[arch-general] providing grsecurity in [community]
by henning mueller 18 Apr '14

18 Apr '14

Hey, I'm replying to a thread on arch-dev-public with the same subject, here. I'm maintaining the linux-grsec PKGBUILD in the AUR [0], wrote an utility to set PaX flags [1] and host a repository for binary grsecurity packages [2]. Although I like the idea of further integrating grsecurity into Arch Linux, I have some points to criticize on the planning proposals of Daniel Micay. > It also includes the PaX project to provide a much stronger > implementation of ASLR along with significant memory protections > for userspace. These features do break many packages, and require > setting flags on binaries when exceptions are necessary. I don't > want to place a burden on other packagers, so I plan on leaving > the parts requiring integration with other packages disabled at > first. 1. The very core of the grsecurity project is PaX. Without it, you miss out on the most effective security features. Some contributing linux-grsec users and me collected numerous binaries, which do not work well with PaX and the according PaX features, which have to be disabled in order to get them running. These are currently collected in the linux-pax-flags utility [1]. For a clean grsecurity integration, any flags on [core], [extra] and [community] should be set before releasing linux-grsec in [community]. > It would have no impact on people not using it, since it would > just be a very short string set in the `user.pax.flags` xattr key. > For example, `setfattr -n user.pax.flags -v "mr" > "$pkgdir/usr/bin/foo"` to disable MPROTECT and RANDMMAP features > (on chromium, firefox, etc.). 2. I think, manually setting the flags with a setfattr call in the PKGBUILDs is a bad solution, because it is error-prone. The Gentoo (hardened) folks integrated a new function for marking binaries with PaX flags into the ebuild environment. I would prefer a solution like this for Arch, too. A new PKGBUILD variable for PaX flags to be set after install() would also be a good solution (like PAX_FLAGS=(usr/bin/firefox:mr). (There is also a utility which supports xattr flags by the Gentoo hardened folks named paxctl-ng.) 3. I do not know, what the policy is, here, but I would prefer to maintain the PKGBUILD myself, if it gets included in [community]. At least, I would have expected to be integrated in the discussion a little more. I did the work on it since beginning of 2012 and run it on several machines since then. I think, a message like "I will adopt your package in [community]" is a little rude. The gradm package was already deleted from the AUR. On the linux-pax-flags AUR package, Daniel commented that I would have to change it to work according to his plans. I want to mention another step, that would be necessary for a decent integration of grsecurity and full ASLR: The activation of PIE/PIC. This has been discussed a little on the Arch Linux BBS [3]. Allan stated that "If there is a good way to add it for x86_64, it will be considered." Maybe it is possible to come up with a good way.

[arch-general] system-config-printer: conflicting files
by Kyle Terrien 18 Apr '14

18 Apr '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello fellow Archers, I received the following error while upgrading system-config-printer: > error: failed to commit transaction (conflicting files) > system-config-printer: /usr/share/system-config-printer/debug.pyc > exists in filesystem Errors occurred, no packages were upgraded. Apparently, at some point python automatically compiled debug.py into debug.pyc to increase long term performance. However, the new package has debug.pyc presupplied. The solution was to delete debug.pyc, then everything installs cleanly and works fine. Of course, this begs the question: Should a compiled python module be supplied in a package (debug.pyc), or should the local machine interpret/compile/do whatever it wants with a python script (debug.py)? - --Kyle -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBAgAGBQJTUH7GAAoJEN5rMzXPJBsQvwkP/jrjwgfai7jUTTFI980qQdaM nu6u/kms6Ys72uJIvxF3a0b94ZprbLe6bjshzCBW0fJuBHrZ+Deb1Xdt2i10b3pV O/JgZzYMsICVqF2MYdn+GZ9T/GYkLpzLWctwBCnHwQKABIw+T5Jk4CwdNLTnd4V5 pmxynMi/A3RzYFsxFQLcNK6a1sk/FhVmwDSAk5WB2feKjf/i614dH8Uf0aJxRcq+ LFg+eFndpEpMp77j0DnxcTwAR6RzdE19NCNf9rfBvctGpyE2nzdYE8bcof66mLoB yWR2jmRC2CYwOxU556I+Bg4TIGy4SQunqkc0hKEG+nQ6/xSOV72CF7ZCFBOKrLsW 8rGPHDNXFFbLeE6kcR+hnEYaKjLTLn+o+BwV9CJSB3l3aCXpoBCJ9kDiEPEfPR6h mZwP77BpBUMTfclTYL/F2mR0NDd4615CWxXd6wHXGCex+WrA4FTyGqGQgUvPa5Bu 9yB/oMyLthgGL9S5CN0N2VcRdPQB4X44DhUieOMqWAO+KVKmJGfohkCRRHy7UOCY JLh8dkA9JBnoeQ9wLFXn7ibSFxJAVfUeddnmsKOaRnVSGVjGuKYbb9IcFQ/xcfBa ghnTIOk6l15Rrzd9pxfoXSDz8eIeC9UWGQN13Q6waD1gOjZVPS2rgmM2vNpYzT5M iyOEOWaj6AVvni9eADE1 =tWUo -----END PGP SIGNATURE-----

[arch-general] Problem with Wifi Connections (Intel Corporation PRO/Wireless 4965 AG Connection)
by Sean Snell 17 Apr '14

17 Apr '14

Hi everybody, First, this is on a Lenovo X61 laptop. This is a fresh installation on a new SSD hard drive I recently purchased. I already have a 500GB hard drive with Arch and Windows dual booting on it, and the Wifi still works just fine from the old installation when I reinstalled the old hard drive for testing, but for the life of me I cannot get wifi-menu to connect to any wifi connections on this new installation. The card is a Intel Corporation PRO/Wireless 4965 AG. Per the wireless wiki<https://wiki.archlinux.org/index.php/Wireless_network_configuration#iwlegacy>, I've installed linux-firmware so I can use the iwlegacy (driver?). With the help of a friend, we feel the modules are loading correctly, but when we try to actually connect using wifi-menu, journalctl -xn says the following: \\\\\\\\\\\ - Unit netctl(a)wls3\x2dNEOPCS\x2dSecured.service has begun starting up. Starting network profile 'wls3-NEOPCS-Secured'... The interface of network profile 'wls3-NEOPCS-Secured' is already up netctl(a)wls3\x2dNEOPCS\x2dSecured.service: main process exited, code=exited, status=1/FAILURE \\\\\\\\\\\\\ What I've installed in relation to the Wifi: - wpa_supplicant (per the initial insistence of wifi-menu "out of the box" - linux-firmware (per the wiki<https://wiki.archlinux.org/index.php/Wireless_network_configuration#iwlegacy> ) Output of lspci | grep "Intel": 00:00.0 Host bridge: Intel Corporation Mobile PM965/GM965/GL960 Memory Controller Hub (rev 0c) 00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (primary) (rev 0c) 00:02.1 Display controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (secondary) (rev 0c) 00:19.0 Ethernet controller: Intel Corporation 82566MM Gigabit Network Connection (rev 03) 00:1a.0 USB controller: Intel Corporation 82801H (ICH8 Family) USB UHCI Controller #4 (rev 03) 00:1a.1 USB controller: Intel Corporation 82801H (ICH8 Family) USB UHCI Controller #5 (rev 03) 00:1a.7 USB controller: Intel Corporation 82801H (ICH8 Family) USB2 EHCI Controller #2 (rev 03) 00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03) 00:1c.0 PCI bridge: Intel Corporation 82801H (ICH8 Family) PCI Express Port 1 (rev 03) 00:1c.1 PCI bridge: Intel Corporation 82801H (ICH8 Family) PCI Express Port 2 (rev 03) 00:1d.0 USB controller: Intel Corporation 82801H (ICH8 Family) USB UHCI Controller #1 (rev 03) 00:1d.1 USB controller: Intel Corporation 82801H (ICH8 Family) USB UHCI Controller #2 (rev 03) 00:1d.7 USB controller: Intel Corporation 82801H (ICH8 Family) USB2 EHCI Controller #1 (rev 03) 00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev f3) 00:1f.0 ISA bridge: Intel Corporation 82801HEM (ICH8M-E) LPC Interface Controller (rev 03) 00:1f.2 IDE interface: Intel Corporation 82801HM/HEM (ICH8M/ICH8M-E) SATA Controller [IDE mode] (rev 03) 00:1f.3 SMBus: Intel Corporation 82801H (ICH8 Family) SMBus Controller (rev 03) 03:00.0 Network controller: Intel Corporation PRO/Wireless 4965 AG or AGN [Kedron] Network Connection (rev 61) Output of lsmod | grep -h "iw": iwl4965 90075 0 iwlegacy 49001 1 iwl4965 mac80211 490609 2 iwl4965,iwlegacy cfg80211 431038 3 iwl4965,iwlegacy,mac80211 led_class 3547 3 sdhci,iwlegacy,thinkpad_acpi Can anybody help clue me into what I might be overlooking?

[arch-general] bumblebee: only working every other time
by Magnus Therning 16 Apr '14

16 Apr '14

I've finally gotten around to installing and configuring bumblebee. It's working, sort of. It's rather weird because it only works every other time: ~~~~ % cat /proc/acpi/bbswitch 0000:01:00.0 OFF % primusrun glxspheres64 primus: fatal: Bumblebee daemon reported: error: [XORG] (EE) NVIDIA(GPU-0): Failed to initialize the NVIDIA GPU at PCI:1:0:0.

The next run of `primusrun` fails, usually with the message ~~~~ % primusrun glxspheres64 primus: fatal: Bumblebee daemon reported: error: [XORG] (EE) Server terminated successfully (0). Closing log file. ~~~~ the next run works. And so on. Very strange behaviour I think. And the $SEARCH_ENGINE doesn't really offer any help either, most people seem to have the problem that it never works, not that it works 50% of the times :( Any and all help much appreciated. /M -- Magnus Therning OpenPGP: 0xAB4DFBA4 email: magnus(a)therning.org jabber: magnus(a)therning.org twitter: magthe http://therning.org/magnus Most software today is very much like an Egyptian pyramid with millions of bricks piled on top of each other, with no structural integrity, but just done by brute force and thousands of slaves. -- Alan Kay

[arch-general] Evolution
by Ralf Mardorf 16 Apr '14

16 Apr '14

Hi, here Evolution 3.12.1 has so many bugs, that I won't write tons of bug reports, but ask you to provide Evolution 3.10.4 by the Arch repository again. I Cc to upstream, since it's not the first time that upstream released a version that is completely unusable for _serious_ work. Regards, Ralf

[arch-general] Gedit
by Ralf Mardorf 15 Apr '14

15 Apr '14

Hi, do I miss options for the preferences or doesn't gedit provide a menu bar and window buttons anymore? A menu bar might be something to argue, since it's part of the app, but the window buttons are provided by the window manager I decided to use. Will this happen to other editors, such as pluma and other apps too? Disgusting! Doers it make sense to send a veto to upstream or is it wanted by most users? Regards, Ralf

[arch-general] Bluetooth keyword layout in Gnome 3.12
by Mikhail Strizhov 15 Apr '14

15 Apr '14

After Gnome 3.10 -> 3.12 upgrade my Bluetooth keyboard layout became crazy. There are no English letters, instead it types some numbers. Sounds silly, but if I press in gedit letter "p" is prints "*", "o" is "6", "l" is "3", "q", "w" and others do out output anything. The keyboard is visible in Bluetooth settings. I also tried to delete the keyword settings and reconnect it and it was successful, layout is still incorrect. Any ideas?

Hi Everyone, I am not sure which part of this particular combination is broken, but after an update today I was unable to use my NVIDIA GPU. Reverting back to an older version of the kernel and the relevant driver packages fixed the issue. I have created the following bug report. https://bugs.archlinux.org/task/39848 Has anyone seen a similar problem ? -- Pavan
