bnxt_en: Bug fixes

This series includes 3 fixes.  The first one fixes a race condition
between devlink reload and SR-IOV configuration.  The second one
fixes a type mismatch warning in devlink fw live patching.  The
last one fixes unwanted OVS TC dmesg error logs when tc-hw-offload is
disabled on bnxt_en.
====================

The driver does not check if hw-tc-offload is enabled for the device
before offloading a flow in the context of indirect block callback.
Fix this by checking NETIF_F_HW_TC in the features flag and rejecting
the offload request.  This will avoid unnecessary dmesg error logs when
hw-tc-offload is disabled, such as these:

The fixes the race condition between configuring SR-IOV and devlink

setting sriov_cfg under the lock while changes are underway. Extend
the lock scope in devlink driver_reinit to cover the VF check and
don't run concurrently with SR-IOV configure.

This bug report shows up when running our research tools. The
reports is SOOB read, but it seems SOOB write is also possible
a few lines below.

In details, fw.len and sw.len are inputs coming from io. A len
over the size of self->rpc triggers SOOB. The patch fixes the
bugs by adding sanity checks.

The bugs are triggerable with compromised/malfunctioning devices.
They are potentially exploitable given they first leak up to
0xffff bytes and able to overwrite the region later.

The patch is tested with QEMU emulater.
This is NOT tested with a real device.

Attached is the log we found by fuzzing.

The SMC fallback is incomplete currently. There may be some
wait queue entries remaining in smc socket->wq, which should
be removed to clcsocket->wq during the fallback.

For example, in nginx/wrk benchmark, this issue causes an
all-zeros test result:

server: nginx -g 'daemon off;'
client: smc_run wrk -c 1 -t 1 -d 5 http://11.200.15.93/index.html

  Running 5s test @ http://11.200.15.93/index.html
     1 threads and 1 connections
     Thread Stats   Avg      Stdev     Max   ± Stdev
     	Latency     0.00us    0.00us   0.00us    -nan%
	Req/Sec     0.00      0.00     0.00      -nan%
	0 requests in 5.00s, 0.00B read
     Requests/sec:      0.00
     Transfer/sec:       0.00B

The reason for this all-zeros result is that when wrk used SMC
to replace TCP, it added an eppoll_entry into smc socket->wq
and expected to be notified if epoll events like EPOLL_IN/
EPOLL_OUT occurred on the smc socket.

However, once a fallback occurred, wrk switches to use clcsocket.
Now it is clcsocket->wq instead of smc socket->wq which will
be woken up. The eppoll_entry remaining in smc socket->wq does
not work anymore and wrk stops the test.

This patch fixes this issue by removing remaining wait queue
entries from smc socket->wq to clcsocket->wq during the fallback.

net: ipa: HOLB register write fixes

This small series fixes two recently identified bugs related to the
way two registers must be written.  The registers define whether and
when to drop packets if a head-of-line blocking condition is
encountered.  The "enable" (dropping packets) register must be
written twice for newer versions of hardware.  And the timer
register must not be written while dropping is enabled.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

The head-of-line blocking timer should only be modified when
head-of-line drop is disabled.

One of the steps in recovering from a modem crash is to enable
dropping of packets with timeout of 0 (immediate).  We don't know
how the modem configured its endpoints, so before we program the
timer, we need to ensure HOL_BLOCK is disabled.

Some functions, like tipc_crypto_start use inconsisten GFP flags
when allocating memory. The mentioned function use GFP_ATOMIC to
to alloc a crypto instance, and then calls alloc_ordered_workqueue()
which allocates memory with GFP_KERNEL. tipc_aead_init() function
even uses GFP_KERNEL and GFP_ATOMIC interchangeably.
No doc comment specifies what context a function is designed to
work in, but the flags should at least be consistent within a function.

This patch reverts two prior patches, e7310c94
("security: implement sctp_assoc_established hook in selinux") and
7c2ef024 ("security: add sctp_assoc_established hook"), which
create the security_sctp_assoc_established() LSM hook and provide a
SELinux implementation.  Unfortunately these two patches were merged
without proper review (the Reviewed-by and Tested-by tags from
Richard Haines were for previous revisions of these patches that
were significantly different) and there are outstanding objections
from the SELinux maintainers regarding these patches.

Work is currently ongoing to correct the problems identified in the
reverted patches, as well as others that have come up during review,
but it is unclear at this point in time when that work will be ready
for inclusion in the mainline kernel.  In the interest of not keeping
objectionable code in the kernel for multiple weeks, and potentially
a kernel release, we are reverting the two problematic patches.

TCP Receive zerocopy iterates through the SKB queue via
tcp_recv_skb(), acquiring a pointer to an SKB and an offset within
that SKB to read from. From there, it iterates the SKB frags array to
determine which offset to start remapping pages from.

However, this is built on the assumption that the offset read so far
within the SKB is smaller than the SKB length. If this assumption is
violated, we can attempt to read an invalid frags array element, which
would cause a fault.

tcp_recv_skb() can cause such an SKB to be returned when the TCP FIN
flag is set. Therefore, we must guard against this occurrence inside
skb_advance_frag().

One way that we can reproduce this error follows:
1) In a receiver program, call getsockopt(TCP_ZEROCOPY_RECEIVE) with:
char some_array[32 * 1024];
struct tcp_zerocopy_receive zc = {
  .copybuf_address  = (__u64) &some_array[0],
  .copybuf_len = 32 * 1024,
};

2) In a sender program, after a TCP handshake, send the following
sequence of packets:
  i) Seq = [X, X+4000]
  ii) Seq = [X+4000, X+5000]
  iii) Seq = [X+4000, X+5000], Flags = FIN | URG, urgptr=1000

(This can happen without URG, if we have a signal pending, but URG is
a convenient way to reproduce the behaviour).

In this case, the following event sequence will occur on the receiver:

tcp_zerocopy_receive():
-> receive_fallback_to_copy() // copybuf_len >= inq
-> tcp_recvmsg_locked() // reads 5000 bytes, then breaks due to URG
-> tcp_recv_skb() // yields skb with skb->len == offset
-> tcp_zerocopy_set_hint_for_skb()
-> skb_advance_to_frag() // will returns a frags ptr. >= nr_frags
-> find_next_mappable_frag() // will dereference this bad frags ptr.

With this patch, skb_advance_to_frag() will no longer return an
invalid frags pointer, and will return NULL instead, fixing the issue.

The former patch "defer 6pack kfree after unregister_netdev" reorders
the kfree of two buffer after the unregister_netdev to prevent the race
condition. It also adds free_netdev() function in sixpack_close(), which
is a direct copy from the similar code in mkiss_close().

However, in sixpack driver, the flag needs_free_netdev is set to true in
sp_setup(), hence the unregister_netdev() will free the netdev
automatically. Therefore, as the sp is netdev_priv, use-after-free
occurs.

This patch removes the needs_free_netdev = true and just let the
free_netdev to finish this deallocation task.

Pull RTC updates from Alexandre Belloni:

  Summary:

  Subsystem:
   - Add new ioctl to get and set extra RTC parameters, this includes
     backup switch mode
   - Expose available features to userspace, in particular, when alarmas
     have a resolution of one minute instead of a second.
   - Let the core handle those alarms with a minute resolution

TL;DR: While a tool like liblockdep is useful, it probably doesn't
belong within the kernel tree.

liblockdep attempts to reuse kernel code both directly (by directly
building the kernel's lockdep code) as well as indirectly (by using
sanitized headers). This makes liblockdep an integral part of the
kernel.

It also makes liblockdep quite unique: while other userspace code might
use sanitized headers, it generally doesn't attempt to use kernel code
directly which means that changes on the kernel side of things don't
affect (and break) it directly.

All our workflows and tooling around liblockdep don't support this
uniqueness. Changes that go into the kernel code aren't validated to not
break in-tree userspace code.

liblockdep ended up being very fragile, breaking over and over, to the
point that living in the same tree as the lockdep code lost most of it's
value.

liblockdep should continue living in an external tree, syncing with
the kernel often, in a controllable way.

Commit aeb58c86 ("thermal/drivers/int340x: processor_thermal: Suppot
64 bit RFIM responses") started using 'readq()' to read 64-bit status
responses from the int340x hardware.

That's all fine and good, but on 32-bit targets a 64-bit 'readq()' is
ambiguous, since it's no longer an atomic access.  Some hardware might
require 64-bit accesses, and other hardware might want low word first or
high word first.

It's quite likely that the driver isn't relevant in a 32-bit environment
any more, and there's a patch floating around to just make it depend on
X86_64, but let's make it buildable on x86-32 anyway.

The driver previously just read the low 32 bits, so the hardware
certainly is ok with 32-bit reads, and in a little-endian environment
the low word first model is the natural one.

So just add the include for the 'io-64-nonatomic-lo-hi.h' version.

Pull PCI fixes from Bjorn Helgaas:
 "Revert conversion to struct device.driver instead of struct
  pci_dev.driver.

  The device.driver is set earlier, and using it caused the PCI core to
  call driver PM entry points before .probe() and after .remove(), when
  the driver isn't prepared.

  This caused NULL pointer dereferences in i2c_designware_pci and
  probably other driver issues"

ACS-3 introduced the ATA Identify Device Data log as mandatory. A
warning message currently signals to the user if a device does not
report supporting this log page in the log directory page, regardless
of the ATA version of the device. Furthermore, this warning will appear
for all attempts at accessing this missing log page during device
revalidation.

Since it is useless to constantly access the log directory and warn
about this lack of support once we have discovered that the device
does not support this log page, introduce the horkage flag
ATA_HORKAGE_NO_ID_DEV_LOG to mark a device as lacking support for
the Identify Device Data log page. Set this flag when
ata_log_supported() returns false in ata_identify_page_supported().
The warning is printed only if the device ATA level is 10 or above
(ACS-3 or above), and only once on device scan. With this flag set, the
log directory page is not accessed again to test for Identify Device
Data log page support.
