New FreeBSD snapshots and virtual machine disk images (20130818 r254497)

Mon Aug 19 19:49:50 UTC 2013

New FreeBSD development branch installation ISOs and virtual machine
disk images have been uploaded to the FTP mirrors.

Subversion logs since the last set of snapshots attached to this
email.

As with any development branch, the installation snapshots are not
intended for use on production systems.  We do, however, encourage
testing on non-production systems as much as possible.

If tracking the stable/9 branch or planning to upgrade systems to
9.2-RELEASE, testing the stable/9 snapshots is strongly encouraged
so that potential problems may be found and fixed before the release.

These may be found in the normal releases/ directory of FTP:

    ftp://ftp.FreeBSD.org/pub/FreeBSD/releases/ISO-IMAGES/

Important note: non-x86 snapshots are generated in a cross-build
environment, not natively built on their respective architectures.

Checksums for the installation ISOs and the VM disk images follow at
the end of this email.

=== Installation ISOs ===

bootonly.iso, disc1.iso, and memstick.img images are available for:

o 10.0-CURRENT amd64
o 10.0-CURRENT i386
o 10.0-CURRENT ia64
o 10.0-CURRENT powerpc
o 10.0-CURRENT powepc64
o 10.0-CURRENT sparc64
o 9.2-PRERELEASE amd64
o 9.2-PRERELEASE i386
o 9.2-PRERELEASE ia64
o 9.2-PRERELEASE powerpc
o 9.2-PRERELEASE powerpc64
o 9.2-PRERELEASE sparc64

Please note that the 9.2-PRERELEASE snapshots are generated from the
stable/9 branch, not what will eventually be 9.2-RELEASE.

Snapshots may be downloaded from the corresponding architecture
directory from:

    ftp://ftp.freebsd.org/pub/FreeBSD/snapshots/ISO-IMAGES/

Please be patient if your local FTP mirror has not yet caught
up with the changes.

Problems, bug reports, or regression reports should be reported
through the GNATS PR system or the appropriate mailing list, such
as -current@ or -stable@ .

=== Virtual Machine Disk Images ===

VM disk images are available for the following FreeBSD branches for
the amd64 and i386 architectures:

  o 10.0-CURRENT amd64
  o 10.0-CURRENT i386
  o 9.2-PRERELEASE amd64
  o 9.2-PRERELEASE i386

Disk images may be downloaded from the following URL (or any of the
FreeBSD FTP mirrors):

    ftp://ftp.freebsd.org/pub/FreeBSD/snapshots/VM-IMAGES/Latest/

Images are available in the following disk image formats:

    - QCOW2

Update nvi-1.79 to 2.1.1-4334a8297f

This is the gsoc-2011 project to clean up and backport multibyte support
from other nvi forks in a form we can use.

USE_WIDECHAR is on unless building for the rescue crunchgen. This should
allow editing in the native locale encoding.

USE_ICONV depends on make.conf having 'WITH_ICONV=YES' for now.  This
adds the ability to do things like edit a KOI8-R file while having $LANG
set to (say) en_US.UTF-8.  iconv is used to transcode the characters for
display.

Other points:
* It uses gencat and catopen/etc instead of homegrown msg catalog stuff.
* A lot of stuff has been trimmed out, eg: the perl and tcl bindings which
  we could never use in base anyway.
* It uses ncursesw when in widechar mode.  This could be interesting.

Add read-only support for extents in ext2fs.

Basic support for extents was implemented by Zheng Liu as part
of his Google Summer of Code in 2010. This support is read-only
at this time.

In addition to extents we also support the huge_file extension
for read-only purposes. This works nicely with the additional
support for birthtime/nanosec timestamps and dir_index that
have been added lately.

The implementation may not work for all ext4 filesystems as
it doesn't support some features that are being enabled by
default on recent linux like flex_bg. Nevertheless, the feature
should be very useful for migration or simple access in
filesystems that have been converted from ext2/3 or don't use
incompatible features.

Special thanks to Zheng Liu for his dedication and continued
work to support ext2 in FreeBSD.

Update PCI drivers to no longer look at the MEMIO-enabled bit in the PCI
command register.  The lazy BAR allocation code in FreeBSD sometimes
disables this bit when it detects a range conflict, and will re-enable
it on demand when a driver allocates the BAR.  Thus, the bit is no longer
a reliable indication of capability, and should not be checked.  This
results in the elimination of a lot of code from drivers, and also gives
the opportunity to simplify a lot of drivers to use a helper API to set
the busmaster enable bit.

This changes fixes some recent reports of disk controllers and their
associated drives/enclosures disappearing during boot.

FreeBSD's DTrace implementation has a few problems with respect to handling
probes declared in a kernel module when that module is unloaded. In
particular,

* Unloading a module with active SDT probes will cause a panic. [1]
* A module's (FBT/SDT) probes aren't destroyed when the module is unloaded;
  trying to use them after the fact will generally cause a panic.

This change fixes both problems by porting the DTrace module load/unload
handlers from illumos and registering them with the corresponding
EVENTHANDLER(9) handlers. This allows the DTrace framework to destroy all
probes defined in a module when that module is unloaded, and to prevent a
module unload from proceeding if some of its probes are active. The latter
problem has already been fixed for FBT probes by checking lf->nenabled in
kern_kldunload(), but moving the check into the DTrace framework generalizes
it to all kernel providers and also fixes a race in the current
implementation (since a probe may be activated between the check and the
call to linker_file_unload()).

Additionally, the SDT implementation has been reworked to define SDT
providers/probes/argtypes in linker sets rather than using SYSINIT/SYSUNINIT
to create and destroy SDT probes when a module is loaded or unloaded. This
simplifies things quite a bit since it means that pretty much all of the SDT
code can live in sdt.ko, and since it becomes easier to integrate SDT with
the DTrace framework. Furthermore, this allows FreeBSD to be quite flexible
in that SDT providers spanning multiple modules can be created on the fly
when a module is loaded; at the moment it looks like illumos' SDT
implementation requires all SDT probes to be statically defined in a single
kernel table.

The iconv in libc did two things - implement the standard APIs, the GNU
extensions and also tried to be link time compatible with ports libiconv.
This splits that functionality and enables the parts that shouldn't
interfere with the port by default.

WITH_ICONV (now on by default) - adds iconv.h, iconv_open(3) etc.
WITH_LIBICONV_COMPAT (off by default) adds the libiconv_open etc API, linker
symbols and even a stub libiconv.so.3 that are good enough to be able
to 'pkg delete -f libiconv' on a running system and reasonably expect it
to work.

I have tortured many machines over the last few days to try and reduce
the possibilities of foot-shooting as much as I can.  I've successfully
recompiled to enable and disable the libiconv_compat modes, ports that use
libiconv alongside system iconv etc.  If you don't enable the
WITH_LIBICONV_COMPAT switch, they don't share symbol space.

This is an extension of behavior on other system.  iconv(3) is a standard
libc interface and libiconv port expects to be able to run alongside it on
systems that have it.

ieee80211_rate2plcp() and ieee80211_rate2phytype() are both pre-11n
routines and thus assert if one passes in a rate code with the
high bit set.

Since the high bit can indicate either IEEE80211_RATE_BASIC or
IEEE80211_RATE_MCS, it's up to the caller to determine whether
the rate is 11n or not, and either mask out the BASIC bit, or
call a different function.

(Yes, this does mean that net80211 should grow 11n-aware rate2phytype()
and rate2plcp() functions..)

This may need to happen for the other drivers - it's currently only
done (now) for iwn(4) and bwi(4).

Define ext2fs local types and use them.

Add definitions for e2fs_daddr_t, e4fs_daddr_t in addition
to the already existing e2fs_lbn_t and adjust them for ext4.
Other than making the code more readable these changes should
fix problems related to big filesystems.

Setting the proper types can be tricky so the process was
helped by looking at UFS. In our implementation, logical block
numbers can be negative and the code depends on it. In ext2,
block numbers are unsigned so it is convenient to keep
e2fs_daddr_t unsigned and use the complete 32 bits. In the
case of e4fs_daddr_t, while the value should be unsigned, for
ext4 we only need to support 48 bits so preserving an extra
bit from the sign is not an issue.

While here also drop the ext2_setblock() prototype that was
never used.

reports of its impending demise were removed in 2009 (r199257).

However, in 1996 (r16117) system(3) was switched from vfork(2) to
fork(2) based partly on this.  Switch back to vfork(2).  This has a
dramatic effect in cases of extreme mmap use - such as excessive
abuse (500+) of shared libraries.

Improve pageout flow control to wakeup more frequently and do less work while
maintaining better LRU of active pages.

 - Change v_free_target to include the quantity previously represented by
   v_cache_min so we don't need to add them together everywhere we use them.
 - Add a pageout_wakeup_thresh that sets the free page count trigger for
   waking the page daemon.  Set this 10% above v_free_min so we wakeup before
   any phase transitions in vm users.
 - Adjust down v_free_target now that we're willing to accept more pagedaemon
   wakeups.  This means we process fewer pages in one iteration as well,
   leading to shorter lock hold times and less overall disruption.
 - Eliminate vm_pageout_page_stats().  This was a minor variation on the
   PQ_ACTIVE segment of the normal pageout daemon.  Instead we now process
   1 / vm_pageout_update_period pages every second.  This causes us to visit
   the whole active list every 60 seconds.  Previously we would only maintain
   the active LRU when we were short on pages which would mean it could be
   woefully out of date.

Fix several performance related issues in the new NFS server's
DRC for NFS over TCP.
- Increase the size of the hash tables.
- Create a separate mutex for each hash list of the TCP hash table.
- Single thread the code that deletes stale cache entries.
- Add a tunable called vfs.nfsd.tcphighwater, which can be increased
  to allow the cache to grow larger, avoiding the overhead of frequent
  scans to delete stale cache entries.
  (The default value will result in frequent scans to delete stale cache
   entries, analagous to what the pre-patched code does.)
- Add a tunable called vfs.nfsd.cachetcp that can be used to disable
  DRC caching for NFS over TCP, since the old NFS server didn't DRC cache TCP.
It also adjusts the size of nfsrc_floodlevel dynamically, so that it is
always greater than vfs.nfsd.tcphighwater.

For UDP the algorithm remains the same as the pre-patched code, but the
tunable vfs.nfsd.udphighwater can be used to allow the cache to grow
larger and reduce the overhead caused by frequent scans for stale entries.
UDP also uses a larger hash table size than the pre-patched code.

Change the queue of locks in kern_rangelock.c from holding lock requests in
the order that they arrive, to holding
(a) granted write lock requests, followed by
(b) granted read lock requests, followed by
(c) ungranted requests, in order of arrival.

This changes the stopping condition for iterating through granted locks to
see if a new request can be granted: When considering a read lock request,
we can stop iterating as soon as we see a read lock request, since anything
after that point is either a granted read lock request or a request which
has not yet been granted.  (For write lock requests, we must still compare
against all granted lock requests.)

For workloads with R parallel reads and W parallel writes, this improves
the time spent from O((R+W)^2) to O(W*(R+W)); i.e., heavy parallel-read
workloads become significantly more scalable.

No statistically significant change in buildworld time has been measured,
but synthetic tests of parallel 'dd > /dev/null' and 'openssl enc >/dev/null'
with the input file cached yield dramatic (up to 10x) improvement with high
(up to 128 processes) levels of parallelism.

Change the way that unmapped I/O capability is advertised.

The previous method was to set the D_UNMAPPED_IO flag in the cdevsw
for the driver.  The problem with this is that in many cases (e.g.
sa(4)) there may be some instances of the driver that can handle
unmapped I/O and some that can't.  The isp(4) driver can handle
unmapped I/O, but the esp(4) driver currently cannot.  The cdevsw
is shared among all driver instances.

So instead of setting a flag on the cdevsw, set a flag on the cdev.
This allows drivers to indicate support for unmapped I/O on a
per-instance basis.

sys/conf.h:	Remove the D_UNMAPPED_IO cdevsw flag and replace it
		with an SI_UNMAPPED cdev flag.

kern_physio.c:	Look at the cdev SI_UNMAPPED flag to determine
		whether or not a particular driver can handle
		unmapped I/O.

geom_dev.c:	Set the SI_UNMAPPED flag for all GEOM cdevs.
		Since GEOM will create a temporary mapping when
		needed, setting SI_UNMAPPED unconditionally will
		work.

		Remove the D_UNMAPPED_IO flag.

nvme_ns.c:	Set the SI_UNMAPPED flag on cdevs created here
		if NVME_UNMAPPED_BIO_SUPPORT is enabled.

vfs_aio.c:	In aio_qphysio(), check the SI_UNMAPPED flag on a
		cdev instead of the D_UNMAPPED_IO flag on the cdevsw.

sys/param.h:	Bump __FreeBSD_version to 1000045 for the switch from
		setting the D_UNMAPPED_IO flag in the cdevsw to setting
		SI_UNMAPPED in the cdev.

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.

Handle command retries for commands originating at the mmc layer, and
ensure that all such commands have a non-zero retry count except for those
that are expected to fail (for example, because they are used to probe for
feature support).

While it is possible to pass a retry count down to the hardware driver in
the command request structure, no hardware driver currently implements any
retry logic.  The hardware doesn't know much about the context of a single
request, so it makes more sense to handle retries at a layer that does.

This adds retry loops to the mmc_wait_for_cmd() and mmc_wait_for_app_cmd()
functions.  These functions are the gateway from other code within mmc.c
to the hardware.  App commands are a sequence of two commands and a retry
has to rerun both of them in order, so it needs its own retry loop.

Retry looping is specifically NOT implemented in mmc_wait_for_request()
because it is the gateway for children on the bus, and they have to
implement their own retry logic depending on what makes sense for them.

libc: Access _logname_valid more efficiently.

The variable _logname_valid is not exported via the version script;
therefore, change C and i386/amd64 assembler code to remove indirection
(which allowed interposition). This makes the code slightly smaller and
faster.

Also, remove #define PIC_GOT from i386/amd64 in !PIC mode. Without PIC,
there is no place containing the address of each variable, so there is no
possible definition for PIC_GOT.

Bump up the maximum addressable memory on amd64 systems from 1TB to 4TB.
Bump up the KVA size proportionally from 512GB to 2TB.

The number of page table pages used by the direct map is now calculated at
run time based on 'Maxmem'. This means the small memory systems will not
see any additional tax in terms of page table pages for the direct map.

However all amd64 systems, regardless of the memory size, will use 3 more
pages to accomodate the bump in the KVA size.

Add a "translated type" argument to SDT_PROBE_ARGTYPE() and add some macros
which allow one to define SDT probes that specify translated types. The idea
is to make it easy to write SDT probe definitions that can work across
multiple operating systems. In particular, this makes it possible to port
illumos SDT probes to FreeBSD without changing their argument types, so long
as the appropriate translators are defined. Then DTrace scripts written for
Solaris/illumos will work on FreeBSD without any changes.
