  • glibc crypt changes

    From Benny Pedersen@2:230/0 to All on Sun Aug 15 03:39:00 2021
    Hello All!

    * sys-libs/libxcrypt
    Available versions: 4.4.20(0/1)^t ~4.4.25(0/1)^t {+compat split-usr +static-libs system test ABI_MIPS="n32 n64 o32" ABI_S390="32 64" ABI_X86="32 64 x32"}
    Homepage: https://github.com/besser82/libxcrypt
    Description: Extended crypt library for descrypt, md5crypt, bcrypt, and others

    is used when glibc have no crypt support on gentoo

    glibc is still on 2.33 not 2.34 yet

    Hey Benny!

    glibc is still on 2.33 not 2.34 yet

    +1

    Same situation with slackware. It doesn't surprise me any.

    Life is good,
    Maurice

    How do you explain this?

    how is your glibc compiled ?

    imho you still build crypt static linked into glibc, but gentoo will change that to use Xcrypt note libcrypt vs libxcrypt is not same lib

    sorry if i am incorrect

    Hey Benny!

    how is your glibc compiled ?

    I've already posted everything that matters. Perhaps I am not understanding the question?

    My configure looks like this;

    ../configure --prefix=/usr \
    --disable-werror \
    --enable-kernel=3.2 \
    --enable-stack-protector=strong \
    --with-headers=/usr/include \
    --build=$MACHTYPE \
    libc_cv_slibdir=/lib

    where MACHTYPE is x86_64-moosile-linux-gnu in the case of the glibc-2.34 toolchain. The system I am replying from is still x86_64-motorshed-linux-gnu/glibc-2.33 based.

    I know how to have fun ... and stay safe. I am also double vaxxed (Moderna) if that matters linuxie-speaking.

    libcrypt vs libxcrypt is not same lib

    I figured as much.

    sorry if i am incorrect

    No need for sorry ... yet. :::evil grin:::

    Life is good,
    Maurice

    Hey Benny!

    how is your glibc compiled ?

    Here is a follow up using stable glibc-2.34 source from gnu.org;

    # /lib/libc.so.6 | printf " %s\n" "$(head -1)"
    GNU C Library (GNU libc) stable release version 2.34.

    Of special interest regarding shadow-4.8.1 and libcrypt.so.1 from glibc-2.34;

    # ldd /usr/bin/passwd | sed 's/\t/ /'
    linux-vdso.so.1 (0x00007ffe401fb000)
    libcrypt.so.1 => /lib/libcrypt.so.1 (0x00007f5645368000)
    libc.so.6 => /lib/libc.so.6 (0x00007f56451ad000)
    /lib/ld-linux-x86-64.so.2 (0x00007f56453a3000)

    I don't see a problem. Do you?

    Life is good,

    That is a feature.

    Hey Benny!

    Exactly. I definetly would have know if I statically linked it in, which I don't even have at the moment.

    i only spoted that slackware is have pam in

    I noticed that too. I haven't done anything with pam lately and am not sure I ever will. I may call it quits on the gcc-11.2.0/glibc-2.33/linux-5.13.12 I am currently calling a stable root/boot. As far as shadow is concerned I am stuck at 4.8.2 and no pam dependency.

    Speaking of which I have the newest shadow-4.9 on a glibc-2.34 partition that I have yet to test boot. Maybe later today. shadow-4.9 doesn't appear to work on a glibc-2.33 based system for some unknown reason to me at the moment.

    Life is good,
