/description of the problem/
I am writing a win32 service for Windows NT4sp6a. On the same machine I am running
sshd in a cygwin environment, with ntsec turned on. My win32 service does not use any
of the cygwin services/code. Unfortunately after I log in to an ssh window my service
can no longer run its sub-processes. Also restarting the service breaks the ssh
session, I get errors similar to the following
--------
$ ls
1506 [main] -bash 206 sync_with_child: child 248(0x158) died before initialization
with status code 0x80
2344 [main] -bash 206 sync_with_child: *** child state waiting for longjmp
-bash: fork: Resource temporarily unavailable
-----------
/Implementation details/
My win32 service needs to executes other exes either as the SYSTEM user or as another
local user with less privileges.
To avoid getting the nasty 'user32.dll cannot initialize' errors, I am following the
guidelines from the Microsoft site on how to setup the permissions for the windows
station/desktop: http://support.microsoft.com/default.aspx?scid=KB;EN-US;Q165194. I
have some working code that allows my processes to share the default non-interactive
desktop.
From what I see from the sources, cygwin is also adjusting the permissions on the
station\desktop. The approach taken in spawn.cc is a lot more radical though, the
security descriptor is basically blown away. This seems to break my code.
Has anybody else encountered this problem? Are there plans to move to a more nuanced
approach when adjusting the permissions on the window stations/desktop?
Thanks for any pointers/comments.
