* makefs (msdosfs): Use fprintf instead of debug print for errorsAlex Richardson2020-08-241-3/+3
| | | | | | | | | | The added print was very helpful for debugging failed disk image creation. Reviewed By: emaste Differential Revision: https://reviews.freebsd.org/D23200 Notes: svn path=/head/; revision=364648
* makefs: Drop unnecessary sys/clock.h includeAlex Richardson2020-08-071-1/+0
| | | | | | | | | This breaks the build on macOS where this header doesn't exist. I could also add a compat header to tools/build/cross-build but since it's not needed removing it seems like the better solution. Notes: svn path=/head/; revision=364024

* Allow bootstrapping makefs on older FreeBSD hosts and Linux/macOSAlex Richardson2020-01-272-4/+4
| | | | | | | | | | | | | | | | | | | | | | In order to do so we need to install the msdosfs headers to the bootstrap sysroot and avoid includes of kernel headers that may not exist on every host (e.g. sys/lockmgr.h). This change should allow bootstrapping of makefs on FreeBSD 11+ as well as Linux and macOS. We also have to avoid using the IO_SYNC macro since that may not be available. In makefs it is only used to switch between calling bwrite() and bdwrite() which both call the same function. Therefore we can simply always call bwrite(). For our CheriBSD builds we always bootstrap makefs by setting LOCAL_XTOOL_DIRS='lib/libnetbsd usr.sbin/makefs' and use the makefs binary from the build tree to create a bootable disk image.

* buf: Add B_INVALONERR flag to discard dataConrad Meyer2019-09-115-0/+5
| | | | | | | | | | | | | | | | | | | | | | Setting the B_INVALONERR flag before a synchronous write causes the buf cache to forcibly invalidate contents if the write fails (BIO_ERROR). This is intended to be used to allow layers above the buffer cache to make more informed decisions about when discarding dirty buffers without successful write is acceptable. As a proof of concept, use in msdosfs to handle failures to mark the on-disk 'dirty' bit during rw mount or ro->rw update. Extending this to other filesystems is left as future work.

* makefs: add msdosfs (FAT) supportEd Maste2019-08-2011-286/+2784
| | | | | | | | | | | | | | | | | | | | | | Add FAT support to makefs by copying some files from sys/fs/msdosfs/ and updating others with changes from NetBSD. The six files copied from sys/fs/msdosfs at r348251 and modified are: denode.h direntry.h fat.h msdosfs_fat.c msdosfs_lookup.c msdosfsmount.h I would prefer to avoid the duplication, but reluctance to doing so was expressed in a previous review (D11197); for now copy the files and revisit in the future.
