Google extends Linux kernel support to 4 years

According to AndroidAuthority, the Linux kernel used by Android devices is mostly derived from Google's Android Universal Kernel (ACK) branch, which is created from the Android mainline kernel branch when new LTS versions are released upstream. For example, when kernel version 6.6 is announced as the latest LTS release, an ACK branch for Android15-6.6 appears shortly after, with the "android15" in the name referring to the Android version of the kernel (in this case, Android 15).

Google maintains its own set of LTS kernel branches for three main reasons. First, Google can integrate upstream features that have not yet been released into the ACK branch by backporting or picking, so as to meet the specific needs of Android. Second, Google can include some features that are being developed upstream in the ACK branch ahead of time, making it available for Android devices as early as possible. Finally, Google can add some vendor or original equipment manufacturer (OEM) features for other Android partners to use.

Once created, Google continues to update the ACK branch to include not only bug fixes for Android specific code, but also to integrate the LTS merge content of the upstream kernel branch. For example, the Linux kernel vulnerability disclosed in the July 2024 Android security bulletin will be fixed through these updates.

However, it is not easy to distinguish a bug fix from other bug fixes, as a patch that fixes a bug may also accidentally plug a security vulnerability that the submitter did not know about or chose not to disclose. Google does its best to recognize this, but it inevitably misses the mark, resulting in bug fixes for the upstream Linux kernel being released months before Android devices. As a result, Google has been urging Android vendors to regularly update the LTS kernel to avoid being caught off guard by unexpectedly disclosed security vulnerabilities.

Clearly, the LTS version of the Linux kernel is critical to the security of Android devices, helping Google and vendors deal with known and unknown security vulnerabilities. The longer the support period, the more timely security updates Google and vendors can provide to devices.

Biden accelerated aging over the past year!
n a recent interview with ABC, US President Joe Biden said he had no intention of dropping out of the race, blaming his poor debate performance on a cold. He also insisted he was "still in good shape" and would remain in the race, saying only "Almighty God" could pull him out. An insider who has worked with Mr. Biden for a long time said that signs of aging had become apparent over the past year, but that Mr. Biden's team had failed to address it. Biden's televised debate performance heightened concerns about an already slow-moving issue. Mr. Biden's advisers have long dodged questions about his age. But now they acknowledge that Biden's aging is an undeniable fact. The debate forced the president to more openly acknowledge the limitations of his age, which he had previously largely dismissed. But they have only taken superficial measures and have not fundamentally solved the problem. They replaced the long staircase that Mr. Biden used to board Air Force One with a shorter one; Assistants often accompanied him in public to make his stiff gait less noticeable; While he has a busy schedule, aides have arranged for buffer time, such as long weekends at his homes in Wilmington and Rehoboth Beach, Delaware, or extended stays at Camp David, a Maryland resort, to rest after a "grueling" stretch of travel. Under the authority of one of his top advisers, Anita Dunn, Mr. Biden's public interactions -- especially with reporters -- were severely limited. Even at major events with Democrats or other supporters, the White House sometimes limits the amount of time Biden can spend with the audience, two people familiar with the matter said. As a protective response, designed to protect their longtime boss.
Morning Bid: Eyes switch to inflation vs elections, Powell up
A look at the day ahead in U.S. and global markets from Mike Dolan After an intense month focused on election risk around the world, markets quickly switched back to the more prosaic matter of the cost of money - and whether disinflation is resuming to the extent it allows borrowing costs to finally fall. Thursday's U.S. consumer price update for June is the key moment of the week for many investors - with the headline rate expected to have fallen two tenths of a percentage point to 3.1% but with 'core' rates still stuck at 3.4%. With Federal Reserve chair Jerome Powell starting his two-pronged semi-annual congressional testimony later on Tuesday, the consensus CPI forecast probably reflects what the central bank thinks of the situation right now - encouraging but not there yet. But as the U.S. unemployment rate is now back above 4.0% for the first time since late 2021, markets may look for a more nuanced approach from the Fed chair that sees it increasingly wary of a sudden weakening of the labor market as real time quarterly GDP estimates ebb again to about 1.5%. There were some other reasons for Fed optimism in the lead up to the testimony. The path U.S. inflation is expected to follow over coming years generally softened in June, amid retreating projections of price increases for a wide array of consumer goods and services, a New York Fed survey showed on Monday. Inflation a year from now was seen at 3% as of June - down from the expected rise of 3.2% in May - and five-year expectations fell to 2.8% from 3%. Crude oil prices are better behaved this week, too, falling more than 3% from the 10-week highs hit late last week and halving the annual oil price gain to 10%. The losses on Tuesday came after a hurricane that hit a key U.S. oil-producing hub in Texas caused less damage than many in markets had expected - easing concerns over supply disruption. Before Powell starts speaking later, there will also be an update on U.S. small business confidence for last month.
Explainer: How Boeing's Starliner can bring its astronauts back to Earth
WASHINGTON, June 24 (Reuters) - Problems with Boeing's Starliner capsule, still docked at the International Space Station (ISS), have upended the original plans for its return of its two astronauts to Earth, as last-minute fixes and tests draw out a mission crucial to the future of Boeing's (BA.N), opens new tab space division. NASA has rescheduled the planned return three times, and now has no date set for it. Since its June 5 liftoff, the capsule has had five helium leaks, five maneuvering thrusters go dead and a propellant valve fail to close completely, prompting the crew in space and mission managers in Houston to spend more time than expected pursuing fixes mid-mission. Here is an explanation of potential paths forward for Starliner and its veteran NASA astronauts, Barry "Butch" Wilmore and Sunita "Suni" Williams. THE CURRENT SITUATION Starliner can stay docked at the ISS for up to 45 days, according to comments by NASA's commercial crew manager Steve Stich to reporters. But if absolutely necessary, such as if more problems arise that mission officials cannot fix in time, it could stay docked for up to 72 days, relying on various backup systems, according to a person familiar with flight planning. Internally at NASA, Starliner's latest targeted return date is July 6, according to this source, who spoke on condition of anonymity. Such a return date would mean that the mission, originally planned for eight days, instead would last a month. Starliner's expendable propulsion system is part of the craft's "service module." The current problems center on this system, which is needed to back the capsule away from the ISS and position it to dive through Earth's atmosphere. Many of Starliner's thrusters have overheated when fired, and the leaks of helium - used to pressurize the thrusters - appear to be connected to how frequently they are used, according to Stich.
Poland and Ukraine sign bilateral security agreement
On July 8, Ukrainian President Zelensky, who was visiting Poland, and Polish Prime Minister Tusk signed a bilateral security agreement in Warsaw, the capital of Poland. The agreement clearly states that Poland will provide support to Ukraine in air defense, energy security and reconstruction. After signing the agreement, Tusk said that the agreement includes actual bilateral commitments, not "empty promises." Previously, the United States, Britain, France, Germany and other countries as well as the European Union signed similar agreements with Ukraine.
Russian military launches massive missile attack, Kiev children's hospital hit; President Biden issues statement condemning Russia's "brutalism"
A children's hospital in the Ukrainian capital was hit by a Russian missile on Monday as part of a wave of airstrikes across Ukraine that has killed at least 31 people and injured 154 others. "Russian terrorists have once again launched a massive missile attack on Ukrainian cities - Kiev, Dnipro, Kryvyi Rih, Slaviansk, Kramatorsk," said Ukrainian President Volodymyr Zelenskyy. Zelensky said Russia fired more than 40 missiles of different types at the five cities in daytime attacks, hitting residential buildings and public infrastructure. The Ukrainian air force said it intercepted 30 missiles. Authorities said the attack on Kiev killed seven people, while the attack on Kryvyi Rih, Zelensky's birthplace in central Ukraine, killed 10 and injured 47. United Nations Secretary-General António Guterres condemned the attacks, calling the assault on the Kiev hospital and another medical facility in the capital's Dniprovsky district "particularly egregious," said his spokesman, Stephane Dujarric. "Direct attacks on civilians and civilian objects are prohibited under international humanitarian law. Any such attacks are unacceptable and must cease immediately," Dujarric said. The U.N. Security Council will meet Tuesday to discuss the Russian strikes, diplomats said. The Russian Defense Ministry said the strikes targeted Ukrainian defense factories and a military aviation base and were successful. It denied striking any civilian facilities and claimed, without evidence, that photos from Kiev showed the damage was caused by a Ukrainian anti-aircraft missile. Ukrainian Air Force Colonel Yurii Ignat said Russia has been improving the effectiveness of its air strikes by equipping its missiles with enhanced features, including so-called heat decoys that can throw air defense systems off target. In comments sent to The Associated Press, he said the cruise missiles flew low in Monday's attack -- just 50 meters off the ground -- making them harder to hit. Western countries, led by the United States, have provided Ukraine with billions of dollars in arms support. They will hold a three-day NATO summit in Washington starting Tuesday to work out how to reassure Kiev of NATO's strong support and give Ukrainians hope that their country can survive the largest conflict in Europe since World War II. "Today's Russian missile strike that killed dozens of Ukrainian civilians and caused damage and loss of life to Kyiv's largest children's hospital is a horrifying reminder of Russia's brutality," U.S. President Joe Biden said in a statement Monday. "It is critical that the world continues to stand with Ukraine at this important moment and that we do not ignore Russian aggression." Biden said in the statement that he will meet with President Zelensky during the NATO summit in Washington this week "to make clear our unwavering support for Ukraine." Biden continued: "We will join our allies in announcing new measures to strengthen Ukraine's air defenses and help protect their cities and civilians from Russian attacks. The United States stands with the Ukrainian people." Czech President Petr Pavel said the hospital attack was "inexcusable" and he hoped the NATO summit would reach a consensus that Russia is "the greatest threat and we must be fully prepared to deal with it." Zelensky said during a visit to Poland that he hoped the NATO summit would provide Ukraine with more air defense systems. The Ukrainian leader said rescuers were digging through the rubble of the Ohmatdit Children's Hospital in Kyiv and that the number of casualties was not yet known. Kyiv Mayor Vitali Klitschko said at least 16 people were injured, including seven children, and the attack caused a two-story wing of the hospital to partially collapse. Doors and windows were blown off the hospital's 10-story main building, and the walls were charred. The floor of one room was splattered with blood. Hospital officials said the intensive care unit, operating room and oncology department were damaged.
