If you forget for any of them, the i386 build seems to contaminate the UML build. Only the executing thread has access to its TLS variable, period, and there is no practical means by which any "central thread" could look at other threads' TLS variables. Marc Chris Clark says: October 22, 2007 at 12:22 pm I am not so familiar with TLS but I am wondering about how it works with thread pool threads? http://ads.osdn.com/?ad_id=3149&alloc_id=8166&op=click Previous Message by Thread: [uml-user] uml fails when host is in skas3 mode - ptrace_mm host2.4.19 - even after patch I searched the archives and found a patch for this.
In my case, FWIW, I was not able to have a function in my thread with a lifetime longer than a generation, so the local variable as the per-thread storage doesn't Some versions of NFS seems not to handle mmap correctly, which UML depends on.

I saw that you can use TLS for antidebug purpose during binary loading : (1) TLS-callback This anti-debug was not so well-known a few years ago. As far as I could tell the patch was for 2.4.21 or .20. from: http://www.securityfocus.com/infocus/1893 (Windows Anti-Debug Reference) It is or will be useful for TCmalloc google portage which is not finish at all but seems pretty cool : http://goog-perftools.sourceforge.net/doc/tcmalloc.html I wait for your Occasionally, we hear from someone who can reach some machines, but not others on the same net, or who can reach some ports on other machines, but not others.
Now, depending on how your hardware and compiler platform implements TLS, there might be a trick around it, if your implemention of TLS works by mapping TLS variables to different virtual My chroot brings "Cannot set up thread-local storage: set_thread_area failed when setting up thread-local storage" and refuse to chroot to /mnt. In this case, I imagine that you cannot use thread local storage to share info "across jobs" because you don't actually know which thread the next job is going to run https://lists.linuxcontainers.org/pipermail/lxc-users/2014-January/006013.html Also see below, where a more specific set of symptoms is described.

If you see File descriptor in bad state when you bring up the device inside UML, you have a header mismatch between the original kernel and the upgraded one. Typically, what happens is that one CPU register is thread-specific, it's set to point to different memory addresses, and all TLS variables are accessed as relative addresses. During upgrade, rpm failed to continue and end up with cannot set up thread-local storage: set_thread_area failed when setting up thread-local storage.

The problem on Windows is performance, the _declspec(thread) seems costly, because each reference to such a var requires an overeahd of getting the TLS info. I hate to spam the group with it unnecessarily. ----- Original Message ----- From: "Jeff Dike" To: "uml" Cc: Sent: Friday, May 21, 2004 1.47 PM Subject: Re: Oracle 10g.

The fix is to move the include/asm link back to include/asm-i386 and to do UML builds someplace else. This is a libc botch, which has since been fixed, and I don't see any way around it besides upgrading.

Well, it turns out that prior to Windows Vista, there are some rather annoying limitations baked into the loader's implicit TLS support.
something like this rpm -e glibc* --root /mnt/sysimage --nodeps then (adjust path and package names as neede of course) rpm -Uvh /mnt/sources/RedHat/RPMS/glibc-x.x.x.i386.rpm --nodeps rpm -Uvh /mnt/sources/RedHat/RPMS/glibc-common-x.x.x.i386.rpm --nodeps rpm -Uvh /mnt/sources/RedHat/RPMS/glibc-devel-x.x.x.i386.rpm --nodeps They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own. The fix is to put less stuff on the command line. The general design is that all TLS accesses go through either a pointer or array that is present on the TEB, which is a system-defined data structure that is already instanced

With this information and a little disassembly work, it is not that hard to understand the implementation behind TLS.
If you do this, the first thing you need to do is clean up the mess you made. Although I'm pleased with the algorithm (and it seems very solid) I do think that Microsoft could have done a better job with this, it really should be a lot less Thank you.
