Hi,
I am using libzbc in emulation mode (i.e. with a conventional device).
After writing to a zone via zbc_write_zone, reading from the zone using zbc_read_zone fails.
I think the reason for this is because of zbc_fake.c line 271:
if (zone->zbz_write_pointer + lba_count >
zone->zbz_start + zone->zbz_length)
return -EIO;
I believe this snippet is copied over from zbc_file_pwrite.
I think for zbc_file_pread, it should be modified to:
if (start_lba + lba_count >
zone->zbz_start + zone->zbz_length)
return -EIO;
Thanks!

Hi,
I am trying to write an entire zone (256 MB) on an actual drive (not a fake one) and I am getting a "Cannot Allocate Memory (-12)" error. I am using the "zbc_write_zone" program.
The same does not happen if I write only 4 MB, and the interesting thing is that the program ends up writing 4 MB, 64 times. Hence, the total amount written is 256 MB. Yet, it gives an error if I write all 256 MB at once. Is this a bug or is this expected behavior?
Also, I get the same error "Cannot Allocate Memory (-12)" if I ever write more than 4 MB. Please find attached, the output from my terminal.
Note: This does not happen on a fake drive with emulation. I am able to write an entire zone without issue.
Thanks,
Yash

I'm trying to build libzbc v5.8.5 on an Oracle Linux VM - 4.14.35-1902.3.2.el7uek.x86_64. The configure step fails with this error:
./configure --with-test CFLAGS=-fPIC

I've had no luck building this on physical machine with the same OS installed as well. I get the same error. Any ideas, what's going on?
Is there a way to compile without libgtk? I am hitting this issue referenced earlier: #2 but I don't want to build the GUI program and it seems it should be optional based on how the autoconf file is authored.

Any help/tips appreciated!
Would you like to add more error handling for return values from functions like the following?
I would like to point out that identifiers like “_LIBZBC_H_” and “__GZBC_H__” do not fit to the expected naming convention of the C language standard.
Would you like to adjust your selection for unique names?
I was going to add support for vector I/O with new zbc_preadv and zbc_pwritev interfaces with your approval.
One question I have before getting started is if vector I/O is supported by Direct I/O when using the sg driver.
In here: https://www.tldp.org/HOWTO/pdf/SCSI-Generic-HOWTO.pdf
I see
Furthermore iovec_count's variety of scatter gather (into the user space) is only available when normal (or "indirect") IO is being used. Hence when the SG_FLAG_DIRECT_IO or SG_FLAG_MMAP_IO are set in 'flags' then 'iovec_count' should be zero.
However, inspecting the 4.20 kernel, I don't see any limitation so perhaps this statement is obsolete. Are you aware?
As an experiment I added a single sg_iovec_t iovec[1]; to zbc_sg_cmd and funneled all I/O through this single vector in zbc_sg_cmd_init. I think this is a decent hack
if (cmd->out_bufsz) {
cmd->io_hdr.dxferp = cmd->iovec;
cmd->io_hdr.iovec_count = 1;
cmd->iovec[0].iov_base = cmd->out_buf;
cmd->iovec[0].iov_len = cmd->out_bufsz;
}
I'm not seeing any errors with reads or writes. Do you think this is enough to prove this out?
Hi, I am trying to use libzbc library to test the Seagate Host Aware 8TB HDD Drive.
$ sudo zbc_info /dev/sg1
Device /dev/sg1: ATA ST8000AS0022-1WL SN01
ATA ZAC interface, Host-aware disk model
15628053168 logical blocks of 512 B
1953506646 physical blocks of 4096 B
8001.563 GB capacity
All tests pass except the two Sense Key Tests for reporting zones as shown below:
Executing sense key, sense code tests...
010: REPORT_ZONES logical block out of range... [Failed]
=> Expected Illegal-request / Logical-block-address-out-of-range
Got /
011: REPORT_ZONES invalid reporting option... [Failed]
=> Expected Illegal-request / Invalid-field-in-cdb
Got Illegal-request / Unaligned-write-command
Running the tests individually gives us the following output:
sudo ./zbc_test_report_zones -v -lba 15628053168 /dev/sg1

Hi,
I am trying compile-and-install libzbc-master following README,but when runing zbc_test.sh in libzbc-master there are errors :Test program zbc_test_close_zone not found in directory /home/zhaoyajun/Documents/libzbc-master/test/programs .
Whether or not /test/programs/close_zone/Makemodule.am do not run ,I need your help.
Thanks .
David
This is more of a question than a problem/issue..
Background:
I am interested in writing Rust bindings for libzbc. I see the header and library source files of libzbc have both BSD-2-Clause and LGPL-3.0-or-later licenses present. If/when I finish this poject, I'd like to release it under the same licenses as libzbc.
Question:
Are consumers of libzbc free to choose from either license, or will they need to comply with both?
Said another way: Will anybody linking statically to libzbc also need to release their application's source code in order to comply with LGPL obligations (since there is no static linking exception)?
I can organize the Rust project to link against libzbc either way (statically, or dynamically). I'll probably add a feature flag so linking either way remains possible. I'm just trying to decide which method of linking should be the default.
Thanks in advance for any guidance / much appreciated
In using a custom symbolic link for the device path, the zbc_sg_max_segments code will fail to read the max segments as it is assuming the absolute device path.
Add code to check if the zbd_filename is a link and decode the link. Something like:
/**
* Gets the absolute device path from the input device
*/
static void zbc_sg_device_path(struct zbc_device *dev, char *path, int path_len)
{
struct stat lst;
ssize_t len;
strncpy(path, dev->zbd_filename, path_len);
if (lstat(dev->zbd_filename, &lst) == 0) {
if (S_ISLNK(lst.st_mode)) {
len = readlink(dev->zbd_filename, path, path_len-1);
if (len < 0) {
zbc_error("%s: readlink failed %d (%s)\n",
dev->zbd_filename,
errno, strerror(errno));
} else {
path[len] = '\0';
}
}
}
}
Hi. I'm trying to build on Ubuntu 12.10 (yes, it's back-level) and am running into a problem I don't know how to solve. Would you please help me out?
When I run ./configure, I get the following response:
...
checking for GTK... no
configure: error: Package requirements (gtk+-2.0) were not met:
No package 'gtk+-2.0' found
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables GTK_CFLAGS
and GTK_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
So, I cleverly tried installing gtk+-2.0 by issuing "sudo apt-get install gtk+-2.0". This gets me the following response:
...
Note, selecting 'gir1.0-gtk-2.0' for regex 'gtk+-2.0'
gir1.2-gtk-2.0 is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 6 not upgraded.
Can you suggest what I need to do? Thanks,
Steve
I'm doing host restart testing where we power down the host after I/O is written and then verify the host data on power on. Nothing should be in-flight when the power down occurs.
Prior power loss I see sectors being written
(libzbc) /data/fake/fakesmr3: Write 784 sectors at sector 218352
However after a power cycle the zone is empty, resulting in I/O errors
(libzbc) /data/fake/fakesmr3: Read 784 sectors at sector 218352 (libzbc) [ERROR] /data/fake/fakesmr3: Read 784 sectors at sector 218352 failed 5 (Input/output error)
Using zbc_report_zones I can easily see there are zones we have written to but remain empty following power-cycle, including our zone with the target read
Zone 00100: type 0x2 (Sequential-write-required), cond 0xe (Full), reset recommended 0, non_seq 0, sector 204800, 2048 sectors, wp 206848 Zone 00101: type 0x2 (Sequential-write-required), cond 0xe (Full), reset recommended 0, non_seq 0, sector 206848, 2048 sectors, wp 208896 Zone 00102: type 0x2 (Sequential-write-required), cond 0xe (Full), reset recommended 0, non_seq 0, sector 208896, 2048 sectors, wp 210944 Zone 00103: type 0x2 (Sequential-write-required), cond 0xe (Full), reset recommended 0, non_seq 0, sector 210944, 2048 sectors, wp 212992 Zone 00104: type 0x2 (Sequential-write-required), cond 0xe (Full), reset recommended 0, non_seq 0, sector 212992, 2048 sectors, wp 215040 Zone 00105: type 0x2 (Sequential-write-required), cond 0x1 (Empty), reset recommended 0, non_seq 0, sector 215040, 2048 sectors, wp 215040 Zone 00106: type 0x2 (Sequential-write-required), cond 0x1 (Empty), reset recommended 0, non_seq 0, sector 217088, 2048 sectors, wp 217088 Zone 00107: type 0x2 (Sequential-write-required), cond 0x1 (Empty), reset recommended 0, non_seq 0, sector 219136, 2048 sectors, wp 219136 Zone 00108: type 0x2 (Sequential-write-required), cond 0x1 (Empty), reset recommended 0, non_seq 0, sector 221184, 2048 sectors, wp 221184
The question I have is does the fake driver support power-loss testing? It's almost like the metadata isn't synchronized with the process and data is loss. Does this seem like a sound understanding of the problem?
I ran the commands in the order posted. Most of tests hadn't succeed, such as zbc_set_zones.
I have attached a terminal log script. Please have a look
test.txt
Thanks
Sincerely
David
I suggest that, instead of putting the set zones emulation metadata into /tmp, that it be placed in /etc/zbc/.meta. This would allow persistence across boots.
Thanks
Hi,
I noticed that zbc_ata.c retrieves zone information by reading log 0x1A (in the zbc_ata_report_zones function). Are there plans to support the proposed REPORT ZONES command?
A draft of this command is given here:
http://www.t13.org/Documents/UploadedDocuments/docs2014/f14162r3-ZAC-_Report_Zones_command.pdf
-Austin
Currently the zbc_errno struct is defined per device and is cleared / reset per I/O. When using async I/O to the same device, one runs the risk of losing critical sense key / sense code information.
I'm wondering if we can make zbc_errno thread local.
Alternatively, we could open multiple zbd device handles per I/O thread.
I can build v4.3.0 but v4.3.1 fails with
lib/zbc_block.c:29:28: fatal error: linux/blkzoned.h: No such file or directory
The build machine is on kernel 4.4.0-42-generic and I've got the kernel headers installed.
When I was using v4.0 on an emulated SATA drive, all the tests run. However, zbc_report_zones listed 0 zones. gzbc showed no zones.
Switching to v2.0 and everything seems to work.
Can anybody reproduce this problem?

I think there should be an easy way to choose the device types we want to try in zbc_open. If you guys are ok with adding another parameter to zbc_open (say a bitmask enabling/disabling) device types, I can work on a diff for that.
