      s390: enable HAVE_IOREMAP_PROT · d460bb6c
      Niklas Schnelle authored 
      In commit b02002cc ("s390/pci: Implement ioremap_wc/prot() with
MIO") we implemented both ioremap_wc() and ioremap_prot() however until
now we had not set HAVE_IOREMAP_PROT in Kconfig, do so now.

This also requires implementing pte_pgprot() as this is used in the
generic_access_phys() code enabled by CONFIG_HAVE_IOREMAP_PROT. As with
ioremap_wc() we need to take the MMIO Write Back bit index into account.

Moreover since the pgprot value returned from pte_pgprot() is to be used
for mappings into kernel address space we must make sure that it uses
appropriate kernel page table protection bits. In particular a pgprot
value originally coming from userspace could have the _PAGE_PROTECT
bit set to enable fault based dirty bit accounting which would then make
the mapping inaccessible when used in kernel address space.

      s390/cpumf: remove WARN_ON_ONCE in counter start handler · 15e5b53f
      Thomas Richter authored 
      Remove some WARN_ON_ONCE() warnings when a counter is started. Each
counter is installed function calls
event_sched_in() --> cpumf_pmu_add(..., PERF_EF_START).

This is done after the event has been created using
perf_pmu_event_init() which verifies the counter is valid.
Member hwc->config must be valid at this point.

Function cpumf_pmu_start(..., PERF_EF_RELOAD) is called from
function cpumf_pmu_add() for counter events. All other invocations of
cpumf_pmu_start(..., PERF_EF_RELOAD) are from the performance subsystem
for sampling events.

      s390/cpumf: remove counter transaction call backs · d552a58d
      Thomas Richter authored 
      The command 'perf stat -e cycles ...' triggers the following function
sequence in the CPU Measurement Facility counter device driver:

perf_pmu_event_init()
  __hw_perf_event_init()
    validate_ctr_auth()
    validate_ctr_version()

During event creation, the counter number is checked in functions
validate_ctr_auth() and validate_ctr_version() to verify it is a valid
counter and supported by the hardware. If this is not the case, both
functions return an error and the event is not created. System call
perf_event_open() returns an error in this case.

Later on the event is installed in the kernel event subsystem and the
driver functions cpumf_pmu_add() and cpumf_pmu_commit_txn() are called
to install the counter event by the hardware.

Since both events have been verified at event creation, there is no need
to re-evaluate the authorization state. This can not change since on
 * LPARs the authorization change requires a restart of the LPAR (and
   thus a reboot of the kernel)
 * DPMs can not take resources away, just add them.

Also the sequence of CPU Measurement facility counter device driver
calls is
  cpumf_pmu_start_txn
  cpumf_pmu_add
  cpumf_pmu_start
  cpumf_pmu_commit_txn
for every single event. Which means the condition in cpumf_pmu_add()
is never met and validate_ctr_auth() is never called.

This leaves the counter device driver transaction functions with
just one task:
start_txn: Verify a transaction is not in flight and call
	perf_pmu_disable()
cancel_txn, commit_txn: Verify a transaction is in flight and call
	perf_pmu_enable()

The same functionality is provided by the default transaction handling
functions in kernel/events/core.c. Use those by removing the
counter device driver private call back functions.

 "A bunch of x86/urgent stuff accumulated for the last two weeks so

  It should be all totally risk-free, of course. :-)

   - Fix out-of-spec hardware (1st gen Hygon) which does not implement
     MSR_AMD64_SEV even though the spec clearly states so, and check
     CPUID bits first.

   - Send only one signal to a task when it is a SEGV_PKUERR si_code
     type.

   - Do away with all the wankery of reserving X amount of memory in the
     first megabyte to prevent BIOS corrupting it and simply and
     unconditionally reserve the whole first megabyte.

   - Make alternatives NOP optimization work at an arbitrary position
     within the patched sequence because the compiler can put
     single-byte NOPs for alignment anywhere in the sequence (32-bit
     retpoline), vs our previous assumption that the NOPs are only
     appended.

   - Force-disable ENQCMD[S] instructions support and remove
     update_pasid() because of insufficient protection against FPU state
     modification in an interrupt context, among other xstate horrors
     which are being addressed at the moment. This one limits the
     fallout until proper enablement.

   - Use cpu_feature_enabled() in the idxd driver so that it can be
     build-time disabled through the defines in disabled-features.h.

   - Fix LVT thermal setup for SMI delivery mode by making sure the APIC
     LVT value is read before APIC initialization so that softlockups
     during boot do not happen at least on one machine.

   - Mark all legacy interrupts as legacy vectors when the IO-APIC is

      commit 471fbbea ("ext4: handle casefolding with encryption") is
missing a few checks for the encryption key which are needed to
support deleting enrypted casefolded files when the key is not

This bug made it impossible to delete encrypted+casefolded directories
without the encryption key, due to errors like:

      ext4: fix memory leak in ext4_fill_super · afd09b61
      Alexey Makhalov authored 
      Buffer head references must be released before calling kill_bdev();
otherwise the buffer head (and its page referenced by b_data) will not
be freed by kill_bdev, and subsequently that bh will be leaked.

If blocksizes differ, sb_set_blocksize() will kill current buffers and
page cache by using kill_bdev(). And then super block will be reread
again but using correct blocksize this time. sb_set_blocksize() didn't
fully free superblock page and buffer head, and being busy, they were
not freed and instead leaked.

This can easily be reproduced by calling an infinite loop of:

  systemctl start <ext4_on_lvm>.mount, and
  systemctl stop <ext4_on_lvm>.mount

... since systemd creates a cgroup for each slice which it mounts, and
the bh leak get amplified by a dying memory cgroup that also never
gets freed, and memory consumption is much more easily noticed.

This patch's modification is according to Jan Kara's suggestion in:
https://patchwork.ozlabs.org/project/linux-ext4/patch/20210428085158.3728201-1-yebin10@huawei.com/
"I see. Now I understand your patch. Honestly, seeing how fragile is trying
to fix extent tree after split has failed in the middle, I would probably
go even further and make sure we fix the tree properly in case of ENOSPC
and EDQUOT (those are easily user triggerable).  Anything else indicates a
HW problem or fs corruption so I'd rather leave the extent tree as is and
don't try to fix it (which also means we will not create overlapping
extents)."
