--001a114922d246065105616ac0ff Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable Hello all, I am trying to build PVH mini-os with libc support. These are the steps I have followed so far: 1. Xen repo (master: commit id: d2f86bf604698806d311cc251c1b66fbb752673c) 2. mini-os repo (master: commit id: 0b4b7897e08b967a09bed2028a79fabff82342dd) 3. Made the following modifications in the xen repo to build c-stubdom: diff --git a/stubdom/Makefile b/stubdom/Makefile index f45eeabd8b..aa21904019 100644 --- a/stubdom/Makefile +++ b/stubdom/Makefile @@ -61,7 +61,7 @@ TARGET_CPPFLAGS +=3D -I$(XEN_ROOT)/xen/include TARGET_LDFLAGS +=3D -nostdlib -L$(CROSS_PREFIX)/$(GNU_TARGET_ARCH)-xen-elf/lib -TARGETS=3D$(STUBDOM_TARGETS) +TARGETS=3D$(STUBDOM_TARGETS) c STUBDOMPATH=3D"stubdompath.sh" genpath-target =3D $(call buildmakevars2file,$(STUBDOMPATH)) diff --git a/stubdom/c/minios.cfg b/stubdom/c/minios.cfg index e69de29bb2..cacde0cbca 100644 --- a/stubdom/c/minios.cfg +++ b/stubdom/c/minios.cfg @@ -0,0 +1,18 @@ +CONFIG_PARAVIRT=3Dn +CONFIG_START_NETWORK ?=3D y +CONFIG_SPARSE_BSS ?=3D y +CONFIG_QEMU_XS_ARGS ?=3D n +CONFIG_PCIFRONT ?=3D n +CONFIG_BLKFRONT ?=3D y +CONFIG_TPMFRONT ?=3D n +CONFIG_TPM_TIS ?=3D n +CONFIG_TPMBACK ?=3D n +CONFIG_NETFRONT ?=3D y +CONFIG_FBFRONT ?=3D y +CONFIG_KBDFRONT ?=3D y +CONFIG_CONSFRONT ?=3D y +CONFIG_XENBUS ?=3D y +CONFIG_XC ?=3Dy +CONFIG_BALLOON ?=3D n 4. $ cd $(XEN_ROOT) 5. $ make; sudo make instal 6. Reboot host 7. $ cd $(XEN_ROOT)/stubdom 8. $ make c-stubdom 9. Used the following configuration file to create the domain: type=3D"pvh" memory=3D512 vcpu=3D1 name=3D"minios" kernel=3D"/home/balvisio/xen/stubdom/mini-os-x86_64-c/mini-os.gz" When I create the domain it crashes during the bootstrap process with a triple fault. The following are the dmesg logs (note that "Xen Minimal OS (hvm)!" is printed and the domain crashes after that line in setup.c): (XEN) grant_table.c:1688:d0v3 Expanding d360 grant table from 0 to 1 frames (XEN) HVM360 save: CPU (XEN) HVM360 save: PIC (XEN) HVM360 save: IOAPIC (XEN) HVM360 save: LAPIC (XEN) HVM360 save: LAPIC_REGS (XEN) HVM360 save: PCI_IRQ (XEN) HVM360 save: ISA_IRQ (XEN) HVM360 save: PCI_LINK (XEN) HVM360 save: PIT (XEN) HVM360 save: RTC (XEN) HVM360 save: HPET (XEN) HVM360 save: PMTIMER (XEN) HVM360 save: MTRR (XEN) HVM360 save: VIRIDIAN_DOMAIN (XEN) HVM360 save: CPU_XSAVE (XEN) HVM360 save: VIRIDIAN_VCPU (XEN) HVM360 save: VMCE_VCPU (XEN) HVM360 save: TSC_ADJUST (XEN) HVM360 restore: CPU 0 (d360) Bootstrapping...

In addition to this I have noticed that even fter installing Xen and rebooting the host, the initial =E2=80=98xl dmesg=E2=80=99 logs show that Xen tries to launch unsuccessfull= y domains created before the system was rebooted. I am not sure if these two issues are related but I pasting a trace of the logs (these dmesg logs are seen just after rebooting the host before attempting anything else): root@debianxen:/home/balvisio# xl dmesg (XEN) parameter "placeholder" unknown!

Hello= all,

I a= m trying to build PVH mini-os with libc support. These are the steps I have followed so far:

1. Xen repo (master: commit id:=C2=A0d2f86bf604698806d311cc251c1b66fbb752673c)

=

2. mini-os repo (master: commit id:=C2=A00b4b7897e0= 8b967a09bed2028a79fabff82342dd)<= span style=3D"color:black">
3. Ma= de the following modifications in the xen repo to build c-stubdom:

4. $ cd $(XEN_ROOT)

5. = $ make; sudo make instal
6. Reboot host
7. $ cd $(XEN_ROOT)/stubdom=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0
8. $ make c-stubdom
9. Used the following configuration file to create the domain:

=C2=A0

type= =3D"pvh"

memo= ry=3D512

vcpu= =3D1

name= =3D"minios"

kern= el=3D"/home/balvisio/xen/stubdom/mini-os-x86_64-c/mini-os.gz"

=C2= =A0


When I create the domain it crashes during the bootstrap process with a triple fault. The following are the dmesg logs= (note that "Xen Minima= l OS (hvm)!" is printed and the domain crashes after that lin= e in setup.c):

Any help on this would be greatly appreciated. In addition to this I have noticed that even fter installing Xen and rebooting= the host, the initial =E2=80=98xl dmesg=E2=80=99 logs show that Xen tries to la= unch unsuccessfully domains created before the system was rebooted. I am not sure if these two issues are related but I pasting a trace of the logs (these dmesg logs are = seen just after rebooting the host before attempting anything else):

Any help on this would be greatly appreciated.


You will need to disassemble your minios kernel and see which instruction is at 0x56fc8.  (Chances are, it will be `jmp %r15`).

The content of %r15 looks like x86 opcode, which is reminiscent of the XTF relocatability bugs.  Make doubly sure you are compiling with -fno-pic and link with -no-pie.

The kern dump in this case points to the stack: 5e: e8 00 00 00 00 callq 63 0000000000000063 : ... 6b: 90 nop 6c: 90 nop 6d: 90 nop I am not familiar with the XTF relocalability code. Any pointer or suggestion at this point would be again appreciated.

Hello Andrew,

Thanks. Yup, you were right. I did an objdump of the kernel and found the offending inst= ruction 0x5cfcb to be callq *%r15 in the console_print function (see below):<= /span>

I added the options =E2=80=93fno-pic to= TARGET_CFLAGS and TARGET_CPPFLAGS and =E2=80=93no-pie to TARGET_LDFLAGS and recompile the ker= nel. Now, the kernel carshed at instruction 0x673bb in the run_idle_thread function:<= span>

Finally, just to try I commented out th= e run_idle_thread function and the kernel crashed at the very beginning at 0x63. The kern dum= p in this case points to the stack:

I am not familiar with the XTF relocala= bility code. Any pointer or suggestion at this point would be again appreciated.

Any help on this would be greatly appreciated.


 You will need to disassemble your minios kernel and see which instruction is at 0x56fc8.=C2=A0 (Chances are, it will be `jmp %r15`).<= br>
The content of %r15 looks like x86 opcode, which is reminiscent of the XTF relocatability bugs.=C2=A0 Make doubly sure you are compiling with -fno-pic and link with -no-pie.

Hello Andrew,

 

Thanks. Yup, you were right. I did an objdump of the kernel and found the offending instruction 0x5cfcb to be callq *%r15 in the console_print function (see below):


Answering out of order...

I am not familiar with the XTF relocalability code. Any pointer or suggestion at this point would be again appreciated.


XTF is the Xen Test Framework, a microkernel project for testing purposes.

http://xenbits.xen.org/gitweb/?p=xtf.git;a=summary
http://xenbits.xen.org/docs/xtf/

Amongst other things, it runs as a set of regression tests for all new code introduced into upstream Xen.

All I meant by that statement was "I recall bugs like this", which is why I made the blind guess at your offending opcode being `jmp *%r15`.

   56fdb:   41 5e                   pop    %r14

   56fdd:   41 5f                   pop    %r15

   56fdf:   5d                      pop    %rbp

   56fe0:   c3                      retq

 

 

I added the options –fno-pic to TARGET_CFLAGS and TARGET_CPPFLAGS and –no-pie to TARGET_LDFLAGS and recompile the kernel. Now, the kernel carshed at instruction 0x673bb in the run_idle_thread function:

 

00000000000673ac <run_idle_thread>:

   673ac:   55                      push   %rbp

   673ad:   48 89 e5                mov    %rsp,%rbp

   673b0:   48 8b 05 00 00 00 00    mov    0x0(%rip),%rax        # 673b7 <run_idle_thread+0xb>

   673b7:   48 8b 60 10             mov    0x10(%rax),%rsp

   673bb:   ff 70 18                pushq  0x18(%rax)

   673be:   c3                      retq

   673bf:   5d                      pop    %rbp

   673c0:   c3                      retq

 

 

Finally, just to try I commented out the run_idle_thread function and the kernel crashed at the very beginning at 0x63. The kern dump in this case points to the stack:

 

      5e:   e8 00 00 00 00          callq  63 <stack_start>


Both the above mov instruction at 0x673b0 and this call instruction with a 4-byte displacement of 0 look suspiciously like they are waiting for relocation, as displacements of 0 are exceedingly rare (there are more efficient ways to encode such operands).

Therefore, I don't think you've succeeded in preventing your binary from being relocatable.

      6d:   90                      nop

Any help on this would be greatly appreciated.


 You will need to disassemble your minios kernel and see which instruction is at 0x56fc8.  (Chances are, it will be `jmp %r15`).

The content of %r15 looks like x86 opcode, which is reminiscent of the XTF relocatability bugs.  Make doubly sure you are compiling with -fno-pic and link with -no-pie.
