e87e08c94c drm/amdgpu: fix use-after-free bug 
commit 22207fd5c80177b860279653d017474b2812af5e upstream.

The bug can be triggered by sending a single amdgpu_gem_userptr_ioctl
to the AMDGPU DRM driver on any ASICs with an invalid address and size.
The bug was reported by Joonkyo Jung <joonkyoj@yonsei.ac.kr>.
For example the following code:

static void Syzkaller1(int fd)
{
	struct drm_amdgpu_gem_userptr arg;
	int ret;

	arg.addr = 0xffffffffffff0000;
	arg.size = 0x80000000; /*2 Gb*/
	arg.flags = 0x7;
	ret = drmIoctl(fd, 0xc1186451/*amdgpu_gem_userptr_ioctl*/, &arg);
}

Due to the address and size are not valid there is a failure in
amdgpu_hmm_register->mmu_interval_notifier_insert->__mmu_interval_notifier_insert->
check_shl_overflow, but we even the amdgpu_hmm_register failure we still call
amdgpu_hmm_unregister into  amdgpu_gem_object_free which causes access to a bad address.
The following stack is below when the issue is reproduced when Kazan is enabled:

4338e40da8 x86/sev: Skip ROM range scans and validation for SEV-SNP guests 
commit 0f4a1e80989aca185d955fcd791d7750082044a2 upstream.

SEV-SNP requires encrypted memory to be validated before access.
Because the ROM memory range is not part of the e820 table, it is not
pre-validated by the BIOS. Therefore, if a SEV-SNP guest kernel wishes
to access this range, the guest must first validate the range.

The current SEV-SNP code does indeed scan the ROM range during early
boot and thus attempts to validate the ROM range in probe_roms().
However, this behavior is neither sufficient nor necessary for the
following reasons:

* With regards to sufficiency, if EFI_CONFIG_TABLES are not enabled and
  CONFIG_DMI_SCAN_MACHINE_NON_EFI_FALLBACK is set, the kernel will
  attempt to access the memory at SMBIOS_ENTRY_POINT_SCAN_START (which
  falls in the ROM range) prior to validation.

  For example, Project Oak Stage 0 provides a minimal guest firmware
  that currently meets these configuration conditions, meaning guests
  booting atop Oak Stage 0 firmware encounter a problematic call chain
  during dmi_setup() -> dmi_scan_machine() that results in a crash
  during boot if SEV-SNP is enabled.

* With regards to necessity, SEV-SNP guests generally read garbage
  (which changes across boots) from the ROM range, meaning these scans
  are unnecessary. The guest reads garbage because the legacy ROM range
  is unencrypted data but is accessed via an encrypted PMD during early
  boot (where the PMD is marked as encrypted due to potentially mapping
  actually-encrypted data in other PMD-contained ranges).

In one exceptional case, EISA probing treats the ROM range as
unencrypted data, which is inconsistent with other probing.

Continuing to allow SEV-SNP guests to use garbage and to inconsistently
classify ROM range encryption status can trigger undesirable behavior.
For instance, if garbage bytes appear to be a valid signature, memory
may be unnecessarily reserved for the ROM range. Future code or other
use cases may result in more problematic (arbitrary) behavior that
should be avoided.

While one solution would be to overhaul the early PMD mapping to always
treat the ROM region of the PMD as unencrypted, SEV-SNP guests do not
currently rely on data from the ROM region during early boot (and even
if they did, they would be mostly relying on garbage data anyways).

As a simpler solution, skip the ROM range scans (and the otherwise-
necessary range validation) during SEV-SNP guest early boot. The
potential SEV-SNP guest crash due to lack of ROM range validation is
thus avoided by simply not accessing the ROM range.

In most cases, skip the scans by overriding problematic x86_init
functions during sme_early_init() to SNP-safe variants, which can be
likened to x86_init overrides done for other platforms (ex: Xen); such
overrides also avoid the spread of cc_platform_has() checks throughout
the tree.

In the exceptional EISA case, still use cc_platform_has() for the
simplest change, given (1) checks for guest type (ex: Xen domain status)
are already performed here, and (2) these checks occur in a subsys
initcall instead of an x86_init function.

2048ff503f scsi: libsas: Fix disk not being scanned in after being removed 
commit 8e68a458bcf5b5cb9c3624598bae28f08251601f upstream.

As of commit d8649fc1c5 ("scsi: libsas: Do discovery on empty PHY to
update PHY info"), do discovery will send a new SMP_DISCOVER and update
phy->phy_change_count. We found that if the disk is reconnected and phy
change_count changes at this time, the disk scanning process will not be
triggered.

Therefore, call sas_set_ex_phy() to update the PHY info with the results of
the last query. And because the previous phy info will be used when calling
sas_unregister_devs_sas_addr(), sas_unregister_devs_sas_addr() should be
called before sas_set_ex_phy().

This was reverts commit 8009479ee919b9a91674f48050ccbff64eafedaa.

It was originally in x86/urgent, but was deemed wrong so got zapped.
But in the meantime, x86/urgent had been merged into x86/apic to
resolve a conflict.  I didn't notice the merge so didn't zap it
from x86/apic and it managed to make it up with the x86/apic
material.

The reverted commit is known to cause some KASAN problems.

367b4ce0d7 x86/bugs: Use fixed addressing for VERW operand 
commit 8009479ee919b9a91674f48050ccbff64eafedaa upstream.

The macro used for MDS mitigation executes VERW with relative
addressing for the operand. This was necessary in earlier versions of
the series. Now it is unnecessary and creates a problem for backports
on older kernels that don't support relocations in alternatives.
Relocation support was added by commit 270a69c448 ("x86/alternative:
Support relocations in alternatives").  Also asm for fixed addressing
is much cleaner than relative RIP addressing.

Simplify the asm by using fixed addressing for VERW operand.

Instead, wait for the OS or system to notify driver to wind down I/O

f14cee7a88 scsi: qla2xxx: Fix double free of the ha->vp_map pointer 
commit e288285d47784fdcf7c81be56df7d65c6f10c58b upstream.

Coverity scan reported potential risk of double free of the pointer
ha->vp_map.  ha->vp_map was freed in qla2x00_mem_alloc(), and again freed
in function qla2x00_mem_free(ha).

Assign NULL to vp_map and kfree take care of NULL.

The system was under memory stress where driver was not able to allocate an
SRB to carry out error recovery of cable pull.  The failure to flush causes
upper layer to start modifying scsi_cmnd.  When the system frees up some
memory, the subsequent cable pull trigger another command flush. At this
point the driver access a null pointer when attempting to DMA unmap the
SGL.

Add a check to make sure commands are flush back on session tear down to
prevent the null pointer access.

Changing of [FCP|NVME] prefer flag in flash has no effect on driver. For
device that supports both FCP + NVMe over the same connection, driver
continues to connect to this device using the previous successful login
mode.

On completion of flash update, adapter will be reset. Driver will
reset the prefer flag based on setting from flash.

Disk failed to rediscover after chip reset error injection. The chip reset
happens at the time when a PLOGI is being sent. This causes a flag to be
left on which blocks the retry. Clear the blocking flag.

commit 4895009c4bb72f71f2e682f1e7d2c2d96e482087 upstream.

Currently IOCBs are allowed to push through while chip reset could be in
progress. During chip reset the outstanding_cmds array is cleared
twice. Once when any command on this array is returned as failed and
secondly when the array is initialize to zero. If a command is inserted on
to the array between these intervals, then the command will be lost.  Check
for chip reset before sending IOCB.

1f510af8db usb: typec: ucsi_acpi: Refactor and fix DELL quirk 
commit 6aaceb7d9cd00f3e065dc4b054ecfe52c5253b03 upstream.

Some DELL systems don't like UCSI_ACK_CC_CI commands with the
UCSI_ACK_CONNECTOR_CHANGE but not the UCSI_ACK_COMMAND_COMPLETE
bit set. The current quirk still leaves room for races because
it requires two consecutive ACK commands to be sent.

Refactor and significantly simplify the quirk to fix this:
Send a dummy command and bundle the connector change ack with the
command completion ack in a single UCSI_ACK_CC_CI command.
This removes the need to probe for the quirk.

While there define flag bits for struct ucsi_acpi->flags in ucsi_acpi.c
and don't re-use definitions from ucsi.h for struct ucsi->flags.

Fixes: f3be347ea42d ("usb: ucsi_acpi: Quirk to ack a connector change ack cmd")
