Re: xorriso in ghostbsd-build

Hi, ASX wrote: I also hope that the "per driver lock" (sound very weird just by its name, because implicitly exclude parallel use of the same driver) has been removed since then. Nothing happened since the introduction of the global mutex of driver "sr" in 2010. The big injustice is that only SCSI p...

Re: xorriso in ghostbsd-build

Hi, i set up that system 7 years ago. AMD with 4 x 2.4 GHz, kvm-ready. If i remember right, the master boot loader is GRUB Legacy, installed and managed by the old Debian system. It chainloads partition boot loaders. Main question is whether i should upgrade only FreeBSD or also the GNU/Linux and pu...

Hi, ericbsd wrote: I am looking forward to taking ownership of maintaining xorriso ports since GhostBSD and some iXsystems depend on it. Be aware that the bug fix belongs into the devel/libisofs port. Don't hesitate to ask for advice about upstream or for adaptions for BSD systems. I test each relea...

Re: xorriso in ghostbsd-build

Hi, When we added a marker for the end of the page list, that become the 20th element. Probably as consequence of the bug. In http://forums.ghostbsd.org/viewtopic.php?f=98&t=711&start=20#p4858 i count 19 lines of "3L". That many complete loop passes happened. Then at some point of the 20th pass it c...

Re: xorriso in ghostbsd-build

Hi, to make the license mess complete, the dynamically linked xorriso updates its license to GPLv3+ when it gets linked with the GPLv3+ licensed version of libreadline. xorriso 1.3.2 : RockRidge filesystem manipulator, libburnia project. ...

Re: xorriso in ghostbsd-build

Hi, thanks for your fine cooperation on this issue, that afflicted us for long time! Thanks to you for hunting down this nasty crack in the code. I am the one to blame here, not Vladimir Serbinenko. Vladimir submitted a table as array of C constants which stemmed from a copyrighted example program. ...

I meanwhile assume that -O2 embedded the code of the function into the code of its only caller. So the printf up there could influence the behavior of the function. Did you ...

It is suspicious that the last code page block in class_page_data[] does not end by 0x0, as do all others. Also the list of 16-bit nu...
