1110d0029a Make root_mount_hold() work after boot. This is important for two
reasons. First is rerooting into USB-mounted device that happens
to be not yet enumerated. The second is when mounting with (non-root)
filesystem on USB device on a hub that's enumerated later than the root
mount: the rc scripts explicitly mount for the root mount holds to be
released, but each USB bus takes the hold asynchronously, and if that
happens after root mount, it would just get ignored.

4f9d7bad48 In r290196 the root mount hold mechanism was changed to make it not wait
for mount hold release if the root device already exists.  So, unless your
rootdev is not on USB - ie in the usual case - the root mount won't wait
for USB.  However, the old behaviour was sometimes used as "wait until USB
is fully enumerated", and r290196 broke that.

This commit adds vfs.root_mount_always_wait tunable, to force the kernel
to always wait for root mount holds, even if the root is already there.

35c46ba5bd loader: biosdisk fix for 2+TB disks
This fix is implementing partition based boundary check for
disk IO and updates disk mediasize (if needed), based on information
from partition table.

As it appeared, the signed int based approach still has corner cases,
and the wrapover based behavior is non-standard.

The idea for this fix is based on two assumptions:

The bug about media size is hitting large (2+TB) disks, lesser disks
hopefully, are not affected.

Large disks are using GPT (which does include information about disk size).
Since our concern is about boot support and boot disks are partitioned,
implementing partition boundaries based IO verification should make the
media size issues mostly disappear.

However, for large disk case, we do have the disk size available from GPT table.
If non-GPT cases will appear, we still can make approximate calculation about
disk size based on defined partition(s), however, this is not the objective
of this patch, and can be added later if there is any need.

This patch does implement disk media size adjustment (if needed) in bd_open(),
and boundary check in bd_realstrategy().

u_int8_t variable to store the result of cpu_get_control().
It should really use a u_int variable, the same way as done for cpu_ident()
in the same function, as both cpuid and control registers are 32-bit..
This issue causes users of identcpu-v4 to incorrectly report things such as
icache status (bit 12 in cpu control register) and basically anything

7a60826b65 loader: bcache read ahead block count should take account the large sectors
The loader bcache is implementing simple read-ahead to boost the cache.
The bcache is built based on 512B block sizes, and the read ahead is attempting
to read number of cache blocks, based on amount of the free bcache space.

However, there are devices using larger sector sizes than 512B, most obviously
the CD media is based on 2k sectors. This means the read-ahead can not be just
random number of blocks, but we should use value suitable also for use with
larger sectors, as for example, with CD devices, we should read multiple of 2KB.
Since the sector size from disk interface is not too reliable, i guess we can
just use "good enough" value, so the implementation is rounding down the read
ahead block count to be multiple of 16.

This means we have covered sector sizes to 8k.

In addition, the update does implement the end of cache marker, to help to
detect the possible memory corruption - I have not seen it happening so far,
but it does not hurt to have the detection mechanism in place.

Small summary
 -------------

o Almost all IPsec releated code was moved into sys/netipsec.
o New kernel modules added: ipsec.ko and tcpmd5.ko. New kernel
  option IPSEC_SUPPORT added. It enables support for loading
  and unloading of ipsec.ko and tcpmd5.ko kernel modules.
o IPSEC_NAT_T option was removed. Now NAT-T support is enabled by
  default. The UDP_ENCAP_ESPINUDP_NON_IKE encapsulation type
  support was removed. Added TCP/UDP checksum handling for
  inbound packets that were decapsulated by transport mode SAs.
  setkey(8) modified to show run-time NAT-T configuration of SA.
o New network pseudo interface if_ipsec(4) added. For now it is
  build as part of ipsec.ko module (or with IPSEC kernel).
  It implements IPsec virtual tunnels to create route-based VPNs.
o The network stack now invokes IPsec functions using special
  methods. The only one header file <netipsec/ipsec_support.h>
  should be included to declare all the needed things to work
  with IPsec.
o All IPsec protocols handlers (ESP/AH/IPCOMP protosw) were removed.
  Now these protocols are handled directly via IPsec methods.
o TCP_SIGNATURE support was reworked to be more close to RFC.
o PF_KEY SADB was reworked:
  - now all security associations stored in the single SPI namespace,
    and all SAs MUST have unique SPI.
  - several hash tables added to speed up lookups in SADB.
  - SADB now uses rmlock to protect access, and concurrent threads
    can do SA lookups in the same time.
  - many PF_KEY message handlers were reworked to reflect changes
    in SADB.
  - SADB_UPDATE message was extended to support new PF_KEY headers:
    SADB_X_EXT_NEW_ADDRESS_SRC and SADB_X_EXT_NEW_ADDRESS_DST. They
    can be used by IKE daemon to change SA addresses.
o ipsecrequest and secpolicy structures were cardinally changed to
  avoid locking protection for ipsecrequest. Now we support
  only limited number (4) of bundled SAs, but they are supported
  for both INET and INET6.
o INPCB security policy cache was introduced. Each PCB now caches
  used security policies to avoid SP lookup for each packet.
o For inbound security policies added the mode, when the kernel does
  check for full history of applied IPsec transforms.
o References counting rules for security policies and security
  associations were changed. The proper SA locking added into xform
  code.
o xform code was also changed. Now it is possible to unregister xforms.
  tdb_xxx structures were changed and renamed to reflect changes in
  SADB/SPDB, and changed rules for locking and refcounting.

c12dbfe608 loader: Implement disk_ioctl() to support DIOCGSECTORSIZE and DIOCGMEDIASIZE.
Need interface to extract information about disk abstraction,
to read disk or partition size depending on the provided argument
and adjust disk size based on information in partition table.

The disk handle from disk_open() has d_offset field to point to
partition start. So we can use this fact to return either whole disk
size or partition size. For this we only need to record partition size
we get from disk_open() anyhow.

In addition, this will also make it possible to adjust the disk media size
based on information from partition table. The problem with disk size is
about some BIOS systems reporting bogus disk size for 2+TB disks, but
since such disks are using GPT partitioning, and GPT does have information
about disk size (alternate LBA + 1), we can use this fact to record disk
size based on partition table.

This patch does exactly this: implements DIOCGSECTORSIZE and DIOCGMEDIASIZE
ioctl, and DIOCGMEDIASIZE will report either disk media size or partition size.

Adds ptable_getsize() call to read partition size in bytes from ptable pointer.
Updates disk_open() to use ptable_getsize() to update mediasize value.

Implements GPT detection function to update ptable size (used by
ptable_getsize()) according to alternate lba (which is location of backup copy
of GPT header table).

9ad221a558 Add tsw_busy support to usb_serial (ucom).
The tty layer uses tsw_busy to poll for busy/idle status of the transmitter
hardware during close() and tcdrain(). The ucom layer defines ULSR_TXRDY and
ULSR_TSRE bits for the line status register; when both are set, the
transmitter is idle. Not all chip drivers maintain those bits in the sc_lsr
field, and if the bits never get set the transmitter will always appear
busy, causing hangs in tcdrain().

These changes add a new sc_flag bit, UCOM_FLAG_LSRTXIDLE. When this flag is
set, ucom_busy() uses the lsr bits to return busy vs. idle state, otherwise
it always returns idle (which is effectively what happened before this
change because tsw_busy wasn't implemented).

For the uftdi chip driver, these changes stop masking out the tx idle bits
when processing the status register (because now they're useful), and it
calls ucom_use_lsr_txbits() to indicate the bits are maintained by the
driver and can be used by ucom_busy().
