From 6300221b6c9b3127251c5909451de0bc62b4a01d Mon Sep 17 00:00:00 2001 From: Andrew Tridgell Date: Thu, 7 Dec 2006 04:02:20 +0000 Subject: r20059: james was asking about CAP_LARGE_READX and reads close to the 64k boundary. This test shows that both for Samba4 and w2k3, reads larger than or equal to 64k don't work (return zero bytes). Not that I claim this is very useful behaviour :-) (This used to be commit a10fa12ff5657a96e41b309558786780f294a75f) --- source4/torture/raw/read.c | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+) diff --git a/source4/torture/raw/read.c b/source4/torture/raw/read.c index da9580a472..483f1c6677 100644 --- a/source4/torture/raw/read.c +++ b/source4/torture/raw/read.c @@ -513,6 +513,26 @@ static BOOL test_readx(struct smbcli_state *cli, TALLOC_CTX *mem_ctx) CHECK_VALUE(io.readx.out.nread, io.readx.in.maxcnt); CHECK_BUFFER(buf, seed, io.readx.out.nread); + if (cli->transport->negotiate.capabilities & CAP_LARGE_READX) { + printf("Trying large readx\n"); + io.readx.in.offset = 0; + io.readx.in.mincnt = 0; + io.readx.in.maxcnt = 0x10000 - 1; + status = smb_raw_read(cli->tree, &io); + CHECK_STATUS(status, NT_STATUS_OK); + CHECK_VALUE(io.readx.out.nread, 0xFFFF); + + io.readx.in.maxcnt = 0x10000; + status = smb_raw_read(cli->tree, &io); + CHECK_STATUS(status, NT_STATUS_OK); + CHECK_VALUE(io.readx.out.nread, 0); + + io.readx.in.maxcnt = 0x10001; + status = smb_raw_read(cli->tree, &io); + CHECK_STATUS(status, NT_STATUS_OK); + CHECK_VALUE(io.readx.out.nread, 0); + } + printf("Trying locked region\n"); cli->session->pid++; if (NT_STATUS_IS_ERR(smbcli_lock(cli->tree, fnum, 103, 1, 0, WRITE_LOCK))) { -- cgit
