* libglusterfs: Move devel headers under glusterfs directoryShyamsundarR2018-12-05130-386/+395
| | | | | | | | | | | | | | | | | | | | | | | | libglusterfs devel package headers are referenced in code using include semantics for a program, this while it works can be better especially when dealing with out of tree xlator builds or in general out of tree devel package usage. Towards this, the following changes are done, - moved all devel headers under a glusterfs directory - Included these headers using system header notation <> in all code outside of libglusterfs - Included these headers using own program notation "" within libglusterfs This change although big, is just moving around the headers and making it correct when including these headers from other sources. This helps us correctly include libglusterfs includes without namespace conflicts.

* rpc: bump up server.event-threadsMilind Changire2018-12-041-1/+1
| | | | | | | | | | | | | | | Problem: A single event-thread causes performance issues in the system. Solution: Bump up event-threads to 2 to make the system more performant. This helps in making the system more responsive and helps avoid the ping-timer-expiry problem as well. However, setting the event-threads to 2 is not the only thing required to avoid ping-timer-expiry issues.

* rpcsvc: provide each request handler thread its own queueRaghavendra Gowdappa2018-11-294-28/+125
| | | | | | | | | | | | | | | | | | | | | | | | | | | | A single global per program queue is contended by all request handler threads and event threads. This can lead to high contention. So, reduce the contention by providing each request handler thread its own private queue. Thanks to "Manoj Pillai"<mpillai@redhat.com> for the idea of pairing a single queue with a fixed request-handler-thread and event-thread, which brought down the performance regression due to overhead of queuing significantly. Thanks to "Xavi Hernandez"<xhernandez@redhat.com> for discussion on how to communicate the event-thread death to request-handler-thread. Thanks to "Karan Sandha"<ksandha@redhat.com> for voluntarily running the perf benchmarks to qualify that performance regression introduced by ping-timer-fixes is fixed with this patch and patiently running many iterations of regression tests while RCAing the issue.

* core: ctx calls naked calloc()Kaleb S. KEITHLEY2018-11-281-1/+1
| | | | | | | | | | | | | | | | liblglusterfs provides wrapper functions MALLOC/__gf_default_malloc, CALLOC/__gf_default_calloc, and REALLOC/__gf_default_realloc for those few places outside of mempool.c that need to call malloc/calloc/realloc directly. Notable exceptions are "contrib" code, e.g. rbtree and timer-wheel, and perhaps parsers generated by yacc+lex. But even parsers can be fixed to at least call the wrappers mentioned above, if not our own allocators.

* libglusterfs: fix memory corruption caused by per-thread mem poolsXavi Hernandez2018-11-261-57/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There was a race in the per-thread memory pool management that could lead to memory corruption. The race appeared when the following sequence of events happened: 1. Thread T1 allocated a memory object O1 from its own private pool P1 2. T1 terminates and P1 is marked to be destroyed 3. The mem-sweeper thread is woken up and scans all private pools 4. It detects that P1 needs to be destroyed and starts releasing the objects from hot and cold lists. 5. Thread T2 releases O1 6. O1 is added to the hot list of P1 The problem happens because steps 4 and 6 are protected by diferent locks, so they can run concurrently. This means that both T1 and T2 are modifying the same list at the same time, potentially causing corruption. This patch fixes the problem using the following approach: 1. When an object is released, it's only returned to the hot list of the corresponding memory pool if it's not marked to be destroyed. Otherwise the memory is released to the system. 2. Object release and mem-sweeper thread synchronize access to the deletion mark of the memory pool to prevent simultaneous access to the list. Some other minor adjustments are made to reduce the lengths of the locked regions.

* Coverity fix for calling risky function - fscanfPoornima G2018-11-242-7/+7
| | | | | | | | | | | | | | | fscanf with %s reads a word, there is no restriction on the length of that word, and the caller is required to pass a sufficiently large buffer for storing thw word. If the input word exceeds the buffer size, it will cause buffer overflow. To fix this, use fscanf with width parameter. Width specifies the maximum number of characters to be read in the current reading operation.

Corresponding infrastructure to add per xlator log-level is not present in glusterd volume-set. Plan is to get it sorted out in later patches or in GD2. * Why this is needed? - Mainly because we need to only add different log-level to some xlator to debug few things in a production system, while not changing overall log-level.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The #include "uuid.h" left over from using .../contrib/uuid is debatably incorrect now that we use the "system header" file /usr/include/uuid/uuid.h from libuuid-devel. Unfortunately this is complicated by things like FreeBSD having its own /usr/include/uuid.h, and the e2fsprogs-libuuid uuid.h in installed - as most third-party packages in FreeBSD are - in /usr/local as /usr/local/include/uuid/uuid.h With a system header file it should at least be #include <uuid.h>, and even better as #include <uuid/uuid.h>, much like the way <sys/types.h> and <net/if.h> are included. Using #include <uuid/uuid.h> guarantees not getting the /usr/include/uuid.h on FreeBSD, but clang/cc knows to find "system" header files like this in /usr/local/include; with or without the -I/... from uuid.pc. Also using #include "uuid.h" leaves the compiler free to find a uuid.h from any -I option it might be passed. (Fortunately we don't have any at this time.) As we now require libuuid-devel or e2fsprogs-libuuid and configure will exit with an error if the uuid.pc file doesn't exist, the HAVE_LIBUUID (including the #elif FreeBSD) tests in compat-uuid.h are redundant. We are guaranteed to have it, so testing for it is a bit silly IMO. It may also break building third party configure scripts if they omit defining it.

* glusterd/geo-rep: Fix memory corruptionKotresh HR2018-10-121-1/+1
| | | | | | | | | | | | | | | | | | | | Problem and Analysis: The length of canonical format of uuid is 36 but 'GF_UUID_BUF_SIZE 50' was being used everywhere. glusterd/geo-rep code was earlier using strncpy, but recently changes to memcpy with the drive to avoid strncpys. This leads to memory corruption and glusterd is crashing without a core with geo-rep creation with ASAN build. Fix: 'GF_UUID_BUF_SIZE 37' (+ 1 for NULL byte) And change geo-rep to use UUID_CANONICAL_FORM_LEN instead Updates: bz#1633930 Change-Id: Ibd347d542b92e64a96ce06780cda643557233bc7 Signed-off-by: Kotresh HR <khiremat@redhat.com>

* core: glusterfsd keeping fd open in index xlatorMohit Agrawal2018-10-121-13/+1
| | | | | | | | | | | | | | | | | | | | | | Problem: At the time of processing GF_EVENT_PARENT_DOWN at brick xlator, it forwards the event to next xlator only while xlator ensures no stub is in progress. At io-thread xlator it decreases stub_cnt before the process a stub and notify EVENT to next xlator Solution: Introduce a new counter to save stub_cnt and decrease the counter after process the stub completely at io-thread xlator. To avoid brick crash at the time of call xlator_mem_cleanup move only brick xlator if detach brick name has found in the graph Note: Thanks to pranith for sharing a simple reproducer to reproduce the same fixes bz#1637934 Change-Id: I1a694a001f7a5417e8771e3adf92c518969b6baa Signed-off-by: Mohit Agrawal <moagrawal@redhat.com>

* socket: use accept4/paccept for nonblocking socketKrishnan Parthasarathi2018-10-123-0/+65
| | | | | | | | | | | | | | | | | This reduces the no. of syscalls on Linux systems from 2, accept(2) and fcntl(2) for setting O_NONBLOCK, to a single accept4(2). On NetBSD, we have paccept(2) that does the same, if we leave signal masking aside. Added sys_accept which accepts an extra flags argument than accept(2). This would opportunistically use accept4/paccept as available. It would fallback to accept(2) and fcntl(2) otherwise. While at this, the patch sets FD_CLOEXEC flag on the accepted socket fd.

| | | | | | | | | | | | | | | | | | I did not see a good reason to copy the temp strings str1 and str2 into msg string, and just used str1 (sprintf'ed str2 into it first). Hope it makes logging somewhat faster, but I also hope there's more room for improvement for faster logging. Renamed str1 to logline and str2 to msg for better readability. Also, remove dead assignment in _gf_msg() (clang complained).
