| | | | | | | Don't use list_speeds() as non-return function, it seems better to keep main() code consistent. Signed-off-by: Karel Zak <kzak@redhat.com>

* agetty: remove dead DO_DEVFS_FIDDLING code segmentSami Kerola2017-08-051-39/+0Star

* bash-completion: look for look completionsSami Kerola2017-08-051-3/+10
| | | | | | | | | | The look(1) uses positional arguments, where first one is a word from dictionary. It is reasonable to assume most of the time people search from system word lists so propose completions from there. The second argument is a dictionary file, that might invalidate the first input but that only happens to users who have an idea what the want without bash-completion.

* vipw: use explicit_bzero() to clear buffer after copySami Kerola2017-08-051-0/+3
| | | | | | | | | | This should make leaking end of /etc/shadow file more unlikely. Notice that there is now way to tell to editors they should ensure none it does not leak any buffers, drop cores, and so on, when editing sensitive data. In short this change is addressing the issue only partially. Signed-off-by: Sami Kerola <kerolasa@iki.fi>

* libblkid: add support for UBI superblockRafał Miłecki2017-08-036-0/+59
| | | | | | | | | | | | | | | | | | UBI is a volume management system that can be used on a raw flash partition for providing multiple logical volumes. Detecting UBI superblock may be useful for tools wanting to simplify or automate attaching UBI. Please note it's not directly related to the ubifs support which is just a filesystem working on top of UBI volume. In other words: UBI can be used on MTD partition (e.g. /dev/mtdblock0) while ubifs can be used on UBI volume (e.g. /dev/ubi0_0). This patch adds simple code reading UBI version and unique number and setting it in the blkid_probe. Signed-off-by: Rafał Miłecki <rafal@milecki.pl>

The patch also minimize number of HAVE_...NCURSES_H macros in config.h. We don't need to check for ncurses.h if ncurses/ncurses.h is available.

* setpriv: document accepted formats for naming capsPatrick Steinhardt2017-08-011-1/+6
| | | | | | | | | | | | Since commit fbd15c4d4 (setpriv: support setting unnamed capabilities, 2017-07-17), it is possible to name capabilities not only by name, but also by their index. While using the human-readable name is usually recommended, using the index may be required in case new capabilities have been introduced to the kernel for which we have no name yet. The newly introduce format format is not documented inside of setpriv(1), though, which is being fixed in this commit. Signed-off-by: Patrick Steinhardt <ps@pks.im>

* hwclock: fix unimplemented ioctl testJ William Piggott2017-07-311-2/+2
| | | | | | | | | The rtc driver has not returned EINVAL for unimplemented ioctls since v2.5.8 in 2002. However, it does return it for other errors; making the current test potentially problematic. Since 9f3d0fc util-linux assumes kernel >= 2.6.0 so remove EINVAL as an ioctl test. Signed-off-by: J William Piggott <elseifthen@gmx.com>

* hwclock: squash custom errno stringsJ William Piggott2017-07-311-26/+6Star
| | | | | | | | | | | | | | | | | | | | | | | | | hwclock previously used printf for custom errno messages. Later they were converted to use warn(), but were not squashed. One of the reasons for warn and errno is to avoid making translators deal with a multitude custom strings. Also the custom strings are incorrect: hwclock --hctosys hwclock: Must be superuser to set system clock. Unable to set system clock. We do not know what the system permissions are set to. The correct response is to simply say permission was denied; as the default errno string does. The second line is redundant and just adds noise the code and to logs.

* build: use --runstatedir instead of --localstatedirAndreas Henriksson2017-07-318-17/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The util-linux code was previously aligned to use @localstatedir@ and the util-linux build system was set to override the default to use /run. Current GNU Coding Standards introduced the @runstatedir@ variable for this purpose. Lets use that instead. The GNU default for @runstatedir@ is ${localstatedir}/run so util-linux still override the default to be /run to preserve the status quo from before. The only difference is that you'll now pass --runstatedir to override the location on the command line instead of --localstatedir. (FWIW, Debhelper in compat 11 will automatically start passing --runstatedir=/run to all autotools configured builds. It already passes --localstatedir=/var (to avoid it ending up with the GNU default /usr/local/var) which breaks the util-linux build system code that tries to default it to /run. This change will thus allow util-linux and debhelper to work better together and avoid the need for a package-specific override.)

| | | | | | | | | | | | | | | The default (for historical reasons) is to use dialog driven partitioning. It's possible to avoid dialogs by fdisk_partition template for fdisk_add_partition(). Unfortunately in some case (mostly DOS driver) it's not enough, because we need to distinguish between logical and primary partitions. If we know that dialogs are unwanted then we can default to primary partition, etc. This function simplify semantic of the library for non-interactive programs.

* setpriv: support setting unnamed capabilitiesPatrick Steinhardt2017-07-181-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When setting capabilities, we accept human readable names like for example `sys_rawio` or `net_admin`. To do so the translation between the capability name and its in-kernel index, we rely on the function `capng_name_to_capability`. When the function does not know the named capability, it will return an error value and we abort setting the capability. This relies upon the ability of libcap to know all capabilities inside of the kernel. But actually, it is possible that new capabilities are introduced inside of the Linux kernel which are not recognized yet by the library. When dumping these unknown capabilities, libcap will simply return a string like "cap_38", that is it will append the capability's in-kernel index to the prefix "cap_". This may lead a user to also think that "cap_38" may be passed to the switches "--inh-caps" or "--ambient-caps", which is unfortunately not the case. We can do better here by instead accepting strings in the form of "cap_N". To do so, we can simply rely on the fact that capability indices are steadily increasing and that the highest index known to the kernel is stored inside of the kernel's procfs, made readily available by our function `real_cap_last_cap()`. So in case libcap does not know a capability name, we can simply parse the string and, if it is in the correct format, check whether the detected index is between 0 and the highest capability index. If so, we can treat it as a valid capability string and apply it. Signed-off-by: Patrick Steinhardt <ps@pks.im>
