+Subject: fuse: flush extending writes
+
+From: Miklos Szeredi <mszeredi@redhat.com>
+
+commit 59bda8ecee2ffc6a602b7bf2b9e43ca669cdbdcd upstream.
+
+Callers of fuse_writeback_range() assume that the file is ready for
+modification by the server in the supplied byte range after the call
+returns.
+
+If there's a write that extends the file beyond the end of the supplied
+range, then the file needs to be extended to at least the end of the range,
+but currently that's not done.
+
+There are at least two cases where this can cause problems:
+
+ - copy_file_range() will return short count if the file is not extended
+ up to end of the source range.
+
+ - FALLOC_FL_ZERO_RANGE | FALLOC_FL_KEEP_SIZE will not extend the file,
+ hence the region may not be fully allocated.
+
+Fix by flushing writes from the start of the range up to the end of the
+file. This could be optimized if the writes are non-extending, etc, but
+it's probably not worth the trouble.
+
+Fixes: a2bc92362941 ("fuse: fix copy_file_range() in the writeback case")
+Fixes: 6b1bdb56b17c ("fuse: allow fallocate(FALLOC_FL_ZERO_RANGE)")

+Subject: fuse: truncate pagecache on atomic_o_trunc
+
+From: Miklos Szeredi <mszeredi@redhat.com>
+
+commit 76224355db7570cbe6b6f75c8929a1558828dd55 upstream.
+
+fuse_finish_open() will be called with FUSE_NOWRITE in case of atomic
+O_TRUNC. This can deadlock with fuse_wait_on_page_writeback() in
+fuse_launder_page() triggered by invalidate_inode_pages2().
+
+Fix by replacing invalidate_inode_pages2() in fuse_finish_open() with a
+truncate_pagecache() call. This makes sense regardless of FOPEN_KEEP_CACHE
+or fc->writeback cache, so do it unconditionally.

+Subject: IMA: remove the dependency on CRYPTO_MD5
+
+From: THOBY Simon <Simon.THOBY@viveris.fr>
+
+commit 8510505d55e194d3f6c9644c9f9d12c4f6b0395a upstream.
+
+MD5 is a weak digest algorithm that shouldn't be used for cryptographic
+operation. It hinders the efficiency of a patch set that aims to limit
+the digests allowed for the extended file attribute namely security.ima.
+MD5 is no longer a requirement for IMA, nor should it be used there.
+
+The sole place where we still use the MD5 algorithm inside IMA is setting
+the ima_hash algorithm to MD5, if the user supplies 'ima_hash=md5'
+parameter on the command line. With commit ab60368ab6a4 ("ima: Fallback
+to the builtin hash algorithm"), setting "ima_hash=md5" fails gracefully
+when CRYPTO_MD5 is not set:
+ ima: Can not allocate md5 (reason: -2)
+ ima: Allocating md5 failed, going to use default hash algorithm sha256
+
+Remove the CRYPTO_MD5 dependency for IMA.

+Subject: KVM: nVMX: Unconditionally clear nested.pi_pending on nested VM-Enter
+
+From: Sean Christopherson <seanjc@google.com>
+
+commit f7782bb8d818d8f47c26b22079db10599922787a upstream.
+
+Clear nested.pi_pending on nested VM-Enter even if L2 will run without
+posted interrupts enabled. If nested.pi_pending is left set from a
+previous L2, vmx_complete_nested_posted_interrupt() will pick up the
+stale flag and exit to userspace with an "internal emulation error" due
+the new L2 not having a valid nested.pi_desc.
+
+Arguably, vmx_complete_nested_posted_interrupt() should first check for
+posted interrupts being enabled, but it's also completely reasonable that
+KVM wouldn't screw up a fundamental flag. Not to mention that the mere
+existence of nested.pi_pending is a long-standing bug as KVM shouldn't
+move the posted interrupt out of the IRR until it's actually processed,
+e.g. KVM effectively drops an interrupt when it performs a nested VM-Exit
+with a "pending" posted interrupt. Fixing the mess is a future problem.
+
+Prior to vmx_complete_nested_posted_interrupt() interpreting a null PI
+descriptor as an error, this was a benign bug as the null PI descriptor
+effectively served as a check on PI not being enabled. Even then, the
+new flow did not become problematic until KVM started checking the result
+of kvm_check_nested_events().
+
+Fixes: 705699a13994 ("KVM: nVMX: Enable nested posted interrupt processing")
+Fixes: 966eefb89657 ("KVM: nVMX: Disable vmcs02 posted interrupts if vmcs12 PID isn't mappable")

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Halil Pasic <pasic@linux.ibm.com>
+
+commit a3e03bc1368c1bc16e19b001fc96dc7430573cc8 upstream.
+
+While in practice vcpu->vcpu_idx == vcpu->vcp_id is often true, it may
+not always be, and we must not rely on this. Reason is that KVM decides
+the vcpu_idx, userspace decides the vcpu_id, thus the two might not
+match.
+
+Currently kvm->arch.idle_mask is indexed by vcpu_id, which implies
+that code like
+for_each_set_bit(vcpu_id, kvm->arch.idle_mask, online_vcpus) {
+ vcpu = kvm_get_vcpu(kvm, vcpu_id);
+ do_stuff(vcpu);
+}
+is not legit. Reason is that kvm_get_vcpu expects an vcpu_idx, not an
+vcpu_id. The trouble is, we do actually use kvm->arch.idle_mask like
+this. To fix this problem we have two options. Either use
+kvm_get_vcpu_by_id(vcpu_id), which would loop to find the right vcpu_id,
+or switch to indexing via vcpu_idx. The latter is preferable for obvious
+reasons.
+
+Let us make switch from indexing kvm->arch.idle_mask by vcpu_id to
+indexing it by vcpu_idx. To keep gisa_int.kicked_mask indexed by the
+same index as idle_mask lets make the same change for it as well.

+
+From: Zelin Deng <zelin.deng@linux.alibaba.com>
+
+commit d9130a2dfdd4b21736c91b818f87dbc0ccd1e757 upstream.
+
+When MSR_IA32_TSC_ADJUST is written by guest due to TSC ADJUST feature
+especially there's a big tsc warp (like a new vCPU is hot-added into VM
+which has been up for a long time), tsc_offset is added by a large value
+then go back to guest. This causes system time jump as tsc_timestamp is
+not adjusted in the meantime and pvclock monotonic character.
+To fix this, just notify kvm to update vCPU's guest time before back to
+guest.

+Subject: x86/resctrl: Fix a maybe-uninitialized build warning treated as error

+
+commit 527f721478bce3f49b513a733bacd19d6f34b08c upstream.
+
+The recent commit
+
+ 064855a69003 ("x86/resctrl: Fix default monitoring groups reporting")
+
+caused a RHEL build failure with an uninitialized variable warning
+treated as an error because it removed the default case snippet.
+
+The RHEL Makefile uses '-Werror=maybe-uninitialized' to force possibly
+uninitialized variable warnings to be treated as errors. This is also
+reported by smatch via the 0day robot.
+
+The error from the RHEL build is:
+
+ arch/x86/kernel/cpu/resctrl/monitor.c: In function ‘__mon_event_count’:
+ arch/x86/kernel/cpu/resctrl/monitor.c:261:12: error: ‘m’ may be used
+ uninitialized in this function [-Werror=maybe-uninitialized]
+ m->chunks += chunks;
+ ^~
+
+The upstream Makefile does not build using '-Werror=maybe-uninitialized'.
+So, the problem is not seen there. Fix the problem by putting back the
+default case snippet.
+
+ [ bp: note that there's nothing wrong with the code and other compilers
+ do not trigger this warning - this is being done just so the RHEL compiler
+ is happy. ]
