Subject: [PATCH 5.4 46/71] Revert "leds: lp5523: fix a missing check of return value of lp55xx_read"

From: Greg Kroah-Hartman <[email protected]>

commit 8d1beda5f11953ffe135a5213287f0b25b4da41b upstream.

This reverts commit 248b57015f35c94d4eae2fdd8c6febf5cd703900.

Because of recent interactions with developers from @umn.edu, all
commits from them have been recently re-reviewed to ensure if they were
correct or not.

Upon review, this commit was found to be incorrect for the reasons
below, so it must be reverted. It will be fixed up "correctly" in a
later kernel change.

The original commit does not properly unwind if there is an error
condition so it needs to be reverted at this point in time.

Subject: [PATCH 5.4 24/71] ALSA: bebob/oxfw: fix Kconfig entry for Mackie d.2 Pro

From: Takashi Sakamoto <[email protected]>

commit 0edabdfe89581669609eaac5f6a8d0ae6fe95e7f upstream.

Mackie d.2 has an extension card for IEEE 1394 communication, which uses
BridgeCo DM1000 ASIC. On the other hand, Mackie d.4 Pro has built-in
function for IEEE 1394 communication by Oxford Semiconductor OXFW971,
according to schematic diagram available in Mackie website. Although I
misunderstood that Mackie d.2 Pro would be also a model with OXFW971,
it's wrong. Mackie d.2 Pro is a model which includes the extension card
as factory settings.

This commit fixes entries in Kconfig and comment in ALSA OXFW driver.

Subject: [PATCH 5.4 42/71] dm snapshot: fix a crash when an origin has no snapshots

From: Mikulas Patocka <[email protected]>

commit 7ee06ddc4038f936b0d4459d37a7d4d844fb03db 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.

From: Daniel Cordova A <[email protected]>

commit c1b55029493879f5bd585ff79f326e71f0bc05e3 upstream.

The GU502 requires a few steps to make headset i/o works properly:
pincfg, verbs to unmute headphone out and callback to toggle output
between speakers and headphone using jack.

Subject: [PATCH 5.4 26/71] Revert "ALSA: sb8: add a check for request_region"

From: Greg Kroah-Hartman <[email protected]>

commit 94f88309f201821073f57ae6005caefa61bf7b7e upstream.

This reverts commit dcd0feac9bab901d5739de51b3f69840851f8919.

Because of recent interactions with developers from @umn.edu, all
commits from them have been recently re-reviewed to ensure if they were
correct or not.

Upon review, this commit was found to be incorrect for the reasons
below, so it must be reverted. It will be fixed up "correctly" in a
later kernel change.

The original commit message for this change was incorrect as the code
path can never result in a NULL dereference, alluding to the fact that
whatever tool was used to "find this" is broken. It's just an optional
resource reservation, so removing this check is fine.

Subject: [PATCH 5.4 28/71] ALSA: hda/realtek: reset eapd coeff to default value for alc287

From: Hui Wang <[email protected]>

commit 8822702f6e4c8917c83ba79e0ebf2c8c218910d4 upstream.

Ubuntu users reported an audio bug on the Lenovo Yoga Slim 7 14IIL05,
he installed dual OS (Windows + Linux), if he booted to the Linux
from Windows, the Speaker can't work well, it has crackling noise,
if he poweroff the machine first after Windows, the Speaker worked
well.

Before rebooting or shutdown from Windows, the Windows changes the
codec eapd coeff value, but the BIOS doesn't re-initialize its value,
when booting into the Linux from Windows, the eapd coeff value is not
correct. To fix it, set the codec default value to that coeff register
in the alsa driver.

From: Greg Kroah-Hartman <[email protected]>

This reverts commit 765976285a8c8db3f0eb7f033829a899d0c2786e.

Because of recent interactions with developers from @umn.edu, all
commits from them have been recently re-reviewed to ensure if they were
correct or not.

Upon review, this commit was found to be incorrect for the reasons
below, so it must be reverted. It will be fixed up "correctly" in a
later kernel change.

This commit is not correct, it should not have used unlikely() and is
not propagating the error properly to the calling function, so it should
be reverted at this point in time. Also, if the check failed, the
work queue was still assumed to be allocated, so further accesses would
have continued to fail, meaning this patch does nothing to solve the
root issues at all.

Subject: [PATCH 5.4 66/71] vgacon: Record video mode changes with VT_RESIZEX

From: Maciej W. Rozycki <[email protected]>

commit d4d0ad57b3865795c4cde2fb5094c594c2e8f469 upstream.

Fix an issue with VGA console font size changes made after the initial
video text mode has been changed with a user tool like `svgatextmode'
calling the VT_RESIZEX ioctl. As it stands in that case the original
screen geometry continues being used to validate further VT resizing.

Consequently when the video adapter is firstly reprogrammed from the
original say 80x25 text mode using a 9x16 character cell (720x400 pixel
resolution) to say 80x37 text mode and the same character cell (720x592
pixel resolution), and secondly the CRTC character cell updated to 9x8
(by loading a suitable font with the KD_FONT_OP_SET request of the
KDFONTOP ioctl), the VT geometry does not get further updated from 80x37
and only upper half of the screen is used for the VT, with the lower
half showing rubbish corresponding to whatever happens to be there in
the video memory that maps to that part of the screen. Of course the
proportions change according to text mode geometries and font sizes
chosen.

Address the problem then, by updating the text mode geometry defaults
rather than checking against them whenever the VT is resized via a user
ioctl.

Subject: [PATCH 5.4 67/71] vt: Fix character height handling with VT_RESIZEX

From: Maciej W. Rozycki <[email protected]>

commit 860dafa902595fb5f1d23bbcce1215188c3341e6 upstream.

Restore the original intent of the VT_RESIZEX ioctl's `v_clin' parameter
which is the number of pixel rows per character (cell) rather than the
height of the font used.

For framebuffer devices the two values are always the same, because the
former is inferred from the latter one. For VGA used as a true text
mode device these two parameters are independent from each other: the
number of pixel rows per character is set in the CRT controller, while
font height is in fact hardwired to 32 pixel rows and fonts of heights
below that value are handled by padding their data with blanks when
loaded to hardware for use by the character generator. One can change
the setting in the CRT controller and it will update the screen contents
accordingly regardless of the font loaded.

The `v_clin' parameter is used by the `vgacon' driver to set the height
of the character cell and then the cursor position within. Make the
parameter explicit then, by defining a new `vc_cell_height' struct
member of `vc_data', set it instead of `vc_font.height' from `v_clin' in
the VT_RESIZEX ioctl, and then use it throughout the `vgacon' driver
except where actual font data is accessed which as noted above is
independent from the CRTC setting.

This way the framebuffer console driver is free to ignore the `v_clin'
parameter as irrelevant, as it always should have, avoiding any issues
attempts to give the parameter a meaning there could have caused, such
as one that has led to commit 988d0763361b ("vt_ioctl: make VT_RESIZEX
behave like VT_RESIZE"):

"syzbot is reporting UAF/OOB read at bit_putcs()/soft_cursor() [1][2],
for vt_resizex() from ioctl(VT_RESIZEX) allows setting font height
larger than actual font height calculated by con_font_set() from
ioctl(PIO_FONT). Since fbcon_set_font() from con_font_set() allocates
minimal amount of memory based on actual font height calculated by
con_font_set(), use of vt_resizex() can cause UAF/OOB read for font
data."

The problem first appeared around Linux 2.5.66 which predates our repo
history, but the origin could be identified with the old MIPS/Linux repo
also at: <git://git.kernel.org/pub/scm/linux/kernel/git/ralf/linux.git>
as commit 9736a3546de7 ("Merge with Linux 2.5.66."), where VT_RESIZEX
code in `vt_ioctl' was updated as follows:

if (clin)
- video_font_height = clin;
+ vc->vc_font.height = clin;

making the parameter apply to framebuffer devices as well, perhaps due
to the use of "font" in the name of the original `video_font_height'
variable. Use "cell" in the new struct member then to avoid ambiguity.

Subject: [PATCH 5.4 70/71] ext4: fix error handling in ext4_end_enable_verity()

From: Eric Biggers <[email protected]>

commit f053cf7aa66cd9d592b0fc967f4d887c2abff1b7 upstream.

ext4 didn't properly clean up if verity failed to be enabled on a file:

- It left verity metadata (pages past EOF) in the page cache, which
would be exposed to userspace if the file was later extended.

- It didn't truncate the verity metadata at all (either from cache or
from disk) if an error occurred while setting the verity bit.

Fix these bugs by adding a call to truncate_inode_pages() and ensuring
that we truncate the verity metadata (both from cache and from disk) in
all error paths. Also rework the code to cleanly separate the success
path from the error paths, which makes it much easier to understand.

This reverts commit 63a06181d7ce169d09843645c50fea1901bc9f0a.

Because of recent interactions with developers from @umn.edu, all
commits from them have been recently re-reviewed to ensure if they were
correct or not.

Upon review, this commit was found to be incorrect for the reasons
below, so it must be reverted. It will be fixed up "correctly" in a
later kernel change.

The original commit is incorrect, it does not properly clean up on the
error path, so I'll keep the revert and fix it up properly with a
follow-on patch.

Subject: [PATCH 5.4 45/71] Revert "net: stmicro: fix a missing check of clk_prepare"

From: Greg Kroah-Hartman <[email protected]>

commit bee1b0511844c8c79fccf1f2b13472393b6b91f7 upstream.

This reverts commit f86a3b83833e7cfe558ca4d70b64ebc48903efec.

Because of recent interactions with developers from @umn.edu, all
commits from them have been recently re-reviewed to ensure if they were
correct or not.

Upon review, this commit was found to be incorrect for the reasons
below, so it must be reverted. It will be fixed up "correctly" in a
later kernel change.

The original commit causes a memory leak when it is trying to claim it
is properly handling errors. Revert this change and fix it up properly
in a follow-on commit.

Subject: [PATCH 5.4 69/71] nvme-multipath: fix double initialization of ANA state

From: Christoph Hellwig <[email protected]>

commit 5e1f689913a4498e3081093670ef9d85b2c60920 upstream.

nvme_init_identify and thus nvme_mpath_init can be called multiple
times and thus must not overwrite potentially initialized or in-use
fields. Split out a helper for the basic initialization when the
controller is initialized and make sure the init_identify path does
not blindly change in-use data structures.

This patch "looks" correct, but the driver keeps on running and will
fail horribly right afterward if this error condition ever trips.

So points for trying to resolve an issue, but a huge NEGATIVE value for
providing a "fake" fix for the problem as nothing actually got resolved
at all. I'll go fix this up properly...

Subject: [PATCH 5.4 58/71] ethernet: sun: niu: fix missing checks of niu_pci_eeprom_read()

From: Du Cheng <[email protected]>

commit e6e337708c22f80824b82d4af645f20715730ad0 upstream.

niu_pci_eeprom_read() may fail, so add checks to its return value and
propagate the error up the callstack.

An examination of the callstack up to niu_pci_eeprom_read shows that:

niu_pci_eeprom_read() // returns int
niu_pci_vpd_scan_props() // returns int
niu_pci_vpd_fetch() // returns *void*
niu_get_invariants() // returns int

since niu_pci_vpd_fetch() returns void which breaks the bubbling up,
change its return type to int so that error is propagated upwards.

Upon review, this commit was found to be incorrect for the reasons
below, so it must be reverted. It will be fixed up "correctly" in a

The change here was incorrect. While it is nice to check if
niu_pci_eeprom_read() succeeded or not when using the data, any error
that might have happened was not propagated upwards properly, causing
the kernel to assume that these reads were successful, which results in
invalid data in the buffer that was to contain the successfully read
data.

Move ufshcd_set_variant call in ufs_hisi_init_common to common error
section at end of the function, and then jump to this from the error
checking statements for both devm_reset_control_get and
ufs_hisi_get_resource. This fixes the original commit (63a06181d7ce)
which was reverted due to the University of Minnesota problems.

The original commit here, while technically correct, did not fully
handle all of the reported issues that the commit stated it was fixing,
so revert it until it can be "fixed" fully.

Note, ioremap() probably will never fail for old hardware like this, and
if anyone actually used this hardware (a PowerMac era PCI display card),
they would not be using fbdev anymore.

Upon review, this commit was found to be incorrect for the reasons

The original commit log for this change was incorrect, no "error
handling code" was added, things will blow up just as badly as before if
any of these cases ever were true. As this BUG_ON() never fired, and
most of these checks are "obviously" never going to be true, let's just
revert to the original code for now until this gets unwound to be done
correctly in the future.

From: Takashi Iwai <[email protected]>

commit e84749a78dc82bc545f12ce009e3dbcc2c5a8a91 upstream.

snd_usbmidi_get_ms_info() may access beyond the border when a
malformed descriptor is passed. This patch adds the sanity checks of
the given MS endpoint descriptors, and skips invalid ones.

Subject: [PATCH 5.4 65/71] video: hgafb: fix potential NULL pointer dereference

From: Igor Matheus Andrade Torrente <[email protected]>

commit dc13cac4862cc68ec74348a80b6942532b7735fa upstream.

The return of ioremap if not checked, and can lead to a NULL to be
assigned to hga_vram. Potentially leading to a NULL pointer
dereference.

The fix adds code to deal with this case in the error label and
changes how the hgafb_probe handles the return of hga_card_detect.

From: Greg Kroah-Hartman <[email protected]>

commit 9183f01b5e6e32eb3f17b5f3f8d5ad5ac9786c49 upstream.

As Peter points out, if we were to disconnect and then reconnect this
driver from a device, the "global" state of the device would contain odd
values and could cause problems. Fix this up by just initializing the
whole thing to 0 at probe() time.

Ideally this would be a per-device variable, but given the age and the
total lack of users of it, that would require a lot of s/./->/g changes
for really no good reason.

Subject: [PATCH 5.4 52/71] cdrom: gdrom: deallocate struct gdrom_unit fields in remove_gdrom

From: Atul Gopinathan <[email protected]>

commit d03d1021da6fe7f46efe9f2a7335564e7c9db5ab upstream.

The fields, "toc" and "cd_info", of "struct gdrom_unit gd" are allocated
in "probe_gdrom()". Prevent a memory leak by making sure "gd.cd_info" is
deallocated in the "remove_gdrom()" function.

Also prevent double free of the field "gd.toc" by moving it from the
module's exit function to "remove_gdrom()". This is because, in
"probe_gdrom()", the function makes sure to deallocate "gd.toc" in case
of any errors, so the exit function invoked later would again free
"gd.toc".

The patch also maintains consistency by deallocating the above mentioned
fields in "remove_gdrom()" along with another memory allocated field
"gd.disk".

just drop the extra memset happening here.

Subject: [PATCH 5.4 20/71] ALSA: line6: Fix racy initialization of LINE6 MIDI

From: Takashi Iwai <[email protected]>

commit 05ca447630334c323c9e2b788b61133ab75d60d3 upstream.

The initialization of MIDI devices that are found on some LINE6
drivers are currently done in a racy way; namely, the MIDI buffer
instance is allocated and initialized in each private_init callback
while the communication with the interface is already started via
line6_init_cap_control() call before that point. This may lead to
Oops in line6_data_received() when a spurious event is received, as
reported by syzkaller.

This patch moves the MIDI initialization to line6_init_cap_control()
as well instead of the too-lately-called private_init for avoiding the
race. Also this reduces slightly more lines, so it's a win-win
change.

From: Tom Seewald <[email protected]>

commit 84460f01cba382553199bc1361f69a872d5abed4 upstream.

The function qlcnic_dl_lb_test() currently calls netdev_alloc_skb()
without checking afterwards that the allocation succeeded. Fix this by
checking if the skb is NULL and returning an error in such a case.
Breaking out of the loop if the skb is NULL is not correct as no error
would be reported to the caller and no message would be printed for the
user.

commit a73b6a3b4109ce2ed01dbc51a6c1551a6431b53c upstream.

In commit b05ae01fdb89, someone tried to make the driver handle i2c read
errors by simply zeroing out the register contents, but for some reason
left unaltered the code that sets the cached register value the function
call return value.

The original patch was authored by a member of the Underhanded
Mangle-happy Nerds, I'm not terribly surprised. I don't have the
hardware anymore so I can't test this, but it seems like a pretty
obvious API usage fix to me...

From: Phillip Potter <[email protected]>

commit 6647f7a06eb030a2384ec71f0bb2e78854afabfe upstream.

Check return value of lp5xx_read and if non-zero, jump to code at end of
the function, causing lp5523_stop_all_engines to be executed before
returning the error value up the call chain. This fixes the original
commit (248b57015f35) which was reverted due to the University of Minnesota
problems.

This patch was later fixed with commit commit e181811bd04d ("nvmet: use
new ana_log_size instead the old one").

Build results:
total: 157 pass: 157 fail: 0
Qemu test results:
total: 428 pass: 427 fail: 1
Failed tests:
riscv:virt:defconfig:net,usb-ohci:nvme:rootfs

The failure is persistent; it manifests itself in failure to reboot.
The test passes after applying commit e181811bd04d ("nvmet: use new
ana_log_size instead the old one").

Argh, I thought I ran my script to catch these, I wonder what went
wrong.

Hm, my script caught it, no idea how I missed it on my end, my fault.
Thanks for pointing this out, now queued up.
