The keystore password on Java keystore files is utterly pointless. You can reset it without knowing it, as shown by this code. Note that private keys are still secure, as far as I know. The JKS implementation is copyright Casey Marshall (rsdio@metastatic.org), and the original source is available at http://metastatic.org/source/JKS.java. I've in…

Intel Corporation Wireless 7260 on Mageia 5 (but with kernel-tmb-laptop)

After updating from Mageia 4 to 5, the builtin wireless on my Lenovo T440s stopped working. When attempting to configure the card via the network center or drakconnect, I would get the message "Unable to find network interface for selected device (using iwlwifi driver)". Removing and re-adding the iwlwifi module via modprobe did nothing. The wireless card was definitely available according to lspci. I had the iwlwifi-agn-ucode package installed. ls /lib/firmare listed several ucode files for iwlwifi-7260.

Some investigation found Mageia 5 does not provide a kernel-tmb-laptop package, which means I was still running on 3.14.43-tmb-laptop-1.mga4. Changing the kernel just to go from 3.14 to 3.19 but perhaps lose laptop features didn't seem worth it.

To get the wireless working again, I just needed to go to https://wireless.wiki.kernel.org/en/users/Drivers/iwlwifi download the correct ucode file (iwlwifi-7260-ucode-25.228.9.0.tgz) which contains iwlwifi-7260-9.ucode. Copy to /lib/firmare, rest
