svn commit: r228525 - head/usr.bin/make
Author: fjoe
Date: Thu Dec 15 06:25:19 2011
New Revision: 228525
URL: http://svn.freebsd.org/changeset/base/228525
Log:
Revert r228521: sometimes job output is lost
(see tools/regression/usr.bin/make/execution/joberr test).
openpty(fd + 0, fd + 1,...) version does not have this problem but
it sometimes enters an infinite sleep in "ttywait" state in tty_drain()
when make(1) closes slave pty.

Date: Thu Dec 15 02:26:53 2011
New Revision: 228520
URL: http://svn.freebsd.org/changeset/base/228520
Log:
Honor NFSv3 commit call (RFC 1813, Section 3.3.21) where when count is 0,
the full length from offset is being flushed. Note that for now VOP_FSYNC
does not support offset and length parameters so we still do the same full
VOP_FSYNC. This issue was reported at FreeNAS support site as FreeNAS
ticket #1096.

svn commit: r228518 - head/sys/mips/atheros
Author: adrian
Date: Thu Dec 15 01:03:49 2011
New Revision: 228518
URL: http://svn.freebsd.org/changeset/base/228518
Log:
Re-jiggle the GPIO code a little to remove the hard-coded AR71xx GPIO
config and function mask setup.
* "gpiomask" now specifies which GPIO pins to enable, for devices to bind to.
* "function_set" allows bits in the function register to be set at GPIO setup.
* "function_clear" allows bits in the function register to be cleared at
GPIO setup.
The function_set/function_clear bits allow for individual GPIO pins to either
drive a GPIO line or an alternate function - eg USB, JTAG, etc. This allows
for things like CS1/CS2 be enabled for those boards w/ >1 SPI device
connected,
or disabling JTAG for the AR7240 (which is apparently needed ..)
I've verified this on the AR71xx.

svn commit: r228517 - in head/sys/dev/ath/ath_hal: ar5416 ar9002
Author: adrian
Date: Thu Dec 15 00:59:11 2011
New Revision: 228517
URL: http://svn.freebsd.org/changeset/base/228517
Log:
Add the 11n chipset RF frontends to the linker set, even though they're not
attached this way.
The AR5212 based NICs have a variety of RF frontends, so there's a linker set
which the AR5212 attach routine calls. The same framework is used for the
AR5416 and later but as there's a fixed RF frontend for each 11n NIC, it
is just directly attached.
However in the case of compiling a cut down HAL (eg _just_ AR9130 WMAC
support),
the linker set ends up being empty and this causes the compile to fail.
So this is just a workaround for that - it means those users who wish an 11n
only HAL can compile the 11n chipsets and RF frontend they need, and just
"ath_ar5212" for the AR5212/AR5416 common code, and it'll just work.

svn commit: r228514 - head/sys/net80211
Author: adrian
Date: Thu Dec 15 00:52:30 2011
New Revision: 228514
URL: http://svn.freebsd.org/changeset/base/228514
Log:
Modify the ACL code slightly to support a few nifty things:
* Call it before sending probe responses, so the ACL code has the
chance to reject sending them.
* Pass the whole frame to the ACL code now, rather than just the
destination MAC - that way the ACL module can look at the frame
contents to determine what the response should be.
This is part of some uncommitted work to support band steering.

svn commit: r228510 - head/sys/kern
Author: jilles
Date: Wed Dec 14 22:26:39 2011
New Revision: 228510
URL: http://svn.freebsd.org/changeset/base/228510
Log:
Fix select/poll/kqueue for write on reverse direction before first write.
The reverse direction of a pipe is lazily allocated on the first write in
that direction (because pipes are usually used in one direction only). A
special case is needed to ensure the pipe appears writable before the first
write because there are 0 bytes of pending data in 0 bytes of buffer space
at that point, leaving 0 bytes of data that can be written with the normal
code.
Note that the first write returns [ENOMEM] if kern.ipc.maxpipekva is
exceeded and does not block or return [EAGAIN], so selecting true for write
is correct even in that case.

Log:
Merge ext2_readwrite.c into ext2_vnops.c as done in UFS in r101729.
This removes the obfuscations mentioned in ext2_readwrite and
places the clustering funtion in a location similar to other
UFS-based implementations.
No performance or functional changeses are expected from
this move.

svn commit: r228503 - in head/libexec/rtld-elf: . amd64 i386
Author: kib
Date: Wed Dec 14 16:47:53 2011
New Revision: 228503
URL: http://svn.freebsd.org/changeset/base/228503
Log:
_rtld_bind() read-locks the bind lock, and possible plt resolution
from the dispatcher would also acquire bind lock in read mode, which
is the supported operation. plt is explicitely designed to allow safe
multithreaded updates, so the shared lock do not cause problems.
The error in r228435 is that it allows read lock acquisition after the
write lock for the bind block. If we dlopened the shared object that
contains IRELATIVE or jump slot which target is STT_GNU_IFUNC, then
possible recursive plt resolve from the dispatcher would cause it.
Postpone the resolution for irelative/ifunc right before initializers
are called, and drop bind lock around calls to dispatcher. Use
initlist to iterate over the objects instead of the ->next, due to
drop of the bind lock in iteration.
For i386/reloc.c:reloc_iresolve(), fix calculation of the dispatch
function address for dso, by taking into account possible non-zero
relocbase.

The other places give a definition of __aligned() that can almost be used here. There is a bogus one for lint and a duplicate one for __INTEL_COMPILER. But there is none for !__GNUC_PREREQ__(2, 7) && !__INTEL_COMPILER. That is, all cases where the compiler is either gcc-before-2.6, or non-gcc other than lint and icc, are already broken. #define _Alignof(e) __alignof__(e) This one mainly has a style bug. __alignof__ would be be spelled __alignof if this were FreeBSD code. gcc has accepted all of alignof(), __alignof() and __alignof__() for a long time. I checked this for some gccs back to gcc-2.95.4. It might even work for gcc-1. FreeBSD uses the extra trailing underscores for __attribute__(()) and individual attributes because unlike for __alignof() and __typeof(), gcc used to require them and changing this now would give style bugs. gcc-4.2.1 accepts the __aligned__ attribute, but gcc-3.3.3 doesn't. I don't know when __attribute(()) started working. I checked it for some gccs back to gcc-2.95.4, and all accepted it. #define _Noreturn __attribute__((__noreturn__)) Elsewhere in this file, the __noreturn__ attribute is handled like the __aligned__ attribute, but more carefully, with many style bugs but no bugs as far as I can see: - For lint, the macro that uses it (__dead2) is bogusly defined as nothing. I thought that lint bogusly defines __GNUC__, but can't find this now. Lint should not define __GNUC__ since it only supports a tiny subsets of gcc features like __attribute__(), even with -g. If lint defined __GNUC__, then the extra ifdef for it would be be justified for some of the macros including __dead2/_Noreturn, since __dead2 has no semantic effect so it is safe to make it null for compilers that don't support it. If lint doesn't define __GNUC__ then for __dead2 and now hopefully for _Noreturn, an extra ifdef is not needed since lint is given a null definition in the section for nondescript non-gcc compilers. - For non-gcc, or gcc < 2.5, and not icc, __dead2 is defined as nothing under the condition: #if !__GNUC_PREREQ__(2, 5) && !defined(__INTEL_COMPILER) - For gcc-2.5 and gcc-2.6, and icc, __attribute__((__noreturn__)) is used to define __dead2 under the condition: #if __GNUC__ == 2 && __GNUC_MINOR__ >= 5 && __GNUC_MINOR__ < 7 && \ !defined(__INTEL_COMPILER) Note the style bug in this condition (it doesn't use GNUC_PREREQ()). - For gcc >= 2.7, the definition of __dead2 is duplicated under the condition: #if __GNUC_PREREQ(2, 7) - For icc, the definition of __dead2 is duplicated yet again, under the condition: #if defined(__INTEL_COMPILER) Note the style bug in this (defined() when ifdef would do). There are 2 other definitions under the gcc-2.5, gcc-2.6, or icc ifdef. Only the one for __unused belongs there, since its attribute is new in gcc-2.7. The others should be defin

.Sh DESCRIPTION
The kernel uses a radix tree structure to manage routes for the
networking subsystem.
+If compiled with
+.Cd options RADIX_MPATH
+kernel may maintain several independent forwarding information databases
(FIBs).
The
.Fn rtalloc
-family of routines is used by protocols to query this structure for a
+family of routines is used by protocols to query these structures for a
route corresponding to a particular end-node address, and to cause
certain protocol\- and interface-specific actions to take place.
-.\" XXX - -mdoc should contain a standard request for getting em and
-.\" en dashes.
.Pp
-.Dv RTF_PRCLONING
-flag is obsolete and thus ignored by facility.
-If the
-.Dv RTF_XRESOLVE
-flag is set, then the
-.Dv RTM_RESOLVE
-message is sent instead on the
-.Xr route 4
-socket interface, requesting that an external program resolve the
-address in question and modify the route appropriately.
-.Pp
-The default interface is
-.Fn rtalloc .
-Its only argument is
+The
+.Fn rtalloc1_fib
+function is the most general form of
+.Fn rtalloc ,
+and all of the other forms are implemented as calls to it.
+It takes a
+.Fa "struct sockaddr *"
+directly as the
+.Fa dst
+argument.
+The second argument,
+.Fa report ,
+controls whether the routing sockets are notified when a lookup fails.
+The third argument,
+.Fa flags ,
+is a combination of
+the following values:
+.Bl -item -offset indent
+.It
+.Dv RTF_RNH_LOCKED
+indicates that the radix tree lock is already held
+.El
+.Pp
+The last argument
+.Fa fibnum
+specifies number of forwarding information database (FIB) on which
+the lookup should be performed.
+In case of success the
+.Fn rtalloc1_fib
+function returns a pointer to a locked
+.Vt "struct rtentry"
+with an additional reference.
+.Pp
+The
+.Fn rtalloc_fib
+is the most simple variant.
+Its main argument is
.Fa ro ,
a pointer to a
-.Dq Li "struct route" ,
+.Fa "struct route" ,
which is defined as follows:
.Bd -literal -offset indent
struct route {
- struct sockaddr ro_dst;
struct rtentry *ro_rt;
+ struct llentry *ro_lle;
+ struct sockaddr ro_dst;
};
.Ed
.Pp
Thus, this function can only be used for address families which are
smaller than the default
-.Dq Li "struct sockaddr" .
+.Ft "struct sockaddr" .
Before calling
-.Fn rtalloc
+.Fn rtalloc_fib
for the first time, callers should ensure that unused bits of the
structure are set to zero.
+The second argument
+.Fa fibnum
+is FIB number.
+In case of success of the
+.Fn rtalloc_fib
+the
+.Fa ro_rt
+points to a valid and unlocked
+.Xr rtentry 9 ,
+which has an additional reference put on it, freeing which is
+responsibility of the caller.
On subsequent calls,
-.Fn rtalloc
+.Fn rtalloc_fib
returns without performing a lookup if
.Fa ro->ro_rt
is non-null and the
.Dv RTF_UP
-flag is set in the route's
-.Li rt_flags
+flag is set in the rtentry's
+.Fa rt_flags
field.
.Pp
The
-.Fn rtalloc_ign
-interface can be used when the caller does not want to receive
-the returned
-.Fa rtentry
-locked.
-The
-.Fa ro
-argument is the same as
-.Fn rtalloc ,
-but there is additionally a
+.Fn rtalloc_ign_fib
+function is the same as the
+.Fn rtalloc_fib ,

I see, thanks for the explanation. Could you elaborate a bit more
about how you would implement the function pointer idea? I'm also
curious in the !FFCLOCK case just how much overhead having the
2-layer nested if/else adds. I'm not an very optimisation savvy
person, but I'm wondering if it's actually worth micro-optimising
this code.
My initial thoughts about your function pointer idea lead to
adding a function pointer in the bpf_d and setting it to the
appropriate function to get the timestamp from at bpf_d creation
or ioctl time. Whilst I like this idea, I can't see how it would
work given that the various functions involved in time/ffcounter
stamp generation all have different signatures.
We could have multiple variants of bpf_gettime() which each call
the appropriate underlying functions to generate the appropriate
stamp. Would add quite a lot of code but would reduce the
overhead of calling bpf_gettime() to an indirect function call +
the underlying stamp generation function call. This also solves
the problem of multiple function signatures.

svn commit: r228495 - head/sys/sys
Author: ed
Date: Wed Dec 14 09:09:37 2011
New Revision: 228495
URL: http://svn.freebsd.org/changeset/base/228495
Log:
Slightly alter the C1X definitions in in cdefs.h:
- Add _Alignas(). Unfortunately this macro is only partially functional.
The C1X standard will allow both an integer and a type name to be
passed to this macro, while this macro only allows an integer. To be
portable, one must use _Alignas(_Alignof(double)) to use type names.
- Don't do _Static_assert() when __COUNTER__ is not supported. We'd
better keep this implementation robust and allow it to be used in
header files, without mysteriously breaking older compilers.
