a00ec46f52 r237748 continuation: segment-override prefixes are not invalid in long mode
Update DTrace disassembler accordingly.  The code to treat the prefixes
as null prefixes was already in place.
Although in practice compilers seem to generate only cs-prefix for use
in long NOPs, the same treatment is applied to all of cs, ds, es, ss for
consistency.

56b27dd2e7 Add support for the 'invept' and 'invvpid' instructions. Beyond simply
adding appropriate table entries, the assembler had to be adjusted as
these are the first non-SSE instructions to use a 3-byte opcode (and a
mandatory prefix to boot).

56c146fdcb Several fixes to the amd64 disassembler:
- Add generic support for opcodes that are escape bytes used for
  multi-byte opcodes (such as the 0x0f prefix).  Use this to replace
  the hard-coded 0x0f special case and add support for three-byte
  opcodes that use the 0x0f38 prefix.
- Decode all Intel VMX instructions.  invept and invvpid in particular are
  three-byte opcodes that use the 0x0f38 escape prefix.
- Rework how the special 'SDEP' size flag works such that the default
  instruction name (i_name) is the instruction when the data size
  prefix (0x66) is not specified, and the alternate name in i_extra is
  used when the prefix is included.
- Add a new 'ADEP' size flag similar to 'SDEP' except that it chooses
  between i_name and i_extra based on the address size prefix (0x67).
  Use this to fix the decoding for jrcxz vs jecxz which is determined
  by the address size prefix, not the operand size prefix.  Also, jcxz
  is not possible in 64-bit mode, but jrcxz is the default instruction
  for that opcode.
- Add support for handling instructions that have a mandatory 'rep'
  prefix (this means not outputting the 'repe ' prefix until determining
  if it is used as part of an opcode).  Make 'pause' less of a special
  case this way.
- Decode 'cmpxchg16b' and 'cdqe' which are variants of other instructions
  but with a REX.W prefix.

a4e243117e Remove the "funny targets" make check. We no longer need embedded :: targets
to build FreeBSD (they are used in Perl man pages).  We never needed embedded
"!" in targets that I can find.

We got this from OpenBSD and I cannot find any other make that supports
such things -- contrary to their commit message claim: "This behaviour
is also consistent with other versions of make.".

1fb1092d75 Make use of GEOM Gate direct reads feature. This allows HAST to serve
reads with native speed of the underlying provider.
There are three situations when direct reads are not used:
1. Data is being synchronized and synchronization source is the secondary
   node, which means secondary node has more recent data and we should read
   from it.
2. Local read failed and we have to try to read from the secondary node.
3. Local component is unavailable and all I/O requests are served from the
   secondary node.

38de8ef1dd Use correct part of the Master-Key for generating encryption keys.
Before this change the IV-Key was used to generate encryption keys,
which was incorrect, but safe - for the XTS mode this key was unused
anyway and for CBC mode it was used differently to generate IV
vectors, so there is no risk that IV vector collides with encryption
key somehow.

8b8c2303a1 Add the possibility to specify a threshold for the number of negative cache
results required to have the cache return lookup failure.

A new configuration parameter is introduced, which must be set to a value
greater than 1 to activate this feature. The default behavior is unchanged.

The purpose of this change is to allow probes for the existence of an entry
(which are expected to fail), before that entry is added to one of the
queried databases, without the cache returning the stale information from
the probe query until that cache entry expires. If, for example, a new user
account is created after checking that the new account name is available,
the negative cache entry would prevent immediate access to the account.

For that example, the new configuration option

negative-confidence-threshold passwd 2

will require a second negative query result to consider the negative cache
entry for a passwd entry valid, but if the user account has been created
between the queries, then the positive query result from the second query
will be cached and returned.

e5f970ed4a Document RO_RTFREE() macro. 2012-07-04 07:42:12 +00:00
glebius
418a04b467 When ip_output()/ip6_output() is supplied a struct route *ro argument,
it skips FLOWTABLE lookup. However, the non-NULL ro has dual meaning
here: it may be supplied to provide route, and it may be supplied to
store and return to caller the route that ip_output()/ip6_output()
finds. In the latter case skipping FLOWTABLE lookup is pessimisation.

The difference between struct route filled by FLOWTABLE and filled
by rtalloc() family is that the former doesn't hold a reference on
its rtentry. Reference is hold by flow entry, and it is about to
be released in future. Thus, route filled by FLOWTABLE shouldn't
be passed to RTFREE() macro.

- Introduce new flag for struct route/route_in6, that marks route
  not holding a reference on rtentry.
- Introduce new macro RO_RTFREE() that cleans up a struct route
  depending on its kind.
- All callers to ip_output()/ip6_output() that do supply non-NULL
  but empty route should use RO_RTFREE() to free results of
  lookup.
- ip_output()/ip6_output() now do FLOWTABLE lookup always when
  ro->ro_rt == NULL.

77364c7973 Fix panics triggered by older mfiutil binaries run on the new mfi(4) driver.
The new driver changed the size of the mfi_dcmd_frame structure in such a
way that a MFI_IOC_PASSTHRU ioctl from an old amd64 binary is treated as an
MFI_IOC_PASSTHRU32 ioctl in the new driver.  As a result, the user pointer
is treated as the buffer length.  mfi_user_command() doesn't have a bounds
check on the buffer length, so it passes a really big value to malloc()
which panics when it tries to exhaust the kmem_map.  Fix this two ways:
- Only honor MFI_IOC_PASSTHRU32 if the binary has the SV_ILP32 flag set,
  otherwise treat it as an unknown ioctl.
- Add a bounds check on the buffer length passed by the user.  For now
  it fails any user attempts to use a buffer larger than 1MB.

While here, fix a few other nits:
- Remove an unnecessary check for a NULL return from malloc(M_WAITOK).
- Use the ENOTTY errno for invalid ioctl commands instead of ENOENT.
