_sclp_print_early() has a return value, but misses to sign extend it if called from 64 bit code. This is not really a bug, since currently no caller cares what the return value is. Signed-off-by: NHeiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: NMartin Schwidefsky <schwidefsky@de.ibm.com>

_sclp_print_early() has return value: at present, return 0 for OK, 1 for failure. It returns '%r2', so use 'long' as return value (upper caller can check '%r2' directly).

For C language, it treats array parameter as a pointer, so sizeof for an array parameter is equal to sizeof for a pointer, which causes compiler warning (with allmodconfig by gcc 5): ./arch/s390/include/asm/timex.h: In function 'get_tod_clock_ext': ./arch/s390/include/asm/timex.h:76:32: warning: 'sizeof' on array function parameter 'clk' will return size of 'char *' [-Wsizeof-array-argument] typedef struct { char _[sizeof(clk)]; } addrtype; ^ Can use macro CLOCK_STORE_SIZE instead of all related hard code numbers, which also can avoid this warning. And also add a tab to CLOCK_TICK_RATE definition to match coding styles. [heiko.carstens@de.ibm.com]: Chen's patch actually fixes a bug within the get_tod_clock_ext() inline assembly where we incorrectly tell the compiler that only 8 bytes of memory get changed instead of 16 bytes. This would allow gcc to generate incorrect code. Right now this doesn't seem to be the case. Also slightly changed the patch a bit. - renamed CLOCK_STORE_SIZE to STORE_CLOCK_EXT_SIZE - changed get_tod_clock_ext() to receive a char pointer parameter Signed-off-by: NChen Gang <gang.chen.5i5j@gmail.com> Signed-off-by: NHeiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: NMartin Schwidefsky <schwidefsky@de.ibm.com>

in the cpu time accounting function vtime_account_irq_enter (vtime_account_system) we use a WARN_ON_ONCE(!irqs_disabled()).

Kernel oops caused by invalid parameter at TAPQ instruction: On older systems where the QCI instruction is not available all possible domains are probed via TAPQ instruction. The range for the probe has been extended with the > 16 domain support now leading to a possible specification exception when this instruction is called for probing higher values within the new range. This may happen during insmod and/or ap bus reset only on machines without a QCI instruction (z10, z196, z114), zEC12 and newer systems are not affected. The fix modifies the domain checking function to limit the allowed range if no QCI info is available.

git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace由 Linus Torvalds 提交于
Pull user namespace related fixes from Eric Biederman: "As these are bug fixes almost all of thes changes are marked for backporting to stable. The first change (implicitly adding MNT_NODEV on remount) addresses a regression that was created when security issues with unprivileged remount were closed. I go on to update the remount test to make it easy to detect if this issue reoccurs. Then there are a handful of mount and umount related fixes. Then half of the changes deal with the a recently discovered design bug in the permission checks of gid_map. Unix since the beginning has allowed setting group permissions on files to less than the user and other permissions (aka ---rwx---rwx). As the unix permission checks stop as soon as a group matches, and setgroups allows setting groups that can not later be dropped, results in a situtation where it is possible to legitimately use a group to assign fewer privileges to a process. Which means dropping a group can increase a processes privileges. The fix I have adopted is that gid_map is now no longer writable without privilege unless the new file /proc/self/setgroups has been set to permanently disable setgroups. The bulk of user namespace using applications even the applications using applications using user namespaces without privilege remain unaffected by this change. Unfortunately this ix breaks a couple user space applications, that were relying on the problematic behavior (one of which was tools/selftests/mount/unprivileged-remount-test.c). To hopefully prevent needing a regression fix on top of my security fix I rounded folks who work with the container implementations mostly like to be affected and encouraged them to test the changes. > So far nothing broke on my libvirt-lxc test bed. :-) > Tested with openSUSE 13.2 and libvirt 1.2.9. > Tested-by: Richard Weinberger <richard@nod.at> > Tested on Fedora20 with libvirt 1.2.11, works fine. > Tested-by: Chen Hanxiao <chenhanxiao@cn.fujitsu.com> > Ok, thanks - yes, unprivileged lxc is working fine with your kernels. > Just to be sure I was testing the right thing I also tested using > my unprivileged nsexec testcases, and they failed on setgroup/setgid > as now expected, and succeeded there without your patches. > Tested-by: Serge Hallyn <serge.hallyn@ubuntu.com> > I tested this with Sandstorm.

Dave Hansen reports that commit fb7332a9 ("mmu_gather: move minimal range calculations into generic code") caused a performance problem: "tlb_finish_mmu() goes up about 9x in the profiles (~0.4%->3.6%) and tlb_flush_mmu_free() takes about 3.1% of CPU time with the patch applied, but does not show up at all on the commit before" and the reason is that Will moved the test for whether we need to flush from tlb_flush_mmu() into tlb_flush_mmu_tlbonly(). But that meant that tlb_flush_mmu_free() basically lost that check. Move it back into tlb_flush_mmu() where it belongs, so that it covers both tlb_flush_mmu_tlbonly() _and_ tlb_flush_mmu_free().
