* Ensure I/O buffers in libufs(3) are 128-byte aligned.Kirk McKusick2023-11-171-32/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | Various disk controllers require their buffers to be aligned to a cache-line size (128 bytes). For buffers allocated in structures, ensure that they are 128-byte aligned. Use aligned_malloc to allocate memory to ensure that the returned memory is 128-byte aligned. While we are here, we replace the dynamically allocated inode buffer with a buffer allocated in the uufsd structure just as the superblock and cylinder group buffers do. This can be removed if/when the kernel is fixed. Because this problem has existed on one I/O subsystem or another since the 1990's, we are probably stuck with dealing with it forever. The problem most recent showed up in Azure, see: https://reviews.freebsd.org/D41728 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=267654 Before these fixes were applied, it was confirmed that the changes in this commit also fixed the issue in Azure.

* Remove #define _KERNEL hacks from libprocstatKonstantin Belousov2021-02-211-0/+2
| | | | | | | | | | | | | | | | | | Make sys/buf.h, sys/pipe.h, sys/fs/devfs/devfs*.h headers usable in userspace, assuming that the consumer has an idea what it is for. Unhide more material from sys/mount.h and sys/ufs/ufs/inode.h, sys/ufs/ufs/ufsmount.h for consumption of userspace tools, with the same caveat. Remove unacceptable hack from usr.sbin/makefs which relied on sys/buf.h being unusable in userspace, where it override struct buf with its own definition. Instead, provide struct m_buf and struct m_vnode and adapt code to use local variants.

* lib: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-261-1/+3
| | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using mis-identified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Notes: svn path=/head/; revision=326219

| | | | | | | | | | | | | | | | | | | | | | | for the sorts of errors we run into[1]. This also gives us room to put in a vaguely appropriate casts to silence warnings since our compiler doesn't like when we compare ssize_t to size_t[2]. Add a cast in sblock.c[3] to silence a warning because of signed vs. size_t hell (again). Clean up nearby excessive parenthemutilation[4]. Reviewed by: bde [2] [3] Suggested by: bde, many [1] Submitted by: bde [4] An aside about [4], bde notes that we do not check for a negative value for the fs bsize. I'm nto going to do that in every situation we use it, one must expect a reasonable program to pass down reasonable values. Some foot shooting protection I will tolerate, some I will not. Also he suggests some possible conditional improvements there, which I may take to heart. PS: For me at least, this is now WARNS=5 clean... Notes: svn path=/head/; revision=111111

the build. It is here to compartmentalise functionality currently duplicated in many notable programs in the base system. It currently handles block reads and writes, as well as reading and writing of the filesystem superblock, and the reading/lookup of inode data. It supports both UFS and UFS2. I will be maintaining it, and porting programs to use it, however for now, it is simply being built as part of world. Notes: svn path=/head/; revision=99193
