* ipcs: add --bytes size output optionSami Kerola2012-12-192-1/+9
| | | | | | | | This makes the command being a little closer standard compliant. See IEEE Std 1003.1 referral link below for more information. References: http://pubs.opengroup.org/onlinepubs/009696799/utilities/ipcs.html Signed-off-by: Sami Kerola <kerolasa@iki.fi>
* ipcs: add --human readable size conversion optionSami Kerola2012-12-194-34/+106
| | | | | | | | | Introduces new function ipc_print_size() which will call size_to_human_string(), and handles the occasional '([k]bytes)' printing if default size format is requested. Reviewed-by: Karel Zak <kzak@redhat.com> Signed-off-by: Sami Kerola <kerolasa@iki.fi>

| | | | | | | The commit 7ae8b469adda598fda28e4ea647d47905b43e172 added option --bytes, not the initial proposal which was changed after maillist discussion. Signed-off-by: Sami Kerola <kerolasa@iki.fi>

| | | | | | | | | | | | | | | | | | | | | | $ mount /root/.ssh/../../dev/sda2 mount: only root can mount UUID=17bc65ec-4125-4e7c-8a7d-e2795064c736 on /boot this is too promiscuous. It seems better to ignore on command line specified paths which are not resolve-able for non-root users. Fixed version: $ mount /root/.ssh/../../dev/sda2 mount: /root/.ssh/../../dev/sda2: Permission denied $ mount /dev/sda2 mount: only root can mount UUID=17bc65ec-4125-4e7c-8a7d-e2795064c736 on /boot Note that this bug has no relation to mount(2) permissions evaluation in suid mode. The way how non-root user specifies paths on command line is completely irrelevant for comparison with fstab entries. Signed-off-by: Karel Zak <kzak@redhat.com>

| | | | | | | | | In the umount --recursive we follow entries from mountinfo, but the entries maybe already obsolete.

* lscpu: Fix issue found on CPU hot-removeToshi Kani2012-11-121-22/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | read_basicinfo() relies on sysfs cpu directories "/sys/devices/system/cpu/cpu%d" with assumption that cpu logical number %d is always sequentially assigned for all CPUs. However, this assumption is not correct with CPU hot-remove operation since it removes a target sysfs cpu directory after it is ejected. As a result, lscpu may not recognize all CPUs. The issue can be easily reproduced on KVM or VirtualBox, which supports CPU eject operation, as follows. 1) The system has 4 CPUs $ lscpu -a -e CPU NODE SOCKET CORE L1d:L1i:L2 ONLINE 0 0 0 0 0:0:0 yes 1 0 1 1 1:1:1 yes 2 0 2 2 2:2:2 yes 3 0 3 3 3:3:3 yes 2) Eject cpu2 # echo 1 > /sys/bus/acpi/devices/LNXCPU:02/eject 3) lscpu no longer recognizes cpu3 after cpu2 is ejected $ lscpu -a -e CPU NODE SOCKET CORE L1d:L1i:L2 ONLINE 0 0 0 0 0:0:0 yes 1 0 1 1 1:1:1 yes The following changes are made to address this issue. - Use maxcpus to allocate and parse bitmaps. - Set desc->ncpu from cpu/present, which includes both on-line and off-line CPUs. - Add is_cpu_present() to check if a CPU is present. Ejected CPUs are not present.
