#WasFehlt: vorgeschriebene #Kindersicherung bei #Koaxialkabel|n und #Kabelsanschluss-Dosen...

Denn so sieht das aus wenn ein [mutmaßliches Nachbars-] Kind mutmaßlich ne Büroklammer in ne Kabeldose klemmt:

Wenigstens ne Art Abdeckkappe wie bei Herdanschluss wäre 1NICE!

Und ja, #SharedMedia wie #GPON / #XGPON sind nur was #Funkstörungen angeht weniger problematisch als #DOCSIS-#Kabel!

Linux 6.15 will bring graphics improvements

Linux 6.15 is currently under development with a lot of promising changes, such as better support for PlayStation 5 controllers, lots of networking changes, and much more to come. It also brings the following key graphics and chipset improvements:

  • Added support for Apple Touch Bar for M1 and M2 MacBooks using the appletbdrm driver
  • Added the nova-core driver as a skeleton Rust driver
  • Added the DPCD eDP v1.5 definition
  • Added support for B140UAN04.4, BOE NV140FHM-NZ, CSW MNB601LS1-3, LG LP079QX1-SP0V, MNE007QS3-7, STA 116QHD024002, Starry 116KHD024006, Lenovo T14s Gen6 Snapdragon
  • Added support for CSOT PNA957QT1-1, Kingdisplay kd110n11-51ie, Starry 2082109qfh040022-50e
  • Added support for Raydium RM67200
  • Added support for BOE AV123Z7M-N17, BOE AV123Z7M-N17
  • Added driver for the Apple Summit display panel
  • Added driver for Visionox RM692E5
  • Added support for GC 11.5.2 + 11.5.3
  • Added support for SDMA 6.1.3
  • Added support for NBIO 7.9.1 + 7.11.2
  • Added support for MMHUB 1.8.1 + 3.3.2
  • Added support for DCN 3.6.0
  • Added support for G200eH5
  • Added support for the MT8365 SoC
  • Added support for MT8188 with DSC compatibility
  • Added support for rk3562-mali
  • Added support for AIC200
  • …alongside other improvements for existing devices

After updating to Linux 6.15, you will notice improved graphics performance across many areas, alongside the new features that this pull request brings.

Linux 6.15 will bring networking improvements

Linux 6.15 is currently under development with a lot of promising changes, such as better support for PlayStation 5 controllers, lots of graphics driver changes, Apple Touch Bar support, and much more to come. It also brings the following networking improvements for the core implementation:

  • Continue Netlink conversions to per-namespace RTNL lock (IPv4 routing, routing rules, routing next hops, ARP ioctls).
  • Continue extending the use of netdev instance locks.
  • Support collecting TCP timestamps (data submitted, sent, acked) in BPF, allowing for transparent (to the application) and lower overhead tracking of TCP RPC performance.
  • Tweak existing networking Rx zero-copy infra to support zero-copy Rx via io_uring.
  • Optimize MPTCP performance in single subflow mode by 29%.
  • Enable GRO on packets which went thru XDP CPU redirect (were queued for processing on a different CPU). Improving TCP stream performance up to 2x.
  • Improve performance of contended connect() by 200% by searching for an available 4-tuple under RCU rather than a spin lock.
  • Avoid unconditionally touching sk_tsflags on RX, improving performance under UDP flood by as much as 10%.
  • Avoid FIB lookup in netfilter if socket is available, 20% perf win.
  • Rework network device creation (in-kernel) API to more clearly identify network namespaces and their roles.
  • Use sysfs_break_active_protection() instead of trylock to avoid deadlocks between unregistering objects and sysfs access.
  • Add a new sysctl and sockopt for capping max retransmit timeout in TCP.
  • Support masking port and DSCP in routing rule matches.
  • Support dumping IPv4 multicast addresses with RTM_GETMULTICAST.
  • Support specifying at what time packet should be sent on AF_XDP sockets.
  • Expose TCP ULP diagnostic info (for TLS and MPTCP) to non-admin users.
  • Add Netlink YAML spec for WiFi (nl80211) and conntrack.
  • Introduce EXPORT_IPV6_MOD() and EXPORT_IPV6_MOD_GPL() for symbols which only need to be exported when IPv6 support is built as a module.
  • Age FDB entries based on Rx not Tx traffic in VxLAN, similar to normal bridging.
  • Allow users to specify source port range for GENEVE tunnels.
  • netconsole: allow attaching kernel release, CPU ID and task name to messages as metadata.

After updating to Linux 6.15, you will notice improved networking performance across many areas, alongside the new features that this pull request brings. The driver API has also seen interesting improvements, such as:

  • Continue rework / fixing of Energy Efficient Ethernet (EEE) across the SW layers. Delegate the responsibilities to phylink where possible. Improve its handling in phylib.
  • Support symmetric OR-XOR RSS hashing algorithm.
  • Support tracking and preserving IRQ affinity by NAPI itself.
  • Support loopback mode speed selection for interface selftests.

In addition to that, those improvements also bring support for new device drivers, improve existing device drivers, remove the IBM LCS driver for s390, and remove the sb1000 cable modem driver.

Making a few more short ethernet patch cables in, I hope, T568B style. The last time I had inadvertently and goofily focused on the T568A area in my cabling faq. And despite having done this for ages I don't have it memorized.

The T568A ones will and do work fine. But it's an annoying flub. I wonder what mistake I made this time ;)

Bonjour,

Besoin d'un conseil technique.
Je dois acheter un câble ethernet CAT7 de 30m
Sur les prix ça va de 15€ à 100 € du coup je suis un peu perdu, ça va servir à passer dans ma maison pour relier ma box à un répéteur wifi.
Des conseils ?
