Missing syscall linux_base-f10 on 8.0-R (amd64)

[Paul Schenkeveld]

Hi,

I'm trying to run an old linux executable on 8.0-R amd64 under
linux_base-f10.  The app (we have no sources) fails when trying to
open a pipe to the lp command.  With truss I see the following:

70291: read(0,"\n",4096)                         = 1 (0x1)
70291: linux_socketcall(0x9,0xffffb424,0x81b0150,0x81b0150,0x81a5ac8,0x6) = 4 (0x4)
70291: linux_socketcall(0xa,0xffffb400,0x81afc08,0x4,0x81a5c9c,0x6) = 12 (0xc)
70291: linux_access(0x8187fc8,0x4,0x8187fc8,0x6,0x0,0x6) ERR#2 'No such file or directory'

70291: linux_open("/some/file",0x0,00) = 6 (0x6)
70291: read(6,"xxxxxx",6)                        = 6 (0x6)
70291: read(6,0xffffafbc,13)                     = 0 (0x0)
70291: close(6)                                  = 0 (0x0)
-- UNKNOWN SYSCALL 331 --
70291: write(2,"\n    ",5)                       = 5 (0x5)

Is this a system call missing in linux_base-f10 or in the kernel part
of the linux emulation?  The app user to run on 6.2-R i386 with
linux_base-fc-4.  We are trying to move to 8.0-R amd64 to get stable
ZFS support.

Thanks,
