[ Upstream commit 18e4960c18 ]
The driver currently only calls netdev_set_tc_queue when the number of
TCs is greater than 1. Instead, the comparison should be greater than
or equal to 1. Even with 1 TC, we need to set the queue mapping.
This bug can cause warnings when the number of TCs is changed back to 1.

It's found that stmmac_xmit() and stmmac_resume() sometimes might
run concurrently, possibly resulting in a race condition between
mod_timer() and setup_timer(), being called by stmmac_xmit() and
stmmac_resume() respectively.
Since the resume() runs setup_timer() every time, it'd be safer to
have del_timer_sync() in the suspend() as the counterpart.

[ Upstream commit 0d0d9a388a ]
In the past it was possible to create multiple L2TPv3 sessions with the
same session id as long as the sessions belonged to different tunnels.
The resulting sessions had issues when used with IP encapsulated tunnels,
but worked fine with UDP encapsulated ones. Some applications began to
rely on this behaviour to avoid having to negotiate unique session ids.
Some time ago a change was made to require session ids to be unique across
all tunnels, breaking the applications making use of this "feature".
This change relaxes the duplicate session id check to allow duplicates
if both of the colliding sessions belong to UDP encapsulated tunnels.

As discussed in the strace issue tracker, it appears that the sparc32
sysvipc support has been broken for the past 11 years. It was however
working in compat mode, which is how it must have escaped most of the
regular testing.
The problem is that a cleanup patch inadvertently changed the uid/gid
fields in struct ipc64_perm from 32-bit types to 16-bit types in uapi
headers.
Both glibc and uclibc-ng still use the original types, so they should
work fine with compat mode, but not natively. Change the definitions
to use __kernel_uid32_t and __kernel_gid32_t again.

Commit f92b070f2d ("printk: Do not miss new messages when replaying

store when an exclusive console should stop printing. It should be
set to the @console_seq value at registration. However, @console_seq
is previously set to @syslog_seq so that the exclusive console knows
where to begin. This results in the exclusive console immediately
reactivating all the other consoles and thus repeating the messages
for those consoles.
Set @console_seq after @exclusive_console_stop_seq has stored the
current @console_seq value.

UDF 2.60 standard states in section 2.2.14.2:
A partition with Access Type 3 (rewritable) shall define a Freed
Space Bitmap or a Freed Space Table, see 2.3.3. All other partitions
shall not define a Freed Space Bitmap or a Freed Space Table.
Rewritable partitions are used on media that require some form of
preprocessing before re-writing data (for example legacy MO). Such
partitions shall use Access Type 3.
Overwritable partitions are used on media that do not require
preprocessing before overwriting data (for example: CD-RW, DVD-RW,
DVD+RW, DVD-RAM, BD-RE, HD DVD-Rewritable). Such partitions shall
use Access Type 4.
however older versions of the standard didn't have this wording and
there are tools out there that create UDF filesystems with rewritable
partitions but that don't contain a Freed Space Bitmap or a Freed Space
Table on media that does not require pre-processing before overwriting a
block. So instead of forcing media with rewritable partition read-only,
base this decision on presence of a Freed Space Bitmap or a Freed Space
Table.

there're two ways to add this delay -- add it in DSI controller or add
it in the TCON. Add it in both controllers won't work.
The code before this commit is picked from new versions of BSP kernel,
which has a comment for the 1 that says "put start_delay to tcon". By
checking the sun4i_tcon0_mode_set_cpu() in sun4i_tcon driver, it has
already added this delay, so we shouldn't repeat to add the delay in DSI
controller, otherwise the timing won't match.

commit d55966c427 upstream.
There was some logic added a while ago to clear out f_bavail in statfs()
if we did not have enough free metadata space to satisfy our global
reserve. This was incorrect at the time, however didn't really pose a
problem for normal file systems because we would often allocate chunks
if we got this low on free metadata space, and thus wouldn't really hit
this case unless we were actually full.
Fast forward to today and now we are much better about not allocating
metadata chunks all of the time. Couple this with d792b0f197 ("btrfs:
always reserve our entire size for the global reserve") which now means
we'll easily have a larger global reserve than our free space, we are
now more likely to trip over this while still having plenty of space.
Fix this by skipping this logic if the global rsv's space_info is not
full. space_info->full is 0 unless we've attempted to allocate a chunk
for that space_info and that has failed. If this happens then the space
for the global reserve is definitely sacred and we need to report
b_avail == 0, but before then we can just use our calculated b_avail.

The driver for Cisco Aironet 4500 and 4800 series cards (airo.c),
implements AIROOLDIOCTL/SIOCDEVPRIVATE in airo_ioctl().
The ioctl handler copies an aironet_ioctl struct from userspace, which
includes a command. Some of the commands are handled in readrids(),
where the user controlled command is converted into a driver-internal
value called "ridcode".
There are two command values, AIROGWEPKTMP and AIROGWEPKNV, which
correspond to ridcode values of RID_WEP_TEMP and RID_WEP_PERM
respectively. These commands both have checks that the user has
CAP_NET_ADMIN, with the comment that "Only super-user can read WEP
keys", otherwise they return -EPERM.
However there is another command value, AIRORRID, that lets the user
specify the ridcode value directly, with no other checks. This means
the user can bypass the CAP_NET_ADMIN check on AIROGWEPKTMP and
AIROGWEPKNV.
Fix it by moving the CAP_NET_ADMIN check out of the command handling
and instead do it later based on the ridcode. That way regardless of
whether the ridcode is set via AIROGWEPKTMP or AIROGWEPKNV, or passed
in using AIRORID, we always do the CAP_NET_ADMIN check.

The driver for Cisco Aironet 4500 and 4800 series cards (airo.c),
implements AIROOLDIOCTL/SIOCDEVPRIVATE in airo_ioctl().
The ioctl handler copies an aironet_ioctl struct from userspace, which
includes a command and a length. Some of the commands are handled in
readrids(), which kmalloc()'s a buffer of RIDSIZE (2048) bytes.
That buffer is then passed to PC4500_readrid(), which has two cases.
The else case does some setup and then reads up to RIDSIZE bytes from
the hardware into the kmalloc()'ed buffer.
Here len == RIDSIZE, pBuf is the kmalloc()'ed buffer:
// read the rid length field
bap_read(ai, pBuf, 2, BAP1);
// length for remaining part of rid
len = min(len, (int)le16_to_cpu(*(__le16*)pBuf)) - 2;
...
// read remainder of the rid
rc = bap_read(ai, ((__le16*)pBuf)+1, len, BAP1);
PC4500_readrid() then returns to readrids() which does:
len = comp->len;
if (copy_to_user(comp->data, iobuf, min(len, (int)RIDSIZE))) {
Where comp->len is the user controlled length field.
So if the "rid length field" returned by the hardware is < 2048, and
the user requests 2048 bytes in comp->len, we will leak the previous
contents of the kmalloc()'ed buffer to userspace.
Fix it by kzalloc()'ing the buffer.

When a link is going down the driver will be calling fnic_cleanup_io(),
which will traverse all commands and calling 'done' for each found command.
While the traversal is handled under the host_lock, calling 'done' happens
after the host_lock is being dropped.
As fnic_queuecommand_lck() is being called with the host_lock held, it
might well be that it will pick the command being selected for abortion
from the above routine and enqueue it for sending, but then 'done' is being
called on that very command from the above routine.
Which of course confuses the hell out of the scsi midlayer.
So fix this by not queueing commands when fnic_cleanup_io is active.

mrproper: vdso-dummy.o.tmp, vdso.so.dbg.tmp.
Delete them once they're no longer needed.

Fix bnxt_fltr_match() to match ipv6 source and destination addresses.
The function currently only checks ipv4 addresses and will not work
corrently on ipv6 filters.

[ Upstream commit 8f1880cbe8 ]
With the implementation of the system reset controller we lost a setting
that is currently applied by the bootloader and which configures the IMP
port for 2Gb/sec, the default is 1Gb/sec. This is needed given the
number of ports and applications we expect to run so bring back that
setting.

[ Upstream commit e16119655c ]
After the introduction of CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE_O3,
the wext code produces a bogus warning:
In function 'iw_handler_get_iwstats',
inlined from 'ioctl_standard_call' at net/wireless/wext-core.c:1015:9,
inlined from 'wireless_process_ioctl' at net/wireless/wext-core.c:935:10,
inlined from 'wext_ioctl_dispatch.part.8' at net/wireless/wext-core.c:986:8,
inlined from 'wext_handle_ioctl':
net/wireless/wext-core.c:671:3: error: argument 1 null where non-null expected [-Werror=nonnull]
memcpy(extra, stats, sizeof(struct iw_statistics));
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In file included from arch/x86/include/asm/string.h:5,
net/wireless/wext-core.c: In function 'wext_handle_ioctl':
arch/x86/include/asm/string_64.h:14:14: note: in a call to function 'memcpy' declared here
The problem is that ioctl_standard_call() sometimes calls the handler
with a NULL argument that would cause a problem for iw_handler_get_iwstats.
However, iw_handler_get_iwstats never actually gets called that way.
Marking that function as noinline avoids the warning and leads
to slightly smaller object code as well.

[ Upstream commit 6f60126521 ]
TKIP replay protection was skipped for the very first frame received
after a new key is configured. While this is potentially needed to avoid
dropping a frame in some cases, this does leave a window for replay
attacks with group-addressed frames at the station side. Any earlier
frame sent by the AP using the same key would be accepted as a valid
frame and the internal RSC would then be updated to the TSC from that
frame. This would allow multiple previously transmitted group-addressed
frames to be replayed until the next valid new group-addressed frame
from the AP is received by the station.
Fix this by limiting the no-replay-protection exception to apply only
for the case where TSC=0, i.e., when this is for the very first frame
protected using the new key, and the local RSC had not been set to a
higher value when configuring the key (which may happen with GTK).

[ Upstream commit 26ec17a1dc ]
In case a radar event of CAC_FINISHED or RADAR_DETECTED
happens during another phy is during CAC we might need
to cancel that CAC.
If we got a radar in a channel that another phy is now
doing CAC on then the CAC should be canceled there.
If, for example, 2 phys doing CAC on the same channels,
or on comptable channels, once on of them will finish his
CAC the other might need to cancel his CAC, since it is no
longer relevant.
To fix that the commit adds an callback and implement it in
mac80211 to end CAC.
This commit also adds a call to said callback if after a radar
event we see the CAC is no longer relevant
