[PATCH v2] tty: Permit some TIOCL_SETSEL modes without CAP_SYS_ADMIN

by Günther Noack

With this, processes without CAP_SYS_ADMIN are able to use TIOCLINUX with subcode TIOCL_SETSEL, in the selection modes TIOCL_SETPOINTER, TIOCL_SELCLEAR and TIOCL_SELMOUSEREPORT. TIOCL_SETSEL was previously changed to require CAP_SYS_ADMIN, as this IOCTL let callers change the selection buffer and could be used to simulate keypresses. These three TIOCL_SETSEL selection modes, however, are safe to use, as they do not modify the selection buffer. This fixes a mouse support regression that affected Emacs (invisible mouse cursor).

I do not see a good alternative to reorder the code here. We need the data from copy_from_user() in order to know whether the CAP_SYS_ADMIN check even needs to be performed. 2. A previous get_user() from an adjacent memory region already worked (making this a very unlikely failure) I would still appreciate a more formal Tested-by from Hanno (hint, hint) :) --- drivers/tty/vt/selection.c | 14 ++++++++++++++ drivers/tty/vt/vt.c | 2 -- 2 files changed, 14 insertions(+), 2 deletions(-) diff --git a/drivers/tty/vt/selection.c b/drivers/tty/vt/selection.c index 564341f1a74f..0bd6544e30a6 100644 --- a/drivers/tty/vt/selection.c +++ b/drivers/tty/vt/selection.c @@ -192,6 +192,20 @@ int set_selection_user(const struct tiocl_selection __user *sel, if (copy_from_user(&v, sel, sizeof(*sel))) return -EFAULT; + /* + * TIOCL_SELCLEAR, TIOCL_SELPOINTER and TIOCL_SELMOUSEREPORT are OK to + * use without CAP_SYS_ADMIN as they do not modify the selection. + */ + switch (v.sel_mode) { + case TIOCL_SELCLEAR: + case TIOCL_SELPOINTER: + case TIOCL_SELMOUSEREPORT: + break; + default: + if (!capable(CAP_SYS_ADMIN)) + return -EPERM; + } + return set_selection_kernel(&v, tty); } diff --git a/drivers/tty/vt/vt.c b/drivers/tty/vt/vt.c index 96842ce817af..be5564ed8c01 100644 --- a/drivers/tty/vt/vt.c +++ b/drivers/tty/vt/vt.c @@ -3345,8 +3345,6 @@ int tioclinux(struct tty_struct *tty, unsigned long arg) switch (type) { case TIOCL_SETSEL: - if (!capable(CAP_SYS_ADMIN)) - return -EPERM; return set_selection_user(param, tty); case TIOCL_PASTESEL: if (!capable(CAP_SYS_ADMIN)) -- 2.47.1.613.gc27f4b7a9f-goog

[PATCH] mm/cma: add an API to enable/disable concurrent memory allocation for the CMA

by yangge1116＠126.com

From: yangge <yangge1116(a)126.com> Commit 60a60e32cf91 ("Revert "mm/cma.c: remove redundant cma_mutex lock"") simply reverts to the original method of using the cma_mutex to ensure that alloc_contig_range() runs sequentially. This change was made to avoid concurrency allocation failures. However, it can negatively impact performance when concurrent allocation of CMA memory is required. To address this issue, we could introduce an API for concurrency settings, allowing users to decide whether their CMA can perform concurrent memory allocations or not.

f2fs: Introduce linear search for dentries

by Daniel Rosenberg

Commit 91b587ba79e1 ("f2fs: Introduce linear search for dentries") This is a follow up to a patch that previously merged in stable to restore access to files created with emojis under a different hashing scheme. I believe it's relevant for all currently supported stable branches. -Daniel

[PATCH v4 1/5] arm64: errata: Add QCOM_KRYO_4XX_GOLD to the spectre_bhb_k24_list

by Douglas Anderson

Qualcomm Kryo 400-series Gold cores have a derivative of an ARM Cortex A76 in them. Since A76 needs Spectre mitigation via looping then the Kyro 400-series Gold cores also need Spectre mitigation via looping.

While not stated anywhere in the APM, despite stating the ICR is a single 64-bit register, AMD CPUs store the 64-bit ICR as two separate 32-bit values in ICR and ICR2. When IPI virtualization (IPIv on Intel, all AVIC flavors on AMD) is enabled, KVM needs to match CPU behavior as some ICR ICR writes will be handled by the CPU, not by KVM. Add a kvm_x86_ops knob to control the underlying format used by the CPU to store the x2APIC ICR, and tune it to AMD vs. Intel regardless of whether or not x2AVIC is enabled. If KVM is handling all ICR writes, the storage format for x2APIC mode doesn't matter, and having the behavior follow AMD versus Intel will provide better test coverage and ease debugging.

[PATCH 6.1&6.6 0/3] kbuild: Avoid weak external linkage where possible

by Huacai Chen

Backport this series to 6.1&6.6 because LoongArch gets build errors with latest binutils which has commit 599df6e2db17d1c4 ("ld, LoongArch: print error about linking without -fPIC or -fPIE flag in more detail"). CC .vmlinux.export.o UPD include/generated/utsversion.h CC init/version-timestamp.o LD .tmp_vmlinux.kallsyms1 loongarch64-unknown-linux-gnu-ld: kernel/kallsyms.o:(.text+0): relocation R_LARCH_PCALA_HI20 against `kallsyms_markers` can not be used when making a PIE object; recompile with -fPIE loongarch64-unknown-linux-gnu-ld: kernel/crash_core.o:(.init.text+0x984): relocation R_LARCH_PCALA_HI20 against `kallsyms_names` can not be used when making a PIE object; recompile with -fPIE loongarch64-unknown-linux-gnu-ld: kernel/bpf/btf.o:(.text+0xcc7c): relocation R_LARCH_PCALA_HI20 against `__start_BTF` can not be used when making a PIE object; recompile with -fPIE loongarch64-unknown-linux-gnu-ld: BFD (GNU Binutils) 2.43.50.20241126 assertion fail ../../bfd/elfnn-loongarch.c:2673 In theory 5.10&5.15 also need this, but since LoongArch get upstream at 5.19, so I just ignore them because there is no error report about other archs now. Weak external linkage is intended for cases where a symbol reference can remain unsatisfied in the final link. Taking the address of such a symbol should yield NULL if the reference was not satisfied. Given that ordinary RIP or PC relative references cannot produce NULL, some kind of indirection is always needed in such cases, and in position independent code, this results in a GOT entry. In ordinary code, it is arch specific but amounts to the same thing. While unavoidable in some cases, weak references are currently also used to declare symbols that are always defined in the final link, but not in the first linker pass. This means we end up with worse codegen for no good reason. So let's clean this up, by providing preliminary definitions that are only used as a fallback.

[PATCH v2 1/3] misc: pci_endpoint_test: Avoid issue of interrupts remaining after request_irq error

by Kunihiko Hayashi

After devm_request_irq() fails with error, pci_endpoint_test_free_irq_vectors() is called to free allocated vectors with pci_free_irq_vectors(). However some requested IRQs are still allocated, so there are still /proc/irq/* entries remaining and we encounters WARN() with the following message: remove_proc_entry: removing non-empty directory 'irq/30', leaking at least 'pci-endpoint-test.0' WARNING: CPU: 0 PID: 80 at fs/proc/generic.c:717 remove_proc_entry +0x190/0x19c To solve this issue, set the number of remaining IRQs and release the IRQs in advance by calling pci_endpoint_test_release_irq().
