Subject: [PATCH] can: gs_usb: increase max interface to U8_MAX
This issue was found by Runcheng Lu when develop HSCanT USB to CAN FD
converter[1]. The original developers may have only 3 interfaces
device to test so they write 3 here and wait for future change.
During the HSCanT development, we actually used 4 interfaces, so the
limitation of 3 is not enough now. But just increase one is not
future-proofed. Since the channel index type in gs_host_frame is u8,
just make canch[] become a flexible array with a u8 index, so it
naturally constraint by U8_MAX and avoid statically allocate 256
pointer for every gs_usb device.

In a past bug fix it was forgotten that entity access must be protected

Move the spin_unlock() to the appropriate position.

From: Benjamin Berg <benjamin.berg(a)intel.com>
The normal timer mechanism assume that timeout further in the future
need a lower accuracy. As an example, the granularity for a timer
scheduled 4096 ms in the future on a 1000 Hz system is already 512 ms.
This granularity is perfectly sufficient for e.g. timeouts, but there
are other types of events that will happen at a future point in time and
require a higher accuracy.
Add a new wiphy_hrtimer_work type that uses an hrtimer internally. The
API is almost identical to the existing wiphy_delayed_work and it can be
used as a drop-in replacement after minor adjustments. The work will be
scheduled relative to the current time with a slack of 1 millisecond.

When kvrealloc() fails, the original markers memory is leaked
because the function directly assigns the NULL to the markers pointer,
losing the reference to the original memory.
As a result, the kvfree() in pt_dump_init() ends up freeing NULL instead
of the previously allocated memory.
Fix this by using a temporary variable to store kvrealloc()'s return
value and only update the markers pointer on success.
Found via static anlaysis and this is similar to commit 42378a9ca553

Subject: [PATCH] vsock: fix lock inversion in vsock_assign_transport()
Syzbot reported a potential lock inversion deadlock between
vsock_register_mutex and sk_lock-AF_VSOCK when vsock_linger() is called.
The issue was introduced by commit 687aa0c5581b ("vsock: Fix
transport_* TOCTOU") which added vsock_register_mutex locking in
vsock_assign_transport() around the transport->release() call, that can
call vsock_linger(). vsock_assign_transport() can be called with sk_lock
held. vsock_linger() calls sk_wait_event() that temporarily releases and
re-acquires sk_lock. During this window, if another thread hold
vsock_register_mutex while trying to acquire sk_lock, a circular
dependency is created.
Fix this by releasing vsock_register_mutex before calling
transport->release() and vsock_deassign_transport(). This is safe
because we don't need to hold vsock_register_mutex while releasing the
old transport, and we ensure the new transport won't disappear by
obtaining a module reference first via try_module_get().

2.39.5 (Apple Git-154)
From: Wang Haoran <haoranwangsec(a)gmail.com>
commit 27e06650a5eafe832a90fd2604f0c5e920857fae upstream.
A buffer overflow arises from the usage of snprintf to write into the
buffer "buf" in target_lu_gp_members_show function located in
/drivers/target/target_core_configfs.c. This buffer is allocated with
size LU_GROUP_NAME_BUF (256 bytes).
snprintf(...) formats multiple strings into buf with the HBA name
(hba->hba_group.cg_item), a slash character, a devicename (dev->
dev_group.cg_item) and a newline character, the total formatted string
length may exceed the buffer size of 256 bytes.
Since snprintf() returns the total number of bytes that would have been
written (the length of %s/%sn ), this value may exceed the buffer length
(256 bytes) passed to memcpy(), this will ultimately cause function
memcpy reporting a buffer overflow error.
An additional check of the return value of snprintf() can avoid this
buffer overflow.

Subject: [PATCH] serial: sc16is7xx: remove useless enable of enhanced features
Commit 43c51bb573aa ("sc16is7xx: make sure device is in suspend once
probed") permanently enabled access to the enhanced features in
sc16is7xx_probe(), and it is never disabled after that.
Therefore, remove re-enable of enhanced features in
sc16is7xx_set_baud(). This eliminates a potential useless read + write
cycle each time the baud rate is reconfigured.

Need to talk to a real person Malaysia Airlines? Calling Malaysia Airlines directly at 📞 1-866-284-3022. Whether you are trying to make a flight change, cancel your booking, ask about baggage, or resolve a booking issue, reaching a live agent can save you time, stress, and confusion. While automated systems are useful for simple tasks, some situations just need a human touch.
In this guide, we will walk you through exactly how to reach a live person, what to prepare before calling, and alternate methods if the phone lines are busy.
☎️ First Things First: Call 1-866-284-3022
The most direct and reliable way to speak with a real Malaysia Airlines representative is by calling 📞 1-866-284-3022. This is Frontier’s official customer service number and should be your go-to for:
✈️ Flight changes or cancellations
🧾 Refund or credit questions
🛄 Baggage issues
🔁 Name corrections
🛑 Check-in or boarding problems
💺 Seat selection and upgrades
Pro Tip: When calling, try to do so during non-peak hours — early mornings or late evenings — to reduce your hold time.
🎧 How to Navigate the Automated Menu
When you call 1-866-284-3022, you will first hear an automated system. To get through to a live person faster, follow these steps:
Dial 1-866-284-3022
Wait for the automated greeting to begin
Press “1” for English (or “2” for Spanish)
Press “2” for existing reservations
Press “0” to speak with an agent (you may need to press "0" more than once)
👉 If “0” does not work immediately, stay on the line. Sometimes the system transfers you to an agent after a brief wait without needing more input.
If the lines are busy and you are placed on hold, do not hang up — wait times vary, but you will eventually reach someone.
🧾 What to Have Ready Before You Call
To help the agent assist you faster, make sure you have the following details on hand:
📌 Your confirmation code or booking number
📌 The full name on the reservation
📌 Your flight date and destination
📌 Any relevant documents (ID, credit card, etc.)
📌 A notepad for writing down instructions or confirmation numbers
If you are calling to fix a mistake or request a refund, be prepared to briefly explain the issue and possibly provide documentation via email upon request.
⏰ Best Times to Call 1-866-284-3022
Customer service lines can be busy, especially during:
⚠️ Holidays
⚠️ Severe weather or flight delays
⚠️ Early morning flight hours
🎯 For the best chance at a short wait, try calling during these times:
🕔 5:00 AM – 7:00 AM (EST)
🕘 9:00 PM – 11:00 PM (EST)
📅 Midweek (Tuesdays and Wednesdays)
Avoid Mondays if possible — it is the busiest day for airlines.
🧑💻 Alternative Ways to Reach Malaysia Airlines (If Phone Fails)
If calling 📞 1-866-284-3022 does not work or you are stuck in a long queue, here are a few alternate ways to get help:

Scroll down and look for the “Let’s Chat” option.

📧 2. Email Support
You can also submit a help request through their Customer Support Form online.
Use this for non-urgent matters like refund requests or documentation review.
📱 3. Social Media

While this will not guarantee a live agent, you might find answers to basic questions faster.

📞 For the fastest help, call Vietnam Airlines customer support at 1-866-284-3022. Their agents are trained to assist with name corrections.
✍️ Did you book a flight with Vietnam Airlines and realize your name is misspelled or needs updating? Whether it is a minor typo or a legal name change, it is essential to correct your flight details before travel to avoid problems at check-in. Fortunately, Vietnam Airlines offers options for name changes or corrections — and we are here to guide you through the process, step by step.
📌 Why Name Corrections Matter
Airlines require that the name on your ticket exactly matches the name on your government-issued ID or passport. Even a small typo can result in:
❌ Denied boarding
❌ TSA security issues
❌ Non-refundable tickets going to waste
That is why it is important to act quickly if you notice an error.
👉 Pro Tip: As soon as you spot an issue with your name, call 1-866-284-3022 to fix it directly with Vietnam Airlines.
📋 Vietnam Airlines Name Correction Policy: The Basics
Vietnam Airlines does allow name corrections and changes, but there are specific rules based on the type and extent of the correction.
✏️ Minor Name Corrections
If your correction is minor (e.g., spelling mistake, missing middle name, or nickname to legal name), it is usually easy to fix.
Examples:
• “Jonh” to “John”
• “Liz” to “Elizabeth”
• Missing middle name or incorrect initials
🟢 These are typically allowed once per passenger. Call 📞 1-866-284-3022 to request a minor correction. You may need to provide identification or legal documentation.
🔄 Major Name Changes
For legal name changes due to:
• Marriage 👰
• Divorce 💔
• Legal court order 📄
You will likely be required to submit legal documents (e.g., marriage certificate, divorce decree, or court papers).
Important: Name changes are different from transferring your ticket to someone else — Sun Country does not allow name transfers. The passenger must remain the same person.
📞 For clarity and assistance, it is best to speak to a representative at 1-866-284-3022.
💰 Are There Any Fees for Name Changes?
Yes, in most cases, Sun Country charges a name change or correction fee, which may vary depending on:
• The type of fare you purchased
• How close it is to your departure date
• Whether the change is made online or via customer service
Fees can range from $75 to $150, though minor corrections may be less, especially if made within 24 hours of booking.
🎯 To get an accurate quote and understand your options, call 1-866-284-3022 and speak with a Sun Country agent.
🌐 How to Request a Name Correction
There are two main ways to request a name correction on your Vietnam Airlines ticket:

📄 Provide your confirmation number, full incorrect name, and the correct name

Calling ensures faster processing and personalized help.

🚨 Urgent situations? Call 📞 1-866-284-3022 immediately. Sun Country's support team can walk you through your options quickly.
✍️ Final Checklist Before You Travel
✅ Name on your ticket matches your ID

🎧 How to Navigate the Automated Menu
When you call 1-866-284-3022, you will first hear an automated system. To get through to a live person faster, follow these steps:
Dial 1-866-284-3022
Wait for the automated greeting to begin
Press “1” for English (or “2” for Spanish)
Press “2” for existing reservations
Press “0” to speak with an agent (you may need to press "0" more than once)
👉 If “0” does not work immediately, stay on the line. Sometimes the system transfers you to an agent after a brief wait without needing more input.
If the lines are busy and you are placed on hold, do not hang up — wait times vary, but you will eventually reach someone.
🧾 What to Have Ready Before You Call
To help the agent assist you faster, make sure you have the following details on hand:
📌 Your confirmation code or booking number
📌 The full name on the reservation
📌 Your flight date and destination
📌 Any relevant documents (ID, credit card, etc.)
📌 A notepad for writing down instructions or confirmation numbers
If you are calling to fix a mistake or request a refund, be prepared to briefly explain the issue and possibly provide documentation via email upon request.
