* su: add note about ECHO on --ptyKarel Zak2019-03-061-0/+4
| | | | Signed-off-by: Karel Zak <kzak@redhat.com>
* su/runuser: don't mark --pty as experimental, add it to runuser.1 tooKarel Zak2019-03-041-0/+9
| | | | | | | | | * let's assume that --pty is stable enough that we do not have to remove it ;-) * add --pty to the runuser.1 man page Addresses: https://github.com/karelzak/util-linux/issues/760 Signed-off-by: Karel Zak <kzak@redhat.com>
* su-common.c: prefer ENV_SUPATH over ENV_ROOTPATHStanislav Brabec2019-01-101-1/+1
| | | | | | | | ENV_SUPATH and ENV_ROOTPATH are equivalent and ENV_ROOTPATH takes precedence in both login and su. It makes no sense. More logical would be precedence of ENV_SUPATH in su and ENV_ROOTPATH in login. Signed-off-by: Stanislav Brabec <sbrabec@suse.cz>

* su: add --whitelist-environmentKarel Zak2018-08-151-0/+10
| | | | | | | | | | | | | | | | | | | * usable with --login to whitelist specified environment variables * the list is ignored for the core variables like HOME, SHELL, USER, LOGNAME and PATH (su --login always resets these variables) Note that su(1) requires password and after successful authentication user has full control over the session, so he can set arbitrary environment variables. The whitelist makes things more user friendly only. The patch removes unnecessary optimization when allocate environ[]. It seems better to keep all in glibc hands and just reset the environment array only. Addresses: https://github.com/karelzak/util-linux/issues/221 Signed-off-by: Karel Zak <kzak@redhat.com>

* docs: replace FTP by HTTPS in kernel.org URLsSébastien Helleu2016-12-191-1/+1

* docs: various pages: Use consistent terminology (set-user-ID and set-group-ID)Michael Kerrisk2016-12-091-1/+1
| | | | | | | | | | Use consistent terminology for set-user-ID and set-group-ID bits. There's much inconsistency in the pages. "suid", "set-user-identifier", "setuid". Stick with one terminology, "set-user-ID" and set-grout-ID, as suggested in man-pages(7). Signed-off-by: <mtk.man-pages@gmail.com>
* Place SEE ALSO entries in orderMichael Kerrisk (man-pages)2016-11-291-4/+4
| | | | | | | | | | | | This patch does only the following: * Order SEE ALSO entries first by section name, then alphabetically within section * Adds one or two missing commas in SEE ALSO lists * Removes one or two periods that were (inconsistently) used at the end of SEE ALSO lists. Signed-off-by: Michael Kerrisk <mtk.manpages@gmail.com>
* su, runuser, setpriv: create links between man pagesKarel Zak2016-08-181-1/+6

* su: clean up groups initializationKarel Zak2016-02-151-1/+2
| | | | | | | | | | | | | | | | This patch does not change any su/runuser behaviour, code changes: * don't use huge groups[NGROUPS_MAX]; the array has 256k, but we need it only occasionally when -G/-g specified. * the current code uses groups[0] for -g and the rest for -G, this patch adds 'gid' to remember -g argument to avoid memmove() * add function add_supp_group() to simplify su_main() * add note about -G and -g relation to the man pages (undocumented now) Signed-off-by: Karel Zak <kzak@redhat.com>

* runuser: new command (derived from su(1))Karel Zak2012-09-041-0/+230
This command is based on su(1), the differences: - based on Fedora runuser su(1) patch - not installed with suid rights - allowed for root users only - don't ask for password - uses PAM session, for example: $ cat /etc/pam.d/runuser auth sufficient pam_rootok.so session optional pam_keyinit.so revoke session required pam_limits.so session required pam_unix.so $ cat /etc/pam.d/runuser-l auth include runuser session optional pam_keyinit.so force revoke session include runuser Signed-off-by: Karel Zak <kzak@redhat.com>
