* indent: Fix spellingDaniel Kahn Gillmor2024-05-311-1/+1
| | | | | | | | | | | | | -- These are non-substantive corrections for minor spelling mistakes within the GnuPG codebase. With something like this applied to the codebase, and a judiciously tuned spellchecker integrated as part of a standard test suite, it should be possible to keep a uniform orthography within the project. GnuPG-bug-id: 7116
* g13: New option --no-mount.Werner Koch2024-01-091-25/+39
| | | | | | | | | | | | | | | | | | | | | * g13/g13.c (oNoMount): New. (opts): Add --no-mount. (main): Implement this. * g13/g13-common.h (opt): Add field no_mount. * common/status.h (STATUS_PLAINDEV): New. * g13/sh-cmd.c (has_option): Uncomment. (cmd_mount): Add option --no-mount and pass down. * g13/sh-dmcrypt.c (sh_dmcrypt_mount_container): Add arg nomount and emit PLAINDEV status line. (sh_dmcrypt_umount_container): Rund findmnt before umount. -- This option can be used to decrypt a device but not to mount it. For example to run fsck first. A command or option to run fsck before a mount will eventually be added. The use of findmnt is needed so that we can easily remove a device which has not been mounted.

(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]>
