during
a resume.
All in all, once the grant table index issue and APDP PAE are fixed, next step
is to torture test this branch.
Tested under i386 PAE and non-PAE, Xen3 dom0 and domU. amd64 is only compile
tested.

Patch from Brian Marcotte on port-xen@: write a "feature-rx-notify" to the xenstore, which is used by recent linux dom0 kernels. This reduce packet loss when using a NetBSD domU on such linux dom0. This entry is ignored by NetBSD and older linux domUs.

Initial code for xen save/restore/migrate facilities.
- split the attach code of frontends in two half: one that is only needed
during autoconf(9) attach/detach phases, and one used at each save/restore
of device state (between suspend and resume).
Applies to hypervisor, xencons, xenbus, xbd, and xennet.
- add a rwlock(9) ("ptom_lock") to protect the different parts in the kernel
that manipulate MFNs (which could change between a suspend and a resume,
without the kernel noticing it). Parts that require MFNs acquire a reader lock,
while suspend code will acquire a writer lock to ensure that no-other parts
in kernel still use MFNs.
- integrate the suspend code with sysmon.
- various things in pmap(9), and clock.
TODO:
- factorize code a bit more inside frontends drivers.
- remove all alternative recursive (APDP_PDE) mappings found in PD/PT during
suspend, as Xen does not support them.
- abstract the ptom_lock locking, it is only required when kernel preemption
is enabled, or on MP systems.
Current code works mostly. You may experience difficulties in some corner
cases (dom0 warnings about xennet interface errors, and Xen tools failing to
validate NetBSD's alternative pmaps).

Merge the bouyer-xeni386 branch. This brings in PAE support to NetBSD xeni386
(domU only). PAE support is enabled by 'options PAE', see the new XEN3PAE_DOMU
and INSTALL_XEN3PAE_DOMU kernel config files.
See the comments in arch/i386/include/{pte.h,pmap.h} to see how it works.
In short, we still handle it as a 2-level MMU, with the second level page
directory being 4 pages in size. pmap switching is done by switching the
L2 pages in the L3 entries, instead of loading %cr3. This is almost required
by Xen, which handle the last L2 page (the one mapping 0xc0000000 - 0xffffffff)
in a very special way. But this approach should also work for native PAE
support if ever supported (in fact, the pmap should almost suport native
PAE, what's missing is bootstrap code in locore.S).

Merge the ppcoea-renovation branch to HEAD. This branch was a major cleanup and rototill of many of the various OEA cpu based PPC ports that focused on sharing as much code as possible between the various ports to eliminate near-identical copies of files in every tree. Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here.

Add a bootstatic callback for dom0, which allows to take NFS boot informations from the command line (nfsroot=, ip=) in the same way domUs did. While there convert a for (;;) loop to TAILQ_FOREACH(). From Christoph Egger in private mail. Make all bootstatic callbacks return the new NFS_BOOTSTATIC_NOSTATIC flag when no nfs boot information is found on command line.

Apply patch (requested by bouyer in ticket #1245): Pull up Xen3 domU support. This adds support for the Xen-3 memory bootstrap, xenstore, and block and network device frontend. Xen-3 support is turned on by 'options XEN3', which disable Xen-2 support. Changes affecting non-xen3 specific code: - xbd and xennet at hypervisor now attaches with xbd_hypervisor and xennet_hypervisor - x86_atomic_* renamed to xen_atomic_* - use genassim.cf to pull in more constant from include files for assembly - Map the shared info page from locore.S instead of the 0xffffffff hack in xen_machdep.c - remove some unused code - some __asm__ __volatile__ -> __asm volatile and __inline__ -> inline - more debug code
