commit a609718 upstream. Prior to Linux v5.4 devtmpfs used mount_single() which treats the given mount options as "remount" options, so it updates the configuration of the single super_block on each mount. Since that was changed, the mount options used for devtmpfs are ignored. This is a regression which affect systemd - which mounts devtmpfs with "-o mode=755,size=4m,nr_inodes=1m". This patch restores the "remount" effect by calling reconfigure_single() Fixes: d401727 ("devtmpfs: don't mix {ramfs,shmem}_fill_super() with mount_single()") Acked-by: Christian Brauner <[email protected]> Cc: Al Viro <[email protected]> Signed-off-by: NeilBrown <[email protected]> Signed-off-by: Linus Torvalds <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>

commit 40a7487 upstream. 'buffer_index_array' really looks like a bitmap. So it should be allocated as such. When kzalloc is called, a number of bytes is expected, but a number of longs is passed instead. In get(), if not enough memory is allocated, un-allocated memory may be read or written. So use bitmap_zalloc() to safely allocate the correct memory size and avoid un-expected behavior. While at it, change the corresponding kfree() into bitmap_free() to keep the semantic.

commit fdc1223 upstream. If the string passed into qcom_pil_info_store() isn't as long as PIL_RELOC_NAME_LEN we'll try to copy the string assuming the length is PIL_RELOC_NAME_LEN to the io space and go beyond the bounds of the string. Let's only copy as many byes as the string is long, ignoring the NUL terminator.

commit ff083a2 upstream. Protect perf_guest_cbs with RCU to fix multiple possible errors. Luckily, all paths that read perf_guest_cbs already require RCU protection, e.g. to protect the callback chains, so only the direct perf_guest_cbs touchpoints need to be modified. Bug Freescale#1 is a simple lack of WRITE_ONCE/READ_ONCE behavior to ensure perf_guest_cbs isn't reloaded between a !NULL check and a dereference. Fixed via the READ_ONCE() in rcu_dereference(). Bug Freescale#2 is that on weakly-ordered architectures, updates to the callbacks themselves are not guaranteed to be visible before the pointer is made visible to readers. Fixed by the smp_store_release() in rcu_assign_pointer() when the new pointer is non-NULL. Bug Freescale#3 is that, because the callbacks are global, it's possible for readers to run in parallel with an unregisters, and thus a module implementing the callbacks can be unloaded while readers are in flight, resulting in a use-after-free. Fixed by a synchronize_rcu() call when unregistering callbacks. Bug Freescale#1 escaped notice because it's extremely unlikely a compiler will reload perf_guest_cbs in this sequence. perf_guest_cbs does get reloaded for future derefs, e.g. for ->is_user_mode(), but the ->is_in_guest() guard all but guarantees the consumer will win the race, e.g. to nullify perf_guest_cbs, KVM has to completely exit the guest and teardown down all VMs before KVM start its module unload / unregister sequence. This also makes it all but impossible to encounter bug Freescale#3. Bug Freescale#2 has not been a problem because all architectures that register callbacks are strongly ordered and/or have a static set of callbacks. But with help, unloading kvm_intel can trigger bug Freescale#1 e.g. wrapping perf_guest_cbs with READ_ONCE in perf_misc_flags() while spamming kvm_intel module load/unload leads to: BUG: kernel NULL pointer dereference, address: 0000000000000000 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 0 P4D 0 Oops: 0000 [Freescale#1] PREEMPT SMP CPU: 6 PID: 1825 Comm: stress Not tainted 5.14.0-rc2+ Freescale#459 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS 0.0.0 02/06/2015 RIP: 0010:perf_misc_flags+0x1c/0x70 Call Trace: perf_prepare_sample+0x53/0x6b0 perf_event_output_forward+0x67/0x160 __perf_event_overflow+0x52/0xf0 handle_pmi_common+0x207/0x300 intel_pmu_handle_irq+0xcf/0x410 perf_event_nmi_handler+0x28/0x50 nmi_handle+0xc7/0x260 default_do_nmi+0x6b/0x170 exc_nmi+0x103/0x130 asm_exc_nmi+0x76/0xbf Fixes: 39447b3 ("perf: Enhance perf to allow for guest statistic collection from host") Signed-off-by: Sean Christopherson <[email protected]> Signed-off-by: Peter Zijlstra (Intel) <[email protected]> Reviewed-by: Paolo Bonzini <[email protected]> Cc: [email protected] Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Greg Kroah-Hartman <[email protected]>
…up() commit 5c7df80 upstream. Wait to register perf callbacks until after doing vendor hardaware setup. VMX's hardware_setup() configures Intel Processor Trace (PT) mode, and a future fix to register the Intel PT guest interrupt hook if and only if Intel PT is exposed to the guest will consume the configured PT mode. Delaying registration to hardware setup is effectively a nop as KVM's perf hooks all pivot on the per-CPU current_vcpu, which is non-NULL only when KVM is handling an IRQ/NMI in a VM-Exit path. I.e. current_vcpu will be NULL throughout both kvm_arch_init() and kvm_arch_hardware_setup().

commit 812de04 upstream. With KVM_CAP_S390_USER_SIGP, there are only five Signal Processor orders (CONDITIONAL EMERGENCY SIGNAL, EMERGENCY SIGNAL, EXTERNAL CALL, SENSE, and SENSE RUNNING STATUS) which are intended for frequent use and thus are processed in-kernel. The remainder are sent to userspace with the KVM_CAP_S390_USER_SIGP capability. Of those, three orders (RESTART, STOP, and STOP AND STORE STATUS) have the potential to inject work back into the kernel, and thus are asynchronous. Let's look for those pending IRQs when processing one of the in-kernel SIGP orders, and return BUSY (CC2) if one is in process. This is in agreement with the Principles of Operation, which states that only one order can be "active" on a CPU at a time.

The 9P2000 setattr method v9fs_vfs_setattr() method gets this right. Check whether struct iattr fields are valid first before copying in v9fs_vfs_setattr_dotl() too and make sure that all other fields are set to 0 apart from {g,u}id which should be set to INVALID_{G,U}ID.

commit 0499f41 upstream. The vga16fb framebuffer driver only supports Enhanced Graphics Adapter (EGA) and Video Graphics Array (VGA) 16 color graphic cards. But it doesn't check if the adapter is one of those or if a VGA16 mode is used. This means that the driver will be probed even if a VESA BIOS Extensions (VBE) or Graphics Output Protocol (GOP) interface is used. This issue has been present for a long time but it was only exposed by commit d391c58 ("drivers/firmware: move x86 Generic System Framebuffers support") since the platform device registration to match the {vesa,efi}fb drivers is done later as a consequence of that change. All non-x86 architectures though treat orig_video_isVGA as a boolean so only do the supported video mode check for x86 and not for other arches.

…ecursive functions commit d5962fb upstream. In 'perf report', entering a recursive function from inside of itself (either directly of indirectly through some other function) results in calling symbol__annotate2 multiple() times, and freeing the whole disassembly when exiting from the innermost instance. The first issue causes the function's disassembly to be duplicated, and the latter a heap use-after-free (and crash) when trying to access the disassembly again. I reproduced the bug on perf 5.11.22 (Ubuntu 20.04.3 LTS) and 5.16.rc8 with the following testcase (compile with gcc recursive.c -o recursive). To reproduce: - perf record ./recursive - perf report - enter fibonacci and annotate it - move the cursor on one of the "callq fibonacci" instructions and press enter - at this point there will be two copies of the function in the disassembly - go back by pressing q, and perf will crash #include <stdio.h> int fibonacci(int n) { if(n <= 2) return 1; return fibonacci(n-1) + fibonacci(n-2); } int main() { printf("%d\n", fibonacci(40)); } This patch addresses the issue by annotating a function and freeing the associated memory on exit only if no annotation is already present, so that a recursive function is only annotated on entry.

…fter reboot from Windows commit c193300 upstream. This patch addresses an issue where after rebooting from Windows into Linux there would be no audio output. It turns out that the Realtek Audio driver on Windows changes some coeffs which are not being reset/reinitialized when rebooting the machine. As a result, there is no audio output until these coeffs are being reset to their initial state. This patch takes care of that by setting known-good (initial) values to the coeffs. We initially relied upon alc1220_fixup_clevo_p950() to fix some pins in the connection list. However, it also sets coef 0x7 which does not need to be touched. Furthermore, to prevent mixing device-specific quirks I introduced a new alc1220_fixup_gb_x570() which is heavily based on alc1220_fixup_clevo_p950() but does not set coeff 0x7 and fixes the coeffs that are actually needed instead. This new alc1220_fixup_gb_x570() is believed to also work for other boards, like the Gigabyte X570 Aorus Extreme and the newer Gigabyte Aorus X570S Master. However, as there is no way for me to test these I initially only enable this new behaviour for the mainboard I have which is the Gigabyte X570(non-S) Aorus Master. I tested this patch on the 5.15 branch as well as on master and it is working well for me.

commit 603362b upstream. drivers/mtd/maps/ixp4xx.c requires MTD_CFI_BE_BYTE_SWAP to be set in order to compile. drivers/mtd/maps/ixp4xx.c:57:4: error: #error CONFIG_MTD_CFI_BE_BYTE_SWAP required This patch avoids the #error output by enforcing the policy in Kconfig. Not sure if this is the right approach, but it helps doing randconfig builds.
