This will ensure we get a build-time error if the whitelist does not
match the KMI resulting from a build. This indicates that some
whitelisted symbols are not actually exported, or that we export
non-whitelisted symbols. This is non-desirable either way.

As was, chmod would change the cached inode's mode, which would
persist until the inode was uncached.
Fix to change mode of backing file, but make sure mount files
are read only, backing files are always writeable.

s390/mm: fix page table upgrade vs 2ndary address mode accesses
Linux 5.4.36
Signed-off-by: Greg Kroah-Hartman <gregkh@google.com>
Change-Id: Idd8d97e7f00eb7389e184fc4186c4c0dd14f1704
commit 316ec154810960052d4586b634156c54d0778f74 upstream.
A page table upgrade in a kernel section that uses secondary address
mode will mess up the kernel instructions as follows:
Consider the following scenario: two threads are sharing memory.
On CPU1 thread 1 does e.g. strnlen_user(). That gets to
old_fs = enable_sacf_uaccess();
len = strnlen_user_srst(src, size);
and
" la %2,0(%1)\n"
" la %3,0(%0,%1)\n"
" slgr %0,%0\n"
" sacf 256\n"
"0: srst %3,%2\n"
in strnlen_user_srst(). At that point we are in secondary space mode,
control register 1 points to kernel page table and instruction fetching
happens via c1, rather than usual c13. Interrupts are not disabled, for
obvious reasons.
On CPU2 thread 2 does MAP_FIXED mmap(), forcing the upgrade of page table
from 3-level to e.g. 4-level one. We'd allocated new top-level table,
set it up and now we hit this:
notify = 1;
spin_unlock_bh(&mm->page_table_lock);
}
if (notify)
on_each_cpu(__crst_table_upgrade, mm, 0);
OK, we need to actually change over to use of new page table and we
need that to happen in all threads that are currently running. Which
happens to include the thread 1. IPI is delivered and we have
static void __crst_table_upgrade(void *arg)
{
struct mm_struct *mm = arg;
if (current->active_mm == mm)
set_user_asce(mm);
__tlb_flush_local();
}
run on CPU1. That does
static inline void set_user_asce(struct mm_struct *mm)
{
S390_lowcore.user_asce = mm->context.asce;
OK, user page table address updated...
__ctl_load(S390_lowcore.user_asce, 1, 1);
... and control register 1 set to it.
clear_cpu_flag(CIF_ASCE_PRIMARY);
}
IPI is run in home space mode, so it's fine - insns are fetched
using c13, which always points to kernel page table. But as soon
as we return from the interrupt, previous PSW is restored, putting
CPU1 back into secondary space mode, at which point we no longer
get the kernel instructions from the kernel mapping.
The fix is to only fixup the control registers that are currently in use
for user processes during the page table update. We must also disable
interrupts in enable_sacf_uaccess to synchronize the cr and
thread.mm_segment updates against the on_each-cpu.

commit 556d687a4ccd54ab50a721ddde42c820545effd9 upstream.
In order to use compat_* type defininitions in device drivers
outside of CONFIG_COMPAT, move the inclusion of asm-generic/compat.h
ahead of the #ifdef.
All other architectures already do this.

commit feb8e960d780e170e992a70491eec9dd68f4dbf2 upstream.
CONFIG_PPC_KUAP_DEBUG is not selectable because it depends on PPC_32
which doesn't exists.
Fixing it leads to a deadlock due to a vital register getting
clobbered in _switch().
Change dependency to PPC32 and use r0 instead of r4 in _switch()

commit 61da50b76b62fd815aa82d853bf82bf4f69568f5 upstream.
Currently you can enable PPC_KUAP_DEBUG when PPC_KUAP is disabled,
even though the former has not effect without the latter.
Fix it so that PPC_KUAP_DEBUG can only be enabled when PPC_KUAP is
enabled, not when the platform could support KUAP (PPC_HAVE_KUAP).

commit 3dc4db3662366306e54ddcbda4804acb1258e4ba upstream.
For SCIF and HSCIF interfaces the SCxSR register holds the status of
data that is to be read next from SCxRDR register, But where as for
SCIFA and SCIFB interfaces SCxSR register holds status of data that is
previously read from SCxRDR register.
This patch makes sure the status register is read depending on the port
types so that errors are caught accordingly.

commit 8f97250c21f0cf36434bf5b7ddf4377406534cd1 upstream.
The default control endpoint ep0 can return a STALL indicating the
device does not support the control transfer requests. This is called
a protocol stall and does not halt the endpoint.
xHC behaves a bit different. Its internal endpoint state will always
be halted on any stall, even if the device side of the endpiont is not
halted. So we do need to issue the reset endpoint command to clear the
xHC host intenal endpoint halt state, but should not request the HS hub
to clear the TT buffer unless device side of endpoint is halted.
Clearing the hub TT buffer at protocol stall caused ep0 to become
unresponsive for some FS/LS devices behind HS hubs, and class drivers
failed to set the interface due to timeout:
usb 1-2.1: 1:1: usb_set_interface failed (-110)

commit 93ceaa808e8defc67ebca1396e2f42f812a2efc0 upstream.
If a class driver cancels its only URB then the endpoint ring buffer will
appear empty to the xhci driver. xHC hardware may still process cached
TRBs, and complete with a STALL, halting the endpoint.
This halted endpoint was not handled correctly by xhci driver as events on
empty rings were all assumed to be spurious events.
xhci driver refused to restart the ring with EP_HALTED flag set, so class
driver was never informed the endpoint halted even if it queued new URBs.
The host side of the endpoint needs to be reset, and dequeue pointer should
be moved in order to clear the cached TRBs and resetart the endpoint.
Small adjustments in finding the new dequeue pointer are needed to support
the case of stall on an empty ring and unknown current TD.

commit 1c2e54fbf1da5e5445a0ab132c862b02ccd8d230 upstream.
For userspace functions using OS Descriptors, if a function also supplies
Extended Property descriptors currently the counts and lengths stored in
the ms_os_descs_ext_prop_{count,name_len,data_len} variables are not
getting reset to 0 during an unbind or when the epfiles are closed. If
the same function is re-bound and the descriptors are re-written, this
results in those count/length variables to monotonically increase
causing the VLA allocation in _ffs_func_bind() to grow larger and larger
at each bind/unbind cycle and eventually fail to allocate.
Fix this by clearing the ms_os_descs_ext_prop count & lengths to 0 in
ffs_data_reset().

commit 49e0590e3a60e75b493e5df879e216e5073c7663 upstream.
A request may not be completed because not all the TRBs are prepared for
it. This happens when we run out of available TRBs. When some TRBs are
completed, the driver needs to prepare the rest of the TRBs for the
request. The check dwc3_gadget_ep_request_completed() shouldn't be
checking the amount of data received but rather the number of pending
TRBs. Revise this request completion check.
