2017-07-06setpriv: dump inheritable capability setPatrick Steinhardt
The setpriv executable from util-linux also dumps out information on the different capability sets known by the kernel. By default, these are the inheritable capabilities, bounding capabilities and (not yet released) the ambient capabilities, which have been introduced with Linux 4.3. This patch introduces the ability to dump the set of inheritable capabilities. By default, setpriv(1) identifies capabilities by their human-readable name, for example 'net_admin'. For unknown capabilities, though, it does instead use the capability's value, for example 'cap_12', which is equivalent to 'net_admin'. As there is no kernel interface to retrieve capability names by their index, we have to declare these ourselves, which adds to setpriv's size. To counteract, using the human-readble name has been made configurable. The following sizes are with the 'FEATURE_SETPRIV_CAPABILITY_NAMES' enabled: function old new delta .rodata 145969 146405 +436 setpriv_main 467 842 +375 capabilities - 304 +304 And with 'FEATURE_SETPRIV_CAPABILITY_NAMES' disabled: function old new delta setpriv_main 467 838 +371 .rodata 145969 146101 +132 Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2017-07-04setpriv: dump user and group infoDenys Vlasenko
setpriv from util-linux has an option to dump the current state regarding privilege settings via '--dump'. It prints out information on the real and effective user and group IDs, supplementary groups, the no-new-privs flag, the capability sets as well as secure bits. This patch is the start of supporting this mode. To make introduction of the '--dump' easier to reason about, its introduction has been split into multiple patches. This particular one introduces the ability to print out user and group information of the current process. function old new delta setpriv_main 89 322 +233 getresuid - 41 +41 getresgid - 41 +41 static.setpriv_longopts 22 29 +7 packed_usage 31675 31669 -6 ------------------------------------------------------------------------------ (add/remove: 4/0 grow/shrink: 2/1 up/down: 322/-6) Total: 316 bytes Patch by Patrick Steinhardt <ps@pks.im> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2017-07-04setpriv: prepare option parsing logic for additional optsPatrick Steinhardt
The current option parsing logic of setpriv only supports the case where we want to execute a sub-program and have at most one argument. Refactor handling of options to solve these shortcomings to make it easy to support 'setpriv --dump', which does not accept any additional arguments, as well as the case where additional options are passed to setpriv. This is done by handling 'argc' ourselves, throwing an error when no program is specified, as well as introducing an enum for the different option bitmasks.

2017-07-04setpriv: do not process remaining argsPatrick Steinhardt
By default, the 'getopt32' call will continue parsing the command line even after hitting a non-option string. But in setpriv, this should be avoided, as all parameters following the initial non-option argument are in fact arguments to the binary that is to be executed by setpriv. Otherwise, calling e.g. 'busybox setpriv ls -l' would result in an error due to the unknown parameter "-l". Fix the issue by passing "+" as the first character in the options string. This will cause 'getopt32' to stop processing after hitting the first non-option. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
