* | Found debian wheezy useradd bug: useradd did terminates and eats 100%Thomas Osterried2015-05-011-10/+78
|/ | | | | | | | | | | | | | | | | | | cpu power, if it was called from axspawn. This could be prevented if SIGCHLD is masked. To increase security, no longer call useradd via system() but fork() and execve(). Fixed a bug when useradd failed then the login process continued anyway. Empty lines in axspawn.conf are now valid. The user_shell config variable is optional. If not specified, /bin/bash is used. Except: if create_with_useradd is configured and there's a config file /etc/default/useradd, then it's not passed to useradd in order to let him choose.

* Christoph Rueckert <dk2crn> had an issue with OpenSuse 11.2.Thomas Osterried2010-03-311-3/+3
| | | | | | | | | | login -f -h <protocol> <as_user> did not work. login -h <protocol> -f <as_user> did work. Imho, OpenSUSE meessed up login's getopt()... On the other hand, we have no problems to switch the position of arguments - as long as there's not another linux demanding another position ;)
* Convert spelling of Joerg Reuter's name from umlaut to oe.Ralf Baechle2009-06-271-2/+2
| | | | | In a world that is caught between ISO 8859-1, ISO 8859-15 and UTF-8 non-ASCII characters are a guaranteed mess, still.
* Remove use of backwards compatibility header name.Ralf Baechle2009-06-211-9/+1
| | | | | | Glibc as old as 2.2 provides working headers under the right name and if not libax25 would install headers under the right name so this has become redundant and ugly.
* Fix type of length argument to sockset syscalls.Ralf Baechle2009-06-141-3/+5
| | | | | | | | Various socket syscalls receive a length argument that should be a socklen_t rsp. a ptr to a socklen_t but instead int rsp. ptr to int were being passed. While in theory this was a bug it's harmless as dangerously large values would not be used but the issue manifested itself in a significant number of compilation warnings.
* Fix utmp time codeRalf Baechle2009-06-141-4/+10
| | | | | | | | | | | | | | | | | | | Thanks to using the antiquated time(2) call the microsecond field of the struct utmp being manipulated was never initialized resulting in random values. On some 64-bit systems this also manifested itself in below warnings. axspawn.c: In function ‘cleanup’: axspawn.c:1017: warning: passing argument 1 of ‘time’ from incompatible pointer type /usr/include/time.h:186: note: expected ‘time_t *’ but argument is of type ‘int32_t *’ [...] axspawn.c: In function ‘main’: [...] axspawn.c:1693: warning: passing argument 1 of ‘time’ from incompatible pointer type /usr/include/time.h:186: note: expected ‘time_t *’ but argument is of type ‘int32_t *’ Fixed by changing it to the recommended initialization sequenze based on gettimeofday().

* typo: embeded is embeddedThomas Osterried2008-04-131-6/+6
|
* axspawn on embeded systems like openwrt:Thomas Osterried2008-04-131-33/+103
| | | | | | | | | | | | on those systems, things are not as you expect. i.e., /bin/login is a shell script and implements boot-specific actions only (login without root password, etc..). The assumption that /bin/login -f username causes user as uid > 0 to login is wrong; user may gain root rights. axspawn now implements partially (thus, in the important points) what login assures. axspawn should be involked with the option --embeded when called from ax25d.
* new feature: bcpasswd authentication type "unix".Thomas Osterried2008-02-161-3/+7
| | | | | user has now also the choice to use the standard unix passwd/shadow authentication
* - bugfix: if /etc/skel/.profile exists, and /etc/ax25/ax25.profile,Thomas Osterried2007-03-111-4/+41
| | | | | | | | | | then .profile is copied, and without deletion the contense of ax25.profile is overwritten. to .profile. This lead to garbage. - Some useradd implementations refuse to add the user if his homedir already exists. But we need the function which builds the subtree /home/hams/dl9.../, because useradd does not make the missing subdirs by itself (instead, it's a severe error condition for useradd)

* - fdlock(): fixed potential lock due to return without unlockThomas Osterried2005-12-101-11/+63
| | | | | | | | | - new password methods (read pwcheck for more info) - mode for homedirectory: new config option secure_home. if not set, new homedirectories become drwxr-xr-x if set, new homedirectories become drwx-----x. other=x, because otherwise uses would be iritating that for e.g. their public_html is not accessable..
* - fixed bug when downloading large messages (where linux kernel returnsThomas Osterried2005-10-301-91/+768
| | | | | | | | | -EAGAIN, when buffers get empty, which leaded to data loss) - fixed bug when '\r\n' was splited into two reads (trailing \r in the first read, starting \n in the second read) -> resulted in an empty line - better FD_SET(&fdread) handling - added //COMP hufman compression - could make use of the useradd(8) program for generating new accounts
