Zoom....
Hi, folks,
Updated CentOS 7 the other day. Updated zoom last night. Ancient (15
yr old) USB camera, Logitech QuickCam Express.
If I run LD_PRELOAD=/usr/lib64/libv4l/v4l2convert.so cheese, I get
video. Zoom, with or without the LD_PRELOAD - no video. I've tried
stracing zoom, and created a file /etc/ld.so.preload, with the contents
of /usr/lib64/libv4l/v4l2convert.so, and in strace, I see it loading it,
but still no video.
Anyone...

Preloading shared library with libVirt
Hi,
I am trying to preload two shared libraries while running Qemu using
libvirt. To preload the shared libraries I have added an environment
variable in the $domain.xml file with the following command:
```
virt-xml generic --edit --confirm --qemu-commandline
'env=LD_PRELOAD=/home/probir/Downloads/kpv_temp/temp/kvmTest/build_kvm/libperform.so:/home/probir/Downloads/kpv_temp/temp/kvmTest/dependencies/libmonitor/installDir/lib/libmonitor.so'
```
However, while running the domain, I get the following message of failure
to preload the shared files in the log.

IntrusiveRefCntPtr vs std::shared_ptr
...prepending a 32 bit object size, just for
realloc(), grrrrrr kill it with fire), and a free() that is an empty
function. There's a calloc() that calls the above malloc() and then
memset(). And a realloc() that is a no-op if the size is smaller, or does
malloc(), memcpy() if bigger.
Then I used LD_PRELOAD to replace the standard malloc library with mine.
Result: ~10% faster execution than llc without LD_PRELOAD, and ~180 MB of
the array used (120 MB on the 32 bit ARM).
Then I built BDW GC as a malloc replacement (with free() as a no-op) and
used LD_PRELOAD with it.

Playing Games with Wine while listening to music
I have this problem: When playing a PC game via wine while listening to music with let's say Amarok, there's no sound in the PC game anymore. It's like the sound channel is occupied by the music player so wine cannot playback any soundfiles.
Sounds are working if I play a Linux game like Nexuiz while running some music via a music player (ok, completely different, I know, but

[Bug 2394] New: Provide a global configuration option to disable ControlPersist
...Reporter: jjelen at redhat.com
Created attachment 2616
--> https://bugzilla.mindrot.org/attachment.cgi?id=2616&action=edit
proposed patch
+++ This bug was cloned from Red Hat Bugzilla ? Bug 1218351 +++
The new ControlPersist feature undesireably closes fds that are loaded
by an adhoc LD_PRELOAD application.
Customer would like to be able to remove the ControlPersist feature set
by providing a global configuration option. This will allow ssh to act
as it did before and not interfere with customer adhoc LD_PRELOAD app.
e.g.
if( options.controlpersist != 0 ){ closefrom(STDERR_FILENO+1) }...

ssh closing file descriptors for ControlPersist
Hi all,
we were discussing internally how to make openssh leave open file
descriptors that were open before main using LD_PRELOAD. Lately I filled
upstream bugzilla [1] with proposed solution, that could be acceptable
by upstream, but I'm also posting on this list to get more attention,
other points of view or ideas for this case.
I understand well, that closing FDs is important for backgrounded [mux]

error on startup
...t and unset
environment variables for the target process.
It is possible to provide several variables by separating them
by commas in getsubopt(3) style. Additionally it is possible to
provide the -E and -U options multiple times.
The following lines are equivalent:
-E var1=val2 -E var2=val2 -U LD_PRELOAD -U LD_DEBUG
-E var1=val2,var2=val2 -U LD_PRELOAD,LD_DEBUG
QEMU_SET_ENV=var1=val2,var2=val2 QEMU_UNSET_ENV=LD_PRELOAD,LD_DEBUG
Note that if you provide several changes to a single variable
the last change will stay in effect.

[LLVMdev] Hidden-visibility aliases to default-visibility globals
...e best way to fix this. The
GlobalValue::mayBeOverridden() function controls whether LLVM resolves
aliases, and hacking this function to return true if a global is hidden
gets around this particular problem, but converts the function into a
misnomer (a hidden alias may _not_ be overridden, e.g. by LD_PRELOAD,
although I'm pretty sure mayBeOverridden is not intended to care about
LD_PRELOAD) and results in a lot of deoptimisation. I'm thinking
of introducing a new function GlobalAlias::mayBeResolved() which
returns true if mayBeOverridden() returns false and the visibility
of the alias is the s...

[RFC] aptitude & BTRFS slowness
...of aptitude on a BTRFS filesystem.
I don''t think that BTRFS is a slow filesystem, but it seems that some aptitude
(or dpkg) patterns are capable to highlight the btrfs slowness in some corner
case.
In order to alleviate this problem, I wrote a small script which calls
aptitude with the LD_PRELOAD libeatmyadata library. And now I want to share
this idea (which is not my own, you can see several suggestion about that in
the net) in order to collect suggestions and/or critics.
For who which don''t know what is libeatmydata, the package info says:
