Comment 3 Anthony Basile gentoo-dev 2015-10-22 01:20:46 UTC
i just tested 0.2.7.4_rc to the tree and tested and it worked.  can you try again at your end and see if something changed.
Comment 4 eroen 2015-12-23 22:19:22 UTC
I see this failure with net-misc/tor-0.2.7.6::gentoo, still only with USE=tor-hardening.
Comment 5 Anthony Basile gentoo-dev 2015-12-23 23:36:16 UTC
(In reply to eroen from comment #4)
> I see this failure with net-misc/tor-0.2.7.6::gentoo, still only with
> USE=tor-hardening.

Its due to your pax enabled kernel.  Please try the following test:

1. cd /var/tmp/portage/net-misc/tor-0.2.7.6/work/tor-0.2.7.6/src/test

2. If you are using PT_PAX then do

   paxctl -v test-bt-cl

and confirm that PAGEEXEC is *not* disable.  Alternatively if you are using XATTR_PAX then do

   paxctl-ng -v test-bt-cl

and similary confirm that PAGEEXEC is *not* disabled.

3. Run `./test-bt-cl assert` and confirm that you get a backtrace similar to the following:

Dec 23 18:33:53.015 [err] tor_assertion_failed_(): Bug: src/test/test_bt_cl.c:42: crash: Assertion 1 == 0 failed; aborting. (on Tor 0.2.7.6 )

4. Using either paxctl or paxctl-ng disable PAGEEXEC, like this:

# paxctl-ng -vp ./test-bt-cl 
./test-bt-cl:
	XATTR_PAX : p----


or similar for paxctl.

5. Run this again and see that you get a seg fault

# ./test-bt-cl assert
Segmentation fault


6. Check dmesg and see that the kernel trapped the seg fault:

[859936.458526] grsec: From 192.168.5.2: Segmentation fault occurred at            (nil) in /var/tmp/portage/net-misc/tor-0.2.7.6/work/tor-0.2.7.6/src/test/test-bt-cl[bash:12009] uid/euid:0/0 gid/egid:0/0, parent /bin/bash[bash:11966] uid/euid:0/0 gid/egid:0/0


This is due to intentionally evil code which a pax kernel disallows.  If you confirm the above, then this bug can be safely closed WONTIX.  Its a false negative which, quite frankly, I don't care to disable just for the sake of disabling it.  Its not indicating any problems with tor nor anything else.  Rather everything is working as intended.
Comment 6 Anthony Basile gentoo-dev 2015-12-28 19:13:26 UTC
Reopen this if my above analysis is incorrect.  We'll live with the test failure.
Comment 7 Paolo Pedroni 2016-01-18 10:58:00 UTC
I get this same error with a normal kernel (gentoo-sources-4.1.12, current stable). Would anyone care to reopen?
