Extend the support for exempting processes from being killed when swap is

- Add a new protect(1) command that can be used to set or revoke protection

existing descendants of a process as well as future descendants.
- Add a new procctl(2) system call that provides a generic interface for
control operations on processes (as opposed to the debugger-specific
operations provided by ptrace(2)). procctl(2) uses a combination of
idtype_t and an id to identify the set of processes on which to operate
similar to wait6().
- Add a PROC_SPROTECT control operation to manage the protection status
of a set of processes. MADV_PROTECT still works for backwards
compatability.

Change the cap_rights_t type from uint64_t to a structure that we can extend
in the future in a backward compatible (API and ABI) way.

The cap_rights_t represents capability rights. We used to use one bit to
represent one right, but we are running out of spare bits. Currently the new
structure provides place for 114 rights (so 50 more than the previous
cap_rights_t), but it is possible to grow the structure to hold at least 285
rights, although we can make it even larger if 285 rights won't be enough.

The structure definition looks like this:

struct cap_rights {
uint64_t cr_rights[CAP_RIGHTS_VERSION + 2];
};

The initial CAP_RIGHTS_VERSION is 0.

The top two bits in the first element of the cr_rights[] array contain total
number of elements in the array - 2. This means if those two bits are equal to
0, we have 2 array elements.

The top two bits in all remaining array elements should be 0.
The next five bits in all array elements contain array index. Only one bit is
used and bit position in this five-bits range defines array index. This means
there can be at most five array elements in the future.

To define new right the CAPRIGHT() macro must be used. The macro takes two
arguments - an array index and a bit to set, eg.

#define CAP_PDKILL CAPRIGHT(1, 0x0000000000000800ULL)

We still support aliases that combine few rights, but the rights have to belong
to the same array element, eg:

#define CAP_LOOKUP CAPRIGHT(0, 0x0000000000000400ULL)
#define CAP_FCHMOD CAPRIGHT(0, 0x0000000000002000ULL)

#define CAP_FCHMODAT (CAP_FCHMOD | CAP_LOOKUP)

There is new API to manage the new cap_rights_t structure:

cap_rights_t *cap_rights_init(cap_rights_t *rights, ...);
void cap_rights_set(cap_rights_t *rights, ...);
void cap_rights_clear(cap_rights_t *rights, ...);
bool cap_rights_is_set(const cap_rights_t *rights, ...);

bool cap_rights_is_valid(const cap_rights_t *rights);
void cap_rights_merge(cap_rights_t *dst, const cap_rights_t *src);
void cap_rights_remove(cap_rights_t *dst, const cap_rights_t *src);
bool cap_rights_contains(const cap_rights_t *big, const cap_rights_t *little);

Capability rights to the cap_rights_init(), cap_rights_set(),
cap_rights_clear() and cap_rights_is_set() functions are provided by
separating them with commas, eg:

cap_rights_t rights;

cap_rights_init(&rights, CAP_READ, CAP_WRITE, CAP_FSTAT);

There is no need to terminate the list of rights, as those functions are
actually macros that take care of the termination, eg:

#define cap_rights_set(rights, ...) \
__cap_rights_set((rights), __VA_ARGS__, 0ULL)
void __cap_rights_set(cap_rights_t *rights, ...);

Thanks to using one bit as an array index we can assert in those functions that
there are no two rights belonging to different array elements provided
together. For example this is illegal and will be detected, because CAP_LOOKUP
belongs to element 0 and CAP_PDKILL to element 1:

cap_rights_init(&rights, CAP_LOOKUP | CAP_PDKILL);

Providing several rights that belongs to the same array's element this way is
correct, but is not advised. It should only be used for aliases definition.

This commit also breaks compatibility with some existing Capsicum system calls,
but I see no other way to do that. This should be fine as Capsicum is still
experimental and this change is not going to 9.x.

kdump: Decode SOCK_CLOEXEC and SOCK_NONBLOCK in socket() and socketpair().

Add new mmap(2) flags to permit applications to request specific virtual
address alignment of mappings.
- MAP_ALIGNED(n) requests a mapping aligned on a boundary of (1 << n).
Requests for n >= number of bits in a pointer or less than the size of
a page fail with EINVAL. This matches the API provided by NetBSD.
- MAP_ALIGNED_SUPER is a special case of MAP_ALIGNED. It can be used
to optimize the chances of using large pages. By default it will align
the mapping on a large page boundary (the system is free to choose any
large page size to align to that seems best for the mapping request).
However, if the object being mapped is already using large pages, then
it will align the virtual mapping to match the existing large pages in
the object instead.
- Internally, VMFS_ALIGNED_SPACE is now renamed to VMFS_SUPER_SPACE, and
VMFS_ALIGNED_SPACE(n) is repurposed for specifying a specific alignment.
MAP_ALIGNED(n) maps to using VMFS_ALIGNED_SPACE(n), while
MAP_ALIGNED_SUPER maps to VMFS_SUPER_SPACE.
- mmap() of a device object now uses VMFS_OPTIMAL_SPACE rather than
explicitly using VMFS_SUPER_SPACE. All device objects are forced to
use a specific color on creation, so VMFS_OPTIMAL_SPACE is effectively
equivalent.

If the -r option is given we cannot enter capability mode.
The option tells kdump to convert numeric UIDs and GIDs into user and
group names plus to convert times and dates into locallized versions.
This all needs opening various files at various occasions.

MFp4 @229086:

Make use of Capsicum to protect kdump(1), as it might be used to parse data
from untrusted sources:

- Sandbox kdump(1) using capability mode.
- Limit stdin descriptor (where opened file is moved to) to only
CAP_READ and CAP_FSTAT rights.
- Limit stdout descriptor to only CAP_WRITE, CAP_FSTAT and CAP_IOCTL.
Plus limit allowed ioctls to TIOCGETA only, which is needed for
isatty() to work.
- Limit stderr descriptor to only CAP_WRITE and CAP_FSTAT. In addition
if the -s option is not given, grant CAP_IOCTL right, but allow for
TIOCGWINSZ ioctl only, as we need screen width to dump the data.
- Before entering capability mode call catopen("libc", NL_CAT_LOCALE),
which opens message catalogs and caches data, so that strerror(3)

Merge Capsicum overhaul:

- Capability is no longer separate descriptor type. Now every descriptor

- The cap_new(2) system call is left, but it is no longer documented and
should not be used in new code.

- The new syscall cap_rights_limit(2) should be used instead of
cap_new(2), which limits capability rights of the given descriptor
without creating a new one.

- The cap_getrights(2) syscall is renamed to cap_rights_get(2).

- If CAP_IOCTL capability right is present we can further reduce allowed
ioctls list with the new cap_ioctls_limit(2) syscall. List of allowed
ioctls can be retrived with cap_ioctls_get(2) syscall.

- If CAP_FCNTL capability right is present we can further reduce fcntls
that can be used with the new cap_fcntls_limit(2) syscall and retrive
them with cap_fcntls_get(2).

This patch adds a new ktrace(2) record type, KTR_STRUCT, whose payload
consists of the null-terminated name and the contents of any structure
you wish to record. A new ktrstruct() function constructs and emits a
KTR_STRUCT record. It is accompanied by convenience macros for struct
stat and struct sockaddr.

In kdump(1), KTR_STRUCT records are handled by a dispatcher function
that runs stringent sanity checks on its contents before handing it
over to individual decoding funtions for each type of structure.
Currently supported structures are struct stat and struct sockaddr for
the AF_INET, AF_INET6 and AF_UNIX families; support for AF_APPLETALK
and AF_IPX is present but disabled, as I am unable to test it properly.

Since 's' was already taken, the letter 't' is used by ktrace(1) to
enable KTR_STRUCT trace points, and in kdump(1) to enable their
decoding.

Revert CLEANDEPFILES commit per ru@'s request; it does not really solve
the problem. The correct fix will follow.

Normally, when a header file is removed from the build (as i4b headers
were recently), a simple 'make cleandepend; make depend' is sufficient
to keep the tree buildable after a cvs update when doing incremental
builds.

However, kdump and truss use a script which searches for header files
that define ioctls, and generates C code that includes them. This
script will usually not need updating when a header file is removed,
so the normal dependency mechanism will not realize that it needs to
be re-run. One is therefore left with code that references dead files
but will only be removed by a full 'make clean', which defeats the
purpose of incremental builds.

To work around this, modify the cleandepend target in bsd.dep.mk to
also remove any files listed in a new variable named CLEANDEPFILES,

- Don't install netatm include files
- Disconnect netatm command line management tools
- Don't build libatm
- Don't include ATM parts in rescue or sysinstall
- Don't install sample configuration files and documents
- Don't build kernel support as a module or in NOTES
- Don't build netgraph wrapper nodes for netatm

Add sockipprotoname() function. Decode the third parameter (protocol)
of a socket() call with sockipprotoname() if the first parameter (domain)
is PF_INET or PF_INET6.

Old parsing behavior before this change:
ping6 CALL socket(PF_INET6,SOCK_RAW,0x3a)

New behavior after this change:
ping6 CALL socket(PF_INET6,SOCK_RAW,IPPROTO_ICMPV6)

Generate sockdomainname() function with auto_if_type() instead
of auto_or_type.

The old parsing code would incorrectly decode a socket() call in the
ping6 program as:
CALL socket(PF_PUP|PF_ECMA|PF_APPLETALK|PF_COIP|PF_SIP,SOCK_DGRAM,0)

The new parsing code decodes the same socket() call as:
CALL socket(PF_INET6,SOCK_DGRAM,0)

Add auto_if_type() function, which is similar to auto_switch_type().
However, auto_if_type() uses if/else statements in C instead
of a single switch statement, when mapping an integer value to
a #define. For certain cases where multiple #define constants
alias to a single integer value, auto_if_type() makes things easier
to parse than auto_switch_type().

The second argument (type) to socket(2) is an enum, not a bitmask, so parse
it as an enum.

If an SCTP SOCK_SEQPACKET socket was opened, kdump would display this
wrong output:
socket(PF_INET,SOCK_STREAM|SOCK_RDM|SOCK_SEQPACKET,0x84)

instead of this correct output:
socket(PF_INET,SOCK_SEQPACKET,0x84)

Two enhancements for kdump.
1) add a "-p pid", which is rather useful for selecting a single pid in
a combined trace file (eg: with ktrace -i).
2) display binary genio data in a more precise format.

Add a default case that just outputs a new line for the case of an
unknown header type.

Teach kdump(8) to handle events marked with KTR_DROP. If a record has
KTR_DROP set in its header, then we output an extra line to stdout to
indicate that events were dropped between the previous record and this
record. It is a bit trickier because we need to always notify the user
if events are dropped even if KTR_DROP is set on a record of a type that
we aren't interested in since kdump(8) doesn't know if the dropped events
were of the types that the user has requested. To avoid outputting
multiple events dropped notices in between actual event logs, a state
variable is set whenever a drop is logged and cleared whenever an actual
record is output.

Traverse ${DESTDIR}/usr/include in lexographical order.
This should fix problems reported recently on -current.

Rewrite of the CAM error recovery code.

Some of the major changes include:

- The SCSI error handling portion of cam_periph_error() has
been broken out into a number of subfunctions to better
modularize the code that handles the hierarchy of SCSI errors.
As a result, the code is now much easier to read.

- String handling and error printing has been significantly
revamped. We now use sbufs to do string formatting instead
of using printfs (for the kernel) and snprintf/strncat (for
userland) as before.

There is a new catchall error printing routine,
cam_error_print() and its string-based counterpart,
cam_error_string() that allow the kernel and userland
applications to pass in a CCB and have errors printed out
properly, whether or not they're SCSI errors. Among other
things, this helped eliminate a fair amount of duplicate code
in camcontrol.

We now print out more information than before, including
the CAM status and SCSI status and the error recovery action
taken to remedy the problem.

- sbufs are now available in userland, via libsbuf. This
change was necessary since most of the error printing code
is shared between libcam and the kernel.

- A new transfer settings interface is included in this checkin.
This code is #ifdef'ed out, and is primarily intended to aid
discussion with HBA driver authors on the final form the
interface should take. There is example code in the ahc(4)
driver that implements the HBA driver side of the new
interface. The new transfer settings code won't be enabled
until we're ready to switch all HBA drivers over to the new
interface.

src/Makefile.inc1,
lib/Makefile: Add libsbuf. It must be built before libcam,
since libcam uses sbuf routines.

libcam/Makefile: libcam now depends on libsbuf.

libsbuf/Makefile: Add a makefile for libsbuf. This pulls in the
sbuf sources from sys/kern.

bsd.libnames.mk: Add LIBSBUF.

camcontrol/Makefile: Add -lsbuf. Since camcontrol is statically
linked, we can't depend on the dynamic linker
to pull in libsbuf.

camcontrol.c: Use cam_error_print() instead of checking for
CAM_SCSI_STATUS_ERROR on every failed CCB.

sbuf.9: Change the prototypes for sbuf_cat() and
sbuf_cpy() so that the source string is now a
const char *. This is more in line wth the
standard system string functions, and helps
eliminate warnings when dealing with a const
source buffer.

Fix a typo.

cam.c: Add description strings for the various CAM
error status values, as well as routines to
look up those strings.

Add new cam_error_string() and
cam_error_print() routines for userland and
the kernel.

cam.h: Add a new CAM flag, CAM_RETRY_SELTO.

Add enumerated types for the various options
available with cam_error_print() and
cam_error_string().

cam_ccb.h: Add new transfer negotiation structures/types.

Change inq_len in the ccb_getdev structure to
be "reserved". This field has never been
filled in, and will be removed when we next
bump the CAM version.

cam_debug.h: Fix typo.

cam_periph.c: Modularize cam_periph_error(). The SCSI error
handling part of cam_periph_error() is now
in camperiphscsistatuserror() and
camperiphscsisenseerror().

In cam_periph_lock(), increase the reference
count on the periph while we wait for our lock
attempt to succeed so that the periph won't go
away while we're sleeping.

cam_xpt.c: Add new transfer negotiation code. (ifdefed
out)

Add a new function, xpt_path_string(). This
is a string/sbuf analog to xpt_print_path().

scsi_all.c: Revamp string handing and error printing code.
We now use sbufs for much of the string
formatting code. More of that code is shared
between userland the kernel.

scsi_all.h: Get rid of SS_TURSTART, it wasn't terribly
useful in the first place.

Add a new error action, SS_REQSENSE. (Send a
request sense and then retry the command.)
This is useful when the controller hasn't
performed autosense for some reason.

scsi_cd.c,
scsi_da.c,
scsi_pt.c,
scsi_ses.c: SF_RETRY_SELTO -> CAM_RETRY_SELTO. Selection
timeouts shouldn't be covered by a sense flag.

scsi_pass.[ch]: SF_RETRY_SELTO -> CAM_RETRY_SELTO.

Get rid of the last vestiges of a read/write
interface.

libkern/bsearch.c,
sys/libkern.h,
conf/files: Add bsearch.c, which is needed for some of the
new table lookup routines.

aic7xxx_freebsd.c: Define AHC_NEW_TRAN_SETTINGS if
CAM_NEW_TRAN_CODE is defined.

sbuf.h,
subr_sbuf.c: Add the appropriate #ifdefs so sbufs can
compile and run in userland.

Change sbuf_printf() to use vsnprintf()
instead of kvprintf(), which is only available
in the kernel.

Change the source string for sbuf_cpy() and
sbuf_cat() to be a const char *.

Add __BEGIN_DECLS and __END_DECLS around
function prototypes since they're now exported
to userland.
