[uml-user] memory.c:49: asm/tlb.h: No such file or directory, depreciated kernel options and networking

[Ookhoi <oo...@dd...>]

Hi,

If I try to compile a 2.4.2 kernel patched with -ac18 and
uml-patch-latest (11 Mar), I get this error:

make[1]: Entering directory `/usr/src/linux/mm'
make all_targets
make[2]: Entering directory `/usr/src/linux/mm'
gcc -D__KERNEL__ -I/usr/src/linux/include -Wall -Wstrict-prototypes -O2 -fomit-frame-pointer -fno-strict-aliasing   -U__i386__ -Ui386 -D__arch_um__ -DSUBARCH="i386" -DNESTING=0 -D_FILE_OFFSET_BITS=64    -c -o memory.o memory.c
memory.c:49: asm/tlb.h: No such file or directory
make[2]: *** [memory.o] Error 1
make[2]: Leaving directory `/usr/src/linux/mm'
make[1]: *** [first_rule] Error 2
make[1]: Leaving directory `/usr/src/linux/mm'
make: *** [_dir_mm] Error 2

If I do a cp include/asm-i386/tlb.h include/asm/. it compiles fine.

I also noted that for networking, uml depends on things in the kernel
wich are depreciated:

Netlink device emulation
CONFIG_NETLINK_DEV
  This option will be removed soon. Any programs that want to use
  character special nodes like /dev/tap0 or /dev/route (all with major
  number 36) need this option, and need to be rewritten soon to use
  the real netlink socket.
  This is a backward compatibility option, choose Y for now.

Ethertap network tap (OBSOLETE)
CONFIG_ETHERTAP
  If you say Y here (and have said Y to "Kernel/User network link
  driver", above) and create a character special file /dev/tap0 with
  major number 36 and minor number 16 using mknod ("man mknod"), you
  will be able to have a user space program read and write raw
  Ethernet frames from/to that special file. tap0 can be configured
  with ifconfig and route like any other Ethernet device but it is not
  connected to any physical LAN; everything written by the user to
  /dev/tap0 is treated by the kernel as if it had come in from a LAN
  to the device tap0; everything the kernel wants to send out over the
  device tap0 can instead be read by the user from /dev/tap0: the user
  mode program replaces the LAN that would be attached to an ordinary
  Ethernet device. Please read the file
  Documentation/networking/ethertap.txt for more information. 

Will we still be able to use uml in kernel 2.5?

And I als find network with uml hard to set up (doesn't work yet, will
play further with it).

I think uml is a great project. :-)
