I was thinking I should post my tiny investigation into a small jacksum java program apparent misbehavior, as it is a textbook example of the goodness of grsecurity's logging, even though I only later in my thinking, and still without certainty, changed the direction of where to search for solution on this issue (and finally solved it in unpredictable way, for me).
( see below why java-config, near the 'equery b' string )
And yet:
In the logs:
And there is where the trouble is starting:
In the logs that expands to:
But that is the same as further above. Already seen.
Is it youtube-dl? Because the othe two packages have been around for months and: no issues...
It appears to be in constant development though:
(and I could probably look further back in my archives if need be)
My new entries in package.mask:
emerge -tuDN youtube-dl
...
But to no avail. Same error, same lines in the logs.
Next I try:

And, more tries... As root:
Working!
What is the matter here?
It did the work. I just (was quite a bunch in that directory to calculate) got out:
Just to have more complete insight, here are the corresponding lines in the syslog:
And jacksum did the work. As admin, though. So it may be a grsecurity's GRADM permissions issue.
As admin. And this issue has popped up only after yesterday's update of my Gentoo ~amd64 system.
A permission issue? But I can't do much about it with the upstream really, other than seek advice from be it advanced grsecurity users who read this or further above. Because...
Because, in my testing (~amd64) Gentoo, the hardened kernel sources:
are regularly updated;
and I have these installed:
, but the gradm utility:
is not. And I suspect that maybe I should try and install a more up-to-date testing (free) gradm, first.
And also, if that is the case, since the Gentoo maintainers had explicitly asked for feedback on grsec-hardened (when it went stable-is-non-free)... [also] do provide some feedback to them...
That could be a lot of work (a lot of other work of mine to leave waiting in the queue for longer).
However, I don't believe to be safe online without a properly hardened system. To go the NSA Linux (oh I meant the SELinux) way maybe? Like somewhere I listened to even Linus recommending? Ts, ts!
I'll see what I can do to present this case, and if I can try and get a bug presented to Gentoo Hardened team, for simply the gradm utility left without maintainers' "love"...
Bugs a getting galore in Gentoo, just to present a more complete picture. Close to 100 opened (one is mine), I read just yesterday on the gentoo-dev... And there're other issues with Gentoo, too much outside the scope of this topic to tell about them.
Another post, else it'll be too unreadable.

And jacksum did the work. As admin, though. So it may be a grsecurity's GRADM permissions issue.
As admin. And this issue has popped up only after yesterday's update of my Gentoo ~amd64 system.
A permission issue? But I can't do much about it with the upstream really, other than seek advice from be it advanced grsecurity users who read this or further above. Because...
Because, in my testing (~amd64) Gentoo, the hardened kernel sources:
- Code: Select all
# ls -l /usr/portage/sys-kernel/hardened-sources/ | grep hardened
-rw-r--r-- 1 portage portage 1273 2016-02-20 08:51 hardened-sources-4.3.3-r4.ebuild
-rw-r--r-- 1 portage portage 1273 2016-02-28 20:39 hardened-sources-4.4.2.ebuild
-rw-r--r-- 1 portage portage 1273 2016-04-30 19:51 hardened-sources-4.4.8-r1.ebuild
-rw-r--r-- 1 portage portage 1275 2016-06-28 13:39 hardened-sources-4.5.7-r5.ebuild
-rw-r--r-- 1 portage portage 1275 2016-07-12 21:10 hardened-sources-4.6.4.ebuild
#
are regularly updated;
and I have these installed:
- Code: Select all
# equery l hardened-sources
* Searching for hardened-sources ...
[I--] [??] sys-kernel/hardened-sources-4.5.7-r3:4.5.7-r3
[I--] [??] sys-kernel/hardened-sources-4.5.7-r7:4.5.7-r7
[IP-] [ ] sys-kernel/hardened-sources-4.6.4:4.6.4
#
, but the gradm utility:
- Code: Select all
# ls -l /usr/portage/sys-apps/gradm/ | grep gradm
-rw-r--r-- 1 portage portage 1081 2016-03-16 07:50 gradm-3.1.201507191652.ebuild
-rw-r--r-- 1 portage portage 1094 2016-05-26 10:17 gradm-3.1.201603152148.ebuild
#
is not. And I suspect that maybe I should try and install a more up-to-date testing (free) gradm, first.
And also, if that is the case, since the Gentoo maintainers had explicitly asked for feedback on grsec-hardened (when it went stable-is-non-free)... [also] do provide some feedback to them...
That could be a lot of work (a lot of other work of mine to leave waiting in the queue for longer).
However, I don't believe to be safe online without a properly hardened system. To go the NSA Linux (oh I meant the SELinux) way maybe? Like somewhere I listened to even Linus recommending? Ts, ts!
I'll see what I can do to present this case, and if I can try and get a bug presented to Gentoo Hardened team, for simply the gradm utility left without maintainers' "love"...
Bugs a getting galore in Gentoo, just to present a more complete picture. Close to 100 opened (one is mine), I read just yesterday on the gentoo-dev... And there're other issues with Gentoo, too much outside the scope of this topic to tell about them.
Another post, else it'll be too unreadable.
