* Multiple xlator .h files: remove unused private gf_* memory types.Yaniv Kaul2018-11-301-1/+0
| | | | | | | | | | | | | It seems there were quite a few unused enums (that in turn cause unndeeded memory allocation) in some xlators. I've removed them, hopefully not causing any damage.

* features/locks: Move logging outside of a locked regionVijay Bellur2018-11-191-3/+3
| | | | | | | | | | | | In pl_metalk(), logging was being done in a synchronized region. Moving the log out of the synchronized region to avoid other threads from being blocked on the lock. Thanks to Yaniv Kaul for pointing this out. Change-Id: I0cb39fb23ae7c798ca9c42c390500491aa8e622b updates: bz#1644758 Signed-off-by: Vijay Bellur <vbellur@redhat.com>

* lock: Do not allow meta-lock count to be more than oneSusant Palai2018-11-061-1/+34
| | | | | | | | | | | | | | | | | | | | In the current scheme of glusterfs where lock migration is experimental, (ideally) the rebalance process which is migrating the file should request for a metalock. Hence, the metalock count should not be more than one for an inode. In future, if there is a need for meta-lock from other clients, this patch can be reverted. Since pl_metalk is called as part of setxattr operation, any client process(non-rebalance) residing outside trusted network can exhaust memory of the server node by issuing setxattr repetitively on the metalock key. The current patch makes sure that more than one metalock cannot be granted on an inode.

* all: fix the format string exceptionsAmar Tumballi2018-11-051-5/+5
| | | | | | | | | | | | | | | | Currently, there are possibilities in few places, where a user-controlled (like filename, program parameter etc) string can be passed as 'fmt' for printf(), which can lead to segfault, if the user's string contains '%s', '%d' in it. While fixing it, makes sense to make the explicit check for such issues across the codebase, by making the format call properly.

| | | | | | | | | | | | | | | | | | | | strncpy may not be very efficient for short strings copied into a large buffer: If the length of src is less than n, strncpy() writes additional null bytes to dest to ensure that a total of n bytes are written. Instead, use snprintf(). Check for truncated output where applicable. Also: - save the result of strlen() and re-use it when possible. - move from strlen to SLEN (sizeof() ) for const strings.

* build: add --without-server optionNiels de Vos2018-02-191-0/+4
| | | | | | | | | | | | | | | | With Gluster 4.0 we will not provide the server components for EL6 and older. At one point Gluster 4.x will get GlusterD2, which requires Golang tools in the distribution. EL6 does not contain these at the moment. With this change, it is possible to `./configure --without-server` which prevents building glusterd and the xlators for the bricks. Building RPMs can pass `--without server` and the glusterfs-server sub-package will not be created.

| | | | | | | | | | | | | | | | The current API for byte-range locks [glfs_posix_lock()] doesn't allow applications to specify whether it is advisory or mandatory type locks. This particular change is to introduce an extended byte-range lock API with an additional argument for including the byte-range lock mode to be one among advisory(default) or mandatory. Patch also includes a gfapi test case which make use of this new api to acquire mandatory locks.

* features/locks: Maintain separation of lock->client_pid, flock->l_pidPranith Kumar K2017-09-272-34/+15
| | | | | | | | | | | | | | | | | | Problem: grant_blocked_locks() constructs flock from lock. Locks xlator uses frame->root->pid interchangeably flock->l_pid. With gNFS frame->root->pid (which translates to lock->client_pid) is not same as flock->l_pid, this leads to lk's cbk returning flock with l_pid from lock->client_pid instead of input flock->l_pid. This triggers EC's error code path leading to failure of lk call, because the response' flock->l_pid is different from request's flock->l_pid. Fix: Maintain separation of lock->client_pid, flock->l_pid. Always unwind with flock with correct pid.

By converging on a single pattern, navigating from xyz_t in code to the actual definition of struct _xyz (i.e. without having to visit the typedef first) might even be automatable.

* core: run many bricks within one glusterfsd processJeff Darcy2017-01-301-5/+5
| | | | | | | | | | | | | | | | | | | | | | | This patch adds support for multiple brick translator stacks running in a single brick server process. This reduces our per-brick memory usage by approximately 3x, and our appetite for TCP ports even more. It also creates potential to avoid process/thread thrashing, and to improve QoS by scheduling more carefully across the bricks, but realizing that potential will require further work. Multiplexing is controlled by the "cluster.brick-multiplex" global option. By default it's off, and bricks are started in separate processes as before. If multiplexing is enabled, then *compatible* bricks (mostly those with the same transport options) will be started in the same process.

Rewrite the make rules to do what xdrgen does. Now we can get rid of xdrgen. Note 1. netbsd6's sed doesn't do -i. Why are we still running smoke tests on netbsd6 and not netbsd7? We barely support netbsd7 as it is. Note 2. Why is/was libgfxdr.so (.../rpc/xdr/src/...) linked with libglusterfs? A cut-and-paste mistake? It has no references to symbols in libglusterfs. Note3. "/#ifndef\|#define\|#endif/" (note the '\'s) is a _basic_ regex that matches the same lines as the _extended_ regex "/#(ifndef|define|endif)/". To match the extended regex sed needs to be run with -r on Linux; with -E on *BSD. However NetBSD's and FreeBSD's sed helpfully also provide -r for compatibility. Using a basic regex avoids having to use a kludge in order to run sed with the correct option on OS X. Note 4. Not copying the bit of xdrgen that inserts copyright/license boilerplate. AFAIK it's silly to pretend that machine generated files like these can be copyrighted or need license boilerplate. The XDR source files have their own copyright and license; and their copyrights are bound to be more up to date than old boilerplate inserted by a script. From what I've seen of other Open Source projects -- e.g. gcc and its C parser files generated by yacc and lex -- IIRC they don't bother to add copyright/license boilerplate to their generated files. It appears that it's a long-standing feature of make (SysV, BSD, gnu) for out-of-tree builds to helpfully pretend that the source files it can find in the VPATH "exist" as if they are in the $cwd. rpcgen doesn't work well in this situation and generates files with "bad" #include directives. E.g. if you `rpcgen ../../../../$srcdir/rpc/xdr/src/glusterfs3-xdr.x`, you get an #include directive in the generated .c file like this: ... #include "../../../../$srcdir/rpc/xdr/src/glusterfs3-xdr.h" ... which (obviously) results in compile errors on out-of-tree build because the (generated) header file doesn't exist at that location. Compared to `rpcgen ./glusterfs3-xdr.x` where you get: ... #include "glusterfs3-xdr.h" ... Which is what we need.

* features/locks: Add lock revocation functionality to posix locks translatorRichard Wareing2016-07-187-8/+321
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: - Motivation: Prevents cluster instability by mis-behaving clients causing bricks to OOM due to inode/entry lock pile-ups. - Adds option to strip clients of entry/inode locks after N seconds - Adds option to clear ALL locks should the revocation threshold get hit - Adds option to clear all or granted locks should the max-blocked threshold get hit (can be used in combination w/ revocation-clear-all). - Options are: features.locks-revocation-secs <integer; 0 to disable> features.locks-revocation-clear-all [on/off] features.locks-revocation-max-blocked <integer> - Adds monkey-locking option to ignore 1% of unlock requests (dev only) features.locks-monkey-unlocking [on/off] - Adds logging to indicate revocation event & reason Test Plan: First you will need TWO fuse mounts for this repro. Call them /mnt/patchy1 & /mnt/patchy2. 1. Enable monkey unlocking on the volume: gluster vol set patchy features.locks-monkey-unlocking on 2. From the "patchy1", use DD or some other utility to begin writing to a file, eventually the dd will hang due to the dropped unlocked requests. This now simulates the broken client. Run: for i in {1..1000};do dd if=/dev/zero of=/mnt/patchy1/testfile bs=1k count=10;done' ...this will eventually hang as the unlock request has been lost. 3. Goto another window and setup the mount "patchy2" @ /mnt/patchy2, and observe that 'echo "hello" >> /mnt/patchy2/testfile" will hang due to the inability of the client to take out the required lock. 4. Next, re-start the test this time enabling lock revocation; use a timeout of 2-5 seconds for testing: 'gluster vol set patchy features.locks-revocation-secs <2-5>' 5. Wait 2-5 seconds before executing step 3 above this time. Observe that this time the access to the file will succeed, and the writes on patchy1 will unblock until they hit another failed unlock request due to "monkey-unlocking".

* posix/lock: implement meta-lock/unlock functionalitySusant Palai2016-06-035-27/+462
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | problem : The lock state needs to be protected when rebalance is reading the lock state on the source. Otherwise there will be locks left unmigrated. Hence, to synchronize incoming lock requests with lock-migration, meta lock is needed. Any new lock request will be queued if there is an active meta-lock and with sucessful lock migration, will be unwound with EREMOTE, so that dht module can wind the request to the correct destination. On a successful lock migration, "pl_inode->migrated" flag is enabled. Hence, any further request would be unwound with EREMOTE and will be redirected to new destination.

* cluster/ec: Rebalance hangs during renameAshish Pandey2016-03-305-50/+177
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: During the rename of a particular file (ec is holding blocking inodelk on the parent directory), if the rename of another file under the same directory comes. EC does not release the lock and goes ahead and renames the "new" file with the "already held lock". That causes rebalance process to be blocked on a lock which has been acquired by rename. Solution: While rename fop comes, ec takes blocking inodelk on old and new parent of the file. Before releasing, every lock held by ec, it waits for some "time" to see if that lock can be reused by the next fop. If within this "time" some other request comes, it releases this lock based on condition "lock count > 1" To get this "lock count" for rename fop, we have implemented "pl_rename" in feature/lock. Also, on ec side, changed the condition to release the lock based on the type of fop and old and new parent directories.
