Checking at both msm8909-pm8916.dtsi and msm8916.dtsi from downstream
it is indicated that "batt_id" channel has to be scaled with the default
function:
chan@31 {
label = "batt_id";
reg = <0x31>;
qcom,decimation = <0>;
qcom,pre-div-channel-scaling = <0>;
qcom,calibration-type = "ratiometric";
qcom,scale-function = <0>;
qcom,hw-settle-time = <0xb>;
qcom,fast-avg-setup = <0>;
};
Change LR_MUX2_BAT_ID scaling accordingly.

Fixes a wrong bit mask used for the ADC's result, which was caused by an improper usage of the GENMASK() macro. The bits higher than ADC's resolution are undefined and if not masked out correctly, a wrong result can be given. The GENMASK() macro indexing is zero based, so the mask has to go from [resolution - 1 , 0].

The ceiling value isn't checked before writing it into registers. The user could write a value higher than the counter resolution (e.g. 16 or 32 bits indicated by max_arr). This makes most significant bits to be truncated. Fix it by checking the max_arr to report a range error [1] to the user.

…ster Ceiling value may be miss-aligned with what's actually configured into the ARR register. This is seen after probe as currently the ARR value is zero, whereas ceiling value is set to the maximum. So: - reading ceiling reports zero - in case the counter gets enabled without any prior configuration, it won't count. - in case the function gets set by the user 1st, (priv->ceiling) is used. Fix it by getting rid of the cached "priv->ceiling" variable. Rather use the ARR register value directly by using regmap read or write when needed. There should be no drawback on performance as priv->ceiling isn't used in performance critical path. There's also no point in writing ARR while setting function (sms), so it can be safely removed.

When generic/371 is run on kvm-xfstests using 5.10 and 5.11 kernels, it fails at significant rates on the two test scenarios that disable delayed allocation (ext3conv and data_journal) and force actual block allocation for the fallocate and pwrite functions in the test. The failure rate on 5.10 for both ext3conv and data_journal on one test system typically runs about 85%. On 5.11, the failure rate on ext3conv sometimes drops to as low as 1% while the rate on data_journal increases to nearly 100%. The observed failures are largely due to ext4_should_retry_alloc() cutting off block allocation retries when s_mb_free_pending (used to indicate that a transaction in progress will free blocks) is 0. However, free space is usually available when this occurs during runs of generic/371. It appears that a thread attempting to allocate blocks is just missing transaction commits in other threads that increase the free cluster count and reset s_mb_free_pending while the allocating thread isn't running. Explicitly testing for free space availability avoids this race. The current code uses a post-increment operator in the conditional expression that determines whether the retry limit has been exceeded. This means that the conditional expression uses the value of the retry counter before it's increased, resulting in an extra retry cycle. The current code actually retries twice before hitting its retry limit rather than once. Increasing the retry limit to 3 from the current actual maximum retry count of 2 in combination with the change described above reduces the observed failure rate to less that 0.1% on both ext3conv and data_journal with what should be limited impact on users sensitive to the overhead caused by retries. A per filesystem percpu counter exported via sysfs is added to allow users or developers to track the number of times the retry limit is exceeded without resorting to debugging methods. This should provide some insight into worst case retry behavior.

syzbot found UBSAN: shift-out-of-bounds in ext4_mb_init [1], when
1 << sbi->s_es->s_log_groups_per_flex is bigger than UINT_MAX,
where sbi->s_mb_prefetch is unsigned integer type.
32 is the maximum allowed power of s_log_groups_per_flex. Following if
check will also trigger UBSAN shift-out-of-bound:
if (1 << sbi->s_es->s_log_groups_per_flex >= UINT_MAX) {
So I'm checking it against the raw number, perhaps there is another way
to calculate UINT_MAX max power. Also use min_t as to make sure it's
uint type.

ext4 didn't properly clean up if verity failed to be enabled on a file: - It left verity metadata (pages past EOF) in the page cache, which would be exposed to userspace if the file was later extended. - It didn't truncate the verity metadata at all (either from cache or from disk) if an error occurred while setting the verity bit. Fix these bugs by adding a call to truncate_inode_pages() and ensuring that we truncate the verity metadata (both from cache and from disk) in all error paths. Also rework the code to cleanly separate the success path from the error paths, which makes it much easier to understand.

The code relies on constant folding of cpu_has_feature() based on possible and always true values as defined per CPU_FTRS_ALWAYS and CPU_FTRS_POSSIBLE. Build failure is encountered with for instance book3e_all_defconfig on kisskb in the AMDGPU driver which uses cpu_has_feature(CPU_FTR_VSX_COMP) to decide whether calling kernel_enable_vsx() or not. The failure is due to cpu_has_feature() not being inlined with that configuration with gcc 4.9.

Architectures that describe the CPU topology in devicetree and do not have an identity mapping between physical and logical CPU ids must override the default implementation of arch_match_cpu_phys_id(). Failing to do so breaks CPU devicetree-node lookups using of_get_cpu_node() and of_cpu_device_node_get() which several drivers rely on. It also causes the CPU struct devices exported through sysfs to point to the wrong devicetree nodes. On x86, CPUs are described in devicetree using their APIC ids and those do not generally coincide with the logical ids, even if CPU0 typically uses APIC id 0. Add the missing implementation of arch_match_cpu_phys_id() so that CPU-node lookups work also with SMP. Apart from fixing the broken sysfs devicetree-node links this likely does not affect current users of mainline kernels on x86.

With interrupt force threading all device interrupt handlers are invoked
from kernel threads. Contrary to hard interrupt context the invocation only
disables bottom halfs, but not interrupts. This was an oversight back then
because any code like this will have an issue:
thread(irq_A)
irq_handler(A)
spin_lock(&foo->lock);
interrupt(irq_B)
irq_handler(B)
spin_lock(&foo->lock);
This has been triggered with networking (NAPI vs. hrtimers) and console
drivers where printk() happens from an interrupt which interrupted the
force threaded handler.
Now people noticed and started to change the spin_lock() in the handler to
spin_lock_irqsave() which affects performance or add IRQF_NOTHREAD to the
interrupt request which in turn breaks RT.
Fix the root cause and not the symptom and disable interrupts before
invoking the force threaded handler which preserves the regular semantics
and the usefulness of the interrupt force threading as a general debugging
tool.
For not RT this is not changing much, except that during the execution of
the threaded handler interrupts are delayed until the handler
returns. Vs. scheduling and softirq processing there is no difference.
For RT kernels there is no issue.
Fixes: 8d32a30 ("genirq: Provide forced interrupt threading")

In ext4_rename(), when RENAME_WHITEOUT failed to add new entry into
directory, it ends up dropping new created whiteout inode under the
running transaction. After commit <9b88f9fb0d2> ("ext4: Do not iput inode
under running transaction"), we follow the assumptions that evict() does
not get called from a transaction context but in ext4_rename() it breaks
this suggestion. Although it's not a real problem, better to obey it, so
this patch add inode to orphan list and stop transaction before final
iput().

This patch adds rename whiteout support in fast commits. Note that the whiteout object that gets created is actually char device. Which imples, the function ext4_inode_journal_mode(struct inode *inode) would return "JOURNAL_DATA" for this inode. This has a consequence in fast commit code that it will make creation of the whiteout object a fast-commit ineligible behavior and thus will fall back to full commits. With this patch, this can be observed by running fast commits with rename whiteout and seeing the stats generated by ext4_fc_stats tracepoint as follows: ext4_fc_stats: dev 254:32 fc ineligible reasons: XATTR:0, CROSS_RENAME:0, JOURNAL_FLAG_CHANGE:0, NO_MEM:0, SWAP_BOOT:0, RESIZE:0, RENAME_DIR:0, FALLOC_RANGE:0, INODE_JOURNAL_DATA:16; num_commits:6, ineligible: 6, numblks: 3 So in short, this patch guarantees that in case of rename whiteout, we fall back to full commits. Amir mentioned that instead of creating a new whiteout object for every rename, we can create a static whiteout object with irrelevant nlink. That will make fast commits to not fall back to full commit. But until this happens, this patch will ensure correctness by falling back to full commits.

…with MSG_WAITALL Without that it's not safe to use them in a linked combination with others. Now combinations like IORING_OP_SENDMSG followed by IORING_OP_SPLICE should be possible. We already handle short reads and writes for the following opcodes: - IORING_OP_READV - IORING_OP_READ_FIXED - IORING_OP_READ - IORING_OP_WRITEV - IORING_OP_WRITE_FIXED - IORING_OP_WRITE - IORING_OP_SPLICE - IORING_OP_TEE Now we have it for these as well: - IORING_OP_SENDMSG - IORING_OP_SEND - IORING_OP_RECVMSG - IORING_OP_RECV For IORING_OP_RECVMSG we also check for the MSG_TRUNC and MSG_CTRUNC flags in order to call req_set_fail_links(). There might be applications arround depending on the behavior that even short send[msg]()/recv[msg]() retuns continue an IOSQE_IO_LINK chain. It's very unlikely that such applications pass in MSG_WAITALL, which is only defined in 'man 2 recvmsg', but not in 'man 2 sendmsg'. It's expected that the low level sock_sendmsg() call just ignores MSG_WAITALL, as MSG_ZEROCOPY is also ignored without explicitly set SO_ZEROCOPY. We also expect the caller to know about the implicit truncation to MAX_RW_COUNT, which we don't detect. cc: netdev@vger.kernel.org Link: https://lore.kernel.org/r/c4e1a4cc0d905314f4d5dc567e65a7b09621aab3.1615908477.git.metze@samba.org Signed-off-by: Stefan Metzmacher <metze@samba.org> Signed-off-by: Jens Axboe <axboe@kernel.dk>

Puranjay Mohan says: ==================== bpf, arm64: support for timed may_goto Changes in v2->v3: v2: https://lore.kernel.org/all/20250809204833.44803-1-puranjay@kernel.org/ - Rebased on bpf-next/master - Added Acked-by: tags from Xu and Kumar Changes in v1->v2: v1: https://lore.kernel.org/bpf/20250724125443.26182-1-puranjay@kernel.org/ - Added comment in arch_bpf_timed_may_goto() about BPF_REG_FP setup (Xu Kuohai) This set adds support for the timed may_goto instruction for the arm64. The timed may_goto instruction is implemented by the verifier by reserving 2 8byte slots in the program stack and then calling arch_bpf_timed_may_goto() in a loop with the stack offset of these two slots in BPF_REG_AX. It expects the function to put a timestamp in the first slot and the returned count in BPF_REG_AX is put into the second slot by a store instruction emitted by the verifier. arch_bpf_timed_may_goto() is special as it receives the parameter in BPF_REG_AX and is expected to return the result in BPF_REG_AX as well. It can't clobber any caller saved registers because verifier doesn't save anything before emitting the call. So, arch_bpf_timed_may_goto() is implemented in assembly so the exact registers that are stored/restored can be controlled (BPF caller saved registers here) and it also needs to take care of moving arguments and return values to and from BPF_REG_AX <-> arm64 R0. So, arch_bpf_timed_may_goto() acts as a trampoline to call bpf_check_timed_may_goto() which does the main logic of placing the timestamp and returning the count. All tests that use may_goto instruction pass after the changing some of them in patch 2 #404 stream_errors:OK [...] #406/2 stream_success/stream_cond_break:OK [...] #494/23 verifier_bpf_fastcall/may_goto_interaction_x86_64:SKIP #494/24 verifier_bpf_fastcall/may_goto_interaction_arm64:OK [...] #539/1 verifier_may_goto_1/may_goto 0:OK #539/2 verifier_may_goto_1/batch 2 of may_goto 0:OK #539/3 verifier_may_goto_1/may_goto batch with offsets 2/1/0:OK #539/4 verifier_may_goto_1/may_goto batch with offsets 2/0:OK #539 verifier_may_goto_1:OK #540/1 verifier_may_goto_2/C code with may_goto 0:OK #540 verifier_may_goto_2:OK Summary: 7/16 PASSED, 25 SKIPPED, 0 FAILED ==================== Link: https://patch.msgid.link/20250827113245.52629-1-puranjay@kernel.org Signed-off-by: Alexei Starovoitov <ast@kernel.org>
