* su/runuser: don't mark --pty as experimental, add it to runuser.1 tooKarel Zak2019-03-041-3/+0Star
| | | | | | | | | * 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>

| | | | | | | | Use the correct macro (I, B) for the font change of one argument, not those that are used for alternating two fonts, like "BR", "IR", "RB", or "RI". Signed-off-by: Bjarni Ingi Gislason <bjarniig@rhi.hi.is>

* docs: various pages: Use consistent terminology (set-user-ID and set-group-ID)Michael Kerrisk2016-12-091-1/+2
| | | | | | | | | | 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)2016-11-291-3/+3
| | | | | | | | | | | | 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: 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>

* su: add --group and --supp-group optionsKarel Zak2012-09-041-0/+6
| | | | | | | | | | | | | | | | | | | These options allow to specify alternative groups. The command su(1) has to be executed by root. The implementation is based on Fedora runuser(1) command. For example: # su --group=kzak --supp-group=uuidd - # id uid=0(root) gid=1000(kzak) groups=0(root),985(uuidd),1000(kzak) non-root user: $ su --group=kzak - su: only root can specify alternative groups Signed-off-by: Karel Zak <kzak@redhat.com>
