[PATCH 5.15.y 0/3] v5.15: fix build with GCC 15

by Matthieu Baerts (NGI0)

This kernel version doesn't build with GCC 15: In file included from include/uapi/linux/posix_types.h:5, from include/uapi/linux/types.h:14, from include/linux/types.h:6, from arch/x86/realmode/rm/wakeup.h:11, from arch/x86/realmode/rm/wakemain.c:2: include/linux/stddef.h:11:9: error: cannot use keyword 'false' as enumeration constant 11 | false = 0, | ^~~~~ include/linux/stddef.h:11:9: note: 'false' is a keyword with '-std=c23' onwards include/linux/types.h:30:33: error: 'bool' cannot be defined via 'typedef' 30 | typedef _Bool bool; | ^~~~ include/linux/types.h:30:33: note: 'bool' is a keyword with '-std=c23' onwards include/linux/types.h:30:1: warning: useless type name in empty declaration 30 | typedef _Bool bool; | ^~~~~~~ I initially fixed this by adding -std=gnu11 in arch/x86/Makefile, then I realised this fix was already done in an upstream commit, created before the GCC 15 release and not mentioning the error I had. This is the first patch. When I was investigating my error, I noticed other commits were already backported to v5.15. They were all adding -std=gnu11 in different Makefiles. In their commit message, they were mentioning 'gnu11' was picked to use the same as the one from the main Makefile. But this is not the case in this kernel version. Patch 2 fixes that. Finally, I noticed the documentation was not correct in this kernel version: this is because a commit was backported to v5.15 while it was not supposed to. Patch 3 fixes that.

Missing backport of 3c591faadd8a ("Reapply "Revert drm/amd/display: Enable Freesync Video Mode by default"") in 6.1.y stable series?

by Salvatore Bonaccorso

Hi We got in Debian a request to backport 3c591faadd8a ("Reapply "Revert drm/amd/display: Enable Freesync Video Mode by default"") for the kernel in Debian bookworm, based on 6.1.y stable series. https://bugs.debian.org/1119232 While looking at he request, I noticed that the series of commits had a bit of a convuluted history. AFAICT the story began with: de05abe6b9d0 ("drm/amd/display: Enable Freesync Video Mode by default"), this landed in 5.18-rc1 (and backported to v6.1.5, v6.0.19). This was then reverted with 4243c84aa082 ("Revert "drm/amd/display: Enable Freesync Video Mode by default""), which landed in v6.3-rc1 (and in turn was backported to v6.1.53). So far we are in sync. The above was then reverted again, via 11b92df8a2f7 ("Revert "Revert drm/amd/display: Enable Freesync Video Mode by default"") applied in v6.5-rc1 and as well backported to v6.1.53 (so still in sync). Now comes were we are diverging: 3c591faadd8a ("Reapply "Revert drm/amd/display: Enable Freesync Video Mode by default"") got applied later on, landing in v6.9-rc1 but *not* in 6.1.y anymore. I suspect this one was not applied to 6.1.y because in meanwhile there was a conflict to cherry-pick it cleanly due to context changes due to 3e094a287526 ("drm/amd/display: Use drm_connector in create_stream_for_sink"). If this is correct, then the 6.1.y series can be brough in sync with cherry-picking the commit and adjust the context around the change. I'm attaching the proposed change. Alex in particular, does that make sense? Regards, Salvatore

[PATCH v2 2/2] hisi_acc_vfio_pci: Add .match_token_uuid callback in hisi_acc_vfio_pci_migrn_ops

by Raghavendra Rao Ananta

The commit, <86624ba3b522> ("vfio/pci: Do vf_token checks for VFIO_DEVICE_BIND_IOMMUFD") accidentally ignored including the .match_token_uuid callback in the hisi_acc_vfio_pci_migrn_ops struct. Introduce the missed callback here.

[PATCH] misc: eeprom/idt_89hpesx: prevent bad user input in idt_dbgfs_csr_write()

by Miaoqian Lin

A malicious user could pass an arbitrarily bad value to memdup_user_nul(), potentially causing kernel crash. This follows the same pattern as commit ee76746387f6 ("netdevsim: prevent bad user input in nsim_dev_health_break_write()") and commit 7ef4c19d245f ("smackfs: restrict bytes count in smackfs write functions") Found via static analysis and code review.
