EDIT 2018-02-21 05:01+00:00 s/ublocko/uBlock0/ and variants of it corrections. The copy/pasting now works verbatim for getting and on the tcp.stream.

It wouldn't work out of the box, it's a grsecurity-hardened kernel based system.

As usual these:

will need to be allowed more slack:

and doesn't fit in a post. But I wish so much to solve this issue, and if the need arises, I can post them somewhere on my NGO's website.

Maybe a few lines of it though:

But this is solved by making a compromise and allowing RWX mprotect of <anonymous mapping> by palemoon and plugin-container:

It will work now:

Code: Select all

mr@gdOv:~$ strace -tt -s128 -o ~mr/strace.d/palemoon_$(date +%y%m%d_%H%M%S)_O palemoon


Palemoon has opened a window. And it has already huge trace (mind that I've cared to take it quickly as the window showed up.

Code: Select all

And it's growing fast even on idle (doing nothing with it yet). And it already is too much for me to make anything out of it...

But Pale Moon works fine.

I had previously removed all the addons because I want to start anew.

I've browsed without a single crash all day yesterday, after these modifications.

And I felt I would first try and install Decentraleyes or uBlock origin addon which at first I didn't succeed because javascript.enabled in my about:config was at false (precaution in the wake of the spectre revelations, AMD64 here, meltdown no threat). Eventually, enabled javascript back, I successfully installed uBlock0... for a very short while.

uBlock0 addon appeared to be successfully installed for mere seconds only, and my Pale Moon within 10 sec after having reported that successful install of uBlock0 ,crashed.

I've tried a lot since then and from that later testing it appears that the uBlock0 install change has been causing the crashes of my Pale Moon. I just couldn't get it to work anymore until, that is, I removed uBlock0.
But it might make for a clearer narrative if I try and show what happened from the logs, and from decryptable traffic dump (which I hope I all have intact; even from the screencast if need be), given that I try and always run my (primitive) https://github.com/miroR/uncenz program for such purposes.

I've prepared the reduced, to-the-point trace with the SSL keys, and cast at:
Pale Moon and uBlock0 on a grsec-hardened kernel
https://www.croatiafidelis.hr/foss/cap/ ... n-uBlock0/

For quick insight, download just the:
dump_180220_0456_gdO_uBlock0.pcap
and
dump_180220_0456_gdO_uBlock0_SSLKEYLOGFILE.txt
download https://github.com/miroR/tshark-streams and run

Code: Select all

$ tshark-streams.sh -r dump_180220_0456_gdO_uBlock0.pcap -k dump_180220_0456_gdO_uBlock0_SSLKEYLOGFILE.txt -Y "tcp.stream==3"

That will get you (disregard the three other files):

Code: Select all

$ ls -l dump_180220_0456_gdO_uBlock0_s003-ssl.bin
-rw-r--r-- 1 mr mr 1773517 2018-02-20 12:43 dump_180220_0456_gdO_uBlock0_s003-ssl.bin

(Look up https://wireshark.org/wiki/SSL in case some kind less advanced reader is lost here.)
What istalled in my Pale Moon is what I downloaded, and what I downloaded is in that tcp.stream. If you run:

But what can clearly be seen in the screencast, is that my Pale Moon crashed right after installing uBlock0! Look it up, it's just 29 seconds, and if you check my PGP-signed hashes, and get the right hash, you're safe (not the case with Goog the Schmoogle videos, I don't think).

The video also serves to kind of verify the kern.log snippet that I'll post (I always have a

Code: Select all

# tail -f /var/log/kern.log

running for me):

But my (primitive) expertise ends here. Well, about what the PAX lines mean. I did, afterwards, sort that Pale Moon can write to /var/tmp (generally it sufficed to allow it the /tmp dir), but what those PAX numbers exactly mean, I don't currently know.

I have grsecurity RBAC deployed (Role Base Access Policy, if anyone not familiar, find it on forums.grsecurity.net pls.

But I start investigate now what this could be, without enabling RBAC, thought still with simply grsecurity kernel (I generally don't go online with Mr. Linus' plain non-hardened kernel --although they've recently copied a lot of code from grsecurity's original kernel patch, in the wake of Meltdown and Spectre computing disaster: the problem is Schmoogle the Goog controls now Linux security, and I don't trust unofficial world top spy agencies like the Schmoog to care for my security).

Again, in this post I only showed verifiably what I had (previously, very early in the morning CET) downloaded and installed (the uBlock0) in my Pale Moon when it crashed the first time after I compiled it and installed it, and how it crashed.

In the next post, I'll try reinstalling it, and try and analyze what happens (wrong).

Re: Installing uBlock Origin breaks Pale Moon on grsec-hardened kernel

Unread postby miroR » Tue, 20 Feb 2018, 20:59

At this stage, I have Pale Moon:

Code: Select all

$ palemoon --version
Moonchild Productions Pale Moon 27.7.2

installed, running fine. It has no addons, no extensions, nothing whatsoever. Vanilla Pale Moon. There are no issues.

Code: Select all

Feb 20 14:11:13 gdOv kernel: [273064.456096] grsec: (root:U:/sbin/gradm) exec of /sbin/gradm (gradm -D ) by /sbin/gradm[bash:23619] uid/euid:0/0 gid/egid:0/0, parent /bin/bash[bash:3813] uid/euid:0/0 gid/egid:0/0

One potential actor out of sight, the grsec RBAC is disabled, for these new tries to install addons.

But it's first actually just enabling uBlock0, because I see it grayed out in about:addons:

Code: Select all


UO uBlock Origin 1.15.6 (disabled)                                         +--------+  +--------+
   Finally, an efficient blocker. Easy on CPU and memory. [u]More[/u]      | Enable |  | Remove |
                                                                           +--------+  +--------+

I'll try and simply just click on "Enable". I'll trace it with strace, then enable it.

As in the first post:

Code: Select all

$ strace -tt -s128 -o ~mr/strace.d/palemoon_$(date +%y%m%d_%H%M%S)_O palemoon


So starts running fine. The trace is already 3M, just starting it, and writing the above:

Code: Select all

mr@gdOv:~$ ls -l strace.d/palemoon_180220_142155_O  strace.d/palemoon_180220_142155_O_1
-rw-r--r-- 1 mr mr 3210517 2018-02-20 14:23 strace.d/palemoon_180220_142155_O
-rw-r--r-- 1 mr mr 3207367 2018-02-20 14:23 strace.d/palemoon_180220_142155_O_1
mr@gdOv:~$

Going to about:addons and Enabling as I said.

Little happened so far... Oh now, it did happen right after I thought it wouldn't happen so soon. Here's the current log snippet:

And, according to my understanding, the "execution attempt in: (null)" (whatever exactly that it mean) happened after I had already cp'ed the main trace filename to the palemoon_180220_142155_O_1. So only the last 5M of text are key to examine (I'm joking of course, it's all system calls, signals, and symbols, not complete mumbo-jumbo but rather vague to me... Very hard work).
(
Because:

Code: Select all

mr@gdOv:~$ cp -iav strace.d/palemoon_180220_142155_O  strace.d/palemoon_180220_142155_O_1
cp: overwrite 'strace.d/palemoon_180220_142155_O_1'? ^[[A^C
mr@gdOv:~$ cp -iav strace.d/palemoon_180220_142155_O  strace.d/palemoon_180220_142155_O_2
'strace.d/palemoon_180220_142155_O' -> 'strace.d/palemoon_180220_142155_O_2'
mr@gdOv:~$

I didn't overwrite palemoon_180220_142155_O_1 which I copied the palemoon_180220_142155_O to previously.
)

And my very tentative guess about what happened follows, some three hours of perusing the strace output
(
which is available, somewhat anonymized, such as the salt is redacted at:
Pale Moon and uBlock0 on a grsec-hardened kernel 2
https://www.croatiafidelis.hr/foss/cap/ ... ock0-2.php
).

It's PAX/grsec not allowing uBlock0 for some reason and in some way.

All is (likely) still well up unto my clicking of the uBlock0 extenstion's:

...with the same "Resource temporarily unavailable".

We reach to really huge stretches of almost uniform:

Code: Select all

14:24:21.569021 madvise(0x38202416000, 24576, MADV_DONTNEED) = 0
[...some 1047 lines cut here, all but one with "madvise", only different timestamps...]
14:24:21.766990 madvise(0x381ff081000, 4096, MADV_DONTNEED) = 0

And 0.2 seconds is a very long time for processes.

Interestingly no more openat system calls to be found after that stretch of madvise.

Instead, one last stretch of a similarly boring:

Code: Select all

14:24:24.132622 gettimeofday({tv_sec=1519136664, tv_usec=132686}, NULL) = 0
[...16798 lines cut here all but a very rare few of same content, but different timestamps...]
14:24:28.636786 gettimeofday({tv_sec=1519136668, tv_usec=636849}, NULL) = 0

The very few interruptions look like this:

Code: Select all

14:24:28.640477 mmap(NULL, 1048576, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x381f1b00000
14:24:28.642535 futex(0x382193b3bb4, FUTEX_WAKE_PRIVATE, 1) = 1
14:24:28.640477 mmap(NULL, 1048576, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x381f1b00000

Code: Select all

14:24:28.654944 gettimeofday({tv_sec=1519136668, tv_usec=655299}, NULL) = 0
[...2480 lines cut here all but a very rare few, if any, of same content, but different timestamps...]
14:24:29.385217 gettimeofday({tv_sec=1519136669, tv_usec=385290}, NULL) = 0

And then it all ends abruptly with this, argh, liberating line:

Code: Select all

Re: Installing uBlock Origin breaks Pale Moon on grsec-hardened kernel

Unread postby miroR » Tue, 20 Feb 2018, 21:28

Indeed I have no issues (pls. read me corrected in [2]) with vanilla Pale Moon in my grsec-hardened Linux... well, it's actually grsecunoff (grsec-unofficial, but that's little else than semantics and... aarghh... quality, the difference; there are not so often geniuses born like spender and PaX Team... Also Windows had, at one time benefited, if I'm allowed the short digression[1]).

But on those heavy advertizing heavy intrusion into your privacy very loaded locations, not on Pale Moon forums, or Devuan forums or Debian forums... well not so far... (And I'm posting this with my updated Pale Moon 2.7.7.2.)

That's it, I posted all I could to try and reach for a solution, and get me the good addons and extensions, that I was advised months ago in:
Tracking protection and NSS SSL secrets logging (two security questions)?

Thanks if anybody has a piece of advice!

[2] The first issue I just had when, after opening my old:
Grsecurity/Pax installation on Debian GNU/Linux
http://forums.debian.net/viewtopic.php?f=16&t=108616
to find the links in the [1], and when I went to check that those links weren't dead (they are not at this time), the Schmoog attacked me (joking, pls. don't get that too seriously... but there was a lot of google in the traffic dump :) )
(and when I opened those links from [1] above] I got a:

Code: Select all

with nothing in the logs... Cruel world out there...

Re: Installing uBlock Origin breaks Pale Moon on grsec-hardened kernel

Unread postby miroR » Thu, 22 Feb 2018, 19:38

Some people apparently think this issue is not to blame on grsec (both, but the first only if I read him correctly):
https://github.com/gorhill/uBlock/issue ... -367143816
and
https://github.com/minipli/linux-unoffi ... -367473590

My Pale Moon that I gave links to how I compiled it in top of the first post, has devtools. I haven't really used those previously.
Can anybody give a few quick tips where to go to (more quickly) try to learn how to use debugger, or console --or if I should use some other tool-- to try and find out more about what is causing these crashes in my Pale Moon?

I've read a few guides:
https://developer.mozilla.org/en-US/doc ... er/UI_Tour
https://mozilladevelopers.github.io/pla ... /debugger/
but I'd like something that I could apply more quickly to this particular case that I have, these crashes upon installing of uBlock0.

Thanks in anybody has a few quick tips.

Gosh! Miro-Biro is so slow... Took me so long... Argh...
But I think this is solved. I'll mark it as solve once I completely confirm that my Pale Moon is working correctly regading this uBlock0 issue.

In short, the more upstream devs are right. I've, properly installed (apparently) Pale Moon 2.7.7.2, and here's what needs to be used, of compilers in Linux:
about:buildconfig

Code: Select all

Build tools
Compiler    Version    Compiler flags
gcc-4.9    4.9.2    -Wall -Wdeclaration-after-statement -Wempty-body -Wpointer-to-int-cast -Wsign-compare -Wtype-limits -Wno-unused -Wcast-align -g -O2 -std=gnu99 -fgnu89-inline -fno-strict-aliasing -ffunction-sections -fdata-sections -fno-math-errno -pthread -pipe
g++-4.9    4.9.2    -Wall -Wempty-body -Woverloaded-virtual -Wsign-compare -Wwrite-strings -Wno-invalid-offsetof -Wcast-align -g -O2 -fno-exceptions -fno-strict-aliasing -fno-rtti -ffunction-sections -fdata-sections -fno-exceptions -fno-math-errno -std=gnu++0x -pthread -pipe -DNDEBUG -DTRIMMED -g -freorder-blocks -O2 -fomit-frame-pointer

Some more testing, so I can (hopefully) declare this issue solved. Be back.

This issue is SOLVED.
(However forum rules do not make possible editing a few days old posts, which is fine, only I can't mark the title with SOLVED)
