Commit f3bbac32 ("ext4: deal with legacy signed xattr name hash values") added a hashing function for the legacy case of having the xattr hash calculated using a signed 'char' type. It left the unsigned case alone, since it's all implicitly handled by the '-funsigned-char' compiler option. However, there's been some noise about back-porting it all into stable kernels that lack the '-funsigned-char', so let's just make that at least possible by making the whole 'this uses unsigned char' very explicit in the code itself. Whether such a back-port is really warranted or not, I'll leave to others, but at least together with this change it is technically sensible. Also, add a 'pr_warn_once()' for reporting the "hey, signedness for this hash calculation has changed" issue. Hopefully it never triggers except for that xfstests generic/454 test-case, but even if it does it's just good information to have. If for no other reason than "we can remove the legacy signed hash code entirely if nobody ever sees the message any more".

When serializing and deserializing kvm_sregs, attributes of the segment descriptors are stored by user space. For unusable segments, vmx_segment_access_rights skips all attributes and sets them to 0. This means we zero out the DPL (Descriptor Privilege Level) for unusable entries. Unusable segments are - contrary to their name - usable in 64bit mode and are used by guests to for example create a linear map through the NULL selector. VMENTER checks if SS.DPL is correct depending on the CS segment type. For types 9 (Execute Only) and 11 (Execute Read), CS.DPL must be equal to SS.DPL [1]. We have seen real world guests setting CS to a usable segment with DPL=3 and SS to an unusable segment with DPL=3. Once we go through an sregs get/set cycle, SS.DPL turns to 0. This causes the virtual machine to crash reproducibly. This commit changes the attribute logic to always preserve attributes for unusable segments. According to [2] SS.DPL is always saved on VM exits, regardless of the unusable bit so user space applications should have saved the information on serialization correctly. [3] specifies that besides SS.DPL the rest of the attributes of the descriptors are undefined after VM entry if unusable bit is set. So, there should be no harm in setting them all to the previous state.

Commit b2b0a5e9 switched from generic_writepages() to filemap_fdatawrite_wbc() in gfs2_ail1_start_one() on the path to replacing ->writepage() with ->writepages() and eventually eliminating the former. Function gfs2_ail1_start_one() is called from gfs2_log_flush(), our main function for flushing the filesystem log. Unfortunately, at least as implemented today, ->writepage() and ->writepages() are entirely different operations for journaled data inodes: while the former creates and submits transactions covering the data to be written, the latter flushes dirty buffers out to disk. With gfs2_ail1_start_one() now calling ->writepages(), we end up creating filesystem transactions while we are in the course of a log flush, which immediately deadlocks on the sdp->sd_log_flush_lock semaphore. Work around that by going back to how things used to work before commit b2b0a5e9 for now; figuring out a superior solution will take time we don't have available right now. However ... Since the removal of generic_writepages() is imminent, open-code it here. We're already inside a blk_start_plug() ... blk_finish_plug() section here, so skip that part of the original generic_writepages(). This reverts commit b2b0a5e9.

Pull another io_uring fix from Jens Axboe: "Just a single fix for a regression that happened in this release due to a poll change. Normally I would've just deferred it to next week, but since the original fix got picked up by stable, I think it's better to just send this one off separately. The issue is around the poll race fix, and how it mistakenly also got applied to multishot polling. Those don't need the race fix, and we should not be doing any reissues for that case. Exhaustive test cases were written and committed to the liburing regression suite for the reported issue, and additions for similar issues" * tag 'io_uring-6.2-2023-01-21' of git://git.kernel.dk/linux: io_uring/poll: don't reissue in case of poll race on multishot request

We potentially have old hashes of the xattr names generated on systems with signed 'char' types. Now that everybody uses '-funsigned-char', those hashes will no longer match. This only happens if you use xattrs names that have the high bit set, which probably doesn't happen in practice, but the xfstest generic/454 shows it. Instead of adding a new "signed xattr hash filesystem" bit and having to deal with all the possible combinations, just calculate the hash both ways if the first one fails, and always generate new hashes with the proper unsigned char version.

To save the vgic LPI pending state with GICv4.1, the VPEs must all be unmapped from the ITSs so that the sGIC caches can be flushed. The opposite is done once the state is saved. This is all done by using the activate/deactivate irqdomain callbacks directly from the vgic code. Crutially, this is done without holding the irqdesc lock for the interrupts that represent the VPE. And these callbacks are changing the state of the irqdesc. What could possibly go wrong? If a doorbell fires while we are messing with the irqdesc state, it will acquire the lock and change the interrupt state concurrently. Since we don't hole the lock, curruption occurs in on the interrupt state. Oh well. While acquiring the lock would fix this (and this was Shanker's initial approach), this is still a layering violation we could do without. A better approach is actually to free the VPE interrupt, do what we have to do, and re-request it. It is more work, but this usually happens only once in the lifetime of the VM and we don't really care about this sort of overhead.

A previous commit fixed a poll race that can occur, but it's only applicable for multishot requests. For a multishot request, we can safely ignore a spurious wakeup, as we never leave the waitqueue to begin with. A blunt reissue of a multishot armed request can cause us to leak a buffer, if they are ring provided. While this seems like a bug in itself, it's not really defined behavior to reissue a multishot request directly. It's less efficient to do so as well, and not required to rearm anything like it is for singleshot poll requests.

Pull io_uring fixes from Jens Axboe: "Fixes for the MSG_RING opcode. Nothing really major: - Fix an overflow missing serialization around posting CQEs to the target ring (me) - Disable MSG_RING on a ring that isn't enabled yet. There's nothing really wrong with allowing it, but 1) it's somewhat odd as nobody can receive them yet, and 2) it means that using the right delivery mechanism might change. As nobody should be sending CQEs to a ring that isn't enabled yet, let's just disable it (Pavel) - Tweak to when we decide to post remotely or not for MSG_RING (Pavel)" * tag 'io_uring-6.2-2023-01-20' of git://git.kernel.dk/linux: io_uring/msg_ring: fix remote queue to disabled ring io_uring/msg_ring: fix flagging remote execution io_uring/msg_ring: fix missing lock on overflow for IOPOLL io_uring/msg_ring: move double lock/unlock helpers higher up
