PACKAGE : Portage |

SUMMARY : library symlink mangling / deletion |
| 7 |
SEVERITY: System Disabling |

IMPACT : All Systems |

|
| 13 |
A bug involving the interaction of 'ldconfig' and portage has been |
| 14 |
identified for all systems using masked libraries. Libraries that |
| 15 |
have been installed but are now masked in portage will be downgraded |
| 16 |
by portage. In versions of portage prior to 2.0.43, portage creates |
| 17 |
symlinks in the library directories properly for newly merged, but |
| 18 |
older, library. A call to ldconfig causes these symlinks to be over- |
| 19 |
written with what the system(ldconfig) assumes is the best, the |
| 20 |
highest version, and then portage procedes to remove the symlinks |
| 21 |
as they match how the previous version had set them. This problem |
| 22 |
can result in users being locked out of systems as required libraries |
| 23 |
are effectively disabled. |
| 24 |
|
| 25 |
AFFECTED SYSTEMS |
| 26 |
|
| 27 |
All systems using portage prior to portage-2.0.43 are succeptable. |
| 28 |
Systems that have installed the latest versions of libraries that |
| 29 |
have since been masked in portage are of major concern, and systems |
| 30 |
with ncurses-5.3 installed can disable logins if 'emerge -u world' |
| 31 |
is performed with ncurses-5.3 masked. |
| 32 |
|
| 33 |
SOLUTION |
| 34 |
|
| 35 |
Users experiencing missing library symlinks can do the following: |
| 36 |
# ldconfig |
| 37 |
# emerge rsync |
| 38 |
# emerge '=portage-2.0.43' |
| 39 |
|
| 40 |
If a root console is not accessable the following method may be used: |
| 41 |
Systems using Grub: |
| 42 |
press 'e' on your kernel |
| 43 |
press 'e' over your kernel line |
| 44 |
append without the quotes: |
| 45 |
" init=/bin/sash" |
| 46 |
press enter to finish the changes |
| 47 |
press 'b' to boot the kernel |
| 48 |
Systems using LILO: |
| 49 |
at boot hold in left shift to get the prompt |
| 50 |
type in your kernel's label (name) |
| 51 |
You can get the list of kernel names by hitting <tab> at this point. |
| 52 |
append to that label the following: ' init=/bin/sash' |
| 53 |
You may also have to specify a 'root=' or other information. |
| 54 |
press enter to boot the kernel |
| 55 |
When at the '>' prompt type the following: |
| 56 |
> mount -o remount,rw / |
| 57 |
> /sbin/ldconfig |
| 58 |
> mount -o remount,ro |
| 59 |
> reboot |
| 60 |
|
| 61 |
After running the above Grub or LILO commands, users should update to |
| 62 |
portage-2.0.43 as stated above for users not locked out of their consoles. |
