Please backport 2d43cc701b96 to v6.9 and v6.6

by Michael Ellerman

Hi stable team, Can you please backport: 2d43cc701b96 ("powerpc/uaccess: Fix build errors seen with GCC 13/14") To v6.9 and v6.6. It was marked for backporting, but hasn't been picked up AFAICS. I'm not sure if it clashed with the asm_goto_output changes or something. But it backports cleanly to the current stable branches. It needs a custom backport for earlier kernels, I'll send those. cheers

[PATCH v6.1] powerpc/uaccess: Fix build errors seen with GCC 13/14

by Michael Ellerman

commit 2d43cc701b96f910f50915ac4c2a0cae5deb734c upstream. Building ppc64le_defconfig with GCC 14 fails with assembler errors: CC fs/readdir.o /tmp/ccdQn0mD.s: Assembler messages: /tmp/ccdQn0mD.s:212: Error: operand out of domain (18 is not a multiple of 4) /tmp/ccdQn0mD.s:226: Error: operand out of domain (18 is not a multiple of 4) ... [6 lines] /tmp/ccdQn0mD.s:1699: Error: operand out of domain (18 is not a multiple of 4) A snippet of the asm shows: # ../fs/readdir.c:210: unsafe_copy_dirent_name(dirent->d_name, name, namlen, efault_end); ld 9,0(29) # MEM[(u64 *)name_38(D) + _88 * 1], MEM[(u64 *)name_38(D) + _88 * 1] # 210 "../fs/readdir.c" 1 1: std 9,18(8) # put_user # *__pus_addr_52, MEM[(u64 *)name_38(D) + _88 * 1] The 'std' instruction requires a 4-byte aligned displacement because it is a DS-form instruction, and as the assembler says, 18 is not a multiple of 4. A similar error is seen with GCC 13 and CONFIG_UBSAN_SIGNED_WRAP=y. The fix is to change the constraint on the memory operand to put_user(), from "m" which is a general memory reference to "YZ". The "Z" constraint is documented in the GCC manual PowerPC machine constraints, and specifies a "memory operand accessed with indexed or indirect addressing". "Y" is not documented in the manual but specifies a "memory operand for a DS-form instruction". Using both allows the compiler to generate a DS-form "std" or X-form "stdx" as appropriate. Unfortunately clang doesn't support the "Y" constraint so that has to be behind an ifdef. Although the build error is only seen with GCC 13/14, that appears to just be luck. The constraint has been incorrect since it was first added.

[PATCH v6] af_packet: Handle outgoing VLAN packets without hardware offloading

by Chengen Du

The issue initially stems from libpcap. The ethertype will be overwritten as the VLAN TPID if the network interface lacks hardware VLAN offloading. In the outbound packet path, if hardware VLAN offloading is unavailable, the VLAN tag is inserted into the payload but then cleared from the sk_buff struct. Consequently, this can lead to a false negative when checking for the presence of a VLAN tag, causing the packet sniffing outcome to lack VLAN tag information (i.e., TCI-TPID). As a result, the packet capturing tool may be unable to parse packets as expected. The TCI-TPID is missing because the prb_fill_vlan_info() function does not modify the tp_vlan_tci/tp_vlan_tpid values, as the information is in the payload and not in the sk_buff struct. The skb_vlan_tag_present() function only checks vlan_all in the sk_buff struct. In cooked mode, the L2 header is stripped, preventing the packet capturing tool from determining the correct TCI-TPID value. Additionally, the protocol in SLL is incorrect, which means the packet capturing tool cannot parse the L3 header correctly.

Intel e1000e driver bug on stable (6.9.x)

by Ismael Luceno

Hi, I noticed that the NIC started to fail on a couple of notebooks [0] [1] after upgrading to 6.9.1. I tracked down the problem to commit 861e8086029e ("e1000e: move force SMBUS from enable ulp function to avoid PHY loss issue", 2024-03-03), included in all 6.9.x releases. The fix is in commit bfd546a552e1 ("e1000e: move force SMBUS near the end of enable_ulp function", 2024-05-28) from mainline. The NIC fails right after boot on both systems I tried; I mention because the description is a bit unclear about that on the fix, maybe other systems are affected differently. Best regards. [0] HP ZBook 17 Gen 1 (D5D93AV) [8086:153a (rev 04)] [1] Lenovo Thinkpad P15 Gen 1 [8086:0d4c]

[PATCH 6.6] Revert "fork: defer linking file vma until vma is fully initialized"

by Sam James

This reverts commit cec11fa2eb512ebe3a459c185f4aca1d44059bbf. The backport is incomplete and causes xfstests failures. The consequences of the incomplete backport seem worse than the original issue, so pick the lesser evil and revert until a full backport is ready.

But then unpoison_memory() will decrease the folio refcnt unexpectedly as it appears like a successfully hwpoisoned folio leading to VM_BUG_ON_PAGE(page_ref_count(page) == 0) when releasing huge_zero_folio. Skip unpoisoning huge_zero_folio in unpoison_memory() to fix this issue. We're not prepared to unpoison huge_zero_folio yet.

[PATCH] fbdev: vesafb: Detect VGA compatibility from screen info's VESA attributes

by Thomas Zimmermann

Test the vesa_attributes field in struct screen_info for compatibility with VGA hardware. Vesafb currently tests bit 1 in screen_info's capabilities field, It sets the framebuffer address size and is unrelated to VGA. Section 4.4 of the Vesa VBE 2.0 specifications defines that bit 5 in the mode's attributes field signals VGA compatibility. The mode is compatible with VGA hardware if the bit is clear. In that case, the driver can access VGA state of the VBE's underlying hardware. The vesafb driver uses this feature to program the color LUT in palette modes. Without, colors might be incorrect. The problem got introduced in commit 89ec4c238e7a ("[PATCH] vesafb: Fix incorrect logo colors in x86_64"). It incorrectly stores the mode attributes in the screen_info's capabilities field and updates vesafb accordingly. Later, commit 5e8ddcbe8692 ("Video mode probing support for the new x86 setup code") fixed the screen_info, but did not update vesafb. Color output still tends to work, because bit 1 in capabilities is usually 0. Besides fixing the bug in vesafb, this commit introduces a helper that reads the correct bit from screen_info.
