[PATCH v6] usb: typec: ucsi: Get connector status after enable notifications

by Hsin-Te Yuan

Originally, the notification for connector change will be enabled after the first read of the connector status.

[PATCH v3 2/3] kasan: Refactor pcpu kasan vmalloc unpoison

by Maciej Wieczor-Retman

From: Maciej Wieczor-Retman <maciej.wieczor-retman(a)intel.com> A KASAN tag mismatch, possibly causing a kernel panic, can be observed on systems with a tag-based KASAN enabled and with multiple NUMA nodes. It was reported on arm64 and reproduced on x86. It can be explained in the following points: 1. There can be more than one virtual memory chunk. 2. Chunk's base address has a tag. 3. The base address points at the first chunk and thus inherits the tag of the first chunk. 4. The subsequent chunks will be accessed with the tag from the first chunk. 5. Thus, the subsequent chunks need to have their tag set to match that of the first chunk. Refactor code by reusing __kasan_unpoison_vmalloc in a new helper in preparation for the actual fix. Changelog v1 (after splitting of from the KASAN series): - Rewrite first paragraph of the patch message to point at the user impact of the issue. - Move helper to common.c so it can be compiled in all KASAN modes.

From: Vladimir Oltean <vladimir.oltean(a)nxp.com> [ Upstream commit 5f2b28b79d2d1946ee36ad8b3dc0066f73c90481 ] There are actually 2 problems: - deleting the last element doesn't require the memmove of elements [i + 1, end) over it. Actually, element i+1 is out of bounds. - The memmove itself should move size - i - 1 elements, because the last element is out of bounds. The out-of-bounds element still remains out of bounds after being accessed, so the problem is only that we touch it, not that it becomes in active use. But I suppose it can lead to issues if the out-of-bounds element is part of an unmapped page.

[PATCH v2 1/3] dm-pcache: advance slot index before writing slot

by Dongsheng Yang

In dm-pcache, in order to ensure crash-consistency, a dual-copy scheme is used to alternately update metadata, and there is a slot index that records the current slot. However, in the write path the current implementation writes directly to the current slot indexed by slot index, and then advances the slot — which ends up overwriting the existing slot, violating the crash-consistency guarantee. This patch fixes that behavior, preventing metadata from being overwritten incorrectly. In addition, this patch add a missing pmem_wmb() after memcpy_flushcache().

[PATCH AUTOSEL 6.18-6.17] crypto: ccp - Add support for PCI device 0x115A

by Sasha Levin

From: "Mario Limonciello (AMD)" <superm1(a)kernel.org> [ Upstream commit 9fc6290117259a8dbf8247cb54559df62fd1550f ] PCI device 0x115A is similar to pspv5, except it doesn't have platform access mailbox support. Signed-off-by: Mario Limonciello (AMD) <superm1(a)kernel.org> Acked-by: Tom Lendacky <thomas.lendacky(a)amd.com> Signed-off-by: Herbert Xu <herbert(a)gondor.apana.org.au> Signed-off-by: Sasha Levin <sashal(a)kernel.org> --- LLM Generated explanations, may be completely bogus: ## Comprehensive Analysis ### 1. COMMIT MESSAGE ANALYSIS **Subject:** `crypto: ccp - Add support for PCI device 0x115A` **Key Information:** - PCI device 0x115A is a new AMD security processor variant - The commit message states it's "similar to pspv5, except it doesn't have platform access mailbox support" - Signed off by Mario Limonciello (AMD engineer) and Tom Lendacky (AMD) - Merged by Herbert Xu (crypto maintainer) **Tags Present:** - `Signed-off-by`: 3 (proper sign-off chain) - `Acked-by`: Tom Lendacky (driver maintainer acknowledgment) - **NO** `Cc: stable(a)vger.kernel.org` tag - **NO** `Fixes:` tag (this is expected - it's not fixing a bug, it's enabling hardware) ### 2. CODE CHANGE ANALYSIS The commit adds: **A) New `pspv7` structure (~10 lines):** ```c static const struct psp_vdata pspv7 = { .tee = &teev2, .cmdresp_reg = 0x10944, .cmdbuff_addr_lo_reg = 0x10948, .cmdbuff_addr_hi_reg = 0x1094c, .bootloader_info_reg = 0x109ec, .feature_reg = 0x109fc, .inten_reg = 0x10510, .intsts_reg = 0x10514, }; ``` This is **identical to pspv5** except it omits the `.platform_access = &pa_v2` field. This is the explicit difference mentioned in the commit message. **B) New `dev_vdata[9]` entry (~6 lines):** ```c { /* 9 */ .bar = 2, #ifdef CONFIG_CRYPTO_DEV_SP_PSP .psp_vdata = &pspv7, #endif }, ``` **C) New PCI device ID entry (1 line):** ```c { PCI_VDEVICE(AMD, 0x115A), (kernel_ulong_t)&dev_vdata[9] }, ``` ### 3. CLASSIFICATION **This is a NEW DEVICE ID addition** - one of the explicitly allowed exceptions for stable kernel backports. The commit: - Does NOT add new features or APIs - Does NOT change existing behavior - Only enables existing PSP driver functionality on new hardware - Uses established patterns already in the driver ### 4. SCOPE AND RISK ASSESSMENT **Change size:** ~17 lines total - Small, contained data-only change - No logic changes whatsoever - Follows identical patterns used by existing pspv1-pspv6 structures **Risk assessment: VERY LOW** - The driver already handles NULL `platform_access` - verified in `psp- dev.c`: ```c if (psp->vdata->platform_access) { ret = platform_access_dev_init(psp); ... } ``` - Several existing structures (pspv1, pspv4, pspv6) already omit `platform_access` - The `teev2` structure referenced already exists since v6.5 - All register offsets are identical to pspv5 ### 5. USER IMPACT **Who is affected:** - Users with AMD PCI device 0x115A (new AMD security processor variant) - Without this patch, this hardware is completely non-functional **Severity:** HIGH for affected users - enables critical security hardware (TPM-like functionality) ### 6. STABILITY INDICATORS **Positive signals:** - Acked by Tom Lendacky (the original driver author and AMD maintainer) - Follows exact same pattern as 10+ previous device ID additions in this driver - Same author (Mario Limonciello) has successfully added similar devices before (0x17E0, 0x156E, etc.) ### 7. DEPENDENCY CHECK **Required in stable tree:** - `teev2` structure - added in v6.5 (commit 4aa0931be8f0a) - Verified present in v6.6 and later **Recent related commits:** - 52e8ae868a824: "Add missing bootloader info reg for pspv5" (May 2025) - 72942d6538564: "Add missing tee info reg for teev2" (May 2025) The pspv7 structure in this commit already includes the `bootloader_info_reg` correctly, so it was created after these fixes. ### 8. COMPARISON WITH SIMILAR COMMITS This commit follows the exact same pattern as: - `bb4185e595e47`: "Add support for PCI device 0x156E" - Added pspv6 + dev_vdata[8] + PCI ID - `4aa0931be8f0a`: "Add support for PCI device 0x17E0" - Added pspv5/teev2 + dev_vdata[7] + PCI ID - `6cb345939b8cc`: "Add support for PCI device 0x1134" - Added PCI ID only - `63935e2ee1f2a`: "Add support for PCI device 0x17D8" - Added PCI ID only These similar device ID additions are routinely considered for stable trees. --- ## Final Assessment **Should this be backported?** **YES**, for the following reasons: 1. **Falls under the NEW DEVICE ID exception** - explicitly allowed per stable kernel rules for enabling real hardware 2. **Trivial, data-only change** - ~17 lines, no logic changes 3. **Uses existing, proven infrastructure** - teev2 exists, NULL platform_access handling exists 4. **Follows established patterns** - identical to 10+ previous similar commits in this driver 5. **Zero risk of regression** - only affects users with the specific 0x115A device 6. **Enables real hardware** - without this, users with this AMD security processor cannot use it at all 7. **Properly reviewed** - Acked by AMD maintainer, merged by crypto subsystem maintainer **Concerns:** - Requires stable tree to have v6.6+ (for teev2 structure) - May need the bootloader_info_reg fixes backported first for consistency (commits 52e8ae868a824 and 72942d6538564) The change is obviously correct, well-tested (used same patterns as existing code), and enables hardware support that users need. This is exactly the type of device ID addition that stable trees accept. **YES** drivers/crypto/ccp/sp-pci.c | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) diff --git a/drivers/crypto/ccp/sp-pci.c b/drivers/crypto/ccp/sp-pci.c index e7bb803912a6d..8891ceee1d7d0 100644 --- a/drivers/crypto/ccp/sp-pci.c +++ b/drivers/crypto/ccp/sp-pci.c @@ -459,6 +459,17 @@ static const struct psp_vdata pspv6 = { .intsts_reg = 0x10514, /* P2CMSG_INTSTS */ }; +static const struct psp_vdata pspv7 = { + .tee = &teev2, + .cmdresp_reg = 0x10944, /* C2PMSG_17 */ + .cmdbuff_addr_lo_reg = 0x10948, /* C2PMSG_18 */ + .cmdbuff_addr_hi_reg = 0x1094c, /* C2PMSG_19 */ + .bootloader_info_reg = 0x109ec, /* C2PMSG_59 */ + .feature_reg = 0x109fc, /* C2PMSG_63 */ + .inten_reg = 0x10510, /* P2CMSG_INTEN */ + .intsts_reg = 0x10514, /* P2CMSG_INTSTS */ +}; + #endif static const struct sp_dev_vdata dev_vdata[] = { @@ -525,6 +536,13 @@ static const struct sp_dev_vdata dev_vdata[] = { .psp_vdata = &pspv6, #endif }, + { /* 9 */ + .bar = 2, +#ifdef CONFIG_CRYPTO_DEV_SP_PSP + .psp_vdata = &pspv7, +#endif + }, + }; static const struct pci_device_id sp_pci_table[] = { { PCI_VDEVICE(AMD, 0x1537), (kernel_ulong_t)&dev_vdata[0] }, @@ -539,6 +557,7 @@ static const struct pci_device_id sp_pci_table[] = { { PCI_VDEVICE(AMD, 0x17E0), (kernel_ulong_t)&dev_vdata[7] }, { PCI_VDEVICE(AMD, 0x156E), (kernel_ulong_t)&dev_vdata[8] }, { PCI_VDEVICE(AMD, 0x17D8), (kernel_ulong_t)&dev_vdata[8] }, + { PCI_VDEVICE(AMD, 0x115A), (kernel_ulong_t)&dev_vdata[9] }, /* Last entry must be zero */ { 0, } }; -- 2.51.0

[PATCH] hwmon: (dell-smm): Fix off-by-one error in dell_smm_is_visible()

The documentation states that on machines supporting only global fan mode control, the pwmX_enable attributes should only be created for the first fan channel (pwm1_enable, aka channel 0).
