n_tty: fix EXTPROC vs ICANON interaction with TIOCINQ (aka FIONREAD)
commit
966031f340185eddd05affcf72b740549f056348 upstream.
We added support for EXTPROC back in 2010 in commit
26df6d13406d ("tty:
Add EXTPROC support for LINEMODE") and the intent was to allow it to
override some (all?) ICANON behavior. Quoting from that original commit
message:
There is a new bit in the termios local flag word, EXTPROC.
When this bit is set, several aspects of the terminal driver
are disabled. Input line editing, character echo, and mapping
of signals are all disabled. This allows the telnetd to turn
off these functions when in linemode, but still keep track of
what state the user wants the terminal to be in.
but the problem turns out that "several aspects of the terminal driver
are disabled" is a bit ambiguous, and you can really confuse the n_tty
layer by setting EXTPROC and then causing some of the ICANON invariants
to no longer be maintained.
This fixes at least one such case (TIOCINQ) becoming unhappy because of
the confusion over whether ICANON really means ICANON when EXTPROC is set.
This basically makes TIOCINQ match the case of read: if EXTPROC is set,
we ignore ICANON. Also, make sure to reset the ICANON state ie EXTPROC
changes, not just if ICANON changes.

smpboot_setup_warm_reset_vector() and smpboot_restore_warm_reset_vector()
invoke local_flush_tlb() for no obvious reason.
Digging in history revealed that the original code in the 2.1 era added
those because the code manipulated a swapper_pg_dir pagetable entry. The
pagetable manipulation was removed long ago in the 2.3 timeframe, but the
TLB flush invocations stayed around forever.
Remove them along with the pointless pr_debug()s which come from the same 2.1
change.

nohz: Prevent a timer interrupt storm in tick_nohz_stop_sched_tick()
commit
5d62c183f9e9df1deeea0906d099a94e8a43047a upstream.
The conditions in irq_exit() to invoke tick_nohz_irq_exit() which
subsequently invokes tick_nohz_stop_sched_tick() are:
if ((idle_cpu(cpu) && !need_resched()) || tick_nohz_full_cpu(cpu))
If need_resched() is not set, but a timer softirq is pending then this is
an indication that the softirq code punted and delegated the execution to
softirqd. need_resched() is not true because the current interrupted task
takes precedence over softirqd.
Invoking tick_nohz_irq_exit() in this case can cause an endless loop of
timer interrupts because the timer wheel contains an expired timer, but
softirqs are not yet executed. So it returns an immediate expiry request,
which causes the timer to fire immediately again. Lather, rinse and
repeat....
Prevent that by adding a check for a pending timer soft interrupt to the
conditions in tick_nohz_stop_sched_tick() which avoid calling
get_next_timer_interrupt(). That keeps the tick sched timer on the tick and
prevents a repetitive programming of an already expired timer.

off by one in commit
81cf4a45360f ("USB: core: Add type-specific length

It uses USB_DT_USB_SSP_CAP_SIZE() to get SSP capability size which takes
the zero based SSAC as argument, not the actual count of sublink speed
attributes.
USB3 spec 9.6.2.5 says "The number of Sublink Speed Attributes = SSAC + 1."
The type-specific length check patch was added to stable and needs to be
fixed there as well

Simplify the patch compared to v1 as suggested by Bjørn Mork by taking
advantage of the fact that existing devices work with sendsetup = true
too.
Use sendsetup = true for the NMEA interface of QCSERIAL_SWI and add
DEVICE_SWI entries for the EM7565 PID 0x9091 and the EM7565 QDL PID
0x9090.

net: phy: micrel: ksz9031: reconfigure autoneg after phy autoneg workaround
[ Upstream commit
c1a8d0a3accf64a014d605e6806ce05d1c17adf1 ]
Under some circumstances driver will perform PHY reset in
ksz9031_read_status() to fix autoneg failure case (idle error count =
0xFF). When this happens ksz9031 will not detect link status change any
more when connecting to Netgear 1G switch (link can be recovered sometimes by
restarting netdevice "ifconfig down up"). Reproduced with TI am572x board
equipped with ksz9031 PHY while connecting to Netgear 1G switch.
Fix the issue by reconfiguring autonegotiation after PHY reset in
ksz9031_read_status().

net: Fix double free and memory corruption in get_net_ns_by_id()
[ Upstream commit
21b5944350052d2583e82dd59b19a9ba94a007f0 ]
(I can trivially verify that that idr_remove in cleanup_net happens
after the network namespace count has dropped to zero --EWB)
Function get_net_ns_by_id() does not check for net::count
after it has found a peer in netns_ids idr.
It may dereference a peer, after its count has already been
finaly decremented. This leads to double free and memory
corruption:
put_net(peer) rtnl_lock()
atomic_dec_and_test(&peer->count) [count=0] ...
__put_net(peer) get_net_ns_by_id(net, id)
spin_lock(&cleanup_list_lock)
list_add(&net->cleanup_list, &cleanup_list)
spin_unlock(&cleanup_list_lock)
queue_work() peer = idr_find(&net->netns_ids, id)
| get_net(peer) [count=1]
| ...
| (use after final put)
v ...

idr_remove(&tmp->netns_ids, id) ...
... ...
net_drop_ns() ...
net_free(peer) ...
} ...
|
v
cleanup_net()
...
(Second free of peer)
Also, put_net() on the right cpu may reorder with left's cpu
list_replace_init(&cleanup_list, ..), and then cleanup_list
will be corrupted.
Since cleanup_net() is executed in worker thread, while
put_net(peer) can happen everywhere, there should be
enough time for concurrent get_net_ns_by_id() to pick
the peer up, and the race does not seem to be unlikely.
The patch fixes the problem in standard way.
(Also, there is possible problem in peernet2id_alloc(), which requires
check for net::count under nsid_lock and maybe_get_net(peer), but
in current stable kernel it's used under rtnl_lock() and it has to be
safe. Openswitch begun to use peernet2id_alloc(), and possibly it should
be fixed too. While this is not in stable kernel yet, so I'll send
a separate message to netdev@ later).

net: bridge: fix early call to br_stp_change_bridge_id and plug newlink leaks
[ Upstream commit
84aeb437ab98a2bce3d4b2111c79723aedfceb33 ]
The early call to br_stp_change_bridge_id in bridge's newlink can cause
a memory leak if an error occurs during the newlink because the fdb
entries are not cleaned up if a different lladdr was specified, also
another minor issue is that it generates fdb notifications with
ifindex = 0. Another unrelated memory leak is the bridge sysfs entries
which get added on NETDEV_REGISTER event, but are not cleaned up in the
newlink error path. To remove this special case the call to
br_stp_change_bridge_id is done after netdev register and we cleanup the
bridge on changelink error via br_dev_delete to plug all leaks.
This patch makes netlink bridge destruction on newlink error the same as
dellink and ioctl del which is necessary since at that point we have a
fully initialized bridge device.
To reproduce the issue:
$ ip l add br0 address 00:11:22:33:44:55 type bridge group_fwd_mask 1
RTNETLINK answers: Invalid argument
$ rmmod bridge

ipv4: Fix use-after-free when flushing FIB tables
[ Upstream commit

Since commit
0ddcf43d5d4a ("ipv4: FIB Local/MAIN table collapse") the
local table uses the same trie allocated for the main table when custom
rules are not in use.
When a net namespace is dismantled, the main table is flushed and freed
(via an RCU callback) before the local table. In case the callback is
invoked before the local table is iterated, a use-after-free can occur.
Fix this by iterating over the FIB tables in reverse order, so that the
main table is always freed after the local table.
v3: Reworded comment according to Alex's suggestion.
v2: Add a comment to make the fix more explicit per Dave's and Alex's
feedback.

tcp md5sig: Use skb's saddr when replying to an incoming segment
[ Upstream commit
30791ac41927ebd3e75486f9504b6d2280463bf0 ]
The MD5-key that belongs to a connection is identified by the peer's
IP-address. When we are in tcp_v4(6)_reqsk_send_ack(), we are replying
to an incoming segment from tcp_check_req() that failed the seq-number
checks.
Thus, to find the correct key, we need to use the skb's saddr and not
the daddr.
This bug seems to have been there since quite a while, but probably got
unnoticed because the consequences are not catastrophic. We will call
tcp_v4_reqsk_send_ack only to send a challenge-ACK back to the peer,
thus the connection doesn't really fail.

net: reevalulate autoflowlabel setting after sysctl setting
[ Upstream commit
513674b5a2c9c7a67501506419da5c3c77ac6f08 ]
sysctl.ip6.auto_flowlabels is default 1. In our hosts, we set it to 2.
If sockopt doesn't set autoflowlabel, outcome packets from the hosts are
supposed to not include flowlabel. This is true for normal packet, but
not for reset packet.
The reason is ipv6_pinfo.autoflowlabel is set in sock creation. Later if
we change sysctl.ip6.auto_flowlabels, the ipv6_pinfo.autoflowlabel isn't
changed, so the sock will keep the old behavior in terms of auto
flowlabel. Reset packet is suffering from this problem, because reset
packet is sent from a special control socket, which is created at boot
time. Since sysctl.ipv6.auto_flowlabels is 1 by default, the control
socket will always have its ipv6_pinfo.autoflowlabel set, even after
user set sysctl.ipv6.auto_flowlabels to 1, so reset packset will always
have flowlabel. Normal sock created before sysctl setting suffers from
the same issue. We can't even turn off autoflowlabel unless we kill all
socks in the hosts.
To fix this, if IPV6_AUTOFLOWLABEL sockopt is used, we use the
autoflowlabel setting from user, otherwise we always call
ip6_default_np_autolabel() which has the new settings of sysctl.
Note, this changes behavior a little bit. Before commit
42240901f7c4
(ipv6: Implement different admin modes for automatic flow labels), the
autoflowlabel behavior of a sock isn't sticky, eg, if sysctl changes,
existing connection will change autoflowlabel behavior. After that
commit, autoflowlabel behavior is sticky in the whole life of the sock.
With this patch, the behavior isn't sticky again.

IPv6 stack reacts to changes to small MTU, by disabling itself under

But there is a window where threads not using RTNL can see a wrong

the mtu is suitable.
Fix this by reading device mtu once and checking IPv6 minimal MTU.

ipv4: igmp: guard against silly MTU values
[ Upstream commit
b5476022bbada3764609368f03329ca287528dc8 ]
IPv4 stack reacts to changes to small MTU, by disabling itself under
RTNL.
But there is a window where threads not using RTNL can see a wrong
device mtu. This can lead to surprises, in igmp code where it is
assumed the mtu is suitable.
Fix this by reading device mtu once and checking IPv4 minimal MTU.
This patch adds missing IPV4_MIN_MTU define, to not abuse
ETH_MIN_MTU anymore.

kbuild: add '-fno-stack-check' to kernel build options
commit

It appears that hardened gentoo enables "-fstack-check" by default for
gcc.
That doesn't work _at_all_ for the kernel, because the kernel stack
doesn't act like a user stack at all: it's much smaller, and it doesn't
auto-expand on use. So the extra "probe one page below the stack" code
generated by -fstack-check just breaks the kernel in horrible ways,
causing infinite double faults etc.
[ I have to say, that the particular code gcc generates looks very
stupid even for user space where it works, but that's a separate
issue. ]

Trying to reboot via real mode fails with PCID on: long mode cannot

SDM and actual CPUs are in agreement here.) The result is a GPF and
a hang instead of a reboot.

x86/mm: Remove the UP asm/tlbflush.h code, always use the (formerly) SMP code
commit
ce4a4e565f5264909a18c733b864c3f74467f69e upstream.
The UP asm/tlbflush.h generates somewhat nicer code than the SMP version.
Aside from that, it's fallen quite a bit behind the SMP code:
- flush_tlb_mm_range() didn't flush individual pages if the range
was small.
- The lazy TLB code was much weaker. This usually wouldn't matter,
but, if a kernel thread flushed its lazy "active_mm" more than
once (due to reclaim or similar), it wouldn't be unlazied and
would instead pointlessly flush repeatedly.
- Tracepoints were missing.
Aside from that, simply having the UP code around was a maintanence
burden, since it means that any change to the TLB flush code had to
make sure not to break it.
Simplify everything by deleting the UP code.

x86/mm: Reimplement flush_tlb_page() using flush_tlb_mm_range()
commit
ca6c99c0794875c6d1db6e22f246699691ab7e6b upstream.
flush_tlb_page() was very similar to flush_tlb_mm_range() except that
it had a couple of issues:
- It was missing an smp_mb() in the case where
current->active_mm != mm. (This is a longstanding bug reported by Nadav Amit)
- It was missing tracepoints and vm counter updates.
The only reason that I can see for keeping it at as a separate
function is that it could avoid a few branches that
flush_tlb_mm_range() needs to decide to flush just one page. This
hardly seems worthwhile. If we decide we want to get rid of those
branches again, a better way would be to introduce an
__flush_tlb_mm_range() helper and make both flush_tlb_page() and
flush_tlb_mm_range() use it.

x86/mm: Make flush_tlb_mm_range() more predictable
commit
ce27374fabf553153c3f53efcaa9bfab9216bd8c upstream.
I'm about to rewrite the function almost completely, but first I
want to get a functional change out of the way. Currently, if
flush_tlb_mm_range() does not flush the local TLB at all, it will
never do individual page flushes on remote CPUs. This seems to be
an accident, and preserving it will be awkward. Let's change it
first so that any regressions in the rewrite will be easier to
bisect and so that the rewrite can attempt to change no visible
behavior at all.
The fix is simple: we can simply avoid short-circuiting the
calculation of base_pages_to_flush.
As a side effect, this also eliminates a potential corner case: if
tlb_single_page_flush_ceiling == TLB_FLUSH_ALL, flush_tlb_mm_range()
could have ended up flushing the entire address space one page at a
time.

ring-buffer: Mask out the info bits when returning buffer page length
commit

Two info bits were added to the "commit" part of the ring buffer data page
when returned to be consumed. This was to inform the user space readers that
events have been missed, and that the count may be stored at the end of the
page.
What wasn't handled, was the splice code that actually called a function to
return the length of the data in order to zero out the rest of the page
before sending it up to user space. These data bits were returned with the
length making the value negative, and that negative value was not checked.
It was compared to PAGE_SIZE, and only used if the size was less than
PAGE_SIZE. Luckily PAGE_SIZE is unsigned long which made the compare an
unsigned compare, meaning the negative size value did not end up causing a
large portion of memory to be randomly zeroed out.

Double free of the ring buffer happens when it fails to alloc new

spi: xilinx: Detect stall with Unknown commands
commit
5a1314fa697fc65cefaba64cd4699bfc3e6882a6 upstream.
When the core is configured in C_SPI_MODE > 0, it integrates a
lookup table that automatically configures the core in dual or quad mode
based on the command (first byte on the tx fifo).
Unfortunately, that list mode_?_memoy_*.mif does not contain all the
supported commands by the flash.
Since 4.14 spi-nor automatically tries to probe the flash using SFDP
(command 0x5a), and that command is not part of the list_mode table.
Whit the right combination of C_SPI_MODE and C_SPI_MEMORY this leads
into a stall that can only be recovered with a soft rest.
This patch detects this kind of stall and returns -EIO to the caller on
those commands. spi-nor can handle this error properly:
m25p80 spi0.0: Detected stall. Check C_SPI_MODE and C_SPI_MEMORY. 0x21 0x2404

It is incorrect to call pci_restore_state() for devices in low-power
states (D1-D3), as that involves the restoration of MSI setup which
requires MMIO to be operational and that is only the case in D0.
However, pci_pm_thaw_noirq() may do that if the driver's "freeze"
callbacks put the device into a low-power state, so fix it by making
it force devices into D0 via pci_set_power_state() instead of trying
to "update" their power state which is pointless.

ALSA: usb-audio: Fix the missing ctl name suffix at parsing SU
commit
5a15f289ee87eaf33f13f08a4909ec99d837ec5f upstream.
The commit
89b89d121ffc ("ALSA: usb-audio: Add check return value for
usb_string()") added the check of the return value from
snd_usb_copy_string_desc(), which is correct per se, but it introduced
a regression. In the original code, either the "Clock Source",
"Playback Source" or "Capture Source" suffix is added after the
terminal string, while the commit changed it to add the suffix only
when get_term_name() is failing. It ended up with an incorrect ctl
name like "PCM" instead of "PCM Capture Source".
Also, even the original code has a similar bug: when the ctl name is
generated from snd_usb_copy_string_desc() for the given iSelector, it
also doesn't put the suffix.
This patch addresses these issues: the suffix is added always when no
static mapping is found. Also the patch tries to put more comments
and cleans up the if/else block for better readability in order to
avoid the same pitfall again.

ALSA: rawmidi: Avoid racy info ioctl via ctl device
commit
c1cfd9025cc394fd137a01159d74335c5ac978ce upstream.
The rawmidi also allows to obtaining the information via ioctl of ctl
API. It means that user can issue an ioctl to the rawmidi device even
when it's being removed as long as the control device is present.
Although the code has some protection via the global register_mutex,
its range is limited to the search of the corresponding rawmidi
object, and the mutex is already unlocked at accessing the rawmidi
object. This may lead to a use-after-free.
For avoiding it, this patch widens the application of register_mutex
to the whole snd_rawmidi_info_select() function. We have another
mutex per rawmidi object, but this operation isn't very hot path, so
it shouldn't matter from the performance POV.

mfd: cros ec: spi: Don't send first message too soon
commit
15d8374874ded0bec37ef27f8301a6d54032c0e5 upstream.
On the Tegra124 Nyan-Big chromebook the very first SPI message sent to
the EC is failing.
The Tegra SPI driver configures the SPI chip-selects to be active-high
by default (and always has for many years). The EC SPI requires an
active-low chip-select and so the Tegra chip-select is reconfigured to
be active-low when the EC SPI driver calls spi_setup(). The problem is
that if the first SPI message to the EC is sent too soon after
reconfiguring the SPI chip-select, it fails.
The EC SPI driver prevents back-to-back SPI messages being sent too
soon by keeping track of the time the last transfer was sent via the
variable 'last_transfer_ns'. To prevent the very first transfer being
sent too soon, initialise the 'last_transfer_ns' variable after calling
spi_setup() and before sending the first SPI message.

crypto: mcryptd - protect the per-CPU queue with a lock
commit
9abffc6f2efe46c3564c04312e52e07622d40e51 upstream.
mcryptd_enqueue_request() grabs the per-CPU queue struct and protects
access to it with disabled preemption. Then it schedules a worker on the
same CPU. The worker in mcryptd_queue_worker() guards access to the same
per-CPU variable with disabled preemption.
If we take CPU-hotplug into account then it is possible that between
queue_work_on() and the actual invocation of the worker the CPU goes
down and the worker will be scheduled on _another_ CPU. And here the
preempt_disable() protection does not work anymore. The easiest thing is
to add a spin_lock() to guard access to the list.
Another detail: mcryptd_queue_worker() is not processing more than
MCRYPTD_BATCH invocation in a row. If there are still items left, then
it will invoke queue_work() to proceed with more later. *I* would
suggest to simply drop that check because it does not use a system
workqueue and the workqueue is already marked as "CPU_INTENSIVE". And if
preemption is required then the scheduler should do it.
However if queue_work() is used then the work item is marked as CPU
unbound. That means it will try to run on the local CPU but it may run
on another CPU as well. Especially with CONFIG_DEBUG_WQ_FORCE_RR_CPU=y.
Again, the preempt_disable() won't work here but lock which was
introduced will help.
In order to keep work-item on the local CPU (and avoid RR) I changed it
to queue_work_on().

ACPI: APEI / ERST: Fix missing error handling in erst_reader()
commit
bb82e0b4a7e96494f0c1004ce50cec3d7b5fb3d1 upstream.
The commit
f6f828513290 ("pstore: pass allocated memory region back to
caller") changed the check of the return value from erst_read() in
erst_reader() in the following way:
if (len == -ENOENT)
goto skip;
- else if (len < 0) {
- rc = -1;
+ else if (len < sizeof(*rcd)) {
+ rc = -EIO;
goto out;
This introduced another bug: since the comparison with sizeof() is
cast to unsigned, a negative len value doesn't hit any longer.
As a result, when an error is returned from erst_read(), the code
falls through, and it may eventually lead to some weird thing like
memory corruption.
This patch adds the negative error value check more explicitly for
addressing the issue.

The hdac_acomp object in hdac_i915.c is left as assigned even after

ALSA: hda - Degrade i915 binding failure message
commit
bed2e98e1f4db8b827df507abc30be7b11b0613d upstream.
Currently HD-audio driver on Intel Skylake or Broxteon gives an error
message when binding with i915 audio component fails. However, this
isn't any serious error on a system without Intel graphics. Indeed
there are such systems, where a third-party codec (e.g. Creative) is
put on the mobo while using other discrete GPU (e.g. Nvidia).
Printing a kernel "error" message is overreaction in such a case.
This patch downgrades the print level for that message. For systems
that mandate the i915 binding (e.g. Haswell or Broadwell HDMI/DP),
another kernel error message is shown in addition to make clear what
went wrong.

The commit [
d745f5e7b8b2: ALSA: hda - Add the pin / port mapping on
Intel ILK and VLV] introduced a WARN_ON() to check the pointer for
avoiding the double initializations. But hdac_acomp pointer wasn't
cleared at snd_hdac_i915_exit(), thus after reloading the HD-audio
driver, it may result in the false positive warning. This patch makes
sure to clear the leftover pointer at exit.

MIPS: math-emu: Fix final emulation phase for certain instructions
commit
409fcace9963c1e8d2cb0f7ac62e8b34d47ef979 upstream.
Fix final phase of <CLASS|MADDF|MSUBF|MAX|MIN|MAXA|MINA>.<D|S>
emulation. Provide proper generation of SIGFPE signal and updating
debugfs FP exception stats in cases of any exception flags set in
preceding phases of emulation.
CLASS.<D|S> instruction may generate "Unimplemented Operation" FP
exception. <MADDF|MSUBF>.<D|S> instructions may generate "Inexact",
"Unimplemented Operation", "Invalid Operation", "Overflow", and
"Underflow" FP exceptions. <MAX|MIN|MAXA|MINA>.<D|S> instructions
can generate "Unimplemented Operation" and "Invalid Operation" FP
exceptions.
The proper final processing of the cases when any FP exception
flag is set is achieved by replacing "break" statement with "goto
copcsr" statement. With such solution, this patch brings the final
phase of emulation of the above instructions consistent with the
one corresponding to the previously implemented emulation of other
related FPU instructions (ADD, SUB, etc.).

cpuidle: fix broadcast control when broadcast can not be entered
[ Upstream commit
f187851b9b4a76952b1158b86434563dd2031103 ]
When failing to enter broadcast timer mode for an idle state that
requires it, a new state is selected that does not require broadcast,
but the broadcast variable remains set. This causes
tick_broadcast_exit to be called despite not having entered broadcast
mode.
This causes the WARN_ON_ONCE(!irqs_disabled()) to trigger in some
cases. It does not appear to cause problems for code today, but seems
to violate the interface so should be fixed.

[ Upstream commit

When we process VF mailboxes, the driver is likely going to also queue
up messages to the switch manager. This process merely queues up the
FIFO, but doesn't actually begin the transmission process. Because we
hold the mailbox lock during this VF processing, the PF<->SM mailbox is
not getting processed at this time. Ensure that we actually process the
PF<->SM mailbox in between each PF<->VF mailbox.
This should ensure prompt transmission of the messages queued up after
each VF message is received and handled.

PCI/AER: Report non-fatal errors only to the affected endpoint
[ Upstream commit
86acc790717fb60fb51ea3095084e331d8711c74 ]
Previously, if an non-fatal error was reported by an endpoint, we
called report_error_detected() for the endpoint, every sibling on the
bus, and their descendents. If any of them did not implement the
.error_detected() method, do_recovery() failed, leaving all these
devices unrecovered.
For example, the system described in the bugzilla below has two devices:
0000:74:02.0 [19e5:a230] SAS controller, driver has .error_detected()
0000:74:03.0 [19e5:a235] SATA controller, driver lacks .error_detected()
When a device such as 74:02.0 reported a non-fatal error, do_recovery()
failed because 74:03.0 lacked an .error_detected() method. But per PCIe
r3.1, sec 6.2.2.2.2, such an error does not compromise the Link and
does not affect 74:03.0:
Non-fatal errors are uncorrectable errors which cause a particular
transaction to be unreliable but the Link is otherwise fully functional.
Isolating Non-fatal from Fatal errors provides Requester/Receiver logic
in a device or system management software the opportunity to recover from
the error without resetting the components on the Link and disturbing
other transactions in progress. Devices not associated with the
transaction in error are not impacted by the error.
Report non-fatal errors only to the endpoint that reported them. We really
want to check for AER_NONFATAL here, but the current code structure doesn't
allow that. Looking for pci_channel_io_normal is the best we can do now.

When checking to see if a PCI bus can safely be reset, we previously
checked to see if any of the children had their PCI_DEV_FLAGS_NO_BUS_RESET
flag set. Children marked with that flag are known not to behave well
after a bus reset.
Some PCIe root port bridges also do not behave well after a bus reset,
sometimes causing the devices behind the bridge to become unusable.
Add a check for PCI_DEV_FLAGS_NO_BUS_RESET being set in the bridge device
to allow these bridges to be flagged, and prevent their secondary buses
from being reset.
