Many stable fixes came in since the last bump, a few of which were actually already present. Notable ones not yet present include a few guest-triggerable assert fixes, some AHCI/IDE fixes (including the fix for bug #2784), TGC fixes for i386 and ARM, VirtIO fixes, fix to avoid VNC clipboard denial-of-service. The reentrancy patches that landed upstream/stable were a newer version than the ones backported initially here, so it was necessary to explicitly drop them before rebase (which then picked up the upstream version). There were no other conflicts. Signed-off-by: Fiona Ebner <f.ebner@proxmox.com>

Subject: [PATCH] PVE: fall back to open-iscsi initiatorname
|
|
|
|
When no explicit option is given, try reading the initiator name from
|
|
/etc/iscsi/initiatorname.iscsi and only use the generic fallback, i.e.
|
|
iqn.2008-11.org.linux-kvmXXX, as a third alternative.
|
|
|
|
This avoids the need to add an explicit option for vma and to explicitly set it
|
|
for each call to qemu that deals with iSCSI disks, while still allowing to set
|
|
the option if a different name is needed.
|
|
|
|
According to RFC 3720, an initiator name is at most 223 bytes long, so the
|
|
4 KiB buffer is big enough, even if many whitespaces are used.
