… HP with very buggy firmware. Only legacy boots on MBR work.

Which model?

 

[Alain De Vos]

HP Pavillion.
To upgrade the firmware your computer must run windows.
And I must replace the video card to the original, upgrade the firmare, and replace the new video card back.
The firmware cannot boot an O.S. from GPT. Only from MBR.
For legacy boot the firmware thinks you only run Windows ... and it gets confused.
Except the firmware it is a good PC. 8-Core and silent.

For linux, this can be fixed with the boot arguments acpi_os_name= and/or acpi_osi=, I'm not sure the equivalent for FreeBSD.

So why don't you use MBR as the Partition Scheme?

I've been doing so since FreeBSD 12.0-RELEASE (or somewhere thereabout) had problems booting from GPT:

At the Partitioning menu choose Auto (UFS) Guided Disk Setup, for simplicity, and MBR for the Partition Scheme. It will give you a choice of where to install, choose your HDD which will be designated as ada0. There have been problems reported with this stage of installation and I changed from GPT to MBR to get past a sticking point.

I have to use MBR as scheme on my first primary boot disk. For the others i can use GPT with an unlimited number of partitions.

Falkon

… eating 2.5G resident memory & CPU idle time,

No problem here (with YouTube, https://www.youtube.com/watch?v=NlDCPCwVNUw for example):

Web

I get playback, but there's associated hogging of the kernel. Alain, if you find the same you might like to report a bug.

Still hogging during playback of YouTube content. A trough after quitting:

I don't have youtube issues with firefox. No memory/cpu hogging and no delays when playing. This is in virtualbox

 

[Cath O'Deray]

I don't have youtube issues with firefox.

The same here, Firefox is fine.

Web

I meant Web a.k.a. www/epiphany as originally pictured, <https://forums.freebsd.org/goto/post?id=518126>

Firefox still has the aslr bug ,

kern.elf64.aslr.stack_gap=0

 

[Aeterna]

Firefox still has the aslr bug ,

kern.elf64.aslr.stack_gap=0

maybe, but it seems that as of now you have two options, usable browser everywhere (firefox) but no aslr, or aslr and not very usable browser.

 

[Alain De Vos]

That's why chromium browser is currently compiling for at least 24h.

 

[Deleted member 30996]

If it's a browser based exploit doesn't it need JS enabled to work?

 

[dacrackerx64]

Firefox still has the aslr bug ,

kern.elf64.aslr.stack_gap=0

I worked around this issue by disabling aslr only
for Firefox and Thunderbird as such:
elfctl -e +aslr /usr/local/bin/firefox

 

[Deleted member 30996]

Firefox still has the aslr bug ,

Could you please show me, maybe in the Security for Security's Sake thread, where that is a current Firefox bug, and that it can't be mitigated by disabling JavaScript?

 

[Alain De Vos]

I have nothing to show. I just poke. Once maybe i come back.

 

[Vull]

Firefox still has the aslr bug ,

kern.elf64.aslr.stack_gap=0

Link please.

Edited to add: I don't enable ASLR in any case.

This is my T61 with 15.4" 1680x1050 (WSXGA+) widescreen and Intel Core2 Duo T7300 @ 2.00GHz with 4GB RAM and Scorpio Black 250GB HDD @ 7200RPM running FreeBSD 12.2-RELEASE-p7 featuring Maiya Maa Kali - Goddess of Death, Time and Doomsday.

I'm thinking of repurposing it as my .mp3 player and bringing my other W520 online, since it's more powerful and this has a really nice picture if I happen to watch movies.

with intel cpu and tsx, kasrl is broken
https://dl.acm.org/doi/10.1145/2976749.2978321
Maybe there are mitigations, but since intel decided to completely disable tsx (starting with the latest cpus), these mitigations may not be very efficient.

My workaround is simply meant to run Firefox/Thunderbird with ASLR enabled for all other applications. It works
in the sense that Firefox/Thunderbird runs.

Guess who I'm going to submit these Kali wallpapers to...
