[gentoo-user] How do I restore special keys in X?
We've all heard about the DontZap fiasco, caused by a few whiners. I managed to restore that, but there seems to be even more lost functionality. MagicSysReq no longer works in X. In addition, I've made a slight change in /etc/inittab... ca:12345:ctrlaltdel:/usr/bin/chvt 1 ...which should cause ctrl_alt_del to kick me into tty1, rather than rebooting. Here is the InputDevice section in my xorg.conf which (along with DontZap) restores ctral_alt_bksp functionality. Section InputDevice Identifier Keyboard0 Driver kbd Option XkbOptions terminate:ctrl_alt_bksp Option XkbOptions terminate:ctrl_alt_del EndSection MagicSysReq and the modified ctrl_alt_del both work from a text console, but not from X. What do I have to do to enable them? BTW, I am not running HAL or DBUS. -- Walter Dnes waltd...@waltdnes.org

The only choice you have is to rebuild the whole package using emerge -- oneshot package. By the way, the rebuild will also pull the new dependencies implied by the new use flags settings. OT for the original question, but there is a way to lessen the amount of work done if a package may need to be merged (or attempted to be merged) repeatedly. You have to do it manually though: - ensure all needed deps are already installed - ebuild package command where command is on of fetch, unpack, compile, install, etc as detailed in the ebuild man page. You can't restart a failed compile from where it left off [you can do that if you are running make manually, but ebuild abstracts that away] but at least some work can be omitted. If course, this in no way answers the original question, but it's occasionally useful to know -- alan dot mckinnon at gmail dot com

[gentoo-user] skip some package in glsa-check
hi, I run glsa-check -f affected to update a Gentoo system, but there's one specific package I can't update, because it's a C library someone is using and the 'secure' version is causing segmentation fault on her program, so I added it to packages.mask. but as I run glsa-check in a cron job, if there's one package it can't emerge, it won't emerge the rest of them (if only I could add --keep-going). does anyone have a solution to this? I want to keep running glsa-check to update my system, but I don't want to update one specific package. thanks! -- Crístian Deives dos Santos Viana [aka CD1] Sent from Campinas, SP, Brazil

[gentoo-user] gmonstart / jvregisterclasses in tons of binaries with commands,malware?
In linux binaries, in any linux distro, I've discovered the same strings which I believe may be due to a virus or trojan. Yet, clamav, rkhunter, chkrootkit do not detect abnormalities. Whether I run 'strings' on the binary files or view with vim or gedit, here is what is always seen inside the binaries: __gmon_start__ _Jv_RegisterClasses Followed by commands which differ within each binary. If, by some luck, I've downloaded a fresh Linux ISO where binaries do not include the above two strings followed by commands, after I run an update the updated binaries suddenly contain the above two strings and other, what I believe to be, rogue strings. I've avoided the possible infection with an OpenBSD install, yet all the Linux installations and burned ISOs contain binaries with the above two strings followed by commands. Search using find within your bin and sbin directories for those two strings and see how many positives you find. Now use a text editor like vi or gedit and search through the gibberish, locate these strings and isolate the commands, if any, which follow them. Searching for gmonstart, gmon, registerclasses, jv, etc. variations of works. If you find results in your binaries, please copy/paste the commands following the gmonstart and jvregisterclasses strings so I may compare them to mine. I've purchased Linux CDs from brick + mortar stores, downloaded ISOs from different physical locations and found some CDs contained these strings in the binaries and one or two rare ones did not, but when installed/updated on a network connection the binaries replaced in the update process would show these strings!! These strings are not alone by themselves in the binaries they follow with commands with a @ mark before each command. Google results are vague, some suggest shell backdoors, every Linux user I've asked to date calls me paranoid while at the same time this knowledge comes as a surprise to them, too, when they search their binaries and find the same strings. I'm amazed by how quickly some rush to judgement and call you a paranoid for being curious about the files on your system. The strings may/may not be common, but in comparing commands which follow these strings I've noticed some which seem down right malicious! Maybe they're right, I'm just paranoid, but what am I seeing and why are these strings so common across Linux distros binaries, esp. the Jv (java?) reference? Please, any help?

[gentoo-user] Broken upgrade from udev troubles.
I spent the day recovering from a Gentoo upgrade, and thought I'd document the experience in case it helps someone else. I'm running a custom kernel 2.6.25-gentoo-r7 on amd64, though I don't think the rarer hardware is relevant. I tend to put off upgrading my Gentoo box because anytime I do, something breaks. I'm afraid I haven't changed my opinion about that. Anyway, I did emerge --update --deep world and plugged my ears. Some 600-odd packages (and a few simpler problems) later, the system seemed to be doing okay. So I thought I'd see if it could survive a reboot. No, it couldn't. On boot it failed checking the root file system and dropped into the repair shell. The reason the fsck failed is that the root pseudo device file /dev/md0, didn't exist. The root file system was actually, fine, though. Inside the repair shell, I could see all the files from my root, but there wasn't much in /dev. (I have the md stuff compiled in to the kernel, and don't use an initrd, so it wasn't an initrd problem.) *Short Solution *The problem was with udev, the facility which automatically populates the /dev directory. During the upgrade, emerge noted that my kernel version was a bit early, but acceptable. What was missing, apparently, was the signalfd syscall, which that kernel version either doesn't have or I hadn't configured. Apparently, udev has only started using signalfd recently, so the solution was to downgrade to an older version of udev (udev-141 to be precise). *What I Actually Did To Get There* Of course, I didn't know that at first. Just had a fun unbootable system. I might have been able to simply emerge the downgrade from the repair shell (the network did come up), but I didn't know to try that yet. I figured I wanted to find some way to make the system boot. Since the failing file check is done from /etc/init.d/checkroot, I added a mknod command to create the device node before trying to run the file check. At the start of the start() method: if [ ! -e /dev/md0 ] ; then mknod -m 0660 /dev/md0 b 9 0 fi It's a hack, not a solution, but it did make the system boot, to a rather crippled state. Since there were a lot of devices missing, a lot of services wouldn't start. (If you're using a more boring root partition, it might be something like mknod -m 0660 /dev/sda1 b 8 1) So I had managed by now to gather that udev wasn't working, but I didn't know why. My first thought was to try /etc/init.d/udev start, to see if it would start. But it told me that the script is written for baselevel-2, and I shouldn't use it on baselevel-1. Following a bit of googling about what the heck a baselevel is, I gathered that I was using baselevel-1, and so the service wasn't supposed to be started that way. So it wasn't a bug that it wouldn't start that way. Another page suggested trying to run it directly, with /sbin/udevd --daemon, which gave the message error getting signalfd. That told my why it didn't start. This message was also in the logs, but for some reason I didn't look there until later. So back to Google, and I found a message on a Debian board noting that udev had started using signalfd recently. This suggested an old version might do the trick. I tried one, and it did.

[gentoo-user] Native vs Core2
Hey everyone, This guy (http://forums.gentoo.org/viewtopic-t-806844.html#6097354) says that -march=native and -march=core2 differ. Which one do I choose for my Core i5 CPU?

Re: [gentoo-user] gmonstart / jvregisterclasses in tons of binaries with commands,malware?

Yet, clamav, rkhunter, chkrootkit do not detect abnormalities. Whether I run 'strings' on the binary files or view with vim or gedit, here is what is always seen inside the binaries: __gmon_start__ http://lists.debian.org/debian-arm/2001/03/msg00034.html poi...@chicane /data/distfiles $ /lib/libc.so.6 --version GNU C Library stable release version 2.9, by Roland McGrath et al. snip hmm... it could be an issue, I suppose... but given I'm on a version of glibc far newer than the 2.1 to 2.2 transition that caused issues regarding that relocation, according to the mail referenced above... I think I'm safe, don't you? And... that's on my x86 *stable* system. _Jv_RegisterClasses http://gcc.gnu.org/ml/gcc/2002-06/msg00112.html Followed by commands which differ within each binary. If, by some luck, I've downloaded a fresh Linux ISO where binaries do not include the above two strings followed by commands, after I run an update the updated binaries suddenly contain the above two strings and other, what I believe to be, rogue strings. I've avoided the possible infection with an OpenBSD install, yet all the Linux installations and burned ISOs contain binaries with the above two strings followed by commands. Search using find within your bin and sbin directories for those two strings and see how many positives you find. Now use a text editor like vi or gedit and search through the gibberish, locate these strings and isolate the commands, if any, which follow them. Searching for gmonstart, gmon, registerclasses, jv, etc. variations of works. If you find results in your binaries, please copy/paste the commands following the gmonstart and jvregisterclasses strings so I may compare them to mine. I've purchased Linux CDs from brick + mortar stores, downloaded ISOs from different physical locations and found some CDs contained these strings in the binaries and one or two rare ones did not, but when installed/updated on a network connection the binaries replaced in the update process would show these strings!! These strings are not alone by themselves in the binaries they follow with commands with a @ mark before each command. Google results are vague, some suggest shell backdoors, every Linux user I've asked to date calls me paranoid while at the same time this knowledge comes as a surprise to them, too, when they search their binaries and find the same strings. I'm amazed by how quickly some rush to judgement and call you a paranoid for being curious about the files on your system. The strings may/may not be common, but in comparing commands which follow these strings I've noticed some which seem down right malicious! Maybe they're right, I'm just paranoid, but what am I seeing and why are these strings so common across Linux distros binaries, esp. the Jv (java?) reference? Please, any help? They're so common because they're binaries compiled with the same compiler against the same libc implementation, for the most part, and there will *always* be very similar strings resulting from BOTH of those states across anything they've had a hand in. Yes, of course, it's reasonable to be security concious, but both of the links I found for those strings are first page on Google. There's also the confusing fact that you look so heavily at the binaries while failing to take a look at the things that would be sensible reasons for the same strings between them... and grep is your friend if you're going to do any sensible auditing... you have... 1) Their own source code (may or may not have a reference) 2) Toolchain (and, really, it's the source code for these you'll want to look through) 2a) Compiler - gcc suite 2b) Linker - ld from binutils 2c) Assembler - Also binutils 3) Libraries - Anything *all* of them link to. ldd is an amazingly handy tool... 3a) libc.so.6 - glibc 3b) linux-gate.so.1 - part of the the kernel (not a real file on the system) 3c) /lib/ld-linux.so.2 - runtime component for the linker (which would be ld from binutils) And... when your own phrasing of things shows you don't even know *what* these two strings you found *do* or are *really* related to... cross posting to gentoo-security is really not necessary, though I can't guarantee the actual security experts on that list would agree... I get that feeling. -- Poison [BLX] Joshua M. Murphy

Re: [gentoo-user] Broken upgrade from udev troubles.
On Wed, Dec 16, 2009 at 10:07 PM, Tom Bennet twben...@gmail.com wrote: I spent the day recovering from a Gentoo upgrade, and thought I'd document the experience in case it helps someone else. I'm running a custom kernel 2.6.25-gentoo-r7 on amd64, though I don't think the rarer hardware is relevant. I tend to put off upgrading my Gentoo box because anytime I do, something breaks. I'm afraid I haven't changed my opinion about that. Anyway, I did emerge --update --deep world and plugged my ears. Some 600-odd packages (and a few simpler problems) later, the system seemed to be doing okay. So I thought I'd see if it could survive a reboot. No, it couldn't. On boot it failed checking the root file system and dropped into the repair shell. The reason the fsck failed is that the root pseudo device file /dev/md0, didn't exist. The root file system was actually, fine, though. Inside the repair shell, I could see all the files from my root, but there wasn't much in /dev. (I have the md stuff compiled in to the kernel, and don't use an initrd, so it wasn't an initrd problem.) Short Solution The problem was with udev, the facility which automatically populates the /dev directory. During the upgrade, emerge noted that my kernel version was a bit early, but acceptable. What was missing, apparently, was the signalfd syscall, which that kernel version either doesn't have or I hadn't configured. Apparently, udev has only started using signalfd recently, so the solution was to downgrade to an older version of udev (udev-141 to be precise). What I Actually Did To Get There Of course, I didn't know that at first. Just had a fun unbootable system. I might have been able to simply emerge the downgrade from the repair shell (the network did come up), but I didn't know to try that yet. I figured I wanted to find some way to make the system boot. Since the failing file check is done from /etc/init.d/checkroot, I added a mknod command to create the device node before trying to run the file check. At the start of the start() method: if [ ! -e /dev/md0 ] ; then mknod -m 0660 /dev/md0 b 9 0 fi It's a hack, not a solution, but it did make the system boot, to a rather crippled state. Since there were a lot of devices missing, a lot of services wouldn't start. (If you're using a more boring root partition, it might be something like mknod -m 0660 /dev/sda1 b 8 1) So I had managed by now to gather that udev wasn't working, but I didn't know why. My first thought was to try /etc/init.d/udev start, to see if it would start. But it told me that the script is written for baselevel-2, and I shouldn't use it on baselevel-1. Following a bit of googling about what the heck a baselevel is, I gathered that I was using baselevel-1, and so the service wasn't supposed to be started that way. So it wasn't a bug that it wouldn't start that way. Another page suggested trying to run it directly, with /sbin/udevd --daemon, which gave the message error getting signalfd. That told my why it didn't start. This message was also in the logs, but for some reason I didn't look there until later. So back to Google, and I found a message on a Debian board noting that udev had started using signalfd recently. This suggested an old version might do the trick. I tried one, and it did. I really only have two things to say, after reading this... First, and this really does overshadow the second in weight, thank you for the excellently presented writeup of problem *and* solution, as more often than ever should be (less so here, but across the net as a whole), problems are mentioned, solutions are offered, and rarely does a good, clear, this worked follow. Secondly... it's been my experience, with Gentoo, that things break far more often when I allow longer delays between updating than when I keep up to date with everything, and it's held true for me on both x86 and ~x86 systems (as has the headache when I've put updates off). And.. I reiterate a part of the first... Thank you for the writeup. -- Poison [BLX] Joshua M. Murphy
