Description Flags
patch to set perms of semaphores in mm none

Description Jonathan Kamens 2002-07-15 19:56:56 UTC 
When mm is told to change the ownership or modes of a shared memory object, it
doesn't properly update the ownership or mode of semaphores (assuming that it is
compiled with semaphores enabled).  I'll attach a patch.

patch to set perms of semaphores in mm
Comment 2 Nalin Dahyabhai 2002-07-24 19:05:48 UTC 
Fixing for 1.1.3-8 and later.
Comment 3 Jonathan Kamens 2002-07-26 14:15:10 UTC 
The author of mm pointed out a problem in my patch.  When I wrote "i <=
sizeof(sems)/sizeof(*sems)", the "<=" should have been "<".  Please fix this if
you retained the bug when integrating my patch into your package.

Also, he said that my fix will be in mm 1.2.0, although I don't know if/when
that'll be released.
