* tarfs: Fix support for large filesDag-Erling Smørgrav2025-11-121-1/+1
| | | | | | | | | | | | | | | | | | | | * When fast-forwarding through a zstd frame, we incorrectly used the min() inline function instead of the MIN() macro. The function truncates the result to unsigned int, resulting in a decompression error when trying to seek more than 4 GB into the frame. * POSIX states that a size extended header record overrides the size field in the header if present, and that one must be included if the size of the file exceeds 8 GB (the size field maxes out at 64 GB). * Reduce repetition in the exthdr parser by deduplicating the syntax error handler.

| | | | | | | | | | | | | | | | | | * tarfs_alloc_mount(): Remove an unnecessary null check (CID 1504505) and an unused variable. * tarfs_alloc_one(): Verify that the file size is not negative (CID 1504506). While there, also validate the mode, owner and group. * tarfs_vget(), tarfs_zio_init(): Explicitly ignore return value from getnewvnode(), which cannot fail (CID 1504508) * tarfs_lookup_path(): Fix a case where a specially-crafted tarball could trigger a null pointer dereference by first descending into, and then backing out of, a previously unknown directory. (CID 1504515) * mktar: Construct a tarball that triggers the aforementioned null pointer dereference. Reported by: Coverity Sponsored by: Juniper Networks, Inc. Sponsored by: Klara, Inc.

| | | | | | | | | Some of the code in sys/fs/tarfs/tarfs_io.c is not specific to zstd, but is still only used when some form of decompression is enabled. Put it behind #ifdef TARFS_ZIO to silence warnings. Sponsored by: Juniper Networks, Inc. Sponsored by: Klara, Inc. Reviewed by: kib Differential Revision: https://reviews.freebsd.org/D38415
