kbuild: pacman-pkg: make "rc" releases adhere to pacman versioning scheme
The package versioning scheme does not enable smooth upgrades from "rc"
releases to the corresponding stable releases (e.g. 7.0.0-rc7 -> 7.0.0)
because pacman considers that a downgrade due to the underscore in
pkgver (e.g. 7.0.0_rc7), see e.g. vercmp(8) for an explanation of the
package version comparison used by pacman. Package versions which are
derived from said releases (e.g. built from git revisions) are
similarly affected. Fix this by modifying pkgver in order to remove the
hyphen from kernel versions containing "-rcN", where N is a
non-negative integer.

modpost: prevent stack buffer overflow in do_input_entry() and do_dmi_entry()
Several functions in scripts/mod/file2alias.c build the module alias
string by repeatedly appending into a fixed-size on-stack buffer:
char alias[256] = {};
...
sprintf(alias + strlen(alias), "%X,*", i);
This pattern is unbounded and silently corrupts the stack when the
formatted output exceeds the destination size. Two functions in this
file are realistically reachable with input that overflows their
buffer:
1. do_input_entry() appends across nine bitmap classes

ata: libata-scsi: do not needlessly defer commands when using PMP with FBS
The ACS specification does not allow a non-NCQ command to be issued while
an NCQ command is outstanding.
Commit 0ea84089dbf6 ("ata: libata-scsi: avoid Non-NCQ command starvation")
introduced a feature where a deferred non-NCQ command gets issued from a
workqueue. The design stores a single non-NCQ command per port.
However, when using Port Multipliers (PMPs), specifically PMPs that
support FIS-Based Switching (FBS), non-NCQ and NCQ commands can be mixed
on the same port, just not for the same link, see e.g. ata_std_qc_defer()
which is, and always has operated on a per-link basis.
Therefore, move the deferred_qc from struct ata_port to struct ata_link.
This way, when using a PMP with FBS, we will not needlessly defer commands
to all other links, just because one link issued a non-NCQ command while
having an NCQ command outstanding. Only commands for that specific link
will be deferred. This is in line with how PMPs with FBS worked before
[6 lines not shown]
ata: libata-scsi: do not use the deferred QC feature on PMPs with CBS
When using Port Multipliers (PMPs) with Command-Based Switching (CBS), you
can only issue commands to one link at a time. For PMPs with CBS, there is
already code to handle commands being sent to different links in
sata_pmp_qc_defer_cmd_switch() using ap->excl_link. sata_sil24 also makes
use of ap->excl_link.
A user on the list reported that commit 0ea84089dbf6 ("ata: libata-scsi:
avoid Non-NCQ command starvation") broke PMPs with CBS. The commit
introduced code that stores a deferred qc in ap->deferred_qc, to later be
issued via a workqueue. It turns out that this change is incompatible with
the existing ap->excl_link handling used by PMPs with CBS.
Thus, modify sata_pmp_qc_defer_cmd_switch() and sil24_qc_defer() to return
ATA_DEFER_LINK_EXCL, and make sure that the deferred QC handling via
workqueue is not used for this return value.
This way, PMPs with CBS will work once again. Note that the starvation

ata: libata-scsi: do not use the deferred QC feature for ATA_DEFER_PORT
The deferred QC feature was meant to handle mixed NCQ and non-NCQ commands,
i.e. for return value ATA_DEFER_LINK.
ATA_DEFER_PORT is returned by PATA drivers, but also certain SATA drivers
like sata_mv and sata_sil24 that uses ap->excl_link to workaround hardware
bugs in these HBAs. Regardless of the reason, using the deferred QC feature
for ATA_DEFER_PORT is always wrong, and will break the ap->excl_link usage
of the SATA drivers that rely on that feature.
Modify ata_scsi_qc_issue() to only use the deferred QC feature when mixing
NCQ and non-NCQ commands, i.e. ATA_DEFER_LINK.

- Fix remote_test error path
If one of the simple ring buffers fails to load, the code is supposed
to rollback its initialized buffers. Instead of rolling back the
buffers for the failed load, it uses the global variable and rolls
back all the successfully loaded buffers.

tracing: Fix desc in error path for the trace remote test module

virt: sev-guest: Do not use host-controlled page order in cleanup path
When issuing an extended guest request (SVM_VMGEXIT_EXT_GUEST_REQUEST),
get_ext_report() allocates a buffer to retrieve a certificate blob from the
host, keeping track of its size in report_req->certs_len.
However, the host may return SNP_GUEST_VMM_ERR_INVALID_LEN, indicating
an invalid buffer size, as well as the expected length of such buffer.
get_ext_report() subsequently updates report_req->certs_len with the
host-controlled value, and cleans up the buffer by computing a page order
from such value. This is incorrect, as the host-provided length may not
match the page order of the original allocation, potentially resulting
in corruption in the page allocator.
Fix this by using alloc_pages_exact() instead, and reusing @npages to
compute the size passed to free_pages_exact(). For consistency, also
use @npages to compute the size when allocating the pages, even though
this last change has no functional effect.

successful load completion. Fix the error path by using the local
