d4a115af56 Move siftr-related definitions out of tcp.d and into a separate library
which declares a dependency on siftr(4). This is necessitated by a
reference to struct pkt_node, which is defined in siftr(4): otherwise,
dtrace(1) will return an error during startup if siftr.ko is not loaded.

f65e699c36 As dtrace(1) processes D libraries under /usr/lib/dtrace, the compiler may
return an error if one of the depends_on directives in a library is not
satisfied. In this case, libdtrace is supposed to ignore the library and
carry on. However, the remainder of the library may still be buffered by
the lexer, causing libdtrace to erroneously continue processing it on the
next call to yyparse(). Fix this by explicitly flushing the input buffer
each time the compiler state is reset.

3e5645b78f ctf_add_type(): when looking up an integer or floating point type in the
list of pending dynamic type definitions, a match on the type name is not
sufficient - we need to compare the type encodings as well. For example,
bitfields have their own distinct type definitions which share the name of
the underlying integer type, and these types aren't generally
interchangeable.

This bug was causing the following libdtrace error when attempting to trace
the th_flags member of a struct tcphdr:
  cg: bad field: off 104 type <32877> bits 539620016

41aeaf2a30 Replace dtest.pl, the upstream DTrace test suite harness, with a shell
script. This reimplementation is much simpler than dtest.pl and is more
amenable to being run under Kyua - dtest.pl writes error output to a
temporary directory that is deleted when the run finishes, making it hard
to debug test failures. This change also removes the test suite's dependency
on perl.

f810bf0eaf When copying a type from a source CTF container to a destination container,
ctf_add_type() first performs a by-name lookup of the type in the
destination container. If this lookup returns a forward declaration for an
enum, struct, or union, reset dst_type back to CTF_ERR, indicating that the
source type is not in fact present in the destination container. This
ensures that ctf_add_type() will also search the destination container's
dynamic type list for the source type.

Without this change, a pair of mutually recursive struct definitions could
cause infinite recursion in ctf_add_type() if the destination container
only contained forward declarations for the struct types: ctf_add_type()
recursively calls itself on each struct member's type, and the forward
declarations meant that the dynamic type list search would be skipped.

b0ee912984 CTF containers use the ctf_dtoldid field as a threshold type index which
indicates the range of type indices which have been committed to the
container by ctf_update(). However, the top bit of the dtd_type field is
not part of the type index; rather, it is a flag used to indicate that the
corresponding CTF container is a parent. This is why the maximum CTF type
index is 2^15 - 1 rather than 2^16 - 1. Therefore, this flag must be masked
off (using the CTF_TYPE_TO_INDEX macro) when comparing a type index with the
ctf_dtoldid field of a container.

This bug was causing libctf to erroneously free committed type definitions
in ctf_discard(). libdtrace holds some references to such types, resulting
in a use-after-free.

4ddbe5ac37 Add infrastructure to integrate the DTrace test suite with Kyua.
For each test category, we generate a script containing ATF test cases for
the tests under that category. Each test case simply runs dtest.pl (the
upstream test harness) with the corresponding test files. The exclude.sh
script is used to record info about tests which should be skipped or are
expected to fail; it is used to generate atf_skip and atf_expect_fail calls.
The genmakefiles.sh script can be used to regenerate the test makefiles when
new tests are brought it from upstream.

The test suite is currently not connected to the build as there is a small
number of lingering test issues which still need to be worked out. In the
meantime however, the test suite can be easily built and installed
manually from cddl/usr.sbin/dtrace/tests.

03a5f9f0fd Remove drti.o's dependency on libelf. This makes it possible to add DTrace
probes to userland programs and libraries without also needing to link
libelf.

dtrace -G places the __SUNW_dof symbol at the beginning of the DOF (DTrace
probe and provider metdata) section in the generated object file; drti.o
now just uses this symbol to locate the section. A complication occurs
when multiple dtrace-generated object files are linked together, since the
__SUNW_dof symbol defined in each file is global. This is handled by
using objcopy(1) to convert __SUNW_dof to a local symbol once drti.o has
been linked with the generated object file. Upstream, this is done using a
linker feature not present in GNU ld.

Introduce a seperate phase to list all unavailable pools when listing

Introduce cb_unavail to upgrade_cbdata_t which enables the final

available pools where up-to-date on version / features.

Correct the type of upgrade_cbdata_t.cb_first from int -> boolean_t.

Change the pool iteration when upgrading named pools to include
unavailable pools and update upgrade_one so it doesn't try to upgrade
unavailable pools but warns about them. This allows the correct error
to be displayed as well as upgrades with available and unavailable
pools intermixed to partially complete.

af62c4ddd0 DTrace imposes a 128-byte limit on the length of the function component of
a probe name. When dtrace -G builds up a DOF section for the specified
provider(s), the probe function names are truncated to fit in this limit.
The DOF is later used to build the symbol table for the generated object
file, so the table can end up with truncated references, causing link
errors.

Instead of potentially truncating symbol table entries, write the full
function name to the DOF string table and allow the kernel to enforce the
128-byte function name limit when a process attempts to load its DOF.

Initialize tqent_flags in the userland taskq implementation.  Without

The problem is that tqent_flags is never initialized in the userland
implementation while the kernel one does initialize it.  Without proper
initialization, the flag may have its lowest bit set, making it treated
as TQENT_FLAG_PREALLOC and never removing taskq_ent_t from tq_freelist.

41da933c87 Hook up support for userland CTF support in DTrace. This required some
modifications to libproc to support fetching the CTF info for a given file.

With this change, dtrace(1) is able to resolve type info for function and
USDT probe arguments, and function return values. In particular, the args[n]
syntax should now work for referencing arguments of userland probes,
provided that the requisite CTF info is available.

The uctf tests pass if the test programs are compiled with CTF info. The
current infrastructure around the DTrace test suite doesn't support this
yet.

Instead of asserting all zio's be properly aligned, only assert
on the logical ones.

Cap uberblocks at 8k, otherwise with ashift=17, there would be
only one uberblock.

This fixes a problem that zdb would trip assert on pools with
ashift >= 0xe (8k).

While there, also change the code so it only attempt to condense
space map unless the uncondensed size consumes greater than
zfs_metaslab_condense_block_threshold blocks.

7079d5877c MFV r268714:
Improve extreme rewind import.

When doing an "extreme rewind" import ("zpool import -XF"), we attempt
to verify all data in the pool, essentially scrubbing the entire pool.
The problem is that spa_load_verify_cb() issues an unbounded number of
concurrent scrub i/os.  This can lead to all of memory being used for
these zio's, wedging the system. Like normal scrub, we need to put a
cap on the number of outstanding i/os, and have the traverse thread
block when we reach this cap.

For this purpose the cap can be very large (10,000) to optimize the
elevator algorithm.  Three kernel tunables have been added:

	vfs.zfs.spa_load_verify_maxinflight
	vfs.zfs.spa_load_verify_metadata
	vfs.zfs.spa_load_verify_data

The latter two tunables controls whether metadata and/or user data
when doing extreme rewind.

Make 'zpool import -T' imply scrub.

Make zpool import -T <txg> accept hexadecimal values for the txg when
prefixed with 0x.

Skip txg's for which there is no uberblock when doing extreme rewind.

Skip reading all user data twice by skipping prefetches when doing
extreme rewinds as we do not access via the ARC.

Illumos issues:
  4970 need controls on i/o issued by zpool import -XF
  4971 zpool import -T should accept hex values
  4972 zpool import -T implies extreme rewind, and thus a scrub
  4973 spa_load_retry retries the same txg
  4974 spa_load_verify() reads all data twice

Use reserved space for ZFS administrative commands.

We reserve 1/2^spa_slop_shift = 1/32 or 3.125% of pool space (or 32MB at
least) for system use.  Most ZPL operations, e.g. write(2), creat(2), will
fail with ENOSPC if we fall below this.

Certain operations, e.g. file removal and most administrative actions,
still permitted until half of the slop space is used.  This would allow
users to use these operations to free up space in the pool when pool is
close to full but half of slop space is still free.

A very restricted set of operations that frees up space or change quota
are always permitted, regardless of the amount of free space.

2bdf7f79bc MFV r266766:
Add a new zfs property, "redundant_metadata" which can have values "all" or
"most".  The default will be "all", which is the current behavior.  When set
to all, ZFS stores an extra copy of all metadata.  If a single on-disk block
is corrupt, at worst a single block of user data (which is recordsize bytes
long) can be lost.

Setting to "most" will cause us to only store 1 copy of level-1 indirect
blocks of user data files.  This can improve performance of random writes,
because less metadata has to be written.  In practice,  at worst about
100 blocks (of recordsize bytes each) of user data can be lost if a single
on-disk block is corrupt.

The exact behavior of which metadata blocks are stored redundantly may change
in future releases.

dtrace(1) can now set a breakpoint in the victim process after it has
registered its DOF table(s) with the kernel. r_debug_state cannot be used
for this purpose since it is called before DOF is made available, in which
case dtrace(1) cannot create USDT probes before the program begins

537650f54d Add property and sysctl to control how ZVOLs are exposed to OS.
New ZFS property volmode and sysctl vfs.zfs.vol.mode allow switching ZVOL
between three modes:
 geom -- existing fully functional behavior (default);
 dev -- exposing volumes only as raw disk device file in devfs;
 none -- not exposing volumes outside ZFS.

The "dev" mode is less functional (can't be partitioned, mounted, etc),
but it is faster, and in some scenarios with untrusted consumers safer.
It can be useful for NAS, VM block storages, etc.
The "none" mode may be convenient for backup servers, etc. that don't
need direct data access.

Due to the way ZVOL is integrated with main ZFS code, those property
and sysctl are checked only during pool import and volume creation.

2d084599da Add caveat to zpool manpage indicating that we do not automatically activate
hot spares. This should be MFC'd to all STABLE branches.

Upon the availability of zfsd, the zpool manpage on relevant branches should
be updated to remove this caveat and document hot spare's reliance on zfsd.

9a5be1a0d8 dtrace: remove unexplained 16MB limitation from dt_alloc/dt_zalloc
The limitation was introduced in r178556 without any note or comment.
It seems pretty artificial and now it leads to problems like the following:
  $ dtrace -x bufsize=17m -n ...
  dtrace: processing aborted: Memory allocation failure
OpenSolaris and illumos never had this limitation.

d32f014939 Clang 3.4 will sometimes emit DIE for struct/union member before
emitting the DIE for the type of that member. ctfconvert can not
handle this properly and will calculate a wrong member bit offset.
Same struct/union type from different .o file will be treated as
different types when their member bit offsets are different, and
gets added/merged multiple times. This will in turn cause many other
structs/pointers/typedefs that refer to the duplicated struct/union
gets added/merged multiple times and eventually causes numerous
duplicated CTF types in the kernel.debug file.

The simple workaround here is to make use of DW_AT_byte_size attribute
of the member DIE to calculate the bits occupied by the member's type,
without actually resolving the type.

1391789ee2 If function die_name() finds a DIE without a name, set its name to

like GCC could generate DW_TAG_base_type DIE without a name.

internally set all the unnamed DIE's name to "__anon__".

illumos/illumos-gate@5aeb94743e

Essentially FreeBSD taskqueues already operate in a mode that
was added to Illumos with taskq_dispatch_ent change.
We even exposed the superior FreeBSD interface as taskq_dispatch_safe.
Now we just rename taskq_dispatch_safe to taskq_dispatch_ent and
struct struct ostask to taskq_ent_t, so that code differences will be
minimal.

After this change sys/cddl/compat/opensolaris/sys/taskq.h header is no

e572bc11ec Add a function, memstr, which can be used to convert a buffer of
null-separated strings to a single string. This can be used to print the
full arguments of a process using execsnoop (from the DTrace toolkit) or
with the following one-liner:

dtrace -n 'syscall::execve:return {trace(curpsinfo->pr_psargs);}'

Note that this relies on the process arguments being cached via the struct
proc, which means that it will not work for argvs longer than
kern.ps_arg_cache_limit. However, the following rather non-portable
script can be used to extract any argv at exec time:

fbt::kern_execve:entry
{
    printf("%s", memstr(args[1]->begin_argv, ' ',
        args[1]->begin_envv - args[1]->begin_argv));
}

The debug.dtrace.memstr_max sysctl limits the maximum argument size to
memstr(). Thanks to Brendan Gregg for helpful comments on freebsd-dtrace.
