This is a function of the shell. BASH supports job control, ash

Today I ventured into build the kernel for Linuc 0.95a with
|
|
GCC 1.40. I edit some of the makefiles so that the -fcombine-regs
|
|
flag was set and I did the make. Everything compiled fine so I decided
|
|
to try it out. I booted up with the new image and everything seems to
|
|
work except for the fact that some of the keyboard keys produce the
|
|
wrong characters (i.e. pressing / produces -). Does anyone know why
|
|
this is happening? Am I supposed to be using GCC 2.0? If so, what
|
|
is the status of GCC 2.0? (Alpha, Beta???), and can it be used reliably
|

with Linux? Thanks,

After ftp'ing a few megs, I installed Linux 0.95a this weekend on my
|
|
machine: Micronics board, 386-20, 2 MB RAM, HGC, 5.25 and 3.5 inch
|
|
drives and a WD 1006 with a Micropolis 70 MB MFM winchester drive.
|
|
(and lots of dust from over three years, but I doubt that counts:)
|
|
|
|
The rootimage was very helpful, I needed only a short while until the
|
|
machine booted the first time with root fs on winchester. Everything
|
|
uncompressed fine and worked on first try.
|
|
|
|
When I copy *really* big files, like creating the swap file, I sometimes
|
|
get "HD timeout" messages. Is this a warning or an error (read: can I
|
|
ignore it)?
|
|
|
|
After years with MINIX, I had to try out what might happen, if I start
|
|
two compilers parallel. I got a trashing machine, as expected :) But
|
|
something else happened as well:
|
|
|
|
Warning, pid 1450 older sibling 10 has mismatched ys link
|
|
Warning, pid 1450 younger sibling 10 has mismatched os link
|
|
|
|
What does that mean? It happens from time to time, if the machine starts
|
|
thrashing.
|
|
|
|
When I try to compile the kernel, compiling fork.c will get aborted by
|
|
"Program got fatal signal 2615". I tried to compile this, and a a few
|
|
more file without -O and finally got an Image file of 215552 bytes. I
|
|
copied this file to /dev/at0 and rebooted the machine. After printing
|
|
the usual information Loading ..... and number of ptys, I got a kernel
|
|
panic from swapper, trying to free unused page or similar (sorry, I'm
|
|
typing from memory). I can give more information, if I didn't make a
|
|
wellknown mistake... I used gcc 1.40 (newgcc) for compiling.
|
|
|
|
btw: Doesn't Linux create a core dump when a program produces a
|
|
segmentation fault?
|
|
|
|
There seems to be no putenv and no regex in the library, right?
|
|
|
|
Everything else seems to work fine, just now I am writing this article with
|
|
Origami, wnews and wmail only needed slightly changes (grrr, MINIX specific
|
|
code). I am impressed of the speed of Linux, if I would have known that
|
|
earlier, I would have changed earlier, no matter how much bugs the older
|
|
versions had and I am really looking forward to the possibility of compiling
|
|

I currently have two curses libraries, BSD curses which came with Linux
|
|
and a PD curses package, which has its origin in PC curses and ncurses.
|
|
|
|
I think BSD curses is awful old and 7 bit characters are a pain. On the
|
|
other side, it is standard.
|
|
|
|
The PD curses has a few minor bugs, but I used it under MINIX for example
|
|
to compile sokoban, rogue and a few other games. The weak points are the
|
|
print/scan functions (no ANSI way to pass arguments) and such things. Its
|
|
features are support of ACS characters like SYS V and 8 bit characters with
|
|
standout, underline, bold etc.
|
|
|
|
If there is no other curses library, I will work more on this PD curses,
|
|
because I really need a curses lib. Any comments?

Kernel support for networking doesn't have to be all-or-nothing. A
|
|
number of people (Clark, for one) have suggested putting just
|
|
multiplexing facilities in the kernel, and then doing the rest as a
|
|
library within the destination user process. For TCP/IP this would
|
|
mean putting all of IP and the connection control block lookup for TCP
|
|
into the kernel.
|
|
|
|
Some advantages are:
|
|
|
|
- performance - you don't have to go kernel -> user process 1 -> user
|
|
process 2
|
|
|
|
- debugging is easier than full kernel implementation, although not
|
|
as easy as full user process method.
|
|
|
|
- "standard" TCP, RPC, etc. be supplied in shared library, but
|
|
applications would be able to use custom tuned implementations as
|
|
well. (see IEEE Network 1/92, article on RPC performance, for a
|
|
good example of why you might want this)
|
|
|
|
Just a thought...

|
|
|

Some bizarre is going on with the HD timeouts, I think. I get the
|
|
same problem running GCC (DJGPP) under DOS, which is also 32bit.
|
|
Every so often, I get a ``not ready error reading drive C:'' Of
|
|
course, that absurd. I also get the same error when running some
|
|
programs compiled with GCC (DEMACS, e.g.). BTW, my machine is a Dell
|
|
325D ('385 at 25MHz), with a Seagate (yuk) 110ish HD (IDE).
|
|
|
|
The bottom line is there's no reason the HD should timeout, or be not
|
|
ready. I've spoken to Dell repeatedly about this matter. The first
|
|
time they told me the software was as fault. The second time they
|
|
told me there was a problem in their BIOS. When they sent me the new
|
|
BIOS, the problem changed its manifestation, but was not repaired.
|
|
(Now whenever I get the error, the HD jumps to track 470 and stays
|
|
there.) I spoke with tech support yesterday (but to my great surprise
|
|
got someone who didn't speak enough English to communicate. What's
|
|
happening to Dell?) He told me that one of their super-gurus said
|
|
it was either a problem on the motherboard or a problem with the HD.
|
|
They will replace the motherboard me.
|
|
|
|
Whatever the case, something screwy is going on. I suspect problems
|
|
of a similar nature may be plaguing Linux.

This brings up something I've been meaning to ask. Are you (or anyone

else) planning on keeping a set of "recommended" kernel patches, and

|
possibly even fully patched set of sources. I'm mostly thinking about

bug-fixes here but we might want to also include an alternate set of
|
|
"expirmental" patches (and source) with the caveat that they may or
|
|
may not be included (at Linus' discretion) in the next release.
|
|
|
|
What I'm hoping to avoid is the "patch anxiety" experienced by users
|
|
like me who get a bit antsy when their kernel reaches a certain level
|
|
of patches. I remember when the patches to 0.12 started to overlap.
|
|
They appeared to work but I didn't feel very secure.

Check in keyboard.s - looks like you have not specified US keyboard;
|
|
early kernel sources have specified Finnish keyboard.

I actually got 386BSD up and running. It is a *MESS*. People have compared
|
|
it to linux a year ago. Perhaps. Perhaps even worse. I recommend that
|
|
anyone interested in 386BSD test it (yeah, blow away your hard drive, see if
|
|
I care), then watch it fail, "extra interrupt", hang, core dump, etc etc.
|
|
I am sure that in time, it will develop into a "good thing", but right now..
|
|
|
|
NOT!
|
|
|
|
My thoughts: Get the WD8003 code out of 386BSD, get TCP/IP working. Linux
|
|
beats the pants off of 386BSD at this point.

Bravo.
|
|

Long Live Linus and Linux.

Subject: Bug in putpwent()
|

|
|
|
|
The other day I was building a passwd utility for inclusion in my next
|
|
release of the init/getty/login package (poeigl). During this I discovered
|
|
that the putpwent() routine in libc was wrong. It fails to write the pw_dir
|
|
field.
|
|
|
|
After I fixed this it seems to work fine.
|
|
|
|
When are we going to see sources for an updated 0.95a libc? I haven't seen
|
|
sources for libc since 0.12 went out.
|
|
|

Subject: minor linux 0.95a bugs
|
|
Date: 23 Mar 92 16:43:50

Hi Linuxers,
|
|
|
|
While playing around with the Linux0.95a images I found a few minor bugs.
|
|
|
|
- At boot-time, when I am asked if I wish to select any VGA mode or
|
|
just press any key to stay at 80x25, I noticed that some keys will
|
|
keep the system from reading the root-image (i.e. the arrow-down key).
|
|
BTW: In the upper right corner appeared EGAm instead of EGAc...
|
|
|
|
- The backspace-problem appears even on a virtual console where backspace
|
|
worked at first when I log out and try to log in again.
|
|
|
|
- Has anybody tried to fill up the process table yet? O.K. this is what
|
|
I tried: I started about 55 shells from the same virtual console :-)
|
|
The last shell I started neither gave me a prompt nor printed any
|
|
error message. Pressing ScrollLock showed that I had 58 processes.
|
|
Switching to another virtual console where I also was logged in I still
|
|
could start processes, but after a few seconds I got error messages
|
|
like memory fault or out of memory or out of swap space (certainly,
|
|
running from diskettes, I didn't have swapping enabled).
|
|
Maybe I just ran out of memory but I think even then, this behaviour
|
|
is, if not a bug, a little bit strange.
|
|
BTW: We should get a /bin/kill in the root image :-}
|
|
|
|
- One more bug: If I press ScrollLock and stay on the key for a few seconds,
|
|
I get a few dumps from the process table, then the kernel hangs and
|
|
prints:
|
|
|
|
general protection: 0014
|
|
EIP : 0008:0000c166
|
|
EFLAGS: 00010086
|
|
fs: 0010
|
|
base: 0076ffff, limit: 00000018
|
|
Pid: 0, process nr: 0
|
|
8e e0 ff 05 b0 a1 02 00 b0 20
|
|
Kernel Panic: free_page_tables called with wrong alignment
|
|
In swapper task - not syncing
|
|
|
|
Looks like a real bug, doesn't it?
|
|
|
|
I was running Linux on a 386sx 20Mhz board with 32kB cache and 4 Mb RAM.
|
|
|
|
Linux is really great, thank you Linus and all the others!
