KERNEL RC3 LANDS WITH NETWORKING AND AUDIO FIXES, VETH ASYMMETRY BUG PATCHED

By RepoJournal · Filed · About Linux

The 7.1-rc3 merge window closes with critical fixes across networking, sound, and SELinux—including a nasty out-of-bounds queue access bug in veth that could corrupt XDP redirects.

Linus pulled net-7.1-rc3 [1] with fixes spanning Netfilter, IPsec, Bluetooth, and WiFi, plus corrections to recently-landed resizable hash tables that were causing regressions. The veth driver caught a serious bug [2] where asymmetric queue pairs would cause out-of-bounds access during XDP redirect operations—if a peer device has fewer TX queues than RX queues, the ring index calculation overflows, corrupting the transmit path. Sound subsystem also landed rc3 [3] fixing race conditions in deferred fasync checks and UMP group filtering in the sequencer, along with codec-specific cleanups in cs35l56 and tas2. SELinux merged policy file handling improvements [4] that allow multiple concurrent opens to /sys/fs/selinux/policy without blocking readers. The sparx5 network driver [5] got a fix for uninitialized serdes configuration on 1000BASE-X ports that was leaving devices pointed at high-speed blocks instead of shadow 2.5G devices.

What should Linux teams do about it?
If you're running veth with asymmetric queue counts and XDP redirects, apply the queue access fix immediately • Rebase any in-flight netdev patches on rc3 to catch resizable hash table corrections • Monitor sparx5 devices for port initialization after applying 1000BASE-X serdes fix
