svn commit: r236944 - head/lib/libusb
Author: hselasky

New Revision: 236944
URL: http://svn.freebsd.org/changeset/base/236944
Log:
LibUSB v1.0 API compiliance and bugfixes.
- Use CLOCK_MONOTONIC instead of CLOCK_REALTIME, because CLOCK_MONOTONIC
does not wrap into negative in near future. This fixes any potential
problems using "pthread_cond_timedwait()".
- Fix a bug where the "libusb_wait_for_event()" function computes an
absolute timeout instead of a relative timeout. USB transfers do
not depend on this timeout value.
- Add dependency towards LibPthread to Makefile, because LibUSB v1.0
needs this library to function correctly.

Lets assume you need to reboot the system at some point and that solves the
problem.

When CLOCK_REALTIME finally goes negative, then pthread_cond_timedwait() will
simply return an error code, due to the negative tv_sec check in there! I see
other clients like sendmail, using even simpler formats like:
tv_nsec = 0;
tv_sec = time(NULL);
If this piece of code stops working at a given data, regardless of uptime,
shouldn't that be fixed now?

Thanks for feedback Bruce.
A final question on the matter:
I tried to use CLOCK_MONOTONIC_FAST when setting up the condition variable.
That did not appear to be support in 9-stable. Is there a list of supported
clocks anywhere?

This check is just to prevent invalid times.

This should be enough for anyone, provided the unspecified point is the boot time. hastd also uses mostly-relative, mostly-monotonic, often 32-bit signed in timeouts internally. E.g., in the function that seems to be causing problems: When CLOCK_REALTIME finally goes negative, then pthread_cond_timedwait() will simply return an error code, due to the negative tv_sec check in there!

Only if you urgently need current systems 32-bit signed time_t, which are rebooted tomorrow with this fix, to not need another reboot for 86 years. Actually `tv_sec = time(NULL);' will overflow on only 26 years on such systems, but time() use not usable together with CLOCK_MONOTONIC. 32-bit signed time_t's are a more general problem. ... A final question on the matter: I tried to use CLOCK_MONOTONIC_FAST when setting up the condition variable. That did not appear to be support in 9-stable. Is there a list of supported clocks anywhere? Don't know, but the list in clock_gettime(2) for -current seems to have them all except CLOCK_THREAD_CPUTIME_ID. That one is also badly named: - verbosely named - has an _ID suffix, unlike all the others Since it is like CLOCK_PROF (the differences are that it is for threads instead of processes, and interrupt times are broken in a different way for it), it should be named more like CLOCK_PROF. Of course the kernel source code has the correct list. Most of these clock ids are only supported by clock_gettime() and clock_getres(). Most of them arent't writeable, so clock_settime() doesn't apply to them. clock_settime(2) is identical with clock_gettime(2), and doesn't say anything about which clocks are read-only -- you have to try to set them to see which, or you can read the POSIX spec to see that CLOCK_MONOTONIC must be read-only. clock_settime(2) also fails to document the (bad) errno for failure with CLOCK_MONOTONIC. It only says "the following error codes _may_ be set", with EINVAL meaning that the clock id was invalid. But in POSIX, EINVAL for just clock_settime() is grossly overloaded; it means any of: - clock_id for unknown clock (this applies to all the functions; the rest are for clock_settime()) - the tp arg (sic; should be the value pointed to be the tp arg) is out of bounds for the specified clock_id - the tp arg (sic) has an out of bounds nanosecond value - the clock_id arg is CLOCK_MONOTONIC. I don't like the explosion of clock ids in FreeBSD, and support for them outside of clock_gettime() and clock_getres() seems to be nonexistent. In man pages for POSIX realtime timers, only the standard CLOCK_REALTIME and CLOCK_MONOTONIC are documented, and the code seems to agree. FreeBSD aliases like CLOCK_REALTIME_PRECISE will work because they are just spelling errors. FreeBSD extensions like CLOCK_REALTIME_FAST won't work for timers, but timers are already

The problem is that fdalloc grows to at most fdp->fd_nfiles * 2, which
still may not be enough to have place for new fd with high number.
This fixed the problem for me, although I'm not sure whether it's ok to
grow the table like this:

svn commit: r236952 - head/sys/dev/mvs
Author: mav
Date: Tue Jun 12 11:08:51 2012
New Revision: 236952
URL: http://svn.freebsd.org/changeset/base/236952
Log:
- Limit r214102 workaround to only x86. On arm it causes more problems
then solves because of cache coherency issues. This fixes periodic error
messages on console and command timeouts.
- Patch SATA PHY configuration for 65nm SoCs to improve SNR same as
Linux does.

Well, to be honest I presonally would prefer explicit check for fd being
less than 0, but my impression was that using cast is the most popular
way and I wanted this check to be consistent across our source tree.
Feel free to change it.
BTW. I really dislike using 'unsigned' with omitted 'int'. u_int is fine.

Re: svn commit: r236955 - head/sys/net
That actually will not effect things. Since the packet is
on the way out. If the csum_data field gets set on the way in
(not out)… so reusing it here I think is safe.

Most changes are obiously yours, so I see no problem if you prefer to commit this yourself. Otherwise I plan to commit it with the following: Re-apply reverted parts of r236935 by pjd with some fixes. If fdalloc decides to grow fdtable it does it once and at most doubles the size. This still may be not enough for sufficiently large fd. Use fd in calculations of new size in order to fix this. Fix description of fd_first_free to note that it returns passed fd if it exceeds fdtable's size. == fd_last_used has very same problem with comment as fd_first_free. This function is static and the only caller always passes 0 as low. Given that, how about the following: http://people.freebsd.org/~mjg/patches/fd_last_used-cleanup.patch Thanks, -- Mateusz Guzik ___ svn-src-head@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/svn-src-head To unsubscribe, send any mail to "svn-src-head-unsubscr...@freebsd.org"

New Revision: 236959

Log:
Add a IP_RECVTOS socket option to receive for received UDP/IPv4
packets a cmsg of type IP_RECVTOS which contains the TOS byte.
Much like IP_RECVTTL does for TTL. This allows to implement a
protocol on top of UDP and implementing ECN.

svn commit: r236962 - in head/contrib/gcc: . config/i386 doc
Author: pfg Date: Tue Jun 12 15:04:18 2012 New Revision: 236962 URL: http://svn.freebsd.org/changeset/base/236962 Log: Add experimental support for amdfam10/barcelona from the GCC 4.3 branch. Initial support for the AMD barcelona chipsets has been available in the gcc43 branch under GPLv2 but was not included when the Core 2 support was brought to the system gcc. AMD and some linux distributions (OpenSUSE) did a backport of the amdfam10 support and made them available. Unfortunately this is still experimental and while it can improve performance, enabling the CPUTYPE may break some C++ ports (like clang). Special care was taken to make sure that the patches predate the GPLv3 switch upstream.

The patch does include some minor fixes for optimizations that GCC developers didn't consider regressions so were never back ported. This was, of course, tested by building world on amd64 (not amdfam10) and shouldn't cause any trouble. I think this ends the series of GPLv2 patches we could bring in.

svn commit: r236965 - in head: etc include lib/libutil share/examples/etc
Author: des
Date: Tue Jun 12 17:02:53 2012
New Revision: 236965
URL: http://svn.freebsd.org/changeset/base/236965
Log:
Finally nuke auth.conf, nine years after it was deprecated. The only
thing it was still used for was to set the "global default" password
hash. Since the stock auth.conf contained nothing but comments, the
global default was actually the first algorithm in crypt(3)'s list,
which happens to be DES; I take the fact that nobody noticed as proof
that it was not used outside of crypt(3).
The only other use in our tree was in the Kerberos support code in
in tinyware's passwd(1). I removed that code in an earlier commit;
it would not have compiled anyway, as it only supported Kerberos IV.
The auth_getval() function is now a stub that always returns NULL,
which has the same effect as a functional auth_getval() with an
empty auth.conf.

svn commit: r236967 - head/lib/libcrypt
Author: des

New Revision: 236967

Log:
Stop using auth_getval() now that it always returns NULL. Instead,
hardcode the default to what it would be if we didn't hardcode it,
i.e. DES if supported and MD5 otherwise.

svn commit: r236976 - head/sbin/fsck_ffs
Author: kib
Date: Tue Jun 12 21:37:27 2012
New Revision: 236976
URL: http://svn.freebsd.org/changeset/base/236976
Log:
For incompleted block allocations or frees, the inode block count usage
must be recalculated. The blk_check pass of suj checker explicitely marks
inodes which owned such blocks as needing block count adjustment. But
ino_adjblks() is only called by cg_trunc pass, which is performed before
blk_check. As result, the block use count for such inodes is left wrong.
This causes full fsck run after journaled run to still find inconsistencies
like 'INCORRECT BLOCK COUNT I=14557 (328 should be 0)' in phase 1.
Fix this issue by running additional adj_blk pass after blk_check, which
updates the field.

This is backwards. Apart from using the worst possible (most verbose)
spelling of `unsigned', it uses a type hack manually optimize away the
test for fd being < 0. The compiler will do this "optimization"
automatically if it is any good (or undo it if it is not), so all the
hack does is obfuscate the test. With the verbose spelling of u_int,
it even takes more space.
Well, to be honest I presonally would prefer explicit check for fd being
less than 0, but my impression was that using cast is the most popular
way and I wanted this check to be consistent across our source tree.
Feel free to change it.
I'm only free to ask you to back out it out.
BTW. I really dislike using 'unsigned' with omitted 'int'. u_int is fine.
I really dislike 'unsigned int'. The int in it is just noise, as in
'long int'.
From K&R 1: p34: "The declarations for the qualifiers look like [...]
unsigned int x; The word int can be omitted in such situations, and
typically is." p45: example that uses plain unsigned. p183: "Unisgned
integers, declared unsigned, ...". p193: [semi-formal grammar]:
"type-specifier: char, short, int, long, unsigned, float, double,
struct-or-union-specifier, typedef-name. [short int, long int,
unsigned int, long float are also acceptable]".
From K&R 2: p36: same as above p34. p49: similar to above p45 (now
missing in index; no longer "implicit int" for the function return
type; excessive use of unsigned fixed). p196: similar to above p183
(now says "...declared using the unsigned keyword). p211: similzr to
above p193 (add void, signed, enum-specifier; remove long float, and
tighten up the description of which combinations are allowed in other
ways).
Other interesting points from K&R:
- according to the grammar, both `unsigned' and 'signed' are full-fledged
types, not qualifiers for integer types. You can even write plain
'signed' meaning 'signed int', but no one does that.
- K&R very rarely uses `unsigned'. This shows that it should rarely be
used. I could only find the above examples in it (these are all that
are in the index for K&R 1), plus 1 more a page later than the p45/49
one (the index is broken in a different way for this -- in K&R 1 the
one on p46 is not indexed, while in K&R 2 the one on p49 is not
indexed).

I agree that this change should backed out for better. It gains nothing
for modern compilers, but makes code reading harder.

svn commit: r237000 - head/sys/dev/ath
Author: adrian
Date: Wed Jun 13 06:57:55 2012
New Revision: 237000
URL: http://svn.freebsd.org/changeset/base/237000
Log:
Implement a separate, smaller pool of ath_buf entries for use by management
traffic.
* Create sc_mgmt_txbuf and sc_mgmt_txdesc, initialise/free them appropriately.
* Create an enum to represent buffer types in the API.
* Extend ath_getbuf() and _ath_getbuf_locked() to take the above enum.
* Right now anything sent via ic_raw_xmit() allocates via ATH_BUFTYPE_MGMT.
This may not be very useful.
* Add ATH_BUF_MGMT flag (ath_buf.bf_flags) which indicates the current buffer
is a mgmt buffer and should go back onto the mgmt free list.
* Extend 'txagg' to include debugging output for both normal and mgmt txbufs.
* When checking/clearing ATH_BUF_BUSY, do it on both TX pools.
Tested:
* STA mode, with heavy UDP injection via iperf. This filled the TX queue
however BARs were still going out successfully.
TODO:
* Initialise the mgmt buffers with ATH_BUF_MGMT and then ensure the right
type is being allocated and freed on the appropriate list. That'd save
a write operation (to bf->bf_flags) on each buffer alloc/free.
* Test on AP mode, ensure that BAR TX and probe responses go out nicely
when the main TX queue is filled (eg with paused traffic to a TID,
awaiting a BAR to complete.)
