Abstract

OSP-INCORROUT PASE FOR i SHMCTL DOES NOT WORK FOR SHMID 203

Error Description

The PASE for i shmctl function ignores the "command" argument  
and handles any request to shmid 203 as a SHM_GETLBA command.  
In addition, any SHM_GETLBA request for a shmid other than 203  
returns incorrect results.                                      
The shmctl implementation in SLIC tests the shmid argument      
instead of the cmd argument when checking for command          
SHM_GETLBA (203).                                              
Any shmctl() request for shmid 203 attempts to perform the      
SHM_GETLBA operation, which either returns EFAULT (typically    
when the third shmctl argument is zero) or sets field shm_lba  
in the result buffer.                                          
The problem exists in R610 and later.
