Jan Vaclav 33871478b7 initrd: fix use-after-free when multiple iBFT entries fail 
The error variable is declared outside the loop but freed with
g_error_free() which does not reset the pointer to NULL. On the
next iteration, g_set_error() sees a non-NULL *err (dangling pointer)
and error->message dereferences freed memory.

Use g_clear_error() instead which also resets the pointer.

Found by Coverity (CID: USE_AFTER_FREE).

Fixes: ecc074b2f8 ('initrd: add command line parser')

nm-initrd-generator

A command line tool that generates NetworkManager configuration.

This is supposed to be run by dracut in initrd, before NetworkManager starts. It parses the kernel command line, generates configuration and quits.

See:

  • man 8 nm-initrd-generator ([www])
  • man 7 dracut.cmdline
