On s390, we've got to make sure to hold the IPTE lock while accessing logical memory. So let's add an ioctl for reading and writing logical memory to provide this feature for userspace, too. The maximum transfer size of this call is limited to 64kB to prevent that the guest can trigger huge copy_from/to_user transfers. QEMU currently only requests up to one or two pages so far, so 16*4kB seems to be a reasonable limit here.

Access register mode is one of the modes that control dynamic address translation. In this mode the address space is specified by values of the access registers. The effective address-space-control element is obtained from the result of the access register translation. See the "Access-Register Introduction" section of the chapter 5 "Program Execution" in "Principles of Operations" for more details.

During dynamic address translation the get_vcpu_asce() function can be invoked several times. It's ok for usual modes, but will be slow if CPUs are in AR mode.

The kvm_s390_check_low_addr_protection() function is used only with real addresses. According to the POP (the "Low-Address Protection" paragraph in chapter 3), if the effective address is real or absolute, the low-address protection procedure should raise a PROTECTION exception only when the low-address protection is enabled in the control register 0 and the address is low. This patch removes ASCE checks from the function and renames it to better reflect its behavior.

Define and allocate space for both the host and guest views of the vector registers for a given vcpu. The 32 vector registers occupy 128 bits each (512 bytes total), but architecturally are paired with 512 additional bytes of reserved space for future expansion. The kvm_sync_regs structs containing the registers are union'ed with 1024 bytes of padding in the common kvm_run struct. The addition of 1024 bytes of new register information clearly exceeds the existing union, so an expansion of that padding is required. When changing environments, we need to appropriately save and restore the vector registers viewed by both the host and guest, into and out of the sync_regs space. The floating point registers overlay the upper half of vector registers 0-15, so there's a bit of data duplication here that needs to be carefully avoided.

Besides cpuid and ibc initialization, facility list assignment takes place during the setup step as well. The model setup has been pulled to the begin of vcpu setup to allow kvm facility tests.

When the SIE exited by a DAT access exceptions which we can not resolve, the guest tried to access a page which is out of bounds and can not be paged-in. In this case we have to signal the bad access by injecting an address exception. However, address exceptions are either suppressing or terminating, i.e. the PSW has to point to the next instruction when the exception is delivered. Since the originating DAT access exception is nullifying, the PSW still points to the offending instruction instead, so we've got to forward the PSW to the next instruction. Having fixed this issue, we can now also enable the TPROT interpretation facility again which had been disabled because of this problem.

When certain program exceptions (e.g. DAT access exceptions) occur, the current instruction has to be nullified, i.e. the old PSW that gets written into the low-core has to point to the beginning of the instruction again, and not to the beginning of the next instruction. Thus we have to rewind the PSW before writing it into the low-core. The list of nullifying exceptions can be found in the POP, chapter 6, figure 6-1 ("Interruption Action").

The reinjection of an I/O interrupt can fail if the list is at the limit and between the dequeue and the reinjection, another I/O interrupt is injected (e.g. if user space floods kvm with I/O interrupts). This patch avoids this memory leak and returns -EFAULT in this special case. This error is not recoverable, so let's fail hard. This can later be avoided by not dequeuing the interrupt but working directly on the locked list.

Most facility related decisions in KVM have to take into account: - the facilities offered by the underlying run container (LPAR/VM) - the facilities supported by the KVM code itself - the facilities requested by a guest VM This patch adds the KVM driver requested facilities to the test routine. It additionally renames struct s390_model_fac to kvm_s390_fac and its field names to be more meaningful. The semantics of the facilities stored in the KVM architecture structure is changed. The address arch.model.fac->list now points to the guest facility list and arch.model.fac->mask points to the KVM facility mask. This patch fixes the behaviour of KVM for some facilities for guests that ignore the guest visible facility bits, e.g. guests could use transactional memory intructions on hosts supporting them even if the chosen cpu model would not offer them. The userspace interface is not affected by this change. Signed-off-by: NMichael Mueller <mimu@linux.vnet.ibm.com> Signed-off-by: NChristian Borntraeger <borntraeger@de.ibm.com>

.. after extensive statistical analysis of my G+ polling, I've come to the inescapable conclusion that internet polls are bad. Big surprise. But "Hurr durr I'ma sheep" trounced "I like online polls" by a 62-to-38% margin, in a poll that people weren't even supposed to participate in. Who can argue with solid numbers like that? 5,796 votes from people who can't even follow the most basic directions? In contrast, "v4.0" beat out "v3.20" by a slimmer margin of 56-to-44%, but with a total of 29,110 votes right now. Now, arguably, that vote spread is only about 3,200 votes, which is less than the almost six thousand votes that the "please ignore" poll got, so it could be considered noise. But hey, I asked, so I'll honor the votes.

I've noticed significant locking contention in memory reclaimer around sb_lock inside grab_super_passive(). Grab_super_passive() is called from two places: in icache/dcache shrinkers (function super_cache_scan) and from writeback (function __writeback_inodes_wb). Both are required for progress in memory allocator. Grab_super_passive() acquires sb_lock to increment sb->s_count and check sb->s_instances. It seems sb->s_umount locked for read is enough here: super-block deactivation always runs under sb->s_umount locked for write. Protecting super-block itself isn't a problem: in super_cache_scan() sb is protected by shrinker_rwsem: it cannot be freed if its slab shrinkers are still active. Inside writeback super-block comes from inode from bdi writeback list under wb->list_lock. This patch removes locking sb_lock and checks s_instances under s_umount: generic_shutdown_super() unlinks it under sb->s_umount locked for write. New variant is called trylock_super() and since it only locks semaphore, callers must call up_read(&sb->s_umount) instead of drop_super(sb) when they're done.

Convert the following where appropriate: (1) S_ISLNK(dentry->d_inode) to d_is_symlink(dentry). (2) S_ISREG(dentry->d_inode) to d_is_reg(dentry). (3) S_ISDIR(dentry->d_inode) to d_is_dir(dentry). This is actually more complicated than it appears as some calls should be converted to d_can_lookup() instead. The difference is whether the directory in question is a real dir with a ->lookup op or whether it's a fake dir with a ->d_automount op. In some circumstances, we can subsume checks for dentry->d_inode not being NULL into this, provided we the code isn't in a filesystem that expects d_inode to be NULL if the dirent really *is* negative (ie. if we're going to use d_inode() rather than d_backing_inode() to get the inode pointer). Note that the dentry type field may be set to something other than DCACHE_MISS_TYPE when d_inode is NULL in the case of unionmount, where the VFS manages the fall-through from a negative dentry to a lower layer. In such a case, the dentry type of the negative union dentry is set to the same as the type of the lower dentry. However, if you know d_inode is not NULL at the call site, then you can use the d_is_xxx() functions even in a filesystem. There is one further complication: a 0,0 chardev dentry may be labelled DCACHE_WHITEOUT_TYPE rather than DCACHE_SPECIAL_TYPE. Strictly, this was intended for special directory entry types that don't have attached inodes. The following perl+coccinelle script was used: use strict; my @callers; open($fd, 'git grep -l \'S_IS[A-Z].*->d_inode\' |') || die "Can't grep for S_ISDIR and co. callers"; @callers = <$fd>; close($fd); unless (@callers) { print "No matches\n"; exit(0); } my @cocci = ( '@@', 'expression E;', '@@', '', '- S_ISLNK(E->d_inode->i_mode)', '+ d_is_symlink(E)', '', '@@', 'expression E;', '@@', '', '- S_ISDIR(E->d_inode->i_mode)', '+ d_is_dir(E)', '', '@@', 'expression E;', '@@', '', '- S_ISREG(E->d_inode->i_mode)', '+ d_is_reg(E)' ); my $coccifile = "tmp.sp.cocci"; open($fd, ">$coccifile") || die $coccifile; print($fd "$_\n") || die $coccifile foreach (@cocci); close($fd); foreach my $file (@callers) { chomp $file; print "Processing ", $file, "\n"; system("spatch", "--sp-file", $coccifile, $file, "--in-place", "--no-show-diff") == 0 || die "spatch failed"; } [AV: overlayfs parts skipped] Signed-off-by: NDavid Howells <dhowells@redhat.com> Signed-off-by: NAl Viro <viro@zeniv.linux.org.uk>
