CD-ROM gone funny with 1.1.57

CD-ROM gone funny with 1.1.57

Post by Marcus Bainbrid » Tue, 01 Nov 1994 07:48:04

My Panasonic CD drive is only partially recognised now that I've patched in
1.1.57 of the kernel.  If I type   dir /cdrom   everything is normal, and
the full directory is listed.  However, if I now    cd /cdrom   first, dir
produces   ls: .: No such file or directory

I recompiled without making any changes just to make sure it wasn't my
fault.  I'm now going back through the patches to see where the error was
introduced.  More details when I have them.


1. Kernel change summary 1.1.57 -> 1.1.58

These changes are archived on

Ramdisk can now be formatted as ext2 fs or minix instead of just minix.
Serial driver changes:
        * serial.c (rs_close): Add a timeout to the transmitter flush
                loop; this is just a sanity check in case we have flakey
                (or non-existent-but-configured-by-the-user) hardware.
        * tty_io.c (tty_fasync): When asyncronous I/O is enabled, if the
                process or process group has not be specified yet, set it
                to be the tty's process group, or if that is not yet set,
                to the current process's pid.
        * n_tty.c (n_tty_receive_room): If we are doing input
                canonicalization, let as many characters through as
                possible, so that the excess characters can be "beeped".
Ext2 changes:
        - Some cleanups in the error messages (some versions of syslog contain
          a bug which truncates an error message if it contains '\n').
        - Check that no data can be written to a file past the 2GB limit.
        - The famous readdir() bug has been fixed by Stephen Tweedie.
Security checks on fcntl(0,F_SETOWN,some_root_process) made more
        liberal (match against uid, euid, session instead of always
        needing to be root).
Oops, did assignment instead of equality test in isofs name comparison.
Added call to fsync a umsdos file.
Oops, missed a couple of places where notify_change() needed to be
        changed in umsdos fs.
Oops, forgot to update date of ext2fs when version changed in 1.1.57.
non blocking connect fail gets the error code right.
select() not reporting read ok after an urgent read fixed.
