commit 7a8526a5cd51cf5f070310c6c37dd7293334ac49 upstream.
Many users are reporting that the Samsung 860 and 870 SSD are having
various issues when combined with AMD/ATI (vendor ID 0x1002) SATA
controllers and only completely disabling NCQ helps to avoid these
issues.
Always disabling NCQ for Samsung 860/870 SSDs regardless of the host
SATA adapter vendor will cause I/O performance degradation with well
behaved adapters. To limit the performance impact to ATI adapters,
introduce the ATA_HORKAGE_NO_NCQ_ON_ATI flag to force disable NCQ
only for these adapters.
Also, two libata.force parameters (noncqati and ncqati) are introduced
to disable and enable the NCQ for the system which equipped with ATI
SATA adapter and Samsung 860 and 870 SSDs. The user can determine NCQ
function to be enabled or disabled according to the demand.
After verifying the chipset from the user reports, the issue appears
on AMD/ATI SB7x0/SB8x0/SB9x0 SATA Controllers and does not appear on
recent AMD SATA adapters. The vendor ID of ATI should be 0x1002.
Therefore, ATA_HORKAGE_NO_NCQ_ON_AMD was modified to
ATA_HORKAGE_NO_NCQ_ON_ATI.

[ Upstream commit f81c08f897adafd2ed43f86f00207ff929f0b2eb ]
testusb' application which uses 'usbtest' driver reports 'unknown speed'
from the function 'find_testdev'. The variable 'entry->speed' was not
updated from the application. The IOCTL mentioned in the FIXME comment can
only report whether the connection is low speed or not. Speed is read using
the IOCTL USBDEVFS_GET_SPEED which reports the proper speed grade. The
call is implemented in the function 'handle_testdev' where the file
descriptor was availble locally. Sample output is given below where 'high
speed' is printed as the connected speed.

[ Upstream commit 372d1f3e1bfede719864d0d1fbf3146b1e638c88 ]
The ext2_error() function syncs the filesystem so it sleeps. The caller
is holding a spinlock so it's not allowed to sleep.
ext2_statfs() <- disables preempt
-> ext2_count_free_blocks()
-> ext2_get_group_desc()
Fix this by using WARN() to print an error message and a stack trace
instead of using ext2_error().

[ Upstream commit d8b1e10a2b8efaf71d151aa756052fbf2f3b6d57 ]
Guenter reported [1] that the pci_iounmap() changes remain problematic,
with sparc64 allnoconfig and tinyconfig still not building due to the
header file changes and confusion with the arch-specific pci_iounmap()
implementation.
I'm pretty convinced that sparc should just use GENERIC_IOMAP instead of
doing its own thing, since it turns out that the sparc64 version of
pci_iounmap() is somewhat buggy (see [2]). But in the meantime, this
just fixes the build by avoiding the trivial re-definition of the empty
case.

[ Upstream commit 3ede7f84c7c21f93c5eac611d60eba3f2c765e0f ]
When re-entering the main loop of xenvif_tx_check_gop() a 2nd time, the
special considerations for the head of the SKB no longer apply. Don't
mistakenly report ERROR to the frontend for the first entry in the list,
even if - from all I can tell - this shouldn't matter much as the overall
transmit will need to be considered failed anyway.

commit 35306eb23814444bd4021f8a1c3047d3cb0c8b2b upstream.
Jann Horn reported that SO_PEERCRED and SO_PEERGROUPS implementations
are racy, as af_unix can concurrently change sk_peer_pid and sk_peer_cred.
In order to fix this issue, this patch adds a new spinlock that needs
to be used whenever these fields are read or written.
Jann also pointed out that l2cap_sock_get_peer_pid_cb() is currently
reading sk->sk_peer_pid which makes no sense, as this field
is only possibly set by AF_UNIX sockets.
We will have to clean this in a separate patch.
This could be done by reverting b48596d1dc25 "Bluetooth: L2CAP: Add get_peer_pid callback"
or implementing what was truly expected.
Fixes: 109f6e39fa07 ("af_unix: Allow SO_PEERCRED to work across namespaces.")

commit f06bc03339ad4c1baa964a5f0606247ac1c3c50b upstream.
It is common practice for helpers like this to silently,
accept a NULL pointer.
get_rpccred() and put_rpccred() used by NFS act this way
and using the same interface will ease the conversion
for NFS, and simplify the resulting code.

commit 1e4ce418b1cb1a810256b5fb3fd33d22d1325993 upstream.
Syzbot reported slab-out-of-bounds Write bug in hid-betopff driver.
The problem is the driver assumes the device must have an input report but
some malicious devices violate this assumption.
So this patch checks hid_device's input is non empty before it's been used.

commit c0b15c25d25171db4b70cc0b7dbc1130ee94017d upstream.
The erratum 1024718 affects Cortex-A55 r0p0 to r2p0. However
we apply the work around for r0p0 - r1p0. Unfortunately this
won't be fixed for the future revisions for the CPU. Thus
extend the work around for all versions of A55, to cover
for r2p0 and any future revisions.

commit 42cb447410d024e9d54139ae9c21ea132a8c384c upstream.
When ext4_htree_fill_tree() fails, ext4_dx_readdir() can run into an
infinite loop since if info->last_pos != ctx->pos this will reset the
directory scan and reread the failing entry. For example:
1. a dx_dir which has 3 block, block 0 as dx_root block, block 1/2 as
leaf block which own the ext4_dir_entry_2
2. block 1 read ok and call_filldir which will fill the dirent and update
the ctx->pos
3. block 2 read fail, but we has already fill some dirent, so we will
return back to userspace will a positive return val(see ksys_getdents64)
4. the second ext4_dx_readdir will reset the world since info->last_pos
!= ctx->pos, and will also init the curr_hash which pos to block 1
5. So we will read block1 too, and once block2 still read fail, we can
only fill one dirent because the hash of the entry in block1(besides
the last one) won't greater than curr_hash
6. this time, we forget update last_pos too since the read for block2
will fail, and since we has got the one entry, ksys_getdents64 can
return success
7. Latter we will trapped in a loop with step 4~6

A reference to the carrier module was taken on every open but was only
released once when the final reference to the tty struct was dropped.
Fix this by taking the module reference and initialising the tty driver
data when installing the tty.

commit cd20d59291d1790dc74248476e928f57fc455189 upstream.
Registration of the ipoctal tty devices is unlikely to fail, but if it
ever does, make sure not to deregister a never registered tty device
(and dereference a NULL pointer) when the driver is later unbound.

commit a89936cce87d60766a75732a9e7e25c51164f47c upstream.
The tty driver name is used also after registering the driver and must
specifically not be allocated on the stack to avoid leaking information
to user space (or triggering an oops).
Drivers should not try to encode topology information in the tty device
name but this one snuck in through staging without anyone noticing and
another driver has since copied this malpractice.
Fixing the ABI is a separate issue, but this at least plugs the security
hole.

[ Upstream commit 51032e6f17ce990d06123ad7307f258c50d25aa7 ]
The e100_get_regs function is used to implement a simple register dump
for the e100 device. The data is broken into a couple of MAC control
registers, and then a series of PHY registers, followed by a memory dump
buffer.
The total length of the register dump is defined as (1 + E100_PHY_REGS)
* sizeof(u32) + sizeof(nic->mem->dump_buf).
The logic for filling in the PHY registers uses a convoluted inverted
count for loop which counts from E100_PHY_REGS (0x1C) down to 0, and
assigns the slots 1 + E100_PHY_REGS - i. The first loop iteration will
fill in [1] and the final loop iteration will fill in [1 + 0x1C]. This
is actually one more than the supposed number of PHY registers.
The memory dump buffer is then filled into the space at
[2 + E100_PHY_REGS] which will cause that memcpy to assign 4 bytes past
the total size.
The end result is that we overrun the total buffer size allocated by the
kernel, which could lead to a panic or other issues due to memory
corruption.
It is difficult to determine the actual total number of registers
here. The only 8255x datasheet I could find indicates there are 28 total
MDI registers. However, we're reading 29 here, and reading them in
reverse!
In addition, the ethtool e100 register dump interface appears to read
the first PHY register to determine if the device is in MDI or MDIx
mode. This doesn't appear to be documented anywhere within the 8255x
datasheet. I can only assume it must be in register 28 (the extra
register we're reading here).
Lets not change any of the intended meaning of what we copy here. Just
extend the space by 4 bytes to account for the extra register and
continue copying the data out in the same order.
Change the E100_PHY_REGS value to be the correct total (29) so that the
total register dump size is calculated properly. Fix the offset for
where we copy the dump buffer so that it doesn't overrun the total size.
Re-write the for loop to use counting up instead of the convoluted
down-counting. Correct the mdio_read offset to use the 0-based register
offsets, but maintain the bizarre reverse ordering so that we have the
ABI expected by applications like ethtool. This requires and additional
subtraction of 1. It seems a bit odd but it makes the flow of assignment
into the register buffer easier to follow.

commit abf9b902059f ("e100: cleanup unneeded math") tried to simplify
e100_get_regs_len and remove a double 'divide and then multiply'
calculation that the e100_reg_regs_len function did.
This change broke the size calculation entirely as it failed to account
for the fact that the numbered registers are actually 4 bytes wide and
not 1 byte. This resulted in a significant under allocation of the
register buffer used by e100_get_regs.
Fix this by properly multiplying the register count by u32 first before
adding the size of the dump buffer.

commit 94513069eb549737bcfc3d988d6ed4da948a2de8 upstream.
When PN checking is done in mac80211, for fragmentation we need
to copy the PN to the RX struct so we can later use it to do a
comparison, since commit bf30ca922a0c ("mac80211: check defrag
PN against current frame").
Unfortunately, in that commit I used the 'hdr' variable without
it being necessarily valid, so use-after-free could occur if it
was necessary to reallocate (parts of) the frame.
Fix this by reloading the variable after the code that results
in the reallocations, if any.
This fixes https://bugzilla.kernel.org/show_bug.cgi?id=214401.

[ Upstream commit 3b0c406124719b625b1aba431659f5cdc24a982c ]
This issue happens when a userspace program does an ioctl
FBIOPUT_VSCREENINFO passing the fb_var_screeninfo struct
containing only the fields xres, yres, and bits_per_pixel
with values.
If this struct is the same as the previous ioctl, the
vc_resize() detects it and doesn't call the resize_screen(),
leaving the fb_var_screeninfo incomplete. And this leads to
the updatescrollmode() calculates a wrong value to
fbcon_display->vrows, which makes the real_y() return a
wrong value of y, and that value, eventually, causes
the imageblit to access an out-of-bound address value.
To solve this issue I made the resize_screen() be called
even if the screen does not need any resizing, so it will
"fix and fill" the fb_var_screeninfo independently.

commit d5f6545934c47e97c0b48a645418e877b452a992 upstream.
In commit b7213ffa0e58 ("qnx4: avoid stringop-overread errors") I tried
to teach gcc about how the directory entry structure can be two
different things depending on a status flag. It made the code clearer,
and it seemed to make gcc happy.
However, Arnd points to a gcc bug, where despite using two different
members of a union, gcc then gets confused, and uses the size of one of
the members to decide if a string overrun happens. And not necessarily
the rigth one.
End result: with some configurations, gcc-11 will still complain about
the source buffer size being overread:
fs/qnx4/dir.c: In function 'qnx4_readdir':
fs/qnx4/dir.c:76:32: error: 'strnlen' specified bound [16, 48] exceeds source size 1 [-Werror=stringop-overread]
76 | size = strnlen(name, size);
| ^~~~~~~~~~~~~~~~~~~
fs/qnx4/dir.c:26:22: note: source object declared here
26 | char de_name;
| ^~~~~~~
because gcc will get confused about which union member entry is actually
getting accessed, even when the source code is very clear about it. Gcc
internally will have combined two "redundant" pointers (pointing to
different union elements that are at the same offset), and takes the
size checking from one or the other - not necessarily the right one.
This is clearly a gcc bug, but we can work around it fairly easily. The
biggest thing here is the big honking comment about why we do what we
do.

[ Upstream commit 3c0d2a46c0141913dc6fd126c57d0615677d946e ]
tx timeout and slot time are currently specified in units of HZ. On
Alpha, HZ is defined as 1024. When building alpha:allmodconfig, this
results in the following error message.
drivers/net/hamradio/6pack.c: In function 'sixpack_open':
drivers/net/hamradio/6pack.c:71:41: error:
unsigned conversion from 'int' to 'unsigned char'
changes value from '256' to '0'
In the 6PACK protocol, tx timeout is specified in units of 10 ms and
transmitted over the wire:
https://www.linux-ax25.org/wiki/6PACK
Defining a value dependent on HZ doesn't really make sense, and
presumably comes from the (very historical) situation where HZ was
originally 100.
Note that the SIXP_SLOTTIME use explicitly is about 10ms granularity:
mod_timer(&sp->tx_t, jiffies + ((when + 1) * HZ) / 100);
and the SIXP_TXDELAY walue is sent as a byte over the wire.

__stack_chk_guard is setup once while init stage and never changed
after that.
Although the modification of this variable at runtime will usually
cause the kernel to crash (so does the attacker), it should be marked
as __ro_after_init, and it should not affect performance if it is
placed in the ro_after_init section.

[ Upstream commit b7213ffa0e585feb1aee3e7173e965e66ee0abaa ]
The qnx4 directory entries are 64-byte blocks that have different
contents depending on the a status byte that is in the last byte of the
block.
In particular, a directory entry can be either a "link info" entry with
a 48-byte name and pointers to the real inode information, or an "inode
entry" with a smaller 16-byte name and the full inode information.
But the code was written to always just treat the directory name as if
it was part of that "inode entry", and just extend the name to the
longer case if the status byte said it was a link entry.
That work just fine and gives the right results, but now that gcc is
tracking data structure accesses much more, the code can trigger a
compiler error about using up to 48 bytes (the long name) in a structure
that only has that shorter name in it:
fs/qnx4/dir.c: In function ‘qnx4_readdir’:
fs/qnx4/dir.c:51:32: error: ‘strnlen’ specified bound 48 exceeds source size 16 [-Werror=stringop-overread]
51 | size = strnlen(de->di_fname, size);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~
In file included from fs/qnx4/qnx4.h:3,
from fs/qnx4/dir.c:16:
include/uapi/linux/qnx4_fs.h:45:25: note: source object declared here
45 | char di_fname[QNX4_SHORT_NAME_MAX];
| ^~~~~~~~
which is because the source code doesn't really make this whole "one of
two different types" explicit.
Fix this by introducing a very explicit union of the two types, and
basically explaining to the compiler what is really going on.

[ Upstream commit fc7c028dcdbfe981bca75d2a7b95f363eb691ef3 ]
The sparc mdesc code does pointer games with 'struct mdesc_hdr', but
didn't describe to the compiler how that header is then followed by the
data that the header describes.
As a result, gcc is now unhappy since it does stricter pointer range
tracking, and doesn't understand about how these things work. This
results in various errors like:
arch/sparc/kernel/mdesc.c: In function ‘mdesc_node_by_name’:
arch/sparc/kernel/mdesc.c:647:22: error: ‘strcmp’ reading 1 or more bytes from a region of size 0 [-Werror=stringop-overread]
647 | if (!strcmp(names + ep[ret].name_offset, name))
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
which are easily avoided by just describing 'struct mdesc_hdr' better,
and making the node_block() helper function look into that unsized
data[] that follows the header.
This makes the sparc64 build happy again at least for my cross-compiler
version (gcc version 11.2.1).

[ Upstream commit 4e28550829258f7dab97383acaa477bd724c0ff4 ]
ISCSI_NET_PARAM_IFACE_ENABLE belongs to enum iscsi_net_param instead of
iscsi_iface_param so move it to ISCSI_NET_PARAM. Otherwise, when we call
into the driver, we might not match and return that we don't want attr
visible in sysfs. Found in code review.

commit e8f69b16ee776da88589b5271e3f46020efc8f6c upstream.
If resource allocation and registration fail for a muxed tty device
(e.g. if there are no more minor numbers) the driver should not try to
deregister the never-registered (or already-deregistered) tty.
Fix up the error handling to avoid dereferencing a NULL pointer when
attempting to remove the character device.
