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_access(0x8187fc8,0x4,0x8187fc8,0x6,0x0,0x6) ERR#2 'No such file or directory'
70291: linux_access(0x8187fc8,0x4,0x8187fc8,0x6,0x0,0x6) ERR#2 'No such file or directory'
70291: linux_access(0x8187fc8,0x4,0x8187fc8,0xe,0xb,0x6) ERR#2 'No such file or directory'
70291: linux_access(0x8187fc8,0x4,0x8187fc8,0xe,0xffffae84,0x6) ERR#2 'No such file or directory'
70291: linux_access(0x8187fc8,0x4,0x8187fc8,0xe,0xffffae84,0x6) ERR#2 'No such file or directory'

70291: linux_access(0x8187fc8,0x4,0x8187fc8,0xffffae84,0xe,0x6) = 0 (0x0)
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,
Paul Schenkeveld
