Package: tiny-initramfs
Version: 0.1-2
Severity: critical
Recent Debian kernels (4.8.x) have disabled support for legacy vsyscall
emulation.
changelog entry from kernel packages:
* [amd64] Enable LEGACY_VSYSCALL_NONE instead of LEGACY_VSYSCALL_EMULATE.
This breaks (e)glibc 2.13 and earlier, and can be reverted using the
kernel
parameter: vsyscall=emulate
This causes problems with tiny-initramfs as the init binary is linked
against an old version of dietlibc which uses the vsyscall for accessing
the kernel gettimeofday functions. This manifests as the init process being
killed when it attempts to access the vsyscall interface which renders the
system unbootable.
dietlibc 0.33 adds changes to use the kernel vDSO instead of the legacy
vsyscall interface.
I have tested rebuilding tiny-initramfs against the latest dietlibc in
Debian (0.34~cvs20160606-3) and the rebuilt init binary works successfully
on 4.8.x kernels.
Setting severity to critical as this renders systems using tiny-initramfs
unbootable when the upgraded kernel package is installed. It would be great
to get an updated tiny-initramfs package rebuilt against the latest
dietlibc.
