qemu-block: deprecated/defunct, remove from tree

2016-03-07T11:34:59+00:00

qemu-block xlator is not used by anyone, or so I'm told.

It's also substantially out of date. There's little reason to keep
it in our sources. (And FedoraProject doesn't like bundled software
either.)

fuse: add support for SEEK_HOLE and SEEK_DATA through lseek()

2016-02-11T06:16:50+00:00

The Linux FUSE kernel module has gained support for passing SEEK_HOLE
and SEEK_DATA on through lseek(). This can greatly improve performance
when working with sparse files.

Linux FUSE introduced support for lseek() with version 4.5. The commit
in mainline Linux is 0b5da8db145bfd44266ac964a2636a0cf8d7c286.

fuse: update fuse_kernel.h to version 23

2016-02-07T05:56:46+00:00

The following changes were made upstream:
 - add FUSE_WRITEBACK_CACHE
 - add time_gran to fuse_init_out
 - add reserved space to fuse_init_out
 - add FATTR_CTIME
 - add ctime and ctimensec to fuse_setattr_in
 - add FUSE_RENAME2 request
 - add FUSE_NO_OPEN_SUPPORT flag

Including these changes will make it easier to backport support for
lseek().

Because the fuse_init_out structure changed its size, older versions of
FUSE would fail initializing. When an older version of FUSE is detected,
the fuse_init_out structure is reduced to the previous size. This is
harmless, as the attributes that are not passed, are not used for
earlier versions anyway.

build: fix ecdh.h and dh.h deps

2015-11-16T15:40:43+00:00

openssl.ecdh.h and openssl/dh.h are not available on all platforms.
This patch adds check to autoconf and updates relevant source files.
Add missing #include "config.h" to socket.c to make HAVE_OPENSSL_DH_H
and HAVE_OPENSSL_ECDH_H macros available.

Definitions for UTIME_OMIT and UTIME_NOW in
contrib/qemu/util/oslib-posix.c have been selected from
/usr/include/bits/stat.h on Fedora 22

SSL context options SSL_OP_NO_TICKET and SSL_OP_NO_COMPRESSION are now
conditionally set by testing their presence.

glusterfs.spec.in file now adds CFLAGS=-DUSE_INSECURE_OPENSSL for
RHEL < 6 in the %build section.

features/bitrot: cleanup, v2

2015-06-25T11:45:19+00:00

This patch uses "cleanup, v1" infrastrcuture to cleanup scrubber
(data structures, threads, timers, etc..) on brick disconnection.
Signer is not cleaned up yet: probably would be done as part of
another patch.

contrib/timer-wheel: fix deadlock in del_timer()

2015-06-03T03:24:27+00:00

commit eaf3bfa added mod_timers() and successfully screwed up
del_timer() by incorrectly wrapping it within double lock
blocks.

del_timer() was included before the above commit for the sake of
timer API completion, thankfully noone used it till now.

contrib/timer-wheel: mod_timer() and friends

2015-05-28T09:44:25+00:00

Couple of timer-wheel api's to modify timer expiry times:

  mod_timer()
  mod_timer_pending()

Both the api's perform almost the same job with one minute
difference: mod_timer_pending() modifies timer expiry only
if the timer is pending (i.e. being tracked in timer-wheel).

fuse: fix return value check for setuid

2015-05-16T07:19:09+00:00

setuid() sets the effective user ID of the calling process. If the
effective UID of the caller is root, the real UID and saved set-user-ID
are also set. On success, zero is returned.  On error, -1 is returned,
and errno is set appropriately.

there are cases where setuid() can fail even when the caller is UID 0;
it is a grave security error to omit checking for a failure return from
setuid(). if an environment limits the number of processes a user can
have, setuid() might fail if the target uid already is at the limit.

Fix is to check return value of setuid.

core: Global timer-wheel

2015-04-26T18:04:11+00:00

Instantiate a process wide global instance of the timer wheel
data structure. Spawning glusterfs* process with option arg
"--global-timer-wheel" instantiates a global instance of
timer-wheel under global context (->ctx).

Translators can make use of this process wide instance [via a
call to glusterfs_global_timer_wheel()] instead of maintaining
an instance of their own and possibly consuming more memory.
Linux kernel too has a single instance of timer wheel where
subsystems such as IO, networking, etc.. make use of.

Bitrot daemon would be early consumers of this: bitrot translator
instances for multiple volumes would track objects belonging to
their respective bricks in this global expiry tracking data
structure. This is also a first step to move GlusterFS timer
mechanism to use timer-wheel.
