| | | | | | | | | | | | | | | | | | | | | | | | | | There is a segfault in do_shm_global() when ipc_shm_get_info() return 0 and ipc_shm_free_info() is called. When no shm id is found, the memory allocated in shmds by ipc_shm_get_info() is already free when ipc_shm_free_info() is called.

* | lscpu: correct the Virtualization type on Xen DomU PV guestDongli Zhang2016-03-221-2/+30
|/ | | | | | | | | | | | | | | | | | | | | | | Nowadays, most Intel CPUs have "cpuid faulting" available which could trap the execution of "cpuid" instruction when CPL>0 with GP fault. Thus, "cpuid" instruction could trap to Xen hypervisor on the paravirtualized PV guest on most servers today, except on old CPUs prior to 2011. On CPU after 2011, Xen will put "XenVMMXenVMM" on both HVM and PV guests, which could have lscpu command erroneously classify the guest as type "full". The current lscpu command, which is based on "cpuid" instruction, still assumes that it will not cause the trap to Xen hypervisor on Xen PV guest and uses /proc/xen to identify whether it's running on PV DomU or not. To identify this kind of information under the help of /sys/hypervisor/properties/features would be more accurate for the CPU nowadays. The bit 5 (XENFEAT_mmu_pt_update_preserve_ad) of the features will be set only when it's running on Xen PV domain. The combo of bit 3 and 8 (XENFEAT_supervisor_mode_kernel and XENFEAT_hvm_callback_vector) will be set simultaneously only when it's running on Xen PVH domain.

* | ipcs: consolidate output header printingRuediger Meier2016-03-211-5/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | Print a warning (instead of header) if --limits fails, like we did it in past (2.20.1) and like we are still doing for --summary. Note in past we were printing the same message like for --summary "kernel not configured for ...", but actually this message is not really correct. This patch simply consolidates the current behavior. Probably we should refactor it regarding warnings (stderr) and exit codes. Signed-off-by: Ruediger Meier <ruediger.meier@ga-group.nl>
* | ipcs: --shmems, upward/backward compatibilityRuediger Meier2016-03-181-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | Re-add backward compatibility which got lost in 058e8154. Initializing unknown struct members to 0xdead is similar to the fallback. For upward compatibility ignore columns > 16 but not the whole line (in case the kernel would add more columns in future).

| | | | | | | | | | | | | | | | | | | | | | | | | | We want to parse 16 columns _per_row_ without mixing them up. The existing code is unsafe for more or less columns and could even run into endless loops. This patch assures that we parse row-wise and really skip lines with columns != 16. Probably somehow we could have also done this with fscanf() only. Using fgets() additionally makes the code more easy to read and to improve later.

* | swapon: rewrite control struct usageKarel Zak2016-03-182-118/+184
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old version has been pretty broken... the most important is to keep swap options specified on command line as read-only template. For example if we call "swapon --all" then we cannot modify the global options for each fstab swap entry. The another story has been control struct modification due to device reinitialization etc. This patch splits all to: * struct swapon_control; top-level struct with command line options * struct swap_device; this is device specific and never globally maintained by swapon_control. * struct swap_prop; used as global read-only template swap options and per device swap options (when parse fstab).

* | | swapon: fix discard=pages docsRichard Yao2016-03-141-1/+1
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The documentation for discard=pages is ambiguous in that it could be interpreted to mean either that the pages are discarded immediately after being freed or that the pages are discarded immediately before being reused by a write. Both implementations would satisfy the statement "discard freed swap pages before they are avaliable for reuse", but the kernel does the former. Doing a discard operation (which is non-queued on SATA drives before SATA 3.1) before a write operation to the same sector is pointless unless using, pre-SATA 3.1 drives, where discard is detrimental because ATA TRIM is a non-queued command. Anyone who wants discard operations on swap and interprets the man page as describing the incorrect behavior would opt for discard=once over discard, when discard provides the behavior of both discard=once and discard=pages, which is what they likely want. Lets make a small change to the documentation to clarify the behavior. Signed-off-by: Richard Yao <ryao@gentoo.org>
