* textual: grammarize and harmonize the stat error messageBenno Schulenberg2015-02-027-8/+8
| | | | | | | | | The message "stat failed %s" seems to say that stat() failed to do something, or failed to pass a test, but of course it means that the statting of something failed. So say so. Also make two very similar messages equal to this one. Signed-off-by: Benno Schulenberg <bensberg@justemail.net>

* libmount: revert "read mtab on remount" ideaKarel Zak2015-01-161-9/+8Star
| | | | | | | | | | | | | | It's backwardly incompatible nonsense to prefer mtab on remount. mount -o remount /foo has to read mount options from fstab otherwise the remount has no effect. (The ideal solution would be to read both mtab, then modify the options according to fstab -- but for now more important is to be backwardly compatible.)

| * hwclock: remove automatic ISA fallbackJ William Piggott2015-01-141-7/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old behavior when hwclock was unable to access the rtc device was to fallback to direct ISA I/O. This was sometimes allowing two processes to access the Hardware Clock at the same time and hanging the system. This is the reason the rtc device driver only allows one process to open it. Now hwclock defaults to using the rtc device and only uses direct ISA when that option is given. Signed-off-by: J William Piggott <elseifthen@gmx.com>

* hwclock: Incorrect UTC defaultsJWP2015-01-091-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hwclock's default timescale was changed to UTC in: commit 7894bf0f08740f75610990a2ba76af7a7cbce61e Date: Mon Feb 21 13:27:07 2011 +0000 This change was incomplete. With no /etc/adjtime file the current behavior is: hwclock --utc --adjust #Creates a UTC file. hwclock --localtime --adjust #File is not created. That is the opposite of what UTC default should do. With this patch the behavior is: hwclock --utc --adjust #File is not created. hwclock --localtime --adjust #Creates a LOCAL file. 'Creates a xxxx file' means: An /etc/adjtime file is created with zero for all parameters except the Hardware Clock's timescale field, which is set to the value indicated by xxxx. The second item missed in the patch was a test in the save_adjtime() function that defaults to LOCAL. Theoretically we cannot get to the save function without having a value set for adjtime.local_utc, but the test is there so it needs be correct. Signed-off-by: J William Piggott <elseifthen@gmx.com>
* hwclock: enable --directisa for x86_64JWP2015-01-091-4/+5

* nsenter: add --preserve-credentials and cleanup setgroups() usageKarel Zak2015-01-092-6/+25
| | | | | | | | | | | | | The new option --preserve-credentials completely disables all operations related to UIGs and GIDs. The patch also calls setgroups() before we enter user namespace (so root can always clear their groups) and after we enter user namespace (to detect /proc/self/setgroups "deny"). If both fail then nsenter complains. Acked-by: "Eric W. Biederman" <ebiederm@xmission.com> Signed-off-by: Karel Zak <kzak@redhat.com>
* nsenter: keep semantic consistentKarel Zak2015-01-091-0/+9
| | | | | | | | | | | | | | | The current nseneter behavior is inconsistent and depends on way how namespace is specified on command line # nsenter --user vs. # nseneter --user=filename if the namespace is specified by <filename> than nsenter does not do additinal setting and actions (e.g. does not call setgroups, setuid). This is bug. Signed-off-by: Karel Zak <kzak@redhat.com>
* unshare: add --setgroups=deny|allowKarel Zak2015-01-092-6/+65
| | | | | | | | | | | | | | Since Linux 3.19 the file /proc/self/setgroups controls setgroups(2) syscall usage in user namespaces. This patch provides command line knob for this feature. The new --setgroups does not automatically implies --user to avoid complexity, it's user's responsibility to use it in right context. The exception is --map-root-user which is mutually exclusive to --setgroups=allow. CC: "Eric W. Biederman" <ebiederm@xmission.com> Signed-off-by: Karel Zak <kzak@redhat.com>
* unshare: Fix --map-root-user to work on new kernelsEric W. Biederman2015-01-091-0/+19
| | | | | | | | | | | | | | | In rare cases droping groups with setgroups(0, NULL) is an operation that can grant a user additional privileges. User namespaces were allwoing that operation to unprivileged users and that had to be fixed. Update unshare --map-root-user to disable the setgroups operation before setting the gid_map. This is needed as after the security fix gid_map is restricted to privileged users unless setgroups has been disabled. Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com>

| | | | | | | | | | | | | | | | This change fixes all shadow declarations. The worth while to mention fix is with libfdisk sun geometry. It comes from bitops.h cpu_to_be16 macro that further expands from include/bits/byteswap.h that has the shadowing. libfdisk/src/sun.c:961:173: warning: declaration of '__v' shadows a previous local [-Wshadow] libfdisk/src/sun.c:961:69: warning: shadowed declaration is here [-Wshadow] libfdisk/src/sun.c:961:178: warning: declaration of '__x' shadows a previous local [-Wshadow] libfdisk/src/sun.c:961:74: warning: shadowed declaration is here [-Wshadow] That could have caused earlier some unexpected results.
