* common: New functions gnupg_daemon_rootdir and gnupg_chdir.Werner Koch2017-07-251-1/+2
| | | | | | | | | | | * common/sysutils.c (gnupg_chdir): New. * common/homedir.c (gnupg_daemon_rootdir): New. * agent/gpg-agent.c (main): Use these functions instead chdir("/"). * dirmngr/dirmngr.c (main): Ditto. * scd/scdaemon.c (main): Ditto. -- Signed-off-by: Werner Koch <[email protected]>
* agent: Shutdown on removal of the home directory.Werner Koch2017-06-231-0/+1
| | | | | | | | | | | | | | | * common/sysutils.c (gnupg_inotify_watch_delete_self): New. * agent/gpg-agent.c (handle_connections): Rename my_inotify_fd to sock_inotify_fd. (handle_connections): Add home_inotify_fd to watch the home directory. -- GnuPG-bug-id: 3218 Note that we should add this also to dirmngr. And for non-Linux systems a stat in ticker should be implemented. Signed-off-by: Werner Koch <[email protected]>
* gpg,common: Make sure that all fd given are valid.Justus Winter2017-02-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * common/sysutils.c (gnupg_fd_valid): New function. * common/sysutils.h (gnupg_fd_valid): New declaration. * common/logging.c (log_set_file): Use the new function. * g10/cpr.c (set_status_fd): Likewise. * g10/gpg.c (main): Likewise. * g10/keylist.c (read_sessionkey_from_fd): Likewise. * g10/passphrase.c (set_attrib_fd): Likewise. * tests/openpgp/Makefile.am (XTESTS): Add the new test. * tests/openpgp/issue2941.scm: New file. -- Consider a situation where the user passes "--status-fd 3" but file descriptor 3 is not open. During the course of executing the rest of the commands, it's possible that gpg itself will open some files, and file descriptor 3 will get allocated. In this situation, the status information will be appended directly to whatever file happens to have landed on fd 3 (the trustdb? the keyring?). This is a potential data destruction issue for all writable file descriptor options: --status-fd --attribute-fd --logger-fd It's also a potential issue for readable file descriptor options, but the risk is merely weird behavior, and not data corruption: --override-session-key-fd --passphrase-fd --command-fd Fixes this by checking whether the fd is valid early on before using it.

(handle_connections): Remove HAVE_INOTIFY_INIT protected code and use the new functions. -- When removing not a simple socket file but the entire directory the old code missed most events and thus did not worked properly. IN_DELETE_SELF has also been added to the watch list to detect a removal of the directory. However, in all tests that event was not triggered. The only way it could be triggered was by not watching the socket dir but an arbitary directory and rmdir that. GnuPG-bug-id: 2756 Signed-off-by: Werner Koch <[email protected]>

* Change license for some files in common to LGPLv3+/GPLv2+.Werner Koch2012-04-201-5/+15
| | | | | | | | | | | | | | | | | | | | | | | Having the LGPL on the common GnuPG code helps to share code between GnuPG and related projects (like GPGME and Libassuan).

* Add code for explicit selection of pooled A records.Werner Koch2011-04-121-0/+1
| | | | | | | | | | | To better cope with round robin pooled A records like keys.gnupg.net we need to keep some information on unresponsive hosts etc. What we do now is to resolve the hostnames, remember them and select a random one. If a host is dead it will be marked and a different one selected. This is intended to solve the problem of long timeouts due to unresponsive hosts. The code is not yet finished but selection works.
