2022-07-17init: add "hostname" kernel parameterDan Moulding1-0/+13
The gethostname system call returns the hostname for the current machine. However, the kernel has no mechanism to initially set the current machine's name in such a way as to guarantee that the first userspace process to call gethostname will receive a meaningful result. It relies on some unspecified userspace process to first call sethostname before gethostname can produce a meaningful name. Traditionally the machine's hostname is set from userspace by the init system. The init system, in turn, often relies on a configuration file (say, /etc/hostname) to provide the value that it will supply in the call to sethostname. Consequently, the file system containing /etc/hostname usually must be available before the hostname will be set. There may, however, be earlier userspace processes that could call gethostname before the file system containing /etc/hostname is mounted. Such a process will get some other, likely meaningless, name from gethostname (such as "(none)", "localhost", or "darkstar"). A real-world example where this can happen, and lead to undesirable results, is with mdadm. When assembling arrays, mdadm distinguishes between "local" arrays and "foreign" arrays. A local array is one that properly belongs to the current machine, and a foreign array is one that is (possibly temporarily) attached to the current machine, but properly belongs to some other machine. To determine if an array is local or foreign, mdadm may compare the "homehost" recorded on the array with the current hostname. If mdadm is run before the root file system is mounted, perhaps because the root file system itself resides on an md-raid array, then /etc/hostname isn't yet available and the init system will not yet have called sethostname, causing mdadm to incorrectly conclude that all of the local arrays are foreign. Solving this problem *could* be delegated to the init system. It could be left up to the init system (including any init system that starts within an initramfs, if one is in use) to ensure that sethostname is called before any other userspace process could possibly call gethostname. However, it may not always be obvious which processes could call gethostname (for example, udev itself might not call gethostname, but it could via udev rules invoke processes that do). Additionally, the init system has to ensure that the hostname configuration value is stored in some place where it will be readily accessible during early boot. Unfortunately, every init system will attempt to (or has already attempted to) solve this problem in a different, possibly incorrect, way. This makes getting consistently working configurations harder for users. I believe it is better for the kernel to provide the means by which the hostname may be set early, rather than making this a problem for the init system to solve. The option to set the hostname during early startup, via a kernel parameter, provides a simple, reliable way to solve this problem. It also could make system configuration easier for some embedded systems.

Currently unpoison_memory(unsigned long pfn) is designed for soft poison(hwpoison-inject) only. Since 17fae1294ad9d, the KPTE gets cleared on a x86 platform once hardware memory corrupts. Unpoisoning a hardware corrupted page puts page back buddy only, the kernel has a chance to access the page with *NOT PRESENT* KPTE. This leads BUG during accessing on the corrupted KPTE.

The netfs_io_request cleanup op is now always in a position to be given a pointer to a netfs_io_request struct, so this can be passed in instead of the mapping and private data arguments (both of which are included in the struct). So rename the ->cleanup op to ->free_request (to match ->init_request) and pass in the I/O pointer.

2022-06-10netfs: Further cleanups after struct netfs_inode wrapper introducedLinus Torvalds1-4/+5
Change the signature of netfs helper functions to take a struct netfs_inode pointer rather than a struct inode pointer where appropriate, thereby relieving the need for the network filesystem to convert its internal inode format down to the VFS inode only for netfslib to bounce it back up. For type safety, it's better not to do that (and it's less typing too). Give netfs_write_begin() an extra argument to pass in a pointer to the netfs_inode struct rather than deriving it internally from the file pointer. Note that the ->write_begin() and ->write_end() ops are intended to be replaced in the future by netfslib code that manages this without the need to call in twice for each page. netfs_readpage() and similar are intended to be pointed at directly by the address_space_operations table, so must stick to the signature dictated by the function pointers there.

As Liviu pointed out, the arm,malidp-arqos-high-level property mentioned in the original .txt binding was a mistake, and arm,malidp-arqos-value needs to take its place. The binding commit ce6eb0253cba ("dt/bindings: display: Add optional property node define for Mali DP500") mentions the right name in the commit message, but has the wrong name in the diff. Commit d298e6a27a81 ("drm/arm/mali-dp: Add display QoS interface configuration for Mali DP500") uses the property in the driver, but uses the shorter name. Remove the wrong property from the binding, and use the proper name in the example. The actual property was already documented properly.

2022-06-09netfs: Fix gcc-12 warning by embedding vfs inode in netfs_i_contextDavid Howells1-19/+18
While randstruct was satisfied with using an open-coded "void *" offset cast for the netfs_i_context <-> inode casting, __builtin_object_size() as used by FORTIFY_SOURCE was not as easily fooled. This was causing the following complaint[1] from gcc v12: In file included from include/linux/string.h:253, from include/linux/ceph/ceph_debug.h:7, from fs/ceph/inode.c:2: In function 'fortify_memset_chk', inlined from 'netfs_i_context_init' at include/linux/netfs.h:326:2, inlined from 'ceph_alloc_inode' at fs/ceph/inode.c:463:2: include/linux/fortify-string.h:242:25: warning: call to '__write_overflow_field' declared with attribute warning: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Wattribute-warning] 242 | __write_overflow_field(p_size_field, size); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Fix this by embedding a struct inode into struct netfs_i_context (which should perhaps be renamed to struct netfs_inode). The struct inode vfs_inode fields are then removed from the 9p, afs, ceph and cifs inode structs and vfs_inode is then simply changed to "netfs.inode" in those filesystems. Further, rename netfs_i_context to netfs_inode, get rid of the netfs_inode() function that converted a netfs_i_context pointer to an inode pointer (that can now be done with &ctx->inode) and rename the netfs_i_context() function to netfs_inode() (which is now a wrapper around container_of()). Most of the changes were done with: perl -p -i -e 's/vfs_inode/netfs.inode/'g \ `git grep -l 'vfs_inode' -- fs/{9p,afs,ceph,cifs}/*.[ch]` Kees suggested doing it with a pair structure[2] and a special declarator to insert that into the network filesystem's inode wrapper[3], but I think it's cleaner to embed it - and then it doesn't matter if struct randomisation reorders things. Dave Chinner suggested using a filesystem-specific VFS_I() function in each filesystem to convert that filesystem's own inode wrapper struct into the VFS inode struct[4]. Version #2: - Fix a couple of missed name changes due to a disabled cifs option. - Rename nfs_i_context to nfs_inode - Use "netfs" instead of "nic" as the member name in per-fs inode wrapper structs. [ This also undoes commit 507160f46c55 ("netfs: gcc-12: temporarily disable '-Wattribute-warning' for now") that is no longer needed ] Fixes: bc899ee1c898 ("netfs: Add a netfs inode context") Reported-by: Jeff Layton <jlayton@kernel.org> Signed-off-by: David Howells <dhowells@redhat.com> Reviewed-by: Jeff Layton <jlayton@kernel.org> Reviewed-by: Kees Cook <keescook@chromium.org> Reviewed-by: Xiubo Li <xiubli@redhat.com> cc: Jonathan Corbet <corbet@lwn.net> cc: Eric Van Hensbergen <ericvh@gmail.com> cc: Latchesar Ionkov <lucho@ionkov.net> cc: Dominique Martinet <asmadeus@codewreck.org> cc: Christian Schoenebeck <linux_oss@crudebyte.com> cc: Marc Dionne <marc.dionne@auristor.com> cc: Ilya Dryomov <idryomov@gmail.com> cc: Steve French <smfrench@gmail.com> cc: William Kucharski <william.kucharski@oracle.com> cc: "Matthew Wilcox (Oracle)" <willy@infradead.org> cc: Dave Chinner <david@fromorbit.com> cc: linux-doc@vger.kernel.org cc: v9fs-developer@lists.sourceforge.net cc: linux-afs@lists.infradead.org cc: ceph-devel@vger.kernel.org cc: linux-cifs@vger.kernel.org cc: samba-technical@lists.samba.org cc: linux-fsdevel@vger.kernel.org cc: linux-hardening@vger.kernel.org Link: https://lore.kernel.org/r/d2ad3a3d7bdd794c6efb562d2f2b655fb67756b9.camel@kernel.org/ [1] Link: https://lore.kernel.org/r/20220517210230.864239-1-keescook@chromium.org/ [2] Link: https://lore.kernel.org/r/20220518202212.2322058-1-keescook@chromium.org/ [3] Link: https://lore.kernel.org/r/20220524101205.GI2306852@dread.disaster.area/ [4] Link: https://lore.kernel.org/r/165296786831.3591209.12111293034669289733.stgit@warthog.procyon.org.uk/ # v1 Link: https://lore.kernel.org/r/165305805651.4094995.7763502506786714216.stgit@warthog.procyon.org.uk # v2 Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2022-06-10scripts/check-local-export: avoid 'wait $!' for process substitutionMasahiro Yamada1-0/+12
Bash 4.4, released in 2016, supports 'wait $!' to check the exit status of a process substitution, but it seems too new. Some people using older bash versions (on CentOS 7, Ubuntu 16.04, etc.) reported an error like this: ./scripts/check-local-export: line 54: wait: pid 17328 is not a child of this shell I used the process substitution to avoid a pipeline, which executes each command in a subshell. If the while-loop is executed in the subshell context, variable changes within are lost after the subshell terminates. Fortunately, Bash 4.2, released in 2011, supports the 'lastpipe' option, which makes the last element of a pipeline run in the current shell process. Switch to the pipeline with 'lastpipe' solution, and also set 'pipefail' to catch errors from ${NM}. Add the bash requirement to Documentation/process/changes.rst.

2022-06-09ata: libata-transport: fix {dma|pio|xfer}_mode sysfs filesSergey Shtylyov1-5/+6
The {dma|pio}_mode sysfs files are incorrectly documented as having a list of the supported DMA/PIO transfer modes, while the corresponding fields of the *struct* ata_device hold the transfer mode IDs, not masks. To match these docs, the {dma|pio}_mode (and even xfer_mode!) sysfs files are handled by the ata_bitfield_name_match() macro which leads to reading such kind of nonsense from them: $ cat /sys/class/ata_device/dev3.0/pio_mode XFER_UDMA_7, XFER_UDMA_6, XFER_UDMA_5, XFER_UDMA_4, XFER_MW_DMA_4, XFER_PIO_6, XFER_PIO_5, XFER_PIO_4, XFER_PIO_3, XFER_PIO_2, XFER_PIO_1, XFER_PIO_0 Using the correct ata_bitfield_name_search() macro fixes that: $ cat /sys/class/ata_device/dev3.0/pio_mode XFER_PIO_4 While fixing the file documentation, somewhat reword the {dma|pio}_mode file doc and add a note about being mostly useful for PATA devices to the xfer_mode file doc...
