beac83e8bd selftests/gpio: Use TEST_GEN_PROGS_EXTENDED
[ Upstream commit ff2c395b9257f0e617f9cd212893f3c72c80ee6c ]

Use TEST_GEN_PROGS_EXTENDED rather than TEST_PROGS_EXTENDED.

That tells the lib.mk logic that the files it references are to be
generated by the Makefile.

Having done that we don't need to override the all rule.

1a8ecc3cd1 dm snapshot: properly fix a crash when an origin has no snapshots
commit 7e768532b2396bcb7fbf6f82384b85c0f1d2f197 upstream.

If an origin target has no snapshots, o->split_boundary is set to 0.
This causes BUG_ON(sectors <= 0) in block/bio.c:bio_split().

Fix this by initializing chunk_size, and in turn split_boundary, to
rounddown_pow_of_two(UINT_MAX) -- the largest power of two that fits
into "unsigned" type.

cc5d84b1b0 ath11k: Clear the fragment cache during key install
commit c3944a5621026c176001493d48ee66ff94e1a39a upstream.

Currently the fragment cache setup during peer assoc is
cleared only during peer delete. In case a key reinstallation
happens with the same peer, the same fragment cache with old
fragments added before key installation could be clubbed
with fragments received after. This might be exploited
to mix fragments of different data resulting in a proper
unintended reassembled packet to be passed up the stack.

Hence flush the fragment cache on every key installation to prevent
potential attacks (CVE-2020-24587).

8135f46f5a ath10k: Validate first subframe of A-MSDU before processing the list
commit 62a8ff67eba52dae9b107e1fb8827054ed00a265 upstream.

In certain scenarios a normal MSDU can be received as an A-MSDU when
the A-MSDU present bit of a QoS header gets flipped during reception.
Since this bit is unauthenticated, the hardware crypto engine can pass
the frame to the driver without any error indication.

This could result in processing unintended subframes collected in the
A-MSDU list. Hence, validate A-MSDU list by checking if the first frame
has a valid subframe header.

Comparing the non-aggregated MSDU and an A-MSDU, the fields of the first
subframe DA matches the LLC/SNAP header fields of a normal MSDU.
In order to avoid processing such frames, add a validation to
filter such A-MSDU frames where the first subframe header DA matches
with the LLC/SNAP header pattern.

6643b21aee ath10k: Fix TKIP Michael MIC verification for PCIe
commit 0dc267b13f3a7e8424a898815dd357211b737330 upstream.

TKIP Michael MIC was not verified properly for PCIe cases since the
validation steps in ieee80211_rx_h_michael_mic_verify() in mac80211 did
not get fully executed due to unexpected flag values in
ieee80211_rx_status.

Fix this by setting the flags property to meet mac80211 expectations for
performing Michael MIC validation there. This fixes CVE-2020-26141. It
does the same as ath10k_htt_rx_proc_rx_ind_hl() for SDIO which passed
MIC verification case. This applies only to QCA6174/QCA9377 PCIe.

c17b3e1ffc ath10k: add CCMP PN replay protection for fragmented frames for PCIe
commit a1166b2653db2f3de7338b9fb8a0f6e924b904ee upstream.

PN replay check for not fragmented frames is finished in the firmware,
but this was not done for fragmented frames when ath10k is used with
QCA6174/QCA6377 PCIe. mac80211 has the function
ieee80211_rx_h_defragment() for PN replay check for fragmented frames,
but this does not get checked with QCA6174 due to the
ieee80211_has_protected() condition not matching the cleared Protected
bit case.

Validate the PN of received fragmented frames within ath10k when CCMP is
used and drop the fragment if the PN is not correct (incremented by
exactly one from the previous fragment). This applies only for
QCA6174/QCA6377 PCIe.

6abcc01e8b mac80211: extend protection against mixed key and fragment cache attacks
commit 3edc6b0d6c061a70d8ca3c3c72eb1f58ce29bfb1 upstream.

For some chips/drivers, e.g., QCA6174 with ath10k, the decryption is
done by the hardware, and the Protected bit in the Frame Control field
is cleared in the lower level driver before the frame is passed to
mac80211. In such cases, the condition for ieee80211_has_protected() is
not met in ieee80211_rx_h_defragment() of mac80211 and the new security
validation steps are not executed.

Extend mac80211 to cover the case where the Protected bit has been
cleared, but the frame is indicated as having been decrypted by the
hardware. This extends protection against mixed key and fragment cache
attack for additional drivers/chips. This fixes CVE-2020-24586 and
CVE-2020-24587 for such cases.

2b9b07b9a0 mac80211: do not accept/forward invalid EAPOL frames
commit a8c4d76a8dd4fb9666fc8919a703d85fb8f44ed8 upstream.

EAPOL frames are used for authentication and key management between the
AP and each individual STA associated in the BSS. Those frames are not
supposed to be sent by one associated STA to another associated STA
(either unicast for broadcast/multicast).

Similarly, in 802.11 they're supposed to be sent to the authenticator
(AP) address.

Since it is possible for unexpected EAPOL frames to result in misbehavior
in supplicant implementations, it is better for the AP to not allow such
cases to be forwarded to other clients either directly, or indirectly if
the AP interface is part of a bridge.

Accept EAPOL (control port) frames only if they're transmitted to the
own address, or, due to interoperability concerns, to the PAE group
address.

Disable forwarding of EAPOL (or well, the configured control port
protocol) frames back to wireless medium in all cases. Previously, these
frames were accepted from fully authenticated and authorized stations
and also from unauthenticated stations for one of the cases.

Additionally, to avoid forwarding by the bridge, rewrite the PAE group
address case to the local MAC address.

However, this also somewhat protects potential other algorithms

e64ea05970 mac80211: check defrag PN against current frame
commit bf30ca922a0c0176007e074b0acc77ed345e9990 upstream.

As pointed out by Mathy Vanhoef, we implement the RX PN check
on fragmented frames incorrectly - we check against the last
received PN prior to the new frame, rather than to the one in
this frame itself.

Prior patches addressed the security issue here, but in order
to be able to reason better about the code, fix it to really
compare against the current frame's PN, not the last stored
one.

f51fe83ead mac80211: add fragment cache to sta_info
commit 3a11ce08c45b50d69c891d71760b7c5b92074709 upstream.

Prior patches protected against fragmentation cache attacks
by coloring keys, but this shows that it can lead to issues
when multiple stations use the same sequence number. Add a
fragment cache to struct sta_info (in addition to the one in
the interface) to separate fragments for different stations
properly.

This then automatically clear most of the fragment cache when a
station disconnects (or reassociates) from an AP, or when client
interfaces disconnect from the network, etc.

On the way, also fix the comment there since this brings us in line
with the recommendation in 802.11-2016 ("An AP should support ...").
Additionally, remove a useless condition (since there's no problem
purging an already empty list).

9b21fcae6f mac80211: drop A-MSDUs on old ciphers
commit 270032a2a9c4535799736142e1e7c413ca7b836e upstream.

With old ciphers (WEP and TKIP) we shouldn't be using A-MSDUs
since A-MSDUs are only supported if we know that they are, and
the only practical way for that is HT support which doesn't
support old ciphers.

However, we would normally accept them anyway. Since we check
the MMIC before deaggregating A-MSDUs, and the A-MSDU bit in
the QoS header is not protected in TKIP (or WEP), this enables
attacks similar to CVE-2020-24588. To prevent that, drop A-MSDUs
completely with old ciphers.

c730d72aa6 cfg80211: mitigate A-MSDU aggregation attacks
commit 2b8a1fee3488c602aca8bea004a087e60806a5cf upstream.

Mitigate A-MSDU injection attacks (CVE-2020-24588) by detecting if the
destination address of a subframe equals an RFC1042 (i.e., LLC/SNAP)
header, and if so dropping the complete A-MSDU frame. This mitigates
known attacks, although new (unknown) aggregation-based attacks may
remain possible.

This defense works because in A-MSDU aggregation injection attacks, a
normal encrypted Wi-Fi frame is turned into an A-MSDU frame. This means
the first 6 bytes of the first A-MSDU subframe correspond to an RFC1042
header. In other words, the destination MAC address of the first A-MSDU
subframe contains the start of an RFC1042 header during an aggregation
attack. We can detect this and thereby prevent this specific attack.
For details, see Section 7.2 of "Fragment and Forge: Breaking Wi-Fi
Through Frame Aggregation and Fragmentation".

Note that for kernel 4.9 and above this patch depends on "mac80211:
properly handle A-MSDUs that start with a rfc1042 header". Otherwise
this patch has no impact and attacks will remain possible.

commit a1d5ff5651ea592c67054233b14b30bf4452999c upstream.

Properly parse A-MSDUs whose first 6 bytes happen to equal a rfc1042
header. This can occur in practice when the destination MAC address
equals AA:AA:03:00:00:00. More importantly, this simplifies the next
patch to mitigate A-MSDU injection attacks.

42d98e0219 mac80211: prevent mixed key and fragment cache attacks
commit 94034c40ab4a3fcf581fbc7f8fdf4e29943c4a24 upstream.

Simultaneously prevent mixed key attacks (CVE-2020-24587) and fragment
cache attacks (CVE-2020-24586). This is accomplished by assigning a
unique color to every key (per interface) and using this to track which
key was used to decrypt a fragment. When reassembling frames, it is
now checked whether all fragments were decrypted using the same key.

To assure that fragment cache attacks are also prevented, the ID that is
assigned to keys is unique even over (re)associations and (re)connects.
This means fragments separated by a (re)association or (re)connect will
not be reassembled. Because mac80211 now also prevents the reassembly of
mixed encrypted and plaintext fragments, all cache attacks are prevented.

f7829b014b mac80211: assure all fragments are encrypted
commit 965a7d72e798eb7af0aa67210e37cf7ecd1c9cad upstream.

Do not mix plaintext and encrypted fragments in protected Wi-Fi
networks. This fixes CVE-2020-26147.

Previously, an attacker was able to first forward a legitimate encrypted
fragment towards a victim, followed by a plaintext fragment. The
encrypted and plaintext fragment would then be reassembled. For further
details see Section 6.3 and Appendix D in the paper "Fragment and Forge:
Breaking Wi-Fi Through Frame Aggregation and Fragmentation".

Because of this change there are now two equivalent conditions in the
code to determine if a received fragment requires sequential PNs, so we
also move this test to a separate function to make the code easier to
maintain.

that is, nft_pipapo_avx2_lookup() uses the FPU running from a softirq
that interrupted a kthread, also using the FPU.

That's exactly the reason why irq_fpu_usable() is there: use it, and
if we can't use the FPU, fall back to the non-AVX2 version of the
lookup operation, i.e. nft_pipapo_lookup().

e583eb5e72 net/sched: fq_pie: re-factor fix for fq_pie endless loop
commit 3a62fed2fd7b6fea96d720e779cafc30dfb3a22e upstream.

the patch that fixed an endless loop in_fq_pie_init() was not considering
that 65535 is a valid class id. The correct bugfix for this infinite loop
is to change 'idx' to become an u32, like Colin proposed in the past [1].

Fix this as follows:
 - restore 65536 as maximum possible values of 'flows_cnt'
 - use u32 'idx' when iterating on 'q->flows'
 - fix the TDC selftest

This reverts commit bb2f930d6d.

commit 1a6e9a9c68c1f183872e4bcc947382111c2e04eb upstream.

The direction of the pipe argument must match the request-type direction
bit or control requests may fail depending on the host-controller-driver
implementation.

Fix the tiocmset and rfkill requests which erroneously used
usb_rcvctrlpipe().

fb003a1bd6 proc: Check /proc/$pid/attr/ writes against file opener
commit bfb819ea20ce8bbeeba17e1a6418bf8bda91fc28 upstream.

Fix another "confused deputy" weakness[1]. Writes to /proc/$pid/attr/
files need to check the opener credentials, since these fds do not
transition state across execve(). Without this, it is possible to
trick another process (which may have different credentials) to write
to its own /proc/$pid/attr/ files, leading to unexpected and possibly
exploitable behaviors.

03b777ce8d perf scripts python: exported-sql-viewer.py: Fix warning display
commit f56299a9c998e0bfbd4ab07cafe9eb8444512448 upstream.

Deprecation warnings are useful only for the developer, not an end user.
Display warnings only when requested using the python -W option. This
stops the display of warnings like:

 tools/perf/scripts/python/exported-sql-viewer.py:5102: DeprecationWarning:
         an integer is required (got type PySide2.QtCore.Qt.AlignmentFlag).
         Implicit conversion to integers using __int__ is deprecated, and
         may be removed in a future version of Python.
    err = app.exec_()

Since the warning can be fixed only in PySide2, we must wait for it to
be finally fixed there.

commit fd931b2e234a7cc451a7bbb1965d6ce623189158 upstream.

The 'Array' class is present in more than one python standard library.
In some versions of Python 3, the following error occurs:

Traceback (most recent call last):

TypeError: abstract class

This apparently happens because Python can be inconsistent about which
class of the name 'Array' gets imported. Fix by importing explicitly by
name so that only the desired 'Array' gets imported.

7285b92dc5 perf intel-pt: Fix transaction abort handling
commit cb7987837c31b217b28089bbc78922d5c9187869 upstream.

When adding support for power events, some handling of FUP packets was
unified. That resulted in breaking reporting of TSX aborts, by not
considering the associated TIP packet. Fix that.

Example:

A machine that supports TSX is required. It will have flag "rtm". Kernel
parameter tsx=on may be required.

 # for w in `cat /proc/cpuinfo | grep -m1 flags `;do echo $w | grep rtm ; done
 rtm

Test program:

 #include <stdio.h>
 #include <immintrin.h>

 int main()
 {
        int x = 0;

        if (_xbegin() == _XBEGIN_STARTED) {
                x = 1;
                _xabort(1);
        } else {
                printf("x = %d\n", x);
        }
        return 0;
 }

Compile with -mrtm i.e.

 gcc -Wall -Wextra -mrtm xabort.c -o xabort

ce3ea6b66d perf intel-pt: Fix sample instruction bytes
commit c954eb72b31a9dc56c99b450253ec5b121add320 upstream.

The decoder reports the current instruction if it was decoded. In some
cases the current instruction is not decoded, in which case the instruction
bytes length must be set to zero. Ensure that is always done.

Note perf script can anyway get the instruction bytes for any samples where
they are not present.

Also note, that there is a redundant "ptq->insn_len = 0" statement which is
not removed until a subsequent patch in order to make this patch apply
cleanly to stable branches.

Example:

A machne that supports TSX is required. It will have flag "rtm". Kernel
parameter tsx=on may be required.

 # for w in `cat /proc/cpuinfo | grep -m1 flags `;do echo $w | grep rtm ; done
 rtm

Test program:

 #include <stdio.h>
 #include <immintrin.h>

 int main()
 {
        int x = 0;

        if (_xbegin() == _XBEGIN_STARTED) {
                x = 1;
                _xabort(1);
        } else {
                printf("x = %d\n", x);
        }
        return 0;
 }

Compile with -mrtm i.e.

 gcc -Wall -Wextra -mrtm xabort.c -o xabort

Record:

pnfs_mark_matching_lsegs_return() doesn't check if we have a value here
before dereferencing it, causing an oops.

3e5b48d9e7 cifs: set server->cipher_type to AES-128-CCM for SMB3.0
commit 6d2fcfe6b517fe7cbf2687adfb0a16cdcd5d9243 upstream.

SMB3.0 doesn't have encryption negotiate context but simply uses
the SMB2_GLOBAL_CAP_ENCRYPTION flag.

When that flag is present in the neg response cifs.ko uses AES-128-CCM
which is the only cipher available in this context.

cipher_type was set to the server cipher only when parsing encryption
negotiate context (SMB3.1.1).

For SMB3.0 it was set to 0. This means cipher_type value can be 0 or 1
for AES-128-CCM.

Fix this by checking for SMB3.0 and encryption capability and setting
cipher_type appropriately.

7573b58a2d ALSA: hda/realtek: fix mute/micmute LEDs and speaker for HP Zbook Fury 15 G8
commit e650c1a959da49f2b873cb56564b825882c22e7a upstream.

The HP ZBook Fury 15.6 Inch G8 is using ALC285 codec which is
using 0x04 to control mute LED and 0x01 to control micmute LED.
In the other hand, there is no output from right channel of speaker.
Therefore, add a quirk to make it works.

commit 0e68c4b11f1e66d211ad242007e9f1076a6b7709 upstream.

The HP EliteBook 855 G8 Notebook PC is using ALC285 codec which needs
ALC285_FIXUP_HP_MUTE_LED fixup to make it works. After applying the
fixup, the mute/micmute LEDs work good.

7906018de7 ALSA: hda/realtek: Chain in pop reduction fixup for ThinkStation P340
commit 29c8f40b54a45dd23971e2bc395697731bcffbe1 upstream.

Lenovo ThinkStation P340 uses ALC623 codec (SSID 17aa:1048) and it produces
bug plock/pop noise over line out (green jack on the back) which can be
fixed by applying ALC269_FIXUP_NO_SHUTUP tot he machine.

Convert the existing entry for the same SSID to chain to apply this fixup
as well.

2f0f8e06e7 ALSA: hda/realtek: Headphone volume is controlled by Front mixer
commit 119b75c150773425a89033215eab4d15d4198f8b upstream.

On some ASUS and MSI machines, the audio codec is alc1220 and the
Headphone is connected to audio mixer 0xf and DAC 0x5, in theory
the Headphone volume is controlled by DAC 0x5 (Heapdhone Playback
Volume), but somehow it is controlled by DAC 0x2 (Front Playback
Volume), maybe this is a defect on the codec alc1220.

Because of this issue, the PA couldn't switch the headphone and
Lineout correctly, If we apply the quirk CLEVO_P950 to those machines,
the Lineout and Headphone will share the audio mixer 0xc and DAC 0x2,
and generate Headphone+LO mixer, then PA could handle them when
switching between them.

8ca63ce027 ALSA: hda/realtek: the bass speaker can't output sound on Yoga 9i
commit 9ebaef0540a981093bce5df15af32354d32391d9 upstream.

The Lenovo Yoga 9i has bass speaker, but the bass speaker can't work,
that is because there is an i2s amplifier on that speaker, need to
run ideapad_s740_coef() to initialize the amplifier.

And also needs to apply ALC285_FIXUP_THINKPAD_HEADSET_JACK to rename
the speaker's mixer control name, otherwise the PA can't handle them.

8d11e6ae43 perf unwind: Set userdata for all __report_module() paths
commit 4e1481445407b86a483616c4542ffdc810efb680 upstream.

When locating the DWARF module for a given address, __find_debuginfo()
requires a 'struct dso' passed via the userdata argument.

However, this field is only set in __report_module() if the module is
found in via dwfl_addrmodule(), not if it is found later via
dwfl_report_elf().

Set userdata irrespective of how the DWARF module was found, as long as
we found a module.
