* common: Use new function to print status strings.Werner Koch2018-02-141-24/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | * common/asshelp2.c (vprint_assuan_status_strings): New. (print_assuan_status_strings): New. * agent/command.c (agent_write_status): Replace by call to new function. * dirmngr/server.c (dirmngr_status): Ditto. * g13/server.c (g13_status): Ditto. * g13/sh-cmd.c (g13_status): Ditto. * sm/server.c (gpgsm_status2): Ditto. * scd/command.c (send_status_info): Bump up N. -- This fixes a potential overflow if LFs are passed to the status string functions. This is actually not the case and would be wrong because neither the truncating in libassuan or our escaping is not the Right Thing. In any case the functions need to be more robust and comply to the promised interface. Thus the code has been factored out to a helper function and N has been bumped up correctly and checked in all cases. For some uses this changes the behaviour in the error case (i.e. CR or LF passed): It will now always be C-escaped and not passed to libassuan which would truncate the line at the first LF.

(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 <wk@gnupg.org>
