grub2-efi-xen-removable.patch Normal file

@ -0,0 +1,113 @@
From: Michael Chang <mchang@suse.com>
References: bsc#1085842
Patch-Mainline: no
The grub can be installed with removable option to support booting from
removable media with standard UEFI default file path of the form:
\EFI\BOOT\BOOT{machine type short-name}.EFI
It does not make use of distributor directory, which becomes a problem for UEFI
Xen installation as it requires that directory to be present for storing xen
stuff like chainloaded hypervisor, xen kernel and so on. Moreover it makes bad
assumption that hypervisor will be chainloaded by grub under the same
directory, which is also not always true.
This patch fixes the problem by ensuring the directory available to Xen
installation if any Xen hypervisor found and independent to grub boot path
$cmdpath to work.

Subject: unix exec: avoid atexit handlers when child exits
Git-commit: e75cf4a58b5eaf482804e5e1b2cc7d4399df350e
Patch-mainline: Yes, but not released yet
References: bsc#1086670
The `grub_util_exec_redirect_all` helper function can be used to
spawn an executable and redirect its output to some files. After calling
`fork()`, the parent will wait for the child to terminate with
`waitpid()` while the child prepares its file descriptors, environment
and finally calls `execvp()`. If something in the children's setup
fails, it will stop by calling `exit(127)`.
Calling `exit()` will cause any function registered via `atexit()` to be
executed, which is usually the wrong thing to do in a child. And
actually, one can easily observe faulty behaviour on musl-based systems
without modprobe(8) installed: executing `grub-install --help` will call
`grub_util_exec_redirect_all` with "modprobe", which obviously fails if
modprobe(8) is not installed. Due to the child now exiting and invoking
the `atexit()` handlers, it will clean up some data structures of the
parent and cause it to be deadlocked in the `waitpid()` syscall.
The issue can easily be fixed by calling `_exit(127)` instead, which is
especially designed to be called when the atexit-handlers should not be
executed.
