If user does forced unmount ("umount -f") while files are still open
on the share (as was seen in a Kubernetes example running on SMB3.1.1
mount) then we were marking the share as "TID_EXITING" in umount_begin()
which caused all subsequent operations (except write) to fail ... but
unfortunately when umount_begin() is called we do not know yet that
there are open files or active references on the share that would prevent
unmount from succeeding. Kubernetes had example when they were doing
umount -f when files were open which caused the share to become
unusable until the files were closed (and the umount retried).
Fix this so that TID_EXITING is not set until we are about to send
the tree disconnect (not at the beginning of forced umounts in
umount_begin) so that if "umount -f" fails (due to open files or
references) the mount is still usable.

Get rid of any prefix paths in @path before lookup_positive_unlocked()
as it will call ->lookup() which already adds those prefix paths
through build_path_from_dentry().
This has caused a performance regression when mounting shares with a
prefix path where readdir(2) would end up retrying several times to
open bad directory names that contained duplicate prefix paths.
Fix this by skipping any prefix paths in @path before calling
lookup_positive_unlocked().

Performance tests with large number of threads noted that the change
of the default closetimeo (deferred close timeout between when
close is done by application and when client has to send the close
to the server), to 5 seconds from 1 second, significantly degraded
perf in some cases like this (in the filebench example reported,
the stats show close requests on the wire taking twice as long,
and 50% regression in filebench perf). This is stil configurable
via mount parm closetimeo, but to be safe, decrease default back
to its previous value of 1 second.

The setup_load_info() was actually had ELF validation checks of its
own. To later cache useful variables as an secondary step just means
looping again over the ELF sections we just validated. We can simply
keep tabs of the key sections of interest as we validate the module

together.

The integrity of the struct module we load is important, and although
our ELF validator already checks that the module section must match
struct module, add a stop-gap check before we memcpy() the final minted
module. This also makes those inspecting the code what the goal is.
While at it, clarify the goal behind updating the sh_addr address.
The current comment is pretty misleading.
Signed-off-by: Luis Chamberlain <mcgrof@kernel.org>
The ELF ".gnu.linkonce.this_module" section is special, it is what we
use to construct the struct module __this_module, which THIS_MODULE
points to. When userspace loads a module we always deal first with a
copy of the userspace buffer, and twiddle with the userspace copy's
version of the struct module. Eventually we allocate memory to do a
memcpy() of that struct module, under the assumption that the module
size is right. But we have no validity checks against the size or
the requirements for the section.
Add some validity checks for the special module section early and while
at it, cache the module section index early, so we don't have to do that
later.
While at it, just move over the assigment of the info->mod to make the
code clearer. The validity checker also adds an explicit size check to
ensure the module section size matches the kernel's run time size for
sizeof(struct module). This should prevent sloppy loads of modules
which are built today *without* actually increasing the size of
the struct module. A developer today can for example expand the size
of struct module, rebuild a directoroy 'make fs/xfs/' for example and
then try to insmode the driver there. That module would in effect have
an incorrect size. This new size check would put a stop gap against such
mistakes.
This also makes the entire goal of ".gnu.linkonce.this_module" pretty
clear. Before this patch verification of the goal / intent required some
Indian Jones whips, torches and cleaning up big old spider webs.

check_modinfo() actually does two things:
a) sanity checks, some of which are fatal, and so we
prevent the user from completing trying to load a module
b) taints the kernel
The taints are pretty heavy handed because we're tainting the kernel
*before* we ever even get to load the module into the modules linked
list. That is, it it can fail for other reasons later as we review the
module's structure.

clearer and splits the code up where needed to make that happen.

third version part 2, functionally I had to move from spin_lock to
spin_lock_irqsave because of an interrupt that was calling start_xmit,
see attached stack. This is tested on tcan455x but I don't have the
integrated hardware myself so any testing is appreciated.
The series implements many small and bigger throughput improvements.
Changes in v3:
- Remove parenthesis in error messages
- Use memcpy_and_pad for buffer copy in 'can: m_can: Write transmit
header and data in one transaction'.
- Replace spin_lock with spin_lock_irqsave. I got a report of a
interrupt that was calling start_xmit just after the netqueue was
woken up before the locked region was exited. spin_lock_irqsave should
fix this. I attached the full stack at the end of the mail if someone
wants to know.
- Rebased to v6.3-rc1.
- Removed tcan4x5x patches from this series.

Interrupts currently get disabled if the interrupt status shows new
received data. Non-peripheral chips handle receiving in a worker thread,
but peripheral chips are handling the receive process in the threaded
interrupt routine itself without scheduling it for a different worker.
So there is no need to disable interrupts for peripheral chips.

Add support for CAN transceivers described as PHYs.
While simple CAN transceivers can do without, this is needed for CAN
transceivers like NXP TJR1443 that need a configuration step (like
pulling standby or enable lines), and/or impose a bitrate limit.

Add a for_each_modinfo_entry() to make it easier to read and use.
This produces no functional changes but makes this code easiert
to read as we are used to with loops in the kernel and trims more
lines of code.

This makes it clearer what it is doing. While at it,
make it available to other code other than main.c.
This will be used in the subsequent patch and make
the changes easier to read.

Instead of forward declaring routines for get_modinfo() just move
everything up. This makes no functional changes.

Commit 312b62b661 ("ARM: mstar: Add machine for MStar/Sigmastar Armv7
SoCs") adds the config MACH_INFINITY and MACH_MERCURY. The MACH_INFINITY
config is used in the gpio-msc313 driver, but the MACH_MERCURY config is
never used to configure anything in the kernel tree.
Remove the unused config MACH_MERCURY.

Modern versions of FVP_Base_RevC-2xAEMvA contain a Virtio RNG device,
use of which can dramatically speed up the time taken for Linux to
initialize its CRNG, from 10s of seconds in some cases, to instant. This
improves the debug cycle significantly.
However, there are 2 barriers to getting people to use it. The first is
that the defconfig doesn't have the required driver. The second is that
the device is disabled in the device tree (for back-compat since older
versions of the FVP don't have the device). Here we solve the first
issue.
