commit 6f3353c2d2b3eb4de52e9704cb962712033db181 upstream.
Current ebpf disassembly buffer size of 64 is too small. E.g. this line takes 65 bytes: 01fffff8005822e: ec8100ed8065\tclgrj\t%r8,%r1,8,001fffff80058408\n\0
Double the buffer size like it is done for the kernel disassembly buffer.
Fixes the following KASAN finding:

commit e483bb9a991bdae29a0caa4b3a6d002c968f94aa upstream.
In cm_write(), buf is always freed when reaching the end of the function. If the requested count is less than table.length, the allocated buffer will be freed but subsequent calls to cm_write() will still try to access it.
Remove the unconditional kfree(buf) at the end of the function and set the buf to NULL in the -EINVAL error path to match the rest of function.

commit 1cfd8956437f842836e8a066b40d1ec2fc01f13e upstream.
In cm_write(), if the 'buf' is allocated memory but not fully consumed, it is possible to reallocate the buffer without freeing it by passing '*ppos' as 0 on a subsequent call.
Add an explicit kfree() before kzalloc() to prevent the possible memory leak.

commit 8c9af478c06bb1ab1422f90d8ecbc53defd44bc3 upstream.
# echo switch_mm:traceoff > /sys/kernel/tracing/set_ftrace_filter
will cause switch_mm to stop tracing by the traceoff command.
# echo -n switch_mm:traceoff > /sys/kernel/tracing/set_ftrace_filter
does nothing.
The reason is that the parsing in the write function only processes commands if it finished parsing (there is white space written after the command). That's to handle:
write(fd, "switch_mm:", 10); write(fd, "traceoff", 8);
cases, where the command is broken over multiple writes.
The problem is if the file descriptor is closed, then the write call is not processed, and the command needs to be processed in the release code. The release code can handle matching of functions, but does not handle commands.

commit c4e792d1acce31c2eb7b9193ab06ab94de05bf42 upstream.
The LLVM ld.lld linker uses a different symbol type for __bss_start, resulting in the calculation of KBSS_SZ to be thrown off. Up until now, this has gone unnoticed as it only affects the appended DTB case, but pending changes for ARM in the way the decompressed kernel is cleaned from the caches has uncovered this problem.
On a ld.lld build:
$ nm vmlinux |grep bss_ c1c22034 D __bss_start c1c86e98 B __bss_stop
resulting in
$ readelf -s arch/arm/boot/compressed/vmlinux | grep bss_size 433: c1c86e98 0 NOTYPE GLOBAL DEFAULT ABS _kernel_bss_size
which is obviously incorrect, and may cause the cache clean to access unmapped memory, or cause the size calculation to wrap, resulting in no cache clean to be performed at all.

commit 97fce126e279690105ee15be652b465fd96f9997 upstream.
In command queueing mode, the cache isn't flushed via the mmc_flush_cache() function, but instead by issuing a CMDQ_TASK_MGMT (CMD48) with a FLUSH_CACHE opcode. In this path, we need to check if cache has been enabled, before deciding to flush the cache, along the lines of what's being done in mmc_flush_cache().
To fix this problem, let's add a new bus ops callback ->cache_enabled() and implement it for the mmc bus type. In this way, the mmc block device driver can call it to know whether cache flushing should be done.

commit 147186f531ae49c18b7a9091a2c40e83b3d95649 upstream.
A CMD11 is sent to the SD/SDIO card to start the voltage switch procedure into 1.8V I/O. According to the SD spec a power cycle is needed of the card, if it turns out that the CMD11 fails. Let's fix this, to allow a retry of the initialization without the voltage switch, to succeed.
Note that, whether it makes sense to also retry with the voltage switch after the power cycle is a bit more difficult to know. At this point, we treat it like the CMD11 isn't supported and therefore we skip it when retrying.

commit 67addf29004c5be9fa0383c82a364bb59afc7f84 upstream.
When creating a subvolume we allocate an extent buffer for its root node after starting a transaction. We setup a root item for the subvolume that points to that extent buffer and then attempt to insert the root item into the root tree - however if that fails, due to ENOMEM for example, we do not free the extent buffer previously allocated and we do not abort the transaction (as at that point we did nothing that can not be undone).
This means that we effectively do not return the metadata extent back to the free space cache/tree and we leave a delayed reference for it which causes a metadata extent item to be added to the extent tree, in the next transaction commit, without having backreferences. When this happens 'btrfs check' reports the following:
$ btrfs check /dev/sdi Opening filesystem to check... Checking filesystem on /dev/sdi UUID: dce2cb9d-025f-4b05-a4bf-cee0ad3785eb [1/7] checking root items [2/7] checking extents ref mismatch on [30425088 16384] extent item 1, found 0 backref 30425088 root 256 not referenced back 0x564a91c23d70 incorrect global backref count on 30425088 found 1 wanted 0 backpointer mismatch on [30425088 16384] owner ref check failed [30425088 16384] ERROR: errors found in extent allocation tree or chunk allocation [3/7] checking free space cache [4/7] checking fs roots [5/7] checking only csums items (without verifying data) [6/7] checking root refs [7/7] checking quota groups skipped (not enabled on this FS) found 212992 bytes used, error(s) found total csum bytes: 0 total tree bytes: 131072 total fs tree bytes: 32768 total extent tree bytes: 16384 btree space waste bytes: 124669 file data blocks allocated: 65536 referenced 65536
So fix this by freeing the metadata extent if btrfs_insert_root() returns an error.

Patch adds extra checking for bInterval passed by configfs. The 5.6.4 chapter of USB Specification (rev. 2.0) say: "A high-bandwidth endpoint must specify a period of 1x125 µs (i.e., a bInterval value of 1)."
The issue was observed during testing UVC class on CV. I treat this change as improvement because we can control bInterval by configfs.

When irq_matrix_free() is called for an unallocated vector the managed_allocated and total_allocated counters get out of sync with the real state of the matrix. Later, when the last interrupt is freed, these counters will underflow resulting in UINTMAX because the counters are unsigned.
While this is certainly a problem of the calling code, this can be catched in the allocator by checking the allocation bit for the to be freed vector which simplifies debugging.
An example of the problem described above: https://lore.kernel.org/lkml/20210318192819.636943062@linutronix.de/

Currently user can configure UAC1 function with parameters that violate UAC1 spec or are not supported by UAC1 gadget implementation.
This can lead to incorrect behavior if such gadget is connected to the host - like enumeration failure or other issues depending on host's UAC1 driver implementation, bringing user to a long hours of debugging the issue.
Instead of silently accept these parameters, throw an error if they are not valid.

The current dwc3_gadget_reset_interrupt() will stop any active transfers, but only addresses blocking of EP queuing for while we are coming from a disconnected scenario, i.e. after receiving the disconnect event. If the host decides to issue a bus reset on the device, the connected parameter will still be set to true, allowing for EP queuing to continue while we are disabling the functions. To avoid this, set the connected flag to false until the stop active transfers is complete.

Some hosts incorrectly use sub-minor version for minor version (i.e. 0x02 instead of 0x20 for bcdUSB 0x320 and 0x01 for bcdUSB 0x310). Currently the xHCI driver works around this by just checking for minor revision > 0x01 for USB 3.1 everywhere. With the addition of USB 3.2, checking this gets a bit cumbersome. Since there is no USB release with bcdUSB 0x301 to 0x309, we can assume that sub-minor version 01 to 09 is incorrect. Let's try to fix this and use the minor revision that matches with the USB/xHCI spec to help with the version checking within the driver.

[ Upstream commit 4514d991d99211f225d83b7e640285f29f0755d0 ]
It should not be necessary to update the current_state field of struct pci_dev in pci_enable_device_flags() before calling do_pci_enable_device() for the device, because none of the code between that point and the pci_set_power_state() call in do_pci_enable_device() invoked later depends on it.
Moreover, doing that is actively harmful in some cases. For example, if the given PCI device depends on an ACPI power resource whose _STA method initially returns 0 ("off"), but the config space of the PCI device is accessible and the power state retrieved from the PCI_PM_CTRL register is D0, the current_state field in the struct pci_dev representing that device will get out of sync with the power.state of its ACPI companion object and that will lead to power management issues going forward.
To avoid such issues it is better to leave the current_state value as is until it is changed to PCI_D0 by do_pci_enable_device() as appropriate. However, the power state of the device is not changed to PCI_D0 if it is already enabled when pci_enable_device_flags() gets called for it, so update its current_state in that case, but use pci_update_current_state() covering platform PM too for that.

[ Upstream commit 8abe7fc26ad8f28bfdf78adbed56acd1fa93f82d ]
When cross-compiling with Clang, the `$(CLANG_FLAGS)' variable contains additional flags needed to build C and assembly sources for the target platform. Normally this variable is automatically included in `$(KBUILD_CFLAGS)' via the top-level Makefile.
The x86 real-mode makefile builds `$(REALMODE_CFLAGS)' from a plain assignment and therefore drops the Clang flags. This causes Clang to not recognize x86-specific assembler directives:
arch/x86/realmode/rm/header.S:36:1: error: unknown directive .type real_mode_header STT_OBJECT ; .size real_mode_header, .-real_mode_header ^
Explicit propagation of `$(CLANG_FLAGS)' to `$(REALMODE_CFLAGS)', which is inherited by real-mode make rules, fixes cross-compilation with Clang for x86 targets.
Relevant flags:
* `--target' sets the target architecture when cross-compiling. This flag must be set for both compilation and assembly (`KBUILD_AFLAGS') to support architecture-specific assembler directives.
* `-no-integrated-as' tells clang to assemble with GNU Assembler instead of its built-in LLVM assembler. This flag is set by default unless `LLVM_IAS=1' is set, because the LLVM assembler can't yet parse certain GNU extensions.

When Secure World returns, it may have changed the size attribute of the memory references passed as [in/out] parameters. The GlobalPlatform TEE Internal Core API specification does not restrict the values that this size can take. In particular, Secure World may increase the value to be larger than the size of the input buffer to indicate that it needs more.
Therefore, the size check in optee_from_msg_param() is incorrect and needs to be removed. This fixes a number of failed test cases in the GlobalPlatform TEE Initial Configuratiom Test Suite v2_0_0_0-2017_06_09 when OP-TEE is compiled without dynamic shared memory support (CFG_CORE_DYN_SHM=n).

This driver's remove path calls cancel_delayed_work(). However, that function does not wait until the work function finishes. This means that the callback function may still be running after the driver's remove function has finished, which would result in a use-after-free.

A few BUG_ON()'s in replace_path are purely to keep us from making logical mistakes, so replace them with ASSERT()'s.

On a pt2pt setup, between 2 initiators, if one side issues a a LOGO, there is no relogin attempt. The FC specs are grey in this area on which port (higher wwn or not) is to re-login.
As there is no spec guidance, unconditionally re-PLOGI after the logout to ensure a login is re-established.

On all newer bq27xxx ICs, the AveragePower register contains a signed value; in addition to handling the raw value as unsigned, the driver code also didn't convert it to µW as expected.
At least for the BQ28Z610, the reference manual incorrectly states that the value is in units of 1mW and not 10mW. I have no way of knowing whether the manuals of other supported ICs contain the same error, or if there are models that actually use 1mW. At least, the new code shouldn't be *less* correct than the old version for any device.
power_avg is removed from the cache structure, se we don't have to extend it to store both a signed value and an error code. Always getting an up-to-date value may be desirable anyways, as it avoids inconsistent current and power readings when switching between charging and discharging.

When the jack is partially inserted and then removed again it may be removed while the hpdet code is running. In this case the following may happen:
1. The "JACKDET rise" or ""JACKDET fall" IRQ triggers 2. arizona_jackdet runs and takes info->lock 3. The "HPDET" IRQ triggers 4. arizona_hpdet_irq runs, blocks on info->lock 5. arizona_jackdet calls arizona_stop_mic() and clears info->hpdet_done 6. arizona_jackdet releases info->lock 7. arizona_hpdet_irq now can continue running and: 7.1 Calls arizona_start_mic() (if a mic was detected) 7.2 sets info->hpdet_done
Step 7 is undesirable / a bug: 7.1 causes the device to stay in a high power-state (with MICVDD enabled) 7.2 causes hpdet to not run on the next jack insertion, which in turn causes the EXTCON_JACK_HEADPHONE state to never get set
This fixes both issues by skipping these 2 steps when arizona_hpdet_irq runs after the jack has been unplugged.

On bsg command completion, bsg_job_done() was called while qla driver continued to access the bsg_job buffer. bsg_job_done() would free up resources that ended up being reused by other task while the driver continued to access the buffers. As a result, driver was reading garbage data.

If some error occurs, URB buffers should also be freed. If they aren't freed with the dvb here, the em28xx_dvb_fini call doesn't frees the URB buffers as dvb is set to NULL. The function in which error occurs should do all the cleanup for the allocations it had done.
Tested the patch with the reproducer provided by syzbot. This patch fixes the memleak.

This driver's remove path calls cancel_delayed_work(). However, that function does not wait until the work function finishes. This means that the callback function may still be running after the driver's remove function has finished, which would result in a use-after-free.
Fix by calling cancel_delayed_work_sync(), which ensures that the work is properly cancelled, no longer running, and unable to re-schedule itself.

syzbot reported memory leak in dvb-usb. The problem was in invalid error handling in dvb_usb_adapter_init().
for (n = 0; n < d->props.num_adapters; n++) { .... if ((ret = dvb_usb_adapter_stream_init(adap)) || (ret = dvb_usb_adapter_dvb_init(adap, adapter_nrs)) || (ret = dvb_usb_adapter_frontend_init(adap))) { return ret; } ... d->num_adapters_initialized++; ... }
In case of error in dvb_usb_adapter_dvb_init() or dvb_usb_adapter_dvb_init() d->num_adapters_initialized won't be incremented, but dvb_usb_adapter_exit() relies on it:
for (n = 0; n < d->num_adapters_initialized; n++)
So, allocated objects won't be freed.

For two of the supported sensors the stv06xx driver allocates memory which is stored in sd->sensor_priv. This memory is freed on a disconnect, but if the probe() fails, then it isn't freed and so this leaks memory.
Add a new probe_error() op that drivers can use to free any allocated memory in case there was a probe failure.
Thanks to Pavel Skripkin paskripkin@gmail.com for discovering the cause of the memory leak.

Leaving this at a close-to-maximum register value 0xFFF0 means it takes very long for the MDSS to generate a software vsync interrupt when the hardware TE interrupt doesn't arrive. Configuring this to double the vtotal (like some downstream kernels) leads to a frame to take at most twice before the vsync signal, until hardware TE comes up.
In this case the hardware interrupt responsible for providing this signal - "disp-te" gpio - is not hooked up to the mdp5 vsync/pp logic at all. This solves severe panel update issues observed on at least the Xperia Loire and Tone series, until said gpio is properly hooked up to an irq.

Fix a crash caused by a double put on the node when the driver completed an ACC for an unsolicted abort on the same node. The second put was executed by lpfc_nlp_not_used() and is wrong because the completion routine executes the nlp_put when the iocbq was released. Additionally, the driver is issuing a LOGO then immediately calls lpfc_nlp_set_state to put the node into NPR. This call does nothing.
Remove the lpfc_nlp_not_used call and additional set_state in the completion routine. Remove the lpfc_nlp_set_state post issue_logo. Isn't necessary.

[ Upstream commit 28096067686c5a5cbd4c35b079749bd805df5010 ]
A review of the code showed, that this function which is exposed within the whole kernel should do a parameter check for the amount of bytes requested. If this requested bytes is too high an unsigned int overflow could happen causing this function to try to memcpy a really big memory chunk.
This is not a security issue as there are only two invocations of this function from arch/s390/include/asm/archrandom.h and both are not exposed to userland.

commit 1c98f574403dbcf2eb832d5535a10d967333ef2d upstream.
Our code analyzer reported a uaf.
In snd_emu8000_create_mixer, the callee snd_ctl_add(..,emu->controls[i]) calls snd_ctl_add_replace(.., kcontrol,..). Inside snd_ctl_add_replace(), if error happens, kcontrol will be freed by snd_ctl_free_one(kcontrol). Then emu->controls[i] points to a freed memory, and the execution comes to __error branch of snd_emu8000_create_mixer. The freed emu->controls[i] is used in snd_ctl_remove(card, emu->controls[i]).
My patch set emu->controls[i] to NULL if snd_ctl_add() failed to avoid the uaf.

Just re-order the cx5066_fixups[] entries for HP devices for avoiding the oversight of the duplicated or unapplied item in future. No functional changes.

commit 4fb44dd2c1dda18606348acdfdb97e8759dde9df upstream.
In snd_sb_qsound_build, snd_ctl_add(..,p->qsound_switch...) and snd_ctl_add(..,p->qsound_space..) are called. But the second arguments of snd_ctl_add() could be freed via snd_ctl_add_replace() ->snd_ctl_free_one(). After the error code is returned, snd_sb_qsound_destroy(p) is called in __error branch.
But in snd_sb_qsound_destroy(), the freed p->qsound_switch and p->qsound_space are still used by snd_ctl_remove().
My patch set p->qsound_switch and p->qsound_space to NULL if snd_ctl_add() failed to avoid the uaf bugs. But these codes need to further be improved with the code style.

commit d2e8f641257d0d3af6e45d6ac2d6f9d56b8ea964 upstream.
In the current code, we have some assumption that the audio clock selector has been set up implicitly and don't want to touch it unless it's really needed for the fallback autoclock setup. This works for most devices but some seem having a problem. Partially this was covered for the devices with a single connector at the initialization phase (commit 086b957cc17f "ALSA: usb-audio: Skip the clock selector inquiry for single connections"), but also there are cases where the wrong clock set up is kept silently. The latter seems to be the cause of the noises on Behringer devices.
In this patch, we explicitly set up the audio clock selector whenever the appropriate node is found.

commit a01df925d1bbc97d6f7fe07b157aadb565315337 upstream.
Apply const prefix to the remaining places: the static table for the unit information, the mixer maps, the validator tables, etc.
Just for minor optimization and no functional changes.

The decibel volume range contains a negative maximum value resulting in pipewire complaining about the device and effectivly having no sound output. The wrong values also resulted in the headset sounding muted already at a mixer level of about ~25%.

[ Upstream commit f9690f426b2134cc3e74bfc5d9dfd6a4b2ca5281 ]
Commit dbcc7d57bffc0c ("btrfs: fix race when cloning extent buffer during rewind of an old root"), fixed a race when we need to rewind the extent buffer of an old root. It was caused by picking a new mod log operation for the extent buffer while getting a cloned extent buffer with an outdated number of items (off by -1), because we cloned the extent buffer without locking it first.
However there is still another similar race, but in the opposite direction. The cloned extent buffer has a number of items that does not match the number of tree mod log operations that are going to be replayed. This is because right after we got the last (most recent) tree mod log operation to replay and before locking and cloning the extent buffer, another task adds a new pointer to the extent buffer, which results in adding a new tree mod log operation and incrementing the number of items in the extent buffer. So after cloning we have mismatch between the number of items in the extent buffer and the number of mod log operations we are going to apply to it. This results in hitting a BUG_ON() that produces the following stack trace:

The following steps explain in more detail how it happens:
1) We have one tree mod log user (through fiemap or the logical ino ioctl), with a sequence number of 1, so we have fs_info->tree_mod_seq == 1. This is task A;
2) Another task is at ctree.c:balance_level() and we have eb X currently as the root of the tree, and we promote its single child, eb Y, as the new root.
Then, at ctree.c:balance_level(), we call:
ret = btrfs_tree_mod_log_insert_root(root->node, child, true);
3) At btrfs_tree_mod_log_insert_root() we create a tree mod log operation of type BTRFS_MOD_LOG_KEY_REMOVE_WHILE_FREEING, with a ->logical field pointing to ebX->start. We only have one item in eb X, so we create only one tree mod log operation, and store in the "tm_list" array;
4) Then, still at btrfs_tree_mod_log_insert_root(), we create a tree mod log element of operation type BTRFS_MOD_LOG_ROOT_REPLACE, ->logical set to ebY->start, ->old_root.logical set to ebX->start, ->old_root.level set to the level of eb X and ->generation set to the generation of eb X;
5) Then btrfs_tree_mod_log_insert_root() calls tree_mod_log_free_eb() with "tm_list" as argument. After that, tree_mod_log_free_eb() calls tree_mod_log_insert(). This inserts the mod log operation of type BTRFS_MOD_LOG_KEY_REMOVE_WHILE_FREEING from step 3 into the rbtree with a sequence number of 2 (and fs_info->tree_mod_seq set to 2);
6) Then, after inserting the "tm_list" single element into the tree mod log rbtree, the BTRFS_MOD_LOG_ROOT_REPLACE element is inserted, which gets the sequence number 3 (and fs_info->tree_mod_seq set to 3);
7) Back to ctree.c:balance_level(), we free eb X by calling btrfs_free_tree_block() on it. Because eb X was created in the current transaction, has no other references and writeback did not happen for it, we add it back to the free space cache/tree;
8) Later some other task B allocates the metadata extent from eb X, since it is marked as free space in the space cache/tree, and uses it as a node for some other btree;
9) The tree mod log user task calls btrfs_search_old_slot(), which calls btrfs_get_old_root(), and finally that calls tree_mod_log_oldest_root() with time_seq == 1 and eb_root == eb Y;
10) The first iteration of the while loop finds the tree mod log element with sequence number 3, for the logical address of eb Y and of type BTRFS_MOD_LOG_ROOT_REPLACE;
11) Because the operation type is BTRFS_MOD_LOG_ROOT_REPLACE, we don't break out of the loop, and set root_logical to point to tm->old_root.logical, which corresponds to the logical address of eb X;
12) On the next iteration of the while loop, the call to tree_mod_log_search_oldest() returns the smallest tree mod log element for the logical address of eb X, which has a sequence number of 2, an operation type of BTRFS_MOD_LOG_KEY_REMOVE_WHILE_FREEING and corresponds to the old slot 0 of eb X (eb X had only 1 item in it before being freed at step 7);
13) We then break out of the while loop and return the tree mod log operation of type BTRFS_MOD_LOG_ROOT_REPLACE (eb Y), and not the one for slot 0 of eb X, to btrfs_get_old_root();
14) At btrfs_get_old_root(), we process the BTRFS_MOD_LOG_ROOT_REPLACE operation and set "logical" to the logical address of eb X, which was the old root. We then call tree_mod_log_search() passing it the logical address of eb X and time_seq == 1;
15) But before calling tree_mod_log_search(), task B locks eb X, adds a key to eb X, which results in adding a tree mod log operation of type BTRFS_MOD_LOG_KEY_ADD, with a sequence number of 4, to the tree mod log, and increments the number of items in eb X from 0 to 1. Now fs_info->tree_mod_seq has a value of 4;
16) Task A then calls tree_mod_log_search(), which returns the most recent tree mod log operation for eb X, which is the one just added by task B at the previous step, with a sequence number of 4, a type of BTRFS_MOD_LOG_KEY_ADD and for slot 0;
17) Before task A locks and clones eb X, task A adds another key to eb X, which results in adding a new BTRFS_MOD_LOG_KEY_ADD mod log operation, with a sequence number of 5, for slot 1 of eb X, increments the number of items in eb X from 1 to 2, and unlocks eb X. Now fs_info->tree_mod_seq has a value of 5;
18) Task A then locks eb X and clones it. The clone has a value of 2 for the number of items and the pointer "tm" points to the tree mod log operation with sequence number 4, not the most recent one with a sequence number of 5, so there is mismatch between the number of mod log operations that are going to be applied to the cloned version of eb X and the number of items in the clone;
19) Task A then calls tree_mod_log_rewind() with the clone of eb X, the tree mod log operation with sequence number 4 and a type of BTRFS_MOD_LOG_KEY_ADD, and time_seq == 1;
20) At tree_mod_log_rewind(), we set the local variable "n" with a value of 2, which is the number of items in the clone of eb X.
Then in the first iteration of the while loop, we process the mod log operation with sequence number 4, which is targeted at slot 0 and has a type of BTRFS_MOD_LOG_KEY_ADD. This results in decrementing "n" from 2 to 1.
Then we pick the next tree mod log operation for eb X, which is the tree mod log operation with a sequence number of 2, a type of BTRFS_MOD_LOG_KEY_REMOVE_WHILE_FREEING and for slot 0, it is the one added in step 5 to the tree mod log tree.
We go back to the top of the loop to process this mod log operation, and because its slot is 0 and "n" has a value of 1, we hit the BUG_ON:
(...) switch (tm->op) { case BTRFS_MOD_LOG_KEY_REMOVE_WHILE_FREEING: BUG_ON(tm->slot < n); fallthrough; (...)
Fix this by checking for a more recent tree mod log operation after locking and cloning the extent buffer of the old root node, and use it as the first operation to apply to the cloned extent buffer when rewinding it.
Stable backport notes: due to moved code and renames, in =< 5.11 the change should be applied to ctree.c:get_old_root.

[ Upstream commit 388708028e6937f3fc5fc19aeeb847f8970f489c ]
The arm64 assembler in binutils 2.32 and above generates a program property note in a note section, .note.gnu.property, to encode used x86 ISAs and features. But the kernel linker script only contains a single NOTE segment:
PHDRS { text PT_LOAD FLAGS(5) FILEHDR PHDRS; /* PF_R|PF_X */ dynamic PT_DYNAMIC FLAGS(4); /* PF_R */ note PT_NOTE FLAGS(4); /* PF_R */ }
The NOTE segment generated by the vDSO linker script is aligned to 4 bytes. But the .note.gnu.property section must be aligned to 8 bytes on arm64.
$ readelf -n vdso64.so
Displaying notes found in: .note Owner Data size Description Linux 0x00000004 Unknown note type: (0x00000000) description data: 06 00 00 00 readelf: Warning: note with invalid namesz and/or descsz found at offset 0x20 readelf: Warning: type: 0x78, namesize: 0x00000100, descsize: 0x756e694c, alignment: 8
Since the note.gnu.property section in the vDSO is not checked by the dynamic linker, discard the .note.gnu.property sections in the vDSO.
Similar to commit 4caffe6a28d31 ("x86/vdso: Discard .note.gnu.property sections in vDSO"), but for arm64.

commit 3e903315790baf4a966436e7f32e9c97864570ac upstream.
Conside the following case, it just write a big file into flash, when complete writing, delete the file, and then power off promptly. Next time power on, we'll get a replay list like: ... LEB 1105:211344 len 4144 deletion 0 sqnum 428783 key type 1 inode 80 LEB 15:233544 len 160 deletion 1 sqnum 428785 key type 0 inode 80 LEB 1105:215488 len 4144 deletion 0 sqnum 428787 key type 1 inode 80 ... In the replay list, data nodes' deletion are 0, and the inode node's deletion is 1. In current logic, the file's dentry will be removed, but inode and the flash space it occupied will be reserved. User will see that much free space been disappeared.
We only need to check the deletion value of the following inode type node of the replay entry.

The root cause is, if nat entry in checkpoint journal area is corrupted, e.g. nid of journalled nat entry exceeds max nid value, during checkpoint, once it tries to flush nat journal to NAT area, get_next_nat_page() may access out-of-bounds memory on nat_bitmap due to it uses wrong nid value as bitmap offset.

commit cbaf3f6af9c268caf558c8e7ec52bcb35c5455dd upstream.
Each multicast route that is forwarding packets (as opposed to trapping them) points to a list of egress router interfaces (RIFs) through which packets are replicated.
A route's action can transition from trap to forward when a RIF is created for one of the route's egress virtual interfaces (eVIF). When this happens, the route's action is first updated and only later the list of egress RIFs is committed to the device.
This results in the route pointing to an invalid list. In case the list pointer is out of range (due to uninitialized memory), the device will complain:
mlxsw_spectrum2 0000:06:00.0: EMAD reg access failed (tid=5733bf490000905c,reg_id=300f(pefa),type=write,status=7(bad parameter))
Fix this by first committing the list of egress RIFs to the device and only later update the route's action.
Note that a fix is not needed in the reverse function (i.e., mlxsw_sp_mr_route_evif_unresolve()), as there the route's action is first updated and only later the RIF is removed from the list.

for IPv4 packets, ovs_fragment() uses a temporary struct dst_entry. Then, in the following call graph:
ip_do_fragment() ip_skb_dst_mtu() ip_dst_mtu_maybe_forward() ip_mtu_locked()
the pointer to struct dst_entry is used as pointer to struct rtable: this turns the access to struct members like rt_mtu_locked into an OOB read in the stack. Fix this changing the temporary variable used for IPv4 packets in ovs_fragment(), similarly to what is done for IPv6 few lines below.

commit 1ecd5b129252249b9bc03d7645a7bda512747277 upstream.
When failing the driver probe because of invalid firmware properties, the GTDT driver unmaps the interrupt that it mapped earlier.
However, it never checks whether the mapping of the interrupt actially succeeded. Even more, should the firmware report an illegal interrupt number that overlaps with the GIC SGI range, this can result in an IPI being unmapped, and subsequent fireworks (as reported by Dann Frazier).
Rework the driver to have a slightly saner behaviour and actually check whether the interrupt has been mapped before unmapping things.

commit 5ae5bc12d0728db60a0aa9b62160ffc038875f1a upstream.
During the EEH MMIO error checking, the current implementation fails to map the (virtual) MMIO address back to the pci device on radix with hugepage mappings for I/O. This results into failure to dispatch EEH event with no recovery even when EEH capability has been enabled on the device.
eeh_check_failure(token) # token = virtual MMIO address addr = eeh_token_to_phys(token); edev = eeh_addr_cache_get_dev(addr); if (!edev) return 0; eeh_dev_check_failure(edev); <= Dispatch the EEH event
In case of hugepage mappings, eeh_token_to_phys() has a bug in virt -> phys translation that results in wrong physical address, which is then passed to eeh_addr_cache_get_dev() to match it against cached pci I/O address ranges to get to a PCI device. Hence, it fails to find a match and the EEH event never gets dispatched leaving the device in failed state.
The commit 33439620680be ("powerpc/eeh: Handle hugepages in ioremap space") introduced following logic to translate virt to phys for hugepage mappings:
eeh_token_to_phys(): + pa = pte_pfn(*ptep); + + /* On radix we can do hugepage mappings for io, so handle that */ + if (hugepage_shift) { + pa <<= hugepage_shift; <= This is wrong + pa |= token & ((1ul << hugepage_shift) - 1); + }
This patch fixes the virt -> phys translation in eeh_token_to_phys() function.

commit 7de21e679e6a789f3729e8402bc440b623a28eae upstream.
A few archs like powerpc have different errno.h values for macros EDEADLOCK and EDEADLK. In code including both libc and linux versions of errno.h, this can result in multiple definitions of EDEADLOCK in the include chain. Definitions to the same value (e.g. seen with mips) do not raise warnings, but on powerpc there are redefinitions changing the value, which raise warnings and errors (if using "-Werror").
Guard against these redefinitions to avoid build errors like the following, first seen cross-compiling libbpf v5.8.9 for powerpc using GCC 8.4.0 with musl 1.1.24:
In file included from ../../arch/powerpc/include/uapi/asm/errno.h:5, from ../../include/linux/err.h:8, from libbpf.c:29: ../../include/uapi/asm-generic/errno.h:40: error: "EDEADLOCK" redefined [-Werror] #define EDEADLOCK EDEADLK

This patch addresses a data corruption bug in raid1 arrays using bitmaps. Without this fix, the bitmap bits for the failed I/O end up being cleared.
Since we are in the failure leg of raid1_end_write_request, the request either needs to be retried (R1BIO_WriteError) or failed (R1BIO_Degraded).

1. the MD sync thread calls end_reshape() from raid5_sync_request() when done reshaping. However end_reshape() _only_ updates the reshape position to MaxSector keeping the changed layout configuration though (i.e. any delta disks, chunk sector or RAID algorithm changes). That inconclusive configuration is stored in the superblock.
2. dm-raid constructs a mapping, loading named inconsistent superblock as of step 1 before step 3 is able to finish resetting the reshape state completely, and calls md_run() which leads to mentioned bug in raid5.c.
3. the MD RAID personality's finish_reshape() is called; which resets the reshape information on chunk sectors, delta disks, etc. This explains why the bug is rarely seen on multi-core machines, as MD's finish_reshape() superblock update races with the dm-raid constructor's superblock load in step 2.
Fix identifies inconclusive superblock content in the dm-raid constructor and resets it before calling md_run(), factoring out identifying checks into rs_is_layout_change() to share in existing rs_reshape_requested() and new rs_reset_inclonclusive_reshape(). Also enhance a comment and remove an empty line.

commit 82e5d8cc768b0c7b03c551a9ab1f8f3f68d5f83f upstream.
gcc-11 introdces a harmless warning for cap_inode_getsecurity:
security/commoncap.c: In function ‘cap_inode_getsecurity’: security/commoncap.c:440:33: error: ‘memcpy’ reading 16 bytes from a region of size 0 [-Werror=stringop-overread] 440 | memcpy(&nscap->data, &cap->data, sizeof(__le32) * 2 * VFS_CAP_U32); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The problem here is that tmpbuf is initialized to NULL, so gcc assumes it is not accessible unless it gets set by vfs_getxattr_alloc(). This is a legitimate warning as far as I can tell, but the code is correct since it correctly handles the error when that function fails.
Add a separate NULL check to tell gcc about it as well.

commit e7c6e405e171fb33990a12ecfd14e6500d9e5cf2 upstream.
It seems like Fedora 34 ends up enabling a few new gcc warnings, notably "-Wstringop-overread" and "-Warray-parameter".
Both of them cause what seem to be valid warnings in the kernel, where we have array size mismatches in function arguments (that are no longer just silently converted to a pointer to element, but actually checked).
This fixes most of the trivial ones, by making the function declaration match the function definition, and in the case of intel_pm.c, removing the over-specified array size from the argument declaration.
At least one 'stringop-overread' warning remains in the i915 driver, but that one doesn't have the same obvious trivial fix, and may or may not actually be indicative of a bug.
[ It was a mistake to upgrade one of my machines to Fedora 34 while being busy with the merge window, but if this is the extent of the compiler upgrade problems, things are better than usual - Linus ]

commit 4fbf5d6837bf81fd7a27d771358f4ee6c4f243f8 upstream.
The FUTEX_WAIT operand has historically a relative timeout which means that the clock id is irrelevant as relative timeouts on CLOCK_REALTIME are not subject to wall clock changes and therefore are mapped by the kernel to CLOCK_MONOTONIC for simplicity.
If a caller would set FUTEX_CLOCK_REALTIME for FUTEX_WAIT the timeout is still treated relative vs. CLOCK_MONOTONIC and then the wait arms that timeout based on CLOCK_REALTIME which is broken and obviously has never been used or even tested.
Reject any attempt to use FUTEX_CLOCK_REALTIME with FUTEX_WAIT again.
The desired functionality can be achieved with FUTEX_WAIT_BITSET and a FUTEX_BITSET_MATCH_ANY argument.

LLVM's integrated assembler appears to assume an argument with default value is passed whenever it sees a comma right after the macro name. It will be fine if the number of following arguments is one less than the number of parameters specified in the macro definition. Otherwise, it fails. For example, the following code works:
$ cat foo.s .macro foo arg1=2, arg2=4 ldr r0, [r1, #\arg1] ldr r0, [r1, #\arg2] .endm
foo, arg2=8
$ llvm-mc -triple=armv7a -filetype=obj foo.s -o ias.o arm-linux-gnueabihf-objdump -dr ias.o
ias.o: file format elf32-littlearm
Disassembly of section .text:
00000000 <.text>: 0: e5910001 ldr r0, [r1, #2] 4: e5910003 ldr r0, [r1, #8]
While the the following code would fail:
$ cat foo.s .macro foo arg1=2, arg2=4 ldr r0, [r1, #\arg1] ldr r0, [r1, #\arg2] .endm
foo, arg1=2, arg2=8
$ llvm-mc -triple=armv7a -filetype=obj foo.s -o ias.o foo.s:6:14: error: too many positional arguments foo, arg1=2, arg2=8
This causes build failures as follows:
arch/arm64/kernel/vdso/gettimeofday.S:230:24: error: too many positional arguments clock_gettime_return, shift=1 ^ arch/arm64/kernel/vdso/gettimeofday.S:253:24: error: too many positional arguments clock_gettime_return, shift=1 ^ arch/arm64/kernel/vdso/gettimeofday.S:274:24: error: too many positional arguments clock_gettime_return, shift=1
This error is not in mainline because commit 28b1a824a4f4 ("arm64: vdso: Substitute gettimeofday() with C implementation") rewrote this assembler file in C as part of a 25 patch series that is unsuitable for stable. Just remove the comma in the clock_gettime_return invocations in 4.19 so that GNU as and LLVM's integrated assembler work the same.

Commit <50122847007> ("ext4: fix check to prevent initializing reserved inodes") check the block group zero and prevent initializing reserved inodes. But in some special cases, the reserved inode may not all belong to the group zero, it may exist into the second group if we format filesystem below.
mkfs.ext4 -b 4096 -g 8192 -N 1024 -I 4096 /dev/sda
So, it will end up triggering a false positive report of a corrupted file system. This patch fix it by avoid check reserved inodes if no free inode blocks will be zeroed.

commit 72ffb49a7b623c92a37657eda7cc46a06d3e8398 upstream.
When CONFIG_QUOTA is enabled, if we failed to mount the filesystem due to some error happens behind ext4_orphan_cleanup(), it will end up triggering a after free issue of super_block. The problem is that ext4_orphan_cleanup() will set SB_ACTIVE flag if CONFIG_QUOTA is enabled, after we cleanup the truncated inodes, the last iput() will put them into the lru list, and these inodes' pages may probably dirty and will be write back by the writeback thread, so it could be raced by freeing super_block in the error path of mount_bdev().
After check the setting of SB_ACTIVE flag in ext4_orphan_cleanup(), it was used to ensure updating the quota file properly, but evict inode and trash data immediately in the last iput does not affect the quotafile, so setting the SB_ACTIVE flag seems not required[1]. Fix this issue by just remove the SB_ACTIVE setting.

commit 4a5d797a9f9c4f18585544237216d7812686a71f upstream.
Fix a general protection fault reported by syzbot due to a race between gadget_setup() and gadget_unbind() in raw_gadget.
The gadget core is supposed to guarantee that there won't be any more callbacks to the gadget driver once the driver's unbind routine is called. That guarantee is enforced in usb_gadget_remove_driver as follows:
usb_gadget_disconnect(udc->gadget); if (udc->gadget->irq) synchronize_irq(udc->gadget->irq); udc->driver->unbind(udc->gadget); usb_gadget_udc_stop(udc);
usb_gadget_disconnect turns off the pullup resistor, telling the host that the gadget is no longer connected and preventing the transmission of any more USB packets. Any packets that have already been received are sure to processed by the UDC driver's interrupt handler by the time synchronize_irq returns.
But this doesn't work with dummy_hcd, because dummy_hcd doesn't use interrupts; it uses a timer instead. It does have code to emulate the effect of synchronize_irq, but that code doesn't get invoked at the right time -- it currently runs in usb_gadget_udc_stop, after the unbind callback instead of before. Indeed, there's no way for usb_gadget_remove_driver to invoke this code before the unbind callback.
To fix this, move the synchronize_irq() emulation code to dummy_pullup so that it runs before unbind. Also, add a comment explaining why it is necessary to have it there.

Upon driver unbind usb_free_all_descriptors() function frees all speed descriptor pointers without setting them to NULL. In case gadget speed changes (i.e from super speed plus to super speed) after driver unbind only upto super speed descriptor pointers get populated. Super speed plus desc still holds the stale (already freed) pointer. Fix this issue by setting all descriptor pointers to NULL after freeing them in usb_free_all_descriptors().

commit c560e76319a94a3b9285bc426c609903408e4826 upstream.
The START_TRANSFER command needs to be executed while in ON/U0 link state (with an exception during register initialization). Don't use dwc->link_state to check this since the driver only tracks the link state when the link state change interrupt is enabled. Check the link state from DSTS register instead.
Note that often the host already brings the device out of low power before it sends/requests the next transfer. So, the user won't see any issue when the device starts transfer then. This issue is more noticeable in cases when the device delays starting transfer, which can happen during delayed control status after the host put the device in low power.

commit 785e3c0a3a870e72dc530856136ab4c8dd207128 upstream.
The default max PID is set by PID_MAX_DEFAULT, and the tracing infrastructure uses this number to map PIDs to the comm names of the tasks, such output of the trace can show names from the recorded PIDs in the ring buffer. This mapping is also exported to user space via the "saved_cmdlines" file in the tracefs directory.
But currently the mapping expects the PIDs to be less than PID_MAX_DEFAULT, which is the default maximum and not the real maximum. Recently, systemd will increases the maximum value of a PID on the system, and when tasks are traced that have a PID higher than PID_MAX_DEFAULT, its comm is not recorded. This leads to the entire trace to have "<...>" as the comm name, which is pretty useless.
Instead, keep the array mapping the size of PID_MAX_DEFAULT, but instead of just mapping the index to the comm, map a mask of the PID (PID_MAX_DEFAULT - 1) to the comm, and find the full PID from the map_cmdline_to_pid array (that already exists).
This bug goes back to the beginning of ftrace, but hasn't been an issue until user space started increasing the maximum value of PIDs.

commit aafe104aa9096827a429bc1358f8260ee565b7cc upstream.
It was reported that a fix to the ring buffer recursion detection would cause a hung machine when performing suspend / resume testing. The following backtrace was extracted from debugging that case:
Call Trace: trace_clock_global+0x91/0xa0 __rb_reserve_next+0x237/0x460 ring_buffer_lock_reserve+0x12a/0x3f0 trace_buffer_lock_reserve+0x10/0x50 __trace_graph_return+0x1f/0x80 trace_graph_return+0xb7/0xf0 ? trace_clock_global+0x91/0xa0 ftrace_return_to_handler+0x8b/0xf0 ? pv_hash+0xa0/0xa0 return_to_handler+0x15/0x30 ? ftrace_graph_caller+0xa0/0xa0 ? trace_clock_global+0x91/0xa0 ? __rb_reserve_next+0x237/0x460 ? ring_buffer_lock_reserve+0x12a/0x3f0 ? trace_event_buffer_lock_reserve+0x3c/0x120 ? trace_event_buffer_reserve+0x6b/0xc0 ? trace_event_raw_event_device_pm_callback_start+0x125/0x2d0 ? dpm_run_callback+0x3b/0xc0 ? pm_ops_is_empty+0x50/0x50 ? platform_get_irq_byname_optional+0x90/0x90 ? trace_device_pm_callback_start+0x82/0xd0 ? dpm_run_callback+0x49/0xc0
With the following RIP:
RIP: 0010:native_queued_spin_lock_slowpath+0x69/0x200
Since the fix to the recursion detection would allow a single recursion to happen while tracing, this lead to the trace_clock_global() taking a spin lock and then trying to take it again:
ring_buffer_lock_reserve() { trace_clock_global() { arch_spin_lock() { queued_spin_lock_slowpath() { /* lock taken */ (something else gets traced by function graph tracer) ring_buffer_lock_reserve() { trace_clock_global() { arch_spin_lock() { queued_spin_lock_slowpath() { /* DEAD LOCK! */
Tracing should *never* block, as it can lead to strange lockups like the above.
Restructure the trace_clock_global() code to instead of simply taking a lock to update the recorded "prev_time" simply use it, as two events happening on two different CPUs that calls this at the same time, really doesn't matter which one goes first. Use a trylock to grab the lock for updating the prev_time, and if it fails, simply try again the next time. If it failed to be taken, that means something else is already updating it.

When allocation/initialization of the blk_mq_tag_set fails in dm_mq_init_request_queue(), it is uninitialized/freed, but the pointer is not reset to NULL; so when dev_remove() later gets into dm_mq_cleanup_mapped_device() it sees the pointer and tries to uninitialize and free it again.
Fix this by setting the pointer to NULL in dm_mq_init_request_queue() error-handling. Also set it to NULL in dm_mq_cleanup_mapped_device().

If a TAINT_PROPRIETARY_MODULE exports symbol, inherit the taint flag for all modules importing these symbols, and don't allow loading symbols from TAINT_PROPRIETARY_MODULE modules if the module previously imported gplonly symbols. Add a anti-circumvention devices so people don't accidentally get themselves into trouble this way.

commit 5c4c8c9544099bb9043a10a5318130a943e32fc3 upstream.
hci_chan can be created in 2 places: hci_loglink_complete_evt() if it is an AMP hci_chan, or l2cap_conn_add() otherwise. In theory, Only AMP hci_chan should be removed by a call to hci_disconn_loglink_complete_evt(). However, the controller might mess up, call that function, and destroy an hci_chan which is not initiated by hci_loglink_complete_evt().
This patch adds a verification that the destroyed hci_chan must have been init'd by hci_loglink_complete_evt().

commit 4b793acdca0050739b99ace6a8b9e7f717f57c6b upstream.
When HSR interface is sending a frame, it finds a node with the destination ethernet address from the list. If there is no node, it calls WARN_ONCE(). But, using WARN_ONCE() for this situation is a little bit overdoing. So, in this patch, the netdev_err() is used instead.

commit c61760e6940dd4039a7f5e84a6afc9cdbf4d82b6 upstream.
Commits 8a4cd82d ("nfc: fix refcount leak in llcp_sock_connect()") and c33b1cc62 ("nfc: fix refcount leak in llcp_sock_bind()") fixed a refcount leak bug in bind/connect but introduced a use-after-free if the same local is assigned to 2 different sockets.
This can be triggered by the following simple program: int sock1 = socket( AF_NFC, SOCK_STREAM, NFC_SOCKPROTO_LLCP ); int sock2 = socket( AF_NFC, SOCK_STREAM, NFC_SOCKPROTO_LLCP ); memset( &addr, 0, sizeof(struct sockaddr_nfc_llcp) ); addr.sa_family = AF_NFC; addr.nfc_protocol = NFC_PROTO_NFC_DEP; bind( sock1, (struct sockaddr*) &addr, sizeof(struct sockaddr_nfc_llcp) ) bind( sock2, (struct sockaddr*) &addr, sizeof(struct sockaddr_nfc_llcp) ) close(sock1); close(sock2);
Fix this by assigning NULL to llcp_sock->local after calling nfc_llcp_local_put.
This addresses CVE-2021-23134.

commit c15b99ae2ba9ea30da3c7cd4765b8a4707e530a6 upstream.
Upstream a long-standing OpenWrt patch [0] that fixes MT7620 PCIe PLL lock check. The existing code checks the wrong register bit: PPLL_SW_SET is not defined in PPLL_CFG1 and bit 31 of PPLL_CFG1 is marked as reserved in the MT7620 Programming Guide. The correct bit to check for PLL lock is PPLL_LD (bit 23).
Also reword the error message for clarity.
Without this change it is unlikely that this driver ever worked with mainline kernel.

commit 8e98b697006d749d745d3b174168a877bb96c500 upstream.
pci_fixup_irqs() used to call pcibios_map_irq on every PCI device, which for RT2880 included bus 0 slot 0. After pci_fixup_irqs() got removed, only slots/funcs with devices attached would be called. While arguably the right thing, that left no chance for this driver to ever initialize slot 0, effectively bricking PCI and USB on RT2880 devices such as the Belkin F5D8235-4 v1.
Slot 0 configuration needs to happen after PCI bus enumeration, but before any device at slot 0x11 (func 0 or 1) is talked to. That was determined empirically by testing on a Belkin F5D8235-4 v1 device. A minimal BAR 0 config write followed by read, then setting slot 0 PCI_COMMAND to MASTER | IO | MEMORY is all that seems to be required for proper functionality.
Tested by ensuring that full- and high-speed USB devices get enumerated on the Belkin F5D8235-4 v1 (with an out of tree DTS file from OpenWrt).

commit f626ca682912fab55dff15469ce893ae16b65c7e upstream.
Recent versions of the PCI Express specification have deprecated support for I/O transactions and actually some PCIe host bridges, such as Power Systems Host Bridge 4 (PHB4), do not implement them.
For those systems the PCI BARs that request a mapping in the I/O space have the length recorded in the corresponding PCI resource set to zero, which makes it unassigned:
# lspci -s 0031:02:04.0 -v 0031:02:04.0 FDDI network controller: Digital Equipment Corporation PCI-to-PDQ Interface Chip [PFI] FDDI (DEFPA) (rev 02) Subsystem: Digital Equipment Corporation FDDIcontroller/PCI (DEFPA) Flags: bus master, medium devsel, latency 136, IRQ 57, NUMA node 8 Memory at 620c080020000 (32-bit, non-prefetchable) [size=128] I/O ports at <unassigned> [disabled] Memory at 620c080030000 (32-bit, non-prefetchable) [size=64K] Capabilities: [50] Power Management version 2 Kernel driver in use: defxx Kernel modules: defxx
#
Regardless the driver goes ahead and requests it (here observed with a Raptor Talos II POWER9 system), resulting in an odd /proc/ioport entry:
# cat /proc/ioports 00000000-ffffffffffffffff : 0031:02:04.0 #
Furthermore, the system gets confused as the driver actually continues and pokes at those locations, causing a flood of messages being output to the system console by the underlying system firmware, like:
defxx: v1.11 2014/07/01 Lawrence V. Stefani and others defxx 0031:02:04.0: enabling device (0140 -> 0142) LPC[000]: Got SYNC no-response error. Error address reg: 0xd0010000 IPMI: dropping non severe PEL event LPC[000]: Got SYNC no-response error. Error address reg: 0xd0010014 IPMI: dropping non severe PEL event LPC[000]: Got SYNC no-response error. Error address reg: 0xd0010014 IPMI: dropping non severe PEL event
and so on and so on (possibly intermixed actually, as there's no locking between the kernel and the firmware in console port access with this particular system, but cleaned up above for clarity), and once some 10k of such pairs of the latter two messages have been produced an interace eventually shows up in a useless state:
0031:02:04.0: DEFPA at I/O addr = 0x0, IRQ = 57, Hardware addr = 00-00-00-00-00-00
This was not expected to happen as resource handling was added to the driver a while ago, because it was not known at that time that a PCI system would be possible that cannot assign port I/O resources, and oddly enough `request_region' does not fail, which would have caught it.
Correct the problem then by checking for the length of zero for the CSR resource and bail out gracefully refusing to register an interface if that turns out to be the case, producing messages like:
defxx: v1.11 2014/07/01 Lawrence V. Stefani and others 0031:02:04.0: Cannot use I/O, no address set, aborting 0031:02:04.0: Recompile driver with "CONFIG_DEFXX_MMIO=y"
Keep the original check for the EISA MMIO resource as implemented, because in that case the length is hardwired to 0x400 as a consequence of how the compare/mask address decoding works in the ESIC chip and it is only the base address that is set to zero if MMIO has been disabled for the adapter in EISA configuration, which in turn could be a valid bus address in a legacy-free system implementing PCI, especially for port I/O.
Where the EISA MMIO resource has been disabled for the adapter in EISA configuration this arrangement keeps producing messages like:
eisa 00:05: EISA: slot 5: DEC3002 detected defxx: v1.11 2014/07/01 Lawrence V. Stefani and others 00:05: Cannot use MMIO, no address set, aborting 00:05: Recompile driver with "CONFIG_DEFXX_MMIO=n" 00:05: Or run ECU and set adapter's MMIO location
with the last two lines now swapped for easier handling in the driver.
There is no need to check for and catch the case of a port I/O resource not having been assigned for EISA as the adapter uses the slot-specific I/O space, which gets assigned by how EISA has been specified and maps directly to the particular slot an option card has been placed in. And the EISA variant of the adapter has additional registers that are only accessible via the port I/O space anyway.
While at it factor out the error message calls into helpers and fix an argument order bug with the `pr_err' call now in `dfx_register_res_err'.

commit 4e102429f3dc62dce546f6107e34a4284634196d upstream.
Whilst running some basic tests as part of writing up the dt-bindings for this driver (to follow), it became clear it doesn't actually load currently.
iio iio:device1: tried to double register : in_incli_x_index adis16201 spi0.0: Failed to create buffer sysfs interfaces adis16201: probe of spi0.0 failed with error -16
Looks like a cut and paste / update bug. Fixes tag obviously not accurate but we don't want to bother carry thing back to before the driver moved out of staging.

commit 3641762c1c9c7cfd84a7061a0a73054f09b412e3 upstream.
Before this commit lis3lv02d_get_pwron_wait() had a WARN_ONCE() to catch a potential divide by 0. WARN macros should only be used to catch internal kernel bugs and that is not the case here. We have been receiving a lot of bug reports about kernel backtraces caused by this WARN.
The div value being checked comes from the lis3->odrs[] array. Which is sized to be a power-of-2 matching the number of bits in lis3->odr_mask.
The only lis3 model where this array is not entirely filled with non zero values. IOW the only model where we can hit the div == 0 check is the 3dc ("8 bits 3DC sensor") model:
int lis3_3dc_rates[16] = {0, 1, 10, 25, 50, 100, 200, 400, 1600, 5000};
Note the 0 value at index 0, according to the datasheet an odr index of 0 means "Power-down mode". HP typically uses a lis3 accelerometer for HDD fall protection. What I believe is happening here is that on newer HP devices, which only contain a SDD, the BIOS is leaving the lis3 device powered-down since it is not used for HDD fall protection.
Note that the lis3_3dc_rates array initializer only specifies 10 values, which matches the datasheet. So it also contains 6 zero values at the end.
Replace the WARN with a normal check, which treats an odr index of 0 as power-down and uses a normal dev_err() to report the error in case odr index point past the initialized part of the array.

bio in the above stack is a bitmap write whose completion is invoked after the tear down sequence sets the mddev structure to NULL in rdev.
During tear down, there is an attempt to flush the bitmap writes, but for external bitmaps, there is no explicit wait for all the bitmap writes to complete. For instance, md_bitmap_flush() is called to flush the bitmap writes, but the last call to md_bitmap_daemon_work() in md_bitmap_flush() could generate new bitmap writes for which there is no explicit wait to complete those writes. The call to md_bitmap_update_sb() will return simply for external bitmaps and the follow-up call to md_update_sb() is conditional and may not get called for external bitmaps. This results in a kernel panic when the completion routine, super_written() is called which tries to reference mddev in the rdev that has been set to NULL(in unbind_rdev_from_array() by tear down sequence).
The solution is to call md_super_wait() for external bitmaps after the last call to md_bitmap_daemon_work() in md_bitmap_flush() to ensure there are no pending bitmap writes before proceeding with the tear down.

commit 65aa97c4d2bfd76677c211b9d03ef05a98c6d68e upstream.
Split mddev_find into a simple mddev_find that just finds an existing mddev by the unit number, and a more complicated mddev_find that deals with find or allocating a mddev.
This turns out to fix this bug reported by Zhao Heming.

The md_open shouldn't create mddev when all_mddevs list doesn't contain mddev. With currently code logic, there will be very easy to trigger soft lockup in non-preempt env.
This patch changes md_open returning from -ERESTARTSYS to -EBUSY, which will break the infinitely retry when md_open enter racing area.
This patch is partly fix soft lockup issue, full fix needs mddev_find is split into two functions: mddev_find & mddev_find_or_alloc. And md_open should call new mddev_find (it only does searching job).
For more detail, please refer with Christoph's "split mddev_find" patch in later commits.

commit 7abfabaf5f805f5171d133ce6af9b65ab766e76a upstream.
Reading /proc/mdstat with a read buffer size that would not fit the unused status line in the first read will skip this line from the output.
So 'dd if=/proc/mdstat bs=64 2>/dev/null' will not print something like: unused devices: <none>
Don't return NULL immediately in start() for v=2 but call show() once to print the status line also for multiple reads.

Just re-order the alc269_fixup_tbl[] entries for HP devices for avoiding the oversight of the duplicated or unapplied item in future. No functional changes.
Formerly, some entries were grouped for the actual codec, but this doesn't seem reasonable to keep in that way. So now we simply keep the PCI SSID order for the whole.

The quirk entry for Uniwill ECS M31EI is with the PCI SSID device 0, which means matching with all. That is, it's essentially equivalent with SND_PCI_QUIRK_VENDOR(0x1584), which also matches with the previous entry for Haier W18 applying the very same quirk.
Let's unify them with the single vendor-quirk entry.

commit b6b4fbd90b155a0025223df2c137af8a701d53b3 upstream.
Initialize MSR_TSC_AUX with CPU node information if RDTSCP or RDPID is supported. This fixes a bug where vdso_read_cpunode() will read garbage via RDPID if RDPID is supported but RDTSCP is not. While no known CPU supports RDPID but not RDTSCP, both Intel's SDM and AMD's APM allow for RDPID to exist without RDTSCP, e.g. it's technically a legal CPU model for a virtual machine.
Note, technically MSR_TSC_AUX could be initialized if and only if RDPID is supported since RDTSCP is currently not used to retrieve the CPU node. But, the cost of the superfluous WRMSR is negigible, whereas leaving MSR_TSC_AUX uninitialized is just asking for future breakage if someone decides to utilize RDTSCP.

commit f85f1baaa18932a041fd2b1c2ca6cfd9898c7d2b upstream.
Split kvm_s390_logical_to_effective to a generic function called _kvm_s390_logical_to_effective. The new function takes a PSW and an address and returns the address with the appropriate bits masked off. The old function now calls the new function with the appropriate PSW from the vCPU.
This is needed to avoid code duplication for vSIE.

commit 44bada28219031f9e8e86b84460606efa57b871e upstream.
store_regs_fmt2() has an ordering problem: first the guarded storage facility is enabled on the local cpu, then preemption disabled, and then the STGSC (store guarded storage controls) instruction is executed.
If the process gets scheduled away between enabling the guarded storage facility and before preemption is disabled, this might lead to a special operation exception and therefore kernel crash as soon as the process is scheduled back and the STGSC instruction is executed.

Currently the array gpmc_cs is indexed by cs before it cs is range checked and the pointer read from this out-of-index read is dereferenced. Fix this by performing the range check on cs before the read and the following pointer dereference.

In "tx_empty", we should poll TC bit in both DMA and PIO modes (instead of TXE) to check transmission data register has been transmitted independently of the FIFO mode. TC indicates that both transmit register and shift register are empty. When shift register is empty, tx_empty should return TIOCSER_TEMT instead of TC value.
Cleans the USART_CR_TC TCCF register define (transmission complete clear flag) as it is duplicate of USART_ICR_TCCF.

While interpreting CC_STATUS, ROLE_CONTROL has to be read to make sure that CC1/CC2 is not forced presenting Rp/Rd.
From the TCPCI spec:
4.4.5.2 ROLE_CONTROL (Normative): The TCPM shall write B6 (DRP) = 0b and B3..0 (CC1/CC2) if it wishes to control the Rp/Rd directly instead of having the TCPC perform DRP toggling autonomously. When controlling Rp/Rd directly, the TCPM writes to B3..0 (CC1/CC2) each time it wishes to change the CC1/CC2 values. This control is used for TCPM-TCPC implementing Source or Sink only as well as when a connection has been detected via DRP toggling but the TCPM wishes to attempt Try.Src or Try.Snk.

Hamming ECC doesn't cover the OOB data, so reading or writing OOB shall always be done without ECC enabled. This is a problem when adding JFFS2 cleanmarkers to erased blocks. If JFFS2 clenmarkers are added to the OOB with ECC enabled, OOB bytes will be changed from ff ff ff to 00 00 00, reporting incorrect ECC errors.

[ Upstream commit 08608adb520e51403be7592c2214846fa440a23a ]
There are chances that the parse_mtd_partitions() function will return -EPROBE_DEFER in mtd_device_parse_register(). This might happen when the dependency is not available for the parser. For instance, on SDX55 the MTD_QCOMSMEM_PARTS parser depends on the QCOM_SMEM driver to parse the partitions defined in the shared memory region. With the current flow, the error returned from parse_mtd_partitions() will be discarded in favor of trying to add the fallback partition.
This will prevent the driver to end up in probe deferred pool and the partitions won't be parsed even after the QCOM_SMEM driver is available.
Fix this issue by bailing out of mtd_device_parse_register() when -EPROBE_DEFER error is returned from parse_mtd_partitions() function and propagate the error code to the driver core for probing later.

In qcom_probe_nand_devices() function, the error code returned by qcom_nand_host_init_and_register() is converted to -ENODEV in the case of failure. This poses issue if -EPROBE_DEFER is returned when the dependency is not available for a component like parser.

[ Upstream commit 7189b3c11903667808029ec9766a6e96de5012a5 ]
Currently, the late microcode loading mechanism checks whether any CPUs are offlined, and, in such a case, aborts the load attempt.
However, this must be done before the kernel caches new microcode from the filesystem. Otherwise, when offlined CPUs are onlined later, those cores are going to be updated through the CPU hotplug notifier callback with the new microcode, while CPUs previously onine will continue to run with the older microcode.
For example:
Turn off one core (2 threads):
echo 0 > /sys/devices/system/cpu/cpu3/online echo 0 > /sys/devices/system/cpu/cpu1/online
Install the ucode fails because a primary SMT thread is offline:
cp intel-ucode/06-8e-09 /lib/firmware/intel-ucode/ echo 1 > /sys/devices/system/cpu/microcode/reload bash: echo: write error: Invalid argument
Turn the core back on
echo 1 > /sys/devices/system/cpu/cpu3/online echo 1 > /sys/devices/system/cpu/cpu1/online cat /proc/cpuinfo |grep microcode microcode : 0x30 microcode : 0xde microcode : 0x30 microcode : 0xde
The rationale for why the update is aborted when at least one primary thread is offline is because even if that thread is soft-offlined and idle, it will still have to participate in broadcasted MCE's synchronization dance or enter SMM, and in both examples it will execute instructions so it better have the same microcode revision as the other cores.

When the EP0 IN request was not completed but less than a packet sent, it would complete the request successfully. That doesn't make sense and can't really happen as fotg210_start_dma always sends min(length, maxpkt) bytes.

Currently it leaves unhandled interrupts unmasked, but those are never acked. In the case of a "device idle" interrupt, this leads to an effectively frozen system until plugging it in.

Currently the virtual port_dev device is passed to DMA API, and this is wrong because the device passed to DMA API calls must be the actual hardware device performing the DMA.
The patch replaces usb_gadget_map_request/usb_gadget_unmap_request APIs with usb_gadget_map_request_by_dev/usb_gadget_unmap_request_by_dev APIs so the DMA capable platform device can be passed to the DMA APIs.

[ Upstream commit 076de75de1e53160e9b099f75872c1f9adf41a0b ]
If the callee gpmi_alloc_dma_buffer() failed to alloc memory for this->raw_buffer, gpmi_free_dma_buffer() will be called to free this->auxiliary_virt. But this->auxiliary_virt is still a non-NULL and valid ptr.
Then gpmi_alloc_dma_buffer() returns err and gpmi_free_dma_buffer() is called again to free this->auxiliary_virt in err_out. This causes a double free.
As gpmi_free_dma_buffer() has already called in gpmi_alloc_dma_buffer's error path, so it should return err directly instead of releasing the dma buffer again.

Fix the greybus implementation which instead indicated that the TIOCSSERIAL ioctl was not even implemented when a non-privileged user set the current values.

All of the CPPC sysfs show functions are called via indirect call in kobj_attr_show(), where they should be of type
ssize_t (*show)(struct kobject *kobj, struct kobj_attribute *attr, char *buf);
because that is the type of the ->show() member in 'struct kobj_attribute' but they are actually of type
ssize_t (*show)(struct kobject *kobj, struct attribute *attr, char *buf);
because of the ->show() member in 'struct cppc_attr', resulting in a Control Flow Integrity violation [1].

$ dmesg | grep "CFI failure" [ 175.970559] CFI failure (target: show_highest_perf+0x0/0x8):
As far as I can tell, the only difference between 'struct cppc_attr' and 'struct kobj_attribute' aside from the type of the attr parameter is the type of the count parameter in the ->store() member (ssize_t vs. size_t), which does not actually matter because all of these nodes are read-only.
Eliminate 'struct cppc_attr' in favor of 'struct kobj_attribute' to fix the violation.

[ Upstream commit 22592df194e31baf371906cc720da38fa0ab68f5 ]
With CPU frequency determining software [1] we have discovered that after this driver does one CPU frequency change, the base frequency of the CPU is set to the frequency of TBG-A-P clock, instead of the TBG that is parent to the CPU.
This can be reproduced on EspressoBIN and Turris MOX: cd /sys/devices/system/cpu/cpufreq/policy0 echo powersave >scaling_governor echo performance >scaling_governor
Running the mhz tool before this driver is loaded reports 1000 MHz, and after loading the driver and executing commands above the tool reports 800 MHz.
The change of TBG clock selector is supposed to happen in function armada37xx_cpufreq_dvfs_setup. Before the function returns, it does this: parent = clk_get_parent(clk); clk_set_parent(clk, parent);
The armada-37xx-periph clock driver has the .set_parent method implemented correctly for this, so if the method was actually called, this would work. But since the introduction of the common clock framework in commit b2476490ef11 ("clk: introduce the common clock..."), the clk_set_parent function checks whether the parent is actually changing, and if the requested new parent is same as the old parent (which is obviously the case for the code above), the .set_parent method is not called at all.
This patch fixes this issue by filling the correct TBG clock selector directly in the armada37xx_cpufreq_dvfs_setup during the filling of other registers at the same address. But the determination of CPU TBG index cannot be done via the common clock framework, therefore we need to access the North Bridge Peripheral Clock registers directly in this driver.

Remove the .set_parent method in clk_pm_cpu_ops.
This method was supposed to be needed by the armada-37xx-cpufreq driver, but was never actually called due to wrong assumptions in the cpufreq driver. After this was fixed in the cpufreq driver, this method is not needed anymore.

The original CPU voltage value for load L1 is too low for Armada 37xx SoC when base CPU frequency is 1000 or 1200 MHz. It leads to instabilities where CPU gets stuck soon after dynamic voltage scaling from load L1 to L0.
Update the CPU voltage value for load L1 accordingly when base frequency is 1000 or 1200 MHz. The minimal L1 value for base CPU frequency 1000 MHz is updated from the original 1.05V to 1.108V and for 1200 MHz is updated to 1.155V. This minimal L1 value is used only in the case when it is lower than value for L0.
This change fixes CPU instability issues on 1 GHz and 1.2 GHz variants of Espressobin and 1 GHz Turris Mox.
Marvell previously for 1 GHz variant of Espressobin provided a patch [1] suitable only for their Marvell Linux kernel 4.4 fork which workarounded this issue. Patch forced CPU voltage value to 1.108V in all loads. But such change does not fix CPU instability issues on 1.2 GHz variants of Armada 3720 SoC.
During testing we come to the conclusion that using 1.108V as minimal value for L1 load makes 1 GHz variants of Espressobin and Turris Mox boards stable. And similarly 1.155V for 1.2 GHz variant of Espressobin.
These two values 1.108V and 1.155V are documented in Armada 3700 Hardware Specifications as typical initial CPU voltage values.
Discussion about this issue is also at the Armbian forum [2].

It was observed that the workaround introduced by commit 61c40f35f5cd ("clk: mvebu: armada-37xx-periph: Fix switching CPU rate from 300Mhz to 1.2GHz") when base CPU frequency is 1.2 GHz is also required when base CPU frequency is 1 GHz. Otherwise switching CPU frequency directly from L2 (250 MHz) to L0 (1 GHz) causes a crash.
When base CPU frequency is just 800 MHz no crashed were observed during switch from L2 to L0.

When CPU frequency is at 250 MHz and set_rate() is called with 500 MHz (L1) quickly followed by a call with 1 GHz (L0), the CPU does not necessarily stay in L1 for at least 20ms as is required by Marvell errata.
This situation happens frequently with the ondemand cpufreq governor and can be also reproduced with userspace governor. In most cases it causes CPU to crash.
This change fixes the above issue and ensures that the CPU always stays in L1 for at least 20ms when switching from any state to L0.

Fix the misspelled "__KERNEL__" compile guards which failed their sole purpose to break out-of-tree drivers that have not yet been updated.

Drivers should return -ENOTTY ("Inappropriate I/O control operation") when an ioctl isn't supported, while -EINVAL is used for invalid arguments.
Fix up the TIOCMGET, TIOCMSET and TIOCGICOUNT helpers which returned -EINVAL when a tty driver did not implement the corresponding operations.
Note that the TIOCMGET and TIOCMSET helpers predate git and do not get a corresponding Fixes tag below.

pmc_plt_clk* clocks are used for ethernet controllers, so need to stay turned on. This adds the affected board family to critclk_systems DMI table, so the clocks are marked as CLK_CRITICAL and not turned off.
This replaces the previously listed boards with a match for the whole device family CBxx63. CBxx63 matches only baytrail devices. There are new affected boards that would otherwise need to be listed. There are unaffected boards in the family, but having the clocks turned on is not an issue.

When KEXEC is disabled, the UV build fails:
arch/x86/platform/uv/uv_nmi.c:875:14: error: ‘uv_nmi_kexec_failed’ undeclared (first use in this function)
Since uv_nmi_kexec_failed is only defined in the KEXEC_CORE #ifdef branch, this code cannot ever have been build tested:
if (main) pr_err("UV: NMI kdump: KEXEC not supported in this kernel\n"); atomic_set(&uv_nmi_kexec_failed, 1);
Nor is this use possible in uv_handle_nmi():
atomic_set(&uv_nmi_kexec_failed, 0);
These bugs were introduced in this commit:
d0a9964e9873: ("x86/platform/uv: Implement simple dump failover if kdump fails")
Which added the uv_nmi_kexec_failed assignments to !KEXEC code, while making the definition KEXEC-only - apparently without testing the !KEXEC case.
Instead of complicating the #ifdef maze, simplify the code by requiring X86_UV to depend on KEXEC_CORE. This pattern is present in other architectures as well.
( We'll remove the untested, 7 years old !KEXEC complications from the file in a separate commit. )

[ Upstream commit 77db0ec8b7764cb9b09b78066ebfd47b2c0c1909 ]
When running in Azure, disks may be connected to a Linux VM with read/write caching enabled. If a VM panics and issues a VMbus UNLOAD request to Hyper-V, the response is delayed until all dirty data in the disk cache is flushed. In extreme cases, this flushing can take 10's of seconds, depending on the disk speed and the amount of dirty data. If kdump is configured for the VM, the current 10 second timeout in vmbus_wait_for_unload() may be exceeded, and the UNLOAD complete message may arrive well after the kdump kernel is already running, causing problems. Note that no problem occurs if kdump is not enabled because Hyper-V waits for the cache flush before doing a reboot through the BIOS/UEFI code.
Fix this problem by increasing the timeout in vmbus_wait_for_unload() to 100 seconds. Also output periodic messages so that if anyone is watching the serial console, they won't think the VM is completely hung.

When core is in hibernation in host mode and a device cable was connected then driver exited from device hibernation. However, registers saved for host mode and when exited from device hibernation register restore would be done for device register which was wrong because there was no device registers stored to restore.
- Added dwc_handle_gpwrdn_disc_det() function which handles gpwrdn disconnect detect flow and exits hibernation without restoring the registers. - Updated exiting from hibernation in GPWRDN_STS_CHGINT with calling dwc_handle_gpwrdn_disc_det() function. Here no register is restored which is the solution described above.

syzbot is reporting hung task due to flood of

message [1], for ioctl(TIOCVHANGUP) prevents tty_port_close() from decrementing port->count due to tty_hung_up_p() == true.

The intent here was to return negative error codes but it actually returns positive values. The problem is that type promotion with ternary operations is quite complicated.
"ret" is an int. "copied" is a u32. And the snoop_file_read() function returns long. What happens is that "ret" is cast to u32 and becomes positive then it's cast to long and it's still positive.
Fix this by removing the ternary so that "ret" is type promoted directly to long.

There are 2 bugs in the can_boost() function because of using x86 insn decoder. Since the insn->opcode never has a prefix byte, it can not find CS override prefix in it. And the insn->attr is the attribute of the opcode, thus inat_is_address_size_prefix( insn->attr) always returns false.
Fix those by checking each prefix bytes with for_each_insn_prefix loop and getting the correct attribute for each prefix byte. Also, this removes unlikely, because this is a slow path.

Rewrite the driver's IRQ checking code to pass the positive IRQ #s to ata_host_activate(), propagate upstream -EPROBE_DEFER, and set up the driver to polling mode on (negative) errors and IRQ0 (libata treats IRQ #0 as a polling mode anyway)...

There is a small race where the parent is NULL even though the kobj has already been made visible in sysfs.
For instance the attribute_group is made visible in sysfs_create_files() and the mdev_type_attr_show() does:
ret = attr->show(kobj, type->parent->dev, buf);
Which will crash on NULL parent. Move the parent setup to before the type pointer leaves the stack frame.

The for-loop iterates with a u8 loop counter i and compares this with the loop upper limit of num_parents that is an int type. There is a potential infinite loop if num_parents is larger than the u8 loop counter. Fix this by making the loop counter the same type as num_parents. Also make num_parents an unsigned int to match the return type of the call to clk_hw_get_num_parents.

This fixes an issue hitting the BUG_ON() in ibmvfc_do_work(). When going through a host action of IBMVFC_HOST_ACTION_RESET, we change the action to IBMVFC_HOST_ACTION_TGT_DEL, then drop the host lock, and reset the CRQ, which changes the host state to IBMVFC_NO_CRQ. If, prior to setting the host state to IBMVFC_NO_CRQ, ibmvfc_init_host() is called, it can then end up changing the host action to IBMVFC_HOST_ACTION_INIT. If we then change the host state to IBMVFC_NO_CRQ, we will then hit the BUG_ON().
Make a couple of changes to avoid this. Leave the host action to be IBMVFC_HOST_ACTION_RESET or IBMVFC_HOST_ACTION_REENABLE until after we drop the host lock and reset or reenable the CRQ. Also harden the host state machine to ensure we cannot leave the reset / reenable state until we've finished processing the reset or reenable.

The ARR register is cleared unconditionally upon probing, after the maximum value has been read. This initial condition is rather not intuitive, when considering the counter child driver. It rather expects the maximum value by default: - The counter interface shows a zero value by default for 'ceiling' attribute. - Enabling the counter without any prior configuration makes it doesn't count.
The reset value of ARR register is the maximum. So Choice here is to backup it, and restore it then, instead of clearing its value. It also fixes the initial condition seen by the counter driver.

[ Upstream commit ad789f84c9a145f8a18744c0387cec22ec51651e ]
The handling of sysrq key can be activated by echoing the key to /proc/sysrq-trigger or via the magic key sequence typed into a terminal that is connected to the system in some way (serial, USB or other mean). In the former case, the handling is done in a user context. In the latter case, it is likely to be in an interrupt context.
Currently in print_cpu() of kernel/sched/debug.c, sched_debug_lock is taken with interrupt disabled for the whole duration of the calls to print_*_stats() and print_rq() which could last for the quite some time if the information dump happens on the serial console.
If the system has many cpus and the sched_debug_lock is somehow busy (e.g. parallel sysrq-t), the system may hit a hard lockup panic depending on the actually serial console implementation of the system.
The purpose of sched_debug_lock is to serialize the use of the global cgroup_path[] buffer in print_cpu(). The rests of the printk calls don't need serialization from sched_debug_lock.
Calling printk() with interrupt disabled can still be problematic if multiple instances are running. Allocating a stack buffer of PATH_MAX bytes is not feasible because of the limited size of the kernel stack.
The solution implemented in this patch is to allow only one caller at a time to use the full size group_path[], while other simultaneous callers will have to use shorter stack buffers with the possibility of path name truncation. A "..." suffix will be printed if truncation may have happened. The cgroup path name is provided for informational purpose only, so occasional path name truncation should not be a big problem.

In null_init, null_add_dev(dev) is called. In null_add_dev, it calls null_free_zoned_dev(dev) to free dev->zones via kvfree(dev->zones) in out_cleanup_zone branch and returns err. Then null_init accept the err code and then calls null_free_dev(dev).
But in null_free_dev(dev), dev->zones is freed again by null_free_zoned_dev().
My patch set dev->zones to NULL in null_free_zoned_dev() after kvfree(dev->zones) is called, to avoid the double free.

Plantronics Blackwire 3220 Series (047f:c056) sends HID reports twice for each volume key press. This patch adds a quirk to hid-plantronics for this product ID, which will ignore the second volume key press if it happens within 5 ms from the last one that was handled.
The patch was tested on the mentioned model only, it shouldn't affect other models, however, this quirk might be needed for them too. Auto-repeat (when a key is held pressed) is not affected, because the rate is about 3 times per second, which is far less frequent than once in 5 ms.

There are two "netif_running" checks in this driver. One is in "lapbeth_xmit" and the other is in "lapbeth_rcv". They serve to make sure that the LAPB APIs called in these functions are called before "lapb_unregister" is called by the "ndo_stop" function.
However, these "netif_running" checks are unreliable, because it's possible that immediately after "netif_running" returns true, "ndo_stop" is called (which causes "lapb_unregister" to be called).
This patch adds locking to make sure "lapbeth_xmit" and "lapbeth_rcv" can reliably check and ensure the netif is running while doing their work.

If identical_pvr_fixup() is not inlined, there are two modpost warnings:
WARNING: modpost: vmlinux.o(.text+0x54e8): Section mismatch in reference from the function identical_pvr_fixup() to the function .init.text:of_get_flat_dt_prop() The function identical_pvr_fixup() references the function __init of_get_flat_dt_prop(). This is often because identical_pvr_fixup lacks a __init annotation or the annotation of of_get_flat_dt_prop is wrong.
WARNING: modpost: vmlinux.o(.text+0x551c): Section mismatch in reference from the function identical_pvr_fixup() to the function .init.text:identify_cpu() The function identical_pvr_fixup() references the function __init identify_cpu(). This is often because identical_pvr_fixup lacks a __init annotation or the annotation of identify_cpu is wrong.
identical_pvr_fixup() calls two functions marked as __init and is only called by a function marked as __init so it should be marked as __init as well. At the same time, remove the inline keywork as it is not necessary to inline this function. The compiler is still free to do so if it feels it is worthwhile since commit 889b3c1245de ("compiler: remove CONFIG_OPTIMIZE_INLINING entirely").

There are a few calls of usb_driver_claim_interface() but all of those miss the proper error checks, as reported by Coverity. This patch adds those missing checks.
Along with it, replace the magic pointer with -1 with a constant USB_AUDIO_IFACE_UNUSED for better readability.

The macro CN23XX_PEM_BAR1_INDEX_REG is being used to shift oct->pcie_port (a u16) left 24 places. There are two subtle issues here, first the shift gets promoted to an signed int and then sign extended to a u64. If oct->pcie_port is 0x80 or more then the upper bits get sign extended to 1. Secondly shfiting a u16 24 bits will lead to an overflow so it needs to be cast to a u64 for all the bits to not overflow.
It is entirely possible that the u16 port value is never large enough for this to fail, but it is useful to fix unintended overflows such as this.
Fix this by casting the port parameter to the macro to a u64 before the shift.

[ Upstream commit b8b2f37cf632434456182e9002d63cbc4cccc50c ]
When adding a PTE a ptesync is needed to order the update of the PTE with subsequent accesses otherwise a spurious fault may be raised.
radix__set_pte_at() does not do this for performance gains. For non-kernel memory this is not an issue as any faults of this kind are corrected by the page fault handler. For kernel memory these faults are not handled. The current solution is that there is a ptesync in flush_cache_vmap() which should be called when mapping from the vmalloc region.
However, map_kernel_page() does not call flush_cache_vmap(). This is troublesome in particular for code patching with Strict RWX on radix. In do_patch_instruction() the page frame that contains the instruction to be patched is mapped and then immediately patched. With no ordering or synchronization between setting up the PTE and writing to the page it is possible for faults.
As the code patching is done using __put_user_asm_goto() the resulting fault is obscured - but using a normal store instead it can be seen:

The power PMU group constraints includes check for EBB events to make sure all events in a group must agree on EBB. This will prevent scheduling EBB and non-EBB events together. But in the existing check, settings for constraint mask and value is interchanged. Patch fixes the same.
Before the patch, PMU selftest "cpu_event_pinned_vs_ebb_test" fails with below in dmesg logs. This happens because EBB event gets enabled along with a non-EBB cpu event.

If any of the cipher schemes specified by the driver are invalid, bail out and fail the registration rather than just warning. Otherwise, we might later crash when we try to use the invalid cipher scheme, e.g. if the hdr_len is (significantly) less than the pn_offs + pn_len, we'd have an out-of-bounds access in RX validation.

Currently the expression ~nic_conf1 is always true because nic_conf1 is a u16 and according to 6.5.3.3 of the C standard the ~ operator promotes the u16 to an integer before flipping all the bits. Thus the top 16 bits of the integer result are all set so the expression is always true. If the intention was to flip all the bits of nic_conf1 then casting the integer result back to a u16 is a suitabel fix.
Interestingly static analyzers seem to thing a bitwise ! should be used instead of ~ for this scenario, so I think the original intent of the expression may need some extra consideration.

The shifting of the u8 integers rq->caching by 26 bits to the left will be promoted to a 32 bit signed int and then sign-extended to a u64. In the event that rq->caching is greater than 0x1f then all then all the upper 32 bits of the u64 end up as also being set because of the int sign-extension. Fix this by casting the u8 values to a u64 before the 26 bit left shift.

The intel_gvt_init_vgpu_type_groups() function is only called from intel_gvt_init_device(). If it fails then the intel_gvt_init_device() prints the error code and propagates it back again. That's a bug because false is zero/success. The fix is to modify it to return zero or negative error codes and make everything consistent.

Mirror commit aeba3731b150 ("powerpc/pci: Fix IO space breakage after of_pci_range_to_resource() change").
Most MIPS platforms do not define PCI_IOBASE, nor implement pci_address_to_pio(). Moreover, IO_SPACE_LIMIT is 0xffff for most MIPS platforms. of_pci_range_to_resource passes the _start address_ of the IO range into pci_address_to_pio, which then checks it against IO_SPACE_LIMIT and fails, because for MIPS platforms that use pci-legacy (pci-lantiq, pci-rt3883, pci-mt7620), IO ranges start much higher than 0xffff.
In fact, pci-mt7621 in staging already works around this problem, see commit 09dd629eeabb ("staging: mt7621-pci: fix io space and properly set resource limits")
So just stop using of_pci_range_to_resource, which does not work for MIPS.

While adding the invalid IRQ check after calling platform_get_irq(), I managed to overlook that the driver has a complex error path in its probe() method, thus a simple *return* couldn't be used. Use a proper *goto* instead!

In mwl8k_probe_hw, hw->priv->txq is freed at the first time by dma_free_coherent() in the call chain: if(!priv->ap_fw)->mwl8k_init_txqs(hw)->mwl8k_txq_init(hw, i).
Then in err_free_queues of mwl8k_probe_hw, hw->priv->txq is freed at the second time by mwl8k_txq_deinit(hw, i)->dma_free_coherent().
My patch set txq->txd to NULL after the first free to avoid the double free.

VMCI feature is not supported in conjunction with the vSphere Fault Tolerance (FT) feature.
VMware Tools can repeatedly try to create a vsock connection. If FT is enabled the kernel logs is flooded with the following messages:
qp_alloc_hypercall result = -20 Could not attach to queue pair with -20
"qp_alloc_hypercall result = -20" was hidden by commit e8266c4c3307 ("VMCI: Stop log spew when qp allocation isn't possible"), but "Could not attach to queue pair with -20" is still there flooding the log.
Since the error message can be useful in some cases, print it only once.

When i40iw_hmc_sd_one fails, chunk is freed without the deletion of chunk entry in the PBLE info list.
Fix it by adding the chunk entry to the PBLE info list only after successful addition of SD in i40iw_hmc_sd_one.

Currently when the call to usb_urb_ep_type_check fails (returning -EINVAL) the error return path returns -ENOMEM via the exit label "error". Other uses of the same error exit label set the err variable to -ENOMEM but this is not being used. I believe the original intent was for the error exit path to return the value in err rather than the hard coded -ENOMEM, so return this rather than the hard coded -ENOMEM.

When the error check in ath9k_hw_read_revisions() was added, it checked for -EIO which is what ath9k_regread() in the ath9k_htc driver uses. However, for plain ath9k, the register read function uses ioread32(), which just returns -1 on error. So if such a read fails, it still gets passed through and ends up as a weird mac revision in the log output.
Fix this by changing ath9k_regread() to return -1 on error like ioread32() does, and fix the error check to look for that instead of -EIO.

The problem is that bnxt_show_temp() returns long but "rc" is an int and "len" is a u32. With ternary operations the type promotion is quite tricky. The negative "rc" is first promoted to u32 and then to long so it ends up being a high positive value instead of a a negative as we intended.
Fix this by removing the ternary.

Modify the header size check in geneve6_xmit_skb and geneve_xmit_skb to use pskb_inet_may_pull rather than pskb_network_may_pull. This fixes two kernel selftest failures introduced by the commit introducing the checks: IPv4 over geneve6: PMTU exceptions IPv4 over geneve6: PMTU exceptions - nexthop objects
It does this by correctly accounting for the fact that IPv4 packets may transit over geneve IPv6 tunnels (and vice versa), and still fixes the uninit-value bug fixed by the original commit.

In emac_mac_tx_buf_send, it calls emac_tx_fill_tpd(..,skb,..). If some error happens in emac_tx_fill_tpd(), the skb will be freed via dev_kfree_skb(skb) in error branch of emac_tx_fill_tpd(). But the freed skb is still used via skb->len by netdev_sent_queue(,skb->len).
As i observed that emac_tx_fill_tpd() haven't modified the value of skb->len, thus my patch assigns skb->len to 'len' before the possible free and use 'len' instead of skb->len later.

[ Upstream commit 926ee00ea24320052b46745ef4b00d91c05bd03d ]
The intent with this code was to return negative error codes but instead it returns positives.
The problem is how type promotion works with ternary operations. These functions return long, "ret" is an int and "copied" is a u32. The negative error code is first cast to u32 so it becomes a high positive and then cast to long where it's still a positive.
We could fix this by declaring "ret" as a ssize_t but let's just get rid of the ternaries instead.

commit 8d432592f30fcc34ef5a10aac4887b4897884493 upstream.
tcp_set_default_congestion_control() is netns-safe in that it writes to &net->ipv4.tcp_congestion_control, but it also sets ca->flags |= TCP_CONG_NON_RESTRICTED which is not namespaced. This has the unintended side-effect of changing the global net.ipv4.tcp_allowed_congestion_control sysctl, despite the fact that it is read-only: 97684f0970f6 ("net: Make tcp_allowed_congestion_control readonly in non-init netns")
Resolve this netns "leak" by only allowing the init netns to set the default algorithm to one that is restricted. This restriction could be removed if tcp_allowed_congestion_control were namespace-ified in the future.
This bug was uncovered with https://github.com/JonathonReinhart/linux-netns-sysctl-verify

commit 1139aeb1c521eb4a050920ce6c64c36c4f2a3ab7 upstream.
As of commit 966a967116e6 ("smp: Avoid using two cache lines for struct call_single_data"), the smp code prefers 32-byte aligned call_single_data objects for performance reasons, but the block layer includes an instance of this structure in the main 'struct request' that is more senstive to size than to performance here, see 4ccafe032005 ("block: unalign call_single_data in struct request").
The result is a violation of the calling conventions that clang correctly points out:
block/blk-mq.c:630:39: warning: passing 8-byte aligned argument to 32-byte aligned parameter 2 of 'smp_call_function_single_async' may result in an unaligned pointer access [-Walign-mismatch] smp_call_function_single_async(cpu, &rq->csd);
It does seem that the usage of the call_single_data without cache line alignment should still be allowed by the smp code, so just change the function prototype so it accepts both, but leave the default alignment unchanged for the other users. This seems better to me than adding a local hack to shut up an otherwise correct warning in the caller.

commit 01bfe5e8e428b475982a98a46cca5755726f3f7f upstream.
This reverts commit b166a20b07382b8bc1dcee2a448715c9c2c81b5b.
This one has to be reverted as it introduced a dead lock, as syzbot reported:
CPU0 CPU1 ---- ---- lock(&net->sctp.addr_wq_lock); lock(slock-AF_INET6); lock(&net->sctp.addr_wq_lock); lock(slock-AF_INET6);
CPU0 is the thread of sctp_addr_wq_timeout_handler(), and CPU1 is that of sctp_close().
The original issue this commit fixed will be fixed in the next patch.

commit 34e5b01186858b36c4d7c87e1a025071e8e2401f upstream.
As Or Cohen described:
If sctp_destroy_sock is called without sock_net(sk)->sctp.addr_wq_lock held and sp->do_auto_asconf is true, then an element is removed from the auto_asconf_splist without any proper locking.
This can happen in the following functions: 1. In sctp_accept, if sctp_sock_migrate fails. 2. In inet_create or inet6_create, if there is a bpf program attached to BPF_CGROUP_INET_SOCK_CREATE which denies creation of the sctp socket.
This patch is to fix it by moving the auto_asconf init out of sctp_init_sock(), by which inet_create()/inet6_create() won't need to operate it in sctp_destroy_sock() when calling sk_common_release().
It also makes more sense to do auto_asconf init while binding the first addr, as auto_asconf actually requires an ANY addr bind, see it in sctp_addr_wq_timeout_handler().
This addresses CVE-2021-23133.

The issue is that seq_read_iter() in fs/seq_file.c also needs an increment of the index in an non next record case as well which this patch fixes otherwise seq_read_iter() will print out the above message.

The Asus T100TAF uses the same jack-detect settings as the T100TA, this has been confirmed on actual hardware.
Add these settings to the T100TAF quirks to enable jack-detect support on the T100TAF.

Commit eaf4fac47807 ("net: stmmac: Do not accept invalid MTU values") started using the TX FIFO size to verify what counts as a valid MTU request for the stmmac driver. This is unset for the ipq806x variant. Looking at older patches for this it seems the RX + TXs buffers can be up to 8k, so set appropriately.
(I sent this as an RFC patch in June last year, but received no replies. I've been running with this on my hardware (a MikroTik RB3011) since then with larger MTUs to support both the internal qca8k switch and VLANs with no problems. Without the patch it's impossible to set the larger MTU required to support this.)

The buggy parameters currently get caught later, but emit a noisy WARN. Userspace should not be able to trigger this, so add similar checks much earlier. Also avoids some unneeded code paths, of course. Apply kernel coding stlye to a comment while here.

Currently l2cap_chan_set_defaults() reset chan->conf_state to zero. However, there is a flag CONF_NOT_COMPLETE which is set when creating the l2cap_chan. It is suggested that the flag should be cleared when l2cap_chan is ready, but when l2cap_chan_set_defaults() is called, l2cap_chan is not yet ready. Therefore, we must set this flag as the default.

Recently we had an interop issue where RARP packets got suppressed with bridge neigh suppression enabled, but the check in the code was meant to suppress GARP. Exclude RARP packets from it which would allow some VMWare setups to work, to quote the report: "Those RARP packets usually get generated by vMware to notify physical switches when vMotion occurs. vMware may use random sip/tip or just use sip=tip=0. So the RARP packet sometimes get properly flooded by the vtep and other times get dropped by the logic"

After adopting CONFIG_PCPU_DEV_REFCNT=n option, syzbot was able to trigger a warning [1]
Issue here is that:
- all dev_put() should be paired with a corresponding prior dev_hold().
- A driver doing a dev_put() in its ndo_uninit() MUST also do a dev_hold() in its ndo_init(), only when ndo_init() is returning 0.
Otherwise, register_netdevice() would call ndo_uninit() in its error path and release a refcount too soon.
Therefore, we need to move dev_hold() call from vti6_tnl_create2() to vti6_dev_init_gen()

After channel switch, we should consider any beacon with a CSA IE as a new switch. If the CSA IE is a leftover from before the switch that the AP forgot to remove, we'll get a CSA-to-Self.
This caused issues in iwlwifi where the firmware saw a beacon with a CSA-to-Self with mode = 1 on the new channel after a switch. The firmware considered this a new switch and closed its queues. Since the beacon didn't change between before and after the switch, we wouldn't handle it (the CRC is the same) and we wouldn't let the firmware open its queues again or disconnect if the CSA IE stays for too long.
Clear the CRC valid state after we switch to make sure that we handle the beacon and handle the CSA IE as required.

The Special Function Registers on all Exynos SoC, including ARM64, are 32-bit wide, so entire driver uses matching functions like readl() or writel(). On 64-bit ARM using unsigned long for register masks: 1. makes little sense as immediately after bitwise operation it will be cast to 32-bit value when calling writel(), 2. is actually error-prone because it might promote other operands to 64-bit.

If the user selects the very first entry in a page and performs a search-up operation, or selects the very last entry in a page and performs a search-down operation that will not succeed (e.g., via [/]asdfzzz[Up Arrow]), nconf will never terminate searching the page.
The reason is that in this case, the starting point will be set to -1 or n, which is then translated into (n - 1) (i.e., the last entry of the page) or 0 (i.e., the first entry of the page) and finally the search begins. This continues to work fine until the index reaches 0 or (n - 1), at which point it will be decremented to -1 or incremented to n, but not checked against the starting point right away. Instead, it's wrapped around to the bottom or top again, after which the starting point check occurs... and naturally fails.
My original implementation added another check for -1 before wrapping the running index variable around, but Masahiro Yamada pointed out that the actual issue is that the comparison point (starting point) exceeds bounds (i.e., the [0,n-1] interval) in the first place and that, instead, the starting point should be fixed.
This has the welcome side-effect of also fixing the case where the starting point was n while searching down, which also lead to an infinite loop.
OTOH, this code is now essentially all his work.
Amazingly, nobody seems to have been hit by this for 11 years - or at the very least nobody bothered to debug and fix this.

Some of the per-CPU masks use cpu_cpu_mask as a filter to limit the search for related CPUs. On a dlpar add of a CPU, update cpu_cpu_mask before updating the per-CPU masks. This will ensure the cpu_cpu_mask is updated correctly before its used in setting the masks. Setting the numa_node will ensure that when cpu_cpu_mask() gets called, the correct node number is used. This code movement helped fix the above call trace.

[ Upstream commit aa2f9c12821e6a4ba1df4fb34a3dbc6a2a1ee7fe ]
The ALC3263 codec on the XPS 13 9343 is also found on the Latitude 13 7350 and Venue 11 Pro 7140. They require the same handling for the combo jack to work with a headset: GPIO pin 6 must be set.
The HDA driver always sets this pin on the ALC3263, which it distinguishes by the codec vendor/device ID 0x10ec0288 and PCI subsystem vendor ID 0x1028 (Dell). The ASoC driver does not use PCI, so adapt this check to use DMI to determine if Dell is the system vendor.

[ Upstream commit c1d9e34e11281a8ba1a1c54e4db554232a461488 ]
Fix the following out-of-bounds warning:
net/ethtool/ioctl.c:492:2: warning: 'memcpy' offset [49, 84] from the object at 'link_usettings' is out of the bounds of referenced subobject 'base' with type 'struct ethtool_link_settings' at offset 0 [-Warray-bounds]
The problem is that the original code is trying to copy data into a some struct members adjacent to each other in a single call to memcpy(). This causes a legitimate compiler warning because memcpy() overruns the length of &link_usettings.base. Fix this by directly using &link_usettings and _from_ as destination and source addresses, instead.
This helps with the ongoing efforts to globally enable -Warray-bounds and get us closer to being able to tighten the FORTIFY_SOURCE routines on memcpy().

Fix the following out-of-bounds warnings by enclosing structure members daddr and saddr into new struct addr, in structures wl3501_md_req and wl3501_md_ind:
arch/x86/include/asm/string_32.h:182:25: warning: '__builtin_memcpy' offset [18, 23] from the object at 'sig' is out of the bounds of referenced subobject 'daddr' with type 'u8[6]' {aka 'unsigned char[6]'} at offset 11 [-Warray-bounds] arch/x86/include/asm/string_32.h:182:25: warning: '__builtin_memcpy' offset [18, 23] from the object at 'sig' is out of the bounds of referenced subobject 'daddr' with type 'u8[6]' {aka 'unsigned char[6]'} at offset 11 [-Warray-bounds]
Refactor the code, accordingly:

/* size: 24, cachelines: 1, members: 9 */ /* padding: 1 */ /* last cacheline: 24 bytes */ };
The problem is that the original code is trying to copy data into a couple of arrays adjacent to each other in a single call to memcpy(). Now that a new struct _addr_ enclosing those two adjacent arrays is introduced, memcpy() doesn't overrun the length of &sig.daddr[0] and &sig.daddr, because the address of the new struct object _addr_ is used, instead.
This helps with the ongoing efforts to globally enable -Warray-bounds and get us closer to being able to tighten the FORTIFY_SOURCE routines on memcpy().

The problem is that the original code is trying to copy data into a bunch of struct members adjacent to each other in a single call to memcpy(). Now that a new struct wl3501_req enclosing all those adjacent members is introduced, memcpy() doesn't overrun the length of &sig.beacon_period and &this->bss_set[i].beacon_period, because the address of the new struct object _req_ is used as the destination, instead.
This helps with the ongoing efforts to globally enable -Warray-bounds and get us closer to being able to tighten the FORTIFY_SOURCE routines on memcpy().

[ Upstream commit cc7130bf119add37f36238343a593b71ef6ecc1e ]
The IOMMU table is divided into pools for concurrent mappings and each pool has a separate spinlock. When taking the ownership of an IOMMU group to pass through a device to a VM, we lock these spinlocks which triggers a false negative warning in lockdep (below).
This fixes it by annotating the large pool's spinlock as a nest lock which makes lockdep not complaining when locking nested locks if the nest lock is locked already.

Noticed failure as a crash on ia64 when tried to symbolize all backtraces collected by page_owner=on:
$ cat /sys/kernel/debug/page_owner <oops>
CPU: 1 PID: 2074 Comm: cat Not tainted 5.12.0-rc4 #226 Hardware name: hp server rx3600, BIOS 04.03 04/08/2008 ip is at dereference_module_function_descriptor+0x41/0x100
Crash happens at dereference_module_function_descriptor() due to use-after-free when dereferencing ".opd" section header.
All section headers are already freed after module is laoded successfully.
To keep symbolizer working the change stores ".opd" address and size after module is relocated to a new place and before section headers are discarded.
To make similar errors less obscure module_finalize() now zeroes out all variables relevant to module loading only.

The commit 1879445dfa7b ("perf/core: Set event's default ::overflow_handler()") set a default event->overflow_handler in perf_event_alloc(), and replace the check event->overflow_handler with is_default_overflow_handler(), but one is missing.
Currently, the bp->overflow_handler can not be NULL. As a result, enable_single_step() is always not invoked.

We (adam zabrocki, alexander matrosov, alexander tereshkin, maksym bazalii) observed the check:
if (fh->size > sizeof(struct nfs_fh))
should not use the size of the nfs_fh struct which includes an extra two bytes from the size field.
struct nfs_fh { unsigned short size; unsigned char data[NFS_MAXFHSIZE]; }
but should determine the size from data[NFS_MAXFHSIZE] so the memcpy will not write 2 bytes beyond destination. The proposed fix is to compare against the NFS_MAXFHSIZE directly, as is done elsewhere in fs code base.

Currently the client ignores the value of the sr_eof of the SEEK operation. According to the spec, if the server didn't find the requested extent and reached the end of the file, the server would return sr_eof=true. In case the request for DATA and no data was found (ie in the middle of the hole), then the lseek expects that ENXIO would be returned.

This is caused by a transport use-after-free issue. When processing a duplicate COOKIE-ECHO chunk in sctp_sf_do_dupcook_a(), both COOKIE-ACK and SHUTDOWN chunks are allocated with the transort from the new asoc. However, later in the sideeffect machine, the old asoc is used to send them out and old asoc's shutdown_last_sent_to is set to the transport that SHUTDOWN chunk attached to in sctp_cmd_setup_t2(), which actually belongs to the new asoc. After the new_asoc is freed and the old asoc T2 timeout, the old asoc's shutdown_last_sent_to that is already freed would be accessed in sctp_sf_t2_timer_expire().
Thanks Alexander and Jere for helping dig into this issue.
To fix it, this patch is to do the asoc update first, then allocate the COOKIE-ACK and SHUTDOWN chunks with the 'updated' old asoc. This would make more sense, as a chunk from an asoc shouldn't be sent out with another asoc. We had fixed quite a few issues caused by this.

[ Upstream commit f282df0391267fb2b263da1cc3233aa6fb81defc ]
Normally SCTP_MIB_CURRESTAB is always incremented once asoc enter into ESTABLISHED from the state < ESTABLISHED and decremented when the asoc is being deleted.
However, in sctp_sf_do_dupcook_b(), the asoc's state can be changed to ESTABLISHED from the state >= ESTABLISHED where it shouldn't increment SCTP_MIB_CURRESTAB. Otherwise, one asoc may increment MIB_CURRESTAB multiple times but only decrement once at the end.
I was able to reproduce it by using scapy to do the 4-way shakehands, after that I replayed the COOKIE-ECHO chunk with 'peer_vtag' field changed to different values, and SCTP_MIB_CURRESTAB was incremented multiple times and never went back to 0 even when the asoc was freed.
This patch is to fix it by only incrementing SCTP_MIB_CURRESTAB when the state < ESTABLISHED in sctp_sf_do_dupcook_b().

When removing rmap_item from stable tree, STABLE_FLAG of rmap_item is cleared with head reserved. So the following scenario might happen: For ksm page with rmap_item1:
cmp_and_merge_page stable_node->head = &migrate_nodes; remove_rmap_item_from_tree, but head still equal to stable_node; try_to_merge_with_ksm_page failed; return;
For the same ksm page with rmap_item2, stable node migration succeed this time. The stable_node->head does not equal to migrate_nodes now. For ksm page with rmap_item1 again:
cmp_and_merge_page stable_node->head != &migrate_nodes && rmap_item->head == stable_node return;
We would miss the rmap_item for stable_node and might result in failed rmap_walk_ksm(). Fix this by set rmap_item->head to NULL when rmap_item is removed from stable tree.

syzbot is able to setup kTLS on an SMC socket which coincidentally uses sk_user_data too. Later, kTLS treats it as psock so triggers a refcnt warning. The root cause is that smc_setsockopt() simply calls TCP setsockopt() which includes TCP_ULP. I do not think it makes sense to setup kTLS on top of SMC sockets, so we should just disallow this setup.
It is hard to find a commit to blame, but we can apply this patch since the beginning of TCP_ULP.

[ Upstream commit 0258bdfaff5bd13c4d2383150b7097aecd6b6d82 ]
This fixes an issue where old load on a cfs_rq is not properly decayed, resulting in strange behavior where fairness can decrease drastically. Real workloads with equally weighted control groups have ended up getting a respective 99% and 1%(!!) of cpu time.
When an idle task is attached to a cfs_rq by attaching a pid to a cgroup, the old load of the task is attached to the new cfs_rq and sched_entity by attach_entity_cfs_rq. If the task is then moved to another cpu (and therefore cfs_rq) before being enqueued/woken up, the load will be moved to cfs_rq->removed from the sched_entity. Such a move will happen when enforcing a cpuset on the task (eg. via a cgroup) that force it to move.
The load will however not be removed from the task_group itself, making it look like there is a constant load on that cfs_rq. This causes the vruntime of tasks on other sibling cfs_rq's to increase faster than they are supposed to; causing severe fairness issues. If no other task is started on the given cfs_rq, and due to the cpuset it would not happen, this load would never be properly unloaded. With this patch the load will be properly removed inside update_blocked_averages. This also applies to tasks moved to the fair scheduling class and moved to another cpu, and this path will also fix that. For fork, the entity is queued right away, so this problem does not affect that.
This applies to cases where the new process is the first in the cfs_rq, issue introduced 3d30544f0212 ("sched/fair: Apply more PELT fixes"), and when there has previously been load on the cgroup but the cgroup was removed from the leaflist due to having null PELT load, indroduced in 039ae8bcf7a5 ("sched/fair: Fix O(nr_cgroups) in the load balancing path").
For a simple cgroup hierarchy (as seen below) with two equally weighted groups, that in theory should get 50/50 of cpu time each, it often leads to a load of 60/40 or 70/30.
parent/ cg-1/ cpu.weight: 100 cpuset.cpus: 1 cg-2/ cpu.weight: 100 cpuset.cpus: 1
If the hierarchy is deeper (as seen below), while keeping cg-1 and cg-2 equally weighted, they should still get a 50/50 balance of cpu time. This however sometimes results in a balance of 10/90 or 1/99(!!) between the task groups.
$ ps u -C stress USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 18568 1.1 0.0 3684 100 pts/12 R+ 13:36 0:00 stress --cpu 1 root 18580 99.3 0.0 3684 100 pts/12 R+ 13:36 0:09 stress --cpu 1

This can be reproduced by attaching an idle process to a cgroup and moving it to a given cpuset before it wakes up. The issue is evident in many (if not most) container runtimes, and has been reproduced with both crun and runc (and therefore docker and all its "derivatives"), and with both cgroup v1 and v2.

commit 3433adc8bd09fc9f29b8baddf33b4ecd1ecd2cdc upstream.
We have NR_syscall syscalls from [0 .. NR_syscall-1]. However the check for invalid syscall number is "> NR_syscall" as opposed to >=. This off-by-one error erronesously allows "NR_syscall" to be treated as valid syscall causeing out-of-bounds access into syscall-call table ensuing a crash (holes within syscall table have a invalid-entry handler but this is beyond the array implementing the table).
This problem showed up on v5.6 kernel when testing glibc 2.33 (v5.10 kernel capable, includng faccessat2 syscall 439). The v5.6 kernel has NR_syscalls=439 (0 to 438). Due to the bug, 439 passed by glibc was not handled as -ENOSYS but processed leading to a crash.

commit 8ec7791bae1327b1c279c5cd6e929c3b12daaf0a upstream.
The STF (store-to-load forwarding) barrier mitigation can be enabled/disabled at runtime via a debugfs file (stf_barrier), which causes the kernel to patch itself to enable/disable the relevant mitigations.
However depending on which mitigation we're using, it may not be safe to do that patching while other CPUs are active. For example the following crash:

Shows that we returned to userspace without restoring the user r13 value, due to executing the partially patched STF exit code.
Fix it by doing the patching under stop machine. The CPUs that aren't doing the patching will be spinning in the core of the stop machine logic. That is currently sufficient for our purposes, because none of the patching we do is to that code or anywhere in the vicinity.

commit c3187cf32216313fb316084efac4dab3a8459b1d upstream.
I believe there are some issues introduced by commit 31651c607151 ("hfsplus: avoid deadlock on file truncation")
HFS+ has extent records which always contains 8 extents. In case the first extent record in catalog file gets full, new ones are allocated from extents overflow file.
In case shrinking truncate happens to middle of an extent record which locates in extents overflow file, the logic in hfsplus_file_truncate() was changed so that call to hfs_brec_remove() is not guarded any more.
Right action would be just freeing the extents that exceed the new size inside extent record by calling hfsplus_free_extents(), and then check if the whole extent record should be removed. However since the guard (blk_cnt > start) is now after the call to hfs_brec_remove(), this has unfortunate effect that the last matching extent record is removed unconditionally.
To reproduce this issue, create a file which has at least 10 extents, and then perform shrinking truncate into middle of the last extent record, so that the number of remaining extents is not under or divisible by 8. This causes the last extent record (8 extents) to be removed totally instead of truncating into middle of it. Thus this causes corruption, and lost data.
Fix for this is simply checking if the new truncated end is below the start of this extent record, making it safe to remove the full extent record. However call to hfs_brec_remove() can't be moved to it's previous place since we're dropping ->tree_lock and it can cause a race condition and the cached info being invalidated possibly corrupting the node data.
Another issue is related to this one. When entering into the block (blk_cnt > start) we are not holding the ->tree_lock. We break out from the loop not holding the lock, but hfs_find_exit() does unlock it. Not sure if it's possible for someone else to take the lock under our feet, but it can cause hard to debug errors and premature unlocking. Even if there's no real risk of it, the locking should still always be kept in balance. Thus taking the lock now just before the check.

commit d6e621de1fceb3b098ebf435ef7ea91ec4838a1a upstream.
Sysbot has reported a "divide error" which has been identified as being caused by a corrupted file_size value within the file inode. This value has been corrupted to a much larger value than expected.
Calculate_skip() is passed i_size_read(inode) >> msblk->block_log. Due to the file_size value corruption this overflows the int argument/variable in that function, leading to the divide error.
This patch changes the function to use u64. This will accommodate any unexpectedly large values due to corruption.
The value returned from calculate_skip() is clamped to be never more than SQUASHFS_CACHED_BLKS - 1, or 7. So file_size corruption does not lead to an unexpectedly large return result here.

commit 7ed9d238c7dbb1fdb63ad96a6184985151b0171c upstream.
Consider the following sequence of events:
1. Userspace issues a UFFD ioctl, which ends up calling into shmem_mfill_atomic_pte(). We successfully account the blocks, we shmem_alloc_page(), but then the copy_from_user() fails. We return -ENOENT. We don't release the page we allocated. 2. Our caller detects this error code, tries the copy_from_user() after dropping the mmap_lock, and retries, calling back into shmem_mfill_atomic_pte(). 3. Meanwhile, let's say another process filled up the tmpfs being used. 4. So shmem_mfill_atomic_pte() fails to account blocks this time, and immediately returns - without releasing the page.
This triggers a BUG_ON in our caller, which asserts that the page should always be consumed, unless -ENOENT is returned.
To fix this, detect if we have such a "dangling" page when accounting fails, and if so, release it before returning.

commit 227545b9a08c68778ddd89428f99c351fc9315ac upstream.
Screen flickers rapidly when two 4K 60Hz monitors are in use. This issue doesn't happen when one monitor is 4K 60Hz (pixelclock 594MHz) and another one is 4K 30Hz (pixelclock 297MHz).
The issue is gone after setting "power_dpm_force_performance_level" to "high". Following the indication, we found that the issue occurs when sclk is too low.
So resolve the issue by disabling sclk switching when there are two monitors requires high pixelclock (> 297MHz).

commit e17b02d4970913233d543c79c9c66e72cac05bdd upstream.
When extcon is used in combination with dwc3, it is assumed that the dwc3 registers are untouched and as such are only configured if VBUS is valid or ID is tied to ground.
In case VBUS is not valid or ID is floating, the registers are not configured as such during driver initialization, causing a wrong default state during boot.
If the registers are not in a default state, because they are for instance touched by a boot loader, this can cause for a kernel error.

commit 75a41ce46bae6cbe7d3bb2584eb844291d642874 upstream.
The dwc2 gadget support maps and unmaps DMA buffers as necessary. When mapping and unmapping it uses the direction of the endpoint to select the direction of the DMA transfer, but this fails for Control OUT transfers because the unmap occurs after the endpoint direction has been reversed for the status phase.
A possible solution would be to unmap the buffer before the direction is changed, but a safer, less invasive fix is to remember the buffer direction independently of the endpoint direction.

commit dda32c00c9a0fa103b5d54ef72c477b7aa993679 upstream.
'xhci_urb_enqueue()' is passed a 'mem_flags' argument, because "URBs may be submitted in interrupt context" (see comment related to 'usb_submit_urb()' in 'drivers/usb/core/urb.c')
So this flag should be used in all the calling chain. Up to now, 'xhci_check_maxpacket()' which is only called from 'xhci_urb_enqueue()', uses GFP_KERNEL.
Be safe and pass the mem_flags to this function as well.

commit 193ced4a79599352d63cb8c9e2f0c6043106eb6a upstream.
Recent versions of the PCI Express specification have deprecated support for I/O transactions and actually some PCIe host bridges, such as Power Systems Host Bridge 4 (PHB4), do not implement them.
The default kernel configuration choice for the defxx driver is the use of I/O ports rather than MMIO for PCI and EISA systems. It may have made sense as a conservative backwards compatible choice back when MMIO operation support was added to the driver as a part of TURBOchannel bus support. However nowadays this configuration choice makes the driver unusable with systems that do not implement I/O transactions for PCIe.
Make DEFXX_MMIO the configuration default then, except where configured for EISA. This exception is because an EISA adapter can have its MMIO decoding disabled with ECU (EISA Configuration Utility) and therefore not available with the resource allocation infrastructure we implement, while port I/O is always readily available as it uses slot-specific addressing, directly mapped to the slot an option card has been placed in and handled with our EISA bus support core. Conversely a kernel that supports modern systems which may not have I/O transactions implemented for PCIe will usually not be expected to handle legacy EISA systems.
The change of the default will make it easier for people, including but not limited to distribution packagers, to make a working choice for the driver.
Update the option description accordingly and while at it replace the potentially ambiguous PIO acronym with IOP for "port I/O" vs "I/O ports" according to our nomenclature used elsewhere.

commit c49f71f60754acbff37505e1d16ca796bf8a8140 upstream.
Our current MIPS platform `__div64_32' handler is inactive, because it is incorrectly only enabled for 64-bit configurations, for which generic `do_div' code does not call it anyway.
The handler is not suitable for being called from there though as it only calculates 32 bits of the quotient under the assumption the 64-bit divident has been suitably reduced. Code for such reduction used to be there, however it has been incorrectly removed with commit c21004cd5b4c ("MIPS: Rewrite <asm/div64.h> to work with gcc 4.4.0."), which should have only updated an obsoleted constraint for an inline asm involving $hi and $lo register outputs, while possibly wiring the original MIPS variant of the `do_div' macro as `__div64_32' handler for the generic `do_div' implementation
Correct the handler as follows then:
- Revert most of the commit referred, however retaining the current formatting, except for the final two instructions of the inline asm sequence, which the original commit missed. Omit the original 64-bit parts though.
- Rename the original `do_div' macro to `__div64_32'. Use the combined `x' constraint referring to the MD accumulator as a whole, replacing the original individual `h' and `l' constraints used for $hi and $lo registers respectively, of which `h' has been obsoleted with GCC 4.4. Update surrounding code accordingly.
We have since removed support for GCC versions before 4.9, so no need for a special arrangement here; GCC has supported the `x' constraint since forever anyway, or at least going back to 1991.
- Rename the `__base' local variable in `__div64_32' to `__radix' to avoid a conflict with a local variable in `do_div'.
- Actually enable this code for 32-bit rather than 64-bit configurations by qualifying it with BITS_PER_LONG being 32 instead of 64. Include <asm/bitsperlong.h> for this macro rather than <linux/types.h> as we don't need anything else.
- Finally include <asm-generic/div64.h> last rather than first.
This has passed correctness verification with test_div64 and reduced the module's average execution time down to 1.0668s and 0.2629s from 2.1529s and 0.5647s respectively for an R3400 CPU @40MHz and a 5Kc CPU @160MHz. For a reference 64-bit `do_div' code where we have the DDIVU instruction available to do the whole calculation right away averages at 0.0660s for the latter CPU.

commit c1d337d45ec0a802299688e17d568c4e3a585895 upstream.
We already check the high part of the divident against zero to avoid the costly DIVU instruction in that case, needed to reduce the high part of the divident, so we may well check against the divisor instead and set the high part of the quotient to zero right away. We need to treat the high part the divident in that case though as the remainder that would be calculated by the DIVU instruction we avoided.

commit 25ab14cbe9d1b66fda44c71a2db7582a31b6f5cd upstream.
Remove the inline asm with a DIVU instruction from `__div64_32' and use plain C code for the intended DIVMOD calculation instead. GCC is smart enough to know that both the quotient and the remainder are calculated with single DIVU, so with ISAs up to R5 the same instruction is actually produced with overall similar code.
For R6 compiled code will work, but separate DIVU and MODU instructions will be produced, which are also interlocked, so scalar implementations will likely not perform as well as older ISAs with their asynchronous MD unit. Likely still faster then the generic algorithm though.
This removes a compilation error for R6 however where the original DIVU instruction is not supported anymore and the MDU accumulator registers have been removed and consequently GCC complains as to a constraint it cannot find a register for:

commit fef05776eb02238dcad8d5514e666a42572c3f32 upstream.
The tz->lock must be hold during the looping over the instances in that thermal zone. This lock was missing in the governor code since the beginning, so it's hard to point into a particular commit.

commit b4104180a2efb85f55e1ba1407885c9421970338 upstream.
syzbot can trigger the WARN() in init_uevent_argv() which isn't the nicest as the code does properly recover and handle the error. So change the WARN() call to pr_warn() and provide some more information on what the buffer size that was needed.

commit 2671fa4dc0109d3fb581bc3078fdf17b5d9080f6 upstream.
These sysctls point to global variables: - NF_SYSCTL_CT_MAX (&nf_conntrack_max) - NF_SYSCTL_CT_EXPECT_MAX (&nf_ct_expect_max) - NF_SYSCTL_CT_BUCKETS (&nf_conntrack_htable_size_user)
Because their data pointers are not updated to point to per-netns structures, they must be marked read-only in a non-init_net ns. Otherwise, changes in any net namespace are reflected in (leaked into) all other net namespaces. This problem has existed since the introduction of net namespaces.
The current logic marks them read-only only if the net namespace is owned by an unprivileged user (other than init_user_ns).
Commit d0febd81ae77 ("netfilter: conntrack: re-visit sysctls in unprivileged namespaces") "exposes all sysctls even if the namespace is unpriviliged." Since we need to mark them readonly in any case, we can forego the unprivileged user check altogether.

commit 34138a59b92c1a30649a18ec442d2e61f3bc34dd upstream.
This clock must be always enabled to allow access to any registers in fsys1 CMU. Until proper solution based on runtime PM is applied (similar to what was done for Exynos5433), mark that clock as critical so it won't be disabled.
It was observed on Samsung Galaxy S6 device (based on Exynos7420), where UFS module is probed before pmic used to power that device. In this case defer probe was happening and that clock was disabled by UFS driver, causing whole boot to hang on next CMU access.

[ Upstream commit d6d43a92172085a2681e06a0d06aac53c7bcdd12 ]
In the second loop of ingenic_pinconf_set(), it annotates the switch default case as unreachable(). The annotation is technically correct, because that same case would have resulted in an early function return in the previous loop.
However, the compiled code is suboptimal. GCC seems to work extra hard to ensure that the unreachable code path triggers undefined behavior. The function would fall through to start executing whatever function happens to be next in the compilation unit.
This is problematic because:
a) it adds unnecessary 'ensure undefined behavior' logic, and corresponding i-cache footprint; and
b) it's less robust -- if a bug were to be introduced, falling through to the next function would be catastrophic.
Yet another issue is that, while objtool normally understands unreachable() annotations, there's one special case where it doesn't: when the annotation occurs immediately after a 'ret' instruction. That happens to be the case here because unreachable() is immediately before the return.
Remove the unreachable() annotation and replace it with a comment. This simplifies the code generation and changes the unreachable error path to just silently return instead of corrupting execution.
This fixes the following objtool warning:
drivers/pinctrl/pinctrl-ingenic.o: warning: objtool: ingenic_pinconf_set() falls through to next function ingenic_pinconf_group_set()

In order to set the correct return flags for poll, the xsk code has to check if the Rx queue is empty and if the Tx queue is full. This code was unnecessarily large and complex as it used the functions that are used to update the local state from the global state (xskq_nb_free and xskq_nb_avail). Since we are not doing this nor updating any data dependent on this state, we can simplify the functions. Another benefit from this is that we can also simplify the xskq_nb_free and xskq_nb_avail functions in a later commit.

The cache invalidation code in v7_invalidate_l1 can be tweaked to re-read the associativity from CCSIDR, and keep the way identifier component in a single register that is assigned in the outer loop. This way, we need 2 registers less.
Given that the number of sets is typically much larger than the associativity, rearrange the code so that the outer loop has the fewer number of iterations, ensuring that the re-read of CCSIDR only occurs a handful of times in practice.
Fix the whitespace while at it, and update the comment to indicate that this code is no longer a clone of anything else.

[ Upstream commit 8252ca87c7a2111502ee13994956f8c309faad7f ]
Enabling function_graph tracer on ARM causes kernel panic, because the function graph tracer updates the "return address" of a function in order to insert a trace callback on function exit, it saves the function's original return address in a return trace stack, but cpu_suspend() may not return through the normal return path.
cpu_suspend() will resume directly via the cpu_resume path, but the return trace stack has been set-up by the subfunctions of cpu_suspend(), which makes the "return address" inconsistent with cpu_suspend().
This patch refers to Commit de818bd4522c40ea02a81b387d2fa86f989c9623 ("arm64: kernel: pause/unpause function graph tracer in cpu_suspend()"),
fixes the issue by pausing/resuming the function graph tracer on the thread executing cpu_suspend(), so that the function graph tracer state is kept consistent across functions that enter power down states and never return by effectively disabling graph tracer while they are executing.

In enable_slot(), if pci_get_slot() returns NULL, we clear the SLOT_ENABLED flag. When pci_get_slot() finds a device, it increments the device's reference count. In this case, we did not call pci_dev_put() to decrement the reference count, so the memory of the device (struct pci_dev type) will eventually leak.
Call pci_dev_put() to decrement its reference count when pci_get_slot() returns a PCI device.

Despite these errors, the elants_i2c driver stays bound to the device (it returns 0 from its probe method despite the errors), blocking the i2c-hid driver from binding.
Manually unbinding the elants_i2c driver and binding the i2c-hid driver makes the touchscreen work.
Check if the ACPI-fwnode for the touchscreen contains one of the i2c-hid compatiblity-id strings and if it has the I2C-HID spec's DSM to get the HID descriptor address, If it has both then make elants_i2c not bind, so that the i2c-hid driver can bind.
This assumes that non of the (older) elan touchscreens which actually need the elants_i2c driver falsely advertise an i2c-hid compatiblity-id + DSM in their ACPI-fwnodes. If some of them actually do have this false advertising, then this change may lead to regressions.
While at it also drop the unnecessary DEVICE_NAME prefixing of the "I2C check functionality error", dev_err already outputs the driver-name.

[ Upstream commit e479187748a8f151a85116a7091c599b121fdea5 ]
Some buggy BIOS-es bring up the touchscreen-controller in a stuck state where it blocks the I2C bus. Specifically this happens on the Jumper EZpad 7 tablet model.
After much poking at this problem I have found that the following steps are necessary to unstuck the chip / bus:
1. Turn off the Silead chip. 2. Try to do an I2C transfer with the chip, this will fail in response to which the I2C-bus-driver will call: i2c_recover_bus() which will unstuck the I2C-bus. Note the unstuck-ing of the I2C bus only works if we first drop the chip of the bus by turning it off. 3. Turn the chip back on.
On the x86/ACPI systems were this problem is seen, step 1. and 3. require making ACPI calls and dealing with ACPI Power Resources. This commit adds a workaround which runtime-suspends the chip to turn it off, leaving it up to the ACPI subsystem to deal with all the ACPI specific details.
There is no good way to detect this bug, so the workaround gets activated by a new "silead,stuck-controller-bug" boolean device-property. Since this is only used on x86/ACPI, this will be set by model specific device-props set by drivers/platform/x86/touchscreen_dmi.c. Therefor this new device-property is not documented in the DT-bindings.
Dmesg will contain the following messages on systems where the workaround is activated:

indicating that the UML function openpty_cb() calls openpty(), which internally calls __getgrnam_r(), which causes the nsswitch machinery to get started.
This loads, through lots of indirection that I snipped, the libcom_err.so.2 library, which (in an unknown function, "??") calls sem_init().
Now, of course it wants to get libpthread's sem_init(), since it's linked against libpthread. However, the dynamic linker looks up that symbol against the binary first, and gets the kernel's sem_init().
Hajime Tazaki noted that "objcopy -L" can localize a symbol, so the dynamic linker wouldn't do the lookup this way. I tried, but for some reason that didn't seem to work.
Doing the same thing in the linker script instead does seem to work, though I cannot entirely explain - it *also* works if I just add "VERSION { { global: *; }; }" instead, indicating that something else is happening that I don't really understand. It may be that explicitly doing that marks them with some kind of empty version, and that's different from the default.
Explicitly marking them with a version breaks kallsyms, so that doesn't seem to be possible.
Marking all the symbols as local seems correct, and does seem to address the issue, so do that. Also do it for static link, nsswitch libraries could still be loaded there.

[ Upstream commit 57ac51667d8cd62731223d687e5fe7b41c502f89 ]
On Qualcomm ARM32 platforms, the SMC call can return before it has completed. If this occurs, the call can be restarted, but it requires using the returned session ID value from the interrupted SMC call.
The ARM32 SMCC code already has the provision to add platform specific quirks for things like this. So let's make use of it and add the Qualcomm specific quirk (ARM_SMCCC_QUIRK_QCOM_A6) used by the QCOM_SCM driver.
This change is similar to the below one added for ARM64 a while ago: commit 82bcd087029f ("firmware: qcom: scm: Fix interrupted SCM calls")
Without this change, the Qualcomm ARM32 platforms like SDX55 will return -EINVAL for SMC calls used for modem firmware loading and validation.

Clang can generate R_RISCV_CALL_PLT relocations to _mcount:
$ llvm-objdump -dr build/riscv/init/main.o | rg mcount 000000000000000e: R_RISCV_CALL_PLT _mcount 000000000000004e: R_RISCV_CALL_PLT _mcount
After this, the __start_mcount_loc section is properly generated and function tracing still works.

[ Upstream commit 7ce04771503074a7de7f539cc43f5e1b385cb99b ]
Prior to clang 13.0.0, the RISC-V name for the mcount symbol was "mcount", which differs from the GCC version of "_mcount", which results in the following errors:
riscv64-linux-gnu-ld: init/main.o: in function `__traceiter_initcall_level': main.c:(.text+0xe): undefined reference to `mcount' riscv64-linux-gnu-ld: init/main.o: in function `__traceiter_initcall_start': main.c:(.text+0x4e): undefined reference to `mcount' riscv64-linux-gnu-ld: init/main.o: in function `__traceiter_initcall_finish': main.c:(.text+0x92): undefined reference to `mcount' riscv64-linux-gnu-ld: init/main.o: in function `.LBB32_28': main.c:(.text+0x30c): undefined reference to `mcount' riscv64-linux-gnu-ld: init/main.o: in function `free_initmem': main.c:(.text+0x54c): undefined reference to `mcount'
This has been corrected in https://reviews.llvm.org/D98881 but the minimum supported clang version is 10.0.1. To avoid build errors and to gain a working function tracer, adjust the name of the mcount symbol for older versions of clang in mount.S and recordmcount.pl.

If tcmu_handle_completions() finds an invalid cmd_id while looping over cmd responses from userspace it sets TCMU_DEV_BIT_BROKEN and breaks the loop. This means that it does further handling for the tcmu device.
Skip that handling by replacing 'break' with 'return'.
Additionally change tcmu_handle_completions() from unsigned int to bool, since the value used in return already is bool.

Like some other Bay and Cherry Trail SoC based devices the Dell Venue 10 Pro 5055 has an embedded-controller which uses ACPI GPIO events to report events instead of using the standard ACPI EC interface for this.
The EC interrupt is only used to report battery-level changes and it keeps doing this while the system is suspended, causing the system to not stay suspended.
Add an ignore-wake quirk for the GPIO pin used by the EC to fix the spurious wakeups from suspend.

Without this change, the DAC ctl's name could be changed only when the machine has both Speaker and Headphone, but we met some machines which only has Lineout and Headhpone, and the Lineout and Headphone share the Audio Mixer0 and DAC0, the ctl's name is set to "Front".
On most of machines, the "Front" is used for Speaker only or Lineout only, but on this machine it is shared by Lineout and Headphone, This introduces an issue in the pipewire and pulseaudio, suppose users want the Headphone to be on and the Speaker/Lineout to be off, they could turn off the "Front", this works on most of the machines, but on this machine, the "Front" couldn't be turned off otherwise the headphone will be off too. Here we do some change to let the ctl's name change to "Headphone+LO" on this machine, and pipewire and pulseaudio already could handle "Headphone+LO" and "Speaker+LO".

blkdev_read_iter can truncate iov_iter's count since the count + pos may exceed the size of the blkdev. This will confuse io_read that we have consume the iovec. And once we do the iov_iter_revert in io_read, we will trigger the slab-out-of-bounds. Fix it by reexpand the count with size has been truncated.
blkdev_write_iter can trigger the problem too.

[ Upstream commit 8a7cb245cf28cb3e541e0d6c8624b95d079e155b ]
The RX FIFO overflows when the system is not able to process all received packets and they start accumulating (first in the DMA queue in memory, then in the FIFO). An interrupt is then raised for each overflowing packet and handled in stmmac_interrupt(). This is counter-productive, since it brings the system (or more likely, one CPU core) to its knees to process the FIFO overflow interrupts.
stmmac_interrupt() handles overflow interrupts by writing the rx tail ptr into the corresponding hardware register (according to the MAC spec, this has the effect of restarting the MAC DMA). However, without freeing any rx descriptors, the DMA stops right away, and another overflow interrupt is raised as the FIFO overflows again. Since the DMA is already restarted at the end of stmmac_rx_refill() after freeing descriptors, disabling FIFO overflow interrupts and the corresponding handling code has no side effect, and eliminates the interrupt storm when the RX FIFO overflows.

commit 7f700334be9aeb91d5d86ef9ad2d901b9b453e9b upstream.
After adopting CONFIG_PCPU_DEV_REFCNT=n option, syzbot was able to trigger a warning [1]
Issue here is that:
- all dev_put() should be paired with a corresponding dev_hold(), and vice versa.
- A driver doing a dev_put() in its ndo_uninit() MUST also do a dev_hold() in its ndo_init(), only when ndo_init() is returning 0.
Otherwise, register_netdevice() would call ndo_uninit() in its error path and release a refcount too soon.
ip6_gre for example (among others problematic drivers) has to use dev_hold() in ip6gre_tunnel_init_common() instead of from ip6gre_newlink_common(), covering both ip6gre_tunnel_init() and ip6gre_tap_init()/
Note that ip6gre_tunnel_init_common() is not called from ip6erspan_tap_init() thus we also need to add a dev_hold() there, as ip6erspan_tunnel_uninit() does call dev_put()

commit 0d7a7b2014b1a499a0fe24c9f3063d7856b5aaaf upstream.
My previous commits added a dev_hold() in tunnels ndo_init(), but forgot to remove it from special functions setting up fallback tunnels.
Fallback tunnels do call their respective ndo_init()
This leads to various reports like :
unregister_netdevice: waiting for ip6gre0 to become free. Usage count = 2

From: Alexandru Elisei alexandru.elisei@arm.com
commit 263d6287da1433aba11c5b4046388f2cdf49675c upstream.
When a VCPU is created, the kvm_vcpu struct is initialized to zero in kvm_vm_ioctl_create_vcpu(). On VHE systems, the first time vcpu.arch.mdcr_el2 is loaded on hardware is in vcpu_load(), before it is set to a sensible value in kvm_arm_setup_debug() later in the run loop. The result is that KVM executes for a short time with MDCR_EL2 set to zero.
This has several unintended consequences:
* Setting MDCR_EL2.HPMN to 0 is constrained unpredictable according to ARM DDI 0487G.a, page D13-3820. The behavior specified by the architecture in this case is for the PE to behave as if MDCR_EL2.HPMN is set to a value less than or equal to PMCR_EL0.N, which means that an unknown number of counters are now disabled by MDCR_EL2.HPME, which is zero.
* The host configuration for the other debug features controlled by MDCR_EL2 is temporarily lost. This has been harmless so far, as Linux doesn't use the other fields, but that might change in the future.
Let's avoid both issues by initializing the VCPU's mdcr_el2 field in kvm_vcpu_vcpu_first_run_init(), thus making sure that the MDCR_EL2 register has a consistent value after each vcpu_load().

Some distributions are about to switch to Python 3 support only. This means that /usr/bin/python, which is Python 2, is not available anymore. Hence, switch scripts to use Python 3 explicitly.

Hi!
From: Andy Shevchenko andriy.shevchenko@linux.intel.com
commit 51839e29cb5954470ea4db7236ef8c3d77a6e0bb upstream.
Some distributions are about to switch to Python 3 support only. This means that /usr/bin/python, which is Python 2, is not available anymore. Hence, switch scripts to use Python 3 explicitly.
I'd say this is unsuitable for -stable.
Old distributions may not have python3 installed, and we should not change this dependency in the middle of the series.
Python is not listed in Documentation/Changes . Perhaps it should be?
Best regards, Pavel

What distro that was released in 2017 (the year 4.14.0 was released) did not have python3 on it?

It's not required to build/boot, just these helper scripts.

In anything yocto-based, for example, you explicitely select which packages you want. And changing dependencies in middle of stable release is surprising and against our documentation.

Yocto documentation does not dictate kernel development processes.
good luck!

How is this all relevant?
Scripts where the interpreter changed are not supposed to be used outside of the (kernel) development process. No user should really rely on those scripts to produce anything at any point of time or even be there.
