[lfs-support] systemd behaviour
Hallo dear list, for years I have a small helper in /etc/profile.d to search for an existing ssh-agent instance for my user and set the SSH_* environment variables accordingly if it finds one. If none is running it does the usual eval $(ssh-agent) thing. In the last days I built LFS 10.1 systemd version to compare sysV and systemd styles and educate myself further. When exiting and re-entering I noticed that it asks me - again - for my SSH key credentials and eventually my previous instance of ssh-agent is gone. Is it standard behaviour of systemd to kill all processes since login? My sysV install behaves like expected and ssh-agent stays alive. How would I start ssh-agent so that it will survive logoff? An additional layer of "nohup"?

[lfs-support] backscrolling with shift+cursor

[lfs-support] ssh connect fails at kexinit msg 20 preauth
Hallo dear list, I have successfully compiled LFS 10.1 on my legacy P4 (32 bit) with jhalfs-4212 (svn) on an existing LFS 10.0. Compilation went fine overnight, after installing a kernel it boots fine. Next step was compiling openssh 8.4 to make it headless again (I had exchanged some cables on my KVM switch to watch it boot for the first time). Compilation went fine here as well, sandbox user exists, sshd starts, but connection fails and I have absolutely no clue what goes wrong. sshd_config and host keys are the same files I use on the same system, LFS 10.0 partition. I tried with different users, ssh keys, tried permissions on .ssh, authorized_keys, etc. The last ssh message is "[server ip] closed connection". Using -vvv I see it fails after exchanging msg type 20 preauth kexinit. I started sshd -e -D -d -d -d and the last messages here tell me the exact same thing: kexinit msg type 20 preauth kexinit happens and then the sandbox cleanup kicks in. There is no error message why it fails in this stage. LFS 10.1 uses openssl 1.1.1j which works fine for me on the other system (I recently started to upgrade all my systems to 1.1.1k last week but I'm not sure this would make a difference for my current problem). Usually for ssh problems it boils down to some permissions too wide open but I think I got that covered. I even checked /tmp for 1777 which is my favourite to overlook ;) I'm out of ideas where to look so maybe someone here has some hints for me please?

[lfs-support] how to find out grub boot path
Hallo, is it possible to query the "breadcrumb" of a grub boot process? Say I have multiple partitions, e.g. /dev/sda1, /dev/sda5, /dev/sda6, with different LFS versions. When booting grub chooses grub.cfg from the partition that ran the last grub-install command (e.g. /dev/sda1). But: if I choose manually to boot from e.g. /dev/sda5, it would still have used the grub.cfg from /dev/sda1, and if I wanted to change boot parameters I'd have to edit /dev/sda1 grub.cfg.

Hallo, >> For some reason my /tmp directory keeps resetting to 0755 a typical reason for this problem is unpacking an archive file in /tmp which contains the "." current directory. tar will happily reset the permissions and destroy the 1777 setting.

Re: [lfs-support] compile 32-bit kernel on a 64-bit LFS?
Hallo,
>> Would a 32-bit kernel work if I compile it on a 64-bit machine with the
>> 32-bit config taken from the current compile system?
> I think you need at least a multilib gcc.
I had success! After a bit of experimenting I found the following to work:
take the .config from the 32-bit system and copy into the usual place on
the compile machine. A multilib gcc is not required. I did not build the
LFS for my 64-bit machine with multilib afair and it works.
Since you cannot "install" and "modules_install" you need to give
temporary install paths for the kernel and the modules. These are 2
distinct environment variables that have to be set.
Afterwards you can collect the package and move from the 64-bit system
to the 32-bit system.
cd /sources/linux-5.3.15
mkdir -p build/{boot,lib}
export INSTALL_PATH=/sources/linux-5.3.15/build/boot
export INSTALL_MOD_PATH=/sources/linux-5.3.15/build
make install modules_install
tar -C build -cf ../linux-5.3.15-32.tar boot lib
The tar file needs to be unpacked in the root directory of the 32-bit
machine, grub.cfg needs a new entry pointing to the kernel and you're done.
Failed attempt: use only the compiled kernel and try to keep the
previously installed modules (since I had the same kernel version
already running on the 32-bit system). Obviously the kernel verifies
some compiler version-specific signature and refuses to load kernel
modules compiled with a different gcc. So you need to install kernel and
modules from the same compile but that should be the usual case.
PS: is System.map required for normal operation or is it only required
for devs doing some sort of bug tracking? I'm tempted to omit the file.
Tschau...Thomas

[lfs-support] compile 32-bit kernel on a 64-bit LFS?
Hallo, I have some servers running with 32-bit LFS (intentionally). Longterm I plan to switch to 64 bit, but not right now. I'm contemplating switching the kernel compile from a 32-bit machine to one of my 64-bit systems to win some time.

Would a 32-bit kernel work if I compile it on a 64-bit machine with the 32-bit config taken from the current compile system? Do I need some additional parameters or switches to signal that it's kind of a cross-compile for another CPU?

Hallo, I assume those first and last were for packages that aren't in BLFS ? there were also packages from LFS and BLFS which showed that. Imho it's not directly stemming from changes in glibc but in stricter gcc checking, more warnings enabled and less assuming what the programmer wanted to express with his code. My previous daily driver LFS build was 7.7, and I had one test machine with 7.10. Then I started again with LFS 8.0 to get my hands on a gcc 7+ to play around with meltdown, spectre etc. fixes.

Re: [lfs-support] some observations about LFS 8.3 + jhalfs
Hallo, For the "rm" instructions, I'd suggest not adding -f, because usually, where is that happening? I have no actual example for rm where -f would be necessary, this was just something coming to my mind when I wrote about forcing interactive mode with cp or mv and remove -i switches there. I had 158-kernel hanging forever because it was invoked from make and I could not give an answer to the command. Professionally I'm responsible for automation of install and operations for a company with some blue letters in its name so I tend to be overcautious with scripts that potentially run headless, i.e. from cron, puppet, ansible etc. I hate unexpected stuff like aliased cp/mv commands where -i is forced upon me. Lots of my scripts contain "unalias mv" or "\mv" to be sure of how things are working. As a sidenote: the BLFS install of openssh hangs for the same reason. On a fresh machine where there are no keys yet the make install asks questions and obviously no answer is possible: ...

Re: [lfs-support] some observations about LFS 8.3 + jhalfs
Hallo and a happy new year, On all occasions the makefile stopped after 146-revisedchroot with the sudo the bug. Can you send me the "configuration" file you have used? I'll try to recreate. I started fresh yesterday, and now the Makefile contains CHROOT2. I hope I can remember which options I used previously. Apart from that I'm quite happy with jhalfs. found another one: ncurses from LFS is built without libtinfo, so I can't run BLFS first stage make in /blfs_root - it's bailing out on not being able to load libtinfo.so for mconf. I modified the configure options for ch. 6 ncurses and added --with-termlib=tinfo\ This works and I could invoke make for setting BLFS options. Any idea why I cannot use passwd in the chroot environment? I tried to set the root password before rebooting, and passwd simply does not ask for keyboard input. I worked around this by copying the password line for root from /etc/shadow to /mnt/lfs/etc/shadow.

[lfs-support] some observations about LFS 8.3 + jhalfs
Hallo, I've been entertaining myself by building LFS 8.3 over the weekend. Originally I wanted to measure the difference between an old Samsung SATA drive and a more recent SSD on an i5-6500 with 8 GB RAM but it turned out to be more of an jhalfs adventure ;) I'm using jhalfs from svn, not the 2.4 release which did not work for me in previous tries. On all occasions the makefile stopped after 146-revisedchroot with the sudo usage message. Target 146-revisedchroot OK mk_BOOT You are going to CHROOT into /mnt/lfs lfs a password is required usage: sudo -h | -K | -k | -V It turns out that the CHROOT2 definition is missing from the generated Makefile. After I added that (basically CHROOT1 without /tools) I could continue. Next thing I noticed: if I have a common /boot partition where kernel and config file from a previous build (or from parallel installations) exist the "cp -iv" in 158-kernel effectively sends the machine to an infinite loop. It waits for confirmation to overwrite (-i) but there's no possibility to do that in a headless process. Generally since interactive commands do not go well together with makefile automation I suggest the script template removes -i from cp, mv and similar commands. For the same reason rm should always include -f in automated scripts in case something happens to be readonly. Apart from that I'm quite happy with jhalfs. Thanks and have a happy new year.

I'd simply like to have the possibility to set the correct video mode when I activate that particular port on the KVM. The system receives a bunch of video parameters upon boot, but if that port on the KVM is not the active one it is 1024x768 and not the real setting that the monitor reports to the KVM switch.

[lfs-support] reset video hardware settings
Hallo, I have a question regarding setting the video mode. During boot the kernel switches to a mode suitable to the monitor capabilities (for my monitor with 1920x1200 this would be 75 rows x 240 cols) if the monitor supports this. Now here's where my problem starts: I use a 4-port KVM switch which delivers a default mode of 1024x768 to the 3 ports not selected. When an LFS system boots non-selected it switches to another video mode and size (48 rows x 128 cols). Is it possible to force-set the video mode after boot? Is this a separate package with some CLI or is this not possible at all? I have tried to follow the steps in the "console" init script but this didn't help me - it sets a font, but not the basic video mode.

Your suggestion is helpful but still only a workaround to make the shell aware of the change - I'd like to undo the resolution change caused by the KVM hiccup.

[lfs-support] kernel 4.14.14 compile needs gcc patches?
Hallo, am I right in understanding that for compiling a new kernel with retpoline resiliency I need a patched gcc until this is covered in an official gcc release? Would it be possible to build a concurrent intermediate gcc which does not affect the mainline one by choosing some different env variables?

[lfs-support] reset console size/mode
Hallo, I'm using a KVM switch at home to connect 4 PCs to one keyboard, mouse and screen. This KVM switch simulates 1024x768 resolution for the machines that are currently not active. Under unclear situations (to me) the LFS machine looses the settings for size and resolution hardware-wise, but still thinks it's got the initial size for display. This means I'm seeing a bigger font that I want to, and the lower part of the screen is off. stty reports "rows 67; columns 237" (24" screen, 1920x1200) but to me it looks more like 132x80. Is there a command to force a reset of the screen without rebooting? I notice the resolution change happens quite early during kernel start but I was hoping there is a command to repeat it later.

Re: [lfs-support] Intel microcode updates adding confusion?
Hallo,

I dowloaded the 2018 microcode package and to my big surprise I found
files for old CPUs where there was no microcode update before.
06-17-06
06-0f-0b (two variants of Core2 Duo)
Here's a little shell script to create initrd for microcode update early
loading like suggested in the BLFS book. It's simply the code from there
brushed up by looking up the CPU version. Change if you use AMD instead
of intel.
You need to add a line to /boot/grub/grub.cfg if it isn't there already.
The microcode file needs to be available in /sources.
menuentry "4.14.13-lfs-8.1" {
set root=(hd0,1)
linux /boot/vmlinuz-4.14.13-lfs-8.1 root=/dev/sda1 ro
initrd /boot/microcode.img

#!/bin/sh
cd /sources
mc=$(ls -1rt microcode*| tail -1)
test -z "${mc}" && exit 1
cpu=$(awk '/^cpu family.:/{family=$NF}
/^model..:/{model=$NF}
/^stepping.:/{stepping=$NF}

tar xf "${mc}" intel-ucode/"${cpu}"
test -f intel-ucode/"${cpu}" || exit 1

[lfs-support] some thoughts on building lfs 8.0 + 8.1
Hallo, during winter vacation I had some fun building LFS again; I wanted to dive into UEFI systems. I installed Fedora 27 on a machine with an old-ish i5-3350, 16 GB RAM and 256 GB SSD. Fedora 27 comes with gcc 7.2, and this combination cannot build LFS 8.0 without changes. This information is obviously outdated because LFS 8.1 is out ;), but FYI here's why: gcc 7.2 is strictly conforming to the new ISO C/C++ standards and comes with some new constraints, both for syntax and semantics of source code. For some integer types you need to include the new , and additionally it will choke on some code that previously was accepted. You cannot compile the LFS 8.0-included gcc 6.3.0, there's a change to ubsan.c required (if you still want to build 8.0 for some reason). src/gcc-6.3.0/gcc/ubsan.c: 1474:23: error: ISO C++ forbids comparison between pointer and integer [-fpermissive] fix is simple: - || xloc.file == '0' || xloc.file[0] == 'xff' + || xloc.file[0] == '0' || xloc.file[0] == 'xff' Tschau...Thomas -- "Do you wanna be a legend or a passing footprint on the sands of time?" signature.asc Description: OpenPGP digital signature -- http://lists.linuxfromscratch.org/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page Do not top post on this list.

to the best of my knowledge all linux distro CDs contain an option to
boot into memtest86. It is a very small binary, and I include it in all
of my machines for checking when something goes awry and I have no clue.
You might simply copy it to your build machine, include a menu entry and
run it from your boot device.
menuentry 'Memory test (memtest86+)' {
set root=(hd0,1)
knetbsd /boot/memtest86+.elf

Re: [lfs-support] 5.20. Diffutils-3.6 - mysterious sed
Hallo, > I started wondering about the purpose of this line: > sed -i '233,237 s/max)/max \\/' lib/intprops.h it seems that the surrounding #define is 0 in your case so you don't encounter the bad macro definition. The sed introduces a syntax error, too, so it seems noone ever evaluated that. Of course you can't replace the closing parenthesis with a \\ to continue the line. The lines look like this: (the first one is #226 just to better show the context) /* True if __builtin_add_overflow (A, B, P) works when P is null. */ #define _GL_HAS_BUILTIN_OVERFLOW_WITH_NULL (7 <= __GNUC__) You'd encounter the problem only when LFS moves to gcc >= version 7. # echo "__GNUC__" | gcc -I. -E - # 1 "" # 1 "" # 1 "" # 31 "" # 1 "/usr/include/stdc-predef.h" 1 3 4 # 32 "" 2 # 1 "" 6 #if _GL_HAS_BUILTIN_OVERFLOW_WITH_NULL --> (the following line is # 233) # define _GL_ADD_OVERFLOW(a, b, min, max) __builtin_add_overflow (a, b, (__typeof__ ((a) + (b)) *) 0) # define _GL_SUBTRACT_OVERFLOW(a, b, min, max) __builtin_sub_overflow (a, b, (__typeof__ ((a) - (b)) *) 0) # define _GL_MULTIPLY_OVERFLOW(a, b, min, max) __builtin_mul_overflow (a, b, (__typeof__ ((a) * (b)) *) 0) #else > I looked at lib/intprops.h and it didn't seem like there was a syntax error > there. Technically the old version not a syntax error, the macros are defined as "existing" but not with the semantical contents that was intended. I guess the intention was to write something like this # define _GL_ADD_OVERFLOW(a, b, min, max) \\ __builtin_add_overflow (a, b, (__typeof__ ((a) + (b)) *) 0) and you'd need both ) and \\ to make it syntactically correct. You can verify the parsed C code without macros, i.e. after all macros have been replaced, when you apply gcc -E to your sourcecode (together with all the switches and -D you'd usually use there). When I use this technique the last line from intprops.h is # 84. /sources/diffutils-3.5/lib # gcc -I. -E xstrtol.c | grep "intprop" # 1 "intprops.h" 1 ... # 84 "intprops.h" 3 4 # 84 "intprops.h" Tschau...Thomas -- "Do you wanna be a legend or a passing footprint on the sands of time?" signature.asc Description: OpenPGP digital signature -- http://lists.linuxfromscratch.org/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page Do not top post on this list.

[lfs-support] jhalfs pre-check suggestion
Hallo, I've tried jhalfs in the latest 2.4 version and it works quite nicely for me (used it some years ago to build 6.something). However it failed for me during 076-glibc today because I made a dumb mistake. I entered a bad timezone name which I only later realized would not work because there's no corresponding file in the timezone repository. I used "CET-1" instead of Europe/Berlin (for me in Germany). This is wrong even more because we have DST in effect for 2 weeks now ;) May I suggest to add a sanity check that the desired timezone is a valid name and exists in /usr/share/zoneinfo?

[lfs-support] should usb-sticks work with base LFS?
Hallo, I have built an LFS 7.10 system (without systemd) and I'm quite happy with it so far, everything works great. Now I wanted to transfer some files so I connected a memory stick but there's no device to mount. I'm unsure about whether I should expect an USB stick to work with base LFS or not. When I connect the memory stick the kernel messages report the USB device and recognize manufacturer etc., but I don't see a corresponding node created in /dev. My kernel is compiled with USB support and DOS/FAT/NTFS filesystems as modules. Admittedly I'm not entirely sure how udev is supposed to work. The rules syntax suggest that the kernel already provides something like "sdb" and the udev rules can work with that. I've grabbed a similar-looking rule from an Ubuntu wiki but it did not work as I hoped. Can someone please give me some hints and pointers what I should do next? Is this a debugging-something problem or an installing-something problem? Thanks ;) Tschau...Thomas -- "Do you wanna be a legend or a passing footprint on the sands of time?" signature.asc Description: OpenPGP digital signature -- http://lists.linuxfromscratch.org/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page Do not top post on this list.
