Rod Sheppard created ticket #10
D4GL (4js) COFF get segmentation violation
-
Iv'e got a work around by making /usr/fgl2c an tmpfs at startup, so something to do with the size of the data staructures or inodes being returned on this particular VM. where tge root fs is /dev/nvme0n1p2 60G 6.5G 54G 11% / I created my o\wn test AWS rhel8 machine (default free image), and it had no issue.

sh-4.2# file /usr/fgl2c/bin/fglWrt /usr/fgl2c/bin/fglWrt: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), statically linked, stripped sh-4.2# this also works fine on my inhouse rhel8 but not on the AWS rhel8

Since the origianl post, I have also found that 1 32bit satically linked linux ELF binary fglWrt that is the the user license manager that comes with the informix 4gl also exhibits a similar problem when run with the -u option to verify users. sh-4.4# fglWrt -u ERROR(-6071):Cannot use directory '/usr/fgl2c/lock'. Check FGLDIR and verify if access rights are 'drwxrwxrwx'. running a system trace.... sh-4.4# (strace /usr/fgl2c/bin/fglWrt -u 2>&1) >fglWrt_u.strace fglWrt_u.strace attached, see line 53...

forgot to add.. these are the lines in the trace files I believe where I'm hitting the problem.. In callextdet_22220107.strace line 481: read(7, ERROR(-6071):Cannot use directory '/usr/fgl2c/lock'. In ibcs-us_callextdet_20220107.trace line 530: read(7, 0x00475A4C, 1024) read returns 1 (edx:1)

Hi Russell, That did the trick, there it was plain and clear in the man page, sorry should have read the man page.

Wait() system call is not waiting

Found the issue, there was a # out entry in /etc/passwd that had the number of ":' separrateors accidentally changed, So thing to do with ibcs-us Please close

I will attempt to create a tar ball of a chroot with the error, What Ive determined from testing is that if the test user is withon 1024 bytes (1 read ) of /etc/passwd then the 4gl worrks fine. the production box is always doing only 1 read of 1024 bytes on the open /etc/passwd wh\ere as the Dev box loops on the read () 1024 bytes of /etc/passwd unitil it finds the line matching getuid()

Informix D4GL having perms issue
-
Thanks Russel thats brilliant. I have tested and I also see the segfault 4GL RUN / C system()l has been fixed. Thee xternal code runs, and thewn the program continues fine. Tesedt test 4gl tst9.42e , and test C code tst10, as well as real 4GL program that first showed the issue. I've been doing a bit of testing over the last month, and sofar have not come across any other issues. Thanks for all the effort to fix this

Just realised you wonyt be able to run the binary, becaus tyou need a 4gl runtime installed. -- reply above this line -- Rodney Sheppard Software Engineer - Development Manager Trans-Mit Pty.

Hi Russel, On my SCO 4gl dev box I alterred the code to comment ot the exec (4GL RUN command). The seg failt then moved to the next RUN command in the code. So I created a simple 4GL test program which exhibits the fault. (attached) tst9.4 is the 4gl source code tst9.42c is the c code generated by the 4GL compiler, tst9.42e is the binary. I have also setup a login for you on my rHEL 7 box if you want -- reply above this line -- Rodney Sheppard Software Engineer - Development Manager Trans-Mit Pty....

Thanks Russel I will see if I can convert and save the 4gl src to its intermediate ESQL/C code to see what it is doing. The code where it is failing is part of a 4GL library, the partriuculay source sends update date to remote systems, and records local session logs I will look at enabling a port forwading from the internet to ssh login on the RHEL 7 box.

Hi Russel, By using a simple socket test progrom I determined that sockets are working ok with ibc-us, and the database connection issue was due to a database version iussue with the apps, which required the configuration of a relay modules which is now working. Nit sure if ipc connection are working because I think this was also failing du to a database version issue. But whith socket connections working to the DB, I don't need ipc. I do have a segmentaion violation issue with one of the apps where...

Thanks Russell Very helpful information, I swill spend some time taking a look at the code using the informartion you have given. I will try runing a trace on e existing binary in RHEL7. to see igf I can spt anythinf. and when I get some TOIme I will setipo a RHEL 8 dev box, and hopefiull I can compile the source, so I can debug. the socksys.c code.

Thanks Russel, When I get time, I will setup a RHEL 8 dev box and see I can get the source to compile on it. I can then use it as a test ben, I know 'C', but nothing about LInux kernel, or linux system cal, but If you pint me the the source files of inetrest, I will take a llok. How aboput the IPC option?

I made /dev/socksys and tried the tcp/ip socket connet to the DB without succees, I also have the option to connect to the Informix DB via IPC, whxch I also tried without success I know the iPC worked on the ibc3.s kernal modules on RHEL 5, is the IPC system call still supported on ibcs-us, and if so is there anythong I need to do to confiure it?

A big thanks Russell, I loaded the binary from us_4.1.4-1_amd64.deb onto my RHEL 7 dev box (kernel 3.10.0-957.21.3.el7.x86_64) and tested a static SCO coff. (a simple file checksum toot), which worked ok I will move on to test somethig that uses sockets and informix db access. Rod
