Public bug reported:
Binary package hint: wine1.2
Some Windows programs use ptrace pretty unexpectedly. An example is
PokerStars.
This program worked fine under Lucid but under Maverick it fails to
connect to the servers. The reason for this is a new security "feature"
in maverick. The file:
/etc/sysctl.d/10-ptrace.conf
sets
kernel.yama.ptrace_scope = 1
This downside of this is that programs like gdb, strace and valgrind
cannot attach to processes. This might be okay because the users of
these programs will be sophisticated enough to use sysctl if they really
need the functionality.
Users of wine are not necessarily sophisticated. They will just see
Windows programs that worked in Lucid not working in Maverick and think
Maverick sucks.
A work-around for this is to add the capability cap_sys_ptrace to
wineserver using the command:
sudo setcap cap_sys_ptrace=eip /usr/bin/wineserver
I would like to suggest that this command be added to the wine install
script. Even though it opens a security hole, I think it is very
important for functionality. There is no way for the wine project or for
the developers of thousands of Windows applications to fix this.
This should apply to packages wine1.2, wine1.3 and wine-PPA packages.
Also wine will have to depend on the package setcap
