I noticed during integration testing that nbd-server blindly reports a size of 0 for all NBD_OPT_INFO requests, unless I pass a size argument on the command line to nbd-server. At first, I thought it was a side effect of me trying to use nbd-server on a block device (an LVM partition), as it is a common bug to rely on stat().st_size which only works for regular files (a block device has to use lseek(SEEK_END)); but then I noticed it happening when using nbd-server to serve regular files as well. I then turned to the source code, where I see that client->exportsize is set in just these places: commit_client() - exportsize = OFFT_MAX, then try setupexport() setupexport() - default to client->server->expected_size (if one was provided), further validating that actual size is large enough when actual size can be computed - if neither treefile or F_WAIT is set, compute actual size by opening one or more files and using size_autodetect() (which does the right thing for block devices, so my earlier thought about over-reliance on stat() was wrong) but these functions are only reached for NBD_OPT_EXPORT_NAME and NBD_OPT_GO, not NBD_OPT_INFO. The upshot is that for NBD_OPT_GO, there are some scenarios (treefile, F_WAIT) where nbd-server advertises a size of 9223372036854775807 (0x7fffffff_ffffffff) meaning unknown, but a size of 0 there is only possible if the file was successfully opened and really is zero bytes in length. Conversely, NBD_OPT_INFO is always advertising a size of 0, which means most of the time, the size changes between NBD_OPT_INFO and NBD_OPT_GO. For comparison, both nbdkit and qemu as an NBD server always advertise the same size for both NBD_OPT_INFO and NBD_OPT_GO (but it should also be noted that neither of these has the complexity of multifile like nbd-server). Should we tweak the NBD standard to recommend that a server advertise a size of OFFT_MAX for NBD_OPT_INFO if it is prohibitive to determine an actual size, rather than 0? Furthermore, is it worth adding code to make NBD_OPT_INFO try harder to provide a sensible value when possible (if expected_size was set, or if we are not multifile or F_WAIT, then a stat() is enough to get the size for serving a regular file; and if stat() says we have a block device, we can still try the open/lseek/close)? Also, is it worth trying to specify that since no known NBD servers allow exports with sizes larger than OFFT_MAX, a server MUST NOT report a size equal or larger than 9223372036854775808 (0x80000000_00000000)? There are definitely a few places that I could simplify in libnbd if we have a protocol guarantee that a valid export size will never have the most significant bit set, and therefore we don't have to worry about whether size is represented as a signed or unsigned value (which also implies that libnbd's function nbd_get_size() returning ssize_t instead of size_t is acceptable). But if we do that, then maybe 0x80000000_00000000 or even 0xffffffff_ffffffff would serve as a better recommended sentinel than 0x7fffffff_ffffffff for representing an indeterminate size. -- Eric Blake, Principal Software Engineer Red Hat, Inc.

[PATCH libguestfs] test-data/binaries: Remove +x attribute

by Richard W.M. Jones

These binaries are not meant to be run, they are purely data files used for testing. Remove the +x attribute to prevent accidentally running them. However to avoid breaking the phony guests, we need to chmod +x the files when we upload them into those guests. --- test-data/binaries/bin-aarch64-dynamic | Bin test-data/binaries/bin-armv7-dynamic |

[PATCH nbdkit v2 1/2] server: Reserve more characters from plugin/filter short names

by Richard W.M. Jones

The plugin/filter short name detection is very liberal, reserving only '.' and '/'. Thus, at least in theory, short plugin names containing almost arbitrary symbols and characters are permitted. Backslash ought to have been reserved when we added Windows support. We should probably reserve more characters, but in this commit I only reserve: * backslash (ie. directory separator on Windows) * ':' and ';' (common path separators) * '=' (used in nbdkit parameters) * space and comma (commonly used to separate lists) * non-printable ASCII characters Also DIR_SEPARATOR_STR, but that's likely to be already covered by the other tests so probably does nothing here. This commit is mainly about tightening up corner cases with possible security implications, for example if you managed to trick a program to invoke 'nbdkit "plugin param"' that might have an ambiguous parsing that you could use to your advantage. It should have no effect on normal, non-adversarial usage. --- server/options.h | 18 +++++++++++++++++- 1 file changed, 17 insertions(+), 1 deletion(-) diff --git a/server/options.h b/server/options.h index 7d0730bae7..8b1bd679e9 100644 --- a/server/options.h +++ b/server/options.h @@ -117,7 +117,23 @@ static const struct option long_options[] = { static inline bool is_short_name (const char *filename) { - return strchr (filename, '.') == NULL && strchr (filename, '/') == NULL; + const size_t n = strlen (filename); + size_t i; + + for (i = 0; i < n; ++i) { + switch (filename[i]) { + case '\0'...31: case 127: /* non-printable ASCII */ + case '/': case '\\': /* directory separators */ + case ':': case ';': /* path separators */ + case ' ': + case '.': + case ',': + case '=': + return false; + } + } + + return strstr (filename, DIR_SEPARATOR_STR) == NULL; } #endif /* NBDKIT_OPTIONS_H */ -- 2.44.0
