Patch Name: PHCO_27133 Patch Description: s700_800 10.20 lpspool subsystem cumulative patch Creation Date: 02/08/05 Post Date: 02/08/08 Hardware Platforms - OS Releases: s700: 10.20 s800: 10.20 Products: N/A Filesets: PrinterMgmt.LP-SPOOL Automatic Reboot?: No Status: General Release Critical: No Path Name: /hp-ux_patches/s700_800/10.X/PHCO_27133 Symptoms: PHCO_27133: 1. lpsched(1m) was not killing its children when lpshut(1m) was run. 2. lpadmin(1m) dumps core in certain conditions. 3. rlpdaemon(1m) is not behaving properly in certain conditions. 4. lp spooler commands dumps core in certain conditions. PHCO_25109: 1. rlpdaemon(1M) is mis-behaving in certain conditions. 2. rlpdaemon(1M) is not functioning as expected in certain cases. PHCO_24699: 1. rlpdaemon is not functioning as expected in certain cases. 2. Multiple lpscheds can be running simultaneously. 3. lp was sending a corrupted mail message. PHCO_22364: 1. If a printing request is cancelled, the other requests in the printer queue are not getting printed until another request is given to the queue. 2. rlp may hang indefinitely when the remote machine goes down and comes up. 3. The remote request with the user name having one or more spaces, is not getting processed. 4. rlpdaemon, lpstat, lp, cancel, disable, enable, rlpstat and rcancel have memory overflow. 5. When a request is transferred from a non BSD (Berkeley Software Distribution) printer to a remote BSD printer, the remote BSD printer gets disabled without printing the job. In case of BSD to remote non-BSD printer, the request is printed but the residual datafile remains on the system. 6. If rlpdaemon writes the messages (for eg: when lp or lpalt are invoked with -w option for remote printers) without stripping the control characters, some of these control characters can make the user's terminal behave abnormally. Some times the user terminal may be closed. 7. Data does not get printed when a remote request is given with a very long title. 8. When large number of requests (around 120-130) are given, sometimes the spooler stops printing requests in between. 9. lpadmin does not configure a remote printer properly if the length of printer name is exactly 14 characters. PHCO_18779: lpstat gives "Status received is corrupt message" with remote printers on Sun. PHCO_17713: 1. cancel(1) does not work with printer queue length==14 chars 2. datafiles not removed after an lpalt from PHCO_13133 onwards. 3. cancel(1) returns exit value of 0 even if failed w/ permission denied. 4. rlpdaemon lockfiles remain with FQDNs after patch PHCO_12894. PHCO_16724: kill -9 on interface script and other lp processes causes a corruption in the pstatus file entries. PHCO_16294: lpsched deadlocks on remote printers when remote system is down. PHCO_16106: lp(1) does not link data files to the SPOOL directory as the man page states. PHCO_14431: 1. LP spooler needs to support P405 and HP5000D640 model printers. 2. The value of LANG env variable is improperly passed to the model script PHCO_14029: 1. If you submit more than 52 files lp does not remove those above 52. 2. lpsched -v writes strange strings in log file if LANG is set. 3. lpsched -v intermittently stops by SIGSEGV in catgets if LANG is set. PHCO_13133: 1)incomplete lpstat output when -a/-p option used with printer name and class 2)After PHCO_11462, moving request with lpalt leaves data file in req dir PHCO_12894: 1. Jobs submitted to a LP remote printer that points to a "disabled" remote HPDPS printer are discarded. 2. When more than one jobs, whose job sequence numbers are the same, are simultaneously submitted from the same host to the same remote printer through RFC1179 protocol, rlpdaemon(1M) fails to spool the jobs on the remote system due to data/control file name collision. 3. All jobs from any HPDPS printers are spooled under the /usr/spool/lp/request/PDRequest by rlpdaemon(1M). This single PDRequest directory increases the chance of file name collision due to simultaneous job submission. PHCO_11462: 1. Cancelling a lp job with empty control file clears the whole queue. 2. Printer gets disabled on cancelling a printing job. PHCO_10891: 1. "lpstat -i -o" doesn't inhibit the reporting of the remote status if a HPDPS printer name is specified. This problem happens only when the HPDPS patch, PHCO_10608, is installed on the system. Because of this, CDE print manager doesn't work correctly for HPDPS printers. PHCO_10749: 1. LP-spool hang or qstatus corrupt when /var full log says:Bogus request 2. Parent lpsched hangs when lpalt is used to move a request. 3. Model scripts does not handle SIGTERM any more. 4. lpsched introduced 5 sec delay between prints at 10.20 PHCO_8488: 1. lpsched hangs under FIFO full condition 2. Printers go idle even when requests are present in the queue 3. Jobs not printed when remote host(IBM) immediately saps connection. 4. If a BSD system spooler sends a '\001' to rlp(1) after the control file has been sent, rlp(1) simply ignores the '\001' and removes the entry. 5. lp, cancel, and lpstat hang when forwarding jobs or requests to HPDPS. 6. Implicit requirement that a rlpdeamon client's remote printer name must be the same as its local pseudo name. Defect Description: PHCO_27133: 1. For every print request, lpsched forks a child which handles that request. lpsched was not killing its child processes when lpshut was run, printing jobs were not stopped. Resolution: The problem was in handling the signals. Signal handlers for the signal SIGTERM were not properly set. The changes are made such that signal handlers are set at proper places. 2. lpadmin dumps core and does not display proper messages. Resolution: Changes are done in the code such that core dump does not occur and messages are printed properly. 3. rlpdaemon (1m) is not behaving properly in certain conditions. Resolution: Code is modified such that rlpdaemon (1m) behaves properly. 4. lp spooler commands dumps core in certain conditions and does not display proper messages. Resolution: Changes are done in the code such that core dump does not occur and messages are printed properly. PHCO_25109: 1. rlpdaemon(1M) is mis-behaving in certain conditions. Resolution: Code is modified so that rlpdaemon(1M) would behave correctly. 2. rlpdaemon(1M) is not functioning as expected in certain cases because of improper file handling. Resolution: Code is modified to handle the files properly. PHCO_24699: 1. rlpdaemon is not functioning as expected in certain cases because of improper memory handling. Resolution: A new condition is added in the code to handle the problem. 2. In lpsched startup, there is a large window for a race condition that allows multiple lpscheds to start. Resolution: The fix is that ~lp/SCHEDLOCK file is opened and it is locking the file descriptor. If one lpsched is already running,the second/any next lpsched will not run as there is already lock being aquired by another process (which is already running) 3. A newline character was missing in lpsched mail text , due to which the mail mesage was getting corrupted when read through /usr/bin/mail. Resolution: The newline character '/n' has been added in the end of mail message for lp -m , so that messagees don't get corrupted with lp -m. PHCO_22364: 1. When a printing request is cancelled, there is no instruction for lpsched to continue processing other existing requests in the queue. Resolution: When the printing process is killed, an instruction is given to the scheduler to continue with the other requests in the spooler. 2. rlp sends a request to rlpdaemon and waits for the acknowledgement in read call on the socket. read() is waiting indefinitely even when the remote machine goes down without closing the socket. Resolution: SO_KEEPALIVE option is set for the socket so that if there is no response for 2 hours, the read() call returns with an error instead of waiting indefinitely. 3. The remote request with the username having spaces is not getting processed because of the incorrect parsing of arguments in rlpdaemon. Resolution: It is made sure that the parsing of arguments is done correctly and the request is processed. 4. Memory fault in the commands is because of the incorrect handling of buffer for error message. Resolution: The buffer size is increased for the error message. If the argument is longer than the allocated buffer size, it is truncated before printing the error message. 5. When the requests are transfered from non-BSD printer to remote BSD printer, datafilename has been renamed incorrectly and the request remains unprocessed. When the request is transfered from BSD printer to remote non-BSD printer, the request gets processed but the datafile, which is named incorrectly, remains in the request directory. Resolution: The fix is to add more conditions so that the datafile is renamed appropriately while the request is being transfered from BSD to non-BSD printer and vise-versa. 6. rlpdaemon does not filter control characters. Because of this, some control characters may turn the user's terminal insane. Resolution: Control characters are replaced with blanks in rlpdaemon. 7. Data is not getting printed due to control file corruption in the remote machine. This is because of the buffer overflow for the array which stores title in rlpdaemon. Resolution: The array size which contains the title on the remote printer is increased to hold the title length specified in the RFC1179. 8. Spooler stops processing requests in between because, the file which contains the request information (outputq) is not getting compressed when a large number of requests are given. This occurs because of the missing return statement in a function. Resolution: The return statement is added in the appropriate function. PHCO_18779: According to RFC-1179, the messages from the remote printer daemon could be anything, but the starting and ending of these messages should adhere to the correct protocol. Portions where unrequired checks are being made to the messages resulting in the "Status corrupt" messages have to be removed. Resolution: Unrequired checking in rlpstat(1) has been removed to avoid the "Status corrupt" message. Any message got from the remote printer daemon is printed as is got. PHCO_17713: 1. Since the sequence numbers of BSD(3 digit) and for non BSD (4 digits) are not in proper format, removal of data files results in a failure after an lpalt operation from PHCO_13133 onwards. 2. As the array size for the printer name was not uniform, cancel(1) of requests greater than 14 characters was resulting in a failure. 3. cancel(1) does not set and pass on the correct exit values. As a result of this, the exit value remains "0" even after the command fails. 4. rlpdaemon lockfiles remain with FQDNs after patch PHCO_12894 Resolution: 1. The formatting of the seqno while copying them onto a buffer has been corrected to take care of BSD and non BSD sequence numbers. 2. The value of DESTMAX denoting the Max chracters allowed for a printer name has been made uniform to accept 14 character names. 3. The exit value in cancel(1) is now set and passed on properly to ensure the correct value is got in case of the command failure. 4. Check for the lock before initialising the lckfile string. PHCO_16724: During spooler startup, the write offset in the pstatus file was not updated properly. PHCO_16294: lpsched used to hang intermittently for remote requests when remote printer/system was down. PHCO_16106: lp(1) was not linking files to the SPOOL directory as the complete path of the directory was not specified. PHCO_14431: 1. The model scripts corresponding to P405, HP5000D640 were not there. 2. Since the LANG variable was incorrectly passed to the control file, the "Invalid options" error message was appearing on the banner. PHCO_14029: 1. Spooler was only deleting the data files whose names start with "d". 2. with LANG set, lpsched was improperly handling repeated calls to catgets(). 3. Due to sharing of same fd's of catalogue message files between parent and child processes in lpsched, a SIGSEGV used to cause coredumps intermittently. PHCO_13133: 1) lpstat was not giving the correct output for certain sequences of printer/class lists due to incorrect referencing of both pstatus and qstatus files. 2) lpsched was not clearing the data files present in the spooler directory due to descripencies in the names of these files, caused by the lpalt. PHCO_12894: 1. Jobs submitted to a LP remote printer that points to a "disabled" remote HPDPS printer are discarded. 2. When more than one jobs, whose job sequence numbers are the same, are simultaneously submitted from the same host to the same remote printer through RFC1179 protocol, rlpdaemon(1M) fails to spool the jobs on the remote system due to data/control file name collision. 3. All jobs from any HPDPS printers are spooled under the /usr/spool/lp/request/PDRequest by rlpdaemon(1M). This single PDRequest directory increases the chance of file name collision due to simultaneous job submission. PHCO_11462: 1. Cancelling a lp job with empty control file clears the whole queue. 2. Printer gets disabled on cancelling a printing job. PHCO_10891: 1. "lpstat -i -o" doesn't inhibit the reporting of the remote status if a HPDPS printer name is specified. This problem happens only when the HPDPS patch, PHCO_10608, is installed on the system. Because of this, CDE print manager doesn't work correctly for HPDPS printers. PHCO_10749: 1. LP-spool hang or qstatus corrupt when /var full log says:Bogus request 2. Parent lpsched hangs when lpalt is used to move a request. 3. Model scripts does not handle SIGTERM any more. 4. lpsched introduced 5 sec delay between prints at 10.20 PHCO_8488: 1. lpsched hangs under FIFO full condition 2. Printers go idle even when requests are present in the queue 3. Jobs not printed when remote host(IBM) immediately snaps connection. 4. If a BSD system spooler sends a '\001' to rlp(1) after the control file has been sent, rlp(1) simply ignores the '\001' and removes the entry. 5. lp, cancel, and lpstat hang when forwarding jobs or requests to HPDPS. 6. Implicit requirement that a rlpdeamon client's remote printer name must be the same as its local pseudo name.
