Early use of log() does not end up in kernel msg buffer
Using log(9) when no process is reading the log results in the message going only to the console (contrast with printf(9), which goes to the console and to the kernel message buffer in this case). I believe it is truer to the semantics of logging for messages to *always* go to the message buffer (where they can eventually be collected and in fact put into a logfile). I therefore propose the attached patch, which sends log(9) to the message buffer always, and to the console only if no one has yet opened the log. It may be more complete to log to the console only if the log level is greater than some (user defined) value, but this seems like that might be more than necessary for this case. Thoughts?

11.0-CURRENT: SCTP_MAX_CWND, lib/libc/net/sctp_sys_calls.c -r279859 vs. updating to head snaphot -r280598
Basic context:
# freebsd-version -ku; uname -apKU
11.0-CURRENT
11.0-CURRENT
FreeBSD FBSDG5C0 11.0-CURRENT FreeBSD 11.0-CURRENT #1 r279514M: Sat Mar 21

powerpc powerpc64 1100062 1100062
The problem:
Summary of the details that are listed later. Both of the following exist:
/usr/src/sys/netinet/sctp.h
/usr/include/netinet/sctp.h
The first can be newer than the 2nd during buildworld.
The buildworld compile of /head/lib/libc/net/sctp_sys_calls.c from an updated
/usr/src can/does end up using the second instead of the first, at least for
the powerpc64-xtoolchain-gcc style of buildworld activity that I am trying.
The recent addition of SCTP_MAX_CWND ends up with its definition missing
because of this: during the build /usr/include/netinet/sctp.h ends up being the
file included and the compile fails from the missing additional definition.
Either the #include paths in /head/lib/libc/net/sctp_sys_calls.c or the command
line arguments should force the /usr/src/sys/netinet/sctp.h vintage file to be
found. The 3 netinet/ relevant includes are shown below...
...
#include netinet/in.h
#include arpa/inet.h
#include netinet/sctp_uio.h
#include netinet/sctp.h
More than sctp.h might have such issues since there are 3 netinet/ include
paths in /head/lib/libc/net/sctp_sys_calls.c .
I have not checked for other .c files with similar issues for netinet/...
usage during buildworld.
The problem details:
/head/lib/libc/net/sctp_sys_calls.c -r279859 added:
case SCTP_MAX_CWND:
((struct sctp_assoc_value *)arg)-assoc_id = id;
break;
and head (20150325 r280598) contains it.
But the SCTP_MAX_CWND reference blocks buildworld (for at least
/usr/local/bin/powerpc64-portbld-freebsd11.0-gcc (powerpc64-xtoolchain=gcc)
use):

#define SCTP_MAX_CWND 0x0032
./sys/netinet/sctp.h
And looking at the list of includes in /head/lib/libc/net/sctp_sys_calls.c for
-r279859 shows:
#include sys/cdefs.h
__FBSDID($FreeBSD$);
#include stdio.h

#include sys/syscall.h
#include sys/uio.h
#include netinet/in.h
#include arpa/inet.h
#include netinet/sctp_uio.h
#include netinet/sctp.h
That there was no complaint about sctp.h being missing suggests that a
netinet/sctp.h was found but did not contain a SCTP_MAX_CWND definition: so a
different one than the above find/grep reported.
Using a find to report other sctp.h files shows:
# find / \( -type d -name .svn -prune \) -or \( -type f -name sctp.h -print
\) | more
/usr/src/sys/netinet/sctp.h
/usr/include/netinet/sctp.h
The diff of those shows the problem if the wrong file is found and used:

Hi,
what you thing about this patch?
lp_detaching can be non zero in case of parent interface departure.
So I don't see the reason to call ETHER_BPF_MTAP() in this case.

So I don't see the reason to call ETHER_BPF_MTAP() in this case.
Now I see the reason - to capture all received packets before interface
departure. New is attached.

Suspend sometimes hangs the whole system
Hello, Normally suspend/resume is working fine on my Lenovo Thinkpad T61. But sometimes, when I press the power button to suspend, the whole system hangs and does not suspend. In X11 the mouse cursor goes away and no mouse action is possible. The graphics screen is staying there and it does not switch to console as on a normal suspend. Also manually switching to a console screen is not possible. Even the ssh daemon does not respond when I try to login thhroug ssh from some other pc. Looks like sshd is already sleeping. The only way to get it back to life is a hard reset. How can I investigate this problem further? -- Mit besten Grüßen Jochen Fahrner ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org
