2016-03-17KNF: Remove a blank line.Masao Uebayashi
2016-03-17Only attempt to build the pci sdhc attachment when it is configured.Jonathan Gray
Don't require it when building other sdhc attachments. From Patrick Wildt.
2016-03-17- add realloc_pages to move a buffer's physmem from one range to another.Bob Beck
- modify B_DMA handling to be in vfs_biomem.c - change buffer allocation to try allocations with NOWAIT and to throw away clean pages if allocation fails - allocate with WAITOK only if you can't throw away enough pages to succeed "probably sound" deraadt@
2016-03-16Make urndis(4) print tx/rx errors only if compiled in DEBUG mode.Stefan Sperling
These printfs were causing too much noise in dmesg during regular operation. And don't forget to count input errors. ok sthen@ mpi@
2016-03-16Remove redundant check.Stefan Kempf
The compiler is also smart enough to recognize that this is redundant. The resulting code on amd64 is basically equivalent (slightly different register allocation and instruction scheduling). ok mpi@ deraadt@

2016-03-15Allocate amap slots for a virtual memory range reserved with sbrk lazily.Stefan Kempf
This avoids wasting kernel memory if the user process does not make use of the allocated memory. Testing by sthen@ and tobiasu@, thanks! ok deraadt@
2016-03-15For amaps with only a few slots, allocate the slots via pool(9)Stefan Kempf
This saves some memory compared to using malloc, because there's no roundup to the next bucket size. And it reduces kmem pressure at least for some architectures (e.g. amd64). Testing by sthen@ and tobiasu@, thanks! ok sthen@ deraadt@

it factorizes path resolution in resolvpath() function, and use it in sys_pledge() and pledge_namei(). please note that wl_paths is still disabled.
2016-03-13Introduce memory ranges to support VMs with >= 4G RAMStefan Kempf
Kernel bits: - When creating a VM, a list of memory ranges has to be specified, similar to the BIOS memory map. This is necessary for VMs with RAM sizes approaching 4G because we'll need PCI MMIO space in the higher parts of the 32 bit address space. vmctl and vmd bits: - Construct appropriate memory ranges to create a VM with a given RAM size - Construct a corresponding BIOS memory map from the memory ranges and update the boot params page accordingly. - Make sure that all variables that represent guest physical addresses match the address width of the target CPU instead of using uint32_t. - Fix some integer promotion glitches that actually restricted VM RAM size to 2G. This changes the VM create ioctl interface, so update your kernel, vmd, and vmctl. ok mlarkin@
2016-03-13In ichiic(4), ignore the SMBALERT# interrupt. This interrupt has beenStefan Sperling
observed to fire for spurious reasons with buggy hardware/bios. It is being ignored by both FreeBSD and Linux as well. Fixes GENERIC kernel boot on ADI RCC-VE with buggy bios versions, where ichiic(4) ended up stealing interrupts from ehci(4), rendering the internal eMMC flash unusable. Also, always ackknowledge all interrupts by writing status bits back to avoid a potential SMBALERT# interrupt storm. with and ok deraadt@ kettenis@ mpi@

2016-03-12Standardize on calling local scsi_link variables 'link' instead ofKenneth R Westerback
'sc_link'. 'sc_link' is a field in the various device *_softc structures, where the sc_ prefix was for 'softc'. Reduces potential mental confusion. Newer code from down under was already using 'link'. No functional change. Prompted by bluhm@'s adventures in scsi. ok dlg@ jmatthew@

2016-03-12When unplugging an USB umass stick, the kernel could panic becauseAlexander Bluhm
of a use after free. In sdopen() the scsi link pointer is taken from the scsi disk struct. While the scsi disk memory is refcounted by autoconf, the scsi link may be detached and freed during sleep. The solution is to check wether the disk is dying after every sleep. The SDF_DYING flag is set before scsi bus and scsi disk are detached, so without this flag the link must be valid. input and OK krw@
2016-03-12When vfs_busy() is sleeping, it uses RW_SLEEPFAIL and will fail.Alexander Bluhm
So if vop_generic_revoke() does not unmount because the mount point is busy, this could result in a mount point without a valid device. It is better to check and sleep in a loop to avoid a corrupt mount point. OK natano@ krw@

2016-03-11"if (_3btol(cmd->len) != 0)" is more likely to be a useful test thanKenneth R Westerback
"if (cmd->len) != 0)", as cmd->len is a 3 byte array. Broken since media_blkno accounting was introduced in r1.72 (2007!). Might fix some obscure tape issues around miscounting variable sized blocks. Spotted by mmcc@ and his friend clang.
