2021-02-11tracing: Check length before giving out the filter bufferSteven Rostedt (VMware)
When filters are used by trace events, a page is allocated on each CPU and used to copy the trace event fields to this page before writing to the ring buffer. The reason to use the filter and not write directly into the ring buffer is because a filter may discard the event and there's more overhead on discarding from the ring buffer than the extra copy. The problem here is that there is no check against the size being allocated when using this page. If an event asks for more than a page size while being filtered, it will get only a page, leading to the caller writing more that what was allocated. Check the length of the request, and if it is more than PAGE_SIZE minus the header default back to allocating from the ring buffer directly. The ring buffer may reject the event if its too big anyway, but it wont overflow.

2021-02-12kbuild: fix CONFIG_TRIM_UNUSED_KSYMS build for ppc64Masahiro Yamada
Stephen Rothwell reported a build error on ppc64 when CONFIG_TRIM_UNUSED_KSYMS is enabled. Jessica Yu pointed out the cause of the error with the reference to the ppc64 ELF ABI: "Symbol names with a dot (.) prefix are reserved for holding entry point addresses. The value of a symbol named ".FN", if it exists, is the entry point of the function "FN". As it turned out, CONFIG_TRIM_UNUSED_KSYMS has never worked for ppc64, but this issue has been unnoticed until recently because this option depends on !UNUSED_SYMBOLS hence is disabled by all{mod,yes}config. (Then, it was uncovered by another patch removing UNUSED_SYMBOLS.) Removing the dot prefix in scripts/gen_autoksyms.sh fixes the issue. Please note it must be done before 'sort -u' because modules have both ._mcount and _mcount undefined when CONFIG_FUNCTION_TRACER=y.

2021-02-11coresight: etm-perf: Support PID tracing for kernel at EL2Suzuki K Poulose
When the kernel is running at EL2, the PID is stored in CONTEXTIDR_EL2. So, tracing CONTEXTIDR_EL1 doesn't give us the pid of the process. Thus we should trace the VMID with VMIDOPT set to trace CONTEXTIDR_EL2 instead of CONTEXTIDR_EL1. Given that we have an existing config option "contextid" and this will be useful for tracing virtual machines (when we get to support virtualization). So instead, this patch extends option CTXTID with an extra bit ETM_OPT_CTXTID2 (bit 15), thus on an EL2 kernel, we will have another bit available for the perf tool: ETM_OPT_CTXTID is for kernel running in EL1, ETM_OPT_CTXTID2 is used when kernel runs in EL2 with VHE enabled. The tool must be backward compatible for users, i.e, "contextid" today traces PID and that should remain the same; for this purpose, the perf tool is updated to automatically set corresponding bit for the "contextid" config, therefore, the user doesn't have to bother which EL the kernel is running. i.e, perf record -e cs_etm/contextid/u -- will always do the "pid" tracing, independent of the kernel EL. The driver parses the format "contextid", which traces CONTEXTIDR_EL1 for ETM_OPT_CTXTID (on EL1 kernel) and traces CONTEXTIDR_EL2 for ETM_OPT_CTXTID2 (on EL2 kernel). Besides the enhancement for format "contexid", extra two formats are introduced: "contextid1" and "contextid2". This considers to support tracing both CONTEXTIDR_EL1 and CONTEXTIDR_EL2 when the kernel is running at EL2. Finally, the PMU formats are defined as follow: "contextid1": Available on both EL1 kernel and EL2 kernel. When the kernel is running at EL1, "contextid1" enables the PID tracing; when the kernel is running at EL2, this enables tracing the PID of guest applications. "contextid2": Only usable when the kernel is running at EL2. When selected, enables PID tracing on EL2 kernel. "contextid": Will be an alias for the option that enables PID tracing. I.e, contextid == contextid1, on EL1 kernel. contextid == contextid2, on EL2 kernel.

2021-02-11coresight: etm-perf: Clarify comment on perf optionsLeo Yan
In theory, the options should be arbitrary values and are neutral for any ETM version; so far perf tool uses ETMv3.5/PTM ETMCR config bits except for register's bit definitions, also uses as options. This can introduce confusion, especially if we want to add a new option but the new option is not supported by ETMv3.5/PTM ETMCR. But on the other hand, we cannot change options since these options are generic CoreSight PMU ABI. For easier maintenance and avoid confusion, this patch refines the comment to clarify perf options, and gives out the background info for these bits are coming from ETMv3.5/PTM. Afterwards, we should take these options as general knobs, and if there have any confliction with ETMv3.5/PTM, should consider to define saperate macros for ETMv3.5/PTM ETMCR config bits.

2021-02-11cifs: Set CIFS_MOUNT_USE_PREFIX_PATH flag on setting cifs_sb->prepath.Shyam Prasad N
While debugging another issue today, Steve and I noticed that if a subdir for a file share is already mounted on the client, any new mount of any other subdir (or the file share root) of the same share results in sharing the cifs superblock, which e.g. can result in incorrect device name. While setting prefix path for the root of a cifs_sb, CIFS_MOUNT_USE_PREFIX_PATH flag should also be set. Without it, prepath is not even considered in some places, and output of "mount" and various /proc/<>/*mount* related options can be missing part of the device name.

2021-02-11xfs: consider shutdown in bmapbt cursor delete assertBrian Foster
The assert in xfs_btree_del_cursor() checks that the bmapbt block allocation field has been handled correctly before the cursor is freed. This field is used for accurate calculation of indirect block reservation requirements (for delayed allocations), for example. generic/019 reproduces a scenario where this assert fails because the filesystem has shutdown while in the middle of a bmbt record insertion. This occurs after a bmbt block has been allocated via the cursor but before the higher level bmap function (i.e. xfs_bmap_add_extent_hole_real()) completes and resets the field. Update the assert to accommodate the transient state if the filesystem has shutdown. While here, clean up the indentation and comments in the function.
