8600ba1aa9 Make sure the selrecord() function is only called from within system
polling contexts in the LinuxKPI.

After the kqueue() support was added to the LinuxKPI in r319409 the
Linux poll file operation will be used outside the system file polling
callback function, which can cause a NULL-pointer panic inside
selrecord() because curthread->td_sel is set to NULL. This patch moves
the selrecord() call away from poll_wait() and to the system file poll
callback function in the LinuxKPI, which essentially wraps the Linux
one. This is similar to what the cuse(3) module is currently doing.
Refer to sys/fs/cuse/*.[ch] for more details.

SRIOV/eSwitch configuration or when the device is in selftest. This

a6b28ee02a Add generic kqueue() and kevent() support to the LinuxKPI character
devices. The implementation allows read and write filters to be
created and piggybacks on the poll() file operation to determine when
a filter should trigger. The piggyback mechanism is simply to check
for the EWOULDBLOCK or EAGAIN return code from read(), write() or
ioctl() system calls and then update the kqueue() polling state bits.
The implementation is similar to the one found in the cuse(3) module.

ea67550be0 Fix a reference count leak in the LinuxKPI due to calling VM open when
it shouldn't be called.

Background:
The Linux VM open operation is called when a new VMA is
created on top of the current VMA. This is done through either mremap
flow or split_vma, usually due to mlock, madvise, munmap and so
on. This is currently not supported by the LinuxKPI.

f5a9867b7d Fixes for refcounting "struct linux_file" in the LinuxKPI.
- Allow "struct linux_file" to be refcounted when its "_file" member
  is NULL by using its "f_count" field. The reference counts are
  transferred to the file structure when the file descriptor is
  installed.

- Add missing vdrop() calls for error cases during open().

- Set the "_file" member of "struct linux_file" during open. This
allows use of refcounting through get_file() and fput() with LinuxKPI
character devices.

bd1c3bad76 add a rescue/sh sanity check before installworld on the running system
FreeBSD does not guarantee kernel forward compatibility (that is,
running a newer userland on an older kernel).  The documented upgrade
procedure specifies that installkernel should be performed, followed by
a reboot and then installworld.  As a sanity check when installing onto
the running system (DESTDIR is / or unset), attempt to run "sh echo OK"
using rescue from the objdir.  If rescue fails (e.g., because the system
has not been rebooted and the "old" kernel lacks a system call required
by the to-be-installed world), abort the installation.

This should avoid ino64 foot-shooting when the proper upgrade procedure
is not followed.

8b07e00e99 Fix an unnecessary/incorrect check in the PKTOPT_EXTHDRCPY macro.
This macro allocates memory and, if malloc does not return NULL, copies
data into the new memory. However, it doesn't just check whether malloc
returns NULL. It also checks whether we called malloc with M_NOWAIT. That
is not necessary.

While it may be that malloc() will only return NULL when the M_NOWAIT flag
is set, we don't need to check for this when checking malloc's return
value. Further, in this case, the check was not completely accurate,
because it checked for flags == M_NOWAIT, rather than treating it as a bit
field and checking for (flags & M_NOWAIT).

fb04394554 Fix two places in the ICMP6 code where we could dereference a NULL pointer
in the icmp6_input() function.

When processing an ICMP6_ECHO_REQUEST, if IP6_EXTHDR_GET fails, it will
set nicmp6 and n to NULL. Therefore, we should condition our modification
to nicmp6 on n being not NULL.

And, when processing an ICMP6_WRUREQUEST in the (mode != FQDN) case, if
m_dup_pkthdr() fails, the code will set n to NULL. However, the very next
line dereferences n. Therefore, when m_dup_pkthdr() fails, we should
discontinue further processing and follow the same path as when m_gethdr()
fails.
