<title>Revert "ata: libata-scsi: Honor the D_SENSE bit for CK_COND=1 and no error"</title>

<id>urn:sha1:b2c5a0f32c6cc517635de288594443c2dba4c5ac</id>
<content type='text'>
commit fa0db8e568787c665384430eaf2221b299b85367 upstream.

This reverts commit 28ab9769117ca944cb6eb537af5599aa436287a4.

Sense data can be in either fixed format or descriptor format.

SAT-6 revision 1, "10.4.6 Control mode page", defines the D_SENSE bit:
"The SATL shall support this bit as defined in SPC-5 with the following
exception: if the D_ SENSE bit is set to zero (i.e., fixed format sense
data), then the SATL should return fixed format sense data for ATA
PASS-THROUGH commands."

The libata SATL has always kept D_SENSE set to zero by default. (It is
however possible to change the value using a MODE SELECT SG_IO command.)

Failed ATA PASS-THROUGH commands correctly respected the D_SENSE bit,
however, successful ATA PASS-THROUGH commands incorrectly returned the
sense data in descriptor format (regardless of the D_SENSE bit).

Commit 28ab9769117c ("ata: libata-scsi: Honor the D_SENSE bit for
CK_COND=1 and no error") fixed this bug for successful ATA PASS-THROUGH
commands.

However, after commit 28ab9769117c ("ata: libata-scsi: Honor the D_SENSE
bit for CK_COND=1 and no error"), there were bug reports that hdparm,
hddtemp, and udisks were no longer working as expected.

These applications incorrectly assume the returned sense data is in
descriptor format, without even looking at the RESPONSE CODE field in the
returned sense data (to see which format the returned sense data is in).

Considering that there will be broken versions of these applications around
roughly forever, we are stuck with being bug compatible with older kernels.

commit 0c84bde4f37ba27d50e4c70ecacd33fe4a57030d upstream.

This reverts commit 2052138b7da52ad5ccaf74f736d00f39a1c9198c.

This breaks the TeVii s480 dual DVB-S2 S660. The device has a bulk in
endpoint but no corresponding out endpoint, so the device does not pass
the "has both receive and send bulk endpoint" test.

Seemingly this device does not use dvb_usb_generic_rw() so I have tried
removing the generic_bulk_ctrl_endpoint entry, but this resulted in
different problems.

As we have no explanation yet, revert.

commit 0df3c7d7a73d75153090637392c0b73a63cdc24a upstream.

The i.MX6 cannot add any RGMII delays. The PHY has to add both the RX
and TX delays on the RGMII interface. Fix the interface mode. While at
it, use the new phy-connection-type property name.

[ Upstream commit d1cba2ea8121e7fdbe1328cea782876b1dd80993 ]

syzbot is able to trigger softlockups, setting NL80211_ATTR_TXQ_QUANTUM
to 2^31.

We had a similar issue in sch_fq, fixed with commit
d9e15a273306 ("pkt_sched: fq: do not accept silly TCA_FQ_QUANTUM")

[ Upstream commit 3eb3cd5992f7a0c37edc8d05b4c38c98758d8671 ]

Commit 04d82a6d0881 ("binfmt_flat: allow not offsetting data start")
introduced a RISC-V specific variant of the FLAT format which does
not allocate any space for the (obsolete) array of shared library
pointers. However, it did not disable the code which initializes the
array, resulting in the corruption of sizeof(long) bytes before the DATA
segment, generally the end of the TEXT segment.

Introduce MAX_SHARED_LIBS_UPDATE which depends on the state of
CONFIG_BINFMT_FLAT_NO_DATA_START_OFFSET to guard the initialization of
the shared library pointer region so that it will only be initialized
if space is reserved for it.

commit ab091ec536cb7b271983c0c063b17f62f3591583 upstream.

There is a hardware power-saving problem with the Lenovo N60z
board. When turn it on and leave it for 10 hours, there is a
20% chance that a nvme disk will not wake up until reboot.

<title>exec: Fix ToCToU between perm check and set-uid/gid usage</title>

commit f50733b45d865f91db90919f8311e2127ce5a0cb upstream.

When opening a file for exec via do_filp_open(), permission checking is
done against the file's metadata at that moment, and on success, a file
pointer is passed back. Much later in the execve() code path, the file
metadata (specifically mode, uid, and gid) is used to determine if/how
to set the uid and gid. However, those values may have changed since the
permissions check, meaning the execution may gain unintended privileges.

For example, if a file could change permissions from executable and not
set-id:

---------x 1 root root 16048 Aug  7 13:16 target

to set-id and non-executable:

---S------ 1 root root 16048 Aug  7 13:16 target

it is possible to gain root privileges when execution should have been
disallowed.

While this race condition is rare in real-world scenarios, it has been
observed (and proven exploitable) when package managers are updating
the setuid bits of installed programs. Such files start with being
world-executable but then are adjusted to be group-exec with a set-uid
bit. For example, "chmod o-x,u+s target" makes "target" executable only
by uid "root" and gid "cdrom", while also becoming setuid-root:

-rwxr-xr-x 1 root cdrom 16048 Aug  7 13:16 target

becomes:

-rwsr-xr-- 1 root cdrom 16048 Aug  7 13:16 target

But racing the chmod means users without group "cdrom" membership can
get the permission to execute "target" just before the chmod, and when
the chmod finishes, the exec reaches brpm_fill_uid(), and performs the
setuid to root, violating the expressed authorization of "only cdrom
group members can setuid to root".

Re-check that we still have execute permissions in case the metadata
has changed. It would be better to keep a copy from the perm-check time,
but until we can do that refactoring, the least-bad option is to do a
full inode_permission() call (under inode lock). It is understood that
this is safe against dead-locks, but hardly optimal.

<title>arm64: cpufeature: Fix the visibility of compat hwcaps</title>

commit 85f1506337f0c79a4955edfeee86a18628e3735f upstream.

Commit 237405ebef58 ("arm64: cpufeature: Force HWCAP to be based on the
sysreg visible to user-space") forced the hwcaps to use sanitised
user-space view of the id registers. However, the ID register structures
used to select few compat cpufeatures (vfp, crc32, ...) are masked and
hence such hwcaps do not appear in /proc/cpuinfo anymore for PER_LINUX32
personality.

Add the ID register structures explicitly and set the relevant entry as
visible. As these ID registers are now of type visible so make them
available in 64-bit userspace by making necessary changes in register
emulation logic and documentation.

While at it, update the comment for structure ftr_generic_32bits[] which
lists the ID register that use it.
