glusterfsd/src/glusterfsd.c: Move to GF_MALLOC() instead of GF_CALLOC() when possible

2018-09-07T03:40:47+00:00

It doesn't make sense to calloc (allocate and clear) memory
when the code right away fills that memory with data.
It may be optimized by the compiler, or have a microscopic
performance improvement.

In some cases, also changed allocation size to be sizeof some
struct or type instead of a pointer - easier to read.
In some cases, removed redundant strlen() calls by saving the result
into a variable.

1. Only done for the straightforward cases. There's room for improvement.
2. Please review carefully, especially for string allocation, with the
terminating NULL string.

Only compile-tested!

New flag to glusterfsd binary to print libexec dir

2018-09-05T06:44:59+00:00

New CLI option for `glusterfsd` binary to get the path of
libexec directory. This helps glusterd2 to detect the
installed path of `gsyncd` and other binaries.

Usage: `glusterfsd --print-libexecdir`

build: add --enable-asan configure options

2018-08-30T05:41:26+00:00

Introduce a `./configure --enable-asan` to build with
`-fsanitize=address -fno-omit-frame-pointer` options. This uses the
libasan.so shared library, so that needs to be available.

While running builds with the ASAN options, several linker issues
surfaced and these have been addressed with this change as well.
Building with --enable-asan has been tested on Fedora 28.

multiple files: move from strlen() to sizeof()

2018-08-29T06:09:10+00:00

{glusterfsd|glusterfsd-mgmt|quota-common-utils|xlator|tier|stripe}.c
tools/setgfid2path/src/main.c
xlators/cluster/afr/src/afr-inode-read.c
{glusterfs-acl|glusterfs}.h

For const strings, just do compile time size calc instead of runtime.

Compile-tested only!

coverity: Multiple coverity fixes for issues with HIGH severity

2018-08-22T18:13:12+00:00

glfs-fops.c
1391414 Uninitialized pointer read
List head needed initialization

glusterfsd-mgmt.c
graph.c
1382431 Buffer not null terminated
1382417 Dereference before null check
1382347 Buffer not null terminated
Cleaned usage of volfile_checksum member of gf_volfile_t struct
across the code base.

glusterd-tier.c
1382426 Resource leak
1370955 Dereference before null check
The function fixed needs more work, but with tier almost being
deprecated, addressed some parts of the reported coverity issues
as appropriate.

Tested using the following test cases:
./tests/basic/tier/new-tier-cmds.t
./tests/basic/tier/tier.t
./tests/basic/tier/bug-1214222-directories_missing_after_attach_tier.t
./tests/basic/tier/tier_lookup_heal.t
./tests/basic/tier/tier-heald.t
./tests/basic/tier/tier-snapshot.t
./tests/features/glfs-lease.t
