This removes a duplicate condition check by adding a common surrounding
if block.
This also change a confusing if check: "(X && Y) && Z" to simply "X && Y && Z"
SuspendState= not to include "disk"
I don't know why these existed in the first place, but as I
justified in the comments, it's simply not sensible to allow
HibernateState= or HybridSleepState= to take values other than
'disk'. So let's just remove those options. Also, SuspendState=
should not contain 'disk'.
Let's split out the logic that actually generates the word to measure to
PCRs into a new helper file pcrextend-util.[ch].
This we can later reuse to calculate PCR measurement predictions ahead
of time.
These are not used outside of tpm2-util.[ch], and the way they merge
public/private key pair into one blob is kinda specific to our
implementation, hence better should be hidden away, and not used for new
code anyway.
We'll soon have a function for determining the name of an NV index,
hence let's rename the existing function for the same of a public key to
make clear it's about public keys only.
modprobe treats "-" and "_" interchangeably, thereby avoiding frequent
errors because some module names contain dashes and others underscores.
Because modprobe@.service unescapes the instance name, an attempt to
start "modprobe@dm-crypt.service" will run "modprobe -abq dm/crypt",
which is doomed to fail. "modprobe@dm_crypt.service" will work as
expected. Thus unescaping the instance name has surprising side effects.
Use "%i" instead.
This is convenient when the server supports IPv6 only mode.
Otherwise, we cannot request a new address during the client is waiting an
IPv6 connectivity. Note, the minimal timespan is 5min, and a server may
send a quite large value.
The condition was outdated, e.g. SELECTING state does not have a lease.
See client_handle_offer() and client_enter_requesting().
The condition based on the state may become much complex in the future.
Let's use simpler condition.
After 7470b80763, we refuse
to hibernate if we fail to write HibernateLocation EFI
variable and resume= is not set. Let's teach sleep_supported
to follow the practice too.
* "HibernateLocation" struct is renamed to HibernationDevice
to avoid ambiguity with the EFI variable. Also, it no longer
takes the reference to a SwapEntry object, since it's really
unnecessary (only SwapEntry.path is used), but increases complexity.
* SwapEntry is no longer used externally.
* find_hibernate_location is split into read_swap_entries and
find_suitable_hibernation_device. The former reads all swap entries
into SwapEntries object for later use.
* Make use of btrfs_get_file_physical_offset_fd
