[Bug 227880] `kldstat -m` does not work for vmm.ko (while `kldstat -f` does)

Bug ID: 227880
   Summary: `kldstat -m` does not work for vmm.ko (while `kldstat
-f` does)
   Product: Base System
   Version: CURRENT
  Hardware: Any
OS: Any
Status: New
  Keywords: bhyve, needs-qa
  Severity: Affects Only Me
  Priority: ---
 Component: misc
  Assignee: b...@freebsd.org
  Reporter: 0...@freebsd.org

I've got vmm.ko and nmdm.ko loaded.

I can find out if nmdm.ko is loaded by running either `kldstat -n nmdm` or
`kldstat -m nmdm`. When it comes to vmm.ko, however, only `kldstat -n vmm`
works.

In case of `kldstat -m vmm` the following message is printed:

> kldstat: can't find module vmm: No such file or directory

Why is it so?



I'm running 12.0-CURRENT amd64 r333017.

Were there any updates to rtld in head for this alignment stuff, that you
recall?

I forgot to add: brightness works up until the kernel is loader. And the
brightness set by intel-backlight does not survive suspend restore -- it is

  Disable connectat/bindat with AT_FDCWD in capmode

  Previously it was possible to connect a socket (which had the
  CAP_CONNECT right) by calling "connectat(AT_FDCWD, ...)" even in
  capabilties mode.  This combination should be treated the same as a call
  to connect (i.e. forbidden in capabilities mode).  Similarly for bindat.

  Disable connectat/bindat with AT_FDCWD in capabilities mode, fix up the
  documentation and add tests.

[Bug 227552] w, uptime i386 cordeump

[bugzilla-noreply]

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=227552

--- Comment #12 from Dimitry Andric  ---
I bisected, and it turns out r331838 (the merge of clang 6.0.0 and follow-up
fixes) is the first revision with those segfaults:

# ulimit -c 0; for i in /jail/test-r*; do echo "Using jail: $i"; chroot $i
/usr/bin/w; done
Using jail: /jail/test-r331837
12:00PM  up 13:47, 0 users, load averages: 0.23, 0.24, 0.60
USER   TTY  FROM  LOGIN@  IDLE WHAT
Using jail: /jail/test-r331838
Segmentation fault

Since all of the jail in r331837 has been compiled with clang 5.0.1, and all of
r331838 with clang 6.0.0, it is hard to say what is the exact cause.

Interestingly, moving around the libraries used by w seems to influence the
crash, at least for me.  So for example:

$ ldd /usr/bin/w
/usr/bin/w:
libkvm.so.7 => /lib/libkvm.so.7 (0x2807)
libsbuf.so.6 => /lib/libsbuf.so.6 (0x2807d000)
libxo.so.0 => /lib/libxo.so.0 (0x2808)
libutil.so.9 => /lib/libutil.so.9 (0x28099000)
libc.so.7 => /lib/libc.so.7 (0x280ab000)
libelf.so.2 => /lib/libelf.so.2 (0x2820a000)

$ /usr/bin/w
 2:05PM  up 13:53, 2 users, load averages: 2.31, 0.76, 0.66
USER   TTY  FROM  LOGIN@  IDLE WHAT
dimpts/2coleburn.home.andric.com  2:02PM - w

$ mkdir ~/foo

$ cp /lib/libkvm.so.7 /lib/libsbuf.so.6 /lib/libxo.so.0 /lib/libutil.so.9
/lib/libc.so.7 /lib/libelf.so.2 ~/foo

$ LD_LIBRARY_PATH=~/foo /usr/bin/w
Segmentation fault (core dumped)

Meaning, the exact same .so files, but in a different path, crash!  Currently,
I'm thinking that this may be something in the dynamic linker, but I'm still
not sure.

[Bug 227659] [PATCH] src.opts.mk: fix to build WITH_GCC=yes when using an external compiler that supports c++11

[bugzilla-noreply]

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=227659

--- Comment #4 from Kenneth Salerno  ---
(In reply to Mark Millard from comment #2)
Thank you, Mark, for sharing all of your experiences. I have been using an
external comliler since 11.0-RELEASE, and have found 10.x to be impossible to
hack for gcc6 on i386 (I can get it to compile, but it will segfault
somewhere). I wasn't able to use 10.x on my ppc64 QEMU guest in any form so
wasn't attempting external compilers for that version back then.

In general using an external compiler exposes just how fragile the whole system
is because of idiocintricies or bugs of specific compiler versions, but it is
getting easier and easier since 11.0. And I would prefer to not have to resort
to running HEAD, so I retro-patch a currently supported releng version instead.

11.0 was the only version I was able to get a working kernel compiled with gcc5
and gcc, for both i386 and ppc64. Starting with 11.1 I needed to mix a kernel
built with the system compiler, even for i386 where I am using devel/llvm60
that breaks the iwi device driver (won't scan for networks) and for some reason
multimedia/mplayer segfaults when built with any compiler besides the system
compiler.

Verbose boot dmesg.

I'm aware that to control backlight you have to use graphics/intel-backlight
(is there any chance to see this exposed to sysctl in the future without
needing this kludge?) -- and it works if I bind it to some window manager keys.

However, I can not use the brightness keys via window manager nor devd, because
they generate no events at all. I have tried loading different acpi_* kernel
modules, and none of them work.

[Bug 227870] i915 video corruption, hangs

[bugzilla-noreply]

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=227870

Bug ID: 227870
   Summary: i915 video corruption, hangs
   Product: Base System
   Version: 11.1-RELEASE
  Hardware: Any
OS: Any
Status: New
  Severity: Affects Only Me
  Priority: ---
 Component: kern
  Assignee: b...@freebsd.org
  Reporter: mike.d.ft...@gmail.com

When using 2D and 3D accelerated graphics I get corruption like
missing/blinking characters in fonts, broken transparency and torn rectangles
on screen, black with dark blue dots that sometimes move/blink, which sometimes
also show up in textures.

Every half an hour or so of especially intensive use, such as switching
workspaces a lot or running games/flightgear, I see the screen freeze for a
minute, during which everything non-graphics related keeps going -- then most
of the time it recovers, but if one hang happens more hangs are likely to occur
soon, and sometimes they either start happening without a pause, or perf
degrades so bad I have to kill X or reboot the computer.

During that minute I can not do anything at all:
- switching to console does not work;
- if I suspend to reset the video, the whole machine hangs.

So I either have to reboot it -- or just wait a whole minute.

Might be related to https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=194766
but I don't see the same stream of errors, only the "error:
[drm:pid12:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung"
and something else.

Is there a way to at least make this hangcheck run more often, say, every 10
seconds, so I don't have to just sit there?
