PROBLEM: (MCPM11J3X/MCPM6046A) (Patch ID: OSF425-186) ******** This patch fixes hang conditions experienced with the following networking commands and utilities rsh(1) telnet(1) ftp(1) rdate(8) ping(8) and yppush(8). This problem is usually seen when these utilities are called from scripts. The commands appear to be "hung" but in fact are waiting for an event. A typical stack trace would look as follows: thread_block() mpsleep() event_wait() do_scan() select() syscall() _Xsyscall() Another problem this patch fixes is rsh not catching SIGPIPE. When SIGPIPE was received, rsh would immediately exit without cleaning up. Since rsh is implemented with a parent and its forked child process, the child was not getting cleaned up when the parent couldn't invoke it's normal exit code. PROBLEM: ( QAR 59268 ) (Patch ID: OSF425-405188) ******** This patch corrects a regression problem with the rsh(1) command. PROBLEM: (QAR 61090) (Patch ID: OSF425-405279) ******** This patch corrects a problem with rsh(1) that is most visible with long-distance (slow) links where a packet might get dropped.
