(sh_dmcrypt_suspend_container): New. (sh_dmcrypt_resume_container): New. * g13/call-syshelp.c (call_syshelp_run_suspend): New. (call_syshelp_run_resume): New. -- The --suspend command can be used before a hibernate operation to make the encrypted partition inaccessible and wipe the key from the memory. Before --suspend is called a sync(1) should be run to make sure that their are no dirty buffers (dmsetup, as called by g13, actually does this for you but it does not harm to do it anyway. After the partition has been suspended a echo 3 >proc/sys/vm/drop_caches required to flush all caches which may still have content from the encrypted partition. The --resume command reverses the effect of the suspend but to do this it needs to decrypt again. Now, if the .gnupg directory lives on the encrypted partition this will be problematic because due to the suspend all processes accessing data on the encrypted partition will be put into an uninterruptible sleep (ps(1) shows a state of 'D'). This needs to be avoided. A workaround is to have a separate GnuPG home directory (say, "~/.gnupg-fallback") with only the public keys required to decrypt the partition along with a properly setup conf files. A GNUPGHOME=$(pwd)/.gnupg-fallback g13 --resume should then be able to resume the encrypted partition using the private key stored on a smartcard. The implementation is pretty basic right now but useful to me. Signed-off-by: Werner Koch <[email protected]>

* Change all quotes in strings and comments to the new GNU standard.Werner Koch2012-06-051-11/+11
| | | | | | | | | | | | | | | | | | | The asymmetric quotes used by GNU in the past (`...') don't render nicely on modern systems. We now use two \x27 characters ('...'). The proper solution would be to use the correct Unicode symmetric quotes here. However this has the disadvantage that the system requires Unicode support. We don't want that today. If Unicode is available a generated po file can be used to output proper quotes. A simple sed script like the one used for en@quote is sufficient to change them. The changes have been done by applying sed -i "s/\`\([^'\`]*\)'/'\1'/g" to most files and fixing obvious problems by hand. The msgid strings in the po files were fixed with a similar command.
* Add a flag parameter to dotlock_create.Werner Koch2011-09-281-1/+1

| | | | | | | | We better do this once and for all instead of cluttering all future commits with diffs of trailing white spaces. In the majority of cases blank or single lines are affected and thus this change won't disturb a git blame too much. For future commits the pre-commit scripts checks that this won't happen again.
