[PATCH v2 0/3] dma-buf: heaps: cma: enable dmem cgroup accounting

by Eric Chanudet

An earlier series[1] from Maxime introduced dmem to the cma allocator in an attempt to use it generally for dma-buf. Restart from there and apply the charge in the narrower context of the CMA dma-buf heap instead. In line with introducing cgroup to the system heap[2], this behavior is enabled based on dma_heap.mem_accounting, disabled by default. dmem is chosen for CMA heaps as it allows limits to be set for each region backing each heap. The charge is only put in the dma-buf heap for now as it guaranties it can be accounted against a userspace process that requested the allocation.

[PATCH 0/7] dma-buf: heaps: Turn heaps into modules

by Maxime Ripard

Hi, The recent introduction of heaps in the optee driver [1] made possible the creation of heaps as modules. It's generally a good idea if possible, including for the already existing system and CMA heaps. The system one is pretty trivial, the CMA one is a bit more involved, especially since we have a call from kernel/dma/contiguous.c to the CMA heap code. This was solved by turning the logic around and making the CMA heap call into the contiguous DMA code. Let me know what you think, Maxime 1: https://lore.kernel.org/dri-devel/20250911135007.1275833-4-jens.wiklander@l… Signed-off-by: Maxime Ripard <mripard(a)kernel.org> --- Maxime Ripard (7): dma: contiguous: Turn heap registration logic around mm: cma: Export cma_alloc and cma_release mm: cma: Export cma_get_name mm: cma: Export dma_contiguous_default_area dma-buf: heaps: Export mem_accounting parameter dma-buf: heaps: cma: Turn the heap into a module dma-buf: heaps: system: Turn the heap into a module drivers/dma-buf/dma-heap.c | 1 + drivers/dma-buf/heaps/Kconfig | 4 ++-- drivers/dma-buf/heaps/cma_heap.c | 21 +++++---------------- drivers/dma-buf/heaps/system_heap.c | 5 +++++ include/linux/dma-map-ops.h | 5 +++++ kernel/dma/contiguous.c | 27 +++++++++++++++++++++++++-- mm/cma.c | 3 +++ 7 files changed, 46 insertions(+), 20 deletions(-) --- base-commit: 499a718536dc0e1c1d1b6211847207d58acd9916 change-id: 20260225-dma-buf-heaps-as-modules-1034b3ec9f2a Best regards, -- Maxime Ripard <mripard(a)kernel.org>

How to Recover a Stolen Bitcoin Wallet: Step-by-Step Guide for Victims in 2026

by hamtonbecky＠gmail.com

Discovering that your Bitcoin wallet has been stolen whether through phishing, malware, a compromised exchange account, or a leaked seed phrase—can feel devastating. Your Bitcoin, often viewed as digital gold, suddenly vanishes, and the irreversibility of blockchain transactions makes it seem hopeless. But in February 2026, recovery is possible in many cases, especially when you act quickly and use legitimate expertise. Here's a practical, step-by-step guide to recovering a stolen Bitcoin wallet, along with realistic expectations and prevention tips. Step 1: Confirm the Theft and Secure What's Left First, verify what happened. Check your wallet history on a trusted explorer like Blockchair or Blockchain.com. Look for unauthorized outgoing transactions. Immediately secure any remaining assets: move untouched Bitcoin to a new, clean wallet (preferably hardware like Ledger or Trezor). Revoke any suspicious approvals if the wallet supports it (e.g., using tools like Revoke.cash for connected dApps). Change passwords, enable 2FA (authenticator app, not SMS), and scan devices for malware. Step 2: Document Every Detail Gather evidence: transaction hashes (TXIDs), your wallet address, the thief's receiving addresses, timestamps, and any related scam communications (emails, chats, fake sites). Screenshots are crucial—include full transaction details showing amounts and dates. This evidence is essential for tracing and any legal action. Step 3: Report the Theft Immediately File a report with authorities: in the US, use the FBI's Internet Crime Complaint Center (IC3); in other countries, contact local cybercrime units. Report to the wallet provider or exchange if applicable (e.g., if keys were stolen from a hot wallet). Early reporting creates an official record and can trigger monitoring. Step 4: Understand Bitcoin Tracing Basics Bitcoin's UTXO model leaves clear trails. Investigators follow from your stolen transaction to downstream addresses, watching for splits (peeling), consolidations, or deposits to exchanges. Centralized exchanges are key choke points—many freeze funds if evidence proves theft. Step 5: Seek Legitimate Professional Help Do not pay upfront fees or share keys with unsolicited "recovery experts"—these are secondary scams. Legitimate firms assess viability first. Cryptera Chain Signals (CCS) is a trusted leader in stolen Bitcoin wallet recovery, with over 28 years of digital forensics experience, hundreds of successful cases, and a 4.28/5 rating from thousands of reviews in 2026. They specialize in real-time tracing, wallet clustering, and evidence preparation for exchange freezes or law enforcement—always with honest, no-pressure assessments and a focus on education (secure backups, multi-signature setups, phishing avoidance). Many clients recover significant portions when funds reach traceable endpoints. A victim who lost Bitcoin to malware shared: "CCS traced it to a deposit on Binance, prepared the report, and helped secure a freeze. I got 85% back and learned how to protect my wallet forever." Prevention for the Future Use hardware wallets offline, enable multi-sig, never store seeds digitally, verify addresses manually, and use transaction simulators. Regular backups and alerts can prevent most losses. If your Bitcoin wallet was stolen, act fast time is critical. Visit Cryptera Chain Signals at https://www.crypterachainsignals.com/ or email info(a)crypterachainsignals.com for a confidential consultation. Legitimate help can make a real difference.
