[ Upstream commit 7dd5d2514a8ea58f12096e888b0bd050d7eae20a ]
If SER L2 occurs during the WoWLAN resume flow, the add interface flow is triggered by ieee80211_reconfig(). However, due to rtw89_wow_resume() return failure, it will cause the add interface flow to be executed again, resulting in a double add list and causing a kernel panic. Therefore, we have added a check to prevent double adding of the list.

[ Upstream commit 94745807f3ebd379f23865e6dab196f220664179 ]
Syzbot points out that skb_trim() has a sanity check on the existing length of the skb, which can be uninitialised in some error paths. The intent here is clearly just to reset the length to zero before resubmitting, so switch to calling __skb_set_length(skb, 0) directly. In addition, __skb_set_length() already contains a call to skb_reset_tail_pointer(), so remove the redundant call.
The syzbot report came from ath9k_hif_usb_reg_in_cb(), but there's a similar usage of skb_trim() in ath9k_hif_usb_rx_cb(), change both while we're at it.

[ Upstream commit 3363c460ef726ba693704dbcd73b7e7214ccc788 ]
The macros FOUR_ROUNDS_AND_SCHED and DO_4ROUNDS rely on an unexpected/undocumented behavior of the GNU assembler, which might change in the future (https://sourceware.org/bugzilla/show_bug.cgi?id=32073).
M (1) (2) // 1 arg !? Future: 2 args M 1 + 2 // 1 arg !? Future: 3 args
M 1 2 // 2 args
Add parentheses around the single arguments to support future GNU assembler and LLVM integrated assembler (when the IsOperator hack from the following link is dropped).

Use the generic crypto_authenc_extractkeys helper instead of custom parsing code that is slightly broken. Also fix a number of memory leaks by moving memory allocation from setkey to init_tfm (setkey can be called multiple times over the life of a tfm).
Finally accept all hash key lengths by running the digest over extra-long keys.

[ Upstream commit 7ccb750dcac8abbfc7743aab0db6a72c1c3703c7 ]
Use the generic crypto_authenc_extractkeys helper instead of custom parsing code that is slightly broken. Also fix a number of memory leaks by moving memory allocation from setkey to init_tfm (setkey can be called multiple times over the life of a tfm).
Finally accept all hash key lengths by running the digest over extra-long keys.

In ice_sched_add_root_node() and ice_sched_add_node() there are calls to devm_kcalloc() in order to allocate memory for array of pointers to 'ice_sched_node' structure. But incorrect types are used as sizeof() arguments in these calls (structures instead of pointers) which leads to over allocation of memory.
Adjust over allocation of memory by correcting types in devm_kcalloc() sizeof() arguments.

[ Upstream commit 87c1c28a9aa149489e1667f5754fc24f4973d2d0 ]
When the upper layer requests to cancel an ongoing scan, a race is possible in which by the time the driver starts to handle the upper layers scan cancel flow, the FW already completed handling the scan request and the driver received the scan complete notification but still did not handle the notification. In such a case the FW will simply ignore the scan abort request coming from the driver, no notification would arrive from the FW and the entire abort flow would be considered a failure.
To better handle this, check the status code returned by the FW for the scan abort command. In case the status indicates that no scan was aborted, complete the scan abort flow with success, i.e., the scan was aborted, as the flow is expected to consume the scan complete notification.

This shouldn't happen at all, since in station mode all MMPDUs go through the TXQ for the STA, and not this function. There may or may not be a race in mac80211 through which this might happen for some frames while a station is being added, but in that case we can also just drop the frame and pretend the STA didn't exist yet.
Also, the code is simply wrong since it uses deflink, and it's not easy to fix it since the mvmvif->ap_sta pointer cannot be used without the mutex, and perhaps the right link might not even be known.
Just drop the frame at that point instead of trying to fix it up.

During the list_for_each_entry_rcu iteration call of xenvif_flush_hash, kfree_rcu does not exist inside the rcu read critical section, so if kfree_rcu is called when the rcu grace period ends during the iteration, UAF occurs when accessing head->next after the entry becomes free.
Therefore, to solve this, you need to change it to list_for_each_entry_safe.

Previously, some sanity check have been done in dump_mapping() before the print facility parsing '%pd' though, it's still possible to run into an invalid dentry.d_name.name.
Since dump_mapping() only needs to dump the filename only, retrieve it by itself in a safer way to prevent an unnecessary crash.
Note that either retrieving the filename with '%pd' or strncpy_from_kernel_nofault(), the filename could be unreliable.

[ Upstream commit 0a6ad4d9e1690c7faa3a53f762c877e477093657 ]
Occasionally when the system goes into pm_suspend, the suspend might fail due to a PHY access error on the network adapter. Previously, this would have caused the whole system to fail to go to a low power state. An example of this was reported in the following Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=205015
[ 1663.694828] e1000e 0000:00:19.0 eth0: Failed to disable ULP [ 1664.731040] asix 2-3:1.0 eth1: link up, 100Mbps, full-duplex, lpa 0xC1E1 [ 1665.093513] e1000e 0000:00:19.0 eth0: Hardware Error [ 1665.596760] e1000e 0000:00:19.0: pci_pm_resume+0x0/0x80 returned 0 after 2975399 usecs
and then the system never recovers from it, and all the following suspend failed due to this [22909.393854] PM: pci_pm_suspend(): e1000e_pm_suspend+0x0/0x760 [e1000e] returns -2 [22909.393858] PM: dpm_run_callback(): pci_pm_suspend+0x0/0x160 returns -2 [22909.393861] PM: Device 0000:00:1f.6 failed to suspend async: error -2
This can be avoided by changing the return values of __e1000_shutdown and e1000e_pm_suspend functions so that they always return 0 (success). This is consistent with what other drivers do.
If the e1000e driver encounters a hardware error during suspend, potential side effects include slightly higher power draw or non-working wake on LAN. This is preferred to a system-level suspend failure, and a warning message is written to the system log, so that the user can be aware that the LAN controller experienced a problem during suspend.

Like other Asus Vivobooks, the Asus Vivobook Go E1404GAB has a DSDT that describes IRQ 1 as ActiveLow, while the kernel overrides to Edge_High.
This override prevents the internal keyboard from working.
Fix the problem by adding this laptop to the table that prevents the kernel from overriding the IRQ.

acpi_video_get_backlight_type() will pick the non working native backlight by default, add a quirk to select the working vendor backlight instead.

Some Asus AMD systems are reported to not be able to change EPP values because the BIOS doesn't advertise support for the CPPC MSR and the PCC region is not configured.
However the ACPI 6.2 specification allows CPC registers to be declared in FFH: ``` Starting with ACPI Specification 6.2, all _CPC registers can be in PCC, System Memory, System IO, or Functional Fixed Hardware address spaces. OSPM support for this more flexible register space scheme is indicated by the “Flexible Address Space for CPPC Registers” _OSC bit. ```
If this _OSC has been set allow using FFH to configure EPP.

Actual impact of this issue was not identified but I propose to fix the undefined behaviour. The proposed fix to prevent those out of bound shifts consist of precalculating exponent before using it the shift operations by taking min value from the actual exponent and maximum possible number of bits.

Another device has been reported to be unreliable if we have more than one outstanding command. In this new case, data corruption may occur. Since we have two devices now needing this quirky behavior, make a generic quirk flag.
The same Apple quirk is clearly not "temporary", so update the comment while moving it.

However, the ath12k_dp_rx_process() function access ath12k_soc_dp_stats::hal_reo_error using the REO destination SRNG ring ID, which is incorrect. SRNG ring ID differ from normal ring ID, and this usage leads to out-of-bounds array access.

[ Upstream commit dc171114926ec390ab90f46534545420ec03e458 ]
It is not particularly useful to release locks (the EC mutex and the ACPI global lock, if present) and re-acquire them immediately thereafter during EC address space accesses in acpi_ec_space_handler().
First, releasing them for a while before grabbing them again does not really help anyone because there may not be enough time for another thread to acquire them.
Second, if another thread successfully acquires them and carries out a new EC write or read in the middle if an operation region access in progress, it may confuse the EC firmware, especially after the burst mode has been enabled.
Finally, manipulating the locks after writing or reading every single byte of data is overhead that it is better to avoid.
Accordingly, modify the code to carry out EC address space accesses entirely without releasing the locks.

Even then, if we issue ioctl(SIOCSIFADDR) for a new IPv4 address, devinet_ioctl() allocates struct in_ifaddr and fails later in inet_set_ifa() because in_dev is NULL.
Let's move the check earlier.

Coverity reported that u8 rx_mask << 24 will become signed 32 bits, which casting to unsigned 64 bits will do sign extension. For example, putting 0x80000000 (signed 32 bits) to a u64 variable will become 0xFFFFFFFF_80000000.
The real case we meet is: rx_mask[0...3] = ff ff 00 00 ra_mask = 0xffffffff_ff0ff000
After this fix: rx_mask[0...3] = ff ff 00 00 ra_mask = 0x00000000_ff0ff000
Fortunately driver does bitwise-AND with incorrect ra_mask and supported rates (1ss and 2ss rate only) afterward, so the final rate mask of original code is still correct.

The NETLINK_FIB_LOOKUP netlink family can be used to perform a FIB lookup according to user provided parameters and communicate the result back to user space.
However, unlike other users of the FIB lookup API, the upper DSCP bits and the ECN bits of the DS field are not masked, which can result in the wrong result being returned.
Solve this by masking the upper DSCP bits and the ECN bits using IPTOS_RT_MASK.
The structure that communicates the request and the response is not exported to user space, so it is unlikely that this netlink family is actually in use [1].

TP8018 introduced a new TLS PSK identifier version (version 1), which appended a PSK hash value to the existing identifier (cf NVMe TCP specification v1.1, section 3.6.1.3 'TLS PSK and PSK Identity Derivation'). An original (version 0) identifier has the form:
NVMe0<type><hmac> <hostnqn> <subsysnqn>
and a version 1 identifier has the form:
NVMe1<type><hmac> <hostnqn> <subsysnqn> <hash>
This patch modifies the lookup algorthm to compare only the first part of the identifier (excluding the hash value) to handle both version 0 and version 1 identifiers. And the spec declares 'version 0' identifiers obsolete, so the lookup algorithm is modified to prever v1 identifiers.

There is a difference between TLS configured (ie the user has provisioned/requested a key) and TLS enabled (ie the connection is encrypted with TLS). This becomes important for secure concatenation, where the initial authentication is run on an unencrypted connection (ie with TLS configured, but not enabled), and then the queue is reset to run over TLS (ie TLS configured _and_ enabled). So to differentiate between those two states store the generated key in opts->tls_key (as we're using the same TLS key for all queues), the key serial of the resulting TLS handshake in ctrl->tls_pskid (to signal that TLS on the admin queue is enabled), and a simple flag for the queues to indicated that TLS has been enabled.

W=1 builds with GCC 14.2.0 warn that:
.../aq_ethtool.c:278:59: warning: ‘%d’ directive output may be truncated writing between 1 and 11 bytes into a region of size 6 [-Wformat-truncation=] 278 | snprintf(tc_string, 8, "TC%d ", tc); | ^~ .../aq_ethtool.c:278:56: note: directive argument in the range [-2147483641, 254] 278 | snprintf(tc_string, 8, "TC%d ", tc); | ^~~~~~~ .../aq_ethtool.c:278:33: note: ‘snprintf’ output between 5 and 15 bytes into a destination of size 8 278 | snprintf(tc_string, 8, "TC%d ", tc); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
tc is always in the range 0 - cfg->tcs. And as cfg->tcs is a u8, the range is 0 - 255. Further, on inspecting the code, it seems that cfg->tcs will never be more than AQ_CFG_TCS_MAX (8), so the range is actually 0 - 8.
So, it seems that the condition that GCC flags will not occur. But, nonetheless, it would be nice if it didn't emit the warning.
It seems that this can be achieved by changing the format specifier from %d to %u, in which case I believe GCC recognises an upper bound on the range of tc of 0 - 255. After some experimentation I think this is due to the combination of the use of %u and the type of cfg->tcs (u8).
Empirically, updating the type of the tc variable to unsigned int has the same effect.
As both of these changes seem to make sense in relation to what the code is actually doing - iterating over unsigned values - do both.
Compile tested only.

Algorithm registration is usually carried out during module init, where as little work as possible should be carried out. The SIMD code violated this rule by allocating a tfm, this then triggers a full test of the algorithm which may dead-lock in certain cases.
SIMD is only allocating the tfm to get at the alg object, which is in fact already available as it is what we are registering. Use that directly and remove the crypto_alloc_tfm call.
Also remove some obsolete and unused SIMD API.

[ Upstream commit ae5a0456e0b4cfd7e61619e55251ffdf1bc7adfb ]
Modify netpoll_setup() and __netpoll_setup() to ensure that the netpoll structure (np) is left in a clean state if setup fails for any reason. This prevents carrying over misconfigured fields in case of partial setup success.
Key changes: - np->dev is now set only after successful setup, ensuring it's always NULL if netpoll is not configured or if netpoll_setup() fails. - np->local_ip is zeroed if netpoll setup doesn't complete successfully. - Added DEBUG_NET_WARN_ON_ONCE() checks to catch unexpected states. - Reordered some operations in __netpoll_setup() for better logical flow.
These changes improve the reliability of netpoll configuration, since it assures that the structure is fully initialized or totally unset.

[ Upstream commit 0d9e5df4a257afc3a471a82961ace9a22b88295a ]
We found that one close-wait socket was reset by the other side due to a new connection reusing the same port which is beyond our expectation, so we have to investigate the underlying reason.
The following experiment is conducted in the test environment. We limit the port range from 40000 to 40010 and delay the time to close() after receiving a fin from the active close side, which can help us easily reproduce like what happened in production.
Here are three connections captured by tcpdump: 127.0.0.1.40002 > 127.0.0.1.9999: Flags [S], seq 2965525191 127.0.0.1.9999 > 127.0.0.1.40002: Flags [S.], seq 2769915070 127.0.0.1.40002 > 127.0.0.1.9999: Flags [.], ack 1 127.0.0.1.40002 > 127.0.0.1.9999: Flags [F.], seq 1, ack 1 // a few seconds later, within 60 seconds 127.0.0.1.40002 > 127.0.0.1.9999: Flags [S], seq 2965590730 127.0.0.1.9999 > 127.0.0.1.40002: Flags [.], ack 2 127.0.0.1.40002 > 127.0.0.1.9999: Flags [R], seq 2965525193 // later, very quickly 127.0.0.1.40002 > 127.0.0.1.9999: Flags [S], seq 2965590730 127.0.0.1.9999 > 127.0.0.1.40002: Flags [S.], seq 3120990805 127.0.0.1.40002 > 127.0.0.1.9999: Flags [.], ack 1
As we can see, the first flow is reset because: 1) client starts a new connection, I mean, the second one 2) client tries to find a suitable port which is a timewait socket (its state is timewait, substate is fin_wait2) 3) client occupies that timewait port to send a SYN 4) server finds a corresponding close-wait socket in ehash table, then replies with a challenge ack 5) client sends an RST to terminate this old close-wait socket.
I don't think the port selection algo can choose a FIN_WAIT2 socket when we turn on tcp_tw_reuse because on the server side there remain unread data. In some cases, if one side haven't call close() yet, we should not consider it as expendable and treat it at will.
Even though, sometimes, the server isn't able to call close() as soon as possible like what we expect, it can not be terminated easily, especially due to a second unrelated connection happening.
After this patch, we can see the expected failure if we start a connection when all the ports are occupied in fin_wait2 state: "Ncat: Cannot assign requested address."

In the cases changed here, key iteration isn't done from an RCU critical section, but rather using the wiphy lock as protection. Therefore, just use ieee80211_iter_keys(). The link switch case can therefore also use sync commands.

iwl_mvm_tx_skb_sta() and iwl_mvm_tx_mpdu() verify that the mvmvsta pointer is not NULL. It retrieves this pointer using iwl_mvm_sta_from_mac80211, which is dereferencing the ieee80211_sta pointer. If sta is NULL, iwl_mvm_sta_from_mac80211 will dereference a NULL pointer. Fix this by checking the sta pointer before retrieving the mvmsta from it. If sta is not NULL, then mvmsta isn't either.

This adds a Kconfig option and boot param to allow removing the FOLL_FORCE flag from /proc/pid/mem write calls because it can be abused.
The traditional forcing behavior is kept as default because it can break GDB and some other use cases.
Previously we tried a more sophisticated approach allowing distributions to fine-tune /proc/pid/mem behavior, however that got NAK-ed by Linus [1], who prefers this simpler approach with semantics also easier to understand for users.

Use perf_allow_kernel() for 'pa_enable' (physical addresses), 'pct_enable' (physical timestamps) and context IDs. This means that perf_event_paranoid is now taken into account and LSM hooks can be used, which is more consistent with other perf_event_open calls. For example PERF_SAMPLE_PHYS_ADDR uses perf_allow_kernel() rather than just perfmon_capable().
This also indirectly fixes the following error message which is misleading because perf_event_paranoid is not taken into account by perfmon_capable():
$ perf record -e arm_spe/pa_enable/

[ Upstream commit 2423cc20087ae9a7b7af575aa62304ef67cad7b6 ]
This patch moves the evaluation of data[IFLA_CAN_CTRLMODE] in function can_changelink in front of the evaluation of data[IFLA_CAN_BITTIMING].
This avoids a call to do_set_data_bittiming providing a stale can_priv::ctrlmode with a CAN_CTRLMODE_FD flag not matching the requested state when switching between a CAN Classic and CAN-FD bitrate.
In the same manner the evaluation of data[IFLA_CAN_CTRLMODE] in function can_validate is also moved in front of the evaluation of data[IFLA_CAN_BITTIMING].
This is a preparation for patches where the nominal and data bittiming may have interdependencies on the driver side depending on the CAN_CTRLMODE_FD flag state.

[ Upstream commit 7eced90b202d63cdc1b9b11b1353adb1389830f9 ]
The reasons for PTEs in the kernel direct map to be marked invalid are not limited to kfence / debug pagealloc machinery. In particular, memfd_secret() also steals pages with set_direct_map_invalid_noflush().
When building the transitional page tables for kexec from the current kernel's page tables, those pages need to become regular writable pages, otherwise, if the relocation places kexec segments over such pages, a fault will occur during kexec, leading to host going dark during kexec.
This patch addresses the kexec issue by marking any PTE as valid if it is not none. While this fixes the kexec crash, it does not address the security concern that if processes owning secret memory are not terminated before kexec, the secret content will be mapped in the new kernel without being scrubbed.

[ Upstream commit 569bf6d481b0b823c3c9c3b8be77908fd7caf66b ]
When reading registers from the PHY using the SIOCGMIIREG IOCTL any errors returned from either mdiobus_read() or mdiobus_c45_read() are ignored, and parts of the returned error is passed as the register value back to user-space.
For example, if mdiobus_c45_read() is used with a bus that do not implement the read_c45() callback -EOPNOTSUPP is returned. This is however directly stored in mii_data->val_out and returned as the registers content. As val_out is a u16 the error code is truncated and returned as a plausible register value.
Fix this by first checking the return value for errors before returning it as the register content.

When the SRSO mitigation is disabled, either via mitigations=off or spec_rstack_overflow=off, the warning about the lack of IBPB-enhancing microcode is printed anyway.
This is unnecessary since the user has turned off the mitigation.
[ bp: Massage, drop SBPB rationale as it doesn't matter because when mitigations are disabled x86_pred_cmd is not being used anyway. ]

[ Upstream commit 08062af0a52107a243f7608fd972edb54ca5b7f8 ]
In commit 6f8b12d661d0 ("net: napi: add hard irqs deferral feature") napi_defer_irqs was added to net_device and napi_defer_irqs_count was added to napi_struct, both as type int.
This value never goes below zero, so there is not reason for it to be a signed int. Change the type for both from int to u32, and add an overflow check to sysfs to limit the value to S32_MAX.
The limit of S32_MAX was chosen because the practical limit before this patch was S32_MAX (anything larger was an overflow) and thus there are no behavioral changes introduced. If the extra bit is needed in the future, the limit can be raised.
Before this patch:
$ sudo bash -c 'echo 2147483649 > /sys/class/net/eth4/napi_defer_hard_irqs' $ cat /sys/class/net/eth4/napi_defer_hard_irqs -2147483647
After this patch:
$ sudo bash -c 'echo 2147483649 > /sys/class/net/eth4/napi_defer_hard_irqs' bash: line 0: echo: write error: Numerical result out of range
Similarly, /sys/class/net/XXXXX/tx_queue_len is defined as unsigned:
include/linux/netdevice.h: unsigned int tx_queue_len;
And has an overflow check:
dev_change_tx_queue_len(..., unsigned long new_len):
if (new_len != (unsigned int)new_len) return -ERANGE;

Before the device is enabled again, the device may still store the previously processed data. If an error occurs in the previous task, the device may fail to be enabled again. Therefore, before enabling device, reset the device to restore the initial state.

[ Upstream commit 54001d0f2fdbc7852136a00f3e6fc395a9547ae5 ]
When asynchronous encryption is used KTLS sends out the final data at proto->close time. This becomes problematic when the task calling close() receives a signal. In this case it can happen that tcp_sendmsg_locked() called at close time returns -ERESTARTSYS and the final data is not sent.
The described situation happens when KTLS is used in conjunction with io_uring, as io_uring uses task_work_add() to add work to the current userspace task. A discussion of the problem along with a reproducer can be found in [1] and [2]
Fix this by waiting for the asynchronous encryption to be completed on the final message. With this there is no data left to be sent at close time.

[ Upstream commit 8f246b7c0a1be0882374f2ff831a61f0dbe77678 ]
Kafs wants to be able to cache the contents of directories (and symlinks), but whilst these are downloaded from the server with the FS.FetchData RPC op and similar, the same as for regular files, they can't be updated by FS.StoreData, but rather have special operations (FS.MakeDir, etc.).
Now, rather than redownloading a directory's content after each change made to that directory, kafs modifies the local blob. This blob can be saved out to the cache, and since it's using netfslib, kafs just marks the folios dirty and lets ->writepages() on the directory take care of it, as for an regular file.
This is fine as long as there's a cache as although the upload stream is disabled, there's a cache stream to drive the procedure. But if the cache goes away in the meantime, suddenly there's no way do any writes and the code gets confused, complains "R=%x: No submit" to dmesg and leaves the dirty folio hanging.
Fix this by just cancelling the store of the folio if neither stream is active. (If there's no cache at the time of dirtying, we should just not mark the folio dirty).

For an invalid input value that is out of the given range, currently USB-audio driver corrects the value silently and accepts without errors. This is no wrong behavior, per se, but the recent kselftest rather wants to have an error in such a case, hence a different behavior is expected now.
This patch adds a sanity check at each control put for the standard mixer types and returns an error if an invalid value is given.
Note that this covers only the standard mixer types. The mixer quirks that have own control callbacks would need different coverage.

Breno observed panics when using failslab under certain conditions during runtime:
can not alloc irq_pin_list (-1,0,20) Kernel panic - not syncing: IO-APIC: failed to add irq-pin. Can not proceed
panic+0x4e9/0x590 mp_irqdomain_alloc+0x9ab/0xa80 irq_domain_alloc_irqs_locked+0x25d/0x8d0 __irq_domain_alloc_irqs+0x80/0x110 mp_map_pin_to_irq+0x645/0x890 acpi_register_gsi_ioapic+0xe6/0x150 hpet_open+0x313/0x480
That's a pointless panic which is a leftover of the historic IO/APIC code which panic'ed during early boot when the interrupt allocation failed.
The only place which might justify panic is the PIT/HPET timer_check() code which tries to figure out whether the timer interrupt is delivered through the IO/APIC. But that code does not require to handle interrupt allocation failures. If the interrupt cannot be allocated then timer delivery fails and it either panics due to that or falls back to legacy mode.
Cure this by removing the panic wrapper around __add_pin_to_irq_node() and making mp_irqdomain_alloc() aware of the failure condition and handle it as any other failure in this function gracefully.

[ Upstream commit 838ba7733e4e3a94a928e8d0a058de1811a58621 ]
Logical destination mode of the local APIC is used for systems with up to 8 CPUs. It has an advantage over physical destination mode as it allows to target multiple CPUs at once with IPIs.
That advantage was definitely worth it when systems with up to 8 CPUs were state of the art for servers and workstations, but that's history.
Aside of that there are systems which fail to work with logical destination mode as the ACPI/DMI quirks show and there are AMD Zen1 systems out there which fail when interrupt remapping is enabled as reported by Rob and Christian. The latter problem can be cured by firmware updates, but not all OEMs distribute the required changes.
Physical destination mode is guaranteed to work because it is the only way to get a CPU up and running via the INIT/INIT/STARTUP sequence.
As the number of CPUs keeps increasing, logical destination mode becomes a less used code path so there is no real good reason to keep it around.
Therefore remove logical destination mode support for 64-bit and default to physical destination mode.

[ Upstream commit 6aa8700150f7dc62f60b4cf5b1624e2e3d9ed78e ]
Registering Numark Party Mix II fails with error 'bogus bTerminalLink 1'. The problem stems from the driver not being able to find input/output terminals required to configure audio streaming. The information about those terminals is stored in AudioControl Interface. Numark device contains 2 AudioControl Interfaces and the driver checks only one of them.
According to the USB standard, a device can have multiple audio functions, each represented by Audio Interface Collection. Every audio function is considered to be closed box and will contain unique AudioControl Interface and zero or more AudioStreaming and MIDIStreaming Interfaces.
The Numark device adheres to the standard and defines two audio functions: - MIDIStreaming function - AudioStreaming function It starts with MIDI function, followed by the audio function. The driver saves the first AudioControl Interface in `snd_usb_audio` structure associated with the entire device. It then attempts to use this interface to query for terminals and clocks. However, this fails because the correct information is stored in the second AudioControl Interface, defined in the second Audio Interface Collection.
This patch introduces a structure holding association between each MIDI/Audio Interface and its corresponding AudioControl Interface, instead of relying on AudioControl Interface defined for the entire device. This structure is populated during usb probing phase and leveraged later when querying for terminals and when sending USB requests.
Alternative solutions considered include: - defining a quirk for Numark where the order of interface is manually changed, or terminals are hardcoded in the driver. This solution would have fixed only this model, though it seems that device is USB compliant, and it also seems that other devices from this company may be affected. What's more, it looks like products from other manufacturers have similar problems, i.e. Rane One DJ console - keeping a list of all AudioControl Interfaces and querying all of them to find required information. That would have solved my problem and have low probability of breaking other devices, as we would always start with the same logic of querying first AudioControl Interface. This solution would not have followed the standard though.
This patch preserves the `snd_usb_audio.ctrl_intf` variable, which holds the first AudioControl Interface, and uses it as a fallback when some interfaces are not parsed correctly and lack an associated AudioControl Interface, i.e., when configured via quirks.

There should be no functional changes.

[ Upstream commit c032044e9672408c534d64a6df2b1ba14449e948 ]
Add trivial support for audio streaming on the RME Digiface USB. Binds only to the first interface to allow userspace to directly drive the complex I/O and matrix mixer controls.

[ Upstream commit 611a96f6acf2e74fe28cb90908a9c183862348ce ]
Implement sync, output format, and input status mixer controls, to allow the interface to be used as a straight ADAT/SPDIF (+ Headphones) I/O interface.
This does not implement the matrix mixer, output gain controls, or input level meter feedback. The full mixer interface is only really usable using a dedicated userspace control app (there are too many mixer nodes for alsamixer to be usable), so for now we leave it up to userspace to directly control these features using raw USB control messages. This is similar to how it's done with some FireWire interfaces (ffado-mixer).

If reading version and variant from registers fails (which is unlikely but possible, because it is a read over bus), the driver will proceed and perform device configuration based on uninitialized stack variables. Handle it a bit better - bail out without doing any init and failing the update status Soundwire callback.

The code path for kcontrol accesses have often nested locks of both card's controls_rwsem and power_ref, and applies in that order. However, what could take much longer is the latter, power_ref; it waits for the power state of the device, and it pretty much depends on the user's action.
This patch swaps the locking order of those locks to a more natural way, namely, power_ref -> controls_rwsem, in order to shorten the time of possible nested locks. For consistency, power_ref is taken always in the top-level caller side (that is, *_user() functions and the ioctl handler itself).

Protect against the kcpuid code parsing faulty max subleaf numbers through a min() expression. Thus, ensuring that max_subleaf will always be ≤ MAX_SUBLEAF_NUM.
Use "u32" for the subleaf numbers since kcpuid is compiled with -Wextra, which includes signed/unsigned comparisons warnings.

[ Upstream commit 24cf2bc982ffe02aeffb4a3885c71751a2c7023b ]
Assume there's a multithreaded application that runs untrusted user code. Each thread has its stack/code protected by a non-zero PKEY, and the PKRU register is set up such that only that particular non-zero PKEY is enabled. Each thread also sets up an alternate signal stack to handle signals, which is protected by PKEY zero. The PKEYs man page documents that the PKRU will be reset to init_pkru when the signal handler is invoked, which means that PKEY zero access will be enabled. But this reset happens after the kernel attempts to push fpu state to the alternate stack, which is not (yet) accessible by the kernel, which leads to a new SIGSEGV being sent to the application, terminating it.
Enabling both the non-zero PKEY (for the thread) and PKEY zero in userspace will not work for this use case. It cannot have the alt stack writeable by all - the rationale here is that the code running in that thread (using a non-zero PKEY) is untrusted and should not have access to the alternate signal stack (that uses PKEY zero), to prevent the return address of a function from being changed. The expectation is that kernel should be able to set up the alternate signal stack and deliver the signal to the application even if PKEY zero is explicitly disabled by the application. The signal handler accessibility should not be dictated by whatever PKRU value the thread sets up.
The PKRU register is managed by XSAVE, which means the sigframe contents must match the register contents - which is not the case here. It's required that the signal frame contains the user-defined PKRU value (so that it is restored correctly from sigcontext) but the actual register must be reset to init_pkru so that the alt stack is accessible and the signal can be delivered to the application. It seems that the proper fix here would be to remove PKRU from the XSAVE framework and manage it separately, which is quite complicated. As a workaround, do this:
orig_pkru = rdpkru(); wrpkru(orig_pkru & init_pkru_value); xsave_to_user_sigframe(); put_user(pkru_sigframe_addr, orig_pkru)
In preparation for writing PKRU to sigframe, pass PKRU as an additional parameter down the call chain from get_sigframe().
No functional change.

A process can disable access to the alternate signal stack by not enabling the altstack's PKEY in the PKRU register.
Nevertheless, the kernel updates the PKRU temporarily for signal handling. However, in sigreturn(), restore_sigcontext() will restore the PKRU to the user-defined PKRU value.
This will cause restore_altstack() to fail with a SIGSEGV as it needs read access to the altstack which is prohibited by the user-defined PKRU value.
Fix this by restoring altstack before restoring PKRU.

A kexec kernel boot failure is sometimes observed on AMD CPUs due to an unmapped EFI config table array. This can be seen when "nogbpages" is on the kernel command line, and has been observed as a full BIOS reboot rather than a successful kexec.
This was also the cause of reported regressions attributed to Commit 7143c5f4cf20 ("x86/mm/ident_map: Use gbpages only where full GB page should be mapped.") which was subsequently reverted.
To avoid this page fault, explicitly include the EFI config table array in the kexec identity map.
Further explanation:
The following 2 commits caused the EFI config table array to be accessed when enabling sev at kernel startup.
commit ec1c66af3a30 ("x86/compressed/64: Detect/setup SEV/SME features earlier during boot") commit c01fce9cef84 ("x86/compressed: Add SEV-SNP feature detection/setup")
This is in the code that examines whether SEV should be enabled or not, so it can even affect systems that are not SEV capable.
This may result in a page fault if the EFI config table array's address is unmapped. Since the page fault occurs before the new kernel establishes its own identity map and page fault routines, it is unrecoverable and kexec fails.
Most often, this problem is not seen because the EFI config table array gets included in the map by the luck of being placed at a memory address close enough to other memory areas that *are* included in the map created by kexec.
Both the "nogbpages" command line option and the "use gpbages only where full GB page should be mapped" change greatly reduce the chance of being included in the map by luck, which is why the problem appears.

[ Upstream commit cc31744a294584a36bf764a0ffa3255a8e69f036 ]
When ident_pud_init() uses only GB pages to create identity maps, large ranges of addresses not actually requested can be included in the resulting table; a 4K request will map a full GB. This can include a lot of extra address space past that requested, including areas marked reserved by the BIOS. That allows processor speculation into reserved regions, that on UV systems can cause system halts.
Only use GB pages when map creation requests include the full GB page of space. Fall back to using smaller 2M pages when only portions of a GB page are included in the request.
No attempt is made to coalesce mapping requests. If a request requires a map entry at the 2M (pmd) level, subsequent mapping requests within the same 1G region will also be at the pmd level, even if adjacent or overlapping such requests could have been combined to map a full GB page. Existing usage starts with larger regions and then adds smaller regions, so this should not have any great consequence.

Clang on higher optimization levels detects that NULL is passed to printf("%s") and warns about it. While printf() from nolibc gracefully handles that NULL, it is undefined behavior as per POSIX, so the warning is reasonable. Avoid the warning by transforming NULL into a non-NULL placeholder.

[ Upstream commit fd69dfe6789f4ed46d1fdb52e223cff83946d997 ]
I have been wondering why DPCM needs special flag (= dpcm_playback/capture) to use it. Below is the history why it was added to ASoC.
(A) In beginning, there was no dpcm_xxx flag on ASoC. It checks channels_min for DPCM, same as current non-DPCM. Let's name it as "validation check" here.
if (rtd->dai_link->dynamic || rtd->dai_link->no_pcm) { if (cpu_dai->driver->playback.channels_min) playback = 1; if (cpu_dai->driver->capture.channels_min) capture = 1;
(B) commit 1e9de42f4324 ("ASoC: dpcm: Explicitly set BE DAI link supported stream directions") force to use dpcm_xxx flag on DPCM. According to this commit log, this is because "Some BE dummy DAI doesn't set channels_min for playback/capture". But we don't know which DAI is it, and not know why it can't/don't have channels_min. Let's name it as "no_chan_DAI" here. According to the code and git-log, it is used as DCPM-BE and is CPU DAI. I think the correct solution was set channels_min on "no_chan_DAI" side, not update ASoC framework side. But everything is under smoke today.
if (rtd->dai_link->dynamic || rtd->dai_link->no_pcm) { playback = rtd->dai_link->dpcm_playback; capture = rtd->dai_link->dpcm_capture;
(C) commit 9b5db059366a ("ASoC: soc-pcm: dpcm: Only allow playback/capture if supported") checks channels_min (= validation check) again. Because DPCM availability was handled by dpcm_xxx flag at that time, but some Sound Card set it even though it wasn't available. Clearly there's a contradiction here. I think correct solution was update Sound Card side instead of ASoC framework. Sound Card side will be updated to handle this issue later (commit 25612477d20b ("ASoC: soc-dai: set dai_link dpcm_ flags with a helper"))
if (rtd->dai_link->dynamic || rtd->dai_link->no_pcm) { ... playback = rtd->dai_link->dpcm_playback && snd_soc_dai_stream_valid(cpu_dai, ...); capture = rtd->dai_link->dpcm_capture && snd_soc_dai_stream_valid(cpu_dai, ...);
This (C) patch should have broken "no_chan_DAI" which doesn't have channels_min, but there was no such report during this 4 years. Possibilities case are as follows - No one is using "no_chan_DAI" - "no_chan_DAI" is no longer exist : was removed ? - "no_chan_DAI" is no longer exist : has channels_min ?
Because of these history, this dpcm_xxx is unneeded flag today. But because we have been used it for 10 years since (B), it may have been used differently. For example some DAI available both playback/capture, but it set dpcm_playback flag only, in this case dpcm_xxx flag is used as availability limitation. We can use playback_only flag instead in this case, but it is very difficult to find such DAI today.
Let's add grace time to remove dpcm_playback/capture flag.
This patch don't use dpcm_xxx flag anymore, and indicates warning to use xxx_only flag if both playback/capture were available but using only one of dpcm_xxx flag, and not using xxx_only flag.

As already done for x86_64 and compat mode, do not use memcpy() to extract syscall arguments from struct pt_regs but rather just perform direct assignments. Binary output differences are negligible, and actually ends up using less stack space:

For kernels built with CONFIG_FORCE_NR_CPUS=y, the nr_cpu_ids is defined as NR_CPUS instead of the number of possible cpus, this will cause the following system panic:

Considering that there may be holes in the CPU numbers, use the maximum possible cpu number, instead of nr_cpu_ids, for configuring enqueue and dequeue limits.

Also avoid a UAF race during unregistering where the sysctl attributes were usable after the info struct was freed.

[ Upstream commit 4a6921095eb04a900e0000da83d9475eb958e61e ]
In the pxafb_probe function, it calls the pxafb_init_fbinfo function, after which &fbi->task is associated with pxafb_task. Moreover, within this pxafb_init_fbinfo function, the pxafb_blank function within the &pxafb_ops struct is capable of scheduling work.
If we remove the module which will call pxafb_remove to make cleanup, it will call unregister_framebuffer function which can call do_unregister_framebuffer to free fbi->fb through put_fb_info(fb_info), while the work mentioned above will be used. The sequence of operations that may lead to a UAF bug is as follows:
CPU0 CPU1
| pxafb_task pxafb_remove | unregister_framebuffer(info) | do_unregister_framebuffer(fb_info) | put_fb_info(fb_info) | // free fbi->fb | set_ctrlr_state(fbi, state) | __pxafb_lcd_power(fbi, 0) | fbi->lcd_power(on, &fbi->fb.var) | //use fbi->fb

There is no need to hold the genpd-lock, while assigning the dev->pm_domain. In fact, it becomes a problem on a PREEMPT_RT based configuration as the genpd-lock may be a raw spinlock, while the lock acquired through the call to dev_pm_domain_set() is a regular spinlock.
To fix the problem, let's simply move the calls to dev_pm_domain_set() outside the genpd-lock.

The coredump code does not log the process ID and the comm consistently, logs unescaped comm when it does log it, and does not always use the ratelimited logging. That makes it harder to analyze logs and puts the system at the risk of spamming the system log incase something crashes many times over and over again.
Fix that by logging TGID and comm (escaped) consistently and using the ratelimited logging always.

Currently, if the rcuscale module's async module parameter is specified for RCU implementations that do not have async primitives such as RCU Tasks Rude (which now lacks a call_rcu_tasks_rude() function), there will be a series of splats due to calls to a NULL pointer. This commit therefore warns of this situation, but switches to non-async testing.

and here:

It is likely that FW reserves the last context bank for its own use, thus a simple work-around is: DON'T USE IT in Linux.
If we decrease the number of context banks, last one will be "hidden".

SDM845's Adreno SMMU is unique in that it actually advertizes support for 16K (and 32M) pages, which doesn't hold for newer SoCs.
This however, seems either broken in the hardware implementation, the hypervisor middleware that abstracts the SMMU, or there's a bug in the Linux kernel somewhere down the line that nobody managed to track down.
Booting SDM845 with 16K page sizes and drm/msm results in:
*** gpu fault: ttbr0=0000000000000000 iova=000100000000c000 dir=READ type=TRANSLATION source=CP (0,0,0,0)
right after loading the firmware. The GPU then starts spitting out illegal intstruction errors, as it's quite obvious that it got a bogus pointer.
Moreover, it seems like this issue also concerns other implementations of SMMUv2 on Qualcomm SoCs, such as the one on SC7180.
Hide 16K support on such instances to work around this.

According to the spec (ARM IHI 0070 F.b), in "5.5 Fault configuration (A, R, S bits)": A STE with stage 2 translation enabled and STE.S2S == 0 is considered ILLEGAL if SMMU_IDR0.STALL_MODEL == 0b10.
Also described in the pseudocode “SteIllegal()” if STE.Config == '11x' then [..] if eff_idr0_stall_model == '10' && STE.S2S == '0' then // stall_model forcing stall, but S2S == 0 return TRUE;
Which means, S2S must be set when stall model is "ARM_SMMU_FEAT_STALL_FORCE", but currently the driver ignores that.
Although, the driver can do the minimum and only set S2S for “ARM_SMMU_FEAT_STALL_FORCE”, it is more consistent to match S1 behaviour, which also sets it for “ARM_SMMU_FEAT_STALL” if the master has requested stalls.
Also, since S2 stalls are enabled now, report them to the IOMMU layer and for VFIO devices it will fail anyway as VFIO doesn’t register an iopf handler.

If qi_submit_sync() is invoked with 0 invalidation descriptors (for instance, for DMA draining purposes), we can run into a bug where a submitting thread fails to detect the completion of invalidation_wait. Subsequently, this led to a soft lockup. Currently, there is no impact by this bug on the existing users because no callers are submitting invalidations with 0 descriptors. This fix will enable future users (such as DMA drain) calling qi_submit_sync() with 0 count.
Suppose thread T1 invokes qi_submit_sync() with non-zero descriptors, while concurrently, thread T2 calls qi_submit_sync() with zero descriptors. Both threads then enter a while loop, waiting for their respective descriptors to complete. T1 detects its completion (i.e., T1's invalidation_wait status changes to QI_DONE by HW) and proceeds to call reclaim_free_desc() to reclaim all descriptors, potentially including adjacent ones of other threads that are also marked as QI_DONE.
During this time, while T2 is waiting to acquire the qi->q_lock, the IOMMU hardware may complete the invalidation for T2, setting its status to QI_DONE. However, if T1's execution of reclaim_free_desc() frees T2's invalidation_wait descriptor and changes its status to QI_FREE, T2 will not observe the QI_DONE status for its invalidation_wait and will indefinitely remain stuck.
This soft lockup does not occur when only non-zero descriptors are submitted.In such cases, invalidation descriptors are interspersed among wait descriptors with the status QI_IN_USE, acting as barriers. These barriers prevent the reclaim code from mistakenly freeing descriptors belonging to other submitters.
Considered the following example timeline: T1 T2 ======================================== ID1 WD1 while(WD1!=QI_DONE) unlock lock WD1=QI_DONE* WD2 while(WD2!=QI_DONE) unlock lock WD1==QI_DONE? ID1=QI_DONE WD2=DONE* reclaim() ID1=FREE WD1=FREE WD2=FREE unlock soft lockup! T2 never sees QI_DONE in WD2
Where: ID = invalidation descriptor WD = wait descriptor * Written by hardware
The root of the problem is that the descriptor status QI_DONE flag is used for two conflicting purposes: 1. signal a descriptor is ready for reclaim (to be freed) 2. signal by the hardware that a wait descriptor is complete
The solution (in this patch) is state separation by using QI_FREE flag for #1.
Once a thread's invalidation descriptors are complete, their status would be set to QI_FREE. The reclaim_free_desc() function would then only free descriptors marked as QI_FREE instead of those marked as QI_DONE. This change ensures that T2 (from the previous example) will correctly observe the completion of its invalidation_wait (marked as QI_DONE).

[ Upstream commit 1f5e307ca16c0c19186cbd56ac460a687e6daba0 ]
The caching mode of an IOMMU is irrelevant to the behavior of the device TLB. Previously, commit <304b3bde24b5> ("iommu/vt-d: Remove caching mode check before device TLB flush") removed this redundant check in the domain unmap path.
Checking the caching mode before flushing the device TLB after a pasid table entry is updated is unnecessary and can lead to inconsistent behavior.
Extends this consistency by removing the caching mode check in the pasid table update path.

The master->cd_table is entirely contained within the struct arm_smmu_master which is guaranteed to be freed by the core code under arm_smmu_release_device().
There is no reason to use devm here, arm_smmu_free_cd_tables() is reliably called to free the CD related memory. Remove it and save some memory.

The configs that disable some v1 controllers would still allow mounting them but with no controller-specific files. (Making such hierarchies equivalent to named v1 hierarchies.) To achieve behavior consistent with actual out-compilation of a whole controller, the mounts should treat respective controllers as non-existent.
Wrap implementation into a helper function, leverage legacy_files to detect compiled out controllers. The effect is that mounts on v1 would fail and produce a message like: [ 1543.999081] cgroup: Unknown subsys name 'memory'

[WHAT & HOW] These pointers are null checked previously in the same function, indicating they might be null as reported by Coverity. As a result, they need to be checked when used again.
This fixes 3 FORWARD_NULL issue reported by Coverity.

Before this commit, only submits with both a BO_HANDLES chunk and a 'bo_list_handle' would be rejected (by amdgpu_cs_parser_bos).
But if UMD sent multiple BO_HANDLES, what would happen is: * only the last one would be really used * all the others would leak memory as amdgpu_cs_p1_bo_handles would overwrite the previous p->bo_list value
This commit rejects submissions with multiple BO_HANDLES chunks to match the implementation of the parser.

[ Upstream commit 66d71a72539e173a9b00ca0b1852cbaa5f5bf1ad ]
This commit addresses a null pointer dereference issue in the `commit_planes_for_stream` function at line 4140. The issue could occur when `top_pipe_to_program` is null.
The fix adds a check to ensure `top_pipe_to_program` is not null before accessing its stream_res. This prevents a null pointer dereference.
Reported by smatch: drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc.c:4140 commit_planes_for_stream() error: we previously assumed 'top_pipe_to_program' could be null (see line 3906)

Let's not use the term blacklist in the function serverworks_osb4_filter() documentation comment and rather simply refer to what that function looks at: the list of devices with groken UDMA5.
While at it, also constify the values of the csb_bad_ata100 array.
Of note is that all of this should probably be handled using libata quirk mechanism but it is unclear if these UDMA5 quirks are specific to this controller only.

[ Upstream commit bcc31692a1d1e21f0d06c5f727c03ee299d2264e ]
Before this change there were 16 vid:pid based quirks to ignore the battery reported by Elan I2C-HID touchscreens on various Asus and HP laptops.
And a report has been received that the 04F3:2A00 I2C touchscreen on the HP ProBook x360 11 G5 EE/86CF also reports a non present battery.
Since I2C-HID devices are always builtin to laptops they are not battery owered so it should be safe to just ignore the battery on all Elan I2C-HID devices, rather then adding a 17th quirk for the 04F3:2A00 touchscreen.
As reported in the changelog of commit a3a5a37efba1 ("HID: Ignore battery for ELAN touchscreens 2F2C and 4116"), which added 2 new Elan touchscreen quirks about a month ago, the HID reported battery seems to be related to a stylus being used. But even when a stylus is in use it does not properly report the charge of the stylus battery, instead the reported battery charge jumps from 0% to 1%. So it is best to just ignore the HID battery.

This commit adds a null check for the set_output_gamma function pointer in the dcn20_set_output_transfer_func function. Previously, set_output_gamma was being checked for null at line 1030, but then it was being dereferenced without any null check at line 1048. This could potentially lead to a null pointer dereference error if set_output_gamma is null.
To fix this, we now ensure that set_output_gamma is not null before dereferencing it. We do this by adding a null check for set_output_gamma before the call to set_output_gamma at line 1048.

[Analysis] There are two paths (dbUnmount and jfs_ioc_trim) that generate race condition when accessing bmap, which leads to the occurrence of uaf.
Use the lock s_umount to synchronize them, in order to avoid uaf caused by race condition.

[ Upstream commit 4c76114932d1d6fad2e72823e7898a3c960cf2a7 ]
Correct stream detection by initializing the structure pqi_scsi_dev_raid_map_data to 0s.
When the OS issues SCSI READ commands, the driver erroneously considers them as SCSI WRITES. If they are identified as sequential IOs, the driver then submits those requests via the RAID path instead of the AIO path.
The 'is_write' flag might be set for SCSI READ commands also. The driver may interpret SCSI READ commands as SCSI WRITE commands, resulting in IOs being submitted through the RAID path.
Note: This does not cause data corruption.

[ Upstream commit 16007768551d5bfe53426645401435ca8d2ef54f ]
There are some cases, such as the one uncovered by Commit 46d4efcccc68 ("drm/msm/a6xx: Avoid a nullptr dereference when speedbin setting fails") where
msm_gpu_cleanup() : platform_set_drvdata(gpu->pdev, NULL);
is called on gpu->pdev == NULL, as the GPU device has not been fully initialized yet.
Turns out that there's more than just the aforementioned path that causes this to happen (e.g. the case when there's speedbin data in the catalog, but opp-supported-hw is missing in DT).
Assigning msm_gpu->pdev earlier seems like the least painful solution to this, therefore do so.

sampling_rate is an uint8_t but is assigned an unsigned int, and thus it can overflow. As a result, sampling_rate is changed to uint32_t.
Similarly, LINK_QUAL_PATTERN_SET has a size of 2 bits, and it should only be assigned to a value less or equal than 4.
This fixes 2 INTEGER_OVERFLOW issues reported by Coverity.

We want to determine the size of the devcoredump before writing it out. To that end, we will run the devcoredump printer with NULL data to get the size, alloc data based on the generated offset, then run the devcorecump again with a valid data pointer to print. This necessitates not writing data to the data pointer on the initial pass, when it is NULL.

[ Upstream commit cfa7f3d2c526c224a6271cc78a4a27a0de06f4f0 ]
When tracing user functions with uprobe functionality, it's common to install the probe (e.g., a BPF program) at the first instruction of the function. This is often going to be `push %rbp` instruction in function preamble, which means that within that function frame pointer hasn't been established yet. This leads to consistently missing an actual caller of the traced function, because perf_callchain_user() only records current IP (capturing traced function) and then following frame pointer chain (which would be caller's frame, containing the address of caller's caller).
So when we have target_1 -> target_2 -> target_3 call chain and we are tracing an entry to target_3, captured stack trace will report target_1 -> target_3 call chain, which is wrong and confusing.
This patch proposes a x86-64-specific heuristic to detect `push %rbp` (`push %ebp` on 32-bit architecture) instruction being traced. Given entire kernel implementation of user space stack trace capturing works under assumption that user space code was compiled with frame pointer register (%rbp/%ebp) preservation, it seems pretty reasonable to use this instruction as a strong indicator that this is the entry to the function. In that case, return address is still pointed to by %rsp/%esp, so we fetch it and add to stack trace before proceeding to unwind the rest using frame pointer-based logic.
We also check for `endbr64` (for 64-bit modes) as another common pattern for function entry, as suggested by Josh Poimboeuf. Even if we get this wrong sometimes for uprobes attached not at the function entry, it's OK because stack trace will still be overall meaningful, just with one extra bogus entry. If we don't detect this, we end up with guaranteed to be missing caller function entry in the stack trace, which is worse overall.

struct aac_srb_unit contains struct aac_srb, which contains struct sgmap, which ends in a (currently) "fake" (1-element) flexible array. Converting this to a flexible array is needed so that runtime bounds checking won't think the array is fixed size (i.e. under CONFIG_FORTIFY_SOURCE=y and/or CONFIG_UBSAN_BOUNDS=y), as other parts of aacraid use struct sgmap as a flexible array.
It is not legal to have a flexible array in the middle of a structure, so it either needs to be split up or rearranged so that it is at the end of the structure. Luckily, struct aac_srb_unit, which is exclusively consumed/updated by aac_send_safw_bmic_cmd(), does not depend on member ordering.
The values set in the on-stack struct aac_srb_unit instance "srbu" by the only two callers, aac_issue_safw_bmic_identify() and aac_get_safw_ciss_luns(), do not contain anything in srbu.srb.sgmap.sg, and they both implicitly initialize srbu.srb.sgmap.count to 0 during memset(). For example:
memset(&srbu, 0, sizeof(struct aac_srb_unit));
srbcmd = &srbu.srb; srbcmd->flags = cpu_to_le32(SRB_DataIn); srbcmd->cdb[0] = CISS_REPORT_PHYSICAL_LUNS; srbcmd->cdb[1] = 2; /* extended reporting */ srbcmd->cdb[8] = (u8)(datasize >> 8); srbcmd->cdb[9] = (u8)(datasize);
rcode = aac_send_safw_bmic_cmd(dev, &srbu, phys_luns, datasize);
During aac_send_safw_bmic_cmd(), a separate srb is mapped into DMA, and has srbu.srb copied into it:
srb = fib_data(fibptr); memcpy(srb, &srbu->srb, sizeof(struct aac_srb));
Only then is srb.sgmap.count written and srb->sg populated:
srb->count = cpu_to_le32(xfer_len);
sg64 = (struct sgmap64 *)&srb->sg; sg64->count = cpu_to_le32(1); sg64->sg[0].addr[1] = cpu_to_le32(upper_32_bits(addr)); sg64->sg[0].addr[0] = cpu_to_le32(lower_32_bits(addr)); sg64->sg[0].count = cpu_to_le32(xfer_len);
But this is happening in the DMA memory, not in srbu.srb. An attempt to copy the changes back to srbu does happen:
/* * Copy the updated data for other dumping or other usage if * needed */ memcpy(&srbu->srb, srb, sizeof(struct aac_srb));
But this was never correct: the sg64 (3 u32s) overlap of srb.sg (2 u32s) always meant that srbu.srb would have held truncated information and any attempt to walk srbu.srb.sg.sg based on the value of srbu.srb.sg.count would result in attempting to parse past the end of srbu.srb.sg.sg[0] into srbu.srb_reply.
After getting a reply from hardware, the reply is copied into srbu.srb_reply:
srb_reply = (struct aac_srb_reply *)fib_data(fibptr); memcpy(&srbu->srb_reply, srb_reply, sizeof(struct aac_srb_reply));
This has always been fixed-size, so there's no issue here. It is worth noting that the two callers _never check_ srbu contents -- neither srbu.srb nor srbu.srb_reply is examined. (They depend on the mapped xfer_buf instead.)
Therefore, the ordering of members in struct aac_srb_unit does not matter, and the flexible array member can moved to the end.
(Additionally, the two memcpy()s that update srbu could be entirely removed as they are never consumed, but I left that as-is.)

When the HBA is undergoing a reset or is handling an errata event, NULL ptr dereference crashes may occur in routines such as lpfc_sli_flush_io_rings(), lpfc_dev_loss_tmo_callbk(), or lpfc_abort_handler().
Add NULL ptr checks before dereferencing hdwq pointers that may have been freed due to operations colliding with a reset or errata event handler.

In direct attached topology, certain target vendors that are quick to issue FLOGI followed by a cable pull for more than dev_loss_tmo may result in a kref imbalance for the remote port ndlp object.
Add an nlp_get when the defer_flogi_acc flag is set. This is expected to balance the nlp_put in the defer_flogi_acc clause in the lpfc_issue_els_flogi() routine. Because we need to retain the ndlp ptr, reorganize all of the defer_flogi_acc information into one lpfc_defer_flogi_acc struct.

A kref imbalance occurs when handling an unsolicited PRLO in direct attached topology.
Rework PRLO rcv handling when in MAPPED state. Save the state that we were handling a PRLO by setting nlp_last_elscmd to ELS_CMD_PRLO. Then in the lpfc_cmpl_els_logo_acc() completion routine, manually restart discovery. By issuing the PLOGI, which nlp_gets, before nlp_put at the end of the lpfc_cmpl_els_logo_acc() routine, we are saving us from a final nlp_put. And, we are still allowing the unreg_rpi to happen.

Fix this by converting the if/else if/... construct into a proper switch() statement with a default to handle the error case.
As a bonus, the generated code is ca. 100 bytes smaller (with gcc 11.4.0 targeting arm32).

Currently the page fault queue size is hard coded. However the hardware supports faulting for each EU and each CS. For some applications running on hardware with a large number of EUs and CSs, this can result in an overflow of the page fault queue.
Add a small calculation to determine the page fault queue size based on the number of EUs and CSs in the platform as detmined by fuses.

_be32 type is defined for some elements in pseries_hp_errorlog struct but also used them u32 after be32_to_cpu() conversion.
Example: In handle_dlpar_errorlog() hp_elog->_drc_u.drc_index = be32_to_cpu(hp_elog->_drc_u.drc_index);
And later assigned to u32 type dlpar_cpu() - u32 drc_index = hp_elog->_drc_u.drc_index;
This incorrect usage is giving the following warnings and the patch resolve these warnings with the correct assignment.

[ Upstream commit 7d6899fb69d25e1bc6f4700b7c1d92e6b608593d ]
For upper filesystems which do not use strict ordering of persisting metadata changes (e.g. ubifs), when overlayfs file is modified for the first time, copy up will create a copy of the lower file and its parent directories in the upper layer. Permission lost of the new upper parent directory was observed during power-cut stress test.
Fix by moving the fsync call to after metadata copy to make sure that the metadata copied up directory and files persists to disk before renaming from tmp to final destination.
With metacopy enabled, this change will hurt performance of workloads such as chown -R, so we keep the legacy behavior of fsync only on copyup of data.

[ Upstream commit d9dca215708d32e7f88ac0591fbb187cbf368adb ]
While booting, Lenovo 14ARB7 reports 'lenovo-ymc: Unknown key 0 pressed' warning. This is caused by lenovo_ymc_probe() calling lenovo_ymc_notify() at probe time to get the initial tablet-mode-switch state and the key-code lenovo_ymc_notify() reads from the firmware is not initialized at probe time yet on the Lenovo 14ARB7.
The hardware/firmware does an ACPI notify on the WMI device itself when it initializes the tablet-mode-switch state later on.
Add 0x0 YMC state to the sparse keymap to silence the warning.

[ Upstream commit b4ed18a3d56eabd18cfd9841ff05111e3cfbe8f9 ]
i2c-hid uses 2 shared buffers: command and "raw" input buffer for sending requests to peripherals and read data from peripherals when executing variety of commands. Such commands include reading of HID registers, requesting particular power mode, getting and setting reports and so on. Because all such requests use the same 2 buffers they should not execute simultaneously.
Fix this by introducing "cmd_lock" mutex and acquire it whenever we needs to access ihid->cmdbuf or idid->rawbuf.

When sending an oplock break request, opinfo->conn is used, But freed ->conn can be used on multichannel. This patch add a reference count to the ksmbd_conn struct so that it can be freed when it is no longer used.

[ Upstream commit df40a23cc34c200cfde559eda7ca540f3ae7bd9e ]
The "input-events" LED trigger used to turn on the backlight LEDs had to be rewritten to use led_trigger_register_simple() + led_trigger_event() to fix a serious locking issue.
This means it no longer supports using blink_brightness to set a per LED brightness for the trigger and it no longer sets LED_CORE_SUSPENDRESUME.
Adjust the MiPad 2 bottom bezel touch buttons LED class device to match:
1. Make LED_FULL the maximum brightness to fix the LED brightness being very low when on. 2. Set flags = LED_CORE_SUSPENDRESUME.

When the filesystem is mounted with errors=remount-ro, we were setting SB_RDONLY flag to stop all filesystem modifications. We knew this misses proper locking (sb->s_umount) and does not go through proper filesystem remount procedure but it has been the way this worked since early ext2 days and it was good enough for catastrophic situation damage mitigation. Recently, syzbot has found a way (see link) to trigger warnings in filesystem freezing because the code got confused by SB_RDONLY changing under its hands. Since these days we set EXT4_FLAGS_SHUTDOWN on the superblock which is enough to stop all filesystem modifications, modifying SB_RDONLY shouldn't be needed. So stop doing that.

Currently we cannot pass the pointer returned by iter next method as argument to KF_TRUSTED_ARGS or KF_RCU kfuncs, because the pointer returned by iter next method is not "valid".
This patch sets the pointer returned by iter next method to be valid.
This is based on the fact that if the iterator is implemented correctly, then the pointer returned from the iter next method should be valid.
This does not make NULL pointer valid. If the iter next method has KF_RET_NULL flag, then the verifier will ask the ebpf program to check NULL pointer.
KF_RCU_PROTECTED iterator is a special case, the pointer returned by iter next method should only be valid within RCU critical section, so it should be with MEM_RCU, not PTR_TRUSTED.
Another special case is bpf_iter_num_next, which returns a pointer with base type PTR_TO_MEM. PTR_TO_MEM should not be combined with type flag PTR_TRUSTED (PTR_TO_MEM already means the pointer is valid).
The pointer returned by iter next method of other types of iterators is with PTR_TRUSTED.
In addition, this patch adds get_iter_from_state to help us get the current iterator from the current state.

[ Upstream commit 10553a91652d995274da63fc317470f703765081 ]
iomap_dio_zero() will pad a fs block with zeroes if the direct IO size < fs block size. iomap_dio_zero() has an implicit assumption that fs block size < page_size. This is true for most filesystems at the moment.
If the block size > page size, this will send the contents of the page next to zero page(as len > PAGE_SIZE) to the underlying block device, causing FS corruption.
iomap is a generic infrastructure and it should not make any assumptions about the fs block size and the page size of the system.

ext4_search_dir currently returns -1 in case of a failure, while it returns 0 when the name is not found. In such failure cases, it should return an error code instead.
This becomes even more important when ext4_find_inline_entry returns an error code as well in the next commit.
-EFSCORRUPTED seems appropriate as such error code as these failures would be caused by unexpected record lengths and is in line with other instances of ext4_check_dir_entry failures.
In the case of ext4_dx_find_entry, the current use of ERR_BAD_DX_DIR was left as is to reduce the risk of regressions.

In ext4_find_extent(), path may be freed by error or be reallocated, so using a previously saved *ppath may have been freed and thus may trigger use-after-free, as follows:
ext4_split_extent path = *ppath; ext4_split_extent_at(ppath) path = ext4_find_extent(ppath) ext4_split_extent_at(ppath) // ext4_find_extent fails to free path // but zeroout succeeds ext4_ext_show_leaf(inode, path) eh = path[depth].p_hdr // path use-after-free !!!
Similar to ext4_split_extent_at(), we use *ppath directly as an input to ext4_ext_show_leaf(). Fix a spelling error by the way.
Same problem in ext4_ext_handle_unwritten_extents(). Since 'path' is only used in ext4_ext_show_leaf(), remove 'path' and use *ppath directly.
This issue is triggered only when EXT_DEBUG is defined and therefore does not affect functionality.

[ Upstream commit cc749e61c011c255d81b192a822db650c68b313f ]
Fuzzing reports a possible deadlock in jbd2_log_wait_commit.
This issue is triggered when an EXT4_IOC_MIGRATE ioctl is set to require synchronous updates because the file descriptor is opened with O_SYNC. This can lead to the jbd2_journal_stop() function calling jbd2_might_wait_for_commit(), potentially causing a deadlock if the EXT4_IOC_MIGRATE call races with a write(2) system call.
This problem only arises when CONFIG_PROVE_LOCKING is enabled. In this case, the jbd2_might_wait_for_commit macro locks jbd2_handle in the jbd2_journal_stop function while i_data_sem is locked. This triggers lockdep because the jbd2_journal_start function might also lock the same jbd2_handle simultaneously.

Replace shifts of '1' with '1U' in bitwise operations within __show_dev_tc_bpf() to prevent undefined behavior caused by shifting into the sign bit of a signed integer. By using '1U', the operations are explicitly performed on unsigned integers, avoiding potential integer overflow or sign-related issues.

When direct I/O completions invalidates the page cache it holds neither the i_rwsem nor the invalidate_lock so it can be racing with iomap_write_delalloc_release. If the search for the end of the region that contains data returns the start offset we hit such a race and just need to look for the end of the newly created hole instead.

When netfilter has no entry to display, qsort is called with qsort(NULL, 0, ...). This results in undefined behavior, as UBSan reports:
net.c:827:2: runtime error: null pointer passed as argument 1, which is declared to never be null
Although the C standard does not explicitly state whether calling qsort with a NULL pointer when the size is 0 constitutes undefined behavior, Section 7.1.4 of the C standard (Use of library functions) mentions:
"Each of the following statements applies unless explicitly stated otherwise in the detailed descriptions that follow: If an argument to a function has an invalid value (such as a value outside the domain of the function, or a pointer outside the address space of the program, or a null pointer, or a pointer to non-modifiable storage when the corresponding parameter is not const-qualified) or a type (after promotion) not expected by a function with variable number of arguments, the behavior is undefined."
To avoid this, add an early return when nf_link_info is NULL to prevent calling qsort with a NULL pointer.

Zac Ecob reported a problem where a bpf program may cause kernel crash due to the following error: Oops: divide error: 0000 [#1] PREEMPT SMP KASAN PTI
The failure is due to the below signed divide: LLONG_MIN/-1 where LLONG_MIN equals to -9,223,372,036,854,775,808. LLONG_MIN/-1 is supposed to give a positive number 9,223,372,036,854,775,808, but it is impossible since for 64-bit system, the maximum positive number is 9,223,372,036,854,775,807. On x86_64, LLONG_MIN/-1 will cause a kernel exception. On arm64, the result for LLONG_MIN/-1 is LLONG_MIN.
Further investigation found all the following sdiv/smod cases may trigger an exception when bpf program is running on x86_64 platform: - LLONG_MIN/-1 for 64bit operation - INT_MIN/-1 for 32bit operation - LLONG_MIN%-1 for 64bit operation - INT_MIN%-1 for 32bit operation where -1 can be an immediate or in a register.
On arm64, there are no exceptions: - LLONG_MIN/-1 = LLONG_MIN - INT_MIN/-1 = INT_MIN - LLONG_MIN%-1 = 0 - INT_MIN%-1 = 0 where -1 can be an immediate or in a register.
Insn patching is needed to handle the above cases and the patched codes produced results aligned with above arm64 result. The below are pseudo codes to handle sdiv/smod exceptions including both divisor -1 and divisor 0 and the divisor is stored in a register.
