The problem only seems to occur when top shows
RES 0K and a positive SWAP for the failing sh
process before it executes.

When top shows both a positive RES and a positive
SWAP before the execution the sh process does not
die.

For example the following two did not die:

Hi Cassiano,

What's your output of uname -v?

Can you make sure to include a backtrace here from ddb? type "bt" at the prompt
when the panic happens. It may be related but not the same code path.


Cheers,
Franco

Hi Franco,

I don't know exactly which svn version i'm using, because when i run uname -a
it doesn't show me. But anyway i updated my FreeBSD 10.3 on February 6th. Is it
makes sense to you?  How can i revert this commit?

Thanks.

make ifAlias dynamic

FreeBSD allows to assign descriptions to network interfaces by means of
ifconfig(8) utility or kernel API utilized by daemons like net/mpd5.
sysctl net.ifdescr_maxlen limits maximum description length to 1024 bytes by
default, including terminating zero byte.

bsnmpd shows these descriptions with ifAlias OIDs in the ifXTable (MIB-II) but
has compiled-in limit MIBIF_ALIAS_SIZE equal to 65 bytes. If an interface has
longer description (say, 70 bytes), bsnmpd complains:

SIOCGIFDESCR (ng7): too long (70)

And no description is returned to interface's ifAlias OID.
Nevertheless, bsnmpd allocates a buffer of MIBIF_ALIAS_SIZE bytes to every
network interface, is it used or not.

Attached patch solves these problems and little more:

- bsnmpd's network interface buffers for description/ifAlias now have dynamic
size and allocate exact number of bytes; no extra memory allocated for
interfaces having no description;

- sysctl net.ifdescr_maxlen is used as limit instead of compiled-in
MIBIF_ALIAS_SIZE; changes to this sysctl updated without restart of bsnmpd;

- no more strlen() calls on every SNMP request for an ifAlias: we calculate
actual size of buffer once, store it and use when needed;

- corresponding data moved from struct mibif_private to struct mibif just as
suggested by a comment: /* this should be made public */.

[Bug 217761] FreeBSD/powerpc64 head r313561's /boot/loader cannot boot the kernel from NFS

2017-03-13 Thread bugzilla-noreply

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=217761

Bug ID: 217761
   Summary: FreeBSD/powerpc64 head r313561's /boot/loader cannot
boot the kernel from NFS
   Product: Base System
   Version: CURRENT
  Hardware: powerpc
OS: Any
Status: New
  Severity: Affects Only Me
  Priority: ---
 Component: bin
  Assignee: freebsd-bugs@FreeBSD.org
  Reporter: hiroo.ono+free...@gmail.com

I installed FreeBSD/powerpc64 head r313561 (snapshot of 20170210) and there is
something wrong with its bootloader.

I tried to net boot the installer. The configuration of isc-dhcp is:

host powerpc {
  hardware ethernet xxx:xx:xx:xx:xx:xx;
  fixed address 192.168.0.15;
  next-server 192.168.0.10;
  filename "loader";
  option root-path "192.168.0.10:/exports/FreeBSD/ppc64/12c-20170210";
}

tftp configuration in inetd.conf is:

tftp dgram udp wait root /usr/local/libexec/in.tftpd in.tftpd -s
/exports/FreeBSD/ppc64/12c-20170210/boot

and 192.168.0.10:/exports/FreeBSD/ppc64/12c-20170210 is NFS mountable with full
system
copied from disc1.iso.

I tried to boot from openfirmware console

> boot eboot:,loader

the file loader is retrieved via tftp and executed, but it says it cannot find
the file 'kernel'.

I replaced /boot/loader with the loader of 11.0-RELEASE. It successfully booted
/boot/kernel/kernel,
and I managed to install.

addresses and addresses are unsorted, for example:

# open standard SNMP ports

--- Comment #11 from Cassiano Peixoto  ---
Guys,

I'm having the same issue here on FreeBSD 10.3-STABLE. I'm using Atom C2758 as
well. It has began after 10.3 update. It's very serious issue because many
production servers are crashing. Can someone take a look please?

Thanks.

[Bug 217751] Xenstore: there is a deadlock when suspending user-space processes

2017-03-13 Thread bugzilla-noreply

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=217751

Bug ID: 217751
   Summary: Xenstore: there is a deadlock when suspending
user-space processes
   Product: Base System
   Version: 10.3-RELEASE
  Hardware: amd64
OS: Any
Status: New
  Severity: Affects Some People
  Priority: ---
 Component: kern
  Assignee: freebsd-bugs@FreeBSD.org
  Reporter: ouyangzhao...@huawei.com

If there is a user process which maybe often reads and writes xenstore, the
application has been suspended after stop_all_proc is called. It held
xs.request_mutex lock but in the following functions xs_write and xs_suspend
will not get the lock. So the VM will hang.

When running on Xen, it's possible that a suspend request to the hypervisor
fails(return from HYPERVISOR_suspend different than 0), such as when VM dirty
pages are faster than the rate of copying. This means that the suspend hasn't
succeed, and the resume procedure needs to properly handle this case.

[Bug 217736] addr2line incorrectly resolves filename/lineno/function

2017-03-13 Thread bugzilla-noreply

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=217736

Bug ID: 217736
   Summary: addr2line incorrectly resolves
filename/lineno/function
   Product: Base System
   Version: 11.0-RELEASE
  Hardware: Any
OS: Any
Status: New
  Severity: Affects Some People
  Priority: ---
 Component: misc
  Assignee: freebsd-bugs@FreeBSD.org
  Reporter: ma...@slonopotamus.org

Way to reproduce:

1. fetch http://slonopotamus.org/libUE4Editor-Core.so (warning, 50MB)
2. addr2line -f -e libUE4Editor-Core.so +0x2c09b2

Expected output,given by addr2line from GNU binutils and gdb (and I in fact
know that this is what I want to get):

  _Z20PlatformCrashHandleriP9siginfo_tPv
 
/home/marat/production/ue4/Engine/Source/Runtime/Core/Private/Linux/LinuxPlatformCrashContext.cpp:595

Actual output:

  ??
  Runtime/Core/Public/Delegates/DelegateInstancesImpl.h:869

I have already reported this to elftoolchain project, though am not sure
whether I should (not) also report this to FreeBSD.

For the reference, elftoolchain bug reports (note that it crashes with -f,
unlike FreeBSD addr2line):
