43983eb202 Fix spl-kmod builds when using rpm >= 4.14
With rpm-software-management/rpm@5e94633 a package version containing
invalid characters (most commonly a double '-') causes the kmod package
generation to terminate with an error.  This change takes advantage of
the newly introduced rpm macro "_wrong_version_format_terminate_build"
to allow kmod packages to be built.

Linux 4.14 compat: vfs_read & vfs_write
The kernel_read & kernel_write functions have always wrapped the
vfs_read & vfs_write functions respectively.  However, they could
not be used by vn_rdwr() since the offset wasn't passed as a
pointer.  This prevented us from being able to properly update
the file offset.

Linux 4.14 unexported vfs_read & vfs_write but also changed the
signature of kernel_read & kernel_write to provide the needed
functionality.  Use these updated functions when available.

cce83ba0ec Fix use-after-free in taskq_seq_show_impl
taskq_seq_show_impl walks the tq_active_list to show the tqent_func and
tqent_arg. However for taskq_dispatch_ent, it's very likely that the
task entry will be freed during the function call, and causes a
use-after-free bug.

To fix this, we duplicate the task entry to an on-stack struct, and
assign it instead to tqt_task. This way, the tq_lock alone will
guarantee its safety.

cd47801828 Avoid WARN() from procfs on kstat collision
When we load a ZFS pool having spa_name equals to some existing kstat
we would have to create a duplicate entry, which procfs doesn't like.

For instance a ZFS pool named "zil" would have its kstat "txgs"
(module "zfs/zil") intalled under "/proc/spl/kstat/zfs/zil":
unfortunately we already have a kstat named "zil" (module "zfs")
installed in the same procfs location.

Avoid this issue by skipping the duplicate entry creation in procfs.

c93d9dff36 Don't cache the system hostid
Historically the SPL cached the system hostid the first time it
was accessed.  This was done to speed up subsequent accesses.
But in practice the system host id is rarely accessed and its
inconvenient that it doesn't promptly detect /etc/hostid
configuration changes.  Therefore, zone_get_hostid() has been
updated to always refresh the system hostid reported.

bf8abea4da Linux 4.11 compat: remove stub for __put_task_struct
Before kernel 2.6.29 credentials were embedded in task_structs, and zfs had
cases where one thread would need to refer to the credential of another thread,
forcing it to take a hold on the foreign thread's task_struct to ensure it was
not freed.

Since 2.6.29, the credential has been moved out of the task_struct into a
cred_t.

In addition, the mainline kernel originally did not export __put_task_struct()
but the RHEL5 kernel did, according to zfsonlinux/spl@e811949a57.  As of
2.6.39 the mainline kernel exports it.

There is no longer zfs code that takes or releases holds on a task_struct, and
so there is no longer any reference to __put_task_struct().

This affects the linux 4.11 kernel because the prototype for
__put_task_struct() is in a new include file (linux/sched/task.h) and so the
config check failed to detect the exported symbol.

Removing the unnecessary stub and corresponding config check.  This works on
kernels since the oldest one currently supported, 2.6.32 as shipped with
Centos/RHEL.

9a054d54fb Linux 4.11 compat: add linux/sched/signal.h
In Linux 4.11, torvalds/linux@2a1f062, signal handling related functions
were moved from sched.h into sched/signal.h.

Add configure checks to detect this and include the new file where
needed.

94b1ab2ae0 Linux 4.11 compat: vfs_getattr() takes 4 args
There are changes to vfs_getattr() in torvalds/linux@a528d35.  The new
interface is:

int vfs_getattr(const struct path *path, struct kstat *stat,
               u32 request_mask, unsigned int query_flags)

The request_mask argument indicates which field(s) the caller intends to
use.  Fields the caller does not specify via request_mask may be set in
the returned struct anyway, but their values may be approximate.

The query_flags argument indicates whether the filesystem must update
the attributes from the backing store.

This patch uses the query_flags which result in vfs_getattr behaving the same
as it did with the 2-argument version which the kernel provided before
Linux 4.11.

Members blksize and blocks are now always the same size regardless of
arch.  They match the size of the equivalent members in vnode_t.

The configure checks are modified to ensure that the appropriate
vfs_getattr() interface is used.

A more complete fix, removing the ZFS dependency on vfs_getattr()
entirely, is deferred as it is a much larger project.

e0aacd9b97 Fix powerpc build
Unlike other architectures which sanitize the LDFLAGS from the
environment in arch/<arch>/Makefile.  The powerpc Makefile
allows LDFLAGS to be passed through resulting in the following
build failure.

  /usr/bin/ld: unrecognized option '-Wl,-z,relro'

LDFLAGS is set in /usr/lib/rpm/redhat/macros by default.  Clear
the environment variable when building kmods for powerpc.
