* ofw_pci: Fix incorrectly sized softc causing pci(4) out-of-bounds readsJessica Clarke3 days1-0/+1
| | | | | | | | | | | | | | | | We do not include sys/rman.h and so machine/resource.h ends up not being included by the time pci_private.h is included. This means PCI_RES_BUS is never defined, and so the sc_bus member of pci_softc is not present when compiling ofw_pci, resulting in the wrong softc size being passed to DEFINE_CLASS_1 and thus any attempts by pci(4) to access that member are out-of-bounds reads or writes. This is pretty fragile; arguably pci_private.h should be including sys/rman.h, but this is the minimal needed change to fix the bug whilst maintaining the status quo.

* cxgbe(4): Fix bad races between sysctl and driver detach.Navdeep Parhar3 days4-40/+23
| | | | | | | | | | | | | | | | | | | The default sysctl context setup by newbus for a device is eventually freed by device_sysctl_fini, which runs after the device driver's detach routine. sysctl nodes associated with this context must not use any resources (like driver locks, hardware access, counters, etc.) that are released by driver detach. There are a lot of sysctl nodes like this in cxgbe(4) and the fix is to hang them off a context that is explicitly freed by the driver before it releases any resource that might be used by a sysctl. This fixes panics when running "sysctl dev.t6nex dev.cc" in a tight loop and loading/unloading the driver in parallel.

* mana: Add RX fencingWei Hu4 days2-5/+68
| | | | | | | | | | | | | RX fencing allows the driver to know that any prior change to the RQs has finished, e.g. when the RQs are disabled/enabled or the hashkey/indirection table are changed, RX fencing is required. Remove the previous 'sleep' workaround and add the real support for RX fencing as the PF driver supports the MANA_FENCE_RQ request now (any old PF driver not supporting the request won't be used in production).

* xen: use an hypercall for shutdown and rebootRoger Pau Monné5 days1-12/+6
| | | | | | | | | | | | | | | When running as a Xen guest it's easier to use an hypercall in order to do power management operations (power off, power cycle). Do this for all supported guest types (HVM and PVH). Note that for HVM the power operation could also be done using ACPI, but there's no reason to differentiate between PVH and HVM. While there fix the shutdown handler to properly differentiate between power cycle and power off requests. Reported by: Freddy DISSAUX MFC: 1 week Sponsored by: Citrix Systems R&D

* dwwdt: make it actually usefulAndriy Gapon7 days1-11/+20
| | | | | | | | | | | | | | | | | | | | | | | Flip dwwdt_prevent_restart to false. What's the use of a watchdog if it does not restart a hung system? Add a knob for panic-ing on the first timeout, resetting on the second one. This can be useful if interrupts can still work, otherwise a reset recovers a system without any aid for debugging the hang. The change also doubles the timeout that's programmed into the hardware. The previous version of the code always had the interrupt on the first timeout enabled, but it took no action on it. Only the second timeout could be configured to reset the system. So, the hardware timeout was set to a half of the user requested timeout. But now,we can take a corrective action on the first timeout, so we use the user requested timeout. While here, define boolean sysctl-s as such. Reviewed by: manu MFC after: 3 weeks Differential Revision: https://reviews.freebsd.org/D33534

* hwpmc: Fix amd/arm64/armv7/uncore sampling overflow raceJessica Clarke8 days4-21/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a counter more than overflows just as we read it on switch out then, if using sampling mode, we will negate this small value to give a huge reload count, and if we later switch back in that context we will validate that value against pm_reloadcount and panic an INVARIANTS kernel with: panic: [pmc,1470] pmcval outside of expected range cpu=2 ri=16 pmcval=fffff292 pm_reloadcount=10000 or similar. Presumably in a non-INVARIANTS kernel we will instead just use the provided value as the reload count, which would lead to the overflow not happing for a very long time (e.g. 78 minutes for a 48-bit counter incrementing at an averate rate of 1GHz). Instead, clamp the reload count to 0 (which corresponds precisely to the value we would compute if it had just overflowed and no more), which will result in hwpmc using the full original reload count again. This is the approach used by core for Intel (for both fixed and programmable counters). As part of this, armv7 and arm64 are made conceptually simpler; rather than skipping modifying the overflow count for sampling mode counters so it's always kept as ~0, those special cases are removed so it's always applicable and the concatentation of it and the hardware counter can always be viewed as a 64-bit counter, which also makes them look more like other architectures. Whilst here, fix an instance of UB (shifting a 1 into the sign bit) for amd in its sign-extension code.

* ccr: Use a software OCF session for requests which fallback to software.John Baldwin13 days1-343/+50
| | | | | | | | | | | | | | | | | | | | | | | | | Previously the driver duplicated code from cryptosoft.c to handle certain edge case AES-CCM and AES-GCM requests. However, this approach has a few downsides: 1) It only uses "plain" software and not accelerated software since it uses enc_xform directly. 2) It performs the operation synchronously even though the caller believes it is invoking an async driver. This was fine for the original use case of requests with only AAD and no payload that execute quickly, but is a bit more disingenuous for large requests which fall back due to exceeding the size of a firmware work request (e.g. due to large scatter/gather lists). 3) It has required several updates since ccr(4) was added to the tree. Instead, allocate a software session for AES-CCM and AES-GCM sessions and dispatch a cloned request asynchronusly to the software session.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The introduction of <sched.h> improved compatibility with some 3rd party software, but caused the configure scripts of some ports to assume that they were run in a GLIBC compatible environment. Parts of sched.h were made conditional on -D_WITH_CPU_SET_T being added to ports, but there still were compatibility issues due to invalid assumptions made in autoconfigure scripts. The differences between the FreeBSD version of macros like CPU_AND, CPU_OR, etc. and the GLIBC versions was in the number of arguments: FreeBSD used a 2-address scheme (one source argument is also used as the destination of the operation), while GLIBC uses a 3-adderess scheme (2 source operands and a separately passed destination). The GLIBC scheme provides a super-set of the functionality of the FreeBSD macros, since it does not prevent passing the same variable as source and destination arguments. In code that wanted to preserve both source arguments, the FreeBSD macros required a temporary copy of one of the source arguments. This patch set allows to unconditionally provide functions and macros expected by 3rd party software written for GLIBC based systems, but breaks builds of externally maintained sources that use any of the following macros: CPU_AND, CPU_ANDNOT, CPU_OR, CPU_XOR. One contributed driver (contrib/ofed/libmlx5) has been patched to support both the old and the new CPU_OR signatures. If this commit is merged to -STABLE, the version test will have to be extended to cover more ranges. Ports that have added -D_WITH_CPU_SET_T to build on -CURRENT do no longer require that option. The FreeBSD version has been bumped to 1400046 to reflect this incompatible change. Reviewed by: kib MFC after: 2 weeks Relnotes: yes Differential Revision: https://reviews.freebsd.org/D33451
