From 9b725c15cf50cfb85ec6ec88c47843092775dedc Mon Sep 17 00:00:00 2001 From: Jakob Unterwurzacher Date: Sun, 3 Jul 2016 19:14:12 +0200 Subject: syscallcompat: OSX: add Fallocate and Openat wrappers ...and convert all calls to syscall.{Fallocate,Openat} to syscallcompat . Both syscalls are not available on OSX. We emulate Openat and just return EOPNOTSUPP for Fallocate. --- internal/fusefrontend/file_allocate_truncate.go | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'internal/fusefrontend/file_allocate_truncate.go') diff --git a/internal/fusefrontend/file_allocate_truncate.go b/internal/fusefrontend/file_allocate_truncate.go index 65d6df6..f22fa4b 100644 --- a/internal/fusefrontend/file_allocate_truncate.go +++ b/internal/fusefrontend/file_allocate_truncate.go @@ -10,6 +10,7 @@ import ( "github.com/hanwen/go-fuse/fuse" + "github.com/rfjakob/gocryptfs/internal/syscallcompat" "github.com/rfjakob/gocryptfs/internal/tlog" ) @@ -59,7 +60,7 @@ func (f *file) Allocate(off uint64, sz uint64, mode uint32) fuse.Status { cipherOff := firstBlock.BlockCipherOff() cipherSz := lastBlock.BlockCipherOff() - cipherOff + f.contentEnc.PlainSizeToCipherSize(lastBlock.Skip+lastBlock.Length) - err := syscall.Fallocate(f.intFd(), FALLOC_FL_KEEP_SIZE, int64(cipherOff), int64(cipherSz)) + err := syscallcompat.Fallocate(f.intFd(), FALLOC_FL_KEEP_SIZE, int64(cipherOff), int64(cipherSz)) tlog.Debug.Printf("Allocate off=%d sz=%d mode=%x cipherOff=%d cipherSz=%d\n", off, sz, mode, cipherOff, cipherSz) if err != nil { -- cgit v1.2.3
