2022-02-02drm/amdgpu: Add judgement to avoid infinite loopyipechai
1. The infinite loop causing soft lock occurs on multiple amdgpu cards supporting ras feature. 2. This a workaround patch to fix 6492e1b07c03397f85bd6dc0e230ea6cd9394635. It is valid for multiple amdgpu cards of the same type. 3. The root cause is that each GPU card device has a separate .ras_list link header, but the instance and linked list node of each ras block are unique. When each device is initialized, each ras instance will repeatedly add link node to the device every time. In this way, only the .ras_list of the last initialized device is completely correct. the .ras_list->prev and .ras_list->next of the device initialzied before can still point to the correct ras instance, but the prev pointer and next pointer of the pointed ras instance both point to the last initialized device's .ras_ list instead of the beginning .ras_ list. When using list_for_each_entry_safe searches for non-existent Ras nodes on devices other than the last device, the last ras instance next pointer cannot always be equal to the beginning .ras_list, so that the loop cannot be terminated, the program enters a infinite loop. BTW: Since the data and initialization process of each card are the same, the link list between ras instances will not be destroyed every time the device is initialized. 4. The soft locked logs are as follows: [ 262.165690] CPU: 93 PID: 758 Comm: kworker/93:1 Tainted: G OE 5.13.0-27-generic #29~20.04.1-Ubuntu [ 262.165695] Hardware name: Supermicro AS -4124GS-TNR/H12DSG-O-CPU, BIOS T20200717143848 07/17/2020 [ 262.165698] Workqueue: events amdgpu_ras_do_recovery [amdgpu] [ 262.165980] RIP: 0010:amdgpu_ras_get_ras_block+0x86/0xd0 [amdgpu] [ 262.166239] Code: 68 d8 4c 8d 71 d8 48 39 c3 74 54 49 8b 45 38 48 85 c0 74 32 44 89 fa 44 89 e6 4c 89 ef e8 82 e4 9b dc 85 c0 74 3c 49 8b 46 28 <49> 8d 56 28 4d 89 f5 48 83 e8 28 48 39 d3 74 25 49 89 c6 49 8b 45 [ 262.166243] RSP: 0018:ffffac908fa87d80 EFLAGS: 00000202 [ 262.166247] RAX: ffffffffc1394248 RBX: ffff91e4ab8d6e20 RCX: ffffffffc1394248 [ 262.166249] RDX: ffff91e4aa356e20 RSI: 000000000000000e RDI: ffff91e4ab8c0000 [ 262.166252] RBP: ffffac908fa87da8 R08: 0000000000000007 R09: 0000000000000001 [ 262.166254] R10: ffff91e4930b64ec R11: 0000000000000000 R12: 000000000000000e [ 262.166256] R13: ffff91e4aa356df8 R14: ffffffffc1394320 R15: 0000000000000003 [ 262.166258] FS: 0000000000000000(0000) GS:ffff92238fb40000(0000) knlGS:0000000000000000 [ 262.166261] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 262.166264] CR2: 00000001004865d0 CR3: 000000406d796000 CR4: 0000000000350ee0 [ 262.166267] Call Trace: [ 262.166272] amdgpu_ras_do_recovery+0x130/0x290 [amdgpu] [ 262.166529] ? psi_task_switch+0xd2/0x250 [ 262.166537] ? __switch_to+0x11d/0x460 [ 262.166542] ? __switch_to_asm+0x36/0x70 [ 262.166549] process_one_work+0x220/0x3c0 [ 262.166556] worker_thread+0x4d/0x3f0 [ 262.166560] ? process_one_work+0x3c0/0x3c0 [ 262.166563] kthread+0x12b/0x150 [ 262.166568] ? set_kthread_struct+0x40/0x40 [ 262.166571] ret_from_fork+0x22/0x30 Fixes: 6492e1b07c0339 ("drm/amdgpu: Unify ras block interface for each ras block") Signed-off-by: yipechai <YiPeng.Chai@amd.com> Reviewed-by: John Clements <john.clements@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2022-02-02x86/bug: Merge annotate_reachable() into _BUG_FLAGS() asmNick Desaulniers
In __WARN_FLAGS(), we had two asm statements (abbreviated): asm volatile("ud2"); asm volatile(".pushsection .discard.reachable"); These pair of statements are used to trigger an exception, but then help objtool understand that for warnings, control flow will be restored immediately afterwards. The problem is that volatile is not a compiler barrier. GCC explicitly documents this: > Note that the compiler can move even volatile asm instructions > relative to other code, including across jump instructions. Also, no clobbers are specified to prevent instructions from subsequent statements from being scheduled by compiler before the second asm statement. This can lead to instructions from subsequent statements being emitted by the compiler before the second asm statement. Providing a scheduling model such as via -march= options enables the compiler to better schedule instructions with known latencies to hide latencies from data hazards compared to inline asm statements in which latencies are not estimated. If an instruction gets scheduled by the compiler between the two asm statements, then objtool will think that it is not reachable, producing a warning. To prevent instructions from being scheduled in between the two asm statements, merge them. Also remove an unnecessary unreachable() asm annotation from BUG() in favor of __builtin_unreachable(). objtool is able to track that the ud2 from BUG() terminates control flow within the function.

Windows has a system-wide "dummy" page that may be mapped into the destination buffer (potentially more than once into the same buffer) by the Windows Memory Manager in an effort to generate a single large I/O [1][2]. QEMU makes a point of preserving overlap relationships when cloning I/O vectors, so krbd gets exposed to this behaviour.

2022-02-02libceph: make recv path in secure mode work the same as send pathIlya Dryomov
The recv path of secure mode is intertwined with that of crc mode. While it's slightly more efficient that way (the ciphertext is read into the destination buffer and decrypted in place, thus avoiding two potentially heavy memory allocations for the bounce buffer and the corresponding sg array), it isn't really amenable to changes. Sacrifice that edge and align with the send path which always uses a full-sized bounce buffer (currently there is no other way -- if the kernel crypto API ever grows support for streaming (piecewise) en/decryption for GCM [1], we would be able to easily take advantage of that on both sides).

2022-02-02ima: Allow template selection with ima_template[_fmt]= after ima_hash=Roberto Sassu
Commit c2426d2ad5027 ("ima: added support for new kernel cmdline parameter ima_template_fmt") introduced an additional check on the ima_template variable to avoid multiple template selection. Unfortunately, ima_template could be also set by the setup function of the ima_hash= parameter, when it calls ima_template_desc_current(). This causes attempts to choose a new template with ima_template= or with ima_template_fmt=, after ima_hash=, to be ignored. Achieve the goal of the commit mentioned with the new static variable template_setup_done, so that template selection requests after ima_hash= are not ignored. Finally, call ima_init_template_list(), if not already done, to initialize the list of templates before lookup_template_desc() is called.

2022-02-02drm/i915: Only include i915_reg.h from .c filesMatt Roper
Several of our i915 header files, have been including i915_reg.h. This means that any change to i915_reg.h will trigger a full rebuild of pretty much every file of the driver, even those that don't have any kind of register access. Let's delete the i915_reg.h include from all headers and add an explicit include from the .c files that truly need the register definitions; those that need a definition of i915_reg_t for a function definition can get it from i915_reg_defs.h instead. We also remove two non-register #define's (VLV_DISPLAY_BASE and GEN12_SFC_DONE_MAX) into i915_reg_defs.h to allow us to drop the i915_reg.h include from a couple of headers. There's probably a lot more header dependency optimization possible, but the changes here roughly cut the number of files compiled after 'touch i915_reg.h' in half --- a good first step.

2022-02-02drm/i915: Parameterize MI_PREDICATE registersMatt Roper
The various MI_PREDICATE registers have per-engine instances. Today we only utilize the RCS0 instance of each, but that will likely change in the future; switch to parameterized register definitions to make these easier to work with going forward. Of special note is MI_PREDICATE_RESULT_2; we only use it in one place in the driver today in HSW-specific code. It turns out that the bspec (page 94) lists two different offsets for this register on HSW; one is in the standard location shared by all other platforms (base + 0x3bc) and the other is an unusual location (0x2214). We're using the second, non-standard offset in i915 today; that offset doesn't exist on any other platforms (and it's not even 100% clear that it's correct for HSW) so I've renamed the current non-standard definition to HSW_MI_PREDICATE_RESULT_2; the new cross-platform parameterized macro (which is still unused at the moment) uses the standard offset.

This makes the code more similar to how we handle things like multicast register ranges, forcewake tables, shadow tables, etc. and also lets us avoid needing symbolic register name definitions for the various range end points.

2022-02-02Partially revert "net/smc: Add netlink net namespace support"Dmitry V. Levin
The change of sizeof(struct smc_diag_linkinfo) by commit 79d39fc503b4 ("net/smc: Add netlink net namespace support") introduced an ABI regression: since struct smc_diag_lgrinfo contains an object of type "struct smc_diag_linkinfo", offset of all subsequent members of struct smc_diag_lgrinfo was changed by that change. As result, applications compiled with the old version of struct smc_diag_linkinfo will receive garbage in struct smc_diag_lgrinfo.role if the kernel implements this new version of struct smc_diag_linkinfo. Fix this regression by reverting the part of commit 79d39fc503b4 that changes struct smc_diag_linkinfo. After all, there is SMC_GEN_NETLINK interface which is good enough, so there is probably no need to touch the smc_diag ABI in the first place.
