8 years agostats: fix io_u_plat out-of-bound accesses (round 2)
Eric Gouriou [Tue, 16 Aug 2011 06:35:43 +0000 (08:35 +0200)]
stats: fix io_u_plat out-of-bound accesses (round 2)

Commit 833491908a1afd67 introduced the ability to report completion
latency percentiles. It also caused a memory corruption when running
with multiple threads due to out of bound accesses in show_run_stats().
The major index of the io_u_plat two-dimensional array is meant
to be DDIR_ value in {DDIR_READ, DDIR_WRITE} (i.e., {0, 1}). The
code in show_run_stats() incorrectly wrote into the array using
a major index with values {0, 1, 2}. Commit 0a0b49007cbce8d1 fixed
the out of bound accesses by increasing the size of the major
dimension of the io_u_plat array from 2 to 3.

This patch reverts the size change from 0a0b49007cbce8d1 in favor
of avoiding the out-of-bound accesses in show_run_stats().

8 years agoFix bug in smalloc size calculation
Jiri Horky [Mon, 15 Aug 2011 13:18:03 +0000 (15:18 +0200)]
Fix bug in smalloc size calculation

Jiri reports:

I think I found a bug. If the device (file) used in fio has "wrong" size, and is used with "wrong" block size, the fio fails to allocate memory for randommap.
Following conditions must be true, considering just one thread for simplicity:

 1) number of blocks on the device are too big to fill in the default's pool
 2) number of blocks on the device must be "right", so the size of newly allocated pool by smalloc.c:add_pool is exactly as big as requested size (there are some roundings in place, so not every size triggers this error)

When this is true, function smalloc.c:__smalloc_pool fails to use the newly created (exactly big enough) pool, because of this line:

                idx = find_next_zero(pool->bitmap[i], last_idx);

which always returns non-zero value (the minimum returned value is last_idx +1), and so in our case the idx is 1 even though, the block number 0 is free. As the direct consequence, the function doesn't find enough free space in the given pool and returns NULL pointer. This leads to another try to allocate enough memory in smalloc.c:smalloc_real function, and so on...

The behavior could be reprocuded using both stable 1.57 and git version of the tool. The values that triggers the error are:
init_random_map - real_file_size: 21999995584512, o.rw_min_bs: 4096, blocks: 5371092672, num_maps: 83923323, alloc size: 671386584

whereas this block device is fine:
init_random_map - real_file_size: 19999995985920, o.rw_min_bs: 4096, blocks: 4882811520, num_maps: 76293930, alloc size: 610351440

the configuration file used:

[global]
description=CESNET_test
[cesnet]
filename=/dev/sdd
rw=randread
size=10000g
ioengine=libaio
iodepth=4
bs=4k
runtime=10m
time_based
numjobs=1
group_reporting

Get rid of the +1, it looks like a remnant from when the pools
had a header associated with them.

Allow percentage setting for size=

Sometimes it's useful to set this to a particular size of a device.
Allowing percentages makes this more easy, as one does not have to
do the math outside of fio and pass in as environment variables
or custom job files.

To use, simply add a

size=15%

or whatever is needed, then fio will use 15% of the total size of
the device(s) or file(s) given. Percentage can be from 1 to 100.

Add ability to invoke fallocate() FALLOC_FL_KEEP_SIZE.

Linux offers fallocate() and the FALLOC_FL_KEEP_SIZE option as
an alternative to posix_fallocate(). When FALLOC_FL_KEEP_SIZE is
specified for an falloc request going beyond the end of the file,
the requested blocks get preallocated without changing the apparent
size of the file. This is is a commonly recommended use of fallocate()
for workloads performing append writes.

This patch modifies the fallocate option from a boolean option
to a string option accepting none/posix/keep/0/1. 'keep' is only
made available on systems where FALLOC_FL_KEEP_SIZE is available
(i.e., Linux at this time). If specified, fallocate() is used
with FALLOC_FL_KEEP_SIZE set. 'none' disables pre-allocation while
'posix' uses posix_fallocate(). The default behavior remains unchaned,
i.e., invoking posix_fallocate. The settings '0'/'1' are there to
provide backward compatibility for users who had explicitly set the
boolean option.

tmpfs (e.g. splice-cp).

This happens with current fio-master or fio-1.38-1 (debian package)
thanks for any comments,

The reason is that splice uses ->o.odirect to set that we want aligned
buffers, but we actually have a flag for that now. So just use that.
