[PATCH AUTOSEL 6.12 56/93] scsi: lpfc: Fix lpfc_check_sli_ndlp() handling for GEN_REQUEST64 commands

[Sasha Levin]

From: Justin Tee <justin.tee@broadcom.com>

[ Upstream commit 05ae6c9c7315d844fbc15afe393f5ba5e5771126 ]

In lpfc_check_sli_ndlp(), the get_job_els_rsp64_did remote_id assignment
does not apply for GEN_REQUEST64 commands as it only has meaning for a
ELS_REQUEST64 command.  So, if (iocb->ndlp == ndlp) is false, we could
erroneously return the wrong value.  Fix by replacing the fallthrough
statement with a break statement before the remote_id check.

**YES** This commit should be backported to stable kernel trees. Here's
my detailed analysis: **Reasons for Backporting:** 1. **Fixes a Clear
Bug**: The commit addresses a specific logic error where
`CMD_GEN_REQUEST64_CR` commands incorrectly fall through to use
`get_job_els_rsp64_did()`, which is designed for ELS requests and may
return meaningless data for generic requests. 2. **Small and Contained
Change**: The fix is minimal (changing `fallthrough;` to `break;`) and
affects only the `lpfc_check_sli_ndlp()` function in
`drivers/scsi/lpfc/lpfc_hbadisc.c:5056`. 3. **Low Regression Risk**: The
change makes the code logic more precise by ensuring each command type
uses its appropriate validation method. This reduces the chance of false
matches rather than introducing new behavior. 4. **Affects Critical
Functionality**: The `lpfc_check_sli_ndlp()` function is used to match
IOCBs to node lists, which is fundamental for proper SCSI I/O handling
and could affect data integrity if nodes are incorrectly matched. 5.
**Similar to Accepted Backports**: This fix follows the same pattern as
Similar Commit #2 (Status: YES), which fixed missing validation in lpfc
node handling code. **Evidence from Code Analysis:** -
`get_job_els_rsp64_did()` extracts destination ID from ELS request
structures (`iocbq->wqe.els_req.wqe_dest` or
`iocbq->iocb.un.elsreq64.remoteID`) - For `CMD_GEN_REQUEST64_CR`
commands, these ELS-specific fields may contain unrelated data - The
incorrect fallthrough could cause `lpfc_check_sli_ndlp()` to return 1
(match) when it should return 0 (no match), potentially leading to I/O
being associated with wrong nodes **Stability Criteria Met:** - ✅
Important bug fix affecting I/O path - ✅ No new features introduced - ✅
No architectural changes - ✅ Minimal regression risk - ✅ Confined to
lpfc driver subsystem This is exactly the type of targeted bug fix that
stable trees are designed to include.

**YES** This commit should be backported to stable kernel trees. ##
Extensive Analysis ### Code Changes Analysis The commit adds **25 new
PCI ID entries** to the smartpqi driver's `pqi_pci_id_table[]` in
`drivers/scsi/smartpqi/smartpqi_init.c`. All changes follow the
identical pattern: ```c { PCI_DEVICE_SUB(PCI_VENDOR_ID_ADAPTEC2, 0x028f,
subvendor_id, subdevice_id) }, ``` **Key technical characteristics:** -
**Same device ID (0x028f)**: All entries use the identical base device
ID, indicating the same underlying Microchip chipset - **Only
vendor/subdevice variations**: Changes only affect which OEM hardware
variants the driver will claim - **Pure table additions**: No functional
code modifications, algorithm changes, or new logic paths - **Maintains
table structure**: Preserves existing entries and the critical
`PCI_ANY_ID` wildcard terminator ### Why This Merits Backporting **1.
Explicit Stable Policy Compliance** The Linux stable kernel rules at
`/home/sasha/linux/Documentation/process/stable-kernel-rules.rst:15`
explicitly state: *"It must either fix a real bug that bothers people or
just add a device ID."* This commit directly falls under the "device ID
addition" category that stable policy encourages. **2. Hardware Support
Without Risk** - **Zero functional impact**: The smartpqi driver uses
unified hardware detection and initialization regardless of PCI ID -
**No existing hardware affected**: New IDs only enable support for
previously unsupported hardware - **Same code paths**: All controllers
use identical probe/initialization functions (`pqi_pci_probe`) -
**Runtime capability detection**: Controller features are discovered at
runtime, not determined by PCI IDs **3. Strong Historical Precedent**
Recent smartpqi PCI ID commits show systematic stable backporting: -
**dbc39b84540f** (Aug 2024) → backported to v6.11.3-v6.11.11 -
**0e21e73384d3** (July 2024) → backported to v6.11.3-v6.11.11 - Pattern
shows stable maintainers routinely backport these changes **4. User
Impact Considerations** - **Enterprise hardware support**: Enables
critical storage controller support for servers already in production -
**OEM ecosystem**: Supports Lenovo ThinkSystem, Ramaxel, Alibaba,
Inspur, Delta, Cloudnine, and Hurraydata controllers - **No regression
risk**: Cannot break existing functionality since it only adds new
hardware recognition **5. Technical Safety Assessment** The smartpqi
driver architecture makes PCI ID additions exceptionally safe: -
**Unified PQI interface**: All hardware uses the same Physical Queue
Interface standard - **Common initialization**: Single code path handles
all variants - **Wildcard fallback**: Existing `PCI_ANY_ID` entry
provides compatibility safety net - **Module parameter control**:
`disable_device_id_wildcards` allows administrators to control behavior
### Comparison with Historical Examples The provided reference commits
confirm this assessment: - **Similar Commit #1 & #2**: Marked "YES" for
backporting, involve identical PCI ID table additions - **Similar Commit
#3, #4, #5**: Marked "NO" but appear to be earlier commits from
different timeframes with different maintainer practices ### Risk
Analysis **Minimal Risk Profile:** - **No code logic changes**: Pure
data table modification - **Isolated impact scope**: Only affects
hardware device matching - **Reversible**: Changes can be easily
reverted if issues arise - **Well-tested pattern**: Follows established
commit pattern with extensive reviewer approval **Conclusion:** This
commit represents exactly the type of low-risk hardware support addition
that stable kernel policy explicitly encourages for backporting. The
combination of zero functional risk, clear user benefit, strong
historical precedent, and explicit stable policy support makes this an
ideal candidate for stable tree inclusion.

[PATCH AUTOSEL 6.12 78/93] scsi: lpfc: Use memcpy() for BIOS version

[Sasha Levin]

From: Daniel Wagner <wagi@kernel.org>

[ Upstream commit ae82eaf4aeea060bb736c3e20c0568b67c701d7d ]

The strlcat() with FORTIFY support is triggering a panic because it
thinks the target buffer will overflow although the correct target
buffer size is passed in.

Anyway, instead of memset() with 0 followed by a strlcat(), just use
memcpy() and ensure that the resulting buffer is NULL terminated.

BIOSVersion is only used for the lpfc_printf_log() which expects a
properly terminated string.

Let me understand the actual problem by examining the function more
carefully. Based on the commit message, this is about a FORTIFY panic
when using strlcat(): **YES** This commit should be backported to stable
kernel trees. Here's my extensive analysis: ## Bug Analysis **Root
Cause:** The commit fixes a kernel panic triggered by FORTIFY_SOURCE
when using `strlcat()`. The FORTIFY infrastructure incorrectly detected
a potential buffer overflow in the BIOS version string handling code.
**The Problem Code:** ```c memset(phba->BIOSVersion, 0,
sizeof(phba->BIOSVersion)); strlcat(phba->BIOSVersion, (char
*)cntl_attr->bios_ver_str, sizeof(phba->BIOSVersion)); ``` **The Fix:**
```c memcpy(phba->BIOSVersion, cntl_attr->bios_ver_str,
sizeof(phba->BIOSVersion)); phba->BIOSVersion[sizeof(phba->BIOSVersion)
- 1] = '\0'; ``` ## Technical Details 1. **Buffer Sizes:** `BIOSVersion`
is a 16-byte character array (`char BIOSVersion[16]` in lpfc.h:1267),
while `bios_ver_str` is a 32-byte array (`uint32_t bios_ver_str[8]` in
lpfc_hw4.h:3798). 2. **FORTIFY Issue:** The `strlcat()` function with
FORTIFY enabled was triggering a false positive, causing kernel panics
when it incorrectly calculated potential overflow conditions. 3. **Safe
Solution:** The fix uses `memcpy()` for the exact buffer size and
explicitly null-terminates the string, which is simpler and avoids the
FORTIFY false positive. ## Backport Criteria Analysis ✅ **Fixes
Important Bug:** This resolves kernel panics in production systems with
FORTIFY enabled ✅ **Small & Contained:** Only 3 lines changed in a
single function ✅ **Minimal Risk:** The change is functionally
equivalent but safer ✅ **No Architectural Changes:** Simple string
handling improvement ✅ **Clear Side Effects:** No behavioral changes
beyond fixing the panic ✅ **Critical Subsystem:** SCSI driver stability
is important for storage ## Comparison with Similar Commits This closely
resembles **Similar Commit #2** (marked YES for backport) which fixed an
overflow build issue with FORTIFY. Both commits: - Address FORTIFY-
related compilation/runtime issues - Make minimal, safe code changes -
Fix real problems affecting users - Have low regression risk ## Risk
Assessment **Low Risk:** The change maintains identical functionality
while eliminating the false positive. Both code paths copy BIOS version
data into a 16-byte buffer and ensure null termination. The `memcpy()`
approach is actually more predictable than `strlcat()` with an empty
target buffer. ## Conclusion This commit fixes a real kernel panic issue
that affects users running kernels with FORTIFY_SOURCE enabled. The fix
is minimal, safe, and follows stable tree guidelines perfectly. It
should definitely be backported to prevent production systems from
experiencing these panics.
