Here it is for all you Microport shmcreate afficionados :-)
------------
Subject: shmcreate
After spending a long night trying to understand why shmcreate didn't work,
I found that the shmget (create) call was missing the IPC_SHMPHYS flag!
The program could never have worked as coded. Why was the program never
tested before being distributed? I don't know.
Do the following to patch shmcreate so the call is done correctly.
patch shmcreate -b +-831 noerror
Patch should return 0xa. This is the high-order byte of the flag 05000.
Replace that value with the high-order byte of 045000 (74/0x4a) by
installing the following patch:
patch shmcreate -b +-831 noerror 74
Shmcreate should now work.
