[User-mode-linux-user] Problems with 2.3.99-pre8

[Iustin P. <iu...@em...>]

Hi to all!
Jeff, you proposed adding a file in arch/asm-um/highmem.h, in order for the
correct file to be included. But the patch available on sourceforge doesn't
include or modify any file called highmem.h . So this change does nothing for
me, it's the same thing: usermode kernel hangs in select.

And a second problem: when ifconfig'ing the umn, it gives me this error:
get_ptr : Couldn't grant pty - errno = 128
umn : Failed to open pty
which I traced to file /usr/src/uml/arch/um/kernel/user_util.c:406
in grantpt(fd). One error I see is that the printk regarding this grant pty
error doesn't have the errno as a parameter, which probably causes invalid
printing of the error code. I tried to add it and recompile, but the highmem.h
problem prevents me to boot with my kernel. I tried to look in the glibc source
code for the reason why grantpt would fail, but I didn't manage my way around.

Also, could the ppp module be compiled? This, combined with the serial port
which is already available (equivalent to a null-modem cable) would give us the
possibility to use ppp on the both sides to establish networking.

Thanks for a cool/useful program!
Iustin Pop
