Hi Bruce,

 Thank you for your review.  I fixed lines you pointed out and
 attached a patch candidate.  I will show each change line by line in

br I don't like warnings about hackish but correct code like the previous
br version of the above.  Does the compiler actually complain about
br comparing

 Yes, this part caused the following warning:

  different signs: 'int' and 'u_long' (aka 'unsigned long')
  [-Werror,-Wsign-compare]

br If you are going to change the range check, then rearrange the code.
br It
br was arranged to set sockbufsize before the value is known to fit so
br that
br non-fitting values can be checked.  With range checking on the
br
br original
br value, it is more natural to not do the assignment until after the
br check has passed.  Then the cast should be unnecessary since a smart
br compiler would see from the range check that the assignment can't
br overflow.

br Backwards.  The RHS should be cast to ptrdiff_t.  Pointer difference

I tested this.  I couldn't get it to fail, but noticed another type
error and re-noticed associated style bugs.  The packet format is a
network 32+32-bit timeval, and that is what is copied, but the bounds
check is for a host timeval.  On i386, network timeval == host timeval
so there is no problem.  On other 32-bit systems with 32+32-bit
timevals, ntohl() fixes up the byte order if necessary.  But on N-bit
systems with 64-bit timevals, ping -s 8 is broken.  It should send a
32+32-bit timeval but either doesn't send it or can't receive it.  Such
systems include:
- most 64-bit systems.  All supported ones.  Most have a 64-bit time_t,
  and if they didn't then all supported ones have 64-bit longs so a
  timeval would consist of a 32-bit time_t, 32 bits of padding, and a
  64-bit long.  ping -s 15 doesn't work on these systems, but ping -s 16
  does.
- 32-bit systems with 64-bit time_t.  All supported ones have only 32-bit
  32-bit longs and probably have no padding, so they have 96-bit time_t
  and ping -s 12 would work.

ping -s 8 worked on i386 in my simple tests because phdr_len is normally
0 (I don't know how to make it nonzero).  The full packet size is then
36.  This consists of hlen = 20, ICMP_MINLEN = 8, phdr_len = 0, and a
payload consisting of the network 8-byte timeval.

The style bugs here are that there is a macro TIMEVAL_LEN that is used in
some places to obfuscate the problem.  I don't know much about networking
but have hacked on ping a bit and have old code with comments about this:

% diff -u2 ping.c~ ping.c
*** ping.c~ Sat Apr 10 12:10:59 2004
--- ping.c  Sat Apr 10 12:11:00 2004

% + */
%  #define  TIMEVAL_LEN ((int)sizeof(struct timeval))
%  #define  MASK_LEN(ICMP_MASKLEN - ICMP_MINLEN)

The obfuscation has increased in -current.  The above is broken since it
uses host timevals.  This has been fixed in -current by replacing 'timeval'
by 'tv32', but that increases the obfuscation because the macro still
looks like it is for a host timeval.

Note that the macro already has a cast to int in it (presumably to fix
warnings), so changing the patch to use it will fix both problems.  But
I don't like the obfuscation of that.  It is good practice to use
sizeof(var) instead of sizeof(typedef_name) like the code does now.
This gives a better chance of applying sizeof() to the right variable
although that is not done now.  It was done in the old version that was
broken by using host timevals.  That version was consistently broken --
it didn't have tv2, and it both the sizeof and the copy were done on tv1.

Further review showed that TIMEVAL_LEN is used a lot and is clearer
than '(int)sizeof(struct tv32)' all over.  Just rename it to something
like NTIMEVAL_LEN so that it is clear that it is for a network timeval.

Grepping for sizeof shows just one place where sizeof() is applied to
struct timeval.  This allocates space for a message.  I think this
should use struct tv32 too, but allocating more space than is needed
and sending a larger message than needed is fairly harmless.  Only
6 out of 32 lines have the style bug of following sizeof by a space.
All of these also have the style bug of not parenthesizing the arg.

ping6.c doesn't have TIMEVAL, and also doesn't seem to have the bug
-- ping6 -s 8 works on freefall.

I don't like changing old code like that.  Makes it hard to see
important changes.  You actually changed u_int8_t to u_char.

Log:
  Add vxlan interface
  
  vxlan creates a virtual LAN by encapsulating the inner Ethernet frame in
  a UDP packet. This implementation is based on RFC7348.
  
  Currently, the IPv6 support is not fully compliant with the specification:
  we should be able to receive UPDv6 packets with a zero checksum, but we
  need to support RFC6935 first. Patches for this should come soon.
  
  Encapsulation protocols such as vxlan emphasize the need for the FreeBSD
  network stack to support batching, GRO, and GSO. Each frame has to make
  two trips through the network stack, and each frame will be at most MTU
  sized. Performance suffers accordingly.
  
  Some latest generation NICs have begun to support vxlan HW offloads that
  we should also take advantage of. VIMAGE support should also be added soon.

Re: svn commit: r273331 - in head: sbin/ifconfig share/man/man4 sys/conf sys/modules sys/modules/if_vxlan sys/net sys/sys

2014-10-20 Thread Adrian Chadd 
Hi,

Can you please create a PR that says something like review vxlan code
for RSS after de-capsulation and assign it to me?

I'm going to have to insert a hash recalculation after decapsulation
but I'm too busy at the moment to do it.

Thanks,

 Log:
   Add vxlan interface

   vxlan creates a virtual LAN by encapsulating the inner Ethernet frame in
   a UDP packet. This implementation is based on RFC7348.

   Currently, the IPv6 support is not fully compliant with the specification:
   we should be able to receive UPDv6 packets with a zero checksum, but we
   need to support RFC6935 first. Patches for this should come soon.

   Encapsulation protocols such as vxlan emphasize the need for the FreeBSD
   network stack to support batching, GRO, and GSO. Each frame has to make
   two trips through the network stack, and each frame will be at most MTU
   sized. Performance suffers accordingly.

   Some latest generation NICs have begun to support vxlan HW offloads that
   we should also take advantage of. VIMAGE support should also be added soon.

New Revision: 273334

Log:
  Fully support constructors for the purpose of code coverage analysis.
  This involves:
  1.  Have the loader pass the start and size of the .ctors section to the
  kernel in 2 new metadata elements.
  2.  Have the linker backends look for and record the start and size of
  the .ctors section in dynamically loaded modules.
  3.  Have the linker backends call the constructors as part of the final
  work of initializing preloaded or dynamically loaded modules.
  
  Note that LLVM appends the priority of the constructors to the name of
  the .ctors section. Not so when compiling with GCC. The code currently
  works for GCC and not for LLVM.

Uhm? LLVM here creates .ctors section, nothing is appended. Can you be more
specific on what you're seing?

svn commit: r273338 - in head/sys: amd64/amd64 sys x86/include

2014-10-20 Thread Neel Natu 
Author: neel
Date: Mon Oct 20 18:09:33 2014
New Revision: 273338
URL: https://svnweb.freebsd.org/changeset/base/273338

Log:
  Merge from projects/bhyve_svm all the changes outside vmm.ko or bhyve 
utilities:
  
  Add support for AMD's nested page tables in pmap.c:
  - Provide the correct bit mask for various bit fields in a PTE (e.g. valid 
bit)
for a pmap of type PT_RVI.
  - Add a function 'pmap_type_guest(pmap)' that returns TRUE if the pmap is of
type PT_EPT or PT_RVI.
  
  Add CPU_SET_ATOMIC_ACQ(num, cpuset):
  This is used when activating a vcpu in the nested pmap. Using the 'acquire'
  variant guarantees that the load of the 'pm_eptgen' will happen only after
  the vcpu is activated in 'pm_active'.
  
  Add defines for various AMD-specific MSRs.

 Uhm? LLVM here creates .ctors section, nothing is appended. Can you be more
 specific on what you're seing?

Go to a module build directory (I picked uart) and build on amd64:

% make DEBUG_FLAGS=-ftest-coverage -fprofile-arcs

Check with objdump:

% objdump -x /usr/obj/usr/src/sys/modules/uart/uart.ko | grep ctors
 16 .ctors.65535  0080      00020320  2**3
 ld  .ctors.65535    .ctors.65535
RELOCATION RECORDS FOR [.ctors.65535]:

As you can see, the section is not called .ctors, but it's called
.ctors.$((65536-priority)).

The priority suffix is removed as part of linking, but on amd64,
kernel modules are relocatables...

FYI,

I hope to merge vxlan to 10-STABLE in a couple of months, but need to
determine how to handle prerequisite commit r272886. There's ways without
it - use a mbuf tag and a reserved field in the inpcb - but it would be
nice if that commit is MFC'able.

   This prevents recursion of vdev_queue_io_done as per r265321 but

   We now use zio_interrupt(zio) and return ZIO_PIPELINE_STOP instead
   of returning ZIO_PIPELINE_CONTINUE from vdev_*_io_start methods.
   
   zio_vdev_io_start now ASSERTS the that vdev_op_io_start returns
   ZIO_PIPELINE_STOP to ensure future changes don't reintroduce
   ZIO_PIPELINE_CONTINUE returns.


Steve,

it seems that the issue is applicable to OpenZFS in general, but unfortunately,
as far as I can see, it's been applied only to FreeBSD.

Now, I see the following bug report and a proposed fix:
https://www.illumos.org/projects/illumos-gate//issues/5244
https://reviews.csiden.org/r/119/

I am not 100% sure, but it seems that those upstream changes could fix the
problem that you've found.

What do you think?
Thanks!

   Cleanup flow in vdev_geom_io_start while I'm here.
   
   Also fix some cases not using SET_ERROR(..)

   Don't return ZIO_PIPELINE_CONTINUE from vdev_op_io_start methods
   
   This prevents recursion of vdev_queue_io_done as per r265321 but

   using a different method as recommended on the openzfs list.
   
   We now use zio_interrupt(zio) and return ZIO_PIPELINE_STOP instead

   of returning ZIO_PIPELINE_CONTINUE from vdev_*_io_start methods.
   
   zio_vdev_io_start now ASSERTS the that vdev_op_io_start returns

   ZIO_PIPELINE_STOP to ensure future changes don't reintroduce
   ZIO_PIPELINE_CONTINUE returns.


Steve,

it seems that the issue is applicable to OpenZFS in general, but unfortunately,
as far as I can see, it's been applied only to FreeBSD.

Now, I see the following bug report and a proposed fix:
https://www.illumos.org/projects/illumos-gate//issues/5244
https://reviews.csiden.org/r/119/

I am not 100% sure, but it seems that those upstream changes could fix the
problem that you've found.

What do you think?

Yep very similar change overall.

The only real difference is they changed the vdev_op_io_start call to a 
void and return stop direct from zio_vdev_io_start.


The result should be identical and it will be easy to merge the upstream 
change when it gets committed.


Shame that wasn't suggested when I posted my suggested patch ;-)

Regards
Steve

URL: https://svnweb.freebsd.org/changeset/base/273356

Log:
  Fix a race in pmap_emulate_accessed_dirty() that could trigger a EPT
  misconfiguration VM-exit.
  
  An EPT misconfiguration is triggered when the processor encounters a PTE
  that is writable but not readable (WR=10). On processors that require A/D
  bit emulation PG_M and PG_A map to EPT_PG_WRITE and EPT_PG_READ respectively.
  
  If the PTE is updated as in the following code snippet:
*pte |= PG_M;
*pte |= PG_A;
  then it is possible for another processor to observe the PTE after the PG_M
  (aka EPT_PG_WRITE) bit is set but before PG_A (aka EPT_PG_READ) bit is set.
  
  This will trigger an EPT misconfiguration VM-exit on the other processor.

Sorry, I meant r271635.  (185979 isn't a random number in case you're 
wondering -- it's the mercurial changelog number for r271635 in my

2014-10-20 Thread Craig Rodrigues 
Hi,

Just to add some background to this fix, in the https://jenkins.freebsd.org
cluster,
we are using several bhyve VM's to host the environment for doing builds
and tests.  We are hammering on the VM's
quite nicely.  We found one problem where the bhyve binary would crash.

Neel looked at the problem, and came up with this fix.

Thanks, Neel!
