After years of promises, real-time Linux is actually shipping. The mainstream take is that this is about lower latency, but the real story is deterministic scheduling for control systems that can't tolerate jitter. PREEMPT_RT removes the final excuse for proprietary RTOS holdouts, and that's a bigger deal than most realize. #kernel #realtime #embedded

Dirty Frag – kolejna metoda na root’a pod Linuxem
Pamiętacie Dirty Pipe? Łataliście ostatnio Copy Fail? Pasy zapięte? Nie? To niedobrze, bo kilka godzin temu pojawiła się nowa podatność określona mianem Dirty Frag. W ramce poniżej znajduje się tymczasowe rozwiązanie mające na celu wyłączenie niebezpiecznych modułów. Jest to luka klasy LPE (local privilege escalation), która pozwala na podniesienie uprawnień...

Have you run your Linux distribution updates recently? You probably should, because Dirty Frag and Copy Fail are coming for you.

I couldn’t find a list of #Linux #kernel versions that include a patch for #copyfail, so I dug into the commit log and made one. Make sure you’re using at least the following version of your branch to mitigate against copyfail:
- 7.0-rc7 (any stable 7.x is safe)
- 6.19.12
- 6.18.22
- 6.12.85
- 6.6.137
- 6.1.170
- 5.15.204
- 5.10.254
See https://copy.fail for more info about the #exploit.

IMHO #linux bisa seperti saat ini bukan karena diawali ingin menjadi sesuatu yang ideal tetapi justru karena pragmatisme.
Pd saat itu desain #microkernel #minix yg tdk monolithic dianggap sebagai mimpi indah idealisme sebuah #kernel. Tetapi Torvalds dan yang lain melihat banyak hal sangat ribet untuk diimpelmentasikan menggunakan desain microkernel, sehingga mereka memilih pragmatis.
Hingga lahir dan terus berkembanglah linux yang tidak ideal tapi bisa berevolusi menjadi seperti sekarang.
