2024-03-26x86/efistub: Add missing boot_params for mixed mode compat entryArd Biesheuvel1-5/+15
The pure EFI stub entry point does not take a struct boot_params from the boot loader, but creates it from scratch, and populates only the fields that still have meaning in this context (command line, initrd base and size, etc) The original mixed mode implementation used the EFI handover protocol instead, where the boot loader (i.e., GRUB) populates a boot_params struct and passes it to a special Linux specific EFI entry point that takes the boot_params pointer as its third argument. When the new mixed mode implementation was introduced, using a special 32-bit PE entrypoint in the 64-bit kernel, it adopted the pure approach, and relied on the EFI stub to create the struct boot_params. This is preferred because it makes the bootloader side much easier to implement, as it does not need any x86-specific knowledge on how struct boot_params and struct setup_header are put together. This mixed mode implementation was adopted by systemd-boot version 252 and later. When commit e2ab9eab324c ("x86/boot/compressed: Move 32-bit entrypoint code into .text section") refactored this code and moved it out of head_64.S, the fact that ESI was populated with the address of the base of the image was overlooked, and to simplify the code flow, ESI is now zeroed and stored to memory unconditionally in shared code, so that the NULL-ness of that variable can still be used later to determine which mixed mode boot protocol is in use. With ESI pointing to the base of the image, it can serve as a struct boot_params pointer for startup_32(), which only accesses the init_data and kernel_alignment fields (and the scratch field as a temporary stack). Zeroing ESI means that those accesses produce garbage now, even though things appear to work if the first page of memory happens to be zeroed, and the region right before LOAD_PHYSICAL_ADDR (== 16 MiB) happens to be free. The solution is to pass a special, temporary struct boot_params to startup_32() via ESI, one that is sufficient for getting it to create the page tables correctly and is discarded right after. This involves setting a minimal alignment of 4k, only to get the statically allocated page tables line up correctly, and setting init_size to the executable image size (_end - startup_32). This ensures that the page tables are covered by the static footprint of the PE image. Given that EFI boot no longer calls the decompressor and no longer pads the image to permit the decompressor to execute in place, the same temporary struct boot_params should be used in the EFI handover protocol based mixed mode implementation as well, to prevent the page tables from being placed outside of allocated memory.

2024-03-25tcp: properly terminate timers for kernel socketsEric Dumazet4-0/+24
We had various syzbot reports about tcp timers firing after the corresponding netns has been dismantled. Fortunately Josef Bacik could trigger the issue more often, and could test a patch I wrote two years ago. When TCP sockets are closed, we call inet_csk_clear_xmit_timers() to 'stop' the timers. inet_csk_clear_xmit_timers() can be called from any context, including when socket lock is held. This is the reason it uses sk_stop_timer(), aka del_timer(). This means that ongoing timers might finish much later. For user sockets, this is fine because each running timer holds a reference on the socket, and the user socket holds a reference on the netns. For kernel sockets, we risk that the netns is freed before timer can complete, because kernel sockets do not hold reference on the netns. This patch adds inet_csk_clear_xmit_timers_sync() function that using sk_stop_timer_sync() to make sure all timers are terminated before the kernel socket is released. Modules using kernel sockets close them in their netns exit() handler. Also add sock_not_owned_by_me() helper to get LOCKDEP support : inet_csk_clear_xmit_timers_sync() must not be called while socket lock is held. It is very possible we can revert in the future commit 3a58f13a881e ("net: rds: acquire refcount on TCP sockets") which attempted to solve the issue in rds only. (net/smc/af_smc.c and net/mptcp/subflow.c have similar code) We probably can remove the check_net() tests from tcp_out_of_resources() and __tcp_close() in the future.

commit e748d0fd66ab ("net: hsr: Disable promiscuous mode in offload mode") disables promiscuous mode of slave devices while creating an HSR interface. But while deleting the HSR interface, it does not take care of it. It decreases the promiscuous mode count, which eventually enables promiscuous mode on the slave devices when creating HSR interface again. Fix this by not decrementing the promiscuous mode count while deleting the HSR interface when offload is enabled.

2024-03-25s390/qeth: handle deferred cc1Alexandra Winter1-2/+36
The IO subsystem expects a driver to retry a ccw_device_start, when the subsequent interrupt response block (irb) contains a deferred condition code 1. Symptoms before this commit: On the read channel we always trigger the next read anyhow, so no different behaviour here. On the write channel we may experience timeout errors, because the expected reply will never be received without the retry. Other callers of qeth_send_control_data() may wrongly assume that the ccw was successful, which may cause problems later. Note that since commit 2297791c92d0 ("s390/cio: dont unregister subchannel from child-drivers") and commit 5ef1dc40ffa6 ("s390/cio: fix invalid -EBUSY on ccw_device_start") deferred CC1s are much more likely to occur.

2024-03-25genirq: Introduce IRQF_COND_ONESHOT and use it in pinctrl-amdRafael J. Wysocki3-3/+11
There is a problem when a driver requests a shared interrupt line to run a threaded handler on it without IRQF_ONESHOT set if that flag has been set already for the IRQ in question by somebody else. Namely, the request fails which usually leads to a probe failure even though the driver might have worked just fine with IRQF_ONESHOT, but it does not want to use it by default. Currently, the only way to handle this is to try to request the IRQ without IRQF_ONESHOT, but with IRQF_PROBE_SHARED set and if this fails, try again with IRQF_ONESHOT set. However, this is a bit cumbersome and not very clean. When commit 7a36b901a6eb ("ACPI: OSL: Use a threaded interrupt handler for SCI") switched the ACPI subsystem over to using a threaded interrupt handler for the SCI, it had to use IRQF_ONESHOT for it because that's required due to the way the SCI handler works (it needs to walk all of the enabled GPEs before the interrupt line can be unmasked). The SCI interrupt line is not shared with other users very often due to the SCI handling overhead, but on sone systems it is shared and when the other user of it attempts to install a threaded handler, a flags mismatch related to IRQF_ONESHOT may occur. As it turned out, that happened to the pinctrl-amd driver and so commit 4451e8e8415e ("pinctrl: amd: Add IRQF_ONESHOT to the interrupt request") attempted to address the issue by adding IRQF_ONESHOT to the interrupt flags in that driver, but this is now causing an IRQF_ONESHOT-related mismatch to occur on another system which cannot boot as a result of it. Clearly, pinctrl-amd can work with IRQF_ONESHOT if need be, but it should not set that flag by default, so it needs a way to indicate that to the interrupt subsystem. To that end, introdcuce a new interrupt flag, IRQF_COND_ONESHOT, which will only have effect when the IRQ line is shared and IRQF_ONESHOT has been set for it already, in which case it will be promoted to the latter.

2024-03-25scsi: core: Fix unremoved procfs host directory regressionGuilherme G. Piccoli1-3/+4
Commit fc663711b944 ("scsi: core: Remove the /proc/scsi/${proc_name} directory earlier") fixed a bug related to modules loading/unloading, by adding a call to scsi_proc_hostdir_rm() on scsi_remove_host(). But that led to a potential duplicate call to the hostdir_rm() routine, since it's also called from scsi_host_dev_release(). That triggered a regression report, which was then fixed by commit be03df3d4bfe ("scsi: core: Fix a procfs host directory removal regression"). The fix just dropped the hostdir_rm() call from dev_release(). But it happens that this proc directory is created on scsi_host_alloc(), and that function "pairs" with scsi_host_dev_release(), while scsi_remove_host() pairs with scsi_add_host(). In other words, it seems the reason for removing the proc directory on dev_release() was meant to cover cases in which a SCSI host structure was allocated, but the call to scsi_add_host() didn't happen. And that pattern happens to exist in some error paths, for example. Syzkaller causes that by using USB raw gadget device, error'ing on usb-storage driver, at usb_stor_probe2(). By checking that path, we can see that the BadDevice label leads to a scsi_host_put() after a SCSI host allocation, but there's no call to scsi_add_host() in such path. That leads to messages like this in dmesg (and a leak of the SCSI host proc structure): usb-storage 4-1:87.51: USB Mass Storage device detected proc_dir_entry 'scsi/usb-storage' already registered WARNING: CPU: 1 PID: 3519 at fs/proc/generic.c:377 proc_register+0x347/0x4e0 fs/proc/generic.c:376 The proper fix seems to still call scsi_proc_hostdir_rm() on dev_release(), but guard that with the state check for SHOST_CREATED; there is even a comment in scsi_host_dev_release() detailing that: such conditional is meant for cases where the SCSI host was allocated but there was no calls to {add,remove}_host(), like the usb-storage case. This is what we propose here and with that, the error path of usb-storage does not trigger the warning anymore.

2024-03-25scsi: sd: Fix TCG OPAL unlock on system resumeDamien Le Moal7-5/+69
Commit 3cc2ffe5c16d ("scsi: sd: Differentiate system and runtime start/stop management") introduced the manage_system_start_stop scsi_device flag to allow libata to indicate to the SCSI disk driver that nothing should be done when resuming a disk on system resume. This change turned the execution of sd_resume() into a no-op for ATA devices on system resume. While this solved deadlock issues during device resume, this change also wrongly removed the execution of opal_unlock_from_suspend(). As a result, devices with TCG OPAL locking enabled remain locked and inaccessible after a system resume from sleep. To fix this issue, introduce the SCSI driver resume method and implement it with the sd_resume() function calling opal_unlock_from_suspend(). The former sd_resume() function is renamed to sd_resume_common() and modified to call the new sd_resume() function. For non-ATA devices, this result in no functional changes. In order for libata to explicitly execute sd_resume() when a device is resumed during system restart, the function scsi_resume_device() is introduced. libata calls this function from the revalidation work executed on devie resume, a state that is indicated with the new device flag ATA_DFLAG_RESUMING. Doing so, locked TCG OPAL enabled devices are unlocked on resume, allowing normal operation.

2024-03-25riscv, bpf: Fix kfunc parameters incompatibility between bpf and riscv abiPu Lehui1-0/+16
We encountered a failing case when running selftest in no_alu32 mode: The failure case is `kfunc_call/kfunc_call_test4` and its source code is like bellow: ``` long bpf_kfunc_call_test4(signed char a, short b, int c, long d) __ksym; int kfunc_call_test4(struct __sk_buff *skb) { ... tmp = bpf_kfunc_call_test4(-3, -30, -200, -1000); ... } ``` And its corresponding asm code is: ``` 0: r1 = -3 1: r2 = -30 2: r3 = 0xffffff38 # opcode: 18 03 00 00 38 ff ff ff 00 00 00 00 00 00 00 00 4: r4 = -1000 5: call bpf_kfunc_call_test4 ``` insn 2 is parsed to ld_imm64 insn to emit 0x00000000ffffff38 imm, and converted to int type and then send to bpf_kfunc_call_test4. But since it is zero-extended in the bpf calling convention, riscv jit will directly treat it as an unsigned 32-bit int value, and then fails with the message "actual 4294966063 != expected -1234". The reason is the incompatibility between bpf and riscv abi, that is, bpf will do zero-extension on uint, but riscv64 requires sign-extension on int or uint. We can solve this problem by sign extending the 32-bit parameters in kfunc. The issue is related to [0], and thanks to Yonghong and Alexei.

2024-03-25RAS/AMD/FMPM: Safely handle saved records of various sizesYazen Ghannam1-18/+37
Currently, the size of the locally cached FRU record structures is based on the module parameter "max_nr_entries". This creates issues when restoring records if a user changes the parameter. If the number of entries is reduced, then old, larger records will not be restored. The opportunity to take action on the saved data is missed. Also, new records will be created and written to storage, even as the old records remain in storage, resulting in wasted space. If the number of entries is increased, then the length of the old, smaller records will not be adjusted. This causes a checksum failure which leads to the old record being cleared from storage. Again this results in another missed opportunity for action on the saved data. Allocate the temporary record with the maximum possible size based on the current maximum number of supported entries (255). This allows the ERST read operation to succeed if max_nr_entries has been increased. Warn the user if a saved record exceeds the expected size and fail to load the module. This allows the user to adjust the module parameter without losing data or the opportunity to restore larger records. Increase the size of a saved record up to the current max_rec_len. The checksum will be recalculated, and the updated record will be written to storage.

2024-03-25ice: fix memory corruption bug with suspend and rebuildJesse Brandeburg1-9/+9
The ice driver would previously panic after suspend. This is caused from the driver *only* calling the ice_vsi_free_q_vectors() function by itself, when it is suspending. Since commit b3e7b3a6ee92 ("ice: prevent NULL pointer deref during reload") the driver has zeroed out num_q_vectors, and only restored it in ice_vsi_cfg_def(). This further causes the ice_rebuild() function to allocate a zero length buffer, after which num_q_vectors is updated, and then the new value of num_q_vectors is used to index into the zero length buffer, which corrupts memory. The fix entails making sure all the code referencing num_q_vectors only does so after it has been reset via ice_vsi_cfg_def(). I didn't perform a full bisect, but I was able to test against 6.1.77 kernel and that ice driver works fine for suspend/resume with no panic, so sometime since then, this problem was introduced.

2024-03-25ice: Refactor FW data type and fix bitmap casting issueSteven Zou4-15/+20
According to the datasheet, the recipe association data is an 8-byte little-endian value. It is described as 'Bitmap of the recipe indexes associated with this profile', it is from 24 to 31 byte area in FW. Therefore, it is defined to '__le64 recipe_assoc' in struct ice_aqc_recipe_to_profile. And then fix the bitmap casting issue, as we must never ever use castings for bitmap type.
