* fuse: add support for SEEK_HOLE and SEEK_DATA through lseek()Niels de Vos2016-02-101-1/+16
| | | | | | | | | | | | | | | | | | | | 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 23Ravishankar N2016-02-061-3/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | 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-wheelVenky Shankar2015-04-261-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Avoid conflict between contrib/uuid and system uuidEmmanuel Dreyfus2015-04-0411-59/+59
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | glusterfs relies on Linux uuid implementation, which API is incompatible with most other systems's uuid. As a result, libglusterfs has to embed contrib/uuid, which is the Linux implementation, on non Linux systems. This implementation is incompatible with systtem's built in, but the symbols have the same names. Usually this is not a problem because when we link with -lglusterfs, libc's symbols are trumped. However there is a problem when a program not linked with -lglusterfs will dlopen() glusterfs component. In such a case, libc's uuid implementation is already loaded in the calling program, and it will be used instead of libglusterfs's implementation, causing crashes. A possible workaround is to use pre-load libglusterfs in the calling program (using LD_PRELOAD on NetBSD for instance), but such a mechanism is not portable, nor is it flexible. A much better approach is to rename libglusterfs's uuid_* functions to gf_uuid_* to avoid any possible conflict. This is what this change attempts.

* contrib/timer-wheel: import linux kernel timer-wheelVenky Shankar2015-03-183-0/+417
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch imports timer-wheel[1] algorithm from the linux kernel (~/kernel/time/timer.c) with some modifications. Timer-wheel is an efficent way to track millions of timers for expiry. This is a variant of the simple but RAM heavy approach of having a list (timer bucket) for every future second. Timer-wheel categorizes every future second into a logarithmic array of arrays. This is done by splitting the 32 bit "timeout" value into fixed "sliced" bits, thereby each category has a fixed size array to which buckets are assigned. A classic split would be 8+6+6+6 (used in this patch) which results in 256+64+64+64 == 512 buckets. Therefore, the entire 32 bit futuristic timeouts have been mapped into 512 buckets. [ NOTE: There are other possible splits, such as "8+8+8+8", but this patch sticks to the widely used and tested default. ] Therfore, the first category "holds" timers whose expiry range is between 1..256, the next cateogry holds 257..16384, third category 16385..1048576 and so on. When timers are added, unless it's in the first category, timers with different timeouts could end up in the same bucket. This means that the timers are "partially sorted" -- sorted in their highest bits. The expiry code walks the first array of buckets and exprires any pending timers (1..256). Next, at time value 257, timers in the first bucket of the second array is "cascaded" onto the first category and timers are placed into respective buckets according to the thier timeout values. Cascading "brings down" the timers timeout to the coorect bucket of their respective category. Therefore, timers are sorted by their highest bits of the timeout value and then by the lower bits too.

* logging: remove unused message-id scriptsNiels de Vos2014-05-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | The current unused implementation for message-ids in the logs depends on automatically generated files. The generated files are not included in the distributed tarball. This causes issues when distributions build packages, they need to re-run ./autogen.sh to create the needed files. I thought of including the generated files in the distribution tarball. However, the contents of these files are not actively used, so it seems to make more sense to drop it all together. These functions were the only users of libintl and gettext too, so dropped the requirement checking from configure.ac. A replacement for the message-id logging framework is in progress. Any changes that this patch makes, can be reverted in the submission of patches for the new framework.

* features/qemu-block: simplify coroutine model to use single synctask, ucontextBrian Foster2013-11-102-1/+225
| | | | | | | | | | | | | | | | | | | | | | | | The current coroutine model, mapping synctasks 1-1 with qemu internal Coroutines, has some unresolved raciness issues. This problem usually manifests as lifecycle mismatches between top-level (gluster created) synctasks and the subsequently created internal coroutines from that context. Qemu's internal queueing (and locking) can cause situations where the top-level synctask is destroyed before the internal scheduler has released references to memory, leading to use after free crashes and asserts. Simplify the coroutine model to use a single synctask as a coroutine processor and rely on the existing native ucontext coroutine implementation. The syncenv thread is donated to qemu and ensures a single top-level coroutine is processed at a time. Qemu now has complete control over coroutine scheduling.

Gluster sets this flag, so set FUSE_FLOCK_LOCKS as well on kernels that support version 17 or newer. 7.18 - Adds ioctl() support for directories (and the associated FUSE_IOCTL_DIR flag). Gluster does not support the ioctl request, so no changes are required. Update the header. - Adds support for the delete notification to allow a filesystem to inform the kernel of a deleted inode. No gluster changes required. 7.19 - Adds support for the fallocate request. Gluster already supports fallocate and includes the request opcode definition and data structure. Update the header version number. 7.20 - Adds the FUSE_AUTO_INVAL_DATA init flag to enable attribute updates on reads and automatic cache invalidation on mtime changes. Behavior does not change unless the init flag is specified, no gluster changes required. Update header. 7.21 - Adds readdirplus support and updates the poll request to include events. Gluster already supports readdirplus and includes the relevant data structures. Poll is not supported, so no changes are required. Update the header with some missing READDIRPLUS_AUTO bits. 7.22 - Adds real asynchronous direct I/O support.
